Description

Technical Field

[0001] The utility model relates to the technical field of heat shrink machines, in particular to a tunnel oven type heat shrink machine. Background Art

[0002] The tunnel oven heat shrink machine is a device used to heat shrink products. Its main components include a tunnel oven and a transmission system, as well as components for heating and control. Its working principle is as follows: the product to be packaged is placed on the transmission system and enters the tunnel oven as the transmission system moves. In the oven, the product is evenly heated, and at the same time, the outer heat shrink film shrinks due to the heat and tightly wraps around the surface of the product. After preheating, constant temperature, cooling and cooling, the product is heat-shrunk and packaged and output from the other end of the oven.

[0003] Existing heat shrink machines, such as a POF heat shrink bag packaging machine disclosed in announcement number CN220663100U, although a transfer conveyor belt 1 and a conveyor belt 2 are arranged inside the tunnel-type heat shrink processing, the sealed POF heat shrink bags input from the material port are heat-shrunk and then output through the material port, which solves the problem that a worker is required at each end of the "tunnel" type conveying device to load and take out materials, thereby increasing the labor cost. However, after unifying the positions of the inlet and outlet ports, this heat shrink bag packaging machine is still inconvenient to automatically collect the heat-shrinked products in a unified manner during anti-sticking. For this reason, we propose a tunnel oven heat shrink machine. Utility Model Content
