Term explanation
Medium Bulk Containers: compound Medium Bulk Containers (hereinafter referred to as IBC container) is a kind of quilt interior at the international level
The industries such as food, biochemistry, medicine, chemical industry are used extensively to pack transfer container.Since IBC collecting barrelling can be repeated as many times as required
It uses, has apparent advantage in filling, storage and transportation and transport, and compared with drum, IBC collecting barrelling can save 35%
Storage space, size according to the ISO standard, are applicable not only to aseptic canning and cabinet are compact, deposit convenient for high-volume is safe and efficient
Storage, so largely apply to the transport of the forms material such as liquid, particle and thin slice, packaging, in storing process.Currently, existing rule
Lattice have tri- kinds of 820L, 1000L, 1250L, it is generally the case that its composed structure includes plastic inner container (inner lining bag), filling exit, row
Put device (valve or simple discharge outlet etc.), side plate, pedestal and cover board.
Crowded thruster of the invention includes at least a pair of crowded push piece, for example, at least two roller bearings, when needing to discharge in inner lining bag
Liquid when, two roller bearings are clamped into inner lining bag, under the drive of the drive, this performs relative motion crowded push piece, such as
Two roller bearings are done to be rotated backward relatively, is applied to inner lining bag and is squeezed thrust, to carry out squeezing row to the liquid in inner lining bag, in liquid
In discharge process, with the reduction of liquid in inner lining bag, two roller bearings decline simultaneously with liquid level automatically under the drive of the drive
Liquid squeeze and is pushed away.Herein, crowded thrust is referred to power effective object, such as inner lining bag and its interior accommodated liquid,
Extruding is generated simultaneously and pushes the power of effect.
As shown in Figs 1-4, squeezing thruster 1 includes a pair of of roller bearing 10, driving device 20 and mounting bracket 30.Roller bearing 10 can be rotated
Ground is installed on mounting bracket 30.Driving device 20 includes motor 21, gearbox 22 and control cabinet 26.The output axis connection of motor 21
In the input terminal of gearbox 22.The output end of gearbox 22 is connected to one of roller bearing 10.A pair of of roller bearing 10 is associated, thus one
The rotation of roller bearing can drive another roller bearing accordingly to rotate.Control cabinet 26 is electrically connected with motor 21 and is arranged to control motor
21 positive and negative rotation and revolving speed.A pair of of roller bearing 10 is correspondingly rotated forward or is inverted as a result,.Motor 21 can be permanent torque stepper motor
Or stepper motor.Using permanent torque stepper motor, regardless of motor speed changes, the torque for squeezing thruster is remained unchanged, and is shut out
General motor torque after speed reduction absolutely is inadequate, squeezes and pushes away not rotation situation.
The mounting portion 11 and the extruded segment 12 between mounting portion 11 that roller bearing 10 has both ends.In the present embodiment, pacify
Dress portion 11 is formed as one with extruded segment 12, but it can also be formed separately and fit together again.Roller bearing 10 is strip rod-like element,
Its size in axial direction is much larger than its size radially, and the length of mounting portion 11 is much smaller than extruded segment 12
Length.Extruded segment 12 with the bag body of inner lining bag 101 (as shown in figure 15) for contacting, so that bag body is squeezed, it further below can be detailed
Description.Roller bearing 10 includes support shaft 13 and the elastomer 14 for wrapping up support shaft setting.Mounting portion 11 is formed as the one of support shaft 13
Part.Preferably, elastomer is the elastic soft made of rubber, resin or other macromolecular materials etc..
Specifically, elastomer is cylindrical shape, has the internal cavity with the internal diameter of the major diameter fit of support shaft.Support shaft
It protrudes into the internal cavity of elastomer.The outer surface of support shaft can carry out gluing processing.Elastomer package is adsorbed in support shaft
Entire outer surface, thus under the drive of the drive support shaft rotate when elastomer rotate synchronously.Alternatively, elastomer passes through
The mode and support shaft of injection molding form one.
It should be understood that the elastomer of roller bearing 10 is also possible to other shapes, such as ellipse, triangle or rectangular
Deng.In the present embodiment, support shaft be it is substantially cylindric, i.e., its outer diameter is along being basically unchanged of axial direction, and the outer diameter of elastomer is along axis
To even variation, to form the elastomer with taper.But in other embodiments, the outer diameter of elastomer can also be along axial direction
Being basically unchanged, or only some along axial even variation.
In the present embodiment, mounting bracket 30 includes rear 31, two support frames 32 of pedestal and preceding pedestal 33,34.Pedestal afterwards
31 are made of two sub-bases 310 and the tight structure of locking.Retaining mechanism is for releasably locking two sub-bases.Two supports
Frame 32 links into an integrated entity rear pedestal 31 and preceding pedestal 33,34, i.e. the both ends of support frame 32 are connected to rear pedestal 31 with before
Pedestal 33.The thickness of pedestal 31 and preceding pedestal 33 is arranged to as small as possible afterwards, so that extruded segment is as long as possible.Support frame it is transversal
Face shape can be C font or the protective device for taking other shapes and structure, as long as it can at least surround the outer of roller bearing
Side, so that the lateral surface of roller bearing is separated with gripped object during crowded thruster is squeezed and pushed away.
One end of every roller bearing of two roller bearings is connected to a corresponding sub-base 310.One of pedestal 31 is provided with logical afterwards
Hole, another is provided with screw hole.Locking wrench 314 is threaded through through-hole and enters screw hole operationally to lock a pair of of roller bearing 10
Tightly, vice versa.Wherein, screw hole can be through-hole or blind hole.Above-mentioned through-hole, screw hole and locking wrench constitutes above-mentioned locking machine
Structure.Certainly, retaining mechanism can also use other way, such as by way of snap lock.
Preceding pedestal 33,34 is detachably mounted to the two sides of gear-box case 25 respectively.Preceding pedestal 33,34 is also respectively with two
One end of a support frame connects.The support shaft of one of a pair of of roller bearing 10 is connected to the output shaft of gearbox 22 by mounting portion 11,
And another mounting portion 11 is installed in rotation in preceding pedestal 33.Third tooth is also respectively connected in the mounting portion of two roller bearings
Wheel 15 and the 4th gear 16, can be intermeshed, so that the rotation of a roller bearing can drive another roller bearing to rotate backward.Rolling
The both ends of axis are respectively received in rear pedestal 31 and preceding pedestal 32,33 so that squeeze push away during, the end of elastomer will not be with
Gripped object (such as inner lining bag 101) contact.Therefore during crowded push away, elastomer be will not fall off.
