Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a PVC film heat-conducting oil heating and bonding device. Background Technology

[0002] In modern industrial production, PVC film is widely used in furniture manufacturing, building decoration, packaging materials and other fields due to its good wear resistance, corrosion resistance, aesthetics and cost advantages. Taking furniture manufacturing as an example, by laminating PVC film onto the surface of the board, the board can be given a variety of appearance effects such as wood grain and stone grain, while improving the moisture resistance and wear resistance of the board, which greatly meets the market demand for high-quality furniture.

[0003] Existing PVC film heat-conducting oil heating and laminating devices mainly utilize heat-conducting oil as a heat transfer medium to evenly transfer heat to components such as heating rollers or heating plates. After the PVC film softens due to heating, it is tightly bonded to the board through a pressing mechanism. Although these devices can complete the bonding task of PVC film and board to a certain extent, in actual production, some devices simply rely on pressing rollers to squeeze the PVC film and board in an attempt to expel air. However, because the surface of the pressing roller is relatively smooth, air cannot be effectively guided and expelled during the squeezing process, resulting in a large amount of air being trapped between the film and board, forming air bubbles. Even if some air can be squeezed out, it is difficult to ensure that the bonding surface is completely flat, and small air bubbles or wrinkles are easily left behind, which in turn damages the overall flatness and aesthetics, reduces the visual effect and quality of the product, and makes the product lack an advantage in market competition. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a PVC film heat-conducting oil heating and bonding device. This device can solve the problem that some devices rely solely on simple pressing rollers to squeeze the PVC film and the board in an attempt to expel air. However, because the surface of the pressing rollers is relatively smooth, air cannot be effectively guided and discharged during the squeezing process, resulting in a large amount of air being trapped between the film and the board, forming air bubbles. Even if some air can be squeezed out, it is difficult to ensure that the bonding surface is completely flat, and small air bubbles or wrinkles are easily left behind, which in turn damages the overall flatness and aesthetics, reduces the visual effect and quality of the product, and causes the product to lack competitiveness in the market.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PVC film heat-conducting oil heating and bonding device, comprising a support base, a feeding mechanism, a guiding mechanism, a heat-conducting oil heating roller mechanism, and a transport mechanism, wherein the support base is provided with a de-bubbling component; The debubbling assembly includes a pressing roller, two first support frames, and two second support frames.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Example 1: Reference Figure 1-4 Conventional bonding basic embodiment (10 corrugated pressing rollers + 7 flexible scrapers) Suitable for laminating PVC films of ordinary thickness and with a flat surface, the basic function of removing air bubbles is achieved through the corrugated pressing roller 10 and the flexible scraper 7. The pressing roller 10 adopts a corrugated design, and the undulating surface gradually squeezes the PVC film during the rolling process, driving the air bubbles to the edge. The flexible scraper 7 is made of ordinary rubber and adheres to the surface of the PVC film to further scrape off residual air bubbles. In regular production, the corrugated pressing roller 10 applies pressure evenly, and the flexible scraper 7 cleans the air bubbles in time. It is suitable for daily PVC film laminating operations in small and medium-sized factories, and is simple to operate and low in cost.

[0023] Example 2: Reference Figure 5 Thick film bonding reinforcement embodiment (multi-groove pressing roller 17 + thickened flexible scraper) For thicker PVC films, a multi-groove pressing roller 17 and a thickened flexible scraper are used to improve the de-bubble effect. The pressing roller 10 is replaced with a multi-groove pressing roller 17. The densely packed grooves on the surface can increase the contact area with the PVC film and enhance the ability to squeeze out bubbles. The flexible scraper 7 is thickened and its hardness is increased, which can more effectively scrape out stubborn bubbles in the thick film. When laminating the thick film, the grooves of the multi-groove pressing roller 17 precisely squeeze out the bubbles, and the thickened scraper applies force to ensure that there are no bubble residues after laminating the thick film. It is suitable for thick film processing scenarios such as architectural decoration and advertising inkjet printing.

[0024] Furthermore, when using this device, after the PVC film heat transfer oil heating and bonding device is started, the PVC film on the feeding mechanism 2 (composed of a feeding roller and two supports) begins to be released. Guided by the feeding mechanism 3 (composed of two fixed frames and a guide roller), the PVC film is smoothly conveyed to the heat transfer oil heating roller mechanism 4. Driven by the driving mechanism, the heat transfer oil heating roller in the heat transfer oil heating roller mechanism 4 uses the heat transferred by the heat transfer oil to heat the PVC film, softening it and facilitating subsequent bonding with the board. Then, the softened PVC film... The C-film continues to be conveyed forward, merging with the sheet material on the transport mechanism 9 (composed of multiple conveying rollers and a drive mechanism), and together they enter the working area of ​​the de-bubble assembly. At this time, the pressing roller 10 (a corrugated pressing roller or a multi-groove pressing roller 17) begins to function. The special texture on the surface of the corrugated pressing roller or the multi-groove pressing roller 17 comes into contact with the sheet material and the PVC film during rotation, forming an air guiding channel. This allows the air between the PVC film and the sheet material to be discharged to both sides along the gaps in the texture. At the same time, after the pressing roller 10 completes the initial extrusion and degassing... The flexible scraper 7, located behind the pressing roller 10, begins to operate. The flexible scraper 7 is fixed to two second sliders 11 via connecting rods 12. The two second sliders 11 slide within the guide grooves 16 of the second support frame 6 and engage with the first adjusting threaded rod 13. When the rotating block 15 rotates, it drives the first adjusting threaded rod 13 to rotate, thereby causing the second sliders 11 to move up and down, adjusting the contact pressure between the flexible scraper 7 and the surface of the pressing roller 10. The flexible scraper 7 is made of silicone rubber, and under appropriate pressure, it can squeeze the pressing roller 10... After pressing, any remaining air bubbles are completely squeezed out, and the surface of the PVC film is smoothed to ensure a flat and bubble-free bonding surface. Then, the bonded board and PVC film assembly is transported by the transport mechanism 9 to the device outlet to complete the entire bonding process. During operation, the operator can adjust the height of the flexible scraper 7 and the pressing roller 10 by rotating the rotating block 15 and using the first adjusting threaded rod 13 and the second adjusting threaded rod 14, according to actual production needs, to accommodate boards and PVC films of different thicknesses and ensure bonding effect.

[0025] The de-bubble assembly uses a corrugated or multi-groove pressing roller 17 for the pressing roller 10. The special texture on its surface forms an air channel during the rotating pressing process. When the PVC film and the sheet pass through the pressing roller 10, the air can be quickly discharged to both sides along the gaps in the texture. Compared with the traditional smooth pressing roller, the air exhaust efficiency is greatly improved. In addition, the flexible scraper 7 located behind the pressing roller 10, through the silicone rubber material and appropriate contact pressure, can completely squeeze out the tiny air bubbles remaining after the pressing roller 10 is squeezed and smooth the surface, so that the bonding surface achieves a flat and bubble-free effect, which greatly improves the visual effect and quality of the product and enhances the product's competitiveness in the market.
