Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to a drying oven that facilitates loading and unloading. Background Technology

[0002] The emergence of drying ovens is primarily driven by the evolving demand for "controllable drying of materials" in industrial production and scientific research. This has propelled equipment from primitive drying methods to specialized and standardized ones. However, neither of these traditional methods can meet the needs of large-scale mass production, precision material drying, and safe handling of materials with special properties. These inherent defects of traditional methods have spurred the demand for specialized drying equipment that offers "controllable temperature, stable environment, and safe operation."

[0003] While intelligent drying ovens attempt to optimize through electric conveying and intelligent temperature control, new problems have emerged in zirconia drying scenarios: electric components are prone to aging and short circuits under high-temperature environments, resulting in a failure rate far higher than that of purely mechanical structures; sensors and electric systems require regular maintenance and calibration, significantly increasing costs, and they cannot be used during power outages or network interruptions, making them unsuitable for some production environments; their integrated remote control and data recording functions are redundant for the core requirement of batch drying of zirconia, further increasing equipment costs and resulting in low cost-effectiveness; zirconia (especially medical and electronic grades) has stringent cleanliness requirements, and the numerous gaps in the inner liner of general-purpose drying ovens and the cleaning dead zones of electronic components in intelligent drying ovens can easily lead to powder scattering and residue causing cross-contamination; when placing materials inside the drying oven, the trays are not compatible with different oven models, the shelves lack positioning and cushioning structures, small-sized or easily rolling materials are prone to displacement and tipping, and the fixed layer spacing cannot accommodate zirconia products of different heights, requiring equipment replacement and increasing costs. Utility Model Content

[0004] The purpose of this utility model is to provide an oven that facilitates loading and unloading, in order to solve the problems mentioned in the background art, such as the existence of cleaning dead corners, which easily lead to powder scattering and residue causing cross-contamination, the incompatibility of the trays with different oven models when placing materials into the oven, the lack of positioning and buffering structures on the shelves, the easy displacement and tipping of small or easily rolling materials, and the fixed layer spacing, which cannot be adapted to zirconia products of different heights, requiring equipment replacement and increasing costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying oven for easy loading and unloading, comprising a box body, a heating plate fixedly installed inside the box body, a plate groove fixedly installed on the side of the inside of the box body, a guide rail provided at the bottom of the inside of the box body, a telescopic frame movably connected inside the plate groove, a ventilation plate fixedly connected to the back of the box body, a ventilation box fixedly connected to the side of the ventilation plate, a power supply fixedly connected to the outer wall of the ventilation box, a heat insulation box fixedly connected to the outer wall of the box body, a slot fixedly connected to one side of the heat insulation box, a sealing gasket movably connected to the front of the heat insulation box, a moving groove provided on the front of the heat insulation box, a connecting block movably connected inside the moving groove, a plate groove fixedly connected to one side of the connecting block, a vertical rod movably connected to the top of the connecting block, and an adjusting column movably connected to the side of the heat insulation box. Through the combination of "the plate groove movably connected to the telescopic frame + the guide rail at the bottom of the box body," the telescopic frame can be pulled and moved along the plate groove and guide rail, eliminating the need to reach deep into the box to retrieve materials and avoiding burns from touching the high-temperature inner liner; When in operation, the movable groove and connecting block on the front of the insulated box can be used to finely adjust the position of the plate groove (and telescopic frame) to accommodate the handling habits of operators of different heights, reducing the intensity of handling. It is especially suitable for brittle materials such as zirconium oxide, reducing collision cracks caused by improper operation. The height of the plate groove can be adjusted by the connecting block and vertical rod, and fixed with the adjusting column. The layer spacing of the telescopic frame can be flexibly adjusted to accommodate zirconium oxide blanks, crucibles and other materials of different heights without the need to change equipment. As a carrier, the telescopic frame is easier to disassemble and clean than fixed shelves, and the materials can be fixed by structural design (such as adding limiting parts) to prevent material displacement caused by vibration during the operation of the drying oven, thus improving the consistency of batch drying. The ventilation plate on the back of the box works with the ventilation box to guide the hot air to circulate evenly, reducing the local temperature difference in the traditional direct blowing mode. Combined with the stable heating of the heating plate, it can prevent the surface of zirconium oxide materials from rapidly losing water and cracking. At the same time, the insulated box wraps the box body to reduce heat loss and improve energy efficiency, while the sealing gasket strengthens the sealing performance after the box door is closed, ensuring stable temperature inside the box and further ensuring drying quality.

[0006] Furthermore, a connecting plate is movably connected inside the ventilation box, and a fan is fixedly connected to the other side of the connecting plate. The fan is electrically connected to a power source. The movable connection between the connecting plate and the ventilation box (such as a buckle, slide rail, etc.) allows for easy disassembly or adjustment of the fan's position, facilitating fan inspection, cleaning, and replacement, reducing later maintenance costs, and preventing fan failure from affecting the overall operation of the drying oven. The fixed connection between the connecting plate and the fan prevents the fan from shifting due to vibration during operation, ensuring continuous and stable fan operation. The direct electrical connection between the fan and the power source reduces line loss, provides a more stable power supply, and efficiently drives airflow. Combined with the ventilation plate on the back of the drying oven, it accelerates the circulation of hot air inside the oven, avoids uneven local temperature, and improves the drying effect.

[0007] Furthermore, a hinge is fixedly connected to the front of the heat insulation box, and a through hole is provided on the front of the hinge. A screw is fixedly connected to one side of the through hole. The fixed connection between the hinge and the heat insulation box provides stable support for the door (or movable panel). With the screw in the through hole for tightening, the hinge can be prevented from loosening, ensuring that the structure does not shift when the door is opened and closed for a long time, and that the operation is smooth and without jamming.

[0008] Furthermore, a door is fixedly connected to the other side of the hinge, and a caster wheel is fixedly connected to the bottom of the door. The hinge provides rotational support for the door, and the caster wheel converts the sliding friction of the door into rolling friction. Even heavy insulated doors can be easily pushed and pulled open and closed, reducing the physical exertion of operators, and is especially suitable for scenarios with frequent loading and unloading.

[0009] Furthermore, a slot is fixedly connected to one side of the cabinet door, and a latch is movably connected inside the slot. In the locked state, the latch can prevent the cabinet door from being opened accidentally, preventing the high-temperature hot air from leaking out and scalding the operator during the drying process, or affecting the temperature environment inside the cabinet due to the sudden opening of the door, thus providing safety for equipment operation and personnel operation.

[0010] Furthermore, the bottom of the insulated box is fixedly connected with foot pads, and the side of the insulated box is fixedly connected with a control panel. An adjustment knob is movably connected to the other side of the control panel. The foot pads at the bottom of the insulated box can increase the friction with the ground and prevent the oven from shifting due to vibration during operation. At the same time, they can buffer the direct contact between the equipment and the ground, reduce vibration transmission, protect the ground and the bottom structure of the equipment, and improve the overall placement stability. The control panel on the side integrates adjustment functions. With the movably connected adjustment knob, the operator can directly and quickly fine-tune drying parameters such as temperature and air speed through the knob without having to frequently bend over or touch high-temperature areas. The operation is intuitive and labor-saving, and it is suitable for the dynamic adjustment needs of parameters during the drying process.

[0011] Furthermore, the interior of the tray is movably connected to a telescopic frame, and the front of the tray is movably connected to a fixing buckle. The telescopic frame is movably connected to the tray, allowing it to freely stretch or shrink according to the material size, flexibly expanding or shrinking the placement area. This adapts to both layered drying of small materials and large workpieces, improving the oven's adaptability to materials of different specifications. 3. Secure locking ensures drying safety: The fixing buckles on the front of the tray can be fastened and locked after the telescopic frame is adjusted into place, preventing the telescopic frame from shifting or sliding out due to equipment vibration during the drying process, ensuring stable placement of materials, avoiding collision damage, and maintaining smooth airflow inside the chamber to ensure uniform drying.

[0012] Furthermore, the guide rail is internally connected to a slag-receiving tray, which can be pushed and pulled directly in and out along the guide rail. It can accurately collect the debris, residue, or drips that fall from the material during the drying process, preventing impurities from accumulating at the bottom of the chamber or near the heating components, reducing cleaning dead corners, and timely collection of residue can prevent it from clogging the guide rail, affecting the sliding of the telescopic frame, or causing local overheating due to residue accumulation near the heating plate. This protects the core components of the equipment, maintains a clean environment inside the chamber, prevents impurities from contaminating the material, and ensures the drying effect.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This oven facilitates loading and unloading, offering high efficiency and convenience. Its adaptability is strong, with a telescopic frame and a fixed buckle connecting the movable joint to the tray. The load-bearing space can be flexibly adjusted according to material size, and the frame can be pulled out and pushed along the tray. Combined with the guide rails at the bottom of the oven, it significantly reduces the difficulty of loading and unloading materials, making it especially suitable for heavier or differently sized workpieces. The oven door uses hinges and casters for effortless opening and closing, and can be flexibly positioned after opening without occupying operating space, further improving loading and unloading efficiency. 2. This easy-to-load drying oven ensures stable drying quality, excellent energy efficiency, and high safety. The heating plate provides a stable heat source, while the ventilation plate, ventilation box, and adjustable fan work together to accelerate air circulation within the oven and prevent uneven temperature distribution. The insulated box and sealing gasket reduce heat leakage, maintain a constant temperature inside the oven, and lower energy consumption. Simultaneously, the insulated box isolates high temperatures, the feet ensure equipment stability, and the latch locks the door to prevent accidental opening and heat leakage, comprehensively ensuring drying quality and operational safety. 3. This oven is easy to load and unload, simple to maintain and clean, and highly durable. The slag tray can be easily pulled out along the guide rail, making it easy to clean material residue and avoid the accumulation of impurities that may affect the operation of the equipment. The fan is movably connected to the ventilation box through the connecting plate. The modular design of components such as hinges and telescopic frames means that the overall structure does not need to be disassembled during maintenance and replacement, reducing maintenance costs. The combination of fixed and movable connections for each component ensures the stability of the core functions and extends the overall service life of the equipment. Attached Figure Description
