Description

Technical Field

[0001] The utility model relates to the technical field of bellows, and particularly relates to a suction component with a flap box structure. Background Art

[0002] At present, the existing bellows generally have the function of adjusting the flow rate of the air inlet, mainly by controlling the cross-sectional area of the air inlet through a pull-type sealing plate, so as to control the air volume. However, the traditional pull-type sealing plate generally moves up and down in the chute. Since the sealing plate is long-term at the air inlet and is affected by the wind pressure, the sealing plate will be deformed, and the deformed sealing plate has the problem of difficult sliding. Therefore, there is an urgent need for a suction component with a flap box structure. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, this solution provides a suction component with a flap box structure to solve the problem that the traditional pull-type sealing plate inside the bellows generally moves up and down in the chute. Since the sealing plate is long-term at the air inlet and is affected by the wind pressure, the sealing plate will be deformed, and the deformed sealing plate has the problem of difficult sliding.

[0004] To solve the above technical problems, the utility model provides the following technical solutions: A suction component with a flap box structure includes a box body. A sealing valve plate is rotatably arranged inside the box body. An air-operated unit for driving the sealing valve plate to rotate is arranged on one side of the box body. The air-operated unit includes a cylinder arranged on one side of the box body. A connecting seat is rotatably connected to the output shaft of the cylinder. The upper end of the connecting seat is fixedly connected with the upper end of the sealing valve plate through a connecting shaft.

[0010] By means of the above technical solution, the present utility model provides a suction component with a flap-type box structure, which at least has the following beneficial effects:

[0011] 1. The suction component with a flap-type box structure adopts a box structure as a whole, and drives a sealing valve plate through a cylinder to control the opening and closing of the air inlet of the box, ensuring an effective suction area and avoiding the problem that the pull-type suction mechanism is prone to deformation and difficult to move after long-term operation.

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] In order to solve the problem that the traditional pull-out sealing plate inside the bellows generally moves up and down in the chute. Since the sealing plate is under wind pressure at the air inlet for a long time, the sealing plate will be deformed, and it is difficult to slide after deformation. In combination with Figures 1 - 3 As shown in the figure, the present utility model provides: a flap-type box structure air suction assembly, including a box body 1. An outer edge is integrally formed on the end face of the box body 1. A plurality of mounting holes are installed on the outer edge for the overall installation. Two connecting shafts 303 are rotatably installed inside the upper end of the box body 1. A same sealing valve plate 2 for controlling the on-off of the box body 1 is connected between the two connecting shafts 303. An air cylinder unit 3 for driving the sealing valve plate 2 to rotate is installed on one side of the box body 1. The air cylinder unit 3 includes an air cylinder 301 installed on one side of the box body 1. The bottom of the air cylinder 301 is connected to the box body 1 through a hinge seat 4. At the same time, a connecting seat 302 is rotatably connected to the output shaft of the air cylinder 301. The connecting seat 302 is fixedly connected to the upper end of the sealing valve plate 2 through the connecting shaft 303. During operation, the output shaft of the air cylinder 301 extends to make the connecting seat 302 rotate, thereby driving the connecting shaft 303 to rotate, so that the sealing valve plate 2 can rotate and open around the air inlet of the box body 1. And the opening degree of the box body 1 is controlled according to the telescopic length of the air cylinder 301. When the air flows through the inclined or horizontal sealing valve plate 2, compared with the traditional pull-out sealing plate, the wind resistance generated is smaller, effectively avoiding the problem that the traditional pull-out sealing plate is deformed after long-term use and is difficult to slide and open.

[0023] Embodiment 2

[0024] In order to facilitate understanding whether there are foreign objects at the air inlet of the box body 1, on the basis of Embodiment 1, as Figure 4As shown, a protective net 5 is installed at the port of the box body 1 through bolts. A detection unit 6 for detecting foreign object blockage is movably installed on the protective net 5. The detection unit 6 includes a slide rail 601 fixedly arranged on the upper part of the box body 1. A bracket 602 is connected to the slide rail 601. The bracket 602 is movably installed on the surface of the protective net 5. An infrared emitter 603 and an infrared receiver 604 are respectively installed at the upper and lower ends of the bracket 602. The infrared signals emitted by the infrared emitter 603 and the infrared receiver 604 across the upper and lower ends of the protective frame move horizontally back and forth along the protective frame. When sundries adhere to the protective frame due to negative pressure, the infrared signals will be blocked by foreign objects and cannot conduct, resulting in signal interruption, so that the external control terminal can receive this signal and give a warning to the staff.

[0025] In order to enable the infrared emitter 603 and the infrared receiver 604 to move automatically back and forth horizontally on the surface of the protective frame, a screw rod is rotatably installed on the slide rail 601. A slider is threadedly installed on the screw rod. The slider is slidably installed on the slide rail 601. One end of the bracket 602 is fixedly connected to the slider. And a drive motor connected to the screw rod is installed at one end of the slide rail 601. By controlling the rotation of the screw rod by the drive motor, the slider moves horizontally on the slide rail 601, driving the infrared emitter 603 and the infrared receiver 604 on the bracket 602 to move.

[0026] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.

[0027] It should be noted that in this article, terms such as "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
