Embodiment Construction

[0024] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations.

[0025] Such as Figure 1-3 As shown, this embodiment provides a continuous stretching and slitting mechanism for raw material tape, which includes a fixed plate 1 and a heating and stretching assembly 2 and a cooling assembly 5 mounted on the fixing plate 1. The heating and stretching assembly 2 is connected to the A pre-tightening shaft 3 and an adjusting shaft 4 are arranged between the cooling components 5; the adjusting shaft 4 rotates around the axis of the pre-tightening shaft 3, and the end connecting the adjusting shaft 4 and the pre-tightening shaft 3 is provided with The coil spring 9 and the elastic force adjusting device 8 make the adjusting shaft 4 always have a movement tendency of winding the raw material belt on the rotating shaft of the pre-tensioning shaft 3. When the heating and stretching assembly 2 stretches...

Abstract

The invention discloses a mechanism for continuously stretching and slitting a raw material belt, and belongs to the field of slitting mechanisms. The mechanism for continuously stretching and slitting the raw material belt comprises a fixed plate, a heating and stretching assembly and a cooling assembly, wherein the heating and stretching assembly and the cooling assembly are installed on the fixed plate; a pre-tightening rotating shaft and an adjusting rotating shaft are arranged between the heating and stretching assembly and the cooling assembly; the adjusting rotating shaft rotates aroundthe axis of the pre-tightening rotating shaft; and a coil spring and an elastic force adjusting device are arranged at the end part, connected with the pre-tightening rotating shaft, of the adjustingrotating shaft, so that the adjusting rotating shaft always has a motion trend of winding the raw material belt on the pre-tightening rotating shaft. According to the mechanism for continuously stretching and slitting the raw material belt, the raw material belt is pulled to rotate and be wound around the pre-tightening rotating shaft through the adjusting rotating shaft, so that the tensioning force of the raw material belt is changed, and cutting is neat when the raw material belt is slit.

Description

Technical field [0001] The invention relates to the field of slitting machines, in particular to a continuous stretching slitting mechanism for raw material belts. Background technique [0002] The existing slitting equipment that can produce PTFE raw tape has many shortcomings. The existing raw tape stretching machine is a long-distance segmented equipment, and the grease path is short, resulting in insufficient degreasing time, which seriously affects product quality; The shaping part is only 1 meter long, and the belt shaping time is not enough. The shrinkage rate of the belt is 5%-10%. At the same time, the deformation of the belt causes loss due to the shrinkage; independent heating in sections, high energy consumption; long-distance one-step pulling of the raw material belt Stretching, it is easy to break the belt, causing large loss, and the width and thickness of the stretched product are uneven; and the number of stretched belts is small, and the production efficiency is...
