DETAILED DESCRIPTION
[0017] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The schematic implementation scheme of the present invention and its description are only used to analyze the present invention and are not intended to limit the present invention.
[0018] Figures 1-8 The specific structure of a film sheet forming device in one embodiment of the present invention is shown. The film sheet forming device includes a die-cutting section 1 and a finished product waste separation section 2. The die-cutting section 1 includes a die-cutting power unit 11 mounted on a machine base 3, an adjustment power unit 12, and an upper die base 13 and a lower die base 14 that cooperate with each other. The upper die base 13 is equipped with a die-cutting tool. The upper die base 13 is connected to the die-cutting power unit 1 and is connected to the machine base 3 through the die-cutting power unit 1. The lower die base 14 includes an upper wedge block 14 that is spliced together along an inclined surface. 1. Lower wedge block 142. The lower wedge block 142 is provided with a plurality of radially penetrating adjustment long holes 1421. The machine base 3 is provided with a plurality of penetrating mounting holes. The mounting holes are all provided with mounting sleeves 31. The connecting rod 1411 at the bottom of the upper wedge block 141 moves downward in sequence through the adjustment long holes 1421 and the mounting sleeves 31, and extends to the bottom of the machine base 3. The adjustment power device 12 is provided on one side of the lower die base 14 and is connected to the lower wedge block 142 to drive the lower wedge block 142 to move horizontally.
[0019] The present invention provides a film sheet forming device, wherein the lower die base 14 of the die-cutting portion 1 is designed to be a structure composed of the upper wedge block 141 and the lower wedge block 142 spliced together along the inclined surface, and the lower wedge block 142 is connected to the adjustment power device 12, and a plurality of adjustment long holes 1421 are provided on the lower wedge block 142, and a plurality of corresponding adjustment long holes 1421 are provided on the base 3. The mounting hole is provided with the mounting sleeve 31, so that the connecting rod 1411 at the bottom of the upper wedge block 141 can move downward through the adjusting long hole 1421 and the mounting sleeve 31 in sequence, and extend out of the bottom of the base 3, thereby movably connecting the upper wedge block 141 with the lower wedge block 142 and the base 3, and the upper wedge block 141 is pressed against the inclined surface of the lower wedge block 142 under the action of gravity. When the adjusting power device 12 drives the lower wedge block 142 to move horizontally relative to the machine base 3 and the upper wedge block 141, the connecting rod 1411 of the upper wedge block 141 is restricted by the mounting sleeve 31 in the horizontal direction and cannot move horizontally with the lower wedge block 142. In the vertical direction, the upper wedge block 141 is pressed against the inclined surface of the lower wedge block 142 under the action of gravity. , and slowly moves up and down along the inclined surface of the lower wedge block 142. The characteristic of this adjustment method is that the vertical movement distance and speed of the upper wedge block 141 are always smaller than the horizontal movement distance and speed of the lower wedge block 142. Therefore, the lower wedge block 142 can be controlled to move slowly horizontally by the adjustment power device 12, thereby controlling the slight movement of the upper wedge block 141 in the vertical direction, thereby achieving fine adjustment of the distance between the upper and lower mold bases.
[0020] Furthermore, in this embodiment, Figure 6 As shown, the lower end of the connecting rod 1411 is movably sleeved with a limit nut 41 , and the connecting rod 1411 is also sheathed with a first buffer spring 42 , which is located between the bottom of the base 3 and the limit nut 41 .

A mounting protrusion 33 is connected to the outside of the base 3, and the mounting protrusion is provided with a through hole 331. The screw passes through the through hole 331 and is connected to the connecting screw hole 21311 to lock the first driven roller 213. When the screw is separated from the connecting screw hole 21311, the first driven roller 213 is in a free state and can be moved up and down along the adjusting slot 32 to adjust the tension of the first belt 214.
[0026] Furthermore, in this embodiment, Figure 1 、 Figure 4 and Figure 5 As shown, the finished waste material separation part 2 also includes a separation auxiliary component, which includes a mounting frame 23 and a plurality of auxiliary rubber block adjustment seats 24.
