Description

[0002] At present, the process of laminating the reinforcing layer in tire production is usually to first laminate the wire ring and the apex rubber on the laminating drum to form a completed tire bead, and then laminate the reinforcing layer on the laminating drum and place the completed tire bead on the reinforcing layer to form a composite tire bead through U-shaped lamination or side lamination. However, the above production method requires a separate production device to first produce semi-finished products such as the tire bead or the reinforcing layer (the reinforcing layer includes the cord or the cord and the rubber strip), and then laminate the semi-finished products. This production method requires multiple production equipment, and the materials need to be repeatedly circulated and stored, resulting in a large amount of waste and a long production cycle.

[0003] In addition, the current production equipment usually places the apex on the bead ring in parallel with the edge of the bead ring, and then drives the apex to flip around the bead ring at a certain angle through the expansion of the capsule to achieve the apex being attached to the bead ring, i.e., the apex is flatly attached.

When replacing bonding drums of different diameters, the clamping jaw assembly always maintains the same second pasting angle in the circumferential section of the bonding drum or keeps the clamping jaw assembly always facing the center of the bonding drum in the circumferential section of the bonding drum, thereby adjusting the second pasting angle of the clamping jaw assembly to better bond the apex glue. The above-mentioned settings can better meet the production of apex glues or wire rings of different specifications, and have stronger versatility. The present invention also provides a production method for forming a composite tire bead, which can directly form a composite tire bead by bonding a bare steel wire ring, a rubber-covered steel wire ring or a cloth-covered steel wire ring with a apex rubber, a cord layer and a film layer, and has the advantage of high production efficiency.

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0034] like Figures 1 to 16As shown, the present invention discloses a production unit 1 (hereinafter referred to as the production unit) for directly producing a composite tire bead by combining a wire ring and each film layer on a set of equipment, comprising a wire ring presetting device 10, wherein the wire ring presetting device 10 is used to receive the wire ring, and the wire ring can be transferred to the wire ring presetting device 10 by manual or mechanical structure; a bonding drum device 20, wherein the bonding drum device has a rotatable bonding drum 21, and the bonding drum 21 has an inflatable reverse-wrapped capsule (not shown), and the bonding drum 21 is used to receive a rubber layer (the rubber layer includes a cord, a first film and a second film) and a wire ring, so as to produce a composite tire bead; a ring holding transfer device movable between the wire ring presetting device 10 and the bonding drum device 20 40, the ring holding transfer device 40 is used to grab the wire ring from the wire ring pre-setting device 10 and place the wire ring on the bonding drum 21; it also includes a rubber layer feeding rack 30 arranged vertically with the bonding drum 21, for providing various rubber layers required for producing the composite tire ring, and bonding the rubber layers to the bonding drum 21; and a apex rubber standing feeding device 50 arranged opposite to the bonding drum 21, the apex rubber standing feeding device 50 is used to provide the apex rubber 100 and stick the apex rubber 100 upright on the wire ring (the standing sticking described in the present invention is a different sticking method relative to the aforementioned flat sticking, specifically refers to a sticking method in which the apex rubber 100 is directly stuck to the wire ring at a forming angle with the wire ring, without the need to flip or move relative to the wire ring).

[0035] Through the above arrangement, the reinforcing layer (the reinforcing layer refers to the cord or the cord and the second film) is firstly bonded to the bonding drum 21 through the rubber layer feeding rack 30, and the wire ring is placed on the wire ring pre-setting device 10 for centering manually or automatically by a robot, and then the wire ring is removed from the wire ring pre-setting device 10 by the ring holding transfer device 40 and transferred to the corresponding position of the reinforcing layer on the bonding drum 21; the apex rubber of fixed length is vertically bonded to the wire ring through the apex rubber vertical bonding feeding device 50, and then the capsule on the bonding drum 21 is inflated, so that the capsule expands to bond the side of the reinforcing layer to the wire ring and the apex rubber 100 or U-shape bond to the wire ring and the apex rubber 100, thereby completing the direct production of the composite tire ring.

[0036] like Figure 3As shown, the apex glue standing feeding device 50 described in the present invention includes a support seat 51, a limit support mechanism 52 rotatably arranged on the support seat 51, the limit support mechanism 52 is used to provide support and limit for the apex glue 100 when the apex glue 100 is bonded to the wire ring on the bonding drum 21; a clamping mechanism 53 is arranged on the limit support mechanism 52 at one end away from the support seat 51, the clamping mechanism 53 has a clamping jaw assembly 531 with adjustable spacing, and the clamping jaw assembly 531 is used to clamp the apex glue 100; it also includes a swing driving source 54 arranged on the support seat 51, the driving end of the swing driving source 54 is connected to the end of the limit support mechanism 52 close to the support seat 51, and the swing driving source 54 is used to drive the limit support mechanism 52 to rotate around the support seat 51, thereby driving the clamping jaw assembly 531 connected to the limit support mechanism 52 to avoid the bonding drum 21 or to bond the apex glue close to the bonding drum 21.

[0037] Through the above structure, when the apex 100 is bonded, the apex 100 is clamped by the distance-adjustable clamping jaw assembly 531, and the swing driving source 54 drives the limit support mechanism 52 to rotate in the counterclockwise direction, thereby driving the clamping jaw assembly 531 to move the apex 100 to the bonding drum 21 to lightly press the apex 100 onto the wire ring. As the bonding drum 21 rotates, the apex 100 is bonded to the circumference of the wire ring. The apex vertical bonding feeding device 50 described in the present invention is mainly used for feeding and bonding the apex 100 that has been cut to a fixed length. Of course, the rolled apex 100 can also be bonded to the wire ring and then cut to a fixed length.

[0038] The support seat 51 of the present invention is connected to the position-limiting support mechanism 52 through a support shaft 511, and the support shaft 511 is arranged on the support seat 51. The position-limiting support mechanism 52 is rotatably arranged on the support shaft 511 through a first bearing member (not shown). The position-limiting support mechanism 52 has a first support end 521, a second support end 522 and a fulcrum 502, the support seat 51 is connected to the fulcrum 502 of the position-limiting support mechanism, the swing drive source 54 is connected to the first support end 521 of the position-limiting support mechanism, the clamping mechanism 53 is connected to the second support end 522 of the position-limiting support mechanism, and the position-limiting support mechanism 52 is tilted on the support seat 51, and the distance between the first support end 521 of the position-limiting support mechanism and the fulcrum 502 is smaller than the distance between the second support end 522 of the position-limiting support mechanism and the fulcrum 502, so that the position-limiting support mechanism 52 and the support seat 51 form a lever connection. Through the above arrangement, the swing driving source 54 only needs to drive the supporting first end 521 of the limiting support mechanism to move a very small distance in the vertical direction, and the moving distance of the supporting second end 522 of the limiting support mechanism in the vertical direction will be proportionally enlarged, which can effectively save space.

[0039] The limiting support mechanism 52 described in the present invention includes a first side plate 523 and a second side plate 524 arranged in parallel, and a bottom plate (not shown) arranged perpendicular to the first side plate 523 and the second side plate 524, respectively. A plurality of feed rollers 526 are arranged in parallel between the first side plate 523 and the second side plate 524. The feed rollers 526 are used to support the apex. The mechanism also includes a plurality of guide roller groups arranged on the bottom plate. The guide roller groups have guide rollers 527 arranged in pairs. When the bonding drum 21 rotates to drive the apex to move, the guide rollers 527 are used to guide and limit the apex.

[0040] like Figure 4 As shown, the clamping mechanism 53 described in the present invention includes a mounting plate 532, a mobile driving source 533 arranged on the mounting plate 532, and a first synchronous transmission mechanism 534, the other end of the first synchronous transmission mechanism 534 is connected to the clamping jaw assembly 531, and the mobile driving source 533 adjusts the distance between the clamping jaw assemblies 531 through the first synchronous transmission mechanism 534.

[0041] Preferably, the clamping jaw assembly 531 described in the present invention is two rotatable rotating rollers 311. When the two rotating rollers 311 clamp the apex and drive the apex to be conveyed forward through the bonding drum 21, there is rolling friction between the rotating rollers 311 and the apex, so that the movement of the apex is not affected while ensuring that the apex is clamped and fixed by the rotating rollers, and the apex is not easily damaged.

[0042] like Figures 4 to 6As shown, the first synchronous transmission mechanism 534 of the present invention includes a cam matching element 341 arranged at the driving end of the mobile driving source 533, the cam matching element 341 has a cam groove first end 3411 and a cam groove second end 3412, the cam groove first end 3411 and the cam groove second end 3412 form a V-shaped structure, and also includes two cam mounting members 343 movably arranged on the mounting plate 532 through a first moving component (such as a slide rail and a slider combination, not shown), the cam mounting member 343 has a first mounting end 3431 and a second mounting end 3432, A rotating shaft 344 is arranged on the first mounting end 3431, and a rotating element 345 is rotatably arranged on the rotating shaft 344. The two rotating elements 345 are respectively arranged in contact with the first end 3411 of the cam groove and the second end 3412 of the cam groove, and the two rotating elements 345 are arranged in a V-shaped structure formed by the first end 3411 of the cam groove and the second end 3412 of the cam groove. The two rotating rollers 311 are respectively arranged on the second mounting ends 3432 of the two cam mounting members 343, and also include an elastic element 346 arranged between the cam mounting member 343 and the mounting plate 532. The cam mating element 341 is driven to move by the mobile driving source 533, so that the two rotating elements 345 are contacted and arranged at different positions of the V-shaped structure on the cam mating element 341. Since the spacing between the two sides at different positions on the V-shaped structure is different, when the two rotating elements 345 drive the two cam mounting parts 343 to move closer or farther from each other, the two rotating rollers 311 are driven to move closer or farther from each other to clamp the apex 100. By setting the elastic element 346, when the two groups of rotating elements 345 are acted on by the force of the V-shaped structure on the cam mating element 341 and move closer to each other, they will not collide with each other due to the reverse rebound force of the elastic element 346. And through the above-mentioned setting, the spacing between the two rotating rollers 311 can be set as needed, which can be suitable for clamping apex 100 with different widths.

[0043] like Figure 6 As shown, preferably, the angle a1 formed by the first end 3411 of the cam groove and the center line a0 of the cam matching element 341 and the angle a2 formed by the second end 3412 of the cam groove and the center line a0 of the cam matching element 341 are equal, thereby achieving simultaneous and equal movement of the two rotating rollers 311, approaching or moving away from each other.

[0044] like Figure 8 and 9As shown, since the shape of the apex 100 is similar to a triangle, it has a first end face 101, a second end face 102 and a third end face 103. The first end face 101 of the apex is an arc surface that matches the wire ring, and the second end face 102 and the third end face 103 of the apex are inclined surfaces. The apex 100 of different specifications has different angles formed by the second end face 102 and the third end face 103 of the apex, including an isosceles triangle formed by the second end face 102 and the third end face 103 of the apex, and a non-isosceles triangle formed by the second end face 102 and the third end face 103 of the apex. The clamping mechanism 53 clamps and fixes the apex by clamping the second end face 102 and the third end face 103 of the apex. When the second end face 102 and the third end face 103 of the apex form a non-isosceles triangle, if the clamping jaw assembly 531 still vertically clamps the apex 100, when the apex 100 is attached to the surface of the wire ring, due to uneven force, the apex 100 may be displaced or the apex 100 may be loose on one side and tight on the other side when attached to the wire ring.

[0045] Therefore, in order to better meet the requirements of attaching the apex 100 of different angles to the wire ring, such as Figure 7 and 8 As shown, the apex adhesive vertical pasting feeding device 50 of the present invention further includes an angle adjustment mechanism 56, so as to set the first pasting angle of the clamping jaw assembly 531. The first pasting angle is the angle of the clamping jaw assembly 531 in a plane coplanar with the axial cross section Q of the pasting drum 21. Through the first pasting angle setting, the clamping jaw assembly 531 is set parallel to the angle bisector a3 of the angle formed by the second end face 102 and the third end face 103 of the apex adhesive. Figure 8 As shown, b1 is when the second end face 102 and the third end face 103 of the apex are isosceles triangles, the clamping jaw assembly 531 clamps the apex 100 to fit vertically to the wire ring on the fitting drum 21. b2 is when the second end face 102 and the third end face 103 of the apex are non-isosceles triangles, the clamping jaw assembly 531 adjusts the first fitting angle through the angle adjustment mechanism 56, so that the clamping jaw assembly 531 clamps the apex 100 to fit the wire ring on the fitting drum 21 in a direction parallel to the angle bisector a3 of the angle formed by the second end face 102 and the third end face 103 of the apex.

[0046] like Figure 7As shown, the clamping mechanism 53 of the present invention is arranged on the limiting support mechanism 52 through a connecting bracket 57. Specifically, the angle adjustment mechanism 56 described in the present invention includes two groups of hinge mechanisms 561, and the two groups of hinge mechanisms 561 are respectively connected to the clamping mechanism 53 and the connecting bracket 57, specifically connected to the mounting plate 532 on the clamping mechanism 53, the hinge mechanism 561 includes a first hinge 611 and a second hinge 612 that are hingedly arranged, the first hinge 611 is fixedly provided with a hinge shaft 613, and the second hinge 612 is rotatably arranged on the hinge shaft 613 through a second bearing member (not shown); the angle adjustment mechanism 56 also includes an adjustment component 615, and the adjustment component 615 includes a length adjustment member 6151 and a fastener 6152, and the length adjustment member 6151 and the fastener 6152 pass through the connecting bracket 57 and are connected to one group of hinge mechanisms 561, the length adjustment member 6151 is used to adjust the height of the first hinge 611 and the connecting bracket 57, and the fastener 6152 is used to fix the connecting bracket 57 and the first hinge 611. When the height of one set of hinge mechanisms 561 is adjusted by the length adjusting member 6151 and the fastener 6152, the height of the other set of hinge mechanisms 561 remains unchanged, and the height difference formed by the two sets of hinge mechanisms 561 causes the material clamping mechanism 53 to be tilted, thereby driving the clamping claw assembly 531 on the material clamping mechanism 53 to tilt. And because the first hinge 611 and the second hinge 612 are hingedly arranged, when the material clamping mechanism 53 tilts, although the position of one set of hinge mechanisms 561 is raised, the first hinge 611 will not be tilted and connected to the connecting bracket 57, and the first hinge 611 will still be stably connected to the connecting bracket 57, ensuring the stability of the connection setting.

[0047] The height adjustment of the hinge mechanism 561 is achieved by manually adjusting the length adjustment member 6151 and the fastener 6152. As an automatic adjustment method, the other parts of the angle adjustment mechanism 56 are the same as those in the above embodiment, and only the adjustment component is different. In this embodiment, the adjustment component 615 includes a linear bearing mechanism (not shown) arranged between the connecting bracket 57 and the first hinge 611, and a lifting drive source (not shown). The lifting drive source is arranged on the connecting bracket 57, and the driving end of the lifting drive source is connected to the first hinge 611 of one group of hinge mechanisms. The first hinge 611 is driven to move upward relative to the connecting bracket 57 by the lifting drive source, and is guided by the linear bearing mechanism for linear movement, so that one group of first hinges 611 is lifted relative to the connecting bracket 57.

[0048] When producing wire rings of different diameters, the diameter of the bonding drum 21 used is also different, that is, the height position of the clamping jaw assembly 531 to place the apex 100 on the wire ring is also different. Therefore, when the swing drive source 54 of the present invention drives the limit support mechanism 52 to rotate around the support shaft 511, in addition to driving the clamping jaw assembly 531 away from the bonding drum 21 or close to the bonding drum 21, it is also used to adjust the height of the clamping jaw assembly 531 to be suitable for bonding drums 21 of different diameters to produce wire rings of different specifications. It should be noted that when the clamping jaw assembly 531 clamps the apex 100 to be bonded to the bonding drum 21, the angle of the clamping jaw assembly 531 in the plane coplanar with the circumferential radial section P of the bonding drum 21 is the second bonding angle. The first bonding angle and the second bonding angle of the clamping jaw assembly 531 form the bonding angle of the apex 100 bonded to the bonding drum 21. Usually, the size of the second bonding angle also needs to be adjusted corresponding to tires of different outer diameters. In order to simplify the debugging and production of bonding drums 21 of different diameters, after the debugging of the second bonding angle when the clamping jaw assembly 531 clamps the apex 100 and bonds with the bonding drum 21 is completed, when the bonding drum 21 of different diameters is replaced, the clamping jaw assembly 531 can be kept to bond at the same second bonding angle. After replacing a different bonding drum 21, during the process of the swing drive source 54 driving the limit support mechanism 52 to rotate around the support shaft 511, the clamping mechanism 53 can maintain the original second bonding angle unchanged by setting a movement compensation mechanism. Fig.10 As shown, when the bonding drum 21A is replaced by 21B, the swing drive source 54 drives the limit support mechanism 52 to rotate clockwise around the support shaft 511, and the clamping jaw assembly 531 always remains vertically downward within the circular cross-section of the bonding drum 21, that is, the second bonding angle of the clamping jaw assembly 531 remains unchanged.

[0049] like Fig.10As shown, therefore, as a first implementation method for realizing the above-mentioned technical effects, the support shaft 511 is fixedly arranged on the support seat 51, and the support shaft 511 and the support seat 51 can be arranged integrally or separately, and a first fixed shaft 571 is rotatably arranged on one end of the limiting support mechanism 52 close to the connecting bracket 57, and the connecting bracket 57 is fixedly arranged on the first fixed shaft 571, and the movement compensation mechanism is a sprocket and chain structure, specifically including a first sprocket 582 and a second sprocket 583 connected by a first chain 581, and the first sprocket 582 is fixedly arranged on the support shaft 511, and the second sprocket 583 is fixedly arranged on the first fixed shaft 571. When the swing drive source 54 drives the limit support mechanism 52 to rotate around the support shaft 511, the limit support mechanism 52 as a whole rotates with the support shaft 511 as the rotation center. Since the support shaft 511 is fixedly set on the support seat 51 and does not rotate, the first sprocket 582 fixedly set with the support shaft 511 does not rotate, and the second sprocket 583 connected to the first sprocket 582 through the first chain 581 does not rotate. Therefore, the connecting bracket 57 fixedly set with the second sprocket 583 through the first fixed shaft 571 does not rotate either. That is, although the clamping jaw assembly 531 follows the limit support mechanism 52 to translate around the support shaft 511 in a plane (the plane is set in the same plane as the circumferential radial section of the bonding drum P), the angle of the clamping jaw assembly 531 in the plane always remains unchanged, so that when using bonding drums 21 with different diameters to produce tires of different specifications, debugging can be reduced as much as possible to adapt to production within the maximum specification range. It should be noted that the sprocket and chain structure in the above embodiment can also be replaced by a synchronous belt and synchronous pulley structure without considering the load-bearing capacity. Other structures are the same as the sprocket and chain structure and will not be described in detail here.

[0050] Of course, in order to achieve the best fitting quality between the apex 100 and the wire ring, the clamping jaw assembly 531 should be arranged toward the center of the bonding drum 21 in the circumferential radial section P of the bonding drum 21, so that the fitting quality between the apex 100 and the wire ring is the best. Fig.11As shown, as the second embodiment, other structures are the same as the first embodiment, except that the moving compensation mechanism is a compensation drive source 584, and the compensation drive source 584 is independently arranged or arranged on the limiting support mechanism 52, and the driving end of the compensation drive source 584 is connected to the first fixed shaft 571. When the bonding drum is replaced from 21A to 21B, the swing drive source 54 drives the limit support mechanism 52 to rotate around the support shaft 511 in the clockwise direction at a first angle, and drives the clamping mechanism 53 to rotate at the same angle. Then, the compensation drive source 584 drives the connecting bracket 57 to rotate in the counterclockwise direction (i.e., in the opposite direction of the rotation direction of the limit support mechanism 52) at a second angle. The second angle can be the same as the first angle to offset the angle change that occurs when the clamping mechanism 53 rotates following the limit support mechanism 52, thereby ensuring that the clamping mechanism 53 maintains the original angle unchanged within the circular cross-section of the bonding drum 21; of course, the second angle can also be directly set so that the clamping claw assembly 531 in the clamping mechanism 53 still remains set toward the center direction of the bonding drum 21 within the circular cross-section of the bonding drum 21.

[0051] like Fig.12The third embodiment of the present invention is shown. Compared with the second embodiment, this embodiment has lower cost. The difference between it and the first embodiment is that the support shaft 511 is rotatably arranged on the support seat 51. In addition to the sprocket and chain structure, the mobile compensation mechanism specifically includes a first sprocket 582 and a second sprocket 583 connected via a first chain 581. The first sprocket 582 is fixedly arranged on the support shaft 511, and the second sprocket 583 is fixedly arranged on the first fixed shaft 571. The mobile compensation mechanism also includes a handle and a brake (not shown) arranged on the support shaft 511. The handle is used to drive the support shaft 511 to rotate, and the brake is used to fix the rotation position of the support shaft 511 to prevent the support shaft 511 from rotating at will. When the bonding drum 21A is replaced by 21B, the swing drive source 54 drives the limit support mechanism 52 to rotate around the support shaft 511 in the clockwise direction by a first angle, and the support shaft 511 is braked and does not rotate, so the first sprocket 582 fixedly arranged with the support shaft 511 does not rotate, and the second sprocket 583 connected with the first sprocket 582 through the first chain 581 does not rotate, so the connecting bracket 57 fixedly arranged with the second sprocket 583 through the first fixed shaft 571 does not rotate, that is, the clamping jaw assembly 531 follows the limit support mechanism 52 to rotate in the plane around the support shaft 511. The jaw assembly 531 rotates, but the angle formed by the jaw assembly 531 in the circumferential cross-section of the bonding drum 21 remains unchanged. The brake is then released, and the support shaft 511 is driven to rotate through the handle, thereby driving the first sprocket 582 fixed to the support shaft 511 to rotate, and the second sprocket 583 is driven to rotate through the first chain 581, thereby driving the first fixed shaft 571 fixed to the second sprocket 583 to rotate, thereby driving the connecting bracket 57 fixed on the first fixed shaft 571 to rotate, and driving the jaw assembly 531 to rotate in the circumferential radial cross-section P of the bonding drum 21 toward the center 21C of the bonding drum.

[0052] That is to say, when replacing the bonding drum 21 of different sizes, the clamping mechanism 53 can maintain the second bonding angle of the clamping mechanism 53 unchanged within the circumferential radial section P of the bonding drum 21 by setting a moving compensation mechanism to facilitate the change of model and debugging, or the second bonding angle of the clamping mechanism 53 can be changed by the moving compensation mechanism, but the clamping mechanism 53 is always facing the center of the bonding drum, so that the apex rubber can be better bonded with the wire ring on the bonding drum 21.

[0053] like Figure 3The apex adhesive standing feeding device 50 of the present invention further comprises a mounting seat 59, and the support seat 51 is movably arranged on the mounting seat 59, so that the support seat 51 can move along the axial direction of the bonding drum 21, thereby being able to move along the axial direction of the bonding drum 21 with the clamping jaw assembly 531 holding the apex adhesive 100, so as to bond the apex adhesive 100 to the wire rings at different positions of the bonding drum 21. The apex adhesive standing feeding device 50 of the present invention can be provided separately, or movably arranged on the ring holding booster device, so as to save space.

[0054] It should be noted that when the apex adhesive standing feeding device 50 described in the present invention is in use, the material head of the apex adhesive 100 cut to a fixed length is first pressed lightly on the wire ring manually or automatically by other mechanical structures, and the apex adhesive 100 is clamped by the clamping jaw assembly 531, and then the swing driving source 54 drives the limiting support mechanism 52 to rotate in the direction close to the bonding drum 21, so that the clamping jaw assembly 531 clamps the apex adhesive 100 and makes it contact with the wire ring (the contact described in the present invention refers to the apex adhesive 100 lightly pressing on the wire ring, but does not affect the rotation of the bonding drum 21), and then the bonding drum 21 rotates, driving the apex adhesive 100 to fit on the wire ring to complete the bonding of the apex adhesive.

[0055] The wire ring presetting device 10 of the present invention comprises a plurality of positioning rollers (not shown) which can move synchronously in the radial direction, and is used to fix the wire ring from within the circumference of the wire ring so as to grasp the wire ring.

[0056] The ring holding transfer device 40 of the present invention is used to grab the wire ring from the outside of the circumference of the wire ring, so as to place the wire ring on the bonding drum 21. Fig.13 As shown, the ring-holding transmission device 40 includes a transmission ring body 41, on which there is a hollow approximately circular structure 411, the approximately circular structure is used for the laminating drum 21 to pass through, and the transmission ring body 41 is provided with a telescopic driving source 42 and a second synchronous transmission mechanism 43, the driving end of the telescopic driving source 42 is connected to one end of the second synchronous transmission mechanism 43, and the other end of the second synchronous transmission mechanism 43 is rotatably provided with a ring-holding roller 44. When the telescopic driving source 42 drives the second synchronous transmission mechanism 43 to rotate, it drives a plurality of ring-holding rollers 44 to approach the center of the approximately circular structure 411 on the transmission ring body or to move away from the center of the approximately circular structure 411, and when the ring-holding rollers 44 are mutually close to the center of the approximately circular structure 411, the wire ring is fixedly grasped, and when the ring-holding rollers 44 are mutually away from the center of the approximately circular structure 411, the wire ring is released.

[0057] Specifically, the second synchronous transmission mechanism 43 includes a plurality of third sprockets 431 and a plurality of fourth sprockets 432 rotatably arranged on the transfer ring body 41, and a second chain 433 connecting the plurality of third sprockets 431 and the fourth sprocket 432, and also includes a connecting rod 434 coaxially arranged with the fourth sprocket 432, the connecting rod 434 and the fourth sprocket 432 are respectively arranged on both sides of the transfer ring body 41, the ring holding roller 44 is rotatably arranged on the end of the connecting rod 434 away from the fourth sprocket 432, and the driving end of the telescopic driving source 42 is fixed to the second chain 433 through the first connecting block 435. When the telescopic driving source 42 drives the second chain 433 to move, the transmission of the third sprocket 431 drives the fourth sprockets 432 to rotate synchronously. When the fourth sprocket 432 rotates, it drives the connecting rods 434 coaxially arranged therewith to rotate at the same angle, thereby driving the ring-holding rollers 44 fixedly arranged with the connecting rods 434 to approach the center of the approximately circular structure 411 on the transfer ring body or to move away from the center of the approximately circular structure 411. And the above structure can be used to fix and grab wire rings of different outer diameters, and has a wide range of applications. Of course, the telescopic driving source 42 described in the present invention can also be fixedly arranged with any of the third sprockets 431 or the fourth sprocket 432, and by driving the third sprocket 431 or the fourth sprocket 432 to rotate, it drives the fourth sprockets 432 to rotate synchronously.

[0058] Through the above-mentioned equipment, during production, the cord 401 can be first provided through the rubber layer feeding rack 30, the cord 401 can be cut to a fixed length, and the cord 401 cut to a fixed length can be bonded to the bonding drum 21; the wire ring is transferred to the wire ring pre-setting device 10 by manual or mechanical means, and the wire ring pre-setting device 10 fixes and grabs the wire ring from the circumference of the wire ring; the wire ring is fixedly grabbed from the outside of the circumference of the wire ring by the ring holding transfer device 40, and the wire ring is moved to the bonding drum 21, and the wire ring is placed at a designated position on the bonding drum 21 bonded with the cord 401; the apex rubber 100 is vertically bonded to the circumference of the wire ring by the apex rubber vertical bonding feeding device 50; and the capsule on the bonding drum 21 is inflated so that the cord 401U is wrapped or laterally bonded to the apex rubber and the wire ring to form a composite tire bead.

[0059] It should be noted that the wire ring mentioned above is a cloth-wrapped wire ring formed by wrapping a bare wire ring with a cloth wrapping machine, and the production unit may further include a cloth wrapping machine (not shown), which is used to provide a cloth-wrapped wire ring for the wire ring pre-setting device 10. Forming a cloth-wrapped wire ring by winding with a cloth wrapping machine is a prior art and will not be described in detail here.

[0060] In actual production, there is another type of steel bead that is a rubber-coated steel bead, that is, a layer of film is attached to the outside of the bare steel bead. In the prior art, for the production of composite tires with such rubber-coated steel bead, independent production equipment is used to first attach film to the bare steel bead to form a rubber-coated steel bead, and then the subsequent reinforcement layer and apex adhesive are attached. When producing such composite tires with rubber-coated steel bead, more production equipment is required and repeated turnover and storage are required. However, the above-mentioned production unit with apex adhesive vertical attachment feeding device can realize direct online production of composite tires with rubber-coated steel bead.

[0061] The specific production method is as follows: first, a first film 402 is provided through the rubber layer feeding rack 30 (the first film 402 is a film that wraps the bare steel wire ring to form a rubber-coated steel wire ring), the first film 402 is cut to a fixed length, and the first film 402 cut to a fixed length is bonded to the bonding drum 21; the bare steel wire ring 200 is transferred to the steel ring pre-setting device 10 by means of a manual or mechanical structure, and the steel ring pre-setting device 10 fixes and grabs the steel wire ring from the circumference of the bare steel wire ring 200; the steel wire ring is fixedly grabbed from the outside of the circumference of the bare steel wire ring 200 by the ring holding transfer device 40, and the bare steel wire ring 200 is moved to the bonding drum 21, and the bare steel wire ring 200 is placed at a designated position on the bonding drum 21 bonded with the first film 402, and the capsule on the bonding drum 21 is inflated so that the two ends of the first film 402 are respectively The rubber-coated steel wire ring is bonded to the circumference of the bare steel wire ring 200 to form a rubber-coated steel wire ring; the ring holding transfer device 40 moves to the bonding drum 21 to fix and grab the rubber-coated steel wire ring from the outside of the circumference of the rubber-coated steel wire ring, unloads the rubber-coated steel wire ring from the bonding drum 21 and temporarily stores the rubber-coated steel wire ring; the rubber layer feeding rack 30 provides the curtain fabric 401, cuts the curtain fabric 401 to a fixed length, and bonds the curtain fabric 401 cut to a fixed length to the bonding drum 21. The bonding drum 21 is placed on the bonding drum 21; the ring holding transfer device 40 moves the rubber-coated steel wire ring temporarily stored there to the bonding drum 21, and places the rubber-coated steel wire ring at a designated position on the bonding drum 21 bonded with the cord fabric; the apex rubber 100 is vertically bonded to the circumference of the steel wire ring through the apex rubber vertical bonding feeding device 50; the capsule on the bonding drum 21 is inflated so that the cord fabric is U-wrapped or side-bonded to the apex rubber 100 and the steel wire ring to form a composite tire bead.

[0062] Of course, as another production method, after the rubber-coated steel wire ring is formed on the bonding drum 21, the apex 100 is vertically attached to the rubber-coated steel wire ring through the apex adhesive vertical attachment feeding device 50, and then the rubber-coated steel wire ring with the apex adhesive 100 is fixed and grasped by the ring holding transfer device 40, and the rubber-coated steel wire ring with the apex adhesive 100 is unloaded from the bonding drum 21 and temporarily stored; then the cord fabric 401 is provided by the rubber layer feeding rack 30, and the cord fabric 401 is Cut to a fixed length, and bond the cut-to-length cord 401 to the bonding drum 21; the ring-holding transfer device 40 then moves the rubber-coated steel wire ring bonded with the apex rubber 100 temporarily stored thereto to the bonding drum 21, and places the rubber-coated steel wire ring bonded with the apex rubber 100 at a designated position on the bonding drum 21 bonded with the cord 401; and the capsule on the bonding drum 21 is inflated so that the cord 401U is wrapped around or side-bonded to the apex rubber and the wire ring to form a composite tire bead.

[0063] It should be noted that when the above-mentioned production method is used for production, the rubber-coated steel wire ring with the triangular rubber is no longer a circular ring with a circular cross-section, but an irregular ring structure with a partial arc and a partial triangle cross-section. The ring holding transfer device 40 cannot fix and grasp the above-mentioned rubber-coated steel wire ring with the triangular rubber outside the circumference.

[0064] Therefore, in order to realize the unloading and temporary storage of the rubber-coated wire ring with the apex 100 from the bonding drum 21, as shown in FIG. Figures 14 to 16 As shown, as a second embodiment of the ring-holding transmission device 40, the ring-holding transmission device 40 includes a transmission ring body 41, the transmission ring body 41 has a hollow approximately circular structure 411 for the laminating drum 21 to pass through, the transmission ring body 41 is provided with a telescopic driving source 42 and a second synchronous transmission mechanism 43, the driving end of the telescopic driving source 42 is connected to one end of the second synchronous transmission mechanism 43, and the transmission ring body 41 is evenly provided with a plurality of supporting members 45 along the circumference of the approximately circular structure 411, the supporting members 45 can move along the radial direction of the approximately circular structure 411, and the other end of the second synchronous transmission mechanism 43 is connected to the plurality of supporting members 45. When the telescopic driving source 42 drives the second synchronous transmission mechanism 43 to rotate, the plurality of supporting members 45 are driven to approach the center of the approximately circular structure 411 or to move away from the center of the approximately circular structure 411, and when the supporting members 45 approach the center of the approximately circular structure 411, the wire ring is fixedly grasped, and when the supporting members 45 move away from the center of the circular structure 411, the wire ring is released.

[0065] Specifically, the second synchronous transmission mechanism 43 includes a plurality of first gears 436 uniformly distributed along the circumference of the approximately circular structure 411 of the transfer ring body, a synchronous belt 437 connecting the plurality of first gears 436, and a plurality of tensioning wheels 4361 arranged between the first gears. It also includes a plurality of second gears 438 and a plurality of racks 439 arranged on the side of the transfer ring body away from the first gears 436, the racks 439 are arranged along the radial direction of the approximately circular structure, the second gears 438 and the racks 439 are meshed, the first gears 436 and the second gears 438 are coaxially arranged, the end of the rack 439 close to the center of the approximately circular structure is connected to the support member 45, and the driving end of the telescopic drive source 42 is connected to the synchronous belt 437 or any first gear 436. When the telescopic driving source 42 drives the synchronous belt 437 to rotate or any first gear 436 to rotate, it drives a number of second gears 438 coaxially arranged with the first gear 436 to rotate synchronously, and drives a number of racks 439 meshing with the second gears 438 to move along the direction close to the center of the approximate circular structure or away from the center of the approximate circular structure, thereby driving a number of support members 45 to synchronously approach the center of the approximate circular structure or away from the center of the approximate circular structure. When the support members 45 approach the center of the approximate circular structure, the wire ring is fixedly grasped from outside the circumference of the wire ring, and when the support members 45 move away from the center of the approximate circular structure, the wire ring is released.

[0066] The ring transmission device 40 also includes a plurality of clamping mechanisms 46 connected to the other end of the second synchronous transmission mechanism. The clamping mechanism 46 is movably arranged on the side of the transmission ring body away from the telescopic driving source 42 through a second moving component. The clamping mechanism 46 is fixedly connected to the rack 439 through a rack connecting member 4391. The second moving component includes a first sliding rail 481 and a first slider 482 that are slidably arranged. The first slider 482 is fixedly arranged on one end of the transmission ring body away from the first gear 436. The first sliding rail 481 is fixedly arranged with the clamping mechanism 46. The first sliding rail 481 is fixedly arranged with the rack connecting member 4391. A plurality of the clamping mechanisms 46 can move synchronously with the rack 439, and a plurality of the clamping mechanisms 46 can open and close synchronously to clamp the steel wire ring with the apex rubber attached. The clamping mechanism 46 clamps the steel wire ring with the apex rubber attached from outside the circumference of the apex rubber. When the telescopic driving source 42 drives the first gear 436 to rotate, the second gear 438 coaxially arranged with the first gear 436 is driven to rotate, thereby driving the rack 439 to move relative to the transfer ring body, and then driving the clamping mechanism 46 fixedly arranged with the rack 439 to move on the transfer ring body. When it is necessary to clamp the wire ring with the apex, the several clamping mechanisms 46 are close to each other to clamp the wire ring with the apex, and when it is not necessary to clamp the wire ring, the several clamping mechanisms are far away from each other to avoid interference. Through the above arrangement, the same driving source can drive the clamping mechanism 46 to move to clamp the wire ring with the apex or drive several support members 45 to clamp the wire ring without the apex as required.

[0067] Specifically, the clamping mechanism 46 includes a first clamping plate 461 and a second clamping plate 462 which are hingedly arranged, a first clamping block 463 being detachably arranged on the first clamping plate 461, and a second clamping block 464 being detachably arranged on the second clamping plate 462, and also includes a clamping driving source 465 which is arranged on the first clamping plate 461 on a side away from the second clamping plate 462, and a driving end of the clamping driving source 465 is connected to the second clamping plate 462 through an approximately L-shaped opening and closing connecting piece 466. When the clamping driving source 465 drives the second clamping plate 462 to open and close with the first clamping plate 461, the first clamping block 463 and the second clamping block 464 are driven to approach or separate from each other, and the wire ring attached with the apex is clamped from the position of the apex by the first clamping block 463 and the second clamping block 464. The wire ring with the apex glue attached is clamped by the synchronous clamping of a plurality of clamping mechanisms 46, so as to realize unloading and temporary storage of the wire ring with the apex glue attached from the bonding drum 21. It should be noted that the number of the clamping mechanisms 46 can be consistent with the number of the supporting members 45, or inconsistent with the number of the supporting members 45, and the clamping mechanisms 46 are evenly distributed on the circumference of the approximately circular mechanism.

[0068] Preferably, the first clamping block 463 is provided with a clamping inclined surface 4631, so as to better match and clamp the second end face 102 and the third end face 103 of the apex. Through the detachable first clamping block 463 and the second clamping block 464, when the first clamping block 463 and the second clamping block 464 are worn, they can be replaced without replacing the first clamping plate 461 and the second clamping plate 462. And when producing apex of different specifications, different first clamping blocks 463 and second clamping blocks 464 can be replaced, so as to better clamp the wire ring with the apex.

[0069] Furthermore, in order to better temporarily store the steel wire ring with the apex glue attached, a plurality of magnetic elements 47 are also provided on the first clamping plate 461 near the position of the approximately circular structure. When the steel wire ring with the apex glue is clamped, the magnetic elements 47 can fix the steel wire ring by magnetic attraction, thereby better clamping the steel wire ring with the apex glue.

[0070] For tires in some special usage scenarios, the structure of the composite bead may be different. Figure 1As shown, a composite tire bead used in some aircraft tires has certain strength requirements, so a second film layer needs to be completely U-shaped bonded outside the normal composite tire bead to completely cover the apex rubber, cord fabric and steel wire ring to meet the strength requirements. For this special composite tire bead, the above equipment can also be used for production. The specific production method is that before the cord fabric 401 is cut to a fixed length and bonded to the bonding drum 21, a second film 403 is first provided through the rubber layer feeding rack 30, the second film 403 is cut to a fixed length, and the second film 403 cut to a fixed length is bonded to the bonding drum 21; then, the cord fabric 401 is provided through the rubber layer feeding rack 30, the cord fabric 401 is cut to a fixed length, and the cord fabric 401 cut to a fixed length is bonded to the bonding drum 21 bonded with the second film 403; the cloth-wrapped steel wire ring is transferred to the steel ring pre-setting device 10 by means of manual or mechanical mechanisms, and the steel ring pre-setting device 10 is used to pre-set the steel ring. The device 10 fixes and grabs the steel wire ring from the inside of the circumference of the cloth-wrapped steel wire ring; the cloth-wrapped steel wire ring is fixed and grabbed from the outside of the circumference of the cloth-wrapped steel wire ring by the ring holding transfer device 40, and the cloth-wrapped steel wire ring is moved to the bonding drum 21, and the cloth-wrapped steel wire ring is placed at a designated position on the bonding drum 21 bonded with the cord 401 and the second film 403; the apex rubber 100 is then vertically bonded to the circumference of the cloth-wrapped steel wire ring by the apex rubber vertical bonding feeding device 50; the second film 403 is completely U-wrapped and bonded to the cord 401, the apex rubber 100 and the steel wire ring by inflating the capsule on the bonding drum 21 to form a composite tire bead. Of course, before laminating the second film 403 to the laminating drum 21, the rubber-coated steel wire ring can be produced first, and the rubber-coated steel wire ring or the rubber-coated steel wire ring with the triangle rubber can be temporarily stored in the steel ring pre-setting device 10, and then subsequent production can be carried out. The specific production method is the same as the above, which will not be repeated here.

[0071] The present invention also provides a production method for forming a composite tire bead, which specifically comprises the following steps: a: The curtain fabric 401 is provided by the adhesive layer feeding rack 30, and the curtain fabric 401 is bonded to the bonding drum 21; b: Move the wire ring to the bonding drum 21 through the ring holding transfer device 40, and place the wire ring at a designated position of the bonding drum 21; c: The apex adhesive vertical pasting feeding device 50 vertically pasted the apex adhesive 100 outside the circumference of the wire ring; d: Inflate the bladder so that the cord 401 fits onto the apex 100 and the wire ring to form a composite tire bead.

[0072] When the wire ring is a cloth-wrapped wire ring, the following steps are also included before step b: e: The steel ring presetting device 10 receives the cloth-wrapped steel ring and transfers the cloth-wrapped steel ring to the ring transfer device 40; When the wire ring is a rubber-coated wire ring, the method further includes a production method for forming the rubber-coated wire ring, which includes the following steps before step a: a1: providing a first film 402 through the adhesive layer feeding rack 30, and laminating the first film 402 onto the laminating drum 21; b1: the steel ring presetting device 10 receives the bare steel ring and transfers the bare steel ring to the ring transfer device 40; c1: the ring transfer device 40 moves the bare wire ring to the bonding drum 21 and places the bare wire ring at a designated position of the bonding drum 21; d1: the capsule is inflated to cover the first film 402 on the circumference of the bare wire ring to form a rubber-coated wire ring; e1: The ring transfer device 40 unloads the rubber-coated steel wire ring from the bonding drum 21 and temporarily stores it; When the composite tire bead further includes a second film 403, the following steps are also included before step a: f: Provide the second film 403 through the glue layer supply rack 30 and laminate the second film 403 onto the laminating drum 21 .

[0073] When the wire ring is a rubber-coated wire ring, the wire ring with the apex rubber attached thereto can be temporarily stored at the ring holding transfer device 40. Correspondingly, the present invention also provides another production method for forming a composite tire bead, which includes the following steps: a1: providing a first film 402 through the adhesive layer feeding rack 30, and laminating the first film 402 onto the laminating drum 21; b1: The steel ring presetting device 10 receives the bare steel ring and transfers the bare steel ring to the ring transfer device 40; c1: The ring transfer device 40 moves the bare wire ring to the bonding drum 21 and places the bare wire ring at a designated position of the bonding drum 21; d1: the capsule is inflated to cover the first film 402 on the circumference of the bare wire ring to form a rubber-coated wire ring; c: The apex adhesive vertical pasting feeding device 50 vertically pasted the apex adhesive 100 on the outside of the circumference of the rubber-coated wire ring; e1: The ring transfer device 40 unloads the rubber-coated wire ring with the apex rubber from the bonding drum 21 and temporarily stores it; a: providing the curtain fabric 401 through the adhesive layer feeding rack 30, and laminating the curtain fabric 401 onto the laminating drum 21; b: Move the temporarily stored rubber-coated wire ring with apex glue attached to the bonding drum 21 through the ring transfer device 40, and place the rubber-coated wire ring with apex glue 100 attached to the designated position of the bonding drum 21; d: Inflate the bladder so that the cord 401 fits onto the apex rubber and the wire ring to form a composite tire bead.

[0074] The present invention mainly provides a new composite tire bead production unit. By vertically pasting apex rubber, the steel wire ring and various film layers including the reinforcement layer are directly produced on a set of equipment to produce the composite tire bead. There is no need to use multiple sets of equipment to separately produce parts and then composite production. The repeated turnover and storage of semi-finished products can be reduced, waste can be reduced, and the production cycle can be shortened. The apex rubber is directly vertically pasted on the steel wire ring through the apex rubber vertical pasting feeding device 50. There is no need to flatly paste the apex rubber on the bonding drum 21. The structure of the bonding drum 21 can be simplified. The synchronous transmission mechanism of the cam matching element 341 with a V-shaped structure and the rotating element 345 drives the clamping jaw assembly 531 to adjust the distance so as to clamp the apex rubber 100, and can clamp apex rubbers 100 of different widths; the angle adjustment mechanism 56 allows the clamping jaw assembly 531 to be parallel to the bisector of the angle formed by the second end face 102 and the third end face 103 of the apex rubber of different specifications, so as to adjust the clamping jaw. The first bonding angle of the assembly can better clamp the apex 100 of different angle specifications; when replacing the bonding drum 21 of different diameters, through three different structures of mobile compensation mechanisms, the clamping jaw assembly 531 always maintains the same second bonding angle in the circumferential section of the bonding drum 21 or keeps the clamping jaw assembly 531 always facing the center of the bonding drum 21 in the circumferential section of the bonding drum 21, thereby adjusting the second bonding angle of the clamping jaw assembly 531 to better bond the apex; through the above settings, it can better meet the production of apex or wire rings of different specifications, making the apex standing feeding device 50 more versatile. The present invention also provides a production method for forming a composite tire bead, which can bond the apex and the cord layer and the film layer to the bare wire ring, the rubber-coated wire ring or the cloth-coated wire ring to directly form a composite tire bead, which has the advantage of high production efficiency.
