[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0028] like Figure 1-3As shown, the utility model provides an edge binding mechanism, including: a conforming pleating block 110, a guide mechanism 120, a guide column 121, a linear bearing 122, a conforming edge pushing block 130, a limiting mechanism 140, a limiting unloading bolt 141, and a spring 142.

[0029] like Figure 1 As shown, the conformable pleating block 110 is arranged at the bottom of the edging mechanism, and at least three guide mechanisms 120 are arranged on the conformable pleating block 110. The conformable edge pushing block 130 is located above the conformable pleating block 110, one end of the guide mechanism 120 is arranged in the conformable pleating block 110, and the other end is arranged in the conformable edge pushing block 130; one end of the limiting mechanism 140 passes through the conformable edge pushing block 130 and the conformable pleating block 110 in sequence, and the conformable pleating block 110 can move axially along the guide mechanism 120 and be reset and limited by the limiting mechanism 140.

[0030] A first connecting hole and a second connecting hole are respectively provided on the conformable pleating block 110 and the conformable edge pushing block 120. One end of the guide mechanism 120 is arranged in the first connecting hole, and the other end is arranged in the second connecting hole. In the utility model, as a preferred embodiment, the number of the guide mechanisms 120 is three, and therefore, the number of the first connecting hole and the second connecting hole are also three respectively.

[0031] One end of the conformable pleating block 110 is arc-shaped and extends upward to form an extension portion. The conformable edge pushing block 130 is located above the conformable pleating block 110 and on one side of the extension portion. One end of the conformable edge pushing block 130 is arc-shaped and has a clearance fit with the extension portion of the conformable pleating block 110, and the clearance is 0.1 mm.

[0032] like Figure 2 As shown, the guide mechanism 120 includes: a guide column 121 and a linear bearing 122. The linear bearing 122 is arranged in the first hole and has an interference fit with the first hole. One end of the guide column 121 is matched and arranged in the linear bearing 122, and the other end is arranged in the second connecting hole. The conformable pleat block 110 can move axially along the guide column 121.

[0033] like Figure 3 As shown, the limiting mechanism 140 includes: a limiting unloading bolt 141 and a spring 142. One end of the limiting unloading bolt 141 passes through the conformal push block 130 and the conformal pleating block 110 in sequence. The spring 142 is coaxially arranged on the outside of the limiting unloading bolt 141 and is located between the conformal push block 130 and the conformal pleating block 110, and is used to reset the conformal pleating block 110. The other end of the limiting unloading bolt 141 is arranged on the top of the conformal push block 130. The other end of the limiting unloading bolt 141 is a nut structure with a diameter larger than the diameter of one end of the limiting unloading bolt 141, and is used for limiting.

[0034] In the present invention, as a preferred embodiment, the material of the free-standing pleating block 110 and the free-standing edge pushing block 130 are both 7075 aluminum.

[0035] When working, six integrated edge wrapping mechanisms are required to cooperate, which are located in the circumference of the product to be wrapped. The six integrated edge wrapping mechanisms work simultaneously. After the conforming edge pusher block 130 flips the edge skin of the product inward, the conforming pleating block 110 moves upward to bond the flipped skin to the inner wall of the product to maintain pressure. Among them, this mechanism can realize the pressing action after flipping. In the utility model, as a preferred embodiment, the linear bearing 122 uses a high-precision bearing to ensure that the shaking deviation is reduced when moving up and down, and to ensure the clearance between the conforming edge pusher block 130 and the conforming pleating block 110. The edge wrapping mechanism provided by the utility model realizes the consistency of the edge wrapping of the laminating mold, is easy to debug, reduces the debugging samples, prolongs the service life, and ensures the edge wrapping effect.

[0036] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
