Slitter machine unrolling fixing device and high-speed slitter machine

Abstract

The invention discloses a slitter machine unrolling fixing device and a high-speed slitter machine. The slitter machine unrolling fixing device comprises a cylindrical outer shell and a center shaft which is installed in the outer shell in a rotatable mode. An installation flange is arranged at one end of the center shaft, and at least one ejecting mechanism is arranged in the axial direction of the center shaft. The ejecting mechanism comprises a cam and at least three ejecting blocks. The cross section of the cam is a regular polygon. The number of sides of the regular polygon is the same as that of the ejecting blocks. The cam is arranged on the center shaft, and the center line of the cam coincides with that of the center shaft. Radial holes are evenly formed in the periphery wall of the outer shell and correspond to all the ejecting blocks. The shape of the radial holes is matched with that of the ejecting blocks. Each ejecting block is embedded into the corresponding radial hole in a sliding mode. One end, located on the inner side of the outer shell, of each ejecting block is provided with an arc surface or a plane, the ejecting blocks are matched with the cam in a sliding mode, and one end, located on the outer side of the outer shell, of each ejecting block is provided with ejecting threads. In this way, only radial clamping force is exerted on a paper tube core, the two ends of the paper tube core will not deform after pressing, and therefore service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of paper processing equipment, in particular to a slitting machine unwinding and fixing device and a high-speed slitting machine. Background technique [0002] Slitting machine is a kind of mechanical equipment that cuts wide-width paper, film and other raw materials into multiple narrow-width materials. Its main mechanism usually includes slitting part, unwinding part, winding part and guide roller part. In the prior art, the unwinding part is composed of a clamping drive device, an unwinding frame, and chucks arranged at both ends of the unwinding frame. The chuck is a solid structure with a taper. Distributed pre-tightening teeth, the clamping drive device can drive the chucks at both ends to make a linear motion towards and away from each other, so as to clamp and loosen the paper core sleeved on the two chucks. However, in actual production, it often occurs that the two ends of the paper tube core are ...

Problems solved by technology

However, in actual production, it often occurs that the two ends of the paper tube core are deformed by the two chucks, causing the chucks to slip, resulting in unstable unwinding tension and affecting product quality. Cracking shortens the service life of the paper core, which undoubtedly increases the production cost
