[0002] With the improvement of people's living standards and the growing domestic demand, the use of packaging plastic thermoformed sheets is becoming more and more extensive, and the amount of use is also increasing year by year. The extruded sheet production line generally needs to trim the sheets. The existing trimming method is to manually press a ruler on the plastic sheet, and then use a knife to cut the plastic sheet along the ruler. However, the existing cutting method has extremely low work efficiency and poor accuracy. At the same time, the labor intensity of the staff is high and cannot meet the production needs. Therefore, it is urgent to design an automatic plastic sheet cutting device.

[0003] When the existing automatic plastic sheet cutting device is installed and used, the plastic sheet is cut into different lengths, resulting in a relatively single usage scenario of the device; since the loading and unloading work cannot be completed automatically, the user is required to manually load and unload the material, straighten the plastic sheet, align the ruler to measure the length and then cut it. This series of operations is relatively complicated, which not only reduces the cutting speed, but also makes it easy to hit the cutter, which is dangerous and has a certain adverse effect on people's use process. In order to solve the shortcomings of the existing technology, we propose an automatic plastic sheet cutting device. Utility Model Content
