Description

Technical Field

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

[0002] Thin strips refer to relatively thin metal or non-metal strip materials, usually with a certain width and thin thickness. Such materials are often used in the manufacture of various precision parts, electronic products, packaging materials, architectural decoration and other fields. In the production and processing of thin strips, it is often necessary to use a slitting machine to efficiently and accurately cut the wide strip material into multiple narrower strips to meet the needs of different products or processes while minimizing material waste.

[0003] Existing slitting machines, such as a slitting machine for sheet production disclosed in China Publication No. CN216807545U, usually have the following technical problems during use: When cutting thin strips of metal materials, even a slight difference in thickness will affect the cutting stability for hard metal materials, and the existing slitting machines are unable to adjust the cutting speed according to the thickness of the thin strips. When cutting thicker thin strips, the cutting speed cannot be properly increased, resulting in poor cutting effect for thicker thin strips and low slitting efficiency. When cutting thinner thin strips, the cutting speed cannot be properly reduced, resulting in thinner thin strips being more susceptible to mechanical vibrations, tension fluctuations and tool indentations, causing defects such as burrs and deformation on the cut surface of the thin strips, thereby reducing the slitting effect of the thin strips.

[0010] Compared with the existing technology, the advantages of this thin strip sheet slitting machine are: The present invention sets an adjustment mechanism, so that when the thin strip sheet is slit, the annular plate and the transmission teeth on the spline sleeve are at different positions of the conical transmission block. Since the first teeth, the second teeth and the third teeth on the conical transmission block are of different lengths, the number of teeth meshing with the transmission teeth at different positions on the conical transmission block is different, so that when the first motor drives the conical transmission block to rotate, the rotation speed of the rotating rod and the slitting blade is different, and the cutting speed of the thin strip sheet can be adjusted according to its thickness, thereby improving the stability of the thin strip sheet when slitting.

[0011] The present invention sets a transmission mechanism, so that when the thin strip sheet is relatively thick, the transmission teeth are meshed with the first teeth, the second teeth, and the third teeth, so that the rotation speed of the rotating rod and the slitting blade is relatively fast, thereby improving the cutting effect and slitting efficiency of the thicker thin strip sheet; and when the thin strip sheet is relatively thin, the transmission teeth are only meshed with the first teeth with a longer length, so that the rotation speed of the rotating rod and the slitting blade is relatively slow, thereby avoiding defects such as burrs and deformation on the cut surface of the thin strip sheet. In the process of clamping the thin strip sheet, the thickness data of the thin strip sheet can be transmitted to the adjustment mechanism, and the cutting speed of the slitting blade on the thin strip sheet can be automatically adjusted without manual adjustment by the staff.

[0012] The present invention provides a tension control mechanism. When the thickness of the thin strip sheet is relatively thick, the thin strip sheet is relatively unstable. At this time, the piston block is in an outer position in the control groove, so that after the reference plate is released, the compression degree of the third spring is relatively large, so that the tension applied to the thin strip sheet by the third spring and the clamping mechanism on the side plate is relatively large, thereby ensuring the flatness of the thin strip sheet during the stripping process and avoiding relaxation or wrinkling. When the thickness of the thin strip sheet is relatively thin, the reference plate can be ejected a relatively small distance under the elastic force of the second spring after being released, so that the tension applied to the thin strip sheet by the third spring and the clamping mechanism on the side plate is relatively small, thereby avoiding deformation of the thin strip sheet during the cutting process and improving the cutting stability and quality.

DETAILED DESCRIPTION

[0015] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0016] Example: Refer to Figures 1 to 8 , a thin strip sheet material slitting machine, comprising: A processing table 1, 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, a plurality of slitting blades 14 are linearly arrayed on the rotating rod 13, and side plates 15 are symmetrically installed on both sides of the processing table 1; 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. Both of these are existing mature technologies, so they are not described in detail in this application.

[0017] The adjusting mechanism 2 is used to adjust the cutting speed of the slitting blade 14. The adjusting mechanism 2 includes a first motor 21 fixedly connected to the side wall of the U-shaped plate 12. A conical transmission block 22 is fixedly connected to the output end of the first motor 21. A plurality of first teeth 23, second teeth 24 and third teeth 25 distributed in a circumferential array are arranged in a circumferential array on the circumferential side wall of the conical transmission block 22. The lengths of the first teeth 23, second teeth 24 and third teeth 25 distributed in a circumferential array decrease in sequence. The end of the rotating rod 13 close to the first motor 21 passes through A U-shaped plate 12 is provided with a spline groove 26, and a spline sleeve 27 used therewith is sleeved on the spline groove 26. An annular telescopic plate 28 is fixedly connected to one end of the U-shaped plate 12 close to 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 circumferential side wall of the spline sleeve 27. The annular plate 29 is provided with a plurality of slide grooves 210 distributed in a circumferential array. A transmission tooth 211 is slidably connected in the slide groove 210, and a first spring 212 is provided between the transmission tooth 211 and the inner wall of the slide groove 210.

[0018] Specifically, one end of the U-shaped plate 12 close to the annular plate 29 is fixedly connected to the annular baffle 3 through a connecting rod, and a through groove 31 is opened on the side of the annular baffle 3 close to 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, thereby preventing the transmission tooth 211 from always extending out under the elastic force of the first spring 212, resulting in motion interference when it meshes with the first tooth 23, the second tooth 24 and the third tooth 25.

[0019] Specifically, the arrangement of the spline groove 26 and the spline sleeve 27 enables the annular plate 29 and the driving teeth 211 thereon to not only slide along the axial direction of the rotating rod 13, but also to always drive the rotating rod 13 to rotate synchronously when rotating, thereby ensuring that the slitting blade 14 cuts the thin strip of sheet material.

[0020] In view of the problem that even a slight thickness difference in the prior art will affect the cutting stability for hard metal materials, and the existing slitting machine cannot adjust the cutting speed according to the thickness of the thin strip sheet, the present invention sets an adjustment mechanism 2. When the thin strip sheet is slid, the position of the spline sleeve 27 can be adjusted by the annular telescopic plate 28, so that the annular plate 29 and the transmission teeth 211 on the spline sleeve 27 are at different positions of the conical transmission block 22. Since the first teeth 23, the second teeth 24 and the third teeth 25 on the conical transmission block 22 have different lengths, the number of teeth meshing with the transmission teeth 211 is different when it is at different positions on the conical transmission block 22, so that when the first motor 21 drives the conical transmission block 22 to rotate, the rotation speed of the transmission teeth 211 and the spline groove 26 is different, and the rotation speed of the rotating rod 13 and the slitting blade 14 is further different. It can adjust the cutting speed according to the thickness of the thin strip sheet, and improve the stability of the thin strip sheet when slitting.

[0021] 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 screw rod 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 screw rod 42 is provided on the lower wall of the support plate 41 below. Clamping plates 44 are threadedly connected to the threads on both sides of the bidirectional screw rod 42. The clamping plates 44 are slidably connected to the side walls of the side plates 15 in a vertical direction. A plurality of clamping strips 45 in a linear array are fixedly connected to the clamping plates 44. The plurality of clamping strips 45 and the plurality of slitting blades 14 are staggered.

[0022] In the actual processing process, before the thin strip sheet is slit, the bidirectional screw 42 can be driven to rotate by the second motor 43, and the two clamping plates 44 can be further driven to approach each other, so that the clamping strips 45 on the two clamping plates 44 can approach each other, and the thin strip sheet is clamped and fixed. Here, the clamping strips 45 and the slitting blades 14 are staggered, so that the slitting work of the thin strip sheet will not be affected.

[0023] A transmission mechanism 5 controlled by the clamping mechanism 4 is also provided above the processing table 1, which is used for automatically adjusting 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 screw rod 42 extends through the support plate 41 to the interior of the liquid storage cylinder 51, and is coaxially fixedly connected with a threaded rod 52, a piston plate 53 is threadedly connected to the threaded rod 52, and the piston plate 53 is air-tightly slidably connected to the inner wall of the liquid storage cylinder 51 in the vertical direction, a first infusion pipe 54 is connected between the interior of the liquid storage cylinder 51 and the interior of the annular telescopic plate 28, and the interiors of the liquid storage cylinder 51, the annular telescopic plate 28 and the first infusion pipe 54 are all filled with hydraulic oil.

[0024] It is worth mentioning that the present invention sets a transmission mechanism 5. During the clamping process, due to the different thicknesses of the thin strip sheets, after the thin strip sheets are clamped, the bidirectional screw rod 42 drives the threaded rod 52 to rotate to different degrees, further causing the piston plate 53 to be at a different position in the liquid reservoir 51. When the thin strip sheets are relatively thick, the piston plate 53 is located at a lower position inside the liquid reservoir 51, so that the hydraulic oil in the liquid reservoir 51 can be transported to the annular telescopic plate 28, so that the extended length of the annular telescopic plate 28 is relatively long, so that the transmission teeth 211 are meshed with the first teeth 23, the second teeth 24, and the third teeth 25, so that 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, thereby improving the control of the thicker thin strip sheets. The cutting effect and slitting efficiency of thin strip sheets are improved. When the thin strip sheets are relatively thin, the piston plate 53 is located in the upper position inside the liquid storage cylinder 51, so that the hydraulic oil in the annular telescopic plate 28 can be transported to the liquid storage cylinder 51, so that the extended length of the annular telescopic plate 28 is relatively short, so that the transmission teeth 211 only mesh with the first teeth 23 with a longer length, and then 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 burrs, deformation and other defects on the cutting surface of the thin strip sheets. In the process of clamping the thin strip sheets, the thickness data of the thin strip sheets can be transmitted to the adjusting mechanism 2, and the cutting speed of the slitting blade 14 for the thin strip sheets can be adjusted automatically without manual adjustment by the staff. The operation is convenient and the work efficiency is improved.

[0025] A tension control mechanism 6 controlled by the clamping mechanism 4 is also provided below the processing table 1. The tension control mechanism 6 includes a control box 61 fixedly connected to the lower end of the processing table 1. Two control grooves 62 are symmetrically provided on both sides of the control box 61. A piston block 63 is airtightly slidably connected in the control groove 62 in the horizontal direction. A reference plate 64 is slidably connected to the lower end of the processing table 1 in the horizontal direction. A second spring 65 is provided between the piston block 63 and the reference plate 64. An empty groove 66 is provided on the processing table 1. The side plate 15 is slidably connected to the inner wall of the empty groove 66 in the horizontal direction. The side plate 15 extends through the empty groove 66 to the bottom of the processing table 1, and a third spring 67 is provided between the side plate 15 and the reference plate 64. Both clamping plates 44 pass through the side plates 15 and A first hinge seat 68 is fixedly connected, and a liquid storage tank 69 is fixedly connected to a side wall of the side plate 15 away from the bidirectional screw rod 42. A sealing plate 610 is air-tightly and 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. Second hinge seats 613 are 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 first hinge seat 68 at the corresponding position. A second infusion pipe 615 is connected between the liquid storage tank 69 and the inside of the control groove 62 on the corresponding side. The liquid storage tank 69, the control groove 62 and the second infusion pipe 615 are filled with hydraulic oil.

[0026] In the slitting process, since the slitting blade 14 adjusts its cutting speed according to the thickness of the thin strip sheet, when the cutting speed of the slitting blade 14 is relatively fast, the thin strip sheet is relatively unstable. At this time, if the tension cannot be properly increased, the tension of the thin strip sheet will be insufficient, causing the thin strip sheet to be unable to remain flat, and to become loose or wrinkled, which not only affects the cutting stability, but may also cause the slitting blade to get stuck or the thin strip sheet to be delayed, affecting the production process. When the cutting speed of the slitting blade 14 is relatively slow, the thin strip sheet is relatively stable. At this time, if the tension cannot be properly reduced, the tension of the thin strip sheet will be too large, causing the thin strip sheet to deform or even be torn during the cutting process, affecting the cutting stability and quality; Based on the above problems, the present invention sets a tension control mechanism 6. In the process of clamping the thin strip sheet, the two clamping plates 44 approach each other, and the moving block 612 is driven to move through the first hinge seat 68, the second hinge seat 613 and the connecting rod 614, and the sealing plate 610 is further driven to move in the liquid storage tank 69 through the push rod 611. When the thickness of the thin strip sheet is relatively thick, the cutting speed of the slitting blade 14 is relatively fast, and the thin strip sheet is relatively unstable. At this time, the sealing plate 610 can transport the hydraulic oil in the liquid storage tank 69 to the control groove 62 through the second liquid delivery pipe 615, so that the piston block 63 is located in the outer position of the control groove 62, and then the reference plate 64 can be released. The distance is relatively large under the elastic force of the second spring 65, and the degree of compression of the third spring 67 by the reference plate 64 is further large. According to the spring formula: F=kx, where x is the degree of compression of the spring, it can be known that the elastic force of the third spring 67 is proportional to its degree of compression. Therefore, the tension applied to the thin strip sheet 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 sheet during the slitting process and avoiding relaxation or wrinkling. When the thickness of the thin strip sheet is relatively thin, the sealing plate 610 can transport the hydraulic oil in the control groove 62 to the liquid storage tank 69 through the second infusion pipe 615, so that the piston block 63 is in the inner position of the control groove 62, and then the reference plate 64 can be released. The elastic force of the second spring 65 can pop out a relatively small distance, so that the degree of compression of the third spring 67 by the reference plate 64 is relatively small, so that the tension applied to the thin strip sheet by the third spring 67 and the clamping mechanism 4 on the side plate 15 is relatively small, thereby avoiding deformation of the thin strip sheet during the cutting process and improving the stability and quality of the cutting.

[0027] Specifically, the elastic force of the second spring 65 is greater than the elastic force 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 will not be adjusted immediately during the clamping process, but the tension will be adjusted after the clamping is completed to avoid affecting the clamping work.

[0028] Specifically, a receiving groove 7 is provided on the lower wall of the processing table 1, and a wedge-shaped block 71 is slidably connected to the inner wall of the receiving groove 7. A slot 72 used in conjunction with the wedge-shaped block 71 is provided on the upper wall of the reference plate 64. During the clamping process, the wedge-shaped block 71 can automatically fall into the slot 72 under the action of gravity, thereby locking the position of the reference plate 64.

[0029] Specifically, an electromagnet 8 is provided on the side where the wedge-shaped block 71 and the storage slot 7 are close to each other. When the two electromagnets 8 are energized, the opposite poles attract each other. A touch pressure switch 81 and a pressure sensor 82 are provided at the lower end of one of the clamping bars 45. The touch pressure switch 81 is used to control the shutdown of the second motor 43, and the pressure sensor 82 is used to control the opening of the electromagnet 8.

[0030] In addition, before the thin strip is stripped, the second motor 43 is used to clamp the thin strip. After the clamping is completed, the touch switch 81 is squeezed by the thin strip. At this time, the second motor 43 is turned off, and the two clamping plates 44 are no longer close to each other. At the same time, the pressure sensor 82 is tightly squeezed on the thin strip. The pressure sensor 82 transmits the received pressure data to the control system. When the pressure sensor 82 detects that the pressure data reaches the preset value, the clamping plate 44 completes the clamping of the thin strip, and the second motor 43 is turned off under the action of the touch switch. Turning on the electromagnet 8 will cause the wedge-shaped block 71 to move out of the card slot 72 under the action of magnetic attraction, so that the reference plate 64 can pop out under the elastic force of the second spring 65, and tension is applied to the thin strip, so that the clamping work and tension application work of the thin strip are carried out continuously, and the application of tension is always carried out after the thin strip clamping is completed. The degree of automation is high, which greatly improves the work efficiency.

[0031] The present invention can be explained by the following operation mode: The bidirectional screw rod 42 is driven to rotate by the second motor 43, and the two clamping plates 44 are further driven to approach each other, so that the clamping strips 45 on the two clamping plates 44 can approach each other, and the thin strip sheet is clamped and fixed; During the clamping process, due to the different thicknesses of the thin strips, the bidirectional screw 42 drives the threaded rod 52 to rotate to different degrees, which further causes the position of the piston plate 53 in the liquid storage cylinder 51 to be different. When the thin strip is relatively thick, the piston plate 53 is located at a lower position inside the liquid storage cylinder 51, so that the length of the annular telescopic plate 28 extending is relatively long, so that the transmission teeth 211 are meshed 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 at an upper position inside the liquid storage cylinder 51, so that the rotation speed of the rotating rod 13 and the slitting blade 14 is relatively slow. During the clamping process, the thickness data of the thin strip can be transmitted to the adjustment mechanism 2, and the cutting speed of the slitting blade 14 on the thin strip can be adjusted automatically. At the same time, during the clamping process, the mutual proximity of the two clamping plates 44 will also adjust the tension applied to the thin strip sheet. When the thickness of the thin strip sheet is relatively thick, the piston block 63 is located in the outer position of the control groove 62, so that after the reference plate 64 is released, the compression degree of the third spring 67 is relatively large, so that the tension applied to the thin strip sheet 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 sheet is relatively thin, the piston block 63 is located in the inner position of the control groove 62, so that after the reference plate 64 is released, the compression degree of the third spring 67 is relatively small, so that the tension applied to the thin strip sheet is relatively small.

[0032] 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 principle of the present invention should be included in the protection scope of the present invention.
