Description

Technical Field

[0001] The invention relates to the technical field of adhesive back cutting, and in particular to a manufacturing system of a circular and flat combined functional adhesive device. Background Art

[0002] In order to adapt to the gluing scenarios of different shapes, the adhesive backing needs to be cut into different shapes by die-cutting equipment. Before entering the die-cutting equipment, the raw material to be cut is generally a multi-layer structure, that is, it includes an upper release film, an intermediate adhesive strip and a lower release film. After the raw material is fed into the die-cutting equipment, the die-cutting equipment cuts the upper release film and the intermediate adhesive strip into the required shape through a die-cutting tool, and then collects the excess waste to obtain the adhesive backing of the corresponding shape. Generally speaking, in the cutting and molding manufacturing process of an adhesive backing, only one type of die-cutting tool can be used, such as a die-cutting tool that can only use a circular knife, or a die-cutting tool that can only use a flat knife. However, the circular knife and the flat knife die-cutting tool are applicable to different scenarios. The circular knife has a fast cutting speed and high precision, but wears quickly and has a high maintenance cost. The flat knife has a low maintenance cost and the cutting depth is easy to control, but the incision is not as smooth as the circular knife and the cutting speed is slow. Different types of die-cutting tools may be applicable at different stages of the manufacturing process of adhesive backing. However, it is currently impossible to select the appropriate type of die-cutting tool according to the characteristics of the process, resulting in low overall manufacturing efficiency and high cost.

[0013] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0014] The present invention provides a circular and flat combined functional adhesive device manufacturing system, which is used to cut materials to be cut into functional adhesive devices with required shapes. The system mainly includes circular cutting equipment and flat cutting equipment. The circular cutting equipment uses a circular knife to cut the materials, while the flat cutting equipment uses a flat knife to cut the materials sent out after being cut by the circular cutting equipment. The two cooperate with each other, combining the respective advantages of the circular cutting equipment and the flat cutting equipment, thereby improving the manufacturing efficiency of the functional adhesive device.

[0015] Among them, the difficulty of the circular cutting equipment and the flat cutting equipment cooperating with each other for cutting is that the circular cutting equipment and the flat cutting equipment have different ways of conveying materials; the circular cutting equipment continuously and uninterruptedly conveys materials through a circular cutting conveying mechanism, and cuts the materials through a circular cutting die while the materials are moving; while the flat cutting equipment intermittently conveys materials through a flat cutting conveying mechanism, and cuts the materials through a flat cutting die when the materials stop moving, and then the materials continue to move, and the flat cutting die cuts the materials at the next position; due to the asynchronous conveying speed, it will be difficult to locate the cutting position after the materials cut by the circular cutting equipment are sent into the flat cutting equipment; for this reason, in the present technical scheme, a positioning die is set in the circular cutting die, and positioning knife patterns are set on the positioning die, and through positioning The knife pattern can form positioning holes at positions on the material that are not covered with adhesive backing material while the positioning die is cutting the material; at the same time, positioning posts and clearance grooves are provided on the flat-cutting die, and the positioning posts can be inserted into the positioning holes on the material and tension the material, thereby accurately defining the position of the material relative to the cutting piece. At this time, the clearance groove plays a role in avoiding the positioning posts, so that the positioning posts can pass through the positioning holes without affecting the material resting on the support plate; wherein, after the positioning posts are inserted into the positioning holes on the material, they will exert a guiding force on the flexible material itself, forcing the material to adjust its own position, and keeping the current cutting part of the cutting piece tensioned, avoiding position deviation of the cutting piece during cutting, thereby solving the problem of coordinated cutting between circular cutting equipment and flat cutting equipment, and effectively improving the manufacturing efficiency of functional adhesive devices.

[0016] A plurality of groups of positioning knife marks can be arranged on the positioning knife die. In one rolling cycle of the positioning knife die, a plurality of groups of positioning holes can be formed by cutting the material, thereby improving the cutting efficiency of the positioning holes. At the same time, each group of positioning knife marks includes two symmetrically arranged positioning cutters, which can form two symmetrically arranged positioning holes on the material. The positions of the positioning holes on the material are different according to the positions of the positioning cutters. Preferably, the positioning cutters are symmetrically arranged perpendicular to the conveying direction of the material, so that the flat cutting knife die can complete the cutting of the material perpendicular to the conveying direction of the material. Corresponding to the two positioning holes, two positioning columns are arranged on the cutting piece, and the part of the material to be cut can be tensioned in a direction perpendicular to the conveying direction of the material through the two positioning columns, so as to facilitate the flat cutting knife die to perform cutting.

[0017] The positioning cutter can cut to form a circular positioning hole, and the positioning column is a cylindrical shape with a suitable size; compared with other shapes, the circular positioning hole and the cylindrical positioning column have better adaptability, and the difficulty of the positioning column entering from different positions of the edge of the circular positioning hole is consistent, which can improve the accuracy of the positioning column insertion. Among them, the bottom of the positioning column can be set to a cone with a smooth head. The cone reduces the size of the bottom end of the positioning column. Even if there is a deviation between the positioning hole and the positioning column, the bottom end of the positioning column can enter the knife positioning hole, so that the positioning column can tighten the material of this part; at the same time, setting the bottom end of the positioning column to a smooth head can also prevent the positioning column from piercing the material.

[0018] A tensioning device and a roller feeding device are arranged in the flat cutting conveying mechanism of the flat cutting equipment. The pressure plate and guide roller of the tensioning device will cooperate to clamp the material. At the same time, the active roller and the driven roller of the roller feeding device can also cooperate to clamp the material. Through the active operation of the active roller, the material can be kept tensioned and pressed against the support plate during the conveying process, which is convenient for cutting the cutting piece.

[0019] In addition, the manufacturing system also includes a material receiving device, which can use a material receiving cutting die to cut and remove the part of the material where the positioning hole is set, and then use a winding device to wind up the waste material and the finished product to obtain the required functional adhesive device.

[0035] Example

[0036] An embodiment of the present invention provides a system for manufacturing a circular and flat combined functional adhesive device. The functional adhesive device is generally an adhesive strip used for bonding display screens. It can be formed by stacking materials such as a release film 24, a backing adhesive, and a protective film 26. During the manufacturing process, the original material 5 needs to be stacked and then the stacked material 5 needs to be cut to obtain a functional adhesive device with a desired shape.

[0037] Reference Figure 1 The circular and flat combined functional adhesive device manufacturing system provided in this embodiment mainly includes a circular cutting device 1, a flat cutting device 11 and a material receiving device 29. Those skilled in the art understand that circular knives and flat knives are two common types of cutting tools in die-cutting processing. The circular knife is generally installed on a rotary die-cutting machine, and cutting is achieved by the rotation of the knife. The working mode of circular knife die-cutting is similar to the rotation of a drum. The cutting is completed by the contact and pressure between the circular knife and the material, and the circular knife die-cutting can achieve uninterrupted cutting through continuous rotation, which is suitable for large-scale rapid production. The flat knife is also called flat die-cutting, which uses a knife that moves in parallel up and down for cutting. It is generally installed on a flat die-cutting machine and completes the cutting by applying vertical pressure to the material.

[0038] Circular knife die cutting and flat knife die cutting have their own advantages and disadvantages. For example, circular knife die cutting has high speed and high precision, but it wears quickly and has high maintenance costs. Flat knife has low maintenance costs and easy to control cutting depth, but the incision is not as smooth as that of circular knife and the cutting speed is slow. Combining circular knife die cutting and flat knife die cutting can effectively improve the material cutting efficiency, thereby improving the production efficiency of products. However, the difficulty of the circular cutting device 1 and the flat cutting device 11 cooperating with each other for cutting is that the circular cutting device 1 and the flat cutting device 11 have different ways of conveying the material 5; the circular cutting device 1 continuously and uninterruptedly conveys the material 5 through the circular cutting conveying mechanism 3, and while the material 5 is moving, the circular cutting die 4 cuts the material 5; while the flat cutting device 11 intermittently conveys the material 5 through the flat cutting conveying mechanism, and when the material 5 stops moving, the flat cutting die 14 cuts the material 5, and then the material 5 continues to move, and the flat cutting die 14 cuts the next position of the material 5; due to the asynchronous conveying speed, it will be difficult to locate the cutting position after the material 5 cut by the circular cutting device 1 is sent into the flat cutting device 11.

[0039] To this end, in the manufacturing system provided in this embodiment, the circular cutting device 1, the flat cutting device 11 and the material receiving device 29 are improved to solve the problems existing in the prior art.

The material receiving equipment 29 includes a material receiving frame 30, a material receiving conveying mechanism 31, a material receiving cutting die 32 and a winding device 33; the material receiving conveying mechanism 31 is installed on the material receiving frame 30, and is suitable for conveying material 5 along a preset direction; the material receiving cutting die 32 is installed on the material receiving frame 30, and is used to cut off the part including the positioning hole 10 on the material 5 sent out by the flat cutting device 11; the winding device 33 includes a waste winding roller 34 and a finished product winding roller 35, the waste winding roller 34 is used to wind up the waste cut by the material receiving cutting die 32, and the finished product winding roller 35 is used to wind up the functional adhesive device obtained after cutting by the material receiving cutting die 32.

[0041] First, the circular cutting device 1 is introduced. Figure 2 The circular cutting frame 2 of the circular cutting equipment 1 is provided with a plurality of rolling conveying devices, a plurality of rolling shafts 25 and a plurality of circular cutting dies 4.

[0042] Among them, the rolling conveying device forms the circular cutting conveying mechanism 3 of the circular cutting device 1, and the rolling conveying device generally includes two circular rollers symmetrical up and down, and the material 5 can pass through between the two circular rollers and be clamped by the circular rollers, and then the circular rollers can rotate relative to the circular cutting frame 2 under the action of the driving motor, and drive the material 5 to move along the preset conveying direction. In the circular cutting device 1 provided in this embodiment, in the conveying direction of the material 5, a rolling conveying device can be respectively arranged at the upstream, midstream and downstream positions, and then cooperated with other guide circular rollers to realize the conveying of the material 5 in the circular cutting device 1.

[0043] The reel 25 is mounted on the circular cutting machine frame 2 and includes a rotatable sleeve. The material 5 to be used is wound on the sleeve and can be continuously unwound when the material 5 is conveyed.

[0044] The circular cutting die 4 also includes two circular rollers symmetrically arranged in an upper and lower direction, but the difference is that the outer surface of the circular roller located at the upper side is provided with knife patterns, and these knife patterns can cut the material 5 into a desired shape when in contact with the material 5. For a circular cutting device 1, multiple circular cutting die dies 4 can be provided to cut the desired complex shape on the material 5 by multiple cutting.

[0045] In this embodiment, one of the circular cutting dies 4 is set as the positioning cutting die 8. Figure 5 , which shows the structure of the positioning knife die 8. Among them, a plurality of groups of positioning knife marks 9 are provided on the positioning knife die 8, and each group of positioning knife marks 9 includes two symmetrically arranged positioning cutters 19, and the positioning cutters 19 are used to cut the positioning holes 10 on the material 5. Specifically, the two positioning cutters 19 in each group of positioning knife marks 9 are symmetrically arranged perpendicular to the conveying direction of the material 5, and each positioning cutter 19 is suitable for cutting the material 5 to form one of the positioning holes 10. Specifically, two positioning cutters 19 are provided in each group of positioning knife marks 9, and are arranged along the length direction of the positioning knife die 8. The two are symmetrically arranged relative to the conveying direction, so that corresponding positioning holes 10 can be formed on the side position of the material 5 perpendicular to the conveying direction. Among them, the positioning cutters 19 are suitable for cutting the material 5 to form a circular positioning hole 10.

[0046] The structure of the positioning hole 10 can refer to Figure 7 ,exist Figure 7 In the figure, the middle part is the adhesive material 23, and the release films 24 are located below and above the adhesive material 23. At the same position on the two release films 24, a circular positioning hole 10 as shown in the figure is formed by cutting with a positioning cutter 19.

[0047] Next, the flat cutting device 11 is introduced. Figure 3 A flat cutting conveying mechanism and a flat cutting die 14 are arranged on the flat cutting frame 12 of the flat cutting device 11, wherein the flat cutting conveying mechanism includes a tensioning device 37 and a roller feeding device 20 located at the upstream and downstream positions of the flat cutting die 14 along the conveying direction of the material 5, the tensioning device 37 includes a pressure plate 38 and a guide roller, the roller feeding device 20 includes a symmetrically arranged active roller 21 and a driven roller 22, the pressure plate 38, the guide roller and the active roller 21, the driven roller 22 are all suitable for cooperating with each other to clamp the material 5 and make the material 5 tighten against the support plate 16.

[0048] Specifically, the tensioning device 37 is arranged at the upstream position of the flat cutting frame 12 in the conveying direction of the material 5, and receives the material 5 sent from the circular cutting device 1, and clamps the material 5 through the pressure plate 38 and the guide roller. The pressure plate 38 can be arranged to be connected with the flat cutting frame 12 through a torsion spring, so that the pressure plate 38 keeps pressing the material 5. The roller conveying device 20 is arranged at the downstream position of the flat cutting frame 12 in the conveying direction of the material 5, and includes a driving roller 21 and a driven roller 22 arranged symmetrically up and down. The driving roller 21 is driven by a driving motor to realize autonomous rotation, and the driven roller 22 rotates accordingly due to the friction generated when the material 5 is driven by the driving roller 21. The material 5 is clamped between the driving roller 21 and the driven roller 22, and cooperates with the tensioning device 37 to make the material 5 tightly pressed against the support plate 16 of the flat cutting die 14.

[0049] The flat cutting die 14 includes multiple groups of cylinders, which can drive the cutting piece 15 to move up and down. A support plate 16 is arranged below the cutting piece 15. The support plate 16 is used to provide a base for the material 5. The support plate 16 cooperates with the cutting piece 15 to apply pressure to the material 5, thereby completing the flat die cutting of the material 5. Figure 6 Two downwardly extending positioning posts 17 are provided at both ends of the cutting piece 15 in the length direction, and two clearance grooves 18 are provided on the support plate 16 located below the cutting piece 15 corresponding to the two positioning posts 17. The clearance grooves 18 can avoid the positioning posts 17 when the cutting piece 15 moves downward, so that the knife marks on the cutting piece 15 can contact the material 5 and exert pressure on the material 5.

[0050] In addition, the positioning post 17 is cylindrical in shape and has a size that matches the positioning hole 10 cut out on the material 5. Compared with other shapes, the circular positioning hole 10 and the cylindrical positioning post 17 have better adaptability, and the difficulty of the positioning post 17 entering from different positions of the edge of the circular positioning hole 10 is consistent, which can improve the accuracy of the insertion of the positioning post 17. Furthermore, the bottom of the positioning post 17 can be set to a cone with a smooth head, and the cone reduces the size of the bottom end of the positioning post 17. Even if there is a position deviation between the positioning hole 10 and the positioning post 17, the bottom end of the positioning post 17 can enter the knife positioning hole 10, so that the positioning post 17 can tighten the material 5 in this part; at the same time, setting the bottom end of the positioning post 17 to a smooth head can also prevent the positioning post 17 from piercing the material 5.

[0051] Finally, the winding equipment is introduced. Figure 4The winding frame of the winding device is provided with a material receiving and conveying mechanism 31, a material receiving and cutting die 32 and a winding device 33, wherein the material receiving and conveying mechanism 31 can adopt the same rolling conveying device as the circular cutting device 1, and the material receiving and cutting die 32 adopts a circular die cutting structure, which also includes two circular rollers symmetrically arranged above and below, and a knife pattern is arranged on the circular roller located above, and the knife pattern can cut the material 5; in addition, the winding device 33 includes a waste material winding roller 34 and a finished product winding roller 35, which respectively wind up the cut waste material and the finished product. Among them, the waste material winding roller 34 and the finished product winding roller 35 are driven by a motor, and can cooperate with the material receiving and conveying mechanism 31 to pull the material 5 to move and autonomously take away the waste material.

[0052] Specifically, refer to Figure 7 , the final functional adhesive device only needs to be the portion of the material 5 sent out by the flat cutting device 11 corresponding to the portion with the adhesive backing material 23, so the portion of the material 5 including the positioning hole 10 needs to be cut off. The positioning hole 10 is required for positioning during the cutting process of the flat cutting device 11, so a material receiving and cutting die 32 is set on the material receiving device 29 to cut and remove the portion of the material 5 including the positioning hole 10. After the material 5 passes through the material receiving and cutting die 32, it is divided into two parts, one of which is the outer frame waste 36, which is taken away by the waste winding roller 34, and the remaining part is the required product, which can be wound and stored by the finished product winding roller 35.

[0053] In the overall manufacturing process, the material 5 passes through the circular cutting device 1, the flat cutting device 11 and the material receiving device 29 in sequence, and finally obtains a functional adhesive device with a desired shape. Among them, the operation process of the circular cutting device 1 is roughly as follows: the release film 24 is placed on the rolling shaft 25 located at the upstream end. After the release film 24 is introduced into the circular cutting conveying mechanism 3, the protective film 26 is firstly pasted on the bottom surface of the release film 24, and then the adhesive material 23 is pasted on the top surface of the release film 24. After that, after being cut by the positioning die 8, the adhesive waste 27 and positioning waste 28 removed by cutting are taken away by the corresponding rolling shaft 25. The adhesive waste 27 here is the unnecessary adhesive material 23 on the material 5, and the positioning waste 28 is the excess release film 24 waste after the positioning hole 10 is cut on the material 5. Then, one side of the release film 24 is pasted on the top surface of the cut material 5, and the obtained product is finally sent out from the circular cutting device 1. The product sent out from the circular cutting device 1 will be sent to the flat cutting device 11. The flat cutting conveying mechanism in the flat cutting device 11 drives the material 5 to be intermittently conveyed downstream, and when it stops, it controls the flat cutting die 14 to cut the material 5. In this process, the positioning column 17 on the cutting piece 15 in the flat cutting die 14 will be inserted into the positioning hole 10 on the material 5 and tighten the part of the material 5, so that the cutting piece 15 can accurately position the material 5 and complete the flat knife die cutting of the material 5; after the flat knife die cutting is completed, the obtained product will be sent out from the flat cutting device 11. The material 5 sent out from the flat cutting device 11 is cut by the material receiving device 29 to obtain the required functional adhesive device.

[0054] The present invention provides a circular and flat combined functional adhesive device manufacturing system, which is used to cut a material 5 to be cut into a functional adhesive device with a desired shape. The system mainly comprises a circular cutting device 1 and a flat cutting device 11. The circular cutting device 1 uses a circular knife to cut the material 5, and the flat cutting device 11 uses a flat knife to cut the material 5 sent out after being cut by the circular cutting device 1. The cooperation of the two, combined with the respective advantages of the circular cutting device 1 and the flat cutting device 11, improves the manufacturing efficiency of the functional adhesive device.

[0055] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
