Assistance mechanism for bottom seaming machine of woven bag

Abstract

The invention discloses an assistance mechanism for a bottom seaming machine of a woven bag, comprising a stander, wherein a first ring-shaped conveyor belt is arranged on the stander, the stander is provided with an edge coiling device at the outer side of the first conveyor belt, the stander is provided with a synchronous conveying mechanism at the lower side of the edge coiling device, the conveying speed and the conveying direction of the synchronous conveying mechanism are matched with those of the first conveyor belt. The assistance mechanism has the beneficial effects that the conveying speed lost by coiling the edge at the bottom of the woven bag is effectively compensated, so that the woven bag is tidy in edge coiling, and good in sewing quality, the wrinkles can be avoided when the woven bag is conveyed, the sewing speed of the bottom seaming machine can be improved in multiples, and the original quality bottleneck of the woven bag can be broken through, so that about sixty woven bags can be seamed pre minute; and the bottom seaming machine is smooth to run, so that the number of the production line operator can be reduced from four to one, therefore, the assistance mechanism has considerable economic benefit in the current market that the labor cost is constantly improved.

Description

technical field [0001] The present invention relates to an auxiliary conveying device, more specifically, the present invention relates to an assisting mechanism specially used for a woven bag bottom sewing machine. Background technique [0002] During the production process of the woven bag, the bottom of the woven bag needs to be hemmed by a crimping device before being sewn. The friction force generated by the relative sliding between the crimping device and the woven bag increases with the increase of the sliding speed. When the relative sliding speed reaches a certain value, the frictional force will block the transmission of the woven bag on the bottom sewing machine equipment. The effect is very obvious. It will cause the woven bag to deviate during the transmission process. One end of the woven bag is wide and the other end is narrow. When it is serious, there is sewing thread at the wide end of the woven bag, and there is no sewing thread at the narrow end of the w...

Problems solved by technology

The friction force generated by the relative sliding between the crimping device and the woven bag increases with the increase of the sliding speed. When the relative sliding speed reaches a certain value, the frictional force will block the transmission of the woven bag on the bottom sewing machine equipment. The effect is very obvious. It will cause the woven bag to deviate during the transmission process. One end of the woven bag is wide and the other end is narrow. When it is serious, there is sewing thread at the wide end of the woven bag, and there is no sewing thread at the narrow end of the woven bag, which needs to be reworked; what is more serious is that the woven bag is wrinkled during the hemming, and the wrinkle is in the When passing through the sewing machine, it will be caught by the pressing plate of the sewing machine. Not only will the woven bag be broken, but it will also cause damage to the sewing machine, affecting the service life of the sewing machine, and the entire production line will also be forced to stop for repairs.
