Shilong Machinery Shares About Semi-Automatic Paste Filling Machine Today

Full Introduction to Semi-Automatic Paste Filling Machine

1. Basic Definition

A semi-automatic paste filling machine is a quantitative filling device where operators place empty bottles under the filling nozzle, the machine automatically completes quantitative filling, and workers remove filled containers afterward. It is designed for flexible small and medium-batch multi-product production, suitable for high-viscosity pastes, sauces and semi-fluid materials. Pneumatic piston type is the mainstream model, with servo electric, screw and weighing types as alternative options.

2. Core Working Principle (Mainstream Piston Type)

Operators place containers below the filling nozzle;

Step on the foot pedal or press the button, the air cylinder pulls the piston backward to suck paste into the hopper;

The piston pushes forward to extrude materials for quantitative filling;

The machine automatically stops feeding once the preset volume is reached, and the anti-drip nozzle cuts off residual materials, then workers take away finished products;

Adjust the stroke of the air cylinder to freely change filling volume, and the filling speed is adjustable.

3. Machine Structure (Food-Grade 304 Stainless Steel)

Material Storage Hopper: Conical type for ordinary pastes; U-shaped with agitator for precipitable and high-viscosity sauces, heating & thermal insulation function is optional;

Metering Piston Cylinder & Rotary Valve: Core quantitative components, quick disassembly for easy cleaning;

Pneumatic / Servo Driving System: Pneumatic version requires an air compressor; servo version works simply by powering on;

Anti-Drip Filling Nozzle: Prevent wire drawing and material dripping;

Control Components: Foot switch, pressure regulating valve, volume adjusting handle, touch screen (high-end configuration);

Frame: Tabletop or floor-standing vertical design, small floor space occupation.

4. Comparison of Three Mainstream Models

1. Pneumatic Piston Type (Best-Selling on the Market)

Power Supply: Driven by air compressor, no high voltage on the whole machine, explosion-proof available;

Filling Accuracy: ±0.5%~±1%;

Price Range: 12,000 – 35,000 RMB;

Advantages: Simple structure, low failure rate, easy cleaning, applicable for explosion-proof workshops;

Disadvantages: Supporting air compressor is required, slight air pressure fluctuation may affect filling accuracy;

Application: Face cream, ointment, chili sauce, honey, gel.

2. Servo Electric Piston Type (High Precision Version)

Power Supply: Servo motor driven, no air compressor needed;

Filling Accuracy: ±0.3%~±0.8%, stable performance without fluctuation;

Price Range: 25,000 – 60,000 RMB;

Advantages: Volume adjustment via touch screen, dual-speed filling, low noise, stable metering;

Application: Cosmetics, medicinal ointments, high-end sauces, small-specification pastes.

Servo Touch Screen Model

3. Integrated Machine with Stirring & Heating Function (For High-Viscosity Prone-to-Precipitation Materials)

Built-in stirring paddles and thermal insulation interlayer inside the hopper. Ideal for peanut butter, chocolate sauce, herbal paste and hot-melt pastes to avoid stratification and caking; constant temperature heating can be customized.
