Description

Technical Field

[0001] This utility model relates to the field of coating and laminating equipment technology, and in particular to a coating and laminating machine with a membrane peeling and recycling function. Background Technology

[0002] A coating laminating machine is a device used to uniformly coat a film substrate with coating liquids such as adhesives and release agents, and then laminate it with other film materials after drying and curing. However, existing coating laminating machines have limitations in peeling off the back film of the substrate or the release film after lamination. They usually require an additional peeling and rewinding machine to complete the peeling process before being introduced into the subsequent coating operation, resulting in low production efficiency and easy damage to the substrate.

[0003] In the prior art, although a peeling device is added between the unwinding unit and the coating unit, it is only suitable for peeling the back film on the base film under direct coating, and cannot meet the peeling requirements of the release film after transfer coating or lamination.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a coating and laminating machine with a membrane peeling and recycling function to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0006] To overcome the shortcomings of the prior art, the present invention aims to disclose a coating and laminating machine with a film peeling and recycling function, so as to solve the problems of single peeling function and low production efficiency in the prior art.

[0007] This utility model discloses a coating and laminating machine with a membrane peeling and recycling function, comprising:

[0008] The processing line consists of a first unloading unit, a compounding unit, a storage unit, a tensioning and separating unit, and a take-up unit arranged sequentially. The first unloading unit is used to unwind and pre-treat the processing material; the compounding unit is used to combine materials from different rolls; the storage unit serves as a temporary storage area and uses floating rollers to adjust the speed difference between the preceding and following processes; the tensioning and separating unit ensures that the substrate maintains constant tension during transmission and separates different coating sections to prevent undried coatings from contacting and contaminating or sticking together; and the take-up unit is used to collect the processed material.

[0009] The film peeling unit is detachably disposed between any adjacent units in the processing line. It includes an upper peeling roller and a lower peeling roller that are pressed together. The upper peeling roller is a rigid roller body, and the surface of the lower peeling roller is covered with an elastic layer. The film peeling unit also includes a first take-up roll disposed on the discharge side of the lower peeling roller.

[0010] Preferred technical solution: The upper peeling roller is a metal roller or a hard rubber roller, and the elastic layer of the lower peeling roller is a silicone layer or a polyurethane layer.

[0011] Preferred technical solution: The surfaces of the upper and lower peeling rollers are provided with an anti-stick coating to prevent materials from sticking together.

[0012] Preferred technical solution: An electrostatic elimination device is provided at the membrane peeling unit, located at the gap between the upper peeling roller and the lower peeling roller, to eliminate static electricity generated during the peeling process.

[0013] Preferred technical solution: The upper and lower stripping rollers can be interchanged, and the first take-up roll and the lower stripping roller are always on the same side to adapt to different stripping requirements.

[0014] Preferred technical solution: The take-up unit includes a second take-up roll and a guide wheel group. The second take-up roll is a take-up device with automatic roll changing and cutting function to improve take-up efficiency.

[0015] Preferred technical solution: The second take-up roll is a take-up device with automatic roll changing and cutting function to improve take-up efficiency.

[0016] Preferred technical solution: The first feeding unit includes an upper film feeding roll and a lower film feeding roll.

[0017] Preferred technical solution: A drying unit is also provided between the upper film unwinding roll and the composite unit to ensure the drying effect of the coating material.

[0018] Preferred technical solution: The processing line also includes a coating unit and a correction unit to realize coating and material correction functions.

[0019] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0020] 1) The detachable membrane peeling unit enables integrated operation of coating, lamination and peeling recycling, which significantly improves production efficiency.

[0021] 2) The membrane stripping unit can be set between any adjacent units on the processing line to adapt to different process requirements;

[0022] 3) The combination of rigid and elastic rollers, along with an anti-stick coating and static elimination device, effectively reduces substrate damage and static interference.

[0023] 4) The receiving unit is equipped with an automatic roll changing and cutting function, which further improves the automation level of the equipment. Attached Figure Description
