Description

Technical Field

[0001] This utility model relates to the field of bamboo-wound composite pipe outer protective layer production technology, specifically an automatic material application device for bamboo-wound composite pipe outer protective layer. Background Technology

[0002] In the utility model patent application CN214637573U, published on November 9, 2021, entitled "A Production Equipment for the Outer Protective Layer of Bamboo Winding Composite Pipe," this utility model discloses a production equipment for the outer protective layer of bamboo winding composite pipe, belonging to the field of bamboo winding composite pipe. It includes a winding die roller, the surface of which is provided with a scraping component for scraping adhesive onto its surface. The beneficial effects of this utility model are: in the prior art, the production of the outer protective layer involves directly spraying the outer protective layer onto the mold to be coated. Under the action of gravity, the adhesive is prone to uneven distribution, inconsistent thickness in different areas, and air bubbles are easily generated. Therefore, the scraping component allows the adhesive on the winding die roller to have a smoother and more even surface after scraping. Furthermore, the scraping component can fill in uneven areas, achieving an overall smooth and uniform outer protective layer, and also controlling the cured thickness of the outer protective layer.

[0003] In the prior art, including the aforementioned patents, during the coating process, paint particles may accumulate and dry near the spray nozzle, leading to blockage. Blockage of the spray nozzle requires manual cleaning or machine shutdown for maintenance, which interrupts the production process and reduces work efficiency. At the same time, blockage of the spray nozzle will cause uneven coating, affecting the uniformity and integrity of the outer protective layer of the bamboo-wound composite pipe, reducing the protective performance and aesthetics of the protective layer. Therefore, it is necessary to design an automatic coating device for the outer protective layer of bamboo-wound composite pipe that prevents blockage. Utility Model Content

[0004] The purpose of this invention is to provide an automatic material application device for the outer protective layer of bamboo-wound composite pipes, so as to solve the problem of uneven material application caused by clogging of the spray position as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic material application device for the outer protective layer of bamboo-wound composite pipe, comprising a base, a sliding seat mounted on the top of the base, a support component slidably mounted on the top of the sliding seat, a drive motor mounted on the outer wall of the base, the output shaft of the drive motor being fixedly connected to a transmission structure via a coupling, a support seat mounted on one side of the base, a scraper mounted on one side of the support seat, a limit component fixedly connected to the outer wall of the support seat, a spray tower disposed on one side of the base, a spray pipe mounted on the outer wall of the spray tower, a cleaning fan mounted on the top of the spray tower, a cleaning pipe mounted on the outer wall of the cleaning fan, a filter fixedly connected to one end of the cleaning pipe, and a waste recycling tank disposed on the back of the base.

[0006] Furthermore, the support component internally includes a movable base, a threaded rod, a rocker arm, an adjusting frame, rollers, and a limiter. The movable base is slidably connected to the outer wall of the sliding seat. The threaded rod is movably connected to the interior of the movable base. One end of the threaded rod is fixedly connected to a rocker arm. A limiter is installed on the outer wall of the movable base. An adjusting frame is threadedly connected to the outer wall of the threaded rod. Rollers are provided on the top of the adjusting frame.

[0007] Furthermore, a tube is provided above the roller, and the support component and the limiting component are located at both ends of the tube.

[0008] Furthermore, the limiting assembly includes a rotating seat, a support shaft, an electric telescopic rod, a connecting shaft, and a limiting arc plate. The rotating seat is movably connected to the inside of the support seat, and the support shaft is slidably connected to the inside of the rotating seat. The electric telescopic rod is installed on the outer wall of the support shaft, and the output end of the electric telescopic rod is fixedly connected to the connecting shaft. The output end of the connecting shaft is movably connected to the limiting arc plate.

[0009] Furthermore, the rotating seat rotates along the interior of the support seat, and the limiting arc plates are symmetrical about each other along the rotating seat.

[0010] Furthermore, the limiting component is located inside the tube body, and the limiting arc plate is in close contact with the tube body. The outer walls of both the rotating seat and the limiting arc plate are provided with sliding grooves.

[0011] Furthermore, the scraper is in contact with the outer wall of the pipe, the bottom of the spray pipe is provided with a nozzle, and the nozzle angle is inclined towards the pipe. The transmission structure consists of a drive wheel, a belt and a driven wheel.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the automatic coating device for the outer protective layer of bamboo-wound composite pipe is reasonable and has the following advantages:

[0013] By continuously blowing the circulating air of the cleaning fan through the spray pipe, the inside of the pipe is cleaned, and air circulation is maintained around the spray nozzles. This reduces the possibility of paint particles adhering and drying, effectively preventing the spray nozzles from being blocked. This ensures the normal operation of the spraying device and a stable spraying effect. At the same time, using the circulating air of the cleaning fan for anti-clogging treatment can reduce downtime and maintenance workload caused by spray nozzle blockage. This allows the spraying operation of the outer protective layer of bamboo-wound composite pipes to be carried out continuously and efficiently, improving overall production efficiency. It can ensure that the paint is sprayed evenly on the outer surface of the composite pipe, thereby ensuring the quality stability of the protective layer and improving the protective effect and service life of bamboo-wound composite pipes. In addition, after cleaning with air power, the air adsorption will dry the cured coating adhesive, which is then collected and treated by a filter.

[0014] The design incorporates support and limiting components to facilitate the support and positioning of the composite pipe. The built-in limiting components accurately define the position of the bamboo-wound composite pipe, ensuring the pipe remains in a fixed position during the coating process. This allows the coating device to precisely and evenly spray the protective material onto the outer surface of the pipe, helping to ensure the uniformity and integrity of the protective layer thickness and improving the protective effect. The device can be adjusted according to different specifications and sizes of bamboo-wound composite pipes. Using the sliding seat support, the support distance can be changed according to the length. During the continuous winding of bamboo fibers, a rocker arm can be used to rotate the threaded rod, thereby changing the position of the adjusting frame and adjusting it according to the winding thickness. The support distance can also be changed according to the length. Furthermore, the electric telescopic rod, in conjunction with the support shaft and connecting shaft, can provide limiting support based on the inner diameter of the pipe. By changing the parameters of the limiting structure or adopting an adjustable design, it can adapt to the support needs of pipes with various diameters, lengths, and shapes, improving the versatility and flexibility of the automatic coating device and reducing equipment replacement and adjustment costs.

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.

[0022] Please see Figure 1-5 The present invention provides a technical solution as follows: Example

[0023] An automatic material application device for the outer protective layer of bamboo-wound composite pipe includes a base 1, a sliding seat 2 mounted on the top of the base 1, a support component 3 slidably mounted on the top of the sliding seat 2, a drive motor 4 mounted on the outer wall of the base 1, a transmission structure 5 fixedly connected to the output shaft of the drive motor 4 via a coupling, a support seat 6 mounted on one side of the base 1, a scraper 7 mounted on one side of the support seat 6, a limit component 8 fixedly connected to the outer wall of the support seat 6, a spray tower 9 set on one side of the base 1, a spray pipe 10 mounted on the outer wall of the spray tower 9, a cleaning fan 11 mounted on the top of the spray tower 9, a cleaning pipe 12 mounted on the outer wall of the cleaning fan 11, a filter 13 fixedly connected to one end of the cleaning pipe 12, and a waste recycling tank 14 set on the back of the base 1.

[0024] The above structure uses the circulating air from the cleaning fan 11 to continuously blow air through the spray pipe 10, cleaning the inside of the pipe and keeping the air around the spray nozzles circulating. This reduces the possibility of paint particles adhering and drying, thereby effectively preventing the spray nozzles from being blocked and ensuring the normal operation of the spraying device and a stable spraying effect.

[0025] Furthermore, the support component 3 includes a movable base 301, a threaded rod 302, a rocker arm 303, an adjusting frame 304, a roller 305, and a limiter 306. The movable base 301 is slidably connected to the outer wall of the sliding seat 2. The threaded rod 302 is movably connected inside the movable base 301. One end of the threaded rod 302 is fixedly connected to the rocker arm 303. The limiter 306 is installed on the outer wall of the movable base 301. The adjusting frame 304 is threadedly connected to the outer wall of the threaded rod 302. The roller 305 is provided on the top of the adjusting frame 304. The tube body 15 is provided above the roller 305. The support component 3 and the limiter component 8 are located at both ends of the tube body 15.

[0026] The above structure is supported by the sliding seat 2, and the support distance can be changed according to the length.

[0027] Furthermore, the limiting component 8 includes a rotating seat 801, a support shaft 802, an electric telescopic rod 803, a connecting shaft 804, and a limiting arc plate 805. The rotating seat 801 is movably connected inside the support seat 6, and the support shaft 802 is slidably connected inside the rotating seat 801. The electric telescopic rod 803 is installed on the outer wall of the support shaft 802. The output end of the electric telescopic rod 803 is fixedly connected to the connecting shaft 804, and the output end of the connecting shaft 804 is movably connected to the limiting arc plate 805. The rotating seat 801 rotates along the inside of the support seat 6, and the limiting arc plates 805 are symmetrical about the rotating seat 801. The limiting component 8 is located inside the tube body 15, and the limiting arc plate 805 fits against the tube body 15. The outer walls of both the rotating seat 801 and the limiting arc plate 805 are provided with grooves.

[0028] The above structure uses an electric telescopic rod 803 in conjunction with a support shaft 802 and a connecting shaft 804 to provide limiting support according to the inner diameter of the tube body 15.

[0029] Furthermore, the scraper 7 is in contact with the outer wall of the pipe body 15, the bottom of the spray pipe 10 is provided with a nozzle, and the nozzle angle is inclined towards the pipe body 15. The transmission structure 5 consists of a drive wheel, a belt and a driven wheel.

[0030] The above structure uses a scraper 7 to smooth the adhesive sprayed on the surface, making the application more even.

[0031] Working principle: In use, firstly, according to the required production length, the inner pipe of the bamboo-wound composite pipe is fixed above the support component 3. The limiting component 8 is inserted into the inside of the pipe body 15 for adjustment. Through the cooperation of the designed support component 3 and the limiting component 8, the built-in limiting component 8 can accurately limit the position of the bamboo-wound composite pipe, ensuring that the pipe is in a fixed position during the material spraying process. This allows the material spraying device to accurately and evenly spray the protective material onto the outer surface of the pipe, which helps to ensure the uniformity and integrity of the protective layer thickness and improve the protective effect. At the same time, it can be adjusted according to bamboo-wound composite pipes of different specifications and sizes.

[0032] Secondly, by utilizing the support of the sliding seat 2, the support distance can be changed according to the length. During the continuous winding of bamboo fiber, the rocker arm 303 can be used to rotate the threaded rod 302, thereby changing the position of the adjusting frame 304 and adjusting it according to the winding thickness. At the same time, by using the electric telescopic rod 803 in cooperation with the support shaft 802 and the connecting shaft 804, the limit support can be provided according to the inner diameter of the tube body 15. By changing the parameters of the limit structure or adopting an adjustable design, it can adapt to the support requirements of various pipe diameters, lengths and shapes, improving the versatility and flexibility of the automatic material spreading device and reducing the replacement and adjustment costs of the equipment.

[0033] Finally, the circulating air from the cleaning fan 11 continuously blows through the spray pipe 10, cleaning the inside of the pipe and maintaining airflow around the spray nozzles. This reduces the possibility of paint particles adhering and drying, effectively preventing the spray nozzles from becoming clogged and ensuring the normal operation and stable spraying effect of the spraying device. At the same time, the use of circulating air from the cleaning fan 11 for anti-clogging treatment can reduce downtime and maintenance workload caused by spray nozzle blockage. The filter 13 is used to collect the dried adhesive, reducing solid blockage. Meanwhile, a waste recycling tank 14 is provided on the rear side of the base 1. After being connected by a pipe, excess paint can be recycled and collected.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
