[0034] As shown in the figure, this embodiment of the invention provides an adhesive coating device for a reverse-adhesive waterproof membrane, including a first frame 11, a second frame 12, and a top plate 13, wherein the top plate 13, the first frame 11, and the second frame 12 are fixedly connected.

[0035] In related technologies, existing waterproof membrane adhesive coating production equipment has a complex structure, with the feeding unit, front storage unit, adhesive coating and edge film covering unit, water-based adhesive coating unit, drying oven unit, film covering unit, rear storage unit, and winding unit arranged in a straight line, requiring a large space. This invention, through a guiding component, allows the waterproof membrane substrate to move along a C-shaped trajectory, thereby effectively utilizing vertical space and solving the problem of large equipment space requirements.

[0036] According to an embodiment of the present invention, the guiding assembly includes: a first guiding assembly 34 disposed on the second frame 12 for causing the waterproof membrane substrate to contact the upper surface of the adhesive roller 32; a second guiding assembly 7 disposed on the top plate 13 for causing the waterproof membrane substrate to contact the lower surface of the coating roller 4; and a third guiding assembly 8 disposed on the first frame 11 for causing the waterproof membrane substrate to move from the upper part of the first frame 11 to the lower part of the first frame 11.

[0037] According to an embodiment of the present invention, the first guiding component 34 includes: a first guiding roller 341, the lowest point of which is lower than the highest point of the adhesive roller 32; and a first reversing roller 342, which is flush with the height of the first guiding roller 341, and the waterproof substrate is turned to the coating roller 4 via the first reversing roller 342.

[0038] According to an embodiment of the present invention, the second guide assembly 7 includes: a second guide roller 71, the highest point of which is higher than the lowest point of the coating roller 4; and a second reversing roller 72, which is flush with the height of the second guide roller 71, and the waterproof substrate is turned to the first frame 11 via the second reversing roller 72.

[0039] According to an embodiment of the present invention, the third guide assembly 8 includes: a third guide roller 81 located at the upper part of the first frame 11; and a third reversing roller 82 located at the lower part of the first frame 11, wherein the waterproof membrane substrate is turned to the tensioning member 6 via the third reversing roller 82.

[0040] According to an embodiment of the present invention, it further includes: a crossbar 14 located below the top plate 13 and fixedly connected to the first frame 11 and the second frame 12; and a feeding roller 2 disposed on the crossbar 14 for conveying the waterproof board substrate to the adhesive roller 32.

[0041] According to an embodiment of the present invention, the guiding assembly further includes a guide frame 35, which is disposed between the feeding roller 2 and the coating roller 32 and is fixedly connected to the second frame 12.

[0042] According to an embodiment of the present invention, a hot air outlet hood 9 is also included, which is disposed between the coating roller 32 and the film coating roller 4 and is fixedly connected to the second frame 12.

[0043] In this embodiment of the invention, a hot air supply pipe is connected to the hot air outlet hood 9, and hot air is blown through the hot air outlet hood 9 onto the waterproof board substrate coated with colloid.

[0044] According to an embodiment of the present invention, a take-up roller is also included, which is installed on one side of the tensioner 6 and is at a lower height than the tensioner 6.

[0045] According to an embodiment of the present invention, the coating roller 32 includes: a shaft 322 mounted on the second frame 12; and a roller body 321 sleeved on the outside of the shaft 322, and having the same linear velocity as the take-up roller.

[0046] Specifically, a U-shaped groove is provided on the crossbar 14, and the end of the feeding roller 2 is placed inside the U-shaped groove; the first frame 11 and the second frame 12 are both rectangular frame structures with the same height; the first frame 11 and the second frame 12 are both constructed by splicing U-shaped steels, and different U-shaped steels can be connected by using corner brackets and bolts, or they can be fixedly connected by welding at the joints of the U-shaped steels.

[0047] The tensioning component 6 includes a guide roller 61, a sleeve rod 62, and a right-angle seat 64. Long grooves 121 are installed on both sides of the second frame 12. The guide roller 61 located inside the second frame 12 extends outward through the long grooves 121 at both ends. The sleeve rod 62 is sleeved on the end of the guide roller 61. The right-angle seat 64 is installed on the outer surface of the second frame 12. The bottom end of the guide roller 61 passes through the guide hole on the right-angle seat 64. A spring 63 is sleeved on the sleeve rod 62.

[0048] like Figures 6-10As shown, the coating section 3 includes a trough 31 and a coating roller 32. The trough 31 is installed inside the second frame 12. A guide frame 35 is installed on the side of the trough 31 near the feeding roller 2. The coating roller 32 includes a roller body 321 and a shaft 322. The roller body 321 is sleeved on the outside of the shaft 322 and is located inside the trough 31. The two ends of the roller body 321 are respectively installed on opposite sides of the second frame 12. A speed-changing wheel 33 is installed on the input end of the roller body 321. A first guide assembly is provided above the trough 31, and the first guide assembly is located on both sides of the roller body 321. The waterproof substrate on the feeding roller 2 passes through the guide frame 35 and the... The first guide assembly, because the height of the first guide roller 341 and the first reversing roller 342 is lower than the uppermost position of the roller body 321, passes over the waterproof substrate of the first guide roller 341 and the first reversing roller 342, and also passes over the upper surface of the roller body 321. The speed-changing wheel 33 is connected to the drive motor via a belt. The drive motor can be mounted on the top plate 13. The motor drives the speed-changing wheel 33 and the shaft 322 to rotate via the belt. Adhesive material is placed in the trough 31. When the shaft 322 drives the roller body 321 to rotate in the trough 31, the adhesive material is coated onto the surface of the roller body 321 and applied to the waterproof substrate, thus achieving the adhesive application step. The tube body 36 has a hollow structure, and both ends of the tube body 36 are provided with connecting pipes. One end of the tube body 36 is connected to a hot water supply pipe, and the other end of the tube body 36 is connected to a hot water discharge pipe.

[0049] In related technologies, uneven adhesive adhesion is easily generated during the application of adhesive to the waterproof membrane substrate. In this embodiment of the invention, the waterproof membrane substrate is heated with hot water, which promotes the adhesion of the adhesive material. In addition, the pipe body 36 is heated with hot water, which makes the heating more uniform and avoids the problem of large temperature differences in different parts of the waterproof membrane substrate.

[0050] like Figures 11-12As shown, the speed-changing wheel 33 includes a driven wheel 331 sleeved on the shaft 322. The driven wheel 331 and the driving wheel 333 are connected by a plurality of planetary gears 332. The outer side of the driving wheel 333 is provided with a belt groove for connecting to a belt. The driving wheel 333 is driven by the planetary gears 332 and the driven wheel 331 to achieve deceleration. The rotating driven wheel 331 drives the shaft 322 to rotate synchronously. The driven wheel 331 and the shaft 322 are connected by a key. At the same time, the linear velocity of the roller 321 on the shaft 322 is the same as the linear velocity of the take-up roller. A scraper 3 is installed in the groove 31 for scraping the adhesive material on the surface of the roller 321. 7. The scraper component 37 includes two side plates 371, which are sleeved on the shaft 322. The side plates 371 are connected to the inner wall of the groove 31 by screws. Several scrapers 372 and inclined plates 373 are installed between the two side plates 371. The scrapers 372 and inclined plates 373 are alternately distributed. The scrapers 372 gradually approach the surface of the roller 321 from bottom to top. The inner side of the scraper 372 is provided with convex ribs 3721 symmetrically distributed along the center line. The convex ribs 3721 cause the adhesive material flowing inside the scraper 372 to flow down along the convex ribs 3721, avoiding the adhesive material from accumulating on one side and flowing down.

[0051] like Figure 9 As shown, the distance between point b of the auxiliary line and the surface of the roller 321 is greater than the distance between point a of the auxiliary line and the surface of the roller 321. At the same time, the working ends of several scrapers 372 are all located on the auxiliary line, thereby enabling multiple scrapers 372 to gradually reduce the thickness of the adhesive material adhering to the surface of the roller 321. This solves the problem that when a single scraper 372 is working, the thickness of the adhesive scraped at one time is large, which easily causes the adhesive material scraped off to pull off the adhesive material adhering to the surface of the roller 321, resulting in adhesive leakage.

[0052] The scraped adhesive material flows outward along the concave surface of the scraper 372. The adhesive material flowing out from the upper scraper 372 falls onto the inclined plate 373, preventing the adhesive material flowing from the upper scraper 372 from falling onto the upper scraper 372 and solving the problem of adhesive material accumulating on the upper surface of the lower scraper 372, which requires regular manual cleaning.

[0053] like Figure 13As shown, the coating roller 4 includes a column 41, a rod 42 installed inside the column 41, and a mounting seat 43 installed at the end of the rod 42. A rectangular hole 131 is opened in the middle of the top plate 13, and mounting seats 43 are installed on both sides of the rectangular hole 131. The column 41 passes through the rectangular hole 131 to squeeze the waterproof board substrate to be processed. A feeding rack 5 is installed on one side of the rectangular hole 131. The column 41 includes an outer cylinder 411, an inner cylinder 412 located inside the outer cylinder 411, and a baffle 413 for connecting the outer cylinder 411 and the inner cylinder 412. The baffle 413 divides the annular cavity between the outer cylinder 411 and the inner cylinder 412 into several equal parts. Both ends of the annular cavity are equipped with cover plates 417. The outer cylinder 411 and the inner cylinder 412 are respectively provided with several first through grooves 415 and second through grooves 416. The rod 42 is a tube structure with one end closed. The rod 42 has an opening 421 located inside the inner cylinder 412. The unclosed end of the rod 42 is provided with an interface 422. Two retaining rings 414 are sleeved on the outer side of the outer cylinder 411 to limit the passing membrane.

[0054] In this embodiment of the invention, a coating roller coats the surface of a waterproof membrane substrate after it has been coated with adhesive. The film is placed on the outer cylinder 411. Since the interface 422 is connected to the inlet end of the vacuum pump and the openings 421 are distributed upwards, the upper cavity is connected to the inside of the rod 42 through the second through groove 416 and the openings 421. Under the action of the vacuum pump, the film is adsorbed onto the upper surface of the outer cylinder 411. The film moves along the surface of the outer cylinder 411 to the lower side and contacts the waterproof membrane substrate. Through the extrusion of the outer cylinder 411, the film is adhered to the adhesive-coated surface of the waterproof membrane substrate. The moving waterproof membrane substrate drives the outer cylinder 411 to rotate, and the rotating outer cylinder 411 drives the film to move to one side of the waterproof membrane substrate.

[0055] After the waterproof membrane substrate has been coated, it passes through the third guide component, which makes it easier for staff to observe the waterproof membrane substrate and understand the coating condition of the waterproof membrane substrate after the adhesive is applied.

[0056] The invention has the following effects:

[0057] (1) The waterproof membrane substrate moves along a C-shaped trajectory, thereby effectively utilizing the height space and reducing the space occupied by the equipment.

[0058] (2) One end of the pipe is connected to a hot water supply pipe, and the other end of the pipe is connected to a hot water discharge pipe. The hot water heats the waterproof substrate, which promotes the adhesion of the adhesive material. In addition, the hot water heats the pipe, making the heating more even and avoiding the problem of large temperature differences in different parts of the waterproof substrate.

[0059] (3) The working ends of several scrapers are all located on the auxiliary line, thereby enabling multiple scrapers to gradually reduce the thickness of the adhesive material on the roller surface, solving the problem that when a single scraper works, the thickness of the adhesive scraped at one time is large, which easily causes the adhesive material scraped off to cause the adhesive material attached to the roller surface to fall off, easily resulting in adhesive leakage.

[0060] (4) The scraped adhesive material flows outward along the concave surface of the scraper. The adhesive material flowing out from the upper scraper falls onto the inclined plate, which avoids the adhesive material flowing from the upper scraper falling onto the upper scraper and solves the problem of adhesive material accumulating on the upper surface of the lower scraper, which requires manual cleaning periodically.

[0061] The above embodiments are merely examples to clearly illustrate the present invention and are not intended to limit the implementation of the invention. Those skilled in the art can make other variations or modifications based on the following description, and these variations, modifications, substitutions, and alterations arising from the principles and spirit of the present invention still fall within the protection scope of the present invention.
