Description
Technical field
The present invention relates to the cold pressing technical field of structures of recovery machine of foaming waste plastics, refer more particularly to the cold pressing cold press device of recovery machine of the waste plastics that is used for foaming.
Background technology
Foam waste plastics (expanded polystyrene (EPS) EPS, polyethylene foamed EPE etc.) because of its special molding mode, and have characteristics such as excellent in cushioning properties, thermal insulation, water proofing property and buoyancy.It mainly also is used as packaging material, food containers etc. except as constructional heat-insulating, smallpox sheet material, the engineering materials.But, caused comparatively serious white pollution because of it is difficult for characteristic aging and that be difficult to degrade.In addition, because air content is big in its volume, resinous principle is less, so its bulky, inconvenience transportation has caused very big difficulty to its recycling.Now before the foaming waste plastics recovery, can use the recovery machine of the colding pressing waste plastics that will foam to cold pressing reducing volume, thus convenient the transportation.
The existing foaming waste plastics recovery machine of colding pressing, its cold press device comprises extrusion device and compaction apparatus, described extrusion device comprises extrudes the storehouse, extrude and be provided with extrusion screw rod in the storehouse, described extrusion screw rod is by motor-driven, described compaction apparatus comprises the typing groove that is connected with the discharge end of extruding the storehouse, and the top movable of typing groove is provided with the typing lid, and described typing lid is to adopt manual mode to control.During work, after the foaming waste plastics that need cold pressing enters and extrudes the storehouse, the driven by motor reductor, reductor drives extrusion screw rod and pushes material to the groove of finalizing the design, after material enters the typing groove, adopt manual mode to control the typing lid, thereby realize compressing up and down the purpose of material.Its shortcoming is: owing to adopt manual adjustments typing lid, so be difficult to guarantee the uniformity of the compacted back of material density, and when the material of typing in the groove pressed density when excessive, extrusion screw rod continues forward, and convey materials can compare difficulty, the putty phenomenon promptly occurs, operate even can cause foaming waste plastics heat to melt for a long time, make motor the stall phenomenon occur, thereby the electric current that causes motor strengthens and motor is burnt out, thereby the foaming waste plastics recovery machine of colding pressing can't be run well.
Summary of the invention
Technical problem to be solved by this invention is: a kind of cold press device that is used for reclaiming the recovery machine of colding pressing of foaming waste plastics is provided, can guarantees the uniformity of the compacted back of material density and the recovery machine of colding pressing can can't not run well because the putty phenomenon occurring.
For addressing the above problem, the technical solution used in the present invention is: the foaming waste plastics cold press device in the recovery machine of colding pressing, comprise extrusion device and compaction apparatus, described extrusion device comprises extrudes the storehouse, extrude and be provided with extrusion screw rod in the storehouse, described extrusion screw rod is by motor-driven, described compaction apparatus comprises the typing groove that is connected with the discharge end of extruding the storehouse, the top movable of typing groove is provided with the typing lid, described typing lid is connected with the motion bar of oil cylinder, described oil cylinder by support be arranged on the typing groove the top, also be provided with the hydraulic means that is used to control oil cylinder on the described support.
Described motor is connected with reductor, and reductor is connected with reducer pedestal, and reducer pedestal is connected with bearing block, bearing block with extrude the storehouse and be connected, an end of described extrusion screw rod is arranged in the bearing block.
The invention has the beneficial effects as follows: after the foaming waste plastics is colded pressing and above-mentioned cold press device is installed in the recovery machine; owing to adopt oil cylinder and hydraulic means; the variation of the control signal of hydraulic means can be with the basis that is changed to of main current of electric; in the conforming while that guarantees the compacted back of material density; protected motor effectively, reclaimed the function normal operation thereby the foaming waste plastics is colded pressing.

The specific embodiment
Below by specific embodiment the present invention's cold press device that waste plastics colds pressing in the recovery machine that foams is described in further detail.
As shown in Figure 1, the foaming waste plastics cold press device in the recovery machine of colding pressing, comprise extrusion device and compaction apparatus, as shown in Figure 2, described extrusion device comprises extrudes storehouse 5, extrude and be provided with extrusion screw rod 6 in the storehouse 5, described extrusion screw rod 6 is driven by motor 1, described motor 1 is connected with reductor 2, reductor 2 is connected with reducer pedestal 3, reducer pedestal 3 is connected with bearing block 4, bearing block 4 with extrude storehouse 5 and be connected, an end of described extrusion screw rod 6 is arranged in the bearing block 4, as shown in Figure 3, described compaction apparatus comprises the typing groove 10 that is connected with the discharge end of extruding storehouse 5, the top movable of typing groove 10 is provided with typing and cover 11, and described typing lid 11 is connected with the motion bar of oil cylinder 8, and described oil cylinder 8 is arranged on the top of the groove 10 of finalizing the design by support 9, also be provided with the hydraulic means 7 that is used to control oil cylinder on the described support 9, the variation of the control signal of described hydraulic means 7 is with the basis that is changed to of motor 1 electric current.
Operation principle of the present invention is: after the foaming waste plastics that need cold pressing enters and extrudes storehouse 5, motor 1 drives reductor 2, reductor 2 drives extrusion screw rods 6 with the material groove 10 of pushing to finalize the design, after material enters typing groove 10, the motion bar of hydraulic means 7 control oil cylinders 8 stretches out, and is about to typing and covers 11 down pushings, constantly has material to be extruded screw rod 6 in the groove 10 of finalizing the design simultaneously and pushes, enter the material of typing in the groove 10 and constantly be finalized and cover 11 and compress, thereby reach the purpose of waste plastics of foaming of colding pressing.In the whole compaction process, the variation of the control signal of hydraulic means 7 is with the basis that is changed to of motor 1 electric current.When the material of typing in the groove 10 pressed density when excessive; extrusion screw rod 6 continues forward, and convey materials can compare difficulty; the putty phenomenon promptly appears; make motor 1 the stall phenomenon occur; thereby cause the electric current of motor 1 to strengthen; this moment, hydraulic means 7 was regained according to the motion bar of the variation control oil cylinder 8 of motor 1 electric current; being about to typing covers 11 and up lifts; thereby the feeding that makes extrusion screw rod 6 recovers smooth and easy; make the electric current of motor 1 reduce simultaneously thereupon; both protect motor 1, and can not cause foaming waste plastics heat to melt again.When motor 1 electric current recovers just often, hydraulic means 7 is controlled oil cylinder 8 again and will finalize the design and cover 11 down pushings, and and so forth, the compacted uniformity of density afterwards of waste plastics has finally guaranteed to foam.
