Description
One, technical field
The utility model belongs to the plastic sheeting process equipment, and specifically a kind of single screw rod polyester plastics reclaims machine.
Two, background technology
Before the utility model was made, existing plastic recoverying equipment was the form processing of extruding that adopts twin-screw mostly, and film fragments is forced to be pressed into by feed screw, through in the same way or the incongruous double screw melt pelletization.There is following problem in dual-screw pelletizer:
1, twin-screw is extruded the component manufacturing process complexity, process-cycle is long, makes that the outfit of equipment cost is too high, useless film cost recovery height, lost the meaning that reclaims, leftover pieces that a large amount of medium-sized and small enterprises produce in having to produce and useless film are thrown away or undersell to Paint Factory etc.
2, because twin-screw needs quantitative feeding, and the bulk density of useless film fragment is low especially, has only about 0.01, can't satisfy the feeding requirement of twin-screw substantially.So general the recovery uses the extrusion capacity of twin-screw lower.As only 200 kilograms/hour of 92 common in the market unit extrusion capacities.
3, polyester plastics belongs to easy degradable material, and is all very responsive to water, heat, handles bad meeting product viscosity is fallen greatly, falls as viscosity to surpass 0.03, can influence the reuse effect, above 0.05, then can't reuse, and the use of can only demoting.And the twin-screw exhaust effect is poor, can't ensure the control accuracy that viscosity is fallen.
Three, summary of the invention
The purpose of this utility model provides a kind of efficient single screw rod plastic reliable, that can produce high-quality polyester regenerative granular material and reclaims machine.
The purpose of this utility model is achieved through the following technical solutions: a kind of single screw rod polyester plastics reclaims machine, it is characterized in that: it comprises that extruder, compacting machine, net-changing device, die head, tank, drying device, pelleter, vibrating device and wind send device, described extruder one end is connected with motor, and the other end is connected with die head by net-changing device; Compacting machine is arranged on the charging aperture place of extruder; The outlet of die head is connected with tank, and the other end of tank is connected with pelleter by drying device; The other end of pelleter send device to be connected by vibrating device and wind.
The utility model is provided with in the big L/D ratio the double gas of cooling and reclaims single screw rod in extruder, single screw rod low cost of manufacture, good exhaust effect can ensure the control accuracy that viscosity is fallen.Compacting machine adopts centrifugal cutting drawing-in device, and the material film fragment need not just can directly be got rid of in the extruder of side by drawing-in device through the granulation processing, and finally makes plastic grain by the plastics recovery machine.
The utility model will give up diaphragm after cutting, compacting through the PET that pulverizes, utilize centrifugal force to force to send into the machine of squeezing out, plasticizing, fusion in extruder, utilize vacuum system to discharge steam and impurity, pass through die forming then, in water after the cooling, be cut off to become and be suitable for the dry polyester plastics particle of back road shaping manufacturing procedure acceptable.Automatic speed regulation of the present utility model and temperature control system as system master equipment, adopt the novel touch screen operation with PLC, man-machine interface close friend, opening, and it is integrated to be convenient to system information simultaneously.By the communication of touch-screen and programmable device, realize the automatic control of each underlying device, but comprehensive management reclaims unit.Automatic control system can conveniently realize the setting of various technological parameters (plasticization temperature, running speed) and alarm parameters (safeguard protections such as material temperature, material pressure, current overload), control in real time, shows in real time and information storage.Compared with prior art, the utility model has the advantages that: 1, use extremely-low density film fragments compacting drawing-in device, guarantee the feeding capacity of film fragments, the while is exclusive segment moisture in advance, prevents to produce in extruding melting process degraded; 2, single screw rod of big L/D ratio, two exhausts can make film fragments fully plastify and remove moisture and impurity side by side; The dual channel automatic filtering unit can effectively be removed fine impurity, guarantees the film forming of later process; 3, the negative pressure drying device can effectively be got rid of the surface moisture of finished product particle, has guaranteed to reclaim the output and the quality of pellet, and energy consumption is low.
Four, description of drawings
Accompanying drawing is the utility model structural representation.
Five, the specific embodiment
A kind of single screw rod plastic described in the utility model reclaims machine, comprises that extruder 1, compacting machine 2, net-changing device 3, die head 4, tank 5, drying device 6, pelleter 7, vibrating device 8 and wind send device 9.Extruder 1 is by the motor transmission, and the other end is connected with die head 4 by net-changing device 3, is provided with to cool off double gas in the big L/D ratio and reclaim single screw rod in extruder 1, and single screw rod low cost of manufacture, good exhaust effect can ensure the control accuracy that viscosity is fallen.Net-changing device 3 can play the effect of impurity screening.Compacting machine 2 is arranged on the charging aperture place of extruder 1, and it adopts centrifugal cutting drawing-in device, and the material film fragment need not just can directly be got rid of in the side extruder 1 by drawing-in device through the granulation processing.Being used for the die head 4 that the Cast Strip is shaped is connected with tank 5, and the other end of tank 5 passes through drying device 6 and is connected with pelleter 7; The other end of pelleter 7 send device 9 to be connected by vibrating device 8 and wind.
During work, the material film fragment is directly got rid of in the side extruder 1 by drawing-in device 2, after the double gas of cooling reclaims single screw rod extruding in the process big L/D ratio, filter out impurity by net-changing device 3, and be shaped by die head 4 Cast Strips, the plastic tape film carries out drying by drying device 6 again and handles after cooling off through tank 5; Plastic tape film after super-dry is handled cuts into the plastics granule by pelleter 7, again by the screening of vibrating device 8, obtains the suitable plastic pellet of granular size, and last qualified plastic pellet send device 9 to transfer out via wind.Automatic speed regulation of the present utility model and temperature control system can adopt PLC as system master equipment, adopt the novel touch screen operation, man-machine interface close friend, opening, and it is integrated to be convenient to system information simultaneously.By the communication of touch-screen and programmable device, realize the automatic control of each underlying device, but comprehensive management reclaims unit.Automatic control system can conveniently realize the setting of various technological parameters (plasticization temperature, running speed) and alarm parameters (safeguard protections such as material temperature, material pressure, current overload), control in real time, shows in real time and information storage.
