Technical Field

[0001] This utility model relates to the field of cleanroom paper production technology, and in particular to a drying device for cleanroom paper production. Background Technology

[0002] Cleanroom paper is a type of paper product with unique physical properties, including high liquid absorption, high oil absorption, and good softness. It is widely used in electronics, medical, food and other fields. Drying is a key step in the production process of cleanroom paper. Drying it in a hot air tunnel drying oven can remove moisture from the pulp and bring the cleanroom paper to the specified moisture content.

[0003] Currently, existing hot air tunnel drying ovens use conveyor belts to transport materials during operation. However, after processing, the conveyor belts remain exposed, easily accumulating dust, fibers, paper scraps, and other debris. This debris not only affects the cleanliness of the conveyor belts but may also adhere to the cleanroom paper products during the next operation of the drying oven, affecting product quality. Therefore, we propose a drying device for cleanroom paper production to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drying device for dust-free paper production.

[0006] A drying device for dust-free paper production includes a support base, a conveyor belt installed inside the support base, a drying chamber fixedly connected above the support base, and cover plates symmetrically distributed at both ends of the drying chamber. Fixing blocks are fixedly connected to the front and rear ends of the cover plates on opposite sides. A motor is fixedly connected to the side of the fixing block on the back side, and a rotating shaft is fixedly connected to the output end of the motor. The rotating shaft passes through the inner wall of the fixing block and is connected to the inner wall of another set of fixing blocks via a bearing. A second protective plate is sleeved on the outer side of the rotating shaft. An abutment block is fixedly connected to the side of the cover plate, and a threaded rod is inserted inside the abutment block. A rotating block is fixedly connected to the end of the threaded rod. A slot is provided on the side of the drying chamber.

[0007] Preferably, a connecting block is fixedly connected to the inner wall of the cover plate, and a slider groove adapted to the connecting block is opened on the side of the drying box.

[0008] Preferably, the inner wall of the slot is adapted to the outer wall of the threaded rod, and the slots are distributed at equal intervals from top to bottom on the side wall of the drying oven.

[0009] Preferably, the outer surface of the threaded rod is provided with external threads, and the inner wall of the slot is provided with internal threads.

[0010] Preferably, the outer wall of the second protective plate is attached with a rubber sheet, and the rubber sheet is configured with an L-shaped structure.

[0011] Preferably, there are two sets of connecting blocks and slider grooves, and the two sets of connecting blocks and slider grooves are symmetrically distributed about the central axis of the drying box.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This device is equipped with a cover plate and a second protective plate. During use, the cover plate and the second protective plate work together to protect the drying box after processing, thereby effectively preventing the adhesion of foreign matter, ensuring the cleanliness of the drying box, and ensuring the subsequent production quality of dust-free paper.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A drying device for cleanroom paper production includes a support base 1, a conveyor belt 2 installed inside the support base 1, a drying chamber 3 fixedly connected above the support base 1, and cover plates 4 symmetrically distributed at both ends of the drying chamber 3. The support base 1, conveyor belt 2, and drying chamber 3 are components of a hot air tunnel drying oven. Their specific working principles and connection methods are existing technologies and will not be described in detail here. Fixing blocks 5 are fixedly connected to the front and rear ends of the cover plates 4 on opposite sides. A motor 6 is fixedly connected to the side of the back fixing block 5, and the motor 6 can drive the rotating shaft 7 to rotate in both directions. The rotation, achieved by starting the motor 6, allows the second protective plate 8 to be flipped. When the device is in use, raising the second protective plate 8 can effectively ensure the normal conveying of the dust-free paper. The output end of the motor 6 is fixedly connected to the rotating shaft 7, which passes through the inner wall of the fixed block 5 and is connected to the inner wall of another set of fixed blocks 5 through a bearing. The second protective plate 8 is sleeved on the outside of the rotating shaft 7. The side of the cover plate 4 is fixedly connected to the abutment block 12, and the inside of the abutment block 12 is inserted with a threaded rod 13. The end of the threaded rod 13 is fixedly connected to the rotating block 14. The side of the drying box 3 is provided with a slot.

[0022] Furthermore, refer to Figure 3 It can be seen that the inner wall of the cover plate 4 is fixedly connected with the connecting block 9, and the side of the drying oven 3 is provided with a slider groove 10 that is compatible with the connecting block 9. The cross-section of the connecting block 9 and the slider groove 10 is set as a T-shaped structure, which can realize the stable up and down movement of the cover plate 4.

[0023] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the inner wall of the slot is compatible with the outer wall of the threaded rod 13. The slots are distributed at equal intervals from top to bottom on the side wall of the drying oven 3. By opening multiple sets of slots, the height of the cover plate 4 can be flexibly adjusted, thereby meeting the conveying needs of dust-free paper of different thicknesses.

[0024] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the outer surface of the threaded rod 13 is provided with external threads, and the inner wall of the slot is provided with internal threads. The internal and external threads are not shown in the figure. Through the threaded engagement of the threaded rod 13 and the slot, the positioning effect of the threaded rod 13 on the abutment block 12 can be effectively guaranteed.

[0025] Furthermore, refer to Figure 1 and Figure 2It can be seen that the outer wall of the second protective plate 8 is attached with a rubber plate 11, and the rubber plate 11 is set with an L-shaped structure. The rubber plate 11 with the L-shaped structure can protect the outer wall of the second protective plate 8.

[0026] Furthermore, refer to Figure 3 It can be seen that there are two sets of connecting blocks 9 and slider grooves 10, and the two sets of connecting blocks 9 and slider grooves 10 are symmetrically distributed about the central axis of the drying box 3. Through the cooperation of the two sets of connecting blocks 9 and slider grooves 10, the stable up and down movement of the cover plate 4 can be further guaranteed.

[0027] Working Principle: When using this utility model, the operator can first place the device in a suitable position. During the idle period, the two sets of cover plates 4 and the second protective plate 8 work together to cover and protect the conveyor belt 2, which is always exposed, thus effectively preventing the adhesion of debris. When the device needs to be used to dry the dust-free paper, the operator can first start the motor 6 through the controller, which will cause the rotating shaft 7 and the second protective plate 8 to rotate 90 degrees, so that the second protective plate 8 and the cover plate 4 are in contact. Then, the operator can rotate the rotating block 14 in sequence to drive the threaded rod 13 to rotate and pull it out from the slot opened on the side of the drying box 3. Then, the operator can lift the cover plate. The cover plate 4 is used to adjust the distance between the bottom of the cover plate 4 and the conveyor belt 2 according to the thickness of the lint-free paper. After adjusting to the appropriate position, the operator can rotate the rotating block 14 again, so that the threaded rod 13 is inserted into the inside of the abutment block 12 and embedded in the corresponding slot on the side of the drying box 3, so as to realize the quick positioning of the cover plate 4 and effectively slow down the heat loss rate inside the drying box 3. Then the operator can put the lint-free paper to be dried onto the conveyor belt 2. Then, by starting the conveyor belt 2, the lint-free paper can be driven into the inside of the drying box 3 for drying. After drying, the lint-free paper can be sent out from the other side opening of the drying box 3. The above is the entire working principle of this utility model.
