Product Introduction
The semi-automatic pneumatic paste liquid filling machine is our latest developed paste and liquid filling equipment. This type of equipment is a product that has undergone in-depth transformation and innovative upgrading based on advanced filling machine technology at home and abroad. It features a brand new horizontal flat design and is lightweight and convenient. The equipment adopts pneumatic components (cylinders) and piston type push-pull rod structure. Due to the formation of a vacuum chamber in the material cylinder during operation, negative pressure can be used to suction materials. So it is possible to fill viscous and poorly flowing materials.

scope of application
Various viscosity products ranging from water-based agents to cream formulations are widely used in daily chemical products, cream formulations, shampoos, pharmaceuticals, food, and edible oils.
The ideal filling machine for industries such as pesticides is suitable for filling pastes and viscous substances.

Product Features
This machine is controlled and driven by compressed air, making it particularly suitable for use in environments with explosion-proof requirements and humidity, with high safety
Due to the use of pneumatic control and mechanical positioning, the filling accuracy is high and can be controlled within ± 1%
Using a screw rod and counter, the filling volume can be adjusted accurately and can be intuitively reflected in digital form
According to actual needs, it can be freely switched between "manual" and "automatic" filling states
The equipment failure rate is extremely low

Malfunctions and Maintenance
1. After turning on, the crankshaft cannot rotate normally. Fault:
A： The upper fixing rod is biased downwards, and the inner and outer tubes of the syringe are firmly pressed when pushing the liquid, causing the crank to not rotate. The nut ① should be loosened, and the upper fixing rod should be moved up to the appropriate position before tightening the nut.
B： During the assembly of the syringe, the inner and outer tubes may get stuck due to uncleanliness, and the syringe needs to be removed for cleaning.
C： The injection system is not installed in the bearing area. Make it unable to function properly, it must be reinstalled.
2. The injection is uneven, the joint is not tightened properly, and there is air leakage. Further tightening is required.
3. The machine rotates normally, but no dispensing fluid is discharged. Fault:
A： There are foreign objects inside the valve that need to be cleaned;
B： The upper and lower pins inside the valve are placed incorrectly (both pins have their tips facing downwards and must not be installed backwards).
C: When there is liquid leakage from the outlet at the lower end of the piston in the 100 and 500ml models, the cylinder should be disassembled and replaced with a random sealing ring. Note: The sealing ring should use a φ 65 × 3.1 acid and alkali resistant sealing ring.
