Adhesive tape type fabric sucker for industrial sewing machine

Abstract

The invention relates to an adhesive tape type fabric sucker for an industrial sewing machine. The sucker comprises a shell, wherein a cylinder is vertically installed in the shell, a telescopic ejector rod of the cylinder is fixedly connected with an adhesive tape rotation mechanism, and the adhesive tape rotation mechanism moves up and down along guiding grooves in the two sides of the shell under the driving of the cylinder; a one-way wheel and a driven wheel are fixed to the adhesive tape rotation mechanism, the one-way wheel is provided with a rocker arm, a limiting component is arranged on the shell, and the rocker arm is located in the vertical space of the limiting component; adhesive tape is wound around the one-way wheel and the driven wheel, the inner side of the adhesive tape is attached to a sucker body in a sliding mode, and the sucker body is connected to the lower portion of the adhesive tape rotation mechanism; when the rotation mechanism 4 is lifted up, fabric disengages from the adhesive tape to fall into a required area under the relatively outward action force of the shell, so that disengagement is achieved; meanwhile, the rocker arm rotates in the forward direction under the action of the limiting component, and the one-way wheel rotates in the forward direction to drive the adhesive tape to advance by the length of one sucker body; when the rotation mechanism is pressed downwards, the rocker arm rotates in the reverse direction freely under the action of the limiting component to conduct adsorption, and the one-way wheel restores freely in the reverse direction.

Description

technical field [0001] The invention relates to an industrial sewing machine cloth suction cup, in particular to a tape-type cloth suction cup for an industrial sewing machine, which belongs to the technical field of industrial sewing machine suction cups. Background technique [0002] The cloth grab suction cups of the existing industrial sewing machines generally have two forms. One is to use a non-contact suction cup. The bottom of the suction cup is blown obliquely to generate a local negative pressure, thereby suspending and adsorbing the cloth. However, when the suction cup moves laterally The cloth and the suction cup are prone to relative displacement, so the cloth cannot be accurately sent to the position to be processed; the other is the pure vacuum suction cup type, but the vacuum suction cup type is difficult to control the suction force because it directly vacuums the cloth. For some fabrics, it either cannot absorb or absorbs multiple pieces of fabric at one ti...
