Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0025] Such as Figure 1 to Figure 6 As shown, to achieve the purpose of folding in the two sides of the tubular fabric 13, the tubular fabric 13 needs to be placed on an object in a relaxed state, and can be tightened and fixed to facilitate the next step of manipulator folding. The structure that the preferred tubular fabric is entangled and tightened is two wide arms, and the preferred shape of the wide arms is a semi-cylindrical body. The semicircular stainless steel thin-walled pipe 12 is bonded on the semicircular arc surface of the wide arm, so that the manipulator can stretch into the pipe wall when flanging, thereby completing the flanging work.

[0026] During work, the preferred movement mode of the two stretching arms is parallel opening and closing. When closed, install and take out the tubular fabric; when opened, tighten and...

Abstract

The invention discloses an edge-folding device for tubular fabric, so as to solve the problem that the product is poor in quality as edge-folding is carried out manually. The edge-folding device for tubular fabric comprises a wide-stretching unit and an edge-folding unit; the wide-stretching unit is used for sheathing the tubular fabric in a loose state on the wide-stretching unit and tightening and fixing the tubular fabric; the edge-folding unit is used for folding the edge of the tubular fabric fixed on the wide-stretching unit inwardly; the wide-stretching unit at least comprises two wide-stretching arms, a wall plate and a wide-stretching control assembly; the wide-stretching control assembly comprises a lead screw, a nut, a rocker arm and a handle; the edge-folding unit at least comprises a bending plate, a supporting foot, a supporting foot seat, a pull rod, a pull rod seat, a shaft, a shaft seat, a backstop assembly and an edge-folding control assembly; and the edge-folding control assembly comprises a pull plate, a spring, a manual rod and a manual rod seat. The edge-folding device for tubular fabric is reasonable in structure, convenient in use, low in cost and is applied to edge folding after the tubular fabric is cut.

Description

technical field [0001] The invention relates to a hemming device for a tubular fabric. Background technique [0002] Tubular fabrics (such as ribbons) are usually produced in one long, large length of tape, which is then divided into smaller pieces for use. When cutting into small sections, the cutting edge is usually rough, which is easy to fall off and be damaged, so it is necessary to fold the rough edge into the tube. [0003] The existing hemming process is completed by manual operation, which causes more serious problems such as irregularity and inaccurate size, and it is difficult to guarantee the quality of the product. Contents of the invention [0004] In order to overcome the above defects, the present invention provides a hemming device for tubular fabrics with better hemming effect. [0005] In order to achieve the above object, the present invention provides a hemming device for tubular fabrics, the device includes a stretching unit and a hemming unit: [...
