Description

Technical Field

[0001] The utility model relates to the technical field of notch machines, in particular to a plastic bottle notch device. Background Technique

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Plastic bottles are widely made of polyester, polyethylene, and polypropylene as raw materials. After adding the corresponding organic solvents and being heated at high temperature, they are plastic containers formed by blow molding, extrusion blow molding, or injection molding through plastic molds. The mouths of various plastic bottles for canning are closed after being formed on the blow molding machine and cannot be directly used for canning. The excess part at the bottle mouth needs to be cut off.

[0003] The utility model patent with the publication number of CN218700614U discloses a notch machine for plastic bottle processing, including a machine body, a conveyor table, and a cleaning device. The bottom of the machine body is fixedly connected to the conveyor table. A cleaning device is arranged on the left side of the conveyor table, and the bottom of the fixing device is fixedly connected to the conveyor belt. By arranging the fixing device on the surface of the conveyor belt, the fixing device avoids the direct contact between the staff and the notch machine and solves the problem that plastic bottles are prone to tipping during the conveying process on the conveyor belt. By arranging the cleaning device on the left side of the machine body, the cleaning device controls the brush head through a motor to clean the particles attached to the plastic bottle body, and at the same time, the spray head wets the particles, making the particles on the plastic bottle body easier to be wiped off, saving the processing time of subsequent processes and saving time costs.
