Description

Technical Field

[0001] The invention relates to the technical field of waterproof coiled material production, and in particular to a production line and process for a three-layer self-adhesive waterproof coiled material. Background Art

[0002] The tensile strength and elongation of traditional wet-laid waterproof membranes cannot be balanced, and leakage is prone to occur in shear walls, deformation joints and other parts due to structural settlement and deformation. We have designed a three-layer carcass structure wet-laid waterproof membrane - TPZ molecular adhesive polymer series waterproof membrane (three-carcass base type); it has the following advantages: 1. Improve the physical properties of existing wet-laid waterproof membranes, such as maximum tensile force, maximum tensile elongation, and impermeability; 2. Add a layer of polyethylene tire on the basis of a layer of high-strength resin tire to provide a large elongation, and then a layer of polyester fiber tire body to improve the tensile strength. Even if the high-strength resin tire and the polyester fiber tire body are broken, the second layer can still achieve the purpose of double insurance; 3. Optimize the asphalt colloid of the coiled material to make it soft and easy to construct; 4. From the perspective of roll material construction methods, simplify the construction process and improve construction efficiency.

[0003] Therefore, three-ply self-adhesive waterproof membrane is widely used. During production, the three-ply self-adhesive waterproof membrane needs to be rolled through four sets of rolling structures. During rolling, an adhesive needs to be set between the two layers of substrate that are rolled and bonded. The adhesive is discharged through the glue coating bin and then rolled by a pair of rollers, so that the adhesive is coated between the two layers of substrate. In the actual production process, the thickness of the membrane can be controlled by adjusting the gap between the pairs of rollers. Therefore, the gap between the pairs of rollers needs to be adjusted frequently. When adjusting the gap between the pairs of rollers, since the glue coating bin is currently fixed, the glue coating bin cannot be adjusted accordingly when adjusting the gap between the pairs of rollers, resulting in the glue outlet of the glue coating bin being unable to move accordingly. The gap between the pairs of rollers at the glue outlet will be staggered, which will affect the gluing effect and thus affect the quality of the gluing.

[0004] When applying glue, in order to prevent the adhesive from flowing out on both sides of the coil, glue baffles are set at both ends of the rollers. Currently, the glue baffles are fixed on the frame. When adjusting the gap between the rollers, the position of the glue baffles also needs to be adjusted manually. Since the space where the glue baffles are set is small, the adjustment is inconvenient. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems and provide a three-layer self-adhesive waterproof membrane production line and process.

The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

[0035] Please refer to Figure 1-5 As a specific implementation, the technical solution of the present invention is: a three-layer self-adhesive waterproof membrane production line, including a plurality of roller pressing structures arranged at intervals, the roller pressing structure includes: The roller assembly 2 comprises a first beam 22 and a first roller 20 and a second roller 21 which are arranged parallel and spaced on the first beam 22, wherein the first roller 20 is rotatably connected to the first beam 22, and the second roller 21 is guided and slidably matched with the first beam 22; The centering assembly 5 comprises a second beam 3, a vertically arranged guide sleeve 543, and two first arms 54 symmetrically arranged on both sides of the guide sleeve 543 and hingedly connected to the guide sleeve 543, the other end of one first arm 54 is rotatably connected to the second beam 3, the other end of the other first arm 54 is guided and slidably matched with the second beam 3, and a second guide rod 57 is guided in the guide sleeve 543; The glue coating chamber 1 is connected to the second guide rod 57 .

The specific structures of the third rolling structure 93 and the fourth rolling structure 94 are consistent with the second roller 21 pressing structure. When working, the PE film and the PET carcass in the first rolling structure 91 pass through the roller assembly, and the glue coating bin 1 applies glue between the PE film and the PET carcass. The thickness of the glue between the PE film and the PET carcass can be controlled by controlling the gap between the roller assembly 2. After gluing, the carcass passes through the water cooling groove (not shown in the figure) under the roller assembly to cool the carcass. Figure 1 A wind knife assembly 4 is provided between two adjacent rolling structures. The wind knife assembly 4 blows air to dry the carcass. The carcass cooled by the water cooling trough enters the second rolling structure 91 after passing through the wind knife assembly 4. The carcass dried by the wind knife is wound on the roller assembly 2 of the second rolling structure 92. The second turning frame 101 in the second roller 21 pressing structure provides a PET carcass, which is wound on the roller assembly 2. The glue coating bin 1 above the roller assembly 2 is coated with glue, so that the PET carcass is pasted on the carcass that has passed through the first rolling structure 91. Then, it passes through the water cooling trough and the wind knife assembly 4, enters the third rolling structure 93 and the fourth rolling structure 94, and the PET carcass is pasted layer by layer, so as to form a three-layer PET carcass, a three-layer adhesive layer and a layer of PE film.

[0042] Further, as a specific implementation method, refer to Figure 6A first sliding member 210 is provided on the first beam 22 for guiding sliding.

[0046] Embodiment 3 refer to Fig.10The present application provides a three-base self-adhesive waterproof membrane production line. It can be understood that when the position of the glue bin 1 is adjusted by guiding the second guide rod 57 only by the cooperation of the first arm 54 and the guide sleeve 543, the stability is not good. When the lower end of the second guide rod 57 is suspended too long, the vibration of the equipment will cause the glue bin 1 to vibrate with a large amplitude, which is not conducive to the uniformity of glue coating. Based on this problem, as a further improvement, the centering component 5 also includes a horizontally arranged rigid plate 562, both ends of the rigid plate 562 are hingedly connected to the second arms 561, and the other ends of the two second arms 561 are rotatably connected to the two support shafts 51 respectively, and the rigid plate 562 is provided with a second guide channel 5623 that cooperates with the second guide rod 57.

[0047] Specifically, refer to Figure 8-Figure 11 , the two ends of the rigid plate 562 are hingedly connected with the second arm 561 through the second axis 563, the second axis 563 is arranged parallel to the first axis 541, and the other end of the second arm 561 is provided with a second connecting sleeve 560, and the second connecting sleeves 560 of the two second arms 561 are respectively rotatably matched with the ends of the two connecting shafts, and a second guide channel 5623 corresponding to the second guide rod 57 is provided on the rigid plate 562, and the second guide rod 57 is guided and matched with the second guide channel 5623, and the ends of the two first arms 54 away from the support shaft 51 are arranged upwardly tilted, and the ends of the two second arms 561 are arranged downwardly tilted, and the second arm 561 is located on the side of the first arm 54 away from the second beam 3.

The second guide rod 57 is limited in the vertical direction by the limit of the strip hole 581 and the plug-in plate 591 and the elastic force balance of the first compression spring 570. When the centering component 5 is adjusted for horizontal displacement, the first compression spring 570 continues to provide elastic force, and at the same time, through the limit cooperation of the plug-in plate 591 and the strip hole 581, it is ensured that the second guide rod 57 does not move in the axial direction, and the glue coating bin 1 and the glue baffle plate 25 do not move in the vertical direction, thereby ensuring the stability of glue coating and glue baffle.

[0054] As a preferred embodiment, a first limit plate 567 is provided at the upper end of the first guide rod 565, which is located between the first limit plate 567 and the rigid plate 562. A second compression spring 566 is also sleeved on the outer periphery of the first guide rod 565. The second compression spring 566 can provide an upward elastic force for the first guide rod 565. Through this arrangement, when the second sliding member 533 is adjusted in the direction away from the second bearing seat 52, the guide sleeve 543 will be displaced vertically downward, and the rigid plate 562 can be displaced upward, then the compression amount of the second compression spring 566 will increase, and the compression amount of the first compression spring 570 will decrease. At this time, the increased elastic force of the second compression spring 566 can compensate for the reduced elastic force of the first compression spring 570, thereby ensuring that the total elastic force provided by the first compression spring 570 and the second compression spring 566 to the second connecting plate 564 is maintained in a relatively balanced range; on the contrary, when the second sliding member 533 is adjusted in the direction close to the second bearing seat 52, the guide sleeve 54 3 will be displaced vertically upward, while the rigid plate 562 can be displaced downward, then the compression amount of the second compression spring 566 will be reduced, and the compression amount of the first compression spring 570 will increase. At this time, the increased elastic force of the first compression spring 570 can compensate for the reduced elastic force of the second compression spring 566, thereby ensuring that the total elastic force provided by the first compression spring 570 and the second compression spring 566 to the second connecting plate 564 is maintained in a relatively balanced range; thereby, when the centering component 5 is adjusted, the upward elastic force of the second connecting plate 564 can be maintained in a relatively stable range, avoiding the phenomenon that the glue coating bin 1 moves in the vertical direction due to the reduction of the upward elastic force provided to the second connecting plate 564, thereby ensuring the stability of the adjustment; and in this way, when the centering component 5 is adjusted, the elastic forces of the first compression spring 570 and the second compression spring 566 can change in opposite directions, so that the resistance encountered by the second sliding member 533 when it is adjusted in the horizontal direction is relatively stable, thereby improving the stability of the adjustment.

[0055] Embodiment 4 refer to Fig.13 , Fig.14 The present application provides a three-layer self-adhesive waterproof membrane production line, including a glue coating bin 1, the glue coating bin 1 includes a bin body, a glue outlet 12 is arranged at the lower end of the bin body, a glue inlet pipe 120 is arranged at the top, and third linear drive members 11 are arranged on the upper surfaces of both ends of the bin body, the lower end of the third linear drive member 11 is connected to a sleeve body, and two scrapers 13 are connected to the two sides of the sleeve body through a hinge shaft, and a torsion spring is arranged between the scraper 13 and the sleeve body. Under the elastic force of the torsion spring, the lower ends of the two scrapers 13 can be deflected in a direction away from each other, so that the lower ends of the two scrapers 13 are in contact with the side wall of the bin body, and when the third linear drive member 11 drives the two scrapers 13 to move up and down, the inner wall of the bin body can be scraped by the lower end of the scraper 13.

[0056] refer to Fig.14The specific structure of the third linear drive member 11 includes a heat-conducting tube arranged on the warehouse body and thermally coupled with the warehouse body, a rigid rod 110 guided and arranged on the upper side wall of the warehouse body, a breathable plate 112 arranged on the upper end of the rigid rod 110, and an annular piston 111 that cooperates with the outer circumference of the rigid rod 110 and the inner circumference of the heat-conducting tube in a guiding sliding seal; below the piston 111, a thermal expansion liquid is arranged in the heat-conducting tube, a third compression spring 115 is arranged between the breathable plate 112 and the upper end of the heat-conducting tube, and a detection sensor 114 and a limiter 113 are arranged on the side wall of the heat-conducting tube, refer to Fig.11 A pressure sensor 5621 is provided on the upper surface of the rigid rod 110 around the first guide channel 5620. The pressure sensor 5621 is connected to the detection sensor 114 and the limiter 113. The detection sensor 114 is a temperature sensor and the limiter 113 is an electric push rod.

[0057] When producing waterproof coiled materials, asphalt adhesive is provided to the glue coating chamber 1 through the glue inlet pipe 120. The asphalt adhesive has a certain temperature. After the heat is transferred to the heat-conducting cylinder, the heat expansion liquid is heated and expanded. After the expansion, the piston 111 is pushed upward, and the air-permeable plate 112 is driven to move upward to squeeze the third compression spring 115. Since the temperature range of the asphalt adhesive is constant, when the temperature of the heat expansion liquid is close to the temperature of the asphalt adhesive, the temperature no longer rises, the volume no longer expands, and the asphalt adhesive is in a state of being ... Fig.14 In the state shown, when the temperature sensor detects that the temperature reaches a predetermined value, the limit member 113 is triggered to be pushed out. The limit member 113 adopts an electric push rod, and a friction plate is provided at the end of the electric push rod. After the electric push rod is pushed out, the friction plate contacts and frictionally cooperates with the side wall of the air permeable plate 112 to limit the air permeable plate 112.

[0058] When producing waterproof membrane, the state of the centering component 5 is as follows Figure 8As shown, at this time, one end of the first elastic member is in contact with the first limiting plate 567, and the other end is in contact with the upper surface of the pressure sensor 5621. The elastic force of the first compression spring 570 can be detected by the pressure sensor 5621. During the production of the waterproof coiled material, the amount of compression of the first compression spring 570 is within a constant range. At this time, the electric push rod keeps pushing out the state of limiting the breathable plate 112. When the waterproof coiled material production line is about to be completed, the glue supply will be stopped according to the length of the remaining coiled material. The adhesive in the glue coating bin 1 will flow down under the action of gravity to ensure that there is little adhesive remaining in the glue coating bin 1 after the production is completed. After the production is completed, the glue supply is stopped, the temperature in the glue coating bin 1 is reduced, and a certain amount of asphalt adhesive will remain on the side wall of the glue coating bin 1. At this time, the temperature of the thermal expansion liquid decreases and contracts, so the piston 111 moves downward. At this time, since the breathable plate 112 is limited, the breathable plate 112 will not return to its position. At this time, the second linear drive member 53 and the first linear drive member 53 are controlled. The driving member 23 synchronously drives the second roller 21 to move away from the first roller 20, so that there is a sufficiently large gap between the first roller 20 and the second roller 21. During the adjustment process, the compression amount of the first compression spring 570 gradually becomes very high, and the elastic force increases. When the first roller 20 and the second roller 21 are adjusted to a suitable gap, the compression amount of the first compression spring 570 reaches a predetermined value, and the pressure value detected by the pressure sensor 5621 reaches the first predetermined value. When the pressure value detected by the pressure sensor 5621 reaches the first predetermined value, the limit member 113 contracts and releases the air permeable plate 112. At this time, the elastic force of the third compression spring 115 pushes the air permeable plate 112 to drive the rigid rod 110 to move downward, and pushes the scraper 13 to scrape and clean the inside of the glue coating chamber 1. The scraped adhesive flows out from the glue outlet 12. At this time, since the gap between the first roller 20 and the second roller 21 is sufficient, the downstream adhesive will not adhere to the first roller 20 and the second roller 21.

[0059] Specifically, refer to Fig.15 The scraper 13 is provided with connecting ends 131 at both ends, and the connecting ends 131 are provided with ear plates 132 hingedly connected to the rigid rod 110.

[0060] Embodiment 5 refer to Fig.16 ,This application also includes a three-layer self-adhesive waterproof membrane production process, including the following steps: Step 1: Adjust the working gap of the roller assembly 2; adjust the position of the second roller 21 according to the thickness of the waterproof coiled material, and adjust the gap between the first roller 20 and the second roller 21; Step 2: The centering assembly 5 is synchronously adjusted with the roller assembly 2, and the first arm 54 and one end of the guide slide of the second beam 3 are synchronously adjusted in the same direction with the second roller 21, driving the guide sleeve 543 and the glue coating bin 1 to synchronously adjust their displacement.

[0061] The specific working process of the present application is as follows: when adjusting the working gap between the first roller 20 and the second roller 21 according to the working conditions, the first sliding member 210 is driven to slide, driving the second roller 21 to move horizontally, and adjusting the size of the gap between the first roller 20 and the second roller 21. At the same time, the second sliding member 533 moves synchronously with the first sliding member 210 in the same direction, driving the first arm 54 to swing. During the first swing, the angle between the two first arms 54 changes, driving the guide sleeve 543 to move in the horizontal direction, thereby driving the glue coating bin 1 to move synchronously, and the moving displacement is equal to half of the adjustment displacement, thereby ensuring the gluing effect.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
