[0029] The reinforcing layer 102 described in the present invention is usually a pure rubber strip or a rubber-coated material with steel wires or fibers.

[0030] See attached Figures 3 to 12As shown, the utility model provides a bonding drum 1 (hereinafter referred to as bonding drum) for bonding apex rubber and reinforcing layer, comprising a first rotating shaft 11 and a support plate 12 arranged perpendicular to the first rotating shaft 11, the support plate 12 is provided with a plurality of support seats 13, the support plate 12 is provided with a wire ring support mechanism 20, the wire ring support mechanism 20 comprises a plurality of wire ring support blocks 21, and the wire ring support blocks 21 can move synchronously along the radial direction of the support plate 12, when the wire ring support blocks 21 move radially outward along the support plate 12, the plurality of wire ring support blocks 21 contact with the wire ring 103 for fixing the wire ring 103 03; also includes a capsule assembly 30 arranged on one side of the support seat 13, the capsule assembly 30 has an inflatable and stretchable capsule 31, the capsule 31 is inflated and stretches toward the position of the wire ring support block 21; and a flap mechanism 40 arranged on the other side of the support seat 13, the flap mechanism 40 includes a plurality of flaps 41 that can be flipped synchronously, and the flaps 41 can be in different flipping states with respect to the horizontal direction; the support seat 13 is used to provide support for the flaps 41 and the capsule 31; when the flaps 41 flip upwards and are in an angled state with respect to the horizontal direction, the angle matches the apex 101 and is used to wrap the apex 101 around the flap 41; Figure 4 As shown, when the flap 41 is flipped upward to be approximately vertical to the horizontal direction, it is used to fit the wire ring 103 and the apex 101, or to fit the reinforcing layer 102 to the wire ring 103 and the apex 101 sideways, or to fit the reinforcing layer 102 to the finished tire bead (the finished tire bead refers to the semi-finished product formed after the wire ring 103 and the apex 101 are fitted together) sideways; when the flap 41 and the bladder 31 are at the same height and are approximately horizontal, it is used to receive the reinforcing layer 102 and place the reinforcing layer 102 horizontally on the bladder 31 and the flap 41; Figure 5 As shown, when the capsule 31 is inflated and extends toward the wire ring support mechanism 20 and the flap 41 is extended to be approximately vertical to the horizontal direction, the capsule 31 and the flap 41 are used to perform U-shaped fitting of the reinforcement layer 102 with the wire ring 103 and the apex rubber 101 or to perform U-shaped fitting of the reinforcement layer 102 with the completed tire bead.

[0031] Through the above-mentioned bonding drum 1 capable of bonding the apex rubber 101 and the reinforcing layer 102, the apex rubber 101 and the wire ring 103 can be bonded separately to form a complete tire bead; or the apex rubber 101 and the wire ring 103 are bonded to form a complete tire bead first, and then the reinforcing layer 102 is bonded in a U-shape or sideways to form a composite tire bead; or the apex rubber 101, the wire ring 103 and the reinforcing layer 102 are directly bonded in a U-shape or sideways on the bonding drum to form a composite tire bead. The bonding drum capable of bonding the apex rubber 101 and the reinforcing layer 102 described in the utility model integrates a variety of bonding methods, has the advantages of simple structure, easy use, high flexibility, etc., and can achieve the bonding of the apex rubber and the reinforcing layer by one bonding, has high bonding efficiency, can be applied to different production line layouts, and is conducive to industrial upgrading.

[0032] like Figure 6 As shown, as a first embodiment, the support seat 13 of the utility model is fixedly connected with the wire ring support block 21, and can also be integrally arranged. The support seat 13 is movably arranged on the support disk 12. When the wire ring support block 21 moves radially along the support disk 12, the support seat 13 is driven to move radially along the support disk 12 at the same time. When in use, when the wire ring 103 passes through the capsule 31 and is placed at the position of the wire ring support block 21, the wire ring support block 21 moves radially outward along the support disk 12 to contact the wire ring 103 to fix the wire ring 103. Since the apex 101 and the reinforcement layer 102 both have a certain elasticity, the support seat 13 drives the apex 101 or the reinforcement layer 102 to move synchronously radially toward the position of the wire ring 103. Since the wire ring 103 and the apex 101 or the reinforcement layer 102 move as a whole, it will not affect the fitting of the apex 101 or the reinforcement layer 102.

[0033] like Figure 7 As shown, as a second embodiment, the several support seats 13 described in the utility model are fixedly arranged on the support disk 12, and the wire ring support block 21 is arranged through the support seat 13. When in use, when the wire ring support block 21 moves radially outward along the support disk 12 to contact the wire ring 103 to fix the wire ring 103, the wire ring support block 21 moves through the support seat 13, and the support seat 13 will not move, so there is no need to drive the apex 101 or the reinforcement layer 102 to move. Through this structural setting, the deviation caused by the movement during the bonding process of the apex 101 or the reinforcement layer 102 can be reduced, thereby ensuring the quality of the apex 101 or the reinforcement layer 102 during the bonding process. The following only describes the structure in which the wire ring support block 21 passes through the support seat 13.

[0034] When the apex rubber 101 and the wire ring 103 are bonded to form a complete tire bead, Figure 7As shown, the wire ring 103 is first placed on the wire ring support mechanism 20 manually or automatically by a robot, and a plurality of wire ring support blocks 21 are synchronously moved radially outward along the support plate 12, so that the plurality of wire ring support blocks 21 contact and fix the wire ring 103; the flap 41 is flipped upward to be at an angle to the horizontal direction, and the angle matches the angle of the apex 101 (usually the apex 101 is set at an angle, and the angles of the apex 101 required by different tire models or different manufacturers are also different), and the apex 101 is wound onto the flap 41 by an apex feeding device (not shown), so that the side of the apex 101 away from the flap 41 is parallel to the horizontal direction; as shown Figure 8 As shown, the flap 41 then flips upward to a state that is approximately vertical to the horizontal direction, driving the end of the apex rubber 101 to move toward the wire ring 103, so that the apex rubber 101 and the wire ring 103 are fitted to form a complete tire bead; the flap 41 then flips downward to a state that is approximately vertical to the horizontal direction, driving the end of the apex rubber 101 to move toward the wire ring 103, so that the apex rubber 101 and the wire ring 103 are fitted to form a complete tire bead; Figure 3 The contracted state shown enables the apex rubber 101 to be separated from the flap 41 and complete the unloading of the tire bead.

[0035] When the side of the reinforcing layer 102 is attached to the completed tire bead, the completed tire bead is placed on the wire ring support mechanism 20 manually or automatically by a robot, and a plurality of wire ring support blocks 21 are synchronously moved radially outward along the support plate 12, so that the plurality of wire ring support blocks 21 are in contact with the wire ring 103 of the completed tire bead to fix the completed tire bead; the flap 41 is flipped to an approximately horizontal state to receive the reinforcing layer 102, and the reinforcing layer 102 is wound onto the flap 41 by a reinforcing layer feeding device (not shown); Fig.10 As shown, the flap 41 is then flipped to a state approximately vertical to the horizontal direction, driving the reinforcing layer 102 to move toward the direction of the completed tire bead, so that the completed tire bead and the reinforcing layer 102 are laterally attached to form a composite tire bead; the flap 41 is then flipped downward to Figure 3 The contracted state shown allows the reinforcing layer 102 to be separated from the flap 41 and the composite tire bead to be unloaded.

[0036] When the reinforcing layer 102 is U-shapedly fitted to the completed tire bead, the flap 41 and the capsule 31 are in an approximately horizontal state at the same height to receive the reinforcing layer 102; the reinforcing layer feeding device winds the reinforcing layer 102 onto the capsule 31 and the flap 41; the completed tire bead is placed on the wire ring support mechanism 20 manually or automatically by a robot, and a plurality of wire ring support blocks 21 are synchronously moved radially outward along the support disk 12, so that the plurality of wire ring support blocks 21 pass through the reinforcing layer 102 and contact the wire ring 103 of the completed tire bead to fix the completed tire bead; Fig.12As shown, the capsule 31 is then inflated and stretched toward the wire ring support mechanism 20, and the flap 41 flips upward to be approximately vertical to the horizontal direction, driving the two sides of the reinforcement layer 102 to move toward the direction of completing the tire bead to achieve U-shaped fitting of the reinforcement layer 102 to form a composite tire bead; the capsule 31 is then deflated and reset, and the flap 41 flips downward to a contracted state, so that the reinforcement layer 102 is separated from the capsule 31 and the flap 41 respectively, and the composite tire bead is unloaded.

[0037] When the apex 101, the wire ring 103 and the reinforcing layer 102 are directly laminated on the laminating drum, as shown in FIG. Fig. 9 As shown, the wire ring 103 is placed on the wire ring support mechanism 20 manually or automatically by a robot, and a plurality of wire ring support blocks 21 are synchronously moved radially outward along the support plate 12, so that the plurality of wire ring support blocks 21 are in contact and fixed with the wire ring 103 to complete the tire bead; the flap 41 is turned over to be horizontally arranged, and the reinforcing layer 102 is wound onto the flap 41 by a reinforcing layer feeding device; the flap 41 is turned upward to be at an angle to the horizontal direction, and the apex 101 is wound onto the flap 41 with the reinforcing layer 102 wound thereon by a apex feeding device; as shown in FIG. Fig.10 As shown, when the flap 41 is flipped to a state approximately perpendicular to the horizontal direction, the reinforcing layer 102 and the apex rubber 101 wound on the flap 41 are driven to move toward the wire ring 103 and contact the wire ring 103 to achieve direct side contact between the apex rubber 101, the wire ring 103 and the reinforcing layer 102 to form a composite tire bead; then the flap 41 is flipped to a contracted state, so that the reinforcing layer 102 is separated from the flap 41 and the composite tire bead is unloaded.

[0038] When the apex 101, the wire ring 103 and the reinforcing layer 102 are directly U-bonded on the bonding drum, as shown in FIG. Fig.11 As shown, the flap 41 is flipped to be horizontally arranged at the same height as the capsule 31, and the reinforcing layer 102 is wound onto the horizontally arranged capsule 31 and the flap 41 through the reinforcing layer feeding device; the wire ring 103 is placed on the wire ring support mechanism 20 manually or automatically such as a robot, and a plurality of wire ring support blocks 21 are synchronously moved radially outward along the support disk 12, so that the plurality of wire ring support blocks 21 contact and fix the wire ring 103; the flap 41 is flipped to be at an angle to the horizontal direction, and the angle matches the angle of the apex 101, and the apex 101 is wound onto the flap 41 through the apex feeding device, so that the side of the apex 101 away from the flap 41 is horizontally arranged; as shown Fig.12As shown, the capsule 31 is then inflated and stretched toward the wire ring support mechanism 20, and the flap 41 flips upward to be approximately vertical to the horizontal direction, driving the two sides of the reinforcement layer 102 and the apex rubber 101 to move toward the direction of the wire ring 103 respectively, so as to achieve a U-shaped fit between the reinforcement layer 102, the apex rubber 101 and the wire ring 103 to form a composite tire bead; the capsule 31 is then deflated and reset, and the flap 41 flips downward to a contracted state, so that the reinforcement layer 102 is separated from the capsule 31 and the flap 41 respectively, and the composite tire bead is unloaded.

[0039] like Figures 3 to 7 As shown, the wire ring support mechanism 20 described in the utility model includes a mounting plate 22 fixedly connected to the first rotating shaft 11, and a movable driving source 23 is fixedly arranged on the mounting plate 22, and the other end of the movable driving source 23 is connected to a connecting ring 24, and a plurality of groups of first connecting rod mechanisms 25 are evenly arranged on the circumference of the connecting ring 24, and each group of first connecting rod mechanisms 25 is connected to a wire ring support block 21 at one end away from the connecting ring 24, and the wire ring support block 21 is movably arranged on the support disk 12 through a moving component (not shown, such as a slide rail and a slider combination), and the movable driving source 23 is used to drive the connecting ring 24 to move axially along the first rotating shaft 11, and the wire ring support block 21 is driven to move radially along the support disk 12 through the first connecting rod mechanism 25 connected to the connecting ring 24, and the synchronous movement of several wire ring support blocks 21 is realized through the plurality of first connecting rod mechanisms 25 arranged along the circumference of the connecting ring 24. Through the above-mentioned arrangement, the axial movement of the connecting ring 24 along the first rotating shaft 11 can be converted into the radial movement of the wire ring support block 21 along the support disk 12. The wire ring 103 can be fixed by the radial movement of the wire ring support block 21 along the support disk 12, and can be suitable for wire rings 103 of different specifications.

[0040] like Figures 3 to 7 As shown, the flap mechanism 40 of the utility model also includes a plurality of second link mechanisms 42 connected to the support plate 12, and the plurality of second link mechanisms 42 are evenly distributed along the circumference of the support plate 12. The flap 41 is rotatably arranged on the support seat 13 through the second rotating shaft 43. The flap 41 is provided with a notch 411 at an angle. The first rotating shaft 11 is provided with a moving ring 45 that can move along the axial direction of the first rotating shaft 11. The second link mechanisms 42 are respectively connected to the moving ring 45 and the flap 41. Fig.13 As shown, it is a schematic diagram of a bonding drum connected to a driving mechanism 2. When in use, the movable ring 45 is connected to and used in conjunction with the driving mechanism 2. The driving mechanism 2 drives the movable ring 45 to move axially along the first rotating shaft 11, and then drives the flap 41 to rotate through the second connecting rod mechanism 42 hinged to the movable ring 45.

[0041] Specifically, the second link mechanism 42 is a first link 421 and a second link 422 hinged to each other, and the first link 421 is arranged near the middle position of the second link 422, so that the second link mechanism 42 has a first link end 423, a second link end 424 and a third link end 425. The first link end 423 is hinged to an end of the support plate 12 away from the wire ring support mechanism 20, the second link end 424 is hinged on the circumference of the movable ring 45, and the third link end 425 is movably arranged in the slot 411 of the flap 41 through the fixed shaft 44. When the driving mechanism 2 drives the moving ring 45 to move along the axial direction of the first rotating shaft 11, the second ends 424 of the connecting rods hingedly arranged on the circumference of the moving ring 45 are close to or away from the first ends 423 of the connecting rods, thereby driving the first ends 423 of the connecting rods to rotate around the support plate 12, driving the third ends 425 of the connecting rods to move in the notches 411 of the flap 41, and then driving the flap 41 to rotate around the support seat 13, so as to realize that the flap 41 is in a different flipping state from the horizontal direction. Preferably, the number of the second connecting rod mechanisms 42 is the same as the number of the flaps 41.

[0042] like Figure 7 , 8 As shown in Figure 13, the working principle of the driving mechanism 2 driving the flap 41 to flip is as follows: when the driving mechanism 2 drives the movable ring 45 to move along the axis D to C of the first rotation axis, it drives the second ends 424 of the plurality of connecting rods hinged along the circumference of the movable ring 45 to move toward the direction close to the first end 423 of the connecting rod, and drives the first end 423 of the connecting rod to rotate counterclockwise around the support plate 12, so that the third end 425 of the connecting rod moves in the groove 411 of the flap 41 toward the direction close to the second rotation axis 43, thereby driving the flap 41 to move counterclockwise around the second rotation axis 43, so that the flap 41 rotates upward. When the driving mechanism 2 drives the moving ring 45 to move in the direction of the axis C to D of the first rotating shaft, it drives the second ends 424 of the connecting rods hinged along the circumference of the moving ring 45 to move in the direction away from the first ends 423 of the connecting rods, and drives the first ends 423 of the connecting rods to rotate clockwise around the support plate 12, so that the third ends 425 of the connecting rods move in the groove 411 of the flap 41 in the direction away from the second rotating shaft 43, thereby driving the flap 41 to move clockwise around the second rotating shaft 43, causing the flap 41 to move downward.

[0043] like Fig.12As shown, the support seat 13 of the utility model has a capsule support end 131 arranged horizontally, and the capsule has a capsule end 311, and the capsule end 311 is arranged on the side of the capsule support end 131 close to the wire ring support block 21, and the capsule support end 131 is arranged horizontally, so that the capsule 31 is arranged horizontally on the capsule support end 131 to receive the reinforcement layer. The capsule support end 131 is also provided with a capsule vent 132, and the capsule vent 132 is connected to the gas source (not shown) through a ventilation pipeline (not shown), and is used to pass gas into the capsule 31. When gas is introduced into the capsule 31 through the capsule vent 132, the capsule 31 is inflated and moves toward the side of the wire ring support block 21, thereby driving the reinforcement layer arranged on the capsule 31 to move toward the side of the wire ring support block 21, thereby cooperating with the flap 41 to flip upward to a state that is approximately vertical to the horizontal direction, driving the reinforcement layer arranged on one side of the flap 41 to move toward the side of the wire ring support block 21, thereby realizing U-shaped fitting of the reinforcement layer.

[0044] like Fig.12 As shown, since the reinforcing layer 102 and the apex 101 are both wound onto the bonding drum 1 by winding, the bonding drum 1 needs to rotate during the bonding process of the apex 101 or the reinforcing layer 102, and the rotation is also achieved by driving the first rotating shaft 11 to rotate by the driving mechanism 2, thereby driving the rotation of the entire bonding drum. Furthermore, in order to avoid the ventilation pipeline for ventilating the capsule 31 from being entangled in a disorderly manner and thus affecting the rotation of the bonding drum 1, a central vent hole 111 is provided on the first rotating shaft 11 of the utility model along the central direction of rotation, that is, the setting direction of the central vent hole 111 is parallel to the axial direction of the first rotating shaft 11, and the central vent hole 111 is set through the first rotating shaft 11. When in use, the air source is connected to one end of the central vent hole 111, and the other end of the central vent hole 111 is connected to the capsule vent hole 132 through the ventilation pipeline to ventilate the capsule. Through the above arrangement, the rotation of the entire bonding drum is smoother.

[0045] like Fig.12 As shown, in order to better limit the position of the wire ring 103, the wire ring support block 21 of the utility model has a support portion 211 and at least one limiting portion 212, so as to better limit the position of the wire ring 103. When the wire ring 103 is fixed, the support portion 211 of the wire ring support block 21 contacts the wire ring 103 for fixing, and the shape of the limiting portion 212 matches the shape of the cross section of the wire ring 103, so as to cooperate with the support portion 211 to better limit the wire ring 103 from at least two directions of the wire ring 103.

[0046] The utility model mainly designs a new bonding drum 1 that can bond apex rubber and reinforcement layer, and realizes multiple bonding modes of wire ring and apex rubber or wire ring, apex rubber and reinforcement layer side bonding or U-shaped bonding through a wire ring support mechanism 20, a capsule assembly 30 and a flap mechanism 40 that can move independently from each other. It has the advantages of simple structure and easy use, and can be optimized and suitable for different production line layouts.
