Horizontal retracing woven bag mouth and bottom sewer

Abstract

The invention provides a horizontal retracing woven bag mouth and bottom sewer which simultaneously adopts two general woven bag bottom sewers. In order to reduce the length of equipment and bring convenience for feeding and collecting materials, the front ends of two parallel bottom sewers are provided with woven bag transferring platforms; after the mouth of the woven bag is sewn after the woven bag horizontally moves on a mouth sewer, the woven bag is horizontally sent to the transferring platforms from a discharging end and is then horizontally transferred to the feeding end of the bottom sewer from the transferring platforms; then, the woven bag horizontally enters the bottom sewer to sew the bottom mouth edge of the woven bag; and finally, the woven bag is discharged, bunched and packaged from the discharging end of the bottom sewers. Compared with the prior art, the horizontal retracing woven bag mouth and bottom sewer disclosed by the invention has the characteristics of high degree of automation, high production efficiency, no waste and the like, is reasonable to design and is convenient to operate. The parts of the sewer are made in China, so that the parts are easy to purchase, thereby greatly lowering the cost of construction of equipment and the like. Thus, the sewer has good popularization and use value.

Description

technical field [0001] The invention relates to a woven bag processing equipment, in particular to a horizontal fold-back woven bag seam bottom sewing machine. Background technique [0002] The raw material of the woven bag is woven into a continuous cylindrical blank by a knitting machine. The woven bag manufacturer then cuts the blank into a raw material with two ends open according to the length required by the user, and finally sews it into a woven bag with one end open by the bottom sewing machine. For woven bags that need seams at both ends, such as cement bags and rice bags that contain bulk materials, seams at both ends are required. Usually, the fully stitched end is called the seam bottom, and the end with only one corner of the material injection port is called the seam. In the prior art, there are two methods for seaming equipment at both ends of the cylinder material. One is to sew the mouth and bottom of the woven bag twice through a bottom sewing machine. The ...

[0002] The raw material of the woven bag is woven into a continuous cylindrical blank by a knitting machine. The woven bag manufacturer then cuts the blank into a raw material with two ends open according to the length required by the user, and finally sews it into a woven bag with one end open by the bottom sewing machine. For woven bags that need seams at both ends, such as cement bags and rice bags that contain bulk materials, seams at both ends are required. Usually, the fully stitched end is called the seam bottom, and the end with only one corner of the material injection port is called the seam. In the prior art, there are two methods for seaming equipment at both ends of the cylinder material. One is to sew the mouth and bottom of the woven bag twice through a bottom sewing machine. The disadvantage of this method is that it has low efficiency and takes up a lot of manpower; Another way is to install a sewing machine on both sides of a bottom sewing machine, and the two mouths of the raw material of the tubular woven bag enter the sewing machine at the same time for sewing and bottom sewing. Because the work of ordinary sewing machines is directional, that is, the fabric It is not possible to sew in the reverse direction on the sewing machine. The woven bag seam sewing machine of the prior art just needs a forward sewing machine and a reverse sewing machine. At present, the reverse sewing machine is not produced in China. The existing problems are low efficiency and high scrap rate. At present, there is no good solution
