Description

Technical Field

[0001] This utility model relates to the field of polypropylene film wrinkle removal technology, and in particular to a wrinkle removal device for polypropylene film processing. Background Art

[0002] Biaxially oriented polypropylene film is generally a multilayer co-extruded film, which is made by co-extruding polypropylene particles into sheets and then stretching them in both longitudinal and transverse directions. Therefore, this type of film has good physical stability, mechanical strength, air tightness, high transparency and gloss, and is tough and wear-resistant. It is currently the most widely used printing film.

[0003] Chinese patent literature discloses a wrinkle removal device for biaxially oriented polypropylene film that is easy to install (authorization announcement number CN219855954 U). It includes a table with base blocks installed at the four corners of the lower end. A flattening box is installed in the middle of the upper end of the table, and a fixing frame is installed on the upper right side of the flattening box. Support blocks are installed on both sides of the rear end wall of the table, and rotating rods are rotatably mounted in the middle of each support block. The rotating rods have threads on their surfaces, and clamping circular plates are installed at the inner ends of each rotating rod. Four connecting strips are provided around the clamping circular plates. While the above technical solution allows for easy installation by rotating the two rotating rods and rotating the clamping circular plates inward, the film tip enters between two wrinkle removal heating rollers. The heating rollers are activated to heat the wrinkle removal heating rollers, performing a second wrinkle removal operation, thus improving the wrinkle removal efficiency and reducing the operation time. However, in this technical solution, the longitudinal distance between the two wrinkle-removing heating rollers in the second wrinkle removal process cannot be adjusted, so it cannot be used for wrinkle removal of films of different thicknesses, thus limiting the scope of application of wrinkle removal.

[0028] Example

[0029] refer to Figures 1 to 6 A wrinkle-removing device for polypropylene film processing includes a frame 7, a primary wrinkle-removing device 2 and a secondary wrinkle-removing device 3 mounted on the frame 7. The primary wrinkle-removing device 2 includes a flattening box 21. The secondary wrinkle-removing device 3 includes a fixed frame 31 and an upper wrinkle-removing heating roller 321 and a lower wrinkle-removing heating roller 322 arranged vertically on the fixed frame 31. The lower wrinkle-removing heating roller 322 is rotatably connected to the fixed frame 31, and the upper wrinkle-removing heating roller 321 is connected to the fixed frame 31 via a first lifting assembly. When the first lifting assembly operates, it can drive the upper wrinkle-removing heating roller 321 to move away from or closer to the lower wrinkle-removing heating roller 322. With this structure, by installing the first lifting assembly, the longitudinal distance between the upper wrinkle-removing heating roller 321 and the lower wrinkle-removing heating roller 322 can be adjusted, thereby enabling the two wrinkle-removing heating rollers 322 to remove wrinkles from films of different thicknesses, thus improving the applicability of the wrinkle-removing device.

[0030] There are two fixed frames 31, which are symmetrically arranged on both sides of the frame 7. One end of the lower wrinkle-removing heating roller 322 is connected to the rotating motor 33, and the other end is rotatably connected to the fixed frame 31. There are two first lifting components, which are respectively arranged corresponding to the fixed frames. Heating rollers 32a are installed inside both the upper and lower wrinkle-removing heating rollers 321 and 322. With this structure, by setting two fixed frames 31, it can be ensured that when the lead screw 51 is engaged with the lifting plate 52, the upper wrinkle-removing heating roller 321 will not rotate, but will move up or down along the lead screw 51.

[0031] It also includes a dust removal device 1 mounted on the frame 7. The dust removal device 1 is located in front of the primary wrinkle removal device 2 along the film conveying direction. The dust removal device 1 includes a dust removal bracket 11, an upper dust removal roller 12 and a lower dust removal roller 13 distributed vertically. The lower dust removal roller 13 is rotatably connected to the dust removal bracket 11. The upper dust removal roller 12 is connected to the dust removal bracket 11 through a second lifting assembly. The second lifting assembly moves to drive the upper dust removal roller 12 to move away from or closer to the lower dust removal roller 13. The upper dust removal roller 12 and the lower dust removal roller 13 may be rubber rollers with bristles. This structure, by installing a dust removal device 1 consisting of an upper dust removal roller 12 and a lower dust removal roller 13 in front of the primary wrinkle removal device 2, allows for the removal of lint and dust from both the upper and lower surfaces of the film, thereby improving the dust removal effect and the production quality of the film. Furthermore, the design of the second lifting component allows for adjustment of the longitudinal distance between the upper dust removal roller 12 and the lower dust removal roller 13, enabling the two dust removal rollers to remove lint and dust from films of different thicknesses, making it highly practical.

[0032] Both the first and second lifting assemblies include a lead screw 51 and a lifting plate 52 meshing with the lead screw 51. An upper dust removal roller and an upper wrinkle-removing heating roller are rotatably connected to the lifting plate. They also include a drive assembly for driving the lead screw 51 to rotate. The drive assembly includes a first gear 53 and a second gear 54 meshing with the first gear 53. The second gear 54 is sleeved on the lead screw 51. The first lifting assembly is equipped with a drive motor 55 that drives the first gear 53 to rotate. A drive wheel 56 is sleeved on the output shaft of the drive motor 55. A driven wheel 57 is sleeved on the axle of the first gear 53 on the second lifting assembly. The driven wheel 57 and the drive wheel 56 are connected by a transmission belt 58. This structure ensures the stability of the transmission.

[0033] In this embodiment, the wrinkle removal device 2 further includes a support frame 24 disposed on the top of the flattening box 21. Two drive cylinders 22 are mounted on the support frame 24. The drive end of the drive cylinder 22 passes through the flattening box 21 and is connected to the pressure seat 23 located inside the flattening box 21. The drive cylinder 22 is a drive cylinder.

[0034] The winding device 4 includes a winding bracket 41 and a winding roller 43 rotatably connected to the winding bracket 41. A winding motor 42 is mounted on the winding bracket 41 to drive the winding roller 43 to rotate. The winding roller 43 is composed of a support roller 431 and several extension rollers 432 spliced ​​together, and the side of the support roller 431 away from the extension rollers 432 is fixedly connected to the output shaft of the winding motor 42. With this structure, by designing the winding roller 43 as an integral structure composed of a support roller 431 and multiple extension rollers 432 spliced ​​together, the length of the winding roller 43 can be adjusted according to the width of the film being wound by loading and unloading the extension rollers 432, thus increasing the applicability of the winding roller 43.

[0035] Each extension roller 432 has a locking block 61 at its left end, and both the support roller 431 and the extension roller 432 have locking grooves 62 that fit the locking block 61. The sidewalls of both the locking block 61 and the locking groove 62 have fixing holes 63, with fastening bolts 64 threaded into the fixing holes 63. This structure, employing the fastening bolts 64 and the locking block 61 engaging with the locking groove 62, effectively improves the working stability of the take-up roller 43.

[0036] When using the polypropylene film processing wrinkle removal equipment, start the winding motor 42, which will drive the winding device 4 to rotate, thereby conveying the film on the entire equipment. Specifically, the film will first go through a dust removal step. The specific process of the dust removal step is as follows: the front end of the film enters between the upper dust removal roller 12 and the lower dust removal roller 13. The rotating upper dust removal roller 12 and lower dust removal roller 13 can clean both sides of the film, that is, they can stick lint and dust to both sides of the film to remove lint and dust from the surface of the film, thereby improving the dust removal effect and improving the production quality of the film.

[0037] After dust removal, the film enters the primary wrinkle removal device 2. The front end of the film enters the flattening box 21. The two drive cylinders 22 are activated, and the drive cylinders 22 drive the pressure seat 23 to move downward to squeeze the film and achieve the first wrinkle removal.

[0038] The film after the first wrinkle removal process will enter the second wrinkle removal process. The front end of the film enters between two wrinkle removal heating rollers 32. The heating rollers are activated to heat the wrinkle removal heating rollers 32 to heat and flatten the film, thus achieving the second wrinkle removal.

[0039] The film tip is wound onto the take-up roller 43, and the take-up is started. The take-up motor 42 drives the take-up roller 43 to rotate to take up the film, thereby realizing automated wrinkle removal. After the take-up roller 43 has finished winding, the extension roller 432 closest to the support roller 431 is disassembled to allow the next film to be wrinkle removed.

[0040] When it is necessary to adjust the longitudinal distance between the upper wrinkle-removing heating roller 321 and the lower wrinkle-removing heating roller 322, the drive motor 55 is started. The rotation of the output shaft of the drive motor 55 drives the rotation of the first gear 53 connected to it. Under the action of the meshing connection between the first gear 53 and the second gear 54, the lead screw 51 can rotate. Since the lifting plate 52 and the lead screw 51 are threadedly connected, the lifting plate 52 can move up and down to adjust the longitudinal distance between the upper wrinkle-removing heating roller 321 and the lower wrinkle-removing heating roller 322. Thus, the secondary wrinkle removal device 3 can remove wrinkles from films of different thicknesses, which is highly practical. During the rotation of the output shaft of the drive motor 55, the drive wheel 56 connected to it will rotate. The drive wheel 56 drives the driven wheel 57 to rotate through the transmission belt 58, which in turn drives the first gear 53 connected to it through the wheel axle to rotate. Under the action of the meshing connection between the first gear 53 and the second gear 54, the lead screw 51 can rotate. Since the lifting plate 52 and the lead screw 51 are threadedly connected, the lifting plate 52 can move up and down, so as to synchronously adjust the longitudinal distance between the upper dust removal roller 12 and the lower dust removal roller 13. Thus, the dust removal device 1 can remove dust from films of different thicknesses, which is highly practical.

[0041] When a wider film needs to be wound, the corresponding fastening bolts 64 are removed, and a new extension roller 432 is inserted into the extended position and fixed, thereby making the winding roller 43 longer so that it can wind a wider film. The length of the winding roller 43 can be adjusted according to the width of the fabric being wound, increasing the applicability of the winding roller 43; and vice versa.

[0042] It should be noted that the electrical components in this application are connected to an external power source and control system, and the drive cylinder 22 is connected to an external air source. The control system can adopt the structure in the prior art and can be configured with a switch button and other structures. The control system is used to control the operation of the drive motor 55, the winding motor 42, the rotating motor 33 and the drive cylinder 22.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
