Description

Technical Field

[0001] This utility model relates to the field of transportation device technology, and in particular to a film master roll transportation device. Background Technology

[0002] Generally, the layout of a BOPP film production line is that the film-making workshop and the slitting workshop are connected in series. So, when the film-making master roll is fully wound up, it is directly lifted by a crane to the aging rack in the slitting workshop. After the aging is complete, the master roll is directly lifted by a crane to the slitting machine for cutting according to the length required by the customer.

[0003] However, due to space limitations, some BOPP film production lines can only have their film-making workshops and slitting workshops arranged side by side. In this layout, due to space constraints, it is not suitable to directly use a crane to transport the film rolls from the film-making workshop to the aging rack in the slitting workshop. Therefore, a film transport vehicle is needed to transport the film rolls. However, most current film transport devices adopt a real-time powered motor drive structure with synchronous cable dragging. This structure requires the installation of complex supports and cables that move in real time with the film transport vehicle. Not only is the structure of the device complex, but the synchronously moving cables are also prone to getting tangled with other equipment, tripping the operators. At the same time, the film rolls are prone to rolling during transportation, which can easily cause injury to the operators' hands, resulting in insufficient safety. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to propose a film roll transport device that solves the problems of existing film roll transport vehicles where the cable must move with the vehicle in real time and the support structure is complex, while the film roll roll rolls roll and collide during transport, causing injury to people's hands.

Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish and describe features, without any order or emphasis.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figures 1 to 4 As shown, a film roll transport device includes a frame 1, a limiting component 2, a drive component 3, and a wheel component 4; One end of the frame 1 is provided with a first support part 11, the first support part 11 is provided with an installation hollow area 111 and an installation support part 112; the other end of the frame 1 is provided with a movable second support part 12, the first support part 11 and the second support part 12 cooperate to support the film master roll along the length direction of the frame 1. The limiting component 2 is respectively installed on the top of the first support part 11 and the second support part 12. The limiting component 2 is used to restrict the film roll from rolling in the width direction of the frame 1. The wheel assembly 4 is mounted on the bottom of the frame 1; The drive assembly 3 includes a drive motor 31, a control box 32, and a battery 33. The control box 32 is electrically connected to the drive motor 31 and the battery 33. The control box 32 is installed in the mounting cutout area 111. The control box 32 is used to control the start, stop, and steering of the drive motor 31. The battery 33 is installed on the outside of the mounting support portion 112. The drive motor 31 is installed inside the frame 1 and is connected to the wheel assembly 4 in a transmission manner.

[0027] This invention proposes a film roll transport device. Firstly, by designing the control box 32 and battery 33, it eliminates the need for external power cables, enabling cable-free movement, reducing maintenance workload and costs. Secondly, by providing a dedicated mounting perforation area 111 for the control box 32 and a mounting support section 112 for the battery 33 on the first support section 11, the structural layout of the film roll transport device becomes more rational without increasing maintenance difficulty. If a malfunction occurs during transport, workers can perform maintenance on the control box 32 and battery 33 without moving the film roll on the transport device. Specifically, the mounting support section 112 provides lateral support for the battery 33, preventing it from tipping over during transport. Simultaneously, the battery 33 is located outside the mounting support section 112, and the control box 32 is located in the mounting perforation area 111, facilitating subsequent wiring or replacement maintenance of the battery 33 and control box 32. In addition, a limiting component 2 is added to restrict the rolling of the film roll in the width direction of the frame 1, so that the film roll does not need to be manually restricted by the operator during transportation, thus avoiding injury to the operator's hands from rolling collisions. This solves the problems of existing film roll transport vehicles where the cable needs to move with the vehicle in real time and the bracket structure is complex, and also solves the problem of injury to the operator's hands from rolling collisions during transportation.

[0028] It should be noted that the control box 32 is equipped with external control buttons (such as forward button, reverse button, pause button, etc.) and has a built-in PLC / motion control module to drive and control the forward and reverse rotation and speed of the drive motor 31, so that the operator can control the forward or backward movement of the film roll transport device. The battery 33 supplies power to the control box 32, and the control box 32 controls whether to supply power to the drive motor 31. This is prior art and will not be described in detail here.

[0029] Preferably, the drive assembly 3 further includes a gearbox 34, a first gear 35, a second gear 37, and a chain 36. The output shaft of the drive motor 31 is connected to the input end of the gearbox 34. The output shaft of the gearbox 34 is fixedly connected to the first gear 35. The first gear 35 and the second gear 37 are connected by transmission through the chain 36. The second gear 37 is fixedly sleeved on the axle 42 of the wheel assembly 4.

[0030] Specifically, such as Figure 2 As shown, the drive motor 31 is sequentially connected to the axle 42 via a gearbox 34, a first gear 35, a chain 36, and a second gear 37. The gearbox 34 has the function of reducing speed and increasing torque. At the same time, the transmission via the chain 36 can effectively distribute the load and reduce the force on a single tooth of the first gear 35 and the second gear 37. This can reduce the impact of the speed fluctuation of the drive motor 31 on the rotating shaft 23, and further reduce the rolling or offset of the film roll caused by sudden changes in speed. While satisfying the driving of the drive assembly 3 on the wheel assembly 4, it further improves the safety of the film roll transport device.

[0031] Furthermore, the frame 1 has an internal mounting plate 13, the drive motor 31 and the gearbox 34 are fixed to the same side bearing surface of the mounting plate 13, the mounting plate 13 has a transmission avoidance area 131, and the radial width of the transmission avoidance area 131 is greater than the pitch of the chain 36.

[0032] Specifically, such as Figure 2 As shown, the transmission avoidance zone 131 provides sufficient space for the chain 36, ensuring no interference in transmission, ensuring stable meshing between the chain 36 and the first gear 35 and the second gear 37, and ensuring that the drive assembly 3 can efficiently and stably drive the wheel assembly 4.

[0033] Preferably, a placement box 113 is fixedly installed on the outside of the mounting support portion 112, the placement box 113 has an upward opening, and the placement box 113 is used to place the battery 33.

[0034] like Figure 4 As shown, a placement box 113 is provided, and the battery 33 is placed in the placement box 113 from top to bottom. When it needs to be replaced, it is convenient for the operator to quickly take out the battery 33 for replacement, thereby improving the battery replacement efficiency.

[0035] Preferably, the limiting component 2 includes a mounting member 21, a limiting plate 22, a rotating shaft 23, and a limiting member 24. The mounting member 21 is provided on the opposite surfaces of the first support portion 11 and the second support portion 12. The two mounting members 21 are arranged opposite each other to form an installation area 211. Both ends of the rotating shaft 23 are fixed to the mounting member 21, and the rotating shaft 23 is located on the lower side of the installation area 211. The rotating end of the limiting plate 22 is rotatably connected to the rotating shaft 23. One end of the limiting member 24 is rotatably disposed on the mounting member 21, and the other end of the limiting member 24 can be locked onto another mounting member 21. The limiting member 24 is used to restrict the limiting plate 22 at the installation area 211. When the limiting plate 22 is restricted at the installation area 211, the non-rotating end of the limiting plate 22 protrudes from the installation area 211.

[0036] Specifically, such as Figure 2 As shown, when the film roll needs to be pushed onto the film roll transport device, the end of the limiting member 24 that is engaged is manually rotated and removed. The limiting plate 22 can be rotated around the pivot 23 away from the mounting area 211, thereby ensuring that the film roll can roll onto the first support part 11 and the second support part 12. After the film roll rolls onto the film roll transport device, the limiting plate 22 is rotated onto the mounting area 211 and rotated so that the limiting plate 22 is engaged with the mounting member 21. The limiting plate 22 is then restricted at the mounting area 211 and protrudes from the mounting area 211, thereby restricting the film roll between the limiting components 2 and limiting the rolling of the film roll in the width direction of the frame 1.

[0037] The rotation direction of the limiting member 24 is perpendicular to the rotation direction of the limiting plate 22, and the rotation direction of the limiting plate 22 is perpendicular to the rolling direction of the film roll. The force directions do not interfere with each other. The limiting plate 22 can better bear the inertial impact force of the film roll, avoid stress concentration, and at the same time ensure that when the operator operates the limiting component 2, the rolling of the film roll will not directly hit the operator's hand, thus improving the safety of operation.

[0038] Preferably, the mounting component 21 is provided with a limiting post, and the limiting component 24 is provided with an opening. When the limiting component 24 is rotated, the opening is locked onto the limiting post, thereby limiting the position of the limiting plate 22.

[0039] Preferably, the frame 1 is provided with a track 14, and the second support 12 can slide on the track 14; The second support portion 12 is provided with a positioning member 123 on the side away from the first support portion 11. The positioning member 123 can move up and down relative to the second support portion 12. The frame 1 is provided with a plurality of positioning grooves 15 corresponding to the positioning member 123. The plurality of positioning grooves 15 are located on the same straight line, and the straight line is parallel to the track 14.

[0040] like Figure 3 As shown, the second support part 12 moves on the track 14 and is inserted into the positioning groove 15 of the corresponding length of the film master roll by the positioning member 123, thereby ensuring that the first support part 11 and the second support part 12 can adapt to film master rolls of different lengths and improve transportation adaptability.

[0041] Preferably, the positioning element 123 is a pin.

[0042] Furthermore, the frame 1 is provided with two tracks 14, and the bottom ends of the second support part 12 are provided with sliders 124, and the two sliders 124 correspond to the tracks 14; The positioning element 123 is located in the middle of the second support part 12, and the positioning groove 15 is located between the two tracks 14.

[0043] Specifically, the tracks 14 on both sides, along with the positioning element 123 and positioning groove 15 in the middle, can ensure the stability of the movement of the second support 12, effectively avoid local stress, and adapt to the transportation needs of heavy film rolls.

[0044] Preferably, there are two positioning slots 15, and baffles 16 are provided on both sides of the positioning slots 15 away from the first support part 11, and the baffles 16 are fixed to the frame 1.

[0045] Specifically, the second support part 12 can correspond to two different lengths of film rolls. When the second support part 12 moves to the positioning groove 15 away from the first support part 11, the baffle 16 can provide certain support to the second support part 12, which can distribute the load and adapt to the transportation requirements of heavy film rolls.

[0046] Preferably, the control box 32, the drive motor 31, and the battery 33 are electrically connected via wires 38; The wire 38 is attached to the side wall of the frame 1 and the first support 11.

[0047] Specifically, the wires 38 are connected and are attached to the side wall of the frame 1, providing a certain support for the wires 38 and reducing the amount of maintenance work required to resolve the tangled wires 38.

[0048] Preferably, there are two wheel assemblies 4, and the two wheel assemblies 4 are located at the bottom of both ends of the frame 1.

[0049] Specifically, the two wheel assemblies 4 cooperate to support the frame 1, ensuring the stability of the frame 1 during movement.

[0050] The wheel assembly 4 further includes bearing seats 41 and rollers 43. The two bearing seats 41 are fixedly connected to the bottom sides of the frame 1. The two ends of the wheel axle 42 are rotatably connected to the bearing seats 41. The rollers 43 are fixedly connected to the wheel axle 42. The rollers 43 are located inside the bearing seats 41. The rollers 43 roll through the bearing seats 41 to meet the transportation needs of heavy master rolls. The rollers 43 are located inside the bearing seats 41, which effectively distributes the load and forms a certain physical isolation to avoid mechanical injury to operators when the heavy film master rolls are loaded, thus improving safety.

[0051] Preferably, the wheel assembly 4 includes two rollers 43, and the ground is provided with ground tracks corresponding to the rollers 43 to facilitate the movement of the film roll transport device.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
