In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0035] Please refer to Figure 1 An embodiment of the present application provides a film roll forming device, which includes a frame 10, a first roller seat 20, a first roller 30, a second roller seat 40, a second roller 50, a seam adjustment device 60 and a pressure drive component 70.

[0036] The frame 10 is used to provide a mounting base. The first roller seat 20, the second roller seat 40 and the pressure driving member 70 are all mounted on the frame 10.

[0037] The second roller seat 40 can be moved away from the first roller seat 20 or moved close to the first roller seat 20. In other words, the interval between the first roller seat 20 and the second roller seat 40 can be adjusted.

[0038] The first roller 30 is rotatably mounted on the first roller base 20. The second roller 50 is rotatably mounted on the second roller base 40. A gap is defined between the second roller 50 and the first roller 30 to allow for film production. It will be appreciated that by moving the second roller base 40, the second roller 50 follows suit, thereby adjusting the gap between the second roller 50 and the first roller 30, and thus adjusting the thickness of the film.

[0039] The gap adjustment device 60 includes a wedge assembly 61 between the first roller seat 20 and the second roller seat 40. The wedge assembly 61 can adjust its width between the first roller seat 20 and the second roller seat 40. It can be understood that the width of the wedge assembly 61 between the first roller seat 20 and the second roller seat 40 is the minimum distance between the first roller seat 20 and the second roller seat 40.

[0040] The pressure driving member 70 drives the second roller seat 40 and the wedge assembly 61 to move toward the first roller seat 20 , and provides pressure to continuously clamp the wedge assembly 61 between the second roller seat 40 and the first roller seat 20 .

[0041] It is understood that the first roller 30 is rotatably mounted on the first roller seat 20, and the second roller 50 is rotatably mounted on the second roller seat 40, with a gap for film production being defined between the second roller 50 and the first roller 30. The wedge assembly 61 adjusts its width, and then the pressure-driven member 70 drives the second roller seat 40 toward the first roller seat 20, causing the second roller seat 40 and the wedge assembly 61 to abut against each other, and the wedge assembly 61 to abut against the first roller seat 20.

[0042] The pressure drive 70 continues to provide pressure to keep the wedge assembly 61 clamped between the second roller seat 40 and the first roller seat 20. The above pressure can eliminate the small gap between the first roller seat 20, the wedge assembly 61 and the second roller seat 40, thereby achieving fine adjustment of the interval between the first roller seat 20 and the second roller seat 40, thereby achieving fine adjustment of the gap between the first roller 30 and the second roller 50, and ensuring the thickness accuracy requirements of the film.

[0043] In some embodiments, a discharge hopper 87 is provided above the first roller 30 and the second roller 50 . The discharge hopper 87 is used to hold the polyphenylene sulfide film material. The discharge hopper 87 has a discharge port aligned with the gap between the first roller 30 and the second roller 50 .

[0044] To further fine-tune the gap between the first roller 30 and the second roller 50, in some embodiments, the pressure applied by the pressure driver 70 is adjustable to adjust the force of the clamping wedge assembly 61 between the second roller base 40 and the first roller base 20. This allows for further fine-tuning of the gap between the first roller 30 and the second roller 50. This adjustment method is simple and highly efficient.

[0045] It is understandable that the specific structure of the pressure driving member 70 is not limited. For example, a linear motor can be used to provide drive and pressure.

[0046] In some embodiments, the pressure driving member 70 is a hydraulic cylinder. The hydraulic cylinder is driven by hydraulic pressure and can provide a relatively large pressure with better pressure stability to meet the production requirements of the film.

[0047] In some embodiments, the second roller seat 40 is slidably mounted on the frame 10 and includes a limiting structure that cooperates with the frame 10. The limiting structure is configured to limit movement of the second roller seat 40 in a direction perpendicular to the pressure-applying direction of the pressure-driven member 70, thereby ensuring that the second roller seat 40 does not change direction during the pressure-applying process of the pressure-driven member 70.

[0048] The second roller seat 40 may be installed in any manner.

[0049] In some embodiments, the second roller seat 40 is fixed to one end of the telescopic rod of the pressure driving member 70. When the pressure driving member 70 is a hydraulic cylinder, the telescopic rod of the pressure driving member 70 is a piston rod.

[0050] By fixing the second roller seat 40 to one end of the telescopic rod of the pressure-driven component 70, the positions of the second roller seat 40 and the telescopic rod of the pressure-driven component 70 remain relatively fixed, ensuring that during the pressure application of the pressure-driven component 70, the position between the second roller seat 40 and the telescopic rod remains stable and does not change, thereby ensuring the gap size between the first roller 30 and the second roller 50.

[0051] It is understandable that the arrangement of the wedge assembly 61 is not limited.

[0052] In some embodiments, the wedge block assembly 61 includes a first wedge block and a second wedge block that are oppositely disposed, and the second wedge block is fixed to the second roller seat 40 .

[0053] The first wedge block and the second wedge block have wedge surfaces, and the wedge surfaces of the first wedge block and the second wedge block can cooperate with each other. When the first wedge block and the second wedge block are relatively displaced, the overall width of the first wedge block and the second wedge block will increase.

[0054] By fixing the second wedge block to the second roller seat 40, the positions of the second roller seat 40 and the second wedge block remain relatively fixed, ensuring that during the pressure application process of the pressure drive member 70, the position between the second roller seat 40 and the second wedge block is stable and does not change, thereby further ensuring the gap size between the first roller 30 and the second roller 50.

[0055] It is understandable that the specific structure of the gap adjusting device 60 is not limited.

[0056] In some embodiments, the seam adjusting device 60 includes a seam adjusting motor 62, a lead screw and a lead screw nut. The seam adjusting motor 62 is connected to the lead screw drive. The lead screw is arranged perpendicular to the width direction of the wedge block assembly 61. The lead screw nut is sleeved on the lead screw. The first wedge block is connected to the lead screw nut. The seam adjusting motor 62 drives the lead screw to rotate to make the first wedge block rise and fall, thereby adjusting the width of the wedge block assembly 61.

[0057] It can be understood that when the lead screw rotates, the lead screw nut moves along the lead screw, and the first wedge follows along the length of the lead screw, that is, perpendicular to the width of the wedge assembly 61. At this time, the first wedge and the second wedge move relative to each other, thereby adjusting the overall width of the first and second wedges. This changes the spacing between the second roller seat 40 and the first roller seat 20 when the wedge assembly 61, the second roller seat 40, and the first roller seat 20 are in contact. In addition, by cooperating with the lead screw and the lead screw nut to raise and lower the first wedge, the number of turns and pitch of the lead screw can be used to determine the height of the lift, and thus the adjusted width. This allows for relatively accurate control of the lift height of the first wedge.

[0058] The seam adjusting motor 62 can be fixed on the frame 10 , and the lead screw can be rotatably mounted on the frame 10 .

[0059] In some embodiments, the first roller 30 and the second roller 50 are made of a rigid material. Rigid materials only slightly deform or do not deform under external forces, thereby facilitating control of the gap size between the first roller 30 and the second roller 50.

[0060] In some embodiments, the first roller 30 and the second roller 50 are made of iron or steel. The cost of iron or steel is relatively low, which helps to control the overall cost.

[0061] In order to largely avoid air from remaining in the film during the winding process, in some embodiments, the film roll forming device includes a winding shaft 81 , a pressure roller 82 , and a swing arm 83 .

[0062] The reel 81 is used to receive the film wound through the pressure roller 82. The reel 81 is arranged on the frame 10, and the reel 81 can actively rotate to reel the film for storage.

[0063] One end of the swing arm 83 is rotatably arranged on the frame 10, and the other end is a suspended free end, and the pressure roller 82 is arranged on the other end of the swing arm 83, that is, an suspended end. It is understandable that the swing arm 83 has the ability to rotate with the pressure roller 82.

[0064] The swing arm 83 has a torque so that the pressure roller 82 is pressed against the film of the reel 81. Thereby providing pressure so that the film is tensioned, so that the film wound on the reel 81 can be more compact and can discharge air to a large extent.

[0065] It can be understood that the torque causes the swing arm 83 to have a tendency to rotate, thereby providing pressure to act on the membrane.

[0066] The torque may be provided by setting an elastic member, and the torque of the swing arm 83 is provided by elastic deformation of the elastic member.

[0067] The torque can also be provided by the weight of the swing arm 83 and the pressure roller 82. In some embodiments, the swing arm 83 is positioned at one end of the frame 10 above the reel 81 and offset relative to the reel 81 in the direction of gravity. Thus, under the weight of the swing arm 83 and the pressure roller 82, the pressure roller 82 presses against the film on the reel 81.

[0068] In order to make the edge of the film neat, in some embodiments, the film roll forming device includes a trimming shaft 84 and a support shaft 85, with a gap between the trimming shaft 84 and the support shaft 85 for the film to pass through. The trimming shaft 84 has two trimming blades that protrude radially and are spaced apart from each other in the axial direction. The trimming blades abut against the support shaft 85, and the trimming shaft 84 rotates relative to the support shaft 85 so that the trimming blades cut the edge of the film.

[0069] The trimming shaft 84 and the support shaft 85 can both rotate relative to the frame 10. The film enters the gap between the trimming shaft 84 and the support shaft 85, and the trimming blade is pressed against the edge of the film. At the position where the trimming blade abuts the support shaft 85, the film is cut, thereby forming a neat edge.

[0070] It can be understood that the interval between the two cutting edges is the width of the film after cutting.

[0071] In some embodiments, the support shaft 85 is the driving shaft and the trimming shaft 84 is the driven shaft. The trimming shaft 84 abuts against the support shaft 85 due to its own weight, and the two are driven by friction. It is understood that the trimming shaft 84 has a certain amount of weight, so it can cut the edge of the film by its own weight.

[0072] In order to guide the film to flow toward the support shaft 85, a passing roller 88 can be set below the first roller 30 and the second roller 50, and a passing roller 88 can be set below the support shaft 85. After passing through the two passing rollers 88, the film enters the support shaft 85 and the trimming shaft 84, making the overall structure more compact.

[0073] In some embodiments, the film roll forming apparatus includes an electrostatic eliminator 86 , which is used to eliminate static electricity in the film. The electrostatic eliminator 86 is disposed between the trimming shaft 84 and the second nip roller 50 .

[0074] The static eliminator 86 may be an ion blower, which generates ion wind and blows it toward the film to neutralize and eliminate static electricity on the film.

[0075] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. In addition, the embodiments of the present invention and the features of the embodiments can be combined with each other unless there is a conflict.
