DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in the present embodiment, a uniform cooling device for PE film production comprises a cooling box 1, a feeding port 9 is provided on one side of the cooling box 1, a discharging port 12 is provided on the side of the cooling box 1 away from the feeding port 9, a fixed plate 2 is fixedly connected to the outside of the cooling box 1 and located on one side of the feeding port 9 and the discharging port 12, a guide assembly is provided on one side of the fixed plate 2, a transverse plate 8 is fixedly connected to the inside of the cooling box 1, through holes 13 are equidistantly provided on the surface of the transverse plate 8, a displacement plate 7 is slidably connected to the inside of the cooling box 1 and located at the bottom of the transverse plate 8, an air outlet plate 14 is fixedly connected to the top of the displacement plate 7, a fan 15 is fixedly installed equidistantly between the displacement plate 7 and the air outlet plate 14, an adjusting assembly is provided to the inside of the cooling box 1 and located on the outside of the displacement plate 7, an observation window 11 is provided on one side of the cooling box 1, and a cover plate 24 is rotatably connected to the top of the cooling box 1.

[0022] First, the PE film is placed through the feed port 9 and passed through the guide assembly, and then the cover plate 24 is opened to wrap the PE film with the guide assembly, and then the guide assembly is pulled out from the outside of the discharge port 12, and then the cover plate 24 is closed, and the fan 15 is started to operate, and the blown wind passes through the air outlet plate 14 and the through hole 13 to reach the inside of the cooling box 1, thereby cooling the PE film, and then the guide assembly can make the PE film move more smoothly during cooling, and the PE film can be fully and evenly cooled inside the cooling box 1, thereby increasing the cooling effect of the device, and then when it is necessary to adjust the air volume, the adjustment assembly is started to drive the displacement plate 7 to move and the air outlet plate 14 to move, so that the holes inside the air outlet plate 14 are staggered with the through hole 13, thereby reducing the air volume, so that the air volume of the device can be conveniently adjusted, avoiding the problem that the traditional cooling device cannot be flexibly adjusted according to actual needs, and this fixed air volume control method may cause the problem that the best cooling effect cannot be achieved under different production conditions, thereby increasing the practicality of the device.

[0023] like Figure 1-Figure 4As shown, the adjustment component includes a reciprocating screw 10, which is rotatably connected to the inside of the cooling box 1. A motor 3 is fixedly installed on one side of the cooling box 1, and one end of the output shaft of the motor 3 is fixedly connected to one end of the reciprocating screw 10. A threaded groove is provided inside the displacement plate 7 and is threadedly connected to the outer side of the reciprocating screw 10. The adjustment component also includes a vertical plate 18, which is fixedly connected to the inside of the cooling box 1 and is located on one side of the displacement plate 7. A limiting groove 16 is provided on the surface of the vertical plate 18, and a limiting rod 17 is slidably connected to the inside of the limiting groove 16, and one side of the limiting rod 17 is fixedly connected to one side of the displacement plate 7.

[0024] When adjusting the air volume of the device, the reciprocating screw 10 is driven to rotate by starting the output shaft of the motor 3, and at the same time the displacement plate 7 is driven to move, thereby driving the limit rod 17 to slide inside the limit groove 16, so as to limit and guide the movement of the displacement plate 7. Then the movement of the displacement plate 7 drives the air outlet plate 14 to move, so that the hole of the air outlet plate 14 is staggered with the through hole 13 inside the horizontal plate 8. In this way, the air volume flowing from the fan 15 to the through hole 13 can be reduced, thereby achieving the effect of controlling the air volume.

[0025] like Figure 1-Figure 4 As shown, the guide assembly includes a slide rod 21, which is slidably connected to the inside of the fixed plate 2, and the bottom of the slide rod 21 is fixedly connected to a mounting plate 22. The guide assembly also includes a limit block 20, which is fixedly connected to the top of the slide rod 21, and a spring 19 is fixedly connected between the bottom of the limit block 20 and the top of the fixed plate 2, and a guide roller 23 is rotatably connected to the inside of the mounting plate 22. The inside of the cooling box 1 is fixedly connected to a first fixed rod 4, the inside of the cooling box 1 is fixedly connected to a second fixed rod 5 at the bottom of the first fixed rod 4, and the inside of the cooling box 1 is fixedly connected to a third fixed rod 6 at one side of the discharge port 12.

[0026] When the PE film moves, the outer side of the PE film contacts the guide roller 23, thereby driving the mounting plate 22 to move and driving the slide bar 21 to slide inside the fixed plate 2. Then the spring 19 is stretched, and then under the reaction force of the spring 19, the guide roller 23 is always in contact with the outer side of the PE film, thereby guiding the movement of the PE film to make it move more smoothly. Then the PE film passes through the first fixed rod 4, the second fixed rod 5 and the third fixed rod 6 in turn, thereby increasing the residence time of the PE film inside the cooling box 1, thereby increasing the cooling effect. Then the PE film moves out from the guide roller 23 on the side of the discharge port 12 to complete the cooling of the PE film.

[0027] The utility model provides a uniform cooling device for PE film production, and the specific working principle is as follows: first, the outer side of the PE film contacts the guide roller 23, thereby driving the mounting plate 22 to move and driving the slide bar 21 to slide inside the fixed plate 2, then the spring 19 is stretched, and then the guide roller 23 is always in contact with the outer side of the PE film under the reaction force of the spring 19, thereby guiding the movement of the PE film to make it move more smoothly, and then the PE film passes through the first fixed rod 4, the second fixed rod 5 and the third fixed rod 6 in sequence, so that the residence time of the PE film in the cooling box 1 is increased, thereby making The cooling effect is increased, and then when the air output of the device is adjusted, the reciprocating screw 10 is driven to rotate by starting the output shaft of the motor 3, and the displacement plate 7 is driven to move, thereby driving the limiting rod 17 to slide inside the limiting groove 16, so that the movement of the displacement plate 7 is limited and guided, and then the movement of the displacement plate 7 drives the air outlet plate 14 to move, so that the holes of the air outlet plate 14 are staggered with the through holes 13 inside the cross plate 8, so that the air volume flowing from the fan 15 to the through holes 13 can be reduced, thereby achieving the effect of controlling the air output, and finally the PE film is moved out from the guide roller 23 on the side of the discharge port 12 to complete the cooling of the PE film.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
