[0047] See also Figure 1-Figure 12 As shown, the present invention provides a tire stacking robot for recycling waste tires, comprising a plurality of stacking racks 100 arranged side by side, a rubber belt 150 sleeved on the outside of the stacking racks 100, a plurality of tire placing parts 200 clamped on the outer wall of the rubber belt 150, and a servo motor 160 for driving the rubber belt 150 to circulate up and down; a pair of tire unloading parts 300 for controlling the tire placing parts 200 to automatically unload tires are arranged in the top of the stacking rack 100; a worker places waste tires on the tire placing parts 200 in front of the stacking rack 100, and the servo motor 160 drives the rubber belt 150 to transport each row of the plurality of tire placing parts 200 holding waste tires of different specifications to the rear of the stacking rack 100, and the correspondingly arranged tire unloading parts 300 trigger the tire placing parts 200 to automatically unload the tires and stack them;

[0048] The tire placement part 200 includes a support plate 210 attached to the rubber belt 150, support rods 220 inserted at the four corners of the support plate 210, and a plurality of adjustment rods 230 used to drive the plurality of support rods 220 to move horizontally, so as to adjust the spacing between the support rods 220 between levels to adapt to the placement of tires of different sizes; the end of the adjustment rod 230 is sleeved with a rod sleeve 231 sleeved with the support rod 220, and the adjustment rod 230 and the rod sleeve 231 rotate relative to each other, so that the support rod 220 can be driven by the rod sleeve 231 to move horizontally, and at the same time move along the central axis direction of the rod sleeve 231, so that the support plate 210 loses its support for the tire;

[0049] The width of the support plate 210 is greater than the width of the rubber belt 150, and rod grooves 113 are provided on the rear side of the stacking rack 100 and on both sides of the rubber belt 150, so that the support rod 220 is located outside the rubber belt 150 and plugged into the rod groove 113, and then retreated into the stacking rack 100 and hidden; the rod groove 113 is vertically arranged and the tire unloading part 300 is correspondingly arranged on the inner side of the top of the rod groove 113, so that the tire placing part 200 starts to unload and stack the tires from the top of the rod groove 113.

[0050] Specifically, the tire unloading part 300 includes a magnetic member 310 disposed toward the rod groove 113 and a telescopic tube 320 for supporting the magnetic member 310; the telescopic tube 320 controls the height position of the magnetic member 310 by extending and retracting up and down for storage and processing; the magnetic member 310 is composed of a guide rod magnetic plate 311 and a magnetic block 312 that are hingedly connected; the guide rod magnetic plate 311 is inclined and located above the top of the rod groove 113; a magnetic strip is embedded on the inclined bottom surface of the guide rod magnetic plate 311, and the magnetic strip is embedded on the inclined bottom surface of the guide rod magnetic plate 311. A magnetic block is embedded in the side of the suction block 312 facing the rod groove 113; the rear end of the support rod 220 is an iron block and the outer diameter is larger than the rod diameter, so as to prevent the support rod 220 from slipping forward; that is, the guide rod magnetic plate 311 is used to magnetically attract and guide the support rod 220 to move toward the magnetic suction block 312 without contacting the support rod 220, and the distance between the magnetic suction block 312 and the inner wall of the stacking rack 100 is larger than the length of the support rod 220; and thus the support rod 220 is completed when retreating into the interior of the stacking rack 100 without contacting and magnetically attracting the magnetic suction block 312;

[0051] Since the rubber belt 150 is constantly moving, when the support rod 220 is sucked in front of the magnetic block 312, it will continue to be driven downward by the rubber belt 150 and demagnetized from the magnetic block 312 until the support rod 220 moves to the bottom of the stacking rack 100 along with the rubber belt 150 and slides out due to gravity, so that the tire placing part 200 can continue to place tires for use when the entire tire placing part 200 is transferred to the front of the stacking rack 100. That is, the staff only needs to place the tires, which simplifies the tire stacking process and saves physical effort.

[0052] Furthermore, the top of the magnetic block 312 is rotatably connected to the bottom end of the guide rod magnetic plate 311 through a pin, so that the guide rod magnetic plate 311 can be folded and stored backward; the tire placement part 200 holds the tire and rotates to the rear side of the stacking rack 100 along with the rubber belt 150. When passing through the rod groove 113, the inner end of the supporting rod 220 is magnetically guided by the guide rod magnetic plate 311 and magnetically positioned by the magnetic block 312 and instantly retreats into the stacking rack 100, and then the tire falls directly to the ground. As the tires are unloaded by a number of tire placement parts 200, they are stacked into a pile.

[0053] Specifically, a plurality of clip strips 152 are transversely arranged on the outer side of the rubber belt 150, and a clip groove 211 which is sleeved with the clip strip 152 is provided on the inner wall of the support plate 210. The clip strip 152 is a round rod structure, and the cross section of the clip groove 211 is C-shaped, thereby forming a limiting structure, so that the support plate 210 and the rubber belt 150 fit together without slipping; a plurality of tooth-shaped grooves 151 are provided on the inner center line of the rubber belt 150, and the servo motor 160 is installed on the side wall of the stacking rack 100 and its output shaft extends into the side wall of each stacking rack 100, and a transmission gear 161 is sleeved on the output shaft of the servo motor 160 and located on the inner side of each rubber belt 150, and the transmission gear 161 is meshed with the tooth-shaped groove 151, so that the servo motor 160 stably drives the rubber belt 150 to drive the movement of the plurality of tire placing parts 200 to circulate and transport the tires.

[0054] Furthermore, adjusting holes 212 are provided at the four corners of the front side of the support plate 210, and threaded holes connected to the adjusting holes 212 are provided on the vertical side of the support plate 210. The outer wall of the adjusting rod 230 uses an external thread and is threadedly connected to the threaded hole, that is, the support rod 220 is driven to move by rotating the adjusting rod 230, and a limiting wheel 221 is embedded in the outer end of the support rod 220. The setting of the limiting wheel 221 allows smooth tire removal and placement; the outer diameter of the limiting wheel 221 is larger than the outer diameter of the support rod 220, so that when the support rod 220 retreats, it is blocked by the rod sleeve 231 and does not slip.

[0055] Furthermore, a vertical sleeve rod 313 is fixedly connected to the inner side surface of the magnetic block 312, and the telescopic tube 320 is composed of a plurality of sleeves 321 connected inside and outside, and a bolt is embedded in the outer wall of the top of each sleeve 321, and the bolt is rotated to pre-tighten the overall height of the telescopic tube 320; the sleeve rod 313 is sleeved and matched with the innermost sleeve 321 of the telescopic tube 320 for plugging and unplugging; the bottom of the telescopic tube 320 is fixedly connected to a ring 322, and a radial side of the ring 322 is fixedly connected to a telescopic rod 323, and the outer end of the telescopic rod 323 is fixedly connected to the inner wall of the stacking rack 100 by bolts, thereby supporting the magnetic suction component 310 to rise and work.

[0056] It is worth noting that the stacking rack 100 includes a pair of upright plates 110, a pair of bottom plates 120 rotatably connected between the bottoms of the pair of upright plates 110, an upper chain plate 130 rotatably connected between the tops of the pair of upright plates 110, and a lower chain plate 140 rotatably connected between the middle and lower parts of the pair of upright plates 110; a folding rack portion 400 for folding the stacking rack 100 up and down is provided in the middle part of the stacking rack 100, so that the stacking rack 100 can be folded to reduce the volume for storage;

[0057] The folding frame part 400 includes a pair of support rods 410 slidably connected to the outermost sides of a plurality of stacking frames 100, a plurality of take-up wheels 420 coaxially connected between the middle parts of the pair of support rods 410, tension springs 430 reversely hung at both ends of the support rods 410, and a drawstring 450 and a tensioning rod 440 reversely wound on the take-up wheels 420; the upper end of the drawstring 450 is hung with the upper chain plate 130, and the drawstring 450 is made of nylon belt, which has high tensile strength; the lower end of the tensioning rod 440 is hung with the lower chain plate 140, and the drawstring 440 is made of elastic tendons, which elastically pulls the lower chain plate 140; a plurality of take-up wheels 420 are connected to the pair of support rods 410 by plugging in a long axis, wherein the ring 322 is slidably sleeved with the long axis, so that the magnetic attraction member 310 is stably supported and does not turn with the rotation of the take-up wheel 420.

[0058] Specifically, the upper chain plate 130 is composed of an arch plate 131 and an articulated frame 132 hinged at both ends thereof, the pull belt 450 is hung and cooperated with a circular ring welded in the middle of the inner arc surface of the arch plate 131, and an arc groove 1321 is provided on the upper half side of the articulated frame 132; so that when the arch plate 131 is pulled down, it slides relative to the arc groove 1321 to avoid interference; the lower chain plate 140 is composed of a lower concave plate 141 and a sliding sleeve 142 hinged at both ends thereof, the tie rod 440 is hung and cooperated with a circular ring welded in the middle of the inner arc surface of the lower concave plate 141, the sliding sleeve 142 is an arc-shaped ring structure and a sleeve 1421 is provided on the upper end side thereof, the sleeve 1421 is sleeved and slid on the output shaft of the servo motor 160 to prevent the sleeve 1421 from rotating with its output shaft.

[0059] Furthermore, a slide groove 114 is provided in the middle of the outer side surface of the stacking frame 100 on the outside in an up-down reverse direction, and a rectangular parallelepiped slider 411 is sleeved at both ends of the support rod 410. The slider 411 is engaged and slides with the slide groove 114, so that when the support rod 410 slides to an inclined state, that is, a state where a pair of upright plates 110 are folded; a limiting groove 115 connected to the slide groove 114 is provided on the inner wall of the stacking frame 100 on the outside, and a slider 411 is embedded in the inner side of the slider 411. There is a pin that is slidably inserted into the limit groove 115 to prevent the support rod 410 from slipping; one end of the tension spring 430 is sleeved with the slider 411 toward the outside, and the other end of the tension spring 430 is fixedly connected to the side wall of the stacking rack 100. The tension spring 430 rebounds and the support rod 410 is rotated to a horizontal horizontal state to spread a pair of upright plates 110, thereby driving the upper chain plate 130 and the lower chain plate 140 to form arc ends, and spreading the rubber belt 150 to smoothly transport the tire placement part 200.

[0060] Furthermore, a through hole 111 is provided on the bottom side of the upright plate 110 so that the tire placement part 200 can rotate and pass through; an arc guide plate 112 is provided on the upper end of the through hole 111, and the outward side of the arc guide plate 112 is an arc surface, and the inner side of the arc guide plate 112 is a straight surface and is flush with the inner side of the upright plate 110; it is used to guide the rubber belt 150 to bend; the rod groove 113 provided on the rear side of the stacking rack 100 extends to the bottom end of the arc guide plate 112, so that when the support rod 220 retreated into the stacking rack 100 slides to the position of the arc guide plate 112 in the rod groove 113, the support rod 220 slides out downward because the friction between the support rod 220 and the rod sleeve 231 is less than the gravity of the support rod 220, and then is fully extended through the guidance of the outer arc surface of the lower concave plate 141;

[0061] The sum of the friction force between the tire and the four supporting rods 220 and the friction force between the supporting rods 220 and the rod sleeves 231 is greater than the deadweight of the supporting rods 220, so as to prevent the supporting rods 220 from slipping when passing through the gap of the articulated frame 132; the arc guide plate 112 and the lower chain plate 140 are arranged coaxially;

[0062] The outer side surface of the stacking rack 100 on the outside is provided with limit holes 116 at the top and bottom, the limit holes 116 are connected with the slide groove 114 and are connected with limit blocks, the lower limit block is used to clamp the support rod 410 to keep it horizontal, and the upper limit block is used to support the support rod 410 in an inclined state, keep a pair of upright plates 110 close together, so that the stacking rack 100 can be folded and stored stably; the front side surface of the stacking rack 100 is symmetrically provided with limit strips 117 clamped with the rubber belt 150, so as to limit the rubber belt 150 and maintain its stable conveying movement; the lower halves of several stacking racks 100 are welded or bolted with connecting plates 118 to enhance the overall strength. At the same time, the output shaft of the servo motor 160 passes through the side wall of the connecting plate 118 and is stably supported.

[0063] The present invention also provides a method for using the tire stacking robot for recycling waste tires. Using the tire stacking robot for recycling waste tires comprises the following steps:
