Description

Technical Field

[0001] This invention relates to the field of slitting machine technology, and in particular to a multi-zone high-speed biaxial slitting machine for the production of composite film bags. Background Technology

[0002] Composite membranes are made of two different membrane materials, one of which is a surface-active layer with separation function and the other of which is a porous layer with support function. When producing composite membrane bags, a slitting machine is usually used to cut the composite membrane bags into multiple narrow strips. Using biaxial winding at the winding point of the slitting machine can greatly increase the capacity of the slitting machine.

[0003] The inventors discovered in their daily work that when the slitting machine is in use, the left and right sides of the slitting bag may fold when the rotating shaft drives the slitting bag into the outer surface of the winding shaft. This causes the slitting bag to wrap around the outer surface of the winding shaft, resulting in wrinkles. The slitting bag needs to be removed and rewound, which reduces the output efficiency of the slitting machine.

[0004] To address the issue that when a slitting machine uses a rotating shaft to guide the slitting composite film bag onto the outer surface of the winding shaft, folds may occur on both sides of the bag, causing wrinkles and requiring the bag to be removed and rewound, thus reducing the slitting machine's output efficiency. Existing technology involves installing two rotatable cylindrical rods at the front end of the composite film bag entering the winding shaft. The bag passes between these rods and is flattened by the rods to keep both sides smooth. However, the angle between the two rods is fixed, making it impossible to adjust the spacing based on the thickness of the composite film bag. This results in an incomplete solution for preventing wrinkles caused by folding. Summary of the Invention

[0005] This invention addresses the problem of installing two rotatable cylindrical rods at the front end of a composite film bag entering a take-up shaft, allowing the bag to pass between the rods onto the outer surface of the shaft. While the rods flatten the bag's surface, keeping both sides flat, the angle between the rods is fixed, making it impossible to adjust the rod spacing according to the bag's thickness. This results in inadequate protection against wrinkles caused by bag folding. Therefore, this invention proposes a multi-zone high-speed biaxial slitting machine for composite film bag production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: It includes a machine body; a first motor is disposed on one side of the outer surface of the machine body; a feeding roller is fixedly connected to the output end of the first motor; the outer surface of the feeding roller rotates on the inner wall of the machine body; several positioning rollers are rotatably connected to one side of the outer surface of the machine body; a slitting head and a collecting roller are disposed on the outer surface of the machine body away from the feeding roller; the outer surface of the collecting roller rotates on the outer surface of the machine body; two second motors are disposed on the outer surface of the machine body away from the first motor; a take-up roller is fixedly connected to the output end of the second motor; the outer surface of the take-up roller rotates on the outer surface of the machine body. A cutting head is provided on the outer surface of the machine body near the take-up roller. An adjustment device is provided on the outer surface of the machine body near the cutting head. The adjustment device includes a first cylindrical rod. The left and right sides of the outer surface of the first cylindrical rod are rotatably connected to the outer surface of the machine body. Two rectangular grooves are formed on the left and right sides of the outer surface of the machine body near the first cylindrical rod. A sliding rod is slidably connected to the inner wall of the rectangular groove. A second cylindrical rod is rotatably connected to the outer surface of the sliding rod. Threaded holes and round holes are formed on the left and right sides of the outer surface of the sliding rod. A threaded rod is rotatably connected to the bottom end of the inner wall of the rectangular groove. The outer surface of the threaded rod is threadedly connected to the inner wall of the threaded hole.

[0007] The effect achieved by the above-mentioned components is as follows: by setting threaded rods, the composite film bag is flattened by the first cylindrical rod and the second cylindrical rod to prevent the composite film bag from folding. The threaded rod can be rotated to rotate within the threaded hole and the inner wall of the rectangular groove, causing the sliding rod to slide up and down within the inner wall of the rectangular groove, changing the distance between the sliding rod and the first cylindrical rod. The spacing between the first cylindrical rod and the second cylindrical rod can be adjusted to accommodate composite film bags of different thicknesses, making the first cylindrical rod and the second cylindrical rod more effective and adaptable when flattening composite film bags of different thicknesses.

[0008] Preferably, an operating block is fixedly connected to the top of the outer surface of the threaded rod, and a plurality of protrusions are fixedly connected to the outer surface of the operating block, the protrusions being circumferentially distributed on the outer surface of the operating block.

[0009] The effect achieved by the above components is that rotating the operating block at the protrusion makes it easier to push the operating block to control the rotation of the threaded rod.

[0010] Preferably, two blocks are fixedly connected to the left and right sides of the outer surface of the sliding rod, and the outer surfaces of the two blocks slide on the left and right sides of the outer surface of the machine body, respectively.

[0011] The effect achieved by the above components is that when the sliding rod slides on the inner wall of the slide groove, the two blocks will slide on the left and right sides of the outer surface of the machine body. The blocks can fix the angle between the sliding rod and the machine body, increasing the stability of the sliding rod when it moves.

[0012] Preferably, a positioning rod is fixedly connected to the outer surface of the machine body away from the threaded rod, and the outer surface of the positioning rod slides on the inner wall of the circular hole.

[0013] The effect achieved by the above components is as follows: when the sliding rod is controlled to slide on the inner wall of the rectangular groove by rotating the threaded rod, the inner wall of the sliding rod will slide on the outer surface of the positioning rod at the circular hole. The positioning rod can fix the angle between the sliding rod and the first cylindrical rod, and avoid the angle between the first cylindrical rod and the second cylindrical rod from deflecting as much as possible.

[0014] Preferably, two grooves are formed on the left and right sides of the outer surface of the second cylindrical rod, and the two grooves are threaded grooves with opposite directions.

[0015] The effect achieved by the above components is that when the composite film bag passes between the first cylindrical rod and the second cylindrical rod, the two grooves on the outer surface of the second cylindrical rod will stretch the left and right sides of the composite film bag, further preventing the composite film bag from folding.

[0016] Preferably, the outer surface of the sliding rod is provided with a cleaning device, the cleaning device including two rings, the inner walls of the two rings rotating on the outer surface of the sliding rod, a tapered rod fixedly connected to the outer surface of the two rings, a brush rod fixedly connected to the outer surface of the tapered rod, a semi-circular groove being opened on the outer surface of the machine body near the threaded rod, a push rod being fixedly connected to the outer surface of the brush rod, and the push rod sliding on the inner wall of the semi-circular groove.

[0017] The effect achieved by the above components is as follows: by setting the brush rod, pushing the push rod to slide on the inner wall of the semi-circular groove to the bottom of the semi-circular groove, the brush rod can be positioned at the front end of the first cylindrical rod and the second cylindrical rod, so that after the composite film bag passes between the first cylindrical rod and the second cylindrical rod, it will contact the bottom end of the outer surface of the brush rod. The brush on the outer surface of the brush rod can clean the outer surface of the composite film bag as much as possible, avoiding dust adhering to the outer surface of the composite film bag, which would require secondary cleaning of the composite film bag and affect processing efficiency.

[0018] Preferably, a groove block is fixedly connected to the outer surface of the machine body near the threaded rod, and an L-shaped block is slidably connected to the inner wall of the groove block.

[0019] The effect achieved by the above components is that when the push rod is located at the bottom of the inner wall of the semi-circular groove, it can push the L-shaped block to slide on the inner wall of the groove block to the top of the push rod, thereby fixing the position of the push rod and the brush rod.

[0020] Preferably, a magnetic block is fixedly connected to the side of the outer surface of the machine body near the semi-circular groove, and the end of the outer surface of the push rod away from the machine body is made of metal.

[0021] The effect achieved by the above components is as follows: when it is not necessary to use a brush rod to clean the outer surface of the composite film bag, the push rod can be pushed to the top of the inner wall of the semi-circular groove so that one end of the outer surface of the push rod contacts the outer surface of the magnetic block. The push rod can be fixed to the top of the inner wall of the semi-circular groove by the magnetic attraction between the magnetic block and the top of the outer surface of the push rod.

[0022] Preferably, the outer surface of the sliding rod is provided with a polishing device, the polishing device includes a connecting rod, a polishing rod is fixedly connected to the outer surface of the connecting rod, a positioning block is fixedly connected to one side of the outer surface of the connecting rod, a third motor is provided on one side of the outer surface of the machine body, a positioning groove is opened inside the output end of the third motor, and a through hole is opened on the side of the outer surface of the machine body away from the third motor.

[0023] The effect achieved by the above components is as follows: by inserting the end of the connecting rod away from the positioning block into the through hole, and then inserting the positioning block on the outer surface of the connecting rod into the inside of the positioning groove, the connecting rod is pushed to slide on the inner wall of the through hole so that the positioning block is completely inside the positioning groove. The grinding rod can be set on one side of the outer surface of the first cylindrical rod and the second cylindrical rod. The operating motor drives the connecting rod and the grinding rod to rotate. The grinding rod can grind the outer surfaces of the first cylindrical rod and the second cylindrical rod, so that the outer surfaces of the first cylindrical rod and the second cylindrical rod remain smooth, and prevent the first cylindrical rod and the second cylindrical rod from affecting the surface characteristics of the composite film bag when the composite film bag passes through the first cylindrical rod and the second cylindrical rod.

[0024] Preferably, a threaded groove is formed on the outer surface of the connecting rod away from the positioning block, and a threaded ring is threadedly connected to the outer surface of the threaded groove.

[0025] The effect achieved by the above components is as follows: when the connecting rod is inside the through hole, the threaded ring can be fitted onto the threaded groove on the outer surface of the connecting rod. Rotating the threaded ring to bring it closer to the outer surface of the machine body can fix the position of the connecting rod and prevent the positioning block from dislodging from the positioning groove when the connecting rod rotates.

[0026] In summary, the beneficial effects of the present invention are as follows:

[0027] By setting threaded rods, the composite film bag is flattened by the first and second cylindrical rods to prevent folding. The threaded rods can be rotated to rotate within the threaded hole and the inner wall of the rectangular groove, causing the sliding rod to slide up and down within the inner wall of the rectangular groove. This changes the distance between the sliding rod and the first cylindrical rod, adjusting the spacing between the first and second cylindrical rods to accommodate composite film bags of different thicknesses. This results in better flattening of composite film bags of different thicknesses by the first and second cylindrical rods, and improved adaptability.

[0028] By setting up a brush rod, pushing the push rod to slide along the inner wall of the semi-circular groove to the bottom of the semi-circular groove, the brush rod can be positioned at the front end of the first cylindrical rod and the second cylindrical rod. This allows the composite film bag to contact the bottom end of the outer surface of the brush rod after passing between the first and second cylindrical rods. The brush on the outer surface of the brush rod can clean the outer surface of the composite film bag, minimizing the amount of dust adhering to the outer surface of the composite film bag, thus avoiding the need for secondary cleaning and affecting processing efficiency.

[0029] By inserting the end of the connecting rod away from the positioning block into the through hole, and then inserting the positioning block on the outer surface of the connecting rod into the inside of the positioning groove, the connecting rod is pushed to slide against the inner wall of the through hole so that the positioning block is completely inside the positioning groove. The grinding rod can be set on one side of the outer surface of the first cylindrical rod and the second cylindrical rod. The motor drives the connecting rod and the grinding rod to rotate. The grinding rod can grind the outer surfaces of the first cylindrical rod and the second cylindrical rod, so that the outer surfaces of the first cylindrical rod and the second cylindrical rod remain smooth, and prevent the first cylindrical rod and the second cylindrical rod from affecting the surface characteristics of the composite film bag when the composite film bag passes through the first cylindrical rod and the second cylindrical rod.

A first motor 5 is arranged on one side of the outer surface of the machine body 1. The output end of the first motor 5 is fixedly connected to a feeding roller 6. The outer surface of the feeding roller 6 rotates on the inner wall of the machine body 1. Several positioning rollers 7 are rotatably connected to one side of the outer surface of the machine body 1. A slitting head 8 and a collecting roller 9 are arranged on the outer surface of the machine body 1 away from the feeding roller 6. The outer surface of the collecting roller 9 rotates on the outer surface of the machine body 1. Two second motors 10 are arranged on the outer surface of the machine body 1 away from the first motor 5. A take-up roller 11 is fixedly connected to the output end of the second motor 10. The outer surface of the take-up roller 11 rotates on the outer surface of the machine body 1. A cutting head 12 is arranged on the outer surface of the machine body 1 near the take-up roller 11. An adjusting device 2 is arranged on the outer surface of the machine body 1 near the cutting head 12. The adjusting device 2 includes a first cylindrical rod 21. The left and right sides of the outer surface of the first cylindrical rod 21 are rotatably connected to the outer surface of the machine body 1. The outer surface of the machine body 1 near the first cylindrical rod 21 is rotatably connected to the outer surface of the machine body 1. Two rectangular grooves 25 are formed on the left and right sides of the rectangular groove 21. A sliding rod 22 is slidably connected to the inner wall of the rectangular groove 25. A second cylindrical rod 23 is rotatably connected to the outer surface of the sliding rod 22. Threaded holes 210 and round holes 211 are formed on the left and right sides of the outer surface of the sliding rod 22. A threaded rod 26 is rotatably connected to the bottom end of the inner wall of the rectangular groove 25. The outer surface of the threaded rod 26 is threadedly connected to the inner wall of the threaded hole 210. By setting the threaded rod 26, the composite film bag is laminated through the first cylindrical rod 21 and the second cylindrical rod 23. To flatten the composite film bag and prevent folding, the threaded rod 26 can be rotated to rotate within the threaded hole 210 and the inner wall of the rectangular groove 25, causing the sliding rod 22 to slide up and down within the inner wall of the rectangular groove 25. This changes the distance between the sliding rod 22 and the first cylindrical rod 21, and adjusts the spacing between the first cylindrical rod 21 and the second cylindrical rod 23 to accommodate composite film bags of different thicknesses. This results in better flattening of composite film bags of different thicknesses by the first cylindrical rod 21 and the second cylindrical rod 23, and improved adaptability.

[0041] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 as well as Figure 6As shown, this embodiment discloses that an operating block 27 is fixedly connected to the top of the outer surface of the threaded rod 26. Several protrusions 212 are fixedly connected to the outer surface of the operating block 27. The protrusions 212 are circumferentially distributed on the outer surface of the operating block 27. Rotating the operating block 27 at the protrusions 212 can more conveniently push the operating block 27 to control the rotation of the threaded rod 26. Two grooves 24 are opened on the left and right sides of the outer surface of the second cylindrical rod 23. The two grooves 24 are threaded grooves with opposite directions. When the composite film bag passes between the first cylindrical rod 21 and the second cylindrical rod 23, the two grooves 24 on the outer surface of the second cylindrical rod 23 will extend the left and right sides of the composite film bag, further preventing the composite film bag from folding.

The cleaning device 3 includes two rings 31, the inner walls of which rotate on the outer surface of the sliding rod 22. A tapered rod 32 is fixedly connected to the outer surface of the two rings 31, and a brush rod 33 is fixedly connected to the outer surface of the tapered rod 32. A semi-circular groove 35 is provided on the outer surface of the machine body 1 near the threaded rod 26. A push rod 34 is fixedly connected to the outer surface of the brush rod 33, and the push rod 34 slides on the inner wall of the semi-circular groove 35. By setting the brush rod 33, the cleaning device 3 can clean the sliding rod 22. The brush rod 33 pushes the push rod 34 to slide along the inner wall of the semi-circular groove 35 to the bottom of the semi-circular groove 35, so that the brush rod 33 is located at the front end of the first cylindrical rod 21 and the second cylindrical rod 23. This allows the composite film bag to contact the bottom end of the outer surface of the brush rod 33 after passing between the first cylindrical rod 21 and the second cylindrical rod 23. The brush on the outer surface of the brush rod 33 can clean the outer surface of the composite film bag as much as possible, avoiding dust adhering to the outer surface of the composite film bag, which would require secondary cleaning of the composite film bag and affect processing efficiency.

The grinding device 4 includes a connecting rod 42, a grinding rod 43 fixedly connected to the outer surface of the connecting rod 42, and a positioning block 44 fixedly connected to one side of the outer surface of the connecting rod 42. A third motor 45 is provided on one side of the outer surface of the machine body 1. A positioning groove 46 is opened inside the output end of the third motor 45. A through hole 41 is opened on the side of the outer surface of the machine body 1 away from the third motor 45. By inserting the end of the outer surface of the connecting rod 42 away from the positioning block 44 into the through hole 41, and then inserting the positioning block 44 on the outer surface of the connecting rod 42 into the positioning groove 46. Inside, the connecting rod 42 is pushed to slide on the inner wall of the through hole 41 so that the positioning block 44 is completely inside the positioning groove 46. The grinding rod 43 can be set on one side of the outer surface of the first cylindrical rod 21 and the second cylindrical rod 23. The motor drives the connecting rod 42 and the grinding rod 43 to rotate. The grinding rod 43 can grind the outer surface of the first cylindrical rod 21 and the second cylindrical rod 23, so that the outer surface of the first cylindrical rod 21 and the second cylindrical rod 23 remains smooth, and the first cylindrical rod 21 and the second cylindrical rod 23 are prevented from affecting the surface characteristics of the composite film bag when the composite film bag passes through the first cylindrical rod 21 and the second cylindrical rod 23.

[0046] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 as well as Figure 8 As shown, this embodiment discloses that a threaded groove 47 is provided on the outer surface of the connecting rod 42 away from the positioning block 44. A threaded ring 48 is threadedly connected to the outer surface of the threaded groove 47. When the connecting rod 42 is inside the through hole 41, the threaded ring 48 can be fitted onto the threaded groove 47 on the outer surface of the connecting rod 42. Rotating the threaded ring 48 so that it is close to the outer surface of the body 1 can fix the position of the connecting rod 42 and prevent the positioning block 44 from disengaging from the positioning groove 46 when the connecting rod 42 rotates.

[0047] The working principle is as follows: When using a slitting machine to slit composite film bags, the composite film bag is first rolled onto the outer surface of the feeding roller 6. Then, the end of the composite film bag away from the feeding roller 6 is connected to the outer surface of the positioning roller 7. The composite film bag is pulled so that it passes through the outer surfaces of the positioning roller 7 and the collecting roller 9, between the first cylindrical rod 21 and the second cylindrical rod 23, and is fixed at the outer surface of the take-up roller 11. Then, according to the thickness of the composite film bag, the operating block 27 is rotated at the protrusion 212 to control the threaded rod 26 to rotate on the inner wall of the threaded hole 210, so that the left and right sides of the sliding rod 22 slide on the inner wall of the rectangular groove 25, changing the distance between the second cylindrical rod 23 and the first cylindrical rod 21 and fixing it, so that the first cylindrical rod 21 and the second cylindrical rod 23... The spacing is matched with the thickness of the composite film bag. During the movement of the sliding rod 22 on the inner wall of the rectangular groove 25, the squares 29 on the left and right sides of the outer surface will slide on the outer surface of the machine body 1 to fix the angle between the sliding rod 22 and the machine body 1, increasing the stability during movement. At the same time, the round hole 211 on the inner wall of the sliding rod 22 will slide on the outer surface of the positioning rod 28. The positioning rod 28 keeps the angle between the sliding rod 22 and the first cylindrical rod 21 fixed, and avoids the angle between the first cylindrical rod 21 and the second cylindrical rod 23 from being skewed, which would affect the flatness of the composite film bag. Then, the first motor 5 drives the feeding roller 6 to rotate, causing the composite film bag outside the feeding roller 6 to move towards the winding roller 11. At the same time, the positioning roller 7 will guide the composite film bag to the distribution point. The composite film bag is cut at the cutting head 8. The cut composite film bag is rolled onto the outer surface of the collecting roller 9. Then, the second motor 10 drives the take-up roller 11 to rotate, so that the original composite film bag is rolled onto the outer surface of the take-up roller 11 between the first cylindrical rod 21 and the second cylindrical rod 23. The two reverse threaded grooves 24 on the outer surface of the second cylindrical rod 23 can stretch the left and right ends of the composite film bag to further prevent the composite film bag from folding. When the composite film bag on the outer surface of one take-up roller 11 is full, the operation of the first motor 5 and the second motor 10 can be stopped. The composite film bag is cut by the cutting head 12 and connected to the other take-up roller 11. Pushing the push rod 34 can control the push rod 34 to slide on the inner wall of the semi-circular groove 35. The angle of the brush rod 33 is adjusted by rotating the ring 31 on the outer surface of the sliding rod 22 via the tapered rod 32, so that the brush rod 33 is positioned above the passage of the composite film bag. The L-shaped block 37 is pushed so that it slides on the inner wall of the groove block 36 to above the push rod 34, fixing the position of the push rod 34 inside the semi-circular groove 35. When the composite film bag passes under the brush rod 33, the brush on the outer surface of the brush rod 33 cleans the outer surface of the composite film bag. When the machine body 1 is not in use, the push rod 34 can be pushed so that it slides on the inner wall of the semi-circular groove 35 to the top of the semi-circular groove 35. The position of the push rod 34 is fixed by magnetic connection between the magnetic block 38 and the outer surface of the push rod 34. When the machine body 1 stops operating, the connecting rod 42 can be passed through the through hole 41.Then, push the connecting rod 42 so that the positioning hole on the other side of the connecting rod 42 is inserted into the positioning groove 46 inside the output end of the third motor 45. Then, push the connecting rod 42 to slide against the inner wall of the through hole 41 so that the positioning block 44 is completely inside the positioning groove 46. Place the threaded ring 48 onto the threaded groove 47 on the outer surface of the connecting rod 42 and rotate the threaded ring 48 to fix it close to the outer surface of the machine body 1. Operating the third motor 45 can drive the connecting rod 42 and the grinding rod 43 to rotate. The grinding rod 43 can grind the outer surfaces of the first cylindrical rod 21 and the second cylindrical rod 23 to keep them smooth and avoid affecting the surface properties of the composite film bag.
