[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] Reference Figure 1-Figure 3 The utility model provides an embodiment: a sandblasting uniform device for a glass sandblasting machine, including a support frame 1, which serves as the supporting frame of the entire equipment and provides an installation basis for components such as a motor 2, a conveyor belt 3, and a sandblasting box 5. A motor 2 is installed on the outside of the support frame 1 to provide a power source, drive the conveyor belt 3 to operate, and drive other components to work through a belt transmission. A conveyor belt 3 is installed on the inside of the support frame 1 for conveying glass to achieve continuous sandblasting operations. Both ends of the inner transmission roller of the conveyor belt 3 are fixedly connected to a pulley 4, the output end of the motor 2 is fixedly connected to the outer side of the front pulley 4, and the top of the support frame 1 is fixedly connected to a sandblasting box. The box 5 provides a closed space for sandblasting operations to prevent sand from splashing. A sandblasting assembly is provided inside the sandblasting box 5. A sand bucket 12 is fixedly connected to the top of the sandblasting box 5 to store sand and provide a sand source for the sandblasting device 11. A transmission rod 13 is rotatably connected to the inside of the sand bucket 12. One end of the transmission rod 13 is fixedly connected to a pulley three 14. A belt is provided on the outer periphery of the pulley three 14 and the rear pulley one 4. A plurality of stirring blades 15 are fixedly connected to the outside of the transmission rod 13 to prevent the sand in the sand bucket 12 from agglomerating and ensure that the sand enters the sandblasting device 11 smoothly. A dust removal assembly is provided on the outside of the sandblasting box 5. The dust removal assembly is used to remove dust generated by sandblasting.
[0023] Specifically, during the glass sandblasting operation, the glass to be processed needs to be placed steadily on the surface of the conveyor belt 3, and then the motor 2 is started. The motor 2 begins to rotate and drives the conveyor belt 3 to perform the transmission operation. During this process, the two pulleys 1 4 play a transmission role. They respectively drive the rotation of the pulley 2 6 and the pulley 3 14 through the belt. When the pulley 3 14 rotates, it will also drive the transmission rod 13 connected to it. At this time, the multiple stirring blades 15 fixed to the transmission rod 13 will continuously stir the bottom position of the sand bucket 12, which can effectively prevent the sand from being agglomerated due to long-term rest or other factors, thereby avoiding the interruption of material feeding and ensuring that the sand particles can be continuously and stably supplied to the sandblasting device 11 during the sandblasting operation.
[0024] Reference Figure 1-Figure 3 The sandblasting assembly includes two sets of fixed blocks 8, supporting slide bars 9, which provide guide and support for the sandblasting device 11. The two sets of fixed blocks 8 are fixedly connected to both sides of the inner wall of the sandblasting box 5, and the number of each set of fixed blocks 8 is two. The inner sides of the two fixed blocks 8 are slidably connected with slide bars 9, and the outer sides of the two slide bars 9 are fixedly connected with the sandblasting device 11. The top of the sandblasting device 11 is connected to the bottom of the sand bucket 12 through a conduit. The outer sleeve of the slide bar 9 is provided with a spring 10 for quickly resetting the sandblasting device 11. One end of the spring 10 is fixedly connected to the outer side of the sandblasting device 11, and the other end of the spring 10 is fixedly connected to the outer side of the fixed block 8. The outer side of the sandblasting box 5 is rotatably connected to a pulley 2 6, and a cam 7 is fixedly connected to the outer rotating shaft of the pulley 2 6, pushing the slide bar 9 to make the sandblasting device 11 reciprocate. The outer periphery of the pulley 2 6 and the pulley 1 4 is provided with a belt, and the outer side of the cam 7 is in contact with one end of the front slide bar 9.
[0025] Specifically, when the pulley 2 6 rotates, the cam 7 will rotate accordingly. During the rotation of the cam 7, the protruding part of the cam 7 will periodically contact the slide bar 9 and push the slide bar 9 to move. When the protruding part of the cam 7 leaves the slide bar 9, under the elastic force of the spring 10, the slide bar 9 will quickly reset the sandblasting device 11. In this way, the sandblasting device 11 can achieve a small swing during the sandblasting process. This swing can not only expand the coverage of the sandblasting, but also make the sand particles more evenly sprayed onto the glass surface, thereby deepening the sandblasting effect, so that the glass surface can obtain a more ideal sandblasting treatment effect, both in terms of texture uniformity and depth. It can meet the process requirements.
[0026] Reference Figure 1-Figure 3The dust removal assembly includes a dust removal box 16, which collects dust generated during the sandblasting process. The dust removal box 16 is fixedly connected to the outside of the sandblasting box 5. An exhaust fan 20 is installed on the top of the dust removal box 16. A plurality of mounting holes 17 are provided inside the dust removal box 16. A filter bag 18 is provided on the inner side of the mounting hole 17 to filter dust and purify the air. An annular frame is provided inside the filter bag 18 to support the filter bag 18 and prevent the filter bag 18 from deforming. A through opening is provided on one side of the dust removal box 16, and a baffle 19 is provided on the outside of the through opening. A connecting port 21 is provided on the top of the sandblasting box 5 to connect the sandblasting box 5 and the dust removal box 16 so that dust can enter the dust removal box 16.
[0027] Specifically, when the sandblasting operation is in progress, a large amount of dust will be generated. This dust will enter the interior of the dust removal box 16 through the connecting port 21 opened on the top of the sandblasting box 5. The exhaust fan 20 is started. After the exhaust fan 20 is running, a negative pressure environment will be formed inside the dust removal box 16. Under the action of the negative pressure, the dust will be adsorbed and attached to the outer surface of the filter bag 18. When there is a lot of dust attached to the outer surface of the filter bag 18, in order to ensure the dust removal effect, the exhaust fan 20 can be switched to the blowing mode. In the blowing mode, the strong airflow will blow the filter bag 18 to shake. When the filter bag 18 is shaken, the dust on its outside will fall off due to the vibration and fall along the inclined surface of the sandblasting box 5 to the bottom layer of the dust removal box 16. When the dust accumulated inside the dust removal box 16 reaches a certain amount, the operator can open the baffle 19 to conveniently clean out the dust accumulated inside the dust removal box 16. This not only ensures the continuous and effective operation of the dust removal system, but also provides a relatively clean working environment for the sandblasting operation, reduces the impact of dust on equipment and operators, and also meets environmental protection requirements and avoids dust pollution to the surrounding environment.
[0028] Working principle: First, place the glass to be processed on the surface of the conveyor belt 3, start the motor 2 to drive the conveyor belt 3 for transmission, and at the same time, the two pulleys 4 respectively drive the pulley 2 6 and the pulley 3 14 to rotate through the belt, and the pulley 3 14 will drive the transmission rod 13 to rotate, so that the multiple stirring pieces 15 are constantly stirring at the bottom position of the sand bucket 12 to prevent the sand from being stretched and the material being discharged intermittently. The rotation of the pulley 2 6 will cause the cam 7 to rotate and push the slide rod 9 to move. Under the elastic force of the spring 10, the slide rod 9 will quickly reset the sandblasting device 11, so that the sandblasting device 11 can swing slightly during sandblasting to deepen the sandblasting effect.
[0029] In addition, the dust generated by sandblasting will enter the interior of the dust removal box 16 from the connecting port 21. Starting the exhaust fan 20 will form a negative pressure environment inside the dust removal box 16, and the dust will adhere to the outer surface of the filter bag 18. Switching the exhaust fan 20 to the blowing mode can blow the filter bag 18 to shake it, and the dust outside the filter bag 18 will fall along the inclined surface of the sandblasting box 5 to the bottom layer of the dust removal box 16. Opening the baffle 19 can clean the dust accumulated inside the dust removal box 16.
[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
