Description

Technical Field

[0001] This utility model relates to the field of automated film application technology for concrete pipes, specifically an automated film application device for concrete pipes. Background Technology

[0002] Concrete formwork refers to the phenomenon where the surface of concrete adheres tightly to the formwork during the pouring, vibration, and initial setting stages. This phenomenon is affected by various factors such as the formwork material, surface smoothness, release agent usage, concrete mix proportions, and slump. A good formwork effect can make the concrete surface smooth and flat, reduce defects such as honeycomb and pitting, and improve the appearance quality. If the formwork is not applied well, it may lead to a rough concrete surface and sticking to the formwork, increasing the difficulty and cost of later processing. Therefore, properly controlling the degree of concrete formwork is an important step in ensuring the quality and aesthetics of concrete structures.

[0003] In the practical application of existing concrete pipe film-applying devices, the film-applying process has significant defects. Due to limitations in device design and operation, it is difficult to achieve a tight and uniform adhesion when applying the film to the surface of the concrete pipe. The film and the pipe cannot fit perfectly, which easily leads to wrinkles during the application process, damaging the flatness of the film. At the same time, air bubbles frequently appear. These air bubbles not only affect the appearance quality but may also reduce the protective effect of the film on the concrete pipe. The wrinkles and air bubbles seriously affect the overall quality of the concrete pipe film application, greatly reducing the film-applying effect and failing to meet the requirements of high-quality production. Therefore, we need an automated concrete pipe film-applying device. Utility Model Content

Simultaneously, the motor-driven spray head continuously rotates during the spraying process, ensuring uniform application of the release oil. Furthermore, the sliding sleeve along the rail can change the spraying position to meet the spraying needs of concrete pipes of different lengths, effectively improving spraying efficiency and quality.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model embodiment provides an automated film-applying device for concrete pipes, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the system includes a concrete pipe 1, a film-applying assembly 2 on one side of the concrete pipe 1, a spraying assembly 3 on another side of the concrete pipe 1, a slide rail 4 slidably connected to the bottom of the spraying assembly 3, a film-applying assembly 2 including a film supply roll 201, which is located at one end of the concrete pipe 1, a conveying roller 202 on one side of the film supply roll 201, a clamping roller 203 at the other end of the concrete pipe 1, a fixing frame 204 on one side of the concrete pipe 1, and a first cylinder 205 fixedly connected to the top of the fixing frame 204. One end of the first cylinder 205... A connecting plate 206 is fixedly connected. A slider 207 is fixedly connected to one side of the connecting plate 206. A slide rod 208 is slidably connected to the inner wall of the slider 207. A first motor 209 is fixedly connected to one side of the connecting plate 206. A threaded rod 210 is fixedly connected to the output shaft of the first motor 209 through a coupling. A threaded sleeve 211 is threadedly connected to the outer wall of the threaded rod 210. A first rack 212 is fixedly connected to one side of the threaded sleeve 211. A first gear 213 is meshed with one side of the first rack 212. A first gear 213 is fixedly connected to the inner wall of the first gear 213. A fixed rod 214 has a pressure roller 215 fixedly connected to its outer wall. By activating the film supply roll 201, PVC film is fed in conjunction with the conveyor roller 202. The PVC film is clamped by the conveyor roller 202 and the clamping roller 203. Activating the first cylinder 205 causes it to push the connecting plate 206 to move, which in turn moves the slider 207. The slider 207 slides along the outer wall of the sliding rod 208, allowing the connecting plate 206 to move the pressure roller 215 onto the concrete surface via a linkage mechanism. Inside the pipe 1, the first motor 209 is started simultaneously, which drives the threaded rod 210 to rotate. The threaded rod 210 passes through the threaded sleeve 211 and drives the threaded sleeve 211 to push it. The threaded sleeve 211 drives the first rack 212 to move. The first rack 212 drives the first gear 213 to rotate. The first gear 213 drives the fixed rod 214 to rotate, which in turn causes the pressure roller 215 to rotate and move along the inner wall of the concrete pipe 1, thereby achieving the pressing and bonding of the PVC film to the inner wall of the concrete pipe 1.

[0018] Furthermore, such as Figure 3 As shown, the first motor 209 forms a threaded structure with the threaded rod 210 and the threaded sleeve 211. One end of the threaded rod 210 is threaded through the threaded sleeve 211 and connected, and the other end of the threaded rod 210 is connected to the output end of the first motor 209. The first motor 209 can drive the threaded rod 210 to rotate and push the threaded sleeve 211 through the threaded sleeve 211.

[0019] Furthermore, such as Figure 3As shown, the connecting plate 206 forms a sliding structure with the slider 207 and the slide rod 208. The outer diameter of the slide rod 208 matches the inner diameter of the slider 207, and the outer wall of the slide rod 208 is fitted to the inner wall of the slider 207. Through the connecting plate 206, the connecting plate 206 can drive the slider 207 to move, and the slider 207 can slide along the outer wall of the slide rod 208.

[0020] Furthermore, such as Figure 3 and Figure 4 As shown, the first rack 212 forms a rotating structure with the first gear 213 and the fixed rod 214. One side of the first rack 212 meshes with one side of the first gear 213. The outer diameter of the fixed rod 214 matches the inner diameter of the first gear 213. The outer wall of the fixed rod 214 fits against the inner wall of the first gear 213. The first rack 212 can drive the first gear 213 to rotate, which in turn drives the fixed rod 214 to rotate.

[0021] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 5 and Figure 6As shown, the spray assembly 3 includes a sliding sleeve 301, which is fixed to the outer wall of the slide rail 4. A support rod 302 is fixedly connected to the top of the sliding sleeve 301. A movable frame 303 is slidably connected to the outer wall of the support rod 302. A second cylinder 304 is fixedly connected to one side of the support rod 302. A second motor 305 is fixedly connected to one side of the movable frame 303. The output shaft of the second motor 305 is fixedly connected to a lead screw 306 through a coupling. A threaded connecting sleeve 307 is threadedly connected to the outer wall of the lead screw 306. A second rack 308 is fixedly connected to the bottom of the threaded connecting sleeve 307. A second gear 309 is meshed with one side of the second rack 308. A conduit 310 is fixedly connected inside the second gear 309. A spray head 311 is fixedly connected to the outer wall of the conduit 310. A connecting pipe 312 is fixedly connected to the outer wall of the conduit 310. First, the concrete pipe 1 is horizontally clamped to the operating position. Then, the second cylinder 304 is activated to push the movable frame 303 to move, allowing the movable frame 303 to slide along the support rod 302. This adjusts the height of the movable frame 303, pulling the movable frame 303 moves the sliding sleeve 301, allowing the sliding sleeve 301 to slide along the slide rail 4, causing the spray assembly 3 to slide above the concrete pipe 1. Adjusting the height of the movable frame 303 back brings the spray head 311 close to the inner wall of the concrete pipe 1. Starting the second motor 305 causes the lead screw 306 to rotate, allowing the lead screw 306 to pass through the threaded connecting sleeve 307 and push the threaded connecting sleeve 307, thus allowing the threaded connecting sleeve... 307 drives the second rack 308 to move, which in turn drives the second gear 309 to rotate. The second gear 309 then drives the conduit 310 to rotate, causing the spray head 311 on the conduit 310 to rotate as well. The release oil is then delivered to the conduit 310 through the connecting pipe 312, and subsequently sprayed evenly onto the inner wall of the concrete pipe 1 through the spray head 311. At the same time, the sliding sleeve 301 continues to slide on the slide rail 4, which can change the spraying position to meet the spraying requirements.

[0022] Furthermore, such as Figure 6 As shown, the second motor 305 forms a threaded structure with the lead screw 306 and the threaded connecting sleeve 307. One end of the lead screw 306 is threaded through the threaded connecting sleeve 307 and connected, and the other end of the lead screw 306 is connected to the output end of the second motor 305. The second motor 305 can drive the lead screw 306 to rotate and push the threaded connecting sleeve 307 through it.

[0023] Furthermore, such as Figure 6As shown, the second gear 309 forms a rotating structure with the spray head 311 through the conduit 310, and the outer wall of the conduit 310 is connected to the inner wall of the spray head 311. One end of the conduit 310 is connected to the inside of the second gear 309. Through the second gear 309, the second gear 309 can drive the conduit 310 to rotate, and the conduit 310 can drive the spray head 311 to rotate.

[0024] Furthermore, such as Figure 6 As shown, there are multiple spray heads 311, and the multiple spray heads 311 are evenly spaced on the outer wall of the conduit 310, which allows multiple spray heads 311 to spray release oil onto the inner wall of the concrete pipe 1 at the same time, making the spraying of release oil inside the concrete pipe 1 more uniform.

[0025] Working principle: First, the concrete pipe 1 is horizontally clamped into the operating position. The second cylinder 304 is activated to move the movable frame 303, allowing it to slide along the support rod 302, thus adjusting its height. Pulling the movable frame 303 moves the sliding sleeve 301, allowing it to slide along the slide rail 4, causing the spray assembly 3 to slide above the concrete pipe 1. The height of the movable frame 303 is then adjusted back so that the spray head 311 approaches the inner wall of the concrete pipe 1. The second motor 305 is then activated, causing the lead screw 306 to rotate. The movement of the screw 306 through the threaded connecting sleeve 307 causes the threaded connecting sleeve 307 to move, which in turn causes the threaded connecting sleeve 307 to move the second rack 308, which in turn causes the second rack 308 to rotate the second gear 309, which in turn causes the conduit 310 to rotate. This causes the spray head 311 on the conduit 310 to rotate accordingly, delivering release oil to the conduit 310 through the connecting pipe 312. Subsequently, the release oil is sprayed evenly onto the inner wall of the concrete pipe 1 through the spray head 311. At the same time, the sliding sleeve 301 continues to move on the slide rail 4. The sliding mechanism allows for adjustments to the spray position to meet spraying requirements. After spraying is complete, the movable frame 303 is pulled back to move away from the concrete pipe 1. The film supply roll 201 is activated, cooperating with the conveyor roller 202 to begin conveying the PVC film. The PVC film is clamped by the conveyor roller 202 and the clamping roller 203. Activating the first cylinder 205 moves the connecting plate 206, which in turn moves the slider 207. The slider 207 slides along the outer wall of the sliding rod 208, allowing the connecting plate 206 to drive the pressure roller 21 via a linkage mechanism. 5. Move to the inside of the concrete pipe 1 and start the first motor 209. The first motor 209 drives the threaded rod 210 to rotate. The threaded rod 210 passes through the threaded sleeve 211 and drives the threaded sleeve 211 to push. The threaded sleeve 211 drives the first rack 212 to move. The first rack 212 drives the first gear 213 to rotate. The first gear 213 drives the fixed rod 214 to rotate. This causes the pressure roller 215 to rotate and move along the inner wall of the concrete pipe 1, thereby achieving the pressing and bonding of the PVC film to the inner wall of the concrete pipe 1.
