[0015] 2. By utilizing the transmission cooperation of the drive motor, drive shaft, drive bevel gear and driven bevel gear, the reciprocating screws on both sides can be driven to rotate synchronously, thereby driving the moving block and moving frame to move back and forth stably, realizing the coordinated linkage of scraping and flushing action of the scraper and flushing pipe; it not only simplifies the overall structure of the device, reduces the manufacturing cost and maintenance difficulty of the equipment, but also ensures the stability and continuity of the cleaning action, improves the waste cleaning efficiency, and ensures that the cleaning operation and deburring processing are carried out simultaneously without affecting the overall production rhythm.

[0016] 3. The collection mechanism enables the classified recycling and treatment of waste materials and wastewater. The inclined dust collection trough guides the waste materials into the collection box through the collection trough, and the metal scraps are intercepted and collected by the filter plate, which facilitates the centralized recycling and reuse of the waste materials. The filtered wastewater flows into the water storage tank. The inclined bottom of the water storage tank guides the wastewater to the discharge outlet, which is convenient for unified discharge or recycling after treatment. This not only avoids environmental pollution caused by the random discharge of waste materials and wastewater, but also realizes the resource recycling of metal waste, which is in line with the concept of green production, and at the same time reduces the environmental protection cost of waste treatment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1-5 The present invention provides the following technical solution: a deburring device for processing metal injection molded products, comprising a device body 1, an operating chamber 101 inside the device body 1, and a door 102 at the feeding end of the operating chamber 101. The operating chamber 101 is provided with a cleaning mechanism for cleaning debris. The cleaning mechanism includes a grid plate 2 fixedly installed at the bottom of the operating chamber 101. A moving groove 103 is opened on the inner wall of the operating chamber 101, and a moving block 301 is slidably installed on the inner wall of the moving groove 103. A moving frame 3 is provided at the end of the moving block 301. A scraper 4 and a flushing pipe 5 are fixedly installed on the inner wall of the moving frame 3. A reciprocating screw 6 is rotatably installed on the inner wall of the moving groove 103, and a driven bevel gear 601 is fixedly installed at the end of the reciprocating screw 6.

[0021] like Figures 2-5 As shown, the grating plate 2 covers the bottom of the operating chamber 101, and the outer wall of the grating plate 2 is provided with through holes distributed in an array. The moving groove 103 is symmetrically opened on both sides of the inner wall of the operating chamber 101, and the length of the moving groove 103 is the same as the width of the operating chamber 101.

[0022] like Figures 2-5As shown, two sets of moving blocks 301 are symmetrically arranged, and the moving frame 3 is located between the two sets of moving blocks 301. The moving frame 3 has an inverted U-shaped cross section. The moving blocks 301 are threadedly connected to the reciprocating screw 6. The bottom outer wall of the scraper 4 is in contact with the outer wall of the grid plate 2. The flushing pipe 5 is symmetrically arranged on both sides of the scraper 4. The outer wall of the flushing pipe 5 is provided with nozzles 501 distributed at equal intervals. The outer wall of the flushing pipe 5 is provided with a water inlet pipe 502, and a water pump is connected to the water inlet pipe 502.

[0023] like Figure 3 and Figure 5 As shown, a drive motor 7 is fixedly installed inside the main body 1 of the device, and a drive shaft 701 is fixedly installed at the output end of the drive motor 7. Two sets of drive bevel gears 702 are symmetrically arranged on the outer wall of the drive shaft 701. The drive shaft 701 is located at the end of the reciprocating lead screw 6, and the drive shaft 701 is perpendicular to the reciprocating lead screw 6. The length of the drive shaft 701 is greater than the length of the two sets of reciprocating lead screws 6. The drive bevel gears 702 are meshed with the driven bevel gears 601.

[0024] When the device performs deburring, the drive motor 7 starts and drives the drive shaft 701 to rotate. The two sets of drive bevel gears 702 on the outer wall of the drive shaft 701 rotate synchronously. Through meshing with the driven bevel gear 601 at the end of the reciprocating screw 6, they drive the reciprocating screws 6 on both sides to rotate synchronously in the moving groove 103. Since the moving block 301 is threadedly connected to the reciprocating screw 6, the rotational motion of the reciprocating screw 6 is converted into the reciprocating linear motion of the moving block 301 along the moving groove 103, which in turn drives the moving frame 3 between the two sets of moving blocks 301 to move synchronously back and forth. During the movement, the scraper 4 on its inner wall, due to its close contact with the surface of the grid plate 2, can scrape off the metal debris accumulated on the grid plate 2 during the operation; at the same time, the flushing pipe 5 connected to the external water pump sprays high-pressure water through the nozzles 501 evenly distributed on the outer wall to flush the fine debris remaining on the surface of the grid plate 2 after being scraped by the scraper 4 and in the through holes, so that the debris falls into the collection mechanism below through the through holes of the grid plate 2; through the synergistic effect of the mechanical scraping by the scraper 4 and the high-pressure water flushing, the waste on the table of the operating room 101 is automatically and comprehensively cleaned.

[0025] Example 2: Please refer to Figures 1-6Based on Embodiment 1, a collection mechanism is also disclosed, the specific structure of which is as follows: The bottom of the main body 1 is provided with a collection mechanism for collecting debris. The collection mechanism includes a dust collection trough 8 and a collection trough 801 located at the bottom of the operating chamber 101. A collection box 9 is slidably installed at the bottom of the main body 1, and a filter plate 901 is provided inside the collection box 9. A water storage tank 802 is provided at the bottom of the collection box 9, and a drain port 803 is provided on the outer wall of the water storage tank 802. The bottom of the dust collection trough 8 is inclined, and the dust collection trough 8 is located at the bottom of the grid plate 2. The top of the dust collection trough 8 is connected to the interior of the operating room 101. The collecting trough 801 is located at the end of the dust collection trough 8, and the cross-section of the collecting trough 801 is Y-shaped. The collecting trough 801 is connected to the dust collection trough 8. The collecting box 9 is located between the collecting trough 801 and the water storage tank 802. The top of the collecting box 9 is connected to the bottom of the collecting trough 801, and the bottom of the collecting box 9 is connected to the water storage tank 802. The bottom of the water storage tank 802 is inclined, and the horizontal plane of the bottom of the water storage tank 802 near the drain 803 is lower than that of the other end.

[0026] Metal scraps and rinsing wastewater processed by the cleaning mechanism fall into the dust collection trough 8 below through the through holes of the grid plate 2. Due to the inclined design of the bottom of the dust collection trough 8, gravity can guide the scraps and wastewater to the end and then into the Y-shaped collection trough 801. The collection trough 801 concentrates the dispersed waste flow and guides it to the collection box 9. The filter plate 901 inside the collection box 9 performs solid-liquid separation on the mixed flow. The metal scraps are intercepted by the filter plate 901 and temporarily stored in the collection box 9 for easy subsequent centralized recycling. The filtered wastewater passes through the filter plate 901 and enters the water storage tank 802 at the bottom. The bottom of the water storage tank 802 is inclined, and the horizontal plane is lower at the end near the discharge port 803, which can guide the wastewater to converge towards the discharge port 803. The staff can discharge the wastewater uniformly through the discharge port 803, or it can be recycled after treatment, thereby completing the classified collection and efficient treatment of processing waste.
