[0034] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0035] Please see Figure 1-16The present invention provides a technical solution including a frame 1 and a controller installed on one side of the frame 1. A conveying mechanism 2 is provided on one side of the frame 1, a feeding roller 3 is provided in the middle of the frame 1, and a tensioning mechanism 4 is provided below the frame 1. The tensioning mechanism 4 is located on the side below the feeding roller 3. The tensioning mechanism 4 includes a tensioning roller 401 fixedly connected to the frame 1. The tensioning roller 401 has four sets of placement slots 402 inside. Each of the four sets of placement slots 402 is equipped with a cylinder 403. The output end of the cylinder 403 is fixedly connected to a tensioning block 404. A pressure sensor 405 is provided inside the tensioning block 404.
[0036] The controller is electrically connected to the cylinder 403. The controller remotely controls the extension of the cylinder 403, which in turn pushes the tension block 404 away from the tension roller 401, allowing it to contact the material surface and apply pressure to stretch and tighten it. This stretches and tightens the material, which was originally wrinkled or loose, achieving flat tension and ensuring that the material remains flat during subsequent slitting. At the same time, there are four sets of tension blocks 404, and each set of tension blocks 404 is equipped with a pressure sensor 405. The tension can be partially adjusted according to different states during the rubber conveying process. When the applied pressure is too high, the controller can control the cylinder 403 to contract, thereby reducing the applied pressure and preventing the material from being damaged due to improper tension.
[0037] It should be added that the material is rubber sheet.
[0038] like Figure 1 , Figure 2 , Figure 4 , Figure 6 as well as Figure 7 As shown, a first dust cleaning mechanism 5 and a second dust cleaning mechanism 7 are provided on one side of the tensioning block 404. The first dust cleaning mechanism 5 includes a first fixing block 501 fixedly connected to one side of the tensioning block 404. Electric telescopic rods 6 are installed on both sides of the tensioning roller 401. The second dust cleaning mechanism 7 includes a second fixing block 701 connected to the output end of the electric telescopic rod 6. The first dust cleaning mechanism 5 is located below the second dust cleaning mechanism 7. A brush 502 is provided on one side of both the first fixing block 501 and the second fixing block 701.
[0039] The first dust cleaning mechanism 5 is fixedly connected to the tensioning block 404 via the first fixing block 501 and can operate synchronously with the tensioning block 404. The second dust cleaning mechanism 7 is located directly above the first dust cleaning mechanism 5. The two are connected by an electric telescopic rod 6. When the electric telescopic rod 6 extends or retracts, the distance between the two cleaning mechanisms can be adjusted so that the upper and lower brushes 502 can fit against the material surface. This ensures that impurities are cleaned while avoiding excessive squeezing that could damage the material.
[0040] like Figure 3 as well as Figure 4 As shown, a first vision sensor 506 is installed on the side of the first fixing block 501 and the second fixing block 701 away from the tensioning block 404. A dust concentration sensor 26 is installed on one side of the first vision sensor 506. A support frame 507 is provided on the side of the tensioning block 404 away from the first dust cleaning mechanism 5. A second vision sensor 508 is provided below the support frame 507.
[0041] It should be noted that the dust concentration sensor 26 is existing technology and will not be discussed further here.
[0042] The first vision sensor 506 can detect the initial state of the rubber surface before tensioning during the conveying process, while the second vision sensor 508 can detect the state of the rubber surface after tensioning.
[0043] like Figure 2 , Figure 7 as well as Figure 9 As shown, the first fixing block 501 of the first dust cleaning mechanism 5 is fixedly connected to the limiting rod 8, and the second fixing block 701 of the second dust cleaning mechanism 7 is fixedly connected to the limiting sleeve 9. The limiting rod 8 and the limiting sleeve 9 are slidably connected.
[0044] When the electric telescopic rod 6 pushes the second dust cleaning mechanism 7 to move up and down, the limiting sleeve 9 at the second fixed block 701 can slide up and down along the limiting rod 8 to ensure stability during the movement.
[0045] like Figure 1 , Figure 7 , Figure 9 , Figure 10 as well as Figure 11 As shown, both the first fixing block 501 and the second fixing block 701 have a hollow cavity 503 inside. Multiple sets of suction pipes 504 are provided on the side of both the first fixing block 501 and the second fixing block 701 near the brush 502. Each set of the first fixing block 501 and the second fixing block 701 has four sets. Connecting pipes 505 connect adjacent sets of the first fixing blocks 501 and adjacent sets of the second fixing blocks 701. The bottom end of the suction pipe 504 is connected to the hollow cavity 503, and the connecting pipe 505 is also connected to the hollow cavity 503. The second fixing blocks 701 of the two adjacent groups are fixedly connected by mounting blocks. A dust collection assembly 10 is provided on one side of the frame 1. The dust collection assembly 10 includes a dust collection box 1001 fixedly installed on the outer surface of one side of the frame 1. A negative pressure fan 1002 is installed inside the dust collection box 1001. An air outlet 1003 is opened on one side of the dust collection box 1001. One end of a central pipe 1004 is connected to the other side of the dust collection box 1001. The connecting pipes 505 at the first fixing blocks 501 and the second fixing blocks 701 at both ends are fixedly connected to the central pipe 1004.
[0046] The controller is electrically connected to the negative pressure fan 1002. When the controller drives the negative pressure fan 1002 in the dust collection assembly 10 to start working, one end of the central pipe 1004 is connected to the dust collection box 1001, and the other end is connected to the hollow cavity 503. The negative pressure fan 1002 generates suction force through high-speed rotation. When the rubber is being transported, the brush 502 generates friction with the rubber surface, which can clean the impurities on the rubber surface. The cleaned impurities enter the hollow cavity 503 through the dust collection pipe 504. The dust and impurities in the hollow cavity 503 enter the central pipe 1004 through the connecting pipe 505 and finally enter the dust collection box 1001. A filter screen is installed at the air outlet 1003 of the dust collection box 1001 so that when the air is discharged, it can intercept the dust and impurities in the air and keep them in the dust collection box 1001.
[0047] like Figure 1 , Figure 12 as well as Figure 15 As shown, a support rod 11 is fixedly connected to the middle of the frame 1, and a fixed sleeve 12 is rotatably connected to the outer surface of the support rod 11. A rotating shaft 13 is connected to one side of the fixed sleeve 12 by a bearing. A fixed rod 14 is fixedly connected to one side of the rotating shaft 13. A cutter 15 is connected to one end of the fixed rod 14. The cutter 15 is located on one side below the cleaning device.
[0048] The fixing rod 14 at the cutter 15 is connected to the fixing sleeve 12 through the rotating shaft 13, so that the fixing rod 14 can rotate around the rotating shaft 13 as the axis, and the angle of the cutter 15 can be adjusted. When the actual thickness of the rubber is greater, the angle between the cutter 15 and the material surface decreases. When the actual thickness of the rubber is smaller, the cutter 15 is more vertical and the angle between the cutter 15 and the material surface increases.
[0049] like Figure 1 , Figure 12 As shown, two sets of mounting plates 16 are fixedly connected to the outer surface of the support rod 11, and a base plate 17 is fixedly connected to the bottom between the two sets of mounting plates 16. A drive motor 18 is installed on one side of the mounting plate 16, and a bidirectional lead screw 19 is connected to the output end of the drive motor 18. A threaded sleeve 20 is threadedly connected to the outer surface of the bidirectional lead screw 19, and the top of the threaded sleeve 20 is fixedly connected to the fixed sleeve 12. A guide rod 21 is fixedly connected between the two sets of mounting plates 16, and the threaded sleeve 20 is slidably connected to the guide rod 21.
[0050] There is an electrical connection between the controller and the drive motor 18. The controller can remotely control the start of the drive motor 18. The output end of the drive motor 18 can drive the bidirectional lead screw 19 to rotate. When the bidirectional lead screw 19 rotates, it can drive the two sets of threaded sleeves 20 connected by the outer surface thread to move simultaneously to the middle or both sides, thereby adjusting the distance between the two sets of cutters 15.
[0051] like Figure 12As shown, a connecting block 22 is fixedly connected to the side of the threaded sleeve 20 near the tensioning mechanism 4. An electric push rod 23 is installed on the top of the connecting block 22. A rack 24 is fixedly connected to the top of the electric push rod 23. A toothed ring 25 is fixedly connected to the outside of the fixing rod 14. The toothed ring 25 is meshed with the rack 24.
[0052] The controller activates a set of electric push rods 23 to extend, which in turn drives the rack 24 to move upward, while another set of electric push rods 23 retracts, which in turn drives the rack 24 to move downward. This allows the gear ring 25, which meshes with the rack 24, to drive the fixed rod 14 to rotate, which in turn drives the cutter 15 to rotate around the rotating shaft 13, thereby adjusting the cutting angle of the cutter 15.
[0053] In this embodiment, the first step is to select operating parameters through the controller. The operating parameters include the initial tension pressure threshold P set by the pressure sensor 405, the initial rubber without tension measured by the first vision sensor 506, and the rubber parameters of the tensioned rubber material during the conveying process measured by the second vision sensor 508, all of which are normal thickness values T, normal area of surface wrinkles S, and normal dust concentration C measured by the dust concentration sensor 26.
[0054] Furthermore, when the rubber thickness value T and the normal value S of the surface wrinkle area are conveyed at a normal speed during the initial rubber conveying process, and the dust concentration value is C, the negative pressure fan 1002 maintains a constant power to suck up the dust, which can promptly remove the dust from the rubber surface and prevent the dust from adhering to the outer surface of the rubber, thereby ensuring the quality of the rubber.
[0055] In the second step, after the conveying mechanism 2 is started, the rubber material is conveyed through the conveying roller 3. Before entering the tensioning mechanism 4, the tensioning mechanism 4 can simultaneously detect the size thickness value T of the rubber material and the normal value S of the surface wrinkle area. At the same time, the dust concentration sensor 26 detects the dust concentration value and can adjust the dust suction power according to the concentration value.
[0056] Specifically, after the brush 502 brushes the surface of the rubber material, the impurities generated enter the hollow cavity 503 through the dust suction pipe 504, and then flow into the dust collection box 1001 through the connecting pipe 505 and the central pipe 1004. The filter screen of the air outlet 1003 intercepts the impurities, and the purified air can be discharged through the air outlet 1003.
[0057] Thirdly, the first vision sensor 506 can detect the surface of the untensioned material, obtain the actual initial rubber thickness T1 and the actual wrinkle area S1, and after the tensioning mechanism 4 is operated, the second vision sensor 508 measures the rubber parameters during the conveying process after the tensioning operation as the actual thickness value T2 and the actual surface wrinkle area S2.
[0058] Scenario 1: Before tensioning, if the local actual thickness value T1 > T and the local actual wrinkle area value S1 > S, it indicates that the thick material area is in a relaxed state. Because before tensioning, the material is not stretched by external force, and the excess material in the thick material area is not tightened, which easily causes accumulated wrinkles. At this time, the controller controls the cylinder 403 in the corresponding thick material area tensioning mechanism 4 to extend, so that the tensioning block 404 extends, that is, the actual P1 > P, thereby increasing the tension on the material, gradually eliminating local wrinkles, and preventing the impact on the cutting accuracy. After tensioning, the second vision sensor 508 measures the actual thickness value T2 ≤ T, and the surface wrinkle area S2 ≤ S, which indicates that the rubber has not become thinner due to excessive tension, and the initial wrinkles have been completely eliminated without new wrinkles. Finally, the material state is normal.
[0059] Scenario 2: Before tensioning, if the overall actual thickness value T1 ≤ T, but the actual wrinkle area value S1 > S, it indicates that the overall thickness of the material is qualified but there are large-area wrinkles. It can be determined that this is caused by local slack or stacking during the conveying process. At this time, the controller controls the cylinder 403 in the tensioning mechanism 4 corresponding to the wrinkle area to extend, and the tensioning block 404 applies appropriate tension to eliminate the wrinkles in a targeted manner. That is, the local actual P1 > P, and the local P1 = P. After tensioning, the second vision sensor 508 measures the actual thickness value T2 ≤ T, and the surface... If the area of wrinkles S2 ≤ S, it indicates that the tension adjustment is appropriate and the material has not been overstretched and thinned. The wrinkles are completely eliminated and the condition is normal. If S2 is still > S after tensioning and T2 < T, it indicates that the tension is too high, causing the material to become thinner in some areas and the wrinkles are not completely eliminated. The pressure of the tensioning block 404 needs to be adjusted back to shrink the tensioning block 404 in the thinned area back to its initial range. For areas where the wrinkles are not completely eliminated, the controller is used to control the cylinder 403 in the tensioning mechanism 4 to extend, so that the tensioning block 404 extends and increases the tension on the material.
[0060] Scenario 3: Before tensioning, if the actual thickness T1 < T and the actual wrinkle area S1 > S, it indicates that the material itself is too thin and has wrinkles. At this time, the controller controls the cylinder 403 in the tensioning mechanism 4 to extend slightly, and the tensioning block 404 applies a small tension, i.e., P1 ≥ P, to gradually eliminate the wrinkles. After tensioning, if the second vision sensor 508 measures T2 ≤ T and S2 ≤ S, it indicates that the wrinkles have been eliminated and the material has not become excessively thin due to tension, and the condition is qualified. If after tensioning, T2 < T1 and S2 ≤ S, it indicates that the tension is too large and the material becomes thinner further, and the tensioning force needs to be reduced.
[0061] Scenario 4: Before tensioning, if the actual thickness of the material T1 > T and the actual wrinkle area S1 ≤ S, it indicates that the thickness of the rubber material has increased. At this time, the controller controls the cylinder 403 in the tensioning mechanism 4 to extend, so that the four sets of tensioning blocks 404 extend, thereby increasing the tension on the material. After tensioning, if the material still has an actual thickness T1 > T and an actual wrinkle area S1 ≤ S after standing for a period of time, it indicates that the material quality is normal, only the thickness has changed.
[0062] It should be noted that if the actual thickness value T1 of the rubber material is greater than T and the actual dust concentration C1 is greater than C, it indicates that the rubber thickness is large and there is a lot of dust. It can be determined whether the thickness of the material is due to the large amount of dust and its tight adhesion, which causes the first vision sensor 506 or the second vision sensor 508 to misjudge the actual thickness of the rubber, thereby affecting the pressure adjustment accuracy of the tension pressure.
[0063] Specifically, at this time, the controller needs to extend the electric telescopic rod 6 to increase the distance between the two sets of cleaning structures, so as to avoid the brush 502 from excessively squeezing the material. At the same time, the initial constant power of the negative pressure fan 1002 is increased to increase the suction force until the actual dust concentration value C1≤C. Then the power is reduced and restored to constant power, which can save energy. If the material thickness value T1>T at this time, it means that the thickness of the rubber material is not related to the dust. If the material thickness value T1<T at this time, it means that the thickness of the rubber material is related to the dust, and the dust can be effectively cleaned by increasing the suction power.
[0064] If the actual thickness of the rubber material is measured to be T1 < T, the controller controls the electric telescopic rod 6 to retract, reducing the distance between the two sets of cleaning structures, ensuring that the brush 502 is in close contact with the material surface, thereby strengthening the cleaning of dust, avoiding wear on the cutter 15, and reducing the service life of the cutter 15.
[0065] For situations two and three, where wrinkles are not eliminated after tensioning, it can be determined whether the increased friction on the rubber surface due to uncleaned dust leads to uneven local stress during conveying, exacerbating wrinkles. Two sets of cleaning structures can be used to initially clean the dust on the surface of the rubber material, and then the tensioning mechanism 4 can be used to tension the rubber material again to eliminate wrinkles.
[0066] After the initial processing of cases three and four, the angle of the cutter 15 during the slitting process can be adjusted.
[0067] It should be noted that when the actual rubber thickness T2 > T, increasing the angle between the cutter 15 and the rubber surface, i.e., making the cutter 15 more "tilted," increases the force-bearing range and prevents excessive localized stress on the cutter 15 due to excessive rubber thickness, which could lead to incomplete cutting or tearing of the rubber surface. When the actual rubber thickness T2 ≤ T, decreasing the angle between the cutter 15 and the rubber surface, i.e., making the cutter 15 more "vertical," increases the concentration of cutting pressure, ensuring that thin rubber can be accurately cut and preventing cutting position deviation or incomplete cutting due to excessive angle. The cutter 15 is adjusted by a controller controlling a set of electric push rods 23. Extending and driving the corresponding rack 24 upward, another set of electric push rods 23 retracts and drives the corresponding rack 24 downward, causing the gear ring 25 meshing with the rack 24 to rotate clockwise or counterclockwise. This, in turn, drives the cutter 15 to rotate around the rotating shaft 13 via the fixed rod 14, thereby adjusting the angle of the cutter 15. When the actual thickness of the rubber is greater than the normal thickness, the angle between the cutter 15 and the material needs to be reduced, i.e., α is less than 90°. If the actual thickness of the rubber is less than the normal thickness, the cutter 15 is more vertical, i.e., α is equal to 90°. Intelligent cutting can be performed according to rubber materials of different thicknesses to ensure that the rubber can be accurately cut.

A conveying device for intelligent slitting of rubber, comprising a frame (1) and a controller mounted on one side of the frame (1), characterized in that: A conveying mechanism (2) is provided on one side of the frame (1), a feeding roller (3) is provided in the middle of the frame (1), and a tensioning mechanism (4) is provided below the frame (1). The tensioning mechanism (4) is located on one side below the feeding roller (3). The tensioning mechanism (4) includes a tensioning roller (401) fixedly connected to the frame (1). The tensioning roller (401) has four sets of placement slots (402) inside. A cylinder (403) is installed inside each of the four sets of placement slots (402). A tensioning block (404) is fixedly connected to the output end of the cylinder (403). There are four sets of tensioning blocks (404). A pressure sensor (405) is provided inside the tensioning block (404). A first dust cleaning mechanism (5) and a second dust cleaning mechanism (7) are provided on one side of the tensioning block (404). The first dust cleaning mechanism (5) includes a first fixing block (501) fixedly connected to one side of the tensioning block (404). Electric telescopic rods (6) are installed on both sides of the tensioning roller (401). The second dust cleaning mechanism (7) includes a second fixing block (701) connected to the output end of the electric telescopic rod (6). The first dust cleaning mechanism (5) is located below the second dust cleaning mechanism (7). The first fixing block (501) and the second fixing block (701) are connected to each other. A brush (502) is provided on one side of 01). The first fixing block (501) and the second fixing block (701) are each provided with four sets. A first vision sensor (506) is installed on the side of the first fixing block (501) and the second fixing block (701) away from the tension block (404). A dust concentration sensor (26) is installed on the side of the first vision sensor (506). A support frame (507) is provided on the side of the tension block (404) away from the first dust cleaning mechanism (5). A second vision sensor (508) is provided below the support frame (507). The operating parameters are selected by the controller. The operating parameters include the initial tension pressure threshold P set by the pressure sensor (405), the initial rubber without tension detected by the first vision sensor (506), and the rubber parameters of the tensioned rubber material during the conveying process detected by the second vision sensor (508). The rubber parameters are the normal thickness value T, the normal area of surface wrinkles S, and the normal dust concentration value C measured by the dust concentration sensor (26). The first vision sensor (506) can detect the surface of the untensioned material to obtain the actual initial rubber thickness T1 and the actual wrinkle area S1. After the operation of the tensioning mechanism (4), the rubber parameters measured by the second vision sensor (508) during the conveying process after the tensioning operation are the actual thickness value T2 and the actual area of surface wrinkles S2. Before tensioning, if the overall actual thickness value T1≤T, but the actual wrinkle area value S1>S, it indicates that the overall thickness of the material is qualified but there are large-area wrinkles. It is judged that this is caused by local slack or stacking during the conveying process. At this time, the controller controls the cylinder (403) in the tensioning mechanism (4) corresponding to the wrinkle area to extend, and the tensioning block (404) applies appropriate tension to eliminate the wrinkles in a targeted manner. That is, the local actual pressure value P1>P, the local actual pressure value P1=P. After tensioning, the second vision sensor (508) measures the actual thickness value T2≤T, and the surface If the area of the wrinkles S2 ≤ S, it means that the tension adjustment is appropriate and the material has not been overstretched and thinned. The wrinkles are completely eliminated and the state is normal. If S2 is still > S after tensioning and T2 < T, it means that the tension is too large, causing the material to become thin in some areas and the wrinkles are not completely eliminated. The pressure of the tensioning block (404) needs to be adjusted back to shrink the tensioning block (404) in the thinned area back to the initial range. For the area where the wrinkles are not completely eliminated, the cylinder (403) in the tensioning mechanism (4) is extended again through the controller, so that the tensioning block (404) extends and increases the tension on the material.
