[0034] The implementation mode of the present invention is described below in conjunction with relevant embodiments. The implementation mode of the present invention is not limited to the following embodiments, and the present invention relates to relevant necessary components in the technical field, which should be regarded as the known technology in the technical field and can be known and mastered by the technical personnel in the technical field.

[0035] like Figures 1 to 8As shown, a release paper slitting device capable of automatically cutting materials comprises a frame 1, a rotating frame 2 and a slitting assembly 3, wherein the rotating frame 2 comprises support discs 21 symmetrically arranged on the frame 1 and a connecting shaft 22 axially penetrating between the support discs 21, the slitting assembly 3 is distributed in a ring array between the support discs 21 and connected to the corresponding support discs 21 at both ends, the slitting assembly 3 comprises a slitting knife group 32 arranged in parallel front and back, a fan-shaped mounting block 31 movably sleeved on both ends of the slitting knife group 32, and a slitting bottom roller 33 arranged directly below the support disc 21 and tangent to the blade of the slitting knife group 32, a fastening structure 4 is provided on the support disc 21, and the fan-shaped mounting block 31 is detachably mounted on the support disc 21 through the fastening structure 4, a first driving assembly 5 fixedly connected is provided on the left outer wall of the frame 1, and a second driving assembly 6 fixedly connected is provided on the right outer wall of the frame 1, and the first driving assembly 5 and the second driving assembly 6 are respectively connected to the two ends of the slitting knife group 32 by transmission.

[0036] In the structure of the present invention, a unwinding assembly 7 is installed on the feed side of the slitting assembly 3. The unwinding assembly 7 structurally includes an unwinding roller 71 installed on the frame 1 and an unwinding motor 72 transmission-connected to the unwinding roller 71. The power output shaft of the unwinding motor 72 is connected to one end of the unwinding roller 71.

[0037] The rotating frame 2 of the present invention is the main structure that connects and supports the slitting assembly 3, and can rotate under the drive of the first drive motor 23. The rotation of the rotating frame 2 allows the slitting assembly 3 to switch between different workstations, thereby facilitating the replacement or repair of the damaged slitting knife group 32. The supporting disc 21 of the rotating frame 2 is used to install the slitting assembly 3, and the connecting shaft 22 plays a role of connection and transmission. The supporting disc 21 provides a platform for installing the slitting assembly 3. The supporting disc 21 is provided with a fan-shaped mounting groove 211 and a mounting card groove 212, which are used to cooperate with the fan-shaped mounting block 31 for installation to ensure that the slitting knife group 32 can be stably fixed on the supporting disc 21. The connecting shaft 22 passes through and is connected to the center position of the supporting disc 21, and both ends are rotatably connected to the frame 1. Driven by the first drive motor 23, the connecting shaft 22 can drive the rotating frame 2 to rotate as a whole.

[0038] The slitting assembly 3 of the present invention is structurally provided with a slitting knife group 32, a fan-shaped mounting block 31 and a slitting bottom roller 33 arranged in parallel in front and back. The slitting knife group 32 is installed on the support disc 21 through the fan-shaped mounting block 31, and the slitting bottom roller 33 is located directly below the support disc 21 and is tangent to the blade of the slitting knife group 32 to cooperate with the slitting knife group 32 to complete the slitting action. The slitting knife group 32 includes a first slitting knife group 321 and a second slitting knife group 322, which are respectively installed on the support disc 21 through the fan-shaped mounting block 31. Each slitting assembly includes a first slitting knife group 321 and a second slitting knife group 322. The rotating shaft 324 and a plurality of cutting circular knives 323 are installed on the first rotating shaft 324 at equal intervals. The fan-shaped mounting block 31 is used to connect the slitting knife group 32 and the supporting disc 21. It is detachably mounted on the supporting disc 21 through the fastening structure 4, which is convenient for the installation, disassembly and replacement of the slitting knife group 32. The slitting bottom roller 33 is located directly below the supporting disc 21 and is tangent to the blade of the slitting knife group 32. During the slitting process, the slitting bottom roller 33 supports and guides the release paper to ensure that the release paper can pass through the slitting knife group 32 smoothly and complete the slitting action.

[0039] The fastening structure 4 of the present invention is used to firmly mount the fan-shaped mounting block 31 on the supporting disc 21 to ensure that the slitting knife group 32 will not loosen or fall off during the slitting process. The fastening structure 4 tightly connects the fan-shaped mounting block 31 and the supporting disc 21 together through the fixing screws 44. The first driving assembly 5 and the second driving assembly 6 are respectively located on the left and right sides of the frame 1, and are used to transmit and connect the two ends of the slitting knife group 32. The first driving assembly 5 and the second driving assembly 6 can adjust the distance between the cutting circular knives 323 in the slitting knife group 32, so that the first slitting knife group 321 and the second slitting knife group 322 can be staggered, thereby processing two types of slitting release papers with different width specifications in one cutting. The unwinding assembly 7 is located on the feeding side of the slitting assembly 3, and is used to place and convey the release paper to be slitting. The rotation speed of the unwinding roller 71 can be controlled by driving the unwinding motor 72, thereby realizing continuous conveying of the release paper.

[0040] As one of the preferred embodiments of the present invention, Figure 1 , Figure 2 and Figure 8 As shown, the connecting shaft 22 passes through and is connected to the center position of the supporting disc 21, and both ends of the connecting shaft 22 are respectively rotatably connected to the frame 1. A first driving motor 23 installed on the frame 1 is provided above the second driving assembly 6, and the right end of the connecting shaft 22 is connected to the power output shaft of the first driving motor 23.

[0041] The first drive motor 23 is installed on the frame 1, and its power output shaft is connected to the right end of the connecting shaft 22. When the first drive motor 23 is started, the power generated by the first drive motor 23 will be directly transmitted to the connecting shaft 22 through the power output shaft. The connecting shaft 22 is connected through the center position of the supporting disc 21. Since both ends of the connecting shaft 22 are rotatably connected to the frame 1, and the right end of the connecting shaft 22 is connected to the power output shaft of the first drive motor 23, when the first drive motor 23 is started, the connecting shaft 22 will drive the supporting disc 21 to rotate together. Since the rotating frame 2 includes a supporting disc 21 symmetrically arranged on the frame 1, when the supporting disc 21 rotates, the entire rotating frame 2 will also rotate accordingly. In this way, the slitting assembly 3 installed on the rotating frame 2 can be switched between different workstations.

[0042] As one of the preferred embodiments of the present invention, Figure 4 , Figure 5 and Figure 7 As shown, the support disc 21 is provided with a fan-shaped mounting groove 211 for installing the fan-shaped mounting block 31, and the inclined inner walls on the front and rear sides of the fan-shaped mounting groove 211 are provided with mounting card grooves 212, and the inclined surfaces on the front and rear ends of the mounting fan-shaped mounting block 31 are provided with mounting card strips 311 that can slide and engage with the mounting card groove 212.

[0043] The mutual sliding engagement between the mounting slot 212 and the mounting strip 311 can ensure that the fan-shaped mounting block 31 can be stably and detachably mounted on the supporting disc 21. The mounting slot 212 is arranged on the inclined inner walls on the front and rear sides of the fan-shaped mounting slot 211 of the supporting disc 21, and the mounting strip 311 is arranged on the inclined surfaces at the front and rear ends of the fan-shaped mounting block 31. When the fan-shaped mounting block 31 is placed in the fan-shaped mounting slot 211, the mounting strip 311 will slide along the inclined inner wall of the mounting slot 212 until they are completely engaged together. In this process, the mounting slot 212 plays a role of positioning and guiding, ensuring that the fan-shaped mounting block 31 can be accurately mounted on the supporting disc 21. When the slitting knife group 32 needs to be replaced or repaired, the fan-shaped mounting block 31 only needs to be slid out of the supporting disc 21.

[0044] In addition, the interaction between the mounting slot 212 and the mounting strip 311 also enhances the stability of the fan-shaped mounting block 31 on the supporting disc 21. During the slitting process, the slitting knife group 32 will be subjected to greater force and vibration, but the engagement between the mounting slot 212 and the mounting strip 311 can effectively prevent the fan-shaped mounting block 31 from loosening or falling off, thereby ensuring the smooth progress of the slitting process.

[0045] As one of the preferred embodiments of the present invention, Figures 1 to 5As shown, the slitting knife group 32 includes a first slitting knife group 321 and a second slitting knife group 322 which are sequentially arranged in a clockwise direction along the supporting disc 21, and the first slitting knife group 321 and the second slitting knife group 322 are respectively connected to the edge positions of both ends of the mounting fan-shaped mounting block 31, and the first slitting knife group 321 and the second slitting knife group 322 have the same structure, and both include a first rotating shaft 324 and a plurality of cutting circular knives 323 equidistantly installed on the first rotating shaft 324, and the two ends of the first rotating shaft 324 are respectively rotatably connected to the corresponding fan-shaped mounting block 31, a second adjusting channel 328 is provided inside the left end shaft rod of the first rotating shaft 324, a first gear 326 which is sleeved and fixedly connected is provided outside the left end shaft rod of the first rotating shaft 324, a first adjusting channel 327 is provided inside the right end shaft rod of the first rotating shaft 324, and a limiting ring 325 which is sleeved and fixedly connected is provided outside the left end shaft rod of the first rotating shaft 324.

[0046] The slitting knife group 32 mainly includes a first slitting knife group 321 and a second slitting knife group 322. The first slitting knife group 321 and the second slitting knife group 322 are completely identical in structure. The first slitting knife group 321 and the second slitting knife group 322 both include a first rotating shaft 324 and a plurality of cutting circular knives 323 installed on the first rotating shaft 324 at equal intervals. The first rotating shaft 324 plays a supporting and transmission role. Driven by the third driving motor 57 and the second gear 56 of the first driving assembly 5, the cutting action is realized. The left end shaft of the first rotating shaft 324 is provided with a second adjustment channel 328, while the right end shaft is provided with a first adjustment channel 327. The existence of these two adjustment channels allows the spacing of the slitting assembly 3 to be adjusted by the first driving assembly 5 and the second driving assembly 6, thereby changing the position of the cutting circular knives 323 on the slitting bottom roller 33.

[0047] A first gear 326 and a stop ring 325 are sleeved and fixedly connected to the outside of the left end of the first rotating shaft 324. The first gear 326 is used to mesh with the second gear 56 for transmission, thereby receiving power from the first driving assembly 5, and the stop ring 325 plays a role in limiting the axial movement of the first gear 326, so as to prevent the first rotating shafts 324 of the first slitting knife group 321 and the second slitting knife group 322 from being separated from the fan-shaped mounting block 31 when the first slitting knife group 321 and the second slitting knife group 322 adjust the position of the cutting circular knife 323 on the slitting bottom roller 33 in the horizontal direction.

[0048] When the slitting knife group 32 is in working state, the first drive motor 23 drives the supporting disc 21 to rotate through the connecting shaft 22, thereby driving the slitting knife group 32 to rotate together. When the slitting knife group 32 runs above the slitting bottom roller 33, the lifting electric cylinder 333 of the slitting bottom roller 33 will drive it to rise in the lifting channel 334, so that the surface of the slitting bottom roller 33 is tangent to the cutting circular knife 323. At this time, the cutting circular knife 323 will be driven by the third drive motor 57 and the second gear 56, and the slitting bottom roller 33 will be driven by the second drive motor 335 to cooperate with each other to cut the passing release paper.

[0049] Since the cutting circular knives 323 of the first cutting knife group 321 and the second cutting knife group 322 are arranged in an alternating manner, they can process two types of cut release papers with different width specifications in one cutting process, thereby meeting the diversified width specifications of release paper slitting. When a cutting circular knife 323 in the cutting knife group 32 is damaged or worn, the fan-shaped mounting block 31 can be removed from the supporting disc 21 by disassembling the fastening structure 4, and then the damaged cutting circular knife 323 can be replaced or repaired, making the maintenance work more convenient and quick, reducing downtime and production costs.

[0050] As one of the preferred embodiments of the present invention, Figures 1 to 3 As shown, the slitting bottom roller 33 is provided with a second rotating shaft 331, and the frame 1 is provided with a lifting channel 334 at the corresponding positions at both ends of the second rotating shaft 331, and the two ends of the second rotating shaft 331 are placed in the lifting channel 334. The slitting bottom roller 33 is respectively provided on the left and right outer walls of the frame 1 corresponding to the mounting frames 332 that are rotatably connected to the end portions of the second rotating shaft 331, and a lifting electric cylinder 333 is connected to the bottom of the mounting frame 332. A second driving motor 335 connected to the second rotating shaft 331 is installed on the mounting frame 332 on the same side as the second driving assembly 6, and guide rollers 336 rotatably connected to the frame 1 are symmetrically provided on the front and rear sides of the slitting bottom roller 33.

[0051] The slitting bottom roller 33 cooperates with the lifting channel 334 on the frame 1 through the second rotating shaft 331 to realize its lifting movement in the vertical direction. When the slitting knife group 32 runs above the slitting bottom roller 33, the lifting electric cylinder 333 of the slitting bottom roller 33 will drive it to rise in the lifting channel 334, so that the surface of the slitting bottom roller 33 is tangent to the blade of the slitting knife group 32. At the same time, the front and rear sides of the slitting bottom roller 33 are symmetrically provided with guide rollers 336 rotatably connected to the frame 1, and the lifting function of the slitting bottom roller 33 is realized. It can also adapt to release papers of different thicknesses. The guide roller 336 ensures that the release paper can move along the correct path during the cutting process to avoid deviation or wrinkles. A second drive motor 335 connected to the second rotating shaft 331 is installed on the mounting frame 332 on the same side as the second drive assembly 6. When the second drive motor 335 is started, the second drive motor 335 drives the slitting bottom roller 33 to rotate, thereby cooperating with the first slitting knife group 321 and the second slitting knife group 322 to slit the release paper.

[0052] As one of the preferred embodiments of the present invention, Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the fastening structure 4 includes a second arc-shaped main body slide groove 312 arranged on the outer surface of the fan-shaped mounting block 31 and a second arc-shaped side slide groove 313 respectively arranged on the left and right side walls of the second arc-shaped main body slide groove 312, a first arc-shaped main body slide groove 42 arranged at the front and rear ends of the fan-shaped mounting block 31 and located on the circumferential surface of the support disk 21, and a first arc-shaped side slide groove 421 arranged on the left and right side walls of the first arc-shaped main body slide groove 42, the second arc-shaped main body slide groove 312 is connected to the first arc-shaped main body slide groove 42, the first arc-shaped side slide groove 421 is connected to the second arc-shaped side slide groove 313, and the fastening structure 4 includes a second arc-shaped main body slide groove 312 and a second arc-shaped side slide groove 313. The fixed structure 4 is provided with an arc-shaped fixing plate 41 which can slide and cooperate in the second arc-shaped main body slide groove 312 and the first arc-shaped main body slide groove 42, and the left and right sides of the arc-shaped fixing plate 41 are provided with an arc-shaped side slide groove 421 and an arc-shaped slide bar 411 which slides and cooperates in the second arc-shaped side slide groove 313, and the front and rear end surfaces of the arc-shaped fixing plate 41 are provided with second threaded holes 43, and the first arc-shaped side slide groove 421 is provided with a first threaded hole 412 corresponding to the position of the second threaded hole 43, and the front and rear ends of the arc-shaped fixing plate 41 are provided with fixing screws 44 threadedly connected to the first threaded hole 412 and the second threaded hole 43.

[0053] When the fan-shaped mounting block 31 is mounted on the supporting disc 21 through the fastening structure 4, the fan-shaped mounting block 31 is placed into the fan-shaped mounting groove 211, so that the second arc-shaped main body slide groove 312 is gradually aligned with and connected to the first arc-shaped main body slide groove 42, and the second arc-shaped side slide groove 313 corresponds to the first arc-shaped side slide groove 421. Then, the arc-shaped fixing plate 41 in the first arc-shaped main body slide groove 42 is slid along the slide groove formed by the first arc-shaped main body slide groove 42 and the second arc-shaped main body slide groove 312, and the arc-shaped fixing plate 41 is fixed to the first arc-shaped main body slide groove 42.
