Description

Technical Field

[0001] This application relates to the field of filling machine technology, and in particular to a sealed nozzle structure for a filling machine. Background Technology

[0002] Existing filling machines are a type of packaging machine and play an important role in the packaging industry. With the rapid development of industries such as food, cosmetics, and pharmaceuticals, the demand for filling machines is also increasing. With the advancement of mechanical technology, filling machines have become mechanized, improving production efficiency and filling quality.

[0003] Traditional filling machines use nozzles to deliver liquid from a storage tank into a storage bottle. However, since the nozzles on traditional filling machines can only be used with one type of storage bottle, different nozzles need to be used to fill different types of storage bottles. This is inconvenient for operators and needs to be improved. Utility Model Content

[0004] In order to enable the filling machine to be compatible with different sizes of liquid storage bottles, this application provides a sealed nozzle structure for the filling machine.

[0005] This application provides a sealed nozzle structure for a filling machine, which adopts the following technical solution:

[0006] A sealed nozzle structure for a filling machine includes a base and a fixed base. The base is provided with a pressing mechanism for pressing the fixed base downward. The fixed base is provided with a liquid inlet pipe for connecting to a liquid storage tank, a nozzle for conveying liquid to a liquid storage bottle, and a liquid outlet pipe for connecting the fixed base and the nozzle. The nozzle is provided with multiple nozzles of different specifications. The end of the liquid outlet pipe away from the fixed base is provided with a sliding assembly for sliding and replacing the connection between different nozzles and the liquid outlet pipe. Any of the nozzles is mounted on the sliding assembly.

[0007] By adopting the above technical solution and utilizing the sliding component, the operator can select the appropriate nozzle as needed and move the nozzle to a position that can connect with the liquid outlet pipe through the sliding component, thereby adapting to different specifications of storage bottles. Then, by pressing down the fixed seat through the holding mechanism, the fixed seat can drive the nozzle to move downward and enter the liquid storage bottle for filling operations. This design makes the entire filling process more efficient and flexible.

[0008] Preferably, the nozzle is provided with a sealing component for sealing the mouth of the liquid storage bottle.

[0009] By adopting the above technical solution and utilizing the sealing component, the sealing component can create a sealed environment in the liquid storage bottle during filling, preventing liquid from splashing out of the liquid storage bottle during the filling process, thereby improving the accuracy and safety of the filling operation.

[0010] Preferably, the sealing assembly includes a sealing block and a sealing ring, both of which are fixedly mounted on the nozzle. The upper surface of the sealing ring abuts against the sealing block, and the lower surface of the sealing ring abuts against the liquid storage bottle.

[0011] By adopting the above technical solution and using the sealing block and sealing ring, the liquid storage bottle can maintain a good sealing effect even under high pressure or high speed filling conditions, thus enhancing the sealing performance between the nozzle and the liquid storage bottle.

[0012] Preferably, any of the nozzles is provided with a circumferential array of through holes for adjusting the internal air pressure of the liquid storage bottle.

[0013] By adopting the above technical solution, through the through holes arranged in a circumferential array on the nozzle, the amount of air entering the liquid in the storage bottle from the liquid outlet pipe can be reduced, thereby improving the filling quality.

[0014] Preferably, the sliding assembly includes a fixed plate and a sliding plate, the fixed plate is connected to the liquid outlet pipe, the sliding plate is slidably mounted on the fixed plate, and any of the nozzles is mounted on the sliding plate.

[0015] By adopting the above technical solution and utilizing the sliding plate, the position of the nozzle on the sliding plate can be precisely adjusted, ensuring that the selected nozzle can accurately reach the predetermined filling position during the movement, thereby improving the accuracy and efficiency of filling.

[0016] Preferably, the fixed plate is provided with a limiting member for restricting the position of the sliding plate, the limiting member passing through the fixed plate and forming an abutting fit with the sliding plate.

[0017] By adopting the above technical solution and utilizing the setting of the limiting component, after the required nozzle is slid to connect with the liquid outlet pipe, the limiting component can limit the position of the sliding plate, ensuring the stability of the sliding plate and nozzle during the filling process, so that the liquid flowing out of the liquid outlet pipe can smoothly enter the storage bottle.

[0018] Preferably, the pressing mechanism includes a limiting seat and a cylinder. The limiting seat is disposed on the base, the cylinder is disposed on the limiting seat, the fixed seat is fixedly connected to the piston rod of the cylinder, and the limiting seat is provided with a clearance hole for avoiding the piston rod of the cylinder.

[0019] By adopting the above technical solution and utilizing the setting of the limit seat, the cylinder can maintain a stable position during operation, and the cylinder drives the piston rod to achieve a fast and stable downward pressing action. Thus, the piston rod of the cylinder can drive the fixed seat and the nozzle to move downward, thereby improving the filling efficiency.

[0020] Preferably, a first sealing head is provided at the end of the liquid inlet pipe away from the liquid storage tank, and the first sealing head is threadedly connected to the fixed seat.

[0021] By adopting the above technical solution, the first sealing head is threadedly connected to the fixed seat, which facilitates the replacement or cleaning of the first sealing head by the staff, while ensuring the sealing of the connection between the fixed seat and the liquid inlet pipe.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By utilizing the sliding component, staff can select the appropriate nozzle as needed and move it to a position that can connect with the liquid outlet pipe, thus adapting to different sizes of storage bottles. Then, by pressing down the fixed seat through the holding mechanism, the fixed seat can drive the nozzle to move downward and enter the storage bottle for filling. This design makes the entire filling process more efficient and flexible.

[0024] 2. By utilizing the sealing component, the liquid storage bottle can form a sealed environment during filling, preventing liquid from splashing out of the bottle during the filling process, thereby improving the accuracy and safety of the filling operation;

[0025] 3. By utilizing the through holes arranged in a circumferential array on the nozzle, the design of the through holes can reduce the amount of air entering the liquid in the storage bottle from the liquid outlet pipe, thereby improving the filling quality. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0029] This application discloses a sealed nozzle structure for a filling machine.

[0030] Reference Figure 1A sealed nozzle structure for a filling machine includes a base 1 and a fixed base 2. The base 1 is provided with a pressing mechanism 11 for pressing the fixed base 2 downward. The pressing mechanism 11 includes a limiting seat 111 and a cylinder 112. The base 1 is also provided with a fixing rod 12. Multiple fixing rods 12 are provided. In this embodiment, two fixing rods 12 are provided. The two ends of any fixing rod 12 are welded to the base 1, and any fixing rod 12 passes through the limiting seat 111 and is welded and fixed to the limiting seat 111, thereby realizing the fixation of the limiting seat 111.

[0031] Reference Figure 1 The cylinder 112 is connected to the limit seat 111 by bolt thread. The limit seat 111 is provided with a relief hole 1111 for avoiding the piston rod of the cylinder 112, so that the piston rod of the cylinder 112 can pass through the limit seat 111 and be fixedly connected to the fixed seat 2. The limit seat 111 can ensure that the cylinder 112 can maintain a stable position during operation.

[0032] Reference Figure 1 In this embodiment, a connecting plate 21 is connected to the fixed base 2 by bolts and threads. The piston rod of the cylinder 112 is welded and fixed to the connecting plate 21. The connecting plate 21 enhances the connection stability between the piston rod of the cylinder 112 and the fixed base 2, thereby ensuring that the piston rod of the cylinder 112 can always remain stable with the fixed base 2 during operation.

[0033] Reference Figure 1 The fixed base 2 is provided with an inlet pipe 22 for connecting the liquid storage tank and an outlet pipe 23 and a nozzle 24 for conveying liquid to the liquid storage bottle. The outlet pipe 23 is connected to the side of the fixed base 2 away from the connecting plate 21, that is, the inlet pipe 22 and the outlet pipe 23 are connected through the inside of the fixed base 2. A first sealing head 221 is installed at the end of the inlet pipe 22 away from the liquid storage tank. The first sealing head 221 is threadedly connected to the fixed base 2. A second sealing head 231 is installed at the end of the outlet pipe 23 away from the nozzle 24. The second sealing head 231 is threadedly connected to the fixed base 2.

[0034] Reference Figure 1 The use of the first sealing head 221 and the second sealing head 231 facilitates the replacement or cleaning of the first sealing head 221 and the second sealing head 231 by the staff, while ensuring the sealing of the connection between the fixed seat 2 and the liquid inlet pipe 22 and between the fixed seat 2 and the liquid outlet pipe 23.

[0035] Reference Figure 1 The nozzle 24 is provided in multiple ways. In this embodiment, the nozzle 24 is provided in three different sizes. The end of the liquid outlet pipe 23 away from the fixed base 2 is provided with a sliding component 25 for sliding and replacing the connection between the nozzle 24 of different sizes and the liquid outlet pipe 23. The sliding component 25 includes a fixed plate 251 and a sliding plate 252.

[0036] Reference Figure 1 A third sealing head 232 is installed at one end of the liquid outlet pipe 23 near the nozzle 24. The third sealing head 232 is welded to the fixing plate 251, and the fixing plate 251 is connected to the liquid outlet pipe 23 through the third sealing head 232. The setting of the third sealing head 232 makes it convenient for staff to replace or clean the third sealing head 232, while ensuring the sealing of the connection between the liquid outlet pipe 23 and the nozzle 24.

[0037] Reference Figure 1 The fixed plate 251 is provided with a downward-facing sliding groove 2511. The sliding plate 252 and the sliding groove 2511 of the fixed plate 251 form a sliding fit. Any nozzle 24 is threadedly connected to the sliding plate 252. In actual operation, the operator slides the sliding plate 252 and slides the appropriate nozzle 24 to the underside of the third sealing head 232 according to the needs of the liquid storage bottle. At this time, the nozzle 24 can pass through the sliding plate 252 and be threadedly connected to the liquid outlet pipe 23.

[0038] Reference Figure 1 The fixed plate 251 is provided with limiting members for restricting the position of the sliding plate 252. There are multiple limiting members. In this embodiment, there are four limiting members. Each limiting member is a limiting bolt 2512. Each limiting bolt 2512 passes through the fixed plate 251 and forms an abutting fit with the sliding plate 252. After the required nozzle 24 is slid to connect with the liquid outlet pipe 23, the limiting bolt 2512 can abut and limit the position of the sliding plate 252, ensuring the stability of the sliding plate 252 and the nozzle 24 during the filling process, so that the liquid flowing out of the liquid outlet pipe 23 can smoothly enter the storage bottle.

[0039] Reference Figure 1 Each nozzle 24 is equipped with a sealing component 241 for sealing the mouth of the liquid storage bottle. Since the structure and connection method of the three sealing components 241 are the same, we will now describe one of the sealing components 241 as an example.

[0040] Reference Figure 1 The sealing assembly 241 includes a sealing block 2411 and a sealing ring 2412. Both the sealing block 2411 and the sealing ring 2412 are fixedly mounted on the nozzle 24. In this embodiment, the sealing block 2411 and the sealing ring 2412 are welded to one end of the nozzle 24 near the sliding plate 252. The upper surface of the sealing ring 2412 forms an abutting fit with the sealing block 2411, and the lower surface of the sealing ring 2412 forms an abutting fit with the liquid storage bottle.

[0041] Reference Figure 1By using the sealing block 2411 and the sealing ring 2412, a sealed environment is formed in the liquid storage bottle under high pressure or high speed filling conditions, preventing liquid from splashing out of the liquid storage bottle during the filling process, thereby improving the accuracy and safety of the filling operation.

[0042] Reference Figure 1 Each nozzle 24 is provided with a circumferential array of through holes 242 for adjusting the air pressure inside the liquid storage bottle. In this embodiment, two through holes 242 are symmetrically arranged. The through holes 242 can reduce the amount of air in the liquid outlet pipe 23 entering the liquid in the liquid storage bottle, thereby improving the filling quality. At the same time, when the liquid in the liquid storage bottle submerges the through holes 242, the pressure inside the liquid storage bottle will gradually increase until it is the same as the pressure inside the liquid storage tank. This prevents the liquid in the liquid outlet pipe 23 from entering the liquid storage bottle, thereby realizing automatic control of the filling capacity and ensuring that the total amount of liquid inside each liquid storage bottle is the same.

[0043] The implementation principle of this application embodiment is as follows: In actual operation, the operator slides the sliding plate 252 according to the needs of the liquid storage bottle and slides the appropriate nozzle 24 directly below the third sealing head 232. At this time, the nozzle 24 can pass through the sliding plate 252 and be threadedly connected to the liquid outlet pipe 23, so that the filling machine can be adapted to the use of nozzles 24 of different specifications. Then, the cylinder 112 is operated to press down the fixed seat 2, so that the fixed seat 2 can drive the nozzle 24 to move downward and enter the liquid storage bottle for filling operation.

[0044] When the liquid in the storage bottle submerges the through hole 242, the pressure inside the storage bottle will gradually increase until it is the same as the pressure inside the storage tank. This prevents the liquid in the outlet pipe 23 from entering the storage bottle, thus achieving automatic control of the filling capacity and ensuring that the total amount of liquid inside each storage bottle is the same.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
