Technical Field

[0001] This utility model relates to the field of automatic sewing technology, and in particular to a triangular plate stabilization and positioning device. Background Technology

[0002] In the existing automatic sewing process for triangular pieces, the triangular pieces may shift during placement due to machine vibration and other factors. Furthermore, the triangular pieces are prone to displacement during folding and hemming, resulting in uneven folding and inconsistent sewing quality. Utility Model Content

[0003] In view of this, in order to solve the defects and shortcomings of the existing technology, a device for stabilizing and positioning triangular pieces is provided to improve the stability of triangular piece sewing and further enhance the sewing quality.

[0004] To address the problems existing in the prior art, the technical solution of this utility model is: a triangular plate stabilizing and positioning device, characterized in that it includes a folded plate, the folded plate is provided with threaded holes arranged in a triangle, each threaded hole is provided with an adjusting valve, each adjusting valve is connected to a vacuum generator, and the upper surface of the folded plate is provided with a positioning sensor, the positioning sensor is controlled by a PLC controller.

[0005] Furthermore, the vacuum generator is connected to the regulating valve via a gas pipe.

[0006] Furthermore, the edges of each threaded hole are chamfered.

[0007] Compared with the prior art, the advantages of this utility model are as follows:

[0008] 1) This utility model is used for the stable positioning of triangular pieces in the fully automatic folding and sewing process of triangular pieces. The controller controls the vacuum generator to form a negative pressure on the folding plate, which adsorbs the triangular pieces placed on the folding plate, so that the triangular pieces are stably positioned.

[0009] 2) The structure of this utility model can solve the problem of triangle piece displacement in the fully automatic folding and sewing process, which greatly improves the stability of the triangle piece folding effect and reduces the scrap rate. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] This embodiment provides a device for stabilizing and positioning triangular pieces, such as... Figure 1 As shown, the device includes a folding plate, a regulating valve, a vacuum generator, a PLC controller 6, and a positioning sensor. The folding plate has three threaded holes 3 arranged in a triangular pattern with chamfered edges. Each threaded hole 3 is connected to a regulating valve 2. The vacuum generator 5 is connected to each regulating valve 2 via an air pipe. The positioning sensor 4 is located above the folding plate 1. The PLC controller 6 is electrically connected to the positioning sensor 4 and controls the vacuum generator 4 to create a negative pressure on the folding plate 1, which attracts the triangular pieces placed on the folding plate 1, thus stabilizing the triangular pieces.

[0015] like Figure 2 As shown, the steps of a control method for a triangular plate stabilizing and positioning device are as follows:

[0016] The positioning detector detects the signal that the triangular piece on the folding plate is in place, and when the signal is detected, the triangular piece sends the signal to the controller.

[0017] The controller activates the vacuum generator, creating negative pressure on the folded plate to attract the triangular pieces.

[0018] After the folding plate is flipped into place, the vacuum generator is turned off, thus stopping the adsorption effect of the folding plate on the triangular pieces.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. It should be noted that any improvements and modifications made by those skilled in the art without departing from the principle of the present utility model should be considered as within the scope of protection of the present utility model.
