Description

Technical Field

[0001] The present invention relates to the technical field of label composite production, and in particular to a roll material continuous folding composite production device and method. Background Art

[0002] As flexible film materials are widely used in papermaking, printing, textile and flexible electronics manufacturing industries, flexible film composite folding layers have received a lot of attention. Generally, the composite film layer may be paper, polymer material (such as PET) or metal (such as aluminum foil), and may be in the form of a roll or sheet. For flexible film composite folding layers, there are both composites between flexible coils and composites between coils and folding layers. The former composite can usually be achieved by rolling or flat pressing, and the process is relatively simple; the latter may involve the bending, composite transportation of flexible coils, which requires not only the transfer, stacking and lamination of materials, but also usually requires cutting, unloading and other processes, so the process is relatively complicated.

[0003] The process of compounding the flexible film with the folding layer under the condition of winding and conveying is relatively complicated, and the production process from raw materials to finished products faces many difficulties. First, the folded composite material may be fragile, loose, and not resistant to bending; second, the flexible film layer itself is often a multi-layer structure with cross-sectional changes. Under the action of conveying tension fluctuations, it is easy to elastically deform, and then wrinkle, deviation and other problems will occur; third, the flexible film and other composite materials are heterogeneous materials. When they are stacked on each other under a certain temperature and pressure environment, internal stress may exist due to uneven deformation; finally, the folded film layer usually needs to be cut into finished products, and the remaining film frame waste makes it difficult to transport stably. There are difficulties in the composite process of composite materials and flexible film folding layers, such as stable tension control, composite shaking deviation, and precise positioning; if the material needs to be folded twice and compounded with the flexible filling layer at the same time, there is also the problem of mutual alignment between the materials; similar finished product cutting processes also face alignment problems; therefore, the entire process is difficult to implement.

[0004] Currently, there are already applications for equipment for laminating composite of dissimilar materials, but there are fewer equipment for folding and laminating, especially fewer equipment for folding and laminating filling materials and flexible films that can solve the above-mentioned problems. The patent document with the publication number CN96116314.3 discloses a high-strength fireproof laminated board, its manufacturing process method and pipeline equipment. This invention mainly laminates an adhesive layer and two upper and lower fiberglass layers, and completes the process steps of raw material stirring and melting, auxiliary materials, rolling and curing, demolding, and edge trimming. However, the intermediate base material is not flexible, and there are no deformation problems such as wrinkles and deviation. In addition, the patent document with the publication number CN02813566.0 discloses a separator for a fuel cell and a lamination method and equipment for a membrane and an electrode assembly. However, its focus is on using vacuum adsorption to correct the warping of the separator, and at the same time uses a relatively thick separator as the substrate, and does not solve problems such as precise alignment of the sheet and the flexible film and lamination under hot pressing. Summary of the Invention

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] As Figure 1 shown, a continuous coil folding and composite production equipment includes an equipment main body 1. Along the material conveying direction of the equipment main body 1, a first set of composite rollers 3, a second set of composite rollers 4, a third set of composite rollers 5, a supporting material feeding shaft 6, supporting rollers 7, a folding unit 8, a fourth set of composite rollers 9, a die-cutting knife shaft 10, a finished product receiving and supporting shaft 11 and a finished product receiving shaft 12 are sequentially arranged.

[0022] As Figure 2 、 3 shown, the power shaft 2 is cylindrical. The supporting rollers 7 have two wheels that can slide on the rotating shaft and adjust the distance and position. The two wheels are driven to rotate by the power shaft 2 through gear transmission. The material of the wheels is polyurethane or hard rubber. It is required that the edges of the two wheels respectively press against the edges of the filling material 15. When the folding composite material passes through the supporting rollers 7, according to the width of the filling material 15, the distance and position between the two wheels of the supporting rollers 7 are set. The purpose is to press the filling material 15 and the folding material 14 tightly. The main function is to determine the edge position during the folding process.

[0023] As Figure 4 、 5As shown, the folding unit 8 includes a folding platform 8-3. Universal rolling balls 8-4 are evenly embedded on the folding platform 8-3 to facilitate the feeding during the folding process and reduce friction. Folding shafts 8-5 are arranged on both sides of the folding platform 8-3. The angle between the folding shafts 8-5 on the same side and the horizontal plane gradually decreases from the initial 90° to 0°. The folding platform 8-3 and the folding shafts 8-5 on both sides respectively form a first-level folding unit 8-1 and a second-level folding unit 8-2 with different folding directions.

[0024] Viewed from the feeding direction, two groups of folding shafts 8-5 are arranged on the two side edges of the folding platform 8-3. The bending angles of each group of folding shafts 8-5 are different, and they are all gradually bent from 90° with the horizontal plane to nearly 0°, and the bending angles can be adjusted according to requirements.

[0025] As Figure 6 、 7 shown, in the folding unit 8, it is divided into a first-level folding unit 8-1 and a second-level folding unit 8-2. The folding directions of the first-level folding unit 8-1 and the second-level folding unit 8-2 for the material are different. The design of the two-level folding unit provides selectivity for the folding method of the material. It can be folded from one side or from both sides. Folding shafts 8-5 are designed on both sides of the folding platform 8-3. And in order to fold the folded material 14 and the filling material 15 in the planar state according to the designed width, the bending angle between each side of the folding shaft 8-5 and the horizontal plane gradually changes from 90° to nearly 0°. Such a design ensures that the folded material can complete the folding process step by step. In addition, universal rolling balls 8-4 are embedded on the folding platform 8-3 to play a role in supporting and reducing friction, ensuring the smooth passage of the material.

[0026] The folding of the material is completed by a planar composite material being pressed against the folding edge by the edges of the two wheels of the support roller 7 and passing through the gradually bent folding shafts 8-5 step by step. Therefore, the bending angle of each side of the folding shaft 8-5 needs to gradually become smaller. The folded material 14 is under the traction force of the four groups of composite rollers 9 behind and completes the operation process from planar to folded.

[0027] The folding unit 8 can achieve a single-fold structure and a double-fold structure.

[0028] Single-fold structure: In the folding unit 8, folding shafts 8-5 are respectively arranged on both sides of the folding platform 8-3, and the bending angles in each group of folding shafts 8-5 are different. When the composite material needs to be folded once, as Figure 8 shown, the folded material 14 passes through the composite first double-sided tape 13 and completely wraps the filling material 15 after being folded from one side. This folding structure is to complete the folding and compounding of the composite material by using only the first-level folding unit 8-1 or the second-level folding unit 8-2.

[0029] Secondary folding structure: Folding axes 8-5 are respectively arranged on both sides of the folding platform 8-3 in the folding unit 8, and the bending angles of each folding axis 8-5 in each group are different. When the composite material needs to be folded twice, as Figure 9 shown, the folding material 14 passes through the composite first double-sided tape 13, first passes through the primary folding unit 8-1, folds the folding material along one side of the filling material 15, and then passes through the secondary folding unit 8-2, folds the other side of the folding material along the other side of the filling material 15, and completely wraps the filling material 15 therein. This folding structure uses the primary folding unit 8-1 and the secondary folding unit 8-2 to complete the folding and compounding of the composite material from both sides.

[0030] The device main body 1 is provided with the first double-sided tape 13. After the first double-sided tape 13 passes through a set of composite rollers 3, the light release film 13-1 on the lower side of the first double-sided tape 13 is collected by the lower take-up shaft. After the first double-sided tape 13 passes through two sets of composite rollers 4, the heavy release film 13-2 on the upper side of the first double-sided tape 13 is collected by the upper take-up shaft.

[0031] The folding material 14 is placed on the device main body 1. After the folding material 14 passes through the feeding support roller 14-1 and two sets of composite rollers 4, it is compounded with the lower side of the first double-sided tape 13.

[0032] The filling material 15 is placed on the device main body 1. After the filling material 15 passes through three sets of composite rollers 5, the supporting feeding shaft 6 and the supporting roller 7, it is compounded with the folding material 14 compounded with the first double-sided tape 13. The base paper of the filling material 15 is collected by the first base paper take-up roll 15-1.

[0033] The adhesive 16 is placed on the device main body 1. After the adhesive 16 passes through the peeling support shaft 16-2 and four sets of composite rollers 9, it is compounded with the folding material 14 compounded with the first double-sided tape 13 and the filling material 15. The base paper of the adhesive 16 is collected by the second base paper take-up roll 16-1.

[0034] The second double-sided tape 17 is placed on the device main body 1. After the second double-sided tape 17 passes through the double-sided tape peeling support shaft 17-2 and four sets of composite rollers 9, it is compounded with the folding material 14 compounded with the first double-sided tape 13, the filling material 15 and the adhesive 16. The base paper of the second double-sided tape 17 is collected by the release paper take-up roll 17-1.

[0035] The die-cutting knife on the die-cutting knife shaft 10 performs die-cutting on the folding material 14 compounded with the first double-sided tape 13, the filling material 15, the adhesive 16 and the second double-sided tape 17. After the die-cutting waste passes through the waste discharge support shaft 11-2, it is collected by the waste discharge take-up shaft 11-1.

[0036] The equipment main body 1 is provided with a number of power shafts 2. The power shafts 2 drive a corresponding set of composite rollers 3, a second set of composite rollers 4, a third set of composite rollers 5, support rollers 7, a fourth set of composite rollers 9 and a die cutting tool shaft 10 through meshing gears.

[0037] A continuous folding and composite production method for coils, comprising the following steps: S1. Composite the double-sided tape with the folding material On the equipment main body 1, there is a feeding shaft for placing the first double-sided tape 13. After the first double-sided tape 13 passes through a set of composite rollers 3, the adhesive film is peeled off, and the light release film 13-1 on the lower side is collected by the lower take-up shaft. After the folding material 14 is unrolled, it bypasses the material guiding support roller 14-1, passes through the second set of composite rollers 4 from below and is composite with the lower side of the first double-sided tape 13. At the same time, after passing through the second set of composite rollers 4, the heavy release film 13-2 on the upper side of the first double-sided tape 13 is peeled off. Here, it is required that the width of the first double-sided tape 13 is the same as that of the folding material 14.

[0038] S2. Composite the filling material with the folding material After the folding material 14 composite with the first double-sided tape 13 in S1 peels off the heavy release film 13-2 on the upper surface, it is composite with the filling material 15. The filling material 15 is fed from the upper feeding shaft and is composite through the third set of composite rollers 5. Usually, the width of the filling material 15 is smaller than that of the folding material 14, and the composite position of the filling material 15 on the surface of the folding material 14 can be adjusted as required.

[0039] S3. Fold the composite material The composite material completed in S2 passes through the support material guiding shaft 6 and the support rollers 7 and then enters the folding unit 8.

[0040] S4. Composite the surface layer material The self-adhesive 16 on the equipment main body 1 releases the surface layer self-adhesive surface layer material, passes through the peeling support shaft 16-2 to peel off the silicone paper and enters the fourth set of composite rollers 9. The silicone paper peeled off from the surface layer is wound up by the second base paper take-up roll 16-1. The second double-sided tape 17 at the lower part of the equipment main body 1 releases the double-sided tape, passes through the double-sided tape peeling support shaft 17-2 and then peels off the light release force silicone oil base paper, and this silicone oil base paper is wound up by the release paper take-up roll 17-1. As Figure 10 、 11 shown, the surface layer with the self-adhesive 16 and the second double-sided tape 17 respectively pass through the fourth set of composite rollers 9 from above and below and are composite with the folded material.

[0041] S5. Die cutting The folded material 14 that has completed the surface layer lamination passes through the die-cutting knife shaft 10. With the heavy release force silicone paper base of the bottom second double-sided tape 17 as the reference, the overall composite material is die-cut by the die-cutting knives on the die-cutting knife shaft 10. After the die-cut waste passes through the waste discharge support shaft 11-2, the waste discharge take-up shaft 11-1 completes the material collection. After the die-cut material passes through the finished product take-up support shaft 11, the finished product take-up shaft 12 completes the winding.

After passing through the second set of lamination rollers 4, the heavy release film 13-2 is peeled off. The filling material 15 is released and laminated with the first double-sided tape 13 from above through the third set of lamination rollers 5, and the filling material 15 is positioned and laminated on the upper surface of the folded material 14. Along the material guiding direction, it is required that the edge of the filling material 15 is aligned with the left side of the folded material 14 for lamination. The filling material 15 is released from the unwinding reel, passes through the third set of lamination rollers 5, and then the two sides of the filling material 15 are pressed by the wheels on both sides of the support roller 7. After peeling off the silicone release paper, the lamination of the two layers of materials is completed. The laminated material is as Figure 13 shown. The filling material 15 is laminated on one side of the folded material 14.

[0045] 4. Folding: In this example, a single-fold method is adopted. That is, from the perspective of the material guiding direction, the material on the left side is folded and laminated to the right side to obtain the appearance as Figure 14 shown.
