Description

Technical Field

[0001] The utility model relates to the technical field of adhesive cutting, in particular to a manufacturing system for a functional adhesive device combining a round cutter and a flat cutter. Background Art

[0002] To adapt to different-shaped gluing scenarios, the adhesive needs to be cut into different shapes through a die-cutting device. Before entering the die-cutting device, 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 device, the die-cutting device cuts the upper release film and the intermediate adhesive strip into the required shapes through die-cutting tools, and then collects the excess waste materials to obtain the adhesive of the corresponding shape. Generally speaking, in the manufacturing process of cutting and forming an adhesive, only one type of die-cutting tool can be used. For example, only a round die-cutting tool can be used, or only a flat die-cutting tool can be used. However, the die-cutting tools of round knives and flat knives are suitable for different scenarios. The round knife has a fast cutting speed and high precision, but it wears quickly and has a high maintenance cost. The flat knife has a low maintenance cost and is easy to control the cutting depth, but the cut is not as smooth as that of the round knife and the cutting speed is slow. In different process stages during the manufacturing process of the adhesive, the types of die-cutting tools that may be applicable are different, but currently, it is 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 costs. Summary of the Utility Model

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

[0014] The present invention provides a manufacturing system for a functional adhesive device with a combination of circular and flat cutting. This manufacturing system is used to cut the material to be cut into a functional adhesive device with the required shape. It mainly includes a circular cutting device and a flat cutting device. The circular cutting device uses a circular knife to cut the material, and the flat cutting device uses a flat knife to cut the material sent out after being cut by the circular cutting device. The two cooperate, combining the respective advantages of the circular cutting device and the flat cutting device, and improving the manufacturing and production efficiency of the functional adhesive device.

[0015] Among them, the difficulty in the coordinated cutting of the circular cutting device and the flat cutting device lies in that their material conveying methods are different; the circular cutting device continuously conveys the material through the circular cutting conveying mechanism, and while the material is moving, cuts the material with the circular cutting die; while the flat cutting device intermittently conveys the material through the flat cutting conveying mechanism, and when the material stops moving, cuts the material with the flat cutting die, and then the material continues to move, and the flat cutting die cuts the next position of the material; due to the asynchronous conveying speeds, it is difficult to position the cutting position after the material cut by the circular cutting device is sent into the flat cutting device; for this reason, in this technical solution, a positioning die is set in the circular cutting die, and positioning knife lines are set on the positioning die, and through the positioning knife lines, positioning holes can be cut and formed at the positions on the material where there is no adhesive material covered while the positioning die cuts the material; at the same time, positioning posts and relief grooves are set on the flat cutting die, 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, and at this time the relief groove plays a role in avoiding the positioning posts, so that the positioning posts can pass through the positioning holes without affecting the material from adhering to the support plate; among them, after the positioning posts are inserted into the positioning holes on the material, a guiding force is applied to the flexible material itself, forcing the material to adjust its own position and keeping the currently cut part of the cutting piece tensioned, avoiding deviation in the position of the cutting piece during cutting, thus solving the problem of the coordinated cutting of the circular cutting device and the flat cutting device and effectively improving the manufacturing production efficiency of the functional adhesive device.

[0016] Multiple groups of positioning knife lines can be set on the positioning die. In one rolling cycle of the positioning die, multiple groups of positioning holes can be cut and formed on the material to improve the cutting efficiency of the positioning holes; at the same time, each group of positioning knife lines includes two symmetrically arranged positioning cutters, and these two positioning cutters can form two symmetrically arranged positioning holes on the material; according to the different positions of the positioning cutters, the positions of the positioning holes on the material are also different. Preferably, the positioning cutters are symmetrically arranged perpendicular to the conveying direction of the material, so as to facilitate the flat cutting die to complete the cutting of the material in the direction perpendicular to the conveying direction of the material; corresponding to the two positioning holes, two positioning posts are set on the cutting piece, and through the two positioning posts, the currently to-be-cut part of the material can be tensioned in the direction perpendicular to the conveying direction of the material, so as to facilitate the flat cutting die to perform cutting.

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

[0018] In the flat cutting conveying mechanism of the flat cutting equipment, a tensioning device and a roller feeding device are arranged. The pressing plate and the guiding roller of the tensioning device will cooperate to clamp the material. At the same time, the driving roller and the driven roller of the roller feeding device can also cooperate to clamp the material. Through the active operation of the driving roller, the material can be kept tensioned and close to the supporting plate during the conveying process, which is convenient for the cutting piece to perform cutting.

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

[0035] Embodiment

[0036] The embodiment of the present utility model provides a manufacturing system for a circular-flat combined functional adhesive device. The functional adhesive device is generally an adhesive strip for bonding a display screen, which can be formed by laminating material layers such as a release film 24, an adhesive, and a protective film 26. During the manufacturing process, the original material 5 needs to be laid, and then the laid material 5 is cut to obtain a functional adhesive device with a desired shape.

[0037] Refer to Figure 1 , the manufacturing system for a circular-flat combined functional adhesive device 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 knives in die cutting. Among them, circular knives are generally installed on a rotary die cutting machine and achieve cutting through the rotation of the knives. The working mode of circular knife die cutting is similar to the rotation of a drum, and cutting is completed through the contact and pressure between the circular knife and the material. Moreover, circular knife die cutting can achieve continuous cutting through continuous rotation, which is suitable for large-scale and rapid production. Flat knives, also known as flatbed die cutting, use knives that move up and down in parallel for cutting, and are generally installed on a flatbed die cutting machine, and cutting is completed by applying pressure in the vertical direction to the material.

[0038] Round die cutting and flat die cutting have their respective advantages and disadvantages. For example, round die cutting is fast and accurate, but has fast wear and high maintenance costs. Flat die cutting has low maintenance costs and easy control of cutting depth, but the cut is not as smooth as that of round die cutting and the cutting speed is slow. Combining round die cutting and flat die cutting can effectively improve the cutting efficiency of the material 5, and thus improve the production and manufacturing efficiency of the product. However, the difficulty in the combined cutting of the round cutting device 1 and the flat cutting device 11 lies in that the conveying methods of the round cutting device 1 and the flat cutting device 11 for the material 5 are different; the round cutting device 1 continuously conveys the material 5 through the round cutting conveying mechanism 3, and while the material 5 is moving, the round 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 is difficult to position the cutting position after the material 5 cut by the round cutting device 1 is sent into the flat cutting device 11.

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

[0040] Refer to Figure 1 and Figure 2, a circular cutting device 1, which includes a circular cutting machine frame 2, a circular cutting conveying mechanism 3 and a plurality of circular cutting dies 4; the circular cutting conveying mechanism 3 is installed on the circular cutting machine frame 2 and is adapted to continuously convey the material 5 along a preset direction; the circular cutting die 4 includes a support roller 6 and a circular cutting roller 7 rotatably installed on the circular cutting machine frame 2, and is adapted to cut the material 5 located between the support roller 6 and the circular cutting roller 7 through the circular cutting roller 7; among all the circular cutting dies 4, a positioning die 8 is set, and a positioning knife pattern 9 is provided on the positioning die 8, and the positioning knife pattern 9 is adapted to cut a positioning hole 10 on the material 5; a flat cutting device 11, which includes a flat cutting machine frame 12, a flat cutting conveying mechanism and a flat cutting die 14; the flat cutting conveying mechanism is installed on the flat cutting machine frame 12 and is adapted to continuously convey the material 5 sent out by the circular cutting device 1 along a preset direction; the flat cutting die 14 includes a cutting member 15 and a support plate 16 installed on the flat cutting machine frame 12, and the cutting member 15 is configured to be adapted to reciprocate up and down relative to the support plate 16 to cut the material 5 located between the support plate 16 and the cutting member 15; the cutting member 15 is provided with a positioning post 17 corresponding to the positioning hole 10 on the material 5, and the support plate 16 is provided with a relief groove 18 at a position corresponding to the positioning post 17, and the positioning post 17 is adapted to insert into the positioning hole 10 on the material 5 to tension the material 5 before the cutting member 15 cuts the material 5. A material receiving device 29, which includes a material receiving machine 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 machine frame 30 and is adapted to convey the material 5 along a preset direction; the material receiving cutting die 32 is installed on the material receiving machine frame 30 and is used to cut off a part of the material 5 sent out by the flat cutting device 11 including the positioning hole 10; 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 the waste cut off by the material receiving cutting die 32, and the finished product winding roller 35 is used to wind the functional adhesive device obtained after being cut by the material receiving cutting die 32.

[0041] First, the circular cutting device 1 is introduced. Refer to Figure 2 , a plurality of rolling conveying devices, a plurality of rolling shafts 25 and a plurality of circular cutting dies 4 are arranged on the circular cutting machine frame 2 of the circular cutting device 1.

[0042] Among them, the rolling conveying device forms the circular cutting conveying mechanism 3 of the circular cutting device 1. The rolling conveying device generally includes two upper and lower symmetric circular rollers. The material 5 can pass through between the two circular rollers and be clamped by the circular rollers. Then, the circular rollers can rotate relative to the circular cutting machine frame 2 under the action of a driving motor and drive the material 5 to move along a 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, middle and downstream positions, and then cooperate with other guiding circular rollers to realize the conveying of the material 5 in the circular cutting device 1.

[0043] The winding roller 25 is installed on the circular cutting frame 2 and includes a rotatable bushing. The material 5 to be used is wound on the bushing and can continuously unwind during the conveyance of the material 5.

[0044] The circular cutting die 4 also includes two circular rollers that are symmetrically arranged up and down. The difference is that the outer surface of the upper circular roller is provided with cutting lines. These cutting lines can cut and form the required shape on the material 5 when contacting the material 5. For a circular cutting device 1, multiple circular cutting dies 4 can be provided to cut out the required complex shape on the material 5 through multiple cutting operations.

[0045] In this embodiment, one of the circular cutting dies 4 is set as the positioning die 8. Refer to Figure 5 , which shows the structure of the positioning die 8. Among them, the positioning die 8 is provided with multiple groups of positioning cutting lines 9. Each group of positioning cutting lines 9 includes two symmetrically arranged positioning cutters 19. The positioning cutters 19 are used to cut and form the positioning holes 10 on the material 5. Specifically, the two positioning cutters 19 in each group of positioning cutting lines 9 are symmetrically arranged perpendicular to the conveyance direction of the material 5, and each positioning cutter 19 is adapted to cut the material 5 to form one of the positioning holes 10. Specifically, two positioning cutters 19 are provided in each group of positioning cutting lines 9 and are arranged along the length direction of the positioning die 8. The two are symmetrically arranged with respect to the conveyance direction, so as to form corresponding positioning holes 10 at the side position perpendicular to the conveyance direction on the material 5. Among them, the positioning cutter 19 is adapted to cut the material 5 to form circular positioning holes 10.

[0046] The structure of the positioning hole 10 can be referred to Figure 7 , in Figure 7 , 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, circular positioning holes 10 as shown in the figure are cut and formed by the positioning cutters 19.

[0047] Next, the flat cutting device 11 will be introduced. Refer to Figure 3 , on the flat cutting frame 12 of the flat cutting device 11, a flat cutting conveyance mechanism and a flat cutting die 14 are provided. Among them, the flat cutting conveyance mechanism includes a tensioning device 37 and a roller feeding device 20 located upstream and downstream of the flat cutting die 14 along the conveyance direction of the material 5. The tensioning device 37 includes a pressing plate 38 and a guiding roller. The roller feeding device 20 includes a driving roller 21 and a driven roller 22 that are symmetrically arranged. The pressing plate 38, the guiding roller, and the driving roller 21 and the driven roller 22 are all adapted to cooperate with each other to clamp the material 5 and make the material 5 tightly adhere to 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. It receives the material 5 sent out from the circular cutting device 1 and clamps the material 5 through the pressing plate 38 and the guide roller. The pressing plate 38 can be arranged to be connected to the flat cutting frame 12 through a torsion spring so that the pressing plate 38 keeps pressing against the material 5. The roller feeding device 20 is arranged at the downstream position of the flat cutting frame 12 in the conveying direction of the material 5. It includes a driving roller 21 and a driven roller 22 which are symmetrically arranged up and down. The driving roller 21 is driven by a driving motor to rotate independently, and the driven roller 22 rotates following 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 abut against the support plate 16 of the flat cutting die 14.

[0049] The flat cutting die 14 includes multiple groups of cylinders, and these cylinders can drive the cutting member 15 to reciprocate up and down. A support plate 16 is arranged below the cutting member 15. The support plate 16 is used to provide a base for the material 5. It cooperates with the cutting member 15 to apply pressure to the material 5 together, thereby completing the flat die cutting of the material 5. Refer to Figure 6 , at both ends of the cutting member 15 in the length direction, two positioning columns 17 extending downward are provided. On the support plate 16 located below the cutting member 15, two relief grooves 18 corresponding to the two positioning columns 17 are provided. The relief grooves 18 can avoid the positioning columns 17 when the cutting member 15 moves downward, so that the knife pattern on the cutting member 15 can contact the material 5 and apply pressure to the material 5.

[0050] In addition, the positioning column 17 is cylindrical with a size adapted to the positioning hole 10 cut out on the material 5. Compared with other shapes, the circular positioning hole 10 and the cylindrical positioning column 17 have better adaptability. The difficulty for the positioning column 17 to enter from different positions on the edge of the circular positioning hole 10 is the same, which can improve the accuracy of inserting the positioning column 17. Further, the bottom of the positioning column 17 can be set as a conical shape with a smooth head. The conical shape reduces the size of the bottom end of the positioning column 17. Even if there is a deviation in the position between the positioning hole 10 and the positioning column 17, the bottom end of the positioning column 17 can still enter the knife positioning hole 10, so that the positioning column 17 can tension the material 5 in this part; at the same time, setting the bottom end of the positioning column 17 as a smooth head can also prevent the positioning column 17 from piercing through the material 5.

[0051] Finally, the winding device is introduced. Refer to Figure 4, a material receiving and conveying mechanism 31, a material receiving cutting die 32, and a winding device 33 are provided on the winding frame of the winding device. The material receiving and conveying mechanism 31 can adopt the same rolling conveying device as the circular cutting device 1. The material receiving cutting die 32 adopts a circular die cutting structure, which also includes two circular rollers that are symmetrically arranged up and down, and a knife pattern is provided on the upper circular roller, and the knife pattern can cut the material 5. In addition, the winding device 33 includes a waste winding roller 34 and a finished product winding roller 35, which wind the cut waste and finished products respectively. Among them, both the waste winding roller 34 and the finished product winding roller 35 are driven by motors to operate, and can cooperate with the material receiving and conveying mechanism 31 to pull the material 5 to move and take away the waste automatically.

[0052] Specifically, referring to Figure 7 , the final functional adhesive device only needs the part corresponding to the part with the back adhesive material 23 from the material 5 sent out by the flat cutting device 11. Therefore, the part of the material 5 including the positioning holes 10 needs to be cut off. During the cutting process of the flat cutting device 11, positioning needs to be carried out through the positioning holes 10. Therefore, a material receiving cutting die 32 is provided on the material receiving device 29 to cut off the part of the material 5 including the positioning holes 10. After the material 5 passes through the material receiving cutting die 32, it is divided into two parts. One part is the outer frame waste 36, and this part of the outer frame waste 36 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] During the overall manufacturing process, the material 5 sequentially passes through the circular cutting device 1, the flat cutting device 11, and the material receiving device 29, and finally a functional adhesive device with the required shape is obtained. Among them, the operation process of the circular cutting device 1 is roughly as follows: The release film 24 is placed on the outermost upstream roller shaft 25. After introducing the release film 24 into the circular cutting conveying mechanism 3, first, a protective film 26 is attached to the bottom surface of the release film 24, then an adhesive backing material 23 is attached to the top surface of the release film 24. After being cut by the positioning die 8, the waste adhesive backing 27 and positioning waste 28 removed by cutting are taken away by the corresponding roller shaft 25. Here, the waste adhesive backing 27 is the unnecessary adhesive backing material 23 on the material 5, and the positioning waste 28 is the waste of the release film 24 remaining after cutting the positioning holes 10 on the material 5. Then, one side of the release film 24 is attached to the top surface of the cut material 5, and the obtained product is sent out from the circular cutting device 1. The product sent out from the circular cutting device 1 is sent into 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 pauses, the flat cutting die 14 is controlled to cut the material 5. During this process, the positioning posts 17 on the cutting member 15 in the flat cutting die 14 will insert into the positioning holes 10 on the material 5 and tension this part of the material 5, so that the cutting member 15 can accurately position the material 5 and complete the flat die cutting of the material 5. After the flat die cutting is completed, the obtained product is 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, and then the required functional adhesive device can be obtained.

[0054] The present utility model provides a manufacturing system for a functional adhesive device combining circular and flat cutting. This manufacturing system is used to cut the material 5 to be cut into a functional adhesive device with the required shape. It mainly includes 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.
