Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a sandblasting machine used for surface treatment of a computer shell. Background Art

[0002] A sandblasting machine is a machine that uses compressed air as a power source to form a high-speed jet beam to spray material (such as corundum, quartz sand, etc.) at high speed onto the surface of the workpiece to change the surface of the workpiece. When computer casings are produced, they need to be treated by a sandblasting machine. The sandblasting machine can make the surface of the computer casing rougher through the impact of high-speed sand flow. This roughening treatment helps to improve the adhesion of the casing surface to other coatings or materials, making the coating more firmly attached to the casing and not easy to fall off. This is crucial for subsequent processing processes such as painting and electroplating of the computer casing.

[0003] When using an existing sandblasting machine, the operator needs to always pay attention to the position of the workpiece and the personnel, and manually control the start and stop of the sandblasting nozzle when appropriate. This not only increases the operating burden, but may also cause distraction, affecting work efficiency and safety.

[0004] For example, a mold surface cleaning sandblasting machine disclosed in the announcement number CN211517169U does not have the function of automatically controlling the start and stop of the sandblasting gun. The operator needs to manually control the start and stop of the sandblasting operation. Manual control may lead to poor synchronization between the sandblasting operation and operations such as workpiece movement and personnel evacuation, thus lacking automatic control function. It will not only reduce the automation level and intelligence of the production line, but also require more manual intervention and monitoring, which may also lead to an increase in production costs.

[0005] Therefore, it is necessary to invent a sandblasting machine that is used for the surface treatment of computer housing to solve the above problems. Utility Model Content

The spray gun can spray the entire surface evenly and continuously, ensuring the spraying quality while improving the spraying efficiency, thereby improving the spraying efficiency;

[0017] 2. Through the setting of the contactor and the switch button, when the workbench moves out, the contactor on the workbench is away from the switch button inside the sandblasting machine, automatically cutting off the sandblasting operation of the spray gun, avoiding the risk of continuing the sandblasting operation when the operator or the workpiece has not fully entered the safe area. This significantly reduces safety accidents caused by misoperation or unexpected situations. The operator only needs to move the workbench to the specified position without manually controlling the start and stop of the sandblasting nozzle, which simplifies the operation process. The automatic contact and disconnection of the contactor and the switch button realizes the automatic control of the sandblasting operation and improves work efficiency.

[0027] An X-axis sliding module 3 is arranged at the top inner part of the sandblasting machine body 1, a slide 4 is arranged on the X-axis sliding module 3, the X-axis sliding module 3 and the slide 4 are slidingly connected, a spray gun 5 is arranged below the slide 4, a sandblasting tube 6 is connected to the spray gun 5 and extends through the sandblasting machine body 1 to the inside of the sand storage hopper 2, the discharge end of the sand storage hopper 2 is connected to the feed end of the sandblasting tube 6, and the feed end of the spray gun 5 is connected to the discharge end of the sandblasting tube 6.

[0028] A sliding connection mechanism is formed between the slide 4 and the X-axis sliding module 3 to ensure that the slide 4 and the spray gun 5 below can move smoothly and stably in the horizontal direction, thereby realizing accurate sandblasting operation on the surface of the computer housing. The sand storage hopper 2 serves as a storage container for sand material, and its discharge end is tightly connected with the feed end of the sandblasting tube 6 to ensure continuous supply of sand material to the spray gun 5.

[0029] There are two guide rails 9, and sliding seats 11 are arranged above the two guide rails 9. The guide rails 9 and the sliding seats 11 are slidably connected, the feed port 7 and the sealing door 12 are snap-fitted, and a sealing gasket is arranged between the connection between the feed port 7 and the sealing door 12. The side wall of the sealing door 12 is connected to the output end of the hydraulic cylinder 13, and the cylinder in the cylinder housing 14 is connected to the electronic control chassis 18 through the electronic control system.

[0031] Working principle of this utility model:

[0032] Refer to the instruction manual Figure 1-5 When using the utility model, first place the computer housing on the workbench 10, and clamp the computer housing through the cylinder driving clamp 15 inside the cylinder housing 14, then turn on the power switch of the electronic control box 18 to start the whole system, at this time, the hydraulic cylinder 13 drives the workbench 10 and the sealing door 12 to move inside the sandblasting machine body 1, when the workbench 10 moves to a specific position, the sealing door 12 and the feed port 7 are locked and closed, and at the same time, the contactor 16 contacts the switch button 17 with the movement of the workbench 10, so that the switch button 17 is in a closed state, and this action triggers the electronic control system, and then controls the spray gun 5 of the sandblasting machine to start working, and the spray gun 5 is continuously moved under the drive of the X-axis sliding module 3 and the slide 4 to perform the sandblasting operation;

[0033] On the contrary, when the sandblasting operation is completed, the hydraulic cylinder 13 drives the workbench 10 and the sealing door 12 to move outward and away from the inside of the sandblasting machine body 1. As the workbench 10 moves, the contactor 16 moves away from the switch button 17, causing the switch button 17 to automatically return to the disconnected state, thereby controlling the spray gun 5 of the sandblasting machine to stop working. In this way, the start and stop of the spray gun 5 of the sandblasting machine are automatically controlled without the need for manual intervention by the operator. This design effectively avoids the risk of the sandblasting operation continuing when the operator or the workpiece has not completely entered the safe area, significantly improving the safety and efficiency of the operation;

[0034] After the computer housing that has been sandblasted is moved out of the sandblasting machine body 1 as the workbench 10 moves, the cylinder in the cylinder housing 14 drives the clamping plate 15 to release the computer housing, and the operator can remove the computer housing that has been sandblasted and continue to load the material for the next round of sandblasting.
