Technical Field

The utility model relates to a hose processing technology field, more specifically relates to a hose cutting device.

Background

The pipe is used as a medium for conveying fluid and is widely applied to industrial production and daily life. The hose is characterized in that the hose is flexible, the design of the hose can be changed greatly according to working conditions and performance requirements, and the hose commonly used in daily life is made of PVC or PE at present.

In the production process of the hose, the hose is continuously extruded from a port of an extruder, is shaped through cooling, drying and other processes, and is conveyed to a cutting device for cutting. Before the sizing processes such as cooling, the hose is inflated while being produced, certain air pressure is generated through internal air to shape the hose, if the air pressure in the hose is too large, the hose wall can be thinned or cracked, if the air pressure is too small, the hose can be collapsed, deformed and even adhered, and the quality of a produced product is influenced, so that one end of the produced hose is kept closed as much as possible, the inner space of the hose is in a state similar to sealing, and the phenomenon that the air pressure in the hose is changed too much or air leakage is caused is prevented.

When the machine is produced, generally, a worker is required to operate beside the output end of the hose, the produced end of the hose needs to be bent or pinched and fixed by the worker, and then the hose is cut off when the set length is reached, so that the labor cost is greatly increased, and the efficiency is very low. In addition, the existing automatic cutting device can only simply carry out feeding and cutting, a necessary locking device is not needed during cutting operation, the feeding and cutting parts are not well matched, so that the section is not smooth during cutting, the defective rate is high, and the problems that the hose needs to be sealed in a sealing mode and excessive air leakage is prevented are not solved.
