Abstract
The utility model discloses a hopper door opening mechanism. The hopper door opening mechanism comprises a hopper body, a hopper door connected with the inner side of the hopper body through a hinge, a crankshaft component, a lever and a connecting rod, wherein one end of the connecting rod is connected with the hopper door through a hinge, the other end of the connecting rod is connected with a free end on the outer side of the lever through a hinge, and a free end of the crankshaft component is connected with a free end on the inner side of the lever. The hopper body is more stable during the hopper door opening process, so as to effectively guarantee the weighing accuracy of a hopper; and the hopper door opening mechanism has the advantages of simple structure and convenience in operation, and can meet the production requirements.
Description
Technical field
The utility model relates to the mechanical packaging technical field, is specifically related to a kind of hopper door-opening mechanism.
Background technology
Hopper is the common components in the bull combination balance, and especially in automatic packing system, hopper is the critical component of decision packing effect.
Existing bull combination balance includes a bucket body with hopper, and hinge is connected bucket hopper door composition on one's body, side at hopper door, one door-opening mechanism is installed, whole hopper is installed on the bull combination balance, require door-opening mechanism can in time open or close hopper door, though existing door-opening mechanism all can satisfy this production requirement, but, when existing hopper is opened or be closed at hopper door, can produce the bucket body and reverse, the bucket that makes is vibrations down on one's body, directly have influence on the function of weighing of bucket body thus, final influence packing effect.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of hopper door-opening mechanism, under the prerequisite that satisfies the basic production requirement, makes hopper have advantages of higher stability.
For achieving the above object, the utility model adopts following technical scheme:
The hopper door-opening mechanism, comprise that bucket body and hinge are connected the hopper door of described bucket body inboard, also include a crankshaft group, lever and a connecting rod, one end of described connecting rod is connected with described hopper door hinge, the other end is connected with the outside free end hinge of described lever, and the free end of described crankshaft group is connected in the inboard free end of described lever.
This hopper door-opening mechanism also includes one described bucket body is connected connecting assembly on the bull combination balance, described crankshaft group comprises rocking arm that is installed on the described connecting assembly and the pivoted arm that rotates with described synchronous rocker, and described pivoted arm is connected in the inboard free end of described lever.
The described bucket c-shaped extension arm that extends internally on one's body, described extension arm is provided with one and mounts bar, described connecting assembly be provided with one with the described groove that mounts that mounts the bar coupling.
The fulcrum of described connecting rod is positioned at described extension arm bottom.
Described lever is V-shaped.
The beneficial effects of the utility model are:
1, during hopper opened the door process, its bucket body had advantages of higher stability, can effectively guarantee the accuracy rate that hopper is weighed;
2, simple in structure, easy to operate, can satisfy production requirement.
Description of drawings
Fig. 1 is the structural representation of a kind of hopper door-opening mechanism of the utility model, and describes its a kind of mode of operation;
Fig. 2 is the another kind of working state schematic representation of hopper door-opening mechanism shown in Figure 1.
The specific embodiment
Below, in conjunction with the accompanying drawings and the specific embodiment, the utility model is further described:
As shown in Figure 1, be a kind of hopper door-opening mechanism of the present utility model, it comprises hopper 1, connecting assembly 2, captives joint with bull combination balance 3 in connecting assembly 2 inboards, and hopper 1 then is installed in the outside of connecting assembly 2.Hopper 1 comprises the extension arm 13 that struggles against body 11, hopper door 12 and C shape, hopper door 12 hinges are connected the inboard of bucket body 11, can rotate with respect to bucket body 11, hang the inboard that arm 13 welded or be shaped in bucket body 11, be connected with a horizontal bar 14 that mounts thereon, cooresponding with it, be provided with one at the outer surface of connecting assembly 2 and mount groove 23, during installation, to mount bar 14 is inlaid in and mounts in the groove 23, realization hopper 1 is connected with connecting assembly 2, and thus hopper 1 is installed in the desired location of bull combination balance 3.
Connecting assembly 2 is provided with a rocking arm 21 and a pivoted arm 22; rocking arm 21 can rotate synchronously with pivoted arm 22; lever 24 is installed on above-mentioned extension arm 13; its fulcrum is positioned at the bottom that hangs arm 13; the inboard free end of lever 24 connects with pivoted arm 22; between its outside free end and the hopper door 12 connecting rod 25 is installed, connecting rod 25 is connected with lever 24 outside free ends and hopper door 12 hinges respectively.
Again as shown in Figure 1, under the initial condition, pivoted arm 21 and rocking arm 22 are positioned at upper, hopper door 12 closed conditions, rotate pivoted arm 21; rocking arm 22 rotates thereupon, the inboard free end that drives lever 24 upwards rotates, the outside free end pulling connecting rod 25 of lever 24; make hopper door 12 and turn to the inside and open gradually with respect to the body 11 that struggles against; as shown in Figure 2, and when pivoted arm 21, rocking arm 22 turn to when the next, hopper door 12 is opened fully.
In the above-mentioned process of opening the door, when pivoted arm 22 rotates, the inboard free end of pull lever 24, fulcrum to lever 24 produces downward application force, can produce a downward pressure to hanging arm 13 thus, then bucket body 1 be applied downward pressure, the rotation trend of body 1 generation of then avoiding struggling against with respect to connecting assembly 2, define the degree of freedom that bucket body 1 rotates, its accuracy rate of weighing is guaranteed.
Open the door for convenience, the inventor is processed into vee shape with above-mentioned lever 24, and its fulcrum is positioned at the flex point place, bottom of vee shape.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to technical scheme described above and design.
