Description

Technical Field

[0001] The utility model relates to the technical field of film cutting equipment, in particular to a film cutting mechanism for a laminating machine. Background Art

[0002] Laminating machines can be divided into two categories: instant laminating machines and pre-coating laminating machines. They are special equipment for paper, board materials, and film mounting. After being pressurized by rubber rollers and heating rollers, they are combined to form a paper-plastic product. The process of instant laminating machines includes three parts: gluing, drying, and hot pressing. It has a wide range of applications and stable and reliable processing performance. It is a widely used laminating equipment in China. Pre-coating laminating machines do not have gluing and drying parts, are small in size, low in cost, and flexible and convenient to operate. They are not only suitable for laminating processing of large quantities of printed materials, but also suitable for laminating processing of small quantities and scattered printed materials such as automated desktop office systems.

[0003] The existing coating of glass plates is mostly carried out by manually cutting a single glass plate after coating. When cutting and separating the coated glass plates, the cut edges are often irregular, and the edge of the product may even be cut, resulting in a significant increase in the defective rate of the product, reducing work efficiency and being unfavorable for processing. In addition, the existing laminating machines and film cutting mechanisms are mostly separated, resulting in low efficiency in coating and cutting of glass plates. Utility Model Content

[0004] The utility model aims to provide a film cutting mechanism for a laminating machine to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A film cutting mechanism for a laminating machine comprises a laminating mechanism, wherein a film cutting mechanism is fixedly arranged in the laminating mechanism;

[0007] The film cutting mechanism includes a fixed arm, a cylinder is fixedly connected to the top of the fixed arm, a lifting plate is fixedly connected to the bottom of the cylinder, a plurality of pressure rods are fixedly connected to the bottom of the lifting plate at equal distances, a pressure plate is fixedly connected between the bottoms of the plurality of pressure rods, four mounting blocks are fixedly connected to the bottom of the pressure plate symmetrically about its vertical center plane, a film cutting knife is inserted between two adjacent mounting blocks, and a threaded column inserted into the film cutting knife is screwed together between two opposing mounting blocks.

[0008] Furthermore, a film pressing shell is slidably connected between the plurality of pressing rods, a cutting groove is provided at the center of the bottom of the film pressing shell, and two rubber pads are symmetrically fixedly connected to the bottom of the film pressing shell.

[0009] Furthermore, the exteriors of the plurality of pressure rods are sleeved with deformation springs fixedly connected to the film shell.

[0010] Furthermore, the coating mechanism includes two support frames, both ends of one of the support frames are rotatably connected to a conveying roller 1, and both ends of the other support frame are rotatably connected to a conveying roller 2, a conveyor belt is sleeved between the two conveying rollers 1 and the two conveying rollers 2, a double-groove pulley is fixedly sleeved at the end of the conveying roller 2, a synchronous wheel 1 is fixedly sleeved at the end of the conveying roller 1, a synchronous belt 1 is sleeved between the double-groove pulley and the synchronous wheel 1, the output end of the driving motor is fixedly connected at the center position of the conveying roller 2, and a connecting plate is fixedly connected between the two support frames.

[0011] Furthermore, two support columns are symmetrically fixedly connected to the support frame, a film placing roller is rotatably connected between the two support columns, a second synchronous wheel is fixedly sleeved on the end of the film placing roller, a second synchronous belt is sleeved between the second synchronous wheel and the double-groove pulley, and a protective film is wound on the film placing roller.

[0012] Furthermore, a coating roller is provided on the conveyor belt, and both ends of the coating roller are rotatably connected to positioning seats, and the tops of the two positioning seats are fixedly connected to sliding rods, the outer sliding sleeves of the sliding rods are slidably sleeved with sleeves, the tops of the sliding rods are fixedly connected with extrusion springs, and the tops of the sleeves are fixedly connected with lifting blocks, one of the lifting blocks is screwed with an adjusting screw rod rotatably connected to the support frame, and the other lifting block is slidably sleeved with a limiting column.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By placing multiple sheets on the conveyor belt for conveying, the driving motor can drive the conveyor roller 1 and the conveyor roller 2 to rotate in the same direction, so that the two conveyor belts can drive multiple sheets to continuously move from the bottom of the coating roller. The driving motor can also drive the film-releasing roller to rotate and release the protective film. Then the protective film is attached to the surface of the sheet after bypassing the coating roller.

Therefore, the protective films on the two adjacent sheets will be automatically separated.
