[0017] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Depend on Figures 1 to 6 It can be seen that a plastic winding tube trimming device includes a main body 1, a rotating shaft 2 is rotatably provided inside the main body 1, a plurality of gear rings 3 are coaxially provided on the outside of the rotating shaft 2, a plurality of support plates 4 are telescopically provided on the side of the main body 1 and mesh with the gear rings 3 one by one, the ends of the plurality of support plates 4 are in contact with the inner wall of the winding tube to form a structure in which the center of the rotating shaft 2 is coaxial with the center of the winding tube, a trimming mechanism is provided at the end of the main body 1 which is concentric with the rotating shaft 2, and the trimming mechanism includes a plurality of trimming blocks 5, which cooperate with the end of the winding tube, and the trimming mechanism rotates to complete the trimming processing of the winding tube.

[0019] When the utility model is used,

[0020] Insert the main body 1 into the winding tube, rotate the rotating shaft 2, extend the support plate 4 outward, make the end of the support plate 4 contact the inner wall of the winding tube, make the center of the rotating shaft 2 coincide with the center of the winding tube, fit the trimming block 5 with the edge of the winding tube, start the trimming mechanism, and the trimming mechanism rotates to drive the trimming block 5 to trim the edge of the winding tube.

[0021] A first motor 6 is fixed to the side of the main body 1 , and the end of the rotating shaft 2 is engaged with the first motor 6 via a gear set. The first motor 6 drives the rotating shaft 2 to rotate inside the main body 1 , driving the extension and retraction of the support plate 4 .

[0022] A rack 7 meshing with the gear ring 3 is provided on the support plate 4 , and the rack 7 meshes with the gear ring 3 to realize transmission between the rotating shaft 2 and the support plate 4 .

[0023] A support block 8 is provided at the end of the support plate 4. The outer end of the support block 8 is arc-shaped. The arc-shaped support block 8 has a smaller contact point when in contact with the inner wall of the winding tube, so that the coincidence degree between the rotating shaft 2 and the center of the winding tube is higher, and the position during trimming is more accurate.

[0024] A second motor 9 is fixed to the end of the main body 1, and the second motor 9 drives the trimming mechanism. The trimming mechanism includes a fixed plate 10 fixedly connected to the second motor 9, and a plurality of extension plates 11 extend from the outside of the fixed plate 10. A slide groove 12 is provided inside the extension plate 11 and an adjusting screw 13 is provided. A slider 14 is slidingly provided inside the extension plate 11, and the slider 14 is threadedly connected to the adjusting screw 13. The trimming block 5 is arranged at the bottom of the slider 14.

[0025] Before trimming, move the trimming block 5 and make the trimming block 5 correspond to the edge of the winding tube. Due to the action of the adjusting screw 13, the position of the slider 14 is stable and no displacement occurs during the trimming process, ensuring the contact between the trimming block 5 and the edge of the winding tube. The second motor 9 rotates to drive the trimming block 5 to rotate, thereby trimming the edge of the winding tube.

[0026] Compared with the prior art, the utility model has the following beneficial effects: the trimming mechanism is set as a movable small structure, which can be directly placed on the end of the winding tube for use, occupies a small area, and can be flexibly applied to winding tubes of various specifications, and is easy to use.
