Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing, in particular to a waist throwing and pulling device for a large bag truck. Background Art

[0002] Elastic bands are often used in the process of garment processing. For example, elastic bands are often sewn on some cuffs, trouser legs, and especially on the waistband to solve the problem of tightness of the waistband during wearing.

[0003] When sewing the elastic band, it is necessary to take out a closed elastic band and a closed elastic cloth belt, put the elastic band inside the cloth belt, and then sew the cloth belt and the elastic band together. When the elastic band is put inside the cloth belt, both need to be stretched and then sewn along the circumferential direction. When the cloth belt and the elastic band are stretched, they are generally stretched manually, which is inefficient and has a high labor cost. Summary of the invention

[0004] In view of the above problems existing in the existing elastic band sewing, the present invention aims to provide a large bag vehicle waist throwing and pulling device with high efficiency, low cost and high precision.

[0009] A first driving member, the driving member is drivingly connected to the active roller and is used to drive the active roller to rotate;

[0010] A sewing platform, the sewing platform is arranged between the active roller and the driven roller, and the sewing platform has a support plate, the top of the support plate is flush with the top of the driven roller, and the support plate has a sewing groove;

[0011] A pressing roller, the pressing roller is rotatably disposed between the sewing platform and the active roller and is located above the active roller;

[0012] The second driving member is drivingly connected to the pressing roller and is used for driving the pressing roller to move up and down.

[0013] As a further improvement and optimization of this solution, it also includes a frame, the same side ends of the active roller and the driven roller are rotatably arranged on the frame, and the sewing platform is installed on the frame.

[0014] As a further improvement and optimization of this solution, the first driving member is a driving motor, and the driving motor is installed on the frame.

[0015] As a further improvement and optimization of this solution, the second driving member is a lifting cylinder.

[0016] As a further improvement and optimization of this solution, it also includes a mounting frame, the clamping roller is rotatably arranged on the mounting frame, and the lifting cylinder is transmission-connected to the mounting frame for driving the mounting frame to lift and lower the clamping roller.

[0017] As a further improvement and optimization of this solution, the sewing groove is a waist-shaped groove.

[0018] As a further improvement and optimization of the present solution, the active roller, the driven roller and the pressure roller are all covered with rubber sleeves on their exteriors.

[0019] As a further improvement and optimization of this solution, friction patterns are provided on the rubber sleeves.

[0020] Compared with the prior art, the above technical solution has the following positive effects:

[0021] (1) In the present invention, during processing, the rubber band is sleeved onto the cloth bag and placed outside the active roller and the driven tube for stretching. The active tube rotates and drives the rubber band and the cloth belt to rotate synchronously. At the same time, the rubber band and the cloth belt are sewn circumferentially through the sewing groove. There is no need to stretch and rotate the rubber band and the cloth belt manually, thereby improving processing efficiency and reducing labor costs.

[0022] (2) In the present invention, before the rubber band and the cloth belt rotate, the pressure roller can be lowered to press them downward, thereby increasing the tension of the rubber band and the cloth belt, thereby making the synchronous rotation of the rubber band and the cloth belt more stable and improving the processing accuracy.
