Plastic sheet refers to the material used to produce thermoformed products such as disposable plastic cups, plates, bowls, dishes, boxes, etc. It is widely used in the packaging of food, vegetables, fruits, beverages, dairy products, industrial parts and other fields.

[0003] Plastic sheet preheating machine is an auxiliary device used to preheat plastic sheet during processing, so as to better perform subsequent processing such as shaping according to production process requirements. It has been widely used in the field of plastic sheet processing. Traditional plastic sheet preheating machines are generally equipped with heating rollers to heat them.

[0004] At present, the rollers of plastic sheet preheating machines on the market heat the plastic sheets by rotating the rollers. However, the plastic sheets to be heated cannot be limited during the heating process, which causes the plastic sheets to shake during the heating process, affecting the stability during the heating process. In addition, it is not convenient to adjust the height of the preheating roller according to the needs of the staff, so the staff need to bend over continuously during the loading process, which reduces the comfort of the staff during the loading process.
