BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0016] Combine the following Figure 1 The technical solution of the utility model is further illustrated by specific embodiments.

[0017] like Figure 1 The waterproof coil carrier cloth coating device shown is used for coating and cooling the carrier cloth 5, and includes: a base 1, a first guide roller 6, a coating roller 3, a second guide roller 9, an oil coating box 2, a wind knife 8, a wind box 11 and an arc scraper 14. The oil coating box 2 is arranged on the base 1, and the base 1 is provided with a frame 4 extending to the top of the oil coating box 2. The coating roller 3 is horizontally arranged in the oil coating box 2. In this embodiment, the oil coating box 2 is provided with waterproof asphalt that immerses the bottom of the coating roller 3, so as to facilitate the coating of the carrier cloth 5 passing through the bottom of the coating roller 3.

[0018] The first guide roller 6 is arranged on the frame 4 and is located above the rear side of the coating roller 3. The carrier cloth 5 enters the oil coating box 2 through the first guide roller 6 and is coated with waterproof asphalt when passing through the bottom of the coating roller 3.

[0019] The arc scraper 14 is relatively arranged in the frame 4 and is located above the front side of the coating roller 3. In the present embodiment, the cross-section of the arc scraper 14 is a semicircular ring structure. The length of the arc scraper 14 corresponds to the length of the coating roller 3. The convex arc surface of the arc scraper 14 is in elastic contact with both sides of the carrier cloth 5 to remove excess waterproof asphalt and improve the coating uniformity.

[0020] like Figure 1 As shown, the frame 4 is provided with a baffle plate 15 located on the outer side of the back of the arc scraper 14, and the back of the arc scraper 14 is provided with a screw rod 16 penetrating the baffle plate 15 at intervals to guide the lateral movement of the arc scraper 14. The screw rod 16 is provided with a nut 17 located between the arc scraper and the baffle plate, and the screw rod 16 is provided with a spring 7 located between the nut 17 and the baffle plate 15 for elastic support, and the nut 17 is used to adjust the elastic support force, thereby adjusting the coating thickness.

[0021] The wind knife 8 is arranged in the frame 4 and is located above the arc scraper 14. In the present embodiment, the air outlet of the wind knife 8 points downward to the arc scraper 14. The wind knife 8 is used to blow air to the upper part of the arc scraper 14, which can not only avoid the waterproof asphalt from being retained in the upper part of the arc scraper 14, but also is beneficial to the cooling of the waterproof asphalt on both sides of the carrier cloth 5, thereby reducing the fluidity and sliding problems.

[0022] The wind box 11 is relatively arranged on the frame 4 and above the wind knife 8. An air distribution plate 13 is arranged on the front of the wind box 11. In this embodiment, an air supply pipe joint 12 is arranged on the back of the wind box 11, which is connected to an external compressed air pipeline to inflate the wind box 11. The air distribution plate 13 is provided with air outlet holes in a rectangular array to evenly send the air flow to the carrier cloth 5 between the air distribution plates 13 on both sides, which can not only improve the cooling effect of the waterproof asphalt on the carrier cloth 5, but also prevent the waterproof asphalt from slipping.

[0023] A roller support 10 extending to the top of the bellows 11 is relatively arranged on the frame 4, and the second guide roller 9 is arranged on the top of the roller support 10 to guide the carrier cloth 5 vertically upward. The carrier cloth 5 enters the oiling box 2 through the first guide roller 6, passes through the bottom of the coating roller 3, and is vertically sent upward between the two second guide rollers 9. In this embodiment, the bellows 11 are located on both sides of the path of the carrier cloth, and the arc scraper 14 is located on both sides of the path of the carrier cloth, first removing the excess waterproof asphalt on both sides of the carrier cloth, and then cooling it.

[0024] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
