Abstract
Description
Technical Field
[0001] This application relates to the field of drying technology, specifically a sealing component drying device. Background Technology
[0002] In the fields of machinery manufacturing, automotive parts and hydraulic equipment, seals made of materials such as rubber and polyurethane are key components for ensuring the airtightness of equipment.
[0003] These types of seals often have residual release agent or moisture after processing and molding, and need to be dried to meet the usage standards.
[0004] For example, patent CN214223601 U discloses a sealing component processing and drying device. This patent uses hot air to blow the sealing component while repeatedly tossing it up with a shaking and tossing mechanism to increase its contact area with the hot airflow, thereby accelerating the drying process.
[0005] However, if the sealing material is exposed to cold air immediately after being dried at high temperature, it is prone to micro-cracks due to thermal stress. Therefore, it needs to be left to stand in a closed environment for a period of time after drying, and then taken out after the temperature gradient has leveled off. Existing equipment is usually designed as a single station, so the oven is idle during the standing period, resulting in insufficient equipment utilization and severely limited daily production capacity.
[0006] Therefore, it is necessary to provide a sealing component drying device to solve the above problems.
[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention
[0008] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a sealing component drying device, which solves the problem that the drying oven is idle during the static period, resulting in insufficient equipment utilization and severely limited daily production capacity.

[0017] A sealing plate, which is installed at both ends of the tray;
[0018] A cylinder is installed on both sides of the drying chamber, and the output end of the cylinder is fixedly connected to both sides of the sealing plate.
[0019] Furthermore, the tray has multiple sets of mounting holes at each placement station.
[0020] Furthermore, the tray has heat-conducting holes arranged in a ring around the mounting hole.
[0021] Furthermore, a sealing plate is provided on the other side of the two sets of placement stations on the tray.
[0022] Furthermore, the sealing plate is located outside the drying chamber, while the sealing plate is located inside the drying chamber.
[0023] The beneficial effect of this application is that the sealing component drying device provided by this application achieves the effect of being switchable by setting two sets of identical placement stations.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0035] like Figures 1-2 As shown, the sealing component drying device provided in this application is mainly used in industrial production scenarios. It can be fixedly installed on the workshop floor or workbench and is specifically used for efficient drying of sealing components made of materials such as rubber and silicone. Specifically, the drying device includes a base 1 and a drying mechanism 2 set on the upper end of the base 1. The drying mechanism 2 includes a drying box 20 fixedly set on the upper end of the base 1. The drying box 20 is made of double-layer stainless steel plate, and high-temperature resistant insulation cotton 25 is filled between the two layers of plates, which can reduce heat loss and thus achieve the effect of maintaining a constant temperature environment inside the box.
[0036] To achieve the active heating function, two sets of heating wires 22 are installed at the top and bottom of the drying oven 20. The terminals of the heating wires 22 extend through the side wall of the drying oven 20 to the outside, and are connected to the temperature control power supply (not shown in the figure) via cables.
[0037] It should be noted that the heating wire 22 covers the bottom and top of the drying chamber 20, so that the heat radiation covers the entire drying space. In order to accelerate the heat circulation, a fan 21 is provided at the bottom and top of the drying chamber 20 at one end of the heating wire 22. The air outlet of the fan 21 is directly facing the area of the heating wire 22. So when the fan 21 is started, the airflow pushes the heat generated by the heating wire 22 forward, thereby achieving the effect of diffusing the heat source.
[0038] To buffer the high-speed airflow and prevent the airflow from blowing directly onto the seal, baffles 23 are provided at the bottom and top of the drying oven 20 at the other end of the heating wire 22. The surface of the baffles 23 is evenly provided with air holes 24, thereby reducing the wind speed to prevent the seal from shifting and allowing the hot airflow to diffuse evenly through the air holes 24.
[0039] In order to enable continuous drying operations, such as Figures 1-4 As shown, multiple sets of movable and switchable drying sections 3 are provided inside the drying oven 20. Specifically, the drying section 3 includes multiple sets of crossbeams 31 provided inside the drying oven 20. At the same time, grooves 32 are provided at both ends of the crossbeams 31, and guide rods 33 are slidably arranged in the grooves 32. A tray 35 is fixedly arranged on the guide rod 33. The tray 35 is used to place the sealing component, so that the guide rod 33 can be slid along the groove 32 by pushing the tray 35.
[0040] It should be noted that the tray 35 has two sets of placement stations 350 of the same size at both ends. Each placement station 350 has multiple sets of mounting holes 353 for vertically inserting the seals to be dried. In order to improve the heat conduction efficiency, heat conduction holes 352 are provided in a ring around each mounting hole 353, so that the hot airflow can penetrate the tray 35 to heat the seals in three dimensions.
[0041] To enable workstation switching, multiple sets of through holes 30 are opened at the center of both ends of the drying oven 20. The height of the through holes 30 matches the thickness of the tray 35, and the width is greater than that of a single placement workstation 350.
[0042] Furthermore, a sealing plate 34 is fixedly installed on one side of the two end placement stations 350 at both ends of the tray 35. The sealing plate 34 is always installed outside the drying oven 20, and the outer dimensions of the sealing plate 34 are larger than the cross-section of the through hole 30, so as to facilitate the subsequent sealing operation of the through hole 30.
[0043] Meanwhile, cylinders 36 are fixedly installed on both sides of the outside of the drying oven 20. The output end of the cylinder 36 is connected to the outer side of the sealing plate 34. When the cylinder 36 extends or retracts, it can drive the tray 35 to move axially along the guide rod 33, so that the two placement stations 350 alternately enter and exit the drying chamber.
[0044] It should be noted that a sealing plate 37 is provided on the other side of the two placement stations 350 on the tray 35. The sealing plate 37 is always located inside the drying chamber 20 and matches the size of the through hole 30. So that after the tray 35 is switched, it cooperates with the sealing plate 34 to block the through holes 30 at both ends of the drying chamber 20 and ensure the airtightness of the drying chamber 20.
[0045] Initially, cylinder 36 is in the retracted position, exposing one set of placement stations 350 of tray 35 to the outside of drying chamber 20. The operator inserts the seal to be dried into the mounting hole 353 of this station. Then, cylinder 36 is activated to push tray 35 towards the inside of drying chamber 20. When this placement station 350 is fully inside drying chamber 20, sealing plate 34 precisely closes the side through hole 30. Simultaneously, the other set of placement stations 350 moves out of drying chamber 20, and the through hole 30 at the other end is sealed by sealing plate 37. The system is then sealed. At this time, the heating wire 22 and fan 21 are activated to dry the first set of seals. After drying, the system automatically shuts off and enters the settling stage. During this settling period, the operator can fill a new batch of seals at the external placement station 350. When the first set of seals has finished settling, the cylinder 36 retracts to move the placement station 350 out for unloading, and at the same time pushes the already loaded placement station 350 into the drying position. This cycle is repeated to achieve parallel operation of the drying and settling processes, thereby improving the utilization rate of the equipment.
[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
