The following is a relevant introduction to the shampoo filling machine:

Working Principles

• Piston - type Filling Principle: Pour the shampoo into the material cylinder through the feed port on the filling head. Then, use the movement of the piston to push the shampoo out of the material cylinder, and make it flow into the bottle through the anti - drip device. The filling volume can be controlled by adjusting the filling volume control valve and the stroke of the stepper motor, enabling relatively precise filling.

• Atmospheric Pressure Filling Principle: Under normal atmospheric pressure, relying on the gravity of the liquid itself, the shampoo flows from the liquid storage tank through the pipeline and filling head into the container to be filled. This method is suitable for shampoos with good fluidity, has a relatively simple structure, and operates stably.

• Negative Pressure Filling Principle: First, evacuate the filling container to create a negative pressure inside the container. Then, the shampoo is sucked into the container under the action of atmospheric pressure. Negative - pressure filling can effectively prevent the formation of foam during the shampoo filling process, and is suitable for some shampoo products that are prone to foaming.

Structural Composition

• Feeding System: Mainly includes components such as the liquid storage tank, feed pipeline, and valves. The liquid storage tank is used to store the shampoo to be filled. The feed pipeline connects the liquid storage tank with the filling head, and the valves are used to control the flow direction and flow rate of the shampoo.

• Filling System: It is the core part of the filling machine and is usually composed of components such as the filling head, piston, and metering device. The filling head is responsible for accurately injecting the shampoo into the packaging container. The piston moves back and forth driven by power to achieve the extraction and pushing of the shampoo. The metering device is used to precisely control the amount of shampoo filled each time.

• Transmission System: Generally composed of components such as the motor, reducer, and conveyor belt. The motor provides power. The reducer converts the high - speed rotation of the motor into a low - speed rotation suitable for the operation of the filling machine, and the conveyor belt transports the packaging containers to each station to achieve continuous filling operations.

• Control System: It mostly adopts microcomputer PLC automatic control technology, equipped with a human - machine interface touch screen, which can realize functions such as parameter setting, operation status monitoring, and fault alarm of the filling machine.

Classification

• Classification by Degree of Automation: There are manual filling machines, such as hand - pressed filling machines. They have a relatively low price and simple operation, but low production efficiency, and are suitable for small - batch production. Semi - automatic filling machines require manual assistance to complete some processes, such as bottle feeding and bottle discharging. Their production efficiency and degree of automation are average. Fully automatic filling machines can automatically complete a series of processes such as bottle feeding, filling, and bottle discharging, with high production efficiency and high filling accuracy, suitable for large - scale production.

• Classification by the Number of Filling Heads: There are single - head filling machines, which have a simple structure and low price, but relatively low production efficiency. Multi - head filling machines, such as 6 - head and 12 - head ones, can fill multiple packaging containers simultaneously, greatly improving production efficiency and being suitable for production requirements with large output.

Features

• High - precision Measurement: Adopting advanced metering devices and control systems, it can accurately control the filling volume of shampoo. The filling accuracy can reach ±0.5% or even higher, ensuring that the capacity of each bottle of shampoo meets the standard requirements.

• Wide Application Range: It is not only suitable for shampoo filling but also for the filling of various daily chemical products such as hair conditioners, body washes, facial cleansers, and fabric softeners. Moreover, it can adapt to packaging containers of different shapes and specifications, such as round barrels and square barrels.

• High Hygiene Standards: All components in contact with the materials are made of high - quality stainless steel, meeting the requirements of GMP standards, ensuring that the shampoo is not contaminated during the filling process and guaranteeing product quality and safety.

• Simple Operation and Maintenance: The operation interface of the equipment is simple and easy to understand. After simple training, the staff can operate it skillfully. At the same time, the liquid cylinder and its pipelines are easy to disassemble and clean, facilitating daily maintenance and reducing the equipment downtime, thereby improving production efficiency.

Purchase Considerations

• Production Capacity: According to one's own production scale and output requirements, select a filling machine with an appropriate production capacity, such as how many bottles or liters can be filled per hour, to ensure that the production task can be met.

• Filling Accuracy: For products like shampoo that require high capacity accuracy, choose a filling machine with high filling accuracy. Generally, the filling accuracy should be controlled within ±1% to avoid quality problems and cost increases caused by capacity differences.

• Applicable Bottle Types: Confirm that the filling machine can adapt to the shape, size, and material of the packaging containers used, including parameters such as bottle height, bottle diameter, and bottle mouth diameter, to ensure the smooth progress of the filling process.
