Description

Technical Field

[0001] This utility model relates to the field of liquid filling device technology, and in particular to a filling mechanism and filling equipment. Background Technology

[0002] Currently, liquid cosmetics production typically employs liquid filling equipment for bottling, where a specific volume of liquid is directly injected into the bottle through the filling nozzle. However, existing liquid filling equipment often experiences backflow of external gas through the filling nozzle after a single filling, resulting in gas mixing into the liquid to be filled. Therefore, even with the same single-fill flow rate setting at the filling nozzle, the actual output liquid volume is often lower than the predetermined value due to the presence of mixed gas, thus affecting the filling accuracy of the liquid filling equipment. Utility Model Content

The valve core is elastically connected to the inner wall of the unidirectional flow channel through an elastic element.

[0009] The valve core moves in a direction away from the first channel, which can drive the elastic element to deform and be spaced apart from the inner wall of the second channel so that the first channel and the second channel are connected. The deformed elastic element can drive the valve core to move in a direction close to the first channel so that the valve core abuts against the connecting surface, thereby separating the first channel and the second channel.

[0010] In one embodiment, the valve core and the connecting surface are flexibly connected.

[0011] In one embodiment, the inner wall of the unidirectional flow channel is provided with a first rubber lining layer, and / or, the outer surface of the valve core is provided with a second rubber lining layer.

[0017] The housing has a material passage that connects the inlet to the outlet, and a flow valve is provided in the material passage.

[0018] In one embodiment, the filling mechanism further includes a body and a mounting frame assembly, the mounting frame assembly comprising:

[0026] This utility model provides a filling mechanism and filling equipment, which have the following advantages compared with the prior art:

[0027] The filling mechanism of this utility model incorporates a check valve assembly between the feed pipe of the feeding component and the filling pipe of the filling component. This check valve assembly has a unidirectional flow channel allowing liquid to flow only from the outlet end of the feed pipe to the feed end of the filling component. This design prevents air from flowing back into the feed pipe through the check valve assembly, ensuring precise quantitative delivery of liquid from the feed pipe to the filling component.

Detailed Implementation

[0035] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0036] It should be understood that the terms "before" and "after" are used in this utility model to describe various types of information, but these terms should not be limited to them. These terms are only used to distinguish information of the same type from each other. For example, "before" information can also be called "after" information, and "after" information can also be called "before" information, without departing from the scope of this utility model.

[0037] like Figures 1 to 6As shown, a filling mechanism 100 according to an embodiment of the present invention includes a feeding assembly 10, a filling assembly 20, and a check valve assembly 30. The feeding assembly 10 includes a feeding module 11 and a feeding pipe 12. One end of the feeding pipe 12 is connected to the feeding module 11, and the other end forms a discharge end. The feeding module 11 is used to deliver liquid into the feeding pipe 12. The filling assembly 20 has a filling pipe 21. One end of the filling pipe 21 forms a feeding end connected to the feeding pipe 12, and the other end is connected to the filling nozzle 22 of the filling assembly 20. 1. A connection is established to allow liquid in the filling pipe 21 to be poured out through the filling nozzle 221; the check valve assembly 30 includes a valve body 31 and a valve core 32. The valve body 31 is connected between the discharge end and the inlet end. A one-way flow channel 311 is provided through the valve body 31. The valve core 32 is provided in the one-way flow channel 311 in an openable and closable manner. The valve core 32 can be tightly fitted with the inner wall of the one-way flow channel 311 to close the one-way flow channel 311, and can be spaced from the inner wall of the one-way flow channel 311 when the liquid flows from the discharge end to the inlet end to open the one-way flow channel 311.

[0038] In some embodiments, the filling assembly 20 includes a filling head 22 with a filling nozzle 221. Liquid entering the filling pipe 21 through the check valve may be drawn into the filling cavity of the filling head 22 of the filling assembly 20 and then discharged outward through the filling nozzle 221. Of course, liquid entering the filling pipe 21 through the check valve may also flow into the filling head 22 under the action of gravity. Specific implementations can be set according to actual needs and are not limited here.

[0039] The filling mechanism 100 of this utility model embodiment provides a check valve assembly 30 between the feed pipe 12 of the feed assembly 10 and the filling pipe 21 of the filling assembly 20. The check valve assembly 30 has a unidirectional flow channel 311 that allows liquid to flow only from the outlet end of the feed pipe 12 to the feed end of the filling assembly 20. This configuration prevents air from flowing back into the feed pipe 12 through the check valve assembly 30, thereby ensuring quantitative delivery of liquid when the feed pipe 12 fills the filling assembly 20. The filling assembly 20 can then inject all the received liquid into the bottle, achieving precise quantitative filling and improving the filling accuracy of the liquid filling device.

[0040] like Figure 2 and Figure 3As shown, the unidirectional flow channel 311 of this utility model embodiment includes a first channel 311a and a second channel 311b connected sequentially along its flow direction. A connecting surface is formed at one end of the second channel 311b facing the first channel 311a. A valve core 32 is disposed in the second channel 311b and is movably disposed along the extension direction of the second channel 311b. It is elastically connected to the inner wall of the unidirectional flow channel 311 through an elastic member 33. The valve core 32, which moves away from the first channel 311a, drives the elastic member 33 to deform and is spaced apart from the inner wall of the second channel 311b, so that liquid flows from the first channel 311a to the second channel 311b. The elastic member 33 is used to drive the valve core 32 back to its initial position so that the valve core 32 abuts against the connecting surface and makes flexible contact with the connecting surface.

[0041] In one feasible embodiment, the inner wall of the unidirectional flow channel 311 of this utility model is provided with a first rubber lining layer; and / or, the outer surface of the valve core 32 is provided with a second rubber lining layer. The first and second rubber lining layers can be, but are not limited to, made of flexible materials such as rubber. This arrangement allows for flexible contact between the valve core 32 and the connecting surface, achieving better check valve sealing and reducing wear between the valve body 31 and the valve core 32.

[0042] like Figure 2 and Figure 3 As shown, in this embodiment of the invention, the valve body 31 has connecting joints 34 at both ends. The ends of the two connecting joints 34 facing the valve body 31 are respectively connected to the first channel 311a and the second channel 311b, and the ends of the two connecting joints 34 away from the valve body 31 are respectively inserted into the discharge end and the feed end. It can be understood that by providing connecting joints 34 at both ends of the valve body 31, the check valve assembly 30 can be quickly and easily connected to the filling pipe 21 and the feed pipe 12 by plugging and unplugging, which is beneficial to improving the ease of assembly and disassembly of the filling mechanism 100.

[0043] like Figure 3 As shown, in one feasible embodiment, the connecting joint 34 of this utility model includes a straight pipe portion 341 and two protrusions 342. The straight pipe portion 341 has an internally hollow tube structure and communicates with a one-way flow channel 311. The protrusions 342 are disposed on the outer wall of the straight pipe portion 341 and are arranged around the circumference of the straight pipe portion 341. The two protrusions 342 are arranged along the extending direction of the straight pipe portion 341, and the outer diameter of the protrusions 342 gradually decreases in the direction away from the valve body 31. This arrangement helps to ensure the sealing performance between the connecting joint 34 and its inserted pipe.

[0044] Of course, the technical solution of this utility model is not limited to this. In other embodiments, the straight pipe portion 341 of the connecting joint 34 may also be provided with three or more protrusions 342, thereby achieving multiple seals between the connecting joint 34 and its inserted pipe. Specific implementation methods can be set according to actual needs and are not limited here.

[0045] like Figure 6 As shown, the feeding module 11 of this embodiment includes a base 111, with an inlet and an outlet at its top and bottom ends, respectively. The inlet and outlet are connected to a storage device and a feeding pipe 12, respectively. A material passage 111a is formed inside the base 111, connecting the inlet to the outlet, and a flow valve is provided in the material passage 111a. With this configuration, the flow valve can achieve quantitative transmission of liquid by the feeding module 11. Furthermore, in some embodiments, a flow meter can also be provided at the material passage 111a or the feeding pipe 12 of the feeding module 11 to monitor the liquid delivery of the feeding assembly 10, thereby helping to ensure the filling accuracy of the filling mechanism 100.

[0046] like Figures 1 to 2 as well as Figure 5 As shown, the filling assembly 20 of this utility model embodiment includes a filling head 22 and a cylinder 23. The filling head 22 is provided with a filling cavity, and a filling nozzle 221 is provided at the bottom of the filling cavity. One end of the filling pipe 21 is provided on one side of the filling head 22 and communicates with the filling cavity. A piston is movably provided in the filling cavity. The cylinder 23 is provided at the end of the filling head 22 away from the filling nozzle 221 and is connected to the piston for transmission. It is used to drive the piston to move along the extension direction of the filling cavity so that the filling cavity is connected to or disconnected from the filling pipe 21.

[0047] like Figure 5 As shown, the filling mechanism 100 of this utility model embodiment also includes a body 40 and a mounting frame assembly 50. The mounting frame assembly 50 includes a first mounting part 51 and a second mounting part 52. The first mounting part 51 is disposed on the body 40 and has a first mounting rod 511 extending in a vertical direction. The second mounting part 52 includes a connecting block 521 and a second mounting rod 522. The connecting block 521 is provided with a connecting hole 521a for the first mounting rod 511 to pass through. One end of the second mounting rod 522 is disposed on the outside of the connecting block 521, and the other end extends in a horizontal direction and is connected to the filling assembly 20.

[0048] In some embodiments, the body 40 has an accommodating space to serve as the mounting base for functional modules such as the control module; a control panel may also be formed on the front side of the body 40 so that the user can control the working status of the filling mechanism 100 through the control panel.

[0049] like Figures 1 to 2As shown, the filling mechanism 100 of this embodiment of the present invention also includes a fixing member 60, which is disposed on the body 40. A protrusion 61 is provided on the side of the fixing member 60 away from the body 40, and a fixing hole 611 is provided through the protrusion 61 for the filling pipe 21 to pass through. With this arrangement, the filling pipe 21 can be fixed by the fixing member 60, which helps to improve the positional stability of the filling pipe 21.

[0050] This utility model also proposes a filling device, which includes a filling mechanism 100. The specific structure of the filling mechanism 100 is as described in the above embodiments. Since this filling device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
