A conveyor belt deviation correcting device for a stenter setting machine

Abstract

The invention discloses a correcting device for a conveying belt of a tentering setting machine. The correcting device comprises a machine frame, a cloth feeding roller, a transmission roller and the conveying belt. The cloth feeding roller and the transmission roller are sleeved with the conveying belt. The left side and the right side of the conveying belt are provided with a left deflection inductor and a right deflection inductor respectively. A pair of correcting racks are fixed to the upper end faces of the portions, on one side of the left deflection inductor and on one side of the right deflection inductor, of the conveying belt. A correcting mechanism is arranged above the correcting racks and comprises a fixing plate, a pair of correcting cylinders, a correcting frame, a correcting motor, a correcting spline shaft and a correcting gear. The correcting frame comprises a transverse plate and a pair of vertical plates fixed to the two ends of the transverse plate. One ends of piston rods of the pair of correcting cylinders are fixedly connected to the two ends of the top face of the transverse plate respectively. The two ends of the correcting spline shaft are hinged to the pair of vertical plates respectively. An output shaft of the correcting motor is fixedly connected with the correcting spline shaft which is sleeved with the correcting gear. By means of the correcting device, the deflected conveying belt can be automatically corrected, and therefore normal running of the tentering setting machine is guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of a stenter setting machine, in particular to a conveyor belt deviation correcting device of a dust removal device for a stenter setting machine. Background technique: [0002] Stenter setting machine is an indispensable and main equipment in the field of fabric printing and dyeing. It is a necessary equipment for finishing fabrics and improving the mechanical properties of fabrics. During the process of scouring, bleaching and printing and dyeing, the fabric is subjected to many times of mechanical radial tension, causing the fabric to elongate in the radial direction and shrink in the weft direction, resulting in phenomena such as uneven width, uneven selvedge, and skewed weft yarns. In order to overcome the above shortcomings, the fabric must be tenter finished. Stenter finishing is based on the plasticity of cotton fibers in a wet state. During the drying process, the state of the warp and weft yarns ...

AI Technical Summary

Problems solved by technology

[0003] The fabric enters the drying equipment through the cloth feeding frame. The cloth feeding roller and the driving roller are installed on the cloth feeding frame. The conveyor belt is tensioned on the cloth feeding roller and the driving roller. The dust suction mechanism sucks away the fluff on the conveyor belt. Due to the installation error of the machine and the manufacturing error of the conveyor belt itself, the conveyor belt is prone to deviation after running for a certain period of time, which affects the production efficiency of the stenter setting machine.

The traditional solution is to set baffles on both sides of the conveyor belt. When the conveyor belt deviates from the normal position, the conveyor belt will touch the baffle and be blocked. However, this method of correcting deviation has the following defects: Friction due to contact will easily cause wear and tear on the conveyor belt and the baffle for a long time, and the equipment will be easily damaged; and the baffle can only prevent the conveyor belt from shifting, but cannot correct the shifted conveyor belt to the correct position above, it is necessary to improve
