Working Principle
Piston-type Filling Principle: The piston is driven by the air cylinder to make reciprocating motion in the cylinder barrel. When the piston moves backward, the hair clay material enters the piston cylinder through the feed inlet under the action of atmospheric pressure. When the piston moves forward, the hair clay in the cylinder is extruded and filled into the container through the discharge outlet. The filling volume can be controlled by adjusting the stroke of the piston. For example, some semi-automatic piston-type hair clay filling machines adopt this method, which has a simple structure and is easy to operate.
Screw Pump Filling Principle: The rotation of the screw is used to convey the hair clay material. When the screw rotates in the pump body, a sealed space is formed to convey the hair clay from the feed inlet to the discharge outlet, realizing quantitative filling. The rotation speed of the screw pump is directly proportional to the filling volume. By controlling the rotation speed of the motor, the rotation speed of the screw can be accurately controlled, so as to achieve the purpose of accurately controlling the filling volume. This principle is often used in hair clay filling production lines with high requirements for filling accuracy.
Structural Composition
Material Storage and Conveying System: It includes the hopper, conveying pipeline, etc. The hopper is used to store the hair clay material, and the conveying pipeline conveys the material from the hopper to the filling head. The hoppers of some filling machines are also equipped with a stirring device to prevent the hair clay from settling or caking in the hopper and ensure the uniform conveying of the material.
Filling System: It is the core part of the hair clay filling machine, mainly composed of the filling head, metering device, etc. The filling head is responsible for accurately injecting the hair clay into the container, and the metering device controls the amount of each filling. The common metering methods include volumetric metering and weighing metering.
Container Conveying and Positioning System: It is used to convey the containers to be filled and accurately position them under the filling head. It is usually composed of a conveyor belt, transmission device, positioning device, etc. The conveyor belt conveys the containers from the feed inlet to the filling position, and the positioning device ensures that the containers remain stable during the filling process to avoid filling deviation.
Control System: Generally, it is controlled by combining a PLC (Programmable Logic Controller) with a touch screen. Operators can set parameters such as the filling volume, filling speed, and container specifications through the touch screen. The PLC controls the operation of each component according to the set parameters to realize the automatic filling process. It also has functions such as fault alarm and diagnosis, which is convenient for operators to find and solve problems in a timely manner.
Types
Semi-automatic Hair Clay Filling Machine: Manual operations such as bottle loading and unloading are required, but the filling process is automatically completed by the machine. Its structure is relatively simple, and the price is relatively low. It is suitable for small and medium-sized hair clay production enterprises or workshops. For example, the ZH-DW single-head horizontal paste filling machine is easy to operate, has high filling accuracy, and can be customized according to customer requirements.
Fully Automatic Hair Clay Filling Machine: A series of processes from container conveying, positioning, filling to capping and labeling can be automatically completed. It has high production efficiency and accurate filling accuracy, which can effectively reduce labor costs and the influence of human factors on product quality. It is suitable for large-scale hair clay production enterprises. For example, some fully automatic hair clay filling production lines that adopt the screw pump filling principle can achieve high-speed and high-precision filling.
Features
High-precision Filling: By adopting advanced metering devices and filling technologies, it can ensure that the filling volume of each bottle of hair clay is accurate and consistent. The filling accuracy can be controlled within ±1%, reducing material waste and ensuring the stability of product quality.
High-efficiency Production: The production speed of the fully automatic hair clay filling machine is relatively fast, and it can fill dozens or even hundreds of bottles per minute, greatly improving production efficiency and meeting the needs of large-scale production of enterprises.
Strong Adaptability: It can be adjusted according to different container specifications and the characteristics of hair clay products. After replacing the filling head and related components, it can adapt to the filling of hair clay in various bottle shapes and capacities, and can also handle hair clay materials with different viscosities.
Hygiene and Safety: The parts in contact with the material are usually made of materials such as 304 stainless steel or 316L stainless steel that meet food hygiene standards. The surface is smooth and easy to clean, avoiding the contamination of the hair clay. At the same time, the equipment is also equipped with protective devices to ensure the safety of operators.
Application Fields
Daily Chemical Product Production: It is mainly applied to hair clay manufacturers and is used to fill hair clay into various packaging containers such as plastic bottles and hoses to meet market demand.
Beauty and Hairdressing Industry: Some professional beauty and hairdressing institutions or product customization enterprises will also use small hair clay filling machines to customize personalized hair clay products to meet the needs of different customers.
