Description

Technical Field

[0001] This utility model belongs to the field of drying equipment technology, specifically relating to a hot air dryer with uniform drying function. Background Technology

[0002] Hot air dryers are devices that use the principle of heat pumps and sensible heat exchange technology to provide high-temperature hot air. They are widely used in the printing industry and are more energy-efficient than traditional electric heating. In the production and processing of paper tubes, since paper tubes are tubular objects made of multiple layers of paper, hot air drying is required during the processing to make the paper tubes more compact.

[0003] A prior art patent, CN220103568U, describes a hot air dryer with uniform drying function. This patent includes a support frame, with a body fixedly mounted on its upper surface. One end of the body extends to the lower surface of the support frame. A connecting pipe is fixedly mounted at the output end of the body, and one end of the connecting pipe is connected to an air outlet plate. An expansion assembly is provided on the inner wall of the air outlet plate. By using this expansion plate assembly, a drive motor rotates a rotating rod on the inner wall of a limiting sleeve, and a moving rod moves the expansion plates to the two side walls of the air outlet plate. The expansion plate allows for semi-enclosed drying of paper tubes, improving the uniformity of the hot air dryer. The expansion plate is also adjustable, enabling the dryer to use paper tubes of different sizes, further enhancing its applicability. However, in practical use, the following shortcomings remain: Firstly, the patent cannot adjust the air outlet height during drying, reducing applicability. Secondly, the air outlet position remains constant throughout the drying process, failing to create a uniform reciprocating drying operation, thus reducing drying efficiency and uniformity.

[0004] Therefore, a hot air dryer with uniform drying function is needed to solve the problems of the inability to adjust the drying air outlet height and the inability to adjust the drying air outlet direction in the existing technology. Utility Model Content

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

[0021] Please see Figure 1-4 This utility model provides a hot air dryer with uniform drying function, including a support frame 1, a dryer body 2 and an air outlet plate 3. The dryer body 2 is fixedly installed on the support frame 1. A connecting mechanism 5 is provided on the upper part of the air outlet plate 3. The air outlet plate 3 is connected to the bottom of the dryer body 2 through the connecting mechanism 5. A height adjustment mechanism 4 is connected to the air outlet plate 3. The height adjustment mechanism 4 is fixedly connected to the support frame 1. An air outlet adjustment mechanism 6 is also provided on the air outlet plate 3.

[0022] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the height adjustment mechanism 4 includes two fixed plates 401, which are symmetrically fixedly connected to the left and right sides of the dryer body 2. A motor 402 is fixedly installed on the upper part of the left fixed plate 401, and a threaded rod 403 is fixedly connected to the bottom of the motor 402. A support plate 404 is rotatably connected to the bottom of the threaded rod 403. The support plate 404 is fixedly connected to the support frame 1. A connecting plate 406 is threadedly connected to the threaded rod 403. One side of the connecting plate 406 is connected to the air outlet plate 3. A guide rod 405 is fixedly connected to the bottom of the right fixed plate 401, and another connecting plate 406 is slidably connected to the guide rod 405.

[0023] In use, the motor 402 runs, causing the threaded rod 403 to rotate, which in turn causes the air outlet plate 3 to move threadedly on the threaded rod 403 via the connecting plate 406, thereby adjusting the height of the air outlet plate 3. This allows the drying height of the air outlet plate 3 to be adjusted according to the drying process, improving its applicability. Furthermore, the guide rod 405 enhances the stability of the sliding adjustment of the air outlet plate 3.

[0024] Specifically, the connecting plate 406 and the air outlet plate 3 are fixedly connected by bolts, and the connecting plate 406 is provided with a threaded hole that matches the threaded rod 403. The connecting plate 406 on the right guide rod 405 is provided with a through sliding hole, and a self-lubricating bearing is embedded in the hole to ensure smooth sliding between the guide rod 405 and the connecting plate 406.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the connecting mechanism 5 includes an inner connecting pipe 501 and an outer connecting pipe 502. The bottom of the inner connecting pipe 501 is fixedly connected to and communicates with the top of the air outlet plate 3. The outer connecting pipe 502 is slidably sleeved outside the inner connecting pipe 501. The top of the outer connecting pipe 502 is fixedly connected to the bottom of the dryer body 2. A sealing ring is provided between the inner connecting pipe 501 and the outer connecting pipe 502. The sliding of the inner connecting pipe 501 and the outer connecting pipe 502 facilitates their extension and retraction adjustment.

[0026] As can be seen from the above working process, by setting the height adjustment mechanism 4 and cooperating with the connecting mechanism 5, the air outlet height of the air outlet plate 3 can be adjusted according to the drying conditions when the air outlet plate 3 is used for drying, thereby improving the drying efficiency and thus improving the applicability of the device.

[0027] Further as Figure 2 , Figure 3 and Figure 4As shown, it is worth noting that the air outlet adjustment mechanism 6 includes a guide plate 601 and a rotating shaft 602. The rotating shaft 602 is fixedly connected to the top of the guide plate 601. The guide plate 601 is rotatably set inside the bottom of the air outlet plate 3 via the rotating shaft 602. Multiple guide plates 601 are set inside the air outlet plate 3. A gear 603 is fixedly connected to the left end of the rotating shaft 602. A fixing frame 604 is set outside the gear 603. The fixing frame 604 is fixedly connected to the left surface of the air outlet plate 3. A sliding groove 605 is opened at the bottom of the fixing frame 604. A rack 606 is slidably set inside the fixing frame 604 via the sliding groove 605. The rack 606 is meshed with the gear 603. A connecting block 607 is fixedly connected to the left side of the rack 606. The connecting block 607 is set outside the fixing frame 604 via the sliding groove 605. An electric telescopic rod 608 is fixedly connected to the rear side of the connecting block 607. The electric telescopic rod 608 is fixedly installed on the surface of the fixing frame 604.

[0028] In use, the electric telescopic rod 608 is operated, causing the connecting block 607 to slide. This causes the rack 606 to slide back and forth in the slide groove 605. As the rack 606 slides, it drives the gear 603 to rotate, which in turn drives the rotating shaft 602 to rotate. This causes the guide plate 601 to rotate back and forth at the bottom of the air outlet plate 3. Thus, the guide plate 601 can be used to adjust the drying airflow, thereby improving the uniformity of the drying process.

[0029] This solution has the following working process: When this device is in use, the hot air generated by the operation of the dryer body 2 is delivered to the air outlet plate 3 through the connecting mechanism 5. The air outlet plate 3 performs the drying air output. The operation of the motor 402 causes the threaded rod 403 to rotate, thereby adjusting the height of the air outlet plate 3 by moving the connecting plate 406 along the threaded rod 403. This allows the drying height of the air outlet plate 3 to be adjusted according to the drying process, improving its applicability. Furthermore, the guide rod 405 improves the stability of the sliding adjustment of the air outlet plate 3. The sliding of pipe 501 and external connecting pipe 502 facilitates their telescopic adjustment. Simultaneously, the operation of electric telescopic rod 608 causes the connecting block 607 to slide, which in turn causes rack 606 to slide back and forth in slide groove 605. The sliding of rack 606 causes rack 606 to drive gear 603 to rotate, which in turn causes gear 603 to drive shaft 602 to rotate, which in turn causes guide plate 601 to rotate back and forth at the bottom of air outlet plate 3. Thus, guide plate 601 can achieve reciprocating adjustment of drying air, thereby improving the uniformity of drying work.

[0030] In summary: By using the height adjustment mechanism 4 in conjunction with the connecting mechanism 5, the air outlet height of the air outlet plate 3 can be adjusted according to the drying conditions during the drying process, thereby improving drying efficiency and the applicability of the device. By using the air outlet adjustment mechanism 6, the air outlet position of the air outlet plate 3 can be reciprocated according to the drying process. This reciprocating drying process avoids a fixed drying position and improves the uniformity of the drying process.
