Embodiment 1

[0044] A paper-plastic separation-plastic-skin granulation production system for waste paper-plastic composite materials in this embodiment includes a paper-plastic separation device, an extrusion molding device, and a granulation device connected in sequence, and also includes a pulp Treatment units and fume treatment units connected to extrusion molding units; e.g. figure 1 As shown, the paper-plastic separation device includes a feed inlet A1, a material pushing mechanism 2, an extruder 3 and a friction mechanism 4. Both the material pushing mechanism 2 and the friction mechanism 4 are barrel structures, and the feeding inlet 1 is set on the material pushing mechanism. 2 and communicate with it, the extruder 3 is detachably installed on the other end of the material pushing mechanism 2; the friction mechanism 4 is connected with the discharge end of the extruder 3; as figure 2 As shown, the extrusion molding device includes a feed hopper 71, an extrusion mechanism 72, a fi...

Embodiment 2

[0053] The paper-plastic separation-plastic-skin granulation production system of waste paper-plastic composite material in this embodiment has the same basic structure as that of embodiment 1, except that the extruder 3 is a cross-knife structure; the material pushing mechanism 2 is a screw propulsion Type structure; friction mechanism 4 comprises water inlet 41, vertical angle screen 42, slurry outlet 44, plastic outlet 45 and motor A46, and water inlet 41 is arranged on the position above the left end of friction mechanism 4, and the volume of water in friction mechanism 4 is 60%% of the total capacity; the vertical angle sieve 42 and its motor A46 are inside the vertical angle sieve 42, and the motor A46 is fixedly arranged on the friction mechanism 4 axis at the right end. Friction blocks 43 are evenly arranged on the inner network wall; the pulp outlet 44 and the plastic outlet 45 are respectively arranged at the bottom of the friction mechanism 4 from left to right, and ...

Embodiment 3

[0062] A paper-plastic separation-plastic-skin granulation production system for waste paper-plastic composite materials in this embodiment, the basic structure is the same as that of embodiment 2, the difference is that the volume of water in the friction mechanism 4 is 70% of the total capacity; The inclination angle of the sieve 53 is 30 degrees, the number of revolutions is 2 revolutions per second, and the mesh number of the screen is 20 meshes; an automatic pounding rod is set on the feed hopper 71 to avoid blanking in the feed hopper 71 due to the relatively light plastic skin; The heater 722 is an electromagnetic heater; the extruding mechanism is provided with a temperature detection and monitoring mechanism connected to the PLC. The packaging mechanism 9 includes a collecting hopper 91 and a weighing and packaging platform 92. The upper end of the collecting hopper 91 communicates with the discharge pipe 87, and the outlet at the bottom end communicates with the weigh...

The waste paper-plastic composite paper-plastic separation and plastic-sheet granulation production system performs paper-plastic separation on waste cartons and comprehensive processing on separated crushed plastic sheets and pulp, and is suitable for paper-plastic separation of domestic dually-classified waste paper-plastic composites and comprehensive utilization of separated waste-paper-plastic composites.

Description

technical field [0001] The invention belongs to the technical field of waste carton treatment, in particular to a waste paper-plastic composite paper-plastic separation-plastic-skin granulation production system. Background technique [0002] With the rapid development of our country's economy, most of the packaging materials are made of various types of plastic films on cartons, which are printed and laminated. Paper-plastic composite materials are used. Applied to food packaging, the reuse of waste generated after being used has always been a big trouble that is difficult to deal with. Paper-coated and plastic-coated materials such as milk carton wrapping paper, coated paper, and PP bag labels must be removed during production or after use. Separated completely from plastic, otherwise it cannot be recycled. [0003] The recycling and reuse of waste paper-plastic composite materials is an important way to regenerate resources, but due to the different properties of paper a...
