Description

Technical Field

[0001] The utility model belongs to the technical field of film rolling, and in particular relates to a film rolling and flattening device. Background Art

[0002] As plastic products enter people's lives and various types of films have more and more functions and application scenarios, the market demand for films is very large. In the early stage of film production, plastic granular materials are made into various types of films through various processing equipment, and the stretched films are rolled onto reels by winders, so that they can be sent to the next production site to be made into various required products. Due to the soft and thin nature of the film, wrinkles are prone to appear during the winding process, resulting in waste film rolls and a lower quality pass rate for the finished film rolls. If it is processed again, it will increase costs.

[0003] At present, the flattening roller of the film winder is located before the follow-up roller, and is usually dominated by banana flattening rollers. Some production lines also use edge flattening rollers. When producing thinner films, the follow-up roller contacts the film roll and plays a role in exhaust and wrinkle prevention during the winding process, because the film needs to have a certain tension during the winding process, and the more uniform the tensile tension value of the film, the flatter the film is on the core. However, after the film leaves the roller surface, if the film width is too large, the film is in a larger space and is subject to a certain traction force. At this time, the rigidity of the film is poor, and many wrinkles will appear on the surface. Moreover, the longer the spatial distance, the greater the traction force, and the more wrinkles. Therefore, for large film winders with wider widths and greater film stretchability, a set of flattening devices are needed on both sides of the film. However, conventional edge flattening devices cannot stably meet the winding flatness of wider, thinner and softer films.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0010] Furthermore, the adjustment assembly includes a sliding ear plate, which is fixedly connected to the second hanging ear. The outer surface of the connecting plate is provided with a sliding groove and a screw hole. The second hanging ear is slidably connected to the inside of the sliding groove. The outer surface of the sliding ear plate is threadedly connected with a bolt, and the bolt passes through the sliding ear plate and extends to the inside of the screw hole.

[0011] Furthermore, a sliding component is arranged on the top of the base, the fixing seat is fixedly connected to the top of the sliding component, and an auxiliary component is arranged on the outer surface of the connecting plate.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model connects the flattening assembly and the follow-up roller. The second rubber roller in the flattening assembly is always located on the outside of the follow-up roller during the winding process. The second rubber roller presses the edge of the film tightly against the follow-up roller. During the winding process, the high-speed movement of the film drives the air on the surface of the film to move and enter between the film and the follow-up roller. At this time, since the second rubber roller always presses the edge of the film against the follow-up roller, an air lubrication layer with a certain pressure is generated between the follow-up roller and the film. Under the action of compressed air, the film here is flattened. When the follow-up roller applies a certain pressure to the mother roll, the air with a certain pressure value here is always maintained between the film and the follow-up roller to flatten the film. Under the action of compressed air, the thinner and softer film is flattened so that the film is flatly rolled on the winding core.

[0016] 2. The utility model releases the limit fixation of the sliding ear plate and pushes it to drive the second ear to move through the connection between the slide groove and the second ear. The second ear stretches the spring so that the spring applies different degrees of pulling force to the connecting plate. The second rubber roller on the connecting plate can apply different pressing forces to the film. The staff can adjust the position of the spring according to the needs of use, which is more flexible to use.

[0027] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0029] See also Figure 1-Figure 6 As shown, the utility model is a film winding and flattening device, including a base 1, a flattening component 2 is arranged on the top of the base 1, a winding and pulling component 3 is arranged on the outer surface of the flattening component 2, an adjusting component 4 is arranged on the outer surface of the winding and pulling component 3, a following roller 5 is arranged on the bottom of the flattening component 2, a winding core 6 is arranged on the outer surface of the following roller 5, the winding core 6 is used for winding the film, the flattening component 2 is used for pressing the edge of the film, the winding and pulling component 3 is used for tightening the flattening component 2, and the adjusting component 4 is used for adjusting the position of the winding and pulling component 3.

[0030] The film passes through the flattening component 2 and enters between the follow-up roller 5 and the winding core 6, and is wound around the outer surface of the winding core 6. When the winding core 6 begins to be wound, the tensioning component 3 tightens the flattening component 2 to make it press against the surface of the follow-up roller 5, so that the edge of the film is pressed to ensure the flatness of the film on the winding core 6. When the model of the film wound on the winding core 6 changes, the limiting fixation of the tensioning component 3 by the adjustment component 4 is released, so that the tensioning component 3 slides on the flattening component 2 for position adjustment. The tensioning component 3 applies different degrees of tension to the flattening component 2, which can change the pressure between the flattening component 2, the follow-up roller 5 and the film.

[0031] The utility model adjusts the connection between the adjustment component 4 and the retracting component 3, and the adjustment component 4 drives the retracting component 3 to move, thereby changing the position of the retracting component 3 on the flattening component 2, so that the retracting component 3 presents different lengths. At this time, the retracting component 3 can apply different degrees of pulling force to the flattening component 2, and the distance between the flattening component 2, the following roller 5 and the film, as well as the pressing force on the film are changed accordingly. The staff can make adjustments by themselves according to actual needs, and it is more flexible to use.

[0032] In one embodiment, for the above-mentioned flattening component 2, the flattening component 2 includes a fixed seat 201, the top of the fixed seat 201 is fixedly connected to a swing cylinder 202, the output shaft of the swing cylinder 202 is fixedly connected to a swing arm 203, the outer surface of the fixed seat 201 is rotatably connected to a first rubber roller 204, the outer surface of the swing arm 203 is rotatably connected to an aluminum roller 205 and a connecting plate 206, the outer surface of the connecting plate 206 is rotatably connected to a second rubber roller 207, and the second rubber roller 207 is located above the following roller 5.

[0033] In one embodiment, for the above-mentioned retracting and pulling component 3, the retracting and pulling component 3 includes a first hanging ear 301, the first hanging ear 301 is fixedly connected to the swing arm 203, the outer surface of the connecting plate 206 is slidably connected to the second hanging ear 303, and a spring 302 is hung between the first hanging ear 301 and the second hanging ear 303.

[0034] The swing cylinder 202 on the fixed seat 201 is started, and the swing cylinder 202 drives the swing arm 203 to rotate. The swing arm 203 drives the connecting plate 206 to move so that the second rubber roller 207 is against the follow-up roller 5, and the edge of the film is pressed for the first time. The swing arm 203 continues to rotate downward. At this time, the second rubber roller 207 remains stationary, and relative rotation occurs between the connecting plate 206 and the swing arm 203. The distance between the second hanging ear 303 on the connecting plate 206 and the first hanging ear 301 increases, and the second hanging ear 303 stretches the spring 302. The spring 302 generates a reverse pulling force to pull the connecting plate 206. The swing arm 203 simultaneously drives the aluminum roller 205 and approaches the first rubber roller Wheel 204, aluminum roller 205 and first rubber roller 204 cooperate to realize the compression of the edge of the film, and the second rubber roller 207 presses the edge of the film against the follow roller 5. When the film is rolled up at high speed, a part of the gas is driven to move along the running direction of the film, thereby forming a gas lubrication layer between the film and the follow roller 5. Due to the compressibility of the gas, the gas here has a certain pressure, which flattens the film. At this time, since the edge of the film is pressed by the second rubber roller 207, the air pressure here is maintained at a certain value, ensuring that the film and the follow roller 5 can slide relative to each other, and the film is flat and wrinkle-free when it contacts the winding core 6, ensuring the flatness of the film after rolling.

[0035] In one embodiment, for the above-mentioned adjustment component 4, the adjustment component 4 includes a sliding ear plate 401, the sliding ear plate 401 is fixedly connected to the second hanging ear 303, the outer surface of the connecting plate 206 is provided with a sliding groove 402 and a screw hole 403, the second hanging ear 303 is slidably connected to the inside of the sliding groove 402, and the outer surface of the sliding ear plate 401 is threadedly connected with a bolt 404, and the bolt 404 passes through the sliding ear plate 401 and extends to the inside of the screw hole 403.

[0036] Separate the bolt 404 from the screw hole 403 so that the bolt 404 releases the limit fixation on the sliding ear plate 401, push the sliding ear plate 401 to drive the second hanging ear 303 to move along the slide groove 402, so that the second hanging ear 303 drives the spring 302 to expand and contract, and the spring 302 applies different degrees of tension to the connecting plate 206, thereby changing the pressing force of the second rubber roller 207 on the connecting plate 206 on the film. After the adjustment is completed, connect the bolt 404 to the screw hole 403 and fix the sliding ear plate 401. The staff can adjust it by themselves according to the needs, and it is more flexible to use.

[0037] In one embodiment, for the above-mentioned base 1 , a sliding component 7 is disposed on the top of the base 1 , the fixing seat 201 is fixedly connected to the top of the sliding component 7 , and an auxiliary component 8 is disposed on the outer surface of the connecting plate 206 .

[0038] In one embodiment, for the above-mentioned sliding component 7, the sliding component 7 includes a first sliding rail 701, the first sliding rail 701 is fixedly connected to the base 1, the first sliding rail 701 is internally slidably connected to a first slider 702, the top of the first slider 702 is fixedly connected to a second sliding rail 703, the outer surface of the second sliding rail 703 is slidably connected to a second slider 704, the second slider 704 is fixedly connected to the fixed seat 201, and the sliding directions of the second slider 704 and the first slider 702 are perpendicular to each other.

[0039] When the first slider 702 slides along the first slide rail 701, the first slider 702 drives the second slide rail 703 and the fixed seat 201 to move closer to or away from the following roller 5. When the second slider 704 moves on the second slide rail 703, the second slider 704 drives the fixed seat 201 to move along the axial direction of the following roller 5.

[0040] In one embodiment, for the auxiliary component 8 , the auxiliary component 8 includes a scale line 801 , which is fixedly connected to the outer surface of the connecting plate 206 , and an indicator arrow 802 is fixedly connected to the outer surface of the sliding ear plate 401 .

[0041] The sliding ear plate 401 drives the indicating arrow 802 to move, and the indicating arrow 802 points to different scale lines 801, so that the staff can know the current position of the sliding ear plate 401 more intuitively.

[0042] According to the above technical solution, 1. through the connection between the flattening assembly 2 and the follow-up roller 5, the second rubber roller 207 in the flattening assembly 2 is always located outside the follow-up roller 5 during the winding process, and the second rubber roller 207 presses the edge of the film tightly against the follow-up roller 5. During the winding process, the high-speed movement of the film drives the air on the surface of the film to move and enter between the film and the follow-up roller. At this time, since the second rubber roller 207 always presses the edge of the film against the follow-up roller 5, an air lubrication layer with a certain pressure is generated between the follow-up roller 5 and the film. Under the action of compressed air, the film here is flattened. When the follow-up roller 5 applies a certain pressure to the mother roll, the air with a certain pressure value here is always maintained between the film and the follow-up roller 5 to flatten the film. Under the action of compressed air, the thinner and softer film is flattened, so that the film is flatly rolled on the winding core 6. 2. Through the connection between the slide groove 402 and the second hanging ear 303, the limit fixation of the sliding ear plate 401 is released and it is pushed to drive the second hanging ear 303 to move. The second hanging ear 303 stretches the spring 302, so that the spring 302 applies different degrees of pulling force to the connecting plate 206. The second rubber roller 207 on the connecting plate 206 can apply different pressing forces to the film. The staff can adjust the position of the spring 302 according to the needs of use, which is more flexible to use.
