The blister machine is widely used in the plastics industry. As a thermoforming equipment with low investment and wide application, its work flow is simple, easy to operate and maintain. As a mechanical equipment, it is inevitable that some small failures will occur during processing and operation. The vacuum system is the core of a blister machine, so how to solve it when there is no vacuum? Based on years of experience of masters operating machinery and equipment, the editor summarizes the following:


First, find out the reason, and check from four places of the blister machine: air circuit, solenoid valve, vacuum pump motor belt, vacuum meter, and then you can deal with the problem according to the inspection situation of the blister machine. The common situations are: The air path of the blister machine is blocked, the solenoid valve is open, the vacuum pump motor belt of the blister machine is not tight, and the vacuum meter of the blister machine is useless.


If these problems are not solved, the operation of the blister machine will be unstable and defective products will be easily produced. For example: the position is not accurate when sucking the film; the blister machine does not start sucking and covering, the film will automatically pull down and other problems, the solution:

1. Keep the air path of the blister machine unobstructed; 2. Close the solenoid valve of the blister machine; 3. The vacuum pump motor belt of the blister machine should be tightened back. If it does not work, it needs to be replaced; 4. Replace the blister machine Installed on a high-quality vacuum gauge.


The above is just a treatment method for the vacuum not to rise when the blister machine is working. It is inevitable that small problems will occur when the blister machine works for a long time, and it is not a quality problem. Moreover, each problem is well-documented, and it is important to investigate it in time, and it is not difficult to deal with it.

Before the blister machine is used, when it is used, and after it is used, if the operator has completed the three points of comprehensive inspection, correct operation and maintenance of the blister machine, it will not only ensure the more efficient work of the blister machine , Can also greatly reduce maintenance costs.
