[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] refer to Figure 1-Figure 11 , a cutting and slitting device for offset paper processing, comprising:

[0057] A work frame 100, on which a cutting platform 101 is provided, and on which a connecting box 102 is provided on the top of the cutting platform 101;

[0058] A plurality of feeding shafts 103 and a discharging shaft 104 are arranged on the cutting platform 101, and a cutting opening 105 is opened on the cutting platform 101 and is located between the feeding shaft 103 and the discharging shaft 104;

[0059] A baffle 106 is provided on the connecting box 102, and the baffle 106 extends to the top of the cutting platform 101, corresponding to the blanking shaft 104;

[0060] A frame 107 is disposed in the cutting platform 101, corresponding to the cutting opening 105, and a chain group is disposed on the frame 107, and a plurality of cutting blades 108 are disposed on the chain group;

[0061] The transmission component disposed in the frame 107 is used to drive the chain group to move along a predetermined path in the frame 107 to achieve the cutting operation;

[0062] The conveying component is arranged between the frame 107 and the loading shaft 103 and the unloading shaft 104, and is used to rotate the loading shaft 103 and the unloading shaft 104 in the same direction. The conveying component can rotate the loading shaft 103 and the unloading shaft 104 when the transmission component moves the chain group. The conveying component can stop the rotation of the loading shaft 103 and the unloading shaft 104 when the frame 107 leaves a predetermined position;

[0063] A release component provided between the baffle 106 and the frame 107, used to adjust the position of the baffle 106 after the frame 107 moves upward to a predetermined position and returns downward. When the frame 107 returns to the predetermined position, the baffle 106 returns to the initial position;

[0064] A positioning component provided between the frame 107 and the connecting box 102, used to adjust and fix the position of the offset paper when the frame 107 moves upward to a predetermined position;

[0065] The rotation speed of the unloading shaft 104 is higher than that of the loading shaft 103, and the conveying component can drive the loading shaft 103 to start rotating only after the unloading shaft 104 rotates to a preset angle;

[0066] By setting up the cutting platform 101, when in use, the cutting platform 101 can be connected to the cardboard conveyor belt of a production line, and the offset paper can be conveyed to the cutting platform 101 and received by the feeding shaft 103 thereon. When cutting, the transmission component can be used to drive the chain group to move along a predetermined path in the frame 107. In this process, the feeding shaft 103 and the unloading shaft 104 can be rotated in the same direction by the conveying component, and the offset paper that needs to be cut into strips can be conveyed to one side of the baffle 106. The baffle 106 is set to block the cardboard, and the offset paper can cover a part of the cutting port 105. When the feeding shaft 103 and the unloading shaft 104 rotate, the offset paper can be continuously When the paper is transported, if the offset paper is in an inclined state when it is conveyed to the cutting platform 101, a corner of the end face of the offset paper will first contact the baffle 106 to ensure that it can gradually adjust its position, and can effectively correct the position of the offset paper, ensuring that the end face of the offset paper can be parallel to the baffle 106, thereby ensuring that the offset paper remains flat during the cutting process, avoiding cutting errors caused by incorrect positions, and after the offset paper reaches the position of the baffle 106, the position of the frame 107 can be moved upward, so that the frame 107 drives the chain group and the cutting blade 108 therein to move, and the cutting blade 108 can enter the cutting port 105 and contact the offset paper, thereby accurately cutting the offset paper in strips. After the cutting blade 108 enters the cutting port 105 and contacts the offset paper, the transmission component continues to drive the chain group to move along the predetermined path, so that the cutting blade 108 cuts the surface of the offset paper in sequence. With the continuous movement of the chain group, multiple cutting blades 108 can work simultaneously to quickly complete multiple cutting operations of the offset paper. This multi-blade cutting method not only improves production efficiency, but also ensures uniformity of cutting width. In addition, when the frame 107 moves upward to a predetermined position, the rotation of the loading shaft 103 and the unloading shaft 104 can be stopped, and the provided positioning component can adjust and fix the position of the offset paper. On the basis of adjusting the cross section of the offset paper by blocking the baffle 106, the positioning component can also perform secondary positioning on the position of the offset paper to ensure that the end face can be parallel to the baffle 106, thereby further improving the cutting accuracy and avoiding the problem of uneven cutting caused by material sliding, so that the loading shaft 103 and the unloading shaft 104 are stopped, thereby ensuring that the offset paper remains stationary during the cutting process, avoiding cutting errors caused by the movement of the cardboard.Through this synchronous control mechanism, when the cutting blade 108 contacts the offset paper and completes the cutting, the position of the paperboard remains stable, ensuring the accuracy of each cutting line. Once the cutting is completed, the frame 107 drops to the initial position. During this process, the set release component can adjust the position of the baffle 106, allowing the baffle 106 to move upward for a distance. As the baffle 106 rises, the offset paper will be gradually released, and during the frame 107 reset and descend, the conveying component can continue to rotate the feeding shaft in the same direction. 103 and the unloading shaft 104, the rotation speed of the unloading shaft 104 is higher than that of the loading shaft 103, and the offset paper after stripping can be quickly transported out of the cutting platform 101 in the gap when the baffle 106 is lifted, ensuring that the offset paper is smoothly transported to the downstream process, avoiding jamming or retention, and making the rotation speed of the unloading shaft 104 higher than that of the loading shaft 103, and driving the rotation of the loading shaft 103 after the unloading shaft 104 rotates a preset angle, effectively avoiding the problem of the distance between the whole offset paper and the offset paper after stripping being too close. This design ensures that during the cutting process, the baffle 106 can effectively block the offset paper and prevent it from overlapping with the uncut part after stripping, thereby avoiding possible cutting errors and confusion of the offset paper. Through a reasonable rotation sequence, the present application can ensure that the operation of the loading shaft 103 does not interfere with the separated offset paper while the unloading shaft 104 drives the offset paper after stripping to move out of the cutting area quickly. This not only ensures the cutting quality, but also improves the safety and efficiency of the operation, and further optimizes the stability of the entire production process. The advantage of this design is that through the linkage system, the orderly connection between each link is ensured, and finally efficient and accurate offset paper cutting and transportation are achieved. The offset paper cutting system of this application realizes efficient and accurate strip cutting through the innovative cutting platform 101 design. Through the chain group and multi-blade cutting mechanism, the stable positioning and high-quality cutting of the offset paper are ensured, which significantly improves the production efficiency. The design scheme of this application not only solves the deficiencies in the prior art, but also provides reliable technical guarantee for the cutting and subsequent processing of offset paper.

[0067] As a further solution of the present invention, the chain set includes a plurality of chain shafts 109 rotatably connected to the frame 107, two sprockets 110 are provided on the chain shafts 109, chains 111 are provided on the two sets of sprockets 110, a plurality of connecting rods 112 are connected between the two chains 111, and the cutting blades 108 are connected to the connecting rods 112;

[0068] By setting the chain 111, the precise movement of the cutting blade 108 can be effectively achieved. The design of the chain 111 ensures that the blade moves evenly and continuously along the predetermined path during the cutting process, thereby achieving efficient strip cutting operations; in addition, compared with wire cutting, laser cutting, ultrasonic vibration cutting, long blade downward cutting and traditional circular blade rotary cutting in the prior art, wire cutting is usually used in high-precision occasions such as metal processing. It has high cutting accuracy, but slow processing speed, and wire cutting equipment has high requirements for the operating environment, such as replacement and maintenance of coolant and electrode wire. In addition, the application effect of wire cutting equipment on soft materials such as offset paper is not good, and it is easy to cause damage or cracking of the material surface. In contrast, the chain group cutting of the present application is suitable for multi-layer and thicker materials such as offset paper, which can achieve fast and continuous strip cutting, improve production efficiency, and reduce damage to the material; laser cutting has the advantages of high precision and non-contact, and is suitable for thin and delicate materials. However, laser cutting has limited effect on thicker materials such as offset paper, especially in the application of high-strength, multi-layer paperboard, where the cutting efficiency is low, and laser cutting may cause the edge of the material to be burned or deformed, affecting the quality of the final product. The chain group cutting of the present application directly contacts the material through the mechanical blade, which can cut thicker offset paper at one time, and multiple blades work synchronously, without generating a heat-affected zone, and the cutting edge is smooth. Ultrasonic vibration cutting achieves material segmentation through high-frequency vibration, which is suitable for cutting soft materials or composite materials, but for thicker or tougher materials such as offset paper, ultrasonic cutting may have insufficient vibration, resulting in uneven cutting or uneven cross-section. In addition, ultrasonic cutting equipment is complex and has high maintenance costs, and is suitable for small-scale production. The chain group cutting of the present application can efficiently slit large-scale offset paper, and the equipment structure is relatively simple, the maintenance cost is low, and it is suitable for large-scale industrial production. The rotary cutting of the circular blade is a common cutting method, but due to the rotation path and speed limit of a single blade, after the cutting circular blade reaches the predetermined position, it is necessary to move the cutting circular blade along the predetermined path. In this process, the offset paper will be pushed, and the problem of uneven cross section may occur, and the cutting efficiency is low; the downward pressure cutting of the cutting blade 108 is also a common cutting method, which is usually used for cutting thicker materials. It applies pressure to the material through the vertical movement of the blade up and down to achieve the cutting operation. This cutting method is widely used in the processing of materials such as cardboard, leather, and plastic, and is particularly suitable for simple, linear cutting. However, compared with the chain group cutting of the present application, the downward pressure cutting of the blade also has some limitations. The advantage of the downward pressure cutting is linear cutting, but its structure determines that it is more suitable for cutting small-area materials and cannot effectively process large-format materials. When cutting large-size offset paper, the cutting efficiency and flexibility are low.The chain group cutting of the present application is suitable for long and wide materials, and can complete large-area strip cutting in a short time, adapting to more complex production needs. In the downward pressure cutting, the blade needs to apply vertical pressure to the material, which requires high strength of the blade, and the blade is easy to wear under long-term high-intensity use. In contrast, the chain group cutting of the present application adopts a method of continuous movement of multiple blades, and the cutting load between the blades is shared, which can extend the service life of the blade, reduce the maintenance frequency and replacement cost, and in the downward pressure cutting, the cutting effect depends on the pressure applied by the blade. If the pressure is too large, it may cause deformation or indentation of the material; if the pressure is too small, the cutting effect is not ideal. The chain group cutting can maintain the constant pressure of the blade on the material during the cutting process through precise transmission control, ensure stable cutting effect, and avoid damage to the material. The chain group cutting system of the present application solves the problems of low efficiency, narrow application range, and easy wear of the blade in the downward pressure cutting by the synchronous operation and continuous movement of multiple blades. The chain group cutting method can significantly improve efficiency in mass production, ensure cutting accuracy and uniformity, and is particularly suitable for offset paper production lines that require efficient slitting, showing significant automation and reliability advantages.

[0069] As a further solution of the present invention, the release component includes a first connecting rod 200 connected to the frame 107, a reel 201 is rotatably connected in the connecting box 102, a traction rope 202 is wound on the reel 201, one end of the traction rope 202 is connected to the baffle 106, a first spring 203 is connected between the baffle 106 and the connecting box 102, a first rack 204 is connected to the first connecting rod 200, a first gear 205 meshing with the first rack 204 is connected to the reel 201, and a ratchet mechanism 206 is provided between the first gear 205 and the reel 201;

[0070] By setting the first connecting rod 200, when the frame 107 moves upward to cut the offset paper, the first connecting rod 200 can drive the first rack 204 to move upward and mesh with the first gear 205. Since a ratchet mechanism 206 is provided between the first gear 205 and the reel 201, the first gear 205 idles outside the reel 201 at this time and does not affect the angle of the reel 201. When the frame 107 moves upward to complete the cutting work and then resets downward, the first rack 204 moves downward to allow the first gear 205 to rotate. The rotation of the first gear 205 can rotate the reel 201 through the ratchet mechanism 206, and reel in the traction rope 202, which can lift the position of the baffle 106 and compress the first spring 203 to generate potential energy. This design allows the offset paper that has been striped to be released smoothly through the gap between the baffle 106 and the cutting platform 101. When the frame 107 is reset and moved downward to the initial position, the first rack 204 leaves the first gear 205, and the first spring 203 releases its stored potential energy, prompting the baffle 106 to reset and continue to block the uncut offset paper. This design ensures the safety and efficiency of the cutting process, so that the cut offset paper can be quickly removed, while the uncut part is still effectively blocked, avoiding the intersection and confusion of materials. Through this ingenious release mechanism, the cutting operation can be completed quickly and accurately, improving the overall efficiency of the production line. The design of the release component not only improves the stability of the equipment, but also effectively reduces the intervention of the operator, ensuring the safety and smoothness of the operation process. Overall, the mechanism makes the cutting and release process more efficient and coordinated through the cooperation of a series of linkage devices, providing reliable guarantee for the subsequent processing of offset paper.

[0071] As a further solution of the present invention, the conveying component includes a first synchronous belt 207 connected between every two adjacent loading shafts 103, a second synchronous belt 208 is connected between every two adjacent unloading shafts 104, a loading roller 209 and an unloading roller 210 are provided in the cutting platform 101, the diameter of the unloading roller 210 is larger than that of the loading roller 209, a third synchronous belt 211 is connected between the loading roller 209 and one of the loading shafts 103, and a fourth synchronous belt 212 is connected between the unloading roller 210 and the unloading shaft 104;

[0072] By setting the loading roller 209 and the unloading roller 210, the loading roller 209 and the unloading roller 210 can be rotated synchronously and in the same direction during use. This design ensures that the offset paper can be transported stably and improves the transport efficiency. The diameter difference between the loading roller 209 and the unloading roller 210 enables the unloading roller 210 to provide stronger traction. By using the different diameter ratios between the unloading roller 210 and the loading roller 209, the rotation speed of the unloading shaft 104 can be greater than the loading shaft 103, ensuring that the stripped offset paper can be smoothly removed from the cutting platform 101, avoiding the jamming or retention of the material during the transport process. In summary, the combined design of the loading roller 209 and the unloading roller 210 not only optimizes the transport method of the offset paper, but also improves the overall cutting accuracy and production efficiency during the cutting process. This innovative conveying system design provides reliable support for subsequent processing procedures and ensures the smoothness and efficiency of the production process.

[0073] As a further solution of the present invention, the conveying component also includes a transmission shaft 213 rotatably connected to the frame 107, a fifth synchronous belt 214 is connected between the transmission shaft 213 and one of the chain shafts 109, a worm 215 is connected to both ends of the transmission shaft 213, and a worm wheel 216 adapted to the worm 215 is connected to the upper and lower material rollers 209 and 210;

[0074] By setting a transmission shaft 213, when the transmission component drives multiple chain shafts 109 to rotate so that the cutting blade 108 moves along a predetermined path in the frame 107, the transmission shaft 213 can be rotated through the fifth synchronous belt 214. In the initial state, the worm 215 is meshed with the worm wheel 216. The rotation of the transmission shaft 213 can make the loading roller 209 and the unloading roller 210 rotate synchronously and in the same direction through the worm wheel 216 and the worm 215, thereby realizing the loading and unloading of the offset paper. The tooth depths of the worm wheel 216 and the worm 215 are deeper. When the frame 107 moves upward, the worm 215 gradually separates from the worm wheel 216. When the worm 215 completely separates from the worm wheel 216, the unloading shaft 104 and the loading shaft 103 can stop rotating. After the cutting work is completed, when the frame 107 moves downward to reset, the worm 215 Engaged with the worm gear 216, the transmission shaft 213 can transmit power to the loading roller 209 and the unloading roller 210, and can drive the loading shaft 103 and the unloading shaft 104 to rotate. At this time, the baffle 106 moves upward to leave the surface of the cutting platform 101 and creates a gap for the offset paper to pass through. After the worm 215 is initially engaged with the worm 215, the worm 215 still has a certain space to fall until the frame 107 is reset to its original position, the first rack 204 is disengaged from the first gear 205, and the baffle 106 can be reset to block the offset paper again. Overall, the design of this conveying component not only improves the loading and unloading efficiency of the offset paper through the ingenious combination of the worm gear 216 and the worm 215, but also optimizes the stability of the cutting process, effectively avoids cutting errors, and ensures the smooth operation of the offset paper during cutting and conveying.

[0075] As a further solution of the present invention, the conveying component further includes a connecting ring 217 connected to the feeding roller 209, a connecting cavity 218 is provided in a worm gear 216 located on the feeding roller 209, a first connecting block 219 is connected to the outer wall of the connecting ring 217, a plurality of second connecting blocks 220 are connected in the connecting ring 217, and a second spring 221 is connected between the first connecting block 219 and the second connecting block 220;

[0076] By providing the first connecting block 219 and the second connecting block 220, when the transmission shaft 213 rotates through the worm 215 to drive the worm wheel 216 to rotate, the unloading roller 210 will immediately rotate, and the worm wheel 216 on the loading roller 209 will idle on the loading roller 209 for a certain angle until the second connecting block 220 contacts the first connecting block 219, that is, after the unloading roller 210 rotates by a preset angle, the loading roller 209 starts to rotate, so as to provide a rotation interval, ensure that the stripped offset paper can be quickly separated from the uncut offset paper, achieve better unloading, and avoid the problem that the subsequent offset paper cannot be blocked. After the subsequent worm 215 and the worm wheel 216 are disengaged, the worm wheel 216 can be reset by the force of the second spring 221, so that the first connecting block 219 and the second connecting block 220 are spaced a certain distance again to prepare for the next rotation.

[0077] As a further solution of the present invention, the positioning component includes a second connecting rod 300 connected to the first connecting rod 200, the second connecting rod 300 is connected to a second rack 301 extending into the connecting box 102, a positioning plate 302 is slidably connected in the connecting box 102, the bottom of the positioning plate 302 is connected to two positioning bars 303 extending to the top of the cutting platform 101, the two sides of the positioning plate 302 are respectively connected to third racks 304, and a second gear 305 is provided between the second rack 301 and the third rack 304;

[0078] By setting the second connecting rod 300, when the frame 107 moves upward, the first connecting rod 200 moves synchronously with the second connecting rod 300, and the position of the baffle 106 remains unchanged at this time, while the position of the positioning plate 302 is affected by the second rack 301, the second gear 305 and the third rack 304, and moves downward. The positioning strip 303 at the bottom can contact the offset paper to position the offset paper. This design ensures the precise positioning of the offset paper during the cutting process and avoids the problem of inaccurate cutting caused by the position deviation of the offset paper due to the movement of the cutting blade 108 when the cutting blade 108 cuts the offset paper.

[0079] As a further solution of the present invention, a third spring 306 is connected between the positioning bar 303 and the positioning plate 302;

[0080] By providing the third spring 306, an elastic connection between the positioning strip 303 and the positioning plate 302 can be achieved, ensuring that the positioning strip 303 can flexibly adapt to the height change of the offset paper during the cutting process. This design allows the positioning strip 303 to have a certain deformation ability when subjected to external force, thereby effectively reducing the pressure on the offset paper and preventing it from being damaged or deformed due to excessive pressure.

[0081] As a further solution of the present invention, the positioning component also includes a positioning horizontal bar 307 slidably connected to the inside of the work frame 100, a fourth spring 308 is connected between the positioning horizontal bars 307, a folding rod 309 is connected to the bottom of the positioning plate 302, a first pressure rod 310 is rotatably connected to the bottom of the folding rod 309, a second pressure rod 311 is rotatably connected to the bottom of the first pressure rod 310, a fifth spring 312 is connected between the first pressure rod 310 and the second pressure rod 311, and a connecting bar 313 rotatably connected to the second pressure rod 311 is connected to the positioning horizontal bar 307;

[0082] By providing the folding rod 309, when the positioning plate 302 moves downward, the positions of the first pressure rod 310 and the second pressure rod 311 can be pressed by the folding rod 309, so that the positioning bar 307 can be forced to move toward the offset paper to contact and move the position of the offset paper. In this process, the fourth spring 308 and the fifth spring 312 effectively provide the necessary elastic support to ensure that the positioning bar 307 has sufficient flexibility when contacting the offset paper to avoid excessive pressure and potential damage to the offset paper. This design effectively improves the positioning accuracy of the offset paper, ensures that the offset paper can maintain a good position relationship in the subsequent processing steps, and ensures the efficient operation of the production line.

[0083] As a further solution of the present invention, a motor 113 is connected to one side of the frame 107, a drive shaft of the motor 113 is connected to one of the chain shafts 109, an electric push rod 114 is connected to the cutting platform 101, and a telescopic shaft of the electric push rod 114 is connected to the bottom of the frame 107;

[0084] By setting the motor 113, the machine can provide a stable and continuous power source to drive the rotation of the chain shaft 109, thereby ensuring that the cutting blade 108 can efficiently cut along the predetermined path. The selection and configuration of the motor 113 ensures the response speed and cutting accuracy of the system, adapts to offset paper of different thicknesses and materials, and thus improves the overall production efficiency. The design of the electric push rod 114 allows the frame 107 to move up and down, and accurately controls the cutting depth and position. Through the extension and retraction of the electric push rod 114, the frame 107 can quickly adjust its height during the cutting process to adapt to the needs of offset paper of different specifications. This design not only improves the flexibility of operation, but also reduces the workload of manual adjustment and improves safety.

[0085] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
