DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The utility model provides a liquid separation device and a blowing, filling and sealing integrated machine, which can stabilize the pressure in the liquid separation device during filling, avoid fluctuations in the filling volume, and improve the filling accuracy of the product.

[0024] Please refer to Figure 1 and Figure 2 The utility model provides a liquid separation device including a liquid separation component 10 and a pressure maintaining component 20.

[0025] A liquid storage chamber 11 is formed inside the liquid separation component 10 for storing the medicinal liquid to be filled; a liquid inlet 12 and a liquid outlet 13 are also provided on the liquid separation component 10, and the liquid inlet 12 and the liquid outlet 13 are both connected to the liquid storage chamber 11, wherein the liquid inlet 12 is used for the medicinal liquid to enter the liquid storage chamber 11, and the liquid outlet 13 is used for the medicinal liquid to be discharged from the liquid storage chamber 11.

[0026] Please refer to Figure 1 and Figure 2 The liquid inlet 12 is arranged at the top of the side of the liquid separation member 10, and the liquid to be filled enters the liquid storage chamber 11 through the liquid inlet 12; the liquid outlet 13 is arranged at the bottom of the liquid separation member 10, and the liquid outlet 13 is a straight channel. When the liquid is filled, it is discharged from the liquid storage chamber 11 through the liquid outlet 13.

[0027] In this embodiment, there are multiple liquid outlet holes 13, and the liquid outlet holes 13 are evenly distributed at the bottom of the liquid separation member 10. The multiple liquid outlet holes 13 can be distributed in a circular array or a rectangular array, which is not specifically limited.

[0028] The liquid separating member 10 is also provided with a connecting hole 14 . The connecting hole 14 is opened at the top of the liquid separating member 10 , and the connecting hole 14 is communicated with the liquid storage chamber 11 .

[0029] Please refer to Figure 1 and Figure 2 The pressure-maintaining member 20 is arranged at the connecting hole 14 of the liquid-separating member 10. The pressure-maintaining member 20 includes an outer shell 21, an inner core 22 and a driving device (not shown). The outer shell 21 is fixedly arranged on the liquid-separating member 10. The outer shell 21 is provided with a through hole 211 penetrating the outer shell 21. The through hole 211 is communicated with the connecting hole 14 on the liquid-separating member 10; the inner core 22 is arranged in the through hole 211, and the inner core 22 is slidably connected to the outer shell 21, and the inner core 22 can slide along the through hole 211; the driving device is connected to the inner core 22, and the driving device is used to drive the inner core 22 to slide axially along the through hole 211, thereby changing the pressure in the liquid storage chamber 11.

[0030] In this embodiment, the driving device is specifically a driving motor that outputs linear motion, and the driving motor drives the inner core 22 to perform linear motion and slide along the through hole 211 in the outer shell 21; the driving motor is a forward and reverse motor, and as the driving motor rotates forward and reverse, it can drive the inner core 22 to perform reciprocating motion along a straight line in the through hole 211.

[0031] It should be understood that the outer shell 21 and the liquid separation member 10 are well sealed, and the inner core 22 and the outer shell 21 are also well sealed. When the driving device drives the inner core 22 to slide along the through hole 211, the inner core 22 and the outer shell 21 maintain a good sealing state without any air leakage.

[0032] In some of the embodiments, a sealing ring (not shown) is provided on the inner core 22 , and the sealing ring is sleeved on the inner core 22 , so that the inner core 22 maintains a good sealing state with the liquid separation member 10 through the sealing ring.

[0033] In some of the embodiments, a pressure sensor (not shown) is installed in the liquid storage chamber 11 for measuring the air pressure in the liquid storage chamber 11, so as to intuitively reflect the pressure in the liquid storage chamber 11 during filling.

[0034] The utility model also provides a blow-fill-seal integrated machine, which comprises a liquid separation device provided by any of the above embodiments, and the liquid separation device is installed at the end position of the medicine liquid pipeline in the blow-fill-seal integrated machine.

[0035] The pressure-maintaining member 20 provided on the liquid-separating member 10 can achieve a stable pressure inside the liquid-separating device. The liquid medicine is transported into the liquid storage chamber 11 through the liquid inlet 12 on the liquid-separating member 10 through the pipeline, and the liquid medicine in the liquid storage chamber 11 is discharged from the liquid outlet 13 to complete the filling. As the liquid medicine is discharged from the liquid outlet 13, the pressure of the liquid storage chamber 11 inside the liquid-separating member 10 in the liquid-separating device changes, and the driving device drives the inner core 22 to move in a straight line in the through hole 211. As the position of the inner core 22 changes, the pressure in the liquid storage chamber 11 changes again.

[0036] As the medicine liquid is discharged from the liquid outlet 13, the air pressure in the liquid storage chamber 11 of the liquid separation device decreases, and the driving device drives the inner core 22 to move toward the liquid storage chamber 11, so that the air pressure in the liquid storage chamber 11 increases, thereby stabilizing the pressure in the liquid separation device during filling, avoiding fluctuations in the filling amount, and improving the filling accuracy of the product.

[0037] In the liquid dispensing device provided by the present invention, the pressure-maintaining member 20 is arranged at the connection hole 14 of the liquid dispensing member 10, and the inner core 22 is slidably arranged in the through hole 211. As the inner core 22 moves along the through hole 211, the pressure in the liquid storage chamber 11 changes, so that the pressure in the liquid dispensing device can be stabilized during filling, avoiding fluctuations in the filling volume and improving the filling accuracy of the product; when the pressure fluctuates greatly or when filling a large amount of products, the pressure can also be kept stable. Since the blow-fill-seal integrated machine includes all the technical features of the liquid dispensing device, the blow-fill-seal integrated machine can produce the same technical effects as the liquid dispensing device.

[0038] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0039] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the utility model.
