CN2173752Y - Liquid and paste food feeder - Google Patents

Abstract

The utility model relates to a liquid and paste food feeder with seedcases or seeds, which is mainly composed of a plunger pump, a feed valve, a discharge valve and an intermittent drive mechanism, wherein the feed valve and the discharge valve are composed of a fixed valve sheet with a feed hole and a rotary valve sheet with a discharge holes, which are tightly contacted. When the rotary valve sheet rotates intermittently, the feed hole and the discharge hole of two valve sheets are communicated or separated intermittently, namely, the valves are opened and closed intermittently. At the same time, the seedcases retained in the feed hole and the discharge hole can be cut off. Material can be absorbed into a cylinder body from a hopper or be extruded from the cylinder body to be sent into a package by using the reciprocating motion of a plunger and the alternate opening and closing of the feed valve and the discharge valve.

Description

Liquid and paste food feeder

Quantitative feed device when the utility model relates to a kind of packaging for foodstuff, particularly a kind of liquid state, paste food feed unit.

Can adopt weighting method and volumetry to carry out quantitatively feeding during the fluidised form packaging for foodstuff.But the paste food that has pericarp or seed for spicy sauce and so on, big because of its flowing power extreme difference, viscosity first, second because of containing more pericarp or seed, be easy to stop up valve, so up to the present still generally adopting the mode of hand charging packs, not only time-consuming taking a lot of work, and metering error is bigger, and capacity rating is lower.

The purpose of this utility model provide a kind of can the load-transfer device pericarp or aqueous, the paste food feed unit of seed.

Realize that the utility model purpose solution is: the intermittent drive mechanism of inlet valve, bleeder valve and charging and discharging valve that aqueous, the paste food feed unit that is provided links by plunger pump and driver train thereof, with plunger pump cylinder body is formed.Wherein the charging and discharging valve is made up of with the rotary valve plate that has discharge opening the fixedly valve block that has charging hole of two closed contacts, and the rotating shaft and the intermittent drive mechanism of rotary valve plate link, and fixedly the charging and discharging hole seamed edge of valve block and rotary valve plate is a tip-angled shape.The open and close state of charging and discharging valve is by the determining positions of rotary valve plate charging hole.When discharge opening on the rotary valve plate and charging hole on the fixing valve block are heavy mutually, valve opening; When interlacing, valve closing.Utilize intermittent drive mechanism that rotary valve plate is rotated to an angle at regular intervals, thereby valve is opened or closed once at regular intervals.The working process of this device is: inlet valve was opened when plunger retreated, and bleeder valve cuts out, and material is inhaled into plunger pump cylinder body through inlet valve.During plunger advancement, bleeder valve is opened, and inlet valve cuts out, and material is forced out through bleeder valve in cylinder body, delivers to packaging bag.Feeding to amount that material is each can be regulated by plunger stroke.Because the charging and discharging hole seamed edge on the valve block is a wedge angle, and two valve blocks are closed contact again, so when rotary valve plate rotated, relatively moving of the charging and discharging hole on two valve blocks just cut off scissors as same with pericarp or seed, avoided the phenomenon that pericarp or seed are stifled, block valve.

The intermittent drive mechanism of the charging and discharging valve in this device can adopt the various mechanism form, as pneumatic, hydraulic pressure or incomplete gear mechanism, but preferably adopt Geneva mechanism, so not only simple in structure, be easy to make, and structure is also compact, and reliability and accuracy are all better.

The plunger pump driver train of this device can adopt mechanisms such as pneumatic or hydraulic pressure, but preferably adopts cam mechanism.

The utility model so when carrying the band pericarp material of spicy sauce and so on, pericarp, seed can be cut off, has guaranteed the reliability of the unimpeded and valve working of material owing to adopted above-mentioned rotary charging and discharging valve.In addition, owing to adopt plunger pump suction, feeding, so this device is quantitatively accurately, and easy to adjust, compact conformation.This device not only can be carried paste, also can carry aqueous material.

Below in conjunction with accompanying drawing content of the present utility model is illustrated.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the A of Fig. 1 produces view to office.

As shown in Figure 1 and Figure 2: plunger pump 1 is made of cylinder body 2 and plunger 3.Plunger 3 is driven through connecting rod 5 by cam mechanism 4, and cam mechanism 4 is made up of two double-linked cams 6,7 and two rollers 9,10 of being installed on the same guide rod 8, and two rollers 9,10 match with two cams 6,7 respectively.Front wheel 9 cooperates with cam 6, in order to realize the forward movement of plunger 3.Rear roller 10 cooperates with cam 7, in order to realize the setback of plunger 3.The stroke of plunger 3 is by the distance decision of 9,10 on cam and two rollers, thus as long as regulate the spacing of two rollers 9,10, can the governing plunger stroke, give amount thereby regulate feeding of material.

Inlet valve 11 is identical with the structure of bleeder valve 12, by fixedly valve block 13, rotary valve plate 14 and spring 15 are formed.Fixedly valve block is provided with a charging hole 16, and rotary valve plate is provided with discharge opening 17, two valve blocks of two symmetries by spring 15 closed contacts.Geneva mechanism 21(claims Maltese cross again) to form by four groove sheaves 19 and crank 20, sheave 19 and rotary valve plate 14 are contained on the same axle 18.When speed reduction gearing 22 drives crank 20 rotations, sheave 19 will be done intermittently to rotate, and crank circles, and sheave changes 90 °, and promptly rotary valve plate 14 also changes 90 °, make valve batch (-type) ground open or close.When plunger 3 was positioned at the limit on the right-right-hand limit position, inlet valve 11 cut out, and bleeder valve 12 is opened, if plunger advancement can extrude material cylinder body 2.When plunger advancement arrived the left-limit position, inlet valve was opened, and bleeder valve cuts out, if plunger retreats, then material is inhaled in the cylinder body 2 from hopper 23.The revolution ratio of this example cam 6,7 and sheave 19 is 1:2.
