[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0031] like Figures 1 to 14 As shown, the present invention discloses a apex adhesive standing feeding device 1, comprising a support seat 10, a limit support mechanism 20 rotatably arranged on the support seat 10, the limit support mechanism 20 is used to provide support and limit for the apex adhesive 100 when the apex adhesive 100 is bonded to a wire ring 300 located on a bonding drum 200; a clamping mechanism 30 arranged on the limit support mechanism 20 at one end away from the support seat 10, the clamping mechanism 30 has a clamping jaw assembly 31 with adjustable spacing, and the clamping jaw assembly 31 is used to clamp the apex adhesive; it also includes a swing driving source 40 arranged on the support seat 10, the driving end of the swing driving source 40 is connected to the end of the limit support mechanism 20 close to the support seat 10, and the swing driving source 40 is used to drive the limit support mechanism 20 to rotate around the support seat 10, thereby driving the clamping jaw assembly 31 connected to the limit support mechanism 20 to avoid the bonding drum or to bond the apex adhesive close to the bonding drum.

[0032] According to the above arrangement, when the apex is attached, the apex is clamped by the distance-adjustable clamping jaw assembly 31, and the swing driving source 40 drives the limit support mechanism 20 to rotate counterclockwise, thereby driving the clamping jaw assembly 31 to move the apex 100 to the attaching drum 200, and lightly press the apex 100 onto the wire ring 300 on the attaching drum 200. As the attaching drum 200 rotates, the apex 100 is attached to the circumference of the wire ring 300. The apex vertical attaching feeding device of the present invention is mainly used for feeding and attaching apex that has been cut to a fixed length. Of course, the rolled apex 100 can also be attached to the wire ring and then cut to a fixed length.

[0033] like Figure 1 As shown, the support seat 10 of the present invention is connected to the position-limiting support mechanism 20 through a support shaft 11, and the support shaft 11 is arranged on the support seat 10. The position-limiting support mechanism 20 is rotatably arranged on the support shaft 11 through a first bearing member (not shown). The position-limiting support mechanism 20 has a first end 21, a second end 22 and a fulcrum portion 201, the support seat 10 is connected to the fulcrum portion 201 of the position-limiting support mechanism, the swing drive source 40 is connected to the first end 21 of the position-limiting support mechanism, the clamping mechanism 30 is connected to the second end 22 of the position-limiting support mechanism, and the position-limiting support mechanism 20 is tiltedly arranged on the support seat 10, and the distance between the first end 21 of the position-limiting support mechanism and the fulcrum portion 201 is smaller than the distance between the second end 22 of the position-limiting support mechanism and the fulcrum portion 201, so that the position-limiting support mechanism 20 and the support seat 10 form a lever connection. Through the above arrangement, the swing drive source 40 only needs to drive the first end 21 of the limit support mechanism to move a small distance in the vertical direction, and the moving distance of the second end 22 of the limit support mechanism in the vertical direction will be proportionally enlarged, which can effectively save space.

[0034] like Figure 2 As shown, the limit support mechanism 20 described in the present invention includes a first side plate 23 and a second side plate 24 arranged in parallel, and a bottom plate 25 arranged perpendicular to the first side plate 23 and the second side plate 24, respectively. A plurality of feed rollers 26 are arranged in parallel between the first side plate 23 and the second side plate 24, and the feed rollers 26 are used to support the apex. The limit support mechanism 20 also includes a plurality of guide roller groups arranged on the bottom plate 25, and the guide roller groups have guide rollers 27 arranged in pairs. When the bonding drum rotates to drive the apex to move, the guide rollers 27 are used to guide and limit the apex.

[0035] When producing apex adhesives of different widths, the distance between the paired guide rollers 27 also needs to be adjusted accordingly, otherwise the laminating quality will be affected when the apex adhesive swings greatly during the laminating process. In order to more accurately guide and limit apex adhesives of different widths, the limiting support mechanism 20 of the present invention also includes a spacing adjustment mechanism 28, and the spacing adjustment mechanism 28 is used to adjust the spacing between the paired guide rollers 27. Specifically, the spacing adjustment mechanism 28 includes a group of guide connecting blocks 282 movably arranged on the bottom plate 25 through a first moving component (not shown), the paired guide rollers 27 are respectively arranged on two guide connecting blocks 282, and also include positive thread screw nuts 283 and reverse thread screw nuts 284 respectively arranged on the two guide connecting blocks 282, and a screw 285 rotatably arranged on the first side plate 23 and the second side plate 24, the positive thread screw nuts 283 and reverse thread screw nuts 284 are respectively arranged at the two ends of the screw 285 through threaded connection, and also include a first adjustment member 286 arranged at one end of the screw 285. The first adjusting member 286 can be a manual handle or a driving source, which drives the screw rod 285 to rotate manually or automatically, driving the positive thread screw nut 283 and the negative thread screw nut 284 threaded on the screw rod 285 to move closer to or away from each other, thereby driving the two guide connecting blocks 282 to move closer to or away from each other, and driving the paired guide rollers 27 arranged on the guide connecting blocks 282 to move closer to or away from each other, so as to adapt to apex rubbers of different widths.

[0036] like Figure 1 and 3 As shown, the clamping mechanism 30 described in the present invention includes a mounting plate 32, a mobile driving source 33 and a synchronous transmission mechanism 34 arranged on the mounting plate 32, the other end of the synchronous transmission mechanism 34 is connected to the clamping jaw assembly 31, and the mobile driving source 33 adjusts the distance between the clamping jaw assemblies 31 through the synchronous transmission mechanism 34.

[0037] Preferably, the clamping jaw assembly 31 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 transported forward through the bonding drum, 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.

[0038] like Figures 3 to 5As shown, the synchronous transmission mechanism 34 of the present invention includes a cam matching element 341 arranged at the driving end of the mobile driving source 33, 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 32 through a second 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, the A rotating shaft 344 is installed on the first end 3431, and a rotating element 345 is rotatably installed on the rotating shaft 344. The two rotating elements 345 are respectively contacted 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 installation 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 32. The cam mating element 341 is driven to move by the mobile driving source 33, so that the two rotating elements 345 are arranged in contact with 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.

[0039] like Figure 5 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.

[0040] like Fig.10 and 11As 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 is an arc surface that matches the wire ring 300, and the second end face 102 and the third end face 103 are inclined surfaces. The angles formed by the second end face 102 and the third end face 103 of the apex 100 of different specifications are different, including Fig.10 The isosceles triangle formed by the second end face 102 and the third end face 103 of the apex shown in b1, and the non-isosceles triangle formed by the second end face 102 and the third end face 103 of the apex shown in b2. The clamping mechanism 30 is clamped and fixed 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 31 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 300.

[0041] like Fig.10 and 11 As shown, in order to better meet the requirements of laminating apex 100 of different angles on the wire ring 300, the apex vertical laminating feeding device of the present invention also includes an angle adjustment mechanism 60, so as to set the first laminating angle of the clamping jaw assembly 31, and the first laminating angle is the angle of the clamping jaw assembly 31 in a plane coplanar with the axial cross section Q of the laminating drum. Through the first laminating angle setting, the angle bisector 104 of the angle formed by the clamping jaw assembly 31, the second end face 102 of the apex and the third end face 103 of the apex is set in parallel. Wherein b1 is when the second end face 102 of the apex and the third end face 103 of the apex are isosceles triangles, the clamping jaw assembly 31 clamps the apex 100 to be vertically laminating the wire ring 300 located on the laminating drum 200. b2 represents that when the second end face 102 and the third end face 103 of the apex are non-isosceles triangles, the clamping jaw assembly 31 adjusts the first fitting angle through the angle adjustment mechanism 60, so that the clamping jaw assembly 31 clamps the apex rubber 100 in a direction parallel to the angular bisector a3 of the angle formed by the second end face 102 and the third end face 103 of the apex rubber to fit the wire ring 300 located on the fitting drum 200.

[0042] like Figure 6As shown, the material clamping mechanism 30 of the present invention is arranged on the position limiting support mechanism 20 through a connecting bracket 70 . Specifically, the angle adjustment mechanism 60 described in the present invention includes two groups of hinge mechanisms 61, and the two groups of hinge mechanisms 61 are respectively connected to the clamping mechanism 30 and the connecting bracket 70, specifically connected to the mounting plate 32 on the clamping mechanism 30, the hinge mechanism 61 includes a first hinge 611 and a second hinge 612 that are hingedly arranged, a hinge shaft 613 is fixedly arranged on the first hinge 611, and the second hinge 612 is rotatably arranged on the hinge shaft 613 through a second bearing member (not shown); the angle adjustment mechanism 60 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 70 and are connected to one group of the hinge mechanisms 61, the length adjustment member 6151 is used to adjust the height of the first hinge 611 and the connecting bracket 70, and the fastener 6152 is used to fix the connecting bracket 70 and the first hinge 611. When the height of one set of hinge mechanisms 61 is adjusted by the length adjusting member 6151 and the fastener 6152, the height of the other set of hinge mechanisms 61 remains unchanged, and the height difference formed by the two sets of hinge mechanisms 61 causes the material clamping mechanism 30 to be tilted, thereby driving the clamping claw assembly 31 on the material clamping mechanism 30 to tilt. And because the first hinge seat 611 and the second hinge seat 612 are hingedly arranged, when the material clamping mechanism 30 tilts, although the position of one set of the hinge mechanisms 61 is raised, the first hinge seat 611 is still stably connected to the connecting bracket 70 without tilting, thereby ensuring the stability of the connection setting.

[0043] The height adjustment of the hinge mechanism 61 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 60 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 70 and the first hinge 611, and a lifting drive source (not shown). The lifting drive source is arranged on the connecting bracket 70, 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 70 by the lifting drive source, and is guided to move linearly by the linear bearing mechanism, so that one group of first hinges 611 is lifted relative to the connecting bracket 70.

[0044] like Figure 3 and 4As shown, in order to more reasonably arrange the clamping mechanism 30 and the angle adjustment mechanism 60, the mounting plate 32 of the present invention comprises a first mounting plate 321 and a second mounting plate 322 arranged in interval connection, wherein the second mounting plate 322 is provided with a notch 3221, the mobile driving source 33 is arranged on the first mounting plate 321, and the cam mounting member 343 is movably arranged on the first mounting plate 321 through the notch 3221 on the second mounting plate, so that the rotating element 345 is formed between the first mounting plate 321 and the second mounting plate 322. In the space, specifically, the second installation end 3432 of the cam mounting member 343 is movably arranged on the first mounting plate 321, and the first installation end 3431 of the cam mounting member is located below the second mounting plate 322, and the cam mating element 341 is arranged between the first mounting plate 321 and the second mounting plate 322, and is arranged in contact with the rotating element 345 in the space formed by the first mounting plate 321 and the second mounting plate 322, and the second hinge seat 612 on the angle adjustment mechanism is detachably arranged on the second mounting plate 322.

[0045] When producing wire rings 300 of different diameters, the diameter of the bonding drum 200 used is also different, that is, the height position of the clamping jaw assembly 31 to place the apex 100 on the wire ring 300 is also different. Therefore, when the swing drive source 40 of the present invention drives the limit support mechanism 20 to rotate around the support shaft 11, in addition to driving the clamping jaw assembly 31 away from the bonding drum 200 or close to the bonding drum 200, it is also used to adjust the height of the clamping jaw assembly 31 to be suitable for bonding drums 200 of different diameters, thereby producing wire rings 300 of different specifications. It should be noted that, if Fig.12 As shown, when the jaw assembly 31 clamps the apex rubber 100 to fit on the bonding drum 200, the angle of the jaw assembly 31 in the plane coplanar with the circumferential radial section P of the bonding drum 200 is the second bonding angle. The first bonding angle and the second bonding angle of the jaw assembly 31 form the bonding angle of the apex rubber 100 on the bonding drum 200. Usually, corresponding to tires with different outer diameters, the size of the second bonding angle also needs to be adjusted. In order to simplify the debugging and production of bonding drums 200 with different diameters, after the debugging of the second bonding angle of the jaw assembly 31 clamping the apex rubber 100 and the bonding drum 200 is completed, when the bonding drum 200 with a different diameter is replaced, the jaw assembly 31 can be kept to bond at the same second bonding angle. After replacing a different bonding drum, in the process of the swing drive source 40 driving the limit support mechanism 20 to rotate around the support shaft 11, the clamping mechanism 30 can keep the original second bonding angle unchanged by setting a movement compensation mechanism. As shown Fig.12As shown, when the bonding drum 200A is replaced by 200B, the swing drive source 40 drives the limit support mechanism 20 to rotate clockwise around the support shaft 11, and the clamping jaw assembly 31 always remains vertically downward in the circular cross-section of the bonding drum 200, that is, the second bonding angle of the clamping jaw assembly 31 remains unchanged.

[0046] like Figures 7 to 9 As shown in 12, as a first embodiment to achieve the above technical effects, the support shaft 11 is fixedly arranged on the support seat 10, and the support shaft 11 and the support seat 10 can be arranged integrally or separately, and a first fixed shaft 71 is rotatably arranged on one end of the limiting support mechanism 20 close to the connecting bracket 70, and the connecting bracket 70 is fixedly arranged on the first fixed shaft 71, and the movement compensation mechanism is a sprocket and chain structure, specifically including a first sprocket 82 and a second sprocket 83 connected by a chain 81, and the first sprocket 82 is fixedly arranged on the support shaft 11, and the second sprocket 83 is fixedly arranged on the first fixed shaft 71. When the swing drive source 40 drives the limit support mechanism 20 to rotate around the support shaft 11, the limit support mechanism 20 as a whole rotates with the support shaft 11 as the rotation center. Since the support shaft 11 is fixedly set on the support seat 10 and does not rotate, the first sprocket 82 fixedly set with the support shaft 11 does not rotate, and the second sprocket 83 connected to the first sprocket 82 through the chain 81 does not rotate. Therefore, the connecting bracket 70 fixedly set with the second sprocket 83 through the first fixed shaft 71 does not rotate either. That is, although the clamping jaw assembly 31 follows the position of the limit support mechanism 20 around the support shaft 11 in a plane (the plane is coplanar with the circumferential radial section P of the bonding drum) and moves horizontally, the angle of the clamping jaw assembly 31 in the plane always remains unchanged. Therefore, when using bonding drums 200 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.

[0047] Of course, in order to achieve the best fitting quality between the apex 100 and the wire ring 300, when the clamping jaw assembly 31 is arranged in the circumferential radial section P of the bonding drum 200 toward the center direction of the bonding drum 200, the fitting quality between the apex 100 and the wire ring 300 is the best. Fig.13As 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 84, and the compensation drive source 84 is independently arranged or arranged on the limiting support mechanism 20, and the driving end of the compensation drive source 84 is connected to the first fixed shaft 71. When the bonding drum is replaced from 200A to 200B, the swing drive source 40 drives the limit support mechanism 20 to rotate around the support shaft 11 in the clockwise direction at a first angle, and drives the clamping mechanism 30 to rotate at the same angle. Then, the compensation drive source 84 drives the connecting bracket 70 to rotate in the counterclockwise direction (i.e., the direction opposite to the rotation direction of the limit support mechanism 20) 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 30 rotates with the limit support mechanism 20, thereby ensuring that the clamping mechanism 30 maintains the original angle unchanged within the circular cross-section of the bonding drum 200; the second angle can also be directly set so that the clamping claw assembly 31 in the clamping mechanism 30 remains set toward the center direction of the bonding drum 200 within the circular cross-section of the bonding drum 200. At this time, the second angle may be the same as the first angle, or it may be different from the first angle.

[0048] like Fig.14The 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 11 is rotatably arranged on the support seat 10. In addition to the sprocket and chain structure, the mobile compensation mechanism specifically includes a first sprocket 82 and a second sprocket 83 connected by a chain 81. The first sprocket 82 is fixedly arranged on the support shaft 11, and the second sprocket 83 is fixedly arranged on the first fixed shaft 71. The mobile compensation mechanism also includes a handle and a brake (not shown) arranged on the support shaft 11. The handle is used to drive the support shaft 11 to rotate, and the brake is used to fix the rotation position of the support shaft 11 to prevent the support shaft 11 from rotating at will. When the bonding drum 200A is replaced by 200B, the swing drive source 40 drives the limit support mechanism 20 to rotate around the support shaft 11 in the clockwise direction by a first angle, and the support shaft 11 is braked and does not rotate, so the first sprocket 82 fixed to the support shaft 11 does not rotate, and the second sprocket 83 connected to the first sprocket 82 through the chain 81 does not rotate, so the connecting bracket 70 fixed to the second sprocket 83 through the first fixed shaft 71 does not rotate, that is, the clamping jaw assembly 31 follows the limit support mechanism 20 to rotate in the plane around the support shaft 11. The brake member 11 is then released to rotate through the handle, thereby driving the first sprocket 82 fixed to the support shaft 11 to rotate, and the second sprocket 83 is driven to rotate through the chain 81, thereby driving the first fixed shaft 71 fixed to the second sprocket 83 to rotate, thereby driving the connecting bracket 70 fixed on the first fixed shaft 71 to rotate, and driving the clamping jaw assembly 31 to rotate in the circumferential radial section P of the bonding drum 200 toward the center 200C of the bonding drum.

[0049] That is to say, when replacing the bonding drum 200 of different sizes, the clamping mechanism 30 can maintain the second bonding angle of the clamping mechanism 30 unchanged within the circumferential radial section P of the bonding drum 200 by setting a moving compensation mechanism to facilitate the change of model and debugging, or the second bonding angle of the clamping mechanism 30 can be changed by the moving compensation mechanism, but the clamping mechanism 30 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.

[0050] Furthermore, in order to prevent the apex 100 from contacting the second sprocket 83 or the first fixed shaft 71 during the bonding and conveying process, thereby damaging the apex 100, the connecting bracket 70 of the present invention is further provided with a plurality of transition rollers 72 for limiting position.

[0051] like Figure 1The apex rubber standing feeding device described in the present invention also includes a mounting seat 90, and the support seat 10 is movably arranged on the mounting seat 90, so that the support seat 10 can move along the axial direction of the bonding drum 200, thereby being able to move along the axial direction of the bonding drum 200 with the clamping jaw assembly 31 holding the apex rubber 100, thereby bonding the apex rubber 100 to the wire ring 300 located at different positions of the bonding drum 200.

[0052] It should be noted that when the apex adhesive standing feeding device 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 300 manually or automatically by other mechanical structures, and the apex adhesive 100 is clamped by the clamping claw assembly 31, and then the swing driving source 40 drives the limiting support mechanism 20 to rotate in the direction close to the bonding drum 200, so that the clamping claw assembly 31 clamps the apex adhesive 100 and makes it conflict with the wire ring 300 (the conflict described in the present invention refers to the apex adhesive 100 being lightly pressed on the wire ring 300, but does not affect the rotation of the bonding drum 200), and then the bonding drum 200 rotates, driving the apex adhesive 100 to be bonded to the wire ring 300 to complete the standing bonding of the apex adhesive.

[0053] The present invention mainly provides a new apex adhesive vertical pasting feeding device, which is used to deliver the apex adhesive 100 clamped by the clamping jaw assembly 31 to the wire ring 300 of the bonding drum 200, and cooperate with the rotation of the bonding drum 200 to directly bond the apex adhesive vertically; the clamping jaw assembly 31 is driven by a synchronous transmission mechanism with a cam matching element 341 and a rotating element 345 having a V-shaped structure to adjust the distance so as to clamp the apex adhesive 100, and the apex adhesive 100 of different widths can be clamped; the clamping jaw assembly 31 can form an angle adjustment mechanism 60 with the second end face 102 and the third end face 103 of the apex adhesive of different specifications The bisectors of the angle are kept parallel, so as to adjust the first bonding angle of the clamping jaw assembly in the plane coplanar with the axial section of the bonding drum, so as to better clamp the apex 100 of different angle specifications; when replacing the bonding drum 200 of different diameters, through three different structures of mobile compensation mechanisms, the clamping jaw assembly 31 always maintains the same second bonding angle in the plane coplanar with the circumferential radial section of the bonding drum 200 for easy replacement, or keeps the clamping jaw assembly in the plane coplanar with the circumferential radial section of the bonding drum 200 always facing the center of the bonding drum 200, so as to adjust the second bonding angle of the clamping jaw assembly, so as to better bond the apex. Through the above settings, the production of apex or wire rings of different specifications can be better met, making the apex standing feeding device more versatile.

Any equivalent changes or replacement technical solutions that can be easily thought of by any person skilled in the art under the inspiration of the technical content of the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
