Detailed Implementation

[0017] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0018] like Figure 1 , Figure 2 As shown: A pallet recycling device includes a frame 1 and a pallet receiving rack 2; the pallet receiving rack 2 is located inside the frame 1; Material conveying mechanisms 3 are arranged on both sides of the pallet receiving rack 2 on the frame 1. A pallet lifting mechanism 4 is provided below the pallet receiving rack 2. A pallet stacking guide groove and a support claw 5 that can enter and exit within the range of the pallet stacking guide groove are provided above the pallet receiving rack 2. The support claw 5 can extend into the groove at the bottom of the pallet to receive the pallet. The pallet receiving rack 2 is installed at the working end of the pallet lifting mechanism 4.

[0019] like Figure 6 As shown: The pallet recycling device is located at the end of the roller conveyor line 16. The material conveying mechanism 3 is connected to the roller conveyor line 16, and the pallets output from the roller conveyor line 16 enter the material conveying mechanism 3.

[0020] A vertical limiting rod 7 is fixed on the frame 1. The vertical limiting rod 7 forms a pallet stacking guide groove, and one side of the pallet stacking guide groove is open for removing the pallet. The two ends of the vertical limiting rod 7 are bent outwards from the pallet stacking guide groove to prevent the pallet from being obstructed by collision when it is sent into the pallet stacking guide groove.

[0021] like Figure 3 As shown: The support claw 5 includes a support arm 5.1 and a prying arm 5.2. The hinge hole between the support arm 5.1 and the prying arm 5.2 connects to the frame 1. Two support claws 5 form a group, with one group arranged on each side of the pallet stacking guide groove. A rotary actuator 8 is installed between the two support claws 5 in the same group. A lever 10 is hinged between the swing block 9, which is driven to rotate by the rotary actuator 8, and the prying arm 5.2. The rotary actuator 8 is a pneumatic motor. When the rotary actuator 8 drives the swing block 9 to rotate, it pulls the support claw 5 to swing through the lever 10. The support arm 5.1 of the support claw 5 extends into or retracts from the pallet stacking guide groove.

[0022] like Figure 5As shown: The pallet lifting mechanism 4 includes guide posts 4.1 located at the four corners of the pallet receiving rack 2 and a lifting cylinder 4.2 located in the middle of the pallet receiving rack 2. The guide posts 4.1 are slidably engaged with the guide sleeves 4.3 on the frame 1. The piston rod of the lifting cylinder 4.2 is connected to the pallet receiving rack 2, and the cylinder body of the lifting cylinder 4.2 is fixedly connected to the frame 1. The guide posts 4.1 serve as lifting guides to make the pallet receiving rack 2 move vertically, and the lifting cylinder 4.2 provides driving force.

[0023] The pallet recycling device has three movement stages. In the first stage, the pallet receiving rack 2 is located at a low position, below the pallet 15 received by the receiving conveyor mechanism 3. In the second stage, the pallet lifting mechanism 4 pushes the pallet receiving rack 2 upward, lifting the pallet 15 on the receiving conveyor mechanism 3 and continuing to move upward. At this time, the support claw 5 retracts outside the pallet stacking guide groove, and the pallet receiving rack 2 sends the pallet 15 into the pallet stacking guide groove. Then, the support claw 5 returns to the pallet stacking guide groove to catch the pallet 15, and the pallet receiving rack 2 resets and returns to the first stage. In the third stage... In the first stage, pallets 15 have already been stacked in the pallet stacking guide groove. The pallet receiving rack 2 lifts up the new pallet 15, which in turn lifts the already stacked pallets 15 in the pallet stacking guide groove, completing the force transfer from the support claw 5 to the pallet receiving rack 2. The pallet receiving rack 2 then pushes the pallet 15 upwards as a whole, allowing the support claw 5 to extend into the groove of the bottom pallet 15, completing the force transfer from the pallet receiving rack 2 to the support claw 5. The pallet receiving rack 2 then resets and returns to the first stage. The third stage and the first stage cycle repeat, completing the recycling and stacking of pallets 15.

[0024] The material conveying mechanism 3 is a chain conveying mechanism. The material conveying mechanisms 3 on both sides are driven coaxially, so that the pallets move synchronously on both sides.

[0025] like Figure 4 As shown: The distance between the two material conveying mechanisms 3 can be adjusted to adapt to the bottom structure of the pallet. The material conveying mechanism 3 slides with the slide rail 12 on the frame 1 through the linear sliding seat 11. The slide rail 12 has positioning holes 12.1 distributed at intervals. The linear sliding seat 11 is locked on the slide rail 12 by the pins inserted into the positioning holes 12.1. The drive gear 3.1 of the material conveying mechanism 3 and the drive shaft 13 have a polygonal hole and a polygonal prism sliding fit structure, so that the drive gear 3.1 slides on the drive shaft 13 while maintaining torque transmission.

[0026] A guide plate 14 is provided above the material conveying mechanism 3 to further prevent the pallets on the material conveying mechanism 3 from tilting.

[0027] A proximity switch 6 is installed on the top of the pallet stacking guide on the frame 1. When the pallet stacking guide is full of pallets, the proximity switch 6 sends a signal, and the pallet recycling device stops receiving new pallets.

[0028] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
