Description

Technical Field

[0001] This invention relates to equipment for processing expandable polystyrene waste, and in particular to a cutting and collecting device for expandable polystyrene waste blocks. Background Technology

[0002] In the production of expandable polystyrene, liquid waste is generated for various reasons. This liquid waste is discharged into a waste pool. After it solidifies into a block, operators enter the pool and use chainsaws or other cutting tools to cut the waste block into smaller pieces, which are then removed from the waste pool. This entire cutting process requires a large amount of manual labor, is time-consuming and labor-intensive, has low processing efficiency, and using chainsaws poses a low safety risk. Summary of the Invention

Each set mainly comprises a left gripper 21-1, a right gripper 21-2, a lower ear plate 21-3, a pin 21-4, a bushing 21-5, an upper ear plate 21-6, and a gripper electric push rod 21-7. The adjustment assembly 22 mainly comprises an adjustment guide rail 22-1, an adjustment slider 22-2, an adjustment screw 22-3, and an adjustment nut 22-4.

[0052] The gripper support plate 20-1 has symmetrically formed long slots on both the front and rear sides of its left and right ends. Adjustment guide rails 22-1 are symmetrically installed on the front and rear sides of the two long slots. The cross-section of the adjustment guide rails 22-1 is dovetail-shaped, and each adjustment guide rail 22-1 has two adjustment sliders 22-2 installed on it. Lower ear plates 21-3 are welded to the upper part of the sliders 22-2 on both sides of the same long slot. A pin 21-4 passes between the two lower ear plates 21-3, and a bushing 21-5 is fitted onto the pin 21-4 between the two lower ear plates 21-3. The left gripper 21-1 and right gripper 21-2 are vertical straight rods with a square cross-section and a serrated structure on their inner surfaces to increase friction with the rectangular waste block. The left gripper 21-1 and right gripper 21-2 are symmetrically positioned below the left and right long slots, and their upper ends are welded to the bushings 21-5. Upper ear plate 21-6 is welded to the upper part of bushing 21-5. Upper ear plate 21-6 is Y-shaped. A gripper electric push rod 21-7 is installed between the two upper ear plates 21-6 on the same side. The two ends of the gripper electric push rod 21-7 are connected to the upper ear plate 21-6 by hinge pins. Adjusting nuts 22-4 are welded to the outer sides of the two adjusting sliders 22-2 of the same adjusting guide rail 22-1 of each adjusting assembly 22. The two adjusting nuts 22-4 are screwed onto the two ends of the adjusting screw 22-3. The adjusting screw 22-3 has two sections of threads with opposite directions.

[0053] After the cutting mechanism 16 cuts the waste block into rectangular waste blocks, the rear lifting mechanism 19 aligns with the rectangular waste block and descends. The four grippers of the gripper assembly 21 extend into the gaps of the rectangular waste block, the gripper electric push rod 21-7 extends, and the four grippers grip the rectangular waste block. The rear lifting mechanism 19 rises, the gantry 10 moves, and the gripper assembly 21 transports the rectangular waste block to the transport vehicle or hopper outside the waste pool 1. The gripper electric push rod 21-7 retracts, the four grippers open, and the rectangular waste block falls into the transport vehicle or hopper. Adjusting component 22 adjusts the opening between the jaws according to the size of the rectangular waste block. Rotating the adjusting screw 22-3 moves the two adjusting nuts 22-4 closer or further apart, adjusting the distance between the two adjusting sliders 22-2, the lower ear plate 21-3, the pin 21-4 and the bushing 21-5, thereby adjusting the distance between the left jaw 21-1 and the right jaw 21-2. The extension of the jaw electric push rod 21-7 is adjusted accordingly. Example 2

[0054] See Figures 14-18A suction cup mechanism 23 is installed on the gripper support plate 20-1. The suction cup mechanism 23 mainly consists of a lifting suction pipe 23-1, a lifting sleeve 23-2, a positioning rack 23-3, a suction cup 23-4, a negative pressure support hose 23-5, a connector pipe 23-6, a negative pressure main pipe 23-7, a negative pressure main hose 23-8, a negative pressure fan 23-9, a positioning gear 23-10, a fixed ear seat 23-11, an arc-shaped internal gear ring 23-12, a positioning cylinder 23-13, and a bracket 23-14. The gripper support plate 20-1 has symmetrically opened circular holes, in which the lifting sleeve 23-2 is installed. The lower end of the lifting sleeve 23-2 has a flange structure, which is embedded in the bottom surface of the gripper support plate 20-1 and connected to it by bolts. The inner wall of the lifting sleeve 23-2 has a sliding groove, and the vertical lifting suction pipe 23-1 passes through the lifting sleeve 23-2 and is slidably connected to it. A vertical positioning rack 23-3 is installed on the outer wall of the lifting suction pipe 23-1, and the positioning rack 23-3 is located in the sliding groove. A suction cup 23-4 is installed at the lower end of the lifting suction pipe 23-1. The upper end of the lifting suction pipe 23-1 is connected to one end of the negative pressure support hose 23-5, and the other end of the negative pressure support hose 23-5 is connected to the outer end of the connector pipe 23-6. The connector pipe 23-6 radially penetrates the column wall of the sliding column 14-2. A negative pressure main pipe 23-7 is installed inside the sliding column 14-2. A tee connector is installed at the lower end of the negative pressure main pipe 23-7, and the inner end of the connector pipe 23-6 is connected to the tee connector. A flange is welded to the upper part of the negative pressure main pipe 23-7, and the flange is screwed to the upper end face of the sliding column 14-2. The negative pressure main pipe 23-7 is connected to the negative pressure fan 23-9 through the negative pressure main hose 23-8. The negative pressure fan 23-9 is installed on the transverse platform 11. A rubber shock-absorbing ring is fitted at the lower end of the negative pressure main pipe 23-7 to reduce vibration in the negative pressure main pipe 23-7.

[0055] The positioning rack 23-3 meshes with the positioning gear 23-10. The positioning gear 23-10 is rotatably connected to the fixed lug 23-11 via an axle. The fixed lug 23-11 is mounted on the gripper support plate 20-1. An arc-shaped internal gear ring 23-12 is provided on the outer side of the positioning gear 23-10. The arc-shaped internal gear ring 23-12 is mounted on the end of the piston rod of the positioning cylinder 23-13. The outer end of the cylinder body of the positioning cylinder 23-13 is hinged to the positioning lug 23-18 via a positioning pin. The inner end of the cylinder body of the positioning cylinder 23-13 is provided with a bracket 23-14. The bracket 23-14 is U-shaped and has a vertical guide hole. A spring 23-15 is installed in the guide hole. A guide post 23-16 passes through the spring 23-15. An arc-shaped support plate 23-17 is welded to the upper end face of the guide post. The support plate 23-17 supports the cylinder body. An inverted U-shaped pressure ring can also be installed on the upper port of bracket 23-14 to give positioning cylinder 23-13 a certain amount of floating.

[0056] The suction cup mechanism 23 can be used independently. To increase safety and prevent rectangular waste blocks from falling, it can also be used in conjunction with the gripper assembly 21. When the direction of the rectangular waste block changes, the suction cup mechanism 23 can be used independently. When the rectangular waste block is being sucked up, the rear lifting mechanism 19 descends, the arc-shaped internal gear ring 23-12 disengages from the positioning gear 23-10, the positioning gear 23-10 rotates freely, the lifting suction tube 23-1 of the suction cup mechanism 23 descends, the suction cup 23-4 contacts the rectangular waste block, the negative pressure fan 23-9 starts, and the suction cup 23-4 adsorbs the rectangular waste block. The piston rod of the positioning cylinder 23-13 extends, and the arc-shaped internal gear ring 23-12 meshes with the positioning gear 23-10. The guide post 23-16 and the spring 23-15 allow the arc-shaped internal gear ring 23-12 to have a floating amount, ensuring accurate meshing between the arc-shaped internal gear ring 23-12 and the positioning gear 23-10. The arc-shaped internal gear ring 23-12 limits the positioning gear 23-10, stopping the positioning gear 23-10 from rotating. The positioning gear 23-10 positions the positioning rack 23-3, thereby positioning the lifting suction tube 23-1. The arc-shaped internal gear ring 23-12, the positioning gear 23-10, and the positioning rack 23-3 constitute the positioning structure. The positioning gear 23-10 bears the radial force, preventing the lifting suction tube 23-1 from deforming or jamming. The rectangular waste block is transported to the top of the transport vehicle or hopper. The negative pressure fan 23-9 releases the pressure, the rectangular waste block falls, the piston rod of the positioning cylinder 23-13 retracts, the positioning gear 23-10 rotates freely, the lifting suction pipe 23-1 and the positioning rack 23-3 descend, and the upper end of the positioning rack 23-3 is welded with a limiting block.

One-way valves are installed at the outlets of the high-pressure water pump 24-6 and the low-pressure water pump 24-7 respectively. During water pressure cutting, the high-pressure water pump 24-6 operates. When the cutting mechanism 16 is cutting, the low-pressure water pump 24-7 operates, spraying water onto the waste block to cool it down and prevent fire caused by the high pentane content of the waste block.

[0058] The cutting motor 16-1 of the present invention can also be equipped with a circular cutting saw blade 16-6, and the cutting motor 16-1 is horizontally mounted on the bracket 17-1.
