Description

Technical Field

[0001] The utility model relates to the technical field of slicers, in particular to a thin film slicer used for producing protective films. Background Art

[0002] Plastic protective film is usually made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins. It has the characteristics of colorless, transparent, moisture-resistant, airtight, soft and strong. It is often used for packaging and coating layers and is widely used in food, medicine, chemical industry and other fields. The film slicer for protective film production described in Publication No. CN212601989U places the film ring to be cut on the roller, pulls one end of the film onto the cut-resistant belt, and passes through the lower end of the rotating pressure roller. The active roller is driven to rotate by providing a rotating motor and a rotating motor, and the driven roller is driven to rotate by the cut-resistant belt, thereby driving the film pressed on the cut-resistant belt to move forward. The rotating motor can drive the slider to move back and forth in the slide groove through the first connecting rod and the second connecting rod to slice the film. However, the prior art still has the following defects:

[0003] 1. In the prior art, rollers, active rollers and driven rollers are arranged in the installation box, and the rollers, active rollers and driven rollers are all rotatably connected with the installation box. The active rollers and driven rollers are provided with cut-resistant belts to transport the film. However, in actual use, different types of films have different tensions and are often wound on rolls of different sizes. The size of the rollers in the prior art cannot be adjusted, and the rolls used for different types of films cannot be well fixed.

[0004] 2. In the prior art, a cut-resistant belt is provided on the active roller and the driven roller, and a small mounting frame is provided above the mounting box. A rotating pressure roller is provided on the small mounting frame. The rotating pressure roller contacts the cut-resistant belt to facilitate the transportation of the film. However, the fixing effect of the film by only one rotating pressure roller is general, and there is a risk of the film shifting and falling. Utility Model Content

The inner wall of the fixing ring 62 is rotatably connected to the sleeve 61, and a plurality of connecting rods 63 are rotatably connected to the outer wall of the fixing ring 62. The end of the connecting rod 63 away from the fixing ring 62 is rotatably connected to the opposite side of the two baffles 53, so that the connecting rod 63 drives the top plate 54 to move.

[0023] A storage table 7 is fixedly connected to the upper end of the bottom plate 1 for convenient placement of the film to be cut. The upper ends of both sides of the storage table 7 are arc-shaped to prevent leaving marks on the film. An inverted U-shaped fixing frame 8 is arranged above the storage table 7. A conveying mechanism 10 is fixedly connected inside the fixing frame 8 to facilitate the control of the movement of the film. The conveying mechanism 10 includes two shafts 101, which are rotatably connected to the front and rear inner walls of the fixing frame 8. A roller 102 is sleeved on the shaft 101, and the roller 102 is fixedly connected to the side wall of the shaft 101. A conveyor belt 103 for connection is wound between the two rollers 102, and the conveyor belt 103 is movably connected to the film. A conveying motor 104 is fixedly connected to one end of the outer wall of the fixing frame 8, and the output end of the conveying motor 104 passes through the fixing frame 8 and is rotatably connected to it. The output end of the conveying motor 104 is also fixedly connected to the shaft 101 on one side, which is convenient for controlling the movement of the conveyor belt 103.

[0024] In order to control the movement of the fixed frame 8 so that the conveyor belt 103 can press and limit various films on the upper side of the storage table 7, an adjusting mechanism 9 is fixedly connected in the middle of the upper end of the bottom plate 1, and the adjusting mechanism 9 includes an inverted U-shaped bracket 91, and the bottom end of the bracket 91 is fixedly connected to the bottom plate 1, and a double-headed screw 92 is rotatably connected to the upper end of the inner wall of the bracket 91, and two sliders 93 are sleeved on the double-headed screw 92. The two sliders 93 have opposite threads inside, which cooperate with the two threads on the double-headed screw 92 so that the two sliders 93 can move in the same direction or in the opposite direction along the double-headed screw 92, and connecting rods 3 94 are rotatably connected on both sides of the sliders 93, and the bottom end of the connecting rod 3 94 is rotatably connected to the fixed frame 8, and an adjusting motor 95 is fixedly connected to the upper end of the front outer wall of the bracket 91, and the output end of the adjusting motor 95 passes through the bracket 91 and is fixedly connected to the front end of the double-headed screw 92.

[0025] In order to achieve the cutting of the film so that its size meets the use requirements, a cutting mechanism 11 is fixedly connected to the other side of the upper end of the base plate 1, and the cutting mechanism 11 includes a bracket 111. The bottom end of the bracket 111 is fixedly connected to the base plate 1, and the upper outer wall of the bracket 111 is provided with a cylinder 112 passing through it.

[0026] During the specific implementation of the present invention, the material roll with the film to be cut is first sleeved on the upper end of the top plate 54, and then the shaft sleeve 61 is rotated to make it move along the fixed column 4, thereby driving the fixed ring 62 to move, so that the second connecting rod 63 is driven to rotate. At this time, the baffle 53 will be driven by the second connecting rod 63 and gradually approach the inner wall of the material roll. After the top plate 54 is fitted and fixed to the inner wall of the material roll, the rotation of the shaft sleeve 61 is stopped, and then one end of the film on the material roll is pulled out and placed on the upper end of the storage table 7, and then the adjustment motor 95 is started to drive the double-headed screw 92 to move, so that the two sliders 93 start to run along the double-headed screw 92, and the fixed frame 8 is driven to the storage table through the third connecting rod 94. 7, the film on the upper side approaches, and after the conveyor belt 103 is in close contact with the film, the fixed motor 55 and the transport motor 104 are started, so that the fixed motor 55 drives the fixed column 4 to rotate, and the transport motor 104 drives the shaft 101 on one side to rotate, thereby driving the roller 102 on one side to rotate. Under the action of the conveyor belt 103, the roller 102 on the other side will also be driven to move, so that the conveyor belt 103 drives the film to move to one side. After the film moves to the bottom of the cutter 113, the cylinder 112 is started to push the cutter 113 to move along the guide column 114 to cut the film. After cutting, the cut film is stored, and the use process of the device is completed.

[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
