Description

Technical Field

[0001] This utility model relates to the technical field of plastic film production, and in particular to a cooling device for plastic film production. Background Technology

[0002] A plastic film cooling device is a device used to cool films, playing a crucial role in the film production process. When using the blown film method to produce film, the raw material is extruded and blown to form the film, which is then cooled and shaped by the cooling device before being wound up. In the prior art, utility model patent application number 202221508188.7 discloses a rapid cooling device for plastic films in the packaging bag production process. It mainly consists of a cold air blower and a spray assembly. In use, the film to be cooled is blown with cold air by the cold air blower, and water is sprayed onto the film through the spray assembly to cool it down. After cooling, the film is wound up. However, this device has the following problem: it can only cool the film and cannot cut the film to the appropriate width according to customer needs, resulting in high limitations and inconvenience. Therefore, a film production cooling device with a cutting function is needed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a plastic film production cooling device that can not only cool and shape plastic films, but also cut plastic films to a suitable width. It is easy to use, has low limitations, and is highly practical.

[0004] This utility model discloses a cooling device for plastic film production, comprising a base plate and a winding machine, with the winding machine mounted on the upper end of the base plate. It also includes three support plates, three guide rollers, a cooling mechanism, and a cutting mechanism. The three support plates are all mounted on the base plate, and the three guide rollers are rotatably mounted on the three support plates respectively. The cooling mechanism is mounted on the base plate and is used to cool the film. The cutting mechanism is also mounted on the base plate and has the function of cutting the film. During plastic film production, when cooling the plastic film, it passes through the cooling mechanism to achieve a lower temperature. The three guide rollers guide the movement of the plastic film. The cutting mechanism then cuts the cooled plastic film to a suitable width, and the winding machine then rewinds the cut plastic film. This device not only cools and shapes the plastic film but also cuts it to a suitable width, making it convenient to use, with low limitations and high practicality.

[0005] Preferably, the cooling mechanism includes a support frame, a cooler, and a blower pipe. The support frame is fixedly mounted on the base plate, the cooler is fixedly mounted on the upper end of the support frame, and the output end of the cooler is provided with a blower pipe, which is fixedly mounted on the support frame. Multiple exhaust ports are provided at the lower part of the blower pipe. When cooling the plastic film, as the plastic film passes under the blower pipe, the cooler is turned on, and the cooler blows cold air onto the plastic film through the blower pipe, thus cooling and shaping the plastic film. This facilitates the cooling of the plastic film.

[0006] Preferably, it also includes a fixed plate and a water-cooling roller. The fixed plate is fixedly installed on the base plate, and the water-cooling roller is rotatably installed on the fixed plate. The water-cooling roller is connected to an external cooling water circulation mechanism. When cooling the plastic film, after the plastic film is cooled by the air blower, it is guided by one of the guide rollers and then passes through the water-cooling roller. When the plastic film passes through the water-cooling roller, it exchanges heat with the cooling water inside the water-cooling roller through the side wall of the water-cooling roller, thereby cooling the plastic film and improving the cooling effect.

[0007] Preferably, the cutting mechanism includes a vertical plate, a servo motor, a lead screw, two sets of sliders, a slide rail, and two sets of cutting shears. The vertical plate is fixedly installed on the upper end of the base plate, the servo motor is fixedly installed on the vertical plate, and the lead screw is rotatably installed on the vertical plate. The front and rear parts of the lead screw are respectively provided with external threads in opposite directions. The two sets of sliders are respectively screwed to the front and rear parts of the lead screw. Both sets of sliders are slidably installed on the slide rail, which is fixedly installed on the upper end of the base plate. The two sets of cutting shears are respectively fixedly installed on the upper ends of the two sets of sliders. When the servo motor is turned on, the servo motor drives the lead screw to rotate. The rotation drives the two sets of sliders to adjust the distance, thereby adjusting the distance between the two sets of cutting shears so that the distance between the two sets of cutting shears is adapted to the required film width. When the cooled plastic film passes through the two sets of cutting shears, the plastic film is cut to the appropriate width by the two sets of cutting shears, which facilitates the cutting of plastic film.

[0008] Preferably, the assembly also includes a moving mechanism, a fixed frame, a dust-adhesive roller, and a drive motor. The fixed frame is mounted on the moving mechanism, which is used to move the fixed frame. The dust-adhesive roller is rotatably mounted on the fixed frame. The drive motor is fixedly mounted on the fixed frame, and its output end has a rotating shaft, which is rotatably mounted on the fixed frame and fixedly connected to the dust-adhesive roller. When the plastic film is not cooled, and when it is necessary to clean the dust from the surface of the water-cooling roller and the guide roller, the moving mechanism moves the fixed frame, causing the dust-adhesive roller to contact the water-cooling roller or the guide roller. Then, the drive motor is turned on, causing the dust-adhesive roller to rotate. During the rotation, the dust-adhesive roller also rotates the water-cooling roller or the guide roller, thus cleaning the dust and impurities from the surface of the water-cooling roller and the guide roller. This facilitates the cleaning of the surface of the water-cooling roller and the guide roller.

[0009] Preferably, the moving mechanism includes a hoisting frame, an electric slide rail, a sliding block, a hydraulic cylinder, and a lifting rod. The hoisting frame is fixedly installed at the lower end of the electric slide rail, the sliding block is installed on the electric slide rail, and the electric slide rail is used to move the sliding block left and right. The hydraulic cylinder is fixedly installed at the lower end of the sliding block, and the lifting rod is installed at the output end of the hydraulic cylinder, and the lifting rod is used to raise and lower the hydraulic cylinder. The fixed frame is fixedly installed at the lower end of the lifting rod, and the dust-adhesive roller is located above the water-cooling roller and the guide roller. The hoisting frame is fixedly hoisted on the support frame of the workshop. When moving the fixed frame left and right, the electric slide rail is opened, and the electric slide rail moves the hydraulic cylinder, the lifting rod, and the fixed frame in the left and right directions through the sliding block. When adjusting the height of the fixed frame, the hydraulic cylinder is opened, and the hydraulic cylinder adjusts the height of the fixed frame through the lifting rod. Since the height of the fixed frame is adjustable, and the position of the fixed frame in the left and right directions is adjustable, the fixed frame can drive the dust-adhesive roller to move in the left and right directions and in the up and down directions, so that the dust-adhesive roller can be moved as needed to contact the water-cooling roller or the guide roller to clean the dust on the surface of the water-cooling roller or the guide roller.

[0010] Preferably, the surface of the guide roller is provided with a rubber layer; this arrangement reduces scratches on the plastic film by the guide roller and improves reliability.

[0011] Compared with the prior art, the advantages of this utility model are: it can not only cool and shape plastic film, but also cut plastic film to a suitable width, which is convenient to use, has low limitations, and is highly practical. Attached Figure Description

[0020] like Figures 1 to 5 The plastic film production cooling device of this utility model includes a base plate 1, a winding machine 2, three support plates 3, three guide rollers 4, a cooling mechanism, and a cutting mechanism. The winding machine 2 is installed on the upper end of the base plate 1, the three support plates 3 are all installed on the base plate 1, and the three guide rollers 4 are rotatably installed on the three support plates 3 respectively. The cooling mechanism is installed on the base plate 1 and is used to cool the film. The cutting mechanism is installed on the base plate 1 and has the function of cutting the film. When producing plastic film 25, when cooling plastic film 25, plastic film 25 is cooled by passing through the cooling mechanism and guided by the three guide rollers 4. Then, the cutting mechanism cuts the cooled plastic film 25 to a suitable width. Finally, the winding machine 2 winds up the cut plastic film 25. It can not only cool and shape plastic film 25, but also cut plastic film 25 to a suitable width. It is convenient to use, has low limitations, and is highly practical.

[0021] like Figure 1 and Figure 3 The cooling mechanism includes a support frame 5, a cooler 6, and a blower pipe 7. The support frame 5 is fixedly installed on the base plate 1, and the cooler 6 is fixedly installed on the upper end of the support frame 5. The output end of the cooler 6 is provided with a blower pipe 7, which is fixedly installed on the support frame 5. Multiple exhaust ports are provided at the lower part of the blower pipe 7. When cooling the plastic film 25, when the plastic film 25 passes under the blower pipe 7, the cooler 6 is turned on, and the cooler 6 blows cold air onto the plastic film 25 through the blower pipe 7 to cool and set the plastic film 25. This facilitates the cooling of the plastic film 25.

[0022] like Figure 1 and Figure 2 It also includes a fixed plate 8 and a water-cooling roller 9. The fixed plate 8 is fixedly installed on the base plate 1, and the water-cooling roller 9 is rotatably installed on the fixed plate 8. The water-cooling roller 9 is connected to an external cooling water circulation mechanism. When cooling the plastic film 25, after the plastic film 25 is cooled by the air blower 7, the plastic film 25 is guided by one of the guide rollers 4 and then passes through the water-cooling roller 9. When the plastic film 25 passes through the water-cooling roller 9, the plastic film 25 exchanges heat with the cooling water inside the water-cooling roller 9 through the side wall of the water-cooling roller 9, thereby cooling the plastic film 25 and improving the cooling effect of the plastic film 25.

[0023] like Figure 1 and Figure 5 The cutting mechanism includes a vertical plate 10, a servo motor 11, a lead screw 12, two sets of sliders 13, a slide rail 14, and two sets of cutting shears 15.

The two sets of sliders 13 are respectively screwed to the front and rear parts of the lead screw 12. Both sets of sliders 13 are slidably installed on the slide rail 14. The slide rail 14 is fixedly installed on the base plate 1. At the end, two sets of cutting shears 15 are fixedly installed on the upper ends of two sets of sliders 13 respectively; when the servo motor 11 is turned on, the servo motor 11 drives the lead screw 12 to rotate, and the rotation drives the two sets of sliders 13 to adjust the distance, thereby adjusting the distance between the two sets of cutting shears 15 so that the distance between the two sets of cutting shears 15 is adapted to the required film width. When the cooled plastic film 25 passes through the two sets of cutting shears 15, it is cut to the appropriate width by the two sets of cutting shears 15; thus facilitating the cutting of the plastic film 25.

[0024] like Figure 1 , Figure 2 and Figure 4It also includes a moving mechanism, a fixed frame 17, a dust-adhesive roller 18, and a drive motor 19. The fixed frame 17 is mounted on the moving mechanism, which is used to move the fixed frame 17. The dust-adhesive roller 18 is rotatably mounted on the fixed frame 17. The drive motor 19 is fixedly mounted on the fixed frame 17. The output end of the drive motor 19 is provided with a rotating shaft, which is rotatably mounted on the fixed frame 17 and fixedly connected to the dust-adhesive roller 18. When the plastic film 25 is not cooled, and when it is necessary to clean the dust on the surface of the water-cooling roller 9 and the guide roller 4, the fixed frame 17 is moved by the moving mechanism, so that the dust-adhesive roller 18 comes into contact with the water-cooling roller 9 or the guide roller 4. Then, the drive motor 19 is turned on, and the drive motor 19 drives the dust-adhesive roller 18 to rotate. During the rotation, the dust-adhesive roller 18 drives the water-cooling roller 9 or the guide roller 4 to rotate. The dust and impurities on the surface of the water-cooling roller 9 and the guide roller 4 can be cleaned by the dust-adhesive roller 18. This facilitates the cleaning of the surface of the water-cooling roller 9 and the guide roller 4.

[0025] like Figure 1 The moving mechanism includes a hoisting frame 20, an electric slide rail 21, a sliding block 22, a hydraulic cylinder 23, and a lifting rod 24. The hoisting frame 20 is fixedly installed at the lower end of the electric slide rail 21. The sliding block 22 is installed on the electric slide rail 21, and the electric slide rail 21 is used to move the sliding block 22 left and right. The hydraulic cylinder 23 is fixedly installed at the lower end of the sliding block 22. The lifting rod 24 is installed at the output end of the hydraulic cylinder 23, and the lifting rod 24 is used to raise and lower the hydraulic cylinder 23. The fixed frame 17 is fixedly installed at the lower end of the lifting rod 24. The dust-adhesive roller 18 is located above the water-cooling roller 9 and the guide roller 4. The hoisting frame 20 is fixedly hoisted on the workshop's support frame. When the fixed frame 17 is moved left and right... Open the electric slide rail 21. The electric slide rail 21 moves the hydraulic cylinder 23, lifting rod 24 and fixed frame 17 in the left and right directions through the sliding block 22. When adjusting the height of the fixed frame 17, open the hydraulic cylinder 23. The hydraulic cylinder 23 adjusts the height of the fixed frame 17 through the lifting rod 24. Since the height of the fixed frame 17 can be adjusted and its position in the left and right directions can be adjusted, the fixed frame 17 can drive the dust sticking roller 18 to move in the left and right directions and up and down directions. Therefore, the dust sticking roller 18 can be moved as needed to contact the water cooling roller 9 or the guide roller 4 to clean the dust on the surface of the water cooling roller 9 or the guide roller 4.
