Heat Shrink Machine It is suitable for tight packaging of multiple items and pallet packaging

Heat shrink machines, also known as shrink machines or heat shrink packaging machines, are one of the more advanced packaging methods in the current market. Wrap the product or packaging with shrink film, and after heating, make the shrink film tightly wrap the product or packaging, fully displaying the appearance of the item, enhancing the marketability of the product, and increasing the aesthetic appeal and sense of value. At the same time, the packaged items can be sealed, moisture-proof, pollution-proof, and protect the goods from external impacts, providing a certain degree of cushioning. Especially when packaging fragile items, it can prevent the vessels from scattering when they break. In addition, it can reduce the possibility of the product being disassembled or stolen. It is suitable for tight packaging of multiple items and pallet packaging. Heat shrink machines are widely used in the packaging of items such as glass bottles, foam plastics, paper boxes, toys, electronics, electrical appliances, stationery, books, records, hardware tools, daily necessities, medicines, cosmetics, beverages, fruits, and commemorative labels. Another type is a tableware shrink machine, which is specifically designed for the heat shrinkage of tableware. This tableware shrink machine equipment is particularly suitable for large-scale heat shrink film forming and packaging in industries such as catering tableware, software, printed materials, biscuits, pharmaceuticals, ceramics, beverages, and flooring. It belongs to a type of packaging machine.

Mechanical structure and working principle
1. It adopts quartz far-infrared tubes for heating. During operation, it can continuously generate infrared radiation. Combined with a powerful wind circulation, the temperature in the heating chamber becomes more uniform, while also saving electricity.
2. The conveying part adopts high-power DC motors, which are characterized by stepless speed regulation and a relatively high load capacity. It can work continuously for a long time and operates stably and reliably.
3. It adopts a special mechanical structure design, making the appearance more beautiful and luxurious, and also making maintenance easy and convenient.
4. All electrical components are made of high-quality and well-known brands, effectively ensuring the quality of the entire machine.
5. Any type of shrink film can be perfectly shrink packaged.

Power supply equipment and precautions
Like the wrapping machine, the heat shrink machine consumes a lot of power. Therefore, the power of the input power supply must be greater than the rated power on the nameplate of the shrink machine; otherwise, it is easy to burn out the circuit or electrical components.
2. Just like the strapping machine, the machine must be reliably grounded to protect personal safety.
Each machine is equipped with a power connection cable when leaving the factory. The lead part at the end of the cable is marked with the power identification symbol. It must be connected correctly. Violation of operating procedures may cause electric shock.
4. When the specified voltage of the machine is three-phase 380V power supply, the neutral wire must be input simultaneously, that is, the standard three-phase four-wire system. The same applies to other packaging equipment, such as vacuum packaging machines. Otherwise, the machine cannot work properly and is very likely to burn out the internal electrical components.
5. The machine must be installed horizontally; otherwise, the service life of the electric heating tube will be shortened. For machines with mesh belt transmission, their inclined installation will cause the conveyor belt to deviate from the center.
When the machine has been in continuous use for more than three months, the temperature-resistant wires in the shrinkage chamber should be inspected and replaced as appropriate based on their degree of aging.
When the ⒎ machine is in operation, the operator's palm and other parts are not allowed to come into contact with the moving parts of the machine, especially the temperature inside the contraction chamber is extremely high, which can easily cause burns.
After the packaging work is completed, the heating switch should be turned off first. Let the conveying motor and the fan motor continue to run for about 10 minutes, and then cut off the entire power supply.

The main operating procedures of the heat shrink machine:
a) Close the power switch and the power will be connected. Start the conveyor belt and preheat it for about 5 minutes. Then close the fan switch. At this point, adjust the temperature control knobs of the upper and lower chambers and the conveying speed according to the size of the items and the thickness of the film. After debugging and meeting the usage requirements, shrink packaging can be carried out.
b) In actual situations, if there are too many wrinkles after shrinkage, the conveying speed can be reduced or the heating temperature can be increased but not exceeding the seventh gear. Conversely, if over-shrinkage occurs, the temperature can be lowered or the conveying speed can be increased but not exceeding the seventh gear. (Under the condition of 220V voltage)
c) After the operation is completed, first turn off the heating switch, let the conveying motor and the hot air motor continue to run for about 10 minutes, and then cut off the entire power supply.
