Embodiment 1

[0018] Embodiment 1, It is the basic embodiment of the present invention. like figure 1 , 2 , Shown in 3, a kind of industrial sewing machine feeding device, it comprises frame 1, and this frame 1 is equipped with air gripper support 2, ejector rod support 3, pneumatic system 4 and hot knife support 5, roller assembly 6 and straight line The slide rail 10; the feeding is to send the nylon belt; the frame 1 is installed on the industrial sewing machine platen; the roller assembly 6 includes a spring for clamping the nylon belt, and the roller assembly 6 is installed on the frame 1 , used to control the pre-tightening force of the nylon belt by adjusting the compressed length of the spring; the pneumatic system 4 includes a plurality of air claws 4.1 and 3 cylinders, which are respectively No. I cylinder 4.2, No. II cylinder 4.3 and No. III cylinder 4.4 and A plurality of solenoid valves, as well as a valve island, a filter pressure reducing valve and a pneumatic box; among ...

Embodiment 2

[0019] Embodiment 2, It is an optimized technical solution, and the difference from claim 1 is: as figure 1 , figure 2 and image 3 As shown, the pneumatic system 4 with 3 cylinders has 9 air grippers 4.1, and 12 solenoid valves. 3 cylinders, respectively No. 1 cylinder 4.2, No. 2 cylinder 4.3 and No. 3 cylinder 4.4; there are also valve islands, filter pressure reducing valves and pneumatic boxes.

[0020] Taking embodiment 2 as an example, it is based on the actions of No. I cylinder 4.2, No. II cylinder 4.3, and No. III cylinder 4.4 that the working principle of the present invention and the working process are as follows:

[0021] 1. The initial state of the cylinder: First, the nine air claws 4.1 are opened synchronously, and then the piston of the No. 1 cylinder 4.2 is retracted, driving the movement of the air claw 4.1 to a distance of 350mm; the piston of the No. Ⅱ cylinder 4.3 is stretched out, making the nylon belt U Type, the stroke is 400mm; the piston of No....

Abstract

The invention relates to a feeding device for an industrial sewing machine. The feeding device is particularly applicable to parallelly conveying a plurality of nylon tapes to the multi-needle industrial sewing machine for sewing the nylon tapes on a canvas. The feeding device comprises a frame, a valve terminal, a filtering pressure reducing valve and a pneumatic box, a pneumatic gripper support, an ejector rod support, a pneumatic system, a hot knife support, a rolling shaft component and a linear sliding rail are mounted on the frame, the pneumatic system comprises a plurality of pneumatic grippers, three cylinders and a plurality of electromagnetic valves, the pneumatic grippers are mounted on the pneumatic gripper support, a plurality of ejector rods are mounted on the ejector rod support and used for ejecting the straightened nylon tapes into 'U' shapes, and a plurality of hot knives are mounted on the hot knife support. The feeding device has the advantages that the feeding device is time-saving, labor-saving, high in efficiency, low in cost, reliable in quality, simple and compact in structure, low in manufacturing cost, convenient to use and maintain and the like, and the nylon tapes can be integrally conveyed, folded, cut and sewn.

Description

technical field [0001] The invention relates to a feeding device for an industrial sewing machine, which is particularly suitable for conveying several nylon belts in parallel to a multi-needle industrial sewing machine for sewing on canvas, and belongs to the technical field of textile machinery. Background technique [0002] In the flood control work of rivers in our country, there is a flood control method: use a canvas with a width of 4.2m, and sew several nylon belts with a length of 950mm and a width of 12mm on it, which are used to bind cement columns and lay them along the embankment to reinforce the river embankment. Usually there are 9 nylon strips with a spacing of 500mm, and the sewing machine has 9 needles corresponding to it. In order to prevent each series of nylon straps from being stitched by adjacent left and right needles, firstly place the nylon straps on a plane in a "U" shape, then sew the two layers together, and then cut the nylon straps with a hot k...
