Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] Please see Figure 1-3 In this embodiment of the present invention, a hot melt adhesive film winding device includes a roll 1, a hot melt adhesive film support cylinder 2, and an air pump 5. The roll 1 has a hollow structure, and multiple air inlets 10 are evenly spaced on its surface. An air pump mounting box 8 is fixed to one end of the roll 1, and an air pump mounting box cover 6 is installed on the side of the air pump mounting box 8. The air pump 5 is installed inside the air pump mounting box 8, and a motor connector 7 is fixed to the end of the air pump mounting box 8. The motor connector 7 is used to connect and fix to the output end of the motor. A power supply 9 for supplying power to the suction pump 5 is fixed on the box 8. The power supply 9 is equipped with a power switch 15. The hot melt adhesive film support cylinder 2 is sleeved on the roll 1. The hot melt adhesive film support cylinder 2 has a hollow structure. Multiple through holes 3 are evenly spaced on the surface of the hot melt adhesive film support cylinder 2. The diameter of the through holes 3 is larger than the diameter of the air inlet 10. The number of through holes 3 is less than the number of air inlet 10. A sealing plate 11 is fixed on the inner side of the end of the roll 1 away from the air pump mounting box 8. The sealing plate 11 can concentrate the air intake of the roll 1 on the air inlet 10.

[0018] A fixed side baffle 13 is fixed between the roll 1 and the air pump mounting box 8. A movable side baffle 4 is installed on the end of the roll 1 away from the air pump mounting box 8. Both the fixed side baffle 13 and the movable side baffle 4 are used to prevent the hot melt adhesive film from deviating during winding. The movable side baffle 4 is composed of a baffle body 17 and an insert 18. The insert 18 and the roll 1 are in clearance fit.

[0019] The end of the insert block 18 is embedded with a magnet 16, and a steel sheet 12 is embedded in the sealing plate 11. Through the attraction between the magnet 16 and the steel sheet 12, the movable side baffle 4 is more stable after being installed on the end of the drum 1.

[0020] The fixed side baffle 13 has multiple teeth 14 fixed at equal intervals on its side surface, and the movable side baffle 4 has multiple teeth 14 fixed at equal intervals on its side surface. The teeth 14 on the fixed side baffle 13 and the movable side baffle 4 are used to reinforce the hot melt adhesive film support cylinder 2 and prevent relative rotation between the hot melt adhesive film support cylinder 2 and the roll 1.

[0021] The working principle of this utility model is as follows: The roll 1 of this utility model has a hollow structure, and an air inlet 10 is provided on the surface of the roll 1. An air pump 5 is provided at the end of the roll 1. At the same time, a through hole 3 is also provided on the surface of the hot melt adhesive film support cylinder 2. When the starting end of the hot melt adhesive film is placed on the surface of the hot melt adhesive film support cylinder 2, the air pump 5 is operated, so that the external air enters the interior of the roll 1 through the through hole 3 and the air inlet 10, and then is discharged through the exhaust port of the air pump 5, thereby generating a negative pressure inside the roll 1, which in turn adsorbs and fixes the starting end of the hot melt adhesive film onto the hot melt adhesive film support cylinder 2. The continuous running time of the air pump 5 is set according to the number of layers of hot melt adhesive film wound by the hot melt adhesive film support cylinder 2. It is necessary to ensure that the hot melt adhesive film support cylinder 2 can still wound the hot melt adhesive film normally after the air pump 5 stops running.
