DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0033] like Figures 1 to 4As shown, a cloth strip conveying device for a flat sewing machine provided by an embodiment of the utility model comprises a workbench 1 and a cloth rolling rod 2. Two support plates 21, two cleaning frames 22 and a stabilizing plate 23 are fixedly connected to the upper end surfaces of the workbench 1 respectively. A driving shaft 24 is rotatably connected between the two support plates 21. The two support plates 21 can support the driving shaft 24 to ensure the stability of the driving shaft 24. A driving roller 25 is fixedly connected to the outer wall of the driving shaft 24. A driven roller 26 is arranged above the driving roller 25. Through the cooperation of the driving roller 25 and the driven roller 26, the cloth is conveyed. Two symmetrical rotating rods 27 are rotatably connected between the two cleaning frames 22. A sticky brush 28 is fixedly connected to the outer wall of the rotating rod 27. A positioning plate 29 is fixedly connected to one side of a cleaning frame 22, and a rotating motor 30 is fixedly connected to the upper end surface of the positioning plate 29. The positioning plate 29 can fix the rotating motor 30 to ensure the stability of the rotating motor 30. The output end of the rotating motor 30 is connected to one of the rotating rods 27. One end of the two rotating rods 27 is fixedly connected to a gear 31. The two gears 31 are meshed with each other. Through the rotation of the rotating motor 30, the two gears 31 can be meshed with each other, so that the fluff and thread ends on the surface of the cloth can be cleaned. A positioning rod 41 is rotatably connected to the driven roller 26. Both ends of the positioning rod 41 are fixedly connected to a fixed block 42. The upper end surface of the fixed block 42 is fixedly connected to an electric telescopic column 43. The electric telescopic column 43 is far A stabilizing frame 44 is fixedly connected to one end of the fixed block 42, and the stabilizing frame 44 is fixedly connected to the support plate 21. Through the action of two electric telescopic columns 43, the use height of the driven roller 26 can be adjusted to control the distance between the active roller 25 and the driven roller 26. A retaining plate 61 is fixedly connected to one side of one of the support plates 21, and a driving motor 62 is fixedly connected to the upper surface of the fixed plate. The retaining plate 61 can fix the driving motor 62 to ensure the stable output of the driving motor 62. The output end of the driving motor 62 is connected to the driving shaft 24, and the driving motor 62 is rotated to provide power output for the active roller 25. A connecting plate 51 is fixedly connected to one side of the two support plates 21, and a total of 100 parts are provided between the two connecting plates 51. The guide rod 52 is fixedly connected to the cloth, and the guide roller 53 is rotatably connected to the outer wall of the guide rod 52. The use of the guide rod 52 and the guide roller 53 can guide and convey the cloth, increase the tension during the cloth conveying process, and prevent the cloth from wrinkling. The cloth-winding rod 2 is fixedly connected to the stabilizing plate 23, and a cloth-winding disc 71 is fixedly connected to the outer wall of the cloth-winding rod 2. The end of the cloth-winding rod 2 away from the stabilizing plate 23 is screwed to a limiting rod 81. The cooperation of the cloth-winding disc 71 and the limiting rod 81 limits the cloth to ensure the stability of the cloth. At the same time, the screw connection between the limiting rod 81 and the cloth-winding rod 2 can facilitate the replacement of the cloth. Support legs 91 are fixedly connected to the four corners of the lower end surface of the workbench 1, and the four support legs 91 can support and fix the entire conveying device.

[0034] The working principle and use process of the utility model are as follows: when in use, first, the cloth to be used is mounted on the cloth rolling rod 2, and the cloth is limited by screwing the limiting rod 81 with the cloth rolling rod 2, and then the cloth passes through the two sticky brushes 28, passes under the guide roller 53, and finally passes between the active roller 25 and the driven roller 26, and cooperates with the action of the driving motor 62 to rotate the active roller 25 to convey the cloth, and the driven roller 26 follows the movement of the auxiliary cloth, and the two electric telescopic columns 43 can adjust the distance between the driven roller 26 and the active roller 25. During the conveying process, the rotation of the rotating motor 30 causes the gear 31 on one of the rotating rods 27 to mesh with the other gear 31, so that the two sticky brushes 28 rotate in the opposite direction to clean the cloth, thereby realizing the use process of the entire cloth strip conveying device.
