Description

Technical Field

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

[0002] After the packaging boxes are produced, they will be stacked on top of plastic pallets and moved to designated locations using the plastic pallets for easy storage. When the packaging boxes need to be rented out, the plastic pallets will also be used to move the packaging boxes to the transport vehicles. Therefore, a large number of plastic pallets will be needed during the production and subsequent rental process of the packaging boxes.

[0003] When the plastic pallets need to be recycled later, they need to be crushed to facilitate the subsequent processing of the crushed debris. In the existing technology, when crushing plastic pallets, the plastic pallets to be crushed are usually placed in a large crushing roller, and the crushing roller is used to crush the plastic pallets into debris. However, since some plastic pallets have steel pipes placed in the bottom feet to increase the support force of the plastic pallets and reduce the deformation of the plastic pallets, when the crushing roller is directly used to crush the plastic pallets with built-in steel pipes, the excessive hardness of the steel pipes can easily damage the surface of the crushing roller, affecting the crushing effect of the crushing roller. Therefore, before crushing the plastic pallets with built-in steel pipes, the steel pipes need to be taken out. At this time, the staff needs to use a handheld crusher to crush the plastic at the bottom feet of the plastic pallet until the internal steel pipes are exposed. After the steel pipes are taken out, the plastic pallets are placed in the crushing roller to be crushed. The steps are complicated, which greatly reduces the crushing efficiency and reliability of the plastic pallets.

After the steel pipe is taken out, 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 now described as follows:

[0037] In the present invention, when the plastic pallet needs to be recycled and crushed, the two second electric slide rails 8 are first controlled to start, driving the corresponding three second slide plates 9 to move, thereby driving the second electric telescopic rod 101 to move, so that the spacing between the corresponding three fixed crushing cylinders 104 is the same as the spacing between the bottom feet on both sides of the plastic pallet, and then the third electric telescopic rod 103 and the second electric telescopic rod 101 are controlled to start, driving the corresponding fixed crushing cylinder 104 to move, so that the distance and arrangement between the multiple fixed crushing cylinders 104 can match the position of the corresponding plastic pallet bottom feet, and then the staff will put the plastic pallet to be crushed into the crushing box 1, and put the bottom feet of the plastic pallet into the corresponding fixed crushing cylinder 104, and then control the multiple second motors 1 020 is started, driving the corresponding round rod 1019 to rotate. During the rotation of the round rod 1019, the sixth electric telescopic rod 1021 and the splint 1022 are driven to rotate. When the inclination angle of the splint 1022 matches the inclination angle of the corresponding plastic pallet bottom foot side wall, the second motor 1020 is controlled to be closed, and then the sixth electric telescopic rod 1021 is controlled to start, driving the splint 1022 to move toward the side wall of the plastic pallet bottom foot, and the splint 1022 is used to fix the plastic pallet bottom foot, so that the plastic pallet can be crushed by the first crusher 68 later. Then, the first electric slide rail 3 is controlled to start, driving the corresponding first slide plate 4 to move, so that the mounting frame 5 moves to the top of the crushing box 1, and then the third electric slide rail 62 and the fourth electric slide are controlled to start. The rail 65 is started, driving the corresponding third slide 63 and the fourth slide 66 to move, so that the first crusher 68 can move to various areas of the plastic pallet, and the first electric telescopic rod 67 and the first crusher 68 are controlled to start, so that the first crusher 68 crushes the plastic pallet, and the first crusher 68 avoids the bottom part of the plastic pallet during the crushing process of the plastic pallet, and only crushes the other parts of the plastic pallet. When most of the plastic pallet is crushed and only the bottom part of the plastic pallet is left, the first electric slide rail 3 and the first electric telescopic rod 67 are controlled to return to their original positions, and then the fourth electric telescopic rod 109 above the multiple fixed crushing cylinders 104 is controlled to start, driving the first side plate 1010 to move upward, so that the second crusher 1017 is located at the plastic pallet. The plastic pallet bottom foot is then controlled to move upward, and the control unit 1022 is controlled to return to its original position above the fixed crushing cylinder 104, without fixing the plastic pallet bottom foot. The control unit 108 is then controlled to start the first motor 108, driving 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 cylinder 104. The control unit 1016 is then controlled to start the fifth electric telescopic rod 1016, driving the second crusher 1017 to move downward, and using the second crusher 1017 to crush the plastic pallet bottom foot. In this process, the control unit 106, the sixth electric slide rail 1011 and the seventh electric slide rail 1014 are controlled to start, driving the corresponding fifth slide plate 107, the sixth slide plate 1012 and the seventh slide plate 1015 to move.The second crusher 1017 is enabled to crush the upper half of the plastic pallet foot, and when the second crusher 1017 is used to crush the corresponding upper half of the plastic pallet foot, the movement of the sixth slide 1012 and the seventh slide 1015 is controlled to make the second crusher 1017 avoid the position of the steel pipe inside the plastic pallet foot, so that the second crusher 1017 crushes the part outside the steel pipe inside the plastic pallet foot, so that the upper half of the steel pipe is exposed. After the upper half of the plastic pallet foot is crushed and the upper half of the steel pipe is exposed, the fixed The seventh electric telescopic rod 1023 above the crushing cylinder 104 is started, driving the clamping ring 1024 to move, and the clamping ring 1024 is used to fix the upper half of the steel pipe. Then, the clamping plate 1022 in a group below the fixed crushing cylinder 104 is controlled to return to its original position. Then, the second crusher 1017 below the fixed crushing cylinder 104 is controlled to crush the lower half of the plastic pallet foot, so that the steel pipe inside the plastic pallet foot is completely exposed. At this time, the crushing of the plastic pallet foot is completed, and the steel pipe inside the plastic pallet foot is extracted. At the same time, the crushed debris of the plastic pallet is evenly distributed. The plastic pallet is located at the bottom of the crushing box 1, which is convenient for subsequent collection so that the debris can be processed later. The steel pipe fixed by the clamping ring 1024 in the fixed crushing cylinder 104 can be directly taken away by the staff. When the plastic pallet needs to be crushed, the position of the fixed crushing cylinder 104 can be changed according to the position of the plastic pallet foot, so that the plastic pallet foot is placed in the corresponding fixed crushing cylinder 104, and 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 foot, so that the plastic pallet foot can be fixed by the clamping plate 1022. The first crusher 68 can crush all parts of the plastic pallet except the base. The second crusher 1017 can also crush the base of the plastic pallet. When crushing the base of the plastic pallet, the steel pipe inside the base of the plastic pallet is avoided and the steel pipe is extracted separately, eliminating the need for workers to hold the crusher to crush the plastic at the base of the plastic pallet until the steel pipe inside is exposed. After the steel pipe is removed, the plastic pallet is put into the crushing roller to crush it. This greatly improves the crushing efficiency and reliability of the device when crushing plastic pallets.
