Description

Technical Field

[0001] This utility model relates to the technical field of die-cutting equipment, and in particular to a double-sided adhesive die-cutting device. Background Technology

[0002] The core function of the double-sided tape die-cutting device is to process rolls or sheets of double-sided tape into single or continuous adhesive patches of specific shapes and sizes, and to achieve automatic waste removal, so as to meet the precise bonding requirements in subsequent production.

[0003] In the existing technology, there are a large number of double-sided tape die-cutting devices. Taking CN202311338309.7, an automatic waste removal device for a double-sided tape die-cutting machine as an example, it is equipped with an automatic waste removal device to improve production efficiency. Taking CN202420318177.5, a double-sided tape die-cutting device as an example, it includes a base 9, a mounting frame fixedly connected to the middle of the base 9, and a hydraulic cylinder fixedly installed on the top of the mounting frame. The piston rod end of the hydraulic cylinder extends into the mounting frame and is fixedly connected to a lifting plate. Die-cutting blades are equidistantly connected to the bottom of the lifting plate. An operating table is fixedly connected to the top of the base 9, and a cutting groove that cooperates with the die-cutting blade is opened on the top of the operating table. The die-cutting blade is located directly above the cutting groove. A receiving groove is connected to the side of the operating table at the top of the base 9. This double-sided tape die-cutting device can push out the double-sided tape that is attached to the inside of the die-cutting blade after die-cutting, avoiding the situation where the double-sided tape is attached to the inside of the die-cutting blade after die-cutting, which increases the difficulty of receiving the material. The lifting and lowering of the positioning pressure plate can be controlled by the operation of the electric telescopic rod, so that the positioning pressure plate can press down and position the double-sided tape, avoiding the displacement of the die-cutting part of the double-sided tape during the die-cutting process.

[0004] However, the existing technologies and even the actual equipment mentioned above rarely take into account the situation where double-sided tape tends to stick to the die-cutting blades during die-cutting, causing the double-sided tape to shift during the die-cutting process. Currently, factories mostly clean the glue off the die-cutting blades periodically to ensure production quality, but this requires stopping the machine, which is not ideal. Utility Model Content
