Description

Technical Field

[0001] This utility model relates to the field of fabric laying machine technology, and in particular to an anti-slip walking mechanism. Background Technology

[0002] In garment factories, fabric is laid flat on a cutting table using a fabric spreading machine for cutting. The fabric spreading operation requires a flat surface, thus necessitating a fabric spreading mechanism to transport the fabric.

[0003] Patent CN221396523U discloses a drive anti-slip mechanism for a fabric spreading machine. The design features dual drive wheels, providing multiple contact methods on the column and the first and second circular plates. The entire support platform is adjustable, facilitating changes in contact methods and replacement of the contact panels. The height of the side positioning plates is adjustable, increasing the pressure between the contact panels and the first and second circular plates to enhance friction. The dual drive wheels are independently contacted via the contact panels. When the lifting mechanism is activated, the overall height of the support platform is adjusted, disengaging it from the dual drive wheels, i.e., disengaging the rack from the column. Rotating the adjusting column causes the support plates to rise continuously under the action of the threaded engagement, further adjusting the height of the side positioning plates. This allows the contact panels to contact the area below the first and second circular plates, changing the contact method. Depending on the required friction coefficient, the contact panels can be simultaneously attached to the first and second circular plates and engaged with the rack on the column, providing different contact methods to prevent slippage of the dual drive wheels.

[0004] However, the existing drive anti-slip mechanism described above transmits power by matching the tooth gaps between the racks with the clearance between the column. However, due to the large gaps in the clearance matching, the racks cannot be completely limited, resulting in instability of the drive anti-slip mechanism during travel. Therefore, there is an urgent need for an anti-slip walking mechanism. Utility Model Content

[0005] In view of the current situation of the prior art, this utility model provides an anti-slip walking mechanism, which can effectively solve the problem that in the prior art, transmission is carried out by matching the tooth gap between the rack and the column gap, but because the gap of the gap is large, the rack cannot be completely limited, resulting in the instability of the driving anti-slip mechanism during the movement.

[0039] 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.

[0040] Reference Figures 1 to 7 The present invention provides an anti-slip walking mechanism, which includes a walking component 1 and a track 2.

[0041] The walking assembly 1 includes a frame 11, wheels 12 and a drive unit 13. The wheels 12 are rotatably mounted on the frame 11. The wheels 12 have at least one set of locking grooves 121 formed along their axial direction. Each set of locking grooves 121 includes a plurality of locking grooves 1211 that are equally spaced along the circumference of the wheel 12. The drive unit 13 is disposed on the frame 11 for driving the wheels 12 to rotate.

[0042] The track 2 is formed with at least one set of snap-fit ​​teeth 21 for engaging with the snap-fit ​​groove group 121, and the at least one set of snap-fit ​​teeth 21 engages with the at least one set of snap-fit ​​groove group 121 in a one-to-one manner.

[0043] The anti-slip walking mechanism provided by this utility model, by setting the walking component 1 and the track 2 and other components, in practical applications, firstly, the locking groove group 121 of the wheel 12 is locked one by one by the locking tooth group 21, and then the driving member 13 drives the wheel 12 to rotate, so as to drive the wheel 12 to move on the track 2. By locking the locking tooth group 21 and the locking groove group 121, there will be no problem of excessive gaps in the fit, and the locking tooth group 21 can be completely limited, so that the anti-slip walking mechanism is stable during the movement. By setting the locking tooth group 21 and the locking groove group 121 and other components, this utility model can completely limit the locking tooth group 21, so that the anti-slip walking mechanism is stable during the movement.

[0044] Similar to each of the snap-fit ​​groove groups 121 including multiple snap-fit ​​grooves 1211 distributed at equal angular intervals along the circumference of the wheel 12, each of the snap-fit ​​tooth groups 21 includes multiple snap-fit ​​teeth distributed at equal angular intervals along the circumference of the wheel 12. This part should not be construed as a limitation of the present invention.

[0045] To enhance the stability of the anti-slip walking mechanism during operation, at least two sets of engagement slots 121 are provided, each with a different shape for its corresponding slot 1211. One set of engagement slots 121 has a triangular-like radial cross-section along the wheel 12. The other set has a fan-like radial cross-section. In practical applications, by designing one set of engagement slots 1211 with a triangular-like radial cross-section and the other set with a fan-like radial cross-section, the engagement tooth assembly 21 and the engagement slot assembly 121 engage more tightly during engagement, resulting in greater stability of the anti-slip walking mechanism during operation.

[0046] To ensure greater stability and ease of manufacturing of the anti-slip walking mechanism during operation, at least two sets of locking groove groups 121 are provided, with each set of locking groove groups 121 having the same shape for its corresponding locking groove 1211. Five sets of locking groove groups 121 are provided. The radial cross-section of the locking groove 1211 corresponding to each locking groove group 121 along the wheel 12 is approximately triangular. Alternatively, the radial cross-section of the locking groove 1211 corresponding to each locking groove group 121 along the wheel 12 is approximately fan-shaped. The size of the locking groove 1211 corresponding to different sets of locking groove groups 121 varies. In practical applications, designing the corresponding slots 1211 of at least two sets of the snap-fit ​​slot groups 121 to have the same shape, and ensuring that the at least two sets of the snap-fit ​​slot groups 121 are connected to the snap-fit ​​tooth group 21 respectively, can make the anti-slip walking mechanism more stable during travel. The identical shape of the slots 1211 facilitates manufacturing. Designing the corresponding slots 1211 of different sets of the snap-fit ​​slot groups 121 to have different sizes makes the connection between the snap-fit ​​tooth group 21 and the snap-fit ​​slot group 121 more tight during the snap-fit ​​drive process, making the anti-slip walking mechanism more stable during travel.

[0047] To make the anti-slip walking mechanism more stable during movement, four wheels 12 are provided. Two wheels 12 are located on the drive shaft and two wheels 12 are located on the driven shaft. The drive shaft and driven shaft are respectively provided with transmission gears. The driving component 13 includes a worm gear structure 131, a chain 132 and a motor 133. The worm gear structure 131 is located on the frame 11 and connected to the transmission gear of the drive shaft. The chain 132 is sleeved on the transmission gear of the drive shaft and the transmission gear of the driven shaft. The motor 133 is located on the frame 11 and its driving end is connected to the worm gear structure 131 to drive the transmission gear of the drive shaft to move, so that the chain 132 drives the drive shaft and the driven shaft to move synchronously. In practical applications, the transmission gear of the drive shaft is first driven by the motor 133, which causes the chain 132 to drive the drive shaft and the driven shaft to move synchronously. The locking tooth group 21 engages with the locking groove group 121, and there will be no problem of excessive gaps in the fit. The locking tooth group 21 can be completely limited, so that the anti-slip walking mechanism is stable during the movement.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
