Description

Technical Field

[0001] This utility model relates to the field of adhesive coating technology, specifically to an adhesive coating device for the production of thick PE fiber composite boards. Background Technology

[0002] In the production process of thick PE fiber composite boards, gluing is a key step to ensure the composite quality of the boards. Existing gluing equipment has significant shortcomings when operating on thick PE fiber composite boards.

[0003] Traditional equipment has poor flexibility in adjusting the height of the gluing components, making it difficult to adapt to thick boards of different thicknesses. This often results in uneven gluing, missed areas, or glue accumulation due to mismatched spacing. At the same time, some equipment lacks a stable elastic support structure, which can cause slight shaking during board transportation, leading to unstable adhesion between the gluing components and the board surface. This further affects the gluing accuracy and seriously restricts the production quality and efficiency of thick PE fiber composite boards. Utility Model Content

[0020] 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.

[0021] Example

[0022] Please see Figure 1-5 This utility model provides a technical solution: a gluing device for producing thick PE fiber composite boards, comprising: a conveyor 1, with a gluing device 2 fixedly connected to the outer wall of the top of the conveyor 1; the gluing device 2 includes a support frame 21, with a threaded rod 22 threadedly connected to the inner wall of the top of the support frame 21, an adjusting plate 23 rotatably connected to the outer wall of the bottom of the threaded rod 22, a scraper 24 fixedly connected to the outer wall of the bottom of the adjusting plate 23, a glue storage box 25 provided below the adjusting plate 23, and a sliding rod 26 and a compression spring 27 symmetrically fixedly connected to the outer wall of the top of the glue storage box 25.

[0023] The outer wall of the side of the adjusting plate 23 is slidably connected to the inner wall of the side of the support frame 21. The compression spring 27 is set outside the slide rod 26. The outer wall of the slide rod 26 is slidably connected to the inner wall of the bottom of the adjusting plate 23. The outer wall of the side of the compression spring 27 away from the glue storage box 25 is fixedly connected to the outer wall of the bottom of the adjusting plate 23. The compression spring 27 is sleeved on the outside of the slide rod 26, and its two ends are respectively connected to the top of the glue storage box 25 and the bottom of the adjusting plate 23, providing elastic support for the adjusting plate 23 and ensuring that the glue scraper 24 is stably attached to the surface of the board.

[0024] A filling tube 28 is fixedly connected to the outer wall of the side of the glue storage box 25, and a glue conveying tube 29 is fixedly connected to the inner wall of the bottom of the glue storage box 25. A ball bearing 291 is rotatably connected to the inner wall of the bottom of the glue conveying tube 29, and a groove 292 is provided on the outer wall of the ball bearing 291.

[0025] The glue delivery tube 29 is arranged horizontally along the inner wall of the bottom of the glue storage box 25. The grooves 292 are arranged in a ring around the center point of the ball bearing 291. The glue flows through the glue delivery tube 29 to the ball bearing 291 at the bottom. The ball bearing 291 contacts the surface of the conveyed plate and rotates as the plate moves. The glue is evenly adhered to the ball bearing 291 through the grooves 292 arranged in a ring on the surface of the ball bearing 291. Then, the rotating ball bearing 291 transfers the glue to the surface of the plate.

[0026] When in use, the thick PE fiber composite board is placed on the conveyor 1 and continuously passes under the glue applicator 2. The glue applicator 2 has an adjustable height to accommodate PE fiber composite boards of different thicknesses.

[0027] First, the rotating threaded rod 22 drives the adjusting plate 23, which is rotatably connected at the bottom, to slide up and down along the inner side wall of the support frame 21, thereby adjusting the distance between the scraper 24 and the surface of the board to adapt to the glue application requirements of boards of different thicknesses. The compression spring 27 is sleeved on the outside of the slide rod 26, with its two ends connected to the top of the glue storage box 25 and the bottom of the adjusting plate 23, respectively, to provide elastic support for the adjusting plate 23 and ensure that the scraper 24 and the surface of the board remain stably attached.

[0028] After the conveyor 1 starts, it smoothly conveys the thick PE fiber composite board forward, allowing it to continuously pass under the glue coating device 2, providing a continuous working carrier for subsequent glue coating. Sufficient glue is injected into the glue storage box 25 in advance through the injection pipe 28. The glue is stored in the glue storage box 25 and flows naturally to the glue delivery pipe 29 at the bottom, completing the glue supply preparation before glue coating.

[0029] The glue delivery tubes 29 at the bottom of the glue storage box 25 are arranged horizontally. The glue flows through the glue delivery tubes 29 to the ball bearings 291 at the bottom. The ball bearings 291 contact the surface of the conveyed board and rotate as the board moves. The glue is evenly adhered to the ball bearings 291 through the grooves 292 in the annular array on the surface of the ball bearings 291. The rotating ball bearings 291 then transfer the glue to the surface of the board, completing the initial glue application. After the initial glue application, the board continues to move, and the glue scraper 24 scrapes the glue on the surface of the board to eliminate glue accumulation and ensure that the glue layer thickness is uniform.
