[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] Please refer to Figure 1 and 8 , a conveyor device in this embodiment includes two conveyor devices 1 and a palletizing component 3 and a cutting component 2 respectively located at the two conveyor devices 1. A universal ball table 4 is fixed between the two conveyor devices 1. Lifting components 5 are installed on both the palletizing component 3 and the cutting component 2. A connecting part 7 is fixed on the conveyor device 1 at the head end, and the connecting part 7 can be docked with an external tire feeding device.

[0026] In the above structure, the pallet is transported to the stacking assembly through the head-end conveying device, and at the same time, the connecting part is connected with the external tire feeding device to guide the tire to the head-end conveying device and be located in front of the pallet. Therefore, the tire and the pallet transported by the head-end conveying device are distributed one after the other. When the tire moves to the bottom of the stacking assembly, the stacking assembly can lift the tire until the pallet moves to the position below the tire. The lifting assembly lifts up the pallet to limit the position, and then the tire is placed on the pallet. Through the cooperation of the conveying device and the universal ball table, it is transported to the cutting assembly to complete the cutting of the tire into small pieces, which is convenient for subsequent crushing.

[0027] like Figure 6 In the direction shown, the two conveying devices 1 are fixed with a pre-blocking part 6 located below the stacking assembly 3 and the cutting assembly 2. The pre-blocking part 6 includes a positioning plate 601 fixed on the two conveying devices 1, a guide cylinder 603 is fixed on the top of the positioning plate 601, and a positioning cylinder 602 is installed on the bottom. The ejection end of the positioning cylinder 602 is penetrated by the guide cylinder 603 and can extend to the top of the conveying device 1. When the tire or pallet moves under the stacking assembly and the cutting assembly, the positioning cylinder will be lifted up to block the tire or pallet, so that the tire or pallet can stay at the specified position during the conveying process. Under the action of the guide cylinder, the ejection end of the positioning cylinder can be limited to improve stability.

[0028] like Figure 7 In the direction shown, a concave plate 701 close to the stacking assembly 3 is fixed to the bottom of the conveying device 1 at the head end, four lifting columns 703 are arranged on the plate surface of the concave plate 701, and a lifting cylinder 702 is installed at the bottom of the plate surface, and a guide wheel end 704 fixed to the lifting column 703 is fixed to the ejection end of the lifting cylinder 702, and a limiting sleeve 705 is fixed to the bottom of the lifting column 703, and the guide wheel end 704 is in a concave shape and can extend to the top of the conveying device 1. The lifting column serves to improve the stability of the lifting of the guide wheel end, and the limiting sleeve can prevent the lifting column from separating from the concave plate. When the guide wheel end is lifted up by the lifting cylinder, it can be docked with the external tire delivery device, and the side of the guide wheel end will block the conveying of the pallet until the tire is transferred to the guide wheel end, and the lifting cylinder retreats, so that the tire stays on the conveying device for transportation, and the tire is located in front of the pallet.

[0029] like Figure 2-3, the palletizing assembly 3 includes a palletizing table 301 located below the head conveying device 1. A palletizing frame 302 is fixed to the top of the palletizing table 301. A pushing cylinder 303 is installed at the top of the palletizing frame 302. A pushing plate 304 slidably connected to the palletizing frame 302 is fixed to the ejecting end of the pushing cylinder 303. Two oppositely distributed moving plates 308 are slidably connected to the front surface of the pushing plate 304. Claws 309 are fixed to the opposite sides of the two moving plates 308. And pushing cylinders 310 are hinged to both of the two moving plates 308. The ejecting ends of the pushing cylinders 310 are fixedly connected to the oppositely distributed moving plates 308. When the tire stays below the two claws, in the initial state, the two moving plates and the claws are in an open state. Then the pushing cylinder drives the pushing plate to move downward, so that the tire is located between the two claws. Then the two pushing cylinders run synchronously, which can drive the two moving plates to move relatively, enabling the two claws to complete the clamping of the tire. And by driving the pushing plate to move upward through the pushing cylinder, the tire can be lifted. Until the pallet moves below, the tire is placed into the pallet to complete palletizing.

[0030] Wherein, guide wheels 306 are installed on both sides of the pushing cylinder 303 at the top of the palletizing frame 302. The inside of the guide wheel 306 is two guide gears. Chain 307 is in transmission engagement with both of the two guide gears of the guide wheel 306. The head end of the chain 307 is fixedly connected to the pushing plate 304. And a counterweight 305 slidably connected to the palletizing frame 302 is fixed between the tail ends of the two chains 307. The self-weight of the counterweight will pull the pushing plate downward through the cooperation of the guide wheel and the chain. Therefore, when the pushing cylinder drives the pushing plate to lift the tire, the load of the pushing cylinder can be reduced by the pulling of the counterweight and the chain, and the service life of the pushing cylinder can be improved.

[0031] In addition, a gear 311 is rotatably connected to the center of the pushing plate 304. Limit racks 312 meshing with the gear 311 are fixed to one ends of the two moving plates 308. The leftmost and rightmost ends of the limit rack 312 form convex plates. When the pushing cylinder drives the moving plate to operate, the limit rack will also mesh with the gear and move until the gear moves to the convex plate, which can play a limiting role to prevent the gear from separating from the limit rack.

[0032] At the same time, a sleeve block 314 is fixed to the top of the left claw 309. A servo motor 316 is installed at the top of the right claw 309. A guide air pipe 315 passing through the sleeve block 314 is fixed to the rotating end of the servo motor 316. The guide air pipe 315 is communicated with an external air guiding end. When the tire is clamped and lifted by the claw, the guide air pipe jets air to the tire. At the same time, the servo motor drives the guide air pipe to reciprocate in a fan shape, so as to increase the area of the jet air. Therefore, during the process of lifting the tire, the impurities attached to the tire can be simply cleaned.

[0033] Such as Figure 4, the cutting assembly includes a cutting table 201 located below the tail-end conveying device 1. A cutting frame 202 is fixed to the top of the cutting table 201. A linear module 203 is installed on the front of the cutting frame 202. A moving plate 204 located above the conveying device 1 is fixed to the moving end of the linear module 203. Two guiding rods 206 are passed through the moving plate 204, and a pressing cylinder 205 located between the two guiding rods 206 is installed on the top. A pressing plate 207 fixed to the guiding rods 206 is fixed to the ejecting end of the pressing cylinder 205. A cutting knife 208 is installed on the outer side of the pressing plate 207. A U-shaped plate is fixed between the tops of the two guiding rods 206. The position of the pressing plate can be adjusted through the moving plate by the linear module, and the position of the cutting knife can also be adjusted. The pressing cylinder drives the pressing plate to press down. The guiding rods play a role in guiding and limiting, enabling the pressing plate to press down stably, so that the cutting knife can complete the cutting operation on the tire.

[0034] As Figure 5 Shown in the direction, lifting components 5 are installed on both the palletizing table 301 and the cutting table 201. The lifting component 5 includes a mounting plate 501 fixed to the palletizing table 301 and the cutting table 201. Columns 503 are passed through near the four corners of the mounting plate 501. A retaining piece 504 is fixed to the bottom of the column 503. Two upward lifting cylinders 502 are installed at the bottom of the mounting plate 501. An upper top plate 505 connected to the column 502 is fixed to the ejecting end of the upward lifting cylinder 502. Support columns 506 and two buffers 508 are fixed near the four corners of the top of the upper top plate 505. Convex columns 507 that can extend to the bottom of the pallet are fixed to the tops of two of the support columns 506. When the pallet moves above the palletizing table and the cutting table, the upward lifting cylinder drives the upper top plate to lift. The columns can improve the stability of the movement of the upper top plate. At the same time, the retaining piece can prevent the column from separating from the mounting plate. When the upper top plate is lifted, the support columns will contact the bottom of the pallet to play a supporting role. Two of the convex columns will extend to the bottom of the pallet to play a limiting role to prevent movement. Then when there is a downward pressing force on the pallet, the expansion and contraction of the buffer play a buffering role.

[0035] The working principle of the above embodiment is:

[0036] First, the tray is conveyed by the head-end conveying device. At the same time, the lifting cylinder adjusts to lift the guide wheel end to block the tray, so that the tire can be conveyed in. Then the lifting cylinder retracts, placing the tire on the conveying device. The positioning cylinder rises to block the tire and the tray, positioning them at the designated position. At the same time, the upper lifting cylinder drives the upper top plate to rise, and the support column supports the convex disc while the convex column extends into the tray for limiting to prevent movement. When the tire is conveyed under the two jaws, the lower push cylinder drives the lower push plate to move down, positioning the tire between the two jaws. Then the opposing cylinder operates, driving the opposing plate to move oppositely, causing the jaws to clamp the tire. Then the lower push cylinder resets, lifting the tire. The servo motor drives the air duct to simply clean the tire until the tray moves to a suitable position below the tire. Then the tire is placed on the tray by the downward movement of the lower push cylinder and conveyed again on the conveying device. At the same time, it is transferred to the tail end in cooperation with the universal ball table and blocked again by the pre-blocking part. Then the tray is lifted and supported by the lifting assembly. Then the linear module drives the moving plate to move, enabling the pressing plate to drive the cutting knife to adjust the cutting position left and right. After the adjustment is completed, the downward pressing cylinder drives the pressing plate to press down, and the cutting knife completes the cutting of the tire. In summary, it can achieve automatic feeding of the tire, place the tire on the tray to complete the cutting operation, effectively reducing the labor intensity of workers, improving efficiency, meeting large-scale continuous production requirements, and avoiding work-related injury accidents.
