Description

Technical Field

[0001] The utility model relates to the technical field of elastic band limiting of a stretch sewing machine, and specifically discloses an elastic band limiting device for a stretch sewing machine. Background Art

[0002] A bed cover sewing machine is a machine used to sew knitted garments worn next to the body. It uses two types of sewing threads, needle and shuttle, to form a single-sided covered chain stitch on the bottom of the sewing material, or add a covering thread on the front of the sewing material to form a double-sided covered chain stitch, and sew two or more layers of sewing material. A bed sheet refers to a cloth cover that is directly put on the mattress. Its main purpose is to wrap the mattress, and it can also be used as a bed sheet. The main purpose of a bed sheet is to wrap the mattress. The mattress itself is very easy to get dusty and dirty. Coupled with human damage, it will become very dirty in a short time, and it is also very inconvenient to clean. The bed sheet solves this problem. The bed sheet can protect the mattress. The bed sheet can also be used as a bed sheet. And when used as a bed sheet, it is easier to fix and non-slip than ordinary sheets.

[0003] The fitted sheet needs to be sewn with elastic using a flat sewing machine. Currently, when sewing the elastic, manual operation is required to put the elastic into the rolled edge fabric and sew it.

[0004] The above process has the following drawbacks: the upper and lower layers of fabric of the elastic band are not placed evenly, the elastic band falls off, and the width is uneven, resulting in the elastic band in the curling edge not being fully placed, the elastic force of the elastic band cannot be pulled out, and the rebound effect of the finished product does not meet the requirements. In severe cases, it will lead to a high rework rate and affect production efficiency. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides an elastic limiting device for a stretch sewing machine to solve the problems of incomplete placement of the elastic in the curling edge, failure to pull out the elastic force of the elastic, and unsatisfactory rebound effect of the finished product due to uneven placement of the upper and lower layers of fabric of the elastic, falling off the bed, and uneven width, which in severe cases will lead to a high rework rate and affect production efficiency.

[0006] To achieve the above purpose, the technical solution of the utility model is:

[0007] A rubber band limiting device for a stretch sewing machine comprises a bottom plate, a baffle plate is slidably mounted at each end of the bottom plate, the sliding directions of the two baffle plates are parallel and opposite to each other; a scale is arranged on the bottom plate to match the baffle plate; and a fixing hole is also arranged on the bottom plate. When in use, the bottom plate is fixed to the stretch sewing machine by screws, the width of the upper and lower layers of fabric is adjusted by the scale plate, the rubber band and the hem are placed between the two baffle plates, the upper and lower layers of fabric of the rubber band are limited to be placed, and the rubber band is prevented from falling off the bed, and the width is ensured to be uniform, the fullness and elasticity of the rubber band are ensured, the production continuity is ensured, and the production efficiency is ensured.

[0008] Preferably, a slide groove 1 is provided on the upper part of the bottom plate; a slide groove 2 is provided on the lower part of the bottom plate; baffles are provided in the slide grooves 1 and 2. The provision of the slide grooves 1 and 2 ensures the stability of the baffles and the stability of the placement of the elastic band between the upper and lower layers of fabric.

[0009] Preferably, a U-shaped plate is provided at one end of the baffle plate close to another baffle plate, the opening direction of the U-shaped plate is parallel to the sliding direction of the baffle plate, and the openings of the two U-shaped plates are arranged opposite to each other; a through hole is also provided on the baffle plate. The opening ends of the U-shaped plates of the two baffle plates are arranged opposite to each other, which is convenient for restricting the elastic band and the fabric.

[0010] Preferably, the bottom surfaces of the first and second slide grooves are both provided with long holes. The slide plate is fixed to the interlock sewing machine by screws passing through the through holes and the long holes. The provision of the long holes facilitates the adjustment of the position of the slide plate in the first and second slide grooves to ensure the distance between the two baffles.

[0011] Preferably, rounded corners are provided at the ends of the baffle to avoid scratching the fabric.

[0012] Preferably, the fixing hole is arranged in a long hole shape as a whole, so as to facilitate the adjustment of the baffle.
