Therefore, they should not be construed as limitations on this utility model.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] As attached Figure 1-4 The present invention discloses a bonding and positioning device for a three-drum forming machine, comprising: a through shaft 1, located on the frame plates 2 at the left and right ends, for supporting a rotating roller 3, a locking structure 5, a positioning structure 4 and the material to be bonded, the rotating roller 3 being sleeved outside the through shaft 1, and the rotating roller 3 being rotatably connected to the through shaft 1;

[0031] Positioning structure 4 is set on the through shaft 1, can rotate around the through shaft 1 and can be installed and positioned by positioning fasteners, and is used for positioning the tire crown belt fitting gap;

[0032] The locking structure 5 is set on the rotating roller 3 and the tire crown belt width is adjusted by axial adjustment along the direction of the through shaft 1.

[0033] Obviously, this application supports each component through the through shaft 1, the positioning structure 4 realizes the adjustment and fixation of the tire crown belt contact spacing, and the locking structure 5 realizes the adjustment in the width direction of the tire crown belt, thus realizing the tire contact positioning function with high precision, high efficiency and high adaptability, and solving the problems of inaccurate positioning, inconvenient adjustment and unstable structure in traditional equipment.

[0034] As an embodiment of this application, the left and right ends of the through shaft 1 are installed on the frame plate 2, and the number of through shafts 1 can be set to one or more. Those skilled in the art can make specific designs according to the fitting and installation requirements.

[0035] Further details are attached. Figure 1 and Figure 4 As shown, there are two through shafts 1, which are arranged parallel to each other. The two ends of the through shafts 1 are installed in the mounting holes on the frame plate 2 to achieve the fastening of the through shafts 1.

[0036] As an embodiment of this application, the frame plate 2 has a plate-shaped structure, and the frame plate 2 exhibits a continuous and smoothly transitioning arc from one end to the other in the direction perpendicular to the through shaft 1. The frame plate 2 adopts a design with a smooth transition arc, which not only enhances the mechanical properties of the overall structure, improves the load-bearing capacity and bending strength, but also optimizes the spatial layout, making the whole machine more compact and beautiful, and at the same time, it is conducive to stress dispersion and extends service life.

[0037] Furthermore, the frame plate 2 is provided with a first mounting hole and a second mounting hole. The frame plate 2 is connected and installed with other structural frames through the first mounting hole to achieve the support and fixation of the entire frame plate 2. The frame plate 2 is fixed to the through shaft 1 through the second mounting hole.

[0038] By setting multi-purpose mounting holes, the frame plate 2 achieves a stable connection with other structures and accurate positioning of the through shaft 1, which improves the assembly accuracy and structural stability of the entire device and enhances the overall rigidity and operational reliability of the system.

[0039] As an example of this application, see the attached document. Figure 1-2 As shown, the positioning structure 4 includes a positioning sleeve 41, which is detachably sleeved on the outside of the through shaft 1. The positioning sleeve 41 can move axially along the through shaft 1 by a preset distance for positioning the tire crown belt bonding spacing. By setting a detachable and axially movable positioning sleeve 41, the positioning structure 4 has higher flexibility and adaptability, making it easy to quickly adjust according to actual bonding requirements, thus improving the versatility and ease of operation of the equipment.

[0040] Furthermore, multiple positioning sleeves 41 are provided, and the multiple positioning sleeves 41 are symmetrically distributed along the centerline of the through shaft 1. The symmetrical distribution structure design helps to improve the balance and stability of the bonding process, avoid bonding deviations caused by uneven force, thereby improving the consistency of rubber product quality, and is particularly suitable for high-precision tire molding processes.

[0041] Furthermore, the positioning sleeve 41 is provided with multiple positioning holes 42, and positioning fasteners can be installed in the positioning holes 42. The positioning fasteners are used to fix the positioning sleeve 41, thereby realizing the positioning of the tire crown belt fitting distance.

[0042] Furthermore, positioning sleeves 41 are provided at the ends of the rotating rollers 3, with two positioning sleeves 41 provided for each rotating roller 3. Positioning sleeves 41 are provided at both ends of each roller, realizing bidirectional limiting of the material bonding area, further improving bonding accuracy and positioning reliability, and is especially suitable for tire manufacturing scenarios that require high degree of symmetry bonding.

[0043] As an embodiment of this application, the locking structure 5 includes a locking sleeve 51 and a locking fastener. The locking sleeve 51 is fixed to the rotating roller 3 by the locking fastener, and the locking sleeve 51 is an annular structure with a hollow center. The annular locking sleeve 51 has a reasonable structural design, which does not affect the rotation of the roller, and can achieve rapid adjustment and locking in the width direction through axial movement, simplifying the operation process and improving the response speed and adaptability of the equipment.

[0044] Furthermore, each through-shaft 1 is equipped with multiple rotating rollers 3, and each rotating roller 3 is equipped with zero or more locking sleeves 51. The configuration of multiple rotating rollers 3 and locking sleeves 51 expands the application range of the device, enabling it to process multiple bonding tasks or materials of different widths simultaneously, significantly improving equipment utilization and production efficiency, and making it suitable for batch production.

[0045] As attached Figure 3 As shown, the rotating roller 3 has cylindrical holes arranged in a stepped pattern. The diameter of the first cylindrical hole near the opening of the rotating roller 3 is larger than the diameter of the second cylindrical hole inside the rotating roller 3, while the height of the first cylindrical hole is much smaller than the height of the second cylindrical hole. For example, the first cylindrical hole has a diameter of 21 mm and a height of 6 mm; the second cylindrical hole has a diameter of 17 mm and a height of 322 mm. The size of the second cylindrical hole matches the through shaft 1, and the size of the first cylindrical hole is used for fixing the end of the rotating roller 3. It is readily understood that those skilled in the art can select and design the structure and size of the rotating roller 3 according to the dimensions of the through shaft 1.

[0046] For example, see attached Figure 1As shown, the through-shaft 1 includes a first through-shaft 11 located at the top and a second through-shaft 12 located at the bottom. The first through-shaft 11 is equipped with two rotating rollers 3, each with zero locking sleeves 51. Similarly, the second through-shaft 12 is equipped with two rotating rollers 3, each with two locking sleeves 51. Through the arrangement of the first through-shaft 11, the second through-shaft 12, the rotating rollers 3, and the locking sleeves 51, under tension, the tire completes its initial positioning under the action of the first through-shaft 11, its rotating rollers 3, and the positioning sleeve 41, thus achieving the positioning of the tire crown belt contact distance. Then, under the action of the second through-shaft 12, its rotating rollers 3, the positioning sleeve 41, and the locking sleeve 51, while ensuring the positioning of the tire crown belt contact distance, the locking sleeves 51 are used to adjust and determine the crown belt width.

[0047] It should be noted that the positions of the positioning sleeve 41 and the locking sleeve 51 can be adjusted according to the specifications of the actual material to be bonded. This not only enables the tire rubber to be stretched and bonded securely, but also enables its precise positioning, allowing the material to be bonded to be positioned on the rotating roller 3 for bonding and positioning, avoiding damage to the shaft 1 due to stress, and simplifying the operation process.

[0048] Compared with the prior art, the above embodiments of this application have the following beneficial technical effects:

[0049] (1) Through reasonable structural design, this utility model realizes high precision, high efficiency and high adaptability of tire fitting and positioning function, and solves the technical problems of inaccurate positioning, inconvenient adjustment and unstable structure in traditional equipment;

[0050] (2) A rotating roller 3 is installed on the left and right sides of the through shaft 1 to improve the strength of the middle through shaft 1, reduce the bending deformation of the through shaft 1 under the action of cylinder force, improve the stability of the structure, and the length of the rotating roller 3 meets the maximum inner spacing requirement of the crown belt. The crown belt spacing adjustment range is expanded, and the minimum inner spacing can be reduced by 20 mm compared with the original structure to meet more tire specification requirements.

[0051] (3) A positioning sleeve 41 for determining the crown band fitting distance is provided on the through shaft 1, and a locking sleeve 51 for adjusting the crown band width is provided on the rotating roller. The device directly locks the crown band fitting inner distance, without frequently adjusting the positioning fixing parts on the through shaft 1. When adjusting, only the locking sleeve 51 needs to be adjusted to determine the crown band width. The adjustment process is simple and easy to operate.

[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
