Abstract

This packing machine metering devices comprises of a container that can input the materials to a conveyer that is driven by a motor and sends the materials (like tea, bathing herb or soap noodles) to the end of the conveyer to drop into a weight hopper that connects to a weighing device. When the material weight reaches to the pre-set quantity, a pulling rod which is driven by an electromagnetic valve opens the weight hopper to let the material drop to complete the successive packing with consistent operation and precise calculation.

Description

The gauging device of wrapping machine

Technical field

The present invention relates to a kind of gauging device of wrapping machine, be mainly a kind of wrapping machine with meter Weight apparatus.

Background technology

The main purpose of " wrapping machine " is the usefulness for the raw material packing, and by should " wrapping machine " being distributed into bag with being scheduled to an amount of raw material; And raw material can be tealeaves or bathe medicinal material or soap silk etc.

Prior art comprises:

1. after raw material must be weighed with manual type, place packaging bag that raw material is carried out package handling again, its shortcoming is, can not reach the operation task of consistentization, serious waste labor hour and cost.

2. with mode of oscillation measuring cup is filled up metering with measuring cup, its shortcoming is that its metering only is the summary value, and raw material not simultaneously its volume and heavy certainly will be different, so must measure the replacing measuring cup again; Is example as list with packing tealeaves, it does not make in flow process degree of drying and kneads mode (rubbing into strips or bulk) and needs different tealeaves simultaneously according to its kind, the aqueous ingredients in the tealeaves is promptly not different simultaneously when degree of drying, its weight will be different, the mode of rubbing into is not simultaneously, strip must be different with its volume potential of bulk, so must measure the replacing measuring cup again.

The present invention is a kind of gauging device (as shown in Fig. 1～3) of wrapping machine, further with preferred embodiment as shown in drawings, describes in detail as the back:

Wrapping machine is provided with a container containing 10, and its inside can supply splendid attire raw material (as being tealeaves or bath medicinal material or soap silk etc.), and the downside of this container containing 10 has opening;

One in the form of a ring and have a load-transfer device 20 of suitable length, and it can be a pair of face dentation load-transfer device in this load-transfer device 20;

One motor 30, it can be stepper motor or servomotor, in output place of motor 30 gear cluster 31 is set, and it can be connected with a driving wheel 32 for a train of reduction gears 31 this gear cluster, this driving wheel 32 can be a dentation driving wheel 32, can drive dentation load-transfer device 20 exactly and rotate;

One follower 33, it can be a dentation follower 33 this follower 33, be arranged at the in addition side of dentation load-transfer device 20, it can be driven and rotate by dentation load-transfer device 20, and the both sides that are positioned at driving wheel 32, follower 33 and dentation load-transfer device 20 are provided with a

side plate

34,35 longitudinally respectively;

The swash plate 40 that takes the shape of the letter U, its both sides are fixedly arranged on the end of

side plate

34,35 respectively, and this swash plate 40 also is positioned at the place, terminal below of dentation load-transfer device 20;

One platform 41 is arranged at

opposing sideplates

34,35 downside places, and platform 41 downsides are provided with number a bracing frame 42 and a horizontal stay bearing plate 43 longitudinally;

One loading source 50, it can be electronic type weighing apparatus (electronic instrumen) or Automatic balance (automatic weighing instrument), be fixedly arranged on and be positioned at platform 41 downsides on the stay bearing plate 43, this loading source 50 has the function that can weigh, for raw material is weighed;

One bucket 60, stationary hopper 61 with two relative U-shapeds is formed with control hopper 62, form the bucket 60 of a upper end open lower end closed, be pivoted mutually between the two and form fulcrum 63, stationary hopper 61 downside settings are oblique catch 611 (as shown in Figure 4), control hopper 62 downsides have the opening 621 (as shown in Figure 5) that raw material can be dropped out, and in control hopper 62 upsides one control stalk 622 that is protruded out by the inboard are set outwardly, and the stationary hopper outside is fixed on the loading source;

Electromagnetic valve 70 is arranged on the stay bearing plate 43, and L-shaped pull bar 71 is set on the

electromagnetic valve

70,71 actions of this pull bar of these electromagnetic valve 70 may command, and the upside of pull bar 71 also is positioned at the outside of control stalk 622.

As Fig. 1,3, shown in 4, after the combination by said structure, when using, the present invention mainly can be with raw material (as tealeaves or bath medicinal material or soap silk etc.), by the end upside of container containing 10 blanking down to dentation load-transfer device 20, drive train of reduction gears 31 through motor 30, driving wheel 32 and dentation load-transfer device 20 is rotated, follower 33 is also driven and rotates by dentation load-transfer device 20, so that raw material is carried after by the previous dynasty, the end that raw material is delivered to dentation load-transfer device 20 can drop down, landing is to bucket 60 inside via swash plate 40, the raw material hopper 61 that is fixed, catch 611 and control hopper 62 splendid attires are in bucket 60 inside, at this moment, can begin bucket 60 and in-to-in raw material thereof are weighed by loading source 50, if weight has reached about 70% of preset weight, automatic control circuit can give motor 30 signals and reduce its rotating speed, make dentation load-transfer device 20 slow down its delivery speed, one when raw material weight reaches default weight, stop motor running, then, the downside of bucket 60 is opened, in the usefulness of falling material.

As shown in Figure 5, being bucket 60 downsides opens, and the section-drawing that can fall to expect down, this electromagnetic valve 70 can order about L-shaped pull bar 71 and pull back, and makes pull bar 71 pulling control stalks 622, and control hopper 62 pivots with fulcrum 63, the opening 621 of control hopper 62 downsides is opened with respect to catch 611, at this moment, can raw material is inner and along the inclined-plane of catch 611 and landing down, so that the follow-up operation that is packaged into bag with packaging bag by bucket 60.

Therefore, the present invention utilizes under the aforesaid space structure kenel, setting by said structure, can reach and make wrapping machine after feeding, before being packaged into bag,, and can reaching and measure purpose accurately, then by certain weighing, be packaged into the operation of bag again, and can reach consistentization operation to save the purpose of labor hour and cost.
