Description

Technical Field

[0001] This utility model belongs to the technical field of automatic gluing machines, specifically relating to an automatic gluing machine for composite board processing. Background Technology

[0002] Composite panels are generally classified into: metal composite panels, wood composite panels, color steel composite panels, rock wool composite panels, etc. Composite panels are composed of different materials with different functions in layers. Therefore, during the production of composite panels, multiple layers of panels need to be bonded together with glue, so an automatic glue roller is required during the processing.

[0003] An automatic glue-coating machine for composite board processing, with authorization announcement number CN 222241086 U, includes two conveyor components forming a placement cavity for placing the board material. The conveyor components transport the board material along a preset path. It also includes two coating rollers rotating along a preset axis perpendicular to the preset path. Both coating rollers are mounted on one side of the preset path, with one side of each roller contacting the surface of the board material. Each conveyor component includes a mounting frame. This invention, by using two conveyor components, allows the board material to move between them when glue needs to be applied. During a single application, glue can be applied to both sides of the board simultaneously. Therefore, the operator does not need to wait for one side of the glue to dry before applying glue again, reducing the difficulty of glue application and improving the efficiency of the device.

[0004] The above application still has the following shortcomings in practical application:

[0005] Limited adhesive thickness adjustment: Traditional adhesive scraping mechanisms use fixed scrapers that can only scrape the adhesive on the outer side of the board, and the scraper position is not adjustable, resulting in the adhesive layer thickness being unable to adapt to different process requirements. For example, when processing composite boards of different thicknesses or materials, it is necessary to adjust the amount of adhesive applied to optimize the bonding effect, but existing equipment lacks a flexible adjustable mechanism, making it difficult to achieve precise control and affecting the consistency of product quality.

[0006] Adhesive is difficult to recycle: During operation, some adhesive remains on the coating rollers of existing roll coating machines because it is not completely absorbed by the board material. If it cannot be effectively recycled, it will result in adhesive waste and increase production costs. Although some equipment is equipped with a simple recycling tank, it lacks an active flow guidance design, making it difficult to recycle the adhesive and hindering efficient reuse. In summary, existing automatic roll coating machines have significant shortcomings in terms of adhesive thickness adjustment and adhesive recycling. There is an urgent need for an improved solution with an adjustable adhesive scraping mechanism and efficient adhesive recycling to improve coating accuracy, reduce waste, and enhance process adaptability for automatic roll coating machines used in composite board processing.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0008] The purpose of this invention is to provide an automatic glue-rolling machine for composite board processing, so as to solve the problems of limited glue thickness adjustment and low glue recycling efficiency in the prior art.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] An automatic glue-rolling machine for composite board processing includes a base. Two symmetrically arranged side plates are fixedly connected to the top of the base. A glue storage tank is fixedly connected between the tops of the two side plates. A feed hopper is fixedly connected to the feed inlet at the top of the glue storage tank. A pump body is fixedly connected to the bottom of the glue storage tank. An n-type flexible hose is connected to the discharge port of the pump body through a conveying pipe. Both ends of the n-type flexible hose extend to the inner side of a movable frame, and the free ends are located at the bottom and top of the coating rollers. The coating rollers are rotatably connected to the inner side of the movable frame. A conveyor belt is also driven to the inner side of the movable frame. Two symmetrically arranged electric telescopic rods are fixedly connected to one side wall opposite to the two side plates. The telescopic ends of the electric telescopic rods movably penetrate the side plates and are fixed to the back of the movable frame. An adjustable glue-scraping assembly is installed on the movable frame near the coating rollers. A receiving assembly installed on the base is located below the adjustable glue-scraping assembly.

[0011] Preferably, the receiving assembly includes a receiving box disposed below the two coating rollers. The receiving box is movably placed in a placement slot opened at the top of the base, and a hand-tightening screw is threaded onto one side wall of the base. The end of the hand-tightening screw, after being tightened, abuts against the outer side wall of the receiving box.

[0012] Preferably, each of the receiving boxes is provided with an inclined surface at the edge of the inner bottom wall of the movable frame.

[0013] Preferably, the adjustable coating assembly includes two symmetrically arranged guide rods that are movably inserted into the movable frame near the end of the coating roller. The vertical cross-section of both guide rods is convex, and the guide rods are slidably connected to a guide groove opened in the movable frame near the end of the coating roller.

[0014] Preferably, a hand-tightening screw is threaded between the two guide rods and connected to the movable frame. One end of the hand-tightening screw is rotatably connected to the back of the scraper, and the back of the scraper is also fixed to one end of the two guide rods. The other end of the hand-tightening screw is fixed with a handle.

[0015] Preferably, the cross-section of the scraper has a right-angled triangular structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The automatic glue roller for composite board processing of this utility model can be rotated by hand-tightening the screw when the position of the scraper needs to be adjusted. With the help of the guide rod, the scraper can move away from or towards the center of the top of the base, thereby adjusting the thickness of the glue scraped after the board is glued. The scraped glue and the glue that falls freely on the coating roller will slide down the inclined surface into the receiving box for collection, so that it can be recycled back into the glue storage box for use later. Compared with the prior art, it has an improved scheme of adjustable scraping mechanism and efficient glue recycling, which improves coating accuracy, reduces waste and enhances process adaptability. The effect is good. Attached Figure Description

[0025] The above application still has the following shortcomings in practical application:

[0026] Limited adhesive thickness adjustment: Traditional adhesive scraping mechanisms use a fixed scraper 42, which can only scrape the adhesive on the outer side of the board. Furthermore, the position of the scraper 42 is not adjustable, resulting in an adhesive layer thickness that cannot adapt to different process requirements. For example, when processing composite boards of different thicknesses or materials, it is necessary to adjust the amount of adhesive applied to optimize the bonding effect. However, existing equipment lacks a flexible, adjustable mechanism, making precise control difficult and affecting product quality consistency.

[0027] Adhesive is difficult to recycle: During operation, some adhesive remains on the coating roller 14 of existing roll coating machines because it is not completely absorbed by the board. If it cannot be effectively recycled, it will result in adhesive waste and increase production costs. Although some equipment is equipped with a simple recycling tank, it lacks an active flow guidance design, making it difficult to recycle the adhesive and unable to achieve efficient reuse. In summary, existing automatic roll coating machines have significant shortcomings in terms of adhesive thickness adjustment and adhesive recycling.

[0028] See attached document Figure 1-2 An automatic glue-rolling machine for composite board processing includes a base 1. Two symmetrically arranged side plates 11 are fixedly connected to the top of the base 1. A glue storage tank 2 is fixedly connected between the tops of the two side plates 11. A feed hopper 21 is fixedly connected to the feed inlet at the top of the glue storage tank 2. A pump body 22 is fixedly connected to the bottom of the glue storage tank 2. An n-type flexible hose 23 is connected to the outlet of the pump body 22 via a conveying pipe. Both ends of the n-type flexible hose 23 extend to the inner side of a moving frame 12, and their free ends are both located at the bottom and top of a coating roller 14. The cloth rollers 14 are rotatably connected to the inner side of the movable frame 12, and the inner side of the movable frame 12 is also connected to the conveyor belt 13. Two symmetrically arranged electric telescopic rods 16 are fixed on the side wall of the two side plates 11 facing away from each other. The telescopic ends of the electric telescopic rods 16 can move through the side plates 11 and are fixed to the back of the movable frame 12. An adjustable scraper assembly 4 is installed on the movable frame 12 near the end of the coating rollers 14. A receiving assembly installed on the base 1 is provided below the adjustable scraper assembly 4.

[0029] The automatic glue-rolling machine has the same main structure as the prior art application;

[0030] The conveyor belt 13 is driven by the motor 15, which is consistent with the structure of the prior art application.

[0031] Furthermore, such as Figure 1-2 As shown, in order to facilitate the glue on the coating roller 14 to fall onto the inner bottom wall of the movable frame 12 and flow freely into the receiving box 3, the receiving assembly includes a receiving box 3 located below the two coating rollers 14. The receiving box 3 is movably placed in the placement groove opened at the top of the base 1, and a hand screw 32 is threadedly connected to one side wall of the base 1. The end of the hand screw 32 after being tightened abuts against the outer side wall of the receiving box 3. The receiving box 3 is also provided with a slope 31 opened at the edge of the inner bottom wall of the movable frame 12.

[0032] Furthermore, such as Figure 1-2 As shown, in order to adjust the thickness of the adhesive on the surface of the board, an adjustable adhesive scraper assembly 4 is provided, including two symmetrically arranged guide rods 41 that are movably inserted into the movable frame 12 near the end of the coating roller 14. The vertical cross-section of the two guide rods 41 is convex. The guide rods 41 are slidably connected to the guide groove opened at the end of the movable frame 12 near the coating roller 14. A hand-tightening screw 43 is threadedly connected to the movable frame 12 between the two guide rods 41. One end of the hand-tightening screw 43 is rotatably connected to the back of the scraper 42. The back of the scraper 42 is also fixed to one end of the two guide rods 41. The other end of the hand-tightening screw 43 is fixed to a handle. The cross-section of the scraper 42 is a right-angled triangular structure.

[0033] The scraper 42 is made of elastic rubber.

[0034] In actual use, when the position of the scraper 42 needs to be adjusted, it can be rotated by hand-tightening the screw 43. With the help of the guide rod 41, the scraper 42 can move away from or towards the top center of the base 1, thereby adjusting the thickness of the glue scraped off after the board is coated. The scraped glue and the glue that falls freely on the coating roller 14 will slide down the inclined surface 31 into the receiving box 3 for collection, so that it can be recycled back into the glue storage box 2 for later use. Compared with the existing technology, it has an improved solution with an adjustable scraping mechanism and efficient glue recycling, which improves coating accuracy, reduces waste and enhances process adaptability, and has good performance.
