Abstract
Description
Technical Field
[0001] This utility model relates to the field of material conveying technology, and in particular to an unwinding device. Background Technology
[0002] Currently, paper and film materials are mostly wound into rolls for storage and transportation to reduce volume and facilitate storage and transport. However, during production and use, the paper and film materials transported on rolls need to be gradually unwound and fed into the processing device. This unwinding and conveying process is called the unwinding process.
[0003] In existing unwinding processes, the material roll (i.e., the paper, film, etc. transported on the roll) is often first loaded onto the unwinding assembly located at the front end of the processing device, and then the material roll is unwound by the unwinding assembly. Because the material roll is heavy and has a large axial dimension after being rolled, transportation and installation are difficult, which is not conducive to improving production efficiency and reducing labor intensity.
[0004] Therefore, there is an urgent need for an unwinding device to solve the above-mentioned technical problems. Utility Model Content

[0035] The following is based on the appendix Figure 1 This invention introduces the unwinding device provided by this utility model.
[0036] Specifically, the unwinding device includes a frame 1, a mounting base 2, a mounting shaft 3, a positioning component, and a drive component. The mounting shaft 3 is rotatably mounted to the frame 1 via the mounting base 2 and serves to fix the material roller 100, thus allowing the material roller 100 to be rotatably positioned. The drive component is fixedly connected to the positioning component and is drively connected to the mounting shaft 3, thereby driving the mounting shaft 3 to rotate, thus unwinding the material roller 100 and feeding the material into the processing device. Simultaneously, the drive component can also be separated from the mounting shaft 3, allowing the material roller 100 to be fitted and mounted onto the mounting shaft 3. Of course, when the drive component is separated from the mounting shaft 3, the material roller 100 can also be detached from the mounting shaft 3.
[0037] Continue to refer to Figure 1As shown, the bottom of the frame 1 is equipped with rollers 12, allowing the frame 1 to move. Simultaneously, the positioning component and the processing device are fixedly arranged relative to each other, thereby limiting and fixing the frame 1. This ensures that after movement, the frame 1, through the positioning component, achieves a relatively fixed state with the processing device. At this point, simply unfolding the material roller 100 allows material to be input into the processing device, ensuring the smooth implementation of the processing process.
[0038] The unwinding device allows the material roller 100 to be installed and moved as needed, and can be accurately positioned with the processing device. This enables the installation and replacement of the material roller 100 to be carried out under more favorable conditions by moving the frame 1. This not only facilitates the use of auxiliary tools for hoisting and transporting installation, but also greatly improves the convenience and efficiency of installation, reduces labor intensity, and reduces the possibility of interference and collision with the processing device during installation and replacement, thereby improving the safety of installation and replacement.
[0039] Specifically, in this embodiment, the frame 1 includes multiple longitudinal beams and multiple transverse beams, which are fixedly connected. When the material roller 100 is installed on the mounting shaft 3, transverse beams are provided around the material roller 100 in the horizontal direction, thereby protecting the material roller 100. At the same time, the positioning component can also abut against the transverse beams, thereby facilitating positioning after the frame 1 is moved.
[0040] like Figure 1 As shown, the frame 1 includes 4 longitudinal beams and 8 transverse beams. The 4 longitudinal beams extend vertically, and of the 8 transverse beams, 4 extend horizontally in a first direction and 4 extend horizontally in a second direction. The vertical, first, and second horizontal directions are perpendicular to each other. The longitudinal and transverse beams are fixedly connected, forming a cuboid frame structure. When the material roller 100 is mounted on the mounting shaft 3, at least a portion of the material roller 100 is located inside the cuboid frame structure. This provides protection for the material roller 100 through the transverse and longitudinal beams, preventing damage to the material roller 100 during the movement of the frame 1.
[0041] Preferably, the mounting shaft 3 is a keyed air shaft, and the two ends of the air shaft are connected to bearings through the air shaft matching safety clamp 31. The bearings are detachably mounted to the frame 1 through the mounting base 2, thereby fixing the mounting shaft 3 and the frame 1 and ensuring the stability when supplying materials.
[0042] Specifically, the frame 1 has a first groove, and the mounting base 2 has a second groove. When the mounting base 2 is detachably connected to the frame 1, the first and second grooves define an installation space, which can fix the bearing within the installation space. The mounting base 2 is connected to the frame 1 by bolts, so when the material roller 100 needs to be installed or removed, the bolts can be removed to separate the mounting shaft 3 from the frame 1, thus facilitating the installation and removal of the material roller 100.
[0043] A transmission component is mounted on one end of the mounting shaft 3, which is used for a detachable transmission connection with the drive assembly. Exemplarily, in some embodiments, a driven gear 32 is detachably mounted on the end of the mounting shaft 3, and the drive assembly includes a driving gear 51. Once the frame 1 is positioned, the driven gear 32 meshes with the driving gear 51 to transmit power. When the material roller 100 needs to be replaced, the driven gear 32 can be removed, thereby decoupling the drive assembly and the mounting shaft 3. This allows the frame 1 to be moved to a suitable replacement position without affecting the drive assembly.
[0044] Preferably, in this embodiment, the drive assembly includes a first drive member 52, a second drive member 53, and a drive gear 51. Both the first drive member 52 and the second drive member 53 are tractively connected to the drive gear 51. The first drive member 52 drives the drive gear 51 to rotate, and when the drive gear 51 meshes with the driven gear 32, it drives the driven gear 32 and the mounting shaft 3 to rotate. The second drive member 53 drives the drive gear 51 to move in directions approaching and away from the driven gear 32, thus enabling a detachable connection between the drive gear 51 and the driven gear 32 without removing the driven gear 32.
[0045] Specifically, in this embodiment, the drive assembly includes a support frame 55 and a swing arm 54. The support frame 55 is fixedly connected to at least one of the frame body 1 and the positioning assembly. The swing arm 54 is rotatably mounted on the support frame 55. A first drive member 52 is fixedly mounted on the swing arm 54. A drive gear 51 is rotatably mounted on one end of the swing arm 54 near the driven gear 32 and is drive-connected to the first drive member 52. A second drive member 53 is fixedly disposed and drive-connected to the swing arm 54. Under the action of the second drive member 53, the swing arm 54 can swing in the direction of approaching and moving away from the driven gear 32, thereby changing the distance between the drive gear 51 and the driven gear 32, so that the drive gear 51 and the driven gear 32 switch between a meshing state and a disengaged state.
[0046] Preferably, the first driving member 52 is fixedly mounted on the end of the swing arm 54 away from the driven gear 32, and the support frame 55 is rotatably connected to the center of gravity of the swing arm 54. A transmission belt 57 connects the first driving member 52 and the driving gear 51. This arrangement makes the weights at both ends of the swing arm 54 similar, thereby reducing the load requirements on the second driving member 53. Exemplarily, in this embodiment, both the first driving member 52 and the second driving member 53 are motors. The first driving member 52 is connected to the driving gear 51 via a reducer, a synchronous pulley 56, and a transmission belt 57, while the second driving member 53 is directly hinged to the swing arm 54.
[0047] Continue to refer to Figure 1 As shown, the positioning assembly includes a first positioning beam 41 and a second positioning beam 42, both of which are arranged horizontally. Specifically, the first positioning beam 41 is arranged along a first horizontal direction, and the second positioning beam 42 is arranged along a second horizontal direction, perpendicular to each other. Both the first positioning beam 41 and the second positioning beam 42 are fixedly positioned relative to the processing device. When the frame 1 moves, it simultaneously abuts against the first positioning beam 41 and the second positioning beam 42, maintaining a preset distance from the processing device, thus facilitating material supply. Preferably, in this embodiment, the positioning assembly includes two first positioning beams 41 and one second positioning beam 42, which together form a receiving space, capable of limiting and accommodating the frame 1, thereby further facilitating the positioning of the frame 1.
[0048] In this embodiment, the positioning assembly further includes a support member 43 and a support drive member 44. The support drive member 44 is fixedly disposed relative to the processing device, and the support member 43 is tractively connected to the support drive member 44. The support member 43 is vertically adjustable. When the frame 1 moves and maintains the aforementioned preset distance from the processing device, the support drive member 44 drives the support member 43 to rise, so that the support member 43 can abut against and fix the frame 1, thereby achieving the positioning of the frame 1. Preferably, the positioning assembly includes four support members 43 and four support drive members 44. Each support drive member 44 is tractively connected to one support member 43, and each support member 43 can abut against one corner of the frame 1, thereby smoothly lifting the frame 1, separating the roller 12 from the ground, and fixing the frame 1.
[0049] Optionally, in some embodiments, the support drive member 44 is fixedly installed at the bottom of the frame 1, and the support member 43 is tractively connected to the support drive member 44, and the position of the support member 43 is adjustable in the vertical direction. When the frame 1 moves and maintains the aforementioned preset distance from the processing device, the support drive member 44 drives the support member 43 to descend, so that the support member 43 can abut against the ground and fix the frame 1, thereby achieving the positioning of the frame 1.
[0050] Specifically, when using this unwinding device, first separate the mounting base 2 and remove the safety clamp 31 of the air shaft to separate the air shaft from the frame 1. Then, deflate the air shaft and insert it into the material roller 100. After insertion, pressurize with high-pressure gas to lock the air shaft and fix it to the material roller 100. Subsequently, move the air shaft and material roller 100 together onto the frame 1, and fix the air shaft, material roller 100, and frame 1 together using the safety clamp 31 and mounting base 2. After fixing, the frame 1 can be moved to abut against the first positioning beam 41 and the second positioning beam 42, so that the frame 1 is in a suitable position that maintains a preset distance from the processing device. Then, lift the support member 43 to separate the roller 12 from the ground, thus fixing the frame 1. After fixing, the position of the drive gear 51 is adjusted by the second drive component 53 so that the drive gear 51 and the driven gear 32 mesh, thereby realizing the normal unfolding of the material roller 100.
[0051] When the material roller 100 needs to be replaced, simply readjust the position of the drive gear 51 to separate the drive gear 51 from the driven gear 32, and lower the support member 43 so that the roller 12 re-contacts the ground, thus pushing the frame 1 away from the processing device. After moving away, repeat the above process of separating the air shaft from the frame 1 to remove the material roller 100 from the air shaft and replace it.
