Description

Technical Field

[0001] This utility model relates to the field of autoclave door switch technology, and in particular to an automatic autoclave door switch device. Background Technology

[0002] In autoclave equipment widely used in building materials, chemical industries, and other fields, the automatic opening and closing device of the autoclave door is a key component to ensure production efficiency and safety. Traditional autoclave door opening and closing control typically relies on the cooperation of a limit plate and a limit groove for positioning. Its core structure is as follows: a limit plate is set on the outer ring of the door, and a corresponding annular limit groove is set at the front end of the tank. An opening for the limit plate to enter and exit is opened on the end face of the limit groove. During the opening process, the door is first driven to rotate by a first power mechanism, aligning the limit plate with the opening of the limit groove. Then, a second power mechanism drives the door to flip outward along the hinge point, completing the opening action.

[0003] However, this dual-power mechanism design has significant drawbacks: First, two independent power systems (such as hydraulic cylinders and motor reducers) significantly increase equipment manufacturing costs and complicate installation and maintenance. Second, automatic control requires precise coordination of the timing of the two mechanisms; for example, the opening mechanism must only start after the rotating mechanism has completely retracted from the limit plate, otherwise mechanical jamming or power overload may occur. In practical applications, maintaining such precise timing control is difficult over a long period, and signal delays can easily lead to malfunctions, affecting production continuity. Furthermore, the layout of multiple power sources occupies equipment space and reduces the overall structural compactness. Therefore, an automatic autoclave door opening and closing device is urgently needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic opening and closing device for autoclave doors, which can realize the rotation and opening of the autoclave door with only one motor. It is simple and quick to operate, easy to maintain, and highly practical.

[0005] The present invention adopts the following technical solution: An automatic autoclave door opening and closing device includes an autoclave tank, a door at the front end of the tank, a drive plate driven by a motor on the tank, and the door being rotatably mounted on the drive plate by a drive component driven by the motor. Limit plates are spaced apart around the outer circumference of the door, and an annular limit groove is provided at the front end of the tank. An opening for the limit plates to enter and exit is formed on the end face of the limit groove. During operation, the motor first drives the drive component to control the rotation of the door, and then drives the drive plate to open the door.

[0006] Preferably, the drive plate is L-shaped, a set of support plates is provided on one side of the tank, and a drive shaft is provided at the end of the drive plate, with the drive shaft rotatably disposed between the support plates.

[0007] Preferably, the driving component includes a driven grooved wheel disposed on the driving plate, the driven grooved wheel being coaxially disposed with the vessel door via a connecting shaft, a driving grooved wheel being disposed at the end of the driving plate away from the driven grooved wheel, a transmission rope being disposed between the driving grooved wheel and the driven grooved wheel, a first driven gear being coaxially disposed on the driving grooved wheel, a first driving gear being rotatably disposed on the driving plate, and the first driving gear being a non-full-tooth gear, initially meshing with the first driven gear; a main bevel gear being disposed on the rotating shaft driven by the motor, and an auxiliary bevel gear meshing with the main bevel gear being coaxially connected to the first driving gear.

[0008] Preferably, a second driving gear is provided on the rotating shaft, and the second driving gear is a non-full-tooth gear. A second driven gear is provided on the drive shaft. When the vessel door is closed, the second driving gear and the second driven gear disengage. When the vessel door rotates and the limiting plate is located in the slot, the second driving gear and the second driven gear engage and contact.

[0009] Preferably, the width of the limiting plate is smaller than the width of the slot.

[0010] Preferably, both the rotating shaft and the drive shaft are rotatably connected to the support plate via bearings.

[0011] Preferably, the drive plate is provided with a receiving groove on one side arranged radially along the vessel door, the driving groove wheel and the driven groove are both located in the receiving groove, and a maintenance plate is detachably provided on the drive plate outside the receiving groove.

[0012] Preferably, the inspection plate and the drive plate are connected by bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By using a single motor to drive the drive component and the drive plate simultaneously and sequentially, this utility model eliminates the need for two independent power mechanisms (such as additional hydraulic cylinders, motor reducers, etc.) in the traditional solution, reducing the number of power components and the setting of related supporting pipelines and control systems, and significantly reducing the manufacturing cost of the equipment; at the same time, due to the reduction in the number of components, the subsequent installation, debugging and maintenance operations are also simpler, reducing maintenance costs and workload.

[0014] Because the same motor is used to complete the rotation of the autoclave door (aligning the limit plate with the slot) and the opening of the autoclave door in sequence, the stringent requirements of the traditional dual-power mechanism on the timing of the two mechanisms are avoided. This reduces the risk of mechanical jamming and power overload caused by signal delays and timing mismatches, ensuring the continuity and stability of the autoclave door automatic opening and closing process and improving the reliability of equipment operation.

[0016] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments: like Figures 1 to 3 As shown, the automatic opening and closing device for the autoclave door 2 of this utility model includes an autoclave tank 1, an autoclave door 2 at the front end of the tank 1, a limit plate 3 at intervals around the outer ring of the autoclave door 2, and an annular limit groove at the front end of the tank 1. A slot 4 for the limit plate 3 to enter and exit is opened on the end face of the limit groove. A drive plate 5 is provided on the tank 1, and the drive plate 5 is driven by a motor 6 to open and close the autoclave door 2. The autoclave door 2 is rotatably mounted on the drive plate 5 by a drive component, which is driven by the motor 6 to rotate the autoclave door 2 to adjust the position of the limit plate 3 and the slot 4. When the autoclave door 2 needs to be opened, the limit plate 3 is positioned inside the slot 4. When the autoclave door 2 is closed, the autoclave door 2 is rotated after the limit plate 3 is inside the slot 4, so that the limit plate 3 and the slot 4 are relatively offset. During operation, the motor 6 first drives the drive component to control the rotation of the autoclave door 2 to move the limit plate 3 towards the slot 4, achieving the correspondence between the limit plate 3 and the slot 4. Subsequently, the motor 6 drives the drive plate 5 to open the autoclave door 2. This invention eliminates the need for complex timing coordination control of two sets of power mechanisms. The automatic opening and closing of the vessel door 2 can be achieved simply by controlling the operating state of a single motor 6 (such as forward and reverse rotation). This simplifies the logic design of the control system, reduces the complexity of the control program, and facilitates operation and debugging.

[0017] Furthermore, the drive plate 5 is L-shaped, and a set of support plates 7 is provided on one side of the tank body 1. A drive shaft 8 is fixedly provided at the end of the drive plate 5, and the drive shaft 8 is rotatably disposed between the support plates 7 via bearings. In this embodiment, the drive component includes a driven grooved wheel 9, which is rotatably disposed on the drive plate 5 via a connecting shaft. The connecting shaft passes through the drive plate 5 and is coaxially fixedly connected to the vessel door 2. A drive grooved wheel 10 is provided at the end of the drive plate 5 away from the driven grooved wheel 9. A transmission rope 11 is provided between the drive grooved wheel 10 and the driven grooved wheel 9. The drive grooved wheel 10 is rotatably disposed on the drive plate 5 via a connecting shaft. A first driven gear 12 is coaxially disposed on the connecting shaft after it passes through the drive plate 5. A first drive gear 13 is also rotatably disposed on the drive plate 5. The first drive gear 13 is a non-full-tooth gear. In the initial state, the first drive gear 13 meshes with the first driven gear 12. A main bevel gear 1 is provided on the rotating shaft 16 driven by the motor 6. 4. The first driving gear 13 is coaxially connected to the auxiliary bevel gear 15, which meshes with the main bevel gear 14. The rotating shaft 16 is rotatably mounted between the upper and lower support plates 7 via bearings. The motor 6 is connected to the rotating shaft 16 via a coupling. During operation, the motor 6 drives the rotating shaft 16 to rotate, and the main bevel gear 14 meshes with the auxiliary bevel gear 15 for transmission, thereby driving the first driving gear 13 to rotate. The first driving gear 13 meshes with the first driven gear 12 to rotate, driving the driven grooved wheel 9 to rotate. Under the drive of the driven grooved wheel 9, the driving grooved wheel 10 drives the vessel door 2 to rotate until the teeth on the first driving gear 13 disengage from the tooth grooves on the first driven gear 12. At this time, the limiting plate 3 is located in the slot 4. At this time, the control motor 6 continues to work to open the vessel door 2.

[0018] Furthermore, a second driving gear 17 is provided on the rotating shaft 16, and the second driving gear 17 is a non-full-tooth gear. A second driven gear 18 is provided on the drive shaft 8. When the vessel door 2 is closed, the second driving gear 17 and the second driven gear 18 disengage. As the vessel door 2 rotates and the limiting plate 3 is located in the slot 4, the second driving gear 17 and the second driven gear 18 engage and contact. The teeth on the first driving gear 13 disengage from the tooth grooves on the first driven gear 12. At this time, the vessel door 2 gradually opens under the drive of the motor 6. Since the maximum opening degree of the vessel door 2 is ninety degrees, and since the offset of the limiting plate 3 relative to the slot 4 is only a few degrees, when the second driving gear 17 meshes with the second driven gear 18 to drive the drive plate 5 to move and complete the opening of the vessel door 2, the first driving gear 13 will not contact and mesh with the first driven gear 12. That is, the vessel door 2 will not rotate during this process. When it is necessary to close the door, the control motor 6 is flipped, and the vessel door 2 is closed. As the limiting plate 3 enters the receiving slot 19, the first driving gear 13 meshes with the first driven gear 12 to drive the vessel door 2 to rotate and enter the limiting slot. The limiting plate 3 disengages from the slot 4, completing the positioning and installation of the vessel door 2. The entire operation can be achieved with just one motor 6, eliminating the need for two independent power mechanisms (such as additional hydraulic cylinders, motor 6 reducers, etc.) in the traditional solution. This reduces the number of power components and the setup of related pipelines and control systems, significantly lowering the manufacturing cost of the equipment. At the same time, due to the reduction in the number of components, the subsequent installation, debugging, and maintenance operations are also simpler, reducing maintenance costs and workload.

[0019] Furthermore, in this embodiment, the width of the limiting plate 3 is smaller than the width of the slot 4, so as to provide a certain margin for the movement of the vessel door 2 and avoid the slot 4 being too small to affect the opening and closing of the vessel door 2. The rotating shaft 16 and the drive shaft 8 are both rotatably connected to the support plate 7 through bearings. In addition, a receiving groove 19 is provided on one side of the drive plate 5 arranged radially along the vessel door 2. The driving groove wheel 10 and the driven groove are both located in the receiving groove 19. A maintenance plate 20 is detachably provided on the drive plate 5 outside the receiving groove 19. The maintenance plate 20 is connected to the drive plate 5 by bolts to facilitate its inspection and maintenance and improve the convenience of operation.
