The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0022] The existing device has no blocking in the filling head, so dust and impurities are easily mixed in, which reduces the filling quality and requires manual cleaning, increasing costs and affecting production efficiency.

[0023] In view of this, a filling head of a filling machine is provided. Through the cooperation between the sealing plug, the first spring, the sliding rod, the positioning block, the limit block and the ring cylinder, the discharge pipe opening of the filling head can be quickly sealed, thereby solving the problem that the existing device is easy to float in dust and impurities due to the filling head not being blocked, thereby reducing the filling quality, requiring manual cleaning, increasing costs and affecting production efficiency.

[0024] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0025] Embodiment 1: Figure 1-4It can be seen that a filling head of a filling machine includes a tank body 1, an outer wall of the tank body 1 is provided with a base 3, one side of the outer wall of the tank body 1 is connected with a guide tube 6, the guide tube 6 and the tank body 1 are integrally formed, a side of the guide tube 6 away from the tank body 1 is threadedly connected with a feed tube 7, the outer surface of one side of the guide tube 6 is threadedly sleeved with the feed tube 7, and a leak-proof gasket made of rubber material can be provided at the threaded connection between the guide tube 6 and the feed tube 7, a filter screen 8 is installed on the inner wall of the feed tube 7, and the material of the filter screen 8 can be a fiber filter screen with strong filtering performance and light weight, which is used to filter impurities, a discharge pipe 10 is provided below the tank body 1, and a blocking mechanism is provided at the bottom of the discharge pipe 10, and the blocking mechanism includes The sealing plug 11, the first spring 13, the slide bar 15, the positioning block 12, the limit block 14 and the ring tube 16 are included. The slide bar 15 is provided at the bottom of the discharge pipe 10, and the limit block 14 is provided at the bottom of the slide bar 15. The top of the slide bar 15 is fixedly connected with the sealing plug 11. During use, the sealing plug 11 needs to be cleaned regularly to ensure its hygiene. A positioning block 12 is provided between the sealing plug 11 and the limit block 14. The positioning block 12 is sleeved on the outer wall of the slide bar 15. The bottom of the positioning block 12 is installed with an annular tube 16, which is a limit for the first spring 13. The outer wall of the slide bar 15 is sleeved with the first spring 13, and the first spring 13 is located between the limit block 14 and the annular tube 16.

[0026] In the specific implementation process, it is worth pointing out that the cooperation between the sealing plug 11, the first spring 13, the slide bar 15, the positioning block 12, the limit block 14 and the ring tube 16 is such that the sealing plug 11 moves vertically at the discharge pipe 10 by pulling the limit block 14. The slide bar 15, in cooperation with the ring tube 16 and the positioning block 12, relies on the elastic deformation of the first spring 13 to achieve the sealing or unsealing of the discharge pipe 10 by the sealing plug 11, which solves the problem that the existing device is easy to float in dust and impurities due to the unblocked filling head, which reduces the filling quality and requires manual cleaning, increasing costs and affecting production efficiency.

[0027] Furthermore, the top of the tank body 1 is connected with a pressure pipe 2, which is a vacuum pipe with a certain pressure resistance. A mounting seat 4 is installed on the top of the pressure pipe 2. The function of the mounting seat 4 is to install the filling head on the filling machine. The top of the mounting seat 4 is fixedly connected with a vacuum pump 22, and the model of the vacuum pump 22 is not limited.

[0028] In the specific implementation process, it is worth pointing out that the output end of the external pressure vacuum pump 22 is fixedly installed on the top of the mounting seat 4, and the bottom of the inner cavity pipeline of the mounting seat 4 is connected to the pressure pipe 2. When the vacuum pump 22 of the filling machine is evacuated, the container filled with liquid forms a negative pressure environment, and then the valve connected to the outside of the feed pipe 7 is opened, and the liquid is sucked into the container to achieve filling;

[0029] Further, one side of the positioning block 12 is fixedly connected to the L-shaped connecting rod 17;

[0030] In the specific implementation process, it is worth pointing out that the purpose of connecting one end of the L-shaped connecting rod 17 to the positioning block 12 is to maintain the overall stability of the device;

[0031] Further, the top of the L-shaped connecting rod 17 is fixedly connected to a limit rod 18, the top of the limit rod 18 is fitted to the bottom of the base 3, the top of the limit rod 18 is fixedly connected to a push rod 19, the push rod 19 is movably connected to the inner wall of the base 3, a movable head 21 is installed on the top of the push rod 19, and the outer wall of the push rod 19 is sleeved with a second spring 20, and the two ends of the second spring 20 are respectively fitted with the bottom of the movable head 21 and the top of the base 3;

[0032] In the specific implementation process, it is worth pointing out that when the user presses the movable head 21, the push rod 19 moves downward under the action of the second spring 20. At the same time, when the push rod 19 moves, based on the action of the limit rod 18, the push rod 19 will not fall off, which increases the stability of the push rod 19. At the same time, because the second spring 20 and the push rod 19 are on the base 3, it is convenient for personnel to use, saves manpower, and improves the convenience of the device.

[0033] Specifically, the user installs the mounting base 4 on the filling machine through the mounting through hole 23, inserts the discharge pipe 10 into the filling container, and the filling machine uses the vacuum pump 22 to evacuate the filling container to form a negative pressure environment. At the same time, the valve connected to the container storing the filling liquid outside the feed pipe 7 is opened, so that the filling liquid is sucked into the feed pipe 7, filtered through the filter screen 8 and flows into the guide pipe 6 into the tank body 1, and then the pressure in the tank is adjusted to a suitable value by adjusting the pneumatic control valve on the filling machine, and the valve on the feed pipe 7 is opened to inject the liquid in the tank body 1 into the container through the discharge pipe 10. When the user completes the filling process, he presses the movable head 21 to move the limit rod 18 downward and drive the positioning rod connected to the L-shaped connecting rod The block 12 is reasonably positioned to the discharge pipe 10, so that the sealing plug 11 can just enter the discharge pipe 10 to block it, so that dust or other impurities in the working environment cannot enter the discharge pipe 10, thereby ensuring its internal hygiene. When the user performs the filling work again, he pulls the limit block 14, drives the slide bar 15 to move downward and at the same time brings out the sealing plug 11 to unseal the discharge pipe 10. At the same time, with the cooperation of the first spring 13 and the positioning block 12, the sealing plug 11 returns to its original position along the slide bar 15, and then the user pulls the limit block 14 to make it move axially. At the same time, with the cooperation of the limit rod 18 and the ring tube 16, the push rod 19 moves up and returns to its original position by relying on the elastic deformation of the second spring 20, without affecting the subsequent filling work.

[0034] Embodiment 2: By Figure 1-3 It can be seen that the end of the tank body 1 away from the mounting seat 4 is connected to the end head 5 through the disassembly flange 9, and the bottom of the end head 5 is connected to the discharge pipe 10;

[0035] In the specific implementation process, it is worth pointing out that the bottom and the end of the tank body 1 of the device are connected by a disassembly flange 9, the structure is simple and easy to disassemble, and at the same time it maintains good sealing, and is convenient for disassembly and cleaning to improve work efficiency. The discharge pipe 10 is designed in this way to quickly insert into the container mouth, which greatly improves production efficiency;

[0036] Furthermore, mounting holes 23 are provided on both sides of the top of the mounting seat 4;

[0037] In the specific implementation process, it is worth pointing out that the user installs the filling head on the filling machine through the installation through hole 23;

[0038] Specifically, based on the above-mentioned embodiment 1, the user installs or removes the filling head through the installation through hole 23. When the end head 5 or the discharge pipe 10 is blocked by debris, it is only necessary to remove the fastening bolts of the disassembly flange 9, which is convenient for the staff to perform maintenance or cleaning work inside the filling head, thereby facilitating manpower and improving production efficiency.
