For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the automatic material-absorbing device of cable plastic extrusion machine, and it comprises material feeding chamber, storage compartment, conveying mechanism and detection controlling organization;

Conveying mechanism comprises heating component, filling tube, vacuum machine, vacuum tube, loopback pipe and triple valve, described heating component comprises heating collar and the heater being connected with heating collar, described vacuum tube is communicated with into T-shaped pipeline by three segment pipes and forms, these vacuum tube three segment pipe intersections are connected with a triple valve, three ends of this triple valve respectively with the corresponding connection of three segment pipes of vacuum tube, three segment pipes of described vacuum tube not link respectively with material feeding chamber interior, inside, storage compartment and vacuum machine are communicated with, be equipped with respectively screen pack in described material feeding chamber and storage compartment and vacuum tube connectivity part, material feeding chamber and bottom, storage compartment are communicated with by loopback pipe, top, described material feeding chamber is communicated with storage compartment by filling tube, the outer cover of this filling tube has heating collar, described filling tube middle part is also connected with switch valve.

Detect controlling organization and comprise level sensor, described level sensor is loaded in material feeding chamber interior walls, and the stuff level switch of this level sensor is electrically connected with switch valve.

Further, described storage compartment bottom outside is also provided with the door of energy switch.

Further, detect controlling organization and also comprise controller, described heater is electrically connected with controller, and the switch of switch valve and triple valve is all electrically connected with controller.

Advantage and the good effect that the utlity model has are: the efficiency that improves suction, control at any time as required suction flow velocity, grasp in time the quantity of feeding, and in control plastic grain, too much dust enters in extruding machine, in not needing that extruding machine is carried to plastic grain, also can dustless loopback put in raw stock chamber, whole device has improved the degree that automation is carried, and has reduced the process of artificial participation.

The specific embodiment

Below in conjunction with accompanying drawing and concrete embodiment, the utility model is further described.

As shown in the figure, the automatic material-absorbing device of cable plastic extrusion machine, it comprises material feeding chamber 1, storage compartment 9, conveying mechanism and detection controlling organization;

Conveying mechanism comprises heating component, filling tube 3, vacuum machine 8, vacuum tube 7, loopback pipe 11, switch valve 5 and triple valve 6, described heating component comprises heating collar and the heater being connected with heating collar, described vacuum tube 7 is communicated with into T-shaped pipeline by three segment pipes and forms, these vacuum tube three segment pipe intersections are connected with a triple valve 6, three ends of this triple valve respectively with the corresponding connection of three segment pipes of vacuum tube 7, three segment pipes of described vacuum tube not link respectively with 1 inside, material feeding chamber, 9 inside, storage compartment and vacuum machine 8 are communicated with, be equipped with respectively screen pack 4 in described material feeding chamber and storage compartment and vacuum tube connectivity part, material feeding chamber and bottom, storage compartment are communicated with by loopback pipe 11, 1 top, described material feeding chamber is communicated with storage compartment 9 by filling tube 3, the outer cover of this filling tube has heating collar, described filling tube middle part is also connected with switch valve 5,

Detect controlling organization and comprise level sensor 2, controller, described level sensor is loaded on 1 inwall of material feeding chamber, the stuff level switch of this level sensor is electrically connected with switch valve 5, and described heater is electrically connected with controller, and the switch of switch valve 5 and triple valve 6 is all electrically connected with controller;

Described storage compartment 9 bottom outside are also provided with the door 10 of energy switch.

The course of work of the present embodiment:

First opening switch valve, makes material feeding chamber and storage compartment be communicated with by filling tube, and then the switch opens of triple valve, its vacuum machine and material feeding chamber is communicated with;

Inject a large amount of plastic grains in storage compartment, then just can open vacuum machine, due to the unlatching of vacuum machine, the pressure of material feeding chamber interior is changed, plastic grain in storage compartment just can be transported in material feeding chamber by filling tube so, guarantee the flow velocity of plastic grain by controlling the work size of vacuum machine, when plastic grain is by filling tube, the heating collar of filling tube outer wrap is heated by the control of heater, plastic grain is because the heat of this heating collar carries out preheating to self, the work that this warm dissolves plastic grain to follow-up extruding machine brings benefit, the screen pack that vacuum tube and material feeding chamber connectivity part are provided with both can guarantee that plastic grain can not enter into vacuum tube, can also make the dust in plastic grain be adsorbed onto in screen pack, thereby play clean effect,

And the stuff level switch of level sensor in material feeding chamber is concordant with plastic grain time, stuff level switch will be opened, thereby drive the running of the switch of gauge tap valve, and switch valve is before opening, so now switch valve will be closure state, and switch valve closure can not be transported in material feeding chamber the plastic grain in storage compartment, thereby control the quantity of the plastic grain in material feeding chamber, can not cause too much injection;

And level sensor is electrically connected with controller, the position of the plastic grain that level sensor detects so will be transferred in controller, and controller will, according to setting, be grasped the unlatching of switch valve at any time, has guaranteed that the plastic grain in extruding machine can not run out of goods;

When maybe needing to change plastic grain when extruding machine is out-of-work, just the switch of triple valve can be adjusted to vacuum machine and storage compartment's connection, now can be along with the work of vacuum machine in storage compartment, the pressure of storage compartment is diminished, so the plastic grain not using in material feeding chamber will be transmitted back in storage compartment by loopback pipe, and the effect of playing with the screen pack of vacuum tube connectivity part in storage compartment is the same with the screen pack in material feeding chamber, and in storage compartment door effect be exactly both to have put into plastic grain, also can take out plastic grain.

Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model scope, within all should still belonging to this patent covering scope.
