How to replace the heating strip of the vacuum packaging machine

The heating strip is a relatively important device on the food vacuum packaging machine , and the sealing is performed by the heating of the heating strip. The heating strip is one of the vulnerable parts of the vacuum packaging machine. After using it for a period of time, it needs to be adjusted and replaced due to the loss. Let's take a look at the adjustment and replacement of the heating strip of the food vacuum packaging machine. Content:

1. When replacing the heating strip of the food vacuum packaging machine, we need to loosen the fixing card of the single-chamber vacuum packaging machine, then remove the insulation cloth, untie the heating wire, then fix the screw and lift the heating rod. After that, the heating rod can be removed.

2. If the adhesive tape is damaged, it must be replaced. Two layers can be attached. Moreover, we also need to pay attention to the characteristics of the food vacuum packaging machine: it adopts a unique electric heating arrangement, and the feeding and discharging mode is the forward right-out type, and also considers the energy-saving design, which can effectively save energy, and the whole equipment body is compact. And the space occupied is also small; some key components are imported original zero-match, which improves the stability and reliability of the equipment.

3. Remove the broken heating piece, then remove the oxide layer of the heating wire fixing terminal, rotate the groove of one end of the new heating piece for one week, fix it on the insulating fixing block, and fix the other end to the other fixing block. Tighten the heater chip.

If the heating belt can not be used, you need to unscrew the nut at both ends, remove the copper screw, insert the replaced heating belt into the groove of the copper screw, and insert it into the heating rod to wrap the copper screw more than one turn, then adjust The heating belt is located in the middle of the width of the heating strip, screw the copper nut, and then the other end copper screw is loaded into the heating rod according to the above method (the heating rod can be reduced by more than the length if it is too long), and the copper screw is rotated to tighten the heating belt. , tighten the copper nut.

1, the first is the quality of the heating strip, you want the hot strip produced on the market will generally need to be replaced after about 1 week, this is because the quality of the heating strip is good, if the heating strip is nickel-plated, then It is not easy to burn, so it can be used more.

2, the heating strip is damaged because of the fixed ends of the heating strip, we now use a copper stud head for the heating strip produced in the market, so that after a period of use, it is easy to oxidize, which can cause heating Damage to the strip.

3. The last reason is the design problem of the control program. The correct heating procedure is to start the heating work after the heating belt is pressed to the sealing line, but many manufacturers blindly pursue the work efficiency and often do not have time to press the bag mouth to heat, resulting in the heating belt dry burning damage.
