Description

Automatic blanking machine for producing braided straps

Technical Field

The utility model belongs to the technical field of the meshbelt production facility, especially, relate to an automatic blanking machine for braid over braid production.

Background

The woven belt is a narrow fabric or tubular fabric made of various yarns as raw materials, has various varieties, and is widely used in various industrial departments such as clothes, shoe materials, cases, industry, agriculture, military needs, transportation and the like. The woven belt is processed and produced by adopting an automatic webbing loom, the automatic webbing looms of various models can be selected in the prior art, and woven belt products of various specifications can be produced. The above-mentioned equipment has realized continuous, automated production process, except that the initial operation of getting on the production line needs the manual assistance, inkle loom can uninterruptedly produce the meshbelt product in succession.

The woven belt needs to be cut into a certain specification (as long as the woven belt is a certain length, such as 100m and 150 m) before leaving a factory, and the woven belt is generally wound into a roll shape after being cut, so that subsequent packaging and delivery are facilitated, and the woven belt is convenient to take. With the increasing expansion of production scale, the traditional manual cutting mode is difficult to meet the increasing production requirements, the manual cutting generally adopts a heating wire heating cutting or guillotine cutting method, the two tape cutting process equipment investment is low, but the labor cost is high, in addition, when the heating wire is used for cutting, great smoke is generated, and the generated smoke can influence the production environment and the health of workers; and a burn mark may be left on the cut surface of the braid. Although the cutting of the guillotine has no smoke and burnt traces, the phenomenon of scattered opening (namely beard edge) can occur when the guillotine cannot effectively seal the opening. In actual processing, the phenomenon of opening scattering caused by manual cutting is mainly caused by the fact that the woven belt is fiddled in the manual cutting process (including the woven belt is pulled onto a guillotine and the end of the woven belt is taken off from the guillotine after cutting), namely, the problem of opening scattering is likely to occur due to the intervention of more personnel.

Therefore, the development of automatic blanking equipment has very important significance for the continuous production of the mesh belt, not only can be matched with a ribbon loom to carry out blanking and guiding on mesh belt products, but also is favorable for carrying out cutting forming and manual sealing on the mesh belt products in an automatic mode, and has important effect on improving the product quality.
