Description

Technical Field

[0001] This application relates to the technical field of waterproof backing board production, and in particular to a waterproof backing board production equipment and process. Background Technology

[0002] Waterproof backing boards are building materials primarily used to enhance the waterproofing performance of walls, floors, or other structures. They are typically installed by applying a waterproofing material to the back side of the structure, the side most likely to be exposed to water pressure. Waterproof backing boards are commonly made from various materials such as polymer-modified cement board, PVC board, waterproof membrane, and fiberglass-reinforced cement board, offering good waterproofing, moisture resistance, pressure resistance, and crack resistance.

[0003] For example, patent application CN119159663A discloses a fully automated production process and equipment for waterproof backing boards. By employing rapid hot air drying, the production efficiency of waterproof backing boards is significantly improved. Simultaneously, by cleverly utilizing the seamless arrangement of extruded polystyrene boards, the entire production process requires only one cutting step, avoiding warping of the waterproof backing boards caused by shrinkage stress resulting from natural or steam curing. This effectively reduces waste generation, reducing scrap waste by at least half compared to the original production method. This process not only effectively reduces labor and space requirements but also increases production capacity while ensuring product quality.

[0004] The method of preparing waterproof backing boards by spraying cement slurry and drying, or by adhering the waterproof membrane to a PVC board, although belonging to the field of waterproof backing board production, and utilizing the above-mentioned existing technology to dry the waterproof membrane adhered to the PVC board and make the waterproof membrane adhere to the PVC board, still has some defects in practical applications: the above-mentioned patent application only uses hot air to dry and fix the waterproof membrane, which is a relatively simple method. The drying deformation of the waterproof membrane after drying generates different stresses, causing the waterproof membrane to easily bulge and deform, affecting the adhesion and fixation effect of the waterproof membrane on the PVC board. Summary of the Invention

[0006] The drying mechanism includes: A drying board, mounted on a horizontal base plate by a support rod, is used to dry boards with an adhered waterproof membrane.

[0007] The pressing rollers are symmetrically arranged along the length of the horizontal base plate.

The horizontal base plate is equipped with a control component for controlling the active rotation of the pressing rollers.

[0008] The pressing assembly is located between two pressing rollers and is used to reciprocate pressing the adhered waterproof membrane along the width direction of the horizontal base plate.

[0009] Preferably, the mounting mechanism includes: The support frame consists of two parts, which are symmetrically distributed along the width of the horizontal base plate and installed on the horizontal base plate.

[0010] The winding roller, positioned between two support frames and mounted on the two support frames via bearings, is used to wind a waterproof membrane.

[0011] The guide roller, located between the two support frames and mounted on the two support frames via bearings, is used to reverse the direction of the waterproof membrane and attach it to the board.

[0012] Preferably, the horizontal base plate is symmetrically provided with movable frames along its length direction, and the movable frames slide back and forth along the length direction of the horizontal base plate. A fixed plate is symmetrically provided between the two movable frames along the width direction of the horizontal base plate, and the two ends of the fixed plate are installed on the movable frames on the corresponding sides. The pressing roller is installed on the movable frame through bearings, and the shaft head of the pressing roller passes through the movable frame on the corresponding side.

[0013] Preferably, the control component includes: The support base is symmetrically arranged along the width of the horizontal base plate and installed on the horizontal base plate. The support base has an adjustment groove, and a linkage rod corresponding to the pressing roller is slidably arranged inside the adjustment groove.

[0014] The sliding rod is limited and slidably set on the head of the pressing roller and reciprocates along the length of the pressing roller. The end of the sliding rod away from the corresponding pressing roller is installed on the corresponding linkage rod.

[0015] The elastic telescopic rod is installed on the side of the linkage rod near the corresponding pressing roller, and the telescopic end of the elastic telescopic rod is installed on the fixed plate on the corresponding side.

[0016] Preferably, the adjustment groove is a U-shaped structure, and the inner wall of the end of the adjustment groove away from the support frame is set as a raised structure, and the raised structure is a smooth inclined surface, and the inner wall of the adjustment groove near the support frame is set as an inclined structure.

[0017] Preferably, the horizontal base plate is symmetrically provided with a rack plate along its width direction, and the rack plate is mounted on the horizontal base plate by a support protrusion, and a gear is mounted on the sliding rod that meshes with the rack plate.

[0018] Preferably, the pressing assembly includes: The support links are mounted on the fixed plate, and a reciprocating rod is slidably mounted on both support links.

[0019] Multiple connecting rods are evenly arranged along the length of the reciprocating rod and installed at the bottom of the reciprocating rod.

[0020] Multiple pressing plates are provided, each corresponding to a connecting rod. They are installed at the bottom of the connecting rod and move back and forth along the width of the horizontal base plate.

[0021] The ball bearings are evenly distributed at the bottom of the pressing plate.

[0022] Preferably, a horizontal rod is installed on the horizontal base plate via a vertical protrusion, and multiple adjusting blocks are evenly installed on the horizontal rod along its length. An adjusting round block that cooperates with the adjusting blocks is installed on the reciprocating rod, and a telescopic elastic rod is installed on the support connecting rod near the adjusting round block. A fixed protrusion is installed at the telescopic end of the telescopic elastic rod, and the fixed protrusion is installed on the reciprocating rod.

[0023] Preferably, a rubber sleeve is provided on the circumferential surface of the pressing roller, and the height of the rubber sleeve is lower than the height of the guide roller.

[0024] Secondly, a waterproof backing board manufacturing process includes the following steps: S1: Placement preparation, placing the board inside the sliding groove and making the end of the board near the support frame adhere to the waterproof membrane.

[0025] S2: Lamination process, moving the board, at this time the waterproof membrane is attached to the board by the guide roller.

[0026] S3: Flattening and drying. The waterproof membrane is flattened and pressed by the pressing rollers and pressing components, and finally dried by the drying plate.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. In the drying mechanism designed in this invention, the pressing roller and the pressing assembly cooperate with each other to press the waterproof membrane during the drying process, which can balance the stress generated by the deformation of the waterproof membrane during the drying process, thereby avoiding the possibility of bulging and deformation of the waterproof membrane during the drying process.

[0028] 2. The pressing roller designed in this invention applies uniform longitudinal pressure to the waterproof membrane, which can effectively counteract the tensile stress of the board along the length of the horizontal base plate, i.e., the processing direction. This reduces local deformation of the waterproof membrane caused by stress concentration, ensuring that the waterproof membrane remains flat after drying. In the pressing assembly, the pressing plate and the ball bearings form a dynamic compensation system. The reciprocating oscillation of the pressing plate can balance the uneven shrinkage force of the waterproof membrane in the width direction of the horizontal base plate. This multi-directional adjustment mechanism can avoid the internal stress difference caused by the anisotropy of the board. The combination of the above two methods significantly and further reduces the risk of bulging caused by uneven stress release during the drying process.

[0029] 3. In the control component designed in this invention, the pressing roller can actively rotate to press the waterproof membrane on the board when it moves in the board processing direction. The active rotation of the pressing roller can reduce the sliding friction between it and the waterproof membrane, and avoid local stress concentration or tensile deformation caused by speed difference. When the pressing roller moves away from the board processing direction, the control component makes the pressing roller stop rotating actively, that is, eliminates the risk of the waterproof membrane rewinding due to reverse rotation, and avoids wrinkles in the waterproof membrane caused by the reverse rotation of the pressing roller.

[0044] The following combination Figures 1 to 13 This application will be described in further detail.

[0045] This application discloses a waterproof backing board production equipment and process. By actively pressing the board in the forward direction, the stress generated by the deformation of the waterproof membrane during the drying process can be balanced, thereby avoiding the possibility of bulging and deformation of the waterproof membrane during the drying process.

[0046] Example 1:

[0047] See Figure 1 as well as Figure 2 A waterproof backing board production equipment includes a horizontal base plate 1, a sliding groove for placing boards is provided on the horizontal base plate 1, an installation mechanism 2 for adhering a waterproof membrane to the boards and a drying mechanism 3 for drying the waterproof membrane are installed on the horizontal base plate 1.

[0048] Installation mechanism 2 includes: There are two support frames 21, which are symmetrically distributed along the width of the horizontal base plate 1 and installed on the horizontal base plate 1.

[0049] The winding roller 22 is disposed between the two support frames 21 and mounted on the two support frames 21 via bearings, and is used to wind the waterproof membrane.

[0050] Guide roller 23 is set between two support frames 21 and mounted on the two support frames 21 through bearings. It is used to change the direction of the waterproof membrane and attach the waterproof membrane to the board.

[0051] In practice, the board is placed inside the sliding groove, the waterproof membrane wound on the winding roller 22 is pulled and passed through the guide roller 23 to contact the top of the board. The guide roller 23 can guide and press the waterproof membrane passing through its circumference, so that the waterproof membrane adheres to the board. Then the board is pushed to move it towards the drying mechanism 3. When the waterproof membrane completely covers the board, the waterproof membrane is separated by existing cutting tools, etc. Repeating the above actions can cover the board with a waterproof membrane.

[0052] See Figure 2 as well as Figure 3 The drying mechanism 3 includes a drying plate 31, which is mounted on a horizontal base plate 1 via a support rod, and is used to dry the plates with the waterproof membrane adhered to them.

[0053] The pressing roller 32 is symmetrically arranged along the length of the horizontal base plate 1 and is used to press the adhered waterproof membrane along the length of the horizontal base plate 1. The horizontal base plate 1 is provided with a control component 33 for controlling the active rotation of the pressing roller 32.

[0054] The pressing assembly 34 is disposed between the two pressing rollers 32 and is used to reciprocate pressing the adhered waterproof membrane along the width direction of the horizontal base plate 1.

[0055] During the drying process of the waterproof membrane, the pressing roller 32 and the pressing assembly 34 work together to press the waterproof membrane, which can balance the stress generated by the deformation of the waterproof membrane during the drying process, thereby avoiding the possibility of bulging and deformation of the waterproof membrane during the drying process.

[0056] See Figure 3 A movable frame 11 is symmetrically arranged on the horizontal base plate 1 along its length direction, and the movable frame 11 slides back and forth along the length direction of the horizontal base plate 1. A fixed plate 12 is symmetrically arranged between the two movable frames 11 along the width direction of the horizontal base plate 1, and the two ends of the fixed plate 12 are installed on the movable frame 11 on the corresponding side. The pressing roller 32 is installed on the movable frame 11 through the bearing, and the shaft head of the pressing roller 32 passes through the movable frame 11 on the corresponding side.

[0057] The drying plate 31 has a resistance wire at its bottom. When energized, the resistance wire heats up, drying the coated board. In operation, the coated board enters the bottom of the drying plate 31 via a sliding groove. An external drive cylinder drives the moving frame 11 to reciprocate along the length of the horizontal base plate 1. During this reciprocating movement, the moving frame 11, via the fixed plate 12, drives the pressing roller 32 to press the coated board. The pressing roller 32 applies uniform longitudinal pressure to the waterproof membrane, effectively counteracting the pressure along the length of the horizontal base plate 1 (i.e., the processing direction). Figure 1 The tensile stress (arrow) can reduce local deformation of the waterproof membrane caused by stress concentration, thus ensuring that the waterproof membrane remains flat after drying.

[0058] Continue reading Figure 3 A rubber sleeve 321 is provided on the circumference of the pressing roller 32. The rubber sleeve 321 is made of high-temperature resistant material to ensure that the rubber sleeve 321 will not melt when the drying plate 31 heats the plate. The height of the rubber sleeve 321 is lower than that of the guide roller 23, so that the guide roller 23 contacts the plate first to complete the initial positioning of the waterproof membrane. Then, the pressing roller 32 applies greater pressing pressure through the compression deformation of the rubber sleeve 321. This stepped contact design can prevent the waterproof membrane from being fully pressed prematurely. At the same time, when the rubber sleeve 321 is squeezed and deformed with the plate, it can increase the external force of the pressing roller 32 on the waterproof membrane, ensuring the pressing effect of the pressing roller 32 on the waterproof membrane.

[0059] See Figure 4 as well as Figure 5 In order to ensure the pressing effect of the pressing roller 32, the gear 14 and the rack plate 13 provided by the present invention can cooperate with each other to drive the drive roller to rotate actively. Specifically, the horizontal base plate 1 is symmetrically provided with rack plate 13 along its width direction, and rack plate 13 is mounted on the horizontal base plate 1 through a support protrusion. The sliding rod 334 is equipped with gear 14 that meshes with rack plate 13.

[0060] In actual operation, the pressing roller 32 rotates through the meshing transmission between the gear 14 and the rack 13 during its reciprocating movement. As the pressing roller 32 moves in the direction of the sheet material processing, it can actively rotate to press the waterproof membrane on the sheet material. The active rotation of the pressing roller 32 can reduce the sliding friction between it and the waterproof membrane. At the same time, the active rotation of the pressing roller 32 can apply an external force to the waterproof membrane, further stretching the waterproof membrane adhering to the sheet material, thus avoiding local stress concentration or tensile deformation caused by speed difference.

[0061] See Figures 4 to 6 The control component 33 includes: The support base 331 is symmetrically arranged along the width direction of the horizontal base plate 1 and installed on the horizontal base plate 1. The support base 331 has an adjustment groove 332, and a linkage rod 333 corresponding to the pressing roller 32 is slidably arranged inside the adjustment groove 332.

[0062] The sliding rod 334 is slidably set on the shaft of the pressing roller 32 and reciprocates along the length of the pressing roller 32. The end of the sliding rod 334 away from the corresponding pressing roller 32 is installed on the corresponding linkage rod 333.

[0063] The elastic telescopic rod 335 is installed on the side of the linkage rod 333 near the corresponding pressing roller 32, and the telescopic end of the elastic telescopic rod 335 is installed on the fixed plate 12 on the corresponding side.

[0064] The adjusting groove 332 has a U-shaped structure, and the inner wall of the adjusting groove 332 away from the support frame 21 is set as a raised structure, and the raised structure is a smooth inclined surface. The inner wall of the adjusting groove 332 near the support frame 21 is set as an inclined structure.

[0065] In the initial state, the elastic telescopic rod 335 is in a compressed state, that is, the gear 14 and the rack plate 13 are meshed with each other, and the sliding rod 334 can only slide back and forth along the length direction of the pressing roller 32. In specific operation, when the moving frame 11 drives the pressing roller 32 to move along the plate processing direction through the fixed plate 12, the gear 14 and the rack plate 13 mesh with each other to drive the pressing roller 32 to rotate actively. The actively rotating pressing roller 32 can actively press the plate. At this time, the linkage rod 333 slides inside the adjusting groove 332.

[0066] The raised structure consists of two inclined surfaces. Specifically, when the linkage rod 333 moves to the raised structure, it moves along the inclined surface close to the horizontal base plate 1. At this time, the elastic telescopic rod 335 resets synchronously. As the elastic telescopic rod 335 resets, when the linkage rod 333 crosses the junction of the raised structure, the elastic telescopic rod 335 is in a non-working state, that is, the elastic telescopic rod 335 neither stretches nor contracts. The pressing roller 32 no longer moves. At this time, the sliding rod 334 moves away from the horizontal base plate 1 and drives the gear 14 to disengage from the rack plate 13. The pressing roller 32 resets. During the reset process, the pressing roller 32 no longer rotates actively through the meshing of the gear 14 and the rack plate 13.

[0067] During the reset process of the pressing roller 32, the linkage rod 333 is simultaneously driven to slide along the inclined surface away from the horizontal base plate 1. At this time, the linkage rod 333 drives the sliding rod 334 to move synchronously to the side away from the horizontal base plate 1, and the elastic telescopic rod 335 is stretched. After the linkage rod 333 moves out of the protruding structure, it continues to move along the adjusting groove 332. When the linkage rod 333 moves to the inclined structure, due to the elastic potential energy of the elastic telescopic rod 335, the elastic telescopic rod 335 drives the linkage rod 333 to move to the side closer to the horizontal base plate 1, thereby driving the linkage rod 333 to move to the inclined structure. When the pressing roller 32 moves again along the plate processing direction, it can drive the linkage rod 333 to move along the inclined structure. Then, the sliding rod 334 is driven by the linkage rod 333 to reset again, that is, the sliding rod 334 drives the gear 14 to mesh with the rack plate 13.

[0068] It should be noted that the inclined surface at the protruding structure, away from the horizontal base plate 1, can provide driving force for the sliding rod 334 to return to the inclined structure through the cooperation of the linkage rod 333 and the elastic telescopic rod 335.

[0069] Thus, when the pressing roller 32 moves in the direction of board processing, it can actively rotate to press the waterproof membrane on the board. The active rotation of the pressing roller 32 can reduce the sliding friction between it and the waterproof membrane, and avoid local stress concentration or tensile deformation caused by speed difference. When the pressing roller 32 moves away from the direction of board processing, the control component 33 makes the pressing roller 32 stop rotating actively, that is, eliminate the risk of the waterproof membrane rewinding due to reverse rotation, and avoid wrinkles in the waterproof membrane caused by the reverse rotation of the pressing roller 32.

[0070] The teeth on gear 14 and rack plate 13 are thin enough to ensure normal transmission, thus ensuring that gear 14 can smoothly mesh with rack plate 13 when it is reset.

[0071] See Figures 7 to 9 The pressing assembly 34 includes: Support rod 341 is mounted on fixed plate 12, and reciprocating rod 342 is slidably mounted on both support rods 341.

[0072] Multiple connecting rods 343 are evenly arranged along the length of the reciprocating rod 342 and installed at the bottom of the reciprocating rod 342.

[0073] Multiple pressing plates 344 are provided, each corresponding to a connecting rod 343. They are installed at the bottom of the connecting rod 343 and move back and forth along the width direction of the horizontal base plate 1.

[0074] Ball bearings 345 are evenly distributed at the bottom of the pressing plate 344.

[0075] In actual operation, the reciprocating rod 342 is driven to move back and forth along the width direction of the horizontal base plate 1 by an external drive cylinder. During the reciprocating movement of the reciprocating rod 342 on the support connecting rod 341, the pressing plate 344 is driven to move back and forth through the connecting rod 343. During the reciprocating movement of the pressing plate 344, it forms a dynamic compensation system with the ball bearing 345. The reciprocating swing of the pressing plate 344 can balance the uneven shrinkage force of the waterproof membrane in the width direction of the horizontal base plate 1. This multi-directional adjustment mechanism can avoid the internal stress difference caused by the anisotropy of the board.

[0076] The ball bearing 345 can change the sliding friction between the pressing plate 344 and the sheet material into rolling friction, thereby reducing the wear of the pressing plate 344 on the sheet material.

[0077] See Figure 8 The adjustment block 16 and the adjustment round block 17 provided by the present invention cooperate with each other to drive the reciprocating rod 342 to move back and forth along the width direction of the horizontal base plate 1. Specifically, a horizontal rod 15 is installed on the horizontal base plate 1 through a vertical protrusion. Multiple adjustment blocks 16 are evenly installed on the horizontal rod 15 along its length direction. An adjustment round block 17 that cooperates with the adjustment block 16 is installed on the reciprocating rod 342. A telescopic elastic rod 18 is installed on the support connecting rod 341 near the adjustment round block 17. A fixed protrusion is installed on the telescopic end of the telescopic elastic rod 18, and the fixed protrusion is installed on the reciprocating rod 342.

[0078] The adjusting block 16 has a triangular structure, and the top of the adjusting block 16 away from the horizontal base plate 1 has an arc-shaped structure, which facilitates the adjusting block 17 to successfully pass over the top of the adjusting block 16 away from the horizontal base plate 1. In specific operation, the moving frame 11 drives the reciprocating rod 342 to move back and forth along the length direction of the horizontal base plate 1 through the fixed plate 12 and the supporting connecting rod 341. During this process, the adjusting block 17 contacts the side of the adjusting block 16 and moves along the side of the adjusting block 16. The pressing plate 344 moves away from the horizontal base plate 1. When the adjusting block 17 passes the top of the adjusting block 16, the telescopic elastic rod 18 resets and drives the reciprocating rod 342 to reset towards the horizontal base plate 1. The adjusting block 16, through the cooperation of the horizontal rod 15 and the adjusting block 17, can drive the reciprocating rod 342 to move back and forth along the width direction of the horizontal base plate 1. The telescopic elastic rod 18 and the fixed protrusion cooperate to reset the reciprocating rod 342.

[0079] After the above steps are completed, a waterproof backing board is obtained.

[0080] Example 2: Refer to Figures 10 to 12Based on Embodiment 1, a horizontal frame 121 is installed between the fixed plates 12. Multiple rotating shafts 122 are evenly arranged along the length of the horizontal frame 121. The rotating shafts 122 are rotatably mounted on the horizontal frame 121 through bearings. A rotating disk 123 is installed at the bottom of the rotating shaft 122. A ball 124 is installed at the bottom of the rotating disk 123. A sprocket is installed on the rotating shaft 122. A gear 125 is installed on any rotating shaft 122. A rack plate 126 that meshes with the gear 125 is installed on the horizontal base plate 1 through a fixed connecting rod.

[0081] A chain (not shown in the figure) is installed between the sprockets. In operation, the moving frame 11 drives the fixed frame to move back and forth along the length of the horizontal base plate 1, which in turn drives the horizontal frame 121 to move. During the movement of the horizontal frame 121, the rotating shaft 122 moves. During the movement of the rotating shaft 122, which is equipped with gear 2 125, it meshes with the rack plate 2 126 and rotates. During the rotation of the rotating shaft 122, which is equipped with gear 2 125, the remaining rotating shaft 122 is driven to rotate through the sprocket and chain transmission. During the rotation of the rotating shaft 122, the rotating disk 123 is driven to rotate. During the rotation of the rotating disk 123, a circumferential rotational force can be applied to the waterproof membrane on the board, so that the force on the waterproof membrane is more uniform and the surface of the waterproof membrane is more intact after drying.

[0082] The rotating disks 123 fit together perfectly, meaning that there are no gaps or collisions during the rotation of the rotating disks 123.

[0083] Finally, see Figure 13 The present invention also provides a manufacturing process for a waterproof backing board, the process comprising the following steps: S1: Placement preparation: Place the board inside the sliding groove and make the end of the board near the support frame 21 adhere to the waterproof membrane.

[0084] S2: Lamination process, moving the board, at this time the waterproof membrane is attached to the board by the guide roller 23.

[0085] S3: Flattening and drying. The coated sheet enters the bottom of the drying plate 31 through the sliding groove. At this time, the moving frame 11 is driven by an external driving cylinder to move back and forth along the length of the horizontal base plate 1. During the reciprocating movement of the moving frame 11, the pressing roller 32 is driven by the fixed plate 12 to press the coated sheet. The reciprocating rod 342 is driven by an external driving cylinder to move back and forth along the width of the horizontal base plate 1. During the reciprocating movement of the reciprocating rod 342 on the support connecting rod 341, the pressing plate 344 is driven to move back and forth through the connecting rod 343. During the reciprocating movement of the pressing plate 344, it forms a dynamic compensation system with the ball bearing 345. The reciprocating swing of the pressing plate 344 can balance the uneven shrinkage force of the waterproof membrane in the width direction of the horizontal base plate 1. Finally, the waterproof membrane is dried by the drying plate 31.
