Manual glass-cutting machine

The manual glass cutting machine is the most traditional glass cutting machine. The entire machine consists of two parts: a glass conveyor belt and a cutting table. By operating the conveyor belt manually, the glass to be cut is transported to the cutting table for cutting with a blade. The advantage of this cutting machine is that it can cut relatively small pieces of special-shaped glass and process the glass into different shapes. The disadvantage is that cutting the glass into a unique shape requires a special mold, and the manual operation itself is time-consuming and labor-intensive, making mass production impossible.

Semi-automatic glass cutting machine

This kind of glass cutting machine is roughly the same as a manual cutting machine, but a semi-automatic button operation device is added to the cutting machine. Although it is still mainly used to cut special-shaped glass, and special molds need to be made in advance according to the shape of the glass, the size of the glass that can be processed is larger than that of a manual cutting machine. And because it uses pneumatic plus motor kinetic energy during cutting, it saves a lot of manpower, so the production efficiency is much higher than that of manual cutting machines.

Fully automatic glass cutting machine

This glass cutting machine is a step further than semi-automatic glass cutting machines. It consists of a chassis mechanism, a beam mechanism, a glass processing tabletop, a cutter head mechanism, a conveying mechanism, a mechanical positioning mechanism, an electrical control system, etc., and has a complex structure.

Its processing method is controlled by the computer software equipped with the machine, which directly draws and then performs the operation. In this way, you can set in advance whether to make square, round, or special-shaped glass through the computer, without making a mold in advance.

The most advanced form of this kind of cutting machine is the production line model. In addition to the film-loading table, computer cutting machine, and film-breaking machine, this model also has a film-unloading table. The whole process of the assembly line is computer-controlled, with a high degree of automation, and is suitable for long periods. It can handle large quantities of glass products and is easy to maintain.

When cutting with a fully automatic glass cutting machine, typesetting is required first, and then cutting, film removal, and other processes can be carried out. Not only is it required to discharge as many pieces as possible that meet the required shape on the original glass sheet to improve the utilization rate of raw materials, but it is also required that the typesetting operation is simple and easy to use. Mechanical interactive typesetting is the most commonly used and convenient way for operators to type and cut according to the work order on site.

Water jet glass cutting machine

This kind of glass cutting machine also operates fully automatically through computer control. But unlike traditional blade cutting, it uses high-pressure water cutting technology, mainly for thicker glass products. Various complex patterns are formed through computer numerical control. This cutting machine performs cold cutting without producing thermal deformation or thermal effects. It can ensure smooth incision and can be completed in one go without the need for secondary operations. Due to these advantages, it can also perform complex operations of drilling glass.

1. Before cutting, fill the fuel tank on the cutting table beam with clean kerosene or cutting aid, and then adjust the corresponding angle on the fuel tank so that the linoleum in the knife box is filled with kerosene or cutting aid.

2. Check that there are no white spots or scratches on the appearance of the glass to be cut.

3. Push the longitudinal beam, and then push the cross beam after returning to its position to prevent collision with each other.

4. Before starting the machine, check whether there is air leakage in the machine pipeline. If there is air leakage, never start the machine.

5. Turn on the power switch and check whether there are any obstacles on the working surface and guide rails. If there are any obstacles, they must be removed.

6. Two people lift the glass to be cut to the cutting table, making sure it is firmly attached to prevent shaking. Before lifting the glass, you must confirm that there are no cracks in the glass itself to avoid the phenomenon of automatic separation of the glass during lifting.

7. Press the blow button to make the glass float on the table and move freely.

8. After the glass is positioned, press the stop button, and then press the suction device to firmly fix the glass at the designated position to achieve the positioning effect.

9. When the cutting is completed, press the stop button and then press the air blow switch.

10. When the whole piece of glass that has been cut is moved to the breaking table, turn on the blowing motor of the breaking table before moving. Only after the first piece is confirmed to be qualified can it be mass-produced. When measuring, the first row horizontally and vertically is used as the measurement object, and a full inspection is performed if necessary.

11. Divide the dough into small pieces horizontally and vertically according to the knife marks, and place the remaining material in the designated position. Stack the broken pieces of glass neatly and place them on the glass shelf.

12. Before shutting down, close all air valves and vent the remaining gas in the air circuit. If a backfire is found in the pipeline, the power and gas must be cut off immediately.

13. Use a rag to clean the glass fragments on the cutting table and breaking table.

Looking at the automatic glass cutting machines on the market, there are many models. What should we pay attention to during the purchase process? Let the LIJIANG Glass's technical experts explain it to you.

It seems that the model of the automatic glass cutting machine is composed of a simple string of letters and numbers, but it represents the factory age, technical equipment, and other contents of the cutting machine, so you should first determine which series of equipment you want to buy, and then distinguish the differences between different models. After all, each customer will set a budget first, and then purchase a cost-effective machine under a reasonable budget.

In addition, you should also look at the specific parameters of the automatic glass cutting machine, such as the cutting efficiency and the whole machine service mode. These parameters determine whether the equipment is convenient to use and the technical level of the equipment itself. What we have to do is to purchase machines with high precision and high speed as much as possible, so as not to delay future use.

The above are the precautions for purchasing automatic glass-cutting machines. In fact, in addition to purchasing specialists, if you can bring factory technicians, they come from the front line of operation, will be very familiar with the technology and use of the cutting machine, and will also give reasonable suggestions during the trial to avoid detours.

People can visit several automatic glass cutting machine manufacturers and compare automatic glass-cutting machines of different models and batches. I believe that they will have a deeper understanding of the industry and will be more adept at purchasing.

The automatic glass cutting line can simplify the glass cutting process and make the business process more efficient. Specifically, it is divided into several parts, including equipment framework, transmission, and other systems, as well as vacuum adsorption, mechanical flipping, electrical control, and other systems. People should compare the characteristics and usage methods of each system before purchasing, and choose a more cost-effective line.

To judge the performance of the glass cutting line, you need to look at the material of the whole machine to see if it has passed the national standard. At the same time, you should also judge the details, such as whether it has been oxidized to prevent rust. Is the vacuum degree and reliability achieved? If a system is not set up perfectly, it will inevitably affect the operation of the entire line, so you must be careful when checking.

For technicians, people especially hope that the glass cutting line has a one-button reset function, so that there is no need to operate it repeatedly, and it can also speed up the timeliness and speed of preparation work. For safety reasons, the equipment especially needs to have an alarm device, so that an alarm can be issued when the operation is not professional. People can repair and maintain according to the alarm, and they can also have a better understanding of the machine equipment.

The glass cutting line is relatively complex, and its mechanical configuration is very complete. Most of them adopt high-precision and high-density designs, which not only beautify the compactness of the appearance but also do not affect everyone's use. The indicators for reference when purchasing include the external dimensions, the size and thickness of the film, the film retrieval cycle, and also include power supply, power, etc.

The above is a specific introduction to the glass cutting line. It can be seen that the requirements for purchasing personnel are very high. Only by fully understanding the various components of the line can the purchase process be handy and the budget can be made to meet the factory's expectations. At present, many glass-cutting line manufacturers will carry out structural optimization work, to continuously upgrade technology and launch new products.
