Description

Technical Field

[0001] The utility model relates to the technical field of elastic nonwoven fabric processing, in particular to a heating and stretching device used for preparing elastic nonwoven fabric. Background Art

[0002] Woven fabrics, also known as nonwoven fabrics and needle-punched cotton, are made of directional or random fibers. They are called cloth because they have the appearance and certain properties of cloth. Nonwoven fabrics are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, colorful, low-priced, and recyclable. During the processing and transmission of nonwoven fabrics, the tension on their surfaces may be uneven, resulting in wrinkles and creases, which will result in unsatisfactory results in the final product. Therefore, they need to be stretched and flattened during the transmission process.

[0003] For example, the utility model application number 202320694667.0 discloses a steam-heated stretching device for non-woven fabric production. The steam-heated stretching device for non-woven fabric production is provided with a stretching mechanism. The stretching mechanism of the device is provided between the second guide roller and the third guide roller. The stretching mechanism continuously applies an upward force to the sliding block through a spring, so that the non-woven fabric portion located between the second guide roller and the third guide roller is always in a taut state, so as to stretch it. In addition, rotating disks are provided on both sides of the stretching roller. The two rotating disks rotate synchronously, and the eccentrically arranged stretching rods on the surface thereof will periodically support the non-woven fabric, thereby further improving the stretching and leveling effect of the device, thereby improving the practicality of the device.

[0004] Similar to the above application, there are still some shortcomings:

[0005] This type of steam heating and stretching equipment for non-woven fabric production only achieves the effect of heating and stretching the non-woven fabric. In the process of using steam to heat the non-woven fabric, a large amount of water vapor will be generated and blown to the outside by the adsorbed fan. The water vapor is continuously discharged directly, causing great waste, reducing energy conservation and environmental protection. In addition, directly heating the non-woven fabric at high temperature may cause the fibers of the non-woven fabric to be damaged, affecting the quality of the non-woven fabric.

[0006] For this reason, a heating and stretching device for preparing elastic nonwoven fabrics is designed to optimize the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0027] like Figure 1-Figure 5 As shown, the present embodiment provides a heating and stretching device for preparing elastic non-woven fabrics, including a shell 1, a stretching mechanism 3 is arranged inside the shell 1, the stretching mechanism 3 includes a fixed block 23 and a support rod 24, the fixed block 23 is located on the inner side wall of the shell 1, and the support rod 24 is symmetrically fixed to the top of the fixed block 23, and the outer sides of the support rods 24 are sleeved with springs 25, and the tops of the springs 25 are fixed with sleeves 26, and the sleeves 26 are respectively sleeved on the tops of the support rods 24, and stretching rollers 27 are rotatably installed between the sleeves 26. The right end of the non-woven fabric is connected to the equipment of the next procedure, which has a certain traction force on the non-woven fabric. The setting of the spring 25 is used to push the non-woven fabric laid on the stretching roller 27 upward to achieve the purpose of stretching the non-woven fabric. Pressing rollers 2 are arranged inside the shell 1 and on both sides of the stretching mechanism 3. An air duct 4 is arranged through the top of the shell 1, and an air hood 6 is fixed at one end of the air duct 4 located inside the shell 1. A fan 5 is installed at the other end, an inclined plate 7 is symmetrically installed inside the induced draft hood 6, an L-shaped plate 8 is symmetrically installed at the bottom of the induced draft hood 6, a guide cover 10 is fixedly installed at the bottom of the L-shaped plate 8, and the guide cover 10 is a trumpet-shaped cover body, through the trumpet-shaped guide cover 10, hot steam is easier to gather and collect in the induced draft hood 6, and has a certain guide effect, the inside of the L-shaped plate 8 is all inclined and fixed with a guide block 9, one end of the guide block 9 is fixed with a water pipe 11, and a boiling water tank 14 is installed at the bottom end of the water pipe 11, and the driving wheels 12 are symmetrically installed inside the shell 1 and above the boiling water tank 14, and a conveying net 13 is arranged between the driving wheels 12, and a support block is fixed inside the shell 1 and below one end of the conveying net 13, and bristles are arranged on the support block, and the setting of the bristles is convenient for cleaning the rotating conveying net 13 and dredging the mesh of the conveying net 13, so that the high-temperature steam can be more easily blown through the mesh of the conveying net 13 to heat the non-woven fabric.

[0028] Specifically, the non-woven fabric passes through the driving wheel 12 and the conveying net 13 from left to right in turn, and the driving motor installed on the outside drives the driving wheel 12 to make the conveying net 13 rotate to the right. The boiling water tank 14 is heated inside to make the water vapor evaporate upward, and at the same time, the fan 5 is started to guide the high-temperature water vapor upward through the air duct 4 and the induced draft hood 6, so that part of the high-temperature water vapor passes through the non-woven fabric to heat the non-woven fabric, and part of the high-temperature steam enters the induced draft hood 6 and contacts the inclined plate 7. The moisture in the steam stays on the inclined plate 7 and slides onto the guide block 9 under the action of gravity through the inclined inclined plate 7, and then slides down and is collected in the water pipe 11 and returns to the boiling water tank 14 for recycling.

[0029] like Figure 1 As shown, a waste heat box 15 is fixed on one side of the casing 1 and below the fan 5, and the top of the waste heat box 15 is fixedly connected to the bottom of the fan 5, and an air supply hood 16 is fixed to the output end of the fan 5, and the bottom of the air supply hood 16 is arranged as an inclined surface. The air supply hood 16 with an inclined bottom makes it easier for the warm air on the right side to contact the non-woven fabric, so that the air is blown onto the non-woven fabric in a decreasing manner from left to right, and an insulation block is installed at the entrance of the waste heat box 15, and air holes 17 are evenly opened at the bottom of the air supply hood 16, and the size of the air holes 17 increases from left to right.

[0030] Specifically, the fan 5 draws the high-temperature steam into the interior of the air supply hood 16 through the air duct 4, and part of the heat is lost through the heated non-woven fabric and the high-temperature air flowing into the air duct 4, and then discharged from the air holes 17 at the bottom of the air supply hood 16 and blown to the surface of the non-woven fabric. The hot air from the air holes 17 on the left is more difficult to be blown onto the non-woven fabric than the hot air from the air holes 17 on the right, which has the effect of increasing the temperature.

[0031] like Figure 1 and Figure 4 As shown, a cleaning roller 18 is installed inside the waste heat box 15 and at a position obliquely below the air supply hood 16. Limit openings 19 are provided on both sides of the waste heat box 15. A movable rod 20 is movably installed inside the limit opening 19. The outer sides of the movable rod 20 are threadedly connected to a limit tube 22. A protective ring is provided on the outer side of the limit tube 22, and the protective ring is a thermal insulation protective ring. The setting of the thermal insulation protective ring reduces the risk factor during operation. A cleaning roller 21 is rotatably installed between the movable rods 20.

[0032] Specifically, the non-woven fabric enters the waste heat box 15 from the left side and is sandwiched between the cleaning roller 18 and the cleaning roller 21. The height of the cleaning roller 21 is adjusted up and down according to the thickness of the non-woven fabric. The cleaning roller 21 moves up and down while driving the outer movable rod 20 to move. When it reaches a suitable height, the limit tube 22 is tightened toward the outside of the waste heat box 15 to fix the cleaning roller 21. Then the non-woven fabric passes between the cleaning roller 21 and the cleaning roller 18 to stick to the dust and debris on the surface of the non-woven fabric, thereby reducing pollution to the inside of the outer shell 1.

[0033] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
