Description

Technical Field

[0001] This utility model relates to the field of filling head technology, and in particular to a filling head that prevents material splashing. Background Technology

[0002] The filling head is a key component in filling equipment, mainly used to accurately fill liquid or semi-fluid materials into various containers. It is usually made of corrosion-resistant materials such as stainless steel and has different structures and types to adapt to different filling needs. In the dairy industry production line, the filling head plays an important role and is one of the key elements to achieve efficient and accurate filling production.

[0003] Most filling heads on the market use a straight cylindrical structure. In actual milk conveying operations, when milk flows out of the filling head, the straight cylindrical structure lacks an effective control mechanism for the flow rate and direction of the milk. As a result, the milk will directly impact the edge of the conveying port at a relatively high speed. The strong impact causes the kinetic energy of the milk to be dispersed instantly, and the milk droplets are very easy to splash in all directions, affecting production operations. This needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies where most filling heads use a straight cylindrical structure. In actual milk conveying operations, when milk flows out of the filling head, the lack of an effective control mechanism for the milk flow rate and direction causes the milk to directly impact the edge of the conveying port at a relatively high speed. The strong impact causes the kinetic energy of the milk to be dispersed instantly, and the milk droplets are easily splashed in all directions, affecting production operations. Therefore, this invention proposes a filling head that prevents material splashing.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a filling head for preventing material splashing, comprising a conduit and a threaded cylinder. The lower end of the conduit is fixedly connected to a threaded head, and the threaded cylinder is threadedly installed on the threaded head. The lower end of the threaded cylinder is fixedly connected to a connector, and the surface of the connector is provided with a flow guiding device. The flow guiding device includes a flow guiding cylinder, which is fixedly connected to the lower surface of the connector. A rotating cylinder is rotatably connected to the inner wall of the flow guiding cylinder, and a flow guiding vane is fixedly connected to the inner wall of the rotating cylinder. A protective cover is fixedly connected to the lower end of the flow guiding cylinder. A stabilizing device is provided on the surface of the conduit. When milk flows into the flow guiding cylinder and impacts the flow guiding vane, the rotating cylinder rotates inside the flow guiding cylinder. Because the inclined plate of the flow guiding vane is inclined, the milk will be spirally guided along the inclined direction. This flow guiding method can effectively disperse the flow rate and impact force of the milk, making the milk flow more evenly and concentratedly downwards, avoiding splashing of milk due to excessive flow rate.

[0006] Preferably, a first filter screen is placed inside the connector, a first pressure ring is placed above the first filter screen, a second filter screen is placed below the first pressure ring, a second pressure ring is fitted on the second filter screen, the second pressure ring is located in the connector, and the lower end of the threaded head abuts against the upper surface of the second pressure ring.

[0007] Preferably, the guide vane consists of a circular support rod and eight inclined plates arranged in a circular array, which facilitates the gathering and downward conveying of milk, avoiding milk splashing.

[0008] Preferably, the outer diameters of the first filter screen, the first pressure ring, the second filter screen, and the second pressure ring are all adapted to the inner diameter of the connector. While filtering, the first and second filter screens also buffer and uniformly distribute the milk flow, allowing the milk to pass through the filling head at a relatively stable flow rate. This helps to achieve more accurate quantitative filling, ensuring that the volume of each bag of milk meets the standard, reducing product weight errors, and improving product consistency and market competitiveness.

[0009] Preferably, the stabilizing device includes a mounting ring, which is fixedly connected to the surface of the conduit. A guide rod is fixedly connected to the lower surface of the mounting ring, and a positioning ring is slidably connected to the guide rod. A limit rod is fixedly connected to the lower surface of the positioning ring, and a retaining sleeve is fixedly connected to the surface of the threaded cylinder. One end of the limit rod is inserted into the retaining sleeve. By inserting the limit rod into the retaining sleeve, the threaded sleeve is prevented from loosening during the use of the filling head, thus ensuring stable use of the equipment.

[0010] Preferably, a stop is fixedly connected to the lower end of the guide rod to restrict the movement of the positioning ring.

[0011] Preferably, a magnet is installed on the lower surface of the mounting ring. When the positioning ring is pulled upward, it is attracted by the magnet, facilitating positioning. By sliding the positioning ring upward and using the magnet for positioning, the threaded cylinder can be easily screwed onto the threaded head to complete the connection. Then, pulling the positioning ring downward causes the limiting rod to insert into the sleeve, achieving positioning and fixing of the threaded cylinder. This simplifies the installation process of the filling head, saves installation time and labor costs, and effectively prevents the threaded cylinder from loosening or shifting due to vibration or other factors during use. This ensures the stability of the entire filling head structure, reduces failures and maintenance needs caused by structural instability, and improves the reliability and service life of the equipment.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, the first and second filters, while filtering, also buffer and even out the flow of milk, allowing it to pass through the filling head at a relatively stable flow rate. This helps achieve more precise quantitative filling, ensuring that the volume of each bag of milk meets the standard, reducing product weight errors, and improving product consistency and market competitiveness. When the milk flows into the guide tube and impacts the guide vanes, the rotating drum rotates inside the guide tube. Because the inclined plate of the guide vanes is tilted, the milk will be spirally guided along the inclined direction. This guiding method can effectively disperse the flow rate and impact force of the milk, making the milk flow more evenly and uniformly downwards, avoiding splashing caused by excessive flow rate.

[0014] In this invention, by sliding the positioning ring upwards and using a magnet for positioning, the threaded cylinder can be easily screwed onto the threaded head to complete the connection. Then, by pulling the positioning ring downwards, the limiting rod is inserted into the sleeve, thereby positioning and fixing the threaded cylinder. This simplifies the installation process of the filling head, saves installation time and labor costs, and effectively prevents the threaded cylinder from loosening or shifting due to vibration or other factors during use. This ensures the stability of the entire filling head structure, reduces malfunctions and maintenance needs caused by structural instability, and improves the reliability and service life of the equipment.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a filling head for preventing material splashing, including a conduit 1 and a threaded cylinder 3. The lower end of the conduit 1 is fixedly connected to a threaded head 2, and the threaded cylinder 3 is threaded onto the threaded head 2. The lower end of the threaded cylinder 3 is fixedly connected to a connector 4. The surface of the connector 4 is provided with a flow guiding device 5, which includes a flow guiding cylinder 52. The flow guiding cylinder 52 is fixedly connected to the lower surface of the connector 4. The inner wall of the flow guiding cylinder 52 is rotatably connected to a rotating cylinder 54, and the inner wall of the rotating cylinder 54 is fixedly connected to a flow guiding blade 53. The lower end of the flow guiding cylinder 52 is fixedly connected to a protective cover 51. The surface of the conduit 1 is provided with a stabilizing device 6. When milk flows into the flow guiding cylinder 52 and impacts the flow guiding blade 53, the rotating cylinder 54 rotates inside the flow guiding cylinder 52. Since the inclined plate of the flow guiding blade 53 is inclined, the milk will be spirally guided along the inclined direction. This flow guiding method can effectively disperse the flow rate and impact force of the milk, making the milk flow more evenly and concentratedly downward, avoiding splashing of milk due to excessive flow rate.

[0023] In this embodiment: a first filter screen 56 is placed inside the connector 4, a first pressure ring 55 is placed above the first filter screen 56, a second filter screen 58 is placed below the first pressure ring 55, a second pressure ring 57 is sleeved on the second filter screen 58, the second pressure ring 57 is located in the connector 4, and the lower end of the threaded head 2 abuts against the upper surface of the second pressure ring 57.

[0024] Specifically, the guide vane 53 consists of a circular support rod and eight inclined plates arranged in a circular array, which facilitates the gathering and downward conveying of milk, preventing milk from splashing.

[0025] Specifically, the outer diameters of the first filter screen 56, the first pressure ring 55, the second filter screen 58, and the second pressure ring 57 are all adapted to the inner diameter of the connector 4. While filtering, the first filter screen 56 and the second filter screen 58 also buffer and even out the flow of milk, allowing the milk to pass through the filling head at a relatively stable flow rate. This helps to achieve more accurate quantitative filling, ensuring that the volume of each bag of milk meets the standard, reducing product weight errors, and improving product consistency and market competitiveness.

[0026] In this embodiment: the stabilizing device 6 includes a mounting ring 61, which is fixedly connected to the surface of the conduit 1. A guide rod 62 is fixedly connected to the lower surface of the mounting ring 61. A positioning ring 64 is slidably connected to the guide rod 62. A limiting rod 65 is fixedly connected to the lower surface of the positioning ring 64. A retaining sleeve 66 is fixedly connected to the surface of the threaded cylinder 3. One end of the limiting rod 65 is inserted into the retaining sleeve 66. By inserting the limiting rod 65 into the retaining sleeve 66, the threaded sleeve is prevented from becoming loose during the use of the filling head, thus ensuring stable use of the equipment.

[0027] Specifically, a stop 63 is fixedly connected to the lower end of the guide rod 62 to restrict the movement of the positioning ring 64.

[0028] Specifically, a magnet 67 is installed on the lower surface of the mounting ring 61. When the positioning ring 64 is pulled upward, it is attracted by the magnet 67, which facilitates positioning. By sliding the positioning ring 64 upward and using the magnet 67 for positioning, the threaded cylinder 3 can be easily screwed onto the threaded head 2 to complete the connection. Then, by pulling the positioning ring 64 downward, the limiting rod 65 is inserted into the sleeve 66, thereby positioning and fixing the threaded cylinder 3. This simplifies the installation process of the filling head, saves installation time and labor costs, and effectively prevents the threaded cylinder 3 from loosening or shifting due to vibration or other factors during use. This ensures the stability of the entire filling head structure, reduces failures and maintenance needs caused by structural instability, and improves the reliability and service life of the equipment.

[0029] Working principle: When installing the filling head, slide the positioning ring 64 upwards. After the magnet 67 attracts the positioning ring 64, the threaded cylinder 3 can be screwed onto the threaded head 2. After the connection between the threaded cylinder 3 and the threaded head 2 is completed, pull the positioning ring 64 downwards. The positioning ring 64 then disengages from the magnet 67 and drives the limiting rod 65 to insert into the sleeve 66, thereby positioning and fixing the threaded cylinder 3 and preventing it from loosening or shifting due to vibration during use, ensuring the stability of the entire filling head structure. Milk flows in from the conduit 1. Since the lower end of the conduit 1 is fixedly connected to the threaded head 2, the threaded cylinder 3 is threaded onto the threaded head 2, thus achieving a stable connection between the conduit 1 and subsequent components, ensuring that milk can smoothly enter the threaded cylinder 3 from the conduit 1 and then be conveyed downwards through the connector 4. The connector 4 contains a first filter screen 56 and a second filter screen 58, which work together with the first pressure ring 55 and the second pressure ring 57. The first filter screen 56 and the second filter screen 58 perform preliminary filtration of the material. At the same time, the first filter screen 56 and the second filter screen 58 can buffer and uniform the flow of milk, allowing the milk to pass through the filling head at a relatively stable flow rate. This helps to achieve more accurate quantitative filling, ensuring that the volume of each bag of milk meets the standard and reducing product weight error. When the milk flows into the guide tube 52 from the connector 4, it impacts the guide vane 53, causing the rotating drum 54 to rotate inside the guide tube 52. Since the inclined plate of the guide vane 53 is inclined, the direction of movement of the milk is changed during the impact of the guide vane 53. It no longer flows in a straight line vertically downward, but is spirally guided along the inclined direction of the guide vane 53. This guiding method can effectively disperse the flow rate and impact force of the material, making the material flow more evenly and concentratedly downward, avoiding milk splashing. The protective cover 51 protects the guide tube 52 during operation.
