The design employs a waterproof proximity switch, a moving rod, and a float structure, along with a screw and an adjusting plate. The float senses the approach of the filling tube and automatically stops the filling process. The screw, driven by a motor, adjusts the height of the placement plate to regulate the distance between the container and the filling tube.
It enables precise control of the filling volume, avoiding overfilling or underfilling, and improving the accuracy and quality of filling.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of filling device technology, specifically a filling device for preparing printing ink. Background Technology
[0002] Printing ink is a homogeneous mixture composed of colored substances (such as pigments and dyes), binders, fillers, and additives. It is printable and dries on the printed surface. After preparation, printing ink can be filled using a filling device. However, in existing technologies, the containers used to hold the ink are made of opaque material to prevent oxidation. While this effectively protects the ink, it makes it difficult to control the filling volume, leading to overfilling or underfilling, affecting filling quality. Furthermore, different container capacities result in varying distances between the filling tube and the container's filling opening; excessively large distances can lead to inaccurate filling and inconvenience. Therefore, improvements to the existing technology are needed. Utility Model Content

[0007] Preferably, a guide tube is fixedly connected to the upper end of the crossbar, and the guide tube is slidably connected to the moving rod. The guide tube can increase the stability of the moving rod.
[0008] Preferably, the adjusting mechanism includes a screw, which is mounted inside the base via a bearing. An adjusting plate is slidably connected inside the base, and an internally threaded tube is fixedly connected inside the adjusting plate. A support frame is fixedly installed inside the base. A first bevel gear is fixedly connected to the lower outer side of the screw. A motor is fixedly installed at the lower end of the base. A second bevel gear is fixedly connected to the outer side of the motor's output shaft. A reinforcing rib is fixedly connected to the lower end of the placement plate. The screw can adjust the position of the placement plate by driving the adjusting plate through the threaded engagement with the internally threaded tube.
[0009] Preferably, the support frame is connected to the screw via a bearing, and the screw is connected to the internally threaded tube via a thread. The support frame can support the screw, making the screw more stable.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model incorporates a waterproof proximity switch, a moving rod, and a float inside the filling tube. During use, the filling tube is inserted into the packaging container. When the container is nearly full, the float moves the moving rod up and down using buoyancy. When the moving rod contacts the waterproof proximity switch, the filling stops, thus effectively preventing filling filtration or insufficient filling.
[0013] 2. This utility model adds a placement plate, an adjustment plate, and a screw to the base. During use, the screw is driven by a motor to rotate. During the rotation of the screw, the screw can move the adjustment plate and the placement plate through the threaded engagement with the internal threaded tube. Thus, the distance between the container and the filling tube can be controlled by adjusting the height of the placement plate, which can improve the filling quality. Attached Figure Description

[0023] Please see Figure 1 , Figure 2 , Figure 5 The adjusting mechanism 3 includes a screw 31. The screw 31 is mounted inside the base 1 via a bearing. An adjusting plate 32 is slidably connected inside the base 1. An internally threaded tube 33 is fixedly connected inside the adjusting plate 32. A support frame 34 is fixedly installed inside the base 1. A bevel gear 35 is fixedly connected to the lower outer side of the screw 31. A motor 36 is fixedly installed at the lower end of the base 1. A bevel gear 37 is fixedly connected to the outer side of the output shaft of the motor 36.

While the moving rod 11 moves, it compresses the spring 13 through the retaining ring 12. When the moving rod 11 contacts the waterproof proximity switch 9, the filling can be stopped, thereby effectively controlling the filling amount.
