Description

Technical Field

[0001] This utility model relates to the field of high-barrier film high-speed slitting machine technology, and in particular to an edge suction device for a high-barrier film high-speed slitting machine. Background Technology

[0002] In roll-to-roll slitting equipment, wide substrates (1m-2.5m), such as PET, PP, PE, PA, or functional films made from these substrates (e.g., high-barrier films), are typically slit into narrower widths (200mm-2000mm) as required by the customer. During slitting, the slit film material needs to be wound onto a core. Core diameters are typically 3 inches, 6 inches, 8 inches, or 10 inches, and the material is generally paper core or PVC, PE, PP, ABS, or fiberglass tubing. Due to the processing technology, both ends of wide substrates or functional films usually have a certain width of ineffective or unstable areas, also known as process edges, which need to be cut off. Typical process edges are 5mm-50mm. These process edges also usually require winding with a core during slitting. After the process edge is wound up, it has no use value. The process edge film material and the core are eventually disposed of as waste. Because the process edge film material is relatively narrow, if it is slit and wound at high speed, it is very easy to slip or break the film. The slitting production process has to be interrupted and film splicing is carried out, which seriously affects the stability of slitting. Utility Model Content

[0020] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of protection of this utility model.

[0021] Please see Figures 1 to 4 An edge suction device for a high-barrier film high-speed slitting machine includes two edge suction flat tubes 10, two edge feeding guide tubes 20, a Y-shaped tee tube 30, a B-shaped tee tube 40, an edge suction fan 50, and an edge material collection unit 60. The two edge suction flat tubes 10 are arranged opposite each other at the output end of the high-barrier film high-speed slitting machine. One end of each edge suction flat tube 10 corresponds to the output position of a slitting film edge, and this end is a rectangle parallel to the film edge laterally and has an input port. The other end of the edge suction flat tube 10 extends outward, and this end is cylindrical and has an output port. One end of each edge feeding guide tube 20 is connected to the output port of an edge suction flat tube 10.

[0022] The Y-shaped tee pipe 30 has a converging cavity 31 at one end and two connecting pipe ports 32 communicating with the converging cavity 31 at the other end. Each connecting pipe port 32 is connected to the other end of a side-feeding conduit 20.

[0023] The 1 / 2-shaped tee pipe 40 has a first connector 41 and a second connector 42 connected in a straight line, and a third connector 43 inclined towards the first connector 41 and connected between the first connector 41 and the second connector 42. The third connector 43 is connected to the converging cavity 31 of the Y-shaped tee pipe 30. The first connector 41 is connected to the air outlet of the edge suction fan 50, and the second connector 42 is connected to the edge material collection unit 60. The edge suction fan 50 blows air into the 1 / 2-shaped tee pipe 40. The airflow is introduced into the edge material collection unit 60 along the first connector 41 and the second connector 42, so that the converging cavity 31 forms a negative pressure. Thus, the slit film edge can be sucked in by the two edge suction flat pipes 10, and the film edge is transported to the edge material collection unit 60 along the two edge delivery guide pipes 20, the Y-shaped tee pipe 30 and the third connector 43 and the second connector 42 of the 1 / 2-shaped tee pipe 40.

[0024] Furthermore, in this embodiment, the converging cavity 31 is in the shape of a trumpet that gradually expands toward the third connecting head 43. The third connecting head 43 has an adsorption cavity 431 at one end that communicates with the converging cavity 31. The adsorption cavity 431 is in the shape of a trumpet that gradually expands toward the converging cavity 31. By communicating with the adsorption cavity 431 through the converging cavity 31, it is easier to generate a greater adsorption force.

[0025] Furthermore, in this embodiment, the diameter of the end of the first connector 41, the second connector 42, and the third connector 43 that are connected to each other is 8 cm.

[0026] Furthermore, in this embodiment, the end of the first connecting pipe 41 connected to the edge suction fan 50 is shaped like a trumpet, gradually expanding towards the air outlet of the edge suction fan 50; the end of the second connecting pipe 42 connected to the edge material collection unit 60 is shaped like a trumpet, gradually expanding towards the edge material collection unit 60, and the pipe diameter of the end of the first connecting pipe 41 connected to the edge suction fan 50 is larger than the pipe diameter of the other end; the pipe diameter of the end of the second connecting pipe 42 connected to the edge material collection unit 60 is larger than the pipe diameter of the other end; the pipe diameter of the end of the third connecting pipe 43 connected to the converging cavity 31 is larger than the pipe diameter of the other end, with a pipe diameter ratio of 1.2 to 1.5:1, so that the converging cavity 31 can form a larger negative pressure and generate a larger suction force.

[0027] Furthermore, in this embodiment, the output end of the high-barrier film high-speed slitting machine is provided with a slide bar for mounting two suction flat tubes 10. Each suction flat tube 10 is fixed to the slide bar by a movable clamp and moves in a direction parallel to the winding shaft, which is convenient for adjustment according to the slitting position.

[0028] Furthermore, the edge-feeding conduit 20 is made of stainless steel or plastic tubing with a smooth inner wall to prevent membrane edge residue from remaining on the tube wall; in this embodiment, the edge-feeding conduit 20 is preferably a transparent plastic tubing.

[0029] Furthermore, in this embodiment, the diameter of the edge delivery guide tube 20 is 6-10 cm, which facilitates the delivery of the membrane edge.

[0030] Furthermore, in this embodiment, the edge material collection unit 60 adopts a collection box with a hollow structure and has a door that can be opened and closed on its side or multiple sides. The hollow structure allows airflow to pass through without obstruction, while the door can be used to conveniently remove the film edge.

[0031] Understandably, the method of using the edge suction device of the high-barrier film high-speed slitting machine of this utility model is as follows: Adjust the installation position of the two edge suction flat tubes 10 on the slide rod so that each edge suction flat tube 10 corresponds to the output position of a slitting film edge; then, while the high-barrier film high-speed slitting machine is cutting the film, start the edge suction fan 50 so that the edge suction fan 50 blows air into the U-shaped three-way pipe 40. The airflow is introduced into the edge material collection unit 60 along the first connecting pipe 41 and the second connecting pipe 42. The converging chamber 31 forms a negative pressure, and the two edge suction flat tubes 10 suck in the slitting film edge. The film edge is then transported to the edge material collection unit 60 along the two edge delivery guide tubes 20, the U-shaped three-way pipe 30, and the third connecting pipe 43 and the second connecting pipe 42 of the U-shaped three-way pipe 40. In this way, the collection of film edges is completed.

[0032] In summary, the edge suction device of this utility model for a high-barrier film high-speed slitting machine, through the cooperation of two edge suction flat tubes 10, two edge feeding guide tubes 20, a Y-shaped tee tube 30, a B-shaped tee tube 40, an edge suction fan 50, and an edge material collection unit 60, can collect the film edges after slitting. This saves on the core material for collecting process edge waste, avoids slippage and film breakage problems during high-speed slitting of process edge film material, improves slitting stability, ensures the quality of slitting products, and improves the efficiency of slitting production.
