Description

Technical Field

[0001] This utility model relates to the field of TPU film technology, and in particular to a TPU film lamination and bonding machine. Background Technology

[0002] TPU film is a film material made of thermoplastic polyurethane elastomer. It has high strength, and its tensile strength is 2-3 times that of pure natural rubber and synthetic rubber. TPU film lamination and bonding machine is a device used to tightly bond multiple layers of TPU film together. The pressure system applies a certain pressure, so that under the combined action of heat and pressure, the molecular chain segments on the surface of the TPU film move more rapidly, penetrate and entangle with each other, thereby achieving adhesion.

[0003] In daily work, it has been found that existing TPU film lamination and bonding machines are not convenient for cleaning the heated and extruded areas. These areas are prone to getting dirty, which adheres to the surface of the equipment, causing uneven heating and seriously affecting the bonding effect of the TPU film. Currently, cleaning mainly relies on manual operation, which not only increases the difficulty of operation but also makes it easy for operators to get injured during the cleaning process, greatly reducing work efficiency and safety. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology, such as the inconvenience of cleaning the heated and extruded area, the ease with which the heated and extruded area becomes stained, the adhesion of these stains to the surface of the equipment, the uneven heating, and the inconvenience of manual cleaning. Therefore, this invention proposes a TPU film lamination and bonding machine.

The output end of the motor is fixedly connected to one end of the screw rod. Through the above components, the motor can drive the screw rod to rotate, and the screw rod controls the movable seat to move on the sliding rod to achieve cleaning.

[0008] Preferably, the positioning part includes a first protrusion and a second protrusion. The first protrusion and the second protrusion are fixedly connected to the surfaces of the scraper and the movable seat, respectively. The inner wall of the second protrusion is threaded with a second screw. The second screw is inserted into the inner wall of the first protrusion.

[0011] Preferably, the collection tank is composed of a tank body and multiple filter holes opened on the surface of the tank body.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1.

[0026] Specifically, the drive unit 74 includes two hollow seats 741 fixed on the surface of the body 1. The inner walls of the two hollow seats 741 are rotatably connected to a screw 742. The screw 742 is threadedly connected to the inner wall of the movable seat 72. A motor 743 is fixedly connected to the surface of the hollow seats 741. The output end of the motor 743 is fixedly connected to one end of the screw 742.

[0027] In this embodiment: the motor 743 can drive the screw 742 to rotate, and the screw 742 controls the moving seat 72 to move on the sliding rod 71 to achieve cleaning.
