Description

Technical Field

[0001] This invention relates to the field of silicone cutting technology, and more particularly to an integrated cutting and slitting machine and a cutting and slitting method. Background Technology

[0002] Skip-cut processing technology is widely used in the manufacturing of automotive, electronics, and electrical products. In related technologies, skip-cut machines can be used to cut materials such as silicone sheets, conductive cloth, foam, diffuser sheets, reflective surfaces, double-sided tape, PET, PC, PE insulating paper, and copper / aluminum foil.

[0003] In related technologies, the process of cutting silicone rolls into silicone granules requires sequentially cutting the silicone rolls into silicone strips, then dividing the silicone strips into sheets of a preset size, which is called cutting. After that, the cut silicone sheets (multiple silicone strips are arranged on the support film) are skip-cut to cut out the corresponding silicone granules for user use. In related technologies, different cutting equipment or multiple cutting equipment are used to cut silicone rolls and skip-cut silicone granules separately. This requires a large equipment area and the production cost of multiple machines is high. At the same time, after cutting, the cut silicone sheets need to be transferred to the granulation process, resulting in long production line changeover time and low production efficiency. In other words, the skip-cutting machine for sheet cutting in related technologies cannot meet the needs of cutting and granulation in one machine.

[0004] There is still a lack of better technical solutions to address the problem that existing skip-cutting machines cannot simultaneously meet the needs of cutting and pelletizing silicone sheets. Summary of the Invention

[0005] In view of this, it is necessary to provide a cutting and granulation machine and a cutting and granulation method that can at least solve the problem that the cutting and granulation machines of the related technology cannot meet the needs of cutting and granulating silicone sheets at the same time.

[0006] In a first aspect, embodiments of this application provide a cutting and slitting integrated machine, including a machine base. The machine base is provided with a feeding mechanism, a first film changing mechanism, a cutting and slitting mechanism, a second film changing mechanism, a cutting mechanism, and a receiving mechanism. The cutting and slitting mechanism has a first receiving position and a second receiving position on its front and rear sides in the material feeding direction, respectively. The feeding mechanism is used to feed silicone rolls or cut silicone sheets onto a unwound carrier film and drive the carrier film to convey the silicone roll through the first film changing mechanism until the first receiving position, or drive the carrier film to convey the silicone sheet through the first film changing mechanism and the cutting and slitting mechanism until the second receiving position. The first film changing mechanism is used to replace the initial release film on the silicone roll with a target release film, wherein the target release film extends beyond the silicone roll. The two sides of the material width direction are to form a tear-off edge; during the cutting process, the second film changing mechanism is used to replace the carrier film supporting the silicone roll with a supporting film at the first receiving position, the cutting mechanism is used to asynchronously cut the silicone roll on the supporting film into silicone strips, the cutting mechanism cuts the supporting film supporting the silicone strips to a preset length to obtain silicone sheets, and the collecting mechanism is used to collect the silicone sheets; during the pelletizing process, the cutting mechanism is used to cut the silicone strips of the silicone sheet on the carrier film into silicone pellets, the second film changing mechanism is used to replace the carrier film carrying the silicone pellets with a bottom film at the second receiving position, the cutting mechanism cuts the bottom film to a preset length to obtain silicone pellet sheets, and the collecting mechanism is used to collect the silicone pellet sheets.

[0007] Secondly, embodiments of this application provide a method for silicone cutting and skipping, including the integrated cutting and skipping machine described in the first aspect. The method includes: docking the second film changing mechanism with the unloading mechanism at the first receiving position; unloading a carrier film through the unloading mechanism and pulling the silicone roll onto the unloaded carrier film; after the first film changing mechanism replaces the initial release film on the silicone roll with a target release film, driving the carrier film to convey the silicone roll covered with the target release film through the first film changing mechanism until the first receiving position; replacing the carrier film supporting the silicone roll with a support film at the first receiving position through the second film changing mechanism; and after the cutting and skipping mechanism asynchronously cuts the silicone roll on the support film into silicone strips, cutting the support film supporting the silicone strips to a preset length through the cutting mechanism. The process involves: cutting the silicone sheet to obtain a silicone sheet; collecting the silicone sheet using the receiving mechanism; docking the second film changing mechanism with the unloading mechanism at the second receiving position; rotating the collected silicone sheet by 90°; unloading the corresponding silicone sheet onto the unwinding carrier film; driving the carrier film through the unwinding mechanism to transmit the silicone sheet through the first film changing mechanism and the cutting mechanism until the second receiving position; cutting the silicone strip of the silicone sheet on the carrier film into silicone granules using the cutting mechanism; replacing the carrier film carrying the silicone granules with a base film at the second receiving position using the second film changing mechanism; cutting the base film carrying the silicone strip to a preset length using the cutting mechanism to obtain silicone granule sheets; and collecting the silicone granule sheets using the receiving mechanism.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: The embodiments of this application provide a cutting and granulating integrated machine and a cutting and granulating method, which adopts a feeding mechanism, a first film changing mechanism, a cutting and granulating mechanism, a second film changing mechanism, a cutting mechanism, and a receiving mechanism on the machine base. The cutting and granulating mechanism has a first receiving position and a second receiving position on the front and rear sides of the material feeding direction, respectively. According to the cutting and granulating operation status, the second film changing mechanism is connected to the feeding mechanism at the first receiving position and the second receiving position, respectively. The feeding mechanism unwinds the carrier film and feeds the silicone roll onto the unwound carrier film. After the first film changing mechanism replaces the initial release film on the silicone roll with the target release film, the carrier film is driven to convey the silicone roll covered with the target release film through the first film changing mechanism until the first receiving position. The second film changing mechanism replaces the carrier film supporting the silicone roll with a support film at the first receiving position, and the cutting and granulating mechanism asynchronously feeds the silicone roll on the support film. After being slit into silicone strips, the supporting film carrying the silicone strips is cut to a preset length by the cutting mechanism to obtain silicone sheets. The silicone sheets are then rotated 90° and fed one by one onto the unwinding film. The unwinding mechanism drives the film to convey the silicone sheets through the first film changing mechanism and the slitting and skipping cutting mechanism until the second receiving position. The slitting and skipping cutting mechanism cuts the silicone strips on the film into silicone granules. After the second film changing mechanism replaces the supporting film carrying the silicone granules with a base film at the second receiving position, the cutting mechanism cuts the base film carrying the silicone strips to a preset length to obtain silicone granule sheets. This solves the problem that skipping cutting machines in related technologies cannot simultaneously meet the needs of slitting and granulating silicone sheets, achieving multi-functionality, meeting the dual needs of slitting and granulating, reducing equipment costs and space occupation, and improving processing efficiency.

[0011] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

When a component is said to be "set on" another component, it can be directly set on the other component or may be interspersed with a component. When a component is said to be "fixed to" another component, it can be directly fixed to the other component or may be interspersed with a component.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0014] See Figures 1 to 12 This application provides a specific embodiment of a cutting and slitting integrated machine. The illustrated cutting and slitting integrated machine includes a machine base 100 housed within a frame (not shown in the figures). The machine base 100 is equipped with a feeding mechanism 200, a first film changing mechanism 300, a cutting and slitting mechanism 400, a second film changing mechanism 500, a cutting mechanism 600, and a receiving mechanism 700. The cutting and slitting mechanism 400 has a first receiving position 001 and a second receiving position 002 on its front and rear sides in the material feeding direction, respectively. In this embodiment, the receiving mechanism 700 includes, but is not limited to, a conveyor, such as a synchronous belt conveyor.

[0015] The feeding mechanism 200 is used to feed the silicone roll or the silicone sheet obtained by cutting onto the unwinding carrier film 01, and drive the carrier film 01 to convey the silicone roll through the first film changing mechanism 300 to the first receiving position 001, or drive the carrier film 01 to convey the silicone sheet through the first film changing mechanism 300 and the cutting skipping mechanism 400 to the second receiving position 002.

[0016] In this embodiment, the first receiving position 001 is located at the inlet end of the cutting mechanism 400, and the second receiving position 002 is located at the outlet end of the cutting mechanism 400 and close to the cutting mechanism 600.

[0017] The first film-changing mechanism 300 is used to replace the initial release film 02 on the silicone roll with the target release film 03, wherein the target release film 03 extends out of both sides of the silicone roll in the width direction to form a tear-off edge.

[0018] In this embodiment, after the initial release film 02 on the silicone roll is peeled off, a new release film, namely the target release film 03, is reapplied. When applying the target release film 03, the width of the target release film 03 is greater than the width of the silicone roll, so that both ends of the target release film 03 in the width direction are exposed. When the silicone roll is cut into silicone strips, each silicone strip will have a corresponding tear edge at both ends. The tear edge can be used to peel off the corresponding release film after the silicone sheet is cut out, so as to re-coat or retain the release film with the tear edge, so that the corresponding release film can be peeled off through the tear edge after the silicone strip is cut into silicone pellets. It should be noted that when the release film with the tear edge on the silicone strip is retained, when the silicone strip is cut into pellets, tear edges or tear openings will also be formed on other silicone pellets that are far away from the horizontal sides.

[0019] During the material cutting process, refer to Figure 5 The second film changing mechanism 500 is used to replace the carrier film 01 supporting the silicone roll with the support film 04 at the first receiving position 001. The cutting mechanism 400 is used to asynchronously cut the silicone roll on the support film 04 into silicone strips. The cutting mechanism 600 cuts the support film 04 supporting the silicone strips into silicone sheets according to a preset length to obtain silicone sheets. The collecting mechanism 700 is used to collect the silicone sheets.

[0020] In this embodiment, when cutting the silicone roll, since the silicone roll can be fed into the cutting mechanism 400 based on the silicone roll itself after being fed into the cutting mechanism 400, the carrier film 01 supporting the silicone roll is replaced at the first receiving position 001 before the silicone roll is fed into the cutting mechanism 400. This avoids cutting or folding the carrier film 01 during the cutting process and extends the service life of the carrier film 01. It can be understood that after replacing the carrier film 01 with the support film 04, even if the support film 04 is cut or folded, the impact is small. This is because when the support film 04 carries the silicone strip through the cutting mechanism 600, the cutting mechanism 600 will cut the support film 04 into pieces. Therefore, the resulting folding marks have little impact on the silicone sheet.

[0021] During the pelleting process, refer to Figure 6 The cutting mechanism 400 is used to cut the silicone strips of the silicone sheet located on the carrier film 01 into silicone granules. The second film changing mechanism 500 is used to replace the carrier film 01 carrying the silicone granules with the bottom film 05 at the second receiving position 002. The cutting mechanism 600 is used to cut the bottom film 05 to a preset length to obtain silicone granule sheets. The collecting mechanism 700 is used to collect the silicone granule sheets.

[0022] In this embodiment, when cutting silicone into pellets, since the silicone strip cannot be fed into the cutting mechanism 400 on its own, before the silicone sheet is fed into the cutting mechanism 400, the silicone sheet needs to be supported by the carrier film 01 and passed through the cutting mechanism 400 so that the cutting mechanism 400 asynchronously cuts the silicone strip into silicone pellets and conveys them out of the cutting mechanism 400. After the silicone pellets are cut, the silicone pellets arranged on the carrier film 01 need to be divided into silicone pellet sheets of corresponding sizes. At this time, the carrier film 01 is replaced with a bottom film 05 at the discharge end of the cutting mechanism 400 so that the silicone pellets are supported by the bottom film 05. After the bottom film 05 is cut, the silicone pellets are formed into silicone pellet sheets of a set size.

[0023] In the aforementioned integrated cutting and sizing machine, according to the cutting and pelletizing operation status, the second film changing mechanism 500 is connected to the unloading mechanism 200 at the first receiving position 001 and the second receiving position 002 respectively. The unloading mechanism 200 unloads the carrier film 01 and feeds the silicone roll onto the unwound carrier film 01. After the first film changing mechanism 300 replaces the initial release film 02 on the silicone roll with the target release film 03, the carrier film 01 is driven to convey the silicone roll covered with the target release film 03 through the first film changing mechanism 300 until it reaches the first receiving position 001. At the first receiving position 001, the second film changing mechanism 500 replaces the carrier film 01 supporting the silicone roll with a support film 04. After the cutting and skipping cutting mechanism 400 asynchronously cuts the silicone roll on the support film 04 into silicone strips, the cutting mechanism 600 cuts the support film 04 supporting the silicone strips to a preset length to obtain silicone sheets. The method involves rotating the received silicone sheet by 90°, then feeding the corresponding silicone sheets one by one onto the unwinding carrier film 01. The unwinding mechanism 200 drives the carrier film 01 to convey the silicone sheets through the first film changing mechanism 300 and the cutting mechanism 400 until the second receiving position 002. The cutting mechanism 400 cuts the silicone strips of the silicone sheets on the carrier film 01 into silicone granules. After the second film changing mechanism 500 replaces the carrier film 01 carrying the silicone granules with a base film 05 at the second receiving position 002, the cutting mechanism 600 cuts the base film 05 carrying the silicone strips to a preset length to obtain silicone granule sheets. This method solves the problem that the cutting machine in related technologies cannot simultaneously meet the needs of cutting and granulating silicone sheets. It achieves multi-purpose functionality, meets the dual functions of cutting and granulating, reduces equipment costs and space occupation, and improves processing efficiency.

[0024] It should be noted that in the actual cutting and pelletizing process, cutting and pelletizing are not continuous operations. Instead, a batch of silicone rolls is cut in one batch. After the entire batch of silicone rolls is cut, the docking point of the second film changing mechanism 500 is changed to carry out the subsequent pelletizing operation.

[0025] To achieve material cutting and pelletizing, refer to Figures 1 to 9In some embodiments, the cutting and skipping mechanism 400 includes a mounting base 41, on which an adjustable die assembly 42 is provided. A gantry tower 43 is positioned directly above the adjustable die assembly 42. The vertical arm 431 of the gantry tower 43 is connected to a linear guide rail 44 mounted on the vertical plate 11 of the machine base 100. The vertical arm 431 also passes through and exits the base plate 411 of the mounting base 41 and is connected to the skipping drive assembly 46 via an eccentric transmission device 45. The bottom end of the truss arm 432 of the frame 43 is provided with a cutter seat 47 facing the adjustable die assembly 42. A cutter 48 is installed at the bottom end of the cutter seat 47. The jump cut drive assembly 46 is used to drive the gantry tower 43 to jump vertically through the eccentric transmission device 45, so that the gantry tower 43 periodically drives the cutter seat 47 and the cutter 48 to move toward the die 421 of the adjustable die assembly 42, so as to cut the silicone roll material into strips or the silicone strip into pellets.

[0026] Understandably, with this configuration, the jump-cut drive assembly 46 drives the cutter holder 47 and the cutter 48 to move up and down through the eccentric transmission device 45. The cutter 48 on the cutter holder 47 moves up and down relative to the die 421, thereby enabling jump-cutting and slitting of the silicone roll at the advancing die 421 or asynchronous jump-cutting and pelletizing of the silicone strip at the advancing die 421.

[0027] To achieve the vertical runout of the transmission gantry tower 43, refer to Figures 8 to 9 In some embodiments, the eccentric transmission device 45 includes a mounting plate 451, a rotating shaft 452, an eccentric shaft 453, and a crank connecting rod 454. Two horizontally facing mounting plates 451 are provided on the bottom end of the base plate 411 away from the bottom of the adjustable die assembly 42. The rotating shaft 452 is horizontally positioned and movably connected to the two mounting plates 451. The eccentric shaft 453 is located at both axial ends of the rotating shaft 452, passing through and exiting the mounting plates 451. Each eccentric shaft 453 is also connected to a vertically positioned crank connecting rod 454. The end of the crank connecting rod 454 away from the connection to the eccentric shaft 453 is pivotally connected to the vertical arm 431. The rotating shaft 452 is also drively connected to the skip-cutting drive assembly 46. In this embodiment, the rotating shaft 452 is connected to the mounting plate 451 via a bearing, and the eccentric shaft 453 is connected to the crank connecting rod 454 via a bearing.

[0028] The jump-cut drive assembly 46 is used to drive the rotating shaft 452 to rotate, so that the rotating shaft 452 drives the eccentric shaft 453 to rotate eccentrically, and drives the crank connecting rod 454 to drive the gantry tower 43 to periodically jump vertically.

[0029] The gantry tower 43 periodically jumps vertically, causing the cutter seat 47 and the cutter 48 to move toward the die 421 of the adjustable die assembly 42.

[0030] Understandably, with this configuration, the jump-cut drive assembly 46 drives the rotating shaft 452 to rotate, thereby causing the rotating shaft 452 and the eccentric shaft 453 to rotate. The eccentric shaft 453 drives the crank connecting rod 454 to swing up and down, thereby causing the gantry tower 43 to periodically jump vertically. The cutter 48 on the cutter holder 47 moves up and down relative to the die 421, realizing the jump-cutting and slitting operation of the silicone roll at the advancing die 421 or the asynchronous jump-cutting and pelletizing operation of the silicone strip that has reached the die 421.

[0031] In some embodiments, reference Figures 8 to 10 The jump-cut drive assembly 46 includes a drive motor 461, a transmission belt, and a transmission wheel 462. The transmission wheel 462 is located on the rotating shaft 452, and the output shaft of the drive motor 461 is connected to the transmission wheel 462 via the transmission belt.

[0032] Understandably, with this configuration, the drive motor 461 drives the transmission wheel 462 on the rotating shaft 452 to rotate via the transmission belt, thereby driving the rotating shaft 452 and the eccentric shaft 453 to rotate. The eccentric shaft 453 drives the crank connecting rod 454 to swing up and down, thereby causing the gantry tower 43 to periodically jump vertically.

[0033] To achieve adjustable spacing between the die 421 and the cutter 48, refer to Figure 10 In some embodiments, the adjustable die assembly 42 further includes a pad 422, a wedge pusher 423, a pull rod 424, an elastic element 425, a die holder 426, and a die adjustment drive unit 427; the pad 422 is disposed on the base plate 411, and two wedge pushers 423 that can slide in the lateral direction are provided at both ends of the pad 422; the ball screw 4271 of the die adjustment drive unit 427 is connected to the wedge pusher 423 after passing through the vertical arm 431; the pull rod 425... 24. The vertically movable penetrating wedge pusher 423 and pad 422, the elastic element 425 is provided at one axial end of the pull rod 424 extending from the pad 422, the die holder 426 is provided above the wedge pusher 423 and is fixedly connected to the axial top end of the pull rod 424, the bottom end of the die holder 426 is provided with first inclined wedge surfaces 4261 on both sides, the end face of the wedge pusher 423 near the die holder 426 is provided with a second inclined wedge surface 4231 adapted to the first inclined wedge surface 4261, wherein, The drive motor 4272 of the tool adjustment drive unit 427 drives the corresponding ball screw 4271 to drive the inclined wedge push block 423 to slide laterally, so that the second inclined wedge surface 4231 pushes the first inclined wedge surface 4261 and raises the position of the tool holder 426. The elastic element 425 is used to drive the pull rod 424 downward and pull down the die holder 426 so that the raised die holder 426 is close to the two wedge push blocks 423.

[0034] Understandably, with this configuration, the drive motor 4272 drives the wedge pusher 423 to slide with high precision in the horizontal direction via the ball screw 4271. Simultaneously, the wedge pusher 423 and the die holder 426 form a wedge transmission mechanism through the cooperation of the second wedge surface 4231 and the first wedge surface 4261. This mechanism allows the horizontal movement of the wedge pusher 423 to drive the die holder 426 upwards, thereby raising the position of the die 421 and adjusting the relative position of the cutter 48 and the die 421. The stroke allows for the cutting of silicone sheets of different thicknesses. Simultaneously, the elastic element 425 drives the pull rod 424 downward, pulling the die holder 426 downward during the downward movement of the pull rod 424. This causes the die holder 426 to be pressed and fixed on the wedge push block 423, realizing stepless adjustment of the height of the die holder 426. This, in turn, enables stepless adjustment of the height of the die 421 installed on the die holder 426. This method is suitable for cutting workpieces of different specifications and processing requirements, improving the processing accuracy and versatility of the skip-cutting machine.

[0035] To achieve the conveying of silicone rolls or sheets to the cutting mechanism 400 and the cutting mechanism 600, refer to Figures 1 to 7 In some embodiments, the unloading mechanism 200 includes an unloading conveyor line 21, a carrier film unwinding assembly 22, a first traction assembly 23, and a second traction assembly 24. The unloading conveyor line 21 is located at the loading station 003 of the machine base 100 and is connected to the first traction assembly 23. The unwinding assembly 22 is located below the unloading conveyor line 21. The second traction assembly 24 is located between the cutting mechanism 400 and the cutting mechanism 600. The carrier film unwinding assembly 22 is located below the loading station 003 of the machine 100 and is used to unwind the carrier film 01 to the unwinding conveyor line 21 so that the carrier film 01 supports the silicone roll or the silicone sheet obtained by cutting at the loading station 003.

[0036] In this embodiment, the carrier film 01 unwound from the carrier film unwinding assembly 22 is guided by guide rollers to the unwinding conveyor line 21 and moves forward in the material feeding direction. When the carrier film 01 is unwound to the unwinding conveyor line 21, at the position of the unwinding conveyor line 21, the silicone roll material is fed (it can be fed by unwinding, the corresponding unwinding diagram is not shown) or the silicone sheet obtained by cutting is fed. At this time, the carrier film 01 is located in the lower layer, and the silicone roll material or silicone sheet material is located in the upper layer.

[0037] The feeding conveyor line 21 is used to cooperate with the first pulling component 23 to twist the material and convey the carrier film 01 carrying the silicone roll or silicone sheet to the first receiving position 001, or to convey the carrier film 01 carrying the silicone sheet through the cutting mechanism 400 to the second receiving position 002.

[0038] In this embodiment, the material feeding conveyor line 21 includes, but is not limited to, a conveyor, such as a synchronous belt conveyor.

[0039] In this embodiment, the first pulling component 23 is located in front of the feeding conveyor line 21. In practice, after the carrier film 01 passes through the first pulling component 23, the first pulling component 23 rolls the carrier film 01 forward. At the same time, the second winding component 51 of the second film changing component 500 pulls the carrier film 01 to roll it up, so that the carrier film 01 continues to move forward, at least carrying the silicone roll to the first receiving position 001. During the pelletizing process, the first pulling component 23 rolls the carrier film 01 forward, and at the same time, the second winding component 51 of the second film changing component 500 pulls the carrier film 01 to roll it up, so that the carrier film 01 carrying the silicone sheet is pulled through the cutting and skipping mechanism 400 until it reaches the second receiving position 002.
