[0012] The working principle and beneficial effects of the utility model are:
[0013] In order to control the amount of glue applied and ensure the uniformity of glue application, a glue roller is used for glue application. The bottom of the glue roller is immersed in the glue storage box, the surface is covered with glue, and the top is against the surface of the bottom layer. As the bottom layer is conveyed forward, the glue roller rotates accordingly, so that the part covered with glue is constantly in contact with the bottom layer surface, and glue is applied in a face-to-face contact manner, thereby ensuring the uniformity of glue application. Because the glue roller rotates along with the bottom layer conveying, it is easier to control the amount of glue applied. In addition, in order to avoid the problem that the glue roller cannot ensure close contact with the bottom layer surface everywhere due to the large area of the glue roller, multiple glue rollers are arranged on the rotating shaft to reduce the contact area between the glue roller and the bottom layer, so that each glue roller can be in relatively close contact with the bottom layer surface. In addition, in order to ensure that glue can be applied to all parts of the bottom layer surface, multiple rotating shafts are arranged, and the glue rollers on the multiple rotating shafts are staggered, that is, they are staggered left and right along the conveying direction of the bottom layer. Such an arrangement allows different glue rollers to apply glue to all parts of the bottom layer surface, ensuring that glue can be applied to all parts of the bottom layer surface, thereby ensuring the uniformity of overall glue application. The bonding rollers are two rollers rotating in opposite directions with a gap between them. The gap is used to pass the surface layer and the bottom layer. The surface layer and the bottom layer coated with glue enter the gap between the bonding rollers together and are pressed by the bonding rollers to bond them together to form a composite layer.

[0023] Reference Figure 1~Figure 3, which is the first embodiment of the utility model, proposes a bonding device for reinforcing tape processing, which is used for bonding a bottom layer A and a surface layer B, including a frame 1, a gluing device and a bonding pair of rollers 2, wherein the gluing device includes a glue storage box 3, a rotating shaft 4 and a glue coating roller 5, wherein the glue storage box 3 is arranged on the frame 1 for storing glue, the rotating shaft 4 is rotatably arranged on the frame 1, the glue coating roller 5 is arranged on the rotating shaft 4, the glue coating roller 5 is multiple, the glue coating roller 5 is immersed in the glue storage box 3 and abuts against the surface of the bottom layer A, and is used for coating glue on the surface of the bottom layer A, the rotating shaft 4 is multiple, and the glue coating rollers 5 on the multiple rotating shafts 4 are staggered, the bonding pair of rollers 2 is rotatably arranged on the frame 1, the surface layer B and the bottom layer A after gluing pass through the bonding pair of rollers 2 together, and are used for bonding as a whole to form a composite layer C.
[0024] In this embodiment, in order to control the amount of glue applied and ensure the uniformity of glue application, a glue roller 5 is used for glue application. The bottom of the glue roller 5 is immersed in the glue storage box 3, the surface is covered with glue, and the top is in contact with the surface of the bottom layer A. As the bottom layer A is transported forward, the glue roller 5 rotates accordingly, so that the part covered with glue is constantly in contact with the surface of the bottom layer A, and the glue is applied in a surface-to-surface contact manner, thereby ensuring the uniformity of glue application. Because the glue roller 5 rotates along with the transportation of the bottom layer A, it is easier to control the amount of glue applied. In addition, in order to avoid the problem that the area of the glue roller 5 is too large to ensure that it is in close contact with the surface of the bottom layer A everywhere, multiple glue rollers 5 are arranged on the rotating shaft 4 to reduce the contact area between the glue roller 5 and the bottom layer A, so that each glue roller 5 can be in relatively close contact with the surface of the bottom layer A. In order to ensure that glue can be applied everywhere on the surface of the bottom layer A, multiple rotating shafts 4 are provided. The glue-applying rollers 5 on the multiple rotating shafts 4 are staggered, that is, they are staggered left and right along the conveying direction of the bottom layer A. This arrangement allows different glue-applying rollers 5 to apply glue to different parts of the surface of the bottom layer A, ensuring that glue can be applied to all parts of the surface of the bottom layer A, thereby ensuring the uniformity of the overall glue application. The bonding rollers 2 are two rollers rotating in opposite directions, with a gap between the two rollers. The gap is used to pass the surface layer B and the bottom layer A. The surface layer B and the bottom layer A with glue applied on the surface enter the gap between the bonding rollers 2 together, and are subjected to the pressing force of the bonding rollers 2, thereby being bonded together to form a composite layer C.
[0025] It also includes a sliding frame 6, a tensioning roller 7 and a spring 8. The sliding frame 6 is slidably arranged on the frame 1, and the tensioning roller 7 is rotatably arranged on the sliding frame 6. Both ends of the spring 8 act on the sliding frame 6 and the frame 1 respectively, so as to provide the tensioning roller 7 with a force to press the bottom layer A onto the glue coating roller 5.
[0026] In this embodiment, in order to ensure close contact between the bottom layer A and the glue coating roller 5, a tension roller 7 is further provided, and the elastic force provided by the spring 8 makes the sliding frame 6 always move in the direction close to the bottom layer A, so that the tension roller 7 is always pressed against the bottom layer A. There are preferably two glue coating rollers 5, the glue coating roller 5 is located below the bottom layer A, and the tension roller 7 is located above the bottom layer A and between the two glue coating rollers 5, pressing the bottom layer A downward, thereby increasing the contact area between the bottom layer A and the glue coating roller 5, and making the bottom layer A and the glue coating roller 5 more closely contacted.
[0027] It also includes a beating plate 9, which is swingably arranged on the frame 1. After the beating plate 9 is swung, it is used to intermittently beat the composite layer C.
[0028] There are multiple clapping plates 9, and the multiple clapping plates 9 are coaxially arranged.
[0029] In this embodiment, in order to ensure the sufficient adhesion between the surface layer B and the bottom layer A, a beating plate 9 is also arranged behind the bonding roller 2. The surface layer B and the bottom layer A can be more fully combined by the beating plate 9 intermittently beating the composite layer C, thereby ensuring the bonding strength and the quality level of the composite layer C. The beating plate 9 is made of a flexible material to avoid damaging the composite layer C. In order to ensure the tightness of the contact between the beating plate 9 and the composite layer C, the beating plate 9 is designed to be multiple independent, and the multiple beating plates 9 are coaxially arranged. Because the contact area between a single beating plate 9 and the composite layer C is small, the tightness of the contact with the composite layer C can be better ensured. The multiple beating plates 9 correspond to different positions of the composite layer C, respectively, so as to ensure that all parts of the composite layer C can be beaten.
[0030] It also includes a cam 10 and a spring 11. The cam 10 is rotatably arranged on the frame 1. After the cam 10 rotates, it drives the flapping plate 9 to swing away from the composite layer C. The two ends of the spring 11 act on the flapping plate 9 and the frame 1 respectively, so as to provide a force for the flapping plate 9 to approach the composite layer C.
[0031] In this embodiment, in order to drive the intermittent swing of the flapping plate 9, a cam 10 and a spring 11 are provided. The cam 10 can be driven to rotate by a motor. After the cam 10 rotates, it intermittently moves the flapping plate 9. After the cam 10 is out of contact with the flapping plate 9, the flapping plate 9 quickly hits the composite layer C under the action of the elastic potential energy accumulated by the spring 11. As the cam 10 continues to rotate, the flapping plate 9 repeats the above action.
[0032] It also includes a guide roller 12, which is rotatably arranged on the frame 1. There are multiple guide rollers 12, and the composite layer C passes through the multiple guide rollers 12 in sequence along a serpentine shape.
[0033] The shape of the flapping plate 9 matches the contour of the guide roller 12 , and the flapping plate 9 is swung to fit or cancel the fit on the surface of the guide roller 12 .
[0034] In this embodiment, the composite layer C is made to pass through a plurality of guide rollers 12 in a serpentine shape, thereby increasing the contact area with the guide rollers 12, and the flapping plate 9 is designed to be in a shape that matches the contour of the guide rollers 12. In this way, the contact area between the flapping plate 9 and the composite layer C can be increased after the flapping plate 9 swings, thereby improving the flapping effect.
[0035] It also includes a fan 13 and a winding roller 14, wherein the fan 13 is disposed on the frame 1, and the fan 13 faces the composite layer C. There are multiple fans 13, and the winding roller 14 is rotatably disposed on the frame 1 for winding the composite layer C. The fan 13 is located between the flapping plate 9 and the winding roller 14.
[0036] In this embodiment, in order to increase the solidification speed of the rubber, a fan 13 is also arranged between the beating plate 9 and the winding roller 14. The composite layer C is basically formed after beating, and then multiple fans 13 are used to blow air to the surface of the composite layer C to accelerate the surface air flow speed and help the rubber to solidify. Finally, the composite layer C is wound up by the winding roller 14.
[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
