Description

Technical Field

[0001] This utility model relates to the technical field of film lamination equipment, and in particular to a fireproof board surface film lamination machine. Background Technology

[0002] Fireproof boards are a common building decoration material. In order to improve the aesthetics, wear resistance and service life of fireproof boards, it is necessary to coat the surface of the fireproof board with a film. The surface coating laminating machine is the key equipment to realize this process. Its main function is to flatly and firmly stick the decorative film onto the surface of the fireproof board.

[0003] In existing lamination technologies, a common method is to use heated rollers to heat-press the film onto the fireproof board. However, during the process of unwinding the film from the roller and conveying it to the lamination area, slight relaxation or wrinkles may occur due to tension changes or electrostatic adsorption. If these wrinkles are not treated and are directly pressed by the heated rollers in the subsequent hot pressing process, the high temperature and pressure will permanently fix these wrinkles to the surface of the board, seriously affecting the aesthetics and pass rate of the product.

[0004] To ensure a strong bond, the laminating machine needs to apply sufficient and uniform pressure to the fireproof board. Existing equipment either uses springs to provide elastic pressure or uses weights to provide constant pressure. However, as a rigid material, fireproof board inevitably has slight thickness tolerances during the production process. If only springs are used, the pressure will fluctuate greatly when faced with the impact of the board entering or changes in thickness. If only weights are used, although the pressure is constant, it lacks elastic buffering and cannot adapt to changes in thickness, resulting in instantaneous excessive or insufficient pressure, damaging the board. It also cannot guarantee that the film obtains uniform pressure on the entire surface, producing bubbles or localized poor bonding.

[0005] In summary, the common problems with existing fireproof board laminating machines are: difficulty in effectively solving the wrinkling problem of the film before hot pressing while applying stable and adaptive pressure, resulting in defects such as uneven surface and weak bonding in the final product.

[0006] Therefore, this utility model proposes a fireproof board surface coating laminating machine to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems of uneven pressure, weak bonding, and wrinkling of the film during heating in the existing fireproof board surface coating laminating machine, this utility model aims to provide a fireproof board surface coating laminating machine with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a fireproof board surface coating and laminating machine, including a frame, a roller at one end of the frame, and a pressing mechanism and a smoothing mechanism arranged sequentially on the frame along the feeding direction of the fireproof board.

[0009] The pressing mechanism includes a support frame 1 fixed on the machine frame and a connecting frame 1 adjustable above the support frame 1. A threaded rod is threadedly connected to the center of the upper part of the connecting frame 1. A fixed box is pressed and connected below the connecting frame 1, and a spring 1 is installed inside the fixed box. A connecting plate is connected to the bottom of the fixed box, and a connecting frame 2 is connected below the connecting plate. A pressure roller is installed on the connecting frame 2.

[0010] The smoothing mechanism includes a support frame two fixed on the frame, and a connecting frame three slidingly fitted inside the guide rail of the support frame two; the connecting frame three has a connecting column inside, a sleeve is fitted on the outside of the connecting column, a spring two is arranged around the connecting column and connected to the connecting frame three, and a counterweight is connected to the top of the connecting frame three; a smoothing roller and a heating roller are installed in sequence at the lower end of the connecting frame three.

[0011] Preferably, a plurality of rollers are rotatably connected to the support frame of the pressing mechanism. These rollers are used to provide stable travel support for the fireproof board before the pressure roller applies pressure.

[0012] Preferably, the connecting frame three in the smoothing mechanism reciprocates vertically along the guide rail of the support frame two. This sliding arrangement allows the heating roller to adapt to fireproof boards of different thicknesses, ensuring the bonding pressure.

[0013] Preferably, the fixing box is provided with multiple springs, the upper end of the springs abutting against the top plate of the fixing box, and the lower end of the springs abutting against the connecting plate, thereby forming a stable elastic buffer structure.

[0014] Preferably, the counterweight and spring 2 work together on the connecting frame 3. This combination of rigid gravity and elastic force can provide a constant and elastically buffered bonding pressure to the heating roller.

[0015] Preferably, the lengths of both the pressure roller and the heating roller are greater than the width of the fireproof board. This design ensures that the surface of the fireproof board can be completely covered during the lamination process, avoiding inadequate edge adhesion.

[0016] Preferably, the flattening roller is arranged in the feeding direction in front of the heating roller, so that the flattening roller is used to pre-flatten the film before the heating roller heats it, so as to effectively eliminate wrinkles.

[0017] Preferably, the connecting column is fixedly connected to the upper end of the connecting frame three. The connecting column not only serves as a fixing component, but also guides the movement of the spring two and the sleeve to ensure vertical stability.

[0018] Preferably, the connecting plate passes through the bottom plate of the fixing box and is fixedly connected to the connecting frame two. This through-connection method is used to stably transmit the pressure of the spring one inside the fixing box to the connecting frame two and the pressure roller.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model solves the problem of insufficient bonding pressure or single function leading to weak bonding in the prior art by setting up a pressing mechanism and a smoothing mechanism, and making the fireproof board pass through the pressing mechanism and smoothing mechanism in sequence. It achieves a two-stage coating effect of first cold pressing for positioning and then hot pressing for smoothing, thus improving the bonding quality.

[0021] 2. This utility model solves the problem of film wrinkling during heating and compaction in the prior art by setting a flattening roller in the flattening mechanism and positioning the flattening roller in front of the feeding direction of the heating roller. It achieves the process effect of flattening before heating, ensuring the flatness and smoothness of the film surface.

[0022] 3. This utility model solves the problem of unstable hot pressing pressure and difficulty in adapting to changes in sheet thickness in the prior art by using a counterweight and spring 2 to apply pressure in the smoothing mechanism, and by making the connecting frame 3 with the heating roller slide on the support frame 2. It achieves a hot pressing effect with constant pressure, sufficient buffering and adaptability to thickness, resulting in a more secure fit. Attached Figure Description

[0033] Reference Figure 2 and Figure 3 The pressing mechanism 2 includes a support frame 201 fixed on the frame 1. Multiple rollers 202 are rotatably connected to the support frame 201. The rollers 202 are used to support the fireproof board 4 to move smoothly before the pressure roller 208 applies pressure. A connecting frame 203 is provided above the support frame 201. The connecting frame 203 is adjustablely set on the support frame 201. A threaded rod 204 is threadedly connected to the upper center position of the connecting frame 203.

[0034] Please refer to Figure 4and Figure 5 The smoothing mechanism 3 includes a second support frame 301 fixed on the frame 1. A third connecting frame 302 is slidably fitted inside the guide rail of the second support frame 301. The third connecting frame 302 reciprocates vertically along the guide rail of the second support frame 301, so that the heating roller 306 can adapt to fireproof boards 4 of different thicknesses. A connecting post 305 is provided inside the third connecting frame 302. The connecting post 305 is fixedly connected to the upper end of the third connecting frame 302 and is used to guide the movement of the second spring 304 and the sleeve 303. The sleeve 303 is sleeved on the outside of the connecting post 305. The second spring 304 surrounds the connecting post 305. A connecting frame 302 is placed and connected; a counterweight 307 is connected to the top of the connecting frame 302, and the counterweight 307 and the spring 304 work together to provide a constant and elastic bonding pressure to the heating roller 306; a flattening roller 308 and a heating roller 306 are installed in sequence at the lower end of the connecting frame 302; the flattening roller 308 is set in the feeding direction in front of the heating roller 306, and the flattening roller 308 is used to pre-flatten the film before the heating roller 306 heats it to eliminate wrinkles; the length of the heating roller 306 is greater than the width of the fireproof board 4 to ensure complete coverage of the surface of the fireproof board 4.

[0035] As a preferred embodiment, please refer to Figure 2 Multiple rollers 202 are rotatably connected to the support frame 201 of the pressing mechanism 2. The rollers 202 are used to provide stable conveying and support for the fireproof board 4 before the pressure roller 208 applies pressure to it.

[0036] As another preferred embodiment, please refer to Figure 3 The fixing box 206 is equipped with multiple springs 205. The upper end of the spring 205 abuts against the top plate of the fixing box 206, and the lower end of the spring 205 abuts against the connecting plate 209, thereby forming an elastic buffer structure.

[0037] As another preferred embodiment, please refer to Figure 3 The connecting plate 209 passes through the bottom plate of the fixing box 206, and the connecting plate 209 is fixedly connected to the connecting frame 207 to transmit the pressure of the spring 205.

[0038] As another preferred embodiment, please refer to Figure 4 The connecting frame 302 in the smoothing mechanism 3 reciprocates vertically along the guide rail of the support frame 301. This sliding fit enables the heating roller 306 to adapt to the thickness change of the fireproof board 4.

[0039] As another preferred embodiment, please refer to Figure 5 The connecting post 305 is fixedly connected to the upper end of the connecting frame 302. The connecting post 305 is used to guide the movement of the sleeve 303 and the spring 2 304.

[0040] As another preferred embodiment, please refer to Figure 4 The flattening roller 308 is positioned in the feeding direction in front of the heating roller 306 and is used to pre-flatten the film.

[0041] As another preferred embodiment, please refer to Figure 4 The lengths of the pressure roller 208 and the heating roller 306 are both greater than the width of the fireproof board 4, ensuring complete coverage of the surface of the fireproof board 4.

[0042] Working principle: When the fireproof board 4 is fed, it will move on the frame 1. It is first supported by the roller 202 on the support frame 201. The film is drawn out from the roller 5 and covers the upper surface of the fireproof board 4.

[0043] Subsequently, the fireproof board 4 and the film enter the pressing mechanism 2 together. At this time, by adjusting the threaded rod 204, the connecting frame 203 moves downward, pressing the fixing box 206. The fixing box 206 compresses the spring 205 inside, and the spring 205 applies elastic force to the pressure roller 208 through the connecting plate 209 and the connecting frame 207. The pressure roller 208 applies preliminary cold pressure with elastic cushioning to the fireproof board 4 and the film.

[0044] The fireproof board 4, which has completed the initial pressing, continues to the smoothing mechanism 3. The fireproof board 4 first passes through the flattening roller 308, which pre-flattens the film to eliminate wrinkles.

[0045] Afterwards, the fireproof board 4 passes through the heating roller 306. At this time, the counterweight 307 fixed on the top of the connecting frame 302 provides a constant gravitational downward pressure, while the spring 2 304 provides an elastic downward pressure in cooperation with the connecting column 305 and the sleeve 303. These two forces work together on the connecting frame 302, which can slide vertically within the support frame 2 301, so that the heating roller 306 heats the film and finally compacts it.

[0046] By combining the elastic cold pressing of the pressing mechanism 2 and the flattening and hot pressing of the smoothing mechanism 3 with gravity and elasticity, this utility model solves the problem of uneven film pressure and wrinkles in the prior art, and achieves a flat and firm bonding effect.
