Description

Technical Field

[0001] This utility model relates to the field of filling head technology, specifically a filling head. Background Technology

[0002] In the filling process of various liquid or semi-fluid materials, the filling head is a core component, and its performance directly affects the filling efficiency and product quality. Traditional filling heads usually consist of a filling head body and a bottom discharge pipe. The material is discharged through the discharge pipe to complete the filling operation. However, in some scenarios with high requirements for filling accuracy and material conveying stability, relying solely on the discharge pipe for material conveying has certain limitations. For example, when the opening of the filling container is small, it is necessary to replace it with a corresponding filling head to meet the filling requirements of the small opening, which affects the filling quality and production efficiency. Therefore, it is necessary to improve the structure of the filling head to improve its filling efficiency. To solve the above problems, we propose a filling head. Utility Model Content

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This filling head features a rubber discharge pipe and mounting pipe arranged around the outer ring of the discharge pipe.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1-5 A filling head includes a filling head body 1. A discharge pipe 7 is installed at the bottom of the filling head body 1. A rubber discharge pipe 5 is sleeved around the outer ring of the discharge pipe 7. An installation pipe 6 is sleeved around the upper outer ring of the rubber discharge pipe 5 at the outer ring of the discharge pipe 7. The installation pipe 6 and the rubber discharge pipe 5 are fixed to the discharge pipe 7 by a clamp 2 to make their connection secure. Multiple through slots are evenly opened at the lower part of the installation pipe 6. A fan-shaped hinge plate 3 is hinged to the inner wall of the top of each through slot. Limiting plates 4 are welded to the outer walls of the multiple hinge plates 3. Through holes are opened on the limiting plates 4, and cable ties 9 are passed through the multiple limiting plates in sequence. The cable tie 9 has a through hole at one end and a cable tie head 8 at the other end. A through hole is provided on one side of the cable tie head 8 so that the cable tie 9 can pass through. An installation groove is provided on one side of the through hole, and a locking tooth 10 is installed in the installation groove. Multiple sets of teeth provided in the middle of the outer ring of the cable tie 9 match the locking tooth 10. When it is necessary to fix the rubber discharge tube 5, the cable tie 9 is pulled through the cable tie head 8 to tighten the cable tie 9. The teeth and locking tooth 10 mesh with each other, so that the lower part of the hinge plate 3 can move inward, which can make the discharge port of the rubber discharge tube 5 smaller, making it easier to pour the material into a container with a smaller opening, preventing material leakage and waste.

[0021] Example 2: Please refer to Figures 1-5 Based on Embodiment 1, the structure of the cable tie head 8 is further optimized. A movable extrusion plate 13 is positioned between the teeth and locking teeth 10 within the through hole of the cable tie head 8. The height of the extrusion plate 13 is equal to the height of the cable tie 9, and one side extends to the outside of the cable tie head 8. A pressing plate 12 is provided at one end located outside the cable tie head 8. Multiple rubber extrusion rods 11 are installed on the side of the pressing plate 12 that is close to the cable tie head 8. The multiple extrusion rods 11 are respectively installed on the upper part of the pressing plate 12 located on both sides of the extrusion plate 13. At the bottom, when it is necessary to loosen the cable tie 9 to adjust the size of the outlet of the rubber discharge tube 5, the pressing plate 12 can be pressed towards the cable tie head 8. The extrusion rod 11 is deformed by the extrusion, and the pressing plate 12 can drive the extrusion plate 13 to move towards the cable tie 9. The extrusion plate 13 separates the teeth of the cable tie 9 from the locking teeth 10. At this time, the cable tie 9 can be easily pulled to adjust its tightness. After the adjustment is completed, the pressing plate 12 is released, the extrusion rod 11 returns to its original state, the extrusion plate 13 no longer extrudes the cable tie 9, and the cable tie 9 can be fixed again by the teeth and locking teeth 10.

[0022] Example 3: Please refer to Figures 1-5 The filling head in this embodiment also includes a filling head body 1, a discharge pipe 7, a rubber discharge pipe 5, an installation pipe 6, and other components. The rubber discharge pipe 5 and the installation pipe 6 are fixed to the discharge pipe 7 by a clamp 2. The lower part of the installation pipe 6 has multiple through slots and is hinged to a fan-shaped hinge plate 3. A limiting plate 4 with through holes is welded to the outside of the hinge plate 3. The cable tie 9 passes through the through hole of the limiting plate 4 and has a cable tie head 8 at one end. The structural design of the cable tie head 8 is the same as in embodiment two, and it has locking teeth 10, a pressing plate 13, a pressing plate 12, and a pressing mechanism. In practical applications, when filling different container openings, the tension of the cable tie 9 can be adjusted by operating the pressing plate 12. For example, for containers with smaller openings, the cable tie 9 can be tightened appropriately to reduce the discharge port of the rubber discharge tube 5 and prevent material leakage. For containers with larger openings, the cable tie 9 can be loosened appropriately to ensure that the material can flow out smoothly and quickly. This adjustable fixing method allows the filling head to adapt to the filling needs of containers with different diameters, improving the flexibility and versatility of filling production.

[0023] Implementation Results: By setting a rubber discharge pipe 5 and an installation pipe 6 around the outer ring of the discharge pipe 7, and fixing them by passing the cable ties 9 through the through holes of the external limiting plates 4 of the multiple hinge plates 3, the size of the material discharged from the outlet of the rubber discharge pipe 5 can be effectively controlled. The teeth in the middle of the outer ring of the cable tie 9 match the locking teeth 10 inside the cable tie head 8. When the cable tie 9 is tightened, the teeth and locking teeth 10 mesh together, which can firmly fix the discharge diameter of the outlet of the rubber discharge pipe 5, preventing material leakage and waste during the filling process. At the same time, this method of fixing by the cable tie 9 is easy to operate, and the tightness of the cable tie 9 can be flexibly adjusted according to actual needs to adapt to the material filling of different container opening requirements, thus improving the adaptability of the filling head to containers of different diameters.
