It is equipped with second telescopic members 11 distributed at intervals, and the output ends of the second telescopic members 11 are jointly fixedly installed with a top rod 12 distributed along the length direction of the base 1. The inner bottom surface of the base 1 is fixedly installed with a limit plate 10 distributed along the inner side of the first conveyor belt 3, and the end face of the limit plate 10 away from the base 1 is set to a semicircular structure. Second mounting plates 13 are fixedly installed on both sides of the base 1, and a U-shaped movable frame 14 is slidably installed on the second mounting plate 13. The movable frame 14 passes through the second mounting plate 13 and is fixedly installed with a pressure rod 16 on one end close to the base 1. A third mounting plate 17 is fixedly installed on both sides of one end of the base 1, and a pillar 18 extending into the interval of the second conveyor belt 9 is fixedly installed on the third mounting plate 17. A bottom plate 19 is fixedly installed on the end of the pillar 18 away from the third mounting plate 17. The surface of the bottom plate 19 away from the third mounting plate 17 is fixedly installed with a sewing machine body 20, and a dust cleaning component 32 for cleaning dust at the hemming position on the curtain is provided on the bottom plate 19.
[0023] The second conveyor belts 9 are parallel to the first conveyor belts 3 , and the projection areas of the intervals between the second conveyor belts 9 and the intervals between the first conveyor belts 3 toward the bottom of the base 1 coincide.
[0024] A threaded rod 15 is rotatably mounted on the second mounting plate 13 . The threaded rod 15 passes through a horizontal section of the movable frame 14 and is threadedly connected to the movable frame 14 .
[0025] The mounting frame 7 is provided with a groove 31 for the support column 18 to pass through.
[0026] A transverse plate 21 is fixedly mounted on both sides of the base 1 . The transverse plate 21 is located inside the first conveyor belt 3 , and a support platform 22 is fixedly mounted on the transverse plate 21 and is located in the interval of the first conveyor belt 3 and is used in conjunction with the sewing machine body 20 .
[0027] When the curtain is folded, the second conveyor belt 9 is moved upward, and the curtain is folded. When the curtain is folded, the second conveyor belt 9 is moved upward, and the curtain is folded. When the curtain is folded, the second conveyor belt 9 is moved upward, and the curtain is folded. When the curtain is folded, the second conveyor belt 9 is moved downward, and the curtain is folded. When the curtain is folded, the second conveyor belt 9 is moved downward, and the curtain is folded. When the curtain is folded, the second conveyor belt 9 is moved downward, and the curtain is folded. When the curtain is folded, the second conveyor belt 9 is moved downward, and the curtain is folded. When the curtain is folded, the second conveyor belt 9 is moved downward, and the curtain is folded. When the curtain is folded, the second conveyor belt 9 is moved downward, and the curtain is folded. When the curtain is folded, the second conveyor belt 9 is moved downward, and the curtain is folded. When the curtain is folded, the second conveyor belt 9 is moved downward, and the curtain is folded. When the curtain is moved, the first conveyor belts 3 on both sides are driven to enable the curtain to move forward stably. The position of the internal components of the dust cleaning assembly 32 is adjusted so that the dust cleaning assembly 32 can contact the surface of the curtain. When the curtain moves, the dust cleaning assembly 32 cleans the dust and impurities at the hemming sewing position of the curtain and collects the dust and impurities, ensuring the cleanliness of the position when the curtain is hemming and preventing dust and impurities from affecting the sewing of the hemming position. The swept dust and impurities will be collected in the dust cleaning assembly 32. After long-term use, the dust can be removed for cleaning to achieve rapid dust cleaning. The cleaned curtain continues to move forward to the bottom of the sewing machine body 20. The sewing machine body 20 cooperates with the support platform 22 to sew the curtain. Under the action of the first conveyor belt 3 and the second conveyor belt 9, the curtain is always transported at a steady and uniform speed, thereby ensuring the stability and uniformity of the curtain hemming and improving the sewing quality of the curtain hemming. After sewing is completed, the curtain can be removed, realizing the simultaneous hemming operation of the curtain on both sides. After the curtain is placed, there is no need for subsequent manual tidying of the curtain position, thereby reducing the workload of employees, achieving stable and fast sewing during hemming, and facilitating use.
[0028] In one embodiment of the present invention, the rotating power member 4 is a motor, and of course it can also be other components that can output rotating power, such as a hydraulic motor. The motor drives the first conveyor belt 3 to rotate, thereby realizing the transportation of the curtains. The first telescopic member 6 and the second telescopic member 11 are respectively the first electric telescopic rod and the second electric telescopic rod. Of course, they can also be other components that can actively change the length, such as a hydraulic cylinder. The first electric telescopic rod drives the second conveyor belt 9 to move up and down, and the second electric telescopic rod drives the top rod 12 to move up and down, thereby realizing the tensioning of the curtains.
[0029] like Figure 1 and Figure 4As shown, as a preferred embodiment of the present invention, the dust cleaning component 32 includes a third telescopic member 23, the third telescopic member 23 is fixedly mounted on the bottom plate 19 and points to the bottom surface of the base 1, and a lifting plate 24 is fixedly mounted on the output end of the third telescopic member 23, and a plurality of groups of spaced-apart brushes 25 are fixedly mounted on the surface of the lifting plate 24 close to the first conveyor belt 3.
[0030] The dust cleaning component 32 also includes an exhaust fan 27, which is connected to a dust suction hose 28. The end of the dust suction hose 28 away from the exhaust fan 27 is connected to a dust box 26 fixedly mounted on the lifting plate 24. The dust box 26 is located on one side of the brush 25 and has multiple groups of through holes on the side of the dust box 26 close to the brush 25.
[0031] The exhaust fan 27 is connected to an exhaust pipe 29 . One end of the exhaust pipe 29 away from the exhaust fan 27 is fixed on the third mounting plate 17 . The other end of the exhaust pipe 29 away from the exhaust fan 27 is detachably connected to a cloth bag 30 .
[0032] During actual application of the embodiment of the present invention, the third telescopic member 23 drives the lifting plate 24 to move downward so that the brush 25 can come into contact with the surface of the curtain. Then, when the curtain moves, the brush 25 can clean the surface of the curtain, so that impurities and dust on the surface of the curtain can be swept up. At the same time, the exhaust fan 27 draws out the air in the dust collection box 26, so that the outside air carrying dust and impurities can enter the dust collection box 26, thereby collecting the dust swept up on the surface of the curtain and preventing the dust from falling to other positions of the curtain, ensuring the cleanliness of the position when the curtain is hemmed, and preventing dust and impurities from affecting the sewing of the hemming position. The dust is transported to the cloth bag 30 through the exhaust pipe 29, thereby realizing dust collection. After long-term use, the cloth bag 30 can be removed from the exhaust pipe 29 for cleaning.
[0033] In one embodiment of the present invention, the third telescopic member 23 is a third electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder. The third electric telescopic rod drives the brush 25 to move up and down, so that the brush 25 can contact the surface of the curtain.
[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
