In order to achieve the above purpose, the utility model discloses technical scheme as follows:
the burr-free processing structure of the glue film product comprises a punching block cutter set for relatively punching a material belt to an adjacent broken state and a boss assembly for relatively pushing out waste materials in the adjacent broken state material belt; the punching block knife tackle includes annular knife face, locates the sword front on the inner ring of knife face, the sword front corresponds the critical waste discharge area to the material area that cuts off, knife face protrusion in the surface of etching panel, boss subassembly include with knife face inner ring size corresponding boss, locate boss surface's elastic component, the elastic component releases the waste discharge area.
Specifically, the back surface of the etching panel is provided with a pressing plate, the pressing plate is provided with a plurality of vertical positioning columns penetrating through the etching panel, and the positioning columns and the boss assemblies are arranged on the same surface.
Specifically, the size of the elastic piece is consistent with that of the surface of the boss.
Specifically, the material belt is arranged on the surface of the avoiding plate, and a waste material groove corresponding to the boss is formed in the avoiding plate.
Specifically, a positioning hole corresponding to the positioning column is formed in the avoiding plate.
Specifically, be equipped with the annular portion that a plurality of equidistance intervals set up on the material area, the interior week of annular portion is for waiting to waste discharge area.
Compared with the prior art, the utility model discloses glue type membrane product burr-free processing structure's beneficial effect mainly embodies:
the etching panel is arranged in the pressing plate, and is positioned by the positioning column, and CNC is formed at one time, so that the accuracy of the etching panel and the pressing plate is ensured; the edge of a knife mouth cuts off the inner periphery of the annular part to a critical state, waste materials are not removed and transferred to the lower side of the boss, the positioning column is automatically abutted to the positioning hole, the boss is aligned with the waste discharge area, in the process of repeated punching, the boss and foam release the waste materials to the waste material groove, the extrusion problem of the traditional cutter is avoided, the waste discharge problem is solved, and the processing efficiency is improved.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments, but not all embodiments of the present invention.
Example (b):
referring to fig. 1-3, the present embodiment is a burr-free processing structure for a plastic film product, including a punch block cutter set for relatively punching a material strip to a temporary broken state, and a boss assembly for relatively pushing out waste material in the temporary broken state material strip 1.
On etching panel 2 was all located to die block knife tackle and boss subassembly, the back mounted of etching panel 2 had clamp plate 21, was equipped with a plurality of vertical reference columns 22 that run through etching panel 2 on the clamp plate 21, and reference column 22 sets up with the boss subassembly coplanar.
The punching block knife group comprises an annular knife face 3 and a knife edge 31 arranged on the inner ring of the knife face 3. The rake face 3 protrudes from the surface of the etched panel 2.
The boss assembly comprises a boss 4 corresponding to the inner ring size of the knife face 3 and an elastic piece (not marked in the figure) arranged on the surface of the boss 4. In this embodiment, the elastic member is foam. The dimensions of the elastic element correspond to the dimensions of the surface of the boss 4.
The material belt 1 is arranged on the surface of the avoiding plate 5, and a waste material groove (not shown in the figure) corresponding to the position of the boss 4 is arranged on the avoiding plate 5. The avoidance plate 5 is provided with a positioning hole corresponding to the positioning column 22. The material belt 1 is provided with a plurality of annular parts 11 which are arranged at equal intervals, and the inner periphery of the annular parts 11 is an area 12 to be discharged.
When using this embodiment, etch panel 2 aligns with material area 1 and pushes down, and knife face 3 and the corresponding laminating of annular portion 11, the interior week of the die-cut annular portion 11 of blade edge mouth 31 to the state of facing absolutely, material area 1 moves to boss subassembly below along dodging board 5, and the cotton pushing down of bubble pushes out waste material in the annular portion 11 to the waste material inslot.
