Description

Liquid filling machine

Technical Field

The utility model relates to a liquid filling machine.

Background

In the liquid packing production process, a liquid filling machine is usually needed to be used, and automatic filling is realized to improve the production efficiency. The liquid level equal filling machine disclosed in the chinese patent 2017201753835 can realize the automation of liquid filling, and simultaneously, the material higher than the set page is pumped back to the material box through a feeding pipe and a back-pumping pipe, so as to realize the effect that the liquid level of the liquid in all bottles 101 is level and level, and make the liquid in the bottles 101 equal; however, in the case where the liquid filled in the bottle 101 is pumped out through the suction pipe and sent back to the tank, the foam is not sucked away in the case of high-level filling, so that the foam generated in the bottle 101 overflows and cannot be filled normally, as shown in fig. 1 (the tank, the suction pipe and the feeding pipe are omitted).

In order to solve the above problems, on the basis of the above-mentioned chinese patent 2017201753835, the filling head is made into a liftable structure, that is, after the filling is started, the filling rod on the filling head is directly lifted to the bottom of the bottle, and with the rise of the liquid level in the bottle, the filling rod is gradually lifted until the filling is completed, and then the filling rod is lifted to the upper part of the bottle mouth, and the cycle is repeated until all the filling work is completed. On above-mentioned structure basis, however, adjust the liquid flow in the filling head and mainly rely on the manual control valve on the discharging pipe, and manual control valve needs the manual regulation aperture, will have great error, lead to the liquid flow in every filling head different, finally lead to the not parallel and level of liquid level of filling liquid in the bottle, for the liquid level basic parallel and level of filling liquid in guaranteeing the bottle, need the artifical repeated multiple adjusting valve body's aperture, then can lead to production efficiency very low, consuming time power.

Disclosure of Invention

The utility model aims at providing a produce the liquid filling machine of foam and the filling liquid level parallel and level of effectively guaranteeing the bottle when avoiding the filling.

A liquid filling machine, including storing the workbin of treating liquid of irritating, be provided with a plurality of discharging pipes at workbin bottom interval, all be provided with manual regulating valve on every discharging pipe, below at every manual regulating valve and all be provided with pneumatic control valve or flow valve on the discharging pipe, it is provided with the filling head of a plurality of liftable still to go back the one-to-one in the below of all discharging pipes, every filling is overhead all to be provided with the filling pole, pass through the hose intercommunication between every discharging pipe and the corresponding filling head, when the filling head descends to the extreme low position, the filling pole stretches into the bottom in the corresponding bottle, when the filling head rises to the extreme high position, the filling pole rises to on the corresponding bottleneck.

A liquid filling machine, when needing the filling, open manual control valve to the biggest to and set up the aperture of pneumatic control valve or the flow that passes through of flow valve, through external inlet pipe on the workbin, can incessantly pour into filling liquid into the workbin at the filling in-process, thereby make in the workbin and filling head between form pressure differential, thereby realize continuous filling. The filling head can be lifted, so that all filling rods can extend into the bottom of a bottle along with the descending of the filling head during filling, the filling head rises along with the rising of the liquid level, the filling rods also gradually rise until the filling is finished, and the filling rods rise above the bottle mouth again, so that the bottle conveying of the filled bottle is prevented from being hindered; and owing to all be provided with pneumatic control valve or flow valve in the below of every manual control valve and on the discharging pipe, operating personnel can directly set up pneumatic control valve's aperture or flow valve's flow on the control unit, thereby the control unit can directly control the aperture of each pneumatic control valve and the flow that passes through of each flow valve, so that the liquid filling volume in the bottle is unanimous, guarantee the liquid level parallel and level of the canned liquid in all bottles, avoid the manual work to adjust the liquid level in the pumpback pipe in order to control the bottle repeatedly, time saving and labor saving, high production efficiency. Through the dual control of manual governing valve and pneumatic control valve or flow valve, can effectively avoid the liquid in the feed box to flow out through the valve after the filling finishes, avoid the weeping.

Detailed Description

The utility model provides a liquid filling machine, as shown in figure 2, including storing workbin 1 of treating liquid of irritating, be provided with a plurality of discharging pipes 2 in workbin 1 bottom interval, all be provided with manual control valve 3 on every discharging pipe 2, all be provided with pneumatic control valve 4 or flow valve in the below of every manual control valve 3 and on discharging pipe 2, it is provided with the filling head 5 of a plurality of liftable still to correspond one-to-one in the below of all discharging pipes 2, all be provided with filling pole 6 on every filling head 5, through hose 7 intercommunication between every discharging pipe 2 and the corresponding filling head 5, when filling head 5 descends to the extreme lower position, filling pole 6 stretches into the bottom in the corresponding bottle 8, when filling head 5 rises to the extreme lower position, filling pole 6 rises to on the corresponding bottleneck. When the filling is needed, the manual regulating valve 3 is opened to the maximum, the opening degree of the pneumatic regulating valve 4 or the flow passing rate of the flow valve are set, the filling liquid can be injected into the material box 1 continuously in the filling process through the feeding pipe 9 externally connected to the material box 1, and therefore pressure difference is formed between the material box 1 and the filling head 5, and continuous filling is achieved. The filling head 5 can be lifted, so that all the filling rods 6 can extend to the bottom of the bottle 8 along with the descending of the filling head 5 during filling, the filling head 5 ascends along with the ascending of the liquid level, the filling rods 6 also ascend gradually until the filling is finished, and the filling rods 6 ascend to the upper part of the bottle mouth again to avoid the conveying of the filled bottle 8; and because below at every manual regulation valve 3 and all be provided with pneumatic control valve 4 or flow valve on discharging pipe 2, operating personnel can directly set up pneumatic control valve 4's aperture or flow valve's flow on the control unit, thereby the control unit can direct control each pneumatic control valve's aperture and each flow valve pass through the flow, so that the liquid filling volume in the bottle 8 is unanimous, guarantee the liquid level parallel and level of the canned liquid in all bottles 8, avoid the manual work to adjust the liquid level in the pumpback pipe in order to control bottle 8 repeatedly, time saving and labor saving, high production efficiency. Through the dual control of manual control valve 3 and pneumatic control valve 4 or flow valve, can effectively avoid the liquid in workbin 1 to flow out through the valve after the filling finishes, avoid the weeping.
