Currently, photoelectric tubes or photoelectric switches are installed in the elevator and storage bin to detect whether there is material, but the photoelectric tubes and photoelectric switches are easily blocked by signals, resulting in inaccurate detection data and failure to ensure a stable supply of materials.

[0044] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are 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.

[0045] Combine the following Figure 1 to Figure 2 , the tobacco feeding device with the function of preventing feed breakage provided by the embodiment of the utility model is described in detail through specific embodiments and application scenarios.

[0046] In some embodiments, Figure 1 and Figure 2 As shown, this embodiment provides a tobacco feeding device with a function of preventing material breakage, including: a storage bin 1, an elevator 2, a distance measuring component 3 and an air blowing component 4.

[0047] One end of the storage bin 1 is connected to the front-end equipment, the other end of the storage bin 1 is connected to one end of the elevator 2, and the other end of the elevator 2 is connected to the back-end equipment.

[0048] The distance measuring component 3 is movably arranged on the lifting machine 2 , and the air blowing component 4 is arranged opposite to the distance measuring component 3 .

[0049] The distance measuring component 3 moves between the first position P1 and the second position P2; the area between the first position P1 and the second position P2 is the area where the hoist 2 is prone to material breaking.

[0050] The distance measuring component 3 is used to detect the thickness of the material on the lifting belt of the elevator 2, and the air blowing component 4 is used to blow air to the distance measuring component 3.

[0051] It is understandable that in the tobacco feeding device, the storage bin 1 is used to buffer materials such as tobacco leaves and tobacco shreds delivered from the previous process. A certain amount of materials are stored in the storage and transported to the elevator 2 through the bottom belt 11. The lifting belt of the elevator 2 further transports the materials to the back-end equipment.

[0052] The distance measuring component 3 detects the distance between the outer surface of the material at a certain position and the distance measuring component 3, and based on the constant distance between the distance measuring component 3 and the lifting belt of the elevator 2, the thickness of the material in the elevator 2 is detected. The distance measuring component 3 moves between the areas of the elevator 2 where the material is prone to breakage to detect the thickness of the material at different positions in the area, and then detect the uniformity of the thickness of the material in the area.

[0053] Specifically, the distance measuring component 3 can be a photoelectric distance measuring component or an acoustic wave distance measuring component.

[0054] When there are a lot of adhered tobacco leaves or dust around the distance measuring component 3, it is easy to block the distance measuring component 3, resulting in inaccurate results of detecting the material thickness. At this time, the blowing component 4 can be started to blow air to the distance measuring component 3 to ensure that the surrounding environment of the distance measuring component 3 is clean.

[0055] Specifically, the blowing component 4 can blow air to the distance measuring component 3 continuously, or blow air to the distance measuring component 3 occasionally, or blow air to the distance measuring component 3 at any time according to demand, and adjust the blowing time according to demand.

[0056] According to actual experience on site, since the replenishment material in the storage bin 1 is dropped from the upper crane, it is easy to cause the shape of the material on the bottom belt 11 to be uneven and pyramid-shaped. When the material is transported from the bottom belt 11 to the lifting belt, it is easy to cause the thickness of the material at the bottom of the elevator 2 to be uneven. In addition, the conveying rates of the bottom belt 11 and the lifting belt are inconsistent, which further aggravates the uneven thickness phenomenon, making it easy for the material thickness to be uneven in the middle section of the elevator 2, and even further causing material shortage.

[0057] Existing photoelectric tubes and photoelectric switches can only detect whether there is material at a certain position, but cannot detect the amount of material. In addition, photoelectric tubes and photoelectric switches are easily blocked by materials, resulting in material errors in the detection results when there is a lack of material, which in turn causes uneven materials in the subsequent equipment of the elevator 2, affecting the process of the tobacco process. The distance measuring component 3 of this embodiment can detect the thickness of the material and determine whether the material is uniform by the thickness, thereby reminding the operator whether to perform the material replenishment operation, providing a stable flow of materials for the subsequent equipment, and ensuring the quality of production.

[0058] At the same time, when the distance measuring component 3 is at risk of being blocked by materials or dust, the blowing component 4 can blow away the blocking objects of the distance measuring component 3, ensuring that the distance measuring component 3 can always reliably measure the distance of the material, thereby improving the reliability of the operation of the distance measuring component 3.

[0059] As can be seen from the above, the tobacco feeding device of the utility model, by arranging the distance measuring component 3 and the blowing component 4 on the elevator 2, enables the distance measuring component 3 to detect the material thickness in the area prone to material breakage in real time, and the distance measuring component 3 can also move in the area prone to material breakage of the elevator 2 to realize the detection of the material thickness at each position in the area, so that the operator can replenish the elevator 2 in time according to the detected thickness information, thereby ensuring the stability of the material flow on the elevator 2, and, by blowing air to the distance measuring component 3 through the blowing component 4, the cleanliness of the environment around the distance measuring component 3 is ensured, and measurement errors caused by the distance measuring component 3 being blocked are avoided, thereby improving the reliability of the measurement of the distance measuring component 3, ensuring the quality stability of tobacco production and improving production efficiency.

[0060] In some embodiments, Figure 1 and Figure 3 As shown, the distance measuring assembly 3 of this embodiment includes a sliding support 31 and a distance measuring sensor 32 .

[0061] The sliding support 31 is movably disposed on the steel beam 21 of the hoist 2 , and the distance measuring sensor 32 is rotatably disposed on the sliding support 31 .

[0062] It is understandable that in this embodiment, the movement of the sliding support 31 relative to the steel beam 21 can be achieved through the cooperation of the gear and the rack, and the movement of the sliding support 31 relative to the steel beam 21 can also be achieved through a screw transmission mechanism.

[0063] At the same time, in this embodiment, a cam mechanism may be provided to realize the rotation of the distance measuring sensor 32 relative to the sliding support 31 , or a crank mechanism may be provided to realize the rotation of the distance measuring sensor 32 relative to the sliding support 31 .

[0064] In this embodiment, the sliding support 31 is movably arranged on the steel beam 21, and the distance measuring sensor 32 is rotatably arranged on the sliding support 31, so that the distance measuring sensor 32 can rotate relative to the sliding support 31 to adjust the optimal distance measuring position. At the same time, the distance measuring sensor 32 and the sliding support 31 can move as a whole relative to the steel beam 21 to detect materials at different positions in the easy-to-break material area of ​​the elevator 2, so that the thickness of the material in the easy-to-break material area can be collected and detected in all directions, thereby improving the accuracy of the material thickness test.

[0065] In some embodiments, Figure 1 As shown, the distance measuring assembly 3 of this embodiment further includes a first driving member 33 .

[0066] The first driving member 33 is disposed on the steel beam 21 , and an output end of the first driving member 33 is connected to the sliding support 31 . The first driving member 33 is used to drive the sliding support 31 to move along the extension direction of the steel beam 21 .

[0067] The steel beam 21 is provided with a slide rail, and the slide rail is extended along the extension direction of the steel beam 21 .

[0068] The sliding support 31 is provided with a pulley, and the pulley is movably arranged on the slide rail.

[0069] It is understandable that the first driving member 33 may be a motor.

[0070] In this embodiment, by setting the first driving member 33, the sliding support 31 can move along the steel beam 21 based on the cooperation of the pulley and the slide rail, thereby driving the distance measuring sensor 32 to move between the first position P1 and the second position P2 along the steel beam 21. Not only is the structure of the distance measuring component 3 simple, but the movement speed is fast, and the efficiency of adjusting the position of the distance measuring component 3 is high.

[0071] In some embodiments, Figure 1 and Figure 3 As shown, the distance measuring assembly 3 of this embodiment further includes a second driving member 34 .

[0072] The second driving member 34 is disposed on the sliding support 31 , and an output end of the second driving member 34 is connected to the distance measuring sensor 32 . The second driving member 34 is used to drive the distance measuring sensor 32 to rotate.

[0073] It is understandable that, in the process of the distance measuring sensor 32 moving from the first position P1 to the second position P2, it is necessary to timely adjust the angle of the distance measuring sensor 32 so that the distance measuring sensor 32 is always aligned with the material in the easy-to-break area.

[0074] The second driving member 34 may be a stepping motor.

[0075] The second driving member 34 of this embodiment can drive the distance measuring sensor 32 to rotate, thereby adjusting the detection angle of the distance measuring sensor 32, ensuring the accuracy of material testing, and can conveniently adjust the test angle of the distance measuring sensor 32, thereby improving the efficiency of adjusting the angle and facilitating operation.

[0076] In some embodiments, Figure 1 As shown, the distance measuring component 3 of this embodiment further includes: a limiting member.

[0077] The limiting member is disposed at the first position P1 and the second position P2 of the slide rail, and the limiting member limits the moving position of the sliding support 31 .

[0078] It is understandable that when the distance measuring component 3 moves relative to the slide rail, setting limit members at the first position P1 and the second position P2 can prevent the moving path of the distance measuring component 3 from exceeding the easy-to-break material area of ​​the elevator 2, thereby ensuring the reliability of the movement of the distance measuring component 3.

[0079] The limiting member may be a limiting block.

[0080] In some embodiments, the distance measuring sensor 32 of this embodiment is a laser distance measuring device.

[0081] It can be understood that the measurement accuracy of the laser rangefinder can reach the millimeter level, and it has strong anti-interference ability and stable ranging state.

[0082] The laser rangefinder of this embodiment can accurately detect the thickness of the material, improve the accuracy of material detection, and ensure the stability of the detection result.

[0083] In some embodiments, Figure 1 and Figure 2 As shown, the blowing assembly 4 of this embodiment includes a compressed air source, a nozzle and a control valve 41.

[0084] The compressed air source is connected to the nozzle through a pipeline, and the nozzle is used to blow air to the distance measuring component 3.

[0085] The control valve 41 is arranged on the pipeline between the compressed air source and the nozzle.

[0086] It is understandable that the compressed air source provides a stable and continuous air source for the blowing component 4, and the compressed gas is ejected from the nozzle to blow the distance measuring component 3, and the opening and closing of the control valve 41 can control the blowing and stopping of the nozzle.

[0087] The compressed gas source may be compressed air, and the control valve 41 may be a manual control valve 41 or an electric or pneumatic control valve 41 .

[0088] In this embodiment, a compressed air source, a nozzle and a control valve 41 are arranged in the blowing component 4, so that the compressed air source provides compressed gas to the nozzle, so that the nozzle can blow air to the ranging component 3, and the control valve 41 can also be used to control the start and stop of the nozzle, thereby realizing a flexible adjustment function.

[0089] In some embodiments, Figure 1 and Figure 2 As shown, the tobacco feeding device with the function of preventing material interruption in this embodiment further includes: a controller 5 and an alarm 6.

[0090] The distance measuring component 3 is connected to the controller 5 , and the controller 5 is connected to the alarm 6 .

[0091] The controller 5 controls the working state of the alarm 6 according to the material thickness information fed back by the distance measuring component 3 .

[0092] It is understandable that when conveying materials, if the material thickness in the area of ​​the elevator 2 that is prone to material breakage is uneven, or there is a shortage of material, and the thickness value is lower than a certain range of the preset value, the controller 5 controls the alarm 6 to sound an alarm, so that the operator is informed that the thickness in the area of ​​the elevator 2 that is prone to material breakage does not meet the requirements, and responds in time.

[0093] Among them, the alarm 6 can be a buzzer. When the thickness of the area prone to material breakage is uneven, the buzzer will emit a sound alarm. The alarm 6 can also be an audible and visual alarm. When the thickness of the area prone to material breakage is uneven, the audible and visual alarm will emit a sound alarm and a light alarm.

[0094] In this embodiment, by providing an alarm 6, when the thickness of the area prone to material breaking is uneven, an alarm can be automatically sounded to remind the operator, without excessive manual intervention, thereby improving the efficiency of transportation.

[0095] In some embodiments, Figure 1 and Figure 2 As shown, the storage bin 1 of this embodiment includes a bottom belt 11 and a third driving member 12 .

[0096] An output end of the third driving member 12 is connected to the bottom belt 11 .

[0097] The controller 5 is connected to the third driving member 12 .

[0098] The controller 5 controls the start, stop and speed of the third driving member 12 according to the thickness information fed back by the distance measuring component 3 .

[0099] It is understandable that when the thickness of the area prone to material breakage is uneven, it is necessary to start the bottom belt 11 in time to replenish the elevator 2 to avoid instability of the material in the subsequent equipment of the elevator 2.

[0100] The third driving member 12 may be a motor.

[0101] In this embodiment, the third driving member 12 is provided so that when the thickness of the area prone to material breakage is uneven, based on the thickness information fed back by the distance measuring component 3 to the controller 5, the controller 5 can control the third driving member 12 to drive the bottom belt 11 to run and automatically replenish the elevator 2. Alternatively, when the thickness is too large, the bottom belt 11 can be controlled to stop in time to prevent the accumulation of materials in the elevator 2. At the same time, the controller 5 can also control the speed of the third driving member 12, thereby controlling the conveying speed of the bottom belt 11, and then controlling the conveying speed of the material, so as to achieve precise control of the replenishing height on the elevator 2, thereby further improving the uniformity of the material in the elevator 2.

[0102] In some embodiments, Figure 1 and Figure 2 As shown, the controller 5 of this embodiment is connected to the control valve 41 ; the controller 5 controls the start and stop of the control valve 41 .

[0103] It is understandable that when the blowing component 4 blows air to the distance measuring component 3, occasional blowing, or changing the number of blowing times and blowing duration according to the on-site conditions can be achieved by controlling the start and stop states of the control valve 41 through the controller 5, thereby realizing automatic control of the blowing of the distance measuring component 3 and improving the efficiency of blowing.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
