Flexible and variable track device, spreader spreading wheel and spreader

Abstract

The invention provides a flexible variable rail device, a fabric spreading wheel of a fabric spreading machine and the fabric spreading machine. The fabric spreading machine comprises a driving assembly and a rail assembly, wherein the driving assembly comprises a driving component and a sliding assembly, the sliding assembly comprises a main slider and a plurality of auxiliary sliders, the main slider is in transmission connection with the driving component and is driven by the driving component to make linear reciprocating movement, all auxiliary sliders are connected through a variable-shape transmission component, and the transmission component is connected with the main slider; the rail assembly comprises a plurality of movable blocks, all movable blocks are distributed in the peripheral direction, forming an annular rail, part of movable blocks are located and connected in the axial reaction, and the rest of movable blocks are in one-to-one correspondence connection with the auxiliary sliders; and when the main slider is driven by the driving component to make linear movement, all auxiliary sliders are driven by the transmission component to make linear movement, the positionof each movable block in the rest of movable blocks in the axial direction is accordingly changed, and in this way, the change of the contour of the annular rail is realized. The contour of the annular rail can be adjusted according to the elasticity of fabric, fabric spreading width is better adjusted, and the fabric spreading effect is improved.

Description

technical field [0001] The invention relates to the technical field of spreading machines, in particular to a flexible variable track device, spreading wheels of the spreading machine and the spreading machine. Background technique [0002] In the modern textile industry, cloth spreading machines are widely used, mainly for pulling out the entire roll of cloth to an appropriate length and laying it flat, then cutting, and cutting into various standard cloths according to specific needs. And in order to lay the stretched cloth on the cutting bed evenly, the spreading wheel structure is usually set on the spreading machine to solve this problem. The structure of the spreading wheel is generally composed of a lifting wall, a cam, a roller, a blade and a blade contact. Its working principle is as follows: the roller is rotatably connected between the two lifting walls, and the blade is set The contact is stuck in the annular groove of the cam, and the roller drives the blade to...
