[0013] In order to further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to detail the specific embodiments, structures, features and their effects of the present utility model as follows.

[0014] As Figures 1 - 3 shown, the present utility model discloses an automatic feeding device for a glass fiber cloth edge sewing machine, which includes a substrate 1. A vertical shaft 2 is provided at one end of the substrate 1. A first motor 3 is provided at the lower end of the substrate 1. The first motor 3 is drivingly connected to the vertical shaft 2. A turntable 4 is provided on the vertical shaft 2. A material tray 5 is fixed on the turntable 4, and an edge sewing cloth 17 is wound on the material tray 5; A second motor 6 is provided at the other end of the substrate 1. The output shaft of the second motor 6 is vertically upward. A pressure wheel 7 is provided on the output shaft of the second motor 6. An arc-shaped guide groove 8 with a V-shaped cross section is provided on the substrate 1 on the side of the pressure wheel 7. The edge of the pressure wheel 7 is located in the arc-shaped guide groove 8; The edge sewing cloth 17 passes through between the arc-shaped guide groove 8 and the pressure wheel 7 to form a V-shaped cloth strip for edge sewing of the glass fiber cloth.

[0015] The vertical shaft 2 is rotatably connected to the substrate 1 and is driven to rotate by the first motor 3, and its rotation speed is controlled by the first motor 3. The turntable 4 and the material tray 5 on the vertical shaft 2 can rotate together, and the central axes of the turntable 4, the material tray 5 and the vertical shaft 2 coincide; the edge-sewing cloth 17 is wound around the material tray 5 and supported on the turntable 4. The edge-sewing cloth 17 output from the material tray 5 is conveyed into the arc-shaped guide groove 8 and is driven forward by the pressing wheel 7 on the second motor 6. The arc-shaped guide groove 8 and the pressing wheel 7 cooperate to press the edge-sewing cloth 17 into a V-shaped structure. The conveying speeds of the first motor 3 and the second motor 6 are reasonably controlled to keep the edge-sewing cloth 17 conveyed stably. This form conveys the edge-sewing cloth 17 more stably and reliably. The pressing wheel 7 and the arc-shaped guide groove 8 can stably press the edge-sewing cloth 17 into a V-shaped structure, and it is not easy to have situations such as the deviation of the edge-sewing cloth 17 during the edge-sewing process, improving the edge-sewing quality.

[0016] The first motor 3 and the second motor 6 are located at both ends of the substrate 1 in the length direction. Two slide rails 10 are arranged at intervals on the substrate 1 between the first motor 3 and the second motor 6. The slide rails 10 are arranged along the width direction of the substrate 1. A slider 11 is arranged on each slide rail 10, and a tensioning wheel 12 is arranged on the slider 11. An installation plate 14 is arranged on the substrate 1 at one end of each slide rail 10. A tension spring 15 is arranged between the installation plate 14 and the corresponding slider 11. The tension springs 15 corresponding to the two slide rails 10 are respectively located at opposite ends of the slide rails 10. In order to further keep the edge-sewing cloth 17 in a tensioned state during the conveying process, two slide rails 10 are arranged along the width direction of the substrate 1 between the first motor 3 and the second motor 6. A slider 11 is arranged on each slide rail 10 and tension springs 15 are arranged at opposite ends. The tensioning wheel 12 is arranged on the slider 11. After the edge-sewing cloth 17 is output from the material tray 5, it bypasses the tensioning wheel 12 and then is fed into the arc-shaped guide groove 8. In this process, the tension springs 15 apply forces in opposite directions to the two sliders 11, thereby tensioning the edge-sewing cloth 17. The tensioned edge-sewing cloth 17 can better maintain stable conveying, and the process of folding into a V-shaped structure is also more stable and reliable.

[0017] Both the upper and lower ends of the tension pulley 12 protrude outward to form an annular limit step 13, and the distance between the limit steps 13 at both ends of the same tension pulley 12 is equal to the width of the edge-sewing cloth 17; the upper surface of the turntable 4 is on the same horizontal plane as the upper surface of the limit step 13 at the lower end of the tension pulley 12. By providing the limit steps 13 at both the upper and lower ends of the tension pulley 12, when the edge-sewing cloth 17 cooperates with the tension pulley 12, the position of the edge-sewing cloth 17 can be effectively restricted to ensure that it maintains a stable height and does not shift in height. Since the lower surface of the edge-sewing cloth 17 on the material tray 5 is supported on the turntable 4, and when the edge-sewing cloth 17 cooperates with the tension pulley 12, its lower surface contacts the upper surface of the lower limit step 13 of the tension pulley 12, so the upper surface of the turntable 4 is on the same horizontal plane as the upper surface of the lower limit step 13 of the tension pulley 12, then the edge-sewing cloth 17 can also maintain the same horizontal position during the conveying process, with high overall stability and not prone to position shift.

[0018] Guide rollers 16 are provided on the substrate 1 between the first motor 3 and the tension pulley 12 close to it, and guide rollers 16 are also provided on the substrate 1 between the second motor 6 and the tension pulley 12 close to it. The guide rollers 16 are all rotatably connected to the substrate 1, and the axial direction of the guide rollers 16 is the vertical direction. By providing the guide rollers 16 on the substrate 1 outside the two tension pulleys 12, it can be ensured that both the output process of the edge-sewing cloth 17 and the process of entering the arc-shaped guide groove 8 are stable and reliable, the angle is basically stable, and it is avoided that the output angle of the edge-sewing cloth 17 and the angle of the edge-sewing cloth 17 entering the arc-shaped guide groove 8 change due to the change of the position of the tension pulley 12, resulting in the reduction of conveying stability, and the operation reliability is improved.

[0019] The arc-shaped guide groove 8 is fixed to the substrate 1 through a column 9, and the height of the arc-shaped guide groove 8 corresponds to the height of the turntable 4.

[0020] The arc-shaped guide groove 8 is arranged in an overall horizontal state. The fact that the height of the arc-shaped guide groove 8 corresponds to the height of the turntable 4 means that the middle part of the V-shaped structure of the arc-shaped guide groove 8 is at the same height as the middle position in the width direction of the edge-sewing cloth 17 on the turntable 4 and the tension pulley 12. In this way, during the conveying process, the edge-sewing cloth 17 can always maintain horizontal movement without position offset, so it is more stable when entering the arc-shaped guide groove 8, and it is also more stable and reliable when folded into a V-shaped structure.
