[0001] This invention relates to the field of cosmetic production technology, and in particular to a binary aerosol filling mechanism. Background Technology
[0002] The aerosol filling production line includes filling, sealing and filling, weighing, water bath testing, coding, nozzle assembly and capping. During filling, the bottle moves to the bottom of the filling head, and then the filling head fills the bottle. Currently, multiple bottles are picked up at once, and then multiple filling heads fill the bottles. However, it is currently impossible to detect whether there is a bottle under the filling head, which leads to the phenomenon of filling even when there is no bottle, resulting in inaccurate filling and waste. Summary of the Invention
[0003] In view of this, embodiments of the present invention provide a binary aerosol liquid filling mechanism to avoid misfilling and save costs.
[0004] This invention discloses a binary aerosol filling mechanism, including a cylinder and a transition joint. One side of the transition joint is connected to a filling connector, the output end of the cylinder is connected to the transition joint, and the lower end of the transition joint is connected to the upper end of a filling valve body.

Fixing sleeve one is located at the upper end of fixing sleeve two. The pressure head includes an upper pressure head and a lower pressure head. The upper end of the upper pressure head is provided with cavity one, and the lower end of the upper pressure head is provided with cavity two. The diameter of cavity one is smaller than the diameter of cavity two. The lower end of the lower pressure head is provided with cavity three. The diameter of cavity three is larger than the diameter of cavity two. Fixing sleeve one is in contact with cavity one, and fixing sleeve two is in contact with cavity two.
[0006] Furthermore, spring two is installed at the bottom of the upper pressure head.
[0007] Furthermore, the upper inner side of the first fixing sleeve is provided with channel two and channel three, the inner side of the second fixing sleeve is provided with channel four, the locking sleeve is threadedly connected to channel two, the diameter of channel three is larger than the diameter of channel two, and the diameter of channel four is smaller than the diameter of channel two.
[0008] Furthermore, the filling ejector pin includes ejector rod one, ejector rod two, and ejector rod three. Ejector rod two connects ejector rod one and ejector rod three.

[0010] Furthermore, during filling, the top of the bottle neck is located in the cavity of the lower pressure head, and the guide sleeve in the middle of the bottle neck is located in the filling channel.
[0011] This invention is in a closed state before contacting the bottle body and cannot be filled. After the cylinder works, it must first contact the pressure head and use the spring to ensure that the bottle mouth is locked to prevent leakage during filling. The liquid will only be filled after the filling pin separates the sealing cap from the lower sealing seat, thus avoiding bottleless filling. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] As shown in the figure, this embodiment of the invention discloses a binary aerosol liquid filling mechanism, including a cylinder 18 and a transition joint 1. One side of the transition joint 1 is connected to a filling joint 21, and the output end of the cylinder 18 is connected to the transition joint 1. The lower end of the transition joint 1 is connected to the upper end of a filling valve body 2. A lower sealing seat 5 and a locking sleeve 8 are installed on the inner side of the lower end of the filling valve body 2. An outer fixing sleeve 9 is installed on the outside of the locking sleeve 8 and is located at the lower end of the filling valve body 2. A filling ejector pin 7 is installed inside the outer fixing sleeve 9. A cavity 201 is provided at the center of the filling valve body 2. A spring 17 passes through the upper end of the cavity 201. A spring 17 is installed at the middle of the lower end of the transition joint 1. The bottom of spring 17 is connected to the sealing cap 3. A sealing cap 4 is installed at the lower end of the sealing cap 3. A pin 6 is installed in the middle of the sealing cap 4, with its end located at the lower end of the sealing cap 4. The lower sealing seat 5 has a channel 501, and part of the sealing cap 4 is located in channel 501. The top of the filling pin 7 contacts the bottom of the sealing cap 4. The filling pin 7 passes through the middle of the locking sleeve 8 and the outer fixing sleeve 9. A pressure head 13 is provided on the outer side of the outer fixing sleeve 9. A spring 22 is provided between the upper end of the pressure head 13 and the transition joint 1. The spring 22 is wound around the outer ring of the filling valve body 2. The bottom of the filling pin 7 is located between the bottom of the outer fixing sleeve 9 and the bottom of the pressure head 13. In use, the bottle to be filled is moved beforehand to below the pressure head 13. During filling, cylinder 18 operates, causing transition joint 1 to move downwards. At this time, pressure head 13 connects to bottle mouth 14. Cylinder 18 continues to operate, and pressure head 13 is stopped from moving by bottle mouth 14. Spring 22 is compressed, and outer fixing sleeve 9 moves downwards relative to pressure head 13. Filling pin 7 continues to move downwards until the lower end of filling pin 7 connects to guide sleeve 15 in the middle of bottle mouth. Cylinder continues to operate, while filling pin 7 is stopped from moving by guide sleeve 15. In this way, filling pin 7 holds sealing cap 4 in place, while lower sealing seat 5 continues to move downwards. This separates sealing cap 4 from lower sealing seat 5, achieving conductivity. The liquid to be filled can then enter cavity 201 from filling joint 21, then into filling pin 7, and finally into guide sleeve 15, ultimately entering the bottle body to complete the filling process.
[0024] In one embodiment of the present invention, the outer fixing sleeve 9 includes a first fixing sleeve 91 and a second fixing sleeve 92. The outer diameter of the first fixing sleeve 91 is smaller than the outer diameter of the second fixing sleeve 92. The first fixing sleeve 91 is located at the upper end of the second fixing sleeve 92. The pressure head 13 includes an upper pressure head 131 and a lower pressure head 132. The upper end of the upper pressure head 131 is provided with a first cavity 1311, and the lower end of the upper pressure head is provided with a second cavity 1312. The diameter of the first cavity 1311 is smaller than the diameter of the second cavity 1312.

The first fixing sleeve 91 contacts the first cavity, and the second fixing sleeve contacts the second cavity. The outer fixing sleeve 9 can slide relative to the pressure head 13. The pressure head 13 can press down the top of the bottle, making the bottle stable during filling and preventing tilting during filling.
[0025] In one embodiment of the present invention, spring 22 is mounted on the bottom of the upper pressure head 131. During filling, spring 22 applies pressure to the pressure head.
[0026] In one embodiment of the present invention, the upper inner side of the fixing sleeve 1 91 is provided with channel 2 911 and channel 3 912, the inner side of the fixing sleeve 2 is provided with channel 4 921, the locking sleeve 8 is threadedly connected to channel 2, the diameter of channel 3 is larger than the diameter of channel 2, and the diameter of channel 4 is smaller than the diameter of channel 2.
[0027] In one embodiment of the present invention, the filling ejector pin 7 includes ejector rod 1 71, ejector rod 2 72 and ejector rod 3 73. Ejector rod 2 72 connects ejector rod 1 71 and ejector rod 3 73. The diameter of ejector rod 2 is greater than the diameter of ejector rod 3, and the diameter of ejector rod 3 is greater than the diameter of ejector rod 1. Ejector rod 1 71 passes through locking sleeve 8. The diameter of ejector rod 2 is greater than the diameter of channel 4. The height of ejector rod 2 is less than the height of channel 3. Ejector rod 3 passes through channel 4.
[0028] In one embodiment of the present invention, the filling ejector pin 7 is provided with three interconnected filling channels from top to bottom: a first filling channel 74, a second filling channel 75, and a third filling channel 76. The opening at the bottom of the third filling channel is larger than the opening at the top of the third filling channel. The liquid to be filled enters the bottle through the first filling channel 74, the second filling channel 75, and the third filling channel 76.
[0029] In one embodiment of the present invention, during filling, the top of the bottle mouth 14 is located at the cavity of the lower pressure head, and the guide sleeve 15 in the middle of the bottle mouth is located in the filling channel.
