Description

Technical Field

[0001] The invention relates to the technical field of material slitting equipment, and in particular to a slitting machine. Background Art

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

[0003] At present, the commonly used slitting machines on the market are mainly used for processing flexible materials such as cloth strips, cardboard, cellophane, aluminum foil, film, etc., and for processing metal hard materials such as steel plates, stainless steel plates, copper plates, etc., and for insulating brittle special materials containing glass fibers such as epoxy resin plates and semiconductor glass cloth plates commonly used in industries such as generators and motors, due to their large brittleness and other characteristics, they have very high requirements for processing precision. If the above-mentioned slitting machines are used directly to process brittle special materials, since their high-speed rotating cutting tools usually produce certain vibrations during cutting, the material will become unstable during cutting due to the vibration and extrusion of the tool, and its position will shift and deform, and then fracture marks will be directly produced at the incision, until the entire sheet of material breaks irregularly and is scrapped, seriously affecting the processing quality. Therefore, in order to process the above materials smoothly, the existing slitting machine models need to be modified in actual use to make them dedicated to processing a certain type of brittle special materials. However, the modification is difficult and expensive, and most of them are only modified for cutting a certain type of brittle special materials, and cannot be applied to other brittle special materials. Its versatility is greatly limited.

[0004] In addition, even when the existing slitting machine is used for ordinary strips, due to the differences in the material and thickness of different types of strips, it is also necessary to adjust the cutting device of the slitting machine according to the strips of different materials and thicknesses, such as adjusting the meshing distance between the upper and lower cutters, changing the processing speed of the cutters, changing the brand of the cutters, etc., so that the shearing force is suitable for cutting the corresponding strips, and after the above parameters are determined, the slitting machine can only be used to process specific materials and thickness ranges. Otherwise, if it is directly used to process unsuitable types of strips, it will affect its slitting processing quality and make it difficult to meet the needs. For example, when the existing slitting machine used to process thicker hard materials is directly used to cut thinner hard materials or flexible materials, since the rigidity of flexible materials and thinner hard materials is less than that of thicker hard materials, these materials are also prone to instability when being cut by the cutting tool, and certain position offsets, fluctuations or deformation pulling occur, which leads to jagged edges, burrs, etc. on the cutting edges of the strips, making it difficult to form smooth straight edges, resulting in low processing accuracy, and even segmented fracture processing accidents may occur for some flexible materials. The above problems also limit the versatility of the slitting machine for different materials and thicknesses. Each time different types of strips are cut, the cutting device of the slitting machine needs to be adapted and adjusted in advance. The size and weight of the knife shaft, cutting tool, etc. are usually large, which makes each replacement operation complicated and inconvenient, increases the workload of workers, affects production and processing efficiency, and has great limitations in industry applications. Summary of the invention

[0005] The purpose of the present invention is to overcome the problems existing in the above-mentioned prior art and to provide a slitting machine that can be adapted to process strips of different materials and thicknesses, so as to improve its versatility and processing efficiency.

[0006] The slitting machine includes a cutting device, which includes an upper roller and a lower roller arranged opposite to each other, and a plurality of cutting tools installed between the upper and lower rollers and opposite to each other for cutting strips. A guide assembly for passing strips is horizontally penetrated between each group of cutting tools along the in and out direction of the cutting strips. The guide assemblies include an upper guide plate and a lower guide plate opposite to each other. A fixed frame is arranged on the feeding side of the cutting device, and a strip feeding port is arranged on the fixed frame. The upper and lower guide plates of each guide assembly are respectively fixedly connected to the upper and lower sides of the strip feeding port at the feeding end. A clamping device with an adjustable clamping distance is arranged on the discharging side of the cutting device. The discharging end of each guide assembly passes through the clamping device, and the clamping distance of the upper and lower guide plates thereof is adjusted by the clamping device. 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 to 245mm.

[0007] The slitting machine provided by the present invention utilizes a guide component to play a preliminary guiding and limiting role for the strip entering the cutting device for processing, thereby preventing the strip from directly sagging on the discharge side of the cutting device, and by arranging a clamping device on the discharge side of the cutting device, the clamping device provides clamping and limiting for the strip passing through the guide component, and the distance L between the clamping position of the clamping device on the guide component and the cutting position of the cutting device is set to 150mm~245mm. The spacing L can be manually adjusted according to the material type of the strip, so that the slitting machine can process strips of corresponding materials, ensuring that the clamping limit of the clamping device can effectively prevent the strip from vibrating due to the vibration and extrusion of the tool; according to the thickness of the strip, the upper and lower clamping spacings of the clamping device are adjusted to make it suitable for strips of different thicknesses. After the above adjustment, the strip can pass through the guide assembly normally and be cut into strips by the cutting device, while being sufficiently limited by the upper and lower limiters of the clamping device on the discharge side of the cutting device, so that the stability of the strip can be maintained during the cutting process. For brittle special materials, it can prevent the material from being affected by the vibration and extrusion of the tool during cutting, causing position displacement and deformation, and then directly causing fracture marks at the incision, thereby avoiding the scrapping of the material at the beginning of cutting, and ensuring that the cutting device can effectively strip the brittle special materials; at the same time, it can also be suitable for processing flexible materials and hard materials, and can effectively prevent the above-mentioned strips from being easily displaced, undulating or deformed and pulled during the cutting process, thereby affecting the processing accuracy. When the strip comes out of the discharge port of the cutting device, it can have a smooth and smooth cut edge, ensuring the processing accuracy and quality of the strip. Therefore, the slitting machine described in the present invention has a simple structure and low cost. It does not need to adjust the parameters such as the tool type, meshing distance, and processing speed of the cutting device every time the material is processed, making the operation more convenient, reducing the workload of workers, and improving production efficiency. When in use, it is only necessary to adjust the clamping device accordingly according to the material type and thickness, so that it can be used for slitting processing of strips of various materials and thicknesses including flexible materials, hard materials, brittle special materials, etc., to ensure the slitting processing accuracy and quality of the strips, improve its versatility, and facilitate the unification of machine models.

[0008] As a preferred embodiment of the present invention, the clamping device includes a base, a fixed plate fixedly installed above the base, a movable plate arranged above the fixed plate, and an adjusting component connected to the movable plate and capable of lifting and moving the movable plate relative to the fixed plate. The movable plate and the fixed plate serve as a clamping opening, the discharge end of each guide component passes through the clamping opening, the fixed plate supports the lower guide plate upward, the movable plate abuts against the upper guide plate, and the movable plate and the fixed plate provide sufficient surface contact for the components passing through the clamping opening. The structure is simple, the arrangement is reasonable, and it is easy to use.

[0009] As a preferred solution of the present invention, there are two adjustment components, which are symmetrically arranged at both ends of the movable plate. A connecting shaft is connected between the two adjustment components so that the two adjustment components can be adjusted synchronously, and 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 solution of the present invention, the adjustment component is a worm gear screw lift, which includes a fixed seat installed on a base, a worm gear mechanism is arranged in the fixed seat, a transmission shaft connected to the input end of the worm gear mechanism is passed through the fixed seat in the horizontal direction, an adjustment screw connected to the output end of the worm gear mechanism is arranged above the fixed seat, the upper part of the adjustment screw extends upward from the movable plate, the external thread of the adjustment screw is sleeved with an adjustment nut, and the adjustment nut is fixedly connected to the movable plate; the two ends of the connecting shaft are respectively connected to the transmission shafts at the inner ends of the two worm gear screw lifts through a coupling, and the adjustment handwheel is fixedly connected to the transmission shaft at the outer end of one of the worm gear screw lifts. The above structure can make the lifting process of the movable plate stable and have high adjustment accuracy, and both sides can be lifted and lowered synchronously, can withstand large loads, and have a long service life. The use of a coupling can make the transmission process smooth and highly reliable.

[0011] As a preferred solution of the present invention, a micrometer is installed at the end of the fixed plate, and the measuring rod of the micrometer abuts upward against the bottom of the movable plate, so that the clamping distance between the movable plate and the fixed plate of the clamping device can be adjusted more accurately.

[0012] As a preferred embodiment of the present invention, the cutting device includes two support frames arranged opposite to each other on the left and right sides, and an upper bearing seat and a lower bearing seat that can move up and down are provided on the inner side of each support frame.

The meshing distance between the upper and lower blades does not exceed 1 mm. This can avoid the situation where the cutting device is overloaded and damaged during processing due to the resistance generated by the excessive meshing distance and the shear force of each tool during processing being greater than the torque of the cutting device.

[0014] As a preferred solution of the present invention, the fixing frame is provided with upper and lower mounting plates above and below the strip feed port, respectively.

DETAILED DESCRIPTION

[0019] The technical scheme in the embodiment of the present invention is further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiment is only a part of the embodiment of the present invention, rather than all the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field based on the present invention belong to the scope of protection of the present invention.

[0020] It should be noted that if there are directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly, so it cannot be understood as a limitation on the present invention. In the description of the embodiments, unless otherwise clearly specified and limited, the terms such as "installation" and "connection" should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In addition, in the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly specified and limited.

[0021] A slitting machine provided by an embodiment of the present invention is as follows Figures 1 to 6As shown, it includes a cutting device 1, which includes an upper roller 11 and a lower roller 12 arranged opposite to each other, and a plurality of groups of cutting tools 2 installed between the upper roller 11 and the lower roller 12 and opposite to each other for cutting the strip. Specifically, each group of cutting tools 2 includes an upper blade 21 and a lower blade 22 meshed with each other, the upper blade 21 is installed on the outer side of the upper roller 11, and the lower blade 22 is installed on the outer side of the lower roller 12; the cutting device 1 has a feeding port on the feeding side and a discharging port on the discharging side; each group of cutting tools 2 is horizontally penetrated with a passable strip along the inlet and outlet direction of the cutting strip. A guide assembly, wherein the end where the strip enters the guide assembly is used as its feed end, and the end where the strip leaves the guide assembly is used as its discharge end; the guide assembly 4 includes an upper guide plate 41 and a lower guide plate 42 which are opposite to each other, and both the upper and lower guide plates can undergo a certain elastic deformation under the action of extrusion, a fixed frame 3 is provided on the feed side of the cutting device 1, and a strip feed port 31 is provided on the fixed frame 3, and the upper and lower guide plates of each guide assembly 4 are respectively fixedly connected to the upper and lower sides of the strip feed port 31 at the feed end, and a clamping device 5 with an adjustable clamping distance is provided on the discharge side of the cutting device 1. By providing the above-mentioned guide assembly 4, the strip must enter from the strip feed port 31 of the fixed frame 3 when entering the cutting device 1 for strip processing, so that the strip enters and exits the cutting device 1 along the upper guide plate 41 and the lower guide plate 42, which plays a simple guiding role and prevents the strip from directly drooping down after coming out of the discharge port of the cutting device 1.

[0022] The discharge end of each guide assembly 4 passes through the clamping device 5, and the clamping distance of the upper and lower guide plates is adjusted by the clamping device 5. The distance L between the clamping position of the clamping device 5 on the guide assembly 4 and the cutting position of the cutting device 1 (i.e., the meshing position of the upper and lower blades) is 150mm-245mm. Among them, for processing brittle special materials and thin hard materials, the spacing L is preferably 150mm-165mm; for processing flexible materials, the spacing L is preferably 235mm-245mm. By adopting the above spacing range, it can ensure that the clamping device provides clamping and limiting for the strip, and effectively prevent the strip from vibrating due to the vibration and extrusion of the tool, resulting in position deviation, fluctuation or deformation pulling, avoiding the formation of serrated edges, cutting edges, burrs, etc. when cutting the strip, and also avoiding the deformation or breakage of the material due to excessive shear force caused by the clamping distance being too close, thereby ensuring the processing accuracy and quality.

[0023] The clamping device 5 can be set as an independent device, so that it can move forward and backward relative to the cutting device 1 to adjust the distance L between the clamping position of the clamping device 5 on the guide assembly 4 and the cutting position of the cutting device 1, so that the slitting machine can be adapted to process different types of strips. When not processing, the clamping device 5 can be taken out separately, making it flexible and convenient to use, move and store. In order to facilitate adjustment, a guide rail set along the in and out direction of the cut strip can be set on the discharge side of the cutting device, and the clamping device is slidably installed on the guide rail, and the spacing L is changed by sliding the clamping device. In addition, a locking mechanism that can lock or unlock the clamping device on the guide rail can be set, so that the clamping device can be locked and fixed after the spacing L is determined.

[0024] 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 component 6 connected to the movable plate 53 and capable of lifting and moving the movable plate 53 relative to the fixed plate 52. The movable plate 53 and the fixed plate 52 serve as a clamping opening 55, and the movable plate 53 and the fixed plate 52 provide sufficient surface contact for the components passing through the clamping opening 55. Figure 1 , Figure 2 As shown, the discharge end of each guide assembly 4 passes through the clamping opening 55 , the fixed plate 52 supports the lower guide plate 42 upward, and the movable plate 53 abuts against the upper guide plate 41 .

[0025] See also Figure 1 , Figure 6 There are two adjusting components 6, which are symmetrically arranged at both ends of the movable plate 53. A connecting shaft 7 is connected between the two adjusting components 6, so that the two adjusting components 6 can be adjusted synchronously, and an adjusting hand wheel 65 is fixedly connected to the outer end of at least one adjusting component 6. The clamping spacing of the adjusting component 6 can be changed by rotating the adjusting hand wheel 65, making the adjustment more convenient and improving the efficiency.

[0026] like Figure 6As shown, the adjustment component 6 is a worm gear screw lift, which includes a fixed seat 61 installed on the base 51, a worm gear mechanism is arranged in the fixed seat 61, a transmission shaft 64 connected to the input end of the worm gear mechanism is passed through the fixed seat 61 in the horizontal direction, and an adjustment screw 62 connected to the output end of the worm gear mechanism is arranged above the fixed seat 61, the upper part of the adjustment screw 62 extends upward from the movable plate 53, and the external thread of the adjustment screw 62 is sleeved with an adjustment nut 63, and the adjustment nut 63 is fixedly connected to the movable plate 53. Using the worm gear screw lift as the adjustment component 6 can make the lifting process of the movable plate 53 stable, have high adjustment accuracy, can withstand large loads, and have a long service life. The two ends of the connecting shaft 7 are respectively connected to the transmission shaft 64 at the inner end of the two worm gear screw lifts through the coupling 71. The coupling 71 makes the transmission process smooth and reliable. The adjusting hand wheel 65 is fixedly connected to the transmission shaft 64 at the outer end of one of the worm gear screw lifts so as to apply force to the transmission shaft 64 so that the worm gear screw lifts on both sides can be raised and lowered synchronously.

[0027] When the present invention is in use, the position of the clamping device 5 of the slitting machine relative to the discharge end of the guide component 4 can be adjusted according to the material of the strip to be processed, thereby changing 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 to adapt to the processing of different materials. The clamping device 5 provides a clamping limit for the strip passing through the guide component 4 on the discharge side of the cutting device 1, and according to the thickness of the strip, the adjustment component 6 is used to adjust the distance between the movable plate 53 in the clamping device 5 and the fixed plate 52 accordingly, so that the strip is subject to sufficient upper and lower limit effects and its stability is improved, so that the slitting machine can perform corresponding cutting work and ensure the processing quality.

[0028] As a specific embodiment, for brittle special materials such as epoxy resin boards, semiconductor glass cloth boards, circuit board substrates, and thin hard materials such as stainless steel, copper and other metal sheets, refer to Figure 1 , Figure 2 As shown, the clamping device 5 can be moved toward the direction close to the cutting device so that the spacing L is preferably adjusted to 150 mm to 165 mm, so that the discharge end of the guide component 4 is inserted into 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 extrusion of the movable plate 53. By adjusting the adjustment components 6 such as the worm gear screw lifter, the clamping device 5 can make sufficient surface contact with the upper and lower sides of the guide component 4, and change the clamping distance 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, providing an adaptive upper and lower limit function for it.

[0029] When the slitting machine with the above structure is used, firstly, the leading end of the strip is passed through the upper and lower rollers of the cutting device 1 from the feeding side of the cutting device 1, and the strip is placed in the guide assembly 4; then, the discharging end of the guide assembly 4 is passed through the clamping opening 55 of the clamping device 5, and the movable plate 53 is moved up and down relative to the fixed plate 52 by adjusting the worm gear screw lifter, so that the movable plate 53 of the clamping device 5 is in close contact with the upper guide plate 41, and the fixed plate 52 supports the lower guide plate 42. At this time, Figure 2 As shown, the initial spacing between the upper and lower guide plates is maintained, and they just fit into the clamping opening 55 between the movable plate 53 and the fixed plate 52; the worm gear screw elevator is continuously adjusted to move the movable plate 53 downward to change the clamping spacing. At this time, the upper guide plate 41 will be deformed to a certain extent due to the extrusion of the movable plate 53, so that the lower surface of the upper guide plate 41 near the extrusion point can be closer to the top of the strip. According to the thickness of the strip, the movable plate 53 is further moved downward, and finally it can be adjusted to a position where the lower surface of the upper guide plate 41 near the extrusion point fits and presses on the upper surface of the strip, that is, The upper and lower guide plates can fully contact the strip between the extrusion points, providing sufficient upper and lower clamping and limiting effects on the strip therein; then the cutting device 1 cuts the strip therein, and the strip is cut into strips and moved to the discharge side under the action of each group of cutting tools 2. The above-mentioned structure of the clamping device 5 can prevent the strip from being affected by the cutting device 1 during the cutting process. Position deviation, fluctuations and the like, improve its stability during the cutting process, and at the same time do 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 hindrance.

[0030] The structure described in the above embodiment can be applied to the processing of brittle special materials (thickness 0.2-3mm) and thin hard materials (thickness 0.2-0.5mm). Thus, the above-mentioned strip can be effectively prevented from being offset, fluctuating or deformed and pulled by the vibration of the tool during the cutting process. For brittle special materials, it can be avoided that the material is offset and deformed due to the vibration and extrusion of the tool during cutting, and then the fracture marks are directly generated at the incision, causing the material to be scrapped from the beginning, making the strip processing of brittle special materials simpler and more convenient, without the need for complex special machine transformation, effectively reducing costs, and also suitable for processing thin hard materials, avoiding fragmentation, burrs, etc. during the processing process, ensuring that the above-mentioned materials can have smooth and smooth cutting edges when they come out of the discharge port of the cutting device 1 after stripping, improving the processing accuracy and quality, and the processing accuracy can reach ≤0~-0.2mm, and the workpiece burr ≤0.1mm.

[0031] As another specific embodiment, for processing flexible materials such as glass packaging paper, clothing fabrics, soft cardboard, soft / hard films, plastic plates, etc., the clamping device 5 can be moved away from the cutting device so that the spacing L is preferably adjusted to 235mm to 245mm. In order to further reduce damage to the flexible material and facilitate processing of the flexible material, reference can be made to Figure 7 , Figure 8 As shown, the discharge end of the guide assembly 4 is aligned with the clamping opening 55 of the clamping device 5, and 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 strip enters the clamping opening 55 of the clamping device 5 after leaving the discharge end of the guide assembly 4. By adjusting the adjusting assembly 6 such as the worm gear screw lifter, the clamping spacing of the clamping opening 55 is changed, so that the clamping device 5 directly provides an adaptive upper and lower limit function for the upper and lower sides of the strip.

[0032] When the slitting machine of the above structure is in use, the clamping device 5 is moved to the discharge side of the cutting device 1, and its clamping opening 55 is opposite to the discharge end of the guide assembly 4, and 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 along the guide assembly 4 and leaves the discharge end, and then enters the clamping opening 55 of the clamping device 5, and then the movable plate 53 is raised and lowered relative to the fixed plate 52 by adjusting the worm gear screw lifter to change the distance between the movable plate 53 and the fixed plate 52 until sufficient upper and lower limit functions can be provided for the strip therein, so as to prevent the strip from being affected by the cutting device 1 during the cutting process and experiencing positional displacement, fluctuations, etc., so that the strip edges are smooth, the stability of the strip during the cutting process is improved, and the strip can pass through the inlet and outlet of the cutting device 1 normally without hindrance.

[0033] The structure described in the above embodiment can be applied to the processing of flexible materials, wherein the thickness of the strip is defined as B. For flexible materials with a thickness of 0.2-0.5 mm, such as glass packaging paper, clothing fabrics, etc., the spacing 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, soft / hard film, plastic board, etc., the spacing between the movable plate 53 and the fixed plate 52 can be adjusted to the strip thickness B+0.1 mm to ensure smooth discharge of the flexible material. When processing flexible materials, a certain traction force is provided on the side of the clamping device 5 away from the cutting device 1 by manpower or machine to pull the material, so as to further prevent the flexible material from being rolled into the cutting tool. Through the above-mentioned treatment, deformation of the flexible material caused by the cutting tool squeezing the material during the stripping process, or the serrated incision position caused by insufficient shear force can be eliminated, so that the flexible material can have a smooth and smooth cutting edge when it comes out of the discharge port of the cutting device 1 after stripping, and the processing accident of material segment breakage can be avoided. It has a simple structure and is easy to operate, ensuring processing accuracy and quality. Its processing accuracy can reach ≤0~-0.2mm, and the workpiece burr is ≤0.1mm.

[0034] For thicker hard materials (thickness 0.5-3mm), such as stainless steel, copper and other metal sheets, whose materials have sufficient rigidity, the cutting device 1 of the slitting machine can be used directly for slitting processing, and there is no need to adjust the guide component 4 up and down through the clamping device 5.

[0035] like Figure 6 As shown, a micrometer 54 is installed at the end of the fixed plate 52, and the measuring rod of the micrometer 54 is upwardly abutted against the bottom of the movable plate 53. By setting the micrometer 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 to ensure that it can provide sufficient limiting effect when in use.

[0036] like Figure 4 As shown, the cutting device 1 includes two support frames 13 which are arranged opposite to each other on the left and right sides, and an upper bearing seat 14 and a lower bearing seat 15 which can be moved up and down are provided on the inner side of each support frame 13. 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, so that the positions of the upper roller 11 and the lower roller 12 in the vertical direction can be adjusted, and the upper and lower meshing distances between the upper blades 21 and the lower blades 22 of each group of cutting tools 2 can be changed to adapt to the processing of strips of different specifications and improve applicability.

[0037] In order to enable the above-mentioned cutting device 1 to better cut and strip the above-mentioned strips of various different materials, preferably, the tool brand used by each cutting tool 2 is Cr12MoV; the rotation speed of the upper and lower blades of each group of cutting tools 2 during processing is set to 20 revolutions / minute, so as to adapt to the processing of different materials and ensure the processing accuracy. Since there will be a certain resistance when the upper blade 21 and the corresponding lower blade 22 of each group of cutting tools 2 are engaged, if the engagement distance between the upper blade 21 and the corresponding lower blade 22 is too large, the resistance generated plus the shear force of each tool during processing will be greater than the torque of the cutting device 1, which is easy to cause the cutting device 1 to be overloaded during the strip cutting process, resulting in its damage. Therefore, in order to ensure the normal operation of the equipment, the engagement distance between the upper and lower blades of each group of cutting tools 2 does not exceed 1mm. The above parameters do not need to be adjusted after adjustment.

[0038] For metal sheets of different specifications, in order to obtain better cutting effects, 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.

[0039] 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 material feed port 31, respectively. The upper and lower guide plates of each guide assembly 4 are provided with hooking portions 43 adapted to the upper and lower mounting plates at the feeding end, so that the upper and lower guide plates are hooked on the upper and lower mounting plates, respectively. The structure is simple, easy to disassemble and assemble, and more convenient to install. After the upper and lower guide plates are damaged, they can be directly removed and replaced.

[0040] In summary, the slitting machine provided by the present invention utilizes the guide component 4 to play a preliminary guiding and limiting role for the strip entering the cutting device 1 for processing, so as to prevent the strip from directly sagging on the discharge side of the cutting device 1, and arranges a clamping device 5 on the discharge side of the cutting device 1 to provide clamping and limiting for the strip passing through the guide component 4, and the distance L between the clamping point of the guide component 4 of the clamping device 5 and the cutting point of the cutting device 1 is set to 150mm~245mm, and the spacing L can be manually adjusted according to the material type of the strip, so that the slitting machine can process strips of corresponding materials; according to the thickness of the strip, the upper and lower clamping spacing of the clamping device 5 is adjusted to make it suitable for strips of different thicknesses. After the above adjustment, the strip can pass through the guide assembly 4 normally and be cut into strips by the cutting device 1, while being able to obtain sufficient surface contact on the discharge side of the cutting device 1, so that it is subject to sufficient upper and lower limit effects, so as to provide stability of the strip during the cutting process. For brittle special materials, it can avoid the situation that the material is shifted and deformed due to the vibration and extrusion of the tool during cutting, and then directly produces fracture marks at the incision, resulting in the scrapping of the material, thereby ensuring that the cutting device 1 can effectively perform strip processing on brittle special materials. At the same time, it is also suitable for processing flexible materials and hard materials, and can effectively prevent the above-mentioned strip from being easily shifted, fluctuating or deformed and pulled during the cutting process, thereby affecting the processing accuracy, thereby ensuring the processing accuracy and quality of the strip.

[0041] Therefore, the slitting machine described in the present invention has a simple structure and low cost. It does not need to adjust the parameters such as the tool type, meshing distance, and processing speed of the cutting device 1 every time the material is processed, making the operation more convenient, reducing the workload of workers, and improving production efficiency. When in use, it is only necessary to adjust the clamping device 5 accordingly according to the material type and thickness, so that it can be used for slitting processing of strips of various materials and thicknesses including flexible materials, hard materials, brittle special materials, etc., to ensure the slitting processing accuracy and quality of the strips, improve its versatility, and facilitate the unification of machine models.
