Description

Technical Field

[0001] The utility model relates to the technical field of fish slaughtering equipment, and particularly relates to a sewing device for PU slipper production. Background Art

[0002] PU slippers refer to slippers made mainly of polyurethane (abbreviated as PU) materials. PU materials have a low density, are soft in texture, light and comfortable to wear, have good elasticity and toughness, can adapt to the shape of the feet, provide good support, and have better abrasion resistance and oxidation resistance compared to some other plastic materials, extending the service life of the slippers. Compared with some traditional plastics, PU materials are easier to recycle and process to a certain extent, with less impact on the environment. Although they are synthetic materials, PU slippers are often designed with breathability in mind to reduce the stuffiness of the feet.

[0003] However, in traditional production processes, manual or semi-automatic methods are mainly used. When sewing slippers, it is mostly manual to hold the slippers and place them at the sewing machine to sew and hem the edges. However, due to the soft materials of the insole and upper of PU slippers, it is quite strenuous to hold and sew them, especially for novice operators, which is time-consuming and laborious, greatly reducing the production efficiency. Moreover, a general sewing machine requires scissors to cut the sewing thread after sewing, increasing the operation time and reducing the production efficiency. Summary of the Utility Model

[0004] In view of this, the utility model provides a sewing device for PU slipper production, which realizes the smooth movement, precise positioning, rapid pressing down and automatic cutting of the slippers during the sewing process through the mutual cooperation of a sliding component, a clamping component, and a cutting component. By symmetrically arranging the rolling shafts and balls, the smooth sliding of the slipper bottom during the sewing process is ensured, reducing the frictional resistance and wear, and improving the production efficiency and the durability of the product.

[0005] To solve the above technical problems, the utility model provides a sewing device for PU slipper production, which includes a bottom plate. A sewing mechanism is arranged on the bottom plate, and the sewing mechanism includes a sliding component for the movement of the slippers and a clamping component for pressing down the slippers.
