Description

Technical Field

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

[0002] In the filling process, a filling head is used to fill the bottle with liquid. For conventional filling devices, the bottom of the filling head is aligned with the bottle neck before filling. This filling method is prone to dripping because current filling structures and traditional filling methods spray directly from the outlet into the bottle. After a portion of the liquid has been filled, the spraying continues. Due to the high pressure, the liquid is pushed back towards the bottle neck and even outside the bottle. The liquid easily drips out from the contact point between the bottom of the filling head and the bottle neck, causing not only contamination but also waste. Utility Model Content

[0003] The purpose of this utility model is to solve the problems mentioned in the background art. This utility model provides a filling head with a redesigned filling structure to avoid dripping during filling.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] The filling head includes a filling head body, the top of which is connected to a cylinder, and the bottom of the filling head body is connected to a discharge block. The discharge block passes through an outer valve body, the top of which is connected to the bottom of a spring. The top of the spring is mounted on the filling head body. The filling head body is provided with a feeding channel, and the discharge block is provided with a discharge port, which is connected to the feeding channel.

[0006] Furthermore, the feeding channel includes feeding channel one and feeding channel two, which are connected. Feeding channel one is perpendicular to the discharge block, and the top of the discharge block is installed in feeding channel two.

[0007] Furthermore, the feed channel 2 is provided with internal threads, and the discharge block is provided with external threads, and the discharge block is threadedly connected to the feed channel 2.

[0008] Furthermore, the main body of the filling head includes a cylinder connection part and a discharge block connection part. The output end of the cylinder is connected to the top middle of the cylinder connection part. The upper parts of the first feeding channel and the second feeding channel are located inside the cylinder connection part, and the lower part of the second feeding channel passes through the middle of the discharge connection part.

[0009] Furthermore, the discharge block connection part has a stepped structure, including an upper discharge connection part and a lower discharge connection part. The diameter of the upper discharge connection part is larger than the diameter of the lower discharge connection part. The upper discharge connection part is connected to the bottom of the cylinder connection part, and the top of the spring is installed at the upper discharge connection part.

[0010] Furthermore, the top of the outer valve body is provided with a spring mounting groove, the bottom of the spring is installed in the spring mounting groove, the bottom of the outer valve body is provided with a second groove, and the upper end of the second groove is provided with several circumferentially distributed slots.

[0011] Furthermore, the discharge block includes a discharge block connecting part and a discharge block body. The discharge block body passes through the outer valve body, and the external thread is set at the circumference of the discharge block connecting part. The outer diameter of the discharge block body is larger than the inner diameter of the feed channel two. A sealing ring one installation groove is provided at the connection between the discharge block connecting part and the discharge block body, and a sealing ring one is installed at the sealing ring one installation groove.

[0012] Beneficial effects:

[0013] During filling, the outer valve body presses against the bottle mouth, the cylinder operates, and the cylinder drives the filling head body to move. The filling head body moves the discharge block towards the bottle mouth. When the filling head body contacts the outer valve body, the filling head body can no longer move, and filling begins. After filling is completed, the cylinder operates, the spring returns to its original position, and the filling head body and the discharge block separate. Throughout the filling process, the inner wall of the bottle is not subjected to significant impact, preventing leakage. Attached Figure Description
