Automatic seaming device for cone yarn woven bag

Abstract

The invention discloses an automatic seaming device for a cone yarn woven bag, which belongs to the technical field of packaging seaming and comprises a device body, an upper frame, a first frame, a second frame, a lower frame, an upper clamping plate cylinder, a lower clamping plate cylinder, a tensioning cylinder, a baffle cylinder, an upper roller cylinder and a lower roller cylinder. A supporting seat is arranged on the inner side of the first frame and is fixedly connected with the first cross beam and the second cross beam; the piston rod end of the upper clamping plate cylinder is fixed above the first cross beam; one end of an upper clamping plate is connected below the first cross beam, and one end of a lower clamping plate is connected above the second cross beam; the lower side of the first frame is fixedly connected with a tensioning cylinder; the piston rod end of the baffle air cylinder is fixedly connected with a baffle; the edge of the second frame is connected with the sewing machine assembly; an upper roller cylinder and a lower roller cylinder are arranged on the inner side of the second frame. According to the invention, the reserved length of the bag opening can reach the shortest length in the industry, and meanwhile, the package attractiveness is ensured.

Description

Technical field [0001] The present invention belongs to the field of packaging seam technology, particularly relates to a kind of automatic sewing device for cylinder yarn woven bags. Background [0002] After the cylinder yarn bag is completed, the woven bag needs to be automatically sewn. In the existing sewing device, affected by the size of the cavity of the existing sewing machine, the distance between the bag mouth clamping structure and the baffle used to block the cylinder yarn is too large, about 70 mm, at this time, the slit mouth needs to be reserved for a long distance, otherwise it will cause sewing can not be grasped, so the prior art has the problem of causing the bag mouth to be too long when sewing. Contents of the Invention [0003] In order to solve the above problems, the present invention proposes a cylinder yarn woven bag automatic sewing device, while ensuring the shortest bag reservation while automatically sewing the woven bag. [0004] The technical em...

Problems solved by technology

In the existing seaming device, affected by the size of the cavity of the existing sewing machine, the distance between the clamping structure of the bag mouth and the baffle for blocking the bobbin is too large, about 70 mm, and the seam is reserved at this time. The opening of the bag needs a long distance, otherwise it will not be able to be grasped during sewing, so the existing technology has the problem that the opening of the bag is too long when sewing
