Technical Field
[0001] The invention relates to the technical field of asphalt waterproofing coiled material processing, in particular to asphalt waterproofing coiled material processing equipment and a processing method for building construction. Background Art
[0002] Asphalt waterproofing membrane is a roll material made of asphalt material, base material and anti-sticking material on the surface, often called asphalt felt. Asphalt waterproofing membrane can be divided into two types: base material and non-base material. Base material refers to the material made by impregnating base materials such as thick paper, glass cloth, asbestos cloth, cotton and linen fabrics with petroleum asphalt, while non-base material is made by adding asbestos, rubber powder, etc. to asphalt materials and rolling them.
[0003] The processing equipment of asphalt waterproofing membrane mainly includes raw material pretreatment, base cloth impregnation, coating thickness control, film exhaust, cooling and shaping, slitting and packaging, etc. Among them, film exhaust and cooling and shaping are crucial parts of the whole production process. Usually, the laminated film and modified asphalt layer are immersed in water or cooled by other cooling devices.
[0004] The Chinese patent discloses a "cooling device for waterproof coiled material" with application number 202221195383.9, which includes a frame and multiple water-cooled rollers. The water-cooled rollers are arranged in multiple layers, and each layer includes N water-cooled rollers arranged side by side in front and back and water supply mains and water collecting pipes on the left and right sides thereof; the water-cooled rollers include a rotating shaft, a cylinder and multiple support plates, and both ends of the rotating shaft are rotatably arranged on the frame; an annular sealing plate is provided on the inner wall of the left end of the cylinder, and its right end is a necking structure; there is an annular gap between the sealing plate and the rotating shaft, and the water supply main and the water collecting pipe are both arranged on the frame in the front-to-back direction, and N water supply branches are provided on the water supply main, and the inner ends of the water supply branches pass inwardly through the gap to between the sealing plate and the leftmost support plate; the right side of the necking structure forms an annular end face coaxial with the cylinder, and N notches are provided on the upper side of the water collecting pipe, and the lower part of the annular end face extends into the notch; the water of all the water collecting pipes is collected together; a plurality of hollow holes for water to flow through are provided on the support plate and around the rotating shaft.
[0005] Although the device can cool, due to the different shrinkage rates of the film and modified asphalt layer, their cooling and shrinkage speeds do not match, which can easily lead to peeling between the two. In addition, the edge of the film may be lifted, affecting its wrapping. During subsequent transportation and storage, the modified asphalt layer may be exposed and then contaminated or worn. Summary of the invention
[0006] The purpose of the present invention is to provide an asphalt waterproofing membrane processing device and a processing method for building construction. The present invention solves the problem that the existing equipment is prone to peeling and warping of the edge of the coating during the lamination and cooling process of the modified asphalt layer, thereby affecting the wrapping performance.
[0007] To achieve the above object, the present invention provides the following technical solution: an asphalt waterproofing coiled material processing device for construction, comprising a cooling box, and an extrusion roller located above the cooling box, and further comprising: The precooling mechanism includes a cooling roller connected to the cooling box, and a modified asphalt layer, a film coating and an extrusion roller are sequentially arranged above the cooling roller; the cooling roller and the extrusion roller work together to reduce the temperature gradient between the modified asphalt layer and the film coating while laminating the modified asphalt layer and the film coating through the precooling function of the cooling roller; The wrapping mechanism includes a plurality of water spray pipes connected to the cooling roller, and the two sides of the water spray pipes are bent downward at 45 degrees and surround the outside of the film in a ring; when the film shrinks, the widened reserved edges are tightly wrapped around the edge of the modified asphalt layer under the guidance of the spray water flow.
[0008] Preferably, the outer wall of the cooling box is connected to a water pump, one side of the water pump is connected to a second pipe, and the second pipe is connected to the cooling roller.
[0009] Preferably, fixed plates are symmetrically rotatably mounted at both ends of the cooling roller and the extrusion roller, and the fixed plates are fixedly mounted on the cooling box.
[0010] Preferably, spiral blades are installed inside the cooling roller.
[0011] Preferably, a support plate is fixedly mounted on the upper end surface of the water spray pipe, and both ends of the support plate are fixedly mounted on the cooling box.
[0012] Preferably, a plurality of water spray heads are installed on the side of the water spray pipe facing the coating.
[0013] Preferably, the upper end surface of the water spray pipe passes through the support plate and is connected to a third pipe, the third pipe is connected to the first pipe at a side away from the water spray pipe, and the first pipe is connected to the cooling roller at a side away from the third pipe.
[0014] Preferably, a first round rod and a second round rod are rotatably mounted on the inner wall of the cooling box.
[0015] Preferably, the method for processing asphalt waterproofing membrane for construction comprises the following steps: Step 1: When the film and modified asphalt layer are laminated by the squeeze roller and the cooling roller, the water in the cooling box enters the cooling roller. Since the cooling roller abuts against the modified asphalt layer, it will take away part of the heat of the modified asphalt layer, thereby reducing the temperature gradient between the film and modified asphalt layer; Step 2: As the film and modified asphalt layer move forward, the modified asphalt layer comes into contact with the water in the cooling box. At this time, the water spray pipe sprays water to cool the film on the modified asphalt layer. Since the water spray pipe is bent downward at 45 degrees and surrounds the outside of the film, the shrinkage of the film will cause the reserved edge to wrap around the outer wall of the modified asphalt layer.
[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is provided with a pre-cooling mechanism. When the cooling roller cooperates with the extrusion roller, the temperature gradient between the modified asphalt layer and the film is reduced by the pre-cooling function of the cooling roller while laminating the modified asphalt layer and the film.
[0017] 2. The present invention is provided with a wrapping mechanism. When the modified asphalt layer contacts the water in the cooling box, the water in the cooling roller enters the water spray pipe through the first pipe and the third pipe, and the water in the water spray pipe is sprayed out through the water spray head. At this time, the water spray head parallel to the coating cools it. The water spray heads at 45 degrees on both sides of the water spray pipe will make the reserved edge bend downward, and the reserved edge of the coating will not curl up, but will fit on the outer wall of the modified asphalt layer, thereby protecting the modified asphalt layer and preventing it from being contaminated or worn.

DETAILED DESCRIPTION
[0020] See also Figures 1 to 5 The present invention provides a technical solution: an asphalt waterproofing coiled material processing device for construction, comprising a cooling box 1, and an extrusion roller 5 located above the cooling box 1, and further comprising: The precooling mechanism includes a cooling roller 7 connected to the cooling box 1, and the modified asphalt layer 2, the coating film 3 and the squeeze roller 5 are arranged in sequence above the cooling roller 7; the cooling roller 7 cooperates with the squeeze roller 5 to reduce the temperature gradient between the modified asphalt layer 2 and the coating film 3 through the precooling function of the cooling roller 7 while laminating the modified asphalt layer 2 and the coating film 3; The wrapping mechanism includes a plurality of water spray pipes 14 connected to the cooling roller 7, and the two sides of the water spray pipes 14 are bent downward at 45 degrees and surround the outside of the coating 3 in a ring shape; when the coating 3 shrinks, its widened reserved edge 301 is tightly wrapped around the edge of the modified asphalt layer 2 under the guidance of the spray water flow.
[0021] Further, such as Figure 1 As shown, the outer wall of the cooling box 1 is connected to a water pump 9, one side of the water pump 9 is connected to a second pipe 8, and the second pipe 8 is connected to the cooling roller 7; when the water pump 9 is working, the water in the cooling box 1 will be transported to the cooling roller 7 through the second pipe 8.
[0022] Further, such as Figure 1 As shown, the cooling roller 7 and the squeezing roller 5 are symmetrically rotatably mounted with fixing plates 6 at both ends, and the fixing plates 6 are fixedly mounted on the cooling box 1 ; the fixing plates 6 support the squeezing roller 5 and the cooling roller 7 .
[0023] Further, such as Figure 5 As shown, a spiral blade 16 is installed inside the cooling roller 7; when the cooling roller 7 rotates, the spiral blade 16 is driven to rotate, so that the water flow through the cooling roller 7 is accelerated, so that the cooling roller 7 and the modified asphalt layer 2 can always maintain a large temperature difference and take away the heat in time.
[0024] Further, such as Figure 2 As shown, a support plate 11 is fixedly mounted on the upper end surface of the water spray pipe 14 , and both ends of the support plate 11 are fixedly mounted on the cooling box 1 ; the support plate 11 supports the water spray pipe 14 .
[0025] Further, such as Figure 3 As shown, a plurality of water spray heads 15 are installed on the side of the water spray pipe 14 facing the coating 3; the water spray heads 15 cool the coating 3 and bend the reserved edge 301 downward.
[0026] Further, such as Figure 1 As shown, the upper end surface of the water spray pipe 14 passes through the support plate 11 and is connected to a third pipe 12. The third pipe 12 is connected to the first pipe 4 on the side away from the water spray pipe 14. The first pipe 4 is connected to the cooling roller 7 on the side away from the third pipe 12. The water in the cooling roller 7 enters the water spray pipe 14 through the first pipe 4 and the third pipe 12.
[0027] Further, such as Figure 1 As shown, the inner wall of the cooling box 1 is rotatably mounted with a first round rod 10 and a second round rod 13 ; the first round rod 10 and the second round rod 13 change the movement tracks of the modified asphalt layer 2 and the coating 3 .
[0028] In this embodiment, Figure 4As shown, when the coating 3 passes through the water spray head 15, the reserved edge 301 will bend downward from the horizontal. At this time, the coating 3 shrinks, and the reserved edge 301 will wrap around the outer wall of the modified asphalt layer 2 without curling up.
[0029] In this embodiment, the method for processing asphalt waterproofing membrane for construction includes the following steps: Step 1: When the film 3 and the modified asphalt layer 2 are transported between the squeezing roller 5 and the cooling roller 7, the squeezing roller 5 and the cooling roller 7 laminate them. At the same time, the water pump 9 works to extract the water in the cooling box 1 through the second pipe 8 and enter the cooling roller 7. Since the cooling roller 7 is equipped with a spiral blade 16, the spiral blade 16 rotates with the cooling roller 7. The spiral blade 16 accelerates the flow of water, so that the modified asphalt layer 2 can be cooled better, thereby reducing the temperature gradient between the film 3 and the modified asphalt layer 2; Step 2: As the coating 3 and the modified asphalt layer 2 move forward, their paths will be changed by the first round rod 10. At this time, the modified asphalt layer 2 abuts against the water in the cooling box 1. At the same time, the water in the cooling roller 7 enters the water spray pipe 14 through the first pipe 4 and the third pipe 12. The water in the water spray pipe 14 is sprayed out through the water spray head 15. At this time, the water spray heads 15 parallel to the coating 3 cool it down. The water spray heads 15 arranged at 45 degrees on both sides of the water spray pipe 14 will make the reserved edge 301 bend downward. At this time, the coating 3 The film 3 and the modified asphalt layer 2 shrink when they are cooled. Since the water in the water spray pipe 14 flows in through the cooling roller 7, the temperature is different from the water temperature in the cooling box 1, so the difference in shrinkage speed between the film 3 and the modified asphalt layer 2 will be reduced. When the film 3 and the modified asphalt layer 2 pass through the second round rod 13, the lamination and cooling of the film 3 and the modified asphalt layer 2 are completed. The reserved edge 301 of the film 3 will not warp upward, but will fit on the outer wall of the modified asphalt layer 2, protecting the modified asphalt layer 2 from pollution or wear.
