Description

Technical Field

[0001] This utility model relates to the field of toy burr removal technology, and in particular to a device for removing small burrs from plastic toys. Background Technology

[0002] During the injection molding process of plastic toys, small burrs can easily form on the surface of the toys due to factors such as mold closing gaps and injection pressure fluctuations. These burrs not only affect the smoothness and feel of the plastic toys, but may also cause scratches when children play with them or pose a safety hazard if accidentally ingested. Therefore, burr removal is a key post-processing step in the production of plastic toys.

[0003] However, current technologies for removing fine burrs from plastic toys mainly rely on manual sanding with sandpaper and files or blowing with a regular air gun. Manual sanding is extremely inefficient, especially for the complex fine lines and narrow pores on the toy surface, making it difficult to precisely handle and prone to uneven or over-sanding that can damage the toy's structure. Regular air guns can only remove loose surface burrs and are ineffective at removing firmly attached fine burrs. Furthermore, the burrs tend to scatter and spread during the blowing process, causing dust pollution in the workshop and increasing cleaning costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for removing small burrs from plastic toys.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for removing small burrs from plastic toys includes a workbench and supports at both ends of the top of the workbench. A top frame is fixedly installed on the top of the supports, and a moving component is provided on the top frame. A lifting motor is movably installed on the front side of the top frame through the moving component. A grinding motor is fixedly installed at the output end of the lifting motor, and a grinding head for grinding and removing small burrs on plastic toys is fixedly connected to the output shaft of the grinding motor.

[0007] Below the grinding head is a negative pressure collection hopper for collecting dust and debris generated during grinding. A collection box is fixedly installed on the top of the worktable. The top of the collection box is open, and the bottom of the negative pressure collection hopper is installed on the collection box. An inclined dust filter is fixedly installed inside the collection box. A negative pressure suction head is located on the lower left side of the dust filter. A negative pressure pump is installed on the bottom left side of the collection box, and the output end of the negative pressure pump is connected to the negative pressure suction head. The collection box is also equipped with a vibration component for vibrating and feeding the dust filter.

[0008] Furthermore, the vibration assembly includes an electric telescopic rod fixedly installed on the left side of the collection box. The output end of the electric telescopic rod extends movably into the collection box and is fixedly connected to a sliding pin. The output end of the electric telescopic rod is movably connected to a swing rod via the sliding pin. The other end of the swing rod is fixedly connected to a rubber vibrating head for vibrating and striking the dust filter. A rotating frame is fixedly installed on the left inner wall of the collection box. The middle part of the swing rod is rotatably installed on the rotating frame via a rotating shaft. The swing rod is provided with a movable groove, and the swing rod is slidably connected to the sliding pin via the movable groove.

[0009] Furthermore, a discharge port is provided at the bottom right side of the collection box, and a sealed discharge cover is provided at the discharge port; a buffer pad is provided on the bottom side of the dust filter, and the rubber vibrating head is adapted to the buffer pad.

[0010] Furthermore, the moving component includes a sliding groove on the top frame, a slide block slidably installed in the sliding groove, and the rear side of the lifting motor fixedly installed on the front side of the slide block; a lead screw is rotatably installed in the sliding groove, a lead screw nut is fixedly sleeved on the slide block, and the lead screw and the lead screw nut are threadedly connected; a servo motor is fixedly installed on the left inner wall of the sliding groove, and the servo motor is fixedly connected to the left end of the lead screw.

[0011] Furthermore, a dust cover is provided on the bottom outer side of the grinding motor, and the opening of the dust cover is oriented downwards.

[0012] Furthermore, a controller is provided on the front side of the worktable, and the controller is electrically connected to the lifting motor, the grinding motor and the servo motor respectively.

[0013] The beneficial effects achieved by this utility model using the above structure are as follows:

[0014] 1. In this utility model, the grinding head is rotated by the grinding motor, which can grind and remove small burrs on plastic toys; the position of the grinding head can also be adjusted according to the actual grinding needs, which improves the flexibility of use.

[0015] 2. In this utility model, a negative pressure pump is used in conjunction with a negative pressure suction head to generate negative pressure in the collection box. Under the action of negative pressure, the negative pressure collection bucket is forced to collect the grinding debris and dust downwards into the collection box. At the same time, the inclined dust filter screen can also filter the debris and dust, preventing the debris and dust from penetrating the dust filter screen and causing the negative pressure suction head to become clogged, thus ensuring the normal operation of the negative pressure pump.

[0016] 3. In this utility model, the sliding pin moves left and right by extending and retracting the electric telescopic rod. When the sliding pin moves left and right, it engages with the movable groove on the swing rod, so that the swing rod can swing up and down on the rotating frame through the rotating shaft. When the swing rod swings, it also drives the rubber vibrating head to vibrate and knock on the buffer pad on the bottom side of the dust filter screen, so that the dust filter screen vibrates to prevent debris from accumulating on the upper part of the dust filter screen, which greatly ensures the filtration of the dust filter screen.

[0017] Ultimately, this plastic toy burr removal device, through mechanized operation, avoids the hassle of manual grinding to remove burrs. It not only facilitates the grinding and removal of small burrs on plastic toys, but also quickly collects the debris and dust generated during grinding, preventing the debris and dust from easily splashing and spreading during grinding, thus reducing the difficulty of cleaning. At the same time, it can filter debris and dust to ensure the normal operation of the negative pressure pump, greatly meeting people's needs. Attached Figure Description
