Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and more specifically, to a fabric dryer. Background Technology

[0002] Dryers can be divided into industrial and civilian types. In the fabric production process, the fabric needs to be dried after washing. Drying methods include hot air flow and radiation. Dryers are also divided into belt dryers, drum dryers and box dryers.

[0003] A textile fabric drying device with application number CN202021998294.9 has the following technical solution: it includes a heating mechanism, a lifting mechanism, and a resistance mechanism mounted on a lifting plate. The lifting plate is fixedly connected to the lifting end of the lifting mechanism. The resistance mechanism includes a sliding rheostat pointer, a sliding rheostat resistor, and a power supply. The sliding rheostat pointer is fixedly connected to the lifting plate and electrically connected to the heating mechanism. The sliding rheostat pointer overlaps with the sliding rheostat resistor, and the bottom end of the sliding rheostat resistor is electrically connected to the power supply. The power supply is electrically connected to the heating mechanism. A fabric conveyor belt is located directly below the heating mechanism.

[0004] The above technical solution allows for simultaneous adjustment of heating distance and temperature during the drying of textile fabrics. This simultaneous adjustment of both aspects improves drying intensity, adjustment range, and speed. Belt dryers dry fabrics using hot airflow. Fabrics to be dried are stacked in storage baskets and sequentially conveyed into the dryer. However, the dryer's heating channels are relatively long. When continuously drying fabrics of varying thicknesses, the above technical solution requires manual adjustment by workers based on fabric thickness. If workers fail to adjust the temperature promptly or accurately, or if any electrical equipment malfunctions, the drying temperature cannot be accurately controlled. In this case, thicker fabrics may not dry completely, while thinner fabrics may suffer heat damage. Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fabric dryer.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fabric dryer, comprising a machine body and a conveyor belt disposed inside the machine body, wherein a plurality of heating tubes extending into the machine body are disposed on the top and bottom surfaces of the machine body, and a plurality of cover plates covering the plurality of heating tubes are slidably connected to the top and bottom surfaces of the machine body, wherein the number of cover plates is half the total number of heating tubes, and the plurality of cover plates are all located on the side of the machine body away from the feed inlet of the conveyor belt, wherein a drive wheel for driving the cover plates to slide is rotatably connected inside the machine body, and the drive wheel abuts against the fabric and rotates in a direction away from the feed inlet of the conveyor belt.

[0007] The present invention is further configured such that: the drive wheel is located at the central axis of the machine body along its length, and a support rod for rotating the drive wheel is fixedly connected to the inner wall of the machine body, the support rod being located at the end of the drive wheel away from the fabric.

[0008] The present invention is further configured such that: a pull rope is sleeved on the outer peripheral wall of the drive wheel, the other end of the pull rope is fixedly connected to the outer peripheral wall of the cover plate, and adjacent cover plates arranged along the length direction of the machine body are fixedly connected by a pull rod.

[0009] The present invention is further configured such that: the end of the pull rope away from the cover plate passes around the side wall of the drive wheel away from the cover plate and is then fixedly connected to the bottom surface of the drive wheel.

[0010] The present invention is further configured such that: a slide rail is provided on the inner top surface and the inner bottom surface of the body respectively; a plurality of slide rods are fixedly connected to the top surface of the cover plate and slidably connected in the slide rail; and the plurality of slide rods on the same cover plate form a ventilation cavity communicating with the interior of the body.

[0011] The present invention is further configured such that: a plurality of elastic elements are fixedly connected to the inner wall of the machine body on the side away from the feed inlet of the conveyor belt, and the other end of the elastic elements is fixedly connected to the outer peripheral wall of the slide rod.

[0012] The present invention is further configured such that the surfaces of the drive wheel, cover plate, and slide rod are all coated with a high-temperature resistant coating.

[0013] In summary, the present invention has the following beneficial effects: In the initial state, there is a space between the bottom surface of the drive wheel and the conveyor belt for thinner fabric to pass through, and at this time, several cover plates cover all the heating tubes. If the fabric entering the machine is thick, the fabric will push the drive wheel to rotate, and the drive wheel will drive the cover plates to rotate, so that the heat in the heating tubes can directly contact the fabric, thus ensuring the heating effect of the fabric.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] A fabric dryer, such as Figure 1 and Figure 2 As shown, the machine includes a body 1 and a conveyor belt 2 installed inside the body 1. A storage basket is placed at the inlet of the conveyor belt 2. Fabrics to be dried are placed in the storage basket and pass through the conveyor belt 2 in sequence for drying. Several heating tubes 3 are installed on the top and bottom surfaces of the body 1, extending into the body 1. Therefore, the heating tubes 3 can heat both sides of the fabric simultaneously, ensuring heating efficiency. Several cover plates 4 covering the heating tubes 3 are slidably connected to the top and bottom surfaces of the body 1. The cover plates 4 reduce the high-temperature gas in direct contact with the fabric, preventing thin and easy-to-dry fabrics from being damaged by prolonged contact with high-temperature gas. The total number of cover plates 4 is half the total number of heating tubes 3, and all cover plates 4 are located on the half of the body 1 away from the storage basket. Therefore, sufficient heat can be ensured to contact the fabric, and some easy-to-dry fabrics will not accumulate more heat on their surface when passing through the half of the body 1 away from the storage basket, ensuring the drying quality of the fabric.

[0020] like Figures 1-3 As shown, slide rails 9 are provided on the inner top and bottom surfaces of the body 1. Several slide rods 10 are integrally formed on the top surface of the cover plate 4 and are slidably connected to the slide rails 9. The length of the slide rods 10 is greater than the distance between the inner top surface of the body 1 and the upper surface of the cover plate 4. Therefore, a heat passage is formed between the bottom surface of the heating tube 3 and the top surface of the cover plate 4. Several slide rods 10 on the same cover plate 4 form a ventilation cavity that communicates with the inside of the body 1. Therefore, the heat will not come into direct contact with the fabric, but the heat inside the body 1 is kept stable. At the same time, it can avoid the situation where a large amount of heat accumulates in the ventilation cavity and reduces the service life of the cover plate 4.

[0021] like Figures 1-3As shown, a drive wheel 5, which drives the cover plate 4 to slide, is rotatably connected at the central axis of the machine body 1 along its length. A support rod 6, which supports the rotation of the drive wheel 5, is welded to the inner wall of the machine body 1. The support rod 6 is located at the end of the drive wheel 5 away from the fabric. By changing the rotation point of the drive wheel 5, the distance that the end of the drive wheel 5 closest to the fabric can move is increased. In the initial state, there is a distance between the drive wheel 5 and the top surface of the conveyor belt 2 for the fabric to pass through. If a thinner fabric passes under the drive wheel 5, the fabric will not exert a pushing force on the drive wheel 5. Therefore, all the cover plates 4 can cover the heating tubes 3, preventing the heat in the heating tubes 3 from directly contacting the fabric. If a thicker fabric passes through, the fabric will exert a pushing force on the drive wheel 5, causing the drive wheel 5 to rotate away from the storage basket. At this time, the drive wheel 5 will drive the cover plate 4 to slide away from under the heating tubes 3, allowing the heat in the heating tubes 3 to directly contact the fabric, ensuring the overall heating efficiency of the dryer.

[0022] like Figures 1-3 As shown, a pull rope 7 is fitted onto the outer peripheral wall of the drive wheel 5. One end of the pull rope 7 is attached to the side wall of the cover plate 4 closest to the drive wheel 5, and the other end of the pull rope 7 is attached to the bottom surface of the drive wheel 5 after passing around the side wall away from the cover plate 4. This increases the length of the pull rope 7. When the fabric comes into contact with the drive wheel 5 and drives the drive wheel 5 to rotate, the drive wheel 5, under the action of the pull rope 7, causes the cover plate 4 to slide away from the heating tube 3, so that the heat in the heating tube 3 can directly contact the fabric. And because the fabric of this thickness will remain on the conveyor belt 2 and in contact with the drive wheel until the heating is complete. 5. The drive wheel 5 will always remain tilted due to the continuous resistance between them, thus ensuring a stable outflow of heat from the heating tube 3. The adjacent cover plates 4, which are set along the length of the body 1, are connected by a pull rod 8. The distance between the adjacent cover plates 4 is greater than the length of the cover plate 4, so it can be ensured that the cover plate 4 will not cover the adjacent heating tube 3 after sliding, thus ensuring a stable outflow of heat. The pull rope 7 and the pull rod 8 have no elastic deformation properties, so it can be ensured that the pull rope 7 and the pull rod 8 can drive the cover plate 4 to slide in time after the drive wheel 5 rotates, avoiding the time required for the two to undergo elastic deformation before driving the cover plate 4 to slide.

[0023] like Figures 1-3 As shown, several elastic elements 11 are fixedly connected to the inner wall of the machine body 1 on the side away from the feed inlet of the conveyor belt 2. The elastic elements 11 are springs, and the other end of the elastic elements 11 is fixedly connected to the outer peripheral wall of the slide rod 10. The setting of the elastic elements 11 provides the pulling force to reset the cover plate 4. When the drive wheel 5 causes displacement, the elastic element 11 is subjected to the pulling force applied to it by the cover plate 4, thus undergoing tensile deformation. When the drive wheel 5 rotates back to the initial position, the elastic element 11 will reset under the action of its own elastic deformation performance, thereby driving the cover plate 4 back to the initial position to cover the heating tube 3 again. By coating the drive wheel 5, the cover plate 4 and the slide rod 10 with a high-temperature resistant coating, the service life of the structure under high temperature environment for a long time is increased.

[0024] Working principle: When drying thin, quick-drying fabrics, the fabric will pass under the drive wheel 5 without causing it to rotate. At this time, the cover plates 4 are all located directly below the heating tube 3, avoiding direct contact between the high-temperature gas and the fabric. When thicker fabrics pass under the drive wheel 5, the fabric will exert a pushing force on the drive wheel 5, causing it to rotate away from the storage basket. The rotation of the drive wheel 5 will cause the cover plates 4 to move along the slide 9 towards the drive wheel 5. At this time, the high-temperature gas in the heating tube 3 will directly contact the fabric, thus ensuring the comprehensive drying effect on the fabric.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
