[0007] Furthermore, a material roller is movably provided on one side of the machine body.

[0008] Furthermore, four rollers are fixedly arranged on the bottom of the body, and the four rollers are respectively located at four corners of the bottom of the body.

[0009] Furthermore, both front and rear ends of the upper roller are movably connected to the slider via a rotating shaft, and the slider is slidably connected to the slide groove.

[0010] Furthermore, the bottom of the adjusting screw rod passes through the connecting plate and the slider in sequence and is movably connected to the bottom of the slide groove through a rotating shaft, and the adjusting screw rod is threadedly connected to the slider.

[0011] Furthermore, guide grooves are provided on both sides of the slider, and the guide grooves and the slider are integrated into one.

[0012] Furthermore, guide rods are provided at middle positions on both sides of the sliding block, and opposite sides of the two guide rods extend into the interior of the guide groove and are slidably connected to the guide groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The laminating machine for the packaging box with adjustable tension is capable of adjusting the tension when the device is in use by arranging an adjusting screw rod, a slider, a guide rod and a guide groove, so that the user can reasonably control the tension according to needs, avoid the film material from being too loose or too tight, improve the production efficiency of the product, bring convenience to the user, improve the practicality of the device, and meet the user's usage needs.
