[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] The present application embodiment discloses a pattern sewing machine rolling plate. Figure 1 and Figure 2 , a pattern sewing machine rolling plate, comprising a columnar support column 1, and a block-shaped fixing seat 2 is fixedly connected to the outer surface of the support column 1, and a set screw 3 is screwed and connected to the lower surface of the fixing seat 2. The fixing seat 2 is clamped on the edge of the table of the sewing machine, and then the set screw 3 is rotated so that the upper surface of the set screw 3 is against the lower surface of the table, so that the device can be stably fixed on the sewing machine, and a disc-shaped support plate 4 is fixedly connected to the outer surface of the support column 1 above the fixing seat 2, and an annular limiting ring 5 is fixedly connected to the upper surface of the support plate 4, and a square groove 6 is penetrated and opened on the outer surface of the limiting ring 5, and two block-shaped rubber blocks 13 are fixedly connected to the inner wall of the square groove 6, and the rolling strip is passed through the rubber block 13 for sewing, and the friction of the two rubber blocks 13 can prevent the rolling strip from slipping, thereby improving the sewing quality of the rolling strip;

[0023] Secondly, a tubular sleeve 7 is rotatably connected to the outer surface of the support column 1 above the support plate 4, and a plurality of rectangular fixed blocks 8 are fixedly connected to the outer surface of the sleeve 7, and the side surfaces of the plurality of fixed blocks 8 are slidably connected to rectangular adjusting blocks 9. The plurality of adjusting blocks 9 slide on the side surfaces of the fixed blocks 8, so that the side surfaces of the plurality of adjusting blocks 9 are closely attached to the inner wall of the rolling strip cloth cylinder, so as to stably fix the rolling strip cloth cylinders of different diameters, thereby preventing the rolling strip cylinder from deviating from the support column 1 when rotating during the process of sewing the rolling strip, thereby avoiding the rolling strip from loosening. The loose threads on the roll strip 4 cause the sewing quality to decrease. At the same time, a rectangular fixing rod 10 is fixedly connected to the upper surface of the support plate 4, and a block-shaped connecting slider 11 is slidably connected to the side surface of the fixing rod 10. The side surface of the connecting slider 11 is rotatably connected to a cube-shaped limiting rod 12. After the rolling strip is installed, the limiting rod 12 is rotated and then driven to slide down by sliding the connecting slider 11, so that the limiting rod 12 is closely attached to the side surface of the rolling strip, and then the rolling strip is pressed, so as to avoid the phenomenon of the rolling strip deviating up and down during the rotation process, thereby improving the sewing effect.

[0024] Reference Figure 2 A T-groove-shaped slide groove 17 is opened on the side surface of the fixed rod 10, and a stud 18 is rotatably connected to the inner wall of the slide groove 17. The outer surface of the stud 18 is screwed and connected to the connecting slider 11 through a ball screw. The connecting slider 11 slides relatively with the inner wall of the slide groove 17, and the upper end of the stud 18 penetrates the fixed rod 10 to its outer side, and is fixedly connected with a disc-shaped rotating disk 19, so that the stud 18 can be driven to rotate by rotating the rotating disk 19, so that the connecting slider 11 can slide up and down on the inner wall of the slide groove 17 under the action of the ball screw, thereby driving the limit rod 12 to slide up and down, so as to be close to the upper surface of the rolling strip, thereby performing side limit on rolling strips of different widths.

[0025] Reference Figure 2 and Figure 3 , engaging holes 14 are provided on the side surfaces of several fixed blocks 8, columnar limiting grooves 15 are provided on the side surfaces of several adjusting blocks 9, and block-shaped limiting blocks 16 are elastically slidably connected to the inner walls of several limiting grooves 15 through springs, and several limiting blocks 16 can be engaged with the inner walls of several engaging holes 14. When it is necessary to adapt to rolling strip cloth barrels with different pipe diameters, the limiting block 16 is pressed, and then the adjusting block 9 is slid a certain distance, and then the limiting block 16 will rebound and engage with the inner wall of the corresponding engaging hole 14 under the resetting action of the spring, so that the fixed block 8 is stably fixed, so that it can be suitable for rolling strip cloth barrels with different pipe diameters, thereby improving the practicality of the device.

[0026] The implementation principle of the rolling plate of a pattern sewing machine in the embodiment of the present application is as follows: by engaging the fixing seat 2 on the edge of the sewing machine table, and then rotating the fixing screw 3 so that the upper surface of the fixing screw 3 is against the lower surface of the table, so as to stably fix the device on the sewing machine, and then by sliding a plurality of adjusting blocks 9 on the side surface of the fixing block 8, a plurality of limiting blocks 16 are engaged with the inner walls of the corresponding plurality of engaging holes 14, so that the side surfaces of the plurality of adjusting blocks 9 are closely attached to the inner wall of the rolling strip cloth barrel, so as to stably fix the rolling strip cloth barrels of different diameters, prevent the rolling strip barrel from deviating from the support column 1 when rotating, and avoid the rolling strip from loosening. The limit rod 12 is then rotated to be located directly above the rolling strip, and the stud 18 is then driven to rotate by rotating the rotating disk 19, thereby driving the connecting slider 11 to slide up and down on the inner wall of the slide groove 17 under the action of the ball screw, thereby driving the limit rod 12 to slide downward, so that the limit rod 12 is close to the side surface of the rolling strip, and then the rolling strip is pressed tightly to avoid the rolling strip from deviating up and down during the rotation process, thereby improving the sewing effect, and finally the rolling strip is passed through the rubber block 13 for sewing, and the friction between the two rubber blocks 13 is used to avoid the rolling strip from slipping, thereby improving the sewing quality of the rolling strip.
