Technical Field

[0001] This utility model belongs to the field of drying oven technology, specifically relating to the opening mechanism of a single drying oven. Background Technology

[0002] Individual drying ovens, as important equipment for drying various individual materials, are widely used in many fields. With the continuous development of production processes, the performance requirements for individual drying ovens are also increasing. Among them, the opening and closing operation of the oven lid is a key link in the use of the drying oven, which directly affects the efficiency, safety and drying effect of the equipment.

[0003] Currently, the opening mechanisms of common single-unit drying ovens on the market have several problems. Some opening mechanisms are manually operated, requiring operators to expend considerable physical effort and time to open or close the oven lid, resulting in low work efficiency and safety hazards such as burns from operating in the high-temperature environment inside the oven. Some electric or pneumatic opening mechanisms have inadequate structural designs and complex transmission component layouts, leading to high maintenance difficulty and susceptibility to failure during long-term use, affecting the continuity of production. In addition, for large-volume single-unit drying ovens, a large furnace opening is required to accommodate the entry and exit of large workpieces, and the single large furnace lid requires a large operating space during automatic opening and closing.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] like Figure 1-2 As shown, the opening mechanism of a single-unit drying oven includes a furnace body 1, with a furnace opening 2 at the upper end of the furnace body 1, and a furnace cover 3 covering the furnace opening 2. The opening mechanism includes a cylinder 4, which is hinged to the furnace body 1. The output shaft of the cylinder 4 is hinged to a linkage rod 5, and one end of the linkage rod 5 is fixedly connected to a drive shaft 6. Both ends of the drive shaft 6 are rotatably connected to the furnace body 1. A main connecting rod 7 and a secondary connecting rod 8 are respectively provided on both sides of the furnace cover 3. One end of the main connecting rod 7 is hinged to the furnace cover 3, and the other end is fixedly connected to the drive shaft 6. One end of the secondary connecting rod 8 is hinged to the furnace cover 3, and the other end is hinged to the furnace body 1. When the cylinder 4 is activated, the output shaft of the cylinder 4 extends or retracts, driving the linkage rod 5 hinged to it to move. The movement of linkage 5 drives the fixedly connected transmission shaft 6 to rotate. The rotation of transmission shaft 6 causes one end of the main connecting rod 7, which is fixedly connected to it, to rotate around transmission shaft 6. Since the other end of the main connecting rod 7 is hinged to the furnace cover 3, and the other side of the furnace cover 3 is hinged to the furnace body 1 through the auxiliary connecting rod 8, the furnace cover 3 opens and closes with the hinge point between the auxiliary connecting rod 8 and the furnace body 1 as the fulcrum under the drive of the main connecting rod 7. Through the simple cylinder 4 drive and linkage transmission, the automatic opening and closing of the furnace cover 3 is realized. Compared with manual opening, it greatly reduces the labor intensity of operators, improves the efficiency and accuracy of opening the cover, and also reduces the safety risks of manual operation in high-temperature environments.

[0018] As a preferred embodiment of the above technical solution, there are two furnace covers 3 and two sets of opening mechanisms, arranged opposite each other. With two furnace covers 3 and two sets of oppositely arranged opening mechanisms, during operation, both sets of mechanisms operate simultaneously, driving the two furnace covers 3 to open and close synchronously. The double furnace cover 3 design reduces the area of ​​a single furnace cover 3, thereby reducing the operating space required during its opening and closing. The two sets of oppositely arranged opening mechanisms ensure that the opening and closing actions of the two furnace covers 3 are consistent, making the opening and closing of the furnace covers 3 smoother and further improving the reliability and stability of the furnace cover 3 opening and closing.

[0019] As a preferred embodiment of the above technical solution, the linkage 5, main linkage 7, auxiliary linkage 8, and cylinder 4 are all located outside the furnace body 1. This external location prevents these components from being affected by the high-temperature environment inside the furnace. External placement facilitates routine inspection, maintenance, and repair of these components, reducing maintenance costs and difficulty. Simultaneously, it reduces thermal damage to the components, extends their service life, and improves the reliability and stability of the entire opening mechanism.

[0020] As a preferred embodiment of the above technical solution, the number of auxiliary connecting rods 8 is one, and the auxiliary connecting rod 8 is arranged parallel to the main connecting rod 7. The parallel arrangement of the auxiliary connecting rod 8 and the main connecting rod 7 can provide stable support for the furnace cover 3, prevent the furnace cover 3 from shaking or tilting during the opening and closing process, ensure a good fit between the furnace cover 3 and the furnace opening 2, improve the sealing performance of the furnace body 1, reduce the leakage of hot air during the drying process, and help improve the drying effect and energy utilization rate.

[0021] As a preferred embodiment of the above technical solution, the upper ends of the furnace body 1 are respectively provided with support parts 9 on both sides, and the support parts 9 are located below the furnace cover 3. The support parts 9 can provide support and limit the furnace cover 3 in both the open and closed states, and at the same time make the closing of the furnace cover 3 more stable, further improving the sealing performance of the furnace body 1.

[0022] As a preferred embodiment of the above technical solution, a target assembly 10 is installed at the upper end of the furnace body 1.

[0023] As a preferred embodiment of the above technical solution, a heat exchanger 10 and a heater 11 are installed inside the furnace body 1. The heat exchanger 10 achieves heat transfer and recovery by exchanging heat with the air or materials inside the furnace; the heater 11 converts electrical energy or other energy sources into heat energy to heat the furnace and bring it to the required drying temperature. The combined use of the heat exchanger 10 and the heater 11 can effectively improve energy utilization, reduce energy consumption, and ensure the uniformity and stability of the temperature inside the furnace, providing a good drying environment for the materials and helping to improve the drying effect and product quality.

[0024] It is worth mentioning that the technical features of the cylinder, target assembly, heat exchanger and heater involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0025] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort.
