Description

Paster cutting device Technical Field The utility model relates to the technical field of patch cutting, in particular to a patch cutting device. Background The electronic component patch is mainly used for achieving miniaturization and high integration of electronic products and improving production efficiency. The surface mount technology, also known as Surface Mount Technology (SMT), is a process of directly mounting electronic components to the surface of a Printed Circuit Board (PCB). Through this kind of mode, can reduce the volume of electronic product greatly, adapt to modern electronic equipment light, small and exquisite trend, when the paster uses, need cut into suitable size with the paster through the paster cutting device. When the patch cutting device is used, the patch cutting device can only cut the fixed thickness or size of the patch, and can not cut different thicknesses or sizes at the same time, so that the patch cutting device has limitation in use, and therefore the existing requirements are not met, and the patch cutting device is provided. Disclosure of utility model The utility model aims to provide a patch cutting device, which solves the problem that the patch cutting device provided in the background art can only cut the fixed thickness or size of a patch and can not cut different thicknesses or sizes at the same time, so that the use is limited. In order to achieve the purpose, the patch cutting device comprises a workbench, wherein two sides of the upper end of the workbench are fixedly connected with supporting rods, a supporting plate is fixedly connected between the top ends of the two supporting rods, the bottom end of the supporting plate is connected with a movable seat through a cylinder in a driving mode, two sides of the bottom end of the movable seat are fixedly connected with fixing plates, a rolling shaft is connected between the two fixing plates through a motor in a driving mode, a plurality of cutting knives are arranged on the outer surface of the rolling shaft, and annular seats which are connected to the outer surface of the rolling shaft in a sliding mode are fixedly connected to the two sides of the outer surface of each cutting knife. Preferably, the front and rear of the outer surface of the roller are provided with sliding grooves, and the inner side of each annular seat is fixedly connected with a sliding block which is in sliding connection with the inside of the sliding groove. Preferably, the movable groove is arranged in the annular seat up and down, the limiting plate is connected in a sliding manner in the movable groove, and a spring is fixedly connected between the upper end of the limiting plate and the inner wall of the movable groove.
