[0001] The utility model belongs to the field of non-woven fabric production equipment, in particular to hot air non-woven fabric production circulation drying equipment. Background Art

[0002] Hot air non-woven fabric is a special type of non-woven fabric. It uses hot air to penetrate the fiber web and melt it to bond it. This production method makes hot air non-woven fabric fluffy, soft, elastic, and warm, but its strength is low and it is easy to deform. In order to enhance its strength, a certain proportion of low-melting point adhesive fiber or bi-component fiber, or functional oils and reagents are usually mixed into the fiber web.

[0003] During the production process of hot air non-woven fabrics, which are deeply processed by spraying special functional oils, flavor enhancers or antibacterial agents, the residual moisture inside the non-woven fabrics can easily cause the non-woven fabrics to mold during storage. The existing drying equipment usually uses a conveyor belt to dry the non-woven fabrics, and this method can only dry the non-woven fabrics on one side, resulting in poor drying effect on the non-woven fabrics. It also takes up more space, making the use of the drying equipment more inconvenient.

[0004] To this end, the utility model provides a hot air non-woven fabric production circulation drying equipment. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Specific examples are given below.

[0026] like Figures 1 to 4As shown, a hot air non-woven fabric production circulation drying equipment described in an embodiment of the utility model comprises a supporting base 1; a drying tank body 2 is provided on the top of the supporting base 1; an opening and closing door 3 is installed inside the drying tank body 2; a plurality of supporting columns 4 are fixedly connected to the bottom of the drying tank body 2, and the supporting columns 4 are regularly arranged in a circular array at the bottom of the drying tank body 2; the bottom of the supporting columns 4 is fixedly connected to the top position of the supporting base 1; a plurality of groups of first rotating frames 5 are fixedly connected to the inner side wall of the drying tank body 2, and each group of first rotating frames 5 has two symmetrically arranged; a plurality of groups of the first rotating frames 5 are arranged in a threaded array inside the drying tank body 2; a material guide wheel 6 is rotatably connected between each group of the first rotating frames 5; a circulation pipe 7 is connected between the top of the drying tank body 2 and the bottom of the drying tank body 2; a circulation pump is installed on the circulation pipe 7, and a heating device; a feed port and a discharge port are provided on the side wall of the support base 1, and the feed port is arranged at a position corresponding to the bottom of the support base 1, and the discharge port is arranged at a position corresponding to the top of the support base 1; during operation, when it is necessary to dry the non-woven fabric, the non-woven fabric can be passed through the feed port, passed through each guide wheel 6, and then led out through the discharge port, and then the non-woven fabric can be rolled up by the winding device. During the rolling process, the air inside the drying tank body 2 can be circulated by cooperating with the circulation pump and the circulation pipe 7. During the air circulation process, the air can be heated by arranging a heater inside the support base 1. By arranging a guide wheel 6 inside the drying tank body 2 to support the non-woven fabric, the non-woven fabric can be dried on both sides, so that the drying effect of the non-woven fabric is better. At the same time, the spirally arranged guide wheel 6 can make the device occupy a smaller area, making the device more convenient to use.

[0027] like Figure 6 to Figure 7 As shown, a filter screen 8 is fixedly connected to the inside of the circulation pipe 7; the shape and size of the filter screen 8 are arranged corresponding to the inner wall of the circulation pipe 7; when working, when the circulation pipe 7 circulates and heats the air inside the drying tank body 2, the air may move together with the lint and impurities on the surface of the non-woven fabric, thereby causing pollution to the subsequent non-woven fabric. By arranging the filter screen 8 inside the circulation pipe 7, the lint and impurities can be blocked, thereby effectively preventing the lint and impurities from polluting the subsequent non-woven fabric.

[0028] like Figure 6 to Figure 7As shown, a second rotating frame 9 is fixedly connected to the inside of the circulation pipe 7; a rotating shaft 10 is rotatably connected to the inside of the second rotating frame 9; a plurality of driving blades 11 are fixedly connected to the end of the rotating shaft 10, and the driving blades 11 are regularly arranged in a circular array on the side wall of the rotating shaft 10; a plurality of scraper plates 12 are fixedly connected to the other end of the rotating shaft 10, and the scraper plates 12 are regularly arranged in a circular array on the side wall of the rotating shaft 10; the side wall of the scraper plate 12 is in contact with the side wall of the filter screen 8; during operation, when the air is circulated through the circulation pipe 7, the air will push the driving blades 11, thereby driving the rotating shaft 10 and the scraper plates 12 to rotate together, so that the scraper plates 12 can scrape and clean the impurities adhering to the surface of the filter screen 8, effectively avoiding the situation where the impurities may cause clogging of the filter screen 8.

[0029] like Figure 2 , Figure 6 and Figure 7 As shown, a support frame 13 is fixedly connected to the bottom of the circulation pipe 7; a collecting bucket 14 is slidably fitted inside the support frame 13; the collecting bucket 14 is arranged at a position corresponding to the bottom of the filter screen 8; when working, after the scraper plate 12 scrapes and cleans the impurities on the surface of the filter screen 8, the impurities can be cleaned by arranging the support frame 13 and the collecting bucket 14 at the bottom of the circulation pipe 7, thereby making it more convenient to collect the impurities.

[0030] like Figure 5 As shown, a positioning block 15 is fixedly connected to the end of the rotating shaft of the guide wheel 6; the positioning block 15 is rotatably connected to the internal position of the first rotating frame 5; during operation, when the guide wheel 6 rotates inside the first rotating frame 5, the rotation of the positioning block 15 is restricted in the first rotating frame 5, so that the guide wheel 6 is less likely to tilt during the rotation process, and the rotation of the guide wheel 6 is more stable.

[0031] like Figure 5 As shown, a plurality of anti-wear balls 16 are provided between the first rotating frame 5 and the positioning block 15; the side walls of the anti-wear balls 16 are in contact with the side walls of the first rotating frame 5 and the positioning block 15; during operation, when the positioning block 15 rotates inside the first rotating frame 5, by providing the anti-wear balls 16 between the first rotating frame 5 and the positioning block 15, the sliding friction between the first rotating frame 5 and the positioning block 15 can be converted into rolling friction, so that the friction force between the first rotating frame 5 and the positioning block 15 is less, thereby reducing the wear between the first rotating frame 5 and the positioning block 15.

[0032] During operation, when the non-woven fabric needs to be dried, the non-woven fabric can be passed through the feed port, through each guide wheel 6, and then led out through the discharge port. Thereafter, the non-woven fabric can be rolled up by the winding device. During the rolling process, the air inside the drying tank body 2 can be circulated by cooperating with the circulation pump and the circulation pipe 7. During the air circulation process, the air can be heated by arranging a heater inside the support base 1. By arranging a guide wheel 6 inside the drying tank body 2 to support the non-woven fabric, the non-woven fabric can be dried on both sides, so that the drying effect of the non-woven fabric is better. At the same time, the spirally arranged guide wheel 6 can make the device occupy a smaller area, making the device more convenient to use.

[0033] When the circulation pipe 7 circulates and heats the air inside the drying tank body 2, the air may move the lint and impurities on the surface of the non-woven fabric together, causing pollution to the subsequent non-woven fabric. By arranging a filter net 8 inside the circulation pipe 7, the lint and impurities can be blocked, thereby effectively preventing the lint and impurities from polluting the subsequent non-woven fabric.

[0034] When the air is circulated through the circulation pipe 7, the air will push the driving blade 11, thereby driving the rotating shaft 10 and the scraper plate 12 to rotate together, so that the impurities adhering to the surface of the filter screen 8 can be scraped and cleaned by the scraper plate 12, effectively avoiding the situation where the impurities may cause blockage to the filter screen 8.

[0035] After the scraper plate 12 scrapes and cleans the impurities on the surface of the filter screen 8, the impurities can be cleaned by arranging a support frame 13 and a collection bucket 14 at the bottom of the circulation pipe 7, thereby making it more convenient to collect the impurities.

[0036] When the guide wheel 6 rotates inside the first rotating frame 5, by limiting the rotation of the positioning block 15 in the first rotating frame 5, the guide wheel 6 is less likely to tilt during the rotation, making the rotation of the guide wheel 6 more stable.

[0037] When the positioning block 15 rotates inside the first rotating frame 5, by arranging the anti-wear balls 16 between the first rotating frame 5 and the positioning block 15, the sliding friction between the first rotating frame 5 and the positioning block 15 can be changed into rolling friction, so that the friction force between the first rotating frame 5 and the positioning block 15 is less, thereby reducing the wear between the first rotating frame 5 and the positioning block 15.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
