Abstract

The invention discloses a paper tube hot extruder with a marking device. The paper tube hot extruder comprises a digital control table, a feeding mechanism, a screw transmission mechanism and a heating and extruding mechanism. An output end of the heating and extruding mechanism is provided with the marking device for marking a straight line on the outer surface of a paper tube when the paper tube is output. The marking device comprises a bracket, a marking pen, a spring and a bolt. The bracket is I-shaped; a through hole is formed on each of the three faces of the bracket; a pen point end of the marking pen passes through the through hole on the bottom face of the bracket; a pen body of the marking pen is supported through the through hole, so that the pen body is located between the top face and the bottom face of the bracket; a groove is formed at the tail part of the marking pen; a bolt is screwed in the through hole on the top face of the bracket which is sleeved at the bottom end of the bolt by tightly pressing one end of the spring of the marking pen; and the other end of the spring is located in the groove for finely adjusting a vertical position of the marking pen. With the adoption of the paper tube hot extruder with the marking device, hot extrusion and marking can be carried out simultaneously, so that the alignment requirement in a paper tube follow-up film rolling process is met, and the failure in film rolling caused by inclination of the film rolling is avoided.

Description

technical field

[0001] The invention relates to a paper tube heat extruder, in particular to a paper tube heat extruder with a marking device. Background technique

[0002] There are many kinds of numerically controlled heat extruders for paper tubes in the prior art, usually including a numerical control platform, a feeding mechanism, a screw transmission mechanism, and a heating extrusion mechanism. The extruded paper tubes have different sizes according to customer requirements.

[0003] The paper tube is used as the inner core of the film roll. For the paper tube with a length of more than 50cm, when rolling the film, since there is no reference starting position on the paper tube, the roll film is easily deflected, resulting in the failure of the roll film. Contents of the invention

[0004] The technical problem to be solved by the present invention is to provide a paper tube heat extruder with a marking device capable of drawing a straight line on the outer surface ...
