Description

Technical Field

[0001] This utility model relates to the field of liquid product manufacturing technology, and in particular to a filling head and a filling machine. Background Technology

[0002] A filling machine is a device used to fill liquid products (such as drinking water, juice, milk, or condiments) into designated containers. It generally controls the filling volume of the liquid product through a filling head. The filling head usually includes a filling tube with a liquid outlet at one end and a plug that is movably installed inside the filling tube. When the liquid product is introduced into the filling tube and the plug is kept separate from the liquid outlet, the liquid product can flow from the liquid outlet into the designated container. When the filling volume reaches the required level, the plug is inserted into the liquid outlet to close the liquid outlet and complete the filling operation.

[0003] To ensure a tight seal between the plug and the outlet, existing technologies install rubber components (such as rubber sealing rings or rubber sealing heads) on the plug. However, this approach increases the number of unsanitary areas on the plug (such as the seam between the rubber component and the plug), making it easy for dirt and grime to accumulate, which can lead to quality problems with the liquid product. Furthermore, the rubber component wears down rapidly during frequent opening and closing, resulting in a decreased seal between the plug and the outlet, which can cause various problems such as leakage and inaccurate filling volume. Therefore, there is an urgent need to develop a new type of filling head. Utility Model Content

[0004] The purpose of this invention is to overcome the technical problems of existing filling heads, which use rubber components to enhance sealing, making it easy for dirt and grime to accumulate and cause liquid product quality issues, and also easy for wear to lead to leakage; and to provide a filling head and filling machine.

[0024] Example 1 like Figures 1 to 4 As shown, a filling head includes a filling tube 1, a telescopic device 2, a connecting rod 3, and a sealing head 4. One end of the filling tube 1 has a liquid outlet 10, and the other end of the filling tube 1 is connected to the telescopic device 2. The telescopic direction of the telescopic device 2 is parallel to the axial direction of the liquid outlet 10. The connecting rod 3 is disposed inside the filling tube 1, with one end connected to the telescopic device 2 and the other end of the connecting rod 3 having a sealing head 4. The sealing head 4 includes a spherical crown section 41 and a cylindrical section 42. One end of the spherical crown section 41 is connected to the end of the connecting rod 3 away from the telescopic device 2. The other end of segment 41 protrudes away from the connecting rod 3; a cylindrical segment 42 is located at the end of the spherical cap segment 41 away from the connecting rod 3, and the diameter of the cylindrical segment 42 is smaller than the diameter of the connecting rod 3; correspondingly, the liquid outlet 10 includes a circular hole segment 101 and a ball-and-socket segment 102, the shape of the circular hole segment 101 matches the shape of the cylindrical segment 42, and the end of the circular hole segment 101 away from the connecting rod 3 serves as the outlet for the liquid product; the ball-and-socket segment 102 is located at the end of the circular hole segment 101 near the connecting rod 3, and the shape of the ball-and-socket segment 102 matches the shape of the spherical cap segment 41; as Figure 4 As shown, the extension of the telescopic device 2 can drive the sealing head 4 to be inserted into the outlet 10, thereby causing the side wall of the cylindrical section 42 to fit against the side wall of the circular hole section 101, and causing the spherical crown section 41 to fit against the spherical socket section 102, thus closing the outlet 10; Figure 3As shown, the retraction of the telescopic device 2 can drive the sealing head 4 away from the liquid outlet 10, thereby separating the side wall of the cylindrical section 42 from the side wall of the circular hole section 101, and separating the spherical crown section 41 from the spherical socket section 102, thereby opening the liquid outlet 10.

[0025] In this embodiment, the sealing head 4 comprises two parts: a spherical crown section 41 and a cylindrical section 42. A telescopic device 2, via a connecting rod 3, drives the sealing head 4 to insert into or exit from the outlet 10, which has a corresponding shape. When the sealing head 4 is inserted into the outlet 10 under the drive of the telescopic device 2, not only will the sidewalls of the cylindrical section 42 and the circular hole section 101 be tightly pressed against each other, but the surfaces of the spherical crown section 41 and the spherical socket section 102 will also be tightly pressed against each other. Compared to existing technologies that achieve sealing only through simple cylindrical or conical surfaces, this embodiment significantly increases the contact area between the sealing head 4 and the outlet 10, thereby significantly increasing the length of the liquid product leakage path and improving the sealing performance between the sealing head 4 and the outlet 10. This allows the embodiment to achieve a good sealing effect without installing rubber components on the sealing head 4, thus avoiding problems such as dirt accumulation and rapid wear caused by rubber components. This embodiment achieves higher product quality and reduces maintenance cycles.

[0026] Furthermore, during the insertion of the sealing head 4 into the outlet 10, the cylindrical section 42 first passes through the ball-and-socket section 102 and then enters the circular hole section 101. On the one hand, the ball-and-socket section 102, which has a larger diameter than the cylindrical section 42, can provide guidance for the movement of the cylindrical section 42, thereby making the movement of the connecting rod 3 smoother. On the other hand, it will also make the effective flow cross-sectional area of ​​the outlet 10 decrease in a stepwise manner, thereby reducing the pressure change of the liquid product between the sealing head 4 and the outlet 10, making the reaction force changes of the sealing head 4, connecting rod 3 and telescopic device 2 more stable. This is conducive to achieving smoother and faster closing and opening actions in this embodiment, thereby improving the control accuracy of filling capacity and reducing the waste of liquid product.

[0027] In an optional embodiment, a connector 31 is provided at one end of the connecting rod 3 near the telescopic device 2. The connector 31 is used for detachable connection with the telescopic device 2. The specific structure of the connector 31 and the specific method of detachable connection are determined according to the model of the telescopic device 2, including but not limited to threaded connection, flange connection, snap-fit ​​connection or Y-type fork connection.

[0028] This embodiment allows workers to easily separate the connecting rod 3 and the telescopic device 2, so that the connecting rod 3 and the telescopic device 2 can be cleaned, maintained, or replaced regularly.

[0029] In an optional embodiment, a sealing ring 11 is also provided inside the potting tube 1. The outer side wall of the sealing ring 11 is connected to the inner side wall of the potting tube 1, and the inner side wall of the sealing ring 11 abuts against the outer side wall of the connecting rod 3. The specific structural form of the sealing ring 11 includes, but is not limited to, a metal sealing ring 11, a nylon sealing ring 11, or a polytetrafluoroethylene sealing ring 11.

[0030] This embodiment can separate the two ends of the filling tube 1 by means of the sealing ring 11. The end closer to the liquid outlet 10 is used for the flow of liquid products, and the end closer to and away from the liquid outlet 10 is used as the movement space of the telescopic device 2. This can prevent the telescopic device 2 from contaminating the liquid products and prevent the liquid products from interfering with the operation of the telescopic device 2. At the same time, the sealing ring 11 can also guide the movement of the connecting rod 3, thereby improving the smoothness of the movement of the connecting rod 3.

[0031] In an optional embodiment, the telescopic device 2 can be an existing product, and its specific form includes, but is not limited to, a hydraulic cylinder, a screw-type telescopic mechanism, an electric push rod, or a spring push rod.

[0032] In an optional embodiment, the telescopic device 2 includes a cylinder, which can improve the hygiene of the telescopic device 2 and reduce the risk of liquid products being contaminated by the telescopic device 2.

[0033] In an optional embodiment, the sealing head 4 and the connecting rod 3 are an integrated component.

[0034] This embodiment can eliminate the sanitary dead corner between the sealing head 4 and the connecting rod 3, thereby further reducing the risk of liquid products being contaminated due to dirt and grime accumulating in the sealing head 4 and the connecting rod 3.

[0035] In an optional embodiment, both the plugging head 4 and the connecting rod 3 are stainless steel components to reduce the risk of them being corroded by the liquid product and releasing contaminants, thereby contaminating the liquid product.

[0036] In an optional embodiment, the length of the cylindrical segment 42 along the axis of the connecting rod 3 is greater than the corresponding length of the circular hole segment 101, thereby making full use of the entire surface area of ​​the circular hole segment 101 to achieve a seal between the plug head 4 and the liquid outlet 10.

[0037] In an optional embodiment, the length of the spherical crown section 41 along the axis of the connecting rod 3 is greater than the corresponding length of the spherical socket section 102, thereby making full use of the entire surface area of ​​the spherical socket section 102 to achieve a seal between the sealing head 4 and the liquid outlet 10.

[0038] In an optional embodiment, the center of the spherical crown section 41, the axis of the cylindrical section 42, and the axis of the connecting rod 3 are all collinear, thereby preventing the load on the sealing head 4 from being eccentric relative to the connecting rod 3, which could lead to poor movement of the connecting rod 3, unbalanced force on the telescopic device 2, and increased risk of damage to the telescopic device 2.

[0039] In an optional embodiment, the end of the cylindrical segment 42 away from the connecting rod 3 is chamfered or rounded, thereby providing guidance for the insertion of the cylindrical segment 42 into the circular hole segment 101, so that the cylindrical segment 42 can be inserted into the circular hole segment 101 more smoothly.

[0040] Example 2 A filling machine includes a filling head as described in Example 1; while the other equipment of the filling machine, such as a bottle unscrambler and a feeding system, can be existing products.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
