Abstract

The utility model relates to an automatic feed and discharge structure of a packaging weigher, which has a double-open type discharge door which is transversely pushed by a cylinder to rotate around a connecting shaft and to be opened or closed. Both ends of a connecting rod respectively ensure the synchronous movement of the discharge door. Both ends of a limited plate are respectively hinged with a measuring hopper body and a connecting piece which is connected with an outer shell through a regulating block. Because the limited plate of the utility model limits the measuring hopper body to swing in feeding process, the double-open door structure fundamentally eliminates transverse component force of materials to the measuring hopper body in discharging process. Numerical values measured by a sensor are stable and reliable. The packaging weigher can rapidly restore zero position after finished discharging; the measuring precision and speed is enhanced.

Description

The measurement structure of packing scale

The utility model belongs to the measurement structure of packing scale.

The measurement structure of current packaging scale, the disclosed measurement structure of CN2212782Y " ration package scale " for example, system controls the discharge door blowing of single open-door formula with cylinder, symmetrical in addition heavy burder bucket does not overcome the technical measures of teeter, thereby this kind structure exists following defective: the one, and all packing scales material in fill process is difficult to placed in the middle, thereby the lateral impact forces that the metering bucket body is produced is difficult to elimination, the 2nd, emptying door is a single open-door in the blowing process, can produce transverse component to the single open-door that tilts during blowing, it is moving to make the metering bucket body make movable pendulum in the blowing process, to need the long period just can get back to stable for bucket body behind blowing, influences the measuring accuracy and the efficient of packing scale.

The purpose of this utility model is to provide a kind of precision and higher packing scale measurement structure of efficient of metering.

The technical scheme that realizes above-mentioned purpose is: a kind of measurement structure of packing scale, have shell, sensor, oscillating bearing, suspension rod, metering bucket body, cylinder and emptying door, and it is characterized in that: emptying door is the double-open type emptying door; And the pivoted arm of emptying door is rotationally connected by coupling shaft and metering bucket body; The two ends of one cylinder are hinged with the upper arm of pivoted arm of two fan emptying doors respectively; The underarm of one end of one connecting rod and the pivoted arm of an emptying door is hinged, and the upper arm of the pivoted arm of the other end and another emptying door is hinged; The two ends of limiting plate are hinged with metering bucket body and web member respectively, and web member is by regulating block and shell load.

After the utility model adopts technique scheme, because limiting plate has limited the swing of metering bucket body in fill process, make the numerical stability of sensor measurement reliable, thereby improved the precision of metering greatly, again because double door and laterally promote again to guarantee that by connecting rod the structure of double door synchronization action makes in the blowing process material that the transverse component of metering bucket body is eliminated substantially by cylinder, limiting plate also makes the metering bucket body can settle out rapidly after blowing finishes in addition, reduce the needed time of recovery zero-bit, thereby improved the speed of metering greatly.

The embodiment that provides below in conjunction with accompanying drawing is further described specifically structure of the present utility model.

Fig. 1 is the measurement structure of a kind of packing scale of the present utility model.

Fig. 2 is that the B of Fig. 1 is to view.

Fig. 3 is the A-A cut-open view of Fig. 2.

Fig. 4 is the C-C revolved sectional view of Fig. 1.

As Fig. 1, shown in 2, the measurement structure of a kind of packing scale of the present utility model, has shell (5), sensor (1), oscillating bearing (2), suspension rod (3), metering bucket body (4), cylinder (6) and emptying door, emptying door is double-open type emptying door (7), and the pivoted arm (7-1) on the emptying door (7) is rotationally connected by coupling shaft (10) and metering bucket body (4), for example pivoted arm (7-1) is hinged on measure the coupling shaft (10) that bucket body (4) fixedlys connected on, the two ends of one cylinder (6) are hinged with the upper arm of pivoted arm (7-1) of two fan emptying doors (7) respectively, the underarm of one end of one connecting rod (8) and an emptying door (7) is hinged, the upper arm of the other end and another emptying door (7) is hinged, the two ends of limiting plate (14) are hinged with metering bucket body (4) and web member (15) respectively, and web member (15) is by regulating block (11) and shell (5) load.Cylinder (6) can laterally promote the upper arm of pivoted arm (7-1) and make emptying door (7) open or close around coupling shaft (10) rotation.The effect of connecting rod (8) is that two fan emptying doors (7) can be opened and closed when opening and closing synchronously, to reduce in the blowing process material to the horizontal force of emptying door (7).Limiting plate (14) will be adjusted to level, to avoid that metering bucket body (4) is produced transverse component.Web member (15) can directly be threaded with regulating block (11) by the screw rod of afterbody or rely on nut screwing clamping, regulating block (11) can directly be fixedly mounted on the housing (5), but preferably be installed on the housing (5) by regulating bolt (13) and nut (12), like this, web member (15) is by regulating block (11) and regulate bolt (13) and nut (12) is installed on the housing (5), both can regulate in the horizontal direction, can regulate in vertical direction, so that limiting plate (14) both installed level, horizontal direction does not exist tensile force or force of compression when steady state (SS) again, thereby guaranteed that limiting plate (14) does not only produce transverse component in the horizontal direction to metering bucket body (4), and metering bucket body (4) has been limited its swing in the horizontal direction.

As shown in Figure 3, metering bucket body (4) has bucket tube (4-1), cross-arm (4-2) and montant (4-3).Bucket tube (4-1) and cross-arm (4-2) welding, cross-arm (4-2) is connected with screw with montant (4-3), also can adopt other fixedly connected mode, and they all belong to parts of metering bucket body (4).Limiting plate (14) is then hinged with the montant (4-3) of metering bucket body (4), also can be otherwise hinged with metering bucket body (4).

Shown in Fig. 2,4, bucket tube (4-1) lower edge (9) of metering bucket body (4) is located notch and is embedded with the seal (16) that can contact with emptying door (7), sealing part (16) can adopt rubber strip, also can adopt other material, to prevent the leakage of material in the metering process.

As shown in Figure 1, 2, sensor (1) is fixedly mounted on the housing (5), and oscillating bearing (2) is fixedly connected on the horizontal external part of sensor (1), fixedlys connected with oscillating bearing (2) in the upper end of suspension rod (3), fixedlys connected with metering bucket body (4) in the lower end.This mounting means of sensor (1) can improve the measuring accuracy of sensor.
