Abstract
The utility model discloses a production PVC automatic feed system for tubular product, including former feed bin and the buffering storehouse of connection in former feed bin bottom, the bottom in buffering storehouse is connected with screw conveyer, is connected with the metering tank at screw conveyer's discharge end, the discharge gate department of metering tank is provided with the pneumatic valve, is connected with the mixer in the discharge gate below of metering tank, is equipped with weighing transducer in the metering tank, weighing transducer and screw conveyer's servo motor is respectively through conductor wire and switch board electric connection. The utility model discloses a metering tank interior weighing transducer measure, gathers weight signal transmission by weighing transducer and give the switch board, and the switch board makes at the uniform velocity feed of screw conveyer according to the servo motor's of the change adjusted spiral conveyer of measurement rotational speed, and until feed accuracy to the volume of establishing basis weight back, the servo motor power that cuts off screw conveyer stops the feed, guarantees that the measurement is accurate to guarantee product quality's stability.
Description
Technical field
This utility model relates to a kind of feeding system, more specifically, particularly relates to a kind of production PVC automatic feeding system.
Background technology
In existing production PVC automatic feeding system, raw material enters after stirring cage, joins double-speed motor to feed in measuring tank by reductor, rotating speed not easy-regulating due to motor, cause that metering is inaccurate, there is error, cause the PVC unstable product quality of extrusion molding.
Utility model content
The purpose of this utility model is in that for above-mentioned the deficiencies in the prior art, it is provided that a kind of production PVC automatic feeding system that can accurately measure, it is ensured that the stability of product quality.
For achieving the above object, the technical solution adopted in the utility model is: a kind of production PVC automatic feeding system, including raw material cabin and be connected to the surge bunker bottom raw material cabin, the bottom of described surge bunker is connected to conveying worm, discharge end at conveying worm is connected to measuring tank, the discharge outlet of described measuring tank is provided with pneumatic operated valve, discharging opening at measuring tank has been connected below blender, being provided with weight sensor in measuring tank, the servomotor of described weight sensor and conveying worm is electrically connected with switch board respectively through wire.
This utility model is measured by the weight sensor in measuring tank, by weight sensor, the weight signal collected is transferred to switch board, switch board adjusts the rotating speed of the servomotor of conveying worm in time according to the change of metering, make conveying worm at the uniform velocity feed, until after feed is accurate to setting weight, switch board sends control signal and cuts off the servo motor power supply of conveying worm, conveying worm is made to stop feed, ensure accurate measurement, thus ensureing the stability of product quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-raw material cabin；2-surge bunker；3-conveying worm；4-measuring tank；5-pneumatic operated valve；6-blender；7-weight sensor；8-switch board.
Detailed description of the invention
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but is not intended that any restriction of the present utility model.
As shown in Figure 1, a kind of production PVC automatic feeding system provided by the utility model, including raw material cabin 1 be connected to the surge bunker 2 bottom raw material cabin 1, it is connected to conveying worm 3 in the bottom of surge bunker 2, discharge end at conveying worm 3 is connected to measuring tank 4, the discharge outlet of described measuring tank 4 is provided with pneumatic operated valve 5, discharging opening at measuring tank 4 has been connected below blender 6, being provided with weight sensor 7 in measuring tank 4, the servomotor of described weight sensor 7 and conveying worm 3 is electrically connected respectively through wire and switch board 8.
In the production process of PVC, when adopting this utility model feed, raw material is stored in raw material cabin 1, conveying worm 3 is entered after the buffering of buffered storehouse 2, then under the effect of conveying worm 3, it is sent to measuring tank 4, and measured by the weight sensor 7 in measuring tank 4, the weight signal collected is transferred to switch board 8 by weight sensor 7, switch board 8 adjusts the rotating speed of the servomotor of conveying worm 3 in time according to the change of metering, make conveying worm 3 at the uniform velocity feed, until after feed is accurate to setting weight, switch board 8 sends control signal and cuts off the servo motor power supply of conveying worm 3, conveying worm 3 is made to stop feed, ensure accurate measurement, finally open pneumatic operated valve 5, various raw materials in measuring tank 4 enter in blender 6 and are stirred, make raw material Homogeneous phase mixing.
In this utility model example, described raw material cabin 1, surge bunker 2 and conveying worm 3 are equipped with two sets, and the discharge end of two set conveying worms 3 is all connected with measuring tank 4, is overlapped conveying worm 3 alternatingly feed by two.
Claims (2)
