[0002] The applicant has previously applied for a Chinese invention patent with publication number CN114960047A for a double-station sewing arrangement structure for elastic bands, whose main structure includes a feeding mechanism, a rotary feeding mechanism, a first elastic band sewing mechanism, and a second elastic band sewing mechanism, both of which are used for sewing elastic bands; it also includes a pulling mechanism, which is used to pull the elastic band in the feeding mechanism to the rotary feeding mechanism, and the rotary feeding mechanism is used to rotate, fold, and dock the two ends of the elastic band and transport them one by one to the first elastic band sewing mechanism and the second elastic band sewing mechanism.

[0003] The rubber band machine with the above structure has a high processing efficiency, but in actual use, it is found that since the arrangement angle between the first rubber band sewing mechanism and the second rubber band sewing mechanism in the double-station sewing arrangement structure of the above structure is 90 degrees, the rotating feeding mechanism needs to produce a large angle of rotation when transporting the rubber band to be processed, and the material transmission stability is poor. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a double-end flat joint device for a rubber band, which maximizes the stability of material transmission while ensuring processing efficiency.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] A double-end flat joint device for elastic bands comprises a feeding mechanism, a pulling mechanism, a first elastic band sewing mechanism and a second elastic band sewing mechanism, wherein the pulling mechanism is used to pull the elastic band in the feeding mechanism into the turning mechanism, and the first elastic band sewing mechanism and the second elastic band sewing mechanism are both used to sew the elastic bands;

The transfer mechanism is used to transfer the flipped, folded, and docked elastic bands in the turning mechanism to the first elastic band sewing mechanism and the second elastic band sewing mechanism one by one.

[0010] Through the above technical scheme, the pulling mechanism pulls the rubber band raw material in the feeding mechanism to the turning mechanism for flipping, folding and docking, and the transfer mechanism transfers the flipped and folded rubber band in a straight line up and down to the first rubber band sewing mechanism and the second rubber band sewing mechanism for corresponding sewing processes; the structural characteristics of the above device are that the material processing efficiency is high, the transfer mechanism does not need to rotate circumferentially, the rubber band raw material can be transferred and sewn, and the material transmission stability is greatly improved.

[0011] Preferably, the transfer mechanism includes a main transfer drive unit, a vertical transfer drive unit, a transverse transfer drive unit, and a transfer clamping unit. The vertical transfer drive unit is used to drive the transverse transfer drive unit and the transfer clamping unit to perform vertical lifting movements. The transverse transfer drive unit is used to drive the transfer clamping unit to move toward or away from the side of the turning mechanism. The transfer clamping unit is used to clamp the elastic band that has been flipped, folded, and docked. The main transfer drive unit is used to drive the vertical transfer drive unit to move back and forth between the first elastic sewing mechanism, the turning mechanism, and the second elastic sewing mechanism.

[0012] Through the above technical scheme, during the actual transfer process, the main transfer drive unit drives the transfer clamping unit to the side of the material turning mechanism, the transverse transfer drive unit drives the transfer clamping unit to move toward the side close to the material turning mechanism, and then the transfer clamping unit clamps the folded rubber band, and the transverse transfer drive unit drives the transfer clamping unit to move away from the material turning mechanism.

Then, the first pushing cylinder drives the first pushing plate to move, and the first pushing plate can apply a thrust to the end of the rubber band, so that the end of the rubber band that has been flipped, folded and docked can be aligned with higher accuracy.
