[0033] To better explain and facilitate understanding of this utility model, the following description is provided in conjunction with the appendix. Figures 1-4 This invention will be described in detail through specific embodiments. Wherein, directional terms such as "upper" and "lower" mentioned herein are used in a specific manner. Figure 1 The orientation is used as a reference.

[0034] Example 1:

[0035] Reference Figures 1-4 An embodiment of this utility model provides an anti-winding caster, including a wheel body 1, a bearing 2, a bushing 3, a rotating shaft 4, and a first gantry frame 5. The wheel body 1 is rotatably connected to the rotating shaft 4 via the bearing 2. The two ends of the rotating shaft 4 are fixedly connected to two span-type connecting parts of the first gantry frame 5. The bearing 2 includes an inner bearing ring 21 and an outer bearing ring 22 nested together. An interval A is formed between the inner bearing ring 21 and the first gantry frame 5 on both sides of the axial direction of the wheel body 1. There are two bushings 3, both of which are sleeved on the rotating shaft 4. The bushings 3 are located in the interval A, and their two axial ends abut against the axial end face of the inner bearing ring 21 and the first gantry frame 5, respectively.

[0036] In this embodiment, since bushings 3 are provided in the interval A, with their two ends abutting against the inner ring 21 of the bearing and the first gantry 5 respectively, there will be a certain gap between the wheel body 1 and the wheel frame. Therefore, long, thin debris, including tobacco and hair, is less likely to get caught between the wheel body 1 and the first gantry 5. Furthermore, there will be no gap between the two ends of the bushings 3 and the inner ring 21 of the bearing and the first gantry 5. The inner ring 21 of the bearing remains stationary relative to the first gantry 5, so long, thin debris, including tobacco and hair, cannot come into contact with the shaft 4. Therefore, long, thin debris cannot get tangled around the shaft 4, thus greatly improving the reliability of the anti-tangling caster and its adaptability to environments containing long, thin debris. In this way, when the anti-tangling caster is used in cigarette cutting, rolling, and packaging workshops, tobacco and other debris that may be present in the factory area will not affect the normal use of the caster, indirectly improving cigarette production efficiency.

[0037] In other words, the shaft sleeve 3 abuts against the axial end face of the bearing inner ring 21 and the first gantry 5 respectively, which increases the width of the spacing area A, eliminates the possibility of foreign matter being clamped between the first gantry 5 and the wheel body 1, and eliminates the potential gap between the bearing 2 and the rotating shaft 4 and between the first gantry 5 and the rotating shaft 4, thereby ensuring the stationary state of the bearing inner ring 21 relative to the first gantry 5. Even if foreign matter tries to enter, it will be blocked by the close fit between the shaft sleeve 3 and the bearing inner ring 21. Long strip-shaped foreign matter cannot contact the rotating shaft 4 and thus cannot form a winding around the outer periphery of the stationary shaft sleeve 3.

[0038] The bearing 2 further comprises a cover 23 that closes the gap between the end faces of the bearing inner ring 21 and the bearing outer ring 22, which closes the gap between the bearing outer ring 22 and the bearing inner ring 21, reduces the probability of foreign matter entering the interior of the bearing 2, and further improves the use reliability of the caster.

[0039] The axial length of the shaft sleeve 3 is greater than 5 mm. By limiting the length of the shaft sleeve 3, the reliability of preventing long strip-shaped foreign matter from being clamped between the wheel body 1 and the first gantry 5 can be improved. By limiting the axial length of the shaft sleeve 3 to be greater than 5 mm, the reliability of preventing long strip-shaped foreign matter from being clamped between the wheel body 1 and the first gantry 5 can be further improved while ensuring that the caster still has a relatively compact size.

[0040] The outer periphery of the shaft sleeve 3 is an electroplated layer. The electroplated layer has the advantages of smoothness and corrosion resistance. By providing the electroplated layer, the probability of foreign matter adhering to the outer surface of the shaft sleeve 3 can be further reduced, thereby further improving the use reliability of the caster.

[0041] The bearing 2 can be provided in a symmetrical double arrangement to improve the structural stability of the caster.

[0042] Embodiment 2:

[0043] With reference to Figures 1-4 In addition to the above-mentioned technical solutions of the embodiments, the embodiments of the utility model further have the following technical solutions:

[0044] The anti-winding caster further comprises a second gantry 6, an elastic assembly 7, and a hinge shaft 8. The second gantry 6 is hinged to the first gantry 5 along a first axis through the hinge shaft 8 and straddles the first gantry 5. The first axis is parallel to the axis of the rotating shaft 4. The elastic assembly 7 is supported between the first gantry 5 and the second gantry 6. The part between the axis of the rotating shaft 4 and the first axis corresponds to the first gantry 5, which forms a power arm. The part between the first axis and the elastic assembly 7 corresponds to the first gantry 5, which forms a resistance arm. When the power arm swings upward, the resistance arm swings downward to deform the elastic assembly 7 to store energy and provide the resistance arm with an elastic force for downward swinging.

[0045] In this embodiment, the second gantry 6 is hinged to the first gantry 5 along the first axis and sits outside the first gantry 5, thereby providing the first gantry 5 with the freedom to swing along the first axis relative to the second gantry 6. Specifically, the two can be hinged through a hinge shaft 8.

[0046] The height of the hinge shaft 8 can be significantly higher than the height of the bottom tangent of the wheel body 1, avoiding long strip sundries from winding around the hinge shaft 8. Bearings 2 and shaft sleeves 3 of the same structural principle can also be provided on the hinge shaft 8 to achieve the purpose of preventing winding, and the two options can be used alone or simultaneously.

[0047] The elastic assembly 7 is supported between the first gantry 5 and the second gantry 6, playing a role in connection and support. When the power arm swings upward, the resistance arm will swing downward. At this time, the elastic assembly 7 will deform and store energy. When the power arm swings downward, the elastic assembly 7 will release the stored energy to provide the resistance arm with the elastic force for swinging downward. This design enables the caster to better absorb and release energy when subjected to external forces, improving the buffer performance and stability of the caster and ensuring the obstacle-crossing ability of the caster.

[0048] Since the second gantry 6 is hingedly connected to the first gantry 5, the caster can better adapt to different angles and position changes during rotation. This design improves the flexibility and adaptability of the caster, enabling it to work stably in more complex environments.

[0049] The elastic assembly 7 includes a compression spring 71, a pressing plate 72, and a pull rod 73. The first gantry 5 is fixedly connected with a first connecting seat 50, and the second gantry 6 is fixedly connected with a second connecting seat 60. The first connecting seat 50 is lower than the second connecting seat 60. The pull rod 73 penetrates and is slidingly connected to the first connecting seat 50 and the second connecting seat 60. The pressing plate 72 is fixedly connected to the top end of the pull rod 73. The compression spring 71 is sleeved on the pull rod 73 and has two ends abutting against the second connecting seat 60 and the pressing plate 72, respectively. The lower end of the pull rod 73 forms a limiting portion to limit the upward sliding of the pull rod 73 relative to the first connecting seat 50.

[0050] In this embodiment, when the power arm swings upward, it will drive the first gantry 5 to swing downward relative to the second gantry 6. At this time, the pull rod 73 will be subjected to a downward pulling force, thereby driving the pressing plate 72 to move downward together. In the process of the downward movement of the pressing plate 72, the compression spring 71 will be compressed and store energy. When the external force that makes the power arm swing upward disappears, the compression spring 71 will release the stored energy to push the pressing plate 72 and the pull rod 73 to move upward together, thereby providing the resistance arm with the elastic force for swinging upward, so as to buffer the vibration when the caster walks.

[0051] And, the elastic assembly 7 of such structure can be supported between the first gantry 5 and the second gantry 6, thus can be protected by the first gantry 5 and the second gantry 6, and the use reliability is improved. The elastic assembly 7 can be arranged in multiple groups along the axis direction of the hinge shaft 8, so as to improve the buffering balance and buffering effect of the elastic assembly 7.

[0052] The spring force of the elastic assembly 7 is pulled by the pull rod 73, so that the height of the elastic assembly 7 is higher, the elastic assembly 7 is farther away from the ground, the possibility of being affected by sundries on the ground is reduced, and the use reliability of the caster is improved.

[0053] The first connecting seat 50 and the pull rod 73 form a clearance B that meets the deflection of the pull rod 73, and since the movement track of the pull rod 73 is an arc, the clearance B can avoid the interference between the pull rod 73 and the first connecting seat 50 or the second connecting seat 60 when the pull rod 73 is pulled, and the use reliability of the elastic assembly 7 and the caster is improved.

[0054] The first gantry 5 corresponding to the part between the connecting seat and the first axis forms a resistance arm, and the length ratio of the power arm to the resistance arm is greater than 2:1 and less than 3:1.

[0055] By limiting the length ratio of the power arm to the resistance arm to be between 2:1 and 3:1, the spring in the elastic assembly 7 can correspond to a larger displacement of the wheel body 1 with a smaller compression amount, so that the wheel body 1 has sufficient buffering stroke while ensuring the compactness of the elastic assembly 7 and the caster, and the caster can better adapt to different working environments and requirements. Moreover, the ratio range is also conducive to maintaining the stability of the wheel body 1, so that the caster can perform well in environments that need to withstand large impacts or vibrations or in occasions that need to maintain high stability.

[0056] By setting the wheel body 1 as a polyurethane rubber-encased wheel, the wear resistance and the quietness of the wheel body 1 can be well balanced, and the overall performance of the caster is improved.

[0058] The embodiment of the utility model provides a cigarette factory working trolley, including carrier, vertical rotation component and the anti-winding caster in any embodiment, the anti-winding caster is fixedly connected on the carrier through vertical rotation component, and vertical rotation component and anti-winding caster constitute universal wheel, so the cigarette factory working trolley contains all beneficial effects in any embodiment, and here is not repeated.

[0059] Specifically, the carrier can be a material transport trolley, a worker's working trolley and the like.
