Description

Technical Field

[0001] This utility model relates to an asphalt waterproof membrane coating device, belonging to the technical field of asphalt waterproof membrane coating. Background Technology

[0002] Bituminous coating is a common method for manufacturing waterproof membranes. It involves applying a layer of bituminous material to a base material to provide waterproofing. The base material of the waterproof membrane is typically made of reinforcing materials such as polyester felt, fiberglass felt, or other synthetic fiber felt to provide the necessary strength and flexibility. Bituminous material, as the coating, offers excellent waterproofing performance and durability.

[0003] Chinese utility model patent CN221951597U discloses a modified bitumen waterproof membrane bitumen coating device. By having the lower and upper cleaning blocks slide back and forth along the upper and lower surfaces of the waterproof membrane, the bitumen coating on the waterproof membrane can be spread evenly after the membrane is coated with bitumen. The back and forth sliding of the scraper can collect excess bitumen from different points on the same plane, allowing the excess bitumen to drip down the side wall of the scraper into the coating groove, making the bitumen coating on the waterproof membrane more uniform and preventing excess bitumen from falling onto the coating blocks.

[0004] The above-mentioned patented solution has the following drawbacks in use: because it is necessary to coat both sides of the base material, multiple guide rollers are configured to make the base material be conveyed in a ring. A coating roller and a material trough are configured on both the upper and lower sides for coating work, which is relatively complicated. Moreover, since the two sides of the base material are coated separately, the coating is easily conveyed to other places with the base material during the coating process, which is difficult to clean.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This invention addresses the shortcomings of the prior art by providing an asphalt waterproof membrane coating device that allows the base material to be coated on both sides simultaneously at the lower end of the upper coating roller. The structure is simpler, avoids paint pollution of the surrounding environment, and makes the coating thickness more uniform.

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] A bitumen waterproof membrane coating device includes a wrapping roller with a base material wound around it and an upper coating roller. A guide roller is provided on the side of the upper coating roller near the wrapping roller. The guide roller presses against the surface of the upper coating roller. The base material conveyed from the wrapping roller is conveyed closely to the surface of the upper coating roller under the guidance of the guide roller.

[0009] The lower end of the upper coating roller is provided with a lower coating roller that is closely attached to it, and the lower end of the lower coating roller is provided with a paint trough;

[0010] The coating roller includes a fixed inner roller and an outer roller that rotates relative to the inner roller. The inner roller has a hollow material holding cavity inside, and the lower end of the inner roller has a strip-shaped material outlet that is opened along the axial direction. The side wall of the outer roller has a plurality of material leakage holes.

[0011] Furthermore, a sealing strip is provided on the outer side of the strip-shaped discharge port.

[0012] Furthermore, one end of the upper coating roller is provided with a feed conveying pipe, which is connected to the material holding cavity of the inner roller.

[0013] Furthermore, an extrusion roller is provided on the side of the upper coating roller away from the wrapping roller, and the extrusion roller is positioned close to the upper coating roller.

[0014] Furthermore, the outer roller of the upper coating roller is provided with annular raised retaining rings at both ends, and the extrusion roller presses on the top of the raised retaining rings.

[0015] Furthermore, it also includes a support, on which the extrusion roller, upper coating roller, guide roller and paint tank are all mounted.

[0016] Furthermore, a scraper is provided on the lower side of the upper coating roller. The two ends of the scraper are hinged to the bracket by connecting rods. A tension spring is also provided on the scraper so that the end of the scraper is close to the surface of the upper coating roller.

[0017] Furthermore, two rolling cleaning rollers are provided between the guide roller and the wrapping roller, arranged vertically to sandwich the base material in the middle.

[0018] Furthermore, a spray nozzle is provided on both the upper and lower sides of the base material between the guide roller and the cleaning roller.

[0019] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0020] The coating is discharged from the strip outlet and applied to the side wall of the outer roller, and then applied to the upper surface of the base material through the discharge hole on the side wall of the outer roller. During the rotation of the lower coating roller, the coating is dipped from the coating tank and applied to the lower surface of the base material. This allows the base material to be coated on both the upper and lower surfaces at the lower end of the lower coating roller, thus avoiding pollution of the surrounding environment during the transfer of the base material.

[0021] The outer roller of the coating roller is provided with annular raised retaining rings at both ends. The extrusion roller presses on the top of the raised retaining rings. The thickness of the waterproof membrane after coating is the height of the raised retaining rings, thus controlling the thickness of the waterproof membrane more precisely.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

A guide roller 4 is provided on the side of the upper coating roller 5 near the wrapping roller 1. The guide roller 4 presses against the surface of the upper coating roller 5. The base material conveyed from the wrapping roller 1 is conveyed closely to the surface of the upper coating roller 5 under the guidance of the guide roller 4.

[0031] The lower end of the upper coating roller 5 is provided with a lower coating roller 8 that is closely attached to it, and the lower end of the lower coating roller 8 is provided with a paint trough 7.

[0032] The upper coating roller 5 includes a fixedly arranged inner roller 12 and an outer roller 13 rotatably arranged relative to the inner roller 12. The inner roller 12 has a hollow material holding cavity inside, and the lower end of the inner roller 12 is provided with a strip-shaped discharge port 1201 opened along the axial direction. Figure 4 The outer roller 13 has multiple material leakage holes arranged on its side wall.

[0033] A sealing strip 14 is provided on the outer side of the strip-shaped discharge port 1201. The sealing strip 14 seals the gap between the outer wall of the inner roller 12 and the inner wall of the outer roller 13 to prevent the material liquid in the material holding cavity of the inner roller 12 from leaking out.

[0034] One end of the upper coating roller 5 is provided with a feed conveying pipe 16, which is connected to the material holding cavity of the inner roller 12. The coating material is conveyed into the upper coating roller 5 through the feed conveying pipe 16.

[0035] The upper coating roller 5 is provided with a pressing roller 9 on the side away from the wrapping roller 1, and the pressing roller 9 is arranged close to the upper coating roller 5.

[0036] The outer roller 13 of the upper coating roller 5 is provided with annular protruding retaining rings 15 at both ends, such as Figure 2 and Figure 3 The waterproof membrane is conveyed between two raised retaining rings 15, and the extrusion roller 9 presses on the top of the raised retaining rings 15.

[0037] This utility model also includes a bracket 6, on which the extrusion roller 9, upper coating roller 5, guide roller 4 and coating tank 7 are all mounted.

[0038] The upper coating roller 5 is also provided with a scraper 10 on its lower side. The two ends of the scraper 10 are hinged to the bracket 6 through connecting rods. The scraper 10 is also provided with a tension spring 11, so that the end of the scraper 10 is close to the surface of the upper coating roller 5 to scrape off the excess coating on the lower surface of the base material.

[0039] Two rolling cleaning rollers 2 are also provided between the guide roller 4 and the winding roller 1. The two cleaning rollers 2 are arranged vertically to sandwich the base material in the middle and clean the impurities on the surface of the base material.

[0040] A spray pipe 3 is provided on the upper and lower sides of the base material between the guide roller 4 and the cleaning roller 2. The spray pipe 3 sprays primer (adhesive) onto the base material to facilitate the coating of the roller.

[0041] The specific working principle of this utility model:

[0042] Guided by the guide roller 4, the base material adheres to the lower surface of the upper coating roller 5 for transmission; the upper coating roller 5 includes a fixed inner roller 12 and an outer roller 13 that rotates relative to the inner roller 12. The inner roller 12 has a hollow material-holding cavity inside, and the lower end of the inner roller 12 is provided with a strip-shaped discharge port 1201 opened along the axial direction, such as... Figure 4 The outer roller 13 has multiple material leakage holes on its side wall.

[0043] The coating is fed into the upper coating roller 5 through the feed pipe 16. When the base material rotates to the lower end of the upper coating roller 5, the coating leaks out from the strip outlet 1201 and is applied to the side wall of the outer roller 13. It is also applied to the upper surface of the base material through the leakage hole on the side wall of the outer roller 13. During the rotation of the lower coating roller 8, the coating is dipped from the coating tank 7 and applied to the lower surface of the base material. This allows the base material to be coated on both the upper and lower surfaces at the lower end of the lower coating roller 8, thus avoiding pollution of the surrounding environment during the transport of the base material.

[0044] The upper coating roller 5 and the outer roller 13 are respectively provided with annular raised retaining rings 15 at both ends. The extrusion roller 9 presses on the top of the raised retaining rings 15. The thickness of the waterproof membrane after coating is the height of the raised retaining rings 15, thereby controlling the thickness of the waterproof membrane more precisely.
