Description

Technical Field

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

[0002] Drying ovens are widely used in various industries such as processing and manufacturing, chemicals, food, and pharmaceuticals for drying materials. During the operation of a drying oven, the opening and closing of the oven lid is a necessary step for materials to enter and exit the oven body, and the rationality of its structural design directly affects production efficiency, operational safety, and the service life of the equipment.

[0003] Currently, most existing drying oven lid-opening devices rely on manual operation. This method is not only labor-intensive but also inefficient, making it unsuitable for large-scale production. Some mechanically assisted lid-opening devices are complex in structure, have poor stability, and are prone to malfunctions during long-term use, increasing equipment maintenance costs. Furthermore, some lid-opening devices lack effective guiding and supporting structures during lid movement, leading to uneven movement, jamming, or even misalignment. This not only affects opening efficiency but may also pose safety hazards. Additionally, existing lid-opening devices suffer from unstable power transmission and uneven force distribution on the cylinders in their connection and drive mechanisms, further reducing the reliability and lifespan of the device.

[0014] 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.

[0015] like Figure 1-2 As shown, the drying oven has an opening device. The drying oven includes a furnace body 1. A feed inlet 2 is located on one side of the upper end of the furnace body 1, and a discharge outlet 3 is located on the other side. A feed cover 4 is located at the feed inlet 2, and a discharge cover 5 is located at the discharge outlet 3. The opening device includes a feed cylinder 6 and a discharge cylinder 7. Slide rails 8 are provided on both sides of the feed inlet 2 and both sides of the discharge outlet 3. The inner side of each slide rail 8 has a pulley groove 9. Slide rails 9 are also provided on both sides of the feed cover 4 and both sides of the discharge cover 5. A pulley 10 is rotatably connected to the feed furnace cover 4 or the discharge furnace cover 5. The pulley 10 is located in the corresponding pulley groove 9. A cylinder seat 11 is fixedly connected to the upper end of the furnace body 1. The feed cylinder 6 and the discharge cylinder 7 are respectively hinged to the cylinder seat 11. Cylinder push plates 12 are fixedly connected to the feed furnace cover 4 and the discharge furnace cover 5, respectively. The output shaft of the feed cylinder 6 is hinged to the cylinder push plate 12 on the feed furnace cover 4, and the output shaft of the discharge cylinder 7 is hinged to the cylinder push plate 12 on the discharge furnace cover 5. When the cylinder is working, the output shaft extends or retracts, pushing or pulling the cylinder push plate 12, thereby driving the feed furnace cover 4 and the discharge furnace cover 5 to move, realizing the opening and closing of the furnace cover. When the furnace cover is driven by the cylinder, the pulley 10 rolls in the pulley groove 9, thereby driving the furnace cover to slide along the slide rail 8, realizing the opening and closing movement of the furnace cover.

[0016] As a preferred embodiment of the above technical solution, at least two pairs of pulleys 10 are installed on the feeding furnace cover 4. One pair of pulleys 10 is rotatably mounted on one end of the feeding furnace cover 4 via bearings, and the other pair of pulleys 10 is rotatably mounted on the other end of the feeding furnace cover 4 via bearings. Similarly, at least two pairs of pulleys 10 are installed on the discharging furnace cover 5. One pair of pulleys 10 is rotatably mounted on one end of the discharging furnace cover 5 via bearings, and the other pair of pulleys 10 is rotatably mounted on the other end of the discharging furnace cover 5 via bearings. The two pairs of pulleys 10 can evenly distribute the weight of the furnace cover, ensuring its balance.

[0017] As a preferred embodiment of the above technical solution, the slide rail 8 includes a front half 13 and a rear half 14 connected in sequence. The rear half 14 is located on both sides of the feed inlet 2 or the discharge outlet 3. A notch 15 connecting the front half 13 and the rear half 14 is provided at the connection point, connecting to the pulley groove 9. An inclined plate 16 is provided at the notch 15. An inclined section 17 is formed by bending the end of the rear half 14 away from the front half 13 downwards. An inclined groove 18 connecting to the pulley groove 9 is provided at the inclined section 17. When the front pulley 10 moves with the furnace cover to the notch 15, the inclined plate 16 guides the pulley 10 to descend a certain height. At this time, the rear pulley enters the inclined groove 18 at the inclined section 17, realizing the descent of the feed furnace cover 4 or the discharge furnace cover 5, thereby tightening the furnace cover. The design of the inclined section 17 and the inclined groove 18 facilitates the furnace cover to return to its position more smoothly with the help of gravity when closed, and also helps the pulley 10 to slide smoothly out along the inclined groove 18 when the furnace cover is opened.

[0018] As a preferred embodiment of the above technical solution, the hinge between the feeding cylinder 6 and the cylinder seat is located in the middle of the feeding cylinder 6, and the hinge between the discharging cylinder 7 and the cylinder seat is located in the middle of the discharging cylinder 7.

[0019] As a preferred embodiment of the above technical solution, the feeding cylinder 6 and the discharging cylinder 7 are staggered. This avoids interference between the two cylinders during operation and ensures that each operates independently and normally.

[0020] It is worth mentioning that the technical features such as cylinders involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using 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 elaborate further.

[0021] 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. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
