Description

Technical Field

[0001] This utility model relates to the field of single-head quantitative filling machine technology, and in particular to a single-head quantitative filling machine with automatic cleaning function. Background Technology

[0002] In mixed dye filling production lines, single-head quantitative filling machines play a crucial role in filling accuracy and production efficiency. To achieve high-precision, rapid filling of liquid materials, a dedicated quantitative control system is typically required. This system usually includes core functional modules such as flow metering, valve control, and container positioning. Especially during mixed dye filling processes, with fluctuations in flow rate and the risk of leakage, the metering accuracy and valve response speed of the equipment directly affect product qualification rate and production line efficiency. Therefore, developing a high-precision, highly stable, and adaptable single-head quantitative filling machine has become an important direction for equipment upgrades.

[0003] In existing technologies, single-head filling machines used for quantitative liquid filling generally include a metering pump, a filling valve, and a container positioning mechanism. Structurally, the equipment uses a flow sensor or weighing module for quantitative control and a solenoid valve or pneumatic valve to switch the filling process on and off. It is also equipped with a conveyor belt or clamp positioning device to ensure accurate container alignment. In practical use, the sealing cap of the filling head is usually fixedly connected to the machine body, making it difficult to open quickly when adding or changing dye; multiple fasteners must be removed. Furthermore, the cleaning and maintenance channels for the filling valve are narrow, making operation inconvenient and impacting production efficiency.

[0004] However, existing single-head quantitative filling machines still have certain problems in practical applications. Because mixed dyes need to be added repeatedly, the traditional can lids are mostly fixed with screws or similar fasteners, making them difficult to open quickly and easily, affecting work efficiency, accuracy, and causing contamination between raw materials. Therefore, a single-head quantitative filling machine with an automatic cleaning function is proposed to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a single-head quantitative filling machine with automatic cleaning function, which aims to improve the problem that the locking cap cannot be opened quickly when the single-head quantitative filling machine is working in the prior art.

One end of the spring is fixedly connected to the bottom of the push post, and the other end of the spring is fixedly connected to the top of the upper connecting block. A shrinkage groove is formed inside the upper connecting block, and a sliding groove is formed inside the lower connecting block.

This solves the problem that the single-head quantitative filling machine cannot quickly open the locking can lid during operation, and improves the convenience of the single-head quantitative filling machine.
