Description

Technical Field

[0001] This utility model relates to an overlock machine with elastic rollers, belonging to the field of sewing machinery technology. Background Technology

[0002] An overlock machine is a device used in sewing production to overlock (or lock) the edges of fabric, and elastic bands need to be fixed to the fabric edges through overlocking.

[0003] In existing technologies, elastic bands require manual feeding or additional separate equipment for the overlocking process, which takes up a lot of space and requires separate drive power, resulting in high energy consumption. Utility Model Content

[0004] This utility model proposes an overlock machine with an elastic band trolley, which aims to overcome the above-mentioned shortcomings of the existing technology, realize the overlock machine to drive the elastic band trolley for elastic band feeding, reduce equipment space, and reduce energy consumption.

[0005] The technical solution of this utility model is as follows: an overlock machine with elastic band rollers, comprising an overlock machine body, a roller mechanism, and a segmented tape feeder. The main shaft of the overlock machine body protrudes from the machine body and is connected to the roller mechanism. The segmented tape feeder is located above the roller mechanism. The elastic band passes sequentially through the segmented tape feeder, the roller mechanism, and the overlock machine body. During operation, the feeding length of the elastic band is controlled by the segmented tape feeder, and then the main shaft of the overlock machine body drives the roller mechanism to rotate, thereby synchronously feeding the elastic band and fabric, realizing the overlock machine's drive overlock mechanism.

[0006] Preferably, the roller mechanism includes a roller, a shaft, and a gearbox. The roller is mounted on the shaft connected to one side of the gearbox, and a passive synchronizing pulley is mounted on the shaft on the other side of the gearbox. An active synchronizing pulley is mounted on the end of the main shaft that protrudes from the overlock machine body. A bushing is mounted on the main shaft outside the active synchronizing pulley, and a timing belt connects the active and passive synchronizing pulleys. When the main shaft of the overlock machine body rotates, it sequentially drives the roller to rotate through the active synchronizing pulley, timing belt, passive synchronizing pulley, shaft, gearbox, and then the shaft, thereby driving the elastic band to be fed to the overlock machine body.

[0007] The advantages of this utility model are: reasonable structural design, the rubber band trolley is powered by the main shaft of the overlock machine, which can effectively reduce the space occupied by the equipment and reduce energy consumption, and the rubber band conveying speed can be controlled by the segmented tape feeder.

Detailed Implementation

[0011] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0012] like Figure 1 , 2 As shown, an overlock machine with elastic band rollers has a structure including an overlock machine body 1, a roller mechanism 2, and a segmented tape feeder 3. The main shaft 11 of the overlock machine body 1 protrudes from the overlock machine body 1 and is connected to the roller mechanism 2 for transmission. The segmented tape feeder 3 is located above the roller mechanism 2. The elastic band passes through the segmented tape feeder 3, the roller mechanism 2, and the overlock machine body 1 in sequence.

[0013] During operation, the elastic band is fed by the segmented tape feeder 3, and then the main shaft 11 of the overlock machine body 1 drives the roller mechanism 2 to rotate, thereby driving the elastic band and the fabric to be fed synchronously, realizing the overlock machine's drive of the roller mechanism.

[0014] Specifically, the roller mechanism 2 includes a roller 21, a rotating shaft 22, and a gearbox 23. The roller 21 is mounted on the rotating shaft 22 connected to one side of the gearbox 23. A passive synchronous pulley 24 is mounted on the rotating shaft 22 on the other side of the gearbox 23. An active synchronous pulley 12 is mounted on the end of the main shaft 11 that protrudes from the body of the overlock machine 1. A bushing 13 is mounted on the main shaft 11 outside the active synchronous pulley 12. A synchronous belt 4 is connected between the active synchronous pulley 12 and the passive synchronous pulley 24.

[0015] When the main shaft 11 of the overlock machine body 1 rotates, it drives the drag wheel 21 to rotate in sequence through the active synchronous wheel 12, the synchronous belt 4, the passive synchronous wheel 24, the rotating shaft 22, the gearbox 23, and the rotating shaft 22, thereby driving the rubber band to be fed to the overlock machine body 1.
