Description

Technical Field

[0001] This utility model relates to the field of self-adhesive waterproof membrane technology, and in particular to a self-adhesive waterproof membrane coating equipment. Background Technology

[0002] Self-adhesive waterproof membrane, as one of the core materials in building waterproofing projects, is widely used in roofs, basements, kitchens, and bathrooms. Its waterproofing performance directly depends on the quality of the adhesive coating on the membrane surface—ensuring uniform coating, consistent thickness, and a tight bond between the adhesive and the membrane substrate. Currently, the self-adhesive waterproof membrane coating equipment used in the industry still suffers from several technical challenges, making it difficult to meet the demands for efficient and high-quality production. Specific problems include: Poor adaptability to conveying and height: The conveying mechanisms (such as conveyor belts and drive roller assemblies) of existing adhesive coating equipment are mostly of fixed height, which cannot be flexibly adjusted according to the thickness of the self-adhesive waterproof membrane (common thickness range of 0.5-3mm). When processing membranes of different thicknesses, the fixed spacing between the conveying mechanism and the adhesive spraying and coating components can easily lead to insufficient adhesive pressure for thin membranes (poor adhesive adhesion) and excessive adhesive pressure for thick membranes (adhesive is squeezed out), directly affecting the uniformity of adhesive coating.

[0003] Insufficient uniformity of adhesive spraying: Some equipment uses a single nozzle or non-uniformly distributed nozzle design for the adhesive spraying components, and the adhesive supply pressure is unstable (mostly relying on gravity supply, without an active pressure boosting mechanism), which leads to problems such as "local adhesive accumulation" (easily forming adhesive nodules, affecting the flatness of the roll material) or "local adhesive deficiency" (easily creating weak points in waterproofing) on ​​the surface of the roll material, requiring subsequent manual adhesive replenishment, increasing process costs.

[0004] Improper handling of excess glue after application: After the glue roller applies the glue, excess glue often remains on the surface of the roll material. However, existing equipment lacks a precise and controllable glue scraping mechanism – either the scraper height is fixed (which cannot adapt to different glue thickness requirements), or there is no dedicated glue recycling structure. Excess glue either drips into the equipment (causing component contamination and increasing cleaning difficulty) or is directly discarded, which increases production costs and pollutes the production environment.

[0005] Low level of automation and cumbersome operation: The height adjustment and glue scraping gap adjustment of existing equipment mostly rely on manual operation (such as adjustment by bolts and shims), with low adjustment accuracy (error can reach more than 0.5mm), and the machine needs to be stopped for adjustment, resulting in low production efficiency; at the same time, the lack of a coordinated control drive system makes it impossible to accurately match the conveying speed, glue spraying amount and glue coating speed, which easily leads to coordination problems such as "fast conveying, slow glue spraying" (local glue shortage) or "slow conveying, fast glue spraying" (local glue accumulation).

[0006] In summary, the shortcomings of existing self-adhesive waterproof membrane coating equipment in terms of "adaptability, uniformity, economy, and automation" have become key factors restricting the production quality and efficiency of self-adhesive waterproof membranes. There is an urgent need to design a coating equipment that is flexible, uniformly coated, efficiently recyclable, and highly automated to solve the above-mentioned technical pain points. Utility Model Content

[0007] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a self-adhesive waterproof membrane coating equipment.

[0008] One of the objectives of this utility model is achieved through the following technical solution: A self-adhesive waterproof membrane coating device includes four supporting rectangular cylinders and two connecting plates. The two connecting plates are arranged side by side, and the supporting rectangular cylinders are fixedly connected to the front and rear sides of the two connecting plates. Rectangular support rods pass through the inner cavity of the supporting rectangular cylinders. A conveying mechanism is provided between the two rectangular support rods, and an adjusting mechanism is provided between the two front and rear rectangular support rods. A spraying mechanism and a coating mechanism are respectively provided on the top of the conveying mechanism from front to back.

[0009] Furthermore, the adjustment mechanism includes two horizontal plates arranged front to back. The front and rear sides of the two horizontal plates are respectively fixedly connected to adjacent supporting rectangular tubes. A reinforcing plate is fixedly connected between two rectangular support rods arranged on the left and right. A first threaded hole is opened at the center of each of the two reinforcing plates. A threaded rod matching its internal thread passes through the inner cavity of each of the two first threaded holes. The bottom end of the threaded rod passes through the top of the adjacent horizontal plate and is movably connected to it.

[0010] Furthermore, a stop block is fixedly connected to the top of each of the two threaded rods, and a first servo motor is fixedly connected to the middle of the bottom of each of the two horizontal plates. The power output shafts of the two first servo motors are respectively fixedly connected to the bottom end of the adjacent threaded rods.

[0011] Furthermore, the conveying mechanism includes two drive rollers, with a conveyor belt sleeved between them. A drive shaft passes through the center of each drive roller and is fixedly connected to it. The front and rear ends of the two drive shafts are movably connected to the side walls of adjacent rectangular support rods, respectively. The left end of each drive shaft passes through the side wall of the rectangular support rod located on the left side and is movably connected to it. A drive motor is fixedly connected to the left side of each of the two rectangular support rods located on the left side, and the power output shafts of the two drive motors are fixedly connected to the left ends of the adjacent drive shafts, respectively.

[0012] Furthermore, the glue spraying mechanism includes two connecting rods arranged left and right. The bottom ends of the two connecting rods are respectively fixedly connected to the top of adjacent connecting plates. The top of each of the two connecting rods is fixedly connected to a fixing plate. A glue conveying plate is fixedly connected between the two fixing plates. Glue spraying heads are evenly fixedly connected to the bottom of the glue conveying plate. A glue tank is fixedly connected to the middle of the top of the glue conveying plate. The glue tank is connected to the glue conveying plate through a conveying pipe. A pump body is fixedly connected to the top of the glue conveying plate. The pump body is connected to the glue tank through a connecting pipe.

[0013] Furthermore, the glue application mechanism includes two fixed connecting plates arranged side by side. The bottom of each fixed connecting plate is fixedly connected to the top of the adjacent connecting plate. A glue application roller is provided between the two fixed connecting plates. A connecting shaft passes through the center of the glue application roller. The right end of the connecting shaft is movably connected to the left side of the right fixed connecting plate. The left end of the connecting shaft is movably connected to the side wall of the left fixed connecting plate. A glue application motor is fixedly connected to the left side wall of the left fixed connecting plate. The power output mechanism of the glue application motor is fixedly connected to the left end of the connecting shaft. A glue scraping mechanism is provided at the top of the glue application mechanism.

[0014] Furthermore, the adhesive scraping mechanism includes a sliding groove formed on one side of the two fixed connecting plates near the top. The inner cavity of each of the two sliding grooves is slidably connected to a slider. One side of each of the two sliders is fixedly connected to a connecting rod. A scraper is fixedly connected between the two connecting rods.

[0015] Furthermore, a second threaded hole is provided on the slider on the left side. A miniature lead screw that matches the internal thread of the second threaded hole passes through the inner cavity of the second threaded hole. The bottom end of the miniature lead screw is movably connected to the bottom of the inner cavity of the slide groove, and the top end of the miniature lead screw passes through the top of the slide groove and is movably connected to it. A second servo motor is fixedly connected to the top of the fixed connecting plate on the left side, and the power output shaft of the second servo motor is fixedly connected to the top end of the miniature lead screw.

[0016] Furthermore, a collection box is provided at the bottom of the conveyor belt, and a material collection box is provided at the rear side of the conveyor belt. The material collection box is used to collect the solid glue scraped off by the scraper.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up an adjustment mechanism consisting of a first servo motor, a threaded rod, a reinforcing plate, and a rectangular support rod, the height of the conveying mechanism can be automatically and precisely adjusted. During operation, the first servo motor drives the threaded rod to rotate. The threaded rod engages with the first threaded hole on the reinforcing plate, driving the rectangular support rod (fixed to the conveying mechanism) to move up and down along the inner cavity of the supporting rectangular cylinder. The adjustment accuracy can reach 0.1mm, which can adapt to self-adhesive waterproof membranes with a thickness of 0.5-3mm. At the same time, the front and rear adjustment mechanisms operate synchronously to ensure the horizontal lifting and lowering of the conveying mechanism, avoiding uneven glue application caused by tilting, and completely solving the problem of "poor compatibility with membranes of different thicknesses".

[0018] 2. Glue spraying stage: The structure of "glue tank + pump body + glue conveying plate + evenly distributed glue spraying head" is adopted. The pump body draws glue from the glue tank through the connecting pipe and pressurizes it. The glue is then distributed to the evenly distributed glue spraying head at the bottom through the glue conveying plate (the spacing can be designed according to the width of the roll material, such as setting 1 spraying head every 10cm). This achieves "high pressure, uniform and quantitative" glue spraying and avoids local glue accumulation or glue shortage. Adhesive application stage: The adhesive application motor drives the adhesive application roller to rotate, and performs a second rolling coating on the surface of the sprayed roll material, further spreading and compacting the adhesive to ensure that the adhesive is tightly bonded to the roll material substrate. The thickness deviation of the adhesive coating can be controlled within 0.05mm, which significantly improves the adhesive coating quality of the waterproof roll material.

[0019] 3. A scraping mechanism consisting of a second servo motor, a micro lead screw, a slider, and a scraper is set up. The second servo motor drives the micro lead screw to rotate, which in turn moves the slider up and down along the groove, thereby adjusting the gap between the scraper and the coating roller / roll surface (which can be adapted to coating thickness requirements of 0.1-1mm), accurately scraping off excess glue and ensuring that the glue thickness on the roll surface is consistent. High-efficiency recycling: Adhesive drips during spraying and applying are recovered through the collection box at the bottom of the conveyor belt, and solid adhesive (or viscous adhesive) scraped off by the scraper is recovered through the collection box at the rear of the conveyor belt. The adhesive recycling rate can reach more than 85%, which greatly reduces the adhesive waste rate and avoids adhesive contamination of equipment parts, reducing the amount of cleaning work.

[0020] 4. The glue application motor of the glue application mechanism and the second servo motor of the glue scraping mechanism can be linked in coordination through the control system. The conveying speed, glue spraying volume (controlled by the pump speed), glue application speed, and glue scraping gap can be preset according to production needs without manual intervention. This achieves integrated production of "continuous feeding - automatic glue spraying - automatic glue application - automatic glue scraping - automatic recycling". Compared with existing equipment, the production efficiency is increased by more than 30%, and errors caused by manual operation are avoided, ensuring the consistency of batch product quality.

[0021] 5. The main body of the equipment adopts a frame structure of "supporting rectangular cylinder + connecting plate + reinforcing plate", which has high strength and good stability and can withstand the load of long-term continuous operation. All moving parts (such as the connection between the drive shaft and the rectangular support rod, and the connection between the connecting shaft and the fixed connecting plate) adopt a movable connection design, which is easy to disassemble and replace after wear. At the same time, the glue box, collection box and material collection box are all open or detachable structures, which facilitate glue addition and waste cleaning, reducing the difficulty and cost of equipment maintenance.

[0028] This embodiment takes the adhesive coating production of SBS modified bitumen self-adhesive waterproof membrane (a commonly used specification in the industry) with a thickness of 1.5mm as an example.

[0029] I. Equipment Structure Assembly and Parameter Setting (a) Assembly of support and adjustment mechanisms Basic frame construction: Take four supporting rectangular tubes 1 and fix them to the front and rear sides of two connecting plates 2 set on the left and right respectively (each connecting plate 2 has one supporting rectangular tube 1 at the front and rear ends) to form the bottom support frame of the equipment; take two horizontal plates 3 set on the front and rear respectively, and weld the two ends of the horizontal plates 3 to the outer wall of the adjacent supporting rectangular tubes 1 respectively, so that the horizontal plates 3 are horizontally erected between the supporting rectangular tubes 1.

[0030] Adjustment component installation: Take two rectangular support rods 7 arranged on the left and right, and weld and fix a reinforcing plate 19 between the two rectangular support rods 7 (one reinforcing plate 19 corresponds to each rectangular support rod 7 on each side), and open a first threaded hole 20 at the center of the reinforcing plate 19; take two threaded rods 22, pass them through the first threaded hole 20 respectively, and then move their bottom ends into the reserved holes of the horizontal plate 3 (the movable connection is achieved through bearings), and weld a stop block 29 to the top end (to prevent the threaded rods 22 from coming off the first threaded hole 20); fix the first servo motor 21 at the bottom middle of the horizontal plate 3 with bolts, and fix the power output shaft of the first servo motor 21 to the bottom end of the threaded rod 22 through a coupling.

[0031] Adjustment parameter settings: Based on the requirement of 1.5mm thick SBS roll material, set the rotation parameters of the first servo motor 21 (5 revolutions forward) to drive the threaded rod 22 to rotate. Through the meshing transmission between the threaded rod 22 and the first threaded hole 20, the rectangular support rod 7 is driven to move upward along the inner cavity of the support rectangular cylinder 1, so that the distance between the conveying mechanism at the top of the rectangular support rod 7 and the subsequent glue spraying and coating components is maintained at 3mm (to ensure that the roll material passes smoothly and the glue coating pressure is moderate).

[0032] (II) Assembly and parameter setting of the conveying mechanism Conveying assembly installation: Take two drive rollers and fit a conveyor belt 4 (made of heat-resistant rubber, 1.2m wide, suitable for common roll widths) on the outside of the two drive rollers; pass through and weld the drive shaft 6 through the center of each drive roller and fix it in place; connect the front and rear ends of the drive shaft 6 to the pre-drilled holes on the side wall of the rectangular support rod 7 through bearings (the left end of the left drive shaft 6 needs to extend out of the left rectangular support rod 7); fix two drive motors 5 to the left side wall of the left rectangular support rod 7 with bolts, and fix the power output shaft of the drive motor 5 to the left end of the drive shaft 6 through a coupling.

[0033] Conveying parameter settings: The speed of the drive motor 5 is set to 150 r / min, which drives the transmission roller to rotate through the transmission shaft 6, thereby driving the conveyor belt 4 to run at a constant speed of 2 m / min (this speed is matched with the subsequent glue spraying and coating speed to avoid roll material accumulation or stretching).

[0034] (III) Assembly and parameter setting of the glue spraying mechanism Installation of the glue spraying assembly: Take two connecting rods 9 positioned on the left and right, and fix their bottom ends to the top of the connecting plate 2 (corresponding to the position above the front end of the conveyor belt 4) with bolts; weld the fixing plate 10 to the top of the connecting rods 9, and weld the glue conveying plate 11 (1.2m in length, consistent with the width of the conveyor belt 4) between the two fixing plates 10; evenly install glue spraying heads 18 (10cm spacing, 12 in total, using fan-shaped nozzles) at the bottom of the glue conveying plate 11; fix the glue tank 12 (50L capacity, containing hot melt pressure-sensitive adhesive) to the middle of the top of the glue conveying plate 11 with bolts, and connect the outlet of the glue tank 12 to the inlet of the glue conveying plate 11 through a conveying pipe (high temperature resistant hose); fix the pump body 13 to one side of the top of the glue conveying plate 11 with bolts, and connect the pump body 13 to the glue tank 12 through a connecting pipe to form a glue circulation supply path.

[0035] Glue spraying parameter settings: Set the working pressure of pump body 13 to 0.3MPa. The hot melt pressure-sensitive adhesive (heated to 120℃ and kept fluid) in glue tank 12 is drawn by pump body 13 to glue conveying plate 11 and evenly sprayed onto the surface of SBS roll material on conveyor belt 4 through glue spraying head 18. The glue spraying amount is controlled to 80g / m² (which meets the glue coating amount standard of SBS roll material).

[0036] (iv) Assembly and parameter setting of the glue application and scraping mechanisms Installation of the glue application assembly: Take two fixed connecting plates 16 arranged on the left and right, and fix their bottom ends to the top of the connecting plate 2 (corresponding to the rear end of the conveyor belt 4, located behind the glue spraying mechanism) with bolts; set a glue application roller 17 (1.2m in length, smooth surface, made of chrome-plated material) between the two fixed connecting plates 16, and weld a connecting shaft through the center of the glue application roller 17. The right end of the connecting shaft is movably connected to the left reserved hole of the right fixed connecting plate 16 through a bearing, and the left end movably protrudes out of the left fixed connecting plate 16; fix the glue application motor 15 to the left side wall of the left fixed connecting plate 16 with bolts, and fix the power output shaft of the glue application motor 15 to the left end of the connecting shaft through a coupling.

[0037] Installation of the adhesive scraping assembly: A vertical groove 25 (10cm long) is made near the top on one side of the two fixed connecting plates 16. A slider 27 (with clearance fit with the groove 25, allowing it to slide up and down) is embedded in the groove 25. A connecting rod is welded to one side of the two sliders 27. A scraper 28 (1.2m long, with a stainless steel blade, parallel to the adhesive roller 17) is fixed between the connecting rods by bolts. A second threaded hole 26 is made on the left slider 27. A miniature lead screw 24 is passed through the second threaded hole 26, with its bottom end movably connected to the bottom of the groove 25 cavity via a bearing, and its top end movably protruding from the top of the groove 25. A second servo motor 23 is fixed to the top of the left fixed connecting plate 16 by bolts. The power output shaft of the second servo motor 23 is fixedly connected to the top of the miniature lead screw 24 via a coupling.

[0038] Glue application and scraping parameter settings: Set the speed of the glue application motor 15 to 150 r / min, drive the glue application roller 17 to rotate clockwise (in the same direction as the conveyor belt 4), and perform secondary rolling coating on the sprayed glue on the surface of the roll material to ensure that the glue penetrates evenly and is compacted; Set the rotation parameters of the second servo motor 21 (reverse 2 revolutions), drive the micro lead screw 24 to rotate, and drive the slider 27 to move downward along the slide groove 25, so that the gap between the blade of the scraper 28 and the surface of the glue application roller 17 is maintained at 0.2 mm (precisely scrape off excess glue from the surface of the glue application roller 17 to ensure that the glue coating thickness of the roll material is consistent).

[0039] (v) Installation of recycled components A collection box 8 (20L capacity, open at the top, with an anti-stick coating on the inner wall) is placed at the bottom of the conveyor belt 4 (below the glue spraying mechanism and the glue coating mechanism) to collect a small amount of glue that drips during the glue spraying process; a collection box 14 (10L capacity, open at the top, aligned with the position of the scraper 28) is placed on the rear side of the conveyor belt 4 (below the glue coating roller 17) to collect excess solid glue scraped off by the scraper 28 (which can be crushed and reheated after cooling).

[0040] II. Equipment Workflow Preliminary preparation: Add hot melt pressure-sensitive adhesive to glue tank 12, and start the heating device of glue tank 12 (not mentioned in the document, supplemented according to actual production, to ensure that the glue temperature is stable at 120℃); start the first servo motor 21 and adjust the height of the rectangular support rod 7 to the preset position; start the second servo motor 23 and adjust the gap between the scraper 28 and the glue coating roller 17 to 0.2mm.

[0041] Roll conveying and gluing: Place one end of a 1.5mm thick SBS self-adhesive waterproof roll at the front end of the conveyor belt 4, start the drive motor 5, and the conveyor belt 4 moves the roll backward at a speed of 2m / min; when the roll moves to the bottom of the glue spraying mechanism, start the pump body 13, and the glue is evenly sprayed onto the surface of the roll through the glue spraying head 18; when the roll continues to move to the bottom of the gluing mechanism, the glue spraying motor 15 drives the glue spraying roller 17 to rotate, and roll the glue onto the surface of the roll. At the same time, the scraper 28 scrapes off the excess glue on the surface of the glue spraying roller 17, and the scraped glue falls into the collection box 14; the glue dripping during the glue spraying process falls into the collection box 8.

[0042] Finished product output and recycling: The coated rolls are output from the rear end of conveyor belt 4 and enter the subsequent drying process; after production is completed, the dripping glue in collection box 8 is collected (filtered and added back to glue box 12) and the scraped glue in collection box 14 is crushed, heated and melted, and added back to glue box 12.

[0043] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model.
