Description

Technical Field

[0001] This invention belongs to the field of slitting equipment technology, and in particular relates to a thin strip sheet slitting machine. Background Technology

[0002] Thin strips refer to relatively thin strips of metal or non-metal, typically with a certain width and thickness. These materials are commonly used in the manufacture of various precision components, electronic products, packaging materials, and architectural decoration. In the production and processing of thin strips, slitting machines are often used to efficiently and precisely cut wide strips into multiple narrower strips to meet the needs of different products or processes, while minimizing material waste.

[0003] Existing slitting machines, such as the sheet production slitting machine disclosed in Chinese Publication No. CN216807545U, typically have the following technical problems during use:

[0004] When cutting thin strips of metal, even slight differences in thickness can affect the cutting stability of hard metals. Existing slitting machines cannot adjust the cutting speed according to the thickness of the strip. When cutting thicker strips, the cutting speed cannot be increased appropriately, resulting in poor cutting results and low slitting efficiency. Conversely, when cutting thinner strips, the cutting speed cannot be reduced appropriately, making the thinner strips more susceptible to mechanical vibration, tension fluctuations, and tool indentations. This can cause defects such as burrs and deformation on the cut surface, further reducing the slitting effect of the strips. Summary of the Invention

[0005] The purpose of this invention is to address the problems mentioned in the background art by providing a thin strip slitting machine that can adjust the cutting speed according to the thickness of the thin strip, thereby improving the stability of the thin strip during slitting.

[0006] To achieve the above objectives, the present invention adopts the following technical solutions:

[0007] A thin strip sheet slitting machine, comprising:

[0008] A processing table, wherein a support rod is slidably connected to the top of the processing table in the horizontal direction, a U-shaped plate is slidably connected to the support rod in the vertical direction, a rotating rod is rotatably connected inside the U-shaped plate, and multiple slitting blades are linearly arrayed on the rotating rod, and side plates are symmetrically installed on both sides of the processing table;

[0009] An adjustment mechanism is used to adjust the cutting speed of the slitting blade. The adjustment mechanism includes a first motor fixedly connected to the side wall of a U-shaped plate. A conical transmission block is fixedly connected to the output end of the first motor. The conical transmission block has a plurality of first, second, and third teeth arranged in a circumferential array on its peripheral side wall, and the lengths of the plurality of first, second, and third teeth arranged in a circumferential array decrease sequentially. The end of the rotating rod near the first motor passes through the U-shaped plate and is provided with a spline groove. A spline sleeve is fitted on the spline groove for use. An annular telescopic plate is fixedly connected to the end of the U-shaped plate near the first motor. The telescopic end of the annular telescopic plate is fixedly connected to the spline sleeve. An annular plate is fixedly connected to the peripheral side wall of the spline sleeve. A plurality of circumferentially arranged sliding grooves are opened on the annular plate. Transmission teeth are slidably connected in the sliding grooves. A first spring is provided between the transmission teeth and the inner wall of the sliding groove.

[0010] Preferably, the end of the U-shaped plate near the annular plate is fixedly connected to an annular baffle by a connecting rod. The annular baffle has a through groove on the side near the conical transmission block. The transmission teeth pass through the through groove and mesh with the first tooth, the second tooth, and the third tooth.

[0011] Preferably, the side plate is provided with a clamping mechanism for clamping and fixing the thin strip sheet. The clamping mechanism includes two support plates fixedly connected to the side plate. A bidirectional lead screw with threads on both sides and opposite spiral directions is rotatably connected between the two support plates. A second motor for driving the bidirectional lead screw is provided on the lower wall of the lower support plate. Clamping plates are threaded to the threads on both sides of the bidirectional lead screw. The clamping plates are slidably connected to the side wall of the side plate in the vertical direction. Multiple clamping bars arranged in a linear array are fixedly connected to the clamping plates. The multiple clamping bars and multiple slitting blades are staggered.

[0012] Preferably, a transmission mechanism controlled by a clamping mechanism is provided above the processing table for automatically adjusting the cutting speed of the slitting blade according to its thickness when clamping the thin strip sheet. The transmission mechanism includes a liquid storage cylinder fixedly connected to the side plate. The bidirectional lead screw extends through the support plate into the interior of the liquid storage cylinder and is coaxially fixedly connected to a threaded rod. A piston plate is threadedly connected to the threaded rod. The piston plate is airtightly slidably connected to the inner wall of the liquid storage cylinder in the vertical direction. A first liquid delivery pipe is connected between the interior of the liquid storage cylinder and the interior of the annular telescopic plate. The interior of the liquid storage cylinder, the annular telescopic plate, and the first liquid delivery pipe are all filled with hydraulic oil.

[0013] Preferably, a tension control mechanism controlled by a clamping mechanism is further provided below the processing table. The tension control mechanism includes a control box fixedly connected to the lower end of the processing table. Two control slots are symmetrically opened on both sides of the control box. A piston block is airtightly slidably connected in the horizontal direction within the control slot. A reference plate is slidably connected in the horizontal direction at the lower end of the processing table. A second spring is provided between the piston block and the reference plate. A slot is opened on the processing table. A side plate is slidably connected in the horizontal direction to the inner wall of the slot. The side plate extends through the slot to the lower part of the processing table and is provided with a third spring between it and the reference plate. The clamping plates all pass through the side plates and are fixedly connected to the first hinge seats. A liquid storage tank is fixedly connected to the side wall of the side plate away from the bidirectional lead screw. A sealing plate is airtightly slidably connected inside the liquid storage tank. A push rod is fixedly connected to the sealing plate. The push rod extends to the outside of the liquid storage tank and is fixedly connected to a moving block. A second hinge seat is fixedly connected to the upper and lower side walls of the moving block. A connecting rod is hinged between the second hinge seat and the corresponding first hinge seat. A second infusion pipe is connected between the liquid storage tank and the control tank on the corresponding side. The liquid storage tank, the control tank, and the second infusion pipe are all filled with hydraulic oil.

[0014] Compared with existing technologies, the advantages of this thin strip sheet slitting machine are:

[0015] This invention, by setting an adjustment mechanism, ensures that the annular plate and transmission teeth on the spline sleeve are positioned at different locations on the conical transmission block during the slitting of thin strips. Since the lengths of the first, second, and third teeth on the conical transmission block are different, the number of teeth meshing with the transmission teeth varies depending on their position on the conical transmission block. This results in different rotational speeds of the rotating rod and slitting blade when the first motor drives the conical transmission block to rotate. This allows for adjustment of the cutting speed according to the thickness of the thin strip, improving the stability of the slitting process.

[0016] This invention, through the design of a transmission mechanism, ensures that when the thin strip is relatively thick, the transmission teeth engage with the first, second, and third teeth, resulting in a relatively fast rotation speed of the rotating rod and slitting blade. This improves the cutting effect and slitting efficiency for thicker thin strips. Conversely, when the thin strip is relatively thin, the transmission teeth engage only with the longer first tooth, resulting in a relatively slow rotation speed of the rotating rod and slitting blade. This avoids defects such as burrs and deformation on the cut surface of the thin strip. Furthermore, during the clamping process, the thickness data of the thin strip is transmitted to the adjustment mechanism, which automatically adjusts the cutting speed of the slitting blade without requiring manual adjustment by the operator.

[0017] This invention, through the setting of a tension control mechanism, addresses the issue that when the thickness of the thin strip is relatively thick, the strip is relatively unstable. In this case, the piston block is positioned near the outer edge of the control groove, resulting in a relatively large compression of the third spring after the reference plate is released. This leads to a relatively large tension applied to the thin strip by the third spring and the clamping mechanism on the side plate, ensuring the flatness of the thin strip during the slitting process and preventing loosening or wrinkling. Conversely, when the thickness of the thin strip is relatively thin, the reference plate can spring out a relatively small distance under the elastic force of the second spring after release. This results in a relatively small tension applied to the thin strip by the third spring and the clamping mechanism on the side plate, preventing deformation of the thin strip during cutting and improving the stability and quality of the cutting process.

Detailed Implementation

[0027] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0028] Example: Refer to Figures 1 to 8 A thin strip sheet slitting machine, comprising:

[0029] A processing table 1 is provided. A support rod 11 is slidably connected to the top of the processing table 1 in the horizontal direction. A U-shaped plate 12 is slidably connected to the support rod 11 in the vertical direction. A rotating rod 13 is rotatably connected inside the U-shaped plate 12. Multiple slitting blades 14 are linearly arrayed on the rotating rod 13. Side plates 15 are symmetrically installed on both sides of the processing table 1.

[0030] Specifically, the horizontal sliding of the support rod 11 can be driven by a lead screw and a motor, while the vertical sliding of the U-shaped plate 12 can be driven by an electric telescopic rod. These are all existing mature technologies, so they are not described in detail in this application.

[0031] Adjustment mechanism 2 is used to adjust the cutting speed of slitting blade 14. Adjustment mechanism 2 includes a first motor 21 fixedly connected to the side wall of U-shaped plate 12. A conical transmission block 22 is fixedly connected to the output end of the first motor 21. The conical transmission block 22 has a plurality of first teeth 23, second teeth 24 and third teeth 25 arranged in a circumferential array on its peripheral side wall. The lengths of the plurality of first teeth 23, second teeth 24 and third teeth 25 arranged in a circumferential array decrease sequentially. The end of the rotating rod 13 near the first motor 21 passes through... A U-shaped plate 12 is provided with a spline groove 26. A spline sleeve 27 is fitted on the spline groove 26 for use with it. An annular telescopic plate 28 is fixedly connected to one end of the U-shaped plate 12 near the first motor 21. The telescopic end of the annular telescopic plate 28 is fixedly connected to the spline sleeve 27. An annular plate 29 is fixedly connected to the peripheral side wall of the spline sleeve 27. Multiple circularly arranged sliding grooves 210 are provided on the annular plate 29. Transmission teeth 211 are slidably connected in the sliding grooves 210. A first spring 212 is provided between the transmission teeth 211 and the inner wall of the sliding grooves 210.

[0032] Specifically, one end of the U-shaped plate 12 near the annular plate 29 is fixedly connected to an annular baffle 3 via a connecting rod. The annular baffle 3 has a through groove 31 on one side near the conical transmission block 22. The transmission tooth 211 passes through the through groove 31 and meshes with the first tooth 23, the second tooth 24, and the third tooth 25. Through the annular baffle 3 and the through groove 31, the transmission tooth 211 can only extend to the outside of the annular baffle 3 through the through groove 31 and mesh with the first tooth 23, the second tooth 24, and the third tooth 25 on the conical transmission block 22. This prevents the transmission tooth 211 from always extending under the elastic force of the first spring 212, which would cause motion interference when it meshes with the first tooth 23, the second tooth 24, and the third tooth 25.

[0033] Specifically, the spline groove 26 and spline sleeve 27 are designed so that the annular plate 29 and its transmission teeth 211 can not only slide along the axial direction of the rotating rod 13, but also drive the rotating rod 13 to rotate synchronously during rotation, ensuring that the slitting blade 14 cuts the thin strip.

[0034] To address the problem that even minute thickness differences in existing technologies can affect the cutting stability of hard metal materials, and that existing slitting machines cannot adjust the cutting speed according to the thickness of thin strips, this invention addresses this issue by setting an adjustment mechanism 2. During the slitting of thin strips, the position of the spline sleeve 27 can be adjusted via the annular telescopic plate 28. This allows the annular plate 29 and the transmission teeth 211 on the spline sleeve 27 to be positioned at different locations on the conical transmission block 22. Since the first tooth 23, the second tooth 24, and the third tooth 25 on the conical transmission block 22 have different lengths, the number of teeth meshing with the transmission teeth 211 varies depending on its position on the conical transmission block 22. Consequently, when the first motor 21 drives the conical transmission block 22, the rotation speed of the transmission teeth 211 and the spline groove 26 varies, further resulting in different rotation speeds for the rotating rod 13 and the slitting blade 14. This allows for adjustment of the cutting speed according to the thickness of the thin strip, improving the stability of the thin strip slitting process.

[0035] A clamping mechanism 4 is provided on the side plate 15 for clamping and fixing the thin strip sheet. The clamping mechanism 4 includes two support plates 41 fixedly connected to the side plate 15. A bidirectional lead screw 42 with threads on both sides and opposite spiral directions is rotatably connected between the two support plates 41. A second motor 43 for driving the bidirectional lead screw 42 is provided on the lower wall of the lower support plate 41. Clamping plates 44 are threaded to the threads on both sides of the bidirectional lead screw 42. The clamping plates 44 are slidably connected to the side wall of the side plate 15 in the vertical direction. Multiple clamping bars 45 arranged in a linear array are fixedly connected to the clamping plates 44. The multiple clamping bars 45 and multiple slitting blades 14 are staggered.

[0036] In the actual processing, before slitting the thin strip, the second motor 43 can drive the bidirectional lead screw 42 to rotate, which in turn drives the two clamping plates 44 to move closer to each other, so that the clamping strips 45 on the two clamping plates 44 can move closer to each other and clamp and fix the thin strip. Here, the clamping strips 45 and the slitting blade 14 are staggered, so they will not affect the slitting of the thin strip.

[0037] Above the processing table 1 is a transmission mechanism 5 controlled by the clamping mechanism 4, which is used to automatically adjust the cutting speed of the slitting blade 14 according to its thickness when clamping the thin strip sheet. The transmission mechanism 5 includes a liquid storage cylinder 51 fixedly connected to the side plate 15, a bidirectional lead screw 42 extending through the support plate 41 into the interior of the liquid storage cylinder 51, and a threaded rod 52 fixedly connected coaxially. A piston plate 53 is threadedly connected to the threaded rod 52. The piston plate 53 is airtightly slidably connected to the inner wall of the liquid storage cylinder 51 in the vertical direction. A first liquid delivery pipe 54 is connected between the interior of the liquid storage cylinder 51 and the interior of the annular telescopic plate 28. The interiors of the liquid storage cylinder 51, the annular telescopic plate 28 and the first liquid delivery pipe 54 are all filled with hydraulic oil.

[0038] It is worth mentioning that, by setting up the transmission mechanism 5, during the clamping process, due to the different thicknesses of the thin strip sheet, the rotation degree of the bidirectional lead screw 42 driving the threaded rod 52 is different after the thin strip sheet is clamped. This further causes the piston plate 53 to be positioned differently inside the liquid storage cylinder 51. When the thin strip sheet is relatively thick, the piston plate 53 is positioned lower inside the liquid storage cylinder 51, thereby allowing the hydraulic oil in the liquid storage cylinder 51 to be transported to the annular telescopic plate 28. This results in a relatively longer extension length of the annular telescopic plate 28, allowing the transmission teeth 211 to mesh with the first tooth 23, the second tooth 24, and the third tooth 25. Consequently, when the first motor 21 drives the conical transmission block 22 to rotate, the rotation speed of the rotating rod 13 and the slitting blade 14 is relatively fast, improving the handling of thicker strip sheets. The cutting effect and slitting efficiency of thin strip sheets are improved. When the thin strip sheet is relatively thin, the piston plate 53 is positioned at the upper part of the liquid storage cylinder 51, so that the hydraulic oil in the annular telescopic plate 28 can be transported into the liquid storage cylinder 51. This results in a relatively short extension length of the annular telescopic plate 28, so that the transmission teeth 211 only mesh with the longer first teeth 23. Consequently, when the first motor 21 drives the conical transmission block 22 to rotate, the rotation speed of the rotating rod 13 and the slitting blade 14 is relatively slow, avoiding defects such as burrs and deformation on the cut surface of the thin strip sheet. During the clamping process of the thin strip sheet, the thickness data of the thin strip sheet can be transmitted to the adjustment mechanism 2, which automatically adjusts the cutting speed of the slitting blade 14 on the thin strip sheet without the need for manual adjustment by the operator, making the operation convenient and improving work efficiency.

[0039] Below the processing table 1, there is also a tension control mechanism 6 controlled by the clamping mechanism 4. The tension control mechanism 6 includes a control box 61 fixedly connected to the lower end of the processing table 1. Two control slots 62 are symmetrically opened on both sides of the control box 61. A piston block 63 is airtightly slidably connected in the horizontal direction in the control slot 62. A reference plate 64 is slidably connected in the horizontal direction at the lower end of the processing table 1. A second spring 65 is provided between the piston block 63 and the reference plate 64. A slot 66 is opened on the processing table 1. A side plate 15 is slidably connected in the horizontal direction to the inner wall of the slot 66. The side plate 15 extends through the slot 66 to the lower part of the processing table 1, and a third spring 67 is provided between it and the reference plate 64. Both clamping plates 44 pass through the side plate 15 and A first hinge seat 68 is fixedly connected. A liquid storage tank 69 is fixedly connected to the side wall of the side plate 15 away from the bidirectional lead screw 42. A sealing plate 610 is airtightly slidably connected inside the liquid storage tank 69. A push rod 611 is fixedly connected to the sealing plate 610. The push rod 611 extends to the outside of the liquid storage tank 69 and is fixedly connected to a moving block 612. A second hinge seat 613 is fixedly connected to the upper and lower side walls of the moving block 612. A connecting rod 614 is hinged between the second hinge seat 613 and the corresponding first hinge seat 68. A second infusion pipe 615 is connected between the liquid storage tank 69 and the control tank 62 on the corresponding side. The liquid storage tank 69, the control tank 62 and the second infusion pipe 615 are all filled with hydraulic oil.

[0040] During the slitting process, the slitting blade 14 adjusts its cutting speed according to the thickness of the thin strip. When the cutting speed of the slitting blade 14 is relatively fast, the thin strip is relatively unstable. If the tension cannot be increased appropriately, the tension of the thin strip will be insufficient, causing the thin strip to be unable to remain flat, resulting in loosening or wrinkling. This not only affects the stability of the cutting but may also cause the slitting blade to jam or the thin strip to be delayed, affecting the production process. When the cutting speed of the slitting blade 14 is relatively slow, the thin strip is relatively stable. If the tension cannot be decreased appropriately, the tension of the thin strip will be too high, causing the thin strip to deform or even tear during the cutting process, affecting the stability and quality of the cutting.

[0041] Based on the above problems, the present invention sets up a tension control mechanism 6. During the clamping process of the thin strip sheet, the two clamping plates 44 approach each other, and the moving block 612 will be moved through the first hinge seat 68, the second hinge seat 613 and the connecting rod 614. Furthermore, the sealing plate 610 will be moved in the liquid storage tank 69 through the push rod 611.

[0042] When the thickness of the thin strip is relatively thick, the cutting speed of the slitting blade 14 is relatively fast, and the thin strip is relatively unstable. At this time, the sealing plate 610 can transport the hydraulic oil in the reservoir 69 to the control groove 62 through the second inlet pipe 615, so that the piston block 63 is in the outer position in the control groove 62. As a result, after the reference plate 64 is released, it can be ejected a relatively large distance under the elastic force of the second spring 65. This further makes the compression of the reference plate 64 on the third spring 67 relatively large. According to the spring formula: F=kx, where x is the degree of spring compression, it can be seen that the elastic force of the third spring 67 is proportional to its degree of compression. Therefore, the tension applied to the thin strip by the third spring 67 and the clamping mechanism 4 on the side plate 15 is relatively large, ensuring the flatness of the thin strip during the slitting process and avoiding loosening or wrinkling.

[0043] When the thickness of the thin strip is relatively thin, the sealing plate 610 can transport the hydraulic oil in the control groove 62 to the storage tank 69 through the second inlet pipe 615, so that the piston block 63 is in the inner position in the control groove 62. As a result, after the reference plate 64 is released, it can pop out a relatively small distance under the elastic force of the second spring 65, so that the compression of the reference plate 64 on the third spring 67 is relatively small. Therefore, the tension applied to the thin strip by the third spring 67 and the clamping mechanism 4 on the side plate 15 is relatively small, which avoids the thin strip from deforming during the cutting process and improves the stability and quality of the cutting.

[0044] Specifically, the elastic force of the second spring 65 is greater than that of the third spring 67. The elastic force of the second spring 65 is used to adjust the position of the reference plate 64, thereby adjusting the compression degree of the third spring 67 by changing the position of the reference plate 64. The setting of the second spring 65 ensures that the tension is not adjusted immediately during the clamping process, but only after the clamping is completed, so as to avoid affecting the clamping operation.

[0045] Specifically, the lower wall of the processing table 1 is provided with a storage groove 7, and a wedge-shaped locking block 71 is slidably connected to the inner wall of the storage groove 7. The upper wall of the reference plate 64 is provided with a slot 72 that cooperates with the wedge-shaped locking block 71. During the clamping process, the wedge-shaped locking block 71 can automatically fall into the slot 72 under the action of gravity, thereby locking the position of the reference plate 64.

[0046] Specifically, electromagnets 8 are provided on the sides of the wedge-shaped block 71 and the storage slot 7 that are close to each other. When the two electromagnets 8 are energized, opposite poles attract each other. A touch switch 81 and a pressure sensor 82 are provided at the lower end of one of the clamping bars 45. The touch switch 81 is used to control the closing of the second motor 43, and the pressure sensor 82 is used to control the opening of the electromagnet 8.

[0047] In addition, before the thin strip is slitting, the second motor 43 clamps the thin strip. After clamping, the touch switch 81 is squeezed by the thin strip, at which point the second motor 43 is turned off, and the two clamping plates 44 no longer approach each other. At the same time, the pressure sensor 82 is pressed tightly onto the thin strip, and the pressure sensor 82 transmits the received pressure data to the control system. When the pressure sensor 82 detects that the pressure data has reached the preset value, the clamping plate 44 completes the clamping of the thin strip. The second motor 43 is turned off by the touch switch, and the electromagnet 8 is turned on, causing the wedge-shaped block 71 to move out of the slot 72 under the action of magnetic attraction. This allows the reference plate 64 to pop out under the action of the second spring 65, applying tension to the thin strip. Thus, the clamping and tension application of the thin strip are carried out continuously, and the tension application always occurs after the thin strip is clamped. This high degree of automation greatly improves work efficiency.

[0048] The functional principle of this invention can be explained through the following operational methods:

[0049] The second motor 43 drives the bidirectional lead screw 42 to rotate, which further drives the two clamping plates 44 to move closer to each other, so that the clamping strips 45 on the two clamping plates 44 can move closer to each other to clamp and fix the thin strip sheet.

[0050] During the clamping process, due to the different thicknesses of the thin strip, the rotation degree of the threaded rod 52 driven by the bidirectional lead screw 42 is different, which further causes the piston plate 53 to be in different positions inside the liquid storage cylinder 51. When the thin strip is relatively thick, the piston plate 53 is located in the lower position inside the liquid storage cylinder 51, which makes the length of the annular telescopic plate 28 extended relatively long, so that the transmission teeth 211 mesh with the first teeth 23, the second teeth 24, and the third teeth 25, thereby making the rotation speed of the rotating rod 13 and the slitting blade 14 relatively fast. When the thin strip is relatively thin, the piston plate 53 is located in the upper position inside the liquid storage cylinder 51, which makes the rotation speed of the rotating rod 13 and the slitting blade 14 relatively slow. During the clamping process, the thickness data of the thin strip can be transmitted to the adjustment mechanism 2, which can adjust the cutting speed of the slitting blade 14 on the thin strip.

[0051] Meanwhile, the approach of the two clamping plates 44 during clamping will also adjust the tension applied to the thin strip. When the thickness of the thin strip is relatively thick, the piston block 63 is in the outer position inside the control groove 62, which makes the compression of the third spring 67 after the reference plate 64 is released relatively large, so that the tension applied to the thin strip by the third spring 67 and the clamping mechanism 4 on the side plate 15 is relatively large. When the thickness of the thin strip is relatively thin, the piston block 63 is in the inner position inside the control groove 62, which makes the compression of the third spring 67 after the reference plate 64 is released relatively small, so that the tension applied to the thin strip is relatively small.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
