Description

Technical Field

[0001] The utility model relates to the technical field of sand spraying machines, in particular to a self-cleaning sand spraying machine. Background Art

[0002] A sand spraying machine is a device that plays an important role in industrial production. In handicraft production, sand spraying can endow ceramic works with unique textures and appearances.

[0003] Currently, a sand blasting machine includes a sand blasting device and a sand lifting device. During operation, sand is supplied into the sand blasting device and then glass is processed. Since in order to reduce abnormal noises and ensure smooth feeding, there is a certain gap between both sides of the feeding belt and the machine frame. When the sand blasting device is working, the abrasive at the bottom is likely to accumulate in the gap. Driven by the feeding belt, it is easy to push the abrasive in this part into the joint gap on the processing platform and then fall to the bottom surface. When working for a long time, it is easy to cause the surrounding of the sand blasting machine to be covered with abrasive and dust. When the air flows around the sand blasting machine, the dust will be raised, resulting in a poor working environment and also causing a reduction in the amount of abrasive, resulting in waste.

[0004] The existing patent (publication number: CN208629259U), a self-cleaning sand blasting machine, includes a machine frame. A processing platform is provided on the machine frame. A sand blasting device and a sand sweeping device are installed on the processing platform. A sand lifting device connected to the sand blasting device is installed on one side of the machine frame. A feeding belt is installed between the sand blasting device and the processing platform. A joint gap is provided on the processing platform. A sand driving groove is installed at the bottom of the processing platform corresponding to the joint gap. The sand driving groove is communicated with the joint gap. A spiral shaft is installed in the sand driving groove. One end of the sand driving groove is communicated with the sand lifting device. When the sand in the sand blasting device flows away from the joint gap, the sand blasting machine with this structure can collect this part of the sand through the sand driving groove and then re-discharge it into the sand lifting device. The structure is simple, reducing abrasive waste and making the surrounding of the sand blasting machine cleaner and tidier.

[0005] Regarding the above problems, the existing patent gives a solution, but it lacks a structure for cleaning the inner side of the sand spraying machine body, resulting in the blockage of the sand spraying channel, causing production interruption and defective product rate, thereby reducing production efficiency.

[0006] Therefore, a self-cleaning sand spraying machine is proposed. Utility Model Content

[0007] The purpose of the utility model is to provide a self-cleaning sand spraying machine, which can solve the problem that the existing sand spraying machine lacks a structure for cleaning the inner side of the sand spraying machine body, resulting in the blockage of the sand spraying channel, causing production interruption and defective product rate, thereby reducing production efficiency.

[0008] To achieve the above object, the present utility model provides the following technical solutions: A self-cleaning sand spraying machine, including a sand spraying machine body, a sand blocking plate is welded inside the sand spraying machine body, a connecting mechanism is rotatably connected to the rear side of the sand spraying machine body, and a cleaning mechanism is communicated with the rear side of the connecting mechanism;

[0014] Preferably, a clamping groove is opened on the front side of the connecting turntable, and the clamping groove is rotatably connected to the surface of the rotating ring.

The clamping rotating ring realizes a tight connection with the air inlet hole and can rotate relatively. While ensuring gas transmission, it does not affect the rotation of the connecting turntable and the connection of the air inlet pipe. And the clamping rotating ring can fix and limit the air inlet pipe. The air inlet pipe transports the high-pressure gas generated by the high-pressure air pump to the connecting turntable and subsequent cleaning components, ensuring a stable supply of cleaning gas. The high-pressure air pump provides a powerful high-pressure gas power, providing sufficient energy support for the self-cleaning operation. The high-pressure pipe transports the high-pressure gas from the connecting turntable to the nozzle inside the sand blocking plate. Through the transmission of the high-pressure pipe, the gas pressure is maintained, thus ensuring the spraying effect at the nozzle. The nozzle sprays the high-pressure gas at a specific angle and range, forming a powerful air flow to effectively clean the inside of the sand spraying machine;

[0019] 2. Compared with the existing self-cleaning sand spraying machine, this application achieves the cleaning of the inner side of the sand spraying machine body through the coordinated cooperation of the connecting mechanism and the cleaning mechanism, reducing the blockage of the sand spraying channel, resulting in production interruption and defective product rate, thereby improving production efficiency.

[0030] In this embodiment: By providing the sand spraying machine body 1, the sand blocking plate 2 and the connecting mechanism 3 can be supported and limited. By providing the sand blocking plate 2, the disorderly flow of sand grains can be blocked, so that the sand grains are more concentrated and evenly distributed during the sand spraying process, which helps to improve the sand spraying effect and quality. By providing the connecting turntable 301, it can rotate together with the sand blocking plate 2 when the sand blocking plate 2 rotates, and can support and limit the air inlet hole 302 and the limiting groove 303. By providing the air inlet hole 302, a channel for high-pressure gas to enter is provided to ensure that the gas generated by the high-pressure air pump 402 can be smoothly transmitted to the inside of the high-pressure pipe 403.

By providing the clamping rotating ring 304, a tight connection with the air inlet hole 302 is achieved and relative rotation can be performed. While ensuring gas transmission, it does not affect the rotation of the connecting turntable 301 and the connection of the air inlet pipe 401, and the clamping rotating ring 304 can fix and limit the air inlet pipe 401.

[0031] Specifically, as Figure 3 , Figure 4 , Figure 5As shown, the cleaning mechanism 4 includes an air inlet pipe 401, a high-pressure air pump 402, a high-pressure pipe 403, and a nozzle 404. The air inlet pipe 401 is fixedly connected to the inner side of the clamping rotating ring 304, and the air inlet pipe 401 communicates with the clamping rotating ring 304.

[0032] Specifically, as Figure 3 , Figure 4 , Figure 5 shown, the high-pressure air pump 402 is bolted to the bottom of the sand spraying machine body 1.

[0033] Specifically, as Figure 3 , Figure 4 , Figure 5 shown, the high-pressure pipe 403 is fixedly connected to the front side of the connecting turntable 301. The side of the high-pressure pipe 403 away from the connecting turntable 301 penetrates through the sand blocking plate 2 and is fixedly connected to the inner side of the sand blocking plate 2. The nozzle 404 is fixedly connected to the side of the high-pressure pipe 403 penetrating through the sand blocking plate 2. The high-pressure pipe 403 communicates with the connecting turntable 301 and the sand blocking plate 2, and the nozzle 404 communicates with the high-pressure pipe 403.

[0034] In this embodiment: By setting the air inlet pipe 401, the high-pressure gas generated by the high-pressure air pump 402 is transported to the connecting turntable 301 and subsequent cleaning components to ensure the stable supply of cleaning gas. By setting the high-pressure air pump 402, powerful high-pressure gas power is provided to provide sufficient energy support for the self-cleaning operation. By setting the high-pressure pipe 403, the high-pressure gas is transported from the connecting turntable 301 to the nozzle 404 inside the sand blocking plate 2. Through the transmission of the high-pressure pipe 403, the gas pressure is maintained, thus ensuring the spraying effect at the nozzle 404. By setting the nozzle 404, the high-pressure gas is ejected at a specific angle and range to form a strong air flow to effectively clean the inside of the sand spraying machine.

[0035] Specifically, as Figure 4 shown, a rotating ring 5 is bolted to the rear side of the sand spraying machine body 1, and the surface of the rotating ring 5 is coated with a lubricant.

[0036] Specifically, as Figure 4 shown, a clamping groove 6 is formed on the front side of the connecting turntable 301, and the clamping groove 6 is rotatably connected to the surface of the rotating ring 5.

[0037] In this embodiment: By providing a swivel ring 5, it helps the connecting turntable 301 to rotate more smoothly, reduces the frictional resistance during rotation, improves the flexibility and stability of rotation.

By providing a clamping groove 6, in cooperation with the swivel ring 5, it provides an accurate rotation track and positioning for the connecting turntable 301, preventing the connecting turntable 301 from shifting or wobbling during rotation.

[0038] Specifically, as Figure 4 shown, a sealing ring 7 is bolted to the rear side of the high-pressure air pump 402, and one side of the sealing ring 7 away from the high-pressure air pump 402 is bolted to the bottom of the air inlet pipe 401.

[0041] Working principle: First, the user places the sand spraying machine body 1 in an appropriate working position. Then, during the sand spraying operation, the sand blocking plate 2 welded inside the sand spraying machine body 1 starts to function. It can block the disorderly flow of sand grains, making the sand grains more concentrated and evenly distributed during the sand spraying process. After that, the connecting turntable 301 is rotatably connected to the rear side of the sand spraying machine body 1. When the sand blocking plate 2 rotates, the connecting turntable 301 can rotate accordingly. During this process, the clamping swivel ring 304 is rotatably connected inside the limiting groove 303 and can rotate relative to each other, ensuring the smooth transmission of gas while not affecting the rotation of the connecting turntable 301 and its connection to the air inlet pipe 401 at all. Then, when the user needs to clean the inside of the sand spraying machine body 1, the user powers on and starts the high-pressure air pump 402. The high-pressure gas generated by the high-pressure air pump 402 is guided through the air inlet pipe 401 to the inside of the connecting turntable 301. The connecting turntable 301 then guides the high-pressure gas to the inside of the high-pressure pipe 403. The high-pressure pipe 403 then guides the high-pressure gas to the nozzle 404. The nozzle 404 immediately sprays high-pressure gas on the inside of the sand blocking plate 2 and the inside of the sand spraying machine body 1, thus realizing self-cleaning. Finally, after the cleaning work is completed, the user can turn off the high-pressure air pump 402.

[0042] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
