A filter bag pinhole gluing device and gluing method thereof

Abstract

The invention discloses a filter-bag needle eye gluing device. The device comprises a cover shell, an electric sliding frame; a heat supply device is arranged on the inner wall of the cover shell andat least two electric control rolling shafts; the electric sliding frame is arranged above the cover shell, the electric sliding frame is connected with the top of the cover shell through a first lifting unit, a filter-bag inlet and a filter-bag outlet are formed in two opposite end surfaces of the cover shell correspondingly, the filter-bag inlet and the filter-bag outlet are horizontally arranged, the width of the filter-bag inlet and the width of the filter-bag outlet each are matched with the width of the filter bag, and the filter bag enters cover shell from the filter-bag inlet, and getsout of the cover shell from the filter-bag outlet; all the electric control rolling shafts are parallel to the filter-bag inlet, and are evenly distributed at the two ends, corresponding to the filter-bag inlet and the filter-bag outlet, in the cover shell, and the two ends of each electric control rolling shaft are connected with the inner wall of the cover shell correspondingly. According to the filter-bag needle eye gluing device, the filter bags at different stations can be conveniently dried, moreover, the drying process is completely sealed, and the leakage of poisonous and harmful gasis avoided.

Description

technical field [0001] The invention belongs to the field of mechanical equipment or automation equipment, and in particular relates to a filter bag pinhole gluing device. Background technique [0002] The filter bag is a filter medium made of natural fibers or synthetic fibers. Commonly used materials are cotton, hemp, wool, cocoon silk, asbestos fibers, glass fibers and some synthetic fibers, such as cotton canvas, twill and wool fabric. woolen cloth etc. In a broad sense, filter bags also include metal mesh or filter screens. During the production process of the filter bag, it needs to go through many processes, including the process of applying glue to the pinhole of the filter bag. [0003] In the past, the glue coating and sealing of the filter bag body used a glue dispenser combined with manual control to apply silica gel on the filter bag stitches. The principle is to use the pressure barrel to send the glue in the glue barrel to the glue head. The glue head appli...

AI Technical Summary

Problems solved by technology

[0005] First, the glue applicator is not designed according to the outline of the seam of the filter bag, and the edges of the glue applied are not neat and unsightly;

[0006] Second, the applied glue protrudes from the stitching surface of the filter bag, the amount of glue used is large and the cost is high;

[0007] Third, the stitching of the filter bag moves left and right, and the glue head must be aligned with the stitching manually, which is difficult to ensure the accuracy of the position;

[0008] Fourth, the running speed of the dispensing machine is unstable, but the glue output speed is constant. When the dispensing machine is running slowly, the amount of glue applied on the stitches will be more, otherwise it will be less, and the delivery volume will be very uneven;

[0009] Fifth, every time the glue in the glue barrel is used up, the dispenser needs to be stopped to add glue to the glue barrel, which is a waste of time

[0010] Sixth, the entire gluing process is in an open environment, and the glue will emit toxic and harmful gases, which will bring great hidden dangers to the health of workers
