Description

Technical Field

[0001] This utility model belongs to the field of diaphragm processing technology, and in particular relates to a diaphragm coating segmented gradient hot air drying oven. Background Technology

[0002] A diaphragm is a rubber product with special properties. Its main function is to isolate and separate two or more substances that are in contact with each other. In order to improve its performance, the diaphragm needs to be coated with a specific coating material during the production process. It also needs to be dried in a hot air drying oven to ensure that the coating is fully cured, remove solvent residues, and improve the performance of the diaphragm.

[0003] However, during the application of hot air drying ovens, the diaphragm is loaded onto a tray fixed inside the oven for drying. When the hot air drying oven is running, there is a temperature difference between the positions closer to the air inlet and the positions farther away, which affects the drying rate of the diaphragm at different positions. This, in turn, affects the performance of the diaphragm coating after drying. There is a technical problem that the diaphragm cannot be continuously rotated and its position adjusted while the high-temperature airflow is homogenized to ensure that the coating on the diaphragm is heated evenly. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a diaphragm-coated segmented gradient hot air drying oven, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0013] Furthermore, the rotating frame is a three-dimensional frame shape, and the cross-section of the rotating frame is square.

[0014] Furthermore, the output end of the electric heating dryer is provided with an air inlet duct, which runs through one side of the drying chamber and is connected to its interior.

[0015] Furthermore, the stabilizing structure includes a support groove and a limiting slide rail. The support groove is located on both sides of the bottom of the rotating frame, and the limiting slide rail is located at the middle position of the bottom of the drying chamber.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0035] Please see Figure 1-8 As shown, this utility model is a segmented gradient hot air drying oven for diaphragm coating, including a drying chamber 1, an electric heating dryer 6 disposed at the middle position on one side of the drying chamber 1, and a rotating frame 2 disposed inside the drying chamber 1, and further including:

[0036] A loading mesh trough 3 is located between the two sides inside the rotating frame 2. Mounting clips 18 are provided on both sides of the loading mesh trough 3. Positioning slots 12 are located on both sides inside the rotating frame 2. The mounting clips 18 fit into the interior of the positioning slots 12. The rotating frame 2 is a three-dimensional frame with a square cross-section. After the diaphragm to be dried is placed in the loading mesh trough 3, the mounting clips 18 are engaged into the positioning slots 12 to install the loading mesh trough 3 between the two sides inside the rotating frame 2. An air inlet duct 4 is provided at the output end of the electric heating dryer 6. The air inlet duct 4 runs through one side of the drying chamber 1 and is connected to its interior. Sealing covers 5 are provided on both sides of the front end of the drying chamber 1. After the diaphragm is placed, the sealing covers 5 are closed. Then, the electric heating dryer 6 is turned on and hot air is blown into the drying chamber 1 through the air inlet duct 4 to dry and cure the diaphragm coating. Digital display thermometers 7 are installed on both sides of the top of the drying chamber 1. At the same time, the temperature inside the drying chamber 1 is measured in real time using the digital display thermometers 7. The air volume of the electric heating dryer 6 is adjusted in stages according to the curing stage of the diaphragm coating, thereby controlling the temperature inside the drying chamber 1 in stages.

[0037] The drive motor 8 is located at the middle position of the top of the drying chamber 1. The rotating frame 2 is located at the middle position of the top of the rotating frame 2. The stabilizing bearing 9 is located at the middle position of the top of the interior of the drying chamber 1. The top of the rotating shaft 10 passes through the interior of the stabilizing bearing 9 and is fixed to the output end of the drive motor 8. When the diaphragm starts drying in the drying chamber 1, the drive motor 8 is started to drive the rotating shaft 10 to rotate the rotating frame 2, thereby driving the diaphragm to rotate continuously and adjust its position in the drying chamber 1.

[0038] A stabilizing structure is provided between the bottom of the rotating frame 2 and the bottom of the drying chamber 1. The stabilizing structure includes a support slide 16 and a limiting slide rail 17. The support slide 16 is located on both sides of the bottom of the rotating frame 2. The support slide 16 is arc-shaped and symmetrically arranged at the bottom of the rotating frame 2. When the rotating frame 2 rotates, the support slide 16 rotates accordingly. The limiting slide rail 17 is located at the middle position of the bottom of the drying chamber 1. The limiting slide rail 17 is annular. The support slide 16 is nested at the top of the limiting slide rail 17 and can slide at the top of the limiting slide rail 17. When the support slide 16 slides on the limiting slide rail 17 as the rotating frame 2 rotates, it supports and stabilizes the rotating frame 2.

[0039] When in use, the drive motor 8, located at the top center of the drying chamber 1, is activated to drive the rotating shaft 10 at its output end to rotate. This causes the rotating frame 2 to rotate inside the drying chamber 1, which in turn causes the diaphragm to rotate horizontally at a uniform speed and change position, ensuring that the diaphragm is heated evenly and that the coating is cured effectively. At the same time, the arc-shaped support grooves 16 located on both sides of the bottom of the rotating frame 2 rotate and slide above the annular limiting slide rail 17 at the bottom of the drying chamber 1, thereby supporting and stabilizing the rotating frame 2 and ensuring the stability of the rotating frame 2 and the diaphragm when they are rotated.

[0040] An adjustment structure is located between the middle positions of the two sides inside the rotating frame 2 and the outer side of the positioning slot 12. The adjustment structure includes a positioning plate 11, an adjustment slot 13, a lifting stud 14, a fastening nut 15, and a limiting plate 19. The positioning plate 11 is fixedly connected to the middle positions of the two sides inside the rotating frame 2. The positioning plate 11 is symmetrically arranged inside the rotating frame 2. An adjustment slot 13 is provided at the middle position inside the positioning plate 11. The lifting stud 14 is located at the middle position of the outer side of the positioning slot 12. The lifting stud 14 penetrates the interior of the adjustment slot 13 and can move up and down inside the adjustment slot 13. The position of the lifting stud 14 penetrating the interior of the adjustment slot 13 is adjusted by raising and lowering it. The position, height, and spacing of the positioning slot 12 inside the rotating frame 2 can be adjusted, thereby adjusting the spacing of the loading mesh slot 3 according to the size. The limiting plate 19 is set at both ends outside the positioning slot 12. The limiting plate 19 is symmetrically arranged outside the positioning slot 12 and is L-shaped. The limiting plate 19 is engaged with the outside of the rotating frame 2 column. When the position of the positioning slot 12 is adjusted by lifting and lowering, the limiting plate 19 moves up and down outside the rotating frame 2 column to limit the positioning slot 12 and ensure that the positioning slot 12 remains horizontal and stable. The fastening nut 15 is set outside the lifting stud 14. After adjusting the positioning slot 12 to a suitable height and spacing, tighten the fastening nut 15 to secure it.

[0041] When in use, loosening the fastening nut 15 on the outside of the lifting stud 14 will drive the lifting adjustment of the positioning slot 12 between the two sides inside the rotating frame 2, so as to adjust the spacing of the loading mesh slot 3 installed between the positioning slots 12 as needed, thereby accommodating diaphragms of different sizes. When adjusting the positioning slot 12, the lifting stud 14 moves up and down inside the adjustment slot 13. At the same time, the limiting plate 19 with "L" shape at both ends on the outside of the positioning slot 12 moves up and down on the outside of the column of the rotating frame 2 to limit the positioning slot 12. After adjusting the positioning slot 12 to the position, tightening the fastening nut 15 on the outside of the lifting stud 14 will make it press against the outside of the positioning plate 11 to stabilize the positioning slot 12.

[0042] Working principle: When using the diaphragm coating segmented gradient hot air drying oven, first adjust the distance between the positioning slot 12 and the two sides inside the rotating frame 2 according to the diaphragm size. At the same time, the lifting stud 14 moves up and down inside the adjustment slot 13, and the limiting plate 19 limits the positioning slot 12 to keep it horizontal and stable. Then tighten the fastening nut 15 to press it against the outside of the positioning plate 11 to stabilize the positioning slot 12. Then place the diaphragm coated with coating material that needs to be dried on the loading mesh trough 3, and insert the installation clip 18 into the positioning slot 12 to install the loading mesh trough 3 between the two sides inside the rotating frame 2. Then close the sealing box cover 5 and open the electric heating dryer 6. Hot air is blown into the drying chamber 1 through the air inlet duct 4 to dry and cure the diaphragm coating. At the same time, the temperature inside the drying chamber 1 is measured in real time using a digital thermometer 7. The air volume of the electric heating dryer 6 is adjusted in stages according to the curing stage of the diaphragm coating, thereby controlling the temperature inside the drying chamber 1 in stages. The drive motor 8 is turned on to drive the rotating shaft 10 to rotate, which in turn drives the rotating frame 2 to rotate inside the drying chamber 1. This causes the diaphragm to rotate horizontally at a uniform speed and change position, so that the coating on the outside of the diaphragm is evenly heated and cured. At the same time, the support slide 16 rotates and slides above the limit slide rail 17 to support and stabilize the rotating frame 2, thereby performing a stable, efficient and uniform diaphragm coating drying and curing operation.

[0043] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
