Description

Technical Field

[0001] This utility model belongs to the field of non-woven fabric drying, specifically relating to a non-woven fabric processing drying oven. Background Technology

[0002] A horizontal nonwoven fabric drying oven is a drying device with horizontally conveyed nonwoven fabric as its core. It is widely used in the production of nonwoven fabrics for drying rolls or continuous rolls. It heats the air through a heating system, and the hot air circulates in the oven under the action of a fan, making full contact with the nonwoven fabric, removing the moisture from the nonwoven fabric or melting the low-melting-point fibers in the nonwoven fabric, so as to achieve the purpose of drying or curing and shaping.

[0003] In existing technologies, traditional horizontal nonwoven fabric drying ovens often suffer from fiber shedding and adhesion during the drying process because impurities are not removed from the surface of the nonwoven fabric before drying. This affects the quality of the nonwoven fabric, especially for medical and filter applications where high cleanliness is required; inferior quality nonwoven fabrics are unsuitable. Furthermore, the traditional nonwoven fabric conveying structure uses a simple guide roller structure, which easily leads to fabric misalignment, wrinkles, or uneven tension during actual use, resulting in uneven drying. Therefore, this invention proposes a nonwoven fabric processing drying oven to solve the problems existing in the prior art. Utility Model Content

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5 This utility model provides an embodiment: a non-woven fabric processing drying oven, including a lower drying box 2, and an automatic fabric loading and unloading structure with cleaning function installed on the lower drying box 2. An upper drying box 4 is installed at the upper end of the lower drying box 2. A fourth roller frame 9 is fixedly connected to the inner walls of both the front and rear ends of the lower drying box 2. A third roller frame 8 is fixedly connected to the center of the inner wall of the lower drying box 2. A tension roller 11 is rotatably installed on the fourth roller frame 9. The automatic fabric loading and unloading structure includes a first roller frame 1 and a second roller frame 3 installed on the front and rear sides of the lower drying box 2, two sets of cleaning brush rollers 13 rotatably installed on the third roller frame 8 and arranged symmetrically on top and bottom, and two sets of dust suction heads 19 installed on the front and rear sides of the cleaning brush rollers 13. A storage roller 14 is rotatably installed on the first roller frame 1, and a receiving roller 15 is rotatably installed on the second roller frame 3. Two sets of bearing mesh plates 12 are symmetrically distributed on the inner wall of the lower drying box 2.

[0022] By pre-treating the brush roller 13 and cleaning it in real time with negative pressure suction, the cleanliness of the product is guaranteed in two ways. In addition, the staggered notch guidance of the feed plate 20 and the discharge plate 22, the tension control of the tension roller 11, and the support of the carrying mesh plate 12 ensure a smooth transmission process and avoid morphological defects.

[0023] Please see Figures 3-4In this embodiment, the inner walls of the front and rear ends of the upper drying box 4 are equipped with a discharge plate 22 and a feed plate 20. The lower end of the discharge plate 22 has a notch, and the upper end of the feed plate 20 has a notch. One end of the nonwoven fabric body 6 is rolled onto the storage roller 14, and the other end of the nonwoven fabric body 6 passes through the feed plate 20, two sets of tension rollers 11, two sets of cleaning brush rollers 13 and the discharge plate 22 and is rolled onto the take-up roller 15. The notch design of the feed plate 20 and the discharge plate 22 forms a staggered guide, which can accurately guide the nonwoven fabric into and out of the drying box, avoid deviation or wrinkles during the transmission process, and reduce the direct leakage of high-temperature gas in the box through the inlet and outlet, reduce heat loss, and improve heat utilization. In conjunction with the tension rollers 11, the tension of the nonwoven fabric can be kept stable during the drying process to ensure uniform heating. The cleaning brush rollers 13 can remove floating dust and fiber debris from the surface of the nonwoven fabric before drying, and improve the cleanliness of the final product.

[0024] Please see Figures 3-5 In this embodiment, a motor frame 16 is fixedly connected to the right end of the second roller frame 3. A drive motor 17 is installed on the motor frame 16. The output end of the drive motor 17 passes through the second roller frame 3 and is connected to the receiving roller 15. The motor frame 16 is independently fixed to the second roller frame 3 to reduce the impact of motor vibration on the roller frame and other components, reduce equipment noise, and extend the service life of the transmission system. A negative pressure vacuum cleaner 5 is installed at the upper center of the upper drying box 4. The negative pressure vacuum cleaner 5 passes through two sets of through holes 18 in the center of the upper drying box 4 via a corrugated pipe and is connected to two sets of suction heads 19. The negative pressure vacuum cleaner can remove short fibers, dust, and volatiles that fall off the surface of the non-woven fabric during the drying process in real time, preventing impurities from adhering to the surface of the non-woven fabric and affecting the quality. At the same time, it reduces dust accumulation in the box and reduces the frequency of equipment cleaning. The third roller frame 8 is located between the two sets of the second roller frame 3. Between the four roller frames 9, two sets of supporting mesh plates 12 are distributed between the two sets of fourth roller frames 9 and one set of third roller frames 8. The design of the supporting mesh plates 12 does not block the flow of hot air, ensuring that heat can penetrate the upper and lower surfaces of the nonwoven fabric, thereby improving drying efficiency. At the same time, the grouped layout makes it easy to adjust the support range according to the width of the nonwoven fabric, adapting to different specifications of products. The bottom of the lower drying box 2 is equipped with a lower electric heating dryer 7, and the inner walls at both ends of the lower drying box 2 are equipped with baffles 10. The lower inner wall of the upper drying box 4 is equipped with two sets of upper electric heating dryers 21 that are symmetrically distributed front and back. The symmetrical electric heating dryers form double-sided heating, which can heat the front and back sides of the nonwoven fabric at the same time, shortening the drying time and improving efficiency. Moreover, the heating area is symmetrically distributed front and back, ensuring that the nonwoven fabric is heated evenly during the transmission process, reducing the quality difference caused by local temperature differences.

[0025] Please see Figure 5In this embodiment, the air outlets of the lower electric heating dryer 7 and the upper electric heating dryer 21 correspond to each other. The bottom of the lower drying box 2, the first roller frame 1 and the second roller frame 3 are provided with feet. The corresponding air outlets can form convective hot air, allowing the hot airflow to directly penetrate the nonwoven fabric, enhancing the heat exchange efficiency, and avoiding local heat accumulation in the box. It is especially suitable for deep drying of thick nonwoven fabrics.

[0026] When in use, first load the non-woven fabric body 6 rolls onto the storage roller 14 of the first roller frame 1, and manually guide its free end through the upper notch of the feed plate 20 at the front end of the upper drying box 4 into the interior of the upper drying box 4 and the lower drying box 2.

[0027] After the nonwoven fabric enters the upper drying box 4 and the lower drying box 2, it passes in sequence through the tension roller 11 on the fourth roller frame 9 to maintain stable tension and the two sets of cleaning brush rollers 13 on the third roller frame 8. The cleaning brush rollers 13 can remove floating dust, short fibers and other impurities from the surface of the nonwoven fabric body 6 during the conveying and drying process, thus completing the pretreatment.

[0028] Next, the pre-treated nonwoven fabric is supported by the support mesh plate 12 and enters the core drying area. The lower electric heating dryer 7 at the bottom of the lower drying box 2 and the upper electric heating dryer 21 at the bottom of the upper drying box 4 work simultaneously. The air outlets form convective hot air, which penetrates the front and back of the nonwoven fabric for heating and drying. The baffle 10 of the lower drying box 2 reduces heat loss and improves thermal efficiency.

[0029] During the drying process, the negative pressure vacuum cleaner 5 at the top of the upper drying box 4 uses two sets of vacuum heads 19 to suck away the loose fibers, volatiles and dust in real time to avoid secondary pollution.

[0030] Finally, the dried nonwoven fabric passes through the lower notch of the discharge plate 22 at the rear end of the upper drying box 4 and is guided by the take-up roller 15 on the second roller frame 3. The take-up roller 15 is driven by the drive motor 17 on the motor frame 16 to ensure stable transmission speed.

[0031] By integrating the pretreatment and impurity removal using the cleaning brush roller 13, the core heating using convection drying, and the real-time cleaning using negative pressure dust extraction into the same process, no additional procedures are required, the production cycle is shortened, and the overall product quality is improved. It is especially suitable for high-cleanliness scenarios and solves the problem that existing horizontal nonwoven fabric drying ovens are difficult to pretreat the surface of nonwoven fabrics during use.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
