Waterproof roll surface film covering device

Abstract

The utility model relates to the field of waterproof coiled material processing, in particular to a waterproof coiled material surface film covering device. According to an existing film covering device, the situation that a waterproof roll and a protective film are misplaced and not aligned easily occurs in the film covering process, the protective film is obliquely attached, and the waterproof performance of the waterproof roll is reduced. A waterproof roll surface film covering device comprises two supporting frames and the like. A driving conveying roller is rotationally connected between the two supporting frames, a driven conveying roller is rotationally connected between the two supporting frames, and a conveying belt is wound between the driven conveying roller and the driving conveying roller. When the waterproof coiled material is coated with a film, due to the fact that the two blocking rod frames limit the two sides of the containing rod and the two limiting rods limit the two sides of the waterproof coiled material, the protective film on the containing rod and the waterproof coiled material can be always kept in an aligned state, and the protective film is not prone to being attached obliquely.

DETAILED DESCRIPTION

[0015] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0016] Embodiment 1: A waterproofing membrane surface coating device, such as Figure 1-Figure 3As shown, it includes two support frames 1, an active conveying roller 2 is rotatably connected between the two support frames 1, a driven conveying roller 3 is rotatably connected between the two support frames 1, a conveying belt 4 is wound between the driven conveying roller 3 and the active conveying roller 2, one of the support frames 1 is fixedly connected to a motor 5 on the side close to the active conveying roller 2, the output shaft of the motor 5 is connected to the active conveying roller 2, a pressure roller 6 is rotatably connected between the two support frames 1, the end of the pressure roller 6 away from the motor 5 is fixedly connected to a gear 1 7, the end of the active conveying roller 2 away from the motor 5 is fixedly connected to a gear 2 8, the gear 2 8 is meshed with the gear 1 7, and an extrusion coating mechanism is provided on the two support frames 1, and the extrusion coating mechanism is used to extrude the protective film downward onto the waterproof membrane and coat it.

[0017] The extrusion coating mechanism includes a support plate 9, which is fixedly connected between the two support frames 1. The upper surface of the support plate 9 contacts the lower surface of the conveyor belt 4. A sliding frame 10 is slidably connected to each of the support frames 1. A pressure spring 11 is connected between the sliding frame 10 and the support frame 1. A clamping seat 12 is fixedly connected to the upper end of each of the sliding frames 10, and a placing rod 13 is placed between the two clamping seats 12.

[0018] The placement rod 13 is provided with two convex rings.

[0019] It also includes four round rods 14, two of the round rods 14 form a group, and each group of two round rods 14 is slidably connected with a bent rod 15. Two of the bent rods 15 form a group, and a return spring 16 is connected between each bent rod 15 and the support plate 9. A limiting rod 17 is fixedly connected between each group of two bent rods 15, and a blocking rod frame 18 is fixedly connected between each group of two bent rods 15.

[0020] A protrusion is provided on one side of each of the blocking rod frames 18 close to the placement rod 13 , and the protrusions on the two blocking rod frames 18 are in contact with two ends of the placement rod 13 respectively.

[0021] In the actual laminating process, the operator needs to apply a layer of protective film to the surface of the waterproof coiled material. The operator first takes out the placement rod 13 from the holder 12, then puts a roll of protective film on the middle of the placement rod 13, and the two convex rings on the placement rod 13 limit the two sides of the protective film, and then clamps the placement rod 13 with the protective film into the holder 12, and the two stop rod frames 18 limit the two sides of the placement rod 13, and then the operator starts the motor 5, and the motor 5 drives the active conveying roller 2 to rotate, and the active conveying roller 2 passes through the conveying The belt 4 drives the driven conveyor roller 3 to rotate together, and then the operator needs to place the waterproof coiled material on the conveyor belt 4 from one side of the driven conveyor roller 3, and make the two sides of the waterproof coiled material contact with the two limit rods 17 respectively. The two limit rods 17 limit the two sides of the waterproof coiled material. The conveyor belt 4 will drive the waterproof coiled material to move toward the active conveyor roller 2, and then the waterproof coiled material will contact the protective film on the placement rod 13, and squeeze the placement rod 13 and the protective film to move upward, the pressure spring 11 is stretched, and the support plate 9 will press the waterproof coiled material and the conveyor roller 2. The belt 4 is supported so that the waterproof coiled material is not easy to sink during the extrusion coating. As the conveyor belt 4 continues to drive the waterproof coiled material to move, the protective film on the placement rod 13 will be driven to rotate together, so that the protective film is attached to the waterproof coiled material. Then the rotation of the active conveyor roller 2 will drive the gear 2 8 to rotate, and the rotation of the gear 2 8 will drive the gear 1 7 and the pressure roller 6 to rotate. Then, when the waterproof coiled material contacts the pressure roller 6, the pressure roller 6 will roll the coated waterproof coiled material to a certain extent, and the rotation of the pressure roller 6 will drive the coated waterproof coiled material to rotate. The roll material moves, and the waterproof roll material that has completed the coating will be sent out from one side of the active conveying roller 2. When the waterproof roll material or the placement rod 13 and the protective film move horizontally perpendicular to the conveying direction during the coating process, the limiting rod 17 and the blocking rod frame 18 will be driven to move horizontally together. Since the two blocking rod frames 18 limit the two sides of the placement rod 13, and the two limiting rods 17 limit the two sides of the waterproof roll material, the protective film on the placement rod 13 and the waterproof roll material can always be kept in an aligned state, and the protective film is not easily distorted.
