Abstract

The invention discloses an automatic weighing device of a blanking device, wherein a negative pressure extract opening is arranged at the lower part of a feeding roller, of which the other side is provided with a tobacco inlet; a cylinder is arranged below the feeding roller; a connecting head of the cylinder flexible arm is connected with steel wires; after being guided, the steel wires are connected with a balance wire of a weighing sensor; a bunker and an opened valve plate are hoisted on the balance wire through a connecting plate and a control wire; the two sides of the bunker are provided with optoelectronic switches, below which a limiting block for controlling the displacement of the bunker is arranged; an outer cover support is arranged below the limiting block; and the tail end of the bunker is connected with a measuring case. The beneficial effects are as follows: the materials are supplied through rotating the feeding roller and extracting the negative pressure; the opening and closing of the bunker valve are controlled by the cylinder and the pulling wire; the weighing data is obtained by the weighing sensor so that the tobacco is accurately weighed; the machine materials are conveniently managed; and the tobacco block phenomenon is avoided because of adding a screen.

Description

The feeder automatic weighing device

Technical field:

The present invention is the improvement to YJ19 cigarette machine feeder, is specially adapted to YJ19 and YJ19E cigarette machine.

Background technology:

The feeder of traditional YJ19 series mainly is made up of charging aperture, blanking storehouse, inlet scoop, plate-turning door, material-falling hopper, and whole feeder door is in the top of cigarette machine; Charging aperture links to each other with the Pneumatic silk feeding mouth (most of cigar mills adopt Pneumatic silk feeding), and material-falling hopper links to each other with the cigarette machine batch meter, and the blanking storehouse is provided with material-level detecting device; When checkout gear finds that pipe tobacco is not at specified altitude; Send signal and open through system's control air draught valve, realize charging, pipe tobacco reaches specified altitude; Checkout gear sends signal and closes through system's control air draught valve, carries out intermittent feeding; And cigarette machine calculates and on the case checkout gear to be installed also, when it detects that pipe tobacco is at low level in the batch meter, sends signal to system, and the plate-turning door of control feeder is opened; Pipe tobacco on the feeder is fallen into batch meter, supply silk thereby realize connecting, its shortcoming is: can't clear up filter screen automatically; Frequent plug wire; When continuously supplying silk, pipe tobacco can't accurately be weighed, and the materials consumption of board is difficult to accurate measurement and management.

Summary of the invention:

Task of the present invention provides a kind of filter screen and is difficult for stopping up, and pipe tobacco can accurately be weighed, to the feeder automatic weighing device of board materials ability accurate Calculation.Task of the present invention is done in such a way that it comprises into silk mouth, hopper, motor and support, is characterized in that: blade and turning cylinder are housed in the feed cylinder; The bottom of feed cylinder has the negative pressure ventilation mouth, is the pipe tobacco inlet at the opposite side of feed cylinder, and cylinder is equipped with in feed cylinder below; Be connected with steel wire on the connector of cylinder telescopic arm, steel wire is connected with the LOAD CELLS balanced line after leading, and balanced line is lifted with the valve plate of hopper and unlatching through connecting plate and control line; Optoelectronic switch is equipped with in the hopper both sides; The limited block of control hopper displacement is equipped with in the optoelectronic switch below, and the limited block below has outer cover to support, and the end of hopper is connected with a metering casing.Filter screen is equipped with in bleeding point and feed cylinder junction, blade and feed cylinder inner wall sealing, and the turning cylinder in the feed cylinder is by driven by motor, and directive wheel is contained in the center of support, and limited block and outer cover are fixed.The feed roller shelves is contained on the frame, and motor is fixed on the frame, and cylinder is fixed on the frame, and outer cover is fixed on the frame.The present invention has following effect: the supply of material is to accomplish through the rotation of feed cylinder and negative pressure extracting; The folding of hopper valve plate is by cylinder and backguy control; The data of weighing are to be drawn by LOAD CELLS, thereby ensure that pipe tobacco can accurately weigh, and are convenient to the management to the board materials; Owing to increased screen cloth, thereby stopped the generation of plug wire phenomenon.

Description of drawings:

Fig. 1 is a structural representation of the present invention;

Fig. 2 is that the side of Fig. 1 is shown structural representation;

Fig. 3 is the structure for amplifying sketch map of the A-A direction of Fig. 1.

Drawing explanation: 1, feed cylinder 2, cylinder 3, motor 4, LOAD CELLS 5, balanced line 6, control line 7, outer cover 8, hopper 9, support 10, optoelectronic switch 11, limited block 12, outer cover support 13, optoelectronic switch 14, valve plate 15, metering casing 16, directive wheel 17, negative pressure ventilation mouth 18, advance silk mouthfuls 19, connecting plate 20, screen cloth

The specific embodiment:

Describe embodiment in detail in conjunction with accompanying drawing, 1 on feed cylinder is contained on the frame, and feed cylinder bottom has negative pressure axle gas port 17, is silk mouthfuls 18 at the opposite side of feed cylinder; 4 blades and turning cylinder are housed in the feed cylinder, and blade and feed cylinder inner wall sealing, turning cylinder are equipped with screen cloth 20 by driven by motor in the junction of negative pressure ventilation mouth and feed cylinder; Motor is fixed on the frame, and feed cylinder below is equipped with cylinder 2, and cylinder is fixed on the frame, is connected with steel wire on the connector of cylinder telescopic arm; In the center of support 9 directive wheel 16 is housed, steel wire is therefrom walked around and is connected with balanced line 5 with LOAD CELLS 4, and balanced line has 4, and 2 balanced lines are lifted with hopper 8 through connecting plate 19; Other 2 balanced lines are lifted with the valve plate 14 that can open through control line 6, and optoelectronic switch 10 is equipped with in the hopper both sides, and the limited block 11 of control hopper displacement is equipped with in the optoelectronic switch below, and the limited block below is that outer cover supports 12 and fixing with outer cover 7; The hopper end is connected with metering casing 15, and the metering casing is fixed on the support 9, and during work, the negative pressure in the feed cylinder is extracted out by the negative pressure ventilation mouth; Pipe tobacco gets in the feed cylinders from advancing silk mouth 18, and filter screen is equipped with in negative pressure ventilation mouth and feed cylinder junction, pipe tobacco is separated between the blade of feed cylinder, in the drive lower drive shaft drive blade rotation of motor; When pipe tobacco thereupon during blade rotation to feed cylinder bottom, negative pressure is broken off, and pipe tobacco and atmosphere fall in the hopper 8 by gravity; This moment cylinder operation, steel wire is through directive wheel, will lead with LOAD CELLS, balanced line, control line strain, hopper is in vacant state; Valve plate is closed under the effect of control line, when pipe tobacco is filled to optoelectronic switch, and the motor stall; Feed stops, and program begins to weigh, the end of calculating, weigh; Cylinder moves right, and balanced line falls through the hopper of gusset piece lifting, when falling certain altitude; Supported by the spacing outer cover that is supported on of limited block, when two balanced lines continued to move down into the metering casing through control line in addition, control line unclamped; Valve plate is opened, and pipe tobacco drops down onto in the metering casing, accomplishes a blanking, weighs, counts and drop down onto the action of measuring casing.
