Description

Technical Field

[0001] The invention relates to the technical field of plastic particle stacking, in particular to an automatic stacking device for recycled plastic particles. Background Art

[0002] With the rapid development of industrial automation technology, the logistics industry has an increasing demand for automation of packaging and palletizing processes. In the production and processing of recycled plastic particles, the production process of recycled plastic particles usually includes multiple links such as recycling, cleaning, crushing, melting, extrusion and cutting. The final particles need to be packaged for storage and transportation. The packaged particles are usually stacked on pallets or other carriers for easy transportation and storage.

[0003] After searching, the Chinese patent with the announcement number CN220282861U provides a bagged polyurethane granule stacking device, which limits the material by setting a baffle and ensures that the position of the material is kept accurate. The hook gradually separates from the contact support of the material, so that one side of the material first descends and contacts the material below, and then slowly falls on the material below. By setting a lifting and lowering pressure plate, the top surface of the material can be flattened after stacking, which is convenient for stacking and stacking of subsequent materials.

[0004] However, it was found during use that the device is usually only used for palletizing single or uniform-sized bagged particles. When palletizing multiple bagged particles or bagged particles of different sizes, the device is difficult to use and even requires frequent adjustment or replacement of clamps to accommodate materials of different sizes, thereby reducing the efficiency and flexibility of automated palletizing.

[0025] 3.

[0043] Working principle: First, the device is installed on the external palletizing robot arm through the connecting seat 3. When the bagged recycled plastic particles after packaging are palletized, the clamping block 901 is adjusted to a suitable position through the adjusting component 9. The rotating shaft 5 drives the claws 6 to rotate synchronously for clamping, so that the claws 6 on one side of the frame 1 rotate, and the connecting rod 7 drives the claws 6 on the other side of the frame 1 to rotate synchronously. The claws 6 at both ends of the frame 1 rotate in opposite directions, so that the claws 6 at both ends clamp the bagged recycled plastic particles. During the clamping process, the position of the clamping block 901 is adjusted to adapt to the clamping of bagged recycled plastic particles of different sizes. The bagged recycled plastic particles after clamping move synchronously with the movement of the robot arm, and the bagged recycled plastic particles are moved to a suitable pallet or carrier for palletizing.

[0044] At the same time, with the adaptive adjustment of the clamp block 901, it is convenient to stack and clamp multiple bags of recycled plastic particles at a time, adapting to bags of recycled plastic particles of different sizes, without the need to frequently replace the clamps, thereby improving the flexibility and efficiency of automatic palletizing;

[0045] During clamping, the piston rod of the first cylinder 17 pushes the U-shaped block 18 to move, so that the first cylinder 17 rotates along the hinge seat 15 through the triangular block 16, and the U-shaped block 18 drives the L-shaped block 19 to rotate. The L-shaped block 19 pushes one of the rotating shafts 5 to rotate along the support 4, so that one of the rotating shafts 5 and the rotating sleeve 22 and the claw 6 thereon rotate, so that the pin sleeves 10 at both ends of the connecting rod 7 rotate along the pin shaft 11, and the claw 6 on the other side of the frame 1 rotates synchronously in the opposite direction, so as to clamp the bagged recycled plastic particles, thereby improving the clamping efficiency and reducing the use cost of palletizing after clamping;

[0046] During the clamping process, the vibration and impact of the connecting seat 3 during movement and clamping are reduced by the damping spring shock absorber 13; the baffle of the three-axis cylinder 20 pushes the pressing block 21 toward the bagged recycled plastic particles, and performs additional pressing or positioning operations on the bagged recycled plastic particles, thereby improving the stability and accuracy of clamping and stacking, and reducing the risk of collapse of the bagged recycled plastic particles after stacking.

[0047] Embodiment 2, as Figure 1 , Figure 4 and Figure 7 As shown, this embodiment is based on the previous embodiment, and differs from the previous embodiment in that the adjustment component 9 includes an electric push rod 902, a bracket 903 is fixedly provided on the outer wall of the fixed block 8, the outer peripheral wall of one end of the electric push rod 902 is installed on the bracket 903, a push block 904 is fixedly provided on the middle part of the outer wall of the clamping block 901, and the bottom surface of the piston rod of the electric push rod 902 is fixedly connected to the top surface of the push block 904; the push block 904 is pushed to move by the piston rod of the electric push rod 902, so that the push block 904 drives the clamping block 901 to move synchronously, and the clamping block 901 is adjusted to a suitable height for use.

[0048] A plurality of lifting rods 905 are fixedly provided on the top surface of the clamping block 901, and the lifting rods 905 are evenly arranged. A movable rod 906 is provided on the upper end of the fixed block 8. The upper ends of the plurality of lifting rods 905 are respectively fixedly connected to the movable rod 906, and the lifting rods 905 at both ends are respectively slidably connected to the lower end of the claw 6. A through groove 907 is provided on the top surface of the fixed block 8, and the lifting rods 905 located in the middle are respectively slidably connected to the fixed block 8 through the through groove 907; the plurality of lifting rods 905 slide along the claw 6 and the fixed block 8 respectively, thereby improving the stability of the movement of the clamping block 901.

[0049] When in use, before the palletizing operation begins, the piston rod of the electric push rod 902 pushes the push block 904 to move, so that the push block 904 drives the clamping block 901 to move synchronously, and the movement of the clamping block 901 drives the multiple lifting rods 905 to move synchronously, so that the multiple lifting rods 905 slide along the claws 6 and the fixed block 8 respectively, and the clamping block 901 is adjusted to a suitable use height, which is suitable for the clamping and palletizing of bagged recycled plastic particles of different sizes;

[0050] During the clamping process, the bagged recycled plastic particles are limited by the inner wall of the lifting rod 905, which reduces the possibility of the bagged recycled plastic particles falling during the movement and stacking process after clamping. At the same time, it is convenient to clamp and move multiple bagged recycled plastic particles to a suitable position for stacking, thereby improving the stacking stability and reliability of the bagged recycled plastic particles.
