DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 5 As shown, a plastic product trimming device includes a base plate 1, which is supported by a support leg 101 installed on the bottom surface, and a workbench 2 located on the upper surface of the base plate 1 rotates inside the base plate 1 through a rotating member 201 on the bottom surface, and a limiting hole 203 opened on the bottom surface of the rotating member 201 cooperates with a limiting component 3 for limiting, and a straight groove 204 is opened on the surface of the workbench 2 to facilitate the clamping component 4 to move and clamp, and the clamping component 4 is provided with a screw 401 controlled by a knob 402, so that the adjusting plate 404 rotatably connected to the other end of the screw 401 can pass through a clamping block 405 sliding on the surface, and is fitted with a non-slip pad 406 on the surface for non-slip clamping, and on the other side of the clamping block 405 A spring 2 407 is provided on the surface to provide elastic support for the clamping block 405. The grinding knife 5 located on one side of the clamping assembly 4 is driven by the driving motor 502 through the inner driving rod 501, so that the grinding knife 5 can rotate at high speed for grinding and trimming. The threaded part 503 fixed on the upper end of the driving rod 501 is threadedly connected with the nut 504 to limit the grinding knife 5. The adjustment assembly 6 located below the grinding knife 5 is provided with a slide bar 601, which pushes the slider 602 at one end to drive the driving motor 502 on the upper surface to move, and the short screw 603 above the slide bar 601 can be threadedly connected to the inner side of the base plate 1, so that the limiting plate 604 fixed at the bottom end limits the slide bar 601.

[0036] A plurality of balls 202 are provided on the peripheral surface of the rotating member 201 and are attached to the inner side of the bottom plate 1 .

[0037] Through the above technical solution, the rolling of the ball 202 reduces the friction between the rotating member 201 and the base plate 1 when the rotating member 201 drives the workbench 2 to rotate, thereby making the rotation smoother.

[0038] The limiting component 3 is provided with a button 301 slidably connected to the surface of the base plate 1, so that the button 301 can push the U-shaped connecting rod 302 on the ground to move downward, so that the block 303 at the other end can be engaged with the inner side of the limiting hole 203, and the spring 1 304 on the bottom surface of the connecting rod 302 provides elastic support for it.

[0039] Through the above technical solution, under the elastic support of spring 1 304, when there is no external force pressing the button 301, the connecting rod 302 can push the block 303 to be engaged with the inner side of the limiting hole 203 to limit the rotating member 201.

[0040] The threaded ring 403 threadedly connected to the surface of the screw 401 is fixed to one side of the upper surface of the workbench 2 .

[0041] Through the above technical solution, under the limitation of the threaded ring 403, the screw 401 can push the adjustment plate 404 to move when rotating, so that the clamping block 405 on the surface of the adjustment plate 404 is used for clamping.

[0042] The clamping strip 505 fixed on the inner side of the grinding knife 5 is clamped on the surface of the driving rod 501 .

[0043] With the above technical solution, the clamping of the clamping strip 505 allows the rotation of the driving rod 501 to smoothly drive the grinding knife 5 to rotate together, thereby ensuring that the grinding knife 5 can rotate at high speed for grinding.

[0044] During use, when the user uses the plastic product trimming device, the plastic product to be trimmed is placed on the surface of the workbench 2, and the screw 401 is rotated by the knob 402. Under the connection of the threaded ring 403, the adjustment plate 404 can slide inside the straight groove 204 and approach the plastic product, so that the clamping block 405 connected to the inner side of the adjustment plate 404 by the spring 2 407 can be extended and retracted according to the different shapes of the plastic product, and the anti-slip pad 406 is used to fit the surface of the plastic product to limit it. Then, the short screw 603 is rotated to make the limiting plate 604 away from the slide rod 601, so that the slide rod 601 can drive the slider 602 to move, so that the slider 602 can adjust the upper grinding knife 5, adjust it to fit the plastic product, and then use the limiting plate 604 to limit the sliding rod 601, start the driving motor 502, and drive the grinding knife 5 to rotate under the limit of the clamping bar 505 through the driving rod 501 to trim the plastic product. In the process of trimming, press the button 301 downward at any time. Under the elastic force of the spring 1 304, the clamping block 303 is disengaged from the limiting hole 203, so that the workbench 2 can be rotated through the cooperation of the rotating part 201 and the ball 202 to adjust the trimming position of the plastic product. At the same time, when the grinding knife 5 needs to be replaced later, the nut 504 is removed from the surface of the threaded part 503, and the grinding knife 5 is slid upward to remove it for replacement.

[0045] The knob 402 and the short screw 603 are provided with a latch structure with a locking function.

[0046] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of this disclosure omits the detailed description of known functions and known components.
