Technical Field

[0001] The utility model relates to the technical field of waterproof coiled material production, in particular to a base cloth preheating structure for waterproof coiled material production. Background Art

[0002] There are many production processes for waterproof membranes. In the initial stage, the rolled base cloth needs to be unfolded and preheated by a preheating structure before being transported to the subsequent dipping process. After the base cloth is preheated by the preheating structure, the base cloth can be drier, which facilitates better coating of asphalt on the base cloth in the subsequent dipping process.

[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0020] like Figure 2 and Figure 3 As shown, the utility model provides a preheating structure for base fabric used in the production of waterproof coiled materials, comprising a frame 10, a preheating box 20, a middle opening member 30, an upper moving member 40 and a lower moving member 50;

[0021] The preheating box 20 is arranged in the middle of the frame 10, a heating structure is arranged in the preheating box 20, and the preheating box 20 has an upper narrowing section 2 and a lower narrowing section 3;

[0022] The middle opening member 30 is arranged on both sides of the middle of the preheating box 20. The middle opening member 30 includes a driving part 310 and two opening rollers 31. The two opening rollers 31 are respectively located in the arc-shaped openings 23 on both sides of the middle of the preheating box 20. The driving part 310 is used to drive the two opening rollers 31 to move.

[0023] The upper moving member 40 is disposed at the upper end of the frame 10, and the upper moving member 40 includes a first driving member 410, a first upper conveying roller 41, and a second upper conveying roller 42. Both ends of the first upper conveying roller 41 and the second upper conveying roller 42 are movably disposed in upper guide grooves 43 on both sides of the upper end of the frame 10, respectively. The first driving member 410 is used to drive the two upper conveying rollers to move closer to or away from each other.

[0024] The lower moving member 50 is arranged at the lower end of the frame 10, and the lower moving member 50 includes a second driving member 510, a first lower conveying roller 51 and a second lower conveying roller 52. Both ends of the first lower conveying roller 51 and the second lower conveying roller 52 are movably arranged in the lower guide grooves 53 on both sides of the lower end of the frame 10, and the second driving member 510 is used to drive the two lower conveying rollers to move closer to or away from each other.

[0025] During the working process, the tire base fabric 8 is sequentially conveyed from the first lower conveying roller 51, the first upper conveying roller, the second upper conveying roller 42, and the second lower conveying roller 52. The tire base fabric 8 will be close to the side walls of the preheating box 20 and preheat the tire base fabric 8. When the subsequent process pauses or an emergency occurs, the first driving member 410 drives the two upper conveying rollers to move away from each other in the upper guide groove 43, and then the driving part 310 drives the two opening rollers 31 to move inward and outward from the arc-shaped opening 23. Subsequently, the second driving member 510 drives the two lower conveying rollers to move away from each other in the lower guide groove 53, so that the tire base fabric 8 is respectively away from the side walls of the upper narrowing section 2, the middle and the lower narrowing section 3 of the preheating box 20, thereby solving the problem of excessive preheating of the tire base fabric 8.

[0026] To further explain, since the upper end of the preheating box 20 is the upper narrowing section 21 and the lower end is the lower narrowing section 22, when only the middle expansion member 30 is provided, the tire base cloth 8 will still be in close contact with the upper narrowing band 21 and the lower narrowing section 22 on both sides. If only the upper moving member 40 and the lower moving member 50 are provided, the distance between the tire base cloth 8 on both sides of the middle of the preheating box 20 is still small, which causes the tire base cloth 1 on both sides of the middle of the preheating box 20 to be preheated heavier than the tire base cloth 8 on both sides of the upper and lower ends of the preheating box 20.

[0027] Preferably, the driving part 310 includes two L-shaped rods 311, a driving rod 312 and a cylinder 313, the middle parts of the two L-shaped rods 311 are rotatably connected to the preheating box 20, the upper ends of the two L-shaped rods 311 are rotatably connected to the two ends of the driving rod 312, and the lower ends of the two L-shaped rods 311 are rotatably connected to the two ends of the two expansion rollers 31. The driving part 310 has two groups, and the two groups of the driving parts 310 are respectively arranged at the two ends of the preheating box 20.

[0028] The cylinder 313 drives the driving rod 312 to move up or down. The driving rod 312 moves up to drive the L-shaped rod 311 to rotate, and the L-shaped rod 311 drives the expansion roller 31 to move into the arc-shaped opening 23. When the driving rod 312 moves down, it drives the two L-shaped rods 311 to rotate, and the L-shaped rod 311 drives the expansion roller 31 to move inside and outside the arc-shaped opening 23, so that the tire base cloth 8 on both sides of the middle part of the preheating box 20 is expanded outward.

[0029] Preferably, the first driving member 410 and the second driving member 510 both include a screw rod 511 and two moving blocks 513. The screw rod 511 in the first driving member 410 is arranged in the upper guide groove 43, and the screw rod 511 in the second driving member 510 is arranged in the lower guide groove 53. The screw rod 511 has a positive rotation section 514 and a reverse rotation section 515. The two moving blocks 513 are respectively arranged on the positive rotation section 514 and the reverse rotation section 515. The two upper conveying rollers are respectively arranged on the two moving blocks 513 at the upper end of the frame 10, and the two lower conveying rollers are respectively arranged on the two moving blocks 513 at the lower end of the frame 10.

[0030] The motor drives the screw rod 511 to rotate, thereby rotating the positive rotating section 514 and the reverse rotating section 515, and the two moving blocks 513 will move closer to or farther away from each other. When the two moving blocks 513 move away from each other, the two upper conveying rollers or the two lower conveying rollers move away from each other. When the two moving blocks 513 move closer to each other, the two upper conveying rollers or the two lower conveying rollers move closer to each other.

[0031] Preferably, the upper guide grooves 43 are respectively provided on the upper side plates 18 on both sides of the upper end of the frame 10 , and the lower guide grooves 53 are respectively provided on the lower side plates 19 on both sides of the lower end of the frame 10 .

[0032] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
