Description

Technical Field

[0001] This invention relates to the field of tunnel waterproofing technology, specifically to a PVC waterproofing board and its preparation equipment and method. Background Technology

[0002] The current mainstream production process in the industry is the hot-melt calendering composite process: PVC sheets are heated and melted, then bonded to geotextile using rollers, and finally cooled to form a composite waterproof membrane. This process has many drawbacks in actual production. 1. High temperature can damage material properties: The high hot melt temperature can easily lead to the degradation, deformation and decline of mechanical properties of PVC sheets. At the same time, it can cause the geotextile fibers to become brittle and reduce their strength, affecting the long-term durability of the product.

[0003] 2. Unstable composite quality: Strict requirements for temperature, pressure and speed control can easily lead to problems such as insufficient local penetration, false adhesion, bubbles, and delamination. The bonding strength varies greatly, and there is a risk of delamination and leakage.

[0004] 3. High equipment and energy costs: It requires the configuration of heating, temperature control, high-pressure rolling and other systems, which involves large equipment investment and high energy consumption, making it difficult to control production costs.

[0005] At the same time, existing adhesive coating and laminating equipment generally uses integral anilox rollers for adhesive coating, which has revealed obvious shortcomings during use: 1. Anilox rollers are prone to clogging and difficult to clean: The adhesive tends to solidify and remain in the cells, which is difficult to remove completely with conventional solvent cleaning. Long-term use leads to insufficient adhesive application and uneven coating, affecting the quality of the composite.

[0006] 2. Maintenance requires machine shutdown and is inefficient: After blockage, the machine must be stopped to disassemble the entire roller, empty the glue box, and clean the glue path, which is time-consuming and labor-intensive and seriously affects continuous production efficiency.

[0007] 3. Waste of consumables and high environmental pressure: Cleaning the box requires discarding the remaining adhesive liquid, consuming a large amount of cleaning solvent, generating adhesive-containing waste liquid, increasing raw material loss and environmental treatment costs. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides a PVC waterproof board and its preparation equipment and method, solving the problems mentioned in the background section.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a PVC waterproof board, comprising a waterproof structure, wherein the waterproof structure is composed of a PVC board and a geotextile, wherein the surface of the PVC board is coated with adhesive, and the geotextile is bonded to the surface of the PVC board by adhesive bonding.

[0010] A PVC waterproof membrane manufacturing device includes a base plate, an adhesive coating box mounted on top of the base plate, a drive mechanism mounted below the base plate, an installation structure mounted on the base plate and in front of the adhesive coating box and driven by the drive mechanism, several adhesive coating sections detachably mounted on the outer side of the installation structure, a rotating base mounted at the top detachable position of the base plate, a drive motor mounted on the top of the rotating base, and several sets of cleaning machines mounted on the outer side of the output end of the drive motor.

[0011] Preferably, a bracket is fixedly installed on the top of the base plate, and a base support is fixedly installed on the top of the base plate and inside the bracket. A guide roller is rotatably connected to the middle of the base support through a bearing. The glue coating box includes a machine body, and a glue groove is opened at the discharge port of the machine body. A plug is fixedly inserted inside the glue groove.

[0012] Preferably, the driving mechanism includes cylinders, and two cylinders are respectively fixedly installed below the left and right ends of the bracket, with a fixed box fixedly installed on the telescopic end of each cylinder.

[0013] Preferably, the mounting structure includes a rotating roller, with both ends of the rotating roller rotatably mounted between two fixed boxes via bearings. Several adhesive application structures are mounted on the outer side of the rotating roller, and each adhesive application structure includes a mesh upper sleeve and a mesh lower sleeve. Positioning strips are fixedly installed on the inner sides of both the mesh upper sleeve and the mesh lower sleeve. Interconnected positioning grooves are formed at the top and bottom of the rotating roller, and one end of each positioning strip is inserted into the positioning groove. Movable grooves are formed inside the rotating roller and on the side of the positioning groove, allowing for sliding within the movable grooves. The device is connected to a convex plate, and guide strips are fixedly installed on the sides of the convex plate. The sides of the positioning strips are provided with interconnected guide grooves, and one end of each guide strip is inserted into the guide groove. The rotating roller is provided with an installation groove at the end of the moving groove. A first short electric telescopic rod is fixedly installed on one side of the inner cavity of the installation groove. The telescopic end of the first short electric telescopic rod is fixedly connected to the side of the convex plate. A first pull rope sensor is fixedly installed inside the installation groove. The pull rope end of the first pull rope sensor is fixedly connected to the tail of the convex plate.

[0014] Preferably, the rotating roller has a fixing groove inside and on the side of the positioning groove. A second short electric telescopic rod is fixedly installed in the inner cavity of the fixing groove. A fixing block is fixedly installed at the telescopic end of the second short electric telescopic rod. A fixing hole is opened on the side of the positioning strip. One end of the fixing block is inserted into the fixing hole. A positioning sensor is fixedly installed on one side of the inner cavity of the fixing groove. A positioning block is embedded on the side of the positioning strip. The positioning block cooperates with the positioning sensor.

[0015] The present invention sets up two sets of positioning mechanisms in the installation structure, which respectively undertake the different functions of guiding and positioning and locking and fixing. The two have clear division of labor and cooperate with each other to achieve precise installation, reliable transmission, safe disassembly and automatic reset of the adhesive structure.

[0016] The first set of positioning mechanisms includes: positioning bar, positioning groove, guide bar, and guide groove. Core functions: circumferential transmission positioning, axial guidance and anti-detachment; The positioning strip and positioning groove work together to achieve circumferential positioning, ensuring that the upper and lower mesh sleeves rotate synchronously with the rotating roller without slipping or eccentricity, thus ensuring uniform glue application.

[0017] The guide bar and guide groove work together to achieve axial guidance and prevent detachment, so that the adhesive sleeve can only move along the axial direction, avoiding detachment, displacement, and jamming.

[0018] The first pull rope sensor monitors displacement in real time to ensure the accuracy of the movement.

[0019] Second positioning mechanism: fixing block, fixing hole, and position sensor. Core functions: radial locking and fixing, and installation positioning detection. The fixing block and the fixing hole cooperate to achieve radial locking, preventing the adhesive sleeve from loosening, shifting, or falling off during high-speed rotation, thus ensuring production safety.

[0020] The positioning sensor works in conjunction with the positioning block to detect whether the assembly is in place in real time, avoiding misalignment, loose clamping, or misalignment, thus improving the stability of equipment operation.

[0021] Preferably, a number of stops are fixedly installed on the outer disassembly position of the rotating roller, one end of the rotating roller extends into the inside of the fixed box, a drive motor is fixedly installed inside the fixed box, and sprockets connected by chain drive are fixedly sleeved on the outer side of the left end of the rotating roller and the outer side of the output end of the drive motor.

[0022] Preferably, a long electric telescopic rod is fixedly installed on the front surface of the fixed box on the left side. A push ring is fixedly connected to the telescopic end of the long electric telescopic rod, and the push ring is sleeved on the outside of the rotating roller. A guide rod is fixedly installed on the outside of the push ring, and one end of the guide rod extends to the outside of the fixed box.

[0023] Preferably, the rotating base includes a fixed base, which is embedded in the top of the waterproof structure. An annular gasket is movably embedded in the top of the fixed base. A drive motor is fixedly installed on the top of the fixed base. Two connecting arms are fixedly installed on the outer side of the output end of the drive motor. A housing is fixedly installed on one end of each connecting arm, and the bottom end of the housing is fixedly connected to the top of the annular gasket. An inner shell is placed inside each housing. The top outer frame of the inner shell is located above the outer shell. A vibration isolation pad is fixedly installed on the top of the outer shell and is located between the outer shell and the inner shell. A top frame is placed inside the inner shell. A filter frame is fixedly fitted on the outer side of the top of the top frame. The outer frame of the filter frame is located above the inner shell. An ultrasonic vibrator is installed at the bottom of the inner cavity of the inner shell. Two pipes are installed on the outer side of the outer shell. One is a wire connected to the ultrasonic vibrator, and the other is a drain pipe. A drain valve is installed at the head end of the drain pipe, and one end of the drain pipe extends into the interior of the inner shell.

[0024] Preferably, guide boxes are fixedly installed on the outer side of the outer shell, and guide blocks are slidably installed inside the guide boxes. The top of each guide block extends to the top of the guide box and is connected to the bottom of the filter frame through a soft pad. A drive box is fixedly installed on the outer side of the housing. A reciprocating screw is rotatably connected inside the drive box via bearings. A top column is threaded to the outer side of the reciprocating screw, and both ends of the top column extend to the top of the drive box and are connected to the bottom of the filter frame via soft pads. The bottom end of the reciprocating screw extends into the fixed seat and is fixedly installed with gears. A first rack and a second rack are fixedly installed inside the fixed seat.

[0025] A method for preparing a PVC waterproof board includes the following steps: S1: The waterproof board is conveyed to the gluing station via guide rollers, and the surface of the PVC board is evenly coated with glue by the textured glue applicator. S2: The geotextile and the adhesive-coated waterproof membrane are combined to form a composite waterproof membrane.

[0026] This invention provides a PVC waterproof board and its preparation equipment and method, which have the following beneficial effects: 1. Compared with the traditional hot melt calendering process of composite geotextile waterproof membrane for tunnels, the present invention adopts the production method of coating the sheet with adhesive to form a composite geotextile. The production process is simpler, the production efficiency is higher, the bonding strength is higher, and it will not cause thermal damage to the physical and mechanical properties of the sheet body and the geotextile. The product has more stable overall performance and stronger durability.

[0027] 2. This invention adopts a segmented coating structure combined with an automatic feeding, automatic unlocking and detachment mechanism and an ultrasonic online cleaning mechanism. The coating sleeve can be replaced, cleaned and recycled while the equipment is running normally. There is no need to disassemble the roller, which completely solves the problem of having to stop the machine to clean all the glue when the traditional anilox roller is blocked, and significantly improves production efficiency and equipment utilization.

[0028] 3. In the existing technology, when disassembling the anilox roller, all the adhesive in the glue tank must be emptied and the inside of the glue tank must be cleaned. The process is cumbersome, time-consuming and labor-intensive. When the coating sleeve is replaced, the glue tank is fixed in place. There is no need to empty the adhesive, clean the glue tank, or disassemble the glue tank. The maintenance steps are greatly simplified and the equipment maintenance time is significantly shortened.

[0029] 4. Traditional roller changing requires discarding all remaining glue in the glue tank, resulting in high glue loss and high raw material costs. In this invention, the glue can be directly retained and reused when changing the coating sleeve, avoiding the waste of raw materials caused by frequent tank cleaning and glue discharge, and effectively reducing production consumable costs.

[0030] 5. Existing technologies require the use of large amounts of cleaning fluid to clean glue tanks, generating a large amount of glue-containing waste liquid, which puts great pressure on environmental protection. This invention eliminates the need to clean glue tanks, reducing the generation of waste liquid and residue from the source, resulting in a cleaner production environment and meeting the requirements of green and environmentally friendly production.

[0031] 6. Through the multi-positioning cooperation of positioning strips, positioning grooves, guide strips and guide grooves, the adhesive sleeve and rotating roller rotate synchronously without slippage or eccentricity, ensuring uniform and stable adhesive application, effectively improving the bonding strength between PVC board and geotextile, reducing defects such as delamination, degumming, and missed coating, and improving the finished product qualification rate.

[0032] 7. Through the cooperation of electric telescopic rods, sensors, drive motors and reciprocating screws, the adhesive sleeve can be automatically unlocked, automatically detached, automatically cleaned, automatically lifted and unloaded, and automatically loaded and positioned. The whole process is automated, eliminating the need for frequent manual disassembly and cleaning, reducing labor intensity and improving operational safety.

[0033] 8. The coating sleeve adopts a segmented and detachable structure. If a single part is damaged or blocked, only the corresponding module needs to be replaced, without replacing the entire coating roller, which greatly reduces the equipment maintenance cost. Ultrasonic cleaning can deeply clean the residual glue in the mesh cells without damaging the mesh structure and extend the service life of the coating sleeve.

[0034] 9. The cleaning box can rotate and change position under the drive motor, and in conjunction with the rack, pinion, reciprocating screw and top column, the filter frame is automatically lifted to facilitate the removal of the cleaned glue sleeve; the other cleaning box rotates into the receiving position at the same time, and the whole process is automatically connected, making the process efficient and smooth.

[0035] 10. The cleaning machine of this invention adopts a layered nested structure of outer shell, vibration isolation pad, inner shell, top frame, and filter frame, and is equipped with a soft pad for flexible connection of the drive and guide mechanism, which has the following significant advantages: The inner and outer shells are separated and a vibration isolation pad is installed in between, which can effectively block the high-frequency vibrations generated by ultrasonic cleaning from being transmitted outward, preventing vibration from being transmitted to the frame, transmission mechanism and the whole structure, reducing equipment operating noise, reducing structural fatigue wear, and significantly improving equipment operating stability and service life.

[0036] The inner shell forms an independent, sealed cleaning chamber that can stably hold the cleaning fluid and directly support the ultrasonic vibrator, enabling comprehensive and thorough cleaning of the coating sleeve without dead angles. It effectively removes residual adhesive from the mesh cells without damaging the mesh structure, ensuring the accuracy of the coating sleeve's reuse and the uniformity of the adhesive application.

[0037] The drive column, guide block and filter frame are connected by soft pads, which can effectively buffer the impact of mechanical transmission, ultrasonic vibration and rigid collision during lifting, avoid damage to the glued sleeve, filter frame and precision transmission guide parts, and improve the safety and durability of equipment operation.

The rotating roller 601 drives the adhesive coating structure 5 to rotate, so that the mesh sleeve 501 and the lower mesh sleeve 502 rotate to pick up the adhesive liquid seeping from the glue tank 302 inside the machine body 301 and apply it to the surface. The mesh pattern on the mesh sleeve 501 and the lower mesh sleeve 502 is then applied to the surface of the PVC board 101. Then the geotextile 102 is bonded to the surface of the PVC board 101 with an adhesive layer; After a period of use, the telescopic end of cylinder 401 drives the fixed box 402 to move upward, so that the fixed box 402 drives the mounting structure 6 and the adhesive application structure 5 to move upward to the cleaning position. Then, the telescopic end of the second short electric telescopic rod 611 corresponding to the lower mesh sleeve 502 on the final adhesive structure 5 drives the fixing block 612 to move out from the fixing hole 613, releasing the positioning and fixing of the positioning strip 603; and the telescopic end of the first short electric telescopic rod 608 drives the convex plate 606 to reset and move, so that the convex plate 606 drives one end of the guide strip 605 to move from the guide groove 617, so that the lower mesh sleeve 502 falls into the top frame 904. Through the ultrasonic vibrator installed in the inner cavity of the inner shell 903, the cleaning fluid inside the filter frame 905 vibrates, cleaning the mesh cavity of the lower mesh sleeve 502. During the cleaning time, the telescopic end of cylinder 401 pushes the fixed box 402, the mounting structure 6, the glue coating structure 5 and the glue coating box 3 to move down, thereby continuing to coat the PVC board 101 with glue. After a period of cleaning, the telescopic end of cylinder 401 moves the fixed box 402 upward, causing the fixed box 402 to move the mounting structure 6 and the adhesive application structure 5 upward to the cleaning position. The output end of the transmission motor 403 drives a sprocket 404 to rotate, which in turn drives the rotating roller 601 to rotate. The rotating roller 601 then rotates the adhesive application structure 5, causing the mesh sleeve 501 to rotate downwards. During this process, the output of the drive motor 8 drives the connecting arm 913 to rotate, which in turn drives the housing 901 to rotate. This causes the housing 901 to slide the annular gasket 702 inside the fixed seat 701. When the housing 901 rotates to the unloading position on the right side of the base plate 2 and moves to the right side of the drive mechanism 4, the first rack 703 drives the gear 912 to rotate, which in turn drives the reciprocating screw 910 to rotate. This causes the reciprocating screw 910 to drive the top column 911 to move upward, which in turn pushes the filter frame 905 upward. This causes the filter frame 905 to move the top frame 904 from inside the inner housing 903. The filter frame 905 also drives the guide block 908 to move upward along the inside of the guide box 907 via the soft pad. This makes it easier to remove the lower mesh sleeve 502 from inside the top frame 904 when the housing rotates to the unloading position on the right side of the base plate 2. As the outer casing 901 moves in a circular motion, another set of outer casings 901 rotates downwards towards the drive mechanism 4. During this rotation, the second rack 704 drives the gear 912 to continue rotating, causing the gear 912 to drive the reciprocating screw 910 to rotate. This causes the reciprocating screw 910 to drive the top column 911, which has reached its uppermost stroke, to move downwards. Consequently, the top column 911, through the soft pad, moves the filter frame 905 and the top frame 904 downwards into the inner casing 903. Then, the telescopic end of the second short electric telescopic rod 611 corresponding to the mesh sleeve 501 drives the fixing block 612 to move out from the inside of the fixing hole 613, releasing the positioning and fixing of the positioning strip 603; and the telescopic end of the first short electric telescopic rod 608 drives the convex plate 606 to reset and move, so that the convex plate 606 drives one end of the guide strip 605 to move from the inside of the guide groove 617, so that the lower mesh sleeve 502 falls into the inside of the top frame 904. Through the ultrasonic vibrator installed in the inner cavity of the inner shell 903, the cleaning fluid inside the filter frame 905 vibrates, cleaning the mesh cavity of the lower mesh sleeve 502. Then, the telescopic end of the second short electric telescopic rod 611 corresponding to the lower mesh sleeve 502 on the adhesive coating structure 5 drives the fixing block 612 to move out from inside the fixing hole 613, releasing the positioning and fixing of the positioning strip 603. Next, the telescopic end of the long electric telescopic rod 405 pushes the push ring 406 to move, which in turn pushes several sections of the adhesive coating structure 5 to move, causing the remaining adhesive coating structure 5 to move towards the disassembly position. This moves the second-to-last adhesive coating structure 5 to the very end, where the stop block 616 limits its movement. Then, the telescopic end of the long electric telescopic rod 405 pulls the push ring 406 to reset. Next, except for the second short electric telescopic rod 611 at the loading position, which remains stationary, the telescopic ends of the other second short electric telescopic rods 611 push the fixing block 612 to move, causing one end of the fixing block 612 to insert into the fixing hole 613, fixing the position of the positioning strip 603. Then, the telescopic end of the first short electric telescopic rod 608 drives the protruding plate 606 and one end of the guide strip 605 to move out of the guide groove 617. Then, the user inserts the positioning strips 603 on the upper and lower mesh sleeves 501 and 502 into the positioning groove 602 at the feeding position of the rotating roller 601. Then, the user pushes the protruding plate 606 and the guide strip 605 to move through the telescopic end of the first short electric telescopic rod 608, so that one end of the guide strip 605 is inserted into the guide groove 617, which limits the positioning strip 603, the upper and lower mesh sleeves 501 and 502. At this time, the positioning strip 603 can only move along the positioning groove 602 and the guide strip 605. Then, the second short electric telescopic rod 611 at the feeding position is activated. The telescopic end of the second short electric telescopic rod 611 pushes the fixing block 612 to move, so that one end of the fixing block 612 is inserted into the fixing hole 613, which fixes the position of the positioning strip 603.
