[0029] 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.

[0030] Please see Figure 1-6This utility model provides a technical solution: a burr grinding machine for plastic parts production, including a shell 1, a door 2, a lifting plate 3, a lead screw 4, a fixing block 5, a moving block 6, a connecting plate 7, a cross bar 8, a gear 9, a first belt 10, a rotating shaft 11, a clamping block 12, a grinding roller 13, a second belt 14, a suction fan 15, a partition 16, and a limiting post 17.

[0031] Example 1

[0032] This deburring machine for producing plastic parts is equipped with a clamping and adjusting structure that can clamp both ends of the plastic part and then adjust the height of the plastic part. Specifically:

[0033] A door 2 is rotatably mounted on the front surface of the outer casing 1. A lifting plate 3 is also included, with both ends of the lifting plate 3 slidingly penetrating the inner wall side surface of the outer casing 1. The lifting plate 3 is connected to a clamping adjustment structure, which can clamp plastic parts by controlling the movement of a moving block 6 and a fixed block 5. The clamping adjustment structure includes a lead screw 4, which rotatably penetrates one end of the lifting plate 3. The lower end of the lead screw 4 is rotatably mounted on the lower surface of the interlayer of the outer casing 1. The upper end of the lead screw 4 is fixedly connected to the rotor of a motor, which is mounted on the upper surface of the outer casing 1. A moving block 6 is slidably mounted on the upper surface of the lifting plate 3, and a fixed block 5 is fixedly mounted on the upper surface of the lifting plate 3. A connecting plate 7 is fixedly connected to the lower surface of the moving block 6. The front surface of the connecting plate 7 is provided with a toothed block, which engages with a gear 9. The concentric shaft of the gear 9 is fixedly connected to the rotor of the motor. The motor is installed on the lower surface of the lifting plate 3. The clamping and adjusting structure also includes a cross rod 8. The cross rod 8 is rotatably installed on the inner wall side surface of the lifting plate 3, and one end of the cross rod 8 is connected to the motor. The side surface of the connecting plate 7 is rotatably installed with a connector, which is slidably installed on the outer surface of the cross rod 8. The outer surface of the connector on the side surface of the connecting plate 7 is rotatably installed with a belt 10. The upper end of the belt 10 is connected to a rotating shaft 11, and the rotating shaft 11 rotatably passes through the side surface of the moving block 6. One end of the rotating shaft 11 is equipped with a clamping block 12. The connecting plate 7 is set with an L-shaped structure.

[0034] When using the deburring machine for plastic parts production, such as Figure 1 As shown, first open the front door 2 of the outer casing 1, as follows: Figure 2 As shown, hold the plastic part to be sanded between the fixed block 5 and the movable block 6, as follows. Figure 5 As shown, the motor connected to gear 9 is turned on at this time. Because gear 9 engages with the toothed block on the front surface of connecting plate 7, connecting plate 7 moves. Since a connecting piece is rotatably connected to the side surface of connecting plate 7, and the connecting piece is slidably connected to the cross rod 8, the movement of connecting plate 7 drives the connecting piece to move. Simultaneously, a moving block 6 is connected to the upper surface of connecting plate 7, causing the moving block 6 to move towards the fixed block 5. This allows the fixed block 5 and the moving block 6 to clamp both ends of the plastic part via the clamping block 12 connected by the rotating shaft 11. Figure 4 As shown, the motor connected to the lead screw 4 rotates, causing the lead screw 4 to rotate. Since the lead screw 4 rotates through the lifting plate 3, and the other end of the lifting plate 3 is slidably penetrated by the limiting post 17, the rotation of the lead screw 4 drives the lifting plate 3 to rise, causing the plastic part to be driven to move upward. Then the outer surface of the plastic part contacts the grinding roller 13. Then the motor connected to the cross rod 8 is turned on, causing the cross rod 8 to rotate. The connecting plate 7 is set with an L-shaped structure, so that the cross rod 8 passing through the connecting plate 7 will not affect the tooth block. Then the cross rod 8 drives the belt 10 to rotate through the connecting piece, causing the belt 10 to drive the rotating shaft 11 to rotate. Therefore, the plastic part rotates under the clamping of the clamping block 12.

[0035] Example 2

[0036] This deburring machine for plastic parts production is equipped with a descaling and cleaning structure, which can absorb waste residue while the grinding roller 13 is grinding. Specifically:

[0037] The interior of the outer shell 1 is also provided with a grinding and slag removal structure. The grinding and slag removal structure can make the suction fan 15 absorb the waste residue while the grinding roller 13 rotates. The grinding and slag removal structure includes a grinding roller 13, which is rotatably installed on the inner wall surface of the outer shell 1. One end of the grinding roller 13 is fixedly connected to the rotor of a motor, which is installed on the side surface of the outer shell 1. A second belt 14 is rotatably connected to the outer surface of the concentric shaft of the grinding roller 13, and the other end of the second belt 14 is rotatably connected to the suction fan 15. The suction fan 15 is rotatably installed on the inner wall side surface of the outer shell 1. A cavity 16 is provided in the interlayer of the upper surface of the outer shell 1, and a slot is provided on the lower surface of the cavity 16.

[0038] When the outer surface of the plastic part contacts the grinding roller 13, the door 2 is closed, and the motor connected to the grinding roller 13 is turned on, causing the grinding roller 13 to grind the burrs on the outer surface of the plastic part. Simultaneously, a transparent glass panel is provided on the front surface of the door 2, allowing observation of the grinding process. During grinding, the concentric shaft of the grinding roller 13 drives the belt 14 to rotate. Figure 3 As shown, the rotation of belt 14 drives the suction fan 15 to rotate, so that the suction fan 15 sucks the grinding waste into the cavity 16 through the slot provided on the lower surface of the cavity 16.

[0039] Working principle: When using this plastic part production burr grinding machine, a clamping and adjusting structure is set up to clamp both ends of the plastic part and then drive the plastic part to adjust its height. The grinding and slag removal structure can absorb waste slag while the grinding roller 13 is grinding, which increases the overall practicality.
