Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting machine production, and in particular to a large-format steel coil laser cutting machine. Background Art

[0002] A large-format steel coil laser cutting machine is a high-precision device specifically used for cutting metal materials such as steel coils. Its working principle is to use a high-power density laser beam to irradiate the workpiece, causing the material to quickly melt, vaporize, ablate or reach the ignition point. At the same time, the molten material is blown away by a high-speed air flow to cut the workpiece. This process requires a high-precision control system to ensure the accurate movement of the laser beam and the cutting quality, and is widely used in fields such as automobile manufacturing, machinery manufacturing, electronics industry, petrochemical industry, and aerospace.

[0003] When a laser cutting machine performs laser cutting, the steel coil is unrolled and laid on the cutting table for cutting. After cutting, continuous conveying is carried out. Most of the current cutting tables usually design some tooth-shaped structures. The main function of these tooth-shaped structures is to fix the processed material and prevent it from sliding during the cutting process, so as to ensure the cutting accuracy and stability. Most of the current tooth-shaped structures are round teeth, fish-scale teeth or square teeth. However, when in use, since the position of the teeth in the table is fixed, after long-term use, the molten workpiece sometimes adheres to the teeth, resulting in unevenness when supporting the workpiece, affecting subsequent cutting processing. And because the cutting is continuous cutting, when cleaning, it is necessary to stop the machine, which affects the cutting efficiency and is not convenient to use. Summary of the Invention

[0004] To overcome the technical defects existing in the prior art, the present invention provides a large-format steel coil laser cutting machine, which has the effect of facilitating the up-and-down switching of the support position during cutting, and cleaning the teeth after switching to avoid affecting subsequent operations, without the need for shutdown cleaning and maintenance, and improving the cutting efficiency.

[0005] The technical solution adopted by the present invention is as follows: A large-format steel coil laser cutting machine includes a frame assembly. The frame assembly includes a support frame, and one end of the support frame is rotatably installed with conveying rollers in an array. The other end inside the support frame is fixedly installed with support assemblies in an array. The support assembly is composed of a fixing mechanism, a cutting support mechanism, a driving mechanism, and a conveying support mechanism. The cutting support mechanism is rotatably installed on the fixing mechanism, and the driving mechanism is fixedly installed at the lower end of the fixing mechanism. The conveying support mechanism is slidably clamped on one side of the fixing mechanism, and the driving mechanism is linked with the conveying support mechanism. When in use, a plurality of the support assemblies are installed in the support frame in an array. The conveying rollers convey the unfolded large-format steel coil onto the plurality of support assemblies. When cutting, the conveying support mechanism is in a descending state, and the unfolded steel coil is laid flat above the cutting support mechanism for cutting processing. After the processing is completed, the driving mechanism raises the conveying support mechanism to convey the steel coil. During conveying, by turning the cutting support mechanism up and down, it is convenient to switch the contact points between the cutting support mechanism and the steel coil, avoiding the molten residues adhering to the cutting support mechanism due to laser cutting during long-term use. After the cutting support mechanism is turned over, when cutting again, the conveying support mechanism descends, and the lower end of the turned-over cutting support mechanism is cleaned through the driving mechanism.

[0006] Preferably, a conveying motor is fixedly installed on one side of the support frame, and the output end of the conveying motor is fixedly connected to one of the conveying rollers. The conveying rollers are linked with each other. Grooves are opened on both sides inside the support frame, and threaded holes are opened in the grooves in an array. Both ends of the fixing mechanism in the support assembly are installed on the threaded holes inside the grooves through external bolts, which is convenient for installing the support assembly and for maintenance. And through the conveying motor, it is convenient to drive one of the conveying rollers, so that each conveying roller rotates in the same direction, facilitating the unfolding and conveying of the steel coil for laser cutting.

[0007] Preferably, longitudinal electric sliding rails are fixedly installed on both sides of the upper end of the support frame above the support assemblies. A gantry is fixedly installed between the movable ends of the longitudinal electric sliding rails. A transverse electric sliding rail is fixedly installed at the lower end inside the gantry. A laser cutter is fixedly installed at the movable end of the transverse electric sliding rail. The longitudinal position of the gantry is adjusted through the longitudinal electric sliding rail, and the transverse position of the laser cutter is adjusted through the transverse electric sliding rail, which is convenient for cutting processing.

[0008] Preferably, the fixing mechanism includes a fixing plate. On both sides of the lower end of the fixing plate, guide plates with a T-shaped structure are fixedly installed. The guide plates are inserted into the driving mechanism. At both ends of the fixing plate, connecting rods with an L-shaped structure are fixedly installed. On one side of the connecting rod, a fixing ear is fixedly installed. The fixing plate is installed on the support frame through the fixing ear. At the end of the connecting rod, a slideway is vertically fixedly installed, and both ends of the conveying support mechanism are vertically and slidably clamped on the slideway. On the opposite sides of the two connecting rods, connecting gears are rotatably installed. On both sides of the connecting gear, they are respectively engaged with the driving mechanism and the conveying support mechanism. When in use, through the fixing ear, the fixing plate is fixed inside the groove on the support frame. Through the guide plate, when the driving mechanism is driven, the driving mechanism moves up and down along the guide plate to improve the stability during movement. And through the slideway, it guides the conveying support mechanism during lifting and lowering. Through the connecting gear, when the driving mechanism rises, the connecting gear rotates, thereby driving the conveying support mechanism to descend. When the driving mechanism descends, the connecting gear rotates in the reverse direction, causing the conveying support mechanism to rise, facilitating the collaborative linkage between the driving mechanism and the conveying support mechanism.

[0009] Preferably, a notch with a serrated structure is formed at the upper end of the fixing plate, and a sleeve is fixedly installed at the upper end of the fixing plate. The cutting support mechanism is rotatably installed on the sleeve. A sector plate is fixedly installed obliquely at the upper end of the connecting rod at one end. A driving motor is fixedly installed on one side of the sector plate, and the output end of the driving motor extends to the other side of the sector plate. A driving gear is fixedly installed at the output end of the driving motor. The driving gear meshes with the driving mechanism. A ratchet gear is fixedly installed between the driving gear and the sector plate at the output end of the driving motor. A gear ring is fixedly installed on the outside of the ratchet gear. The outside of the gear ring meshes with the cutting support mechanism. Through the notch and the sleeve, it is convenient to rotatably install the cutting support mechanism. Through the driving motor, when the driving motor rotates forward, the gear ring drives the cutting support mechanism, so that the diamond-shaped piece rotates with the shaft rod. The driving mechanism is in the lower position, and the linkage gear in the driving mechanism is disengaged from the driving gear. When the driving motor rotates reversely, due to the ratchet gear, the driving motor only drives the driving gear and does not drive the gear ring, so that the cutting support mechanism remains stable. When the driving motor rotates reversely, the driving mechanism is in the upper position, and the linkage gear in the driving mechanism meshes with the driving gear. Then, when the driving gear rotates, the linkage gear rotates to drive the wire brush roller, which is convenient for cleaning the pointed part at the lower end of the diamond-shaped piece.

[0010] Preferably, the cutting support mechanism includes a shaft rod. The shaft rod is rotatably installed on the sleeve. Diamond-shaped pieces are fixedly installed on the shaft rod in an array. The diamond-shaped pieces are located at the position of the notch. Limiting gears and rotating gears are respectively fixedly installed at both ends of the shaft rod. The rotating gear meshes with the gear ring. The rotating gear in the cutting support mechanism always remains meshed with the gear ring. Then, when the driving motor drives the driving gear to rotate forward, the gear ring drives the rotating gear, so that the shaft rod rotates on the sleeve, achieving the effect of reversing the diamond-shaped piece. The diamond-shaped piece reverses inside the notch, which is convenient for swapping the upper and lower positions and facilitating cleaning. When the driving motor rotates reversely, due to the ratchet gear, the gear ring does not apply a driving force to the rotating gear. When the driving motor rotates reversely, the driving mechanism is in the upper position, and the annular teeth in the driving mechanism mesh with the limiting gear, so that the shaft rod remains stable, avoiding the rotation phenomenon of the diamond-shaped piece and improving the stability during cutting support.

[0011] Preferably, the driving mechanism includes a lifting frame. An electric telescopic rod is fixedly installed at the middle position of the lower end of the lifting frame. The telescopic end of the electric telescopic rod is fixedly connected to the fixed plate. Guide holes are formed on both sides of the lifting frame, and the guide plates are inserted into the guide holes. Both ends of the lifting frame are of U-shaped structure, and wire brush rollers are symmetrically and rotatably installed at both ends of the lifting frame. The wire brush rollers are located on both sides of the fixed plate. Through the electric telescopic rod, it is convenient to adjust the distance between the lifting frame and the fixed plate, so that the lifting frame can be lifted and lowered. When lifting and lowering, the lifting frame is lifted and lowered along the guide plate through the guide holes, improving the stability of the lifting frame during lifting and lowering. And through the wire brush rollers, the opposite sides of the wire brush rollers are in contact with both sides of the lower end of the diamond-shaped piece. Thus, when the wire brush rollers rotate, it is convenient to clean the lower end of the diamond-shaped piece.

[0012] Preferably, a linkage gear is fixedly installed at the end of the wire brush roller, and the two wire brush rollers are meshed through the linkage gear. An L-shaped toothed plate is fixedly installed on one side of the lifting frame, and one side of the toothed plate is meshed with the connecting gear. Through the linkage gear, the wire brush rollers rotate in opposite directions, which is convenient for cleaning the diamond-shaped piece. And the wire brush rollers and the linkage gear are lifted and lowered with the lifting frame. When the lifting frame is in the lower position, it avoids the wire brush rollers affecting the flipping of the diamond-shaped piece. When the lifting frame is in the upper position, the linkage gear is meshed with the driving gear in the fixing mechanism, which is convenient for the driving motor to drive the wire brush rollers. And through the toothed plate, when the lifting frame drives the toothed plate to rise, the connecting gear rotates in the reverse direction, so that the conveying and supporting mechanism descends along the slideway. When the lifting frame drives the toothed plate to descend, the connecting gear rotates in the forward direction, and then the conveying and supporting mechanism rises along the slideway. It is convenient to make the driving mechanism and the conveying and supporting mechanism move in opposite directions up and down. When the driving mechanism descends, the conveying and supporting mechanism supports the steel, and the cutting and supporting mechanism flips on the fixed plate.

[0013] Preferably, a V-shaped frame is fixedly installed at one end of the lifting frame far from the linkage gear, and an annular tooth is fixedly installed at the upper end of the V-shaped frame. The annular tooth is meshed with the limiting gear. Through the V-shaped frame and the annular tooth, it is convenient to limit the limiting gear, so that when the driving mechanism is in the upper position, it limits the cutting and supporting mechanism, improving the stability of the diamond-shaped piece when cutting and supporting the steel.

[0014] Preferably, the conveying and supporting mechanism includes supporting rollers. At both ends of each supporting roller, L-shaped connecting rods are rotatably installed. Vertical chutes are formed on both sides of each connecting rod. The connecting rod is slidably clamped inside the slideway through the chutes. Tooth teeth are vertically arranged in an array on one side of the connecting rod. The tooth teeth are meshed with the connecting gear. When the connecting gear rotates forward, the tooth teeth are driven, so that the connecting rod rises along the slideway through the chutes. When the connecting gear rotates reversely, the connecting rod descends along the slideway through the chutes, so that the supporting roller rises and falls. When the supporting roller is in the upper position, the upper surface of the supporting roller is higher than the uppermost end of the diamond-shaped piece, which is convenient for supporting and conveying steel.

[0015] The beneficial effects of the present invention are as follows: 1. By adopting a rotatable cutting and supporting mechanism with an integrated dynamic cleaning function, when conveying after cutting is completed, the cutting and supporting mechanism completes a 180° attitude flip to clean the residues adhered to the tip, effectively eliminating the problem of operation interruption during traditional shutdown cleaning.

[0016] 2. Through the lifting conveying and supporting mechanism, it is convenient to switch between the cutting and conveying states and is applicable to different working conditions.

[0017] 3. By adopting a driving mechanism, when lifting the wire brush roller, the supporting roller moves in the opposite direction, with good synchronization and stable coordination.

[0018] 4. By using a ratchet gear, with a single driving motor, two-way torque output is realized to flip the diamond-shaped piece and drive the wire brush roller. The linkage control is compact in structure, convenient for coordinated driving, and convenient for cleaning the adhered residues. Description of the Drawings

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] As Figures 1 - 11As shown in the figure, this embodiment provides a large-format steel coil laser cutting machine, which includes a frame assembly 1. The frame assembly 1 includes a support frame 101, and a conveying roller 102 is rotatably installed at one end of the support frame 101 in an array. At the other end inside the support frame 101, a support assembly 2 is fixedly installed in an array. The support assembly 2 is composed of a fixing mechanism 21, a cutting support mechanism 22, a driving mechanism 23, and a conveying support mechanism 24. The cutting support mechanism 22 is rotatably installed on the fixing mechanism 21, and the driving mechanism 23 is fixedly installed at the lower end of the fixing mechanism 21. The conveying support mechanism 24 is slidably clamped on one side of the fixing mechanism 21, and the driving mechanism 23 is linked with the conveying support mechanism 24. When in use, a plurality of support assemblies 2 are installed in the support frame 101 in an array. The conveying roller 102 conveys the unfolded large-format steel coil onto the plurality of support assemblies 2. When cutting, the conveying support mechanism 24 is in a descending state, and the unfolded steel coil is laid flat above the cutting support mechanism 22 for cutting processing. After the processing is completed, the driving mechanism 23 is used to raise the conveying support mechanism 24 to convey the steel coil. During the conveying, by turning the cutting support mechanism 22 up and down, it is convenient to switch the contact points between the cutting support mechanism 22 and the steel coil, avoiding the molten residues adhering to the cutting support mechanism 22 due to laser cutting during long-term use. After the cutting support mechanism 22 is turned over, when cutting again, the conveying support mechanism 24 descends, and the lower end of the turned-over cutting support mechanism 22 is cleaned through the driving mechanism 23 without stopping for cleaning, improving the continuity of cutting.

[0033] As a technical optimization solution of the present invention, specifically as Figure 2As shown in the figure, a conveying motor 103 is fixedly installed on one side of the support frame 101, and the output end of the conveying motor 103 is fixedly connected to a conveying roller 102. The conveying rollers 102 are linked together. Grooves 104 are opened on both inner sides of the support frame 101, and threaded holes 105 are arranged in an array inside the grooves 104. Both ends of the fixing mechanism 21 in the support assembly 2 are installed on the threaded holes 105 inside the grooves 104 through external bolts. Through the grooves 104 and the threaded holes 105, it is convenient to install the support assembly 2, and it is convenient to replace each support assembly 2 during long-term use, which is convenient for maintenance. Moreover, through the conveying motor 103, it is convenient to drive one conveying roller 102, and the conveying rollers 102 are linked together, so that each conveying roller 102 rotates in the same direction, which is convenient for unrolling and conveying the steel coil and facilitating the conveyance to the cutting position for laser cutting. Longitudinal electric slide rails 106 are fixedly installed on both sides of the support assembly 2 at the upper end of the support frame 101. A gantry 107 is fixedly installed between the movable ends of the longitudinal electric slide rails 106. A transverse electric slide rail 108 is fixedly installed at the lower end inside the gantry 107. A laser cutter 109 is fixedly installed at the movable end of the transverse electric slide rail 108. The longitudinal position of the gantry 107 is adjusted by the longitudinal electric slide rail 106, and the transverse position of the laser cutter 109 is adjusted by the transverse electric slide rail 108. Furthermore, it is convenient to flexibly adjust the cutting point in the X-axis and Y-axis directions, which is convenient for cutting the unrolled steel coil and facilitating the cutting process.

[0034] As a technical optimization scheme of the present invention, specifically as Figure 7 and Figure 8As shown in the figure, the fixing mechanism 21 includes a fixing plate 2101. On both sides of the lower end of the fixing plate 2101, T-shaped guide plates 2102 are fixedly installed. The guide plates 2102 are inserted on the driving mechanism 23. At both ends of the fixing plate 2101, L-shaped connecting rods 2103 are fixedly installed. On one side of the connecting rod 2103, a fixing ear 2104 is fixedly installed. The fixing plate 2101 is installed on the support frame 101 through the fixing ear 2104. At the end of the connecting rod 2103, a slideway 2105 is vertically fixedly installed, and both ends of the conveying and supporting mechanism 24 are vertically slidably clamped on the slideway 2105. On the opposite sides of the two connecting rods 2103, connecting gears 2106 are rotatably installed. On both sides of the connecting gear 2106, they are respectively meshed with the driving mechanism 23 and the conveying and supporting mechanism 24. When in use, through the fixing ear 2104, the fixing plate 2101 is fixed inside the groove 104 on the support frame 101 and fixed by an external bolt. After fixing, through the guide plate 2102, when the driving mechanism 23 is driven, the driving mechanism 23 moves up and down along the guide plate 2102 to improve the stability during movement. And through the slideway 2105, when the conveying and supporting mechanism 24 is lifted or lowered, the conveying and supporting mechanism 24 moves vertically up and down along the slideway 2105. And through the connecting gear 2106, when the driving mechanism 23 rises, the connecting gear 2106 rotates, and then drives the conveying and supporting mechanism 24 to descend. When the driving mechanism 23 descends, the connecting gear 2106 rotates in the reverse direction, causing the conveying and supporting mechanism 24 to rise, which is convenient for the cooperation and linkage between the driving mechanism 23 and the conveying and supporting mechanism 24, and is convenient for switching between the cutting support and the conveying support states of the laid steel. On the upper end of the fixing plate 2101, a notch 2107 with a serrated structure is opened, and a sleeve 2108 is fixedly installed on the upper end of the fixing plate 2101. The cutting support mechanism 22 is rotatably installed on the sleeve 2108. On the upper end of one end of the connecting rod 2103, a sector plate 2109 is obliquely fixedly installed. On one side of the sector plate 2109, a driving motor 2110 is fixedly installed, and the output end of the driving motor 2110 extends to the other side of the sector plate 2109. The output end of the driving motor 2110 is fixedly installed with a driving gear 2111. The driving gear 2111 is meshed with the driving mechanism 23. Between the output end of the driving motor 2110 and the driving gear 2111, a ratchet gear 2112 is fixedly installed on the sector plate 2109. On the outside of the ratchet gear 2112, a gear ring 2113 is fixedly installed. The outside of the gear ring 2113 is meshed with the cutting support mechanism 22. Through the notch 2107 and the sleeve 2108, it is convenient to rotatably install the cutting support mechanism 22 and convenient for the diamond-shaped piece 2202 in the cutting support mechanism 22 to flip up and down inside the notch 2107. And through the driving motor 2110, when the driving motor 2110 rotates forward, the driving motor 2110 simultaneously drives the driving gear 2111 and the gear ring 2113.The gear ring 2113 drives the cutting support mechanism 22, causing the diamond-shaped piece 2202 to rotate along the shaft rod 2201. When the driving motor 2110 rotates forward, the driving mechanism 23 is in the lower position, and the linkage gear 2305 in the driving mechanism 23 disengages from the driving gear 2111. When the driving motor 2110 rotates in reverse, due to the ratchet gear 2112, the driving motor 2110 only drives the driving gear 2111 and does not drive the gear ring 2113, keeping the cutting support mechanism 22 stable. When the driving motor 2110 rotates in reverse, the driving mechanism 23 is in the upper position, and the linkage gear 2305 in the driving mechanism 23 meshes with the driving gear 2111. Then, when the driving gear 2111 rotates, the linkage gear 2305 rotates to drive the wire brush roller 2304, facilitating the cleaning of the pointed part at the lower end of the diamond-shaped piece 2202.

[0035] As a technical optimization scheme of the present invention, specifically as Figure 9 shown, the cutting support mechanism 22 includes a shaft rod 2201 rotatably installed on a sleeve 2108. Diamond-shaped pieces 2202 are fixedly installed on the shaft rod 2201 in an array. The diamond-shaped pieces 2202 are located at the position of the notch 2107. Limiting gears 2203 and rotating gears 2204 are respectively fixedly installed at both ends of the shaft rod 2201. The rotating gear 2204 meshes with the gear ring 2113. The rotating gear 2204 in the cutting support mechanism 22 always remains meshed with the gear ring 2113. Then, when the driving motor 2110 drives the driving gear 2111 to rotate forward, the gear ring 2113 drives the rotating gear 2204, causing the shaft rod 2201 to rotate on the sleeve 2108, achieving the effect of reversing the diamond-shaped piece 2202. The diamond-shaped piece 2202 reverses inside the notch 2107, facilitating the up and down position swapping and convenient cleaning of the adhered cutting slag. When the driving motor 2110 rotates in reverse, due to the ratchet gear 2112, the gear ring 2113 does not apply a driving force to the rotating gear 2204. When the driving motor 2110 rotates in reverse, the driving mechanism 23 is in the upper position, and the annular teeth 2308 in the driving mechanism 23 mesh with the limiting gear 2203, keeping the shaft rod 2201 stable, avoiding the rotation of the diamond-shaped piece 2202, improving the stability during cutting support, and enhancing the cutting effect.

[0036] As a technical optimization scheme of the present invention, specifically as Figure 10As shown in the figure, the driving mechanism 23 includes a lifting frame 2301. An electric telescopic rod 2302 is fixedly installed at the middle position of the lower end of the lifting frame 2301. The telescopic end of the electric telescopic rod 2302 is fixedly connected to the fixing plate 2101. Guide holes 2303 are formed on both sides of the lifting frame 2301. The guide plate 2102 is inserted into the interior of the guide holes 2303. The two ends of the lifting frame 2301 are of U-shaped structure, and wire brush rollers 2304 are symmetrically and rotatably installed at the two ends of the lifting frame 2301. The wire brush rollers 2304 are located on both sides of the fixing plate 2101. Through the electric telescopic rod 2302, it is convenient to adjust the distance between the lifting frame 2301 and the fixing plate 2101, so that the lifting frame 2301 can be lifted and lowered. When lifting and lowering, the lifting frame 2301 is lifted and lowered along the guide plate 2102 through the guide holes 2303, improving the stability of the lifting frame 2301 during lifting and lowering. And through the wire brush rollers 2304, the opposite sides of the wire brush rollers 2304 are in contact with the two sides of the lower end of the diamond-shaped piece 2202. Then when the wire brush rollers 2304 rotate, it is convenient to clean the lower end of the diamond-shaped piece 2202 and clean the adhered cutting slag, avoiding the influence of the adhered residue during cutting on subsequent use. A linkage gear 2305 is fixedly installed at the end of the wire brush roller 2304, and the two wire brush rollers 2304 are meshed with each other through the linkage gear 2305. An L-shaped toothed plate 2306 is fixedly installed on one side of the lifting frame 2301, and one side of the toothed plate 2306 is meshed with the connecting gear 2106. Through the linkage gear 2305, the wire brush rollers 2304 rotate in opposite directions, which is convenient to clean the diamond-shaped piece 2202, and the wire brush rollers 2304 and the linkage gear 2305 are lifted and lowered along with the lifting frame 2301. When the lifting frame 2301 is in the lower position, it avoids the wire brush rollers 2304 affecting the flipping of the diamond-shaped piece 2202. When the lifting frame 2301 is in the upper position, the linkage gear 2305 is meshed with the driving gear 2111 in the fixing mechanism 21, which is convenient for the driving motor 2110 to drive the wire brush rollers 2304. And through the toothed plate 2306, when the lifting frame 2301 drives the toothed plate 2306 to rise, the connecting gear 2106 rotates reversely, so that the conveying and supporting mechanism 24 descends along the slideway 2105. When the lifting frame 2301 drives the toothed plate 2306 to descend, the connecting gear 2106 rotates forward, and then the conveying and supporting mechanism 24 rises along the slideway 2105, facilitating the driving mechanism 23 and the conveying and supporting mechanism 24 to move in opposite directions up and down. When the driving mechanism 23 descends, the conveying and supporting mechanism 24 supports the steel, and the cutting and supporting mechanism 22 flips on the fixing plate 2101, with a strong linkage effect. A V-shaped frame 2307 is fixedly installed at one end of the lifting frame 2301 far from the linkage gear 2305, and an annular tooth 2308 is fixedly installed at the upper end of the V-shaped frame 2307. The annular tooth 2308 is meshed with the limit gear 2203. Through the V-shaped frame 2307 and the annular tooth 2308, it is convenient to limit the limit gear 2203.Moreover, the V-shaped frame 2307 has an inverted V-shaped structure. When the driving mechanism 23 is in the upper position, it limits the cutting support mechanism 22, improving the stability of the diamond-shaped piece 2202 when supporting the cutting of steel. When the driving mechanism 23 is in the lower position, the annular tooth 2308 is disengaged from the limit gear 2203, facilitating the rotation of the cutting support mechanism 22.

[0037] As a technical optimization scheme of the present invention, specifically as Figure 11 shown, the conveying support mechanism 24 includes a support roller 2401. At both ends of the support roller 2401, L-shaped connecting rods 2402 are rotatably installed. On both sides of the connecting rod 2402, vertical sliding grooves 2403 are provided. The connecting rod 2402 is slidably clamped inside the slideway 2105 through the sliding grooves 2403. On one side of the connecting rod 2402, teeth 2404 are arranged in a vertical array. The teeth 2404 are meshed with the connecting gear 2106. When the connecting gear 2106 rotates forward, it drives the teeth 2404, causing the connecting rod 2402 to rise along the slideway 2105 through the sliding grooves 2403. When the connecting gear 2106 rotates reversely, the connecting rod 2402 descends along the slideway 2105 through the sliding grooves 2403, causing the support roller 2401 to rise and fall. When the support roller 2401 is in the upper position, the upper surface of the support roller 2401 is higher than the uppermost end of the diamond-shaped piece 2202, facilitating the support and conveying of steel. Moreover, through the slideway 2105 and the sliding grooves 2403, the stability during the lifting and lowering of the connecting rod 2402 is improved.
