Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically a scraper structure for a wall panel cold glue coating machine. Background Technology

[0002] A coating machine is a composite device that attaches decorative materials to the surface of profiles or powders. In the process of coating wall panels, hinges need to be coated on the outside of the wall panel. In order to ensure the uniformity of the adhesive coating, a scraper is needed to scrape off and level the coated adhesive to ensure the uniformity of the adhesive coating.

[0003] In the process of cold adhesive coating of wall panels, the scraper is used to scrape and level the adhesive applied to the outside of the wall to ensure the uniformity of the adhesive coating. However, during the transportation of wall panels, the use of conveyor belts or rollers for transport causes vibration when the drive device moves the wall panels. This vibration causes the distance between the wall panel and the scraper to change when the wall panel moves to the lower end of the scraper, resulting in unevenness in the leveling area. Therefore, we propose a scraper structure for a wall panel cold adhesive coating machine. Utility Model Content

[0004] To address the shortcomings of existing scraper structures used in wall panel cold glue coating machines, this invention provides a scraper structure for such machines. This structure allows the scraper to move to the upper end of the wall panel, and then adjusts the position of the slider inside the horizontal plate, i.e., the roller moves to the side of the wall panel. The roller presses and limits the position of the side of the wall panel, improving the balance of the distance between the scraping area and the scraper during transport. This enhances the accuracy of scraping and leveling, solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a scraper structure for a wall panel cold glue coating machine, including a conveyor box, with brackets fixedly connected to both sides of the conveyor box, a first lead screw movably sleeved inside the brackets, a connecting plate threaded onto the outside of the first lead screw, a horizontal plate fixedly connected to the lower end of the connecting plate, an inclined plate mounted on one side of the horizontal plate via a hinge, a scraper mounting seat mounted on the front end of the inclined plate via a sliding device, a limit sleeve and a limit pin fixed on both sides of the scraper mounting seat, a scraper mounted on the lower part of the front end of the scraper mounting seat via a clamping device, a second lead screw movably sleeved inside the horizontal plate, and a slider threaded onto the outside of the second lead screw.

[0006] Preferably, the clamping device includes a limiting plate, which is fixed on both sides of the scraper. A buckle is installed on the inner side of the limiting plate by a first spring. The buckle is movably sleeved on the outside of the limiting pin, and the limiting sleeve is movably sleeved on the outside of both sides of the scraper.

[0007] Preferably, the scraper has a groove inside, and a fastening bolt is installed inside the groove. One end of the fastening bolt is fixedly connected to an auxiliary scraper.

[0008] Preferably, a sliding sleeve is fixedly connected to the outside of the inclined plate, and a sliding plate is movably sleeved inside the sliding sleeve, with the sliding plate fixed to the rear end of the scraper mounting base.

[0009] Preferably, the rear ends of the horizontal plate and the inclined plate are equipped with telescopic rods, and the connecting plate is vertically installed at the upper end of the wall panel.

[0010] Preferably, one end of the slider is mounted with a roller bracket via a second spring, the lower end of the roller bracket is obliquely movably sleeved with a roller, and the second lead screw passes through the interior of the roller bracket.

[0011] Preferably, the conveyor box is equipped with rollers inside, a wall panel is placed on top of the rollers, the rollers are mounted on the side of the wall panel, and a scraper is set at the top of the wall panel.

[0012] Compared with the scraper structure of existing wall panel cold glue coating machines, this utility model has the following advantages:

[0013] 1. The wall panel cold glue coating machine uses a scraper structure. The scraper is installed at the front end of the scraper mounting base. The limiting sleeve limits the position of the scraper, and the first spring pushes the buckle to engage inside the scraper. This improves the flexibility of the scraper when it is installed at the front end of the scraper mounting base. The telescopic rod is activated to adjust the angle of the scraper and adjust the position of the sliding plate inside the sliding sleeve. This means that the distance between the scraper and the wall panel can be adjusted, improving the accuracy of the scraper in controlling the thickness of the glue.

[0014] 2. This wall panel cold glue coating machine uses a scraper structure. By rotating the second lead screw, the position of the slider inside the horizontal plate is adjusted. Depending on the thickness of the wall panel, the roller can be driven to clamp the side of the wall panel. At the same time, the scraper smooths the glue coating on the outside of the wall panel. The roller ensures that the distance between the wall panel and the scraper is adjusted to avoid vibration during the transportation of the wall panel, which would cause the distance between the scraper and the wall panel to deviate and result in uneven glue coating when scraping off the glue.

[0021] 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.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A scraper structure for a wall panel cold glue coating machine includes a conveyor box 1. Supports 4 are fixedly connected to both sides of the conveyor box 1. A first lead screw 5 is movably sleeved inside the support 4. Rotating the first lead screw 5 causes threaded movement between the first lead screw 5 and a connecting plate 6, adjusting the height of the scraper 15. The connecting plate 6 is threaded onto the outside of the first lead screw 5. A horizontal plate 7 is fixedly connected to the lower end of the connecting plate 6. The position of the horizontal plate 7 is adjusted, and the position of the horizontal plate 7 relative to an inclined plate 8 is also adjusted. An inclined plate 8 is hinged to one side of the horizontal plate 7. Activating a telescopic rod 9 adjusts the angle of the inclined plate 8, increasing the tilt angle of the inclined plate 8 relative to the horizontal plate 7. The adjustment is as follows: a scraper mounting seat 12 is installed at the front end of the inclined plate 8 via a sliding device. A limit sleeve 13 and a limit pin 14 are fixed on both sides of the scraper mounting seat 12 respectively. The limit sleeve 13 and the limit pin 14 are interlocked with the clamping device to ensure that the scraper 15 is limited to the side of the scraper mounting seat 12. The scraper 15 is installed at the lower part of the front end of the scraper mounting seat 12 via the clamping device. A second lead screw 21 is movably sleeved inside the horizontal plate 7. A slider 22 is threaded on the outside of the second lead screw 21. Rotating the slider 22 pushes the position of the roller 25 to move. The roller 25 is clamped on the side of the wall plate 3 to ensure that the wall plate 3 remains stable at the lower end of the scraper 15.

[0023] Please see Figure 5 The clamping device includes a limiting plate 16, which is fixed to both sides of the scraper 15. A buckle 18 is installed on the inner side of the limiting plate 16 via a first spring 17. The buckle 18 is movably sleeved on the outside of the limiting pin 14. The limiting sleeve 13 is movably sleeved on the outside of both sides of the scraper 15. The clamping device is installed on both sides of the scraper 15. When the scraper 15 is installed, the scraper 15 is attached to the outside of the scraper mounting base 12. At the same time, the limiting sleeve 13 is engaged with the outside of the scraper 15, which improves the stability of the scraper 15 when it is limited. The first spring 17 pushes the buckle 18 to move inward, and the buckle 18 is engaged with the outside of the limiting pin 14, which ensures that the scraper 15 is tightly and conveniently installed on the outside of the scraper mounting base 12.

[0024] Please see Figure 5 The scraper 15 has a groove inside, and a fastening bolt 19 is installed inside the groove. One end of the fastening bolt 19 is fixedly connected to an auxiliary scraper 20. By adjusting the position of the fastening bolt 19 through the groove on the inner side of the scraper 15, the fastening bolt 19 drives the auxiliary scraper 20 to adjust its position on both sides of the scraper 15, controlling the auxiliary scraper 20 to adhere to the side of the wall panel 3. During the process of applying adhesive to the outside of the wall panel 3, after the scraper scrapes the adhesive to both sides, the auxiliary scraper 20 cleans the adhesive contained on both sides of the wall panel 3 to prevent the adhesive from adhering to the side of the wall panel 3, which would affect the phenomenon of insufficient adhesive scraping.

[0025] Please see Figure 3 The inclined plate 8 is externally fixedly connected to a sliding sleeve 10, and a sliding plate 11 is movably sleeved inside the sliding sleeve 10. The sliding plate 11 is fixed to the rear end of the scraper mounting base 12. The sliding sleeve 10 and the sliding plate 11 are installed between the telescopic rod 9 and the scraper mounting base 12. By adjusting the position of the sliding plate 11 inside the sliding sleeve 10, the position of the scraper mounting base 12 at the front end of the inclined plate 8 is adjusted. The scraper mounting base 12 drives the distance between the scraper 15 and the wall panel 3 to be adjusted, thereby realizing the control of the scraping depth.

[0026] Please see Figure 3 The horizontal plate 7 and the inclined plate 8 are equipped with telescopic rods 9 at their rear ends. The connecting plate 6 is vertically installed on the upper end of the wall panel 3. By activating the telescopic rod 9, the angle between the inclined plate 8 and the wall panel 3 can be adjusted. In other words, the angle of the scraper 15 outside the wall panel 3 can be adjusted, which means that it can be precisely adjusted according to different scraping effects.

[0027] Please see Figure 4One end of the slider 22 is equipped with a roller bracket 24 via a second spring 23. The lower end of the roller bracket 24 is obliquely fitted with a roller 25. The second lead screw 21 passes through the interior of the roller bracket 24. Depending on the width of the wall panel 3, the second lead screw 21 is rotated, and the second lead screw 21 and the slider 22 perform threaded movement. That is, the slider 22 drives the roller bracket 24 to adjust its position inside the horizontal plate 7, and the second spring 23 pushes the roller bracket 24 to move inward, controlling the roller 25 to move to both sides of the wall panel 3. After the roller 25 is in contact with the side of the wall panel 3, the roller 25 limits the movement trajectory of the wall panel 3, ensuring that the position of the wall panel 3 does not shift during the scraping and leveling process of the scraper 15 on the outside of the wall panel 3, thus affecting the scraping efficiency of the scraper 15 on the adhesive.

[0028] Please see Figure 2 Inside the conveyor box 1, rollers 2 are installed. A wall panel 3 is placed on top of the rollers 2. Rollers 25 are installed on the side of the wall panel 3, and a scraper 15 is set at the top of the wall panel 3. The rollers 2 inside the conveyor box 1 push the wall panel 3 to move laterally. At the same time, an adhesive applicator is provided on the outside of the conveyor box 1. After the adhesive applicator applies adhesive to the top of the wall panel 3, the wall panel 3 moves to the bottom of the rollers 25. The angle of the scraper 15 is adjusted so that the scraper 15 is set at the top of the wall panel 3 and the rollers 25 move to the side of the wall panel 3. This ensures that the wall panel 3 remains stable during movement and prevents the position of the wall panel 3 from being affected by vibration and displacement during conveying, which would affect the effectiveness of the scraper.

[0029] Working principle: In use, the wall panel 3 is placed on the upper part of the roller 2. The roller 2 pushes the wall panel 3 to move. At the same time, the glue applicator coats the outside of the wall panel 3 with a layer of glue. The first lead screw 5 is activated, which drives the height of the connecting plate 6 to adjust. At the same time, the telescopic rod 9 is activated, which drives the tilt angle of the scraper mounting seat 12 to adjust. After adjusting the position of the sliding plate 11 inside the sliding sleeve 10, the distance between the scraper 15 and the wall panel 3 is adjusted. The roller 25 moves to the side of the wall panel 3. The second lead screw 21 is rotated, which pushes the position of the slider 22 to adjust. Under the elastic action of the second spring 23, the roller bracket 24 controls the roller 25 to press against the side of the wall panel 3, ensuring the stability of the scraper 15 and the wall panel 3 when positioned. When the wall panel 3 moves, the scraper 15 scrapes off the glue coating on the outside of the wall panel 3 to ensure the uniformity of the glue coating.
