Working Principle:

The working principle of the sealing machine involves the following steps:

 

1. Pressing the start switch activates the main motor, which, in turn, drives the electric heating unit cam group, tension cam, and three cam pieces located on the side of the reducer.

2. The three cam pieces (A, B, C) correspond to three induction switches and control the position of the electric heating unit and the overall movement of the binding process.

3. The limit switch B controls the unwinding and second tightening of the shrinking arm during the strapping process. When the cam plate contacts induction switch B, the electric heating unit stops, and the forward and retreat motor initiates the tightening and unwinding of the strapping. 

The upper top knife rises, causing the middle top knife at the bottom of the skateboard to press against the strapping belt and cut it. Simultaneously, the belt guide device moves backward, fully opening the left belt tongue.

4. When the cam piece contacts the limit switch C, the forward and retreat belt motor starts, feeding the strapping belt into the belt path and bow frame.

If the belt storage box has a small balance bar, it will be lifted, and the induction switch at the base of the balance bar will activate, starting the belt feed motor of the storage box.

5. The function of the limit switch A is to control the entire strapping process.
When the cam plate contacts it, the main motor stops running, and the electromagnetic clutch engages.
At the same time, the forward and backward belt motor and the storage box motor also stop running.

 

Failure and Handling:

The article does not provide specific information about failure and handling procedures. It would be helpful to include details about common failures and their corresponding troubleshooting steps.

Malfunction the reason Solution
Cassette When the belt is stuck in the middle of the roller, or there is a foreign object that cannot be removed Loosen the two M5 cassette countersunk screws on the middle connecting shaft and remove the connecting shaft,
Pick up the upper wheel and remove the jam
Do not cut the tape after tightening The elastic adjustment is too tight;
Cutter wear
Adjust the tension dial to loosen the tension;
Replace the cutter
Do not bring Do not cut the tape after tightening;
Incorrect wear;
The belt of the feed motor is damaged or
The fixing screw of the pulley is loose;
Re-install;
Re-thread
Replace the pulley and tighten the fixing screws;
Bad bonding of strapping Displacement of the belt groove;
The electric heating head is broken;
The temperature of the heating head is too high or too low;
Re-adjust the belt groove;
Replace the electric heating head;
Correctly adjust the temperature of the heating head;

The above is the working principle of the automatic strapping machine, faults and solutions.
