How to adjust the filling volume of a paste filling machine?

2025-08-11

Hey there! As a supplier of paste filling machines, I've gotten tons of questions from customers about how to adjust the filling volume of these machines. It's a pretty common concern, and that's why I'm here today to share some tips and tricks with you.

First off, let's talk about why adjusting the filling volume is so important. Whether you're filling small jars or large containers, getting the right amount of paste in each one is crucial. Too little, and your customers might feel short - changed. Too much, and you're wasting product, which can eat into your profits. So, getting it just right is a win - win for everyone.

Understanding Your Paste Filling Machine

Before you start making any adjustments, it's super important to understand the type of paste filling machine you have. We offer a few different models, like the Automatic Desktop Paste Filling Machine, the Automatic 2 - head Paste Filling Machine, and the Automatic Rotor Pump Filler with Feeder. Each model has its own unique features and adjustment methods.

Most paste filling machines work based on a piston or a pump system. The piston - based machines use a piston to draw in and dispense the paste. The pump - based ones, on the other hand, use a pump to move the paste from the hopper to the container. Understanding how your machine works will give you a better idea of how to make the right adjustments.

Factors Affecting Filling Volume

There are several factors that can affect the filling volume of your paste filling machine. Let's take a look at some of the most common ones:

Viscosity of the Paste

The viscosity of the paste is a major factor. Thicker pastes are harder to move through the machine, and they might require more pressure or a slower filling speed. If the paste is too thick, it might not fill the container completely, or it could cause the machine to jam. On the other hand, thinner pastes can flow more easily, but they might also spill or overfill if not adjusted properly.

Nozzle Size

The size of the nozzle also plays a big role. A larger nozzle will allow more paste to flow through, resulting in a larger filling volume. A smaller nozzle, on the contrary, will restrict the flow and give you a smaller filling volume. You might need to experiment with different nozzle sizes to find the one that works best for your product.

Machine Speed

The speed at which the machine operates can affect the filling volume. If the machine is running too fast, the paste might not have enough time to fill the container properly. If it's running too slow, it could lead to overfilling. You'll need to find the optimal speed for your specific product and machine.

Adjusting the Filling Volume

Now that we've covered the basics, let's get into how you can actually adjust the filling volume of your paste filling machine.

Piston - Based Machines

If you have a piston - based paste filling machine, the first thing you can do is adjust the stroke length of the piston. The stroke length determines how much paste the piston draws in and dispenses. Most machines have a mechanical or electronic adjustment mechanism for the stroke length. You can usually find a dial or a control panel where you can increase or decrease the stroke length.

Another way to adjust the filling volume is by changing the speed of the piston. A slower piston speed will give the paste more time to fill the container, resulting in a more accurate filling volume. You can adjust the piston speed through the machine's control panel.

Pump - Based Machines

For pump - based paste filling machines, you can adjust the pump speed. Increasing the pump speed will increase the flow rate of the paste, resulting in a larger filling volume. Decreasing the pump speed will do the opposite. You can usually find a speed control on the machine's control panel.

You can also adjust the pressure of the pump. Higher pressure will force more paste through the nozzle, increasing the filling volume. Lower pressure will reduce the filling volume. However, be careful not to set the pressure too high, as it could damage the machine or cause the paste to splash.

Step - by - Step Adjustment Process

Here's a step - by - step process to help you adjust the filling volume of your paste filling machine:

Prepare Your Machine: Make sure the machine is clean and in good working condition. Fill the hopper with the paste you want to fill.
Set the Initial Parameters: Based on the type of machine you have, set the initial stroke length, pump speed, or pressure. You can start with the manufacturer's recommended settings.
Run a Test Cycle: Start the machine and run a few test cycles with empty containers. Measure the filling volume of each container using a measuring cup or a scale.
Make Adjustments: If the filling volume is too small, increase the stroke length, pump speed, or pressure. If it's too large, decrease these parameters. Make small adjustments at a time and run another test cycle after each adjustment.
Repeat the Process: Keep repeating the test - and - adjust process until you get the desired filling volume. Make sure to test multiple containers to ensure consistency.

Troubleshooting Common Issues

Sometimes, you might run into some issues when adjusting the filling volume. Here are some common problems and how to fix them:

Inconsistent Filling Volume

If you're getting inconsistent filling volumes, it could be due to air bubbles in the paste. Try to remove the air bubbles by stirring the paste gently or using a degassing device. It could also be a problem with the machine's seals or valves. Check these components for any signs of wear or damage and replace them if necessary.

Overfilling or Underfilling

If the machine is overfilling or underfilling consistently, it could be a calibration issue. Make sure the machine is properly calibrated according to the manufacturer's instructions. You might also need to check the nozzle for any blockages or damage.

Conclusion

Adjusting the filling volume of a paste filling machine might seem a bit tricky at first, but with a little patience and some experimentation, you can get it just right. Remember to understand your machine, consider the factors that affect filling volume, and follow the step - by - step adjustment process.
