Description

Technical Field

[0001] This utility model relates to the field of hardware manufacturing and processing technology, and in particular to a hardware surface polishing device. Background Technology

[0002] Hardware refers to a category of metal products, including various metal parts, accessories, and components, such as screws, nuts, bolts, nails, hinges, door handles, etc. These parts are usually made of metal materials (such as steel, iron, copper, aluminum, etc.) and are used in the manufacturing and assembly of various industries such as construction, machinery, furniture, electronic equipment, and automobiles. During the processing of hardware, burrs are often produced, which are uneven, sharp, or protruding edges on the edges of the parts. The presence of burrs may affect the appearance, quality, safety, and functionality of the product. Therefore, polishing equipment is usually used to process hardware.

[0003] Because hardware parts come in various shapes and sizes, tumbler polishing machines are typically used for grinding and polishing. Tumbler polishing machines are suitable for deburring, removing rust, rounding, and bright polishing of large batches of different hardware parts. Existing polishing equipment involves placing abrasive particles and hardware parts into a tumbler, then driving the tumbler to rotate at high speed via a motor to polish the hardware parts. However, the unloading process of tumbler polishing machines requires the entire abrasive particle and hardware parts to be unloaded together and then sorted, which takes a long time and is not conducive to improving the efficiency of hardware polishing.

[0024] In one embodiment, such as Figures 1 to 4 As shown, a hardware surface polishing device 10 includes: a support frame 100, a roller 200, and a housing 300; the support frames 100 are symmetrically arranged on both sides of the upper surface of the housing 300, and the roller 200 is arranged between the two support frames 100 and rotatably connected to the support frames 100; one end of the roller 200 is provided with a drive wheel 220, and the middle of the roller 200 is provided with a feed port, which is provided with a detachable end cap 210; the upper surface of the housing 300 is provided with a hopper 310 communicating with the interior of the housing 300 and a first drive motor 320, the output end of the first drive motor 320 is fixedly connected to a drive wheel 321, and the drive wheel 321 is connected to the drive wheel 320 via a belt. Wheel 220 connection; the housing 300 is equipped with a screening component 400, a sweeping component 500 and a receiving component 600. The screening component 400 is located directly below the collecting hopper 310 and is equipped with a vibration motor 450. The sweeping component 500 includes a drive screw 510 and a second drive motor 530 located on one side of the screening component 400, and a guide rod 540 located on the opposite side of the screening component and the drive screw 510. The drive screw 510 is equipped with a slider 520, and a sweeping rod 550 is located between the slider 520 and the guide rod 540. The receiving component 600 is located below the screening component 400 and is used to receive the abrasive and workpiece falling from the screening component 400 respectively.

[0025] In this embodiment, two support frames 100 are symmetrically arranged on the upper surface of the housing 300. A roller 200 is positioned between the two support frames 100 and rotatably connected to them via a connecting shaft. A transmission wheel 220 is fixedly connected to one end of the roller 200. A feed inlet is provided in the middle of the roller 200 for easy loading and unloading of workpieces. The feed inlet is equipped with a removable end cap 210 to keep the inside of the roller 200 closed. A collecting hopper 310 and a first drive motor 320 are provided on the upper surface of the housing 300. The first drive motor 320 drives the transmission wheel 220 to rotate via a drive wheel 321 and a belt, thereby driving the roller 200 to rotate and achieve polishing of the workpiece. A screening assembly 400 is provided inside the housing 300. A vibration motor 450 is provided on the screening assembly 400, and a sweeping assembly 500 is positioned on the screening assembly 400. A collecting assembly 600 is positioned below the screening assembly 400. Thus, the roller 200... The polished workpieces are fed into the collecting hopper 310 and collected onto the screening assembly 400. The sieve holes on the screening assembly 400 have a diameter larger than the diameter of the abrasive but smaller than the diameter of the workpiece. The screening assembly 400 is driven to vibrate by the vibration motor 450, thereby separating the abrasive from the workpiece and allowing the abrasive to enter the receiving assembly 600 directly below the screening assembly 400. The sweeping assembly 500 includes a drive screw 510, a slider 520, a second drive motor 530, a guide rod 540, and a sweeping rod 550. The second drive motor 530 drives the drive screw 510 to rotate, causing the slider 520 on the drive screw 510 to push the sweeping rod 550 back and forth on the guide rod 540, thereby pushing the workpieces on the screening assembly 400 into the receiving assemblies 600 on both sides of the screening assembly 400. This achieves automatic separation and collection of the workpiece and the abrasive, improving work efficiency and reducing manual operation.

[0026] In one embodiment, a spiral guide plate 230 is provided inside the drum 200, and the spiral guide plate 230 is coaxially arranged with the drum 200. Specifically, in order to improve the uniform polishing effect of the workpiece inside the drum 200, a spiral guide plate 230 coaxially arranged with the drum 200 is provided inside the drum 200, so that the workpiece and abrasive continuously tumble when the drum 200 rotates, thereby enabling the workpiece to fully contact the abrasive and improving the grinding effect. The cross-section of the drum 200 is elliptical, and the diameter of the spiral guide plate 230 is smaller than the inner diameter of the drum 200, so that after the spiral guide plate 230 pushes the workpiece and abrasive to one end of the drum 200, they can be squeezed from below the spiral guide plate 230 to the other end, forming a circulating flow, ensuring that each workpiece is uniformly ground and improving the polishing quality.

[0027] In one embodiment, such as Figure 2 and Figure 3As shown, the screening component 400 includes an upper frame 410, a lower frame 430, and a screen 420 disposed on the upper frame 410; the vibration motor 450 is fixed on the upper frame 410; the upper frame 410 and the lower frame 430 are connected by a plurality of damping springs 440. Specifically, the screening component 400 includes a lower frame 430 fixed inside the housing 300, an upper frame 410 movably connected to the lower frame 430, and a screen 420 fixed on the upper frame 410. Multiple first connecting posts 431 are provided around the lower end of the lower frame 430, and second connecting posts 411 are provided on the upper frame 410 at positions corresponding to the first connecting posts 431. The first connecting posts 431 and the second connecting posts 411 are connected by a damping spring 440 to form an elastic support structure, effectively reducing vibration transmission. A vibration motor 450 is fixed on the upper frame 410, allowing the upper frame 410 to vibrate independently under the action of the vibration motor 450. The screen 420 vibrates along with the upper frame 410, causing the abrasive to pass through the screen holes and fall into the abrasive collection frame 610, while the workpiece is pushed to both sides by the sweeping rod 550 for precise separation and improved collection efficiency.

[0028] In one embodiment, the upper frame 410 is provided with inclined screen plates 460 at both ends perpendicular to the drive screw 510. Specifically, inclined downward screen plates 460 are provided on both sides of the upper frame 410. The screen plates 460 are perpendicular to the drive screw 510, so that the sweeping rod 550 pushes the workpiece on the screen 420 to the edge of the screen plate 460 and slides down along the screen plate 460 into the workpiece receiving frame 620. The screen plate 460 is provided with through holes of the same size as the screen holes, so that the abrasive can pass through the through holes and fall into the abrasive receiving frame 610. This allows a small amount of abrasive pushed to the sides by the sweeping rod 550 to also enter the abrasive receiving frame 610, further improving the separation accuracy.

[0029] In one embodiment, such as Figure 4As shown, the drive screw is disposed on one side of the upper frame 410 and is rotatably connected to the upper frame 410. The second drive motor 530 is fixed on the upper frame 410, and the output end of the second drive motor 530 is fixedly connected to the end of the drive screw 510. The guide rod 540 is disposed on the side of the upper frame 410 opposite to the drive screw 510, and the guide rod 540 and the drive screw 510 are on the same horizontal plane. Specifically, the sweeping assembly 500 includes a drive screw 510, a slider 520, a second drive motor 530, a guide rod 540, and a sweeping rod 550. The drive screw 510 and the guide rod 540 are respectively fixed on opposite sides of the upper frame 410, and are arranged in parallel on the same horizontal plane. The second drive motor 530 is fixed on the same side of the upper frame 410 and the drive screw 510, and the output end of the second drive motor 530 is fixedly connected to the end of the drive screw 510. The slider 520 is slidably disposed on the drive screw 510, and one end of the sweeping rod 550 is fixed on the slider 520. In this way, under the action of the second drive motor 530, the slider 520 and the sweeping rod 550 will reciprocate on the drive screw 510, thereby sweeping the workpiece from the surface of the screen 420 to both sides and falling into the workpiece receiving frames 620 on both sides of the screening assembly 400.

[0030] In one embodiment, the sweeping rod 550 is arranged across the screen 420. The first end of the sweeping rod 550 is fixedly connected to the slider 520, and the second end is slidably connected to the guide rod 540. Specifically, to improve sweeping efficiency, one end of the sweeping rod 550 is fixed to the slider 520, and the other end extends to the guide rod 540 and is slidably connected to it. This allows the sweeping rod 550 to span the surface of the screen 420, with its bottom tightly against the screen 420. As the slider 520 moves, the bottom of the sweeping rod 550 scrapes along the surface of the screen 420, effectively pushing the workpiece away and preventing jamming.

[0031] In one embodiment, the receiving assembly 600 includes a drawer-type abrasive receiving frame 610 and a workpiece receiving frame 620. The abrasive receiving frame 610 is disposed below the screen 420 assembly, and the workpiece receiving frame 620 is disposed on both sides of the abrasive receiving frame 610. Both the abrasive receiving frame 610 and the workpiece receiving frame 620 are slidably connected to the housing 300. Specifically, the drawer-type abrasive receiving frame 610 and workpiece receiving frame are located below the screening assembly 400 and are slidably connected to the housing 300. The abrasive receiving frame 610 is located directly below the screening assembly 400, and its width is the same as the distance between the bottoms of the two screen plates 460, so that the abrasive falling from the screen 420 and the screen plate 460 can fall into the abrasive receiving frame 610. There are two workpiece receiving frames 620, which are located on both sides of the abrasive receiving frame 610, so that the workpieces on the screen 420 are pushed to the screen plate 460 and then slide down the screen plate 460 into the workpiece receiving frame 620, ensuring effective separation of the workpieces from the abrasive, improving screening efficiency, and facilitating subsequent processing and recycling.

[0032] In one embodiment, the front end face of the housing 300 is hinged with two doors 330, each with a handle 340 on its front end face. The two doors 330 are symmetrically arranged. Specifically, the hinged portions of the two doors 330 to the housing 300 are located on opposite sides of the front end face of the housing 300. The doors 330 can be opened outwards, and the handles 340 on their front ends facilitate the operation of personnel to open the doors 330 for equipment maintenance and cleaning.

[0033] The general workflow of this utility model is as follows: Open the end cover 210, place the abrasive and the workpiece to be polished into the drum 200, and then close the end cover 210; start the first drive motor 320 to drive the drum 200 to rotate. The drum 200 is equipped with a spiral guide plate 230 to ensure that the abrasive particles are in full contact with the workpiece; after the workpiece is polished, rotate the drum 200 so that the inlet is above the collecting hopper 310, open the end cover 210, and let the workpiece and abrasive enter the box 300 and fall onto the screen 420. Start the vibration motor 450 to make the screen 420 vibrate, so that the abrasive enters the abrasive collection frame 6 below the screen 420 through the mesh. Within 10 seconds, the second drive motor 530 is started, causing the slider 520 to move back and forth along the drive screw 510. The sweeping rod 550 fixed on the slider 520 will move synchronously with the slider 520, thereby pushing the workpiece on the screen 420 into the workpiece collection frames 620 on both sides of the abrasive collection frame 610, thus achieving separate collection of workpiece and abrasive. The abrasive collection frame 610 and the workpiece collection frame 620 are slidably connected. By pulling the handles on the abrasive collection frame 610 and the workpiece collection frame, the abrasive collection frame 610 and the workpiece collection frame can be removed from the box 300, thereby collecting the polished workpiece and allowing the abrasive to be poured into the roller 200 for reuse.
