Description

Technical Field

[0001] This utility model relates to the field of winding device correction technology, and in particular to a winding correction device for film winding. Background Technology

[0002] In the film production process, in order to make the material wound on the take-up roller more even, Chinese Patent Application No. CN201520648348.1 discloses an adjustment device for the installation device of the take-up shaft of a slitting machine. This adjustment device applies pulling and pushing forces to the take-up shaft support plate through tension screws and push screws, thereby adjusting and fixing the position of the take-up shaft support plate, and thus achieving the effect of adjusting the parallelism between the take-up shaft and the transmission roller.

[0003] Although the aforementioned adjustment device can reduce vibration during the winding process of the take-up shaft to reduce the material offset during winding, the film inevitably shifts when it moves in the take-up machine, which will still cause the material on the take-up shaft to shift. Utility Model Content

[0004] The purpose of this invention is to provide a film winding correction device, which aims to solve the problem that the material is prone to deviation during winding in existing small winding devices.

[0005] To achieve the above objectives, this utility model provides a film winding correction device, including a correction roller. The correction roller includes a roller body with multiple sets of grooves evenly arranged on the roller body. Each set of grooves is equipped with a correction plate, which can slide in the groove. A traction rod is fixedly installed on the correction plate, and ball bearings are installed at both ends of the traction rod. Adjustment plates are provided at both ends of the correction roller. The adjustment plates are installed on the roller body through self-aligning bearings, and the ball bearings abut against the adjustment plates. The adjustment plates on both sides are connected by a linkage shaft. Correction driving components are also provided on both sides of the correction roller. The correction driving components are connected to the adjustment plates and drive the correction plates to slide in the grooves through the adjustment plates.

[0006] Furthermore, the roller body is provided with a limit groove, and the correction plate is provided with a limit strip, which can slide in the limit groove.

[0007] Furthermore, both the limiting groove and the sliding groove are equipped with oil storage tanks.

[0008] Furthermore, eight sets of sliding grooves and eight sets of limiting grooves are evenly distributed on the main body of the roller, and the sliding grooves and limiting grooves are arranged alternately on the main body of the roller; a set of limiting strips is provided on both sides of the correction plate, and the width of the limiting strips is equal to half the width of the limiting grooves.

[0009] Furthermore, mounting seats are provided at both ends of the roller body, and the mounting seats are provided with sliding holes that correspond one-to-one with the traction rods; a reset elastic element is fitted on the traction rod, with one end of the reset elastic element abutting against the mounting seat and the other end abutting against the correction plate.

[0010] Furthermore, a support is installed on the mounting base, and a bearing is provided between the support and the mounting base. The correction drive component is fixedly installed on the support.

[0011] Furthermore, a corrugated dust cover is fitted onto the main body of the roller, with one end of the corrugated dust cover abutting against the alignment plate and the other end abutting against the mounting base.

[0012] Furthermore, a soft rubber layer is provided on the outer side of the correction plate, and extension portions are provided at both ends of the soft rubber layer.

[0013] Furthermore, a perforated layer is provided between the correction plate and the soft rubber layer.

[0014] The present invention provides a film winding correction device. Compared with the prior art, when the detection device on the winding machine detects that the film has deviated, the correction drive can drive the adjustment plate to deflect. The deflected adjustment plate drives the correction plate to slide laterally on the roller body through the traction rod, thereby correcting the deviation of the film during the movement and making the material on the winding roller more uniform.

[0033] The present invention will be described in detail below with reference to specific embodiments.

[0034] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0035] like Figures 1 to 11As shown, this utility model provides a film winding correction device, including a correction roller 1, which includes a roller body 2. The roller body 2 is evenly provided with multiple sets of sliding grooves 20. Each set of sliding grooves 20 is equipped with a set of correction plates 3, which can slide in the sliding grooves 20. A traction rod 30 is fixedly installed on the correction plate 3, and a ball bearing seat 31 is installed at both ends of the traction rod 30. An adjustment plate 4 is provided at both ends of the correction roller 1. The adjustment plate 4 is installed on the roller body 2 through a self-aligning bearing 42. The ball bearing seat 31 abuts against the adjustment plate 4. The two adjustment plates 4 are connected by a linkage shaft 40. Correction driving components 41 are also provided on both sides of the correction roller 1. The correction driving components 41 are connected to the adjustment plates 4. The correction driving components 41 drive the correction plates 3 to slide in the sliding grooves 20 through the adjustment plates 4.

[0036] With the above design, when the detection device on the winding machine detects a deviation in the wound film, the detection device measures the deviation direction and distance. The correction drive 41 extends or retracts according to the signal from the detection device. The extended or retracted correction drive 41 causes the adjusting plate 4 to swing on the self-aligning bearing 42. The swinging adjusting plate 4 pushes the traction rod 30, causing the correction plate 3 to slide a distance in the slide groove 20, thus correcting the deviation of the film. Under the action of the linkage shaft 40, the adjusting plates 4 on both sides can swing synchronously. Simultaneously, the linkage shaft 40 ensures that the swing angles of the adjusting plates 4 on both sides are consistent. The ball bearing seats 31 at both ends of the traction rod 30 ensure that the adjusting plate 4 remains in contact with the traction rod 30 during the rotation of the roller body 2. Under the action of the balls in the ball bearing seats 31, the ball bearing seats 31 can slide smoothly on the adjusting plate 4.

[0037] In this embodiment, a limiting groove 21 is provided on the roller body 2, and a limiting strip 36 is provided on the correction plate 3. The limiting strip 36 can slide in the limiting groove 21.

[0038] Through the above design scheme, the limiting groove 21 can limit the swing angle of the limiting strip 36, and prevent the correction plate 3 from swinging left and right during the movement, which would affect the winding accuracy of the film.

[0039] In this embodiment, both the limiting groove 21 and the sliding groove 20 are provided with oil storage grooves 22, which can store lubricating grease to ensure that the correction plate 3 can slide smoothly on the roller body 2.

[0040] Through the above design scheme, the grease in the oil storage tank 22 can effectively reduce the friction between the straightening plate 3 and the roller body 2, making the sliding of the straightening plate 3 smoother.

[0041] In this embodiment, eight sets of sliding grooves 20 and eight sets of limiting grooves 21 are evenly distributed on the roller body 2, and the sliding grooves 20 and limiting grooves 21 are arranged alternately on the roller body 2; a set of limiting strips 36 are provided on both sides of the correction plate 3, and the width of the limiting strips 36 is equal to half the width of the limiting grooves 21.

[0042] With the above design scheme, eight sets of correction plates 3 evenly occupy the surface of the roller body 2. The limiting strips 36 on both sides of the correction plate 3 can lock the two sets of limiting grooves 21, and the limiting strips 36 of two different correction plates 3 can be placed in a single limiting groove 21, so as to avoid large deviations between different correction plates 3 that affect the winding accuracy.

[0043] In this embodiment, the roller body 2 is provided with mounting seats 5 at both ends, and the mounting seats 5 are provided with sliding holes 52 corresponding to the traction rods 30; the traction rods 30 are fitted with reset elastic members 32, one end of the reset elastic members 32 abuts against the mounting seats 5, and the other end abuts against the correction plate 3.

[0044] Through the above design scheme, the sliding hole 52 can provide support for the traction rod 30, preventing the traction rod 30 from extending too far and bending during the correction process, which would affect the correction effect; the reset elastic element 32 on the traction rod 30 can automatically return the correction plate 3 to the center. After the correction operation, the correction drive 41 is unlocked, and the correction plate 3 automatically slides to the center of the roller body 2 under the action of the reset elastic element 32, ensuring the stable transmission of the film during normal operation.

[0045] In this embodiment, a support 50 is installed on the mounting base 5, and a bearing is provided between the support 50 and the mounting base 5. The correction drive component 41 is fixedly installed on the support 50.

[0046] With the above design scheme, the support 50 can easily install the correction roller 1 on the winding machine.

[0047] In this embodiment, a corrugated dust cover 51 is fitted onto the roller body 2. One end of the corrugated dust cover 51 abuts against the correction plate 3, and the other end abuts against the mounting base 5.

[0048] Through the above design scheme, the corrugated dust cover 51 can cover the part of the roller body 2 exposed to the air, reducing dust and other impurities from drifting into the slide groove 20 or the limiting groove 21 and affecting the service life of the lubricating grease.

[0049] In this embodiment, a soft rubber layer 33 is provided on the outer side of the correction plate 3, and extension portions 34 are provided at both ends of the soft rubber layer 33.

[0050] In this embodiment, a perforated layer 35 is provided between the correction plate 3 and the soft adhesive layer 33.

[0051] Through the above design scheme, the soft rubber layer 33 on the outside of the correction plate 3 is made of soft rubber material. The soft rubber layer 33 can protect the film and avoid damage to the film. The extension portion 34 on the soft rubber layer 33 can increase the surface area, so that the correction plate 3 has a larger working range. The hollow layer 35 in the correction plate 3 can reduce the volume of the correction plate 3. At the same time, some materials such as sponge can be filled in the hollow layer 35 to prevent lubricating oil from seeping out from the gap between the two sets of correction plates 3 under the action of centrifugal force, which would affect the quality of the film.

[0052] In this embodiment, the correction drive 41 can be a pneumatic cylinder or a hydraulic cylinder, and the reset elastic element 32 is preferably a pressure spring.

[0053] The present invention provides a film winding correction device. Compared with the prior art, when the detection device on the winding machine detects that the film has deviated, the correction drive 41 can drive the adjustment plate 4 to deflect. The deflected adjustment plate 4 drives the correction plate 3 to slide laterally on the roller body 2 through the traction rod 30, thereby correcting the deviation of the film during the movement, so that the material on the winding roller can be more neat.

[0054] Where there is no conflict, the above embodiments and features can be combined with each other.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
