Description

Technical Field

[0001] The utility model relates to the technical field of chenille mat hemming equipment, in particular to a sewing hemming device for producing chenille mats. Background Art

[0002] Chenille, also known as velvet, is a new type of fancy yarn. It is made of two strands as the core thread, and the feather yarn is sandwiched in the middle by twisting. The main products are sofa covers, bedspreads, bed blankets, table blankets, etc. The processing flow of chenille floor mats is mainly to spin polyester filaments or nylon filaments to obtain chenille long yarns, use polyester fabric as the bottom, tuft the chenille long yarns on the bottom one by one, and obtain white embryo fabrics. Dye according to needs, check whether there are missed stitches and dyeing colors, choose the appropriate anti-slip glue for floor mats, spread the glue horizontally on the back of the white embryo fabric, cut the required specifications, and sew the edges.

[0003] However, the manual hemming currently used results in a slow hemming speed, which reduces work efficiency. In addition, manual hemming is prone to errors and cannot guarantee accuracy, resulting in a decrease in carpet quality and failing to meet the work requirements for carpet hemming.

[0004] For example, a carpet processing hemming device disclosed in Chinese patent publication number CN219174770U places the carpet on the top of the carpet placing table and uses the device to pull from left to right. We can set the operation through the control button and control switch at the front end of the workbench, and then the device can automatically sew and hem the carpet while it moves to the right.

[0005] The existing technology has the following problems:

[0006] However, the carpet or floor mat in the above-mentioned device lacks a corresponding guiding mechanism during the hemming process. Therefore, it is easy for the floor mat and the hemming fabric to not fit together during the hemming process. In this case, when the hemming is sewn, wrinkles and fabric folding may easily occur at the hemming seams, resulting in a product that does not meet standard requirements and is unsightly.
