Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 to 3, a winding device of a film laminating machine includes a frame 1 and a winding roller 11. A driving roller 12 is rotatably connected to the frame 1, and the driving roller 12 is driven by a motor (not shown).

The winding roller 11 is connected to the frame 1 through the sliding seat 2 in a sliding manner, so that the winding roller 11 and the driving roller 12 are arranged in parallel and are positioned at the same horizontal height. An air cylinder 21 and a pressure rod 22 are hinged on the frame 1. The cylinder 21 is obliquely arranged, and a power shaft of the cylinder 21 is hinged to the middle of the pressure rod 22. The end of the press rod 22 away from the hinge is abutted against the slide 2. The sliding base 2 slides along the length direction of the frame 1 through a sliding rail.

The cylinder 21 starts, makes depression bar 22 toward the direction removal that is close to slide 2 to make wind-up roll 11 and driving roller 12 support tightly, the sheet is around rolling up on wind-up roll 11 after round driving roller 12, along with the sheet thickness increase of lapping on wind-up roll 11, the distance between wind-up roll 11 and the driving roller 12 increases, slide 2 slowly slides toward the direction of keeping away from driving roller 12, and lie in outermost sheet and driving roller 12 conflict on the wind-up roll 11. The sheet wound on the wind-up roll 11 is made more flat.

A rail 31 is fixed along the width direction of the frame 1, and a support base 32 is slidably connected to the rail 31. The support base 32 may be actuated by a hydraulic cylinder.

The length direction of the track 31 is parallel to the axial direction of the wind-up roll 11. The support base 32 is connected to a cutter 42 via a rotary shaft 41. A transmission mechanism 5 for driving the rotation shaft 41 to rotate is arranged between the support base 32 and the frame 1.

Wherein the transmission mechanism 5 comprises a rack 51 and a toothed ring 52. The ring gear 52 is fixed to the rotary shaft 41, and the ring gear 52 is provided coaxially with the rotary shaft 41. Fixing the rack 51 on the frame 1 and making the rack 51 parallel to the rail 31; the toothed ring 52 is intended to engage with the toothed rack 51.

In order to adapt to sheets of different materials, the rack 51 is rotatably connected to the frame 1 and is connected with the frame 1 through a limiting mechanism 6. The limiting mechanism 6 comprises a mounting hole 61, an elastic piece 62, a limiting concave hole 63 and a limiting block 64. The mounting hole 61 is arranged at the end part of the rack 51; the limiting concave holes 63 are formed in the rack 1, and the two limiting concave holes 63 are distributed along the axis of the rack 51. The end of the limiting block 64 far away from the elastic piece 62 is used for being embedded into the limiting concave hole 63. The two ends of the elastic element 62 are respectively connected with the inner wall of the mounting hole 61 and the limiting block 64.

The elastic member 62 always applies an elastic force to the stopper 64 in a direction approaching the stopper recess 63.

Rotate rack 51, overcome the frictional force between stopper 64 and the spacing shrinkage pool 63, during stopper 64 retreated the mounting hole 61, further rotated and separated with ring gear 52 along with rack 51, when stopper 64 corresponds with another spacing shrinkage pool 63, slided stopper 64 along mounting hole 61 and embedded in this spacing shrinkage pool 63 through the elastic force effect of elastic component 62, realized then that rack 51 fixes a position. Namely, the two limiting concave holes 63 respectively correspond to the two states of meshing and separation of the rack 51 and the toothed ring 52.

In order to improve the protection of the hands of the worker, a positioning mechanism 7 is provided between the cutting blade 42 and the support base 32. The positioning mechanism 7 includes a U-shaped spring 71 and a positioning concave hole 72. Two ends of the U-shaped elastic sheet 71 are fixed on the supporting seat 32; the positioning concave hole 72 is opened in the outer wall of the rotary shaft 41. The middle part of the U-shaped elastic sheet 71 is embedded in a positioning concave hole 72.

In conclusion, when a thin and soft sheet needs to be cut, the rack 51 is rotated to separate the rack 51 from the toothed ring 52, and then the supporting seat 32 is pushed, so that the cutting knife 42 can move in parallel to cut the sheet through the friction force between the U-shaped elastic piece 71 and the positioning concave hole 72, the cutting surface is flat, and the production efficiency is greatly improved. When the need cutting is thicker and the sheet that toughness is stronger, rotate rack 51 once more, make rack 51 and ring gear 52 mesh, promote supporting seat 32, make ring gear 52 drive rotation axis 41 rotatory, rotation axis 41 drives the cutting knife 42 rotatory, overcome the frictional force between U-shaped shell fragment 71 and the location shrinkage pool 72 simultaneously, make cutting knife 42 along with rotatory and the realization of supporting seat 32 translation simultaneously to the sheet cutting.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
