Split electronic pattern sewing machine

Abstract

The invention discloses a split electronic pattern sewing machine, which comprises a machine seat, a machined body fixed on the machine seat, a machine head, an upper feeding bow and a lower feeding carriage, wherein a lifting device is arranged between the machine body and the machine head; the machine head is arranged on the lifting device and can move up and down; a closed type clutch for realizing the transmission connection between the machine body and the machine head is arranged between the machine body and the machine head; the lifting device is also connected with a compressing device which can synchronously lift with the machine head as well as compress sewn materials; after compressing the sewn materials, the compressing device synchronously moves with the upper feeding bow and the lower feeding carriage for feeding; and a frame needle arranged on the machine head sews patterns on the sewn materials. In the split electronic pattern sewing machine, the separation of the machine head and the machine body of the prior integrated electronic pattern sewing machine is realized and the lifting device is used to raise the machine head to ensure enough layer space of the machine head, so the requirements for sewing patterns on less than 90 millimeter extra-thick materials are met, the influences of human factors on product quality during manual operation are overcome, cost is saved, efficiency is improved, and labor intensity is reduced.

Description

Technical field [0001] The invention relates to the technical field of sewing machines, in particular to a split electronic pattern machine. Background technique [0002] With the continuous improvement of people’s demand for clothing and home culture, there is a type of special thick material sewing products such as seat cushions, backrests, home textile products, etc., which exceed the maximum lifting height of 35mm of ordinary sewing machine presser feet. Therefore, this type of sewing products Normally, it is impossible to sew directly with ordinary sewing machines. Once you need it, you can only use manual methods. Make a frame in advance. After the sewing material is pressed tightly, use manual method to sew. Even a good sewing worker can hardly make a satisfactory pattern effect. At present, there is a large gap in the skilled sewing worker of garment enterprises, and the labor cost is gradually increasing. Therefore, to solve the problem of sewing materials with 35mm or m...

Problems solved by technology

[0002] With the continuous improvement of people's demand for clothing and home culture, there is a special class of sewing products made of thick materials, such as seat cushions, backrests, and home textile products, which exceed the limit of the maximum lifting height of the ordinary sewing machine presser foot of 35mm. Therefore, this type of sewing products It is usually impossible to sew directly with an ordinary sewing machine. Once it is necessary, it can only be done manually. A frame is made in advance, and after the sewing material is pressed tightly, it is sewed by hand. Even a good seamstress can hardly make a satisfactory pattern effect. However, there is a large gap in the skilled seamstresses of garment enterprises, and the labor cost is gradually increasing.

Therefore, to solve the problem of using machines to sew materials above 35mm, people have thought of using a method of increasing the space distance between the sewing machine head and the bottom plate, so that there is enough space between the machine head and the bottom plate to carry out sewing. There are two main problems in this method for sewing materials above 35mm: one is that the stroke of the machine head is not enough after the distance between the machine head and the bottom plate is increased, and the needle needs to be thickened and lengthened. The result is that the sewing product is destroyed after the machine needle is thickened. Second, after the machine needle is lengthened, it is easy to produce a "bow" in the sewing process, so that the sewing effect cannot be achieved. The stability of quality also has a greater impact
