Film cutting device

Abstract

The invention provides a film cutting device comprising a machine frame and a conveyer belt assembly. The conveyer belt assembly comprises a first rolling shaft, a second rolling shaft and a conveyerbelt. The conveyer belt is connected to the first rolling shaft and the second rolling shaft in a sleeving manner. The film cutting device further comprises a motor, a gear transmission assembly, pullrods, a cutter, a connection rod mechanism and a one-way bearing. An output shaft of the motor is connected with the input end of the gear transmission assembly. One end of each pull rod is rotationally connected with the gear transmission assembly in an eccentric manner. The other end of each pull rod is rotationally connected with the upper end of the cutter. The cutter is located above the conveyer belt. The input end of the connection rod mechanism is connected with the upper end of the cutter. The output end is connected with the first rolling shaft through the one-way bearing. The motoris fixed to the machine frame. The motor drives the cutter to move up and down through the gear transmission assembly and the pull rods, the first rolling shaft is driven to conduct intermittent rotation through the connection rod mechanism and the one-way bearing, and the two actions of film cutting and feeding are achieved. The film cutting device is simple in system and saves energy.

Description

Technical field [0001] The invention relates to the technical field of film cutting equipment, in particular to a film cutting device. Background technique [0002] The film cutting device mainly needs to complete two actions: feeding and film cutting. Most of the existing film cutting devices separate the feeding and cutting power sources. For example, the Chinese Utility Model Patent Publication No. CN202716525U discloses a film cutting device. The motor drives the conveyor belt to move, and the hot cutting knife is fixed at the bottom end of the lower beam. The lower beam moves vertically reciprocating relative to the upper beam, and the cylinder drives the lower beam to move relative to the upper beam. Although it has the advantages of independent control of feeding and film cutting and convenient maintenance, it requires two power sources: cylinder and motor. Installation of pneumatic system is complicated and consumes much energy. Summary of the invention [0003] The tech...

Most of the existing film cutting devices separate the power source of feeding and film cutting. For example, the Chinese utility model patent with the publication number CN202716525U discloses a film cutting device. The motor drives the conveyor belt to move, and the hot cutter is fixed on the bottom of the lower beam. The lower beam reciprocates vertically relative to the upper beam, and the cylinder drives the lower beam to move vertically relative to the upper beam. Although it has the advantages of independent control of feeding and film cutting, and convenient maintenance, it requires two power sources, the cylinder and the motor. Install a pneumatic system, the system is complex and consumes a lot of energy
