DETAILED DESCRIPTION

[0029] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0030] Embodiment 1: An adaptive medicinal packaging composite film winding device, such as Figure 1-Figure 7 As shown, it includes an installation frame 1, on which two rotating sleeve rods 2 are rotatably connected, and the two rotating sleeve rods 2 are symmetrically arranged. Two motors 3 are fixedly connected to the installation frame 1, and the two motors 3 are symmetrically arranged. The output shafts of the two motors 3 are fixedly connected to the rotating sleeve rod 2 on the same side. A clamping component and a winding and pressing component are provided on the installation frame 1. The clamping component is used to clamp winding rollers 44 of different lengths to improve the applicability of the device. The winding and pressing component is used to press the composite film after winding to prevent the composite film from loosening and improve the winding quality of the device.

[0031] The clamping component includes a clamping rod 41, and the two rotating sleeve rods 2 are both slidably connected with the clamping rod 41. A first pressure spring 42 is connected between the clamping rod 41 and the rotating sleeve rod 2. The first pressure spring 42 is used to drive the clamping rod 41 to reset. The two clamping rods 41 are both fixedly connected with a limit ring 43, and a winding roller 44 is clamped between the two limit rings 43. The limit ring 43 is used to fix the winding roller 44. The two clamping rods 41 are both fixedly connected with a rotating mounting ring 45.

[0032] The winding and pressing component includes a mounting shell 51, two mounting shells 51 are slidably connected to the mounting frame 1, the mounting shell 51 is rotatably connected to the rotating mounting ring 45 located on the same side, a rotating shaft 52 is rotatably connected in the mounting shell 51, a pressure rod 53 and a column gear 54 are fixedly connected to the rotating shaft 52, the gear 54 is used to drive the rotating shaft 52 to rotate, a gear rod 55 is slidably connected in the mounting shell 51, the gear rod 55 and the column gear 54 are meshed, the gear rod 55 is used to drive the column gear 54 to rotate, and the mounting shell 51 and the gear rod 55 are meshed. A tension spring 56 is connected between the rods 55, and the tension spring 56 is used to drive the gear rod 55 to reset. A contact rod 57 is slidably connected to the mounting shell 51, and a reset spring 58 is connected between the mounting shell 51 and the contact rod 57. Two locking rods 59 are slidably connected in the mounting shell 51, and the locking rods 59 are used to fix the gear rod 55. A second pressure spring 510 is connected between the two locking rods 59 and the mounting shell 51, and the second pressure spring 510 is used to drive the locking rod 59 to reset. Two locking holes are provided on the locking rod 59.

[0033] The two locking rods 59 are symmetrically arranged on both sides of the contact rod 57 .

[0034] At first, the gear rod 55 is in contact with the contact rod 57, the tension spring 56 is in a stretched state, the gear rod 55 squeezes the locking rod 59, and the second pressure spring 510 is in a compressed state. The user first pushes the two clamping rods 41 away from each other, so that the clamping rod 41 will extend into the rotating sleeve rod 2, and the first pressure spring 42 is compressed. Then the user clamps the winding roller 44 between the two limit rings 43. The user releases the clamping rod 41, and the first pressure spring 42 resets and drives the clamping rod 41 to reset, so that the winding roller 44 is fixed between the two clamping rods 41. Subsequently, the user winds the reset film on the winding roller 44, and then the user starts the motor 3. The output shaft of the motor 3 rotates, and the rotation of the output shaft of the motor 3 drives the rotating sleeve rod 2 to rotate. The rotation of the rotating sleeve rod 2 will drive the clamping rod 41 and the winding roller to rotate, thereby winding the composite film. During the winding process of the composite film, the diameter of the composite film on the winding roller 44 will gradually increase, and the composite film will squeeze the contact rod 57, causing the contact rod 57 to move away from the mounting shell 51, and the reset spring 58 will be stretched. After the composite film is wound to the specified diameter, the contact rod 57 will fall off the gear rod 55, and the motor 3 will stop rotating. The reset of the tension spring 56 will drive the gear rod 55 to move toward the direction close to the motor 3. The movement of the gear rod 55 will mesh with the column gear 54, causing the column gear 54 to rotate. The rotation of the column gear 54 drives the rotating shaft 52 to rotate. The rotation of the rotating shaft 52 drives the pressure rod 53 to rotate 90 degrees. After the pressure rod 53 rotates 90 degrees, the pressure The rubber sheet 11 on the rod 53 will contact the composite film, and then press the composite film on the winding roller 44. Then the user cuts the composite film and fixes the composite film on the winding roller 44. Then the user rotates the pressure rod 53 in the direction close to and away from the winding roller 44, and the column gear 54 reverses. The reverse rotation of the column gear 54 drives the gear rod 55 to move in the opposite direction, and the tension spring 56 is stretched. During the reverse movement of the gear rod 55, the locking hole on the gear rod 55 passes through the locking rod 59, and the gear rod 55 no longer squeezes the locking rod 59. The second pressure spring 510 resets and drives the locking rod 59 to get stuck in the locking hole of the gear rod 55, thereby fixing the gear rod 55, thereby fixing the pressure rod 53. Then the user pulls the winding roller 44 from between the two clamping rods 41 The contact rod 57 is reset during the reset process, and the locking rods 59 on both sides are squeezed, so that the locking rods 59 will fall off the locking holes of the toothed bar 55. The tension spring 56 is reset, and the toothed bar 55 is reset. The toothed bar 55 contacts the contact rod 57 again, and the locking rod 59 is squeezed by the toothed bar 55. The second pressure spring 510 is compressed, and the toothed bar 55 is reset, driving the column gear 54 and the pressure rod 53 to reset, thereby completing the winding of the composite film. In this way, the device can wind up composite films of different widths, thereby improving the applicability of the device, and avoiding the loosening of the composite film on the winding roller 44 during the cutting of the composite film, thereby improving the winding quality of the composite film.

[0035] Embodiment 2: Based on embodiment 1, Figure 8-Figure 10 As shown, it also includes a broken film pressing component. The mounting frame 1 is provided with the broken film pressing component, which is used to press the cut composite film, so that the user can wind the composite film onto the next winding roller 44, thereby improving work efficiency. The broken film pressing component includes a first sliding mounting rod 61. Two first sliding mounting rods 61 are welded on the mounting frame 1, a fixed roller 62 is welded between the two first sliding mounting rods 61, and a sliding pressure roller 63 is slidably connected between the two first sliding mounting rods 61. A transmission rod 64 is fixedly connected to the two contact rods 57, and the two transmission rods 64 and the sliding pressure roller 63 are slidably connected. The transmission rod 64 is used to drive the sliding pressure roller 63 to slide, and the sliding pressure roller 63 moves toward the fixed roller 62 to clamp the composite film.

[0036] The mounting frame 1 is provided with a locking component, which is used to limit the rotation sleeve rod 2 to prevent the rotating sleeve rod 2 from rotating when the winding roller 44 is disassembled, thereby further improving the applicability of the device. The locking component includes a push rod 71, and the mounting frame 1 is slidably connected with two push rods 71, and the two push rods 71 ​​are symmetrically arranged. The two push rods 71 ​​are fixedly connected to the sliding pressure roller 63, and the mounting frame 1 is slidably connected with two squeezing rods 72, and the two squeezing rods 72 are symmetrically arranged. A third pressure spring 73 is connected between the two squeezing rods 72 and the mounting frame 1, and the third pressure spring 73 is used to drive the squeezing rod 72 to reset. The two squeezing rods 72 are fixedly connected with a limiting plate 74, and the limiting plate 74 is used to limit the rotation of the sleeve rod 2.

[0037] The two limiting plates 74 are made of soft rubber material.

[0038] At first, the user first passes the composite film through the fixed roller 62 and the sliding pressure roller 63 and then winds it on the winding roller 44. During the process that the contact rod 57 moves in the direction away from the mounting shell 51, the contact rod 57 drives the transmission rod 64 to move together. The movement of the transmission rod 64 drives the sliding pressure roller 63 to move in the direction close to the fixed roller 62. When the composite film on the winding roller 44 is wound to a specified diameter, the sliding pressure roller 63 and the fixed roller 62 clamp the composite film. After cutting the composite film, the user can quickly fix the composite film at the conveying end, and then can more quickly wind the composite film at the conveying end on the next winding roller 44. The contact rod 57 resets and drives the transmission rod 64 and the sliding pressure roller 63 to reset. In this way, after the winding is completed, the conveyed composite film can be clamped, and the user can more quickly wind the composite film at the conveying end on the next winding roller 44, avoiding the composite film at the conveying end from falling and wrinkling after cutting, thereby improving work efficiency.

[0039] The movement of the sliding pressure roller 63 in the direction close to the fixed roller 62 will drive the push rod 71 to move together. The push rod 71 will squeeze the squeezing rod 72 during the movement. At this time, the motor 3 stops rotating, so that the squeezing rod 72 will extend into the installation frame 1, the third pressure spring 73 is compressed, and the movement of the squeezing rod 72 will drive the limit plate 74 to move, so that the limit plate 74 will squeeze the rotating sleeve rod 2, so that the rotating sleeve rod 2 will be limited. The reset of the sliding pressure roller 63 will drive the push rod 71 to reset, and the push rod 71 and the squeezing rod 72 will fall off. The reset of the third pressure spring 73 drives the squeezing rod 72 and the limit plate 74 to reset, so that the limit plate 74 and the rotating sleeve rod 2 will fall off. In this way, the rotating sleeve rod 2 will be restricted during the disassembly of the winding roller 44, which is convenient for the user to disassemble the winding roller 44 and further improve the applicability of the device.

[0040] Embodiment 3: Based on embodiment 2, Figure 1-Figure 11 As shown, it also includes a second sliding mounting rod 8, two second sliding mounting rods 8 are welded on the mounting frame 1, a support plate 9 is slidably connected between the two second sliding mounting rods 8, and a fourth pressure spring 10 is connected between the two second sliding mounting rods 8 and the support plate 9. The fourth pressure spring 10 is used to drive the support plate 9 to reset.

[0041] The support plate 9 is arc-shaped so as to better support the winding roller 44 .

[0042] The two pressure rods 53 are both fixedly connected with a rubber sheet 11 .

[0043] During the process of disassembling the winding roller 44, the winding roller 44 will fall onto the support plate 9 after falling off from between the two clamping rods 41, and the drag rod will be pressed into the second sliding mounting rod 8, and the fourth pressure spring 10 will be compressed. After the winding roller 44 is removed from the support plate 9, the fourth pressure spring 10 will reset and drive the support plate 9 to reset. In this way, the user can better remove the winding roller 44, further improving the applicability of the device.

[0044] The above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
