Description

Technical Field

[0001] This utility model belongs to the field of impregnated fabric production technology, specifically relating to a heating and drying device for impregnated fabric production. Background Technology

[0002] Rubberized fabric is made by impregnating cotton or glass cloth with a solution of phenolic resin or by infusing it with molten phenolic resin. Impregnation is one of the most common processing methods in textile manufacturing. Impregnation involves passing the fabric through an impregnation tank, allowing the fabric fibers to absorb the resin and thus improving the bonding strength between the fabric and the resin. After production, the impregnated fabric requires drying, shearing, and winding.

[0003] For example, patent CN216898237U discloses a heating device for drying impregnated fabric production. The device drives the impregnated fabric body through a transmission roller, a first guide roller, and a second guide roller. The primary smoothing mechanism and the secondary smoothing mechanism work together to smooth the adhesive layer. The drying mechanism can quickly and evenly dry the upper and lower sides of the impregnated fabric. The impregnated fabric drying device of this utility model has a reasonable structural design and strong practicality. While drying both sides of the impregnated fabric evenly, it smooths the adhesive layer of the fabric to prevent the adhesive layer from cracking.

[0004] However, although the heating and drying device can dry the moisture in the dipped cloth, the adhesive layer in the heated dipped cloth will also soften, and then stick to the surface of the guide roller during the conveying process after drying, thus affecting the quality of the dipped cloth.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In this invention, after the heating wire is turned on and air is introduced into the air inlet pipe, the air entering the rectangular frame at the front of the drying chamber is heated by the heating wire and then enters the upper connecting pipe inside the drying chamber. It is then discharged from the air outlet pipe and blown onto the surface of the impregnated cloth entering the drying chamber, heating and drying the cloth. Simultaneously, compressed gas is introduced into the vortex tube to generate cold air, which enters the rectangular frame at the front of the cooling chamber. This cold air mixes with the air entering the cooling chamber and enters the upper connecting pipe inside the cooling chamber. It is then blown out through the air outlet pipe onto the dried impregnated cloth surface in the cooling chamber, cooling the softened adhesive and preventing it from easily sticking to the surfaces of the upper and lower transmission rollers, thus ensuring the quality of the impregnated cloth after winding.

[0019] In this invention, when the collection box is placed below the scraper hopper, the four corners of the collection box are positioned inside the limiting block, so that the collection box is accurately placed below the scraper hopper. As the adhesive-impregnated cloth passes through the scraper channel, the adhesive scraped off will flow along the inner wall of the scraper hopper into the collection box and be collected, thus avoiding waste of adhesive.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] This specific embodiment is a heating and drying device for the production of impregnated fabric, and its structural schematic diagram is shown below. Figure 1 and Figure 2 As shown, the system includes a base 1, a drying chamber 2 fixedly connected to the upper right end of the base 1, a cooling chamber 3 fixedly connected to the upper left end of the base 1, and a transmission mechanism provided at both ends of the upper side of the base 1. The transmission mechanism includes a rear support plate 401 fixedly connected to the left and right ends of the upper rear side of the base 1, a front support plate 402 fixedly connected to the left and right ends of the upper front side of the base 1, an upper rotating rod 403 rotatably connected to the upper end of the rear support plate 401 and the front support plate 402, and a lower rotating rod 404 rotatably connected to the upper support plate 401 and the front support plate 402 at a position below the upper rotating rod 403. A drive gear 405 is fixedly connected to the outer front end of the upper rotating rod 403, and a driven gear 406 is fixedly connected to the outer front end of the lower rotating rod 404. The upper rear end of the rear support plate 401... A motor 407 is installed. An upper transmission roller 408 is fixedly connected to the outer side of the upper rotating rod 403, and a lower transmission roller 409 is fixedly connected to the outer side of the lower rotating rod 404. A drive gear 405 and a driven gear 406 mesh. The front end of the output shaft of the motor 407 is fixedly connected to the rear end of the upper rotating rod 403. The outer side of the upper transmission roller 408 abuts against the upper side of the dipped cloth, and the outer side of the lower transmission roller 409 abuts against the lower side of the dipped cloth. Thus, when the output shaft of the motor 407 is started and rotates, it drives the upper rotating rod 403 to rotate. Through the transmission of the drive gear 405 and the driven gear 406, the lower rotating rod 404 can rotate relative to it, thereby causing the upper transmission roller 408 and the lower transmission roller 409 to rotate relative to each other, thus conveying the dipped cloth between the upper transmission roller 408 and the lower transmission roller 409.

[0029] Cooperate Figure 3 A scraping mechanism is installed on the upper side of the base 1, located to the right of the drying chamber 2. The scraping mechanism includes a support rod 501 fixedly connected to the upper side of the base 1 at both the front and rear ends to the right of the drying chamber 2. A scraping hopper 502 is fixedly connected to the upper end of the support rod 501. A collection box 503 is provided on the upper side of the base 1 below the scraping hopper 502. Limiting blocks 504 are fixedly connected to the four corners below the collection box 503 on the upper side of the base 1. A scraping channel begins at the middle position of the left end of the scraping hopper 502. The outer side of the dipped cloth is slidably connected to the inner side of the scraper channel, and the four corners of the outer side of the collection box 503 are slidably connected to the inner side of the limiting block 504. Thus, when the collection box 503 is placed below the scraper hopper 502, by making the four corners of the collection box 503 located inside the limiting block 504, the collection box 503 can be accurately placed below the scraper hopper 502. As the dipped cloth passes through the scraper channel, the glue scraped off will flow along the inner wall of the scraper hopper 502 into the collection box 503 and be collected, thus avoiding glue waste.

[0030] Cooperate Figure 4 and Figure 5 Drying chamber 2 and cooling chamber 3 are equipped with drying mechanisms at their inner and outer ends. Each drying mechanism includes an upper connecting pipe 601 fixedly connected to the upper and lower ends inside the drying chamber 2. An exhaust pipe 602 is fixedly connected at equal intervals to one adjacent end of the upper connecting pipe 601. A rectangular frame 603 is fixedly connected to the front end of the upper connecting pipe 601. An electric heating wire 604 is installed inside the rectangular frame 603 at the front of the drying chamber 2. An air inlet pipe 605 is fixedly connected to the front end of the rectangular frame 603. A vortex tube 606 is installed at the right end of the rectangular frame 603 at the front of the cooling chamber 3. Exhaust vents are located at the rear ends of both the drying chamber 2 and cooling chamber 3. Fabric penetration holes are provided at both the left and right ends of the drying chamber 2 and cooling chamber 3, through which the impregnated fabric passes. This allows air to be introduced into the air inlet pipe 605 after the electric heating wire 604 is turned on. Air entering the rectangular frame 603 at the front end of the drying chamber 2 is heated by the heating wire 604 and then enters the upper connecting pipe 601 inside the drying chamber 2. It is then discharged from the air outlet 602 and blown onto the surface of the dipped cloth entering the drying chamber 2 to heat and dry the dipped cloth. At the same time, compressed gas is introduced into the vortex tube 606 to generate cold air, which enters the rectangular frame 603 at the front end of the cooling chamber 3. It mixes with the air entering the interior to form cold air, which enters the upper connecting pipe 601 inside the cooling chamber 3. It is then blown out through the air outlet 602 onto the surface of the dried dipped cloth in the cooling chamber 3 to cool the glue that has softened due to the high temperature, so that it will no longer easily stick to the surface of the upper conveyor roller 408 and the lower conveyor roller 409, thus ensuring the quality of the dipped cloth after winding.

[0031] Working principle: When drying the impregnated cloth, the cloth is conveyed by the relatively rotating upper conveyor roller 408 and lower conveyor roller 409. As it passes through the drying chamber 2 and cooling chamber 3, the heating wire 604 is turned on to circulate air into the air inlet pipe 605. The air entering the rectangular frame 603 at the front end of the drying chamber 2 is heated by the heating wire 604 and then enters the upper connecting pipe 601 inside the drying chamber 2. It is then discharged from the air outlet pipe 602 and blown onto the surface of the impregnated cloth in the drying chamber 2 to heat and dry it. At the same time, compressed gas is introduced into the vortex pipe 606 to generate cold air, which enters the rectangular frame 603 at the front end of the cooling chamber 3. It mixes with the air entering the frame and forms cold air, which enters the upper connecting pipe 601 inside the cooling chamber 3. It is then blown out through the air outlet pipe 602 onto the surface of the dried impregnated cloth in the cooling chamber 3 to cool the softened adhesive due to the high temperature. Finally, it is discharged from the left end and collected for subsequent processing.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
