Description

Technical Field

[0001] This utility model relates to the field of oven technology, and in particular to an automatic door opening and closing device for a large aging chamber. Background Technology

[0002] A high-temperature aging test chamber is a specialized instrument used to test the service life and stability of items under high-temperature environments. It is primarily used for product quality testing in fields such as electronics, electrical engineering, communications, power, automotive, and aerospace, and its test results directly affect product quality and lifespan. In large-scale aging chamber applications, the doors are often hinged doors, which, due to space limitations, are prone to collisions with products during use. Furthermore, traditional manual door opening and closing methods are inefficient, inconvenient to operate, and pose safety hazards, especially in situations requiring frequent door opening and closing. Manual operation not only increases labor costs but may also affect production efficiency. Additionally, the sealing of manual doors is difficult to guarantee, potentially affecting the stability of temperature and humidity inside the chamber. Existing technologies include some automatic door devices using electric push rods or chain drives, but these suffer from complex structures, difficult maintenance, and high operating noise.

[0003] Chinese patent application number 202221532279.4 discloses a side-sliding door opening and closing device for a vacuum oven, including an oven frame, a door assembly, a door side-sliding mechanism fixed to the oven frame, a door tensioning mechanism, and a door docking mechanism. The door docking mechanism connects the door to the door side-sliding mechanism and the door tensioning mechanism respectively to realize the side-sliding and closing of the door. This side-sliding door opening and closing device for a vacuum oven, using a side-opening design, improves the stability of the equipment and can be applied to relatively large vacuum baking equipment, saving space.

[0004] However, the following technical problems still exist in its practical application:

[0005] The device contains multiple complex components and mechanisms, such as the door side-moving mechanism, the door tensioning mechanism, and the door docking mechanism. The coordinated operation of these mechanisms requires precise control and debugging, which increases the difficulty and cost of manufacturing and maintenance. Due to the large number of components and the complex structure, problems such as component wear and loosening may occur, affecting the side-moving and closing effect of the door, and thus affecting the overall stability of the equipment. The oven only has two doors, which limits the flexible use of the internal space of the oven and cannot meet the needs of using the oven in separate zones. When the oven processes multiple different process requirements or different materials at the same time, it is difficult to achieve effective spatial isolation and temperature control, thus affecting the utilization efficiency and process flexibility of the oven. In addition, it may also lead to uneven heat loss, increase energy consumption, and may adversely affect the overall temperature distribution inside the oven, thereby affecting product quality and production efficiency. Utility Model Content

[0026] like Figure 1-6The large aging chamber automatic door opening and closing device shown includes a support frame 1, a chamber body 2, and a door body. The chamber body 2 is mounted on the support frame 1, and a heating device 3 is installed on the chamber body 2. The support frame 1 is provided with two sets of door opening and closing drive devices, each including a door opening and closing drive assembly and a door tightening drive assembly. The door opening and closing drive assembly is located at one end of the support frame 1 and drives the door body. The door body includes a first door body 4 and a second door body 5. The door opening and closing drive assembly drives the first door body 4 and the second door body 5 to move closer to or further away from each other. The first door body 4 and the second door body 5 are slidably mounted on a load-bearing beam 6 and a guide beam 7 via a sliding assembly. The door tightening drive assemblies are respectively located at both ends of the support frame 1 and drive the load-bearing beam 6 and the guide beam 7 to move closer to or further away from the chamber body 2.

[0027] In this embodiment, two guide beams 7 are arranged between two load-bearing beams 6. Specifically, the two guide beams 7 are located at the upper and lower ends of the support frame 1, and the two guide beams 7 are located in the middle of the support frame 1.

The second gear 10 is connected to one end of the drive shaft 11. The other end of the drive shaft 11 passes through the support frame 1 and one end of the load-bearing beam 6 and is connected to the drive wheel 12. The driven wheel 13 is mounted on the other end of the load-bearing beam 6. A synchronous belt 14 is installed between the drive wheel 12 and the driven wheel 13. A first synchronous belt connector 15 and a second synchronous belt connector 16 are connected to both sides of the synchronous belt 14, respectively. The first synchronous belt connector 15 is connected to the first door body 4 via a first connecting plate 17, and the second synchronous belt connector 16 is connected to the second door body 5 via a second connecting plate 18.

[0029] The sliding assembly includes a linear guide rail 19 and a slider 20. The linear guide rail 19 is installed on the load-bearing beam 6 and the guide beam 7 respectively. The slider 20 is slidably installed on the linear guide rail 19.

[0030] In this embodiment, a linear guide rail and synchronous belt drive mechanism are used, which makes the door move smoothly and accurately during opening and closing, improving the stability of the entire aging chamber equipment. It also occupies less space, which helps to optimize the space layout around the aging chamber, improve space utilization, and has a compact structure and reasonable component layout, making it easy to maintain and repair daily.

[0031] The door tightening drive assembly includes a mounting frame 21, a cylinder 22, a drive plate 23, and a load-bearing shaft 25. The mounting frame 21 is mounted on the support frame 1, and the cylinder 22 is mounted on the mounting frame 21. The telescopic rod of the cylinder 22 is connected to the vertically arranged drive plate 23. The upper and lower ends of the drive plate 23 are respectively connected to the load-bearing shaft 25 through the first connector 24. One load-bearing shaft 25 passes through the support frame 1 and is connected to the load-bearing beam 6 through the second connector 26. The other load-bearing shaft 25 passes through the support frame 1 and is connected to the guide beam 7.

[0032] Mounting bracket 21 includes two mounting plates 211 and a load-bearing connecting plate 212. The two mounting plates 211 are symmetrically mounted on the crossbeam of the support frame 1. The load-bearing connecting plate 212 is vertically mounted between the two mounting plates 211. Cylinder 22 is installed in the middle of the load-bearing connecting plate 212. The telescopic rod of cylinder 22 passes through the load-bearing connecting plate 212 and connects to the vertical drive plate 23.

[0033] Two linear bearings 27 are respectively installed on the ends of the two mounting plates 211 that are far apart from each other. The two linear bearings 27 are respectively sleeved on the load-bearing shaft 25 and slide in cooperation with the load-bearing shaft 25.

The controller controls the door opening and closing operation, which is simple and convenient to operate. It realizes the automation of the aging chamber door opening and closing process, greatly reduces the need for manual intervention, reduces labor intensity, and improves work efficiency.

[0035] The working principle of this utility model's automatic door opening and closing device for a large aging chamber is as follows: When the aging chamber door needs to be opened, the cylinder 22 is activated. The cylinder 22 drives the drive plate 23 to move closer to the load-bearing connecting plate 212. Through the connecting piece 24, the load-bearing shaft 25 moves along the linear bearing 27. The upper and lower load-bearing shafts 25 pass through the support frame 1, respectively driving the load-bearing beam 6 and the guide beam 7 away from the chamber body 2. This, in turn, drives the first door body 4 and the second door body 5 away from the chamber body 2, creating a certain gap between them. At this time, the servo motor 15 starts to drive the drive wheel 12. The drive wheel 12 drives the synchronous belt 14 to move, which in turn drives the first synchronous belt connector 15 and the second synchronous belt connector 16 to move away from each other. The first synchronous belt connector 15 and the second synchronous belt connector 16 respectively drive the first door body 4 and the second door body 5 to move on the linear guide rail 19, realizing the opening function of the door. When the door needs to be closed, the above steps are reversed.

[0036] This utility model discloses an automatic door opening and closing device for a large aging chamber. Through the coordinated action of a cylinder and a servo motor, it enables the rapid and automatic opening and closing of the large aging chamber door. The application of the servo motor makes the door movement more precise and efficient, reducing unnecessary energy consumption. Compared with the traditional manual door opening and closing method, it reduces the need for manual operation, lowers labor costs, and isolates operators from hazardous environments, reducing operational risks, improving operational safety, and increasing work efficiency. On production lines with long-term continuous operation, it helps enterprises save operating costs and improve economic benefits.

[0037] The aging chamber has two sets of doors, upper and lower, which can be opened and closed as needed for aging tests. This design allows for flexible use of the internal space of the aging chamber, meeting the requirements for zoned use. When processing multiple different processes or materials simultaneously, the aging chamber can effectively achieve spatial isolation and temperature control, thereby improving its efficiency and process flexibility. Its structure ensures uniform heat distribution within the aging chamber, reducing energy consumption and improving product quality and production efficiency. In case of malfunction, maintenance personnel can quickly locate and repair the problem, reducing downtime and improving equipment availability. This device is not only suitable for large aging chambers but can also be adjusted to adapt to different specifications and types of aging chamber equipment, making it applicable to a wider range of industrial sectors.

[0038] The above description, in conjunction with preferred technical solutions, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of the utility model is limited to these descriptions. For those skilled in the art, simple deductions and substitutions can be made without departing from the concept of this utility model, and all such modifications and substitutions should be considered within the scope of protection of this utility model.
