The deviation of the material belt may lead to inaccurate product processing, or even produce defective or waste products, causing economic losses to the production company.

[0003] In order to solve this problem, improve production efficiency and product quality, and meet the needs of actual production, it is necessary to deeply improve and optimize the existing guide wheel structure. Improving the design of the guide wheel structure so that it can better adapt to and guide the feeding of the material belt and reduce or eliminate the deviation phenomenon has become an urgent need for the current development of guide wheel technology.

[0034] A wheel body, the wheel body comprising a central axis 1 and an annular wheel 2 arranged around the central axis 1, the annular wheel 2 being provided with a groove 3 for guiding the conveying of the material belt;

[0035] A guide device, the guide device comprises a guide plate 4 and an adjustment mechanism, the guide plate 4 is sleeved on the groove 3 of the annular wheel 2 and is located on both sides of the groove 3, the adjustment mechanism is arranged in the inner cavity of the central shaft 1, and the adjustment mechanism is used to adjust the distance between the two guide plates 4;

[0036] The adjustment mechanism includes a driving motor and a threaded screw, the threaded screw is installed at the output end of the driving motor, an adjustment port 5 is arranged around the groove 3 of the central shaft 1 and the annular wheel 2, an adjustment ring 11 is sleeved on the threaded screw, an adjustment rod 12 is arranged around the adjustment ring 11, and the adjustment rod 12 passes through the adjustment port 5 and is connected to the guide plate 4.

[0037] The preferred solution of the above-mentioned novel guide wheel structure is:

[0038] Design of drive motor and screw rod:

[0039] Embodiment 1, dual-axis motor 8 solution: a dual-axis motor 8 is used as a driving source, and a forward screw 9 and a reverse screw are installed at the output ends on both sides. This design allows the screws on both sides to rotate independently, and through different rotation directions and speeds, the spacing between the two guide plates 4 can be accurately adjusted to adapt to material strips of different specifications and materials.

[0040] Embodiment 2, servo motor 13 and bidirectional screw 14 solution: A servo motor 13 is selected as a driving source, and its output end is connected to a bidirectional screw 14. The bidirectional screw 14 is provided with a reverse thread area and a forward thread area, and through the precise control of the motor, the bidirectional rotation of the screw can be realized, thereby adjusting the spacing between the two guide plates 4. The use of the servo motor 13 makes the adjustment more precise and stable.

[0041] Optimization of adjustment port 5 and guide structure:

[0042] Chamfered structure of the adjusting port 5: The side of the adjusting port 5 is designed as a chamfered structure, which not only facilitates the installation and adjustment of the guide plate 4, but also reduces the resistance of the conveying port to the material belt during the conveying process, thereby improving the conveying efficiency.

[0043] Design of guide plate 4 and annular groove 15: An annular groove 15 is provided inside the guide plate 4, and its side also adopts a chamfered structure. Such a design can increase the contact area between the guide plate 4 and the material strip, improve the guiding stability, and reduce the wear of the material strip.

[0044] Design of wheel body and groove 3:

[0045] The annular wheel 2 is sleeved and connected with bolts: the annular wheel 2 is sleeved on the central shaft 1 and connected with the central shaft 1 through a bolt structure. This connection method makes the annular wheel 2 easy to install and disassemble, and is convenient for maintenance and replacement.

[0046] Groove 3 and anti-slip pattern 6 design: The groove 3 on the wheel surface is used to guide the material belt to be transported, while the anti-slip pattern 6 surrounding the surface of the groove 3 increases the friction between the material belt and the material belt to prevent the material belt from slipping or deflecting during the transmission process.

[0047] The new guide wheel structure is mainly composed of a wheel body, a guide device and an adjustment mechanism. These components work together to achieve stable transmission and precise guidance of the material belt.

[0048] Wheel structure:

[0049] The wheel body is composed of a central shaft 1 and an annular wheel 2. The annular wheel 2 is arranged around the central shaft 1, and a groove 3 is provided on its surface to guide the transmission of the material belt. The surface of the groove 3 of the annular wheel 2 is surrounded by anti-skid grooves 6, which increase the friction between the material belt and the material belt to prevent the material belt from slipping or deflecting during the transmission process. The guide plate 4 is matched with the anti-skid grooves 6 through the guide grooves 7, so that the guide plate 4 is not blocked by the anti-skid grooves 6 during adjustment. The annular wheel 2 is fixed to the central shaft 1 by a bolt structure, which is convenient for installation and disassembly. Gears and chains can be installed at both ends of the central shaft 1 for transmission, or the ends of the central shaft 1 can be connected to the servo motor 13 through a coupling for driving.

[0050] Guide device:

[0051] The guide device includes a guide plate 4 and an adjustment mechanism. The guide plate 4 is sleeved on the groove 3 of the annular wheel 2 and is located on both sides of the groove 3 to clamp and guide the material strip. The adjustment mechanism is located in the inner cavity of the central shaft 1 and adjusts the spacing between the two guide plates 4 to accommodate material strips of different widths or thicknesses.

[0052] Adjustment mechanism:

[0053] The adjustment mechanism is the core part of the new guide wheel structure, which consists of a drive motor and a threaded screw. The drive motor generates power and drives the threaded screw to rotate through the output end. The threaded screw is sleeved with an adjustment ring 11, and an adjustment rod 12 is provided on the adjustment ring 11. The adjustment rod 12 passes through the adjustment port 5 on the central shaft 1 and the annular wheel 2 and is connected to the guide plate 4. When the threaded screw rotates, the adjustment ring 11 drives the adjustment rod 12 to move, thereby adjusting the position of the guide plate 4.

[0054] According to different preferred solutions, the design of the drive motor and the threaded screw is different:

[0055] In the dual-axis motor 8 solution, the two output ends are respectively equipped with a forward screw 9 and a reverse screw. By controlling the rotation direction and speed of the two screws, the positions of the two guide plates 4 can be independently adjusted to achieve accurate guidance of the material belt.

[0056] In the servo motor 13 and bidirectional screw 14 scheme, the driving motor is the servo motor 13, and the output end is connected to the bidirectional screw 14. The bidirectional screw 14 is provided with a reverse thread area and a forward thread area, and the bidirectional rotation and fine adjustment of the screw are realized through the precise control of the servo motor 13, so as to accurately adjust the position of the guide plate 4.

[0057] In addition, the side of the adjustment port 5 is designed as a chamfered structure, which facilitates the adjustment rod 12 to smoothly pass through and adjust the position of the guide plate 4. The annular groove 15 and the chamfered structure on the inner side of the guide plate 4 also play a similar role, increasing the guiding stability and reducing the wear of the material strip.

[0058] In summary, the new guide wheel structure achieves stable transmission and precise guidance of the material belt by optimizing the design of the wheel body, guide device and adjustment mechanism, effectively solves the problem of material belt deviation in the existing guide wheel structure, and improves production efficiency and product quality.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
