[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-Figure 3 The utility model provides a high-temperature dust blowing device for a roller kiln, comprising a transmission roller 1, which is a prior art. The transmission roller 1 is used to allow the object to be heated to enter the interior of a working box 2 from one end and be output from the other end. The surface of the transmission roller 1 is fixedly connected to the working box 2, and both sides of the outer wall of the working box 2 are fixedly connected to a mechanical box 3. The surface of the mechanical box 3 is fixedly connected to a fan 4, and the surface of the fan 4 is fixedly connected to a hose 5. A rotor is arranged inside the fan 4, and wind is generated by the rotation of the rotor to blow air outward through the hose 5. The hose 5 is made of high-temperature resistant material, has high high-temperature resistance and also has a soft and retractable effect. The hose 5 penetrates and is fixedly connected to the inner wall of the gear 13, and the hose 5 penetrates and is fixedly connected to the inner wall of the sliding disk 12.
[0026] See also Figure 2-Figure 4 The end of the hose 5 away from the fan 4 is fixedly connected to the blowing port 14. When the fan 4 blows air outward through the hose 5, it will cooperate with the blowing port 14 to discharge the wind outward from the blowing port 14. The inner wall of the working box 2 is provided with multiple sets of racks 11. The shape of the racks 11 is adapted to the shape of the gear 13. The top of the outer wall of the working box 2 is fixedly connected to a motor 6. The output shaft of the motor 6 is fixedly connected to a turntable 7. The turntable 7 is rotatably connected to the outer wall of the top of the working box 2. The surface of the turntable 7 is fixedly connected to a fixed column 8. The outer wall of the fixed column 8 is rotatably connected to a connecting rod 9. When the turntable 7 rotates, the fixed column 8 on its surface will drive the connecting rod 9 to rotate synchronously, thereby pulling the sliding column 10 to move on the inner wall of the sliding disk 12.
[0027] See also Figure 3The end of the connecting rod 9 away from the fixed column 8 is rotatably connected to the sliding column 10, and the inner wall of the working box 2 is rotatably connected to the sliding disk 12. The surface of the sliding disk 12 is provided with an annular guide groove, and the bottom end of the outer wall of the sliding column 10 is slidably connected to the inner wall of the annular guide groove. When the sliding column 10 moves following the sliding of the connecting rod 9, it will push the sliding column 10 to move in the annular guide groove of the sliding disk 12, thereby pushing the sliding disk 12 to reciprocate on the inner wall of the working box 2. The top of the outer wall of the sliding disk 12 is fixedly connected with a gear 13, and the gear 13 is meshed with the rack 11. The meshing between the two allows the sliding disk 12 to rotate while reciprocating. The bottom end of the outer wall of the sliding disk 12 is fixedly connected with an air outlet 14.
[0028] See also Figure 5 The inner wall of the working box 2 is clamped with a moving column 15 through a limiting mechanism. The moving column 15 penetrates and is slidably connected to the inner wall of the working box 2. By moving the position of the moving column 15 on the inner wall of the working box 2, the length can be adjusted according to the size of different objects. The limiting mechanism includes a wedge 18, and the wedge 18 is elastically connected to the inner wall of the working box 2 through a limiting spring 17. One end of the limiting spring 17 is fixedly connected to the outer side wall of the wedge 18, and the other end of the limiting spring 17 is fixedly connected to the inner wall of the working box 2. When the moving column 15 is pushed to move on the inner wall of the working box 2, the card slot at its current position will squeeze the inclined surface of the wedge 18, thereby moving the wedge 18 on the inner wall of the working box 2 until the next set of card slots When it is in the position, it will be elastically acted upon by the limit spring 17, restoring it to its initial position, so as to engage with the slot at the current position. The wedge block 18 is slidably connected to the inner wall of the working box 2. The side wall of the movable column 15 is provided with a plurality of slots, and the wedge block 18 is engaged with the slots. The engagement between the two fixes the position of the movable column 15 after adjustment according to the size of the object, so as to avoid separation during use. The inner side wall of the movable column 15 is rotatably connected with the guide wheel 16. By setting the guide wheel 16, when the object moves along the surface of the transmission roller 1, its outer wall will contact with the outer wall of the guide wheel 16, so that the angle of the object on the transmission roller 1 is moved by the rotation of the guide wheel 16.
[0029] Working principle: when placing an object on the surface of the transmission roller 1 and transporting it to the inside of the working box 2 for high-temperature heating, the fan 4 is started to blow air, and air is blown outward from the blowing port 14 through the hose 5. At this time, the motor 6 is started again, and the output shaft of the motor 6 will drive the turntable 7 to rotate. When the turntable 7 rotates, the fixed column 8 on its surface will drive the connecting rod 9 to move synchronously. When the connecting rod 9 rotates following the fixed column 8, it will drive the back and forth reciprocation so that the sliding column 10 at the other end will slide on the inner wall of the sliding disk 12, thereby pushing the sliding disk 12 to reciprocate up and down on the inner wall of the working box 2 to blow dust off the surface of the object. When the sliding disk 12 reciprocates up and down, the gear 13 on its surface will mesh with the rack 11, so that the sliding disk 12 can rotate while reciprocating, so that the dust blowing effect is better.
[0030] At the same time, when the object enters the interior of the working box 2, its placement position is mostly fixed. At this time, by pressing the movable column 15 to move inside the working box 2, the guide wheel 16 can be adjusted according to the size of different objects. When the movable column 15 is pushed to move on the inner wall of the working box 2, the slot at its current position will squeeze the inclined surface of the wedge block 18, thereby moving the wedge block 18 on the inner wall of the working box 2 until the next set of slots. It will be elastically acted upon by the limit spring 17 to restore it to its initial position to engage with the slot at its current position. At this time, when the object contacts the outer wall of the guide wheel 16, it will squeeze the guide wheel 16 and be rotated by the wheel body of the guide wheel 16 to change the angle of the object, thereby blowing dust at the other side of the object through the next set of air outlets 14.
[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
