[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0024] See attached Figures 1 to 9As shown, the present invention discloses a belt layer transfer ring 1, which is used to transfer a belt layer assembly (not shown) from a belt drum (not shown) to a forming drum (not shown). The belt layer transfer ring 1 includes a belt ring body 10, and the belt ring body 10 has an annular first end face 11 and a second end face 12, and the first end face 11 and the second end face 12 of the ring body form a receiving space 13, and a plurality of swing arm rotating shafts 14 are evenly arranged on the circumference of the first end face 11 of the ring body, and a plurality of arc grooves 121 are arranged on the second end face 12 of the ring body, and the plurality of arc grooves 121 are evenly distributed along the circumference of the second end face 12 of the ring body; the plurality of arc grooves 121 are rotatably arranged on the second end face 12 of the ring body through the moving part 20. The mounting plate 30 on the second end face 12 of the ring body is annular, and a plurality of connecting rod rotating shafts 31 are evenly arranged on the circumference of the mounting plate 30; it also includes a plurality of connecting rod assemblies 40 arranged in the accommodating space 13, and the connecting rod assembly 40 has a connecting rod first end 41, a movable connecting rod second end 42 and a connecting rod third end 43, wherein the connecting rod first end 41 is hinged with the swing arm rotating shaft 14, and the connecting rod first end 41 is rotatably arranged on the belt tie ring body 10 through the swing arm rotating shaft 14 The end of the connecting rod rotating shaft 31 away from the mounting plate 30 passes through the arc groove 121 on the second end surface 12 of the ring body and is hinged to the second end 42 of the connecting rod. The second end 42 of the connecting rod is rotatably arranged on the mounting plate 30 through the connecting rod rotating shaft 31. The third end 43 of the connecting rod is hingedly provided with a clamping block assembly 50. The clamping block assembly 50 has a clamping block 51 and a detachable connecting piece 52 and a limiting shaft 53 arranged on the clamping block 51. The shaft 53 forms an approximately circular structure C connected end to end for clamping, picking up, placing and transferring the belt layer assembly; it also includes a telescopic drive source 60, which is fixedly arranged on the belt ring body 10, and the driving end of the telescopic drive source 60 is fixedly connected to the mounting plate 30. The telescopic drive source 60 is used to drive the mounting plate 30 to move, thereby driving the second ends 42 of the connecting rods to move relative to the first ends 41 of the connecting rods, and then driving the third ends 43 of the connecting rods to move, thereby realizing the synchronous movement of the plurality of clamping block assemblies 50. The swing arm rotary shaft 14, the connecting rod rotary shaft 31, the connecting rod assembly 40 and the clamping block assembly 50 described in the present invention are consistent in number.

[0025] like Figure 2 , Figure 4 and Figure 6As shown, through the above arrangement, when the driving end of the telescopic driving source 60 is extended, the telescopic driving source 60 drives the mounting plate 30 to rotate counterclockwise on the belt ring body 10, and the mounting plate 30 drives a plurality of connecting rod rotating shafts 31 arranged thereon to synchronously move toward the direction close to the swing arm rotating shaft 14, and drives the second end portion 42 of the connecting rod to move toward the direction close to the first end portion 41 of the connecting rod, so that the distance between the third end portion 43 of the connecting rod and the center C1 of the approximately circular structure connected end to end formed by a plurality of clamping block assemblies 50 (the center C1 of the approximately circular structure coincides with the center position of the forming drum and the belt drum, that is, the approximately circular structure formed by the belt layer transfer ring is colinear with the axis of the forming drum and the belt drum) becomes smaller, that is, a plurality of connecting rod third ends 43 are connected to the connecting rod third ends 43, and the distance between the connecting rod third ends 43 and the center C1 of the approximately circular structure connected end to end formed by a plurality of clamping block assemblies 50 is shortened. The diameter of the approximately circular structure C formed by the clamping block assembly 50 with three ends 43 hinged is reduced; when the driving end of the telescopic driving source 60 is retracted, the telescopic driving source 60 drives the mounting plate 30 to rotate in the clockwise direction on the belt ring body 10, and the mounting plate 30 drives the plurality of connecting rod rotating shafts 31 arranged thereon to move synchronously in the direction away from the swing arm rotating shaft 14, and drives the second end 42 of the connecting rod to move in the direction away from the first end 41 of the connecting rod, so that the distance between the third end 43 of the connecting rod and the center C1 of the approximately circular structure formed by the plurality of clamping block assemblies 50 connected end to end is increased, that is, the diameter of the approximately circular structure C formed by the plurality of clamping block assemblies 50 hinged to the third end 43 of the connecting rod is increased. Therefore, the belt transfer ring 1 of the present invention rotatably sets the mounting plate 30 on the belt ring body 10 through the moving component 20, and when the mounting plate 30 moves, it can drive the plurality of connecting rod assemblies 40 to move synchronously, thereby realizing the synchronous movement of the clamping block assembly 50. The belt layer transfer ring described in the present invention can achieve synchronous movement of several clamping block assemblies 50 driven by the same telescopic driving source by setting a rotatable mounting plate 30 and a connecting rod assembly 40. The approximately circular structure connected end to end formed by several clamping block assemblies 50 can ensure the clamping accuracy of several clamping block assemblies 50, and will not clamp the belt layer assembly off-center or deform it, thereby ensuring the molding quality of the tire. In addition, by driving the movement of several clamping block assemblies 50 by the same telescopic driving source, the equipment cost can be greatly reduced.

[0026] like Figure 8As shown, the clamping block 51 of the present invention has a clamping block working surface 510, and the clamping block working surface 510 refers to a surface in contact with the belt layer assembly. The clamping block working surface 510 is arc-shaped. In the process of the clamping block 51 clamping and transferring the belt layer assembly, the clamping block working surfaces 510 of several clamping blocks 51 contact the belt layer assembly for clamping. And the more the number of clamping blocks 51, the closer the approximate circular structure formed by the arc-shaped working surfaces of several clamping blocks 51 is to the ideal circle, and the higher the clamping accuracy of the belt layer assembly. The accompanying drawings of the present invention only illustrate 17 clamping blocks 51, and the actual number of clamping blocks 51 can be set as needed.

[0027] like Figure 3 As shown, preferably, the moving component 20 described in the present invention is a combination of an arc-shaped slide rail 21 and a slider 22. By setting the arc-shaped slide rail 21 and the slider 22, the approximately circular structure C connected end to end formed by the clamping block assembly 50 has higher precision and can better clamp the belt layer assembly (not shown) to ensure the subsequent tire size.

[0028] like Figure 7 As shown, the clamping block 51 has a first clamping block inclined surface 511 and a second clamping block inclined surface 512 that are arranged opposite to each other, the connecting member 52 is detachably arranged at the first clamping block inclined surface 511, the limiting shaft 53 is arranged above the second clamping block inclined surface 512, the connecting member 52 has a connecting first end 521 and a connecting second end 522, the connecting first end 521 is detachably arranged at the first clamping block inclined surface 511, the connecting second end 522 is arranged through the limiting space formed by the limiting shaft 53 of the adjacent clamping block assembly 50 and the second clamping block inclined surface 512, so that a plurality of clamping blocks 51 and the connecting member 52 form an approximately circular structure C connected end to end. It should be noted that the distance between the limiting shaft 53 and the second clamping block inclined surface 512 is greater than the thickness of the connecting member 52, so that the connecting member 52 can pass through the limiting space formed by the limiting shaft 53 and the second clamping block inclined surface 512. Figure 5 As shown, the following description is made by taking the adjacent clamping block assemblies 50A and 50B as an example. Specifically, the clamping block assembly 50A includes a clamping block 51A, a connecting member 52A and a limiting shaft 53A arranged on the clamping block 51A, and the clamping block assembly 50B includes a clamping block 51B, a connecting member 52B and a limiting shaft 53B arranged on the clamping block 51B. One end of the connecting member 52A is arranged on the clamping block 51A, and the other end of the connecting member 52A passes through the space defined by the limiting shaft 53B and the clamping block 51B on the adjacent clamping block assembly 50B.

[0029] like Figure 4 and Fig. 9As shown, the first inclined surface 511 of the clamping block and the second inclined surface 512 of the clamping block of the present invention form the same angle with the horizontal plane, and the angle is a. By relatively setting the first inclined surface 511 of the clamping block and the second inclined surface 512 of the clamping block, and the first inclined surface 511 of the clamping block and the second inclined surface 512 of the clamping block form the same angle with the horizontal plane, when the first connecting end 521 of the connecting member is set at the first inclined surface 511 of the clamping block, the second connecting end 522 is placed on the second inclined surface 512 of the clamping block adjacent thereto, so that the connecting member 52 is located on the tangent of the approximately circular structure C, and a plurality of connecting members 52 form an circumscribed regular polygon of the circle, wherein one end of the side of the polygon protrudes from the polygon setting. Through the above-mentioned setting, the synchronization of the plurality of clamping block assemblies 50 is better when moving, and the precision of the formed approximately circular structure C is higher.

[0030] It should be noted that, although the clamping accuracy of the belt layer assembly is higher when the number of clamping blocks 51 is larger, since several clamping blocks 51 are connected end to end through the connecting piece 52 to form an approximately circular structure, the more the number of clamping blocks 51 is, the higher the coordination requirements between the clamping blocks 51 are. When the clamping blocks 51 are clamping the belt layer assembly, if the manufacturing accuracy of the clamping blocks 51 is not high and the coordination between several clamping blocks 51 is not good, jamming may easily occur. Therefore, in order to solve the above technical problems, Figure 7 Preferably, the connecting piece 52 described in the present invention is a sheet-like structure, and the connecting piece 52 can slide on the first inclined surface 511 of the clamping block adjacent to it, and is limited by the limiting axis 53 at the same time, so that the plurality of clamping blocks 51 have a certain amount of space for movement during the process of synchronously moving together and contracting or moving apart and expanding, and the plurality of clamping blocks 51 and the connecting piece 52 are not prone to jamming.

[0031] like Figure 6 As shown, the connecting rod assembly 40 of the present invention includes a first connecting rod 44 and a second connecting rod 45 which are hingedly arranged. Preferably, the second connecting rod 45 is arranged at the middle position of the first connecting rod 44, so that when a plurality of clamping block assemblies 50 move to change the diameter of the approximately circular structure C, the first end 41 of the connecting rod and the second end 42 of the connecting rod can achieve the same effect by moving a smaller distance, which is conducive to reducing the size of the entire belt layer transfer ring. Furthermore, the first end 41 of the connecting rod and the third end 43 of the connecting rod of the connecting rod assembly are not arranged in a colinear manner, which can further reduce the size of the entire belt layer transfer ring.

[0032] The belt transfer ring of the present invention usually clamps the annular belt assembly attached to the belt drum from the belt drum and transfers it to the subsequent forming process. Specifically, a plurality of clamping blocks 51 are synchronously contracted to contact the surface of the belt assembly, and the belt drum is contracted to no longer support the belt assembly, thereby clamping it. Figure 7 and Figure 8 As shown, in order to better achieve the fixed clamping of the belt layer assembly, the clamping block assembly 50 of the present invention also includes a needle 54, which is detachably arranged on the clamping block 51, and the needle 54 protrudes from the clamping block working surface 510, that is, the needle 54 protrudes from the side of the clamping block 51 that contacts the belt layer assembly. The detachable arrangement makes it easy to replace the needle 54 and adjust the length of the needle 54. By arranging the needle 54, and the needle 54 protruding from the clamping block working surface 510, when several clamping blocks 51 are synchronously contracted to contact the surface of the belt layer assembly, the needle 54 will penetrate into the belt layer assembly to fix the belt layer assembly, thereby better grasping and transferring the belt layer assembly.

[0033] The belt layer assembly described in the present invention is formed by composite lamination or winding of a belt layer, a cap layer and a tread layer, and the formed belt layer assembly has a joint. The belt layer transfer ring described in the present invention also includes a joint press 70, and the joint press 70 is arranged on the working surface 510 of the clamping block so as to crimp the joint of the belt layer assembly. The joint press 70 has a plurality of teeth 71, and when a plurality of clamping blocks 51 are synchronously contracted and contact the belt layer assembly, the joint of the belt layer assembly is squeezed by the teeth 71 on the joint press, and the contact area between the joint press 70 and the belt layer assembly is reduced by the structure of the teeth 71, thereby increasing the pressure at the contact position and better crimping the joint of the belt layer assembly. The joint press 70 can be arranged on the clamping block 51 at the joint of the belt layer assembly as needed.

[0034] Optionally, the belt transfer ring described in the present invention can be moved as a whole by a linear guide rail (not shown). After the belt transfer ring fixes and clamps the belt layer assembly, the belt transfer ring is moved to a specified position by the linear guide rail to transfer the belt layer assembly.

[0035] The working principle of the belt layer transfer ring described in the present invention is as follows: when the belt layer transfer ring needs to clamp, wrap or adhere to the belt layer assembly on the belt drum, the telescopic driving source 60 drives the mounting plate 30 to rotate, so that the second ends 42 of the connecting rods move synchronously in the direction away from the first ends 41 of the connecting rods, driving the third ends 43 of the connecting rods to move so that the distance between the third ends 43 of the connecting rods and the center C1 of the approximately circular structure connected end to end formed by the plurality of clamping block assemblies 50 becomes larger, that is, the diameter of the approximately circular structure C connected end to end formed by the plurality of clamping block assemblies 50 hinged to the third ends 43 of the connecting rods becomes larger; then the belt transfer ring and the belt drum move relative to each other, so that the belt transfer ring passes through the belt drum, and the belt transfer ring and the belt drum are coaxially arranged; then the telescopic driving source 60 drives the mounting plate 30 to rotate, so that the second ends 42 of the connecting rods move synchronously in the direction close to the first ends 41 of the connecting rods, so that the third ends 43 of the connecting rods are hinged to the third ends 43 of the connecting rods. The diameter of the approximately circular structure C formed by the connected clamping block assemblies 50 becomes smaller, so that several clamping blocks 51 contact the belt layer assembly on the belt drum, so that the needles 54 on the clamping blocks 51 penetrate into the belt layer assembly to fix and clamp the belt layer assembly; optionally, the joints of the belt layer assembly are crimped by the joint press 70; then the belt drum contracts and no longer supports and fixes the belt layer assembly; the belt layer transfer ring moves to move the belt layer assembly to the subsequent process; when the forming drum passes through the approximately circular structure C to grab the belt layer assembly, the telescopic drive source 60 drives the mounting plate 30 to rotate, so that several connecting rod second end plates 42 move synchronously in a direction away from the connecting rod first end 41, so that the diameter of the approximately circular structure C formed by several clamping block assemblies 50 hinged to the connecting rod third end 43 becomes larger, so that several clamping blocks 51 no longer contact the belt layer assembly, thereby completing the transfer of the belt layer assembly.

[0036] The present invention mainly uses a newly designed belt layer transfer ring, and a mounting plate 30 rotatably arranged through a moving part 20 drives a plurality of connecting rod assemblies 40 to move synchronously, drives a clamping block assembly 50 connected to the connecting rod assembly 40 to expand and contract synchronously, and forms an approximately circular structure C for clamping the belt layer assembly through a connecting piece 52 and a limiting shaft 53 on the clamping block assembly 50 to clamp and fix the belt layer assembly, thereby ensuring the clamping accuracy of the plurality of clamping block assemblies 50; the connecting piece 52 of the sheet structure passes through the clamping block 51 and the limiting shaft 53 on the clamping block assembly arranged adjacent to it. The limited space setting ensures that the clamping block 51 can ensure clamping accuracy during operation and has a certain amount of movable space so that it will not easily get stuck, which can better transfer the belt layer assembly; by setting the moving part 20 with the arc guide rail 21 and the slider 22 structure, the accuracy of the synchronous movement of several clamping block assemblies 50 is higher, and the joints are crimped by the joint pressing part 70 during the process of clamping the belt layer assembly, without the need for additional joint crimping, which can ensure the crimping quality of the belt layer assembly joints and improve the production efficiency of the belt layer assembly production process.
