Description

Technical Field

[0001] This utility model belongs to the field of slitting machine technology, specifically a conveyor belt type horizontal and vertical slitting machine. Background Technology

[0002] A horizontal and vertical slitting machine is an industrial processing equipment mainly used for the precise slitting of roll or sheet materials horizontally (perpendicular to the material's direction of movement) and vertically (along the material's direction of movement). Its core function is to cut wide materials into narrow products of different widths or lengths according to production needs. It is widely used in the precision cutting of packaging materials (such as EPE pearl cotton, bubble wrap), polymer films, composite materials, and other fields. In existing technology, the structural design and working mode of traditional horizontal and vertical slitting machines have the following significant defects: Existing equipment generally uses metal guide rollers symmetrically arranged at the inlet and outlet ends to hold the material, and the material is conveyed through the line contact friction between the guide rollers and the material. However, because the contact between the guide roller and the material is linear, the contact area is insufficient. When the material thickness or density fluctuates, the frictional force is unevenly distributed, leading to fluctuations in the conveying rate and directly causing errors in the slitting size. At the same time, there is no synchronous conveying mechanism below the vertical cutting blade. The material is in a partially suspended state at the moment of cutting. Affected by the cutting resistance, the material is prone to lateral displacement or wave deformation, resulting in a decrease in the flatness of the cut surface. Moreover, the guide roller at the feeding end continuously pushes the material, while the guide roller at the discharge end pulls it in the opposite direction to maintain the material tension. This bidirectional force forms a stress concentration area near the cutting point of the vertical cutting blade, causing local tensile deformation of the material. This phenomenon is particularly significant in elastic materials (such as EPE pearl cotton and elastic film), further amplifying the error in the slitting size. Utility Model Content

[0003] To address the problems mentioned above, this utility model provides a conveyor belt type horizontal and vertical slitting machine. By setting multiple conveyor belt components spanning the vertical cutting mechanism on the frame, a surface contact conveying plane is formed, allowing the material to be smoothly input on the conveying plane while being cut vertically. This solves the dimensional error problems caused by small contact area and unbalanced cutting force in the guide roller feeding mode of traditional slitting machines.

[0008] The conveyor belt pressure plate assembly includes a pressure plate component and a pressure plate drive component that drives the pressure plate component to move up and down. Under the drive of the pressure plate drive component, the pressure plate component presses the conveyor belt support onto the first linear guide rail.

[0009] Furthermore, the conveyor belt assembly includes a conveyor belt and a conveyor belt drive assembly. The conveyor belt drive assembly is connected to a drive shaft. One end of each of the multiple conveyor belts is fitted onto the drive shaft, and the other end is fitted onto a driven shaft.

[0010] Furthermore, the conveyor belt assembly also includes a conveyor belt frame located inside the conveyor belt. The conveyor belt support includes a first support base and a second support base. The first support base is disposed on the conveyor belt frame at one end near the drive shaft, and the bottom end of the first support base is provided with a first slider adapted to the first linear guide rail. The second support base is disposed on the conveyor belt frame at one end near the driven shaft, and the bottom of the second support base is provided with a second slider adapted to the first linear guide rail.

[0011] Furthermore, the conveyor belt assembly also includes a tensioning block fixed to the side of the conveyor belt skeleton and a support plate fitted on the driven shaft. The tensioning block is close to the driven shaft and is provided with a threaded bolt. The bolt's screw end spirals through the tensioning block and abuts against the support plate.

[0012] Furthermore, the vertical cutting mechanism also includes a vertical cutting drive assembly and a vertical blade mounting shaft. The vertical blade mounting shaft is horizontally mounted on the frame, and the vertical cutting drive assembly is connected to the vertical blade mounting shaft for transmission. Multiple vertical cutting circular blades are spaced and sleeved on the vertical blade mounting shaft.

[0013] Furthermore, the discharge mechanism includes a discharge pressure roller and a discharge lower roller arranged vertically.

A third slider corresponding to the vertical cutting circular knife is slidably provided on the second linear guide rail. A vertical knife limiting block is provided on the third slider. A vertical cutting circular knife limiting groove is provided on the vertical cutting circular knife. The edge of the vertical cutting circular knife is rotatably set in the vertical cutting circular knife limiting groove, and the inner wall of the vertical cutting circular knife limiting groove is clearance-fitted with the outer edge of the vertical cutting circular knife.

[0014] Furthermore, the vertical cutting mechanism also includes vertical blade lifting assemblies disposed on both sides of the vertical blade mounting shaft.

[0016] Furthermore, it also includes a pressure roller mechanism, which includes a pressure roller lifting assembly mounted on the frame. The lifting end of the pressure roller lifting assembly is equipped with a pressure roller, which is located above the conveyor belt assembly.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1) The conveyor belt type horizontal and vertical slitting machine of this utility model forms a continuous planar conveying structure by setting multiple conveyor belt components horizontally at intervals on the mounting bracket. Compared with the line contact conveying between the feeding guide roller and the material in the prior art, the surface contact conveying significantly increases the contact area between the material and the conveyor belt, effectively reducing the uneven distribution of friction and the fluctuation of conveying speed caused by the difference in material density or thickness, ensuring uniform material conveying, thereby improving the slitting size accuracy; at the same time, the vertical cutting circular knife is set between the front end and the rear end of the conveyor belt component, and the lower edge of the vertical cutting circular knife extends into the conveying gap, so that while the material is cut vertically, the material is still continuously conveyed synchronously, realizing the dynamic coordination of cutting and conveying, avoiding the material pulling deformation caused by the cutting resistance in the traditional slitting machine, and reducing the error between the material size after cutting and the preset size.

[0019] (2) The conveyor belt type horizontal and vertical slitting machine of this utility model realizes the horizontal position adjustment of the conveyor belt assembly by sliding the conveyor belt bracket on the first linear guide rail. The operator can quickly adjust the conveying gap between the conveyor belt assemblies according to the position of the vertical cutting round blade. When the material is slitting, the lower edge of the vertical cutting round blade is always located within the conveying gap, so that the material below the vertical cutting round blade is in a supported state, ensuring that the material is kept under balanced force when vertically cutting, and improving the flatness of the cutting surface. At the same time, the conveyor belt bracket is pressed and fixed on the first linear guide rail by the conveyor belt pressure plate assembly. The rigid locking and fixing of the conveyor belt pressure plate assembly prevents the conveyor belt assembly from being displaced due to vibration or load during the slitting process. The structure is simple and has good stability. Attached Figure Description

Detailed Implementation

[0031] 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 embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] The following is in conjunction with the appendix Figure 1 To be continued Figure 9 The present invention will be described in detail with reference to specific embodiments.

[0033] This utility model provides a conveyor belt type horizontal and vertical slitting machine, including a frame 1 and a feeding mechanism 2, a vertical cutting mechanism 3, a horizontal cutting mechanism 4, and a discharging mechanism 5 disposed on the frame 1. The horizontal cutting mechanism 4 is located between the feeding mechanism 2 and the discharging mechanism 5, and the vertical cutting mechanism 3 is located above the feeding mechanism 2 and close to the horizontal cutting mechanism 4, wherein:

[0034] The feeding mechanism 2 includes multiple conveyor belt assemblies 21 that are arranged laterally at intervals and conveyed forward synchronously. A conveying gap 22 is formed between adjacent conveyor belt assemblies 21. The front end of the conveyor belt assembly 21 is located at the feeding end of the frame 1, and the rear end of the conveyor belt assembly 21 extends to the feeding end of the cross-cutting mechanism 4.

[0035] The vertical cutting mechanism 3 includes a plurality of vertical cutting circular blades 31 that are arranged laterally at intervals and rotate synchronously. The vertical cutting circular blades 31 are located between the front end and the rear end of the conveyor belt assembly 21, and the lower edge of the vertical cutting circular blades 31 extends into the conveying gap 22.

[0036] In this invention, the feed end of the frame 1 is provided with a feed platform 7, and one side of the discharge end is provided with a discharge platform 8. The feed platform 7, the discharge platform 8 and the upper surface of the conveyor belt assembly 21 are located on the same horizontal plane. Two elongated slots 71 are symmetrically provided on the feed platform 7. The elongated slots 71 extend in the transverse direction. Each elongated slot 71 is slidably connected with a limit component 72, and a feed channel is formed between the two limit components 72. To ensure that the vertical cutting circular blade 31 can be compatible with materials of various thicknesses without affecting the cutting effect, the lower edge of the vertical cutting circular blade 31 is embedded downward into the conveyor gap 22 relative to the upper surface of the conveyor belt assembly 21 by a distance of 1mm-3mm. When cutting materials, the operator first adjusts the gap between the two limiting components 72 according to the width of the material, and then adjusts the spacing between the vertical cutting blades 3 and the conveying gap 22 of the adjacent conveyor belt assembly 21 according to the predetermined cutting width of the material. After ensuring that the lower edge of each vertical cutting blade 31 is within the conveying gap 22 of the adjacent conveyor belt assembly 21, the horizontal and vertical cutting operation of the material can be started. This invention forms a continuous planar conveying structure by arranging multiple synchronously forward-carrying conveyor belt assemblies 21 at horizontal intervals. Compared with the line contact conveying between the feeding guide roller and the material in the prior art, the surface contact conveying significantly increases the contact area between the material and the conveyor belt assembly 21, effectively reducing the uneven distribution of friction and the fluctuation of conveying speed caused by differences in material density or thickness, ensuring uniform material conveying, and thus improving the slitting size accuracy. At the same time, the vertical cutting circular blade 31 is set between the front and rear ends of the conveyor belt assembly 21, and the lower edge of the vertical cutting circular blade 31 extends into the conveying gap 22, so that the material can still be continuously and synchronously conveyed forward during vertical cutting, realizing dynamic coordination between cutting and conveying, avoiding the material pulling deformation caused by the cutting resistance of the vertical cutting circular blade 31 in traditional slitting machines, and reducing the cutting error of material size.

[0037] For details, please refer to Figures 6-9 In some embodiments, the frame 1 is provided with a horizontally extending mounting bracket 11, and the mounting bracket 11 is provided with a first linear guide rail 12. The feeding mechanism 2 also includes a conveyor belt pressure plate assembly 23 and a conveyor belt bracket 24. The conveyor belt bracket 24 is provided in a one-to-one correspondence with the conveyor belt assembly 21, and multiple conveyor belt assemblies 21 are slidably mounted on the first linear guide rail 12 through their corresponding conveyor belt brackets 24.

[0038] The conveyor belt pressure plate assembly 23 includes a pressure plate 230 and a pressure plate drive 231 that drives the pressure plate 230 to move up and down. Under the drive of the pressure plate drive 231, the pressure plate 230 presses the conveyor belt bracket 24 onto the first linear guide rail 12. In this embodiment, by sliding the conveyor belt bracket 24 onto the first linear guide rail 12, the conveying gap 22 between the conveyor belt assemblies 21 can be adjusted. The operator can quickly adjust the conveying gap 22 between the conveyor belt assemblies 21 according to the position of the vertical cutting circular blade 31. When cutting materials, the lower edge of the vertical cutting circular blade 31 is always located within the conveying gap 22, so that the material below the vertical cutting circular blade 31 is in a supported state, ensuring that the material is kept under balanced force when cutting vertically and improving the flatness of the cut surface. At the same time, the conveyor belt pressure plate assembly 23 presses and fixes the conveyor belt bracket 24 onto the first linear guide rail 12. The rigid locking and fixing of the conveyor belt pressure plate assembly prevents the conveyor belt assembly 21 from shifting due to vibration or load during the cutting process. The structure is simple and has good stability.

[0039] For details, please refer to Figures 6-9 In some embodiments, the pressure plate drive component 231 includes a cylinder bracket 2310 and a plurality of second cylinders 2311 fixedly mounted on the cylinder bracket 2310. The cylinder bracket 2310 is fixedly connected to the mounting bracket 11. The cylinder bracket 2310 is provided with a plurality of through holes, and the piston rods of the plurality of second cylinders 2311 pass through the through holes and are fixedly connected to the pressure plate component 230. The operator controls the extension and retraction of the piston rods of the second cylinders 2311, thereby controlling the pressure plate component 230 to press or release the conveyor belt bracket 24, thereby fixing or releasing the position of the conveyor belt assembly 21. Of course, in other embodiments, other lifting structures can also be used, which are not limited here, as long as they can drive the pressure plate component 230 to move downward to press the conveyor belt bracket 24, thereby fixing the position of the conveyor belt assembly 21.

[0040] For details, please refer to Figures 6-9In some embodiments, the conveyor belt assembly 21 includes a conveyor belt 210 and a conveyor belt drive assembly 211. The conveyor belt drive assembly 211 includes a first motor 2110 and a first reducer 2111. The output end of the first reducer 2111 is connected to the drive shaft 212. One end of each of the multiple conveyor belts 210 is sleeved on the drive shaft 212, and the other end is sleeved on the driven shaft 213. The drive shaft 212 is driven to rotate by the conveyor belt drive assembly 211, thereby driving the multiple conveyor belts 210 to rotate synchronously, achieving smooth forward conveying of materials. In this application, in order to achieve synchronous rotation of the conveyor belts 210, the drive shaft 212 is a long shaft extending laterally. All conveyor belts 210 are sleeved on the same drive shaft 212, while the driven shaft 213 is not limited. Each conveyor belt 210 can correspond to a short driven shaft 213, or multiple conveyor belts 210 can be sleeved on a long driven shaft 213.

[0041] For details, please refer to the diagram. Figures 6-9 In some embodiments, the conveyor belt assembly 21 further includes a conveyor belt frame 214 located inside the conveyor belt 210. The conveyor belt support 24 includes a first support 240 and a second support 241. The first support 240 is disposed on the conveyor belt frame 214 near the drive shaft 212, and the bottom end of the first support 240 is provided with a first slider 242 adapted to the first linear guide rail 12. The second support 241 is disposed on the conveyor belt frame 214 near the driven shaft 213, and the bottom of the second support 241 is provided with a second slider 243 adapted to the first linear guide rail 12. Through the dual-point sliding design of the first support 240 and the second support 241, the levelness of the conveyor belt assembly 21 during the adjustment process is ensured, avoiding deviation caused by the tilt of the conveyor belt 210 during material conveying, which would affect the cutting accuracy.

[0042] For details, please refer to Figure 9 In some embodiments, the pressure plate member 230 includes a horizontal pressure plate 2300 and a vertical pressure plate 2301 fixedly connected to one end of the horizontal pressure plate 2300. The horizontal pressure plate 2300 presses down on the first support seat 240 and the second support seat 241 under the drive of the pressure plate driving member 231.

[0043] For details, please refer to Figures 6-7In some embodiments, the conveyor belt assembly 21 further includes a tension block 215 fixed to the side of the conveyor belt frame 214 and a support plate 216 fitted onto the driven shaft 213. The tension block 21 is close to the driven shaft 213, and the tension block 215 is provided with a threaded bolt 217. The screw end of the bolt 217 spirals through the tension block 215 and abuts against the support plate 216. Preferably, there are two tension blocks 215, symmetrically installed on both sides of the conveyor belt frame 214. In this embodiment, each conveyor belt 210 corresponds to a short driven shaft 213, and the driven shaft 213 is movably connected to the conveyor belt frame 214 through the support plate 216. In this embodiment, by screwing in or out the bolts 217 on both sides, the support plate 216 is moved longitudinally (i.e., moved back and forth along the conveyor belt frame 214), thereby realizing the longitudinal movement of the driven shaft 213. This changes the distance between the driven shaft 213 and the drive shaft 212, thus adjusting the tension of the conveyor belt 210 and ensuring that the conveyor belt 210 is always in a moderately tensioned state to avoid slippage or overload. Since the force on the conveyor belt 210 varies during repeated operation, resulting in different tension levels, the tension of each conveyor belt 210 is adjusted individually in this application, achieving flexibility in adjustment.

[0044] For details, please refer to Figure 6 and Figure 8 In some embodiments, the drive shaft 212 is a hexagonal shaft, which is connected to the conveyor belt 210 via a rolling shaft 218. The rolling shaft 218 has a hexagonal through hole that matches the shape of the hexagonal shaft. The hexagonal shaft and the inner hole of the rolling shaft 218 can directly mesh with each other through shape matching, without the need to adjust the circumferential angle, ensuring accurate positioning and simple installation. At the same time, the hexagonal symmetrical structure of the drive shaft 212 ensures that the shear stress generated by the torque is evenly distributed on six planes, reducing local stress concentration and extending the service life of the drive shaft 212. Moreover, the hexagonal meshing structure can effectively suppress the vibration of the drive shaft 212 during high-speed operation, reducing material cutting errors caused by vibration.

[0045] For details, please refer to Figures 1-4 In some embodiments, the vertical cutting mechanism 3 further includes a vertical cutting drive assembly 32 and a vertical blade mounting shaft 33. The vertical blade mounting shaft 33 is horizontally mounted on the frame 1. The vertical cutting drive assembly 32 is drive-connected to the vertical blade mounting shaft 33. Multiple vertical cutting circular blades 31 are spaced apart and sleeved on the vertical blade mounting shaft 33, and their positions are fixed by detachably mounted circular blade holders 35. The vertical cutting drive assembly 32 includes a third motor and a third reducer. The output end of the third reducer is drive-connected to the vertical blade mounting shaft 33, thereby realizing synchronous rotation and cutting of multiple vertical cutting circular blades 31.

[0046] For details, please refer to Figures 2-5In some embodiments, the discharge mechanism 5 includes a discharge pressure roller 51 and a discharge lower roller 52 arranged vertically. Discharge pressure roller 51 has discharge pressure roller lifting assemblies 53 at both ends, and a second linear guide rail 57 is laterally connected between the discharge pressure roller lifting assemblies 53. The second linear guide rail 57 is located on one side of the feeding end of the cross-cutting mechanism 4. A third slider 58 corresponding to the vertical cutting circular blade 31 is slidably mounted on the second linear guide rail 57. A vertical blade limiting block 59 is mounted on the third slider 58, and a vertical cutting circular blade limiting groove 590 is mounted on the vertical cutting circular blade. The edge of the vertical cutting circular blade 31 is rotatably positioned within the vertical cutting circular blade limiting groove 590, and the inner wall of the vertical cutting circular blade limiting groove 590 is clearance-fitted with the outer edge of the vertical cutting circular blade 31. In this embodiment, the vertical blade limiting block 59 is cuboid in shape and vertically mounted on the third slider 58. The gap between the outer edge of the vertical cutting circular blade 31 and the inner wall of the vertical cutting circular blade limiting groove 590 is 0.1mm-0.5mm. By setting a vertical cutting circular blade limiting groove 590 on the vertical blade limiting block 59 and making the vertical blade limiting block 59 slidably connected to the second linear guide rail 57 through the third slider 58, the radial runout of the vertical cutting circular blade 31 caused by high-speed rotation or cutting resistance can be limited, and the blade wear caused by hard contact friction between the vertical cutting circular blade 31 and the vertical cutting circular blade limiting groove 590 can be avoided.

[0047] For details, please refer to Figure 1 , Figures 4-5 In some embodiments, the vertical cutting mechanism 3 further includes vertical blade lifting components 34 disposed on both sides of the vertical blade mounting shaft 33. The vertical blade lifting components 34 include a first cylinder 340 fixedly connected to the frame 1. The telescopic end of the first cylinder 340 is provided with a positioning bearing seat 341, and the positioning bearing seat 341 is provided with a positioning bearing 342. The two ends of the vertical blade mounting shaft 33 are respectively rotatably connected to the positioning bearing 342. When the material cutting width changes, it is necessary to adjust the spacing between the vertical cutting circular blades 31. At this time, the vertical blade mounting shaft 33 can be lifted by the vertical blade lifting components 34 so that the lower edge of the vertical cutting circular blades 31 is adjusted to the upper surface of the conveyor belt 210 for easy adjustment. After the spacing between the vertical cutting circular blades 31 and the conveying gap of the conveyor belt assembly 21 are adjusted, the vertical blade mounting shaft 33 is lowered by the vertical blade lifting components 34 so that the lower edge of the vertical cutting circular blades 31 is once again located within the conveying gap 22, thus completing the adjustment of the height position of the vertical cutting circular blades 31.

[0048] For details, please refer to Figure 2 and Figure 5In some embodiments, the cross-cutting mechanism 4 includes a cross-blade lifting assembly 41 fixedly mounted on the frame 1. A transverse gate 42 is provided on the lifting end of the cross-blade lifting assembly 41. The cross-blade lifting assembly 41 includes a second motor 410, a second reducer 411, and a second drive shaft 412. The output end of the second motor 410 is connected to the second reducer 411 for transmission. The output end of the second reducer 411 is fitted with the second drive shaft 412. Both ends of the second drive shaft 412 are rotatably connected to connecting rod support arms 413. The upper ends of the two connecting rod support arms 413 are rotatably connected to limit posts 414. The limit posts 414 are fixedly connected to both ends of the transverse gate 42. This embodiment of the horizontal and vertical slitting machine also includes a length measuring system (not shown in the figure) for real-time detection of material conveying length and generation of feedback signals. The control system uses the feedback signals and fixed-length parameter information from the length measuring system to control the rotation of the second motor 410, which in turn drives the second drive shaft 412 to rotate, thereby driving the connecting rod support arms 413 at both ends to rotate. The rotation of the connecting rod support arms 413 will cause the limiting post 414 to move up and down, thereby realizing the vertical lifting of the horizontal gate 42 fixedly connected to the limiting post 414, and realizing the fixed-length horizontal cutting of the material. Of course, in other embodiments, other lifting structures can also be selected, as long as they can achieve stable up and down movement of the horizontal gate 42. This is not limited here, and those skilled in the art can design it according to production needs.

[0049] For details, please refer to Figure 1 , Figures 4-5 In some embodiments, a pressure roller mechanism 6 is also included. The pressure roller mechanism 6 includes a pressure roller lifting assembly 61 mounted on the frame 1. A pressure roller 62 is mounted on the lifting end of the pressure roller lifting assembly 61, and the pressure roller 62 is located above the conveyor belt assembly 21. The pressure roller lifting assembly 61 includes a fourth motor 610. The output end of the fourth motor 610 is provided with a first conveyor belt assembly 611. The first conveyor belt assembly 611 is rotatably connected to a first worm gear screw jack 612. The lifting screw of the first worm gear screw jack 612 is fixedly connected to the pressure roller 62. The rotational motion of the first conveyor belt assembly 611 is converted into the linear motion of the lifting screw of the first worm gear screw jack 612, thereby realizing the vertical height adjustment of the pressure roller 62. The structure of the pressure roller lifting assembly 61 is not limited here, as long as the lifting and adjusting of the pressure roller 62 can be achieved. This embodiment improves the material conveying stability and cutting quality by setting the pressure roller 62.

[0050] For details, please refer to Figure 2 , Figures 4-5In this embodiment, the discharge mechanism 5 also includes a discharge roller drive assembly 54 installed at one end of the discharge lower roller 52. The discharge roller drive assembly 54 includes a fifth motor 540. The output end of the fifth motor 540 is connected to one end of the discharge lower roller 52 via a second conveyor belt assembly 541. The other end of the discharge lower roller 52 is connected to the discharge pressure roller 51 via a third conveyor belt assembly 542, thereby achieving synchronous rotation of the discharge pressure roller 51 and the discharge lower roller 52 to complete the output of the cut material. To ensure that the pressure roller 62 and the discharge pressure roller 51 can be adjusted in height synchronously, a second turbine screw jack 55 is fixedly connected to one end of the discharge pressure roller 51. The second turbine screw jack 55 and the first turbine screw jack 612 are connected via a transmission optical shaft 56, thereby achieving synchronous lifting and lowering adjustment of the pressure roller 62 and the discharge pressure roller 51.

[0051] The working principle of this utility model is as follows: First, adjust the distance between the two limiting components 72 according to the width of the material, and adjust the spacing between the vertical cutting circular blades 31 and the conveying gap 22 between multiple conveyor belt components 21 according to the material cutting requirements to ensure that the lower edge of the vertical cutting circular blade 31 is within the conveying gap 22 of the adjacent conveyor belt components 21. Then, the pressure plate drive component 231 drives the pressure plate component 230 to press down the first support seat 240 and the second support seat 241. Next, the material is placed on the feeding platform 7. The material parameters and cutting length are input in the control system display interface. After the control system adjusts the pressure roller 62 and the discharge pressure roller 51 to press down the material through the pressure roller lifting component 61 and the discharge pressure roller lifting component 53, the conveyor belt drive component 211, the vertical cutting drive component 32, the horizontal blade lifting component 41 and the discharge roller drive component 54 control the material to be conveyed and cut. Finally, the cut material is unloaded through the discharge platform 8 (or automatically unloaded by a robot).
