Description
Technical Field
[0001] This utility model belongs to the field of cutting device technology, specifically, it relates to a cutting device for a roll of transparent film. Background Technology
[0002] Breathable membranes, as a type of thin film material with special functions, have a wide range of applications in modern industry and daily life.
[0003] Breathable membranes have numerous common applications. In the medical field, they are widely used in surgical gowns, protective suits, wound dressings, and other products, providing reliable protection for medical staff and patients while ensuring normal skin respiration and reducing stuffiness and discomfort. In the food packaging industry, breathable membranes can be used for packaging fresh agricultural products such as fruits and vegetables, extending their shelf life by regulating the gas composition within the packaging. In the construction industry, breathable membranes can serve as waterproof and breathable layers for building roofs and walls, preventing rainwater from seeping into the building while expelling humid indoor air, maintaining the dryness and stability of the building structure.
[0004] The use of roll-type material for breathable membranes is primarily based on considerations of production efficiency and storage and transportation. During the production process, the breathable membrane is continuously produced and rolled into rolls, enabling large-scale, continuous production, significantly improving production efficiency and reducing production costs. Simultaneously, roll packaging facilitates storage and transportation, saving considerable space and reducing losses and costs during transportation compared to bulk or sheet packaging.
[0005] Currently, roll-to-roll breathable membranes are mainly cut using traditional scissor-cutting or stamping methods. The disadvantages of these methods are poor cutting accuracy and low efficiency. Therefore, improvements are necessary. Utility Model Content

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] One embodiment of this application provides a cutting device for a roll-type transparent film, such as...

Cutting unit 4 is mounted on bracket 1; It also includes a clamping and pushing unit 7, which is mounted on the bracket 1; the clamping and pushing unit 7 clamps the movable end of the transparent film and moves it to a preset position, and the cutting unit 4 cuts the transparent film at the preset position.
[0023] In one embodiment, a dust removal unit 5 is also included. The dust removal unit 5 is mounted on the bracket 1. The dust removal unit 5 removes dust from the transparent film and then cuts it.
[0024] Specifically, such as Figure 1 As shown, the roll material carrying unit 2 includes a material shaft 21, one end of which is rotatably mounted on the bracket 1 via a bearing, and the other end of which is suspended; a roll of transparent film is mounted on the material shaft 21, and the roll of transparent film can rotate relative to the bracket 1; It also includes a limiting plate 22, which is movably mounted on the material shaft 21. After the roll of transparent film is mounted on the material shaft 21, the limiting plate 22 is then mounted on the other end of the material shaft 21. The limiting plate 22 limits the roll of transparent film to prevent it from falling out of the material shaft 21. An adjustable set screw 23 is installed on the limiting plate 22. The adjustable set screw 23 cooperates with the material shaft 21 to fix or loosen the limiting plate 22 and the material shaft 21.

[0025] Furthermore, such as Figure 1As shown, it also includes a material guiding unit 6, which is mounted on the bracket 1. The material guiding unit 6 guides the transparent film into a preset position. The material guiding unit 6 is located below the roll material carrying unit 2. The material guiding unit 6 includes a first guide wheel 61 and a second guide wheel 62 arranged at intervals. The first guide wheel 61 and the second guide wheel 62 are respectively rotatably connected to the bracket 1. The center of the first guide wheel 61 is higher than the center of the second guide wheel 62. After the movable end of the roll transparent film is tangent to the upper surface of the first guide wheel 61 and then tangent to the lower surface of the second guide wheel 62, it enters the positioning unit 3.
[0026] Specifically, the positioning unit 3 includes a first positioning roller 31 and a second positioning roller 32 spaced apart, which are rotatably mounted on the bracket 1. A first lifting roller 33 is provided directly above the first positioning roller 31, and a second lifting roller 34 is provided directly above the second positioning roller 32. The first positioning roller 31 and the first lifting roller 33 work together to limit the transparent film, preventing it from deviating during movement. The second positioning roller 32 and the second lifting roller 34 work together to limit the transparent film, preventing it from deviating during movement. The structure of the second lifting roller 34 is the same as that of the first lifting roller 33; the first lifting roller 33 includes a first lifting cylinder 331, which is mounted on the bracket 1; the movable end of the first lifting cylinder 331 is movably mounted with a third positioning roller 332 via a mounting seat; the dust removal unit 5 is located between the first positioning roller 31 and the second positioning roller 32.
[0027] Furthermore, such as Figures 1-2 As shown, the positioning unit 3 also includes a pressing sheet metal 35, which is mounted on the bracket 1; the pressing sheet metal 35 is located to the right of the second positioning roller 32, and further presses the transparent film.
[0028] Specifically, the dust removal unit 5 includes a dust removal chamber 51, which is mounted on the support 1. A through-hole channel for the transparent membrane to pass through is formed inside the dust removal chamber 51. An air inlet pipe 52 and an air outlet channel are installed on the dust removal chamber 51, located on both sides of the dust removal chamber 51. The air inlet pipe 52 and the air outlet channel are respectively connected to the through-hole channel. Air is blown onto the air inlet pipe 52, and the airflow blows away dust and other impurities on the transparent membrane, which then exits through the air outlet channel. It should be noted that the principle and process of air blowing dust removal are existing technologies and will not be described in detail here.
[0029] Specifically, such as Figure 1As shown, the cutting unit 4 includes a cutting pad 41, which is mounted on the bracket 1; a roller cutter 42 is provided above the cutting pad 41, and a cutting groove 411 that cooperates with the roller cutter 42 is provided on the cutting pad 41; the roller cutter 42 cuts the transparent film that enters the preset position of the cutting pad 41; the roller cutter 42 is a purchased part, and its operation and structure will not be described in detail. The bracket 1 is equipped with a first transverse linear module 43, which is a purchased component and its structure will not be described in detail. The movable end of the first transverse linear module 43 is equipped with a tool holder 44, and the hobbing cutter 42 is rotatably mounted on the tool holder 44.
[0030] Furthermore, such as Figures 1-2 As shown, the clamping and pushing unit 7 includes a pushing cylinder 71 mounted on the bracket 1. A clamping cylinder 72 is mounted on the movable end of the pushing cylinder 71, and a clamping block 73 is mounted on the movable end of the clamping cylinder 72. There are two clamping blocks 73. Under the action of the clamping cylinder 72, the two clamping blocks 73 clamp the transparent film at a preset position. Then, the pushing cylinder 71 drives the clamping cylinder 72 to move to the preset position, thereby sending the transparent film to the preset position of the cutting unit 4, so as to facilitate the cutting unit 4 to cut the transparent film.
[0031] During operation, the movable end of the roll of transparent film on the case file material carrying unit 2 passes through the guiding unit 6, the positioning unit 3, and the dust removal unit 5 in sequence. Then, the clamping and pushing unit 7 clamps the movable end of the roll of transparent film. Then, the pushing cylinder 71 drives the clamping cylinder 72 to move to the preset position, thereby sending the transparent film to the predetermined position of the cutting unit 4, and the cutting unit 4 cuts the transparent film.
[0032] The advantages of the roll-type transparent film cutting device of this application, as described above, are as follows: 1. The cylinder pull-out and the roller cutter work together. The cylinder can provide a stable and controllable pulling force, smoothly and accurately pulling the roll-type breathable film to the designated position, preparing it for subsequent cutting processes. 2. The contact between the roller cutter and the breathable film is a rolling friction, which causes less damage to the breathable film compared to the sliding friction of scissor cutting and the impact force of stamping cutting. This better maintains the physical properties and breathability of the breathable film, reducing the scrap rate.
