[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The embodiment of the present application discloses a tape coating and discharging device. Figure 1 、 Figure 2 、 Figure 3 A tape coating and unloading device includes a U-shaped first support plate 1, so that the first support plate 1 can stably support the entire device, and a columnar unloading roller 2, a plurality of columnar guide rollers 3, a columnar squeezing roller 4, and a columnar winding roller 5 are rotatably connected to the inner side wall of the first support plate 1. The tape base layer is rolled and fixed to the outer surface of the unloading roller 2, and one end of the tape base layer is passed through the plurality of guide rollers 3 and the squeezing roller 4, and then fixed to the outer surface of the winding roller 5. The rotation of the winding roller 5 drives the transmission of the tape base layer so that it is coated with glue;

[0021] Secondly, a box-shaped dust collection box 6 is fixedly connected to the inner wall of the first support plate 1, a negative pressure chamber 14 is fixedly connected to the side surface of the first support plate 1, and a tubular dust collection pipe 15 is fixedly connected to the lower surface of the dust collection box 6. The other end of the dust collection pipe 15 passes through the first support plate 1 to its outside and is fixedly connected to the upper surface of the negative pressure chamber 14. Under the action of the negative pressure chamber 14, the dust on the lower surface of the tape base layer passing through the dust collection box 6 is adsorbed and removed to prevent the dust from affecting the subsequent glue and tape base layer. Adhesion, and the adsorbed dust is transported to the inside of the negative pressure chamber 14 through the dust suction pipe 15 for subsequent centralized treatment, and a box-shaped glue box 7 is fixedly connected to the inner bottom surface of the first support plate 1, and a columnar glue roller 8 is rotatably connected between the squeezing roller 4 and the glue box 7 on the inner side wall of the first support plate 1, so that the glue is loaded into the glue box 7. During the transmission process of the tape base layer, the glue roller 8 is driven by the tape to rotate relative to the squeezing roller 4. During the rotation process, the glue roller 8 sticks the glue in the glue box 7 to the surface. Then, the upper glue roller 8 and the squeezing roller 4 squeeze the tape base layer, so that the glue is adhered to the lower surface of the tape base layer to complete the gluing of the tape. Secondly, a plate-shaped second support plate 9 is fixedly connected to the inner side wall of the first support plate 1, and a plurality of fans 10 are rotatably connected to the upper surface of the second support plate 9. A heating wire plate 11 is fixedly connected to the inner side wall of the first support plate 1 above the plurality of fans 10, so that the plurality of fans 10 rotate to blow air toward the heating wire plate 11, so that the hot air is blown toward The tape after gluing is accelerated to accelerate the drying speed of the glue, avoid affecting the subsequent winding of the tape, and thus improve the gluing quality of the tape. Secondly, a U-shaped plate-like moving plate 12 is slidably connected to the inner side wall of the first support plate 1, and a columnar rotating column 20 is rotatably connected to the inner side wall of the moving plate 12. The outer surface of the rotating column 20 is fixedly connected to the extrusion column 13, so that during the discharge process, the extrusion column 13 can extrude the tape base roll to avoid loosening during the discharge process and affecting the quality of the gluing.

[0022] Reference Figure 2A motor 19 is fixedly connected to the side surface of the first support plate 1. One end of the rotating shaft of the winding roller 5 passes through the first support plate 1 to its outer side and is fixedly connected to the output end of the motor 19, so that the winding roller 5 can be driven to rotate by the motor 19, thereby driving the tape base layer to be transmitted, thereby facilitating the gluing of the tape base layer.

[0023] Reference Figure 3 、 Figure 4 , groove-shaped slide grooves 16 are provided on both side surfaces of the first support plate 1, and a columnar limit column 17 is fixedly connected to the inner wall of the slide groove 16, and the outer surface of the limit column 17 slides relative to the movable plate 12, and a return spring 18 is fixedly connected to the inner bottom surface of the slide groove 16, and the upper end of the return spring 18 is fixedly connected to the lower surface of the movable plate 12. After the tape base roll is installed on the outer surface of the unloading roller 2, the tape base roll will cause the movable plate 12 to move downward. At this time, the return spring 18 is in a compressed state. Subsequently, during the unloading process, due to the reset action of the return spring 18, the return spring 18 will drive the movable plate 12 and the extrusion column 13 to move upward, so that the extrusion column 13 squeezes the tape base roll during the unloading process, thereby avoiding loosening of the tape base during the gluing process, thereby ensuring the quality of the gluing.

[0024] The implementation principle of the tape coating and unloading device in the embodiment of the present application is as follows: the tape base roll is fixed to the outer surface of the unloading roller 2, and then one end of the tape base passes through several guide rollers 3 and squeezing rollers 4 in sequence, and then is fixed to the outer surface of the take-up roller 5, and then the motor 19 drives the take-up roller 5 to rotate, thereby driving the tape base to be transmitted. After the tape base roll is installed on the outer surface of the unloading roller 2, the movable plate 12 will move downward, causing the return spring 18 to be in a compressed state all the time. Therefore, during the transmission of the tape base, under the reset action of the return spring 18, the return spring 18 will drive the movable plate 12 and the squeezing column 13 to move upward, so that the squeezing column 13 squeezes the tape base roll during the unloading process, thereby preventing the tape base from loosening during the coating process, thereby ensuring the coating The quality of the glue, and secondly, in the process of the transmission of the tape base layer, first, under the action of the negative pressure chamber 14, the dust on the lower surface of the tape base layer is adsorbed and removed through the dust collection box 6 to prevent the dust from affecting the adhesion of the subsequent glue and the tape base layer, thereby ensuring the quality of the glue coating, and then in the process of the tape base layer transmission, the upper glue roller 8 and the squeezing roller 4 are driven to rotate relative to each other. During the rotation, the upper glue roller 8 sticks the glue in the glue box 7 to the surface, and then the upper glue roller 8 and the squeezing roller 4 squeeze the tape base layer, so that the glue is stuck to the lower surface of the tape base layer, completing the gluing of the tape, and then several fans 10 rotate to blow air toward the electric heating wire plate 11, so that the hot air blows to the glued tape, thereby accelerating the drying speed of the glue, avoiding affecting the subsequent winding of the tape, and thus improving the gluing quality of the tape.
