LIJIANG Glass LJPS-1600 / LJPS-2000/ LJPS-2500 Automatic Vertical Glass Sandblasting Machine sucks the sandblasting medium from the sandblasting material box through compressed air, and then sprays it out through the sandblasting gun. When compressed air flows through the sandblasting gun, the air flow speed is accelerated by the shrinkage and expansion of the nozzle, forming a high-speed airflow. Under the action of air flow, the sandblasting medium is accelerated and ejected, impacting the surface of the workpiece for grinding and removing surface dirt. The sandblasting material box and sandblasting pipeline system of the sandblasting machine need to ensure the smoothness and stability of the sandblasting medium to ensure the sandblasting effect.

Automatic Vertical Glass Sandblasting Machine


LIJIANG Glass LJPS-1600 / LJPS-2000/ LJPS-2500 Automatic Glass Sandblasting Machine designed according to the marketing requirement that is controlled by the PLC, suitable for processing 5-40mm thickness of flat glass to different kinds of frosting patterns. The transmission is controlled by the photo switch and limit switch automatically. Glass is conveyed by the belt, and the guns are driven by a chain so that can be moved up and down for sandblasting (the distance can be adjusted according to the requirement). Stable transmission, high efficiency, and easy maintenance of the chain system. There is a dust-proof cover for the bearing that is onto the drive structure is beneficial to the long period of normal working conditions and daily maintenance. Adopt the PLC for control. The kinds of equipment are with the function of stable running, large-scale function, and easy operation, and can explore the glass position automatically when sandblasting. 

Automatic Vertical Glass Sandblasting Machine

Upgrade transmission by frequency conversion control, which can move forward or backward while sandblasting, and with function of gradual Change Sandblasting Processing----Sandblasting depth from shallow to deep. 

The equipment has two modes: fully automatic and manual. The machine is equipped with three automatic guns and one manual gun. The lifting of the gun and the transmission of glass are all PLC automatic control by a synchronous belt transmission, the transmission is stable and durable, and the gun lifting device is located outside of the body. Low failure rate. We have modified and upgraded the control program of the machine to facilitate more customers with special requirements.

Daily Maintenance 

1. After the equipment run a certain time, each conveyor belt will be elongate and should be strained promptly to avoid any problem to affect the performance of equipment. 

2. It should be add the cerium oxide and clean up the air collector regularly according to the producing condition. 

3. Please checks the height of oil level of each motors regularly which if less than 1/3 shouldbe adding the clean normal gear oil. In generally should be change all the lubricating oil of each mechanical driving parts each 6 months, the stepless regulator should adopt the #350 oil. 

4. The main drive sprocket and bearing etc. should be change the grease each 3-4months, adopt the ZG-2H lime grease.

5. Each rubber belt will be distortion and ageing because of pulling force when equipment was use longtime. It should be change the belt regularly to avoid any problem affect the efficiency and performance of equipment
