Description

Technical Field

[0001] This utility model relates to the field of sample drying technology, and in particular to an electric heating forced-air drying oven. Background Technology

[0002] Electric heating drying ovens are commonly used instruments and equipment that use electric heating to conduct air circulation drying tests. After the paint production is completed, it is necessary to test the paint's adhesion and anti-aging properties. Before testing, the paint needs to be coated on a plastic or metal plate for drying. Existing heating plates are prone to developing stains on their surface after prolonged use, which reduces the heating plate's efficiency and makes it unsuitable for use.

[0003] The prior art patent application with authorization publication number CN222104112U discloses an electric heating forced-air drying oven, including a base, an oven connected to the base, and a heating component connected to the oven. The heating component includes a heating plate, a fixing plate, and a fixing screw. The heating plate is connected to the oven and is snapped onto the fixing plate. The fixing screw connects the heating plate to the fixing plate. The arrangement of the heating plate, fixing plate, and fixing screw facilitates the disassembly and cleaning of the heating mechanism, avoiding the situation where the heating plate is prone to stains after prolonged use and the heating plate's working efficiency is reduced due to lack of cleaning for a long time.

[0004] However, in the aforementioned prior art, the surface temperature of the dried metal plate is high, making it difficult to remove. People are easily burned when they put their hands into the chamber, which affects the use by testing personnel. Utility Model Content

Detailed Implementation

[0018] Please see Figures 1 to 4 ,in, Figure 1 This is a structural schematic diagram of the electric heating forced-air drying oven of this utility model. Figure 2 This is a front view of the electric heating forced-air drying oven of this utility model. Figure 3 This is the utility model Figure 2 AA-line sectional view, Figure 4 This is the utility model Figure 2 BB line section view.

[0019] This utility model provides an electric heating forced-air drying oven, including a box body 101, a box cover 102, and an adjustment and connection unit. The adjustment and connection unit includes a base frame 103, an arc-shaped rail 104, a base 105, a push rod 106, a rotating plate 107, a fixing rod 108, a stepper motor 109, a drying component, and a feeding component. The drying component includes a heating chamber 110, a blower 111, a heating wire 112, an exhaust pipe 113, a central intelligent control block 114, and a temperature sensor 115. The feeding component includes a side plate 116, multiple symmetrical right-angle plates 117, and a limiting rod 118. The box body 101 has an arc-shaped groove 119.

[0020] The cover 102 is hinged to the body 101 and located on one side of the body 101. The adjusting connection unit is connected to the body 101. The body 101 has an arc-shaped groove 119, which slides with the arc-shaped rail 104. The base frame 103 is fixedly connected to the arc-shaped rail 104 and located above it. The base 105 is fixedly connected to the base frame 103 and located on one side of it. The stepper motor 109 is connected to... The housing 101 is detachably connected and located below the housing 101. The rotating plate 107 is fixedly connected to the stepper motor 109 and located at the output end of the stepper motor 109. The fixing rod 108 is fixedly connected to the rotating plate 107 and located above the rotating plate 107. The push rod 106 is rotatably connected to the fixing rod 108 and the base 105 respectively. The feeding assembly is located above the base frame 103. The drying assembly is connected to the housing 101.

[0021] In this embodiment, the metal plate coated with paint is placed on the feeding assembly, and the lid 102 is closed using a hinge. The drying assembly is then activated to heat and dry the interior of the box 101. After processing, the stepper motor 109 is activated, driving the rotating plate 107 to rotate. Through the linkage of the fixing rod 108, the push rod 106, and the base 105, the arc-shaped rail 104 slides along the arc-shaped groove 119, driving the base frame 103 to move out of the box 101. The drying assembly provides high-temperature gas to heat the chamber formed by the box 101 and the lid 102, ensuring the drying of the metal plate. This method of removing the processed metal plate avoids the need for inspectors to reach in to collect it, reducing the risk of burns and facilitating operation for inspectors.

[0022] Furthermore, the heating chamber 110 is connected to the housing 101 and located above the housing 101; the blower 111 is fixedly connected to the heating chamber 110 and located above the heating chamber 110; the heating wire 112 is fixedly connected to the heating chamber 110 and located on the inner wall of the heating chamber 110; and the exhaust pipe 113 is connected to the housing 101 and located below the housing 101.

[0023] In this embodiment, the blower 111 draws in air from the outside and sends it into the heating chamber 110. The heating wire 112 on the inner wall of the heating chamber 110 is energized and heats up, heating the incoming air into a hot airflow. The hot airflow enters the interior of the housing 101 along the connecting path and acts directly on the metal plate to achieve heating and drying. At the same time, the exhaust pipe 113 below the housing 101 continuously discharges the moisture and exhaust gas generated inside due to drying. The output end of the exhaust pipe 113 is close to the input end of the blower 111, thus forming an airflow circulation and improving the drying efficiency.

[0025] In this embodiment, the central intelligent control block 114 is based on existing technology and is used to start and stop the stepper motor 109. The temperature sensor 115 is used to sense the temperature inside the housing 101, which facilitates operation by the testing personnel.

[0026] Furthermore, the side plate 116 is fixedly connected to the base frame 103 and is located above the base frame 103, and a plurality of symmetrical right-angle plates 117 are fixedly connected to the side plate 116 respectively and are located on one side of the side plate 116 respectively.

[0027] In this embodiment, the side plate 116 and the symmetrical right-angle plate 117 are used to place the metal plate coated with paint, achieving simple support. The structure is simple and easy for testing personnel to operate and use.

[0028] Furthermore, the limiting rod 118 is fixedly connected to the side plate 116 and is located on one side of the side plate 116, and the limiting rod 118 is slidably engaged with the housing 101.

[0029] In this embodiment, the limiting rod 118 is used to limit the distance the side plate 116 can move, thereby reducing the occurrence of safety incidents.

[0030] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this application, still fall within the scope of this application.
