Problems solved by technology

[0004] Winding, fixed length and cutting are usually completed by two equipments, which occupy a large area and are inconvenient to operate, and the traditional cutting machine has a complicated structure and high cost
In addition, after the film is wound by the winding machine for one turn, its film length is a fixed value, and the adjustment of the film length is limited to the change of multiples, and the adjustment flexibility of the film length is poor.

Embodiment 1

[0031] Such as Figure 1-2 As shown, the present embodiment includes a feeding device, a deceleration mechanism, a fixed-length winding device, and a driving device. The feeding device is arranged in front of the fixed-length winding device for feeding the film 7 to the fixed-length winding device, and the output of the driving device is connected to the fixed-length winding device.

[0032] The feeding device includes a long shaft and a feeding cylinder 12. The long shaft includes a first shaft body 111, a second shaft body 112, a third shaft body 113, and a fourth shaft body 114 from the end to the middle area. The first shaft body 111 is the same as the outer diameter of the third shaft body 113 and is larger than the outer diameter of the second shaft body 112 and smaller than the outer diameter of the fourth shaft body 114; the feeding cylinder 12 is sleeved on the fourth shaft body 114, and the feeding cylinder 12 is provided with bolt 10 mounting holes.

[0033] Such ...

Embodiment 2

[0053] Such as Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that the support rod 42 is provided with external threads, and the two ends of the cross bar 43 are sleeved on the corresponding support rods 42 respectively. Both upper and lower sides are provided with first nuts 47 , and the first nuts 47 are screwed on the corresponding support rods 42 .

[0054] The position of the cross bar 43 is adjusted by turning the first nut 47 .

Embodiment 3

[0056] Such as Figure 9 As shown, the difference between this embodiment and Embodiment 1 is that the lower end of the support rod 42 is provided with a positioning block 410, the positioning block 410 is provided with a spring sleeve 49, the upper end of the support rod 42 is spun with a second nut 48, and the cross bar The two ends of 43 are sleeved on the corresponding support rod 42 and located between the corresponding spring sleeve 49 and the second nut 48 .

[0057] By rotating the second nut 48 and compressing the spring sleeve 49, the position of the cross bar 43 is adjusted.

Abstract

The invention discloses a fixed-length film cutting machine. The fixed-length film cutting machine comprises a feeding device, a fixed-length winding device and a driving device, wherein the feeding device is arranged in front of the fixed-length winding device and is used for feeding a thin film to the fixed-length winding device; the driving device is in outputting connection to the fixed-length winding device; and a film cutting structure is arranged on the fixed-length winding device. The fixed-length film cutting machine has the advantages of simple structure and good flexibility on adjustment of lengths of films.

Description

technical field [0001] The invention relates to the field of film technology, in particular to a fixed-length film cutting machine. Background technique [0002] A film is a thin, soft, transparent sheet. Made of plastic, adhesive, rubber or other materials. The scientific explanation of polyester film is: a two-dimensional material formed by depositing atoms, molecules or ions on the surface of a substrate. Example: optical film, composite film, superconducting film, polyester film, nylon film, plastic film, etc. Films are widely used in electronics, machinery, printing and other industries. [0003] The production process of the film bag includes the following steps: (1) pass the resin masterbatch through the blown film machine; (2) use the winding machine to wind up and cut out the set length by the cutting machine; (3) use the heat sealing machine Heat sealing; (4) Cutting out a film bag with heat sealing at the bottom, sealing at both sides, and opening at the top. ...
