[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0031] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0032] To address the problems of long downtime and low automation in the existing technology during the feeding of rubber with steel wire, which affects tire production efficiency, this utility model provides an automatic feeding system for rubber with steel wire.

[0033] like Figures 1-8 As shown, the automatic feeding system for steel wire-lined rubber compound of this utility model includes a template device 100, a clamping device 200, a centering device 300, a rubber compound straightening device 400, and a sewing device 500. The clamping device 200 is located at the feeding end of the template device 100 and includes a clamp that can move and / or swing relative to the template device 100. The centering device 300 is located on the side of the clamping device 200 near the template device 100, and the clamp can place the rubber compound on the centering device 300. At least a portion of the rubber compound straightening device 400 is located at the end of the template device 100 away from the centering device 300, and it straightens the beginning and / or end of the rubber compound. The sewing device 500 is movably mounted on the rubber compound straightening device 400, and its sewing wheel 502 can move relative to the template device 100 to sew the beginning and end of the rubber compound after straightening by the rubber compound straightening device 400.

[0034] When using the automatic feeding system for steel-wire rubber compound of this utility model, when the feeding operation of steel-wire rubber compound needs to be performed, firstly, the clamping device places the rubber compound on the centering device through the clamp. Then, the rubber compound centered by the centering device is conveyed to the rubber compound straightening device through the template device. The rubber compound straightening device corrects the head and tail of two adjacent rubber compounds to be sewn. Finally, the sewing device, which is movably set on the rubber compound straightening device, sews the head and tail of the two rubber compounds after being corrected by the rubber compound straightening device, thereby completing the automatic feeding of rubber compound. Therefore, the automatic feeding system for steel-wire rubber compound of this application does not require manual intervention, improving tire production efficiency. Thus, the automatic feeding system for steel-wire rubber compound of this application solves the problem of long downtime and low automation in the steel-wire rubber compound feeding process of the prior art, which affects tire production efficiency.

[0035] It should be further explained that the automatic feeding system for steel wire strip rubber material of this utility model also includes an AGV trolley and a guide trolley. The AGV trolley is used to transport the guide trolley in an empty state and transport the next guide trolley loaded with steel wire strip rubber material to the workstation. When the material shortage detection device detects that the steel wire strip rubber material is empty, the AGV trolley will automatically transport the empty guide trolley and transport the next guide trolley loaded with steel wire strip rubber material to the corresponding position of the feeding equipment for conveying steel wire strip rubber material. Then, the guide trolley will guide the steel wire strip rubber material to the position connected to the clamping device. By using the AGV trolley and matching it with the guide trolley with the steel wire strip rubber material guide, the manual operation of transferring material carts is avoided. The entire operation can be automated, greatly improving the level of intelligence and helping to improve work efficiency.

[0036] Specifically, the clamping device 200 is set at the feeding end of the template device 100, and the clamping device 200 includes an upper clamping plate 201, a lower clamping plate 202, a material head detection switch 203, an upper clamping plate cylinder 204, a clamping plate swing cylinder 205, a clamping plate moving cylinder 206, a swing arm 207, a proximity switch 208, a sensing plate 209, a limit bolt 210, a bearing 211, a drive motor 212, a bracket 213, a moving cylinder 214, and a drive shaft 215. The lower clamping plate 202 is fixedly set on the bracket 213, and a swing arm 207 is set on one side of the bracket 213. The swing arm 207 is rigidly connected to the drive shaft 215, and the swing arm 207 and the bracket 213 can be rotatably connected through the bearing 211. A drive motor 212 is provided on the side of the bracket 213 opposite to the swing arm 207. The drive motor 212 can drive the swing arm 207 to swing through the drive shaft 215, thereby driving the material clamps, including the upper clamping plate 201 and the lower clamping plate 202, to swing. A moving cylinder 214 is provided at the lower part of the bracket 213 and is used to drive the bracket 213 to move in a specified direction.

[0037] During operation, the material head with steel wire enters between the upper clamping plate 201 and the lower clamping plate 202. When the material head detection switch 203 detects the material head, the upper clamping plate cylinder 204 located at the top of the bracket 213 drives the upper clamping plate 201 to move downward, clamping the material head with steel wire together with the lower clamping plate 202. Then, the drive motor 212 drives the swing arm 207 to swing to the vertical position through the drive shaft 215. Specifically, the bracket 213 is also equipped with a proximity switch 208, and the swing arm 207 is equipped with a sensing plate 209. The swing position of the swing arm 207 is determined by the sensing plate 209 and the proximity switch 208. The bracket 213 can also be equipped with a limit bolt 210 to limit the swing arm 207 from continuing to rotate after rotating to this position. When the swing arm 207 moves to the designated position, the moving cylinder 214 drives the material clamp to move horizontally between the template device 100 and the mechanical centering device 300. At this time, the clamping plate moving cylinder 206 drives the material clamp to move downward, moving the material head with steel wire rubber to the conveying surface of the template device 100.

[0038] Specifically, the template device 100 includes a first conveyor belt 110 and a second conveyor belt 120 connected in sequence. A clamping device 200 is located at the end of the first conveyor belt 110 away from the second conveyor belt 120. At least a portion of the centering device 300 is located on the first conveyor belt 110, and at least a portion of the adhesive straightening device 400 is located above the second conveyor belt 120. The template device 100 also includes a magnetic suction assembly 130, at least a portion of which is movably disposed inside the second conveyor belt 120 corresponding to the adhesive straightening device 400. The magnetic suction assembly 130 includes a magnetic suction part 131, which is movable relative to the second conveyor belt 120. Because the adhesive contains steel wire, when positioning the head and tail of two pieces of adhesive to be sewn, the magnetic suction assembly 130 located inside the second conveyor belt 120 can attract the head and tail of the adhesive respectively, thereby achieving magnetic positioning of the adhesive and ensuring the sewing effect of the head and tail. Meanwhile, the magnetic suction assembly 130 is located inside the second conveyor belt 120, which avoids interference between the magnetic suction assembly 130 and the adhesive straightening device 400 and the sewing device 500.

[0039] Specifically, the magnetic suction assembly 130 further includes a magnetic suction slide rail 132 and a first drive unit 134. The magnetic suction slide rail 132 is disposed inside the second conveyor belt 120, and the magnetic suction unit 131 has a groove 133 that cooperates with the magnetic suction slide rail; at least a portion of the first drive unit 134 is disposed outside the second conveyor belt 120, and at least another portion of the first drive unit 134 is disposed inside the second conveyor belt 120 and is drivenly connected to the magnetic suction unit 131, so that the magnetic suction unit 131 can move along the magnetic suction slide rail 132. Preferably, the magnetic suction slide rail 132 has an arc-shaped section, and the magnetic suction unit 131 moves along the arc-shaped section. By setting the magnetic suction slide rail 132, the magnetic suction unit can move along the arc-shaped section, thereby enabling the position adjustment of the magnetic suction unit, which in turn allows the magnetic suction unit to be aligned with the connection point of the beginning and end of the two adhesive materials, making the subsequent sewing process more accurate.

[0040] In one specific embodiment of this application, the magnetic suction unit 131 includes a magnetic suction bracket 135, a plurality of magnets 136, and a second drive unit 137. The magnetic suction bracket 135 has a groove 133 that cooperates with the magnetic suction slide rail 132; the plurality of magnets 136 are divided into two groups, the two groups of magnets 136 are arranged in parallel directions and have an angle greater than 0 degrees and less than 90 degrees with respect to the running direction of the second conveyor belt 120; at least a portion of the second drive unit 137 is disposed on the magnetic suction bracket 135 and is drivenly connected to all the magnets 136, so that the magnets 136 can move along the side of the second conveyor belt 120 that is close to or away from the side that is close to the rubber material straightening device 400. Therefore, when it is necessary to magnetically fix the head and tail of the material located on the second conveyor belt 120, the first drive unit 134 drives the magnetic attraction unit 131 to move along the magnetic attraction rail 132 to below the head and tail of the material. At this time, the second drive unit 137 drives the magnet 136 to move in the direction close to the second conveyor belt 120. Since the multiple magnets are divided into two groups, the head and tail of the material can be attracted by the two groups of magnets respectively, so that the head and tail of the material can be attracted to the second conveyor belt 120, thereby preventing the head and tail of the material from moving during the sewing process and effectively ensuring the sewing effect of the head and tail of the material.

[0041] In one specific embodiment of this application, the first driving unit 134 may include a handwheel 1341, a lead screw 1342, a lead screw nut 1343, a spherical bearing 1344, and a connecting plate 1345. The handwheel 1341 is connected to the magnetic suction unit 131 through the lead screw 1342, the lead screw nut 1343, the spherical bearing 1344, and the connecting plate 1345. During use, rotating the handwheel 1341 drives the lead screw 1342, which is fixedly connected to it, to rotate. This, in turn, drives the lead screw nut 1343 located on the lead screw 1342 to move along the lead screw 1342. Finally, the magnetic suction unit 131 moves along the magnetic suction slide rail 132 through the spherical bearing 1344 and the connecting plate 1345. The second drive unit 137 can be a pneumatic cylinder or a hydraulic cylinder. The second drive unit 137 is connected to multiple piston structures through a pneumatic or hydraulic passage. Multiple magnets 136 are located at the heads of multiple piston structures. Thus, multiple pistons can be simultaneously controlled to reciprocate through the pneumatic or hydraulic cylinder, thereby driving the magnets 136 located at the piston heads to move in a direction close to or away from the second conveyor belt 120.

[0042] In some embodiments, the template device 100 further includes a transition plate 140, through which the first conveyor belt 110 and the second conveyor belt 120 are connected. The surface of the transition plate 140 is provided with air blowing holes 141 capable of blowing gas outward. With the above arrangement, the steel wire rubber material will not get stuck when passing through the transition plate 140 due to the air blowing action.

[0043] Specifically, the centering device 300 includes a first centering component 310 and a second centering component 330. At least a portion of the first centering component 310 is disposed on the first conveyor belt 110; the second centering component 330 is disposed between the first centering component 310 and the clamping device 200, and the clamping device is capable of placing the adhesive material between the first centering component 310 and the second centering component 330. The direction in which the first centering component 310 conveys the adhesive material has an angle greater than 0 degrees with the direction in which the second centering component 330 conveys the adhesive material. Through the first centering component 310 and the second centering component 330, the adhesive material can be pushed towards the center along the conveying direction to ensure more accurate subsequent correction of the material head and tail. Furthermore, after the adhesive material is placed on the first conveyor belt, the first and second centering components can be used to position the adhesive material, thereby ensuring that the length direction of the adhesive material is the same as the length direction of the first conveyor belt, and thus ensuring that the adhesive material does not deviate during the conveying process of the first conveyor belt. In other words, the first centering component and the second centering component in this application limit the conveying direction of the rubber material, ensuring that the rubber material will not gradually form an angle with the movement direction of the first conveyor belt as it is gradually conveyed to the first conveyor belt.

[0044] Specifically, the first centering assembly 310 includes a first mounting frame 311, a centering plate 312, a third drive unit, and a pressure roller 313. The first mounting frame 311 has a positioning space through which the first conveyor belt 110 passes; there are two centering plates 312, which are movably disposed within the positioning space and are parallel to each other; the third drive unit is disposed on the first mounting frame 311 and is drivenly connected to the two centering plates 312 respectively, so that the two centering plates 312 can move in a direction that approaches or moves away from each other; the pressure roller 313 is movably disposed on the side of the first mounting frame 311 near the second centering assembly 330, and the pressure roller 313 can move in a direction that approaches or moves away from the first conveyor belt 110. For example, the pressure roller 313 can be movably mounted on the side of the first mounting frame 311 by a cylinder 314, and the cylinder 314 drives the pressure roller to move in a direction that approaches or moves away from the first conveyor belt 110. The pressure roller 313 presses the steel wire rubber material onto the first conveyor belt 110, allowing the steel wire rubber material to be conveyed forward along the first conveyor belt 110. The first centering component 310 makes the conveying of the steel wire rubber material on the first conveyor belt 110 more stable and reliable.

[0045] The third drive unit may include a first drive member 315, a first lead screw 316, a first lead screw nut 317, a second lead screw 318, a second lead screw nut 319, and a first connecting member 320. The first drive member 315 is fixedly mounted on the first mounting bracket 311. The first lead screw nut 317 is movably mounted on the first lead screw 316, and the second lead screw nut 319 is movably mounted on the second lead screw 318. The first lead screw nut 317 and the second lead screw nut 319 move in directions that are closer to or further away from each other. The first lead screw 316 and the second lead screw 318 are connected via the first connecting member 320. The first drive member 315 is driven to the end of the first lead screw 316 away from the second lead screw 318 and drives the first lead screw 316 to rotate. The first lead screw nut 317 is fixedly connected to one of the two centering plates 312, and the second lead screw nut 319 is fixedly connected to the other of the two centering plates 312. It should be noted that in this embodiment, the first driving component 315 can be a motor and a synchronous pulley driven by the motor. The synchronous pulley can drive the first lead screw 316 to rotate. Since the first lead screw 316 and the second lead screw 318 are connected by the first connecting component 320, the first lead screw 316 can drive the second lead screw 318 to rotate. At the same time, since the first nut 317 and the second nut 319 move in directions that are closer to or further away from each other, they can drive the two centering plates to move in directions that are closer to or further away from each other, thereby realizing the adjustment of the distance between the two centering plates 312. Of course, in this application, a handwheel or the like can also be used as a driving component to drive the first lead screw 316. Optionally, the first connecting component 320 in this utility model is a coupling.

[0046] Specifically, the second centering assembly 330 includes a second mounting frame 331, multiple centering rollers 332, and a fourth drive unit. The multiple centering rollers 332 are divided into two groups, each group movably mounted on the second mounting frame 331, with each group positioned on one side of the rubber material. The fourth drive unit is driven to each of the two groups of centering rollers 332, allowing them to move towards or away from each other. The line connecting the end of each centering roller 332 to the fourth drive unit forms an angle with the conveying direction of the first conveyor belt 110. By achieving rolling contact between the centering rollers 332 and the edge of the forward-conveyed steel wire rubber material, the frictional resistance of the forward conveying of the steel wire rubber material is reduced, resulting in smoother conveying.

[0047] The fourth drive unit may include a second drive member 333, a third lead screw 334, a third lead screw nut 335, a fourth lead screw 336, a fourth lead screw nut 337, and a second connecting member 338. The second drive member 333 is fixedly mounted on the second mounting bracket 331, the third lead screw nut 335 is movably mounted on the third lead screw 334, and the fourth lead screw nut 337 is movably mounted on the fourth lead screw 336. The third lead screw nut 335 and the fourth lead screw nut 337 can move in directions that are closer to or further away from each other. The third lead screw 334 and the fourth lead screw 336 are connected by the second connecting member 338.

Since the third lead screw 334 and the fourth lead screw 336 are connected by the second connecting member 338, the third lead screw 334 can drive the fourth lead screw 336 to rotate. Since the first and second lead screw nuts move in directions that bring them closer together or further apart, the first movable plate 339 and the second movable plate 340 can also move in directions that bring them closer together or further apart, thereby adjusting the distance between the two sets of centering rollers 332. Of course, in this application, a handwheel or similar device can also be used as a driving component to drive the third lead screw 334. Optionally, in this invention, the second connecting member 338 is a coupling.
