[0047] A frame 1 provided between the unwinding mechanism and the coating mechanism;

[0053] The foil discharging outlet 6 is arranged on one side of the traction mechanism 5 and is used for outputting the foil input by the traction mechanism 5.

[0054] By sequentially arranging a deviation rectifying mechanism, a tensioning mechanism, and a traction mechanism from top to bottom between the foil feeding inlet and the discharging outlet, the situations of easy edge collapse and deviation of the foil can be solved, and it is ensured that the foil runs in the middle before entering the A-side coating mechanism; compared with the prior art in which a traction mechanism and a deviation rectifying mechanism need to be separately arranged and used in cooperation, the utility model can integrate the functions of the two with only one device. The structure of this device is compact, which can reduce the maintenance cost and the floor area of the device.

[0055] Refer to Figure 2 、 Figure 5 Furthermore, the deviation rectifying mechanism 3 includes a movable deviation rectifying probe 31, a deviation rectifying roller 32, a deviation rectifying table 33, a deviation rectifying execution device 34, and a hinge column 35;

[0056] The movable deviation rectifying probe 31 is arranged on one side of the foil feeding inlet 2 and is used for detecting the position of the foil;

[0057] The deviation rectifying roller 32 is rotatably arranged on the deviation rectifying table 33;

[0058] The deviation rectifying table 33 and the frame 1 are hinged through the hinge column 35;

[0059] One end of the deviation rectifying execution device 34 is hinged to the frame 1, and the other end of the deviation rectifying execution device 34 is hinged to the deviation rectifying table 33;

[0060] When the movable deviation rectifying probe 31 detects that the foil deviates during the running process, the deviation rectifying execution device 34 extends out, driving the deviation rectifying table 33 and the deviation rectifying roller 32 to rotate around the hinge column 35 to rectify the deviation of the foil on the deviation rectifying roller 32.

[0061] Refer to Figure 1 、 Figure 3, specifically, a gantry 11 is provided on the frame 1, and the mobile deviation correction probe 31 includes a sliding structure 311 and a deviation correction probe 312 provided on the gantry 11; among them, referring to Figure 6 , a slider 3110 is provided on the sliding structure 311, and the deviation correction probe 312 is fixedly connected to the slider 3110 and slides on the gantry 11 along with the slider 3110;

[0062] Among them, the sliding structure 311 can be any one of a screw drive structure, a belt drive structure or a chain drive structure; taking the screw drive structure as an example, referring to Figure 6 , the sliding structure 311 includes a slide rail 3111, a handwheel 3112, a lead screw 3113, a fixed block 3114 and a lead screw nut 3115; the slide rail 3111 is fixedly connected to the gantry 11, the fixed block 3114 is fixedly connected to one end of the slide rail 3111, the lead screw nut 3115 is slidably arranged on the slide rail 3111 and the lead screw nut 3115 is fixedly connected to the slider 3110; the lead screw 3113 sequentially rotates through the fixed block 3114, the lead screw nut 3115 and the slider 3110, and the handwheel 3112 is fixedly connected to the end of the lead screw 3113. When the position of the deviation correction probe 312 needs to be adjusted, rotate the handwheel 3112, and the handwheel 3112 drives the lead screw 3113 to rotate, so that the lead screw nut 3115 drives the slider 3110 to slide on the slide rail 3111 to adjust the relative position between the deviation correction probe 312 and the foil.

[0063] Referring to Figure 4 , more specifically, the deviation correction roller 32 is an exhaust roller, and a plurality of exhaust grooves 321 are provided on the upper surface of the exhaust roller along the axial direction of the exhaust roller; in the case of high-speed running of the foil, an air layer will be generated between the foil and the roller surface of the deviation correction roller 32. The exhaust grooves 321 are provided to allow the gas in the air layer to exhaust axially along both ends of the deviation correction roller 32, so that the foil is closely attached to the deviation correction roller 32, increasing the friction between the foil and the deviation correction roller 32 and reducing the deviation of the foil.

[0064] Referring to Figure 5 , more specifically, the deviation correction table 33 is a hollow square deviation correction table, and the hinge column 35 and the deviation correction execution device 34 are arranged on the opposite inner walls of the square deviation correction table.

[0065] Referring to Figure 1 , Figure 3 , further, the tensioning mechanism 4 includes a swing roller 41, a swing arm driving member 42, a swing arm 43 and a tension roller 44;

[0066] One end of the swing arm 43 is hinged to the frame 1, and the other end of the swing arm 43 is connected to the end of the swing roller 41; the fixed end of the swing arm drive 42 is arranged on the frame 1, and the output end of the swing arm drive 42 is connected to the swing arm 43;

[0067] The swing arm drive 42 extends or retracts to drive the swing roller 41 to swing with the swing arm 43 as the rotation radius, so as to control the tension of the foil;

[0068] The tension roller 44 is arranged on one side of the swing roller 41 for detecting the tension of the foil transmitted through the swing roller 41.

[0069] Refer to Figure 1 , for further explanation, the frame 1 has two relatively arranged inner walls of the frame, and the tensioning mechanism 4 and the traction mechanism 5 are both arranged on the inner walls of the frame; that is to say, there can be two swing arms 43 hinged to the frame 1, and both of the swing arms 43 are hinged to the inner walls of the frame. At this time, each end of the swing roller 41 is connected to a swing arm 43. In this way, when tensioning the foil, it helps to balance the tension of the foil at both ends of the swing roller 41 and avoid the deviation of the foil.

[0070] Specifically, the swing arm drive 42 can be a cylinder;

[0071] Specifically, the tensioning mechanism 4 further includes a PLC controller, and the PLC controller is electrically connected to the detection end of the tension roller 44 and the control end of the swing arm drive 42 respectively; during the process of tape running, the foil passes through the tension roller 44, and the tension roller 44 monitors the real-time tension of the foil and feeds it back to the PLC controller; the PLC controller compares the real-time tension of the foil with the programmed tension and feeds it back to the cylinder, and the cylinder extends or retracts to realize the adjustment of the foil tension.

[0072] Refer to Figure 3 , further, the traction mechanism 5 includes a pressure roller 51, an L-shaped pressure roller swing arm 52, a pressure roller swing arm hinge 53, a pressure roller swing arm drive 54, a traction roller 55 and a traction roller drive;

[0073] The fixed end of the traction roller drive is arranged on the frame 1 and the output end is connected to any end of the traction roller 55, and the traction roller drive outputs torque to drive the traction roller 55 to rotate;

[0074] The L-shaped pressure roller swing arm 52 is arranged on the frame 1 through the pressure roller swing arm hinge 53, the fixed end of the pressure roller swing arm drive 54 is hinged to the frame 1, and the output end of the pressure roller swing arm drive 54 is connected to one end of the L-shaped pressure roller swing arm 52; the pressure roller 51 is rotatably arranged at the other end of the L-shaped pressure roller swing arm 52;

[0075] The pressing roller swing arm driving member 54 extends or retracts to drive the pressing roller 51 to rotate around the pressing roller swing arm hinge member 53, so as to press the foil material onto the surface of the traction roller 55.

[0076] When the pressing roller swing arm driving member 54 extends to press the foil material between the pressing roller 51 and the traction roller 55, the setting of the traction roller driving member provides power for the foil material and realizes the tension isolation of the foil material, facilitating the operation of the A-side coating mechanism.

[0077] Specifically, the pressing roller swing arm driving member 54 is a cylinder.

[0078] Refer to Figure 3 , further, it further includes a first guide roller 7 and a second guide roller 8. The first guide roller 7 is arranged between the tensioning mechanism 4 and the traction mechanism 5 for guiding the foil material output from the tensioning mechanism 4 to the traction mechanism 5; the second guide roller 8 is arranged between the traction mechanism 5 and the foil material running tape outlet 6 for guiding the foil material output from the traction mechanism 5 to the A-side coating mechanism.
