Description

Technical Field

[0001] This utility model relates to the field of film winding and unwinding technology in the film production process, specifically a film winding and unwinding trolley. Background Technology

[0002] After the film is produced, it needs to be wound around a core tube by a winding machine to form a roll. During the winding process, the core tube is fitted around the winding roller, and the winding roller drives the core tube to rotate continuously, thereby continuously winding up the film material. When the set length and the film roll reach the set diameter, the film roll, along with the core tube, needs to be removed from the winding roller and transported to a designated position. This process is called "unwinding". After unwinding, a new spare core tube needs to be fitted onto the winding roller. This process is called "core loading".

[0003] Traditional film unloading processes rely mainly on manual labor, resulting in low automation, high labor intensity for workers, and the need to reload the core tube and adjust its position before rewinding, which is time-consuming and reduces winding efficiency.

[0004] In view of this, we propose a winding and unwinding trolley. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-6 The system includes a vehicle body 1, with casters fixedly mounted at the bottom, allowing the vehicle body 1 to move freely and transfer the film roll. Two side plates 2 are fixedly mounted on the vehicle body 1, and roller changing mechanisms 3 are installed on the two side plates 2. A take-up roller 4 is positioned between the roller changing mechanisms 3. The take-up roller 4 is used to wind up the film after it has been slit. The roller changing mechanisms 3 enable quick switching between the wound take-up roller 4 and the unwound take-up roller 4, reducing the impact of take-up roller 4 replacement on film winding and improving winding efficiency.

[0020] Please see Figures 2-5 The roller changing mechanism 3 includes a disassembly / assembly base 31, which is fixedly mounted on a side plate 2. A rotating groove 32 is formed on one side of the disassembly / assembly base 31, and a disassembly / assembly plate 34 is rotatably mounted within the rotating groove 32. The rotating groove 32 is composed of three interconnected circular grooves of different diameters. The disassembly / assembly plate 34 is rotatably mounted within the central circular groove of the rotating groove 32, allowing it to rotate along the rotating groove 32 without detaching from it. Two symmetrical mounting seats 35 are slidably mounted on the disassembly / assembly plate 34. The mounting seats 35 contact the two circular grooves inside and outside the rotating groove 32. The rotating groove 32 limits the movement of the mounting seats 35, preventing them from sliding along the disassembly / assembly plate 34. Furthermore, when the disassembly / assembly plate 34 rotates, the mounting seats 35 can also move along the rotating groove 32, thus achieving stable rotation of the disassembly / assembly plate 34 and the mounting seats 35.

[0021] Please see Figure 2 A sliding seat 37 is fixedly mounted on the surface of the mounting base 31. A winding motor 38 is slidably mounted on the sliding seat 37. The sliding seat 37 consists of two round rods and serves to limit and stabilize the winding motor 38, allowing the winding motor 38 to move along the sliding seat 37. A cylinder 39 is fixedly connected to the winding motor 38. By operating the cylinder 39, the winding motor 38 can be moved along the sliding seat 37, thereby controlling the position of the winding motor 38.

[0022] In addition, the output shaft of the winding motor 38 has a petal-shaped cross-section, and the output shaft of the winding motor 38 is inserted into the mounting base 35, so that after the output shaft is inserted into the mounting base 35, it can both limit the displacement of the mounting base 35 and drive the mounting base 35 to rotate.

[0023] Please see Figure 4 and Figure 5 The roller changing mechanism 3 also includes an abutment seat 310, which is fixedly connected to the side plate 2. The abutment seat 310 has a disc structure, and an abutment plate 311 is rotatably mounted on the abutment seat 310. The abutment plate 311 can rotate within the abutment seat 310. A limit block 313 is elastically mounted on the abutment plate 311 via a spring, so that the limit block 313 has a force to move towards the abutment seat 310 under the elastic force of the spring, making the limit block 313 in close contact with the surface of the abutment seat 310. A sliding groove 314 is provided on the abutment seat 310, and the limit block 313 is slidably connected to the sliding groove 314, so that when the limit block 313 moves to the position of the sliding groove 314, it moves into the sliding groove 314 under the action of the spring. The abutment plate 311 has a disassembly groove 312, and the disassembly groove 312 is connected to the limiting block 313. The disassembly groove 312 ensures that the winding roller 4 will not be disturbed when it is disassembled or assembled.

[0024] In addition, the abutment seat 310 is threadedly connected to the limit rod 315 at the position of the sliding groove 314. By rotating the limit rod 315, the displacement of the limit rod 315 along the abutment seat 310 can be controlled, thereby squeezing the limit block 313 in the sliding groove 314. Adjusting the position of the limit block 313 allows the limit block 313 to press the winding roller 4 and the rotation of the limit block 313 along the abutment seat 310 to be unaffected.

[0025] It should be noted that the two ends of the take-up roller 4 are respectively inserted into the limiting block 313 and the mounting base 35. The contact section between the take-up roller 4 and the mounting base 35 has a petal-shaped structure, which plays a role in stable connection and transmission. The limiting block 313 is a bowl-shaped structure with crossbars on both sides, and its interior is hemispherical. This allows the limiting block 313 to provide good abutment and support for take-up rollers 4 of different diameters without affecting the rotation of the take-up roller 4.

[0026] It is worth noting that the mounting base 31 has two symmetrically arranged through slots 36. The diameter of the through slot 36 near the take-up motor 38 is smaller than the diameter of the mounting base 35 but larger than the diameter of the output shaft of the take-up motor 38, ensuring that the mounting base 35 will not detach and will not affect the insertion of the output shaft of the take-up motor 38. The diameter of the symmetrical through slots 36 is larger than the diameter of the mounting base 35, allowing the mounting base 35 to move along the through slots 36 at these locations, releasing or opening the restriction on the take-up roller 4, facilitating the assembly and disassembly of the take-up roller 4. A notch 33 is provided on one side of the mounting base 31 for unwinding the take-up roller 4.

[0027] Please see Figure 6 A roll unloading mechanism 5 is provided between the vehicle body 1 and the side plate 2 for disassembling and storing the film roll and take-up roller 4 for convenient subsequent unified transportation. A lifting seat 51 is fixedly installed on the vehicle body 1, and a material unloading block 52 is fixedly installed on the top of the lifting seat 51. The lifting seat 51 can drive the material unloading block 52 to move up and down. The top of the material unloading block 52 is two square rods with "U"-shaped grooves, which are used to clamp the take-up roller 4 at both ends for convenient support and unloading of the take-up roller 4. The lifting seat 51 is driven by a hydraulic cylinder or a motor screw, etc.

[0028] In this embodiment, multiple sets of collection seats 53 are fixedly installed on the vehicle body 1. Each set of collection seats 53 consists of two square rods with "U"-shaped grooves at the top. The multiple sets of collection seats 53 are arranged in an array, and the height of the collection seats 53 away from the lifting seat 51 gradually increases. The collection seats 53 are used for temporary storage of the film roll and the winding roller 4.

[0029] In this embodiment, a rotating seat 54 is fixedly installed between the side plates 2. A collecting rod 55 is rotatably mounted on the rotating seat 54. The collecting rod 55 is used for limiting and conveying the film roll. The collecting rod 55 can rotate along the rotating seat 54, thereby adjusting the angle of the collecting rod 55 and thus adjusting the conveying direction of the film roll. A buffer seat 56 is elastically connected to the collecting rod 55. The elastic connection allows the buffer seat 56 to buffer and slow down the conveying of the film roll, preventing the film roll from moving too fast under the action of gravity when it moves along the collecting rod 55, which could cause impact damage. Multiple top blocks 57 are detachably connected to the vehicle body 1. The tops of the top blocks 57 contact the collecting rod 55, providing support for the collecting rod 55. Different numbers of top blocks 57 can support the collecting rod 55 at different rotation angles, facilitating the conveying of the film roll to different collecting seats 53 for storage.

[0030] A film unloading trolley, the working principle of which is as follows: When winding is finished, the winding motor 38 stops working. The cylinder 39 drives the winding motor 38 to move, causing the output shaft to disengage from the mounting base 35 and release the limit. By inserting the new winding roller 4 into the mounting base 35 away from the winding motor 38 and moving the mounting base 35 away from the through slot 36, and then rotating the limit rod 315, the limit rod 315 moves, causing the limit block 313 to move, thus disengaging the limit block 313 from the winding roller 4, and the winding roller 4 is now limited. Rotating the winding roller 4 causes the disassembly plate 34 and the abutment plate 311 to rotate 180 degrees, causing the old and new winding rollers 4 to switch positions. The cylinder 39 drives the winding motor 38 to move, causing the output shaft to insert into the mounting base 35. The new winding operation can then be started by starting the winding motor 38.

[0031] Start the lifting seat 51. The lifting seat 51 drives the unloading block 52 to move upward and engage with both ends of the take-up roller 4, which plays a supporting role for the take-up roller 4. Then, by rotating the limit rod 315, the limit block 313 is disengaged from the take-up roller 4, and the mounting seat 35 is moved towards the through groove 36, so that the mounting seat 35 is disengaged from the take-up roller 4, and the take-up roller 4 is released from fixation and limitation.

[0032] By rotating the collecting rod 55, the collecting rod 55 rotates along the rotating seat 54, thereby adjusting the angle of the collecting rod 55. The collecting rod 55 is supported by the top block 57. The lifting seat 51 operates, causing the unloading block 52 to move downwards, which in turn causes the winding roller 4 to move downwards. The winding roller 4 contacts the collecting rod 55. The lifting seat 51 continues to move downwards, causing the winding roller 4 to disengage from the unloading block 52, thus allowing the winding roller 4 to move along the collecting rod 55. During this movement, the winding roller 4 is buffered by the buffer seat 56 to prevent impact on the winding operation. The winding roller 4 moves along the collecting rod 55 to the collecting seat 53, where it is collected and held in place.
