Detailed Implementation

[0029] To facilitate understanding of this utility model, a more comprehensive description of this application will be given below with reference to the accompanying drawings, which show preferred embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this utility model.

[0030] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] like Figures 1 to 4 As shown, this application provides a grinding device for hardware processing, including a grinding cylinder 100 and a support frame 110. The grinding cylinder 100 is a hollow cylinder with its two ends movably connected to the support frame 110. Abrasive powder is added inside the grinding cylinder 100.

[0033] A drive motor 111 is fixed on the support frame 110 at the original location of the grinding cylinder 100. The drive motor 111 is used to drive the grinding cylinder 100 to rotate.

[0034] The grinding cylinder 100 has a discharge port 1001 on its end face. A movable door is hinged to the discharge port 1001. The movable door is used to isolate the abrasive powder inside the grinding cylinder 100, so that the hardware is not easily thrown out during the grinding process. Open the movable door to put the hardware into the grinding cylinder 100, and then open the movable door to take out the hardware.

[0035] A collection chamber 150 is fixed to the bottom side of the grinding cylinder 100. A screen 154 is installed inside the collection chamber 150. The aperture of the screen 154 is not larger than the size of the hardware and not smaller than the particle size of the abrasive powder.

[0036] It is worth noting that the abrasive powder can enter the collection chamber 150 and pass through the screen 154 to intercept the hardware, separating the hardware from the abrasive powder and making it easier to remove the hardware.

[0037] Specifically, such as Figures 1 to 4 As shown, the grinding cylinder 100 has an opening on its side near the collection chamber 150, and the sealing plate 140 is located at the opening of the grinding cylinder 100. The sealing plate 140 is used to isolate the abrasive powder inside the grinding cylinder 100, so that the abrasive powder does not easily enter the collection chamber 150 when the grinding cylinder 100 rotates.

[0038] Specifically, such as Figures 1 to 4 As shown, the grinding cylinder 100 has a groove, a compression spring 142 is fixed in the groove, and a telescopic plate 141 is fixed to the empty end of the compression spring 142.

[0039] The unused end of the telescopic plate 141 is fixed to the sealing plate 140. A movable plate is fixed on the telescopic plate 141. The movable plate extends out of the grinding cylinder 100, and an arc-shaped groove is opened on the end face of the grinding cylinder 100. The movable plate is located in the arc-shaped groove.

[0040] It is easy to understand that when separating the abrasive powder and the hardware, by pulling the moving plate in the arc-shaped groove, the telescopic plate 141 can be moved towards the compression spring 142, and the sealing plate 140 can be retracted into the groove.

[0041] Specifically, such as Figures 5 to 8 As shown, a gas soft bag 151 is fixed on the inner side of the collection chamber 150. There are two gas soft bags 151, and the two gas soft bags 151 are parallel.

[0042] Each of the gas soft bags 151 has a partition plate 152 fixed on its side, and a venting tube 153 fixed on the collection chamber 150.

[0043] The vent pipe 153 has two outlet ends. One outlet end of the vent pipe 153 extends into a gas soft bag 151. An inlet pipe 1531 is fixed on the inlet end of the vent pipe 153. The remaining end of the inlet pipe 1531 is connected to an air pump, which is fixed on the collection chamber 150.

[0044] It should be noted that in the initial state, the gas soft bag 151 is in an inflated state, which makes the two isolation plates 152 press against each other. In this way, the abrasive powder will not be spilled when the collection chamber 150 rotates. The air inlet pipe 1531 inflates the air vent pipe 153, the gas soft bag 151 expands, the air inlet pipe 1531 draws air out of the air vent pipe 153, and the gas soft bag 151 begins to contract.

[0045] Specifically, such as Figures 5 to 8 As shown, air is drawn into the ventilation pipe 153 through the air inlet pipe 1531, causing the gas soft bag 151 to contract and drive the isolation plate 152 to move apart.

[0046] The screen 154 is detachably connected to the collection chamber 150, meaning that the screen 154 can be removed for easy cleaning without affecting the abrasive powder's re-entry into the grinding cylinder 100.

[0047] Specifically, such as Figures 1 to 8 As shown, a mounting frame 120 is installed on one side of the support frame 110. The mounting frame 120 is a U-shaped frame, and a drive gear 121 is movably connected in its mounting space. A rotary motor 122 is installed on the mounting frame 120, and the rotary motor 122 is used to drive the drive gear 121 to rotate.

[0048] The grinding cylinder 100 is fitted with a rotating gear 130. There is a gap between the rotating gear 130 and the grinding cylinder 100. That is to say, when the grinding cylinder 100 rotates, it will not drive the rotating gear 130 to rotate. Similarly, when the rotating gear 130 rotates, it will not drive the grinding cylinder 100 to rotate. The rotating gear 130 and the drive gear 121 are meshed and connected.

[0049] In actual use, the metal processing grinding equipment of this application embodiment first places the metal parts in the grinding cylinder 100. The grinding cylinder 100 is rotated by the drive motor 111. The metal parts and abrasive powder continuously collide and scrape, thereby grinding and polishing the surface of the metal parts. After the metal parts are ground, the moving plate is pulled to move in the arc-shaped slide groove, which can drive the telescopic plate 141 to move towards the compression spring 142, and retract the sealing plate 140 into the groove. The air pump draws air into the air inlet pipe 1531, causing the gas soft bag 151 to contract and drive the isolation plate 152 to move, so that the abrasive powder and metal parts fall into the collection chamber 150. Then, the movable door is opened to take out the screen 154 and collect the ground metal parts.

[0050] After the hardware parts are polished, the abrasive powder is sent back into the polishing cylinder 100. At this time, the sealing plate 140 and the isolation plate 152 are in a sealed state. First, the drive motor 111 drives the polishing cylinder 100 to rotate 90°, and then the rotary motor 122 drives the drive gear 121 to rotate. The drive gear 121 drives the rotary gear 130 to rotate 90°. At this time, the sealing plate 140 and the isolation plate 152 are parallel. First, the sealing plate 140 is opened, and then air is drawn into the air inlet pipe 1531, causing the gas soft bag 151 to contract and drive the isolation plate 152 to move apart, pouring the abrasive powder into the polishing cylinder 100. Then, the polishing cylinder 100 and the collection chamber 150 are reset, and the screen 154 is installed into the collection chamber 150. Repeating the operation can achieve polishing of hardware parts, and at the same time, it can quickly separate hardware parts and abrasive powder, making it less likely for parts to be missed, improving work efficiency, reducing product loss, and ensuring product quality.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
