Background technique

With the rapid development of the economy, people's living standards continue to improve, labor laws continue to improve, labor wages, factory rents and other expenses in various places generally rise, and overtime hours are also strictly controlled. As a result, the production cost of the garment industry is also relatively increasing, and due to the control of overtime hours, the output is relatively reduced. Now each production factory generally is that everyone operates a common single-head herringbone sewing machine to do a single process operation. For example: After the elastic band is attached to the fabric with a single-head herringbone sewing machine, the surface of the fabric is turned again with a single-head herringbone sewing machine. This process is incorporated into the assembly line operation, and two herringbone sewing machines and two workers must be used to complete the operation. Due to the continuous increase of manufacturers, the competition has become more and more fierce, causing major factories to lower product prices to obtain more orders, which has caused vicious competition. Due to the increase of production costs and the reduction of product prices, the profits of enterprises are getting less and less. Most small factories cannot bear this fierce competition and have closed down one after another. Therefore, the industry is doing everything possible to improve production efficiency and reduce costs in order to survive and develop.

Detailed ways

Fig. 1 has shown the basic structure of preferred embodiment of the present invention, described double-head herringbone sewing machine, comprises frame 2, is located at the panel 1 of this frame top, is located at the pedal 5 of frame bottom And connecting rod 01 thereof, be located at the motor 3 of the below of this panel, be located at the driving pulley 4 on the motor output shaft, the foot switch of the starter motor that is connected with the connecting rod 01 of pedal. The panel is provided with two herringbone sewing heads in parallel, wherein the first herringbone sewing head 03 is provided with a driven pulley 8 and a first synchronous pulley 9 in turn on the rotating shaft, and the second herringbone sewing head 04 The rotating shaft is provided with the second synchronous pulley 10 that cooperates with the first synchronous pulley 9, and the first and second synchronous pulleys are connected by a synchronous belt 11, and the driven belt of the first herringbone sewing machine head The driving pulley 4 on the wheel 8 and the motor is connected by a belt 7, and the panel between the first and second herringbone sewing heads is provided with a turning mechanism and a blower. As shown in FIG. 2 , in this embodiment, the turning mechanism includes: a turning plate 12 with a twisted surface and a support plate 13 for fixing the turning plate on the panel. The blowing device comprises: two blowing pipes 14 facing the folding plate 12 in the folding mechanism, and the blowing pipes are connected with an external air compressor through a pressure regulating valve 15 arranged on the frame. The switch of the press and the foot switch of the starter motor are combined into an integrated switch 02.

In order to save costs, in this embodiment, the single-head herringbone sewing machine is refitted into a double-head herringbone sewing machine, and the modification steps are as follows:

Step 1: Cut out the through hole 16 (as shown in FIG. 4 ) according to the size of installing two herringbone sewing heads on the panel 1 supporting one herringbone sewing head (as shown in FIG. 3 ).

Please refer to Figure 1 for the following steps

Step 2: Install the first and second herringbone sewing machine heads 03, 04 in parallel on the panel 1, and make the presser feet 17, 18 of the two sewing machines be on the straight line of the sewing channel.

Step 3: Connect the driven pulley 8 on the head of the first herringbone sewing machine with the driving pulley 4 located on the output shaft of the motor with the belt 7 .

Step 4: Install the first synchronous pulley 9 on the outer side of the driven wheel 8 of the first herringbone sewing machine head, install the second synchronous pulley 10 on the rotating shaft on the side of the second herringbone sewing machine head, and use the synchronous belt 11 Connect the first and second synchronous pulleys.

Step 5: On the panel between the two herringbone sewing machine heads, install a folding mechanism and a blowing device. The blowing device is externally connected to an air compressor through a pressure regulating valve 15, and controls the switch of the motor and the control of the air pressure. The switch of the sewing machine is combined and installed into an integrated switch 02, which is connected with the connecting rod 01 of the sewing machine pedal, so as to control the on/off of the motor and the air compressor at the same time. Please refer to FIG. 2 , in this embodiment, the folding mechanism includes: a folding plate 12 with a twisted surface and a support plate 13 for fixing the folding plate on the panel 1 . The blowing device includes: two blowing pipes 14 facing the folding plate 12 in the folding mechanism, and the blowing pipes are connected with an external air compressor through a pressure regulating valve 15 arranged on the frame 2 . The pressure regulating valve 15 can be a single spool, which provides the same pressure gas to the two blowing pipes; it can also be a double spool, which provides the two blowing pipes with different pressures of gas, for different quality Material processing.

As shown in Figure 1, when the sewing machine of the present invention needs to work, the pedal 5 of the sewing machine is stepped on, and the integrated switch 02 is opened through the connecting rod 01 of the pedal, so that the driving wheel 4 on the motor shaft drives the slave of the first herringbone sewing machine head. The driving wheel 8 rotates, and the second synchronous pulley 10 is driven by the first synchronous pulley 9, so that the rotating shaft of the second herringbone sewing head 04 is driven to work. At the same time, the external air compressor also starts to feed air, and the pressure regulating valve 15 can be adjusted as required to provide the two blowing pipes 14 with gas of appropriate pressure. If the work needs to be stopped, as long as the pedal 5 of the sewing machine is stepped on, the integrated switch 02 can interrupt the work of the sewing machine and the air compressor at the same time. That is, only when the sewing machine is rotating and operating, the blowing pipe will blow air.

As shown in Figure 5, the elastic band 20 is superimposed on the cloth 30, and placed in the presser foot 17 of the first herringbone sewing machine head, the presser foot presses the cloth and the elastic band to feed forward, while the sewing machine goes out the herringbone line and Do the first seam of the fabric and elastic. After the first herringbone sewing machine head 03 puts the elastic band on the cloth, it continuously feeds the material forward. When the elastic band 20 passes through the twisted surface of the folding plate 12, the elastic band turns 180 degrees to the right, and simultaneously drives the cloth 30 and the elastic band. The stitching edge also turns right 180 degrees, that is, the stitching edge is folded to the bottom of the fabric on the left side of the stitching edge, so that when entering the presser foot 18 of the second herringbone sewing machine head 04, the cloth is already facing upwards, and the stitching edge Fold it under the fabric. At this time, the needle of the second herringbone sewing machine head just hits the second herringbone line on the surface of the fabric, that is, the fabric and the elastic are stitched for the second time. Wherein when the material to be processed passes through the folding plate 12, two blowing pipes 14 blow to produce effect, and the cloth that is folded is blown flat, feels like the cloth feeding function of people when operating.

The present invention expands a herringbone sewing machine into a double-headed herringbone sewing machine, which can be used by two people to use two equipment to operate two processes respectively - making herringbone on the front and back of the cloth. , and only one person needs to operate one piece of equipment to complete it in one process. Utilizing the device of the present invention not only effectively solves the problem of high labor cost at present, but also can greatly improve production efficiency, thereby enhancing the competitiveness of enterprises.
