A kind of wood powder pre-treatment conveying device
Technical field
The present invention relates to the equipment of processing toilet lid, specifically a kind of wood powder pre-treatment conveying device.
Background technology
Now conventional toilet lid production process comprises wood powder removal of impurities, wood powder gluing, hot-forming, japanning.And traditional wood powder processing is generally completed by hand by workman, workman is manual by wood powder material removing impurity, then to wood powder gluing, general all do not have wood powder this step dry, because containing many moisture in wood powder, after wood powder gluing, wood powder is easy to clump together, and causes the hot-forming toilet lid pressed out to have the part in fine and close part and cavity, and this just causes the toilet lid defect rate that processes very high.
And adopt traditional-handwork to operate to produce, the production efficiency of toilet lid is low, and the fabrication cycle of a general toilet lid needs the time of general one week, and production cost is higher.
Summary of the invention
The present invention is directed to prior art deficiency, provide a kind of wood powder pre-treatment conveying device, this wood powder pre-treatment conveying device can reduce the defect rate of toilet lid greatly, and reduces the production cycle, reduces production cost.
A kind of wood powder pre-treatment conveying device, comprise material feeding system, described material feeding system is connected with the first hopper, described first hopper is connected with vibratory sieve, described vibratory sieve has fines outlet, and also include wood powder pre-treatment drying device, described wood powder pre-treatment drying device comprises centrifugal blower, heater and hot-air duct, described centrifugal blower and described hot-air duct are connected to described heater both sides, and the fines outlet of described vibratory sieve is connected with described hot-air duct.
In technique scheme, preferably, described material feeding system comprises an end to end pipeline, end to end chain is provided with in described pipeline, described chain is provided with the some plectanes with the diameter matches of described pipeline, described pipeline is provided with the first feeding mouth, the first discharging opening and drive unit, described drive unit comprises sprocket wheel and the first motor, described sprocket wheel and described chain match, and described first discharging opening is positioned at above described first hopper.
In technique scheme, preferably, described heater comprises heat exchange cavity volume, and be provided with jet chimney in described heat exchange cavity volume, described jet chimney is connected with heat pump.
The present invention compared with prior art, there is following beneficial effect: the present invention adopts Cemented filling wood powder, the conveying and the drying that complete wood powder in the duct wait sequence of operations, replace manual operations originally, easily control the parameter of the humidity of wood powder etc. in the duct, not only shorten the process-cycle, and decrease the defect rate of product.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail: see Fig. 1 to Fig. 4, a kind of wood powder pre-treatment conveying device comprises material feeding system 101, described material feeding system 101 comprises an end to end pipeline 102, end to end chain 103 is provided with in described pipeline 102, described chain 103 is provided with the some plectanes 104 with the diameter matches of described pipeline 102, described pipeline 102 is provided with the first feeding mouth 102a, first discharging opening 102b and drive unit 105, described drive unit 105 comprises sprocket wheel 105a and the first motor 105b, described sprocket wheel 105a and described chain 103 match.In use, wood powder is put into the first feeding mouth 102a to this material feeding system by workman, and by the driving of drive unit 105, wood powder is transported to eminence from the first discharging opening 102b out by sprocket wheel 105a.
The first hopper 106 is provided with below first discharging opening 102b of described material feeding system 101, described first hopper 106 bottom is provided with extrusion device 107, vibratory sieve 108 is connected with below described extrusion device 107, described vibratory sieve 108 is provided with coarse fodder outlet 108a and fines outlet 108b, described coarse fodder outlet 108a is for discharging impurity and undesirable coarse flour, and described fines outlet 108b is for discharging qualified thin wood powder.In the present embodiment, described extrusion device 107 is one with the dwang of impeller, wood powder drops from the first discharging opening 102b and enters into the first hopper 106, then the wood powder rotated in promotion first hopper 106 by dwang is moved in described vibratory sieve 108, carries out the screening of wood powder in vibratory sieve 108.
Described fines outlet 108b is connected with described wood powder pre-treatment drying device 2, described wood powder pre-treatment drying device 2 comprises centrifugal blower 201, heater 202 and hot-air duct 203, in the present embodiment, described heater 202 comprises heat exchange cavity volume 202a, jet chimney 202b is provided with in described heat exchange cavity volume 202a, described centrifugal blower 201 and hot-air duct 203 are separately positioned on described heat exchange cavity volume 202a both sides, jet chimney 202b is connected with heat pump 204, described fines outlet 108b is connected with described hot-air duct 203, wood powder makes the moisture in wood powder evaporate by mixing with hot-air, thus realize wood powder drying, the degree of drying of wood powder can be regulated by the input quantity of steam regulation and the intake velocity of centrifugal blower 201, thus reach wood powder optimum humidity, thus the defect rate making toilet lid process reduces greatly.
