Description

Technical Field

[0001] The invention belongs to the technical field of pallet crushing, and particularly relates to a recycling and crushing device for plastic pallets used for packing boxes. Background Art

[0002] After the packing boxes are produced, the packing boxes will be stacked above the plastic pallets, and the plastic pallets are used to move the packing boxes to the designated positions to facilitate the storage of the packing boxes. And when the packing boxes need to be leased outwards, the plastic pallets are also used to move the packing boxes into the transport vehicles. Therefore, a large number of plastic pallets are needed during the production and later leasing processes of the packing boxes.

[0003] When the plastic pallets need to be recycled subsequently, the plastic pallets need to be crushed to facilitate the subsequent processing of the crushed debris. In the prior art, when crushing the plastic pallets, the plastic pallets to be crushed are usually put into a large crushing roller, and the crushing roller is used to crush the plastic pallets into debris. However, since some steel pipes are placed inside the bottom feet of the plastic pallets to improve the supporting force of the plastic pallets and reduce the deformation of the plastic pallets, when directly using the crushing roller to crush the plastic pallets with steel pipes inside, the too high hardness of the steel pipes is likely to cause damage to the surface of the crushing roller and affect the crushing effect of the crushing roller. Therefore, before crushing the plastic pallets with steel pipes inside, the steel pipes need to be taken out. At this time, the staff also needs to hold a crusher to crush the plastic at the bottom feet of the plastic pallets until the internal steel pipes are exposed. After the steel pipes are taken away, the plastic pallets are put into the crushing roller for crushing. The steps are complex, which greatly reduces the crushing efficiency and reliability when crushing the plastic pallets.

[0004] Therefore, we propose a recycling and crushing device for plastic pallets used for packing boxes to solve the above problems. Summary of the Invention

During the crushing process of the plastic tray by the first crusher 68, the bottom feet part of the plastic tray is avoided, and only other parts of the plastic tray are crushed. When most of the plastic tray is crushed and only the bottom feet part of the plastic tray remains, the first electric slide rail 3 and the first electric telescopic rod 67 are controlled to return to their original positions.

[0030] In the embodiment, the tray bottom foot steel pipe fixed extraction assembly 10 includes a second electric telescopic rod 101 fixedly connected to the side wall of one end of the second slide plate 9. Two fourth grooves 102 are symmetrically formed in the inner walls of both ends of the crushing box 1. The inner walls of the fourth grooves 102 are fixedly connected with third electric telescopic rods 103. The telescopic ends of the third electric telescopic rods 103 and the second electric telescopic rod 101 are both fixedly connected with fixed crushing cylinders 104;

The bottom side wall of the seventh slide plate 1015 is fixedly connected with a fifth electric telescopic rod 1016. The telescopic end of the fifth electric telescopic rod 1016 is fixedly connected with a second crusher 1017;

[0033] Two groups of U-shaped plates 1018 are symmetrically and fixedly connected to the inner walls of multiple fixed crushing cylinders 104. Each group of U-shaped plates 1018 has two. A round rod 1019 is rotatably connected to the inner wall of the U-shaped plate 1018. One end side wall of the U-shaped plate 1018 is fixedly connected with a second motor 1020.

Each group of seventh electric telescopic rods 1023 has two. The telescopic ends of the seventh electric telescopic rods 1023 are all fixedly connected with clamping rings 1024.

[0035] Specifically, when it is necessary to crush the plastic pallet, the position of the fixed crushing cylinder 104 can be changed according to the position of the bottom feet of the plastic pallet, so that the bottom feet of the plastic pallet are placed into the corresponding fixed crushing cylinder 104. Then, the inclination angle of the clamping plate 1022 is adjusted according to the inclination angle of the side wall of the corresponding plastic pallet bottom foot, which is convenient for fixing the plastic pallet bottom foot by using the clamping plate 1022, so that the first crusher 68 can crush other parts of the plastic pallet except the bottom feet. The second crusher 1017 can also be used to crush the bottom feet of the plastic pallet. When crushing the bottom feet of the plastic pallet, the steel pipe inside the bottom feet of the plastic pallet is avoided, and the steel pipe is extracted separately, so as to avoid that the staff still needs to hold the crusher to crush the plastic at the bottom feet of the plastic pallet until the steel pipe inside is exposed. After the steel pipe is taken away, it is put into the crushing roller to crush the plastic pallet, which greatly improves the crushing efficiency and reliability of the device when crushing the plastic pallet.

[0036] The operating principle of the present invention is described as follows:

[0037] In the present invention, when it is necessary to recycle and crush a plastic pallet, first, control the two second electric slide rails 8 to start, drive the corresponding three second slide plates 9 to move, thereby driving the second electric telescopic rod 101 to move, so that the distance between the corresponding three fixed crushing cylinders 104 is the same as the distance between the bottom feet on both sides of the plastic pallet. Then, control the third electric telescopic rod 103 and the second electric telescopic rod 101 to start, drive the corresponding fixed crushing cylinders 104 to move, so that the distance and arrangement between the multiple fixed crushing cylinders 104 can match the positions of the bottom feet of the corresponding plastic pallet. Then, the staff puts the plastic pallet to be crushed into the crushing box 1, and makes the bottom feet of the plastic pallet enter the corresponding fixed crushing cylinders 104. Then, control the multiple second motors 1020 to start, drive the corresponding round rods 1019 to rotate. During the rotation of the round rods 1019, the sixth electric telescopic rod 1021 and the clamping plate 1022 will be driven to rotate. When the inclination angle of the clamping plate 1022 matches the inclination angle of the side wall of the bottom foot of the corresponding plastic pallet, control the second motor 1020 to stop. Then, control the sixth electric telescopic rod 1021 to start, drive the clamping plate 1022 to move towards the side wall of the bottom foot of the plastic pallet, and use the clamping plate 1022 to fix the bottom foot of the plastic pallet, which is convenient for subsequent crushing of the plastic pallet by the first crusher 68. Then, control the first electric slide rail 3 to start, drive the corresponding first slide plate 4 to move, so that the installation frame 5 moves to directly above the crushing box 1. Then, by controlling the third electric slide rail 62 and the fourth electric slide rail 65 to start, drive the corresponding third slide plate 63 and fourth slide plate 66 to move, so that the first crusher 68 can move in each area of the plastic pallet. By controlling the first electric telescopic rod 67 and the first crusher 68 to start, the first crusher 68 crushes the plastic pallet. During the crushing of the plastic pallet by the first crusher 68, the bottom foot part of the plastic pallet is avoided, and only other parts of the plastic pallet are crushed. When most of the plastic pallet is crushed and only the bottom foot part of the plastic pallet remains, control the first electric slide rail 3 and the first electric telescopic rod 67 to return to their original positions. Then, control the fourth electric telescopic rod 109 above the multiple fixed crushing cylinders 104 to start, drive the first side plate 1010 to move upward, so that the second crusher 1017 is located above the bottom foot part of the plastic pallet. Then, control the group of clamping plates 1022 above the fixed crushing cylinders 104 to return to their original positions and do not fix the bottom feet of the plastic pallet. Then, control the first motor 108 to start, drive the fourth electric telescopic rod 109 to rotate 180 degrees and then stop. At this time, the second crusher 1017 is located above the fixed crushing cylinders 104. Then, control the fifth electric telescopic rod 1016 to start, drive the second crusher 1017 to move downward, and use the second crusher 1017 to crush the bottom foot part of the plastic pallet. During this process, by controlling the fifth electric slide rail 106, the sixth electric slide rail 1011 and the seventh electric slide rail 1014 to start, drive the corresponding fifth slide plate 107, sixth slide plate 1012 and seventh slide plate 1015 to move,Enable the second shredder 1017 to shred the upper part of the plastic pallet foot. When using the second shredder 1017 to shred the corresponding upper part of the plastic pallet foot, by controlling the movement of the sixth slide plate 1012 and the seventh slide plate 1015, the second shredder 1017 is made to avoid the position of the steel pipe inside the plastic pallet foot, and the second shredder 1017 shreds the part outside the steel pipe inside the plastic pallet foot, leaving the upper part of the steel pipe exposed. After the upper part of the plastic pallet foot is broken and the upper part of the steel pipe is exposed, control the seventh electric telescopic rod 1023 above the fixed shredding cylinder 104 to start, drive the clamping ring 1024 to move, and use the clamping ring 1024 to fix the upper part of the steel pipe. Then control the clamping plate 1022 in the lower group of the fixed shredding cylinder 104 to return to its original position. Then control the second shredder 1017 below the fixed shredding cylinder 104 to shred the lower part of the plastic pallet foot, so that all the steel pipes inside the plastic pallet foot are exposed. At this time, the shredding of the plastic pallet foot is completed, and the steel pipes inside the plastic pallet foot are extracted. At the same time, the shredded debris of the plastic pallet is all located at the bottom of the shredding box 1, which is convenient for subsequent collection for subsequent processing of the debris. The steel pipe fixed by the clamping ring 1024 inside the fixed shredding cylinder 104 can be directly taken away by the staff. When it is necessary to shred the plastic pallet, the position of the fixed shredding cylinder 104 can be changed according to the position of the plastic pallet foot, so that the plastic pallet foot is placed into the corresponding fixed shredding cylinder 104. Then, according to the inclination angle of the side wall of the corresponding plastic pallet foot, the inclination angle of the clamping plate 1022 is adjusted to facilitate the fixation of the plastic pallet foot by the clamping plate 1022. The first shredder 68 can shred other parts of the plastic pallet except the feet, and the second shredder 1017 can also shred the plastic pallet feet. When shredding the plastic pallet feet, the steel pipes inside the plastic pallet feet are avoided, and the steel pipes are extracted separately, preventing the staff from having to hold the shredder to shred the plastic at the plastic pallet feet until the internal steel pipes are exposed. After the steel pipes are taken away, they are put into the shredding roller to shred the plastic pallet, greatly improving the shredding efficiency and reliability of the device when shredding the plastic pallet.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
