Description

Technical Field

[0001] The utility model relates to the technical field of paper tube production, in particular to a paper tube clamping and cutting machine. Background Art

[0002] Paper tubes are tubular objects made from paper sheets. Most paper tubes are spiral paper tubes and seamless paper tubes. After processing, paper tubes are mostly long paper tubes and need to be cut to length according to actual usage.

[0003] A Chinese patent discloses a tube cutting device for paper tube production and processing, with the publication number CN215920610U, comprising a processing table, a first motor is fixedly installed in the middle of the left side of the processing table, the second motor driving output end is connected to the transmission shaft, and the other end of the transmission shaft is fixedly connected to a turntable, and multiple groups of equally spaced feeding rods are movably installed on the outer side of the right end of the turntable, and the left sides of the two adjacent groups of feeding rods are connected by transmission belts. When the feeding rod with the paper tube sleeved is rotated to the upper side, the hydraulic push rod on the support plate will drive the two groups of limit rods to move downward, so that the rotating cutting rod cuts the paper tube, and the rotation direction of the motor shaft of the third motor can be controlled by the bracket, the roller and the third motor to change the rotation direction of the roller, which can not only push the cut paper tube out of the feeding rod, but also when the rotation direction of the roller is opposite, a new paper tube can be sleeved on the feeding rod.

[0004] However, the following disadvantages still exist: the device uses the second motor to drive the cutting rod to rotate, but the cutters on the cutting rod cannot move along the cutting rod, and the gap between the cutters cannot be adjusted, so that the device cannot adjust the cutting length of the paper tube as needed. Therefore, we propose a paper tube clamping and cutting machine to solve this problem. Utility Model Content
