Description

Technical Field

[0001] This invention relates to the field of roll material production, and more particularly to a waste removal process for roll material production. Background Technology

[0002] Roll or film materials are commonly used in daily life. Examples include double-sided tape and protective film. These products often require rotary cutting machines during production. This is especially true for materials with unusual shapes, such as those needing to be cut in the middle. The waste from cutting needs to be removed promptly, particularly in assembly line production where waste can easily accumulate. If not cleaned up in a timely manner, it can impact subsequent production.

[0003] In current production processes, ejector pins are typically used to push out waste material, which is then adhered to other membrane materials for final removal. This method results in material waste and increased costs, hindering factory profitability. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a waste suction process for roll material production.

[0005] The technical solution of this invention is: a waste absorption process for roll material production, comprising:

[0006] The first, second, third, and fourth workstations are set up in sequence, and the raw materials pass through the four workstations in sequence, while the molded products flow out from the fourth workstation.

[0007] From top to bottom, the main material assembly, release film assembly, and original film assembly are arranged sequentially on the feeding side of the first station;

[0008] The first station includes a first rubber roller and a first steel roller arranged in parallel, and the three raw materials are stacked and pass between the first rubber roller and the first steel roller;

[0009] The second work station includes a parallel-arranged cutter roller and a second steel roller. The cutter roller cuts the main material and release film on the surface of the second steel roller. The cutter roller has a hollow cavity inside, which is connected to the cutter. A negative pressure device is installed on the hollow cavity.

[0010] The third station includes a third rubber roller and a third steel roller arranged in parallel, and the third station presses the product after the second station.

[0011] The fourth station includes a parallel-arranged cutting roller and a fourth steel roller, the cutting roller dividing the product pressed in the third station; and

[0012] A peeling component is installed at the discharge end of the fourth station to separate the molded product from the original film.

[0013] Furthermore, the main material assembly includes a main material feeding roller, a first main material receiving roller, and a second main material receiving roller arranged in parallel. The first main material receiving roller is arranged on the feeding side of the first station, and the second main material receiving roller is arranged above the second station. The main material is placed on the main material feeding roller, and the release film of the main material is collected by the first main material receiving roller. The main material waste after being cut at the second station is collected by the second main material collecting roller.

[0014] Furthermore, the main material assembly also includes a main material guide roller, which is in contact with the first adhesive roller. After passing through the main material guide roller, the release film and the main body of the main material are separated, avoiding the influence of impurities on the main body of the main material.

[0015] Furthermore, the release film assembly includes: a release film feeding roller and at least one release film guide roller, wherein the release film is fed from the release film feeding roller and enters the first station after passing through at least one release film guide roller.

[0016] Furthermore, the original film assembly includes: an original film feeding roller and an original film receiving roller, wherein the original film feeding roller is located on the feeding side of the first station, and the original film receiving roller is located outside the peeling assembly. That is, the original film passes through four stations and the peeling assembly in sequence.

[0017] Furthermore, the original film is made of PET material. PET contains polyethylene terephthalate, the most important type of thermoplastic polyester, also known as polyester resin. It is a condensation polymer of terephthalic acid and ethylene glycol.

[0018] Furthermore, the original membrane should not be cycled more than 10 times.

[0019] Furthermore, the blade edge shape on the cutter roller is a closed shape, and the blade edge shape is at least one of a circle, a square, and a triangle. This ensures that the cutting waste can be separated from the main material.

[0020] Furthermore, the negative pressure device can be a vacuum cleaner or a vacuum pump. The appropriate device can be selected based on actual production needs during factory use. It is also essential to ensure a tight seal to achieve continuous adsorption.

[0021] Furthermore, in all four stations, the steel rollers are located directly below the other rollers that are arranged in conjunction with them.

[0022] Furthermore, the cutting roller performs straight-line cutting.

[0023] Furthermore, the peeling assembly includes a peeling block, a raw film receiving roller disposed below the peeling block, and a collecting cylinder disposed outside the peeling block. This achieves the separation of the molded product and the raw film.

[0024] The beneficial technical effects of this invention are: the waste absorption process designed in this application reduces the use of acrylic protective film, provides a new waste collection method, and is more reliable, simpler and more efficient, which ensures large-scale product production and reduces factory costs.

The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0038] See appendix Figure 1-3 As shown, a waste absorption process for roll material production in this embodiment includes:

[0039] The first station 1, the second station 2, the third station 3, and the fourth station 4 are set up in sequence, and the raw materials pass through the four stations in sequence, while the molded products flow out from the fourth station 4.

[0040] From top to bottom, the main material assembly 5, the release film assembly 6, and the original film assembly 7 are arranged on the feeding side of the first station 1.

[0041] The first station 1 includes a first rubber roller 11 and a first steel roller 12 arranged in parallel. After the three raw materials are stacked, they pass between the first rubber roller 11 and the first steel roller 12.

[0042] The second station 2 includes a parallel cutter roller 21 and a second steel roller 22. The cutter roller 21 cuts the main material and release film on the surface of the second steel roller 22. The cutter roller 21 is configured with a hollow cavity, which is connected to the cutter. A negative pressure device 23 is installed on the hollow cavity.

[0043] The third station 3 includes a third rubber roller 31 and a third steel roller 32 arranged in parallel. The third station 3 presses the product after the second station 2.

[0044] The fourth station 4 includes a cutting roller 41 and a fourth steel roller 42 arranged in parallel. The cutting roller 41 divides the products pressed by the third station 3; and

[0045] A peeling component 8 is installed at the discharge end of the fourth station 4. The peeling component 8 separates the molded product from the original film.

[0046] Furthermore, the main material assembly 5 includes a main material feeding roller 51, a first main material receiving roller 52, and a second main material receiving roller 53 arranged in parallel. The first main material receiving roller 52 is arranged on the feeding side of the first station 1, and the second main material receiving roller 53 is arranged above the second station 2. The main material is placed on the main material feeding roller 51. The release film of the main material is collected by the first main material receiving roller 52, and the main material waste after being cut at the second station 2 is collected by the second main material collecting roller.

[0047] Furthermore, the main material assembly 5 also includes a main material guide roller 54, which is in contact with the first adhesive roller 11. After passing through the main material guide roller 54, the release film and the main body of the main material are separated, thus avoiding the influence of impurities on the main body of the main material.

[0048] Furthermore, the release film assembly 6 includes: a release film feeding roller 61 and at least one release film guide roller 62. The release film is fed from the release film feeding roller 61 and enters the first station 1 after passing through at least one release film guide roller 62.

[0049] Furthermore, the original film assembly 7 includes an original film feeding roller 71 and an original film receiving roller 72. The original film feeding roller 71 is located on the feeding side of the first station 1, and the original film receiving roller 72 is located outside the peeling assembly 8.
