Description

Technical Field

[0001] The invention relates to the technical field of medicinal composite film winding, in particular to a winding roller clamping component for medicinal composite film production equipment. Background Art

[0002] In the production process of pharmaceutical composite films, the winding roller clamping assembly, as one of the key equipment, undertakes the important tasks of lifting, replacing and driving the winding roller. The performance of this assembly directly affects the quality of the finished composite film, production efficiency and cost control. Although the traditional winding roller clamping assembly can meet the production needs to a certain extent, it still has many shortcomings when facing the high-precision and high-standard production of pharmaceutical composite films, especially in the cutting and replacement of the composite film roll.

[0003] When the existing winding roller clamping assembly is cutting the composite film and replacing the roll, the composite film is not properly attached to the roll, but is left in a loose state or not completely straightened. As a result, when the winder starts to operate, the head end of the composite film is easily folded on the roll. Once the end of the composite film is folded, the tension control system needs to be additionally adjusted during the winding process to adapt to this local thickness change. However, most traditional equipment is not equipped with a sufficiently intelligent tension adjustment mechanism and cannot respond to slight changes in the thickness of the composite film in real time, thereby increasing the risk of damage to the composite film or poor winding. In addition, since the folded part at the head end of the composite film is thicker than other parts, when the machine starts to wind, this part will form a thicker starting point. As the winding continues, this thickness difference may gradually accumulate, resulting in uneven diameter of the entire film roll, and may even have tapered or wavy edges, which is unacceptable for applications that require precise thickness control. Summary of the invention

[0004] In view of this, the present invention provides a winding roller clamping assembly for pharmaceutical composite film production equipment, which can solve the problem that when the existing winding roller clamping assembly is used to cut the composite film and replace the roll, the head end of the composite film is easily folded on the roll, which increases the risk of damage to the composite film or poor winding, and easily causes uneven diameter of the entire film roll.

[0032] See also Figure 2 As shown, the rotating mechanism includes a first servo motor 701 and a second servo motor 702; the first servo motor 701 is connected to the upper rear part of the first support frame 2 on the rear side, and the output shaft of the first servo motor 701 is connected to the rotating frame 4 on the rear side; the second servo motor 702 is symmetrically arranged on the left and right sides of the rear side of the rotating frame 4 on the rear side, and the output shaft of the second servo motor 702 is connected to the expansion shaft 6.

[0033] See also Figure 3 As shown, the driving mechanism includes a connecting frame 801 and an electric push rod 802; a connecting frame 801 is connected between the tops of the two first support frames 2; two electric push rods 802 are connected to the upper side of the connecting frame 801 and the left rear side of the top of the base plate 1, and the telescopic rods of the two electric push rods 802 on the connecting frame 801 are respectively connected to the two arc blocks 9 located above the expansion shaft 6, and the telescopic rods of the two electric push rods 802 on the base plate 1 are respectively connected to the two arc blocks 9 located below the expansion shaft 6.

[0034] See also Figure 5 and Figure 6 As shown, the moving mechanism includes a first one-way screw rod 1601 and a third servo motor 1602; the first one-way screw rod 1601 is rotatably connected to the upper side of the sliding frame 14, and the cutting knife 15 is threadedly connected to the first one-way screw rod 1601; the third servo motor 1602 is arranged on the upper front side of the sliding frame 14, and the output shaft of the third servo motor 1602 is connected to the front end of the first one-way screw rod 1601.

[0035] When in use, the empty roll is put on the expansion shaft 6 on the right, and the expansion shaft 6 on the right is controlled to fix the empty roll by expansion, and then the second servo motor 702 drives the rotating frame 4 to rotate 180 degrees counterclockwise, so that the first servo motor 701, the expansion shaft 6 and the second guide roller 5 on the rotating frame 4 rotate 180 degrees counterclockwise for transposition, so that the empty roll at this time is put on the expansion shaft 6 on the left through transposition, and then the head end of the composite film is pulled to pass over the top of the first guide roller 3, and then the head end of the composite film is pulled to pass under the expansion shaft 6 on the left, and then the composite film is cut and rolled up. First, the arc block 9, the sliding rod 10, the limit cylinder 12, the support plate 13 and the sliding frame are driven by the electric push rod 802. 14 moves to the side close to the left expansion shaft 6. When the support plate 13 and the sliding frame 14 come into contact with the composite film, the sliding frame 14 presses the composite film against the top of the support plate 13, and then releases the head end of the composite film, and drives the first one-way screw 1601 to rotate through the third servo motor 1602, so that the first one-way screw 1601 drives the cutting knife 15 to move backward, so that the cutting knife 15 cuts off the composite film on the top of the support plate 13, thereby removing the head end of the composite film (the head end of the composite film may be uneven, so this part needs to be removed when winding), and after the cutting knife 15 completes cutting the composite film on the top of the support plate 13, the removed part of the composite film is taken out manually, and the composite film is removed through the third servo motor 1602. The third servo motor 1602 drives the first one-way screw 1601 to reverse and reset, so that the first one-way screw 1601 drives the cutting knife 15 to move forward and reset, and then as the arc block 9, the sliding rod 10 and the limiting cylinder 12 on the lower side gradually approach the expansion shaft 6 on the left, the limiting cylinder 12 on the lower side will continuously push the composite film to the side close to the expansion shaft 6 on the left, so that the cut end of the composite film leaves from between the support plate 13 and the sliding frame 14, and the cut end of the composite film continuously approaches the empty roll on the left expansion shaft 6. At the same time, as the support plate 13 moves to the side close to the left expansion shaft 6, the support plate 13 will push the sliding frame 14 to move upward. When the limiting cylinders 12 on the upper and lower sides are close to the empty roll on the left expansion shaft 6 When in contact, the empty roll will block the upper and lower limit cylinders 12 and the sliding rod 10 from continuing to move. When the upper and lower arc blocks 9 continue to move toward the side close to the left expansion shaft 6, the first spring 11 is compressed until the upper and lower arc blocks 9 finally contact, so that the upper and lower limit cylinders 12 surround the left expansion shaft 6. During this period, as the first spring 11 is compressed, the first spring 11 will use its own elastic force to press the sliding rod 10 and the limit cylinder 12, so that the limit cylinder 12 squeezes the composite film tightly against the surface of the empty roll, thereby preventing the composite film from being in a relaxed state. Afterwards, the left expansion shaft 6 is driven counterclockwise by the first servo motor 701, so that the left expansion shaft 6 drives the empty roll to rotate counterclockwise.The empty roll thus utilizes friction to reel in the composite film (since the friction between the limit cylinder 12 and the sliding rod 10 is controlled to be smaller than the friction between the roll surface and the composite film, the roll has sufficient friction to reel in when it rotates). As the composite film is reeled in, the composite film surface will also utilize friction to drive the limit cylinder 12 to rotate on the sliding rod 10. This method of pressing the port of the composite film against the empty roll surface for reeling can prevent the port of the composite film from folding when the roll is reeled in. At the same time, as the composite film is reeled in, the diameter of the composite film on the roll gradually increases. The composite film on the roll will squeeze the limit cylinder 12 and the sliding rod 10, causing the first spring 11 to continue to compress. After the empty roll has reeled in the composite film for a certain number of turns, the electric The movable push rod 802 drives the arc block 9 and the support plate 13 to move and reset to the side away from the left expansion shaft 6, so that the arc blocks 9 on the upper and lower sides are separated. When the support plate 13 is separated from the sliding frame 14, the sliding frame 14 will fall downward under the influence of gravity until the sliding frame 14 is reset between the upper arc block 9, and as the arc blocks 9 on the upper and lower sides are separated, the first spring 11 will gradually return to its original state. When the first spring 11 returns to its original state, the arc block 9 will drive the sliding rod 10 and the limiting cylinder 12 to move and reset to the side away from the left expansion shaft 6 through the first spring 11, so that the limiting cylinders 12 on the upper and lower sides no longer surround the left expansion shaft 6, and the limiting cylinders 12 on the upper and lower sides are separated from the composite film on the reel, and then wait for the reel to reel up the composite film;

[0036] When the roll has finished winding the composite film, the first servo motor 701 drives the expansion shaft 6 on the left to stop rotating, so that the roll stops winding the composite film, and then the next empty roll is put on the expansion shaft 6 on the right, and the expansion shaft 6 on the right is controlled to fix the empty roll by expansion, and then the second servo motor 702 drives the rotating frame 4 to rotate 180 degrees counterclockwise, so that the first servo motor 701, the expansion shaft 6 and the second guide roller 5 on the rotating frame 4 rotate 180 degrees counterclockwise to exchange positions, so that the empty roll at this time is put on the expansion shaft 6 on the left through the exchange, and the roll that has completed winding is put on The roll that has completed winding is on the expansion shaft 6 on the right, and the composite film is pulled by the roll that has completed winding to pass under the second guide roller 5 on the lower side. Then the above-mentioned composite film cutting and winding operations are repeated, so that the subsequent composite film can be wound on the next empty roll. The expansion shaft 6 on the right is driven by the first servo motor 701 to rotate counterclockwise, so that the expansion shaft 6 on the right drives the roll thereon to wind up the cut tail end of the composite film, so that the roll on the right expansion shaft 6 can wind up the composite film completely. Then the expansion shaft 6 on the right is controlled to loosen the rolled roll by contraction, and then the rolled roll can be removed from the expansion shaft 6 on the right.

[0038] When the empty reel needs to be put onto the expansion shaft 6 on the right, the first reduction motor 20 is used to drive the second one-way screw 21 to rotate, so that the second one-way screw 21 drives the sliding frame 19 to move forward, thereby driving the docking plate 22 and the corresponding movable plate 17 to move forward, so that the corresponding movable plate 17 is separated from the rotating frame 4, and the movable plate 17 on the corresponding front side is detached from the expansion shaft 6 on the right. During this period, when the movable plate 17 moves forward, the movable plate 17 squeezes the first card bead 2502 to move toward the inside of the rotating frame 4, and the second spring 2503 is compressed to make the first card bead 2502 leave the first card slot 2501 of the movable plate 17. The movable plate 17 is separated from the first card bead 2502, and the second spring 2503 returns to its original state. The second spring 2503 drives the first card bead 2502 to move and reset in the direction away from the inside of the rotating frame 4. Then, when the empty reel is put on the right expansion shaft 6, the first reduction motor 20 drives the second one-way screw rod 21 to reverse and reset, so that the second one-way screw rod 21 drives the sliding frame 19 to move backward and reset, thereby driving the docking plate 22 and the corresponding movable plate 17 to move backward and reset, so that the movable plate 17 on the corresponding front side returns to the right expansion shaft 6, and the movable plate 17 on the corresponding front side pushes the empty reel to the middle of the right expansion shaft 6. The corresponding movable plate 17 is re-embedded in the rotating frame 4. During the period when the movable plate 17 moves backward to reset, when the movable plate 17 contacts the first card bead 2502, the movable plate 17 will squeeze the first card bead 2502 to move closer to the inside of the rotating frame 4. When the first card slot 2501 on the movable plate 17 is aligned with the first card bead 2502, the second spring 2503 returns to its original state, and the second spring 2503 drives the first card bead 2502 to move away from the inside of the rotating frame 4 and reset, so that the first card bead 2502 is re-engaged in the first card slot 2501 on the movable plate 17, thereby limiting the movable plate 17, and then driving by the second reduction motor 23. The bidirectional screw rod 24 rotates, so that the bidirectional screw rod 24 drives the docking plate 22 and the corresponding movable plate 17 to move to the middle position of the right expansion shaft 6, so that the corresponding movable plate 17 pushes the empty roll to the middle position close to the right expansion shaft 6, thereby centering the empty roll on the right expansion shaft 6, so that the position of the empty roll on the expansion shaft 6 can be consistent each time, thereby preventing the composite film from deviating when winding on the subsequent empty roll, and then the bidirectional screw rod 24 is driven by the second reduction motor 23 to reverse and reset, so that the bidirectional screw rod 24 drives the docking plate 22 and the corresponding movable plate 17 to move and reset to a position away from the middle position of the right expansion shaft 6;Then, when the rotating frame 4 rotates 180 degrees counterclockwise, the rotating frame 4 will drive the movable plate 17 to rotate 180 degrees counterclockwise, during which the movable plate 17 will squeeze the second card bead 2602 to move toward the direction of the inside of the docking plate 22, and the third spring 2603 will be compressed to make the second card bead 2602 leave the second card slot 2601 of the movable plate 17, and make the docking plate 22 leave the slide slot 1701 of the movable plate 17. When the movable plate 17 is separated from the second card bead 2602, the third spring 2603 will return to its original position. The third spring 2603 drives the second card bead 2602 to move and reset in the direction away from the inside of the docking plate 22. After the movable plate 17 is rotated and transposed, the docking plate 22 enters the slide groove 1701 of the corresponding movable plate 17, and when the corresponding movable plate 17 contacts the second card bead 2602, the corresponding movable plate 17 squeezes the second card bead 2602 to move in the direction close to the inside of the docking plate 22. The third spring 2603 is compressed. When the second card groove 2601 in the corresponding movable plate 17 is aligned with the second card bead 2602, The third spring 2603 returns to its original state, and the third spring 2603 drives the second clamping bead 2602 to move back to its original state away from the inside of the docking plate 22, so that the second clamping bead 2602 is clamped into the second clamping groove 2601 in the corresponding movable plate 17, thereby fixing the corresponding movable plate 17 to prevent the corresponding movable plate 17 from being separated from the docking plate 22; when the reel that has been wound up needs to be removed from the expansion shaft 6 on the right side, the second one-way screw 21 can be driven to rotate by the first reduction motor 20 again, so that the second one-way screw 21 drives the sliding frame 19 to move forward, thereby driving the docking plate 22 and the corresponding movable plate 17 to move forward, and then the corresponding movable plate 17 pushes the wound roll out of the right expansion shaft 6, thereby assisting the worker to discharge the wound roll from the right expansion shaft 6, and then the first reduction motor 20 drives the second one-way screw 21 to reverse and reset, so that the second one-way screw 21 drives the sliding frame 19 to move backward and reset, thereby driving the docking plate 22 and the corresponding movable plate 17 to move backward and reset. ;

[0039] See also Fig.11 and Fig.12 As shown, it also includes a lifting mechanism, which includes a second support frame 27, a slide 28, a hydraulic cylinder 29 and a roller 30; the second support frame 27 is connected to the front right side of the top of the base plate 1; a slide 28 is slidably arranged on the second support frame 27, and the slide 28 is used to support the reel; two hydraulic cylinders 29 are arranged at the lower right part of the second support frame 27, and the telescopic rods of the two hydraulic cylinders 29 are connected to the slide 28, and the hydraulic cylinder 29 is used to drive the slide 28 to lift and lower; a roller 30 for assisting the reel to move is rotatably arranged on the slide 28.

[0040] When the corresponding movable plate 17 pushes the completed reel from the right expansion shaft 6 forward, the completed reel will gradually detach from the right expansion shaft 6, and the completed reel will gradually enter the top of the slide 28, so that the slide 28 supports the completed reel. When the completed reel contacts the roller 30 on the slide 28, the completed reel will use friction to drive the roller 30 to roll, and the roller 30 will also reduce the resistance of the completed reel to move forward, thereby assisting the completed reel to move forward on the top of the slide 28. When the completed reel is completely detached from the right expansion shaft 6, the slide 28 is driven downward by the hydraulic cylinder 29 to drive the completed reel thereon to descend, and then the completed reel is manually removed from the top of the slide 28. In this way, it is convenient for workers to discharge the completed reel, and then the slide 28 is driven upward by the hydraulic cylinder 29 to be reset.
