Malfunction repair of the glue machine
1. The motor rotates but cannot be heated.
Usually it is a relay fault, which can be judged by measuring whether there is 220V voltage at both ends of RL. If there is no voltage or the voltage is too low, the relay is not sucked or the suction is poor. Most of the relay K is damaged or the contact is ablated. The relay should be replaced or the sanded contact should be removed.
2. Can not be heated.
Since the thermistor is in contact with the surface of the pressing shaft, the friction is generated by the rotation of the pressing shaft, and will be detached, loosened or damaged over time, and should be re-fixed to the original position and brought into good contact with the pressing shaft surface. If damaged, replace the new thermistor.
3. The noise is large.
Since the machine is operated at high temperatures for a long time, the lubricating oil of each transmission gear is easily dried, resulting in a large noise. After refilling, you can troubleshoot.
Common classification
1. Temperature-regulating type glue machine: This feature is that the pressure and speed have been fixed. The temperature is adjustable. The pressure between the rubber rollers and the running speed of the rubber roller are fixed at the factory, and the plastic sealing temperature can be adjusted by the user. The sealing fastness of the document is controlled by the plastic sealing temperature. Since the structure of the laminator varies from manufacturer to manufacturer, the temperature displayed on the laminator is not necessarily equal to the laminating temperature. Generally, a laminator heated by a front rubber roller is used, and the display temperature is close to the plastic sealing temperature. The operation of this type of machine should be carried out one by one according to the procedures required by the process. When the pressure and speed are constant, the temperature is too low and the plastic seal is not strong. When the temperature is too high, deformation and overflowing occur. If the pressure between the rubber rollers is too large, it is easy to overflow. If the temperature is repeatedly adjusted and still can not meet the plastic sealing requirements, the pressure of the model has a certain adjustable range. Refer to the product description to unload the cover and make appropriate fine adjustment to meet the optimal plastic sealing conditions.
2, speed control type of glue machine: This type of plastic machine is characterized by pressure and temperature have been fixed, speed adjustable. The pressure between the rubber roller and the plastic sealing temperature have been set at the factory. The plastic sealing speed can be adjusted by the user or a two-speed adjustable speed laminating machine. The sealing fastness of the document is controlled by the plastic sealing speed. In fact, the adjustment speed is also to change the molding temperature. Fast speed, short heating time, low plastic sealing temperature, slow speed, long heating time and high plastic sealing temperature. The operation of such models should also be carried out one by one according to the procedures required by the process. If the speed is too fast, it will cause the document to be heated too low during the sealing process, and the opening speed will be too slow, and the heat will be supplied too much, which will cause the deformation of the document after sealing and overflow. The pressure of the speed-regulating laminator also has a certain adjustable range. If necessary, you can refer to the manual for proper fine-tuning.
3. Gear pump: This type of glue machine is generally called a glue machine. After heating the solid rubber powder or rubber block, it is in a liquid state. In the conveying pipe which is sucked into the heating by the gear pump, it drops and fog. It can be adhered to the material by means of chemical, scraping, coating, and slicing. The gear type pressure has a certain adjustable range. You can unload the cover by referring to the product description and make appropriate fine adjustment.
