Description

Technical Field

[0001] This utility model belongs to the technical field of door flap equipment, specifically relating to a door flap device for a vacuum dehumidifier. Background Technology

[0002] A vacuum rehumidifier is a specialized piece of equipment that utilizes a vacuum physical environment combined with steam / water mist humidification and heating technology to rapidly, uniformly, and deeply heat and humidify tobacco leaves. It plays a crucial role in "awakening" and "softening" tobacco leaves during tobacco processing and is an essential piece of equipment for ensuring the quality of subsequent processing, reducing losses, and improving the quality of the final cigarette product.

[0003] The vacuum dehumidifier includes a housing with a side-opening door that matches the housing's inlet and outlet. To ensure that the material rack can be smoothly pushed into the housing through the inlet and outlet, a corresponding support frame needs to be installed in front of the housing's inlet and outlet. Due to the side-opening door, there is a certain gap between the support frame and the housing. To ensure that the material rack can smoothly enter the housing, a door-front flap device needs to be installed at the inlet and outlet of the housing to support the material rack at a certain interval. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a door flap device for a vacuum dehumidifier that can support the material rack.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a door flap device for a vacuum dehumidifier, comprising a housing, a support plate rotatably connected to the housing; a movable frame slidably connected inside the housing, an opening wheel rotatably connected to the movable frame that can drive the support plate to rotate; a plurality of stabilizing wheels rotatably connected to the movable frame, and a plurality of force-bearing blocks respectively cooperating with the plurality of stabilizing wheels fixedly connected to the support plate.

[0006] Furthermore, a cylinder is fixedly connected inside the housing, and the telescopic end of the cylinder is fixedly connected to the moving frame.

[0007] Furthermore, the telescopic end of the cylinder is fixedly connected to a threaded post, the movable frame is provided with a through hole corresponding to the threaded post, and a nut for fixing the movable frame is screwed onto the threaded post.

[0008] Furthermore, the movable frame is rotatably connected to a support wheel that engages with the bottom of the housing.

[0009] Furthermore, the force-bearing block includes an inclined portion that cooperates with the stabilizing wheel, and a stabilizing portion is connected to the inclined portion.

[0010] Furthermore, the housing is provided with a hinge that cooperates with the support plate, and the rotation center of the hinge is located below the support plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In use, this utility model uses a movable frame, opening wheels, stabilizing wheels, and force-bearing blocks to make the support plate open to a certain angle under the action of the opening wheels. Then, with the cooperation of the stabilizing wheels and force-bearing blocks, the support plate is rotated to a horizontal state, so that the top surface of the support plate is flush with the top surface of the shell. This allows the support plate to support the material rack, so that the material rack can smoothly enter the chamber of the vacuum dehumidifier. Attached Figure Description

[0018] A door flap device for a vacuum dehumidifier, such as Figure 1-4 As shown, the device includes a box body 1, a side door 2 that cooperates with the inlet and outlet of the box body 1, and a door-front flap device 3 that supports the material rack at the inlet and outlet of the box body 1. The door-front flap device 3 includes a housing 4, a support plate 5 rotatably connected to the housing 4, a movable frame 7 slidably connected inside the housing 4, an opening wheel 9 rotatably connected to the movable frame 7 that can drive the support plate 5 to rotate, and multiple stabilizing wheels 11 rotatably connected to the movable frame 7. Multiple force-bearing blocks 10 that cooperate with the multiple stabilizing wheels 11 are fixedly connected to the support plate 5.

[0019] When this utility model is in use, during the loading of the vacuum rehumidifier, the movable frame 7 slides along the shell 4. The movable frame 7 drives the support plate 5 to rotate upward along the shell 4 via the opening wheel 9. As the movable frame 7 slides, the stabilizing wheel 11 contacts the force-bearing block 10, causing the support plate 5 to rotate to a horizontal state, making the top surface of the support plate 5 flush with the top surface of the shell 4, so that the support plate 5 can support the material rack, allowing the material rack to smoothly enter the housing 1 of the vacuum rehumidifier. When the side door 2 opens and closes, the movable frame 7 moves in the opposite direction, causing the stabilizing wheel 11 and the opening and closing wheel to move away from the support plate 5. The support plate 5 rotates downward under the action of gravity, leaving space for the movement of the side door 2.

[0020] Furthermore, a cylinder 6 is fixedly connected inside the housing 4, and the telescopic end of the cylinder 6 is fixedly connected to the movable frame 7; preferably, as shown in the example. Figure 2 As shown, a pair of cylinders 6 are provided to ensure the stability of the movement of the moving frame 7.

[0021] Furthermore, the telescopic end of the cylinder 6 is fixedly connected to a threaded post, and the movable frame 7 is provided with a through hole corresponding to the threaded post. A nut for fixing the movable frame 7 is screwed onto the threaded post. The movable frame 7 is fixed by the cooperation of the threaded post and the nut, so that the movable frame 7 and the cylinder 6 are detachably connected, making this application convenient for maintenance and replacement.

[0022] Furthermore, the movable frame 7 is rotatably connected to a support wheel 8 that engages with the bottom of the housing 4. The support wheel 8 supports the movement of the movable frame 7, thereby improving the stability of the movable frame 7.

[0023] Furthermore, the force-bearing block 10 includes an inclined portion that cooperates with the stabilizing wheel 11, and a stabilizing portion is connected to the inclined portion; by setting the inclined portion, the stabilizing wheel 11 can smoothly contact the stabilizing portion of the force-bearing block 10, so as to improve the stability of the rotation of the support plate 5.

[0024] Furthermore, the housing 4 is provided with a hinge that cooperates with the support plate 5, and the rotation center of the hinge is located below the support plate 5. By setting the hinge below the support plate 5, when the support plate 5 is rotated to a horizontal state, the end of the support plate 5 near the housing 4 contacts the housing 4, thereby limiting the position of the support plate 5 and improving the stability of the support plate 5.
