Description

Technical Field

[0001] This utility model relates to the field of shearing equipment technology, specifically to a steel plate slitting machine that facilitates the replacement of cutting blades. Background Technology

[0002] A steel plate slitting machine is a mechanical device used to cut wide steel plates into multiple narrow steel strips. Its main function is to process large-sized steel plates into steel strips of the required width through precise cutting to meet different production needs. This equipment is widely used in metal processing, automobile manufacturing, home appliance production, construction, and other industries.

[0003] A search revealed Chinese patent publication number CN218016093U, which discloses a slitting device based on a sheet metal slitting machine. The device includes a base, and a rotating shaft support, an n-shaped first slitting blade support, and an n-shaped second slitting blade support, all vertically mounted on the base. The first and second slitting blade supports hold a first and a second slitting blade positioned vertically. The rotating shaft support houses a first rotating shaft and a second rotating shaft. The first rotating shaft is connected to one end of the first slitting blade via a first universal joint, and the second rotating shaft is connected to one end of the second slitting blade via a second universal joint. However, this slitting device has the following problems:

[0004] In the existing technology, the cutter on the slitting machine is prone to wear due to prolonged friction with the steel plate and excessive mechanical stress during the shearing process. Furthermore, factors such as the hardness of the steel plate, surface impurities, and cutting speed also accelerate the wear of the cutter, resulting in a decrease in cutting accuracy and efficiency.

[0005] Based on this, this utility model designs a steel plate slitting machine that facilitates the replacement of cutting blades to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a steel plate slitting machine that is easy to replace the cutting blade.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A steel plate slitting machine with easy-to-change cutting blades includes a worktable, a correction mechanism, a drive mechanism, an installation mechanism, and a cutting roller. The top inner wall of the worktable is fixedly connected to a correction mechanism to prevent the steel plate from shifting during the feeding process. The two sides of the worktable are fixedly connected to a drive mechanism to provide power to the slitting machine. An installation mechanism is provided at one end of the drive mechanism. The two ends of the cutting roller are fixedly connected between the two installation mechanisms.

[0009] The mounting mechanism includes a mounting column, a mounting box, a transmission assembly, and a locking assembly. One end of the mounting column is fixedly connected to the output end of the drive mechanism, and the other end of the mounting column is detachably connected to the mounting box. The two mounting boxes are symmetrically mounted at their adjacent ends on both ends of the cutting roller. The middle of the mounting box is rotatably connected to a transmission assembly for transmitting power, and the outer wall of the mounting box is equipped with a locking assembly for rotating and locking the transmission assembly.

[0010] Furthermore, the transmission assembly includes a gear ring, multiple transmission gears are rotatably connected to the bottom of the mounting box, and multiple rack plates are slidably connected inside the mounting box. The gear ring meshes with the transmission gears, and the rack plates mesh with the transmission gears.

[0011] Furthermore, the locking assembly includes a locking plate and fixing pins. The bottom end of the locking plate is rotatably connected to the outside of the gear ring, and multiple fixing pins are evenly and fixedly connected to the outer wall of the mounting box. The shape of the through groove on the locking plate is adapted to the shape of the fixing pin.

[0012] Furthermore, the other end of the mounting post is cubic in shape, and the inner wall of the mounting box is provided with a groove, the shape of which is adapted to the shape of the other end of the mounting post.

[0013] Furthermore, the drive mechanism includes a mounting base, with two mounting bases mounted on adjacent sides of the bottom of the workbench. A support post is slidably connected to the top of the mounting base, and the support post can be fixed to the mounting base with screws. A motor and a follower column are mounted on one of the support posts, and two follower columns are rotatably mounted at the corresponding positions of the other support post. A transmission device is fixedly connected to the output end of the motor, and the output end of the motor is driven to the corresponding follower column through the transmission device. The other two follower columns are driven to the other two through the transmission device.

[0014] Furthermore, the correction mechanism includes a left-right rotating lead screw slide table. Each of the two output ends of the left-right rotating lead screw slide table is fixedly connected to a sliding plate. Two fixed columns are symmetrically fixedly connected to both ends of the sliding plate. A reset component is fixedly connected to the top of the fixed column. A rotating pile is rotatably connected to the bottom of the fixed column. An L-shaped connecting plate is fixedly connected to the bottom of the rotating pile through a connecting column. The L-shaped connecting plate is right-angled symmetrical. Correction wheels are rotatably connected to both ends of the L-shaped connecting plate.

[0015] Furthermore, the reset assembly includes a torsion spring and a starting post. The upper end of the torsion spring is fixedly connected to the top of the fixed post, and the torsion spring is sleeved on the outer side of the middle part of the fixed post. The bottom of the starting post is fixedly connected to the top of the rotating pile, and the starting post is in contact with the lower end of the torsion spring.

[0016] Furthermore, a rotating ring is fixedly connected to the bottom of the fixed column, and a rotating groove is opened inside the rotating pile, with the shape of the rotating ring matching that of the rotating groove.

[0017] Compared with the prior art, the advantages of this utility model are as follows: 1. The mounting column is fixed by moving the support pile, so that it is initially connected with the mounting box. The rotating gear ring drives the transmission gear and rack plate, so that the rack plate slides into the slot of the mounting column, realizing the connection between the mounting column and the mounting box, thereby transmitting power to drive the cutting roller to rotate. During disassembly, the rack plate can be separated from the mounting column by reversing the operation, and the cutting roller can be taken out, realizing convenient disassembly and assembly of the cutter and improving replacement efficiency;

[0018] 2. After the steel plate is fed via the conveyor belt, the left-right rotating screw slide table drives the sliding plate to move the correction mechanism towards the center, so that the correction wheel contacts both sides of the steel plate. If the steel plate is tilted, the correction wheel on the tilted side is forced to rotate the L-shaped connecting plate, which in turn causes the rotating pile and the fixed column to rotate relative to each other, squeezing the starting column and causing the torsion spring to deform. The restoring force of the torsion spring causes the rotating pile to have a reverse movement tendency, which is transmitted to the correction wheel through the L-shaped connecting plate, pushing the steel plate back to straight and ensuring the subsequent cutting accuracy.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The terms "left," "right," "front," "back," "up," and "down" mentioned in the following description refer to the orientation from the perspective of a three-dimensional view. Example 1

[0031] Please refer to the accompanying drawings in the instruction manual. Figures 1-7 A steel plate slitting machine with easy-to-change cutting blades includes a worktable 1, a correction mechanism 2, a drive mechanism 3, an mounting mechanism 4, and a cutting roller 5. The correction mechanism 2 is fixedly connected to the top inner wall of the worktable 1 to prevent the steel plate from shifting during the feeding process. The drive mechanism 3 is fixedly connected to both sides of the worktable 1 to provide power to the slitting machine. The mounting mechanism 4 is provided at one end of the drive mechanism 3. The two ends of the cutting roller 5 are fixedly connected between the two mounting mechanisms 4.

[0032] The workbench 1 includes a housing, a control console, a conveyor belt, a waste collection bin, and a finished product recycling bin. The housing provides external protection and a mounting base for the entire slitting machine. The control console, installed at the bottom front of the housing, is used to control the operation of the entire slitting machine. The conveyor belt, installed at the bottom front of the housing, is used to feed the steel plate slitting machine. The waste collection bin, installed directly below the cutting roller 5, is used to collect and process waste generated during the slitting process. The finished product recycling bin, installed at the rear rear of the housing, is used to collect and process the cut steel plates.

[0033] The drive mechanism 3 includes a mounting base 301. Two mounting bases 301 are fixedly connected to the bottom sides of the workbench 1 by screws on their adjacent sides. A support post 302 is slidably connected to the top of the mounting base 301, and the support post 302 and the mounting base 301 can be fixed by screws. A motor 303 and a follower column 304 are fixedly connected to one of the support posts 302. Two follower columns 304 are installed at the corresponding positions of the other support post 302. The follower columns 304 can rotate. A transmission device 305 is fixedly connected to the output end of the motor 303. The output end of the motor 303 is connected to the corresponding follower column 304 through the transmission device 305. The other two follower columns 304 are connected through the transmission device 305. The transmission device 305 is a common belt and pulley.

[0034] In this utility model, during installation, the two support piles 302 are moved to the designated position on the mounting base 301 and then fixed with screws. The motor 303 is turned on, and the operation of the motor 303 drives the pulley of the transmission device 305 to rotate. Thus, through the transmission action of the belt and pulley, the subsequent mounting mechanism 4 and the two cutting rollers 5 are driven to rotate synchronously, thereby cutting the steel plate into strips. In this way, a single drive source can drive the two cutting rollers 5 to rotate synchronously, thereby achieving the effect of saving energy.

[0035] The mounting mechanism 4 includes a mounting column 401, which is fixedly connected to the pulley of the transmission device 305. The other end of the mounting column 401 is cubic in shape and is detachably connected to a mounting box 402. The two ends of the cutting roller 5 are respectively fixedly connected to the adjacent ends of the two mounting boxes 402. A gear ring 403 is rotatably connected to the middle of the mounting box 402. Multiple transmission gears 404 are rotatably connected to the bottom of the mounting box 402. Multiple rack plates 405 are slidably connected inside the mounting box 402. The gear ring 403 meshes with the transmission gears 404, and the rack plates 405 mesh with the transmission gears 404. A locking component is installed on the outer wall of the mounting box 402 to lock the gear ring 403.

[0036] The locking assembly includes a locking plate 406 and a fixing pin 407. The bottom end of the locking plate 406 is rotatably connected to the outside of the gear ring 403. Multiple fixing pins 407 are evenly fixedly connected to the outside of the mounting box 402. The shape of the through groove on the locking plate 406 is adapted to the shape of the fixing pin 407.

[0037] In this invention, after the two support piles 302 are moved to a designated position and fixed, the mounting column 401 is driven into the mounting box 402. The rectangular shape of the other end of the mounting column 401 engages with the groove on the inner wall of the mounting box 402 for initial connection. Then, the gear ring 403 is rotated, causing four transmission gears 404 to rotate in the same direction. This rotation of the transmission gears 404 drives four corresponding rack plates 405 to slide towards the center of the mounting box 402 until they enter the slots on the mounting column 401. Thus, the mounting column 401 and the mounting box 402 are connected via the four rack plates 405, and the power of the drive mechanism 3, through the transmission of the mounting column 401, drives the mounting box 402 and the cutting roller 5 to... Rotate the engaging plate 406 to engage it with the fixing pin 407. The engaging plate 406 and the fixing pin 407 are fixed with a stainless steel duckbill buckle structure. This duckbill buckle prevents the gear ring 403 from remaining stationary during the cutting process, thus keeping the transmission gear 404 and the rack plate 405 in a synchronous stationary state. This prevents the rack plate 405 from moving outward due to the centrifugal force generated when the entire cutter roller rotates, which could cause the cutting roller 5 to unlock accidentally. When disassembling the cutter, the engaging plate 406 can be rotated in the opposite direction to unlock it. Then, the gear ring 403 can be rotated in the opposite direction to separate the rack plate 405 from the mounting post 401. After removing the screws at the bottom of the support post 302, the support post 302 can be pulled outward to remove the two cutting rollers 5. This achieves convenient disassembly and assembly of the cutter and improves the efficiency of cutter replacement.

[0038] The correction mechanism 2 includes a left-right rotating lead screw slide 201. Both output ends of the left-right rotating lead screw slide 201 are fixedly connected to a sliding plate 202. Both ends of the sliding plate 202 are fixedly connected to two fixed posts 203. The top of the fixed post 203 is fixedly connected to a torsion spring 204. The torsion spring 204 is sleeved on the outer side of the middle part of the fixed post 203. The bottom of the fixed post 203 is rotatably connected to a rotating post 205. The bottom of the fixed post 203 is fixedly connected to a rotating ring. The rotating post 205 has a rotating groove inside. The shape of the rotating ring matches the shape of the rotating groove. The torsion spring 204 is sleeved between the rotating pile 205 and the sliding plate 202. The top of the rotating pile 205 is fixedly connected to the starting column 206, and the starting column 206 is in contact with the lower end of the torsion spring 204. The bottom of the rotating pile 205 is fixedly connected to the L-shaped connecting plate 207 through the connecting column. The L-shaped connecting plate 207 is in a right-angle symmetrical shape, and both ends of the L-shaped connecting plate 207 are rotatably connected to the correction wheel 208.

[0039] In this invention, a steel plate is placed on the conveyor belt of the workbench 1 for feeding. The left-right rotating screw slide 201 is opened, and its operation drives two sliding plates 202 to move in opposite directions, thereby driving the entire correction mechanism 2 to move towards the center of the conveyor belt. This allows the correction wheels 208 on both sides to contact the sides of the steel plate. When the steel plate tilts, the correction wheel 208 facing the tilt is subjected to force, which drives the L-shaped connecting plate 207 to rotate. This causes the rotating pile 205 to rotate relative to the fixed column 203. Through the squeezing action of the starting column 206, the torsion spring 204 is deformed. The deformation restoring force of the torsion spring 204 causes the entire rotating pile 205 to have a reverse movement tendency, thereby transmitting the reverse rotation to the L-shaped connecting plate 207. This causes the L-shaped connecting plate 207 to rotate, and through the action of the correction wheels 208, the steel plate is kept straight, which facilitates subsequent cutting operations and ensures cutting accuracy.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
