Description

Technical Field

[0001] The utility model relates to the technical field of PVC films, in particular to a winding device of a PVC film flattening machine. Background Art

[0002] During the PVC film production process, wrinkles, waves, or uneven stretching can easily occur during coating, stretching, or cooling. This can lead to surface unevenness, uneven tension, or irregular winding. These problems not only affect the film's appearance quality but can also impact subsequent processing steps such as printing, cutting, and packaging, and can even cause equipment damage or production line stalls. Furthermore, due to the physical properties of PVC film, such as its softness and uneven thickness, film tension control and leveling technology are particularly important throughout the production process. Without effective tension control and leveling, the film will often become loose, wrinkled, and unevenly stacked during the winding process, affecting the product's appearance and performance. Utility Model Content

[0003] The purpose of this utility model is to effectively remove wrinkles and unevenness that may occur in the PVC film during the production process through the design of the first adsorption roller and the second adsorption roller. The adsorption roller firmly adsorbs the film through uniform adsorption force, ensuring that the film remains flat during the leveling process without slipping or wrinkling.

The feeding device ensures that the film is fed evenly and continuously into the leveling system, reducing problems that may arise from uneven feeding. The adsorption device secures the film, preventing slippage or misalignment during the leveling and winding process. The coordination of the winding roller and the motor enables the film to be wound evenly and stably, preventing loose and irregular winding. The film, as the primary object of processing, is fed from the feeding device into the leveling device and, after leveling, enters the winding roller for winding.

The first and second adsorption rollers can accurately control the position of the film through the design of the adsorption holes to ensure that the film does not slip during the entire leveling process, thereby avoiding problems such as wrinkles and uneven stretching. The second chain ensures the synchronous rotation of the first adsorption roller and the second adsorption roller, which can effectively improve the leveling effect and avoid uneven film surface caused by inconsistent rotation speeds.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Combine Figures 1 to 3As shown, a PVC film flattening machine winding device includes a support frame 1, a flattening device 2 is provided on the upper end of the support frame 1, a feeding device 3 is provided on one side of the flattening device 2, an adsorption device 4 is fixedly connected to one side end of the support frame 1, a support plate 5 is provided at the lower end of the adsorption device 4, a winding roller 6 is provided at the lower end of the support frame 1, a first chain 7 is connected to the winding roller 6, a rotating motor 8 is fixedly connected to the bottom end of the support frame 1, and the rotating motor 8 and the winding roller 6 are assembled and connected through the first chain 7, the feeding device 3, the flattening device 2 and the winding roller Film 9 is provided through the guide 6. A flattening device effectively removes wrinkles from the film, ensuring the quality of subsequent processes or products. The feeding device ensures that the film is fed evenly and continuously into the flattening system, reducing problems that may arise from uneven feeding. The suction device secures the film, preventing slippage or misalignment during the flattening and winding processes. The coordination between the winding roller and the motor enables the film to be wound evenly and stably, preventing loose or irregular winding. The film, the primary object of processing, is fed from the feeding device into the flattening device and, after flattening, onto the winding roller for winding. Through the combined action of the flattening device, suction device, and winding roller, the film maintains excellent flatness during the winding process, avoiding quality problems caused by wrinkles or looseness.

[0018] Among them, the leveling device 2 includes a first adsorption roller 21, a second adsorption roller 22 is provided at one side end of the first adsorption roller 21, a second chain 23 is provided between the first adsorption roller 21 and the second adsorption roller 22, and the transmission connection is achieved through the second chain 23, a number of adsorption holes 24 are evenly arranged on the first adsorption roller 21 and the second adsorption roller 22, an adjusting clamping roller 25 is provided on one side end of the second adsorption roller 22, a first feeding roller 26 is provided at the lower end of the second adsorption roller 22, and a second feeding roller 27 is provided at one side end of the first feeding roller 26. The first and second adsorption rollers can accurately control the position of the film through the design of the adsorption holes to ensure that the film does not slip during the entire leveling process, thereby avoiding problems such as wrinkles and uneven stretching. The second chain ensures the synchronous rotation of the first adsorption roller and the second adsorption roller, which can effectively improve the leveling effect and avoid problems caused by inconsistent rotation speeds. The uneven surface of the film caused by the adjustment of the clamping roller makes the leveling device adaptable to PVC films of different thicknesses, ensuring the stability and consistency of the leveling effect. The design of the first and second feed rollers ensures that the film can be smoothly and efficiently transported from the leveling device to the subsequent process, avoiding the problems of uneven tension and misalignment during transportation; the adsorption device 4 includes a first suction pipe 41, and the adjacent end of the first suction pipe 41 is connected to the second suction pipe 42. A through pipe 43 is connected between the first suction pipe 41 and the second suction pipe 42, and one end of the through pipe 43 is connected to an exhaust fan 44. The combination of the first suction pipe, the second suction pipe and the exhaust fan effectively enhances the adsorption force of the film, ensuring that the film is firmly attached to the adsorption roller during the leveling process to prevent slippage or wrinkles. The first suction pipe 41 is connected to the first adsorption roller 21, and the second suction pipe 42 is connected to the second adsorption roller 22.

[0019] Working principle: The PVC film 9 is first fed into the leveling system from the feeding device 3. The feeding device ensures that the film can be fed into the leveling device 2 evenly and continuously through its unique design. This process maintains the tension balance of the film, avoids wrinkling or uneven feeding of the film during feeding, and reduces subsequent problems that may be caused by uneven feeding. After the material reaches the leveling device, the film enters the leveling mechanism composed of the first adsorption roller 21 and the second adsorption roller 22. At this stage, the film is firmly adsorbed by the adsorption roller through its evenly distributed adsorption holes 24. The first adsorption roller and the second adsorption roller are synchronously driven by the second chain 23 to ensure that the film can move smoothly between the two rollers to prevent wrinkles or uneven surfaces caused by inconsistent rotation speeds. At the same time, the clamping roller 25 is adjusted to adapt to PVC films of different thicknesses by adjusting the clamping force of the film, thereby ensuring the stability and consistency of the leveling effect. The adsorption device is connected to the second suction tube 41 42 through the first suction tube 41 to form a negative pressure system, which further enhances the adsorption force of the film on the adsorption roller. After the film is fed into the leveling device, the negative pressure generated by the adsorption device through the exhaust fan 44 makes the film firmly adhere to the adsorption roller to avoid slipping or dislocation during the leveling process. The adsorption device ensures that the film always maintains the correct position during the leveling process to prevent wrinkles or uneven stretching caused by slippage. The leveled film passes through the leveling device smoothly and is fed into the winding roller 6. The winding roller is connected to the rotating motor 8 through the first chain 7. The motor drives the winding roller to rotate so that the film is evenly and stably wound. The design of the winding roller can ensure that the film always maintains appropriate tension during the winding process, avoiding loose or irregular winding. By cooperating with the motor, the winding roller can adjust the winding speed and force to ensure the flatness and quality of the film winding.
