Linear square paper tube manufacturing equipment

Abstract

The invention discloses manufacturing equipment for a linear type square paper tube. The manufacturing equipment comprises a machine base, a square die fixing frame arranged at the head end of the machine base, a square tube die which is connected with the square die fixing frame, at least one group of square tube forming devices which are matched with the square tube die, a driving device which is connected with the square tube forming devices and a cutting device for cutting a square tube, wherein the cutting device is arranged at the tail end of the machine base; the square tube forming devices are arranged on the machine base; each square tube forming device is composed of a grinding wheel for forming the square tube; each grinding wheel is matched with the square tube die; and the driving device drives each grinding wheel to rotate. The manufacturing equipment adopts the above structure, only longitudinally pushes and grinds the square tube to form without the rotation process and radial torsion stress, greatly lowers the phenomenon of generating distortion and is wider in using range.

Description

technical field [0001] The invention relates to the technical field of manufacturing equipment for paper packaging, in particular to linear square paper tube manufacturing equipment. Background technique [0002] At present, paper packaging is only widely used in plate type (such as corrugated cardboard, honeycomb cardboard, etc.) and round paper tubes, but its load-bearing capacity is poor, and it cannot replace wood at present. Although square paper tubes can meet the load-bearing requirements, due to the immature production technology, the technical parameters such as dimensional accuracy and strength cannot meet the requirements of customers. Therefore, it is especially necessary to develop this technology. [0003] There are two main ways to produce square paper tubes (that is, square tubes) at present: one is extrusion. Its technical feature is to manufacture a circular paper tube of a specific size first, and then extrude the required square paper tube by extrusion, ...
