BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 2 It is the structure schematic diagram of the utility model.

[0013] In the figure, 1 is driven sprocket, 2 is driving sprocket, 3 is brake motor, 4 is tensioning sprocket set, 5 is no material detection support, 6 is discharging detection support, 7 is material thickness detection support, 8 is material blocking plate, 9 is discharging rack Specific implementation

[0014] A novel driving feeding device, the feeding device includes driven sprocket 1, driving sprocket 2, brake motor 3, tensioning sprocket set 4, no material detection support 5, discharging detection support 6, material thickness detection support 7, material blocking plate 8 and discharging rack 9;

[0015] Driven sprocket 1 is fixed on the material carrying shaft of discharging rack 9 through a set screw, the material carrying shaft is placed with coiled material, driving sprocket 2 is arranged on brake motor 3, driven sprocket 1 is connected with driving sprocket 2 through a chain, material blocking plate 8 is arranged on the discharging side of discharging rack 9, no material detection support 5 is arranged above the material carrying shaft, discharging detection support 6 is arranged on one side of discharging rack 9, and material thickness detection support 7 is arranged below discharging rack 9.

[0016] Tensioning sprocket set 4 is arranged at the chain at the middle position between driven sprocket 1 and driving sprocket 2 to prevent the loosening of the sprocket.

[0017] No material detection support 5 is provided with a photoelectric switch, and a reflector is arranged below the photoelectric switch.

[0018] Discharging detection support 6 is provided with a photoelectric switch.

[0019] Material thickness detection support 7 is provided with a detection switch, and the thickness of the coiled material is analyzed by the distance of signal emission of the detection switch.

[0020] Driven sprocket 1 is fixed on the material carrying shaft of discharging rack 9 through a set screw, and the material carrying shaft is provided with the coiled material required by the manufacturer. Driving sprocket 2 is installed on brake motor 3 through a clamping device, and driven sprocket 1 and driving sprocket 2 are connected through a chain. In order to prevent the loosening of the sprocket, tensioning sprocket set 4 is arranged at the middle height position to tighten the chain. Brake motor 3 has high transmission efficiency, and the transmission loss can be ignored.

[0021] In order to better monitor the use of the coiled material, reduce the resource consumption of manual visual inspection, a plurality of detection switches are arranged. The photoelectric switch in the empty material detection support 5 is provided with a reflector vertically below. Once the coiled material is used up, the photoelectric switch will receive the reflected electric signal, and the system will identify that the coiled material is used up, and the machine needs to be stopped immediately to replace the coiled material.

[0022] The photoelectric switch is also arranged in the empty material detection support 6. The excess coiled material after the uncoiling of the empty material frame 9 will naturally droop and block the photoelectric switch, proving that the emptying speed is faster than the pulling speed, and the emptying can be stopped. Once the empty material detection photoelectric switch receives the photoelectric signal, it is proved that the material line is higher than the set value, and the remaining material after uncoiling is insufficient, so the brake motor 3 needs to be started to begin emptying.

[0023] The material thickness detection support 7 is installed directly below the coiled material, and the thickness of the material is analyzed according to the distance of the detection switch signal transmission, so as to serve as the basis for controlling the emptying frequency.

[0024] The material blocking plate 8 is installed on the discharging side of the empty material frame 9, to prevent the material from being abnormally wound into the empty material frame 9 in an emergency.
