[0003] A traditional interlock sewing machine consists of a machine head, an interlock sewing machine table and an interlock sewing machine frame. When the interlock sewing machine is started, the fabric to be processed is placed on the interlock sewing machine table. The user feeds the fabric to be processed under the machine head, the machine head starts working, the sewing needle passes through the fabric and completes the sewing. When the interlock sewing machine is processing elastic fabric, the user is required to manually stretch the two sides of the fabric and move the fabric with the working rhythm of the sewing needle to keep the fabric flat during processing to achieve good sewing stitches. However, due to the poor stability of manual pulling of the fabric and the difficulty of one person completing the steps of stretching, flattening and sewing of the fabric at the same time, it is easy to cause position deviation of the elastic fabric during sewing, resulting in duplication or distortion of the sewn chain sewing thread, which reduces the processing efficiency of the interlock sewing machine and increases the rework rate.

[0026] Example:

[0027] As attached Figure 1 To Attachment Figure 6 As shown:

[0028] The utility model provides a material supporting device of a stretch sewing machine, comprising a stretch sewing machine table 1 on a machine body, a machine head 2 is installed on the stretch sewing machine table 1, cloth to be processed and sewn is placed under the machine head 2, one end of the machine head 2 is connected with a sewing needle 3, and the sewing needle 3 drives cotton thread to pass through the cloth to complete sewing.

[0029] like Figure 1 to Figure 2 As shown, grooves 4 are provided on both sides of the sewing needle 3 on the interlock sewing machine table 1, a frame 5 is arranged in the groove 4, a synchronous belt transmission mechanism 6 is passed through the frame 5, and a motor is arranged on one side of the frame 5. The synchronous belt transmission mechanism 6 is a belt drive, and the motion is transmitted by the meshing of the equidistantly distributed transverse teeth on the inner surface of the synchronous belt in the synchronous belt transmission mechanism 6 and the corresponding teeth and grooves on the driving wheel and the driven wheel. The driving source of the driving wheel is the motor, and the driving shaft of the motor passes through the side wall of the frame 5 and is connected to the synchronous belt transmission mechanism 6, thereby realizing the transmission of power; the synchronous belt transmission mechanism 6 is a prior art and is not described in detail in the present utility model.

[0030] like Figures 2 to 3 As shown, two fixing sleeves 71 are fixedly provided on one side of the top of the frame 5, and a moving rod 72 is slidably penetrated in each of the two fixing sleeves 71. A plurality of locking holes 8 are provided on the moving rod 72, and the plurality of locking holes 8 are vertically distributed. The fixing sleeve 71 and the moving rod 72 are connected by bolts 9, and one end of the bolt 9 passes through the locking hole 8 corresponding to a suitable height to connect the fixing sleeve 71 and the moving rod 72, so as to achieve fixed locking between the fixing sleeve 71 and the moving rod 72. The setting of the locking hole 8 can facilitate the user to accurately control the position of the moving rod 72 and provide stable support.

[0031] like Figure 2 As shown, the two moving rods 72 are connected as a whole through the fixed plate 10, and a plurality of connecting rods 111 are arranged at the bottom of the fixed plate 10, and the plurality of connecting rods 111 are linearly distributed, and a support rod 112 is slidably penetrated inside the plurality of connecting rods 111, and the connecting rod 111 and the support rod 112 are connected by a compression spring 15, and a U-shaped fixing block 12 is fixedly arranged at the bottom of the support rod 112, and a roller 13 is rotatably connected inside the U-shaped fixing block 12, and the setting of the compression spring 15 can make the support rod 112 have a certain elastic supporting force, so as to ensure that the roller 13 always keeps in contact with the synchronous belt, and the contact between the roller 13 and the synchronous belt can apply a certain pressure to the processed elastic fabric on the synchronous belt transmission mechanism 6, so as to achieve the pressing effect on the elastic fabric, so that the fabric on the interlock sewing machine table 1 is stretched and flat, and the deviation of the fabric position during the sewing process is avoided, and the processing efficiency of the interlock sewing machine is improved;

[0032] The compression spring 15 can store and release energy. When the fixed plate 10 moves upward with the moving rod 72, the compression spring 15 in the connecting rod 111 relaxes and rebounds, which can help the roller 13 at the bottom of the support rod 112 to abut against the synchronous belt. When the fixed plate 10 moves downward with the moving rod 72, the fixed plate 10 applies a certain pressure to the connecting rod 111, and the compression spring 15 in the connecting rod 111 is further compressed to help the roller 13 at the bottom of the support rod 112 to abut against the synchronous belt. The user places both sides of the processed elastic fabric flat on the synchronous belt, and selects the locking hole 8 of a suitable height according to the contact state between the roller 13 and the fabric on the synchronous belt, so that the compression spring 15 is compressed or rebounded accordingly at this height, one end of the bolt 9 is aligned with the locking hole 8 of a suitable height for locking and fixing, and then the bolt 9 is manually turned to connect and fix the moving rod 72 with the fixing sleeve 71, thereby effectively realizing the pressure adjustment of the compression spring 15 by selecting the locking hole 8 of a suitable height.

[0033] like Figure 2 As shown, a moving assembly 14 is provided in each of the two grooves 4, and the moving assembly 14 includes two linear guide rails 141 provided in the groove 4, and the two linear guide rails 141 are relatively parallelly arranged, and two sliders 142 are slidably provided on the linear guide rails 141, and the two sliders 142 are respectively located on both sides of the bottom of the frame 5, and the two sliders 142 are connected to the side wall of the frame 5 through a fixed seat 143, and a screw rod 144 is provided in the groove 4, and one end of the screw rod 144 passes through the side wall of the interlock sewing machine table 1 and is connected to the hand wheel, and a connecting block 145 is sleeved on the screw rod 144, and the screw rod 144 is threadedly connected to the connecting block 145, and one side of the connecting block 145 is connected to the frame 5, when the user turns the hand wheel, the hand wheel drives the screw rod 144 to rotate, and the screw rod 144 is threadedly connected to the connecting block 145, which effectively transmits the rotational power to the synchronous belt transmission mechanism 6, and the synchronous belt transmission mechanism 6 moves smoothly to the left or right on the linear guide rail 141 along with the slider 142. The setting of the linear guide rail 141 restricts the synchronous belt transmission mechanism 6 from rotating and can only slide along a predetermined direction, thereby converting the rotational motion into a linear motion. The synchronous belt transmission mechanism 6 moves to the left or right on the screw rod 144, which is convenient for the user to adjust the position according to the width difference of the fabric, thereby improving the processing efficiency of the interlock sewing machine.

[0034] When using:

[0035] Place the fabric to be processed on the interlock sewing machine table 1, manually adjust the hand wheel according to the width difference of the fabric, and drive the screw rod 144 through the hand wheel to drive the synchronous belt transmission mechanism 6 to move left or right along the slider 142 on the linear guide rail 141, and place one side of the fabric on the surface of the synchronous belt in the synchronous belt transmission mechanism 6, and adjust the locking hole 8 on the moving rod 72 to a suitable height according to the thickness difference of different fabrics, and manually turn the bolt 9 to fix the moving rod 72 and the fixed sleeve 71, and the connecting rod 111 applies pressure to the roller 13 at the bottom of the support rod 112 through the elastic force of the compression spring 15 to ensure that the roller 13 is always in sync with the The fabric on the belt contacts and exerts a certain pressure, the motor is turned on, and the motor drives the synchronous belt transmission mechanism 6 to rotate. There is friction between the synchronous belt and the fabric, and the rotation of the synchronous belt will drive the fabric to move forward together. The roller 13 applies pressure downward to squeeze the fabric. The pressure enhances the friction between the synchronous belt and the fabric, making it easier for the fabric to be driven by the synchronous belt. The roller 13 also rotates with it and keeps in contact with the fabric, ensuring that the fabric can move forward stably under the drive of the synchronous belt, thereby achieving the tensioning and flattening of the elastic fabric, avoiding the position deviation of the elastic fabric during the sewing process, and improving the processing efficiency of the interlock sewing machine.
