The filling apparatus of weighing
Technical field
The utility model relates to a kind of filling apparatus, especially relates to a kind of to the isostructural improvement of the filling apparatus of weighing.
Background technology
Existing bottle placer is to store charging basket together to turn round with filling tube, and filling bottle is required tight, the height of its filling bottle must be consistent, bottleneck seals with packing seal with the filling tube joint during can, producing gas leak phenomenon when bottleneck has small cut makes quantitatively out of control, this structure not only makes troubles to can, and its complex structure also seems heavy.Chinese patent discloses a kind of low vacuum filling machine (application number: 02223184.6), it comprises rotating mechanism, the bottle transmission device, in body upper liquid reserve tank is arranged, be provided with spool in the liquid reserve tank bottom, spool can move up and down in flange, has one of symmetry to list fluid through-hole on the spool, the line of centers that goes out fluid through-hole tangentially is inclined upwardly, and makes liquid stream can form eddy flow; Be arranged with filling tube at spool, the height of filling tube can up-down adjustment.But the filling apparatus of this structure causes liquid to be polluted easily because spool is located at liquid reserve tank inside; Filling tube begins to be exposed in the air, stretch into bottle then after, also filling liquid is polluted; Because filling accuracy is controlled in the lifting by spool, causes the can error bigger, measures inaccurate.
Summary of the invention
The utility model mainly is to solve existing in prior technology liquid to be polluted easily, and the can error is bigger, measures the technical matters of inaccurate grade.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
The filling apparatus of weighing of the present utility model, comprise Connection Block, be located at the material cylinder on the Connection Block, Connection Block is provided with the discharging mouth, the Connection Block bottom is provided with protects the bottle seat, described Connection Block inside is provided with blocked shot, and the one end is connected with actuating device, the termination tapering of the other end be located at discharging mouth in-to-in adapter sleeve tapering and be complementary; The described bottle seat bottom of protecting is provided with LOAD CELLS, and it is connected with the actuating device that blocked shot one end is provided with.Blocked shot is by up-and-down movement, and controlling liquid flows out from the discharging mouth; Blocked shot termination tapering be located at discharging mouth in-to-in adapter sleeve tapering and be complementary, the flow that can controlling liquid flows out from the discharging mouth, thus reach metering accurately; LOAD CELLS can be measured the weight of bottle after by can, sends out signal then to actuating device, thereby the motion of control blocked shot realizes accurate re-filling.
As preferably, described material cylinder is by opening through hole and the Connection Block internal connection on Connection Block.The material cylinder independently is provided with, and avoids the Connection Block outside that the liquid in the material cylinder is polluted.
As preferably, described actuating device is a cylinder.The shared volume of cylinder is less, be convenient to install, and driving force is bigger.
As preferably, discharging mouth lower end is provided with net-filter assembly.Net-filter assembly can be avoided liquid to drip to and protect on the bottle seat so that after the can end, drop can be stayed on the discharging mouth, pollutes and wastes.
As preferably, be provided with orienting sleeve between Connection Block and the blocked shot.Because blocked shot length is longer, orienting sleeve is set controls blocked shot and make vertical up and down movement.
As preferably, be connected with flange between Connection Block and the cylinder.Connecting with flange can be so that assembling be simpler, but also bolt together between Connection Block and the cylinder.
Therefore, the utlity model has liquid and be not vulnerable to pollute, the can error is less, and accurate measurement is rational in infrastructure, etc. characteristics.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the filling apparatus of weighing of this example, as Fig. 1, a Connection Block 1 is arranged, material cylinder 2 is by opening through hole and the Connection Block internal connection at Connection Block 1 upper side edge.Connection Block 1 inside is provided with blocked shot 5, and the lower end is provided with discharging mouth 3, and discharging mouth 3 bottoms are provided with protects bottle seat 4, protects bottle seat bottom and is provided with LOAD CELLS 7, and it is connected with the actuating device cylinder 8 that blocked shot 5 one ends are provided with.One end of blocked shot 5 is connected with actuating device cylinder 8, the termination tapering of the other end be located at discharging mouth 3 in-to-in adapter sleeves 6 taperings and be complementary; Discharging mouth 3 lower ends are provided with net-filter assembly 9.Be provided with orienting sleeve 10 between Connection Block 1 and the blocked shot 5.Be connected with flange 11 between Connection Block 1 and the cylinder 8.
During use, will be placed on by the bottle 12 of can and protect on the bottle seat 4, fix; Open the valve of material cylinder 2, make liquid enter Connection Block inside; Start cylinder 8, cylinder drives blocked shot 5 upward movements, and the orifice flow of liquid from adapter sleeve 6 gone into bottle 12; LOAD CELLS 7 is started working, and when bottle 12 is filled to a certain degree, LOAD CELLS is dealt into weight signal on the cylinder 8, is moved downward by cylinder control blocked shot 5, makes the gap smaller of blocked shot termination and adapter sleeve 6, thereby reaches the low discharge can; After re-filling was finished, LOAD CELLS 7 was dealt into cylinder 8 with signal, thereby control blocked shot 5 continues to move downward the hole in blocking adapter sleeve 6, and can is finished.
