Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
The principle of the scheme is as follows: after a thermal shrinkage film sleeve mark is formed by a film sleeving machine, the film is put into a primary thermal oven for primary thermal shrinkage (120 ℃, 3-5 minutes) to reach 90% of the planned final shrinkage rate; and then, taking off the preformed shrink film on the mold by a hand or a mechanical arm, sleeving the preformed shrink film on a product package, and then, entering a secondary heat oven for final heat shrinkage (the oven temperature is 120 ℃ for 10 seconds), so that the temperature rise of the product can be ensured not to exceed 1 ℃. Simultaneously, an infrared temperature probe is respectively arranged at an inlet and an outlet of the second hot oven, so that the temperature change of the product before and after the product is discharged is monitored in real time, and the product quality can be well controlled.
With reference to figures 1 and 2 of the drawings,
a product film covering device is used for protecting a film covering device for liquid or powder product packages which are sensitive to temperature. Comprises the following steps:
