Abstract
The utility model provides a driving mechanism of a feeding valve. The driving mechanism of the feeding valve comprises a feeding door fixedly connected with a door shaft and an installation block. One end of a connecting rod is hinged to the installation block, the other end of the connecting rod is hinged to one end of a single-lug air cylinder, the middle of the connecting rod is hinged to one end of a double-lug air cylinder, the other end of the single-lug air cylinder is hinged to the feeding door through a fixing cushion block, the other end of the double-lug air cylinder is hinged to one end of the connecting rod, and the other end of the connecting rod is fixedly connected with the door shaft. According to the driving mechanism of the feeding valve, a four-rod mechanism is adopted, through the successive stretch and retraction of the two air cylinders connected in parallel, the door shaft is driven by the connecting rod to rotate, so that the feeding door is opened fully, opened slightly and closed, the reliability of a device is improved, maintenance cost is reduced, and the production efficiency is improved.
Description
Technical field
The utility model belongs to weighing equipment technical field, especially relates to a kind of feed mechanism being applied on quantitative package machine or ration bulk scale.
Background technique
About the quantitative separating of material, ripe quantitative automatic packaging facilities at present, the automatically quantitative packing that completes one bag of material mainly completes by two steps: i.e. thick charging (enhancing productivity) and thin charging (assurance measuring accuracy) two steps.This kind equipment generally adopts the large valve of the thick charging of driven by servomotor and the minor valve of thin charging, and in high-efficiency and continuous operation, frequent instantaneous the reaching at a high speed of actuating motor, easily produces overload, and impact is produced, and even damages actuating motor.
Model utility content
The purpose of this utility model is to provide a kind of driving mechanism of feed valve, substitutes the actuating motor on existing equipment, improves equipment reliability, reduces maintenance cost, enhances productivity simultaneously.
The technical solution of the utility model: a kind of driving mechanism of feed valve, comprise the confession bin gate affixed with door-hinge, mounting blocks, wherein one end of connecting rod and mounting blocks are hinged, one end of the other end and monaural cylinder is hinged, and one end of intermediate portion and Double ear handle cylinder is hinged, and the other end of described monaural cylinder connects by fixing cushion block and feed door hinge, the other end of described Double ear handle cylinder and one end of connecting rod are hinged, and the other end and the door-hinge of described connecting rod are affixed.
Further, the hinged fixing cushion block of described and monaural cylinder is fixed in the curve bath on bin gate.
The utility model adopts four-bar mechanism principle, control system is stretched by the priority of controlling two cylinders in parallel, makes connecting rod drive door-hinge rotation, drives for bin gate displacement, the discharging mouth of pipe realized greatly fast open, littlely opened and close, realize thick charging and the thin charging of quantitative automatic packaging facilities.Adopt two cylinder in parallel, eliminated the overload problem of equipment, extended the working life of cylinder, improved equipment reliability, reduced maintenance cost, improved manufacturing efficiency simultaneously
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1-mounting blocks, 2-connecting rod, 3-monaural cylinder, 4-fixes cushion block, and 5-is for bin gate, 6-discharge nozzle, 7-door-hinge, 8-connecting rod, 9-Double ear handle cylinder, 10-curve bath.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of driving mechanism of feed valve, comprise the confession bin gate 5 affixed with door-hinge 7, mounting blocks 1, wherein one end of connecting rod 2 and mounting blocks 1 are hinged, and one end of the other end and monaural cylinder 3 is hinged, one end of intermediate portion and Double ear handle cylinder 9 is hinged, the other end of described monaural cylinder 3 is by fixing cushion block 4 with hinged for bin gate 5, and one end of the other end of described Double ear handle cylinder 9 and connecting rod 8 is hinged, and the other end of described connecting rod 8 and door-hinge 7 are affixed.Mounting blocks 1 is fixed on the support of equipment, two cylinders, connecting rod 2 and connecting rods 8 have formed fourbar linkage, and control system, by controlling the flexible of two cylinders in parallel, makes connecting rod 8 drive door-hinge 7 to rotate, drive for bin gate 5 displacements, make that discharge nozzle 6 carries out slightly, carefully discharging.
Further, fixing in the curve bath 10 on bin gate 5 with the hinged fixing cushion block of monaural cylinder 34.By regulating the position of fixing cushion block 4 in curve bath 10, can change quantitative automatic packaging facilities in the time of thin charging, the size of the discharging mouth of pipe, to adapt to different materials and different quantitative accuracies.
When work, control system control monaural cylinder 3 bounces back, and when Double ear handle cylinder 9 stretches out, connecting rod 8 drives door-hinge 7 to rotate, and makes to open greatly for bin gate 5, and quantitative automatic packaging facilities carries out thick charging; In the time reaching preset weight, when control system control Double ear handle cylinder 9 bounces back, connecting rod 8 drives door-hinge 7 to rotate, and makes to open for bin gate 5 is little, and quantitative automatic packaging facilities carries out thin charging; In the time reaching preset weight accuracy value, control system control monaural cylinder 3 stretches out, and when Double ear handle cylinder 9 bounces back, connecting rod 8 drives door-hinge 7 to rotate, and makes to close for bin gate 5.Wait enters next work cycle.
Certainly; the utility model also can have other various embodiments; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
