Description

A pattern machine for automatic sewing

technical field

The invention belongs to the field of machinery, and in particular relates to a pattern machine.

technical background

Computer pattern machine is the most advanced machine used in handbag factories, shoe factories, luggage factories, garment factories, leather goods factories and furniture factories. It can realize traditional manual patterns with high speed and high efficiency, and can also realize The requirements of "multi-level, multi-functional, uniform and perfect" cannot be achieved by hand-made patterns. It is an electromechanical product that embodies a variety of high-tech. Since each model has a variety of specifications such as machine head, number of machine needles, frame form, and stitch form, if these are combined and arranged at the same time, and classified in detail, the embroidery machine type will be a large number. It can meet the sewing needs of different levels. For the existing pattern machines used in garment making, most of them adopt the method of fixing the sewing platform, that is, place the base fabric disassembled on one side on the top of the platform, and then paste the sample fabric that needs to be sewn on the fixed position for sewing. For the sewing of the two, the sample cloth needs to be positioned and pressed manually, and timely manual adjustment is performed during the sewing process, which causes low production efficiency and endangers personal safety during the sewing process. Patent No. 200910097311.3 discloses a cloth pressing frame, which can fix the sample cloth to achieve the purpose of auxiliary sewing, but the fixing structure is too cumbersome, and it can be understood from its structure that multiple processes are required to fix the sample cloth Although the fixed structure is stable, the production efficiency has not been improved.

Contents of the invention

The technical problem to be solved by the present invention is to provide a pattern machine which can conveniently fix the sample cloth for sewing, and can adjust correspondingly according to the relative position of the sample cloth and the base cloth.

An automatic sewing pattern machine according to the present invention comprises a sewing needle unit, a sewing platform, a bottom frame for pressing cloth and an upper frame for pressing cloth, both of which are hollow and square, and the The bottom frame of the cloth press and the upper frame of the cloth press are fixed directly above the front end of the sewing platform, and the edges of the bottom frame of the press cloth and the upper frame of the cloth press are attached to each other, and the sewing needle unit is located above the sewing platform. The upper surfaces of the two opposite sides of the cloth-pressing bottom frame are provided with a sample cloth fixing strip, and one end of the sample cloth fixing strip is fixed at a position close to the rear edge of the cloth-pressing bottom frame, forming a semi-closed structure with the cloth-pressing bottom frame; The cloth pressing bottom frame and the cloth pressing upper frame are fixed on the cloth pressing driving module, and the cloth sewing platform is fixed on the platform driving module.

As a further description of the above-mentioned automatic sewing pattern machine, the platform drive module is provided with a guide slide rail, and the cloth press drive module is placed on the guide slide rail, and moves back and forth along the horizontal direction of the guide slide rail .

As a further description of the above-mentioned automatic sewing pattern machine, the cloth pressing drive module includes a fixed seat, a horizontal interlocking cylinder and a horizontal push block, the bottom frame of the cloth pressing and the upper frame of the cloth pressing are fixed on the fixing seat, The horizontal push block is strip-shaped, and the horizontal push block abuts against the fixed seat and is perpendicular to the moving direction of the horizontal interlocking cylinder.

As a further description of the above-mentioned automatic sewing pattern machine, both sides of the fixed seat that fixes the upper frame of the cloth press are provided with a cloth press adjustment cylinder and an adjustment rotary block, and one end of the adjustment rotary block is connected to the cloth press adjustment The cylinder is connected, and the other end is connected with the cloth pressing upper frame, the bottom of the adjusting rotary block is fixed with the fixed seat, and the cloth pressing adjusting cylinder controls the upper cloth pressing frame to move up and down by adjusting the rotation of the rotating block.

As a further description of the above automatic sewing pattern machine, the length of the horizontal push block is greater than the width of the fixed seat.

The beneficial effects of the present invention are: by separating the combination of the sewing platform, the bottom frame of the cloth pressing, and the upper frame of the cloth pressing from each other, and then using a plurality of drive cylinders, the modules of the cloth pressing part can be respectively controlled to translate relative to the sewing cloth platform. During the sewing process, it can meet the needs of adjusting the position of the sample cloth and the base cloth when sewing patterns on clothes. At the same time, the fixing strips set on the surface of the bottom frame of the press cloth can facilitate the pressing of the sample cloth, and cooperate with the combination of the upper frame of the press cloth to play a fixed role function, and the semi-closed fixing strip structure is easier to separate the sample cloth or fine-tune the position when the upper frame of the press cloth is not combined. Its overall fast assembly and disassembly, automatic operation and stable performance are relatively general. The structure has been significantly improved. Furthermore, using guide rails and horizontal push blocks for horizontal translation, the force point is a line segment instead of a single point, which is more stable during the movement process. As for the set adjustment rotary block, the driving horizontal linear motion is converted into the up and down motion of the upper frame of the cloth pressing, which saves the space occupied in the vertical direction.
