Technical field
[000 1] The utility model relates to the field of sewing equipment accessories, in particular to a double-fold drawing cylinder.
technical background
[0002] In the sewing process, it is often necessary to curl the cloth before sewing. Manual hemming is inefficient, time-consuming and incomplete, which affects product quality. In order to improve work efficiency and product quality, auxiliary tools are often used. Cylinder pulling, also known as edge rolling machine, edge rolling cylinder, knitting cylinder and edge sewing machine, is a common auxiliary tool for various sewing equipment such as clothing, leather and luggage. The existing wire drawing cylinder is usually fixed on the sewing machine directly by bolts, which can not be fine-tuned, and will bring some trouble to workers.

Brief description of drawings
[00 13] The preferred embodiment of the utility model will be described in detail or preferably with the attached drawings, in which,
[00 14] Figure 1 is a schematic diagram of the folding drawer of the utility model;
[00 15] fig. 2 is a schematic diagram of the folding cylinder cover plate of the utility model when it is opened.
expand on
[00 16] with reference to fig. 1 to fig. 2, the embodiment of the double-fold drawer of the utility model is further explained.
[00 17]- A double-folding drawer comprises a molding body 1, which gradually protrudes in a U-shape from back to front, and the tail of the molding body 1 is connected with a buffer block 1 1, and the molding body/kloc When the cloth is stuck in work, the situation of the stuck cloth can be seen through the rectangular groove 32, and the cloth can be taken out. The head of the molding cover 3 and the head of the molded body 1 form a discharge port 4, which is U-shaped, and the tail of the molding cover 3 and the tail of the molded body 1 form a feed port 5, which is flat.
[00 18] The shaping outer cover 3 is fixed on the shaping body 1 by welding or riveting. The shaping body 1 is hollow inside, which can make the drawing tube lighter, save materials and reduce production cost. The fixing device 3 1 is L-shaped, and the fixing device 3 1 is L-shaped.
[00 19] As a better design, the special-shaped cover 3 is designed to be openable, including a cover body 33, a cover plate 34 is arranged above the cover body, the cover plate 34 is hinged with the cover body 33, a buckle 34 1 is arranged in front of the cover plate 34, and a buckle protrusion 33 1 is arranged on the cover body 33. The buckle 34 1 matches the buckle protrusion 33 1. In this design, when feeding, it is only necessary to open the cover plate 34 to feed directly, without feeding from the feed port 5, which is time-consuming and laborious. When the material is stuck during processing, it is only necessary to open the cover plate 34 to adjust or re-feed.
[0020] Finally, it should be noted that the above is only the preferred embodiment of the utility model and is not used to limit the utility model. Although the utility model has been described in detail with reference to the above-mentioned embodiments, the technical scheme recorded in the above-mentioned embodiments can still be modified or some technical features can be replaced by equivalents. Any modification, equivalent substitution or equivalent substitution within the spirit and principle of the utility model.
