[0036] The guide plate mechanism 3 includes a plurality of evenly distributed first frames 31, the first frames 31 are fixedly mounted on the top of the workbench 1, the tops of the first frames 31 are rotatably mounted with first rollers 32, the outer movable sleeves of the plurality of first rollers 32 are provided with first belts 33, a plurality of pallet bodies 7 are placed on the upper surface of the first belts 33, a third motor 34 is fixedly mounted on the top of one of the first frames 31, the driving end of the third motor 34 and the end of the corresponding first roller 32 are fixedly mounted, when in use, the cleaned pallet body 7 is placed on the upper surface of the first belt 33, the third motor 34 is controlled to start to drive the first roller 32 to rotate, thereby controlling the first belt 33 to transmit, and then driving the plurality of pallet bodies 7 to be transmitted, and the pallet bodies 7 are transmitted to one end of the transfer mechanism 2 in sequence.

[0037] The material transfer mechanism 2 includes two symmetrically distributed material transfer vertical frames 21, which are fixedly connected to one side of the top of the workbench 1. A material transfer shaft 22 is rotatably installed on the top of the two material transfer vertical frames 21. Material transfer frames 23 are fixedly installed on both ends of the material transfer vertical frames 21. Rotating shafts 24 are rotatably installed on both ends of the material transfer frames 23. Positioning frames 241 are fixedly installed on the opposite ends of the rotating shaft 24. A positioning slide shaft 242 is slidably inserted on the side of the positioning frame 241 away from the rotating shaft 24. A connecting frame 243 is fixedly installed on the end of the positioning slide shaft 242 close to the rotating shaft 24. An L-shaped positioning The telescopic rod 245 is fixedly mounted on the side of the positioning frame 241 close to the rotating shaft 24, and the driving end of the telescopic rod 245 is fixedly mounted on the connecting frame 243. When in use, the telescopic rod 245 on the same side is controlled to open, and the corresponding connecting frame 243, the positioning slide shaft 242 and the L-shaped positioning frame 244 are driven to move toward each other, and the tray body 7 can be positioned by the L-shaped positioning frames 244 on both sides.

[0038] The two ends of the transfer shaft 22 are fixedly installed with the first worm gear 25, the bottom of the first worm gear 25 is meshingly connected with the first worm 251, and the first motor 252 is fixedly installed on the side of the transfer vertical frame 21 close to the first worm 251, and the driving end of the first motor 252 and one end of the first worm 251 are fixedly installed. When in use, the first motor 252 is controlled to start driving the first worm 251 to drive the first worm gear 25, the transfer shaft 22 and the transfer frame 23 to rotate, thereby driving the two sets of positioning frames 241 on both sides and the corresponding L-shaped positioning frames 244 to change their positions.

[0039] The two ends of the transfer shaft 22 are movably sleeved with a first sprocket 26 and a second sprocket 261, and the first sprocket 26 and the second sprocket 261 are fixedly mounted on the bottom of the transfer vertical frame 21, and the ends of the rotating shaft 24 at the two end positions of the transfer frame 23 are respectively fixedly mounted on the third sprocket 262 corresponding to the first sprocket 26 and the second sprocket 261, and the first sprocket 26 and the second sprocket 261 are respectively meshed and connected with the outer sides of the corresponding third sprocket 262 with a limiting chain 263. When the two groups of positioning frames 241 on both sides and the corresponding L-shaped positioning frames 244 are converted, since the first sprocket 26 and the second sprocket 261 are fixed, the limiting transmission effect of the limiting chain 263 drives the third sprocket 262 and the rotating shaft 24 to rotate on the corresponding transfer frame 23, and the two groups of positioning frames 241 on both sides are always kept in a horizontal state, so that the tray body 7 is always kept in a horizontal state, thereby improving the stability of the position conversion of the tray body 7.

[0040] The stacking assembly 4 includes two groups of symmetrically distributed longitudinal clamping frames 41, which are fixedly mounted on the top of the workbench 1 on one side away from the guide plate mechanism 3. The two groups of longitudinal clamping frames 41 are both slidably clamped with longitudinal sliding racks 42 on the opposite sides. The longitudinal sliding racks 42 can slide vertically on the corresponding longitudinal clamping frames 41. The top opposite sides of the longitudinal sliding racks 42 are both fixedly mounted with drag rods 43. The pallet body 7 is transferred from the position of the material transfer mechanism 2 to the stacking assembly 4 and placed on the drag rods 43. Then, the pallet body 7 loses its position and is placed on multiple drag rods 43 for subsequent stacking.

[0041] The bottom of the longitudinal sliding rack 42 slides and extends to the bottom end of the workbench 1. The bottoms of the two sets of longitudinal sliding racks 42 are meshed and connected with driving gears 44 on opposite sides. A first shaft 441 is fixedly installed in the middle of the two driving gears 44 on the same side. The first shaft 441 is rotatably installed at the bottom end of the workbench 1. Second worm gears 45 are fixedly installed at both ends of the first shaft 441. The two first shafts 441 are symmetrically distributed with the second worm gears 45 at the end positions. The bottom of the second worm gear 45 is meshed and connected with a second worm 451. The two first shafts 441 are symmetrically distributed with the second worm gears 45 at the end positions. A second shaft 452 is fixedly installed between the first shaft 441 and the second worm 451 at the end position. The second shaft 452 is rotatably installed at the bottom end of the workbench 1. A first gear 46 is fixedly installed at one end of the second shaft 452. A first crown gear 461 is meshed and connected to one side of the first gear 46. A third shaft 462 is fixedly installed in the middle of the two first crown gears 461. The third shaft 462 is rotatably installed at the bottom of the material transfer vertical frame 21. One-way bearings 47 are fixedly installed at both ends of the third shaft 462. The outer fixed sleeve of the bearing 47 is provided with a fourth sprocket 471, and the two ends of the transfer shaft 22 are fixedly installed with fifth sprockets 472. The outer sides of the fourth sprocket 471 and the fifth sprocket 472 are vertically meshed and connected with a transmission chain 473. The transfer longitudinal frame 21 rotates to drive the two sets of positioning frames 241 on both sides to transfer, and cooperates with the transmission of the fourth sprocket 471, the fifth sprocket 472 and the transmission chain 473 to drive the outer ring of the one-way bearing 47 to rotate. At this time, the inner and outer rings of the one-way bearing 47 are self-locking, thereby driving The inner ring of the one-way bearing 47 and the third shaft 462 rotate, thereby driving the first crown gear 461 to drive the first gear 46 and the second shaft 452 to rotate, thereby driving the second worm gear 45 to rotate through the second worm 451, and then driving the first shaft 441 and the driving gear 44 to rotate slowly, thereby controlling the longitudinal sliding rack 42 and multiple drag rods 43 to synchronously descend a short distance, and the pallet body 7 placed on the multiple drag rods 43 descends, so that the next pallet body 7 can be placed on the pallet body 7 for stacking.

[0042] A reset motor 48 is fixedly installed on one side of the bottom end of the workbench 1 near the third shaft 462, and the driving end of the reset motor 48 is fixedly installed on one end corresponding to the third shaft 462. When the longitudinal sliding rack 42 and multiple drag rods 43 drop to the bottom position and multiple tray bodies 7 are stacked, it is necessary to reset the longitudinal sliding rack 42 and multiple drag rods 43. At this time, it is only necessary to control the reset motor 48 to start the third shaft 462 for reverse rotation. The inner and outer rings of the one-way bearing 47 are not self-locking and will not drive the fourth sprocket 471 to rotate. The third shaft 462 rotates in the reverse direction, driving the first crown gear 461 to drive the first gear 46 and the second shaft 452 to rotate in the reverse direction, thereby driving the second worm gear 45 to rotate in the reverse direction through the second worm gear 451, and then driving the first shaft 441 and the driving gear 44 to rotate in the reverse direction, thereby controlling the longitudinal sliding rack 42 and multiple drag rods 43 to move up and reset.

[0043] The limiting member 6 includes two symmetrically distributed first limiting frames 61, the first limiting frames 61 are respectively fixedly installed on the top of the workbench 1 corresponding to each group of longitudinal clamping frames 41, a second limiting frame 62 is provided between the two first limiting frames 61, the second limiting frame 62 is fixedly installed on the top of the workbench 1, a limiting cross frame 63 is provided on the side of the first limiting frame 61 away from the second limiting frame 62, longitudinal side frames 64 are fixedly installed on both sides of the bottom end of the limiting cross frame 63, and the longitudinal side frames 64 are fixedly installed on the top of the workbench 1. By setting two first limiting frames 61, the second limiting frame 62 and the limiting cross frame 63, the stacked and descending pallet body 7 is limited to prevent the stacked pallet body 7 from displacement and improve the stability of the stacking of the pallet body 7.

[0044] The tray discharging mechanism 5 includes a plurality of evenly distributed second frames 51, which are fixedly mounted on one side of the top of the workbench 1 close to the stacking assembly 4. Second rollers 52 are rotatably mounted on the top of the second frames 51, and second belts 53 are movably sleeved on the outer sides of the plurality of second rollers 52. A fourth motor 54 is fixedly mounted on the top of one of the second frames 51, and a driving end of the fourth motor 54 and an end portion of the corresponding second roller 52 are fixedly mounted. When the longitudinal sliding rack 42 and the plurality of drag rods 43 are lowered to the bottommost position, the plurality of pallet bodies 7 are stacked. At the same time, the plurality of pallet bodies 7 after stacking are placed on the second belt 53, and the longitudinal sliding rack 42 and the plurality of drag rods 43 continue to be lowered. The second belt 53 supports the plurality of pallet bodies 7, and the pallet bodies 7 at the bottommost position are separated from the plurality of drag rods 43. Subsequently, the fourth motor 54 is controlled to be turned on to drive the corresponding second rollers 52 to rotate, thereby driving the second belt 53 to transmit, and then controlling the plurality of pallet bodies 7 after stacking to move out of the stacking assembly 4, and automatically discharging the pallet bodies 7.

[0045] Working principle: When in use, the cleaned tray body 7 is placed on the upper surface of the first belt 33, and the third motor 34 is controlled to start to drive the first roller 32 to rotate, thereby controlling the first belt 33 to transmit, and then driving multiple tray bodies 7 to be transmitted, and the tray bodies 7 are sequentially transmitted to one end of the transfer mechanism 2;

[0046] At the same time, the first motor 252 is controlled to start driving the first worm 251 to drive the first worm wheel 25, the material transfer shaft 22 and the material transfer frame 23 to rotate, thereby driving the two groups of positioning frames 241 on both sides and the corresponding L-shaped positioning frames 244 to switch positions. When one group of positioning frames 241 and L-shaped positioning frames 244 moves to the position of the guide plate mechanism 3, the telescopic rod 245 at the position of this group is controlled to start, and the corresponding connecting frame 243, the positioning slide shaft 242 and the L-shaped positioning frame 244 are driven to move toward each other, and the tray body 7 can be positioned through the L-shaped positioning frames 244 on both sides;

[0047] After positioning is completed, the tray body 7 is continuously rotated. Since the first sprocket 26 and the second sprocket 261 are fixed, the limiting transmission function of the limiting chain 263 is cooperated to drive the third sprocket 262 and the rotating shaft 24 to rotate on the corresponding material transfer rack 23, and the two sets of positioning frames 241 on both sides are always kept in a horizontal state, so that the tray body 7 is always kept in a horizontal state;

[0048] The pallet body 7 is transferred from the material transfer mechanism 2 to the stacking assembly 4 and placed on the drag rod 43, and then the pallet body 7 is made to lose its position, and the pallet body 7 is placed on a plurality of drag rods 43 for subsequent stacking;

[0049] The material transfer longitudinal frame 21 rotates to drive the two sets of positioning frames 241 on both sides to transfer, and cooperates with the transmission of the fourth sprocket 471, the fifth sprocket 472 and the transmission chain 473 to drive the outer ring of the one-way bearing 47 to rotate. At this time, the inner and outer rings of the one-way bearing 47 are self-locking, thereby driving the inner ring of the one-way bearing 47 and the third shaft 462 to rotate, thereby driving the first crown gear 461 to drive the first gear 46 and the second shaft 452 to rotate, thereby driving the second worm gear 45 to rotate through the second worm 451, thereby driving the first shaft 441 and the driving gear 44 to rotate slowly, thereby controlling the longitudinal sliding rack 42 and multiple drag rods 43 to synchronously descend a short distance, and the pallet body 7 placed on the multiple drag rods 43 descends, so that the next pallet body 7 is placed on the pallet body 7 for stacking;

[0050] The stacked and descending pallet bodies 7 are limited by setting two first limiting frames 61, a second limiting frame 62 and a limiting horizontal frame 63 to prevent the stacked pallet bodies 7 from shifting;

[0051] Until the stacking of the plurality of pallet bodies 7 is completed, the longitudinal sliding rack 42 and the plurality of drag rods 43 are lowered to the bottom position, and the longitudinal sliding rack 42 and the plurality of drag rods 43 are further lowered, the second belt 53 supports the plurality of pallet bodies 7, and the pallet bodies 7 at the bottom position are separated from the plurality of drag rods 43, and then the fourth motor 54 is controlled to start driving the corresponding second roller 52 to rotate, thereby driving the second belt 53 to transmit, and then controlling the plurality of pallet bodies 7 that have been stacked to move out of the stacking assembly 4, and the pallet bodies 7 are automatically discharged;

[0052] Subsequently, the longitudinal sliding rack 42 and the multiple drag rods 43 are reset. At this time, it is only necessary to control the reset motor 48 to start the third shaft 462 for reverse rotation. The inner and outer rings of the one-way bearing 47 are not self-locking and will not drive the fourth sprocket 471 to rotate. The third shaft 462 rotates in the reverse direction, driving the first crown gear 461 to drive the first gear 46 and the second shaft 452 to rotate in the reverse direction, thereby driving the second worm gear 451 to drive the second worm gear 45 to rotate in the reverse direction, and then driving the first shaft 441 and the driving gear 44 to rotate in the reverse direction, thereby controlling the longitudinal sliding rack 42 and the multiple drag rods 43 to move up and reset.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
