Description

Technical Field

[0001] The utility model relates to the technical field of PET materials, in particular to a production device for low-warpage and high-strength PET materials. Background Art

[0002] Polyethylene terephthalate (PET) is a crystalline polymer with relatively high melting temperature and glass transition temperature. It maintains excellent physical and mechanical properties within a certain temperature range. Its fatigue resistance, friction resistance, aging resistance, and electrical insulation properties are extremely prominent, and it has the characteristics of low warpage and high strength. Therefore, it is widely used in fields such as synthetic fibers, films, and engineering plastics.

[0003] A cooling device for PET sheet materials in the prior art (publication number: CN220808462U) is disclosed, which includes two mounting plates. Two cooling rollers corresponding up and down are arranged in the middle of the two mounting plates. A sponge for adsorbing water droplets on the surface of the cooling roller is arranged on the front side of each cooling roller, and a set of mounting components for mounting adjacent sponges is arranged corresponding to each cooling roller in the middle of the two mounting plates.

[0004] However, the above technical solution and the prior art also have the following defects:

[0005] During the use of this utility model, the sponge arranged on the front side of the cooling roller is used to adsorb the water droplets generated on the surface of the cooling roller. However, when the sponge absorbs too much water and becomes saturated, it loses the adsorption effect on the water droplets on the surface of the cooling roller. It is necessary to regularly disassemble the sponge from the mounting component to remove the water in it, or replace it with a new sponge, resulting in the need to stop the continuously operating production equipment to replace the sponge, increasing the work difficulty and affecting the work efficiency.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0026] Embodiment 1:

[0027] A low-warpage and high-strength PET material production device includes a frame 1 and a cooling roller 2. There are two cooling rollers 2 arranged up and down on the frame 1. The extruded PET material is guided through the middle of the two cooling rollers 2, and the two cooling rollers 2 are used to cool and solidify the PET material. One side of the cooling roller 2 is provided with a water-absorbing roller 3 for adsorbing the water droplets on the surface of the cooling roller 2. The water-absorbing roller 3 is installed in a water-absorbing and drying mechanism 4. The water-absorbing and drying mechanism 4 is used for the water absorption and drying of the water-absorbing roller 3 to ensure the water absorption effect of the water-absorbing roller 3, thereby ensuring the adsorption of the water droplets on the surface of the cooling roller 2 and effectively avoiding the water absorption saturation of the water-absorbing roller 3;

[0028] A cooling and drying mechanism 7 is arranged at the rear of the cooling roller 2. The cooling and drying mechanism 7 is used for blowing and cooling the PET material to further cool and solidify the PET material and enhance the drying effect on the surface of the PET material.

[0029] The water-absorbing and drying mechanism 4 includes a mounting box 401, a mounting cavity 402, a first branch pipe 403, a first fan 404, a first main pipe 405, a collection box 406 and a first connecting pipe 407. The interior of the mounting box 401 is provided with a mounting cavity 402, which is adapted to the water-absorbing cotton 302. The upper part of the mounting box 401 is connected to the first main pipe 405 through the first branch pipe 403. The first main pipe 405 is connected to the air inlet end of the first fan 404. The air outlet end of the first fan 404 is connected to the collection box 406 through the first connecting pipe 407. The collection box 406 is used for filtering and collecting water.

[0030] Mounting grooves 5 are provided at the midpoints of both ends of the mounting cavity 402. The mounting grooves 5 are adapted to the positioning shafts 303. The positioning shafts 303 are fixedly installed in the mounting grooves 5 through nuts. The water-absorbing roller 3 includes a fixed cylinder 301, water-absorbing cotton 302 and positioning shafts 303. The water-absorbing cotton 302 is fixedly installed on the outer surface of the fixed cylinder 301 and abuts against the surface of the cooling roller 2. The positioning shafts 303 are provided at both ends of the fixed cylinder 301. By providing the mounting grooves 5 and the positioning shafts 303, the installation of the water-absorbing roller 3 is realized and it is convenient to disassemble and replace it.

[0031] At both ends of the installation box 401, first installation side plates 6 are fixedly installed, and the first installation side plates 6 are fixedly installed on the frame 1 by screws.

[0032] In this embodiment, by arranging the water absorption roller 3 in the water absorption and drying mechanism 4, the water absorption and drying mechanism 4 is used to suck out the water adsorbed on the water absorption roller 3, effectively avoiding the adsorption saturation of the water absorption roller 3, which affects the water absorption effect on the surface of the cooling roller 2. There is no need to disassemble, replace, and clean the water on the water absorption roller 3, improving work efficiency. Since the water absorption roller 3 is adaptively installed in the installation cavity 402 of the installation box 401, one side of the water absorption cotton 302 on the water absorption roller 3 is located outside the installation cavity 402 and abuts against the surface of the cooling roller 2. Driven by the high-strength first blower 404, the blower with strong suction sucks the water adsorbed in the water absorption cotton 302 in the installation cavity 402 into the collection box 406, avoiding the saturation of the water absorption cotton 302, thereby ensuring the adsorption of the water on the surface of the cooling roller 2 by the water absorption cotton 302 and ensuring the cooling effect of the cooling roller 2.

[0033] Embodiment Two:

[0034] Based on Embodiment One, the cooling and drying mechanism 7 mentioned in Embodiment One is described:

[0035] The cooling and drying mechanism 7 includes an air box 701, a second branch pipe 702, a second main pipe 703, a second blower 704, a second connecting pipe 705, and an air distribution plate 706. The air boxes 701 are symmetrically arranged on the frame 1, and the air boxes 701 are arranged at the rear side of the cooling roller 2. The upper part of the air box 701 is connected to the second main pipe 703 through the second branch pipe 702. The second main pipe 703 is connected to the air outlet end of the second blower 704. The air inlet end of the second blower 704 is connected to the air cooling device through the second connecting pipe 705. The bottom of the air box 701 is installed with the air distribution plate 706 by screws. The air distribution plate 706 evenly blows the cold air onto the surface of the PET material, ensuring an even cooling effect.

[0036] Second installation side plates 8 are fixedly installed on both sides of the air box 701, and the second installation side plates 8 are fixedly installed on the frame 1 by screws.

[0037] In this embodiment, by arranging the cooling and drying mechanism 7 at the rear side of the cooling roller 2, further cooling and drying of the PET material cooled by the cooling roller 2 are achieved, ensuring the production effect. Driven by the second blower 704, the cooling air generated by the air cooling device is transported into the air box 701. The cooling air is evenly blown onto the upper and lower surfaces of the PET material through the air distribution plate 706 at the bottom of the air box 701, achieving further cooling and drying of the cooled material and ensuring the production effect.

[0038] Working principle: By guiding the extruded PET material through the middle of two cooling rollers 2, the two cooling rollers 2 are used to cool and solidify the PET material. If water droplets appear on the surface of the cooling roller 2 during the cooling process, since the cooling roller 2 is in a rolling state during operation, the outer surface of the rotating cooling roller 2 abuts against the absorbent cotton 302 on the outer side of the fixed water-absorbing roller 3, and the absorbent cotton 302 is used to adsorb the water droplets on the surface of the cooling roller 2. After the absorbent cotton 302 absorbs water, the water diffuses in the absorbent cotton 302. Since the water-absorbing roller 3 is installed in the installation cavity 402 of the installation box 401, the inner side wall of the installation cavity 402 abuts against the absorbent cotton 302, and the driving of the first fan 404 is used to suck the water in the absorbent cotton 302 in the installation cavity 402 into the collection box 406 to ensure the water absorption effect of the absorbent cotton 302, so as to continuously adsorb the water droplets generated on the surface of the cooling roller 2 and ensure the progress of the work. The PET material cooled by the cooling roller 2 passes between the upper and lower air boxes 701, and the cooling and drying mechanism 7 blows and cools and dries the material passing between the air boxes 701 to ensure the production effect of the material.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
