Abstract
Description
Technical Field
[0001] This utility model relates to a flattening roller and a winding device including the flattening roller. Background Technology
[0002] After the wide film is slit, two narrow films are wound up simultaneously, which can meet the production needs of narrow films and improve the production efficiency of narrow films. However, the existing flattening roller can only flatten a single film and needs to be set before slitting. This makes it impossible to eliminate the wrinkles caused by slitting, which affects the quality of winding. Utility Model Content
[0003] In view of the technical problems existing in the background art, the present invention aims to provide a flattening roller and a winding device including the flattening roller. The roller body is designed to consist of a first support ring, a second support ring and a support strip, and a reserved installation space is provided for the second support ring of another roller body. The addition of the roller body can meet the needs of flattening multiple narrow films.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This flattening roller includes a mounting shaft and a roller body. The roller body is sleeved on the mounting shaft. The roller body includes a first support ring, a support strip, and a second support ring. The diameter of the first support ring is larger than the diameter of the second support ring. An installation space is formed between the first support ring and the second support ring for accommodating the second support ring of another roller body. A support strip is connected between the first support ring and the second support ring. A plurality of support strips are circumferentially spaced along the mounting shaft, and a gap is formed between the support strips for the support strip of another roller body to pass through.
[0005] In this scheme, the diameter difference between the first support ring and the second support ring causes the support strip to tilt axially relative to the mounting shaft. The tension generated by gravity on the film on the support strip is flattened. The installation space is reserved for the second support ring of another roller. The addition of rollers can meet the needs of flattening multiple narrow films.
[0006] Preferably, there are at least two rollers, with the second support ring of one roller located in the mounting space of the other roller. The rollers are axially movable and adjustable along the mounting axis, and the support bars of the two rollers are staggered circumferentially along the mounting axis.
[0007] In this scheme, after adding the roller, the axial movement adjustment roller can adapt to the film width variation of a single film.
[0008] Preferably, two second support rings are respectively disposed on both sides of the first support ring along the axial direction of the mounting shaft.
[0009] In this design, the rollers are integrated, and tension is generated on both sides of the film, causing it to flatten out from the middle to both sides.
[0010] Preferably, the second support ring is provided with a through groove for the support bar of the other roller to be inserted.
[0011] In this design, when the membrane width is adjusted to the maximum, the second support ring will not affect the setting of the support strip, and the inclination of the support strip relative to the mounting axis will not be too steep.
[0012] Preferably, bearings are provided between the first support ring and the mounting shaft, and between the second support ring and the mounting shaft.
[0013] In this design, the bearing reduces the coefficient of friction between the mounting shaft and the corresponding support ring.
[0014] Preferably, the support bar is detachable.
[0015] This design facilitates the assembly and disassembly of the rollers.
[0016] Preferably, both the outer periphery of the first support ring and the outer periphery of the second support ring are provided with mounting grooves for mounting the support strip.
[0017] This design facilitates the assembly and disassembly of the rollers.
[0018] Preferably, both the first support ring and the second support ring are provided with stepped holes, the smaller diameter portion of which is for the mounting shaft to pass through, and the larger diameter portion of which is for the bearing to be accommodated.
[0019] In this design, the bearing can axially limit the first and second support rings.
[0020] This type of winding equipment includes a winding mechanism, which includes a first winding shaft and further includes the aforementioned flattening roller. The winding mechanism is connected to the flattening roller.
[0021] In this scheme, the winding mechanism winds up the film after it has been flattened by the flattening roller.
[0022] Preferably, it further includes a support column, which is hinged to the lifting seat with the hinge axis extending in the left-right direction. The lifting seat is provided with a feeding cylinder, and a hinge is provided between the feeding cylinder and the support column. The hinge is hinged to the support column with the hinge axis extending in the left-right direction. The lifting seat is raised and lowered. The winding mechanism includes a second winding shaft that cooperates with the first winding shaft. The second winding shaft and the flattening roller are respectively provided on the front and rear sides of the first winding shaft. The top end of the flattening roller is lower than the top end of the first winding shaft. The support column is located above the flattening roller.
[0023] In this scheme, the top of the flattening roller is lower than the top of the first take-up shaft, leaving enough space for the lifting and lowering of the support shaft table to ensure that the material shaft supported by the support shaft table is reliably tilted between the first take-up shaft and the second take-up shaft.
[0024] The beneficial effects of this invention are as follows: the diameter difference between the first and second support rings causes the support strip to tilt axially relative to the mounting shaft. The tension generated by gravity on the film on the support strip flattens it out. A reserved mounting space is provided for the second support ring of another roller, and the addition of a roller accommodates the need to flatten multiple narrow films. Therefore, this invention has substantial features and advancements compared to existing technologies. Attached Figure Description

[0036] See appendix Figure 1-4 In this embodiment, a flattening roller includes a mounting shaft 1 and a roller body 2. The roller body 2 is sleeved on the mounting shaft 1. The roller body 2 includes a first support ring 3, a support bar 5, and a second support ring 4. Bearings 8 are provided between the first support ring 3 and the mounting shaft 1, and between the second support ring 4 and the mounting shaft 1. Both the first support ring 3 and the second support ring 4 are provided with stepped holes 6. The smaller diameter portion of the stepped hole 6 is for the mounting shaft 1 to pass through, and the larger diameter portion of the stepped hole 6 is for the bearings 8 to be accommodated. The diameter of the first support ring 3 is larger than the diameter of the second support ring 4. Two second support rings 4 are respectively arranged on both sides of the first support ring 3 along the axial direction of the mounting shaft 1. An installation space is formed between the first support ring 3 and the second support ring 4 for accommodating the second support ring 4 of another roller body 2.
[0037] A support bar 5 is connected between the first support ring 3 and the second support ring 4. The support bar 5 is detachable. The outer periphery of the first support ring 3 and the outer periphery of the second support ring 4 are provided with mounting grooves 9 for mounting the support bar 5. Multiple support bars 5 are arranged circumferentially along the mounting shaft 1. A gap is formed between the support bars 5 for the support bar 5 of another roller 2 to pass through. The second support ring 4 is provided with a through groove 7 for the support bar 5 of another roller 2 to be embedded.
[0038] There are at least two roller bodies 2. The second support ring 4 of one roller body 2 is located in the installation space of the other roller body 2. The roller body 2 is axially movable and adjustable along the mounting shaft 1. The support bars 5 of the two roller bodies 2 are staggered along the mounting shaft 1 in a circumferential manner.
[0039] In this embodiment, during assembly, the first support ring 3 and the second support ring 4 are first sequentially fitted onto the mounting shaft 1, and then the support strip 5 is connected. When adding the roller body 2, the second support ring 4 and the first support ring 3 are fitted onto one end of the mounting shaft 1, and the support strip 5 of the already formed roller body 2 is connected to the newly fitted second support ring 4. The independent second support ring 4 serves as part of the new roller body 2, forming a nested relationship between the two roller bodies 2. Taking two flattened sheets as an example, a single wide film is cut in the middle to form two narrow films, and the dividing line corresponds to the two rollers. At the junction of the support strips 5 and the two films, when the film width changes, one or two rollers 2 move axially, and the adjacent second support rings 4 move closer or separate. The distance from the junction to the first support ring 3 changes. When removing the rollers 2, first remove the support strips 5, then connect the support strips 5 of the other rollers 2 to the independent second support ring 4, and remove the outermost second support ring 4 and the first support ring 3. When switching from multi-sheet winding to single-sheet winding, remove the excess rollers 2 and adjust the distance between the first support ring 3 and the second support ring 4.
[0040] In other alternative embodiments, the roller body 2 can be designed in a split manner, with the first support ring 3, the second support ring 4 and the support bar 5 forming the roller body 2. The two parts of the roller body 2 are attached to each other or spaced apart to form a complete whole.
[0041] See appendix Figure 5-6 In one embodiment of this invention, a winding device includes a winding mechanism 10 and a support shaft 13. The support shaft 13 is hinged to a lifting seat 14 with the hinge shaft extending in the left-right direction. The lifting seat 14 is provided with a feeding cylinder 15. A hinge member 16 is provided between the feeding cylinder 15 and the support shaft 13. The hinge member 16 is hinged to the support shaft 13 with the hinge shaft extending in the left-right direction. The lifting seat 14 is raised and lowered. The winding mechanism 10 includes a first winding shaft 11 and a second winding shaft 17.
[0042] The system also includes the aforementioned flattening roller 12. The winding mechanism 10 is connected to the flattening roller 12. The second winding shaft 17 and the flattening roller 12 are respectively located on the front and rear sides of the first winding shaft 11. The top of the flattening roller 12 is lower than the top of the first winding shaft 11. The support shaft 13 is located above the flattening roller 12.
[0043] In this embodiment, the first take-up shaft 11 and the second take-up shaft 17 cooperate to take up the film using the weight of the material shaft. The support shaft 13 rises to obtain a new material shaft, and the support shaft 13 falls and the unloading cylinder 15 drives the support shaft 13 to rotate relative to the lifting seat 14 to tilt the material shaft between the first take-up shaft 11 and the second take-up shaft 17.
[0044] The lifting seat 14 is driven to lift by a cylinder. The front and rear areas of the end of the support shaft 13 are hinged to the lifting seat 14 and the hinge 16, respectively, so that the unloading cylinder 15 can drive the support shaft 13 to rotate in the front and rear direction around the hinge axis connected to the lifting seat 14, tilting the material shaft out. On this basis, a T-shaped hinge 16 can also be set. The hinge 16 forms a hinge relationship with both the support shaft 13 and the output shaft of the unloading cylinder 15. The lifting seat 14 and the support shaft 13 also form a T-shaped hinge relationship. The asynchronous lifting of the left and right lifting seats 14 can make the support shaft 13 tilt in the left and right direction, which is used to fill the material shaft with weight-added components such as balls and self-weight columns by their own weight. The T-shaped hinge 16 and the support shaft 13 are in sliding fit to adapt to the spacing changes caused by asynchronous lifting. Clamping plates are also set in the support shaft groove of the support shaft 13 and the winding mechanism 10 to prevent the weight-added components from falling off the material shaft. A set of winding shafts can also be set for pre-winding.
[0045] In other alternative implementations, the flattening roller 12 can be used for active winding.
[0046] The above description represents the preferred embodiment of this utility model. It should be noted that the protection scope of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these modifications and substitutions are also considered to be within the protection scope of this utility model.
