[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of the embodiments.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.
[0030] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0031] The roller combination mechanism in this application mainly improves the structure of the existing roller to organically combine the roller shaft and the roller, and prevents the roller from shifting during operation through the setting of the centering component and the guide component, thereby ensuring stability and accuracy during the transmission process.
[0032] See also Figure 1-Figure 2 The roller combination mechanism in the present invention has a main structure including a roller 1 and a roller shaft 2. The roller shaft 2 is installed through the inside of the roller 1, and a centering component and a guide component are provided between the roller shaft 2 and the roller 1.
[0033] Roller end plates 11 are connected to both ends of the drum, and a through hole 12 for the roller shaft 2 to pass through is provided in the center of the roller end plate 11. The guide assembly includes a guide block 3 connected to the roller end plate 11, and the centering assembly includes a centering piece 4 sleeved on the roller shaft 2. A guide centering groove 31 is provided on the guide block 3.
[0034] By nesting the centering piece 4 with the guide centering groove 31, the roller shaft 2 and the roller 1 can be combined. Through a simple and convenient roller combination mechanism, the transmission rotation requirements are met, and combined with the guide centering groove 31 and the centering guide of the centering piece 4, the roller 1 is effectively prevented from being offset during the rotation process, thereby ensuring the accuracy and stability of the transmission process to the greatest extent.
[0035] In one of the specific embodiments, based on the nesting of the centering piece 4 and the guide centering groove 31, the close connection between the guide block 3 and the roller end plate 11, and the sleeve connection of the centering piece 4 on the roller shaft 2, in order to ensure the connection between the roller shaft 2 and the roller 1, a connecting hole 32 is provided on the guide block 3, and the connecting hole 32 passes through the radial direction of the guide block 3. The centering piece 4 is provided with a mounting hole 41 corresponding to the connecting hole 32. By connecting the fastening bolt 33 between the mounting hole 41 and the connecting hole 32, the guide block 3 and the centering piece 4 can be connected into an integral structure, thereby realizing the connection between the guide block 3 and the centering piece 4 between the roller 1 and the roller shaft 2.
[0036] Specifically, the connecting hole 32 includes a transverse through hole, the mounting hole 41 includes a countersunk hole arranged on the centering piece 4, and the fastening bolt 33 is screwed through the connecting hole 32 and screwed into the mounting hole on the centering piece 4, thereby fastening the guide block 3 to the centering piece 4.
[0037] Furthermore, the fastening bolt 33 includes a flat cap bolt, which can facilitate the screwing operation. The external thread portion of the flat cap bolt extends into the connecting hole 32 and the mounting hole 41 to fix the roller shaft 2 and the roller 1 as a whole.
[0038] In another specific embodiment, the guide block 3 includes a guide cone arranged concentrically with the roller end plate 11. The guide cone is specifically a cone structure with regular thickness, and its side wall is tightly positioned and fixed to the roller end plate 11, thereby facilitating the connection and installation of the roller shaft 2 and the roller 1. Combined with the concentric arrangement of the guide cone and the roller end plate 11, it is convenient for the roller shaft 2 to pass through the center of the end of the roller 1.
[0039] The roller end plate 11 is connected to the inner side of the end of the roller 1. The guide block 3 and the centering piece 4 have the same thickness. The centering piece 4 and the guide block 3 are installed between the roller end plate 11 and the end opening of the roller 1 in a matching manner.
[0040] Furthermore, the thickness of the guide block 3 and the centering member 4 is smaller than the distance between the roller end plate 11 and the end opening of the roller 1, thereby reducing interference with other structures.
[0041] The centering piece 4 in this embodiment is detachably connected to the roller 2 as an integral structure. Specifically, the centering piece 4 includes a centering block with a centrally symmetrical structure, and the roller 2 is installed through the center of the centering piece 4. Furthermore, the guide centering groove 31 is opened in the center of the guide block 3, specifically a through groove structure that passes through the thickness direction of the guide block 3. Combined with the concentric arrangement of the guide cone and the end of the roller 1, the roller 2 can be installed on the axis of the roller 1.
[0042] The nested fit of the centering block and the guide centering groove 31 regulates the installation structure of the roller 1, ensuring coaxial installation between the roller 1 and the roller shaft 2. The centering assembly and the guide assembly form the anti-drift mechanism of the roller assembly, significantly reducing the deviation and vibration of the roller 1 during operation, extending the service life of the equipment while improving the stability and reliability of the production process. This, in turn, reduces downtime and maintenance costs, and improves production efficiency.
[0043] From the perspective of specific structural composition, the centering member 4 in the present invention is preferably a centering gear 4a connected to the end of the roller shaft 2. The centering gear 4a is preferably a centrally symmetrical star gear. The guide centering groove 31 includes a gear groove 31a that is snap-fitted with the centering gear 4a. The specific gear groove 31a is in the form of a through groove, which can stably and reliably nest the centering gear 4a in the gear groove 31a. It should be pointed out that based on the nesting fitting angle between the two, the fitting of the centering gear 4a and the gear groove 31a should minimize the gap between the two while ensuring that they can be separated from each other, thereby providing synchronization and reliability of the fit.
[0044] The centering assembly and the guide assembly are arranged in pairs, and each roller 1 includes two pairs of assemblies arranged at both ends of the roller 1. Based on the extension of the roller shaft 2 on the roller end plates 11 on both sides of the roller 1, the stability of the combination of the roller shaft 2 and the roller 1 can be ensured.
[0045] Further, combined with Figure 3 A central hollow tube 13 is provided inside the roller 1 , and the central hollow tube 13 can facilitate the rapid positioning and connection of the roller shaft 2 .
[0046] The two end openings of the central hollow tube 13 are respectively connected to the through hole 12. Furthermore, the diameter of the through hole 12 is the same as the diameter of the central hollow tube 13, and the diameter of the through hole 12 is larger than the outer diameter of the roller shaft 2 and smaller than the maximum diameter of the uncut part of the centering gear 4a, which can ensure the connection strength between the roller shaft 2 and the roller 1.
[0047] The interaction of the centering and guide components provides the roller assembly with an effective centering adjustment mechanism, limiting the sway and offset of roller 1, improving overall stability and ensuring precise horizontal and vertical alignment of roller 1, minimizing transmission efficiency degradation and equipment damage caused by offset. High-quality bearings and seals can be installed at both ends of roller shaft 2 to ensure roller 1 remains stable during operation.
[0048] This utility model adopts a modular design concept, making the roller assembly mechanism easy to assemble, disassemble, and maintain, reducing the technical skills required of technicians, shortening maintenance time, and lowering operating and maintenance costs. In addition, the modular design helps to standardize and universalize spare parts, further reducing inventory costs.
[0049] Lightweight and high-strength materials can be used during processing to reduce the overall weight. Lightweight materials make the transportation and installation of the equipment more labor-saving and improve the portability and flexibility of the equipment.
[0050] The present invention also provides a transmission assembly, including a transmission belt and the roller assembly mechanism. Based on the stable and reliable connection between the roller 1 and the roller shaft 2 provided by the roller assembly mechanism, efficient and stable transmission can be achieved via the transmission belt, which can be a synchronous belt, a flat friction transmission belt, a transmission chain, etc., to ensure accurate and efficient power transmission.
[0051] The transmission components can transmit more power or materials in the same amount of time, which directly improves the overall efficiency of the production line. Efficient transmission also means less energy loss, further saving energy costs.
[0052] The roller combination mechanism and transmission assembly in the present invention are designed to be simpler and more compact, thus reducing manufacturing costs and maintenance difficulties. During the design and manufacturing process, the mass distribution and geometric shape of the roller 1 are fully considered to ensure that it can maintain balance during operation and reduce vibration and offset. High-precision processing technology and high-quality materials are used to improve the manufacturing accuracy and service life of the roller combination mechanism, and reduce performance degradation due to wear. The structural setting is easy to install and debug, which reduces the difficulty of installation and debugging and improves work efficiency. Through reasonable structural design and material selection, the roller 1 is prevented from deviating up, down, left, and right during operation, ensuring the stability and reliability of the transmission efficiency.
[0053] By comparing the use process of the existing traditional pneumatic shaft, the roller combination mechanism in the present invention can significantly reduce the offset of the roller 1, and significantly improve the stability and reliability of the operation of the roller 1.
[0054] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.
[0055] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
