[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments of this application and the accompanying drawings.

[0043] like Figure 1 As shown, a motorcycle tire forming machine tire body feeding rack includes, in sequence according to the material movement direction: an inner liner feeding mechanism 1 and a sorting conveyor belt 3. At least one set of cord fabric feeding mechanisms 2 is provided on both sides of the sorting conveyor belt 3. The specific structure of the sorting conveyor belt 3 is the same as that of the traditional tire processing rubber sheet conveyor belt, and will not be described in detail here. The number and arrangement direction of the cord fabric feeding mechanisms 2 are not limited and can be flexibly adjusted according to factors such as the type of cord fabric material, the specific number of cord fabric layers required, and the size of the layout area. (Refer to...) Figure 7 , Figure 8 Two layout methods; in another specific embodiment, the structure of the sorting conveyor belt 3 can be single-layer or multi-layer, and there is no specific limitation.

[0044] The inner lining feeding mechanism 1 is used to provide the sorting conveyor belt 3 with a fixed-length cut inner lining layer 4;

[0045] The fabric feeding mechanism 2 is used to provide the sorting conveyor belt 3 with fabric layers 5 cut according to a pre-width and a pre-set angle;

[0046] The sorting conveyor belt 3 is used to sort and convey the inner lining layer 4 and the curtain layer 5 to the forming drum.

[0047] In one specific embodiment, the above-mentioned mechanisms and components are controlled by a control box, so that they cooperate with each other and work together. Furthermore, the parameters can be adjusted through the control box and external input devices to meet the needs of products with different specifications.

[0048] By directly providing pre-cut cord layers 5 of fixed length and at preset width and angle, the traditional feeding method eliminates the cutting-jointing-cutting process of the cord, avoiding the problem of joints being too close together due to joining. This ensures that each cord layer has only one joint, and all material joints are evenly distributed, improving the dynamic and static balance performance of the tire, enhancing high-speed driving comfort, and meeting the performance requirements of high-quality tires. Preferably, the width of the cord roll is the same as the length of the cord layer required for the forming drum. In this way, the cord feeding mechanism only needs to control the width of the cord layer 5, reducing processing steps and improving material utilization.

[0049] like Figure 1 and Figure 3 As shown, the fabric feeding mechanism 2 includes, in sequence according to the material movement direction: fabric guiding component 201 and fabric conveyor belt 202. A fabric cutting component 203 is arranged across the middle of the fabric conveyor belt 202, and a fabric transfer robot 205 is arranged above the end of the fabric conveyor belt 202.

[0050] The curtain guide assembly 201 is used to unfold the curtain roll and convey it to the curtain conveyor belt 202, which is used to convey the curtain.

[0051] The curtain cutting assembly 203 works in conjunction with the curtain conveyor belt 202 to cut the continuous curtain into independent curtain layers 5 according to a preset width and a preset angle, and to separate each independent curtain layer 5 by a certain distance.

[0052] The fabric transfer robot 205 is used to transfer the fabric layer 5 on the fabric conveyor belt 202 to the sorting conveyor belt 3, and to make the long side of the fabric layer 5 parallel to the length direction of the sorting conveyor belt 3.

[0053] The curtain opening assembly 201 automatically unfolds the curtain roll and conveys it to the curtain conveyor belt 202, realizing the automation and continuity of curtain supply. Then, the curtain conveyor belt 202 continues to convey the curtain, and the curtain cutting assembly 203 cuts the curtain synchronously during the stepping conveying process, reducing additional stops and manual intervention, and improving the automation level of the equipment.

[0054] When the cord fabric transfer robot 205 transfers the cord fabric layer 5 to the sorting conveyor belt 3, it ensures that the long side of the cord fabric layer 5 is parallel to the length direction of the sorting conveyor belt 3. This standardized placement method facilitates the accurate sorting and conveying of the subsequent inner liner layer 4 and cord fabric layer 5 on the sorting conveyor belt 3, ensuring the bonding sequence and positional accuracy of the materials on the forming drum, and further improving the forming quality of the tire.

[0055] like Figure 3 As shown, an angle adjustment component 204 is provided between the fabric cutting component 203 and the fabric conveyor belt 202. The angle adjustment component 204 is used to adjust the angle between the fabric cutting component 203 and the fabric conveyor belt 202 in the horizontal direction projection.

[0056] Different specifications of motorcycle tires may require different angles at both ends of the cord layer 5. The angle adjustment component 204 can flexibly adjust the angle between the cord cutting component 203 and the cord conveyor belt 202 in the horizontal direction, so that the cord can be cut at different preset angles. In this way, the tire body feeder of the forming machine can produce motorcycle tires of various specifications and with different cord angle requirements, improving the versatility of the equipment and its adaptability to diverse market demands.

[0057] like Figure 6 As shown, the angle adjustment component 204 includes: a mounting frame 2041 fixedly connected to the curtain conveyor belt 202, two annular guide rails 2042 fixedly connected to the mounting frame 2041, the two annular guide rails 2042 being distributed on both sides of the curtain conveyor belt 202, the two ends of the curtain cutting component 203 being slidably connected to the two annular guide rails 2042 respectively, and the annular guide rails 2042 being provided with locking components for locking the curtain cutting component 203.

[0058] Two annular guide rails 2042 are distributed on both sides of the fabric conveyor belt 202, and the two ends of the fabric cutting assembly 203 are slidably connected to them. This allows the fabric cutting assembly 203 to slide along the annular guide rails 2042. This sliding method allows for easy adjustment of the angle between the fabric cutting assembly 203 and the fabric conveyor belt 202 in the horizontal direction, meeting the requirements of different cutting angles for different tire specifications during production, thus enhancing the equipment's versatility and production flexibility. A locking component on the annular guide rails 2042 can reliably lock the fabric cutting assembly 203 onto the annular guide rails 2042 after it has been adjusted to a suitable angle. In one specific embodiment, the locking component can be a locking screw that cooperates with the fabric cutting assembly 203; the locking is achieved through the cooperation of the locking screw and the annular guide rails 2042.

[0059] like Figure 6 As shown, the annular guide rail 2042 is provided with a marking scale 2043. The marking scale 2043 provides the operator with an intuitive angle reference, avoiding errors caused by estimating the angle based on experience.

[0060] like Figure 1 As shown, the curtain fabric transfer robot 205 is equipped with a vision inspection component 6, which is used to detect whether the position and size of the curtain fabric layer 5 are accurate.

[0061] like Figures 4-5 As shown, the curtain fabric transfer robot 205 includes: a mounting base 2051 fixedly connected to the curtain fabric conveyor belt 202; a first turntable 2052 fixedly connected to the mounting base 2051; a working end of the first turntable 2052 fixedly connected to one end of a first extension arm 2053; a second turntable 2054 fixedly connected to the other end of the first extension arm 2053; a working end of the second turntable 2054 fixedly connected to one end of a second extension arm 2055; and a gripping component for gripping the curtain fabric layer 5 is provided at the lower part of the second extension arm 2055.

[0062] Through the coordinated action of the first turntable 2052 and the second turntable 2054, the angle of the gripping component can be precisely controlled. When gripping the ply, the angle of the gripping component can be matched with the placement angle of the ply 5, ensuring accurate gripping. When placing the ply 5 onto the sorting conveyor belt 3, it can be ensured that the long side of the ply 5 is parallel to the length direction of the sorting conveyor belt 3, meeting the strict requirements of the production process for the placement position and angle of the ply, thus improving the precision and quality of tire production. In one specific embodiment, the gripping component can be a vacuum suction cup assembly; the specific structure will not be described in detail here.

[0063] like Figure 2As shown, the inner liner feeding mechanism 1 includes: an inner liner guiding assembly 101, an inner liner cutting assembly 102, and an inner liner conveyor belt 103. The structure of the inner liner feeding mechanism 1 is similar to that of the inner liner feeding assembly in traditional tire molding, and the specific structure will not be described in detail here.

[0064] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
