[0003] In the existing process of rubber coating on the surface of PE short pipes, when glue is sprayed on the surface of the PE short pipe, due to the fluidity of the glue and the influence of gravity, the glue is likely to drop along the arc-shaped surface of the PE short pipe, thus easily generating flow marks on the surface of the PE short pipe, and easily resulting in the phenomenon of uneven rubber coating on its surface. Therefore, how to provide a rubber coating device that can level the glue sprayed on the surface of the PE short pipe is particularly important. In view of this, we propose a pipe outer ring rubber coating device for composite pipe processing. Summary of the Utility Model

[0025] As Figures 1 to 7 shown, a rubber coating device for the outer circle of a composite pipe used in the present utility model includes a horizontal frame 1. Chutes are arranged on both sides of the horizontal frame 1. A rubber coating assembly 2 is slidably connected in the chutes. The rubber coating assembly 2 includes a spraying unit 3 and a scraping unit 4. Limiting components 5 are arranged at both ends of the horizontal frame 1;

[0026] A PE pipe body is placed on the surface of the limiting component 5.

[0027] In an embodiment of the present utility model, the spraying unit 3 includes a connecting rod 301. The connecting rod 301 is slidably connected in the chute. The end of the connecting rod 301 is fixedly connected with a spraying cylinder 302. A cavity is formed in the spraying cylinder 302. Glue spraying heads 303 are annularly and equidistantly arranged on the inner wall of the cavity. The upper end surface of the spraying cylinder 302 is fixedly connected with a glue dispenser 304. The glue dispenser 304 is communicated with the glue spraying heads 303 through a pipeline.

[0028] In an embodiment of the present utility model, the spraying cylinder 302 is fixedly connected to the scraping unit 4 through a support rod. The scraping unit 4 includes a scraping frame 401 and a storage frame 402. The scraping frame 401 and the storage frame 402 are fixedly connected to each other and jointly define a scraping cavity 403. A scraping plate 404 is annularly arranged in the scraping frame 401. By providing the scraping plate 404, the excess glue generated on its surface can be timely scraped during the gluing process, which can prevent the excess glue from dripping due to gravity along the annular surface of the PE pipe body, improving the flatness of the surface gluing. The scraping plate 404 includes a bending portion 4041. A collecting plate 405 is annularly arranged in the storage frame 402. The collecting plate 405 includes a material guiding portion 4051. The material guiding portion 4051 is arranged on one side of the bending portion 4041. The material guiding portion 4051 and the bending portion 4041 form a storage cavity 406. By providing the storage cavity 406, the scraped glue can be collected and placed, which can prevent the glue scraped by the scraping plate 404 from piling up on the surface of the PE pipe body. A glue discharge hole is provided in the storage frame 402. By providing the glue discharge hole, the excess scraped glue can be discharged, preventing the inside of the scraping unit 4 from being blocked after scraping too much glue. The glue discharge hole can dredge the accumulated glue inside it.

[0029] As another embodiment of the present utility model, the limiting component 5 includes a limiting groove opened in the transverse frame 1. A spring 501 is fixedly connected to the inner wall of the limiting groove. A limiting rod 502 is sleeved on the surface of the spring 501. The end of the limiting rod 502 is fixedly connected to a support plate 503. A limiting column 504 is fixedly connected to one side of the support plate 503. The PE pipe body is sleeved on the surface of the limiting column 504. By providing the limiting component 5, when the spraying unit 3 places the PE pipe body, the PE pipe body can maintain the balance of its position during the spraying process, and the shaking of the position of the PE pipe body can be avoided, thereby preventing the unevenness of the surface gluing.

[0030] Working principle: This embodiment provides a rubber coating device for the outer circle of pipes used in the processing of composite pipes. When in use, first pull the support plate 503 on one side to squeeze the spring 501, so that the PE pipe body can be sleeved on the surface of the limit post 504. Then cancel the extrusion of the spring 501, and the reset of the spring 501 drives the position of the limit post 504 to be restored, so that the position of the PE pipe body is limited between the two support plates 503. Subsequently, the spraying unit 3 and the scraping unit 4 can be moved on the surface of the PE pipe body through the chute. At this time, start the glue dispenser 304, so that the glue can be sprayed on the surface of the PE pipe body through the glue spraying head 303. While the spraying unit 3 moves and coats the surface of the PE pipe body with glue, the scraping plate 404 can timely scrape off the glue overflowing on the surface of the PE pipe body. The scraped glue follows the curved surface of the bending part 4041 and is discharged to the storage cavity 406 through the glue guiding part 4051, and then can be discharged through the glue discharge hole.

Those of ordinary skill in the art can easily understand the spirit of this utility model according to the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of this utility model, they are within the protection scope of this utility model.
