Description

Technical Field

[0001] The invention relates to the technical field of foamed polypropylene bead processing, in particular to a foamed polypropylene bead washing and drying device. Background Art

[0002] Foam plastics have the advantages of light weight, heat insulation, cushioning, insulation, corrosion resistance, and low price. Therefore, they are widely used in daily necessities, packaging, industry, agriculture, transportation, military industry, and aerospace industry. Since the 1990s, the development of foam plastics in my country has been very rapid. With the development of material technology, people have produced foamed polypropylene materials. Compared with traditional polyurethane (PU) soft and hard foam plastics, polystyrene (PS) foam plastics and polyethylene (PE) foam plastics, foamed polypropylene has better chemical resistance and thermal deformation, and is easier to recycle, which reduces the environmental pollution caused by foam materials. Therefore, plastic products processed and produced with foamed polypropylene as raw materials have been widely used.

[0003] During the production and processing of foamed polypropylene raw materials, the finished product is often in the form of beads. After the foamed polypropylene beads are formed, they need to be cleaned and dried to improve the cleanliness and dryness of the surface of the foamed polypropylene material, so as to prepare for subsequent processing and packaging procedures.

[0004] The existing method for cleaning expanded polypropylene beads is generally to put the expanded polypropylene beads into a cleaning liquid, and then to stir them with a stirring device so that the expanded polypropylene beads can more fully contact with the cleaning liquid to ensure the cleaning effect. However, the density of most expanded polypropylene beads is less than the density of the cleaning liquid, and they can only float on the cleaning liquid. In addition, after the surface of the expanded polypropylene beads contacts water, the viscosity increases and they will aggregate and clump. At this time, the expanded polypropylene beads will also adhere to the stirring device. Therefore, it is difficult to ensure the quality and effect of cleaning by stirring only with the stirring device. At the same time, the adhesion and agglomeration of the expanded polypropylene beads will also affect the subsequent drying effect. Therefore, a more effective expanded polypropylene bead cleaning and drying device is urgently needed. Summary of the invention

[0055] Working principle: Please refer to Figure 1-Figure 8 As shown, the foamed polypropylene beads to be cleaned are fed into the cleaning box 1 through the feed port 2, and then the foamed polypropylene beads slide down along the guide plate 5 into the cleaning liquid. At the same time, the drive motor is started to drive the first shift plate 7 to rotate through the roller 6 to shift the foamed polypropylene beads to the lower cleaning chamber 85.

[0056] Then, the first cylinder 81 is started to push the upper cleaning bin body 82 downward until it is tightly against the lower cleaning bin body 84, so that the foamed polypropylene beads can be enclosed in the upper cleaning chamber 83 and the lower cleaning chamber 85, and then the conveyor belt 86 is started to drive the second shift plate 87 to rotate so that the polypropylene beads in the upper cleaning chamber 83 and the lower cleaning chamber 85 are continuously moved, and then the first cylinder 81 is started to cooperate with the liftable bearing mechanism 88 to push the upper cleaning bin body 82 downward to the lowest point, so that the flowing foamed polypropylene beads can be more fully in contact with the cleaning liquid, and in the process of the upper cleaning bin body 82 and the lower cleaning bin body 84 moving downward, the door panel 811 closes the upper chamber door 89 and the lower chamber door 810 under the water flow pressure to ensure that the foamed polypropylene beads are cleaned for a sufficiently long time.

[0057] Then the first cylinder 81 contracts and cooperates with the liftable supporting mechanism 88 to drive the upper cleaning bin body 82 and the lower cleaning bin body 84 to move upward. At this time, the door panel 811 rotates in the direction away from the lower cleaning chamber 85 under the action of water flow pressure and its own gravity, so that the upper chamber door 89 and the lower chamber door 810 are opened. At this time, the conveyor belt 86 and the second shift plate 87 are cooperated to move so that the foamed polypropylene beads in the upper cleaning chamber 83 and the lower cleaning chamber 85 can be discharged in an orderly manner.

[0058] At this time, the second cylinder 925 is started to drive the electromagnetic plate 926 to move downward until it contacts and engages with the iron plate 927 on the rightmost rotating block 931, and then the second cylinder 925 drives the rightmost laying disk 91 to move upward, and then cooperates with the first motor 921, screw 922, slide rod 923 and top plate 924 to drive the rightmost laying disk 91 to move to the right, passing the stop block 9210 and the driving wheel 937 and approaching the lower cleaning chamber 85, so that the discharged foamed polypropylene beads are evenly laid on the laying surface of the laying disk 91 under the action of the pushing force of the second paddle 87 and the buoyancy of the cleaning liquid.

[0059] Then, the second cylinder 925 is started to drive the rightmost paving disc 91 to continue to move upward to the highest point, and then the rightmost paving disc 91 is driven to move to the left to just above the driving wheel 937 through the first motor 921, screw rod 922, sliding rod 923 and top plate 924, and then the second cylinder 925 is started to drive the rightmost paving disc 91 to move downward until the turntable 935 is tightly against the top of the driving wheel 937, and then the second motor 936 is started to drive the driving wheel 937 to rotate clockwise, and the driving wheel 937 drives the paving disc 91 to rotate counterclockwise through the turntable 935 and the positioning shaft 933 until the paving surface is in a horizontal position, and then the second cylinder 925 is started to drive the rightmost paving disc 91 to move downward until the turntable 935 is tightly against the top of the driving wheel 937, and then the second motor 936 is started to drive the driving wheel 937 to rotate clockwise. The driving wheel 937 drives the paving disc 91 to rotate counterclockwise through the turntable 935 and the positioning shaft 933 until the paving surface is in a horizontal position. A motor 921, a screw rod 922, a sliding rod 923 and a top plate 924 drive the rightmost placement disc 91 to move to the leftmost side. At this time, the placement disc 91 is located above the conveyor belt 928. At this time, the electromagnetic plate 926 is powered off, so that the rotating block 931 and the placement disc 91 fall on the conveyor belt 928. At this time, the conveyor belt 928 is started to drive the placement disc 91 through the discharge port 3 into the drying box 4, and then hot air is blown into the drying box 4 through multiple hot air pipes 41 to dry the foamed polypropylene beads in the placement disc 91. As above, the foamed polypropylene beads can be placed in all the placement discs 91 and sent to the drying box 4 for drying.

[0060] After drying is completed, the laying plate 91 is transported in the reverse direction into the cleaning box 1, and then the leftmost laying plate 91 is driven to move to the right to just above the driving wheel 937 by the first motor 921, the screw rod 922, the sliding rod 923 and the top plate 924.
