Description

Technical Field

[0001] This application relates to the technical field of composite profile cold bending forming machine, and more particularly to a roll forming device for TMP integrated tile composite layer. Background Technology

[0002] In the existing technology, the production process of TMP (hot melt adhesive film) integrated tile composite layer typically uses a single roller structure 101 to roll-form the soft film and the substrate 102 into a cold-bending shape (see reference). Figure 1 However, this structure has the following technical drawbacks:

[0003] 1. The membrane surface is prone to cracking and scratching: Because the roller pressing device is a single-wheel structure, the soft membrane and the roller are in rigid contact during the rolling process, and there is no effective speed adjustment mechanism. Under high-speed operation or uneven membrane tension, the surface of the soft membrane is very prone to scratches, wear, and even cracking, which seriously affects the appearance and performance of the product.

[0004] 2. Poor adaptability of flexible film: Flexible film materials are characterized by high elasticity, strong ductility, and inability to be shaped after molding. Unlike traditional rigid materials such as steel plates, they cannot withstand direct hard pressure. Existing roll forming methods fail to fully consider the material characteristics of flexible film, causing the film material to be easily stretched and deformed during the roll forming process, resulting in unexpected displacement and affecting the composite accuracy.

[0006] To solve the above-mentioned technical problems, this application provides a rolling device for TMP integrated tile composite layers, which adopts the following technical solution:

[0011] In a preferred embodiment, a second pressure sleeve is fitted on the outer ring of the upper bearing structure, and a second groove is provided radially inward on the outer periphery of the second pressure sleeve. A third pressure sleeve is fitted on the outer ring of the lower bearing structure, and a second protrusion is provided on the outer periphery of the third pressure sleeve corresponding to the second groove.

[0016] In a preferred embodiment, two sets of the edge-receiving pressure rollers are symmetrically arranged on both sides of the upper and lower rollers along the axial direction.

[0017] In summary, this application has the following beneficial effects:

[0018] This invention features a bearing structure on the upper and / or lower rollers.

This prevents the film surface from being damaged by friction during the rolling process, resulting in a soft film free of scratches and cracks, with a film surface integrity rate of ≥99%.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0029] The following is in conjunction with the appendix Figure 2-6 This application will be described in further detail.

[0030] This embodiment provides a roll forming device for TMP integrated tile composite layers, used for roll forming the TMP integrated tile composite layer. The TMP integrated tile composite layer is formed by laminating a 1.0mm substrate with 1.0mm thick polymer rolls on both the top and bottom edges using a special process. The polymer rolls are made of TPO or PVC. (See reference...) Figure 6 A polymer roll is attached above and below the substrate to form a TMP composite profile 1.

[0031] The roller pressing device provided in this embodiment includes two sets of rollers 2 arranged vertically. The two sets of rollers 2 are supported on the frame by two rotating shafts 3 arranged vertically opposite each other. Both sets of rollers 2 are horizontal roller structures. The axes of the two sets of rollers 2 are parallel and have a gap. The gap allows the TMP composite profile 1 to pass through, and the TMP composite profile 1 is rolled and cold-bent within the gap.

[0032] refer to Figure 6The TMP composite profile 1 is rolled during the rolling process, including the rolling of the nose structure 11 in the middle of the profile. Since the nose structure 11 is relatively complex, the middle of the profile needs to be rolled multiple times during the rolling process. The soft film will be subjected to uneven tensile force during the rolling process, which will damage the film surface.

[0033] To avoid damaging the film surface during the rolling process, refer to Figures 2-4 In this embodiment, a bearing structure 4 is provided on the upper roller and / or lower roller of the roller group 2 that rolls the nose structure 11. The bearing structure 4 can be set in the middle part of the upper roller and / or lower roller, or the bearing structure 4 can be directly used as the upper roller and / or lower roller. The bearing structure 4 is used to reduce the friction between the roller and the film surface. The bearing structure 4 relies on the friction between the roller and the soft film to achieve differential rolling, which can keep the soft film in a "zero tension" state, avoid the film surface from being damaged by friction during the rolling process, and ensure that the soft film is free of scratches and cracks, with a film surface integrity rate of ≥99%.

[0034] In this embodiment, the bearing structure 4 can be a rolling bearing, a sliding bearing, or other types of bearings. The number and arrangement of these bearings can be adjusted according to actual needs. By adding the bearing structure 4, damage to the film surface during the rolling process can be effectively reduced, thereby improving product quality and yield.

[0035] refer to Figure 6 When rolling the nose structure 11 in the middle of the TMP composite profile 1, it is divided into a first rolling process, a second rolling process and a third rolling process. The first rolling process is used to roll the inner groove structure 111 that is formed simultaneously on both sides of the nose structure 11. The second rolling process is used to roll the nose structure 11 that is raised upward. The third rolling process is used to roll the nose structure 11 to shape it.

[0036] refer to Figure 2 The rolling device for the first rolling process includes two sets of rollers 2, each comprising a first upper roller 21, a first lower roller 22 for rolling the inner groove structure 111, and upper and lower transport rollers that are matched axially. The first upper roller 21 is provided with a bearing structure 4, which is fitted into the middle groove of the first upper roller 21 by interference fit. A first pressure sleeve 41 is fitted on the outer ring of the bearing structure 4. The first pressure sleeve 41 is annular, and two radially outward first protrusions 42 are integrally machined on its outer circumference, with the two first protrusions 42 spaced apart. The first lower roller 22 is provided with two first grooves 221 corresponding to the two first protrusions 42, forming a "convex-concave" pressing cavity. The first protrusions 42 and the first grooves 221 cooperate to roll and form the inner groove structure 111.

[0037] A set of bearing structures 4 is set in the middle section of the first upper roller 21. During the roll pressing and transportation of the TMP composite profile 1, the outer ring of the bearing structure 4 is passively rotated with the linear velocity of the profile and has pure rolling contact with the film surface. This transforms the sliding friction in traditional roll pressing into rolling friction, significantly reducing the coefficient of friction and preventing the film surface from being scratched, hot-melted, or stretched due to sliding and dragging.

[0038] refer to Figure 3 The roller pressing device for the second rolling process includes two sets of rollers 2 for the two sets of rollers in this process, including a second upper roller 23 and a second lower roller 24 for rolling the nose structure 11 upwardly, and upper and lower transport rollers that are matched front and back along the axial direction. The bearing structure 4 is divided into an upper bearing structure 43 and a lower bearing structure 44. The second upper roller 23 directly adopts the upper bearing structure 43, that is, the entire second upper roller 23 is the upper bearing structure 43. The second lower roller 24 is provided with a lower bearing structure 44, which is embedded in the middle section groove of the second lower roller 24 by interference fit.

[0039] The second lower roller 24 has upwardly protruding inclined pressure surfaces 241 on both symmetrical sides of the lower bearing structure 44. The highest edge of the inclined pressure surface 241 is close to the lower bearing structure 44, and a clearance gap 242 is provided between the edge and the lower bearing structure 44. Flat pressure surfaces 243 are provided on both sides of the second lower roller 24 connecting the inclined pressure surfaces 241. Two first upper transport rollers 231 are respectively provided on both sides of the second upper roller 23. A gap is provided between the first upper transport rollers 231 and the flat pressure surfaces 243 on both sides of the second lower roller 24. The first upper transport rollers 231 and the flat pressure surfaces 243 of the second lower roller 24 cooperate to roll and press, forming a roll-pressed transport of the TMP composite profile 1.

[0040] A second pressure sleeve 431 is fitted on the outer ring of the upper bearing structure 43. A second groove 432 with a radial inward direction is integrally machined on the outer circumference of the second pressure sleeve 431. A third pressure sleeve 441 is fitted on the outer ring of the lower bearing structure 44. A second radial protrusion 442 is provided on the outer circumference of the third pressure sleeve 441 corresponding to the second groove 432, forming a "concave-convex" pressing cavity. The second groove 432 and the second protrusion 442 cooperate to precisely constrain the bending of the root of the nose structure 11.

[0041] When the TMP composite profile 1 is rolled through, the middle position of the two inner groove structures 111 is rolled by the second groove 432 and the second protrusion 442. The two sides of the two inner groove structures 111 are rolled upward by the inclined pressing surface 241. Under the bending of the second groove 432, the second protrusion 442 and the inclined pressing surface 241, the inner groove structure 111 is gradually squeezed inward to the clearance gap 242, and finally forms the three-dimensional protrusion of the nose structure 11.

[0042] Through the "double passive rolling" setting of the upper bearing structure 43 and the lower bearing structure 44, the second roller pressing device always changes the relative motion between the film surface and the roller body from sliding to rolling throughout the entire process of forming the nose structure 11: the outer ring of the upper bearing structure 43 rotates synchronously with the TMP composite profile 1, and the outer ring of the lower bearing structure 44 also passively follows the rotation when the second protrusion 442 lifts the profile. The linear speed of the two is adaptive in real time, completely eliminating sliding shear; at the same time, the "progressive material receiving space" formed by the inclined pressing surface 241 and the clearance gap 242 allows the inner groove structure 111 to be squeezed into the clearance gap 242 while bending upward, realizing tension-free and tear-free three-dimensional forming, thereby ensuring that the root radius, height and surface quality of the nose structure 11 meet the finished product requirements in one go.

[0043] refer to Figure 4 The roller pressing device for the third rolling process includes a third upper roller 25 and a third lower roller 26 for shaping the nose structure 11, as well as upper and lower transport rollers that are matched front and back along the axial direction. The third upper roller 25 and the third lower roller 26 are the bearing structure 4 as a whole, forming an integral passively rotatable bearing rolling structure. At the same time, two second upper transport rollers 251 and two second lower transport rollers 261 are respectively arranged at intervals on both sides of the third upper roller 25 and the third lower roller 26.

[0044] Among them, a fourth pressure sleeve 252 is fitted on the outer ring of the third upper roller 25, and a fifth pressure sleeve 262 is fitted on the outer ring of the third lower roller 26. A radial third groove 253 is integrally machined on the outer circumference of the fourth pressure sleeve 252. The third groove 253 is set at the root of the nose structure 11. The fifth pressure sleeve 262 is provided with a third protrusion 263 corresponding to the third groove 253, forming a "concave-convex" closed cold pressing cavity, which is used to finally press the nose structure 11 tightly so that it will not spring back after discharge.

[0045] Because polymer roll materials are highly elastic and ductile, after roll forming, the edges cannot be effectively shaped due to elastic recoil, often resulting in excess material overflowing. Since polymer roll materials lack cutting capabilities, excess material cannot be removed using conventional cutting methods after forming, leading to uneven edges and dimensional instability, affecting subsequent assembly and use. Therefore, in this embodiment, a set of edge-reducing rollers is also provided in the roll forming device of the third roll forming process for rolling the raised ribs 12 of the TMP composite profile 1. The raised ribs 12 of the TMP composite profile 1 are referenced... Figure 6 The raised rib 12 can fold away excess material, resulting in neat edges after molding and eliminating the need for cutting.

[0046] refer to Figure 5In the roller group 2, the edge-retracting pressure roller group includes an upper pressure roller group 27 and a lower pressure roller group 28 symmetrically arranged on both sides of the second upper conveying roller 251 and the two second lower conveying rollers 261 along the axial direction. The upper pressure roller group 27 and the lower pressure roller group 28 on each side include two upper pressure rollers and two lower pressure rollers, and the outer periphery contour of the two upper pressure rollers and the two lower pressure rollers is set as a stepped structure 29. The stepped structure 29 of the two groups of pressure rollers is in opposite directions. The pressing surface of the upper pressure roller group 27 and the stepped structure 29 of the lower pressure roller group 28 cooperate with each other. The raised rib 12 is pressed by the stepped structure 29, and the uncut excess material is folded to form the raised rib 12, so as to achieve neat edges, no cutting required, and stable dimensions.

[0047] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
