[0036] As attached Figure 1 -Attached Figure 5 As shown, the utility model provides a roller kiln feeding and discharging device, comprising a conveying bin 1, a feeding and discharging assembly 2 and a feeding and discharging conveyor 3;

[0037] The conveying bin 1 can be directly the kiln body of the roller kiln, or it can be a feeding transition bin connected to the head end of the roller kiln for feeding, or it can be a discharging transition bin connected to the end of the roller kiln for discharging;

[0038] The inlet and outlet assembly 2 is used to transport the material 5 in the conveying bin 1 to the inlet and outlet conveyor 3. At this time, the inlet and outlet assembly 2 is used as a discharging assembly. The inlet and outlet assembly 2 can also be used to transport the material 5 on the inlet and outlet conveyor 3 to the conveying bin 1. At this time, the inlet and outlet assembly 2 is used as a feeding assembly.

[0039] Similarly, the in-and-out material conveyor 3 is used to convey the material conveyed from the in-and-out material assembly 2 to the next workstation. At this time, the in-and-out material conveyor 3 is used as a discharge conveyor. The in-and-out material conveyor 3 can also be used to input material 5 and convey the material 5 to the in-and-out material assembly 2. Finally, the material 5 is conveyed from the in-and-out material assembly 2 to the conveying bin 1. At this time, the in-and-out material conveyor 3 is used as a feed conveyor.

[0040] The conveying bin 1 is provided with a bin door 11 for opening and closing the conveying bin 1 to prevent the conveying bin 1 from being opened when there is no need to discharge materials, thereby preventing the temperature in the roller kiln from being lost or air from entering the roller kiln. The feeding and discharging assembly 2 includes a fork mechanism 21 and a transition conveyor 22. During the feeding and discharging steps of the roller kiln, the bin door 11 of the utility model is opened for a short time, which can reduce heat loss and thus reduce energy consumption.

[0041] The fork mechanism 21 includes a linear drive component 211 and two fork arms 212 arranged on the output end of the linear drive component 211. The linear drive component 211 drives the fork arms 212 to extend into the conveying bin 1 through the bin door 11 to receive or unload the material 5. Preferably, the linear drive component 211 drives the fork arms 212 to move horizontally, and then extend into the conveying bin 1 through the bin door 11 to receive or unload the material 5, so as to ensure the stability of receiving or unloading the material.

[0042] The transition conveyor 22 includes a lifting mechanism Ⅰ221 and a roller conveyor Ⅰ222 arranged on the conveying end of the lifting mechanism Ⅰ221. The roller conveyor Ⅰ222 is located between the two fork arms 212 to ensure that the roller conveyor Ⅰ222 and the two fork arms 212 do not interfere with each other during their movement. During the discharging process of the roller kiln, after the fork arm 212 receives the material 5 from the conveying bin 1 and resets, the lifting mechanism Ⅰ221 drives the roller conveyor Ⅰ222 to rise to receive the material 5 and convey the material to the in-and-out conveyor 3; during the feeding process of the roller kiln, after the material 5 is conveyed from the in-and-out conveyor 3 to the roller conveyor Ⅰ222, the lifting mechanism Ⅰ221 drives the roller conveyor Ⅰ222 to descend, so that the material 5 is carried by the fork arm 212, and the fork arm 212 is driven by the linear drive component 211 to deliver the material 5 into the conveying bin 1.

[0043] The roller kiln feeding and discharging device provided by the utility model can be used for feeding at the feeding end of the roller kiln and for discharging at the discharging end of the roller kiln, which can reduce the research and development cost of the feeding and discharging mechanism of the roller kiln. At the same time, the feeding and discharging of the roller kiln can be directly switched by switching the conveying direction of the roller kiln and the movement sequence of the roller kiln feeding and discharging device, which greatly improves the adaptability of the device. Specifically, when discharging the material 5 in the roller kiln, the fork arm 212 receives the material 5 inside the conveying bin 1, and the fork arm 212 resets after receiving the material 5, and then the lifting mechanism I221 drives the roller conveyor I222 to rise to receive the material 5, and then the roller conveyor I222 transports the material to the feeding and discharging conveyor 3. When the material 5 is fed into the roller kiln, the material is transported from the inlet and outlet conveyor 3 to the roller conveyor I222, and then the lifting mechanism I221 drives the roller conveyor I222 to descend so that the two fork arms 212 can receive the material 5, and then the linear drive assembly 211 drives the two fork arms 212 to transport the material 5 to the conveying bin 1 for unloading. The positional relationship between the fork arms 212 and the transition conveyor 22, that is, the lifting mechanism I221 and the roller conveyor I222 are arranged between the two fork arms 212, can reasonably utilize the space outside the door 11 of the conveying bin 1, can realize that the material 5 is taken out from the conveying bin 1 by the fork arm 212, and then the roller conveyor I222 receives the material 5 from the fork arm 212 and transports it, and can also realize that the roller conveyor I222 first carries the material, and then the roller conveyor I222 descends to transfer the material 5 to be carried by the two fork arms 212. On the basis of ensuring the compact structure, the material 5 can be taken out from the conveying bin 1 and conveyed to the conveying bin 1 stably and reliably, the material 5 can be unloaded from the fork arm 212 and the material 5 can be transferred to the fork arm 212 efficiently and stably, and at the same time, there will be no problems such as difficulty in reversing and difficulty in adjusting the discharge height caused by the conventional discharge method of directly connecting the conveying rollers with the conveying rollers (the discharge method of the conveying roller connecting the conveying roller requires one of the conveying rollers to be arranged at an angle if the discharge height needs to be adjusted, and the weight of the material sintered in the roller kiln is very heavy, and inclined transportation will pose a safety hazard).

[0044] In one embodiment, when the lifting mechanism I 221 rises to allow the roller conveyor I 222 to receive the material 5, the roller conveyor I 222 and the in-and-out conveyor 3 are at the same height, and the two fork arms 212 are lower than the roller conveyor I 222 and the in-and-out conveyor 3, and the material 5 passes through the roller conveyor I 222 and the in-and-out conveyor 3. In this embodiment, when the lifting mechanism I 221 rises to allow the roller conveyor I 222 to receive the material 5, the material 5 is directly lifted from the fork arm 212, so that the material 5 is completely separated from the fork arm 212. At this time, the roller body on the roller conveyor I 222 rotates to move the material 5 toward the in-and-out conveyor 3, and the conveying efficiency can be guaranteed at this time.

[0045] In another embodiment, since the current roller kiln discharge is generally a rolling conveying scheme (i.e., the materials are transported by rotating the roller body), the materials in the roller kiln are large in volume and heavy in weight. Considering the deadweight and inertia of the materials, the roller body cannot run too fast, resulting in a long discharge time. Therefore, in order to improve the conveying efficiency, when the lifting mechanism I221 rises to make the roller conveyor I222 take over the material 5, the roller conveyor I222, the fork arm 212 and the in-and-out conveyor 3 are at the same height. During the roller kiln discharge process, the material 5 passes through the roller conveyor I222, the fork arm 212 located between the roller conveyor I222 and the in-and-out conveyor 3, and the in-and-out conveyor 3 in sequence. During the roller kiln feeding process, the material 5 passes through the in-and-out conveyor 3, the fork arm 212 located between the roller conveyor I222 and the in-and-out conveyor 3, and the roller conveyor I222 in sequence. In this embodiment, when the lifting mechanism Ⅰ221 rises to allow the roller conveyor Ⅰ222 to receive the material 5, the material 5 is still in contact with the fork arm 212; at this time, the roller body on the roller conveyor Ⅰ222 rotates to move the material 5 toward the in-feed and out-feed conveyor 3, and during the movement, the material 5 always rubs against the fork arm 212 between the roller conveyor Ⅰ222 and the in-feed and out-feed conveyor 3 to form frictional sliding to provide a certain friction force. Therefore, it is not necessary to consider the weight and inertia of the material, and the conveying speed of the roller conveyor Ⅰ222 and the in-feed and out-feed conveyor 3 is guaranteed. The problem of extending the braking distance of the material 5 due to inertia will not occur, and the conveying stability of the roller body is guaranteed while ensuring efficiency. This embodiment is suitable for the case where the weight of the material 5 is heavy. Preferably, in this embodiment, the fork arm 212 is made of graphite.

[0046] In one embodiment, a limit plate 2121 is provided on the fork arm 212, and the limit plate 2121 is vertically arranged at the downstream position of the fork arm 212, and the limit plate 2121 is flush with the end of the roller bar of the roller conveyor I222. In this embodiment, when the fork arm 212 is extended into the conveying bin 1 to take materials, when the material 5 abuts against the limit plate 2121, it means that the docking of the material 5 and the fork arm 212 is completed. At this time, after the linear drive member I2113 drives the fork arm 212 to reset, the lifting mechanism I221 directly lifts the roller conveyor I222, so that the roller conveyor I222 can receive the material 5. At this time, the material 5 is directly located in the middle of the roller body on the roller conveyor I222, and there is no need to complete the positioning of the material 5 and the roller conveyor I222 separately, thereby improving the discharging efficiency and simplifying the positioning difficulty. The fork arm 212 can also limit and position the material 5 when extending into the conveying bin 1 to feed materials, which will not be repeated here.

[0047] In one embodiment, the feed and discharge conveyor 3 includes a roller conveyor II31, which is supported by a fixed bracket II32 so that the roller conveyor II31 is at the same height as the roller conveyor I222. The roller conveyor II31 and the roller conveyor I222 are located on the same straight line, that is, the material 5 is conveyed in a straight line, wherein the roller bodies of the roller conveyor I222 and the roller conveyor II31 have rotational power and can drive the material 5 to move, that is, an electric roller can be used to cooperate with a chain to drive other rollers for transmission. In addition, there is a gap between the roller conveyor II31 and the roller conveyor I222, and the fork arm 212 located between the roller conveyor I222 and the feed and discharge conveyor 3 is in the gap to provide an installation space for the fork arm 212.

[0048] In one embodiment, the material inlet and outlet assembly 2 further includes a fixing bracket I 23;

[0049] The linear drive assembly 211 includes a guide rail assembly 2111 arranged on a fixed bracket Ⅰ23 and facing the warehouse door 11, a sliding frame 2112 slidably arranged on the guide rail assembly 2111, and a linear drive component Ⅰ2113 driving the sliding frame 2112 to move along the guide rail assembly 2111. The two fork arms 212 are fixedly arranged on the sliding frame 2112. Such an arrangement can ensure the movement stability of the fork arms 212 and the carrying capacity of the fork arms 212. The linear drive component Ⅰ2113 can adopt similar drive components such as cylinders, oil cylinders or electric cylinders.

[0050] In one embodiment, a conveying roller assembly 12 and a lifting mechanism II 13 are provided in the conveying bin 1. The lifting mechanism II 13 is provided at the end of the conveying roller assembly 12 and is used to lift or lower the material 5 conveyed to the bin door 11. When the roller kiln is feeding, the lifting mechanism II 13 is used to lower the material 5 conveyed to the bin door 11 so that the material 5 enters the conveying roller assembly 12. When the roller kiln is discharging, the lifting mechanism II 13 is used to lift the material 5 conveyed to the bin door 11 so that the material 5 leaves the conveying roller assembly 12. Part 12, and is taken up by the fork material mechanism 21. Specifically, the output end of the lifting mechanism II13 lifts the material 5 through the gap between the roller bodies of the conveying roller assembly 12, and the output end of the lifting mechanism II13 is staggered with the two fork arms 212. In this embodiment, when the roller kiln is feeding, the fork arm 212 carries the material 5 into the bin door 11, and then the lifting mechanism II13 lifts the material 5 from the fork arm 212, and the fork arm 212 is reset. Finally, the lifting mechanism II13 is reset to place the material 5 on the conveying roller assembly 12. When the roller kiln is discharging, before the fork arm 212 carries the material 5, the lifting mechanism II13 lifts the material 5 to facilitate the fork arm 212 to insert into the bottom of the material 5 for acceptance.

[0051] In one embodiment, the warehouse door 11 includes a door panel 111 longitudinally slidably arranged on the conveying warehouse 1, and a linear driving member Ⅱ112 arranged on the outer wall of the conveying warehouse 1 for driving the door panel 111 to slide. With this arrangement, the warehouse door 11 can be opened and closed in the longitudinal direction without affecting the space in front of the warehouse door 11.

[0052] In one of the embodiments, an air curtain assembly 4 is provided in the conveying bin 1; the distance from the air curtain assembly 4 to the bin door 11 is greater than the size of the material 5, that is, the material 5 can be located between the air curtain assembly 4 and the bin door 11. At this time, after the material 5 has completely passed through the air curtain assembly 4 and is located before the bin door 11, the air curtain assembly 4 can be opened first to form an air curtain, and then the bin door 11 can be opened. By providing the air curtain assembly 4, the air curtain assembly 4 can be opened before or during the opening of the bin door 11, and the protective gas is released toward the bin door 11 through the air curtain assembly 4, which effectively reduces the external air from entering the conveying bin 1 and the roller kiln through the bin door 11, and reduces the influence of the opening of the bin door 11 on the sintering atmosphere inside the roller kiln. The air curtain assembly 4 is suitable for the feeding step of the roller kiln, and is also used in the discharging step of the roller kiln.

[0053] In one embodiment, the air curtain assembly 4 includes an air curtain main pipe 41, a connecting pipe 42 and a nozzle 44;

[0054] The air curtain main pipe 41 is arranged on the top plate inside the conveying bin 1, and the length of the air curtain main pipe 41 is equal to the width inside the conveying bin 1, so that the formed air curtain can cover the cross-sectional area of ​​the entire conveying bin 1, thereby improving the gas isolation effect;

[0055] One end of the connecting pipe 42 is connected to the air curtain main pipe 41, and the other end passes through the outside of the conveying bin 1, and is used to connect to the protective gas tank, so as to facilitate the connection with the gas source. In addition, the gas source preferably uses protective gas to ensure the sintering effect;

[0056] A plurality of nozzles 44 are arranged at intervals along the length direction at the lower end of the air curtain main pipe 41, thereby ensuring high stability of the air curtain.

[0057] In one embodiment, a solenoid valve 43 is provided on the connecting pipe 42 , so as to conveniently control the opening and closing of the air curtain assembly 4 .

[0059] The conveying bin material position sensor is arranged on the conveying bin 1, and is used to detect the position of the material 5 in the conveying bin 1. The conveying bin material position sensor preferably adopts a through-beam sensor. When the through-beam sensor detects that the material 5 moves between the air curtain assembly 4 and the bin door 11, the air curtain assembly 4 and the bin door 11 are opened, and the material 5 is discharged, and the air is reduced from entering the conveying bin 1 during the discharge of the material 5.

[0060] The fork arm material detection sensor is arranged on the fork arm 212, preferably on the limit plate 2121 of the fork arm 212, and is used to detect whether the fork arm 212 carries the material 5 to avoid an empty fork;

[0061] The material position sensor of the inlet and outlet assembly is arranged on the transition conveyor 22, and is used to detect the position of the material 5 on the transition conveyor 22, so as to be fed back to the PLC controller as a basis for adjusting the conveying speed of the transition conveyor 22;

[0062] The material distance sensor of the inlet and outlet conveyor is set on the inlet and outlet conveyor 3, and is used to detect the distance between the material 5 and the inlet and outlet conveyor 3, so as to control the conveying speed of the inlet and outlet conveyor 3, so as to achieve a speed close to zero when contacting the material 5, and synchronize with the conveying speed of the transition conveyor 22 and accelerate evenly after receiving the material 5.

[0063] The utility model also provides a roller kiln feeding and discharging method, using the above roller kiln feeding and discharging device, including a roller kiln feeding mode or a roller kiln discharging mode;

[0071] Preferably, before step S14, that is, before the door 11 is opened, the air curtain assembly 4 is controlled to be opened, and the plurality of nozzles 44 form a protective gas curtain at the downstream end of the conveying bin 1. In this way, when the door 11 is opened, the heat loss in the conveying bin 1 can be prevented, and the external air can be prevented from entering the conveying bin 1, until the door 11 is closed in step S15, and then the air curtain assembly 4 is controlled to be closed.
