Description
Technical field
The present invention relates to electronic-weighing measuring apparatus field, specifically relate to a kind of electronic belt tea scale.
Background technology
In many production lines of Tea Production enterprise, substantially all adopt belt conveyor line to transmit tea products, the tea products in course of conveying, generally all need to carry out online weight Weighing.Can be divided into according to metering object: just adopted the fresh tea leaf (former tea bag draws together spring tea and autumn tea) of getting off to enter production line, the semi-manufacture tea of manufacturing procedure process, and one-tenth to be packaged is sampled tea.Due to various tea quality and varying in weight, must by different weighing travelling speed.
Meanwhile, because the density of tealeaves is less, very light in weight, particularly has certain moisture when just adopting, friction force is larger again, easily bonding, accumulation, blocking.Especially at tealeaves before electronic belt scale, also will have one section of belt elevator, be elevated by tealeaves, material is at this moment a pile a pile, uneven, discontinuous.Now use general belt electronic scale, then easily cause hopper to block, uneven during blanking.If ordinary material blocking reaches the effect of blanking by vibrating bunker.But because tealeaves is abnormal soft, adopt the effect of vibration poor, particularly when hopper is comparatively large, when blanking velocity requires slower, vibration easily causes tealeaves inner heat in hopper thus affects the quality of tealeaves.
Summary of the invention

(2) technical scheme
For achieving the above object, the invention provides a kind of electronic belt tea scale, comprise hopper and transmission frame, described hopper comprises bucket body and feed opening, described transmission frame comprises transport tape and LOAD CELLS, and described LOAD CELLS is arranged on the below in described transport tape, and described hopper is placed in described transmission frame away from one end of manometric balance, be provided with roller bearing in described material body, described feed opening place is provided with feed opening size adjustment structure.
Further, described roller width is 0.3 to 0.6 of corresponding direction loading and unloading mouth length, and described roller is arranged on the At The Height of 0.5 to 1.5 the roller widths distances in described feed opening upper end.
Further, described transport tape thickness is 2mm to 3mm.
Further, described feed opening size adjustment structure comprises electric operator and hopper door, and described electric operator controls the motion of described hopper door.
Further, described lower electric operator is controlled by electric signal, and described electric signal to be compared according to its actual flow and set flow by the instrument in electronic belt tea scale and obtained.
Further, described transmission frame also comprises driving wheel and motor, the transmission successively of described motor, driving wheel, transport tape, by belt gear between described motor and described driving wheel, has multiple ratio of gear between described motor and described driving wheel.
Further, be eccentric installation when described roller bearing is installed.
Further, described roller bearing is cylindroid roller bearing.
(3) beneficial effect
Electronic belt tea scale of the present invention can regulate blanking velocity automatically, prevents hopper from blocking, and ensures tea leaf quality.

Fig. 1 is the one-piece construction schematic diagram of electronic belt tea scale of the present invention;
Fig. 2 is the structural representation of the transmission frame of electronic belt tea scale of the present invention;
Fig. 3 is the structural representation in a hopper direction of electronic belt tea scale of the present invention;
Fig. 4 is the structural representation in another direction of hopper of electronic belt tea scale of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
The structure of a kind of electronic belt tea scale of the present invention as depicted in figs. 1 and 2, comprise hopper 5 and transmission frame, described hopper 5 comprises bucket body and feed opening, described transmission frame comprises transport tape 2 and LOAD CELLS 3, described LOAD CELLS 3 is arranged on the below of described transport tape 2, described hopper 5 is placed in described transmission frame away from one end of manometric balance, is provided with roller bearing 7 in described material body, and described feed opening place is provided with feed opening size adjustment structure.
Described feed opening size adjustment structure comprises electric operator 4 and hopper door 6, and described electric operator 4 controls the motion of described hopper door 6.Described lower electric operator 4 is controlled by electric signal, and described electric signal to be compared according to its actual flow and set flow by the instrument in electronic belt tea scale and obtained.Wherein said instrument instrument the LOAD CELLS 3 in electronic belt tea scale and the tachogenerator in electronic belt tea scale are detected signal process, draw a flow value, then compare according to this flow value and set value, finally draw the numerical value that export.In the present embodiment, the electric signal of its output signal position 4 ~ 20mA.The telecommunications exporting 4 ~ 20mA is that hopper door 6 is opened or turned down to electric operator 4, according to obtained signal, reaches a metastable mobile equilibrium to make whole system to electric operator 4.
Because tealeaves is very light, for this reason, adopt thinner belt to carry, namely adopt the food belt only having 2 ~ 3mm, to reduce the impact of belt on tea-leaf weighing.
Described transmission frame also comprises driving wheel 12 and motor 10, described motor 10, driving wheel 12, transport tape 2 transmission successively, by belt 11 transmission between described motor 10 and described driving wheel 12, between described motor 10 and described driving wheel 12, there is multiple adjustable ratio of gear.General, the multiple belt wheel 1 varied in size of replaceable installation on described motor 10.
As shown in Figure 3 and Figure 4, described roller bearing 7 width D is 0.3 to 0.6 times of corresponding direction loading and unloading mouth length L, and described roller is arranged on the height H of 0.5 to 1.5 the roller widths D distances in described feed opening upper end in the mechanism of the hopper of electronic belt tea scale of the present invention.Because hopper 5 is wide at the top and narrow at the bottom, and tealeaves is more fluffy, there are bounding force, friction force, be easy to blocking, no matter hopper door 6 aperture has much, all may to result in blockage and can not blanking or ripple one ripple (a pile a pile) underground, roller bearing 7 to be installed for this reason in hopper 5 and can effectively to prevent tealeaves from blocking and tealeaves is piles and piles of falls.When installing roller bearing 7, described roller bearing 7 width D is 0.3 to 0.6 times of corresponding direction loading and unloading mouth length L is the best, and described roller is arranged on the height H of 0.5 to 1.5 the roller widths D distances in described feed opening upper end for best.In addition eccentric installation and roller bearing 7 is adopted to adopt cylindroid roller bearing all can improve blanking effect further when roller bearing 7 is installed.
Beneficial effect of the present invention: automatically can regulate blanking velocity, prevents hopper from blocking, and ensures tea leaf quality.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
