Technical Field

[0001] The utility model relates to the technical field of overlock machines, in particular to a feeding structure of an overlock machine. Background Art

[0002] The overlock machine is a sewing machine used in the production and processing of fabrics. It is used to lock the edges of the fabric to prevent the silk threads at the edges of the fabric from dispersing due to their high hardness. At this time, the overlock machine can process the edges of the fabric. At the same time, the overlock machine will be used in conjunction with the feeding structure to continuously process the fabric.

[0003] A servo motor is fixed at one end of the feed frame, and the output end of the servo motor is fixedly connected to the feed roller. A buffer area is provided at the bottom inner end of the feed frame, and the feed roller and the buffer area are located on the top side of the workbench. When feeding the overlock machine, the fabric is first placed in the buffer area. During the conveying process, the fabric is pulled out from the inside of the buffer area. At this time, the fabric does not need to overcome the friction between the roller and the feed frame. At the same time, the buffer area is located on the top side of the workbench, which can prevent the fabric from being dragged by its own weight, thereby reducing the deformation of the elastic fabric and ensuring that the processing quality of the overlock machine will not decline.

During the use of the feeding structure, multiple motors are set to drive multiple rollers to rotate respectively, thereby conveying the cloth to move. During use, multiple motors increase the overall power consumption of the feeding structure, resulting in an increase in the production and processing costs of the cloth, and thus a feeding structure of a overlock machine is proposed.

[0026] Working principle: The overlocking machine is a sewing machine used in the production and processing of fabrics, that is, it performs lock-edge processing on the fabric to prevent the silk threads at the edge seams of the fabric from being dispersed due to their own high hardness. At this time, the overlocking machine can process the edge seams, and at the same time, the overlocking machine will cooperate with the feeding structure to continuously process the fabric. During the use of the existing feeding structure, multiple motors are set to drive multiple rollers to rotate respectively, thereby conveying the fabric to move. During use, multiple motors increase the overall power consumption of the feeding structure, resulting in an increase in the production and processing cost of the fabric. In order to solve this problem, a conveying mechanism and an adjusting mechanism are set, and the insertion rod 21 is pulled out. With the cooperation of the slider 17, the limit roller 15 is pushed up and down and slides along the slide groove 16. After the limit seat 14 is adjusted to the required width, the limit roller 15 is moved to the appropriate position according to the thickness of the fabric.

At this time, the servo motor 2 is controlled to drive the conveyor belt 5 to move under the cooperation of the driving roller 3 and the driven roller 4. At this time, the cloth body 101 can be placed on the surface of the conveyor belt 5 and moved smoothly under the cooperation of the auxiliary roller 6. At the same time, the air pump 9 is controlled to extract the air inside the shell 8 so that it can cooperate with the through hole 51 to adsorb and fix the cloth on the surface of the conveyor belt 5 to prevent folding or elastic deformation during transportation. After the cloth body 101 is output from the other end of the conveyor belt 5, it is inserted between the output roller 13 and the limiting roller 15, and the driving motor 12 is controlled to drive the output roller 13 to rotate. The cloth sleeved on the output roller 13 is output from one end of the fixed plate 11 to the processing position of the overlocking machine, thereby performing overlocking processing on it, solving the problem of high conveying cost of the existing feeding structure.
