Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a PVC laminating film cooling and shaping device. Background Technology

[0002] In modern industrial production, PVC laminated film is widely used in many fields such as furniture manufacturing, building decoration, and automotive interiors due to its excellent waterproofness, wear resistance, and rich decorative properties. In the production process of PVC laminated film, cooling and shaping is an indispensable key step. The cooling and shaping device removes the heat generated by the PVC laminated film during the production process through a cooling medium (usually coolant or cooling gas), so that it can be quickly cured and shaped, thereby ensuring the dimensional accuracy, surface flatness, and physical properties of the product.

[0003] Most PVC laminating film cooling and shaping devices on the market currently use circulating cooling systems to improve the utilization rate of the cooling medium and reduce production costs. However, during the circulation of the cooling medium, various impurities inevitably get mixed in. The presence of these impurities reduces the heat exchange efficiency of the cooling medium. When the cooling medium containing impurities comes into contact with the PVC laminating film or cooling components, the impurities will form an isolation layer on the contact surface, hindering heat transfer and causing a decrease in cooling effect. This will not only prolong the cooling time of the PVC laminating film and reduce production efficiency, but may also cause uneven heating of the PVC laminating film during the cooling process, resulting in quality problems such as local deformation and surface wrinkles, affecting the appearance and performance of the product. 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 laminating film cooling and shaping device. This device can solve the problem that various impurities inevitably mix into the cooling medium during the recycling process. The presence of these impurities will reduce the heat exchange efficiency of the cooling medium. When the cooling medium containing impurities comes into contact with the PVC laminating film or cooling components, the impurities will form an isolation layer on the contact surface, hindering the transfer of heat and causing a decrease in cooling effect. This will not only prolong the cooling time of the PVC laminating film and reduce production efficiency, but may also cause uneven heating of the PVC laminating film during the cooling process, resulting in quality problems such as local deformation and surface wrinkles, affecting the appearance and performance of the product.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a PVC laminating film cooling and shaping device, comprising a cooling box, a winding mechanism and a storage box, wherein a filter assembly is provided on the cooling box; The filter assembly includes a sliding seat, a filter mechanism, and a connecting pipe.

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of "first" and "second" in the description 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 A typical example of a conventional filtration system (coarse filter + fine filter + conical positioning slider). Suitable for general production environments where the cooling medium contains few impurities, the filtration mechanism uses a combination of standard coarse and fine filters. The coarse filter intercepts larger particles, while the fine filter filters out tiny particles. The positioning slider uses a tapered positioning slider that engages with the tapered groove of the positioning slide to achieve quick and accurate positioning. A fixing bolt passes through the protrusion and is then tightened into the fixing bolt groove. In daily production, this combination effectively filters common impurities in the cooling medium. The tapered positioning slider ensures the filtration mechanism is securely installed, and it can be disassembled by unscrewing the bolts. Suitable for small and medium-sized PVC film manufacturers.

[0023] Example 2: Reference Figure 5 Example of high-efficiency filtration in high-impurity environments (multi-layer composite filter + magnetic positioning slider) For production environments with high impurity content and complex particles in the cooling medium, such as recycling processing scenarios, the filtration mechanism is replaced with a multi-layer composite filter, including a coarse filter layer, an activated carbon adsorption layer, and a fine filter layer. It can simultaneously filter particles, adsorb odors and chemical impurities. The positioning slider adopts a magnetic positioning slider, which is strongly attracted to the magnetic seat in the positioning groove, enhancing installation stability. In high-impurity environments, the multi-layer composite filter deeply purifies the cooling medium, and the magnetic positioning slider ensures that the filtration mechanism does not loosen under the impact of water flow, effectively protecting the downstream storage tank and equipment and extending its service life.

[0024] Furthermore, when using this device, the PVC laminating film enters through the feed inlet of the cooling box 1 and is smoothly guided into the cooling box 1 by the guide roller 5. At this time, the tensioning roller mechanism 17, under the action of the cylinder 2, adjusts the position of the tensioning roller according to the thickness, material, and other characteristics of the PVC laminating film, tensioning the PVC laminating film to ensure that the film remains flat during the cooling process and avoids problems such as wrinkles caused by loosening. At the same time, inside the cooling box 1, the PVC laminating film is in full contact with the cooling medium, and the cooling medium carries away the heat on the film, allowing it to gradually cool and solidify. After cooling and solidification, the PVC laminating film is guided by the guide roller. Guided by 5, the material leaves the outlet of the cooling box 1 and enters the winding mechanism 3. The drive mechanism of the winding mechanism 3 drives the winding roller to rotate, winding up the cooled and shaped PVC laminate film, completing the entire cooling, shaping, and winding process. The cooling medium in the cooling box 1, after heat exchange and temperature increase, flows into the connecting pipe 19 through the water outlet pipe 6. Under the suction of the water pump 7, the cooling medium in the connecting pipe 19 first passes through the filter mechanism 12 installed on the sliding seat 10. The cooling medium first passes through the coarse filter screen, where larger particulate impurities such as PVC particle fragments and larger metal fragments are intercepted. Then it passes through... The coarsely filtered cooling medium continues to pass through a fine filter screen, where tiny particulate impurities are further filtered out, ensuring a high level of cleanliness for the cooling medium entering storage tank 4. The filtered cooling medium is then pumped by water pump 7 through a connecting pipe into storage tank 4 for storage. When cooling tank 1 needs replenishment, the cooling medium in storage tank 4 flows back into cooling tank 1 through the connecting pipe and the inlet pipe, achieving recycling of the cooling medium. When cleaning or replacing the filter mechanism 12 is required, the operator can unscrew the fixing bolts 8 to disengage the protrusion 11 from the groove 16, and then use... The sliding engagement between the sliding seat 10 and the sliding seat groove 15 allows the sliding seat 10 to be pulled out from the connecting pipe 19. If the positioning slider 9 is a magnetic positioning slider 18, the sliding seat 10 can be pulled out simply by overcoming the attraction between the magnetic block and the magnetic seat. After replacement or cleaning, the sliding seat 10 is reinserted into the sliding seat groove 15 so that the positioning slider 9 and the positioning groove 14 are engaged and positioned. The protrusion 11 is inserted into the groove 16, and the fixing bolt 8 is tightened to complete the installation of the filter mechanism 12. This ensures that the filter assembly can work continuously and stably, protects the cleanliness of the cooling medium, and thus ensures the cooling and shaping quality of the PVC laminated film.

[0025] The filtration mechanism 12, which combines a coarse filter and a fine filter in the filtration assembly, can perform graded filtration of impurities in the cooling medium. First, the coarse filter intercepts large particles such as PVC granules and larger metal fragments, and then the fine filter further filters out tiny particles, greatly improving the filtration accuracy. This effectively prevents impurities from forming an isolation layer on the contact surface between the cooling medium and the PVC lamination film or cooling components, ensuring good heat exchange efficiency of the cooling medium, shortening the cooling time of the PVC lamination film, and improving production efficiency.

[0026] Structural Description: Sliding seat 10: As the basic carrier of the filter assembly, its outer wall is slidably connected to the sliding seat groove 15 of the connecting pipe 19, realizing the mobility of the sliding seat 10 on the connecting pipe 19. Two positioning sliders 9 (which can be conical positioning sliders or magnetic positioning sliders 18) are fixedly connected to the left and right outer walls for positioning within the sliding seat groove 15, ensuring the stability of the sliding seat 10 after installation. At the same time, protrusions 11 are also fixedly connected to the left and right outer walls. The protrusions 11 cooperate with the grooves 16 and are connected to the fixing bolt grooves 13 by fixing bolts 8, further enhancing the fixing effect. Filter mechanism 12: Composed of a coarse filter and a fine filter, it is fixedly installed on the inner wall of the sliding seat 10 and is the core of the filter assembly. The coarse filter first intercepts larger particulate impurities, and the fine filter further filters out tiny particles, ensuring the cleanliness of the cooling medium. Connecting pipe 19: A sliding seat groove 15 is formed on the outer wall of one end for mating with the sliding seat 10. The other end is connected to the outlet pipe 6 of the cooling box 1 via a flange, forming an outlet channel for the cooling medium. Positioning grooves 14, grooves 16, and fixing bolt grooves 13 are formed on the left and right inner walls, which respectively mate with the positioning slide 9, protrusion 11, and fixing bolt 8 on the sliding seat 10 to achieve the installation and fixation of the filter assembly. (iii) Other components Cooling box 1: A cylinder 2 is mounted on the upper surface, and a tension roller mechanism 17 is installed inside. Guide rollers 5 are rotatably installed at the inlet and outlet. The output end of the cylinder 2 is connected to the tension roller mechanism 17, allowing adjustment of the tension roller position. The guide rollers 5 are used to guide the PVC laminating film in and out of the cooling box 1. A water outlet pipe 6 is installed on the outer wall of one end of the cooling box 1 to discharge the cooling medium. Rewinding mechanism 3: Composed of a bracket, a winding roller, and a drive mechanism, it is mounted on the upper surface of the discharge port of cooling box 1 via the bracket. The drive mechanism drives the winding roller to rotate, thereby rewinding the cooled and shaped PVC laminated film. Storage tank 4: Connected to the water inlet pipe of cooling tank 1 via a connecting pipe, it receives the filtered and circulated cooling medium. Water pump 7: The inlet end is connected to the end of the connecting pipe 19 furthest from the outlet pipe 6, and the outlet end is connected to the upper outer wall of the storage tank 4. It provides power for the circulation of the cooling medium, enabling the cooling medium to circulate between the cooling tank 1, the filter assembly, and the storage tank 4. Tensioning roller mechanism 17: Composed of a fixed frame and a tensioning roller. The fixed frame is connected to the output end of cylinder 2 and can move up and down under the action of cylinder 2 to adjust the tension of the PVC laminating film and ensure the flatness of the film during the cooling process. Guide roller 5: Installed at the inlet and outlet of cooling box 1, it guides the PVC laminating film to enter and exit cooling box 1 smoothly, and prevents the film from shifting or wrinkling during the process.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
