In recent years, relevant Chinese authorities have promulgated a series of industrial policies and plans conducive to the development of the industrial tape industry, laying a solid institutional foundation for its continued growth.
[0003] Die-cutting is a crucial step in the process of industrial tapes being used in mobile phone assembly to bond numerous components and protect their appearance. Die-cutting involves using a die-cutting knife to create a die-cutting plate based on the customer's product component drawings. Then, under pressure, the industrial tape is cut into the desired shape or cut.
[0004] The geometric shapes die-cut from existing tapes are relatively complex and need to be prepared into a multi-layer structure. Due to the differences in the sizes of electronic product components of different specifications, when processing the same product on tapes of different thicknesses, different knife rollers need to be replaced according to the thickness of the tape, which increases costs.

Due to the differences in the sizes of electronic product components of different specifications, when processing the same product on tapes of different thicknesses, different knife rollers need to be replaced for processing according to the different thicknesses of the tape, which increases costs.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: the present invention includes a base provided at the bottom, a bracket provided at the top of the base, and a fixed die-cutting roller installed on the bracket, and also includes an adjustment component and an adjustable die-cutting roller, wherein the adjustment component is installed at the top of the bracket, and the adjustable die-cutting roller is installed on the adjustment component;
[0007] The adjustment assembly includes a shell, an inner cavity, a screw, a guide column, a lifting block, a crank, a screw hole, a guide hole and a bearing. The shell is symmetrically installed on the bracket. An inner cavity is opened in the middle of the shell, and a screw is installed in the middle of the inner cavity. Two guide columns are symmetrically fixed on both sides of the screw, and a lifting block is installed on the screw and the guide column. A crank is installed at one end of the screw.

[0012] Preferably, the two screw rods installed on the housing are connected and driven by a synchronous wheel and a synchronous belt.
[0013] Beneficial effects: When the utility model is used, the tape to be die-cut passes between the fixed die-cutting roller and the adjustable die-cutting roller, and die-cutting is performed through the cooperation of the fixed die-cutting roller and the adjustable die-cutting roller. When the distance between the fixed die-cutting roller and the adjustable die-cutting roller needs to be adjusted to suit tapes of different thicknesses, the crank is turned, and the rotation of the crank drives the two screws to rotate synchronously. The rotation of the screws cooperates with the wire holes opened on the lifting block, so that the lifting block moves on the screws, and the movement of the lifting block drives the adjustable die-cutting roller installed thereon to move, thereby achieving the purpose of adjusting the distance between the fixed die-cutting roller and the adjustable die-cutting roller.
