Description

Technical Field

[0001] This invention relates to the field of roller flying shear technology, specifically to an adjustable gap roller flying shear device. Background Technology

[0002] As an indispensable core cutting equipment in continuous automated production lines for metal coils, thin steel strips, and plastic sheets, the roller flying shear relies on the working principle of high-speed cutting by opposing upper and lower paired roller shearing wheels. It can accurately complete fixed-length segmented high-speed shearing operations while maintaining continuous dynamic conveying of the sheet material without stopping the machine. It is a key supporting equipment for deep processing production lines of cold-rolled steel strip, galvanized steel strip, color-coated coil, plastic film, plastic sheet, aluminum strip, and other coil materials.

[0003] Existing adjustable gap roller flying shear devices are prone to lateral deviation during the uncoiling and conveying of rolled materials due to uneven roll diameter, parallelism deviation of conveying rollers, and tension fluctuations. This results in problems such as width tolerance exceeding limits, material shortage on one side, and increased waste in the cut finished products. Furthermore, the adjustment of the gap between the shearing blade and the shearing groove wheel often uses manual adjustment with a single-sided screw or a split lifting mechanism. Adjustment requires manual disassembly and reassembly of shims and repeated tightening of adjusting bolts. When changing to produce different thicknesses of sheet materials, the downtime for adjustment is long, which significantly reduces the efficiency of continuous production line operation. Moreover, the single-sided adjustment structure is prone to inconsistent lifting heights at both ends of the shearing blade, causing the blade edge and the lower groove wheel to tilt. During the cutting process, quality defects such as incomplete cuts on one side, sheet material extrusion and deformation, burrs on the cut, and beveled edges are likely to occur.

[0004] Based on this, the present invention designs an adjustable gap roller flying shear device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable gap roller flying shear device to solve the problems mentioned in the background art. Existing adjustable gap roller flying shear devices are prone to lateral deviation during the uncoiling and conveying of coiled materials due to uneven coil diameter, parallelism deviation of conveying rollers, and tension fluctuations. This results in problems such as width tolerance exceeding the tolerance, single-sided material shortage, and increased waste in the cut finished products. In addition, when adjusting the gap between the shearing blade and the shearing groove wheel, a single-sided screw manual adjustment or a split lifting mechanism is often used. During adjustment, shims need to be manually disassembled and reassembled, and adjusting bolts are repeatedly turned. When changing to produce different thickness plates, the downtime for adjustment is long, which greatly reduces the continuous operation efficiency of the production line. Moreover, the single-sided adjustment structure is prone to inconsistent lifting height at both ends of the shearing blade, and the blade edge and the lower groove wheel are tilted. During the cutting process, quality defects such as incomplete cutting on one side, plate extrusion deformation, burrs on the cut, and beveled edges are likely to occur.

[0011] As a further embodiment of the present invention, the shearing mechanism includes a mounting plate, and there are two mounting plates. Two mounting side plates are symmetrically fixedly mounted on both sides of the mounting plate, and the two mounting side plates are closely attached to the first mounting plate. Two lifting columns are symmetrically fixedly mounted between the two mounting side plates on the same side of the mounting plate, and one end of the curved top bar away from the lifting top bar is slidably connected to the surface of the second lifting column. A shearing blade wheel is rotatably mounted between the two mounting plates through a bearing. The shearing blade wheel is positioned corresponding to the shearing groove wheel. Two transmission turntables are fixedly mounted through the mounting plates at both ends of the shearing blade wheel. A T-shaped transmission protrusion is fixedly mounted on one edge of the transmission turntable.

[0012] As a further embodiment of the present invention, the guiding and correcting mechanism includes an installation strip, which is fixedly connected to the inner wall of the mounting base between adjacent support rollers and shear groove rollers. The bottom of the installation strip is symmetrically fixedly mounted with installation slide rods, and lifting slide bars are slidably connected through the surfaces of the two installation slide rods. The bottom ends of the two installation slide rods are fixedly connected through the lifting slide bars with limit slide bars. The two ends of the lifting slide bars are respectively fixedly connected with connecting rods, and the end of the connecting rod away from the lifting slide bar is fixedly connected with a pusher slide.

[0013] As a further embodiment of the present invention, the inner wall of the mounting base is provided with transmission gears three on both sides of the transmission gear one via bearings, and the transmission gears three mesh with the transmission gear one.

[0014] As a further embodiment of the present invention, the linkage mechanism includes two limiting slides, which are respectively fixedly connected to the mounting base and the side of the mounting top plate, and the positions of the two limiting slides are corresponding. The two limiting slides are slidably connected to a linkage slide bar through a protrusion, and the top end of the linkage slide bar is slidably connected to an I-shaped drive protrusion, the bottom end of the linkage slide bar is slidably connected to an I-shaped transmission protrusion, and the center position of the linkage slide bar is slidably connected to a T-shaped transmission protrusion. A linkage bar is rotatably connected between the I-shaped transmission protrusion and the I-shaped drive protrusion.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention, by setting up a shearing groove wheel, a shearing blade wheel, a linkage slide bar, a transmission gear one, a transmission gear three, a pusher slide, and a curved correction frame, allows workpieces such as steel strips and plates to be conveyed to the shearing station of the shearing groove wheel and shearing blade wheel inside the mounting base via a conveying device. A dual-output shaft motor is then activated to drive two drive shafts to rotate, causing the drive turntable to rotate continuously. I-shaped drive protrusions fixed to the edge of the drive turntable continuously push and pull the linkage slide bar along the limit slide in a reciprocating linear motion. Simultaneously, the I-shaped drive protrusions and I-shaped transmission protrusions are connected by a linkage bar, enabling the first and second drive turntables to rotate synchronously at the same speed. When the first drive turntable rotates, it directly drives the second transmission gear connected to both ends of the shaft to rotate, thereby driving the first transmission gear at both ends of the shearing groove wheel to rotate. This ensures that the shearing blade wheel and the lower shearing groove wheel rotate in completely opposite directions, with the upper and lower cutting edges facing each other. As the workpiece continues to move until it reaches the contact position between the shearing groove wheel and the shearing blade wheel, the two sets of wheels rotating in opposite directions instantly engage the plate, completing the fixed-length flying shear cutting. The transmission gears at both ends of the shearing groove wheel mesh with the transmission gear three, driving the push column to make a circumferential eccentric motion. The push column is embedded in the internal groove of the push carriage. During the eccentric rotation, the push carriage is continuously pushed and pulled to complete the lifting and reciprocating motion, driving the connecting rod and the lifting slide to slide up and down along the two vertically installed slide rods. The fixed push block in the middle of the connecting rod is embedded in the push strip-shaped groove opened at the bottom of the curved correction frame. When the lifting slide moves up and down, the push block slides along the push strip-shaped groove. Relying on the inclined plane thrust, the curved correction frames arranged symmetrically on both sides swing back and forth around the pin at the end of the mounting strip. The two sets of curved correction frames are respectively arranged on the left and right sides of the plate feeding channel. During the swing, they are attached to and pushed from the side of the plate, automatically correcting the left and right deviation of the plate.

[0017] 2. This invention, by setting up electric push rods, push slide bars, push rotating bars, lifting top bars, curved top bars, and lifting columns, synchronously controls the extension or retraction of electric push rods on both sides of the mounting base according to the thickness requirements of the workpiece to be processed. This directly drives the push slide bar to move linearly along the T-shaped slide bar. The push slide bar pushes the push rotating bar to rotate and swing around the pin. The upper groove of the push rotating bar slides in cooperation with the lifting column. During the swing, the lifting column is continuously pulled or pushed, thereby driving the lifting top bar to slide along the paired fixed seats. When the lifting top bar moves, it pulls the curved top bar to rotate around the connecting fixed column, thus converting the sliding of the lifting top bar into the curved top bar. The vertical lifting and pushing operation at the other end allows the curved top bar to slide and be sleeved on the surface of the second lifting column at the end away from the lifting top bar. When the curved top bar rotates, it lifts the second lifting column, driving the entire shearing mechanism to rise. When the curved top bar rotates downward, the shearing mechanism descends synchronously by its own weight. The second mounting side plates on both sides of the mounting plate slide vertically against the first mounting side plate of the support mechanism. The first mounting side plate acts as a vertical guide and limit for the shearing mechanism, ensuring that there is no left or right deviation during the lifting process. The shearing blade wheel supported between the two mounting plates rises and falls synchronously and smoothly, thereby changing the vertical gap between the shearing blade wheel and the fixed shearing groove wheel below, which facilitates the shearing of workpieces such as steel strips and plates of different thicknesses.

[0032] 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.

[0033] Please see Figures 1-11 The present invention provides a technical solution:

[0034] An adjustable gap roller flying shear device includes a mounting base 1, which serves as the support base for the entire machine. Support rollers 101 are symmetrically mounted on the top of both sides of the inner wall of the mounting base 1 via bearings. A shearing groove wheel 102 is mounted on the inner wall of the mounting base 1 at the center position between the two support rollers 101 via bearings. Transmission gears 103 are fixedly mounted on both ends of the shearing groove wheel 102 on the inner side of the mounting base 1. A connecting shaft 104 is mounted on the inner side of the mounting base 1 at the bottom of the shearing groove wheel 102 via bearings. Transmission gears 105 are fixedly mounted on both ends of the connecting shaft 104 on the inner side of the mounting base 1, and the transmission gears 105 mesh with the transmission gears 103. Transmission turntables 106 are fixedly mounted on both ends of the connecting shaft 104 through the mounting base 1, and I-shaped transmission protrusions 107 are fixedly mounted on one edge of the transmission turntables 106.

[0035] During operation, the two side support rollers 101 passively rotate with the conveying of the plate, lifting the plate and smoothly feeding it into the shearing station, reducing friction and scratches on the bottom surface of the plate, and ensuring horizontal feeding of the plate; the shearing groove wheel 102 is a fixed lower shearing base, with transmission gear 103 integrally connected to both ends, and the connecting shaft 104 is vertically arranged below the shearing groove wheel 102. The two transmission gears 105 at both ends continuously mesh with the transmission gear 103. The transmission turntable 106 extending from the base at both ends of the connecting shaft 104 rotates synchronously and coaxially. The eccentric I-shaped transmission protrusion 107 on the edge of the transmission turntable 106 follows the transmission turntable 106 to perform eccentric circular motion. When the connecting shaft 104 is driven to rotate, the transmission gear 105 synchronously drives the transmission gear 103 to rotate in the opposite direction, and finally drives the shearing groove wheel 102 to rotate at a uniform speed.

[0036] The mounting base 1 is symmetrically equipped with adjustment drive mechanisms 2 on both sides, which provide power for adjusting the shear gap. The adjustment drive mechanism 2 includes an electric push rod 201, which is fixedly connected to the center of the bottom side of the mounting base 1. A push slide 202 is fixedly installed at the telescopic end of the electric push rod 201. T-shaped slides 203 are symmetrically fixedly installed on both sides of the electric push rod 201 on the side of the mounting base 1, and the push slide 202 is slidably connected to the surface of the T-shaped slide 203. Push rotating bars 204 are rotatably installed at both ends of the mounting base 1 on the same side of the electric push rod 201 through pins. The two ends of the push slide 202 are slidably connected to one end of the push rotating bar 204 through protrusions. The two ends of the push rotating bar 204 are respectively provided with through slots, and the protrusions at both ends of the push slide 202 are slidably connected to the slots at the two push rotating bars 204 that are close to each other. When the push slide 202 moves up and down, the protrusions at both ends of the push slide 202 slide in the slots at one end of the push rotating bar 204, pushing the push rotating bar 204 to rotate.

[0037] During operation, the electric push rods 201 on both sides receive control signals and extend / retract synchronously, driving the front pusher slide 202 to move vertically as a whole. The T-shaped slide 203 limits the pusher slide 202 from the upper and lower sides, restricting the pusher slide 202 to move only vertically and eliminating left and right deviation. The protrusions at both ends of the pusher slide 202 are embedded in the end grooves of the pusher rotating bar 204. When the pusher slide 202 moves vertically, it pushes and pulls the pusher rotating bar 204, causing the pusher rotating bar 204 to rotate around the pin.

[0038] Support mechanisms 3 are fixedly installed at the four corners of the top of the mounting base 1. Each support mechanism 3 includes two mounting side plates 301. Connecting posts 302 are symmetrically fixed between the two mounting side plates 301. A curved top strip 303 is rotatably mounted through the surface of each connecting post 302. The two support mechanisms 3 on the same side form a group. The four corner support mechanisms 3 form a rigid frame with the two mounting side plates 301 and the connecting posts 302. The connecting posts 302 provide a fulcrum for the curved top strip 303 to rotate around the connecting posts 302.

[0039] Mounting base 1 has fixed seats 205 fixedly mounted on its top sides and the sides of support mechanism 3, respectively. A lifting top bar 206 is slidably mounted between two opposing fixed seats 205. The lifting top bar 206 is slidably connected to one end of the curved top bar 303 through a protrusion. Protrusions are fixedly connected to both sides of the lifting top bar 206 at corresponding positions to the curved top bar 303. A through groove is symmetrically provided at the end of the curved top bar 303 near the lifting top bar 202. The protrusions on both sides of the lifting top bar 206 are slidably connected to the curved top bar 303. Inside the through groove near one end of the lifting top bar 202; the bottom end of the lifting top bar 206 is provided with a lifting column 207, and the lifting column 207 is slidably connected to the end of the push rotating bar 204 away from the push slide bar 202. The bottom end of the lifting top bar 206 is provided with a through rectangular through groove, and the lifting column 207 is fixedly connected to the center position inside the rectangular through groove. The lifting top bar 206 and the fixed seat 205 are respectively provided with a limiting strip-shaped slide groove 208, and the limiting strip-shaped slide groove 208 is slidably connected to the inner surface of the fixed seat 205.

[0040] During operation, when the rotating bar 204 is pushed to swing, the upper sliding groove drives the lifting column 207 to move up and down synchronously, thereby pulling or pushing the lifting top bar 206 to slide vertically along the paired fixed seats 205. The limiting strip-shaped sliding groove 208 on the lifting top bar 206 is fitted onto the surface of the fixed seat 205 to limit it, ensuring that the lifting top bar 206 will not tilt or deflect when sliding vertically. When the lifting top bar 206 moves vertically, the protrusions on both sides of the lifting top bar 206 drive the curved top bar 303 to rotate around the connecting fixed column 302 in a lever-like manner.

[0041] A shearing mechanism 6 is slidably mounted on the top of the mounting base 1 between the two sets of support mechanisms 3. The shearing mechanism 6 includes two mounting plates 601. Two mounting side plates 602 are symmetrically fixed on both sides of the mounting plate 601, and the two mounting side plates 602 are closely attached to the mounting side plate 301. A lifting column 603 is symmetrically fixed between the two mounting side plates 602 on the same side of the mounting plate 601. A through groove is provided at one end of the curved top strip 303 near the lifting column 603. The through groove is slidably sleeved on the surface of the second lifting column 603, and the end of the curved top bar 303 away from the lifting top bar 206 is slidably connected to the surface of the second lifting column 603; a shearing blade wheel 604 is rotatably mounted between the two mounting plates 601 through a bearing, the shearing blade wheel 604 is positioned corresponding to the shearing groove wheel 102, and the two ends of the shearing blade wheel 604 are respectively fixedly mounted on the second transmission turntable 605 through the mounting plates 601, and a T-shaped transmission protrusion 606 is fixedly mounted on one side edge of the second transmission turntable 605.

[0042] During operation, when the curved top bar 303 rotates, it drives the entire shearing mechanism 6 to move vertically up and down through the lifting column 603. The mounting side plate 602 slides vertically against the mounting side plate 301, and the two side plates form a vertical guide rail, restricting the mounting plate 601 to move only up and down without any left or right deviation. The linkage mechanism 8 drives the transmission turntable 605 to rotate at a constant speed. The transmission turntable 605 drives the middle shearing blade wheel 604 to rotate synchronously. The shearing blade wheel 604 and the lower shearing groove wheel 102 are directly opposite each other, and their rotation directions are opposite. The cutting edges continuously converge towards each other, and the shearing mechanism 6 moves up and down to shear workpieces of different thicknesses.

[0043] A mounting plate 4 is fixedly installed on the top of the four support mechanisms 3. A dual-output shaft motor 5 is fixedly installed on the top of the mounting plate 4. Drive shafts 501 are fixedly connected to the output ends on both sides of the dual-output shaft motor 5. A fixed frame 502 is rotatably installed on the end of the drive shaft 501 away from the dual-output shaft motor 5 through a bearing. The fixed frame 502 is fixedly connected to the top edge of the mounting plate 4. A drive turntable 503 is fixedly installed through the fixed frame 502 on the end of the drive shaft 501 away from the dual-output shaft motor 5. An I-shaped drive protrusion 504 is fixedly installed on the side edge of the drive turntable 503.

[0044] Linkage mechanisms 8 are respectively provided on both sides perpendicular to the mounting base 1 and the adjustment drive mechanism 2. Each linkage mechanism 8 includes two limiting slides 801, which are fixedly connected to the sides of the mounting base 1 and the mounting top plate 4, respectively, and their positions correspond to each other. A linkage slide bar 802 is slidably connected inside the two limiting slides 801 through a protrusion. The top end of the linkage slide bar 802 is slidably connected to the I-shaped drive protrusion 504, and the bottom end of the linkage slide bar 802 is slidably connected to the I-shaped transmission protrusion 107. The central position of the movable slide bar 802 is slidably connected to the T-shaped transmission protrusion 606. The I-shaped transmission protrusion 107 and the I-shaped drive protrusion 504 are rotatably connected by a linkage bar 803. The limiting slide 801 is long and has a T-shaped through groove on its side. The linkage slide bar 802 is slidably connected to the vertical direction of the through groove on the side of the limiting slide 801, and the linkage bar 803 is close to the outside of the limiting slide 801. The linkage slide bar 802 and the linkage bar 803 are connected by a protruding post, and the protruding post is slidably connected to the T-shaped through groove on the side of the limiting slide 801.

[0045] During operation, the dual-output shaft motor 5 on the mounting plate 4 synchronously outputs torque to the left and right sides, driving the two drive shafts 501 to rotate synchronously. The ends of the drive shafts 501 are supported and limited by the bearings of the fixed frame 502 to ensure that the drive shafts 501 rotate at high speed without radial sway. The drive turntable 503 at the end of the drive shaft 501 moves in a uniform circular motion with the drive shaft 501. The I-shaped drive protrusions 504 eccentrically arranged on the edge of the drive turntable 503 synchronously follow the drive turntable 503 to move in an eccentric circular trajectory, continuously outputting reciprocating push and pull power to the linkage mechanism 8. The upper and lower paired limiting slides 801 constrain the linkage slide bar 802 to slide back and forth only in the horizontal direction. The top, middle and bottom of the linkage slide bar 802 are respectively fitted with I-shaped drive protrusion 504, T-shaped transmission protrusion 606 and I-shaped transmission protrusion 107. When the dual-output shaft motor 5 drives the I-shaped drive protrusion 504 to rotate eccentrically, it pushes and pulls the linkage slide bar 802 to move horizontally. The bottom of the linkage slide bar 802 drives the I-shaped transmission protrusion 107 to rotate eccentrically, synchronously constraining the rotation speed of the bottom shear groove wheel 102 and the first transmission turntable 106. The middle of the linkage slide bar 802 constrains the T-shaped transmission protrusion 606, synchronously locking the rotation speed of the upper shear blade wheel 604 and the second transmission turntable 605. At the same time, the linkage bar 803 connects the I-shaped drive protrusion 504 and the I-shaped transmission protrusion 107, further reinforcing the synchronization of the first transmission turntable 106 and the drive turntable 503.

[0046] The mounting base 1 has symmetrical guide and correction mechanisms 7 on both sides inside, which simultaneously limit and correct the feeding sides of the sheet metal to ensure that the workpiece does not deviate during shearing. The guide and correction mechanism 7 includes a mounting strip 701, which is fixedly connected to the inner wall of the mounting base 1 between the adjacent support roller 101 and shearing groove wheel 102. The bottom of the mounting strip 701 is symmetrically fixedly mounted with mounting slide rods 702. The surfaces of the two mounting slide rods 702 are slidably connected with lifting slide bars 703. The bottom ends of the two mounting slide rods 702 are fixedly connected to the lifting slide bars 703 with limit slide bars 704. The two ends of the lifting slide bars 703 are respectively fixedly connected with connecting rods 705. The end of the connecting rod 705 away from the lifting slide bar 703 is fixedly connected to a pusher slide 706.

[0047] On the inner wall of the mounting base 1, on both sides of the transmission gear 103, transmission gears 707 are rotatably mounted via bearings, and the transmission gears 707 mesh with the transmission gear 103. A push post 708 is fixedly mounted on the edge of the transmission gear 707 near the push slide 706, and the push post 708 is slidably connected to the push slide 706. The push slide 706 has a through slot on the side near the transmission gear 103, and the push post 708 slides and engages within the slot on the side of the push slide 706. When the push post 708 rotates with the transmission gear 103, it slides within the slot on the side of the push slide 706, thereby allowing the push slide 706 to move. 6. Up and down movement; Curved correction brackets 709 are symmetrically mounted on both ends of the mounting strip 701 via protrusions. The protrusions at both ends of the mounting strip 701 are circular. The curved correction brackets 709 rotate and are locked on the surface of the protrusions, so that the curved correction brackets 709 rotate around the protrusions. The bottom of the curved correction brackets 709 is symmetrically provided with push strip-shaped grooves 710. A push block 711 is fixedly installed at the center of the surface of the connecting rod 705, and the push block 711 is slidably connected to the inside of the push strip-shaped groove 710. The curved correction brackets 709 are symmetrically provided with push strip-shaped grooves 710 at the bottom of the protrusions that are rotatably connected to the mounting strip 701, and the push strip-shaped grooves 710 are slidably connected to the surface of the push block 711.

[0048] During operation, the vertical mounting slide rod 702 provides a vertical sliding track for the lifting slide bar 703. The limiting slide bar 704 locks the bottom end of the mounting slide rod 702 to prevent the lifting slide bar 703 from sliding downwards. The lifting slide bar 703 can slide up and down along the two mounting slide rods 702 as a whole. When the lifting slide bar 703 moves up and down, it drives the connecting rods 705 at both ends to rise and fall synchronously. The pusher slide 706 at one end of the connecting rod 705 is sleeved on the outside of the pusher column 708. When the eccentric rotation occurs, the push-pull slide 706 moves up and down. When the cylindrical push column 708 moves eccentrically in a circular motion with the transmission gear 707, the push column 708 slides inside the strip-shaped through groove on the side of the push slide 706, thereby applying a vertical up-and-down thrust to the push slide 706. This pushes the push slide 706 to drive the connecting rod 705 and the lifting slide bar 703 to move vertically up and down along the mounting slide bar 702, driving the lifting slide bar 703 to reciprocate up and down. When transmission gear 103 rotates, it meshes and drives transmission gear 3 707 to rotate synchronously. Transmission gear 3 707 drives push column 708 to follow transmission gear 3 707 in a complete circumferential eccentric motion, continuously pushing and pulling push slide 706 to move up and down reciprocally. Push slide 706 drives connecting rod 705 and lifting slide bar 703 to move up and down. Push block 711 in the middle of connecting rod 705 slides along the bottom push strip groove 710 of curved correction frame 709. The inclined surface of push strip groove 710 is subjected to vertical thrust from push block 711, which is converted into horizontal lateral thrust, driving the left and right sets of curved correction frames 709 to swing back and forth inward and outward around the pin at the end of mounting bar 701. The two curved correction frames 709 on both sides synchronously press against the center of the plate. When the plate deviates, the single-sided frame pushes the side of the plate to complete the centering correction.

[0049] Working principle of this invention:

[0050] The sheet material is fed into the shearing station of the shearing groove wheel 102 and the shearing blade wheel 604 by an external conveying device. It first contacts the support rollers 101 symmetrically arranged on both sides of the inner wall of the mounting base 1. The support rollers 101 passively rotate synchronously with the sheet material feed, evenly lifting the sheet material from the bottom to prevent it from drooping or being scratched on the bottom surface, ensuring the sheet material enters the shearing station of the shearing groove wheel 102 and the shearing blade wheel 604 horizontally and straight, completing the pre-feeding conveying. Then, the dual-shaft motor 5 above the mounting top plate 4 is started, synchronously driving two drive shafts 501 to rotate at a uniform speed. The drive turntable 50 at the end of the drive shafts 501... 3. The I-shaped drive protrusion 504, which is eccentrically fixed at the edge of the drive turntable 503, rotates synchronously with the shaft. It follows the drive turntable 503 to make eccentric circular motion, and continuously outputs reciprocating push and pull power to the linkage slide bar 802 of the linkage mechanism 8. It limits the linkage slide bar 802 to only make horizontal reciprocating sliding along the limit slide 801. The top of the linkage slide bar 802 is sleeved with the I-shaped drive protrusion 504, the middle is sleeved with the T-shaped transmission protrusion 606, and the bottom is sleeved with the I-shaped transmission protrusion 107. The eccentrically moving I-shaped drive protrusion 504 continuously pushes and pulls the linkage slide bar 802 horizontally and reciprocates, forcibly constraining the three turntables to operate synchronously.

[0051] The bottom I-shaped transmission protrusion 107 is fixed on the transmission turntable 106. The linkage slide bar 802 drives the transmission turntable 106 to rotate synchronously. The transmission turntable 106 drives the connecting shaft 104 to rotate synchronously, so that the transmission gear 105 at both ends of the connecting shaft 104 meshes with the transmission gear 103 at both ends of the shear groove wheel 102, driving the shear groove wheel 102 to rotate stably and uniformly. The middle part of the linkage slide bar 802 drives the T-shaped transmission protrusion 606 to drive the transmission turntable 605 to rotate synchronously. The shear blade wheel 604 is coaxially mounted on the transmission turntable 605, so that the rotation direction of the shear blade wheel 604 is completely opposite to that of the lower shear groove wheel 102, and the upper and lower blades continuously converge towards each other.

[0052] The transmission gears 103 at both ends of the shearing groove wheel 102 synchronously mesh with the transmission gear 707. The transmission gear 707 rotates synchronously with the transmission gear 103. The push column 708, which is eccentrically fixed at the end face of the transmission gear 707, completes a full eccentric circular motion. The push column 708 is embedded in the internal groove of the push slide 706. During the eccentric rotation, the push slide 706 is continuously pushed and pulled to perform a lifting and reciprocating motion, which drives the two connecting rods 705 to jointly drive the lifting slide bar 703 to slide smoothly up and down along the two vertically mounted slide bars 702. The push block 711, fixed in the middle of the connecting rod 705, is embedded in the push strip groove 710 at the bottom of the curved correction frame 709. When the lifting slide bar 703 moves up and down, the push block 711 slides along the push strip groove 710, converting the vertical thrust into a horizontal lateral thrust through the inclined surface of the groove. This drives the two sets of curved correction frames 709, which are symmetrically arranged on the left and right, to swing back and forth around the pin at the end of the mounting bar 701. Automatic correction is completed before the board enters the shearing station, ensuring that the width of each section of the cut board is uniform and greatly reducing the scrap rate.

[0053] The sheet material, supported by the support roller 101 and aligned by the curved correction frame 709, is continuously conveyed forward. When it reaches the contact position between the shearing groove wheel 102 and the shearing blade wheel 604, the counter-rotating shearing groove wheel 102 and the shearing blade wheel 604 instantly engage the sheet material, achieving dynamic fixed-length flying shearing. For sheets of different thicknesses, the electric push rods 201 on both sides of the mounting base 1 synchronously receive electrical control signals and extend or retract synchronously, pushing the slide bar 202 to move vertically along the T-shaped slide bar 203, thus pushing the slide bar... The protrusions at both ends of the strip 202 slide in cooperation with the sliding groove at the end of the pusher bar 204. Pushing and pulling the pusher bar 204 rotates and swings around the pin. The sliding groove at the end of the pusher bar 204 away from the sliding bar is sleeved on the outside of the lifting column 207. During the swing, the lifting column 207 is pulled / pushed. The lifting column 207 drives the lifting top bar 206 to slide vertically along the paired fixed seats 205. The limiting strip-shaped sliding groove 208 opened on the lifting top bar 206 cooperates with the fixed seat 205 to restrict the lifting top bar 206 to move only vertically and not deflect.

[0054] The lifting top bar 206 is slidably connected to the curved top bar 303. The curved top bar 303 forms a lever structure with the connecting fixed column 302 as the fulcrum, driving the curved top bar 303 to rotate in a lever-like manner. The other end of the curved top bar 303 is sleeved with the second lifting column 603, lifting the second lifting column 603, so that the entire shearing mechanism 6 is raised synchronously, increasing the gap between the shearing blade wheel 604 and the shearing groove wheel 102. When the curved top bar 303 rotates downward, the shearing mechanism 6 descends smoothly by its own weight, reducing the shearing gap. The second mounting side plates 602 on both sides of the shearing mechanism 6 slide vertically against the first mounting side plate 301 of the support mechanism 3, forming a two-way vertical guide. There is no left or right tilt during the entire lifting process, ensuring that the shearing blade wheel 604 is always parallel to the shearing groove wheel 102, and there will be no problem of damaging the plate due to the small gap on one side. By adjusting the extension and retraction of the electric push rod 201 by electric control, the shearing gap can be infinitely finely adjusted to adapt to the cutting needs of various workpieces, such as thin and thick materials.
