Description
Technical field
The utility model is related to a kind of batching devices, especially suitable for powdered or granular material dispensing, life
Technology of the package link is produced, Machine Design and field of electrical control are belonged to.
Background technology
The manufacturings such as chemical engineering of materials, food pharmaceutical at present, common demands carry out essence to particle or powder material, product
Really weighing and fast package.It is particularly directed to the special material and product that granularity is smaller, adhesive force is strong, in batch weighing, packaging
In the process, the requirement for packaging speed, weighing accuracy, dust removing effects is highlyer opposite.
Such as the not yet disclosed Chinese patent of the following earlier application of applicant, application No. is CN201721489127.X, names
Title is unloading auxiliary device, and major programme is hermetically socketed between the discharge port of storage bin hopper and the feed inlet of receiving hopper
Have and is flexible coupling；In the periphery being flexible coupling, it is provided with one group of clamping closing structure；Closing structure is clamped, includes one group of cylinder, with
And it is driven by the cylinder, along the one group of supporting rod diametrically reciprocated that is flexible coupling.Installation is connected with one on the piston rod of each cylinder
Oscillating bearing, an axis pin through one end of one group of crank and are fixed on oscillating bearing simultaneously, the side point of one group of supporting rod homonymy
It is not fixed on the other end of same group of crank；Installation is fixed by one group of fixing axle in the crank.
As described in said program, the axis pin of driving mechanism is in contact always with the crank of executing agency, connect, that is, exists
The active force of driving mechanism acts on weighing mechanism by the way that closing structure is clamped always during clamping is flexible coupling, this is by direct shadow
Ring the weighing accuracy to scale；In addition, after long-time use or under the premise of cylinder driving is hypodynamic, is controlled and be clamped by crank
The closure of bar can have certain gap, this results in material leakage and leads to subsequent production or pack the operating error of link.
In view of this, special propose present patent application.
Utility model content
Batching device described in the utility model, purpose of design be solve the above-mentioned problems of the prior art and
It proposes a kind of weighing mechanism of sound separation, that is, takes the driving device and the relatively independent peace of weighing mechanism of clamping closing structure
Dress, driving device is completely disengaged from during weighing, to improve and ensure weighing accuracy.
Another purpose of design is to form interference type clamping to be closed, to prevent from causing material leakage to be asked because imprecision is clamped
The generation of topic.
For the above-mentioned purpose of design of realization, the batching device includes：
One frame body, is mounted with scale on frame body, and the discharge port connection one of scale hooper is flexible coupling；
It is in place of difference with the prior art, the scale hooper, is installed on by hanging plate and the hanging of vertical pull rod
Scale；
One group of clamping closing structure is provided on frame body；
The clamping closing structure includes one group of cylinder, and is driven by the cylinder, is diametrically reciprocated along being flexible coupling
One group of supporting rod.
It is described based on above scheme, clamping closing structure is installed separately fixation with scale, is not on same mounting surface.
Material is put into during scale hooper, is weighed in the state that scale is in opposing stationary, weighing accuracy is higher.
To further improve weighing accuracy, meets the vibration shielding of requirements at the higher level, following prioritization scheme can be taken：
The clamping closing structure, on the piston rod of each cylinder installation be connected with an oscillating bearing, an axis pin is simultaneously
Through one end of one group of crank and it is fixed on oscillating bearing, the side of one group of supporting rod homonymy is individually fixed in same group of crank
The other end；
The crank is installed and is rotated about by one group of fixing axle；
On crank, it is provided with the sliding slot and circular hole back and forth slided for axis pin；Sliding slot is connected with circular hole, the internal diameter of circular hole
More than the width of sliding slot.
In above-mentioned improvement project, title is mounted on for the power source (cylinder or motor) of device for discharging in conventional weighing system
The vibration of present situation on batch box, the i.e. tracheae or cable and power source of driving device will have a direct impact on weighing accuracy.
From opening into closing course, axis pin is slided along sliding slot to circular hole supporting rod.When axis pin is slided into circular hole, pin
Axis is detached from the contact with crank, is also just detached from the transmission with the power of weighing part, therefore power from oscillating bearing, piston rod at this time
The vibration in source will not impact the weighing accuracy of scale.
At the beginning of installation, adjustable holding bar is to interference crossing condition, and closed state is relatively stable at this time, and material will not go out
Now spill.
After the completion of material weighing, axis pin along circular hole into sliding slot taxiing procedures, axis pin with crank from be detached to contacting, cylinder
It is stretched out by piston rod, oscillating bearing driving opens supporting rod, and then completes discharging operations.
Crank is driven to move back and forth by oscillating bearing for cooperation piston rod, it can be further between crank and fixing axle
It is provided with torsionspring.When crank is rotated around fixing axle, the twisting resistance of torsionspring has retracts becoming for original state by crank
Gesture.
In conclusion the utility model batching device has the following advantages：
1, a kind of weighing mechanism of sound separation is realized, can significantly improve and ensure weighing accuracy.
2, it is clamped and is closed using interference, the generation for leading to material leakage problem because imprecision is clamped can be effectively prevented.
3, during weighing, power source is separated with scale, thoroughly solves the shadow caused by weighing accuracy due to power source vibrates
It rings.
