Can sealing machine failure analysis Daquan

Can sealing machine It is mainly used to encapsulate the items to be packaged. After decades of development, it has become one of the packaging machinery products with complete types and satisfactory functions. Can sealing machines can be divided into can sealing machines without sealing materials, can sealing machines with sealing materials, and can sealing machines with auxiliary sealing materials. According to the mechanical properties of packaging materials, there are two types: rigid container sealing machine and flexible container sealing device. Commonly used rigid container sealing machines include screw cap sealing machine, piping sealing machine, rolling pattern sealing machine, plug sealing machine, gland sealing machine, crimping sealing machine, etc. Different can sealing machines can realize the sealing of different types of goods. As the types of can sealing machines increase, their applications in the industry have become more and more extensive. During the use of the can seaming machine, we often encounter such failures. Let's take a look at the common failures during the use of the can seaming machine.
(1) The sealing of the can is not strong, and the cause of the failure is that the pressure of the cold-pressed rubber wheel is not suitable, the heat sealing speed is too fast, the heat sealing temperature is not enough, and the quality of the heat sealing film is defective. In this case, the heat sealing temperature can be appropriately increased. , Then reduce the heat sealing speed and increase the pressure of the cold-pressed rubber wheel.
(2) The thermometer display is out of order, the sealing temperature is out of control, the heat sealing temperature is not constant, the sealing place is either burnt, or the sealing is not strong, the sealing is deformed, and it is ugly. The main reason for the failure is that the thermometer is broken. It must be repaired; in addition, the thermocouple may also be broken, and the induced temperature cannot be transmitted to the thermometer normally. Just replace the thermocouple with the same model and specification.
(3) The can seamer goes and stops, and the speed is inconsistent. The main cause of the failure is that the shaft connection of the motor and the gearbox connection are falling off and loose. Re-tighten the screws to make them all coincide. solved.
(4) Irregular marks and bubbles appear at the sealing area. Such failures are more common, mainly due to irregularly arranged uneven marks on the cold-pressed rubber wheel, which are directly reflected on the packaging, causing more occurrences at the sealing area. Obvious marks, the equipment has been used for a long time, and dust and plastic scraps are attached to the high-temperature belt, which causes the high-temperature belt to be uneven and uneven, which makes the sealing of the can unevenly heated, and bubbles appear after being pressed by the cold pressing wheel. Replace the cold-pressed rubber wheel, clean or replace the high-temperature belt again to eliminate the fault.
