A Floating Cutter Head That Can Automatically Find the Longitudinal Slit of Towel Blank

Abstract

The invention discloses a floating tool bit capable of automatically finding longitudinal cut gaps of towel blanks and belongs to the technical field of cutting tools. According to the technical scheme, the floating tool bit comprises a mechanical portion and a control portion, wherein the control portion comprises an intelligent controller and a gap finding sensor. The gap finding sensor comprises a light emitter and a light receiver, wherein the light emitter is located under the towel blanks, the light receiver is located above the towel blanks, the light emitter and the light receiver correspond to each other, the light receiver comprises multiple photoelectric tubes linearly and evenly arranged in the direction parallel to a cloth guide roller, the output end of each photoelectric tube is connected with an input port of the intelligent controller through a signal conditioning unit, and a housing of the light receiver is fixed to a floating base through a sensor support. The control signal output end of the intelligent controller is connected with a floating base drive device. The floating tool bit judges the positions of the longitudinal cut gaps according to the longitudinal cut gaps of the towel blanks and the difference of the light-transmitting rates on two sides, can accurately control cutting positions, can achieve automatic tool setting when a blade passes by line connecting ends due to the wide detection range of the gap finding sensor, and accordingly production efficiency is remarkably improved.

Description

technical field [0001] The invention relates to a floating cutter head used for longitudinal cutting equipment for towel blanks, which can automatically align with longitudinal slits of towel blanks, and belongs to the technical field of textiles. Background technique [0002] The production process of towels (including cotton towels and microfiber towels) generally includes processes such as weaving, printing and dyeing, washing, shaping, and finished products. figure 1 The large towel blanks shown are cut into small pieces of blank towels along the longitudinal slit and cross-cut slit, and then the cut blank towels are locked or hemmed, and sometimes a trademark or washing label is added if necessary. The traditional cutting method is to use manual methods for slitting and cross-cutting (put the towel blanks on the case and stack them into a pile, and cut them with vibrating scissors), which not only increases the labor intensity of workers, but also reduces production eff...

Problems solved by technology

[0005] 1. The C-type optical fiber sensor is used to detect the longitudinal slit. Since the size of the towel is uncontrollable, when the longitudinal slit is misaligned when passing through the transverse slit, automatic knife setting after the joint (transverse slit) cannot be realized. Therefore, After each joint, the operator needs to re-set the knife, which greatly reduces the production efficiency
