Description

Technical Field

[0001] The utility model relates to the technical field of zipper sewing equipment, in particular to a material guiding device used for zipper sewing equipment. Background Art

[0002] Traditionally, a motor is used to control the rotation of a rotating shaft during zipper tape transportation. The rotating shaft contacts the zipper tape and controls the transportation of the zipper tape to the sewing machine to realize the auxiliary feeding process. After the motor of this structure is started, it is generally in an uninterrupted rotation state, which can easily cause the zipper tape to have an excessively long reserved length and become knotted, thereby affecting subsequent sewing operations. At the same time, there is no way to provide timely feedback on whether a material shortage occurs, so further improvement is needed. Summary of the invention

[0003] The utility model aims to provide a material guiding device for a zipper sewing device, which can effectively solve the problem of excessive reserved length in the feeding process and effectively sense whether the zipper tape is short of material.

[0004] In order to realize the above technical solution, the technical solution of the utility model is as follows: a material guide device for a zipper sewing device, comprising:

[0005] A base, fixed on the zipper sewing device;

[0006] A material guide assembly, which can be swingably arranged on the base, and is used to guide the feeding of the cloth and provide power at the same time;

[0007] A pressure rod is swingably disposed on one side of the base, and the material guiding assembly can drive the pressure rod to swing; and

[0008] A sensor is arranged on the same side as the pressure rod, and the pressure rod is arranged in contact with a trigger sheet on the sensor;

[0009] Wherein: when the cloth tape passes through the material guiding assembly, the sensor is in an untriggered state, otherwise it is in a triggered state.

[0010] Furthermore, the base includes a bent bracket; a positioning guide wheel is rotatably provided on the bracket, and the positioning guide wheel is adapted to one end of the material guiding assembly.

[0011] Furthermore, the positioning guide wheel is in the shape of a rotating body; the positioning guide wheel is contracted inwardly along the axis from both ends, and a thin disk expanding radially outward is provided at the intersection; the thin disk is inserted at one end of the material guide component.

[0012] Furthermore, the material assembly includes a rotating shaft rotatably arranged on the bent bracket; a material guide plate is welded on the rotating shaft; when the cloth is not passing through, one end of the material guide plate is in linear contact with the positioning guide wheel while the other end pushes the pressure rod downward to trigger the sensor.

[0013] Furthermore, the material guide plate includes a base; one end of the base is bent outward and provided with a trigger portion; the other end of the base is inclined outward and provided with a first material guide portion and a second material guide portion; a rotating channel is provided adjacent to the first material guide portion and the second material guide portion; and the thin plate can be rolled on the rotating channel.

[0014] Furthermore, the pressure rod comprises a pressure rod seat rotatably arranged on the bent bracket; a pressure rod element is screwed onto the pressure rod seat; and an adapter block element is adjustably screwed onto one end of the pressure rod element.

[0015] Furthermore, the sensor is a proximity switch.

[0016] Compared with the prior art, the utility model has the following beneficial effects: 1) The utility model guides the zipper tape by setting a material guide assembly, and cooperates with the positioning guide wheel on the base that is set to shrink inward along the axis from both ends, and a thin disk that expands radially outward is provided at the intersection to press and position the zipper tape. Once it is too long, the feeding end can always be guaranteed to be flat and not knotted, and the normal conveying process of the tape is maintained. The overall practicality is strong and has great market promotion value;

[0017] 2) After the cloth belt of the utility model is used up, the trigger part will move downward under the action of gravity, and then the trigger part will squeeze the adapter block element to swing, thereby triggering the sensor to be squeezed, and then the signal is transmitted to complete the control of the motor;

[0018] 3) The utility model has a simple structure, saves costs and has high working efficiency, avoids the occurrence of knots, has good product quality, high yield rate, and high structural utilization rate. BRIEF DESCRIPTION OF THE DRAWINGS
