[0011] The dust suction device of the sintering production line according to the embodiment of the present utility model, a pressure sensor is arranged inside the sliding telescopic column, and the upper end of the pressure sensor is fixedly connected to the sliding end of the sliding telescopic column through a spring.
[0012] The dust suction device of the sintering production line according to the embodiment of the present utility model, one side of the electromagnet is fixedly connected to the inner wall of the dust suction box, and the electromagnet is used for magnetically attracting the sliding column and the sliding telescopic column.

[0032] The dust suction device for a sintering production line according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.
[0033] Refer to Figures 1 to 5 , the present utility model aims to provide an embodiment of a dust suction device for a sintering production line. The dust suction device for the sintering production line in this embodiment mainly includes a sintering furnace 1, a conveying device 2, and a dust suction box 3. The sintering furnace 1 is used for sintering articles, the conveying device 2 is used for transporting processed products, and the dust suction box 3 is used for adsorbing powders of the products to be processed.
[0034] In some specific embodiments of the present utility model, the products to be sintered can be transported into the sintering furnace 1 through an external driving method, and then sintered.
[0035] In some specific embodiments of the present utility model, a conveying device 2 can be arranged outside the sintering furnace 1, and the materials to be sintered can be conveyed into the sintering furnace 1 through the conveying device 2.
[0036] In some specific embodiments of the present utility model, a dust suction box 3 can be arranged on the upper surface of the conveying device 2. Through the dust suction box 3, the products sintered inside the sintering furnace 1 can be subjected to dust suction treatment, thereby avoiding bumps on the product surface to the greatest extent.
[0037] In some specific embodiments of the present utility model, the products to be sintered can be placed on the conveying device 2, and at the same time, the sieve frame 7 can be used to initially suspend the products. Furthermore, in cooperation with the dust suction work of the dust suction box 3, the lower end of the dust suction box 3 is connected to the non-moving parts on both sides of the conveying device 2, thereby avoiding the influence on the dust suction box 3 when the conveying device 2 conveys the products to be sintered.
[0038] Reference Figure 3 , in some specific embodiments of the present utility model, the dust suction box 3 can include a dust suction fan 4, a diversion cover 13, and a plurality of guiding bases 14. The dust suction fan 4 is used for dust suction of the products, the diversion cover 13 is used for diversion of product adsorption, and the guiding bases 14 are used for vibration guiding of the products. A sliding column 17 and a sliding telescopic column 18 are slidably arranged in the guiding bases 14. Thus, the dust suction box 3 can use the dust suction fan 4 to perform dust suction treatment on the products to be sintered, and at the same time, the dust suction fan 4 can adsorb the powder to the greatest extent through the diversion cover 13.
[0039] In some specific embodiments of the present utility model, the dust suction fan 4 can be arranged at the upper end of the dust suction box 3, and the adsorption port of the dust suction fan 4 extends into the interior of the dust suction box 3. Thus, the dust suction box 3 can use the dust suction fan 4 to adsorb the powder.
[0040] In some specific embodiments of the present utility model, by installing the diversion cover 13 at the opening of the dust suction fan 4, the diversion cover 13 can guide the adsorbed powder, and as much as possible, avoid the phenomenon of powder disorder inside the dust suction box 3 caused by the action of the dust suction fan 4.
[0041] In some specific embodiments of the present utility model, the shape of the diversion cover 13 can be set as a trapezoid, and the end with a larger opening faces the dust suction box 3, thereby covering the sieve frame 7.
[0042] In some specific embodiments of the present utility model, vibration springs 15 are fixedly arranged at the inner bottom of the guiding bases 14. The vibration springs 15 are used for the falling and rebounding of the products. The sliding columns 17 and the sliding telescopic columns 18 are respectively fixedly connected with connecting sliding rods 16 through the driving rotating shafts 19 and rotating shafts. Electromagnets 20 are arranged above each guiding base 14.
[0043] In some specific embodiments of the present utility model, by arranging electromagnets 20 directly above each guiding base 14, when the electromagnets 20 are turned on, the sliding columns 17 and the sliding telescopic columns 18 can be adsorbed, so that the sliding columns 17 and the sliding telescopic columns 18 can move upward. When the electromagnets 20 are turned off, the sliding columns 17 and the sliding telescopic columns 18 drop due to gravity and contact the vibration springs 15. Then, the vibration springs 15 rebound the sliding columns 17 and the sliding telescopic columns 18 according to their own characteristics.
[0044] In some specific embodiments of the present utility model, connecting sliding rods 16 can be rotatably arranged at one ends of the sliding columns 17 and the sliding telescopic columns 18, and the lengths of the sliding columns 17 and the sliding telescopic columns 18 are different, with the sliding telescopic column 18 being longer. Thus, the connecting sliding rods 16 on both sides are in a shape of an eight. Then, when the sieve frame 7 moves into the dust collection box 3, it can first contact the part with a larger opening, and then, by means of extrusion and rotation, keep the sliding columns 17 and the sliding telescopic columns 18 on both sides level. Further, the sliding connection between the sieve frame 7 and the connecting sliding rods 16 is completed.
[0045] In summary, first, in this embodiment, by setting the conveying device 2, the conveying device 2 can convey the products to be sintered. When the conveying device 2 passes under the dust collection box 3, the conveying device 2 stops. Then, the dust collection box 3 sucks the powder of the products. After the dust collection box 3 finishes working, the conveying device 2 continues to convey the products. Thus, the dust collection box 3 can suck the next product that needs to remove the powder.
[0046] Secondly, in this embodiment, by arranging the guiding bases 14 inside the dust collection box 3, and the sliding columns 17 and the sliding telescopic columns 18 slidably arranged inside the guiding bases 14, they can be lifted by the action of the electromagnets 20 being turned on. When the electromagnets 20 are no longer activated, the sliding columns 17 and the sliding telescopic columns 18 are separated from the electromagnets 20, and then fall inside the guiding bases 14. At the same time, the vibration springs 15 arranged inside the guiding bases 14 can react on the sliding columns 17 and the sliding telescopic columns 18 when they fall. Thus, the sliding columns 17 and the sliding telescopic columns 18 can move vertically repeatedly inside the guiding bases 14. Then, the sieve frame 7 connected by the sliding columns 17 and the sliding telescopic columns 18 can be vibrated, and the dust collection effect can be improved.
[0047] Furthermore, the length of the sliding telescopic column 18 should be greater than that of the sliding column 17. Thus, the connecting slide rods 16 on both sides are in a V-shape. Therefore, after the sieve frame 7 moves into the interior of the dust suction box 3, the sliding telescopic column 18 is retracted by extrusion. Furthermore, the connecting slide rod 16 is leveled and slidably connected to the sieve frame 7. At the same time, after the connecting slide rod 16 is leveled, it can have a small clamping force. Subsequently, the connection between the connecting slide rod 16 and the sieve frame 7 can be strengthened slightly.
[0048] In some specific embodiments of the present utility model, the number of the guiding bases 14 can be four, and every two guiding bases 14 form a group, and the positions of each group of guiding bases 14 correspond to each other.
[0049] It is easy to understand that in this embodiment, by setting the number of the guiding bases 14 to four and the positions of each group of guiding bases 14 corresponding to each other, when the sliding column 17 and the sliding telescopic column 18 are acted on by the electromagnet 20, the lifting of the connecting slide rod 16 can be stable.
[0050] In some specific embodiments of the present utility model, one ends of both the sliding column 17 and the sliding telescopic column 18 are rotatably connected to the driving rotating shaft 19 and the rotating shaft through the connecting disks. A driving motor 22 is arranged above the driving rotating shaft 19, and the driving motor 22 is used for driving the rotation of the driving rotating shaft 19.
[0051] It is easy to understand that in this embodiment, by arranging the connecting disks at one ends of the sliding column 17 and the sliding telescopic column 18, the driving rotating shaft 19 and the rotating shaft can be rotatably connected to the sliding column 17 and the sliding telescopic column 18. At the same time, with the arrangement of the driving motor 22, the driving motor 22 can be used to make the driving rotating shaft 19 act actively. Furthermore, the driving rotating shaft 19 can swing the connecting slide rod 16, so that the sliding telescopic column 18 connected to the other end of the connecting slide rod 16 is actively retracted.
[0052] Reference Figure 5 In some specific embodiments of the present utility model, a pressure sensor 21 is arranged inside the sliding telescopic column 18, and the upper end of the pressure sensor 21 is fixedly connected to the sliding end of the sliding telescopic column 18 through a spring.
[0053] It is easily understandable that in this embodiment, by arranging a pressure sensor 21 inside the sliding telescopic column 18, when the sliding end of the sliding telescopic column 18 is retracted, the pressure sensor 21 can be pressed by compressing the spring. Therefore, an electrical signal can be sent to the drive motor 22 through the pressure sensor 21, and then the drive motor 22 can drive the driving rotating shaft 19 to rotate slightly, thereby assisting the connecting sliding rod 16 to be leveled. Moreover, the electromagnet 20 also starts to work under the signal of the pressure sensor 21, and the start of the electromagnet 20 is intermittent at multiple points for the dust collection box 3. Therefore, the sliding column 17 and the sliding telescopic column 18 are intermittently adsorbed.
[0054] Furthermore, the drive motor 22 can also send a signal to the dust suction fan 4, and then the dust suction fan 4 can be started to suck the products below it.
[0055] In some specific embodiments of the present utility model, one side of the electromagnet 20 can be fixedly connected to the inner wall of the dust collection box 3, and the electromagnet 20 is used for magnetically attracting the sliding column 17 and the sliding telescopic column 18.
[0056] It is easily understandable that in this embodiment, by fixedly connecting the electromagnet 20 to the inner wall of the dust collection box 3, the position of the electromagnet 20 can be limited, preventing the electromagnet 20 from moving and causing the inability to attract the sliding column 17 and the sliding telescopic column 18.
[0057] In some specific embodiments of the present utility model, a sieve frame 7 can be arranged on the upper surface of the conveying device 2, and sliding grooves 8 are opened on both corresponding sides of the sieve frame 7. The sliding grooves 8 are used for the sliding connection between the sieve frame 7 and the connecting sliding rod 16.
[0058] It is easily understandable that in this embodiment, by arranging the sieve frame 7 on the upper surface of the conveying device 2, and the sliding grooves 8 opened on both sides of the sieve frame 7 can be slidably connected to the connecting sliding rod 16. Furthermore, the sieve frame 7 can move through the conveying device 2, and when the sieve frame 7 moves below the dust collection box 3, it can slide with the connecting sliding rod 16.
[0059] In some specific embodiments of the present utility model, one side of the dust suction fan 4 can be connected to a dust collection bucket 10 through a dust collection pipe 9, and the dust collection bucket 10 is used for the recovery of powder.
[0060] It is easily understandable that in this embodiment, by arranging the dust collection pipe 9, the powder sucked by the dust suction fan 4 can move through the dust collection pipe 9 into the interior of the dust collection bucket 10, and then the dust collection bucket 10 collects the dust uniformly.
[0061] Reference Figure 2, in some specific embodiments of the present utility model, the lower end of the conveying device 2 can be fixedly connected with a driving motor 5 through a bracket. The output end of the driving motor 5 is fixedly connected with a driving wheel 11. The driving wheel 11 is belt-driven by a transmission belt 12 to be connected with a driven wheel, and the driven wheel is used for driving the conveying device 2.
[0062] It is easy to understand that in this embodiment, by setting the bracket, the position of the conveying device 2 can be limited. At the same time, the driving motor 5 can drive the driven wheel through the driving wheel 11 and the transmission belt 12. In this way, the normal operation of the conveying device 2 can be ensured.
[0063] In the description of this specification, the description with reference to terms such as "one embodiment, some embodiments, illustrative embodiments, examples, specific examples or some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
[0064] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which it pertains, various changes can also be made without departing from the gist of the present utility model.
