Packaging machinery using long time, especially in continuous operation under overload conditions , prone to some electrical faults and mechanical failures, such as : sealing strong, machine stop and go, the fuse blows, running issued a " squeak start " can not control the temperature , the seal deformation and bending finished bags , bubbles or irregular patterns and other sealing knife marks imprint place. Combining practical experience , for which several faults , analyze its causes, put forward the corresponding solutions, and elaborated continuous sealing machine maintenance problems , we want to use continuous sealing machine business and personal help. 1 sealing sealing unsound unsound is a common fault continuous sealing machine , sealing is not strong has three meanings : ① the seal can not be sealed bags ; ② sealing knife under pressure, although the sealed bag , but squeeze a little harder or tear strip , sealing blamed cracking ; when ③ on the seal peel test , half seal appears solid, half isolated phenomenon, this bag sealing quality is still unsatisfactory , because the contents of the storage process it is easy to miss in extruded . In this case, the composite lining for the OPP, often occurs when a blow PE. The first major cause of failure following reasons . (1) Under normal circumstances sealing temperature is not enough to OPP as lining bag, when the bag when the total thickness of 80 ~ 90μm, sealing temperature to reach 170 ~ 180 ℃; in PE bags for the composite lining system when the total thickness of the bag 85 ~ 100μm, the temperature should be controlled at 180 ~ 200 ℃. As long as the increase in the total thickness of the bag , sealing temperature must be increased accordingly. ( 2 ) sealing too fast closure and sealing machine is not catchy but also the speed of the speed related. If the speed is too fast, the seal has not yet had time to pull the roller heating was transferred to the cold of the cooling treatment , naturally reach the sealing quality requirements. ( 3 ) Cold tire pressure tire inappropriate cold down each one , the pressure between them should be moderate, when adjusting the pressure to just clamp spring . ( 4 ) sealing sealing sealing film quality is not a problem with the quality of the film is also concerned with the sealing , if the composite lining corona treatment is uneven, ineffective, and just appeared in the seal , and certainly can not be sealed. This situation is rare, however, in the event , product must be scrapped. So color printing and packaging industry , is under the supervision procedure on the procedure, one found quality problems , we must analyze the causes and resolve them promptly . If the seal moisture , dirt , can also cause sealing strong. In short , to solve the problem of the first seal is not strong , and can be an appropriate increase in heat sealing temperature , and then reduce the heat-seal packaging machine FAQ Q :
Sometimes the film packaging deviation , which is why ?
A: The film generated mostly because deviation phenomenon related components caused by improper position adjustment can proceed from the following three aspects make the appropriate adjustments:
Adjust the center forming the film to make it consistent with the mounting shaft center
If the first is no problem , it may be misaligned teeth hot rollers , hot rollers need to be adjusted
May stick with the vertical roller polyester , needed a brush except to ask:
After packing bags can not be completely cut , causing several bags together
A: The copper hammer gently tap the fixed blade , adjust the distance between the fixed blade and rotary cutter until the cut normal to ask:
Sealing temperature display abnormal heat sealing temperature instability
A: It may be a thermocouple or damage caused by poor contact , need to re- install or replace thermocouple thermocouple, if the thermocouple is normal, that is, solid state relays or temperature controller is damaged and must be replaced to ask :
Seal a sealing uneven , or a few packets in a packet of hot uneven pressure
A: This phenomenon is due to the heat roll surface wear caused by the need to remove the surface dirt heat roller ( particularly polyethylene residues ) , head to be careful not to damage the surface of heat-resistant resin sheet , especially when operating , can not with a hard object to scratch . Q:
Longitudinal sealing and transverse sealing the junction wrinkled , horizontal sealing of the wrinkles, resulting in inadequate sealing beautiful
A: The cause of this phenomenon is probably not in the center position under the nozzle or the lower nozzle is too long, it may be skewed rods hold the bag to ask:
When the machine is running , do not turn the cross seal
A: The cause of the failure of many possibilities , most likely longitudinal seal failure caused encoder should focus on to find the cause from the longitudinal sealing encoder:
Longitudinal sealing encoder wiring plug is loose or poor contact
Longitudinal sealing loose coupling shaft encoder
Longitudinal sealing completely damaged encoder asked :
After the machine is powered tripping phenomenon
A: The cause of this phenomenon may be heating rods or other electrical components insulation bad need of replacement parts is poor insulation asked :
Machine operation, the transverse seal appeared and bag length are not allowed to play Dayton
A: The cause of this phenomenon may be the greatest longitudinal sealing encoder has been damaged to ask:
Machine running at low speed , and press the " Stop" button non-stop
A : You can proceed to find the cause of the following three aspects :
Origin proximity switch produces loose or damaged resulting in no signal
Wang Feng encoder damage
Horizontal shaft seal loose encoder connection
