Abstract
The utility model provides a speed dibit filling valve of electronic weighing liquid filling machine, includes valve body, push rod, filling mouth, case feed inlet, and the filling mouth connects soon at the lower extreme of valve body, and the case is fixed at the lower extreme of push rod, and in valve body and filling mouth were arranged in to the push rod, lower piston fixed connection in push rod and the dibit stroke cylinder, the top of piston was located down to the last piston, and the equal slidable of last piston and lower piston is installed in the hole of cylinder block. Because the valve core in the fast-slow two-position filling valve is controlled by the two-stroke cylinder, the valve core is in the maximum filling section state at the initial filling stage, and when the filling weight is close to the preset filling weight, the two-stroke cylinder enables the valve core to be in the accurate small-section filling state, so that the valve core is more suitable for the requirements of an electronic weighing filling process.
Description
Technical field:
The present invention relates to a kind of fixed heavy filling machine that contains the aqueous material of soft grit, relate in particular to fast-slow two-position filling valve wherein.
Background technique:
At agricultural chemicals, chemical industry, coating, daily-use chemical industry, in the industries such as food, have in many liquid to be filled and all contain particulate matter, the material to be filled that has is a paste, adopt common plunger pump to come very easily jam of can, very easily cause the pump housing inner wall abrasion when especially can contains granule materials, and filling accuracy is not high, adopt weight can requirements such as single filling speed is difficult to reach accurately, for the material that has strict weight to require, can't meet the demands, can market presses for this class filling apparatus, and the fast-slow two-position filling valve is one of critical component in this equipment.
Summary of the invention:
In order to satisfy the can requirement of above-mentioned extraordinary material, goal of the invention of the present invention provides a kind of fast-slow two-position filling valve of electronic weighing and loading, it has quick can and two stations of meticulous can, can satisfy the functional requirement of electronic weighing filling process to filling valve by electric control box.
The fast-slow two-position filling valve of described electronic weighing and loading, comprise valve body 51, push rod 52, can mouth 53, spool 54, material feeding mouth 55, can mouth 53 is screwed in the lower end of valve body 51, spool 54 is fixed on the lower end of push rod 52, push rod 52 places in valve body 51 and the can mouth 53, push rod 52 is fixedlyed connected with the lower piston 63 in the dibit stroke cylinder 6, and upper piston 62 is positioned at the top of lower piston 63, and upper piston 62 and lower piston 63 all are slidably mounted in the endoporus of cylinder block 61.
Because the spool in the fast-slow two-position filling valve is controlled by double stroke cylinder 6, be in maximum can cross section state at can initial stage spool 54, when can during near predetermined can weight, dibit stroke cylinder 6 makes spool 54 be in accurate small bore bottling condition, make it more to adapt to the requirement of electronic weighing filling process, when can weight reached requirement, dibit stroke cylinder 6 made spool 54 be in buttoned-up status.
Description of drawings:

Fig. 2 is the structural representation of fast-slow two-position filling valve 5 among Fig. 1;
Among the figure: the 1-variable-frequency motor; The 2-gear pump; The 3-suction tube; The 4-carrier pipe; 5-fast-slow two-position filling valve; 6-dibit stroke cylinder; The 7-solenoid directional control valve; The 8-electric control box; The 9-electronic scale; The 10-filling bottle; 11-school bottle apparatus; The 51-valve body; The 52-push rod; 53-can mouth; The 54-spool; The 55-material feeding mouth; The 61-cylinder block; The 62-upper piston; The 63-lower piston.
Embodiment:
Below in conjunction with description of drawings the specific embodiment of the present invention:
Embodiment 1: as shown in Figure 1, in electronic weighing and loading, contain variable-frequency motor 1, gear pump 2, suction tube 3, carrier pipe 4, fast-slow two-position filling valve 5, dibit stroke cylinder 6, solenoid directional control valve 7, electric control box 8, electronic scale 9, filling bottle 10 and school bottle apparatus 11, suction tube 3 is fixedly mounted on the material sucking port of gear pump 2, carrier pipe 4 one ends link to each other with fast-slow two-position filling valve 5, the other end links to each other with the discharge port of gear pump 2, gear pump 2 is driven by variable-frequency motor 1, dibit stroke cylinder 6 is installed on the fast-slow two-position filling valve 5, dibit stroke cylinder 6 communicates with compressed gas source by two solenoid directional control valves 7, electronic scale 9 is positioned at the below of fast-slow two-position filling valve 5, filling bottle 10 is placed on the electronic scale 9, two solenoid directional control valves 7, electronic scale 9 all links to each other with electric control box 8 with variable-frequency motor 1, and school bottle apparatus 11 is distributed in the both sides of filling bottle 10 symmetrically; Described solenoid directional control valve 7 is two position-5 way valves; Described fast-slow two-position filling valve 5 comprises valve body 51, push rod 52, can mouth 53, spool 54, material feeding mouth 55, can mouth 53 is screwed on the valve body 51, spool 54 is fixed on the lower end of push rod 52, push rod 52 places in valve body 51 and the can mouth 53, push rod 52 is fixedlyed connected with the lower piston 63 in the dibit stroke cylinder 6, upper piston 62 is positioned at the top of lower piston 63, and upper piston 62 and lower piston 63 all are slidably mounted in the endoporus of cylinder block 61.
Its pouring process is as follows:
The filling bottle 10 of the bottle-conveying mechanism input of filling machine is pushed on the electronic scale 9 fast by school bottle apparatus 11, weigh up bottle weight, this signal input electric control box 8, electric control box 8 is to variable-frequency motor 1 then, two solenoid directional control valves 7 send corresponding electric signal, make variable-frequency motor 1 in running order, make upper piston 62 and lower piston 63 in the dibit stroke cylinder 6 all be in the propelling position, make the spool 54 of push rod 52 lower ends be in the limit position that moves down, can cross section maximum between this moment can mouth 53 and the spool 54, when can during near predetermined can weight, electronic scale 9 is to electric control box 8 input relevant informations, and control dibit stroke cylinder 6, it is the next motionless that upper piston 62 is in, move on the lower piston 63, thereby reduce the can cross section between can mouth 53 and the spool 54, realize slow can, when can weight reaches prearranging quatity, electronic scale sends electrical signal to electric control box 8, make the two-piston up and down 62 in the dibit stroke cylinder 6,63 all reset, be in upper, can cross section complete closed between can mouth 53 and the spool 54 by the bottle-conveying mechanism bottle output that can is good, enters Cover whirling Machine more at this moment.
