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] This utility model provides, for example Figs. 1-4 The device shown is a trimming device for plastic product manufacturing, including a first movable frame 1 and a second movable frame 2. One end of the first movable frame 1 is located inside one end of the second movable frame 2. The ends of the first movable frame 1 and the second movable frame 2 are provided with through holes, and a movable rod 3 is movably arranged in the inner cavity of the through holes. A support plate 4 is fixed on the side of the inner cavity of the first movable frame 1 and the second movable frame 2 away from the movable rod 3. A drive motor 5 is fixed on the outer side of the support plate 4. The output shaft of the drive motor 5 passes through the support plate 4 and is fixed with a rotating shaft 6. An adjustable grinding roller 7 is installed on the outer side of the rotating shaft 6. A support seat 8 is provided on the outer side of the movable rod 3. The end of the rotating shaft 6 away from the drive motor 5 is rotatably connected to the support seat 8 through a bearing. An adjustment component 9 for adjusting the angle of the first movable frame 1 and the second movable frame 2 is provided on the outer side of the movable rod 3.
[0021] The angles of the first movable frame 1 and the second movable frame 2 can be adjusted by adjusting component 9, so that the two sets of grinding rollers 7 fit against the corners of the plastic product. Then, the position of the grinding rollers 7 on the rotating shaft 6 can be adjusted to facilitate fitting different corners. The drive motor 5 drives the rotating shaft 6 to drive the grinding rollers 7, and grinds the protrusions at the corners of the plastic product. It is suitable for plastic products of different shapes and is compact and easy to operate.
[0022] A fixing cylinder 10 is fixed to the inner side of the grinding roller 7. The fixing cylinder 10 is sleeved on the outer side of the rotating shaft 6. A locking screw 11 is threadedly connected to the surface of the fixing cylinder 10 that extends to the outer side of the grinding roller 7. The opposite side of the locking screw 11 extends into the inner cavity of the fixing cylinder 10 and fits against the rotating shaft 6. The fixing cylinder 10 fixed inside the grinding roller 7 is fixed to the rotating shaft 6 by the locking screw 11, which also facilitates the adjustment of the position of the grinding roller 7.
[0023] A sleeve 12 is rotatably connected to the outer side of the movable rod 3 via a bearing. The support seat 8 is fixed to the outer side of the sleeve 12. The sleeve 12 facilitates the support of the support seat 8 and ensures that both sets of rotating shafts 6 are perpendicular to the movable rod 3, so as to facilitate the angle adjustment of the first movable frame 1 and the second movable frame 2.
[0024] The adjusting assembly 9 includes a limiting ring 91 fixed to the outside of the movable rod 3. The limiting ring 91 is located inside the first movable frame 1 and fits against the inner wall of the first movable frame 1. Both ends of the movable rod 3 are threaded and threadedly connected to a locking rotating head 92. The locking rotating head 92 fits against the outside of the second movable frame 2. The limiting ring 91 facilitates support of the first movable frame 1 from the inside, and then the locking rotating head 92 is used from the outside to fit the first movable frame 1 and the second movable frame 2 together, so that the first movable frame 1 and the second movable frame 2 are kept stable by friction.
[0025] The adjusting assembly 9 includes a limiting ring 91 fixed to the outside of the movable rod 3. The limiting ring 91 is located inside the first movable frame 1 and fits against the inner wall of the first movable frame 1. The two ends of the movable rod 3 are threaded and threadedly connected to a locking rotating head 92.

[0026] One side of the grinding roller 7 is flush with one side of the first movable frame 1 and the second movable frame 2 respectively. The contact surfaces of the first movable frame 1 and the second movable frame 2 are set as frosted surfaces. By making the grinding roller 7 flush with the edges of the first movable frame 1 and the second movable frame 2, it is convenient to use the first movable frame 1 and the second movable frame 2 to fit on the outside of the plastic product, ensuring that the edges and corners are ground flat. At the same time, the frosted surface increases the friction between the first movable frame 1 and the second movable frame 2, ensuring the stability between the first movable frame 1 and the second movable frame 2.
[0027] In practical use, the first movable frame 1 and the second movable frame 2 are attached to the corner of the plastic product. Then, the first movable frame 1 and the second movable frame 2 rotate around the movable rod 3. Finally, the first movable frame 1 and the second movable frame 2 are fixed by using the threaded connection between the locking rotating head 92 and the movable rod 3. Then, the position of the grinding roller 7 on the movable shaft is adjusted so that the ends of the grinding roller 7 are attached together. Then, the locking screw 11 is used to lower the rod fixing cylinder 10 and install it on the outside of the rotating shaft 6 so that the grinding roller 7 rotates synchronously with the rotating shaft 6. The drive motor 5 is started, and the drive motor 5 drives the grinding roller 7 to rotate through the rotating shaft 6 to grind the corners of the plastic product.
