Description

Technical Field

[0001] This invention relates to the field of printing plate production technology, and in particular to a high-precision flying shear cutting device for offset printing plates based on online length adjustment. Background Technology

[0002] In continuous sheet metal processing production lines, flying shears are key equipment for achieving dynamic, fixed-length shearing, and are widely used in industries such as metallurgy, automotive, home appliances, and packaging. With the ever-accelerating pace of production, sheet metal flying shears are developing towards higher speeds, continuous operation, and higher precision.

[0003] In practical applications, existing flying shear systems generally lack the ability to adaptively correct mechanical deviations when correcting printing plates. Furthermore, flying shears are subject to various disturbances during long-term continuous operation, leading to a gradual deterioration in cutting accuracy. Consequently, the system cannot automatically identify and compensate for these deviations in subsequent cutting cycles. As the operating time increases, these minute absolute errors accumulate, eventually causing the cutting length to exceed the tolerance range. Traditional methods typically require periodic shutdowns for mechanical zero-point calibration or manual correction, which not only increases downtime but also raises the labor intensity and maintenance costs for operators. Therefore, a high-precision flying shear cutting device for offset printing plates based on online length adjustment is proposed. Summary of the Invention

[0004] This invention addresses the issue of online precise adjustment of the cutting length of a flying shear, eliminating the problem of accumulated deviations during long-term operation.

The adjusting frame, together with the transmission shaft, is used for auxiliary conveying of the plate material. Each conveyor platform is equipped with a rotating shaft, and a telescopic shaft is installed at the top of the rotating shaft. A docking cylinder is installed at one end of the telescopic shaft. An auxiliary correction mechanism consisting of a connecting block and a set of limit baffles is installed at the bottom output end of the docking cylinder. This mechanism is used to assist in correction and pushing during the plate material conveying process. A pushing seat is installed at the bottom of the connecting block. The telescopic shaft and the rotating shaft provide real-time feedback on the plate material position and compensate for tool wear. The lifting shaft enables the conveyor belt to self-clean. Rubber rollers, in conjunction with pressure sensors, detect flatness at multiple points. The transmission shaft presses to prevent tilting. The pushing and linkage grinding shaft cleans the edges. The coordinated action of these mechanisms can improve the cutting accuracy, production consistency, and transport reliability of offset printing plates.

[0009] A further preferred embodiment of the present invention is as follows: a buffer shaft is installed at the bottom of the limiting baffle, and a rubber sleeve is fitted on the outside of the buffer shaft. The buffer shaft is used to abut against the edge of the cut plate and rotates in conjunction with the rotating shaft and the rotary shaft.

The rotating shaft and the rotary shaft feed synchronously, and the length and angle of the telescopic shaft provide feedback on the moving distance. After the cutting length is reached, the processor sends a signal and can modify the compensation value according to the wear of the tool to ensure consistent quality.

[0010] A further preferred embodiment of the present invention is as follows: a telescopic rod is inserted at the rear end of the telescopic shaft, and a push shaft is provided at the bottom of the telescopic rod. The push shaft swings with the rotation of the telescopic shaft. The push shaft at the bottom of the telescopic rod at the rear end of the telescopic shaft swings with the rotation of the telescopic shaft and presses against the reset shaft to keep the buffer plate and rubber roller at different positions on the top of the plate, thereby realizing multi-point detection of the plate flatness.

[0011] A further preferred embodiment of the present invention is as follows: the transmission shaft is installed on the outside of the docking plate, and a plurality of reset shafts are movably inserted inside the transmission shaft. A buffer pressure plate is connected to the bottom of the reset shaft. The buffer pressure plate is elastic and has a connecting groove at the bottom. A rubber roller is rotatably arranged inside the connecting groove. The rubber roller abuts against the top of the plate. Multiple reset shafts are inserted inside the transmission shaft, and the bottom is connected to the elastic buffer pressure plate. The rubber roller is rotatably arranged in the connecting groove to abut against the top of the plate. This, together with the push seat, reduces the tilting of the plate due to gravity during transportation and avoids bumps during transport.

During the swinging of the push shaft, the reset shaft is driven to move, and the rubber roller can press against different positions of the plate material to detect the flatness of the plate material at multiple contact points. During operation, the rubber roller, together with the buffer plate, presses the plate material to prevent it from tilting under gravity during the transfer process, which would affect the operation of the plate material. The pressure sensor inside the rubber roller can detect the flatness of the plate material at multiple points, and at the same time press the plate material to prevent tilting. Defective products are screened out based on the feedback pressure value.

[0013] A further preferred embodiment of the present invention is as follows: a buffer end block is installed at the top of the push seat, and the buffer end block is located at the bottom of the connecting card block. A transmission wheel is rotatably arranged inside the push seat. A transmission ring and a rotating rod are arranged inside the transmission wheel. The rotating rod is rotatably arranged inside the push seat. The transmission ring is widest at a certain point or section of the circumference and then gradually narrows towards both sides. The transmission wheel is used to abut against the top of the plate. After cutting, the push seat abuts against the cut-off point of the plate and, in conjunction with the rotation of the rotating shaft, pushes the plate to the bottom of the transmission shaft and transports it to the external equipment.

[0014] A further preferred embodiment of the present invention is as follows: a set of pins is provided at the rear end of the pusher seat, and a connecting plate is connected to the pins.

The transmission rod abuts between the transmission ring and the hollow plate. A plurality of piston grooves corresponding to the hollow plate are provided inside the connecting plate, and piston rods are inserted into the piston grooves. A fixing frame is provided at the bottom of the piston rod. A plurality of grinding shafts are provided inside the fixing frame. The rear end of the pusher seat is connected to the hollow plate through the connecting plate. The transmission rod abuts between the transmission ring and the hollow plate. When the transmission wheel rotates, it drives the transmission rod to squeeze the hollow plate, causing the piston rod to move longitudinally, driving the grinding shafts in the fixing frame to reciprocate to clean the debris on the edge of the plate, and then guiding the debris to a recycling mechanism on the conveyor belt for processing.

[0015] Compared with the prior art, the advantages of the present invention are as follows: 1. The present invention uses an auxiliary correction mechanism consisting of a docking cylinder, a connecting block, and a limiting baffle. With the rotation of the telescopic shaft and the rotating shaft, it can provide real-time feedback on the material movement distance and automatically compensate for the cutting length according to the wear of the cutting tool, thus ensuring the consistency of cutting accuracy and production quality.

[0016] 2. The conveyor frame of this invention is equipped with a lifting shaft and a transmission end block, which can periodically stretch and lift the middle part of the conveyor belt upwards to effectively shake off debris and impurities, and avoid foreign objects from affecting the stability of subsequent conveying. At the same time, the reciprocating motion of the grinding shaft cleans the debris on the edge of the plate material, and together with the recycling mechanism, achieves clean production.

[0017] 3. This invention utilizes the swinging motion of the push shaft to drive the reset shaft and rubber rollers, applying pressure at different positions on the printing plate. The built-in pressure sensor collects pressure values ​​at multiple points, detects the flatness of the printing plate in real time, automatically removes defective products, and improves the yield rate.

[0018] 4. This invention uses a reset shaft on the transmission shaft in conjunction with an elastic buffer plate and rubber rollers to continuously press the top of the plate after it is cut, effectively preventing downward tilting or deviation caused by gravity during the transfer process and avoiding collision damage with external conveying equipment.

[0019] 5. In this invention, the transmission wheel inside the pusher seat drives the transmission rod and piston rod to reciprocate through the eccentric transmission ring, thereby driving the grinding shaft to clean the cut edge of the plate. At the same time, the transmission wheel abuts against the top of the plate to achieve stable pushing, smoothly transferring the cut plate to the next process. Attached Figure Description

[0024] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0025] This embodiment mainly describes the title of the high-precision flying shear cutting device for offset printing plates based on online length adjustment. Please refer to [link / reference]. Figures 1-11 Specifically, it is as follows: a high-precision flying shear cutting device for offset printing plates based on online length adjustment, including a connecting seat 1; The connecting seat 1 is equipped with a cutting seat 11 inside. A conveyor frame 2 is installed on one side of the connecting seat 1. An adjusting frame 3 is installed on the top of the conveyor frame 2. A transmission shaft 4 is installed at the outer end of the conveyor frame 2. A set of conveyor tables 31 is installed on the adjusting frame 3. The adjusting frame 3 and the transmission shaft 4 are used to assist in the conveying of the plate material. Each conveyor table 31 is equipped with a rotating shaft, and a telescopic shaft 32 is installed at the top of the rotating shaft. A docking cylinder 33 is set at one end of the telescopic shaft 32. An auxiliary correction mechanism consisting of a connecting block 35 and a set of limit baffles 36 is set at the bottom output end of the docking cylinder 33. This mechanism is used to assist in correction and pushing during the plate material conveying process. A pushing seat 5 is installed at the bottom of the connecting block 35. The plate material position is fed back in real time through the telescopic shaft 32 and the rotating shaft 34, and the tool wear is compensated. The lifting shaft 23 realizes the self-cleaning of the conveyor belt 21. The rubber roller 43 works with the pressure sensor to detect the flatness at multiple points. The transmission shaft 4 presses to prevent tilting. The pushing and 5 linkage grinding shaft cleans the edges. The coordinated action of each mechanism can improve the cutting accuracy of offset printing plates, production consistency and transfer reliability.

[0026] like Figure 2 and Figure 3 As shown, both ends of the conveyor frame 2 are connected to docking plates 22. The adjusting frame 3 is set on the top of the docking plate 22. The connecting seat 1 is movably equipped with a transmission shaft. The conveyor frame 2 is movably equipped with a drive roller 25. The drive roller 25 can drive the conveyor belt 21 to move. The drive roller 25 and the transmission shaft are movably equipped with the conveyor belt 21. During the operation of the equipment, the cut plate material can be transported along the conveyor belt 21 to the external conveying equipment.

[0027] like Figure 2 and Figure 3 As shown, a rectangular frame is connected to the rear end of the conveyor frame 2, and the rectangular frame is fixed to the outer end of the connecting seat 1. A lifting shaft 23 is provided inside the conveyor frame 2, and transmission end blocks 24 are provided at both ends of the lifting shaft 23. The transmission end blocks 24 are movably arranged inside the rectangular frame. The lifting shaft 23 is used to stretch the inside of the conveyor belt 21 and to change the angle of the conveyor belt 21, which can shake off debris and other debris. During the operation of the equipment, the lifting shaft 23 can be moved periodically by means of the transmission end blocks 24, which can stretch and lift the middle part of the conveyor belt 21 upward, which can quickly shake off excess debris and other debris during the conveying process, and can ensure the stability of subsequent conveying.

[0028] like Figure 6 As shown, the top of the adjusting frame 3 is provided with a set of sliding grooves, and the conveying table 31 is movably disposed inside the sliding grooves. The bottom of the docking cylinder 33 is provided with an output shaft, and the bottom of the output shaft is connected to a rotating shaft 34. The connecting block 35 is installed at the bottom of the rotating shaft 34, and the limiting baffle 36 is movably disposed at both ends of the connecting block 35. During the operation of the equipment, the fixing cylinder can drive the connecting block 35 at the bottom to move, and can press the limiting baffle 36 at both ends against one side of the plate material for auxiliary support during the cutting process to ensure cutting accuracy.

[0029] like Figure 6 and Figure 8As shown, a buffer shaft 361 is installed at the bottom of the limiting baffle 36. A rubber sleeve is fitted around the buffer shaft 361. The buffer shaft 361 is used to abut against the edge of the cut plate. It works in conjunction with the rotating shaft and the rotating shaft 34. The length and angle of the telescopic shaft 32 provide feedback on the moving distance of the plate, which facilitates the subsequent cutting of the plate by the equipment. During the plate feeding process, the buffer shaft 361 can abut against the edge of the plate, reducing the possibility of accidental damage to the edge of the plate caused by continuous contact during operation. During operation, as the plate is fed, the rotating shaft 34 and the rotating shaft can maintain a synchronous feeding speed with the plate. The length and angle of the telescopic shaft 32 provide feedback on the moving distance of the plate, and it can continuously abut against the edge of the plate during operation. After reaching the confirmed cutting length, the internal processor sends a signal to cut the plate. The compensation value can be modified according to the wear of the cutting tool to ensure the consistency of production quality.

[0030] like Figure 7 and Figure 8 As shown, a telescopic rod 37 is inserted at the rear end of the telescopic shaft 32, and a push shaft 371 is provided at the bottom of the telescopic rod 37. The push shaft 371 swings as the telescopic shaft 32 rotates. During the rotation of the shaft, the push shaft 371 at the rear end can press against the reset shaft 41, which can keep the buffer plate 42 and the rubber roller 43 at the bottom of the reset shaft 41 at different positions on the top of the plate. Multiple positions can be detected to measure the flatness of the plate.

[0031] like Figure 3 and Figure 4 As shown, the transmission shaft 4 is installed on the outside of the docking plate 22. Several reset shafts 41 are movably inserted inside the transmission shaft 4. The bottom of the reset shaft 41 is connected to a buffer plate 42. The buffer plate 42 is elastic and has a connecting groove at the bottom. A rubber roller 43 is rotatably installed inside the connecting groove. The rubber roller 43 abuts against the top of the plate. During the conveying process, the rubber roller 43 can abut against the top of the plate with the cooperation of the buffer plate 42. After the plate is cut, it can be abutted against one side with the help of the pusher seat 5 and move on the conveyor belt 21. With the cooperation of the transmission shaft 4, it can abut against the top of the plate, reducing the downward displacement and tilting of the plate under the action of gravity during the transportation of the plate, and avoiding accidental bumps when transferred to external conveying equipment as much as possible.

[0032] like Figure 4As shown, the rubber roller 43 has several fixed grooves inside, and pressure sensors are installed in the fixed grooves for auxiliary detection during the conveying process. During the swing of the push shaft 371, the reset shaft 41 is driven to move, and the rubber roller 43 can press against different positions of the plate to detect the flatness of the plate at multiple contact points. During operation, the rubber roller 43, together with the buffer plate 42, presses the plate to prevent the plate from tilting under gravity during the transfer process, which would affect the operation of the plate. During the conveying process, the rubber roller 43 can press against the surface of the plate, and the flatness of the plate can be detected by the pressure value fed back by the contact points, and defective products can be screened out.

[0033] like Figure 9 and Figure 10 As shown, a buffer end block is installed at the top of the push seat 5, and the buffer end block is located at the bottom of the connecting block 35. A transmission wheel 51 is rotatably installed inside the push seat 5. A transmission ring 511 and a rotating rod 512 are installed inside the transmission wheel 51. The rotating rod 512 is rotatably installed inside the push seat 5. The transmission ring 511 is widest at a certain point or section of the circumference and then gradually narrows to both sides. The transmission wheel 51 is used to abut against the top of the plate. After the cutting is completed, as the plate moves on the conveyor belt 21, the push seat 5 can abut against the cut point of the plate and move the plate to the bottom of the transmission shaft 4. During the conveying process, with the help of the transmission wheel 51 abutting against the top of the plate, the plate can be pushed and transported to the external conveying equipment as the rotating shaft and the rotating shaft 34 rotate and cooperate.

[0034] like Figure 9 and Figure 10 As shown, a set of pins is provided at the rear end of the push seat 5, and a connecting plate 53 is connected to the pins. A hollow plate 531 is provided at the upper end of the connecting plate 53. A transmission rod 52 is movably inserted into the push seat 5. The transmission rod 52 abuts between the transmission ring 511 and the hollow plate 531. Several piston grooves corresponding to the hollow plate 531 are provided inside the connecting plate 53, and piston rods 532 are inserted into the piston grooves. A fixing frame 54 is provided at the bottom of the piston rod 532, and several grinding shafts 55 are provided inside the fixing frame 54. During the movement of the pusher seat 5, as the transmission wheel 51 rotates, it can interact with the transmission ring 511 and the transmission rod 52 to squeeze the hollow plate 531, thereby driving the piston rod 532 at the bottom to move longitudinally. When the grinding shaft 55 cleans up the debris on the edge of the plate, the reciprocating grinding shaft 55 guides the debris to the conveyor belt 21. A corresponding recycling mechanism can be set between the conveyor belt 21 and the external conveying equipment to recycle and process the debris generated during the production process.

[0035] During operation, the printing plate is assisted by the adjusting frame 3 at the top of the conveyor frame 2 and the conveyor table 31 on it, in conjunction with the transmission shaft 4. At the same time, the docking cylinder 33 drives the auxiliary correction mechanism consisting of the connecting block 35 and a set of limit baffles 36 to correct and push the printing plate. The length and movement angle of the telescopic shaft 32 provide feedback on the moving distance of the printing plate. After reaching the set cutting length, the cutting seat 11 performs the cutting. The cut printing plate is transported by the drive roller 25 and the conveyor belt 21. The pusher seat 5 abuts against the cut point of the printing plate. The internal transmission wheel 51, in conjunction with the transmission ring 511 and the transmission rod 52, drives the grinding shaft 55 to reciprocate to clean edge debris. The bottom buffer plate 42 of the reset shaft 41 on the transmission shaft 4, in conjunction with the rubber roller 43, presses the top of the printing plate. The pressure sensor inside the rubber roller 43 detects the flatness of the printing plate at multiple points and screens out defective products. During the conveying process, the lifting shaft 23 is driven by the transmission end blocks 24 at both ends to periodically lift the conveyor belt 21 to shake off debris and ensure the stability of subsequent conveying.
