Description

Technical Field

[0001] This utility model relates to the technical field of air duct openings, specifically to an angle-adjustable air duct opening structure. Background Technology

[0002] Adjustable air vents are ventilation components that allow for flexible control of airflow direction and coverage by adjusting the vent's outlet angle. They are widely used in air conditioning systems, industrial ventilation, automotive air conditioning, laboratory ventilation, and other scenarios. Their core function is to break the limitation of fixed air vents' "one-way airflow," adjusting the airflow direction according to actual needs to improve ventilation efficiency.

[0003] Chinese Patent CN217101729U discloses a conveying device for ABS flame-retardant masterbatch, comprising a device body, an inlet on one side of the top of the device body, an outlet on one side of the bottom of the device body, an auger structure installed inside the device body, one end of the auger structure penetrating one side of the inner wall of the device body and a drive motor fixedly connected to one end of the auger structure, and an anti-blocking structure installed at the other end of the auger structure, the bottom end of the anti-blocking structure corresponding to the outlet position, a first air supply plate installed at the top of the inner wall of the device body, a drying structure installed on the first air supply plate, a first air supply channel provided between the top of the first air supply plate and the top of the inner wall of the device body, the inlet end of the first air supply channel penetrating one side of the inner wall of the device body and a hot air blower fixedly connected to the inlet end of the first air supply channel.

[0004] In the above scheme, hot air is blown out by a hot air blower and sent into the device body through the first air supply channel and the second air supply channel to dry the masterbatch. This has the following disadvantages: the air duct is fixed and the air outlet direction, wind speed or air volume cannot be adjusted according to actual needs (such as material drying amount, material humidity, working environment temperature, etc.), which can easily lead to insufficient or excessive drying in some areas. Utility Model Content

[0005] The purpose of this invention is to provide an angle-adjustable air duct structure to solve the problem that fixed air ducts cannot adjust the air outlet direction, speed, or volume according to actual needs (such as material drying capacity, material humidity, ambient temperature, etc.), which can easily lead to insufficient or excessive drying in certain areas.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an angle-adjustable air duct structure, including a mounting hole, the mounting hole being opened on the top surface of the housing, a guide frame being fixed to the inner wall of the mounting hole, a receiving hole being opened on the front side of the guide frame, an adjusting plate being rotatably arranged on the inner wall of the receiving hole, a first gear being fixed on the connecting columns on both the left and right sides of the adjusting plate, a rotating hole being opened on the left side of the housing, a rotating disk being arranged on the outer left side of the housing, the rotation of the rotating disk being connected in the rotating hole, a second gear being fixed to one end of the connecting rod of the rotating disk, and the second gear meshing with the first gear.

[0007] Preferably, a fan is fixed to the inner wall of the guide frame, and a guide plate is fixed to the inner wall of the guide frame.

[0008] Preferably, the rotating disk has a threaded hole, and a limit bolt is threadedly connected to the inner wall of the threaded hole.

[0009] Preferably, a pointer is fixed on the rotating disk, and a scale line is provided on the left side of the housing, with the pointer corresponding to the scale line.

[0010] Preferably, a workbench is fixed to the bottom surface of the housing, and several receiving slots are opened on the bottom surface of the housing. A limiting plate is provided below the housing, and the limiting plate corresponds to the conveyor belt on the top surface of the workbench. Several mounting posts are fixed to the top surface of the limiting plate, and the mounting posts are inserted into the receiving slots. A spring is connected to the top of the mounting post, and the top of the spring is connected to the inner top surface of the receiving slot.

[0011] Preferably, a plurality of diversion blocks are fixed on the bottom surface of the limiting plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the coordinated action of the adjusting plate, the first gear, the rotating disk, and the second gear, continuous and precise adjustment of the cross-sectional area of ​​the air outlet channel is achieved, ensuring the drying effect of the flame retardant masterbatch. This allows operators to flexibly adjust the air duct according to the drying requirements of the flame retardant masterbatch, effectively preventing uneven drying of the masterbatch and thus improving the adaptability of the air duct to different operating conditions. The curved surface of the guide plate can correct the airflow direction, reduce airflow separation, make the airflow more closely follow the surface of the guide plate, reduce turbulence intensity, and avoid dispersion caused by strong local winds or accumulation caused by weak winds.

[0014] Second, the limiting bolts can be used to limit and fix the rotating disc after rotation, ensuring the stability of the rotating disc after adjustment and effectively preventing the rotating disc from rotating back due to the force of airflow after adjustment. Through the coordinated action of the index and scale lines, the operator can easily and quickly rotate the rotating disc to the required angle, avoiding errors in the air duct caused by angle differences, thereby ensuring the accuracy of the adjustment plate.

[0015] Third, through the coordinated action of the limiting plate, mounting columns, and springs, the height of the limiting plate can be adaptively adjusted. Elastic force feedback dynamically matches the thickness of the flame-retardant masterbatch, ensuring uniform and controllable pressure during the spreading process. This prevents the flame-retardant masterbatch from accumulating during drying and effectively increases the contact area between the hot airflow and the masterbatch. The diverting block, under the action of the limiting plate, can forcibly disperse the flame-retardant masterbatch on the top surface of the conveyor belt from a concentrated state to a uniformly spread state, allowing the hot airflow to circulate evenly between the masterbatch, enabling uniform drying and thus improving the drying efficiency of the flame-retardant masterbatch.

Detailed Implementation

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4As shown, an angle-adjustable air duct structure includes a mounting hole 1, which is opened on the top surface of the housing 2. A guide frame 3 is fixed to the inner wall of the mounting hole 1. A receiving hole 4 is opened on the front side of the guide frame 3. An adjusting plate 5 is rotatably arranged on the inner wall of the receiving hole 4. A first gear 6 is fixed on the connecting columns on the left and right sides of the adjusting plate 5. A rotating hole 7 is opened on the left side of the housing 2. A rotating disk 8 is arranged on the outer left side of the housing 2. The rotating disk 8 is rotatably connected in the rotating hole 7. A second gear 9 is fixed to one end of the connecting rod of the rotating disk 8. The second gear 9 meshes with the first gear 6. A fan 10 is fixed to the inner wall of the guide frame 3. A guide plate 11 is fixed to the inner wall of the guide frame 3.

[0023] In use, when it is necessary to adjust the airflow delivered by the fan 10 in the guide frame 3, the operator can rotate the rotating disk 8 clockwise. During the rotation, the operator can observe the indicated angle of the scale line 15 corresponding to the index 14 to achieve precise operation. The rotating disk 8 will drive the second gear 9 to rotate synchronously through the connecting rod. Under this linkage, the second gear 9 drives the first gear 6 and the adjusting plate 5 to rotate counterclockwise. After the adjusting plate 5 rotates to the preset angle, the limit bolt 13 needs to be tightened to lock and fix the rotating disk 8 to prevent it from rotating in the opposite direction under the subsequent airflow force, thus ensuring the stability of the adjustment state.

[0024] After the above adjustments are completed, the fan 10 is started, and the hot airflow generated by it is transported to the regulating plate 5 through the guide frame 3. Under the guidance and flow restriction of the regulating plate 5, the hot airflow acts on the flame retardant masterbatch on the conveyor belt with the set flow rate and direction, thereby carrying out the drying operation.

[0025] Through the coordinated action of the adjusting plate 5, the first gear 6, the rotating disk 8, and the second gear 9, continuous and precise adjustment of the cross-sectional area of ​​the air outlet channel is achieved, ensuring the drying effect of the flame retardant masterbatch. This allows operators to flexibly adjust the air duct according to the drying requirements of the flame retardant masterbatch, effectively preventing uneven drying of the masterbatch and thus improving the adaptability of the air duct. The curved surface of the guide plate 11 can correct the airflow direction, reduce airflow separation, make the airflow more closely follow the surface of the guide plate 11, reduce turbulence intensity, and avoid dispersion caused by strong local winds or accumulation caused by weak winds.

[0026] like Figures 1-4 As shown, a threaded hole 12 is provided on the rotating disk 8, and a limit bolt 13 is threadedly connected to the inner wall of the threaded hole 12. An index 14 is fixed on the rotating disk 8, and a scale line 15 is provided on the left side of the housing 2. The index 14 corresponds to the scale line 15.

[0027] During use, the limiting bolt 13 can limit and fix the rotating disk 8 after rotation, ensuring the stability of the rotating disk 8 after adjustment and effectively preventing the rotating disk 8 from rotating back due to the force of airflow after adjustment. Through the coordinated action of the index 14 and the scale line 15, the operator can easily and quickly rotate the rotating disk 8 to the required angle, avoiding errors in the air duct caused by angle differences, thereby ensuring the accuracy of the adjustment plate 5.

[0028] like Figure 1 and Figure 2 As shown, a workbench 16 is fixed on the bottom surface of the housing 2, and several receiving slots 17 are opened on the bottom surface of the housing 2. A limiting plate 18 is provided below the housing 2. The limiting plate 18 corresponds to the conveyor belt on the top surface of the workbench 16. Several mounting posts 19 are fixed on the top surface of the limiting plate 18. The mounting posts 19 are inserted into the receiving slots 17. A spring 20 is connected to the top of the mounting post 19. The top of the spring 20 is connected to the inner top surface of the receiving slot 17. Several diverting blocks 21 are fixed on the bottom surface of the limiting plate 18.

[0029] In use, the height of the limiting plate 18 can be adaptively adjusted through the coordinated action of the limiting plate 18, the mounting column 19, and the spring 20. The thickness of the flame-retardant masterbatch is dynamically matched through elastic force feedback, ensuring uniform and controllable pressure during the spreading process. This prevents the flame-retardant masterbatch from accumulating during drying and effectively increases the contact area between the hot airflow and the flame-retardant masterbatch. The diverting block 21, under the action of the limiting plate 18, can forcibly disperse the flame-retardant masterbatch on the top surface of the conveyor belt from a concentrated state to a uniformly spread state, allowing the hot airflow to circulate evenly between the flame-retardant masterbatch, enabling uniform drying and thus improving the drying efficiency of the flame-retardant masterbatch.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
