Description

TECHNICAL FIELD

[0001] The utility model relates to material slitting equipment technical field, concretely relates to a slitting machine. BACKGROUND

[0002] The slitting machine, also known as a longitudinal cutting machine or a longitudinal shearing machine, is a device for longitudinally cutting wide roll materials. It can cut wide-width plates, sheets, or films into several strips with a certain width through multiple sets of upper and lower circular knives on the cutting device. It has precise and efficient cutting capacity to meet production needs and is widely used in many material processing industries.

[0003] Currently, the commonly used slitting machines on the market are mainly used for processing flexible materials such as cloth strips, paperboard, glass paper, aluminum foil, and film, as well as for processing hard metal materials such as steel plates, stainless steel plates, and copper plates. However, for brittle special materials containing glass fibers such as epoxy resin plates and semiconductor glass cloth plates commonly used in the generator and motor industries, the processing precision requirement is very high due to their brittle material characteristics. If the above slitting machines are directly used to process brittle special materials, the high-speed rotating cutting tools will usually produce some vibration during cutting, so the material will be affected by the vibration and extrusion of the cutting tool during cutting, resulting in unstable phenomena. It will cause position deviation and deformation, and further produce fracture marks at the cutting edge, until the whole plate material is irregularly broken and scrapped, seriously affecting the processing quality. Therefore, in order to successfully process the above materials, special machine modification is required for the existing slitting machine model in actual application, which is dedicated to processing a certain type of brittle special material. However, the modification is difficult and expensive, and most of the modifications are only for cutting a certain type of brittle special material, which cannot be applied to other brittle special materials, and its versatility is greatly limited.

[0004] In addition, even when the existing slitting machine is used for processing common strip material, the cutting device of the slitting machine needs to be adjusted according to different materials and thicknesses of the strip material, such as adjusting the meshing distance between the upper and lower cutters, changing the processing speed of the cutters, replacing the cutter brand, and the like, so that the cutting force is adapted to the cutting of the corresponding strip material. After the above parameters are determined, the slitting machine can only be used for processing specific materials and thicknesses, otherwise, if it is directly used for processing strip material of a type that is not adapted, the slitting processing quality will be affected, and it will be difficult to meet the requirements. For example, when the existing slitting machine used for processing thick and hard materials is directly used for cutting thin and hard materials or flexible materials, the rigidity of the flexible materials and the thin and hard materials is smaller than that of the thick and hard materials, so when the materials are cut by the cutting device, the materials are also prone to unstable phenomena, such as position deviation, fluctuation or deformation, which in turn causes the cutting edge of the strip material to have jagged edges, burrs, burrs and the like, and it is difficult to form a smooth straight edge, resulting in low processing precision. For some flexible materials, even processing accidents such as segmentation and rupture may occur. The above problems also limit the versatility of the slitting machine in different materials and thicknesses, and the cutting device of the slitting machine needs to be adjusted in advance every time different types of strip material are cut. The size and mass of the cutter shaft and cutter are usually large, making the replacement operation steps complex and inconvenient every time, increasing the workload of workers, affecting production and processing efficiency, and having great limitations in industry applications. Utility model content

[0005] The utility model aims at overcoming the problems in the prior art, and provides a slitting machine that can process strip material of different materials and thicknesses, so as to improve its versatility and processing efficiency.

[0006] The slitting machine comprises a cutting device, the cutting device comprises oppositely arranged upper and lower rollers, and a plurality of cutting cutters for cutting strip material are installed opposite each other between the upper and lower rollers, guide assemblies through which the strip material can pass are horizontally arranged between each group of cutting cutters along the feeding and discharging direction of the cutting strip material, the guide assemblies each comprise upper and lower guide plates opposite each other, a fixed frame is arranged on the feeding side of the cutting device, a strip material feeding port is arranged on the fixed frame, the upper and lower guide plates of each guide assembly are fixedly connected to the upper and lower sides of the strip material feeding port at the feeding end, respectively, an adjustable clamping device is arranged on the discharging side of the cutting device, the discharging end of each guide assembly passes through the clamping device, the clamping distance between the upper and lower guide plates is adjusted by the clamping device, and the distance L between the clamping position of the clamping device on the guide assembly and the cutting position of the cutting device is 150mm-245mm.

[0007] The slitting machine provided by this utility model utilizes a guide assembly to initially guide and limit the strip material entering the cutting device for processing, preventing the strip material from drooping directly on the discharge side of the cutting device. A clamping device is installed on the discharge side of the cutting device to clamp and limit the strip material passing through the guide assembly. The distance L between the clamping point of the clamping device and the cutting point of the cutting device is set to 150mm to 245mm. This distance L can be manually adjusted according to the material type of the strip, enabling the slitting machine to process strip materials of corresponding types. It ensures that the clamping and limiting function of the clamping device effectively prevents the strip material from vibrating due to the vibration and compression of the cutting tool. The upper and lower clamping distance of the clamping device can be adjusted according to the thickness of the strip material to adapt to strip materials of different thicknesses. After the above adjustments, the strip material can pass normally through the guide assembly and be slit by the cutting device. At the same time, it can be sufficiently limited by the clamping device on the discharge side of the cutting device, maintaining the stability of the strip material during the cutting process. For brittle special materials, it can prevent the material from shifting or deforming due to the vibration and compression of the cutting tool during cutting, thus preventing the direct fracture at the cut. This avoids scrapping the material at the beginning of the cutting process and ensures that the cutting device can effectively slit brittle special materials. At the same time, it can also be applied to the processing of flexible and hard materials, effectively preventing the strip material from shifting, undulating, or deforming and pulling during the cutting process, which would affect the processing accuracy. The strip material will have a smooth and even cut edge when it comes out of the discharge port of the cutting device, ensuring the processing accuracy and quality of the strip material. Therefore, the slitting machine described in this utility model has a simple structure and low cost. It does not require adjustments to parameters such as the type of cutting tool, meshing distance, and processing speed of the cutting device each time it processes materials, making operation more convenient, reducing the workload of workers, and improving production efficiency. When using it, only the clamping device needs to be adjusted according to the material type and thickness. This makes it suitable for slitting strips of various materials and thicknesses, including flexible materials, hard materials, and brittle special materials, ensuring the slitting accuracy and quality of the strips, improving its versatility, and facilitating the standardization of machine models.

[0008] As a preferred embodiment of this utility model, the clamping device includes a base, a fixed plate fixedly installed above the base, a movable plate disposed above the fixed plate, and an adjustment component connected to the movable plate and capable of moving the movable plate up and down relative to the fixed plate. The space between the movable plate and the fixed plate serves as a clamping opening, and the discharge end of each guide component passes through the clamping opening. The fixed plate supports the lower guide plate upwards, and the movable plate abuts against the upper guide plate. The movable plate and the fixed plate provide sufficient surface contact for the parts passing through the clamping opening. Its structure is simple, its setting is reasonable, and it is convenient to use.

[0009] As a preferred embodiment of this utility model, there are two adjustment components, which are symmetrically arranged at both ends of the movable plate. A connecting shaft connects the two adjustment components, so that the two adjustment components can be adjusted synchronously. Moreover, an adjustment handwheel is fixedly connected to the outer end of at least one adjustment component, which makes the adjustment of the clamping distance more convenient and helps to improve work efficiency.

[0010] As a preferred embodiment of this utility model, the adjusting component is a worm gear screw jack. The worm gear screw jack includes a fixed base mounted on a base, a worm gear mechanism housed within the fixed base, and a transmission shaft connected to the input end of the worm gear mechanism passing through the fixed base in a horizontal direction. An adjusting screw, connected to the output end of the worm gear mechanism, is positioned above the fixed base. The upper part of the adjusting screw extends upwards from the movable plate, and an adjusting nut is threaded onto the external thread of the adjusting screw, which is fixedly connected to the movable plate. The two ends of the connecting shaft are connected to the inner ends of the transmission shafts of the two worm gear screw jacks respectively via couplings. The adjusting handwheel is fixedly connected to the outer end of the transmission shaft of one of the worm gear screw jacks. This structure ensures stable operation of the movable plate's lifting process, high adjustment accuracy, and synchronous lifting adjustment on both sides. It can withstand large loads, has a long service life, and the use of couplings ensures smooth transmission and high reliability.

[0011] As a preferred embodiment of this utility model, a dial indicator is installed at the end of the fixed plate, and the measuring rod of the dial indicator abuts against the bottom of the movable plate, thereby enabling more precise adjustment of the clamping distance between the movable plate and the fixed plate of the clamping device.

[0012] As a preferred embodiment of this utility model, the cutting device includes two support frames arranged opposite each other on the left and right. Each support frame has an upper bearing seat and a lower bearing seat that can move up and down on its inner side. The upper roller is installed between the two upper bearing seats, and the lower roller is installed between the two lower bearing seats, so as to adjust the meshing distance between the upper and lower rollers to adapt to the processing of strips of different specifications and improve applicability.

[0013] As a preferred embodiment of this utility model, each set of cutting tools includes an upper blade mounted on the outside of the upper roller and a lower blade mounted on the outside of the lower roller. The meshing distance between the upper and lower blades does not exceed 1mm, which can avoid the situation where the resistance generated by the excessive meshing distance, plus the shearing force of each tool during processing, exceeds the torque of the cutting device, causing the cutting device to be overloaded and damaged during processing.

[0014] As a preferred embodiment of this utility model, the fixing frame is provided with upper and lower mounting plates above and below the strip feed inlet, respectively. Each guide component's upper and lower guide plates are provided with hooks at the feed end that are compatible with the upper and lower mounting plates, so that the upper and lower guide plates are hooked onto the upper and lower mounting plates respectively, making the structure easy to disassemble and assemble, and easier to install. If the upper and lower guide plates are damaged, they can be directly removed and replaced.

[0015] As a preferred embodiment of this utility model, a guide rail is provided on the discharge side of the cutting device along the infeed direction of the cutting strip, and the clamping device is slidably mounted on the guide rail, and its position can be easily adjusted by sliding the clamping device.

[0016] As a preferred embodiment of this utility model, a locking mechanism is also provided to lock or unlock the clamping device on the guide rail, which further facilitates locking and fixing the clamping device after the distance L is determined. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of this utility model will be further described in detail 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 based on this utility model are within the protection scope of this utility model.

[0028] It should be noted that if any directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) are involved in the embodiments of this utility model, such directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figures). If the specific posture changes, the directional indications will also change accordingly, and therefore should not be construed as a limitation on this utility model. In the description of the embodiments, unless otherwise explicitly specified and limited, terms such as "installation" and "connection" should be interpreted broadly. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Furthermore, in the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0029] The slitting machine provided in one embodiment of this utility model is as follows: Figures 1 to 6As shown, the device includes a cutting device 1, which comprises an upper roller 11 and a lower roller 12 arranged opposite to each other, and multiple sets of cutting blades 2 installed between the upper roller 11 and the lower roller 12 for cutting the strip material. Specifically, each set of cutting blades 2 includes an upper blade 21 and a lower blade 22 that mesh with each other. The upper blade 21 is installed on the outside of the upper roller 11, and the lower blade 22 is installed on the outside of the lower roller 12. The cutting device 1 has an inlet on the feeding side and an outlet on the discharging side. A horizontal guide for the strip material is provided between each set of cutting blades 2 along the direction of the strip material's entry and exit. The guide assembly 4 includes an inlet end for the strip entering the guide assembly and an outlet end for the strip leaving the guide assembly. Each guide assembly 4 comprises an upper guide plate 41 and a lower guide plate 42, which are opposite each other. Both the upper and lower guide plates can undergo elastic deformation under compression. A fixed frame 3 is provided on the inlet side of the cutting device 1, and a strip feed port 31 is provided on the fixed frame 3. The upper and lower guide plates of each guide assembly 4 are fixedly connected to the upper and lower sides of the strip feed port 31 at the inlet end, respectively. An adjustable clamping device 5 with a clamping distance is provided on the outlet side of the cutting device 1. By setting the guide assembly 4, the strip must enter the cutting device 1 through the strip feed port 31 of the fixed frame 3 when it enters for slitting processing. The strip moves along the upper guide plate 41 and the lower guide plate 42 in and out of the cutting device 1, providing a simple guiding function and preventing the strip from hanging directly downwards after exiting the outlet of the cutting device 1.

[0030] The discharge ends of each guide component 4 pass through the clamping device 5. The clamping device 5 adjusts the clamping distance between its upper and lower guide plates. The distance L between the clamping point of the clamping device 5 on the guide component 4 and the cutting point of the cutting device 1 (i.e., the meshing point of the upper and lower blades) is 150mm to 245mm. For processing brittle special materials and thin, hard materials, this distance L is preferably 150mm to 165mm; for processing flexible materials, this distance L is preferably 235mm to 245mm. By adopting the above-mentioned distance range, it is possible to ensure that the clamping device provides clamping and limiting for the strip while effectively preventing the strip from being vibrated and squeezed by the cutting tool, thus avoiding positional shifts, undulations, or deformation and pulling. This also prevents the strip from forming serrated edges, burrs, etc., and avoids material deformation or breakage due to excessive shearing force caused by excessively close clamping distance, ensuring processing accuracy and quality.

[0031] The clamping device 5 can be configured as an independent device, allowing it to move back and forth relative to the cutting device 1. This adjusts the distance L between the clamping point of the clamping device 5 and the cutting point of the cutting device 1, enabling the slitting machine to process different types of strip materials. When not in use, the clamping device 5 can be removed independently, making it flexible, convenient, and easy to move and store. For easy adjustment, a guide rail can be provided on the discharge side of the cutting device, running along the feed direction of the cut strip. The clamping device is slidably mounted on the guide rail, and the distance L can be changed by sliding the clamping device. Furthermore, a locking mechanism can be provided to lock or unlock the clamping device on the guide rail, facilitating locking and fixing the clamping device after the distance L is determined.

[0032] Specifically, the clamping device 5 includes a base 51, a fixed plate 52 fixedly mounted above the base 51, a movable plate 53 disposed above the fixed plate 52, and an adjustment assembly 6 connected to the movable plate 53 and capable of raising and lowering the movable plate 53 relative to the fixed plate 52. The space between the movable plate 53 and the fixed plate 52 serves as a clamping opening 55, providing sufficient surface contact for components passing through the clamping opening 55. Figure 1 , Figure 2 As shown, the discharge end of each guide component 4 passes through the clamping port 55, the fixed plate 52 supports the lower guide plate 42 upwards, and the movable plate 53 abuts against the upper guide plate 41.

[0033] Please see Figure 1 , Figure 6 There are two adjustment components 6, which are symmetrically arranged at both ends of the movable plate 53. A connecting shaft 7 connects the two adjustment components 6, so that the two adjustment components 6 can be adjusted synchronously. At least one adjustment component 6 has an adjustment handwheel 65 fixedly connected to its outer end. The clamping distance of the adjustment component 6 can be changed by rotating the adjustment handwheel 65, making the adjustment more convenient and improving efficiency.

[0034] like Figure 6As shown, the adjusting component 6 is a worm gear screw jack. The worm gear screw jack includes a fixed base 61 mounted on a base 51. A worm gear mechanism is housed within the fixed base 61. A transmission shaft 64, connected to the input end of the worm gear mechanism, passes horizontally through the fixed base 61. An adjusting screw 62, connected to the output end of the worm gear mechanism, is positioned above the fixed base 61. The upper part of the adjusting screw 62 extends upwards from the movable plate 53. An adjusting nut 63 is threaded onto the external thread of the adjusting screw 62 and is fixedly connected to the movable plate 53. Using a worm gear screw jack as the adjusting component 6 ensures stable operation of the movable plate 53 during lifting, provides high adjustment accuracy, can withstand large loads, and has a long service life. The two ends of the connecting shaft 7 are respectively connected to the inner end of the drive shaft 64 of the two worm gear screw jacks via couplings 71. The couplings 71 make the transmission process smooth and highly reliable. The adjusting handwheel 65 is fixedly connected to the outer end of the drive shaft 64 of one of the worm gear screw jacks so that force can be applied to the drive shaft 64, so that the worm gear screw jacks on both sides can be adjusted synchronously.

[0035] In use, this utility model allows for adjustment of the position of the clamping device 5 of the slitting machine relative to the discharge end of the guide assembly 4 according to the material of the strip to be processed. This changes the distance L between the clamping point of the clamping device 5 on the guide assembly 4 and the cutting point of the cutting device 1, adapting to the processing of different materials. The clamping device 5 provides clamping and limiting for the strip passing through the guide assembly 4 on the discharge side of the cutting device 1. Based on the thickness of the strip, the adjusting component 6 is used to adjust the distance between the movable plate 53 and the fixed plate 52 in the clamping device 5, ensuring sufficient upper and lower limiting for the strip and improving its stability. This allows the slitting machine to perform the corresponding cutting work and ensures processing quality.

[0036] As a specific embodiment, this method is applied to brittle special materials such as epoxy resin boards, semiconductor glass cloth boards, and circuit board substrates, as well as thin, hard materials such as stainless steel and copper plates, referring to... Figure 1 , Figure 2 As shown, the clamping device 5 can be moved closer to the cutting device, so that the spacing L is preferably adjusted to 150mm~165mm, so that the discharge end of the guide component 4 passes through the clamping port 55 of the clamping device 5, and the end of the guide component 4 protrudes from the clamping port 55. The fixed plate 52 supports the lower guide plate 42 upward, and the movable plate 53 abuts against the upper guide plate 41 downward, so that the upper guide plate 41 can be deformed under the pressure of the movable plate 53. By adjusting the adjusting component 6 such as the worm gear screw jack, the clamping device 5 can make full surface contact with the upper and lower sides of the guide component 4, changing the clamping spacing between the upper and lower guide plates at the extrusion point. The upper and lower guide plates then make surface contact with the upper and lower sides of the strip passing through the guide component 4, respectively, to provide a suitable upper and lower limiting function.

[0037] When using the slitting machine with the above structure, firstly, the beginning end of the strip is inserted between the upper and lower rollers of the cutting device 1 from the feed side, and the strip is placed in the guide assembly 4; then, the discharge end of the guide assembly 4 is inserted into the clamping port 55 of the clamping device 5. By adjusting the worm gear screw jack, the movable plate 53 is moved up and down relative to the fixed plate 52, so that the movable plate 53 of the clamping device 5 is in close contact with the upper guide plate 41, while the fixed plate 52 supports the lower guide plate 42. At this time, if... Figure 2 As shown, the upper and lower guide plates maintain their initial spacing and are positioned precisely within the clamping opening 55 between the movable plate 53 and the fixed plate 52. Continuing to adjust the worm gear screw jack, the movable plate 53 moves downward, changing the clamping distance. At this point, the upper guide plate 41 deforms due to the pressure from the movable plate 53, allowing the lower surface of the upper guide plate 41 near the pressure point to be closer to the top of the strip. Depending on the strip thickness, the movable plate 53 continues to move downward, eventually adjusting until the lower surface of the upper guide plate 41 near the pressure point is positioned to press against the upper surface of the strip. The upper and lower guide plates can make full contact with the strip at the extrusion point, providing sufficient clamping and limiting function for the strip. Then, the cutting device 1 cuts the strip. Under the action of each set of cutting blades 2, the strip is cut into strips and moves towards the discharge side. The above-mentioned structure of the clamping device 5 can prevent the strip from shifting or fluctuating due to the influence of the cutting device 1 during the cutting process, thus improving its stability during the cutting process. At the same time, it does not affect the passage of the strip between the upper and lower guide plates. The strip can pass through the inlet and outlet of the cutting device 1 normally without obstruction.

[0038] The structure described in the above embodiments is applicable to processing brittle special materials (thickness 0.2-3mm) and thin hard materials (thickness 0.2-0.5mm). This effectively prevents the strip material from shifting, undulating, or deforming due to tool vibration during cutting. For brittle special materials, it avoids positional shifts and deformation caused by tool vibration and compression during cutting, which could lead to breakage at the cut and render the material unusable from the outset. This slitting process for brittle special materials is simpler and more convenient, eliminating the need for complex machine modifications and effectively reducing costs. It is also suitable for processing thin hard materials, preventing breakage and burrs during processing. This ensures that the slitting material exits the cutting device 1 with a smooth, even cut edge, improving processing accuracy and quality. The processing accuracy can reach ≤0 to -0.2mm, and the workpiece burr is ≤0.1mm.

[0039] As another specific embodiment, for processing flexible materials such as glass wrapping paper, clothing fabrics, flexible cardboard, flexible / rigid films, and plastic sheets, the clamping device 5 can be moved away from the cutting device, so that the spacing L is preferably adjusted to 235mm to 245mm. To further reduce damage to flexible materials and facilitate their processing, refer to... Figure 7 , Figure 8 As shown, the discharge end of the guide assembly 4 is aligned with the clamping port 55 of the clamping device 5, and the upper surface of the fixing plate 52 is horizontally aligned with the lower surface of the lower guide plate 42 of the guide assembly 4, so that the strip enters the clamping port 55 of the clamping device 5 after leaving the discharge end of the guide assembly 4. By adjusting the adjusting components 6 such as the worm gear screw jack, the clamping distance of the clamping port 55 is changed, so that the clamping device 5 directly provides a suitable upper and lower limiting effect on the upper and lower sides of the strip.

[0040] When using the slitting machine with the above structure, the clamping device 5 is moved to the discharge side of the cutting device 1, with its clamping port 55 facing the discharge end of the guide assembly 4. The upper surface of the fixed plate 52 is horizontally aligned with the lower surface of the lower guide plate 42 of the guide assembly 4, so that the processed strip passes through the guide assembly 4 and leaves the discharge end before entering the clamping port 55 of the clamping device 5. Then, by adjusting the worm gear screw jack, the movable plate 53 is moved up and down relative to the fixed plate 52, changing the distance between the movable plate 53 and the fixed plate 52 until it can provide sufficient upper and lower limit for the strip, so as to prevent the strip from being affected by the cutting device 1 during the cutting process and causing positional deviation, undulation, etc., so that the strip cut edge is flat, improving its stability during the cutting process, and the strip can pass through the inlet and outlet of the cutting device 1 normally without obstruction.

[0041] The structure described in the above embodiments is applicable to processing flexible materials. The strip thickness is defined as B. For flexible materials with a thickness of 0.2-0.5 mm, such as glass wrapping paper and clothing fabric, the distance between the movable plate 53 and the fixed plate 52 can be adjusted to the strip thickness B + 0.2 mm. For flexible materials with a thickness of 0.5-3 mm, such as soft cardboard, flexible / rigid films, and plastic sheets, the distance between the movable plate 53 and the fixed plate 52 can be adjusted to the strip thickness B + 0.1 mm to ensure smooth material output. When processing flexible materials, a certain traction force is provided manually or mechanically on the side of the clamping device 5 away from the cutting device 1 to pull the material, further preventing the flexible material from being caught in the cutting tool. Through the above treatment, the deformation of the flexible material caused by the cutting tool squeezing the material during the slitting process can be eliminated, or the cut position can be serrated due to insufficient shear force. This ensures that the flexible material has a smooth and even cut edge when it comes out of the discharge port of the cutting device 1 after slitting. It also avoids processing accidents such as material segment breakage. The structure is simple and easy to operate, ensuring processing accuracy and quality. Its processing accuracy can reach ≤0 to -0.2mm, and the workpiece burr is ≤0.1mm.

[0042] For thicker, harder materials (0.5-3mm thick), such as stainless steel and copper plates, which have sufficient rigidity, the cutting device 1 of the slitting machine can be used directly for slitting without the need for the clamping device 5 to adjust and limit the guide component 4.

[0043] like Figure 6 As shown, a dial indicator 54 is installed at the end of the fixed plate 52. The measuring rod of the dial indicator 54 abuts against the bottom of the movable plate 53. By setting the dial indicator 54, the user can more accurately adjust the clamping distance between the movable plate 53 and the fixed plate 52 of the clamping device 5, ensuring that it can provide sufficient limiting effect during use.

[0044] like Figure 4 As shown, the cutting device 1 includes two support frames 13 arranged opposite each other on the left and right. Each support frame 13 has an upper bearing seat 14 and a lower bearing seat 15 that can move up and down on its inner side. The upper roller 11 is installed between the two upper bearing seats 14, and the lower roller 12 is installed between the two lower bearing seats 15. This allows the upper roller 11 and the lower roller 12 to be adjusted in the vertical direction, thereby changing the vertical meshing distance between the upper blade 21 and the lower blade 22 of each set of cutting tools 2, so as to adapt to the processing of strip materials of different specifications and improve applicability.

[0045] To enable the cutting device 1 to better cut strips of various materials, preferably, all cutting tools 2 use Cr12MoV grade cutting tools. The rotation speed of the upper and lower blades of each set of cutting tools 2 is set to 20 revolutions per minute during processing to adapt to different materials and ensure processing accuracy. Since there is resistance when the upper blade 21 and its corresponding lower blade 22 mesh, if the meshing distance between them is too large, the resulting resistance plus the shear force during processing will exceed the torque of the cutting device 1, easily causing overload and damage. Therefore, to ensure normal operation, the meshing distance between the upper and lower blades of each set of cutting tools 2 should not exceed 1mm. These parameters do not require further adjustment after initial setup.

[0046] For metal sheets of different specifications, in order to obtain better cutting results, when the meshing distance between the upper and lower blades of each group is less than 0.5mm, it is suitable for processing metal sheets of 0.5mm-1mm; when the meshing distance between the upper and lower blades of each group is between 0.5mm and 1mm, it is suitable for processing metal sheets of 1mm-3mm.

[0047] like Figure 4 , Figure 5 As shown, the fixing frame 3 is provided with an upper mounting plate 32 and a lower mounting plate 33 above and below the strip feed inlet 31, respectively. Each guide component 4 has a hook part 43 at the feed end that is compatible with the upper and lower mounting plates, so that the upper and lower guide plates are hooked onto the upper and lower mounting plates respectively. Its structure is simple, easy to disassemble and assemble, and more convenient to install. If the upper and lower guide plates are damaged, they can be directly removed and replaced.

[0048] In summary, the slitting machine provided by this utility model utilizes the guide component 4 to initially guide and limit the strip material entering the cutting device 1 for processing, preventing the strip material from drooping directly on the discharge side of the cutting device 1. A clamping device 5 is provided on the discharge side of the cutting device 1 to clamp and limit the strip material passing through the guide component 4. The distance L between the clamping point of the clamping device 5 on the guide component 4 and the cutting point of the cutting device 1 is set to 150mm to 245mm. This distance L can be manually adjusted according to the material type of the strip, enabling the slitting machine to process strip materials of corresponding materials. The upper and lower clamping distance of the clamping device 5 can be adjusted according to the thickness of the strip material to adapt it to strip materials of different thicknesses. After the above adjustments, the strip can pass normally through the guide assembly 4 and be slit by the cutting device 1, while also receiving sufficient surface contact on the discharge side of the cutting device 1. This ensures adequate upper and lower limiting, providing stability for the strip during the cutting process. For brittle special materials, this prevents the material from shifting or deforming due to the vibration and compression of the cutting tool during cutting, thus avoiding the direct fracture at the cut and the resulting scrapping of the material. This ensures that the cutting device 1 can effectively slit brittle special materials. It is also suitable for processing flexible and hard materials, effectively preventing the strip from shifting, undulating, or deforming during the cutting process, which could affect the processing accuracy and ensure the processing accuracy and quality of the strip.

[0049] Therefore, the slitting machine of this utility model has a simple structure and low cost. It does not require adjustment of parameters such as the type of cutting tool, meshing distance, and processing speed of the cutting device 1 every time it processes materials, making operation more convenient, reducing the workload of workers, and improving production efficiency. When using it, only the clamping device 5 needs to be adjusted according to the material type and thickness. It can be used to slitting strips of various materials and thicknesses, including flexible materials, hard materials, and brittle special materials, ensuring the slitting accuracy and quality of the strips, improving its versatility, and facilitating the standardization of machine models.
