Description

Technical Field

[0001] The invention relates to the field of PVC film production, in particular to a PVC decorative film production device. Background Art

[0002] The main component of PVC is polyvinyl chloride, which is slightly yellow and translucent and shiny. Its transparency is better than that of polyethylene and polypropylene, but worse than that of polystyrene. Depending on the amount of additives used, it is divided into soft and hard polyvinyl chloride. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene, but lower than that of polypropylene, and whitening will occur at the bends. Common products: plates, pipes, soles, toys, doors and windows, wire sheaths, stationery, etc.

[0003] After massive searches, it was found that the prior art publication number is CN115091738B, which discloses a transparent PVC decorative film processing device and production method, including a base, a feeding roller is arranged at one end of the base, and a printing roller and a water-cooling roller are arranged at the rear end of the feeding roller in sequence, and the outer sides of the printing roller and the water-cooling roller are provided with tensioning rollers and guide rollers for adjusting the tension and guiding the PVC film, and a pressing roller is additionally arranged below the printing roller for auxiliary printing, and a winding roller is arranged at the tail end of the base for winding the film, and the water-cooling roller is a nested interlayer roller, and the cooling liquid is introduced into the middle section of the water-cooling roller through the inner channel and then introduced and guided into the interlayer, and the water in the water-cooling roller is guided to the middle section of the water-cooling roller through the inner channel and flows out, and then moves circumferentially around the water-cooling roller and is discharged from the middle section, thereby avoiding the temperature difference on both sides caused by one end in and one end out, improving the balance of the surface performance of the film, improving the quality, and having good development prospects.

[0004] In the above-mentioned prior art, after the hot-melt extrusion molding process of the PVC material, the PVC material is rolled into a suitable thickness to form a PVC film.

[0046] The working principle of the present invention is as follows: when it is necessary to produce a PVC decorative film, the required PVC material is placed in a melting box 202 for heating, and the heated and melted PVC material is transferred to an extruder 203, and the extruder 203 transfers the PVC material to one end of an extrusion sleeve 204, and the extruded PVC film passes through between the shaping cylinders 206, so that the shaping cylinders 206 shape and extrude the just-extruded PVC film, and play a certain role in cooling the temperature, thereby avoiding damage to the PVC film caused by extrusion when the PVC film is extruded into a suitable thickness;

[0047] After the PVC film moves to the top of the extrusion plate 301, the driving motor 303 is started, the fixing rod 304 drives the fixing sleeve 305 to start rotating, and the fixing frame 307 starts rotating, so that the multiple extrusion cylinders 308 squeeze the PVC film, and when the PVC film is expanded to a suitable width, the surface of the PVC film is made smoother;

[0048] After the PVC film is squeezed, the PVC film contacts the temperature detector 510 provided on the surface of the temperature measuring tube 509. The temperature detector 510 transmits the detected data to the lifting controller 517, so that the lifting controller 517 controls the cooling telescopic rod 516 to start to shrink. The water bag sleeve 515 is filled with water and adheres to the PVC surface. Under the action of tension, the closer the distance between the cooling tube 519 and the PVC film is, the larger the contact area between the water bag sleeve 515 and the PVC is, thereby increasing the cooling phase distance and making the cooling of the PVC film more complete.

[0049] When the water pump 522 is started, the water pump 522 transfers the water in the cooling box 508 to the cooling pipe 519 through the water inlet pipe 521, and then enters the water bag cover 515 through the water hole provided in the cooling pipe 519, so that the water bag cover 515 is filled with coolant to cool the PVC film;

[0050] At the same time, when the PVC film continues to move, after the PVC film reaches the upper end of the cooling plate 503, the PVC film passes between the cooling plate 503 and the water bag sleeve 515. Under the action of gravity, the coolant in the water bag circle adheres to the surface of the PVC film, so that the PVC film is cooled more evenly.

[0051] When the water temperature in the water bag sleeve 515 begins to rise to a suitable temperature, the liquid in the temperature measuring circle 523 is transferred to the hydraulic telescopic rod 525 through the temperature measuring tube 524, so that the hydraulic telescopic rod 525 pushes the power-carrying circle 526 to start moving, and the resistance of the resistance rod 527 begins to change;

[0052] After the PVC film is cut into a suitable size, the winding motor 408 is started to make the winding drum 409 start to rotate. The winding drum 409 winds the cut PVC film and collects it on the outer wall of the winding drum 409. When it is collected to a suitable length, the hydraulic cutter 407 is started to cut off the excess PVC film.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
