Description

Technical Field

[0001] This utility model relates to the field of BOPP film research and development technology, specifically to calendering equipment for film processing. Background Technology

[0002] BOPP film, or biaxially oriented polypropylene film, is an important flexible packaging material. It is mainly made by co-extruding polypropylene granules into sheets, which are then stretched in both longitudinal and transverse directions. In the BOPP film production process, after the polypropylene granules are extruded, calendering equipment is used to aid in film formation. The polypropylene granules, after being heated and softened, are calendered into film sheets under pressure through the gaps between two or more calendering rollers inside the equipment.

[0003] However, in actual operation of calendering equipment for thin film processing, the calendering components are generally directly exposed on the outside of the equipment. During long-term use, not only is it easy for a large amount of dust to accumulate on the outside, but it is also easy to be damaged by impact from external objects. This is a shortcoming and makes it inconvenient to protect the calendering equipment components from dust.

[0004] Now, a novel calendering equipment for thin film processing is proposed to address the above-mentioned shortcomings. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides an embodiment: a calendering equipment for thin film processing, including an equipment platform 1, a mounting platform 2 at the top of the equipment platform 1, a top cover 3 at the top of the mounting platform 2, a handle 4 fixed on the left side of the top cover 3, a viewing plate 8 fixed inside the top of the top of the top cover 3, fixing feet 13 fixed at both ends of the bottom right side of the top cover 3, fixing frames 14 fixed at both ends of the right side of the mounting platform 2, the fixing feet 13 and the fixing frames 14 are hinged to each other, openings 18 are opened inside the top cover 3 at both ends, and a controller 15 is fixedly installed on the right side of the front end of the equipment platform 1;

[0025] The viewing panel 8 is a transparent acrylic component, with openings 18 penetrating the interior of both ends of the top cover 3.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, a top cover 3 is installed on the outside of the calendering assembly on the top of the mounting platform 2. The top cover 3 can be used to provide an auxiliary outer cover for the outside of the calendering assembly, reducing dust accumulation on the outside of the calendering assembly, and also providing safety and impact protection for the outside.

[0027] The top cover 3 has a housing 9 installed and fixed on both sides of the top rear end. A fan 25 is installed and fixed on the top of the housing 9. A filter 26 is inserted and installed on the bottom of the housing 9. Air vents 27 are opened on both sides of the top rear end of the top cover 3. The air vents 27 penetrate the interior of the top of the top cover 3. The housing 9 is connected to the interior of the air vents 27.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, after the film material is calendered at the bottom of calendering roller 10 and calendering roller 22, the fans 25 inside the two sets of housings 9 at the top rear end of the top cover 3 can be started to draw in external air. After passing through the dust filters of the upper and lower sets of filters 26, the air is then blown out onto the surface of the film material through the air guide 27. This can help cool the calendered film and accelerate the film material forming.

[0029] A threaded sleeve 21 is movably connected at the middle position of the top of the equipment platform 1, and a disc tooth 24 is fixed to the outside of the threaded sleeve 21. A servo motor 22 is installed and fixed on the right side of the top of the equipment platform 1, and a bevel gear 23 is fixed to the output shaft of the servo motor 22. A lead screw 20 is threadedly connected inside the threaded sleeve 21. Guide rods 19 are fixed at the four corners of the bottom of the mounting platform 2. Sliding sleeves are fixed inside the four corners of the top of the equipment platform 1. The top of the lead screw 20 passes through the inside of the top of the equipment platform 1 and is fixedly connected to the bottom of the mounting platform 2. The bevel gear 23 is meshed with the disc tooth 24. The bottom of the guide rod 19 passes through the inside of the sliding sleeve.

[0030] Specifically, such as Figure 1 and Figure 3 As shown, the controllable servo motor 22 can start and drive the threaded sleeve 21 to rotate by meshing bevel gear 23 and disc gear 24. The rotation of the threaded sleeve 21 can drive the internally threaded lead screw 20 to move upward, and at the same time, the working height of the top calendering assembly can be adjusted up and down.

[0031] Mounting frame 1 7 is fixedly installed at the middle position of the top of mounting platform 2. A calendering roller 10 is laterally movably connected to the top of mounting frame 1 7, and a calendering roller 2 12 is laterally movably connected to the bottom of mounting frame 1 7. The right sides of calendering roller 1 10 and calendering roller 2 12 respectively penetrate the interior of the right side of mounting frame 1 7. Transmission gears 11 are fixedly fixed to the right sides of calendering roller 10 and calendering roller 2 12 respectively. A reducer 5 is fixedly installed at the bottom left side of mounting frame 1 7, and a drive motor 6 is fixedly installed at the front end of reducer 5. The two sets of transmission gears 11 are meshed together. The output shaft of drive motor 6 is fixedly connected to the input shaft of reducer 5. The output shaft of reducer 5 is fixedly connected to the left side of calendering roller 2 12. Mounting frame 2 16 is fixedly installed at both ends of the top of mounting platform 2, and an auxiliary roller 17 is laterally movably connected inside mounting frame 2 16.

[0032] Working Principle: In use, the processed film is fed into the auxiliary roller 17 at the front of the top of the equipment and then enters between calendering roller 10 and calendering roller 22 for calendering. After calendering, it can be discharged outward by the rear auxiliary roller 17. Simultaneously, when the calendering assembly is in use, a top cover 3 is installed on the outside of the calendering assembly at the top of the mounting platform 2. The top cover 3 provides auxiliary sealing to the outside of the calendering assembly, preventing dust accumulation and providing safety impact protection. Meanwhile, the film is pressed at the bottom of calendering roller 10 and calendering roller 22. Later, by controlling the start of the fans 25 inside the two sets of housings 9, external air is drawn in and filtered through the dust of the upper and lower sets of filters 26, and then blown out onto the surface of the film material through the air guide 27. This can assist in cooling the calendered film and accelerate the film forming. When the calendering equipment is installed and used, the servo motor 22 can also be started to drive the threaded sleeve 21 to rotate by the meshing bevel gear 23 and disc gear 24. The rotation of the threaded sleeve 21 can drive the internally threaded lead screw 20 to move upward, and at the same time, the height of the top calendering assembly can be adjusted.
