Description

Technical Field

[0001] This utility model relates to the field of filling machine technology, specifically to a discharge unit of a vacuum mixing kettle for a filling machine. Background Technology

[0002] In the field of filling machine manufacturing, vacuum mixing kettles, as key equipment for material mixing and processing, are widely used in the food, pharmaceutical, and chemical industries, especially suitable for scenarios requiring high material purity and avoiding oxidation or contamination. The discharge unit of the vacuum mixing kettle, as the core transitional component connecting the mixing kettle and the filling mechanism, directly affects filling efficiency, material quality, and production stability.

[0003] In existing equipment, most of the feeding sections use top filling, which cannot meet the requirements of the vacuum process. Moreover, the sealing requirements in a vacuum environment are extremely high. Single-group seals or simple sealing structures are difficult to adapt to long-term high pressure differential conditions, which can easily lead to material leakage or external air infiltration. This not only wastes materials but may also damage the vacuum environment, causing material oxidation and contamination, and affecting product quality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a discharge unit for a vacuum mixing kettle for a filling machine, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a discharge unit of a vacuum mixing kettle for a filling machine, including a discharge part and a mounting block located in front of the discharge part. The discharge part has a discharge port at one end near the mounting block. A connecting block is provided at one end of the mounting block away from the discharge part. A connecting pipe is fixedly installed at one end of the connecting block away from the mounting block. A guide post is fixedly installed at one corner of the mounting block near the connecting block. A groove is provided at the center of one end of the mounting block near the connecting block. A positioning hole is provided at one end of the connecting block near the mounting block. A sealing ring is embedded at the center of one end of the connecting block near the mounting block.

[0006] Preferably, a fixing seat is fixedly installed on both the left and right sides of the feeding part, a fixing block is welded and installed on both ends of the outer side of the feeding part away from the fixing seat, a fixing rod is welded and installed on the inner surface of the fixing block, and a connecting pipe one and a connecting pipe two are fixedly installed on the outer surface of the feeding part between the fixing seat and the mounting block.

[0007] By using the above technical solution, fixing seats are installed on both the left and right sides of the feeding section, making it easy to fix the entire discharge unit to the bottom of the vacuum mixing vessel, thus improving the installation stability of the overall structure.

[0008] Preferably, the guide post and the positioning hole have the same cross-section, the guide post and the positioning hole are plugged in, and the connecting block is provided with a locking nut that is threadedly connected to the guide post on the side away from the mounting block.

[0009] The above technical solution, with its plug-in design using guide posts and positioning holes, enables precise positioning of the connecting blocks and mounting blocks during installation, improving installation efficiency. After the connecting blocks and mounting blocks are installed, the threaded connection between the locking nut and the guide post allows for quick fixing of the connecting blocks and mounting blocks. Furthermore, the threaded connection facilitates the detachable installation of the connecting blocks and mounting blocks, making subsequent cleaning and maintenance easier.

[0010] Preferably, the sealing ring has a circular cross-section, and three identical sets of sealing rings are provided, with the three sets of sealing rings evenly spaced and distributed in a ring on the outer surface of the connecting block.

[0011] The above technical solution, by setting the cross-section of the sealing ring to be "circular", can accommodate the tiny gap between the connecting block and the mounting block, effectively preventing material leakage. Furthermore, by setting three sets of equally spaced annularly distributed sealing rings, the sealing performance between the connecting block and the mounting block is further improved. Even if one set of sealing rings fails to seal due to wear, aging, etc., the other two sets can still play a sealing role, reducing the risk of material leakage.

[0012] Preferably, the sealing ring has the same cross-section as the groove, and the sealing ring can be inserted into the groove.

[0013] The above technical solution allows the sealing ring to be inserted into the groove, which in turn limits the sealing ring and prevents it from shifting during operation, thereby further improving the sealing effect between the connecting block and the mounting block.

[0014] Preferably, a regulating valve is provided at the top of the connecting pipe, and the regulating valve is connected to the connecting pipe.

[0015] The above technical solution allows for direct control of the flow rate and velocity of materials within the connecting pipe by installing a regulating valve at the top of the connecting pipe, facilitating flexible adjustment of the discharge volume according to filling requirements.

[0016] Compared with the prior art, this utility model provides a discharge unit for a vacuum mixing tank in a filling machine, which has the following advantages:

[0017] 1. The discharge unit of the vacuum mixing tank of this filling machine is designed with a plug-in installation through guide columns and positioning holes. This design can accurately position the connecting blocks and mounting blocks during installation, improving installation efficiency. After the connecting blocks and mounting blocks are installed, the connecting blocks and mounting blocks can be quickly fixed by the threaded connection of the locking nut and the guide column. The threaded connection also facilitates the detachable installation of the connecting blocks and mounting blocks, making it easy to clean and maintain later.

[0018] 2. The filling machine uses a vacuum mixing tank discharge unit. The material in the vacuum mixing tank first enters the feeding section and is conveyed to the connecting pipe through the discharge port at the bottom of the feeding section. By setting a regulating valve at the top of the connecting pipe, the flow rate and velocity of the material in the connecting pipe can be directly controlled, which makes it easy to flexibly adjust the discharge amount according to the filling requirements.

[0019] 3. The discharge unit of the vacuum mixing vessel used in this filling machine is equipped with three sets of circular sealing rings through the connection between the connecting block and the mounting block. All three sets of circular sealing rings can be inserted into the groove to form a multi-seal structure. Combined with the pressure difference under vacuum environment, it effectively prevents material leakage and external air infiltration, and maintains a stable vacuum state.

[0027] Example 1: As Figure 1-5 As shown, the present invention provides a discharge unit for a vacuum mixing vessel for a filling machine, including a discharge section 1 and a mounting block 7 located in front of the discharge section 1. The discharge section 1 has a discharge port 8 at one end near the mounting block 7. The mounting block 7 has a connecting block 9 at one end away from the discharge section 1. A connecting pipe 10 is fixedly installed at one end of the connecting block 9 away from the mounting block 7. A guide post 12 is fixedly installed at one corner of the mounting block 7 near the connecting block 9.

A sealing ring 15 is embedded in the center of one end of the connecting block 9 near the mounting block 7.

[0028] Specifically, fixing seats 2 are fixedly installed on both the left and right sides of the feeding section 1. Fixing blocks 3 are welded to the two ends of the feeding section 1 away from the fixing seats 2. Fixing rods 4 are welded to the inner surface of the fixing blocks 3. Connecting pipe 1 5 and connecting pipe 2 6 are fixedly installed on the outer surface of the feeding section 1 between the fixing seats 2 and the mounting blocks 7. The advantage is that by fixing the fixing seats 2 on both the left and right sides of the feeding section 1, it is easy to fix the entire discharge unit to the bottom of the vacuum mixing vessel, thus improving the installation stability of the overall structure.

[0029] Specifically, the guide post 12 and the positioning hole 14 have the same cross-section, and the guide post 12 and the positioning hole 14 are plug-in installed. A locking nut 16, threadedly connected to the guide post 12, is provided on the side of the connecting block 9 away from the mounting block 7. The advantages are that the plug-in design of the guide post and the positioning hole 14 provides precise positioning during the installation of the connecting block 9 and the mounting block 7, improving installation efficiency. After the connecting block 9 and the mounting block 7 are installed, the threaded connection between the locking nut 16 and the guide post 12 allows for quick fixing of the connecting block 9 and the mounting block 7. Furthermore, the threaded connection facilitates the detachable installation of the connecting block 9 and the mounting block 7, making subsequent cleaning and maintenance easier.

[0030] Specifically, the sealing ring 15 has a circular cross-section, and three identical sets of sealing rings 15 are evenly spaced and distributed in a ring on the outer surface of the connecting block 9. The advantage is that the circular cross-section of the sealing rings 15 can accommodate small gaps between the connecting block 9 and the mounting block 7, effectively preventing material leakage. Furthermore, the three equally spaced rings 15 further improve the sealing performance between the connecting block 9 and the mounting block 7. Even if one set of sealing rings 15 fails due to wear or aging, the other two sets can still provide a seal, reducing the risk of leakage.

[0031] Example 2: Figure 2-5 As shown, this is an improvement on the previous embodiment.

[0032] Specifically, the sealing ring 15 and the groove 13 have the same cross-section, and the sealing ring 15 can be inserted into the groove 13. The advantage is that by setting the sealing ring 15 to be inserted into the groove 13, the groove 13 can limit the sealing ring 15, prevent the sealing ring 15 from shifting during operation, and further improve the sealing effect between the connecting block 9 and the mounting block 7.

[0033] Specifically, a regulating valve 11 is installed at the top of the connecting pipe 10, and the regulating valve 11 is connected to the connecting pipe 10. The advantage is that by installing the regulating valve 11 at the top of the connecting pipe 10, the flow rate and velocity of the material in the connecting pipe 10 can be directly controlled, making it easy to flexibly adjust the discharge volume according to filling requirements.

[0034] Working Principle: During use, fixing seats 2 are fixedly installed on both the left and right sides of the feeding section 1, which facilitates the fixation of the entire discharge unit to the bottom of the vacuum mixing vessel, improving the overall structural stability. The guide column and positioning hole 14 are designed for plug-in installation, providing precise positioning when installing the connecting block 9 and mounting block 7, improving installation efficiency. After the connecting block 9 and mounting block 7 are installed, the locking nut 16 is threadedly connected to the guide column 12, enabling quick fixing of the connecting block 9 and mounting block 7. The threaded connection also facilitates the detachable installation of the connecting block 9 and mounting block 7. For later cleaning and maintenance, three sets of circular sealing rings 15 are set through the connection between the connecting block 9 and the mounting block 7, and all three sets of circular sealing rings 15 can be inserted into the groove 13 to form a multi-seal structure. Combined with the pressure difference under vacuum environment, it effectively prevents material leakage and external air infiltration, and maintains a stable vacuum state. Then, the material in the vacuum mixing vessel first enters the feeding section 1 and is conveyed to the connecting pipe 10 through the discharge port 8 at the bottom of the feeding section 1. By setting the regulating valve 11 at the top of the connecting pipe 10, the flow rate and velocity of the material in the connecting pipe 10 can be directly controlled, which makes it easy to flexibly adjust the discharge amount according to the filling requirements.
