Description

Technical Field

[0001] This utility model relates to the field of cigarette production technology, and in particular to an anti-clogging device and a loosening and rehydration machine. Background Technology

[0002] In cigarette production, loosening and rehydration is a crucial step in the process. It utilizes a combination of mechanical loosening and hot steam penetration to loosen the tobacco clumps (composed of tobacco leaves) and increase their moisture content. This improves the leaves' resistance to breakage, meeting the requirements of subsequent processing steps such as adding and shredding. The loosening and rehydration process not only affects the physical quality of the processed tobacco leaves but also significantly impacts their aroma and sensory qualities.

[0003] Currently, loosening and rehydration machines are generally equipped with a feeding channel at the inlet end, through which materials can be conveyed into the loosening and rehydration machine. When it is necessary to loosen and rehydrate tobacco blocks, the tobacco blocks usually need to be sliced ​​and then conveyed to the loosening and rehydration machine through the feeding channel for loosening and rehydration treatment. However, due to the different shapes and sizes of the sliced ​​tobacco blocks, the tobacco blocks often block the feeding channel, resulting in the problem of not being able to feed normally. Utility Model Content

When the push plate is in the first position, it is completely outside the feed channel. When the push plate is in the second position, it is at least partially inside the feed channel. The push plate is used to push the material in the feed channel into the loosening and rehydration machine. The drive mechanism is connected to the push plate and is used to drive the push plate to reciprocate between the first position and the second position. The control mechanism is electrically connected to the detection mechanism and the drive mechanism. The detection mechanism can send a signal to the control mechanism. When the duration of the signal is greater than or equal to a preset time, the control mechanism controls the drive mechanism to move the push plate from the first position to the second position.

The detection unit is located downstream of the pusher plate along the material conveying direction. The detection unit includes a transmitting sensor and a receiving sensor, which are located on both sides of the feed channel along the width direction of the feed channel. The transmitting sensor can emit light signals toward the receiving sensor, and the receiving sensor is used to receive the light signals. The area through which the light signals pass is the detection area. The output unit is electrically connected to both the receiving sensor and the control mechanism. The output unit is used to send a signal to the control mechanism when the receiving sensor does not receive a light signal.

The second connecting rod is perpendicular to both the first connecting rod and the rotating shaft. One end of the second connecting rod is connected to the other end of the first connecting rod, and the other end of the second connecting rod is connected to a push plate. The motor is connected to the rotating shaft and is used to drive the rotating shaft to rotate.

[0009] According to another specific embodiment of the present invention, the drive mechanism further includes a transmission component disposed between the motor and the rotating shaft, and the transmission component is used to transmit power between the motor and the push plate.

[0010] According to another specific embodiment of this utility model, the transmission assembly includes a driving pulley, a driven pulley, and a belt.

[0026] Currently, when it is necessary to loosen and rehydrate tobacco blocks, the tobacco blocks are usually sliced ​​and then fed into a loosening and rehydration machine through the feeding channel for loosening and rehydration treatment. However, due to the different shapes and sizes of the sliced ​​tobacco blocks, the tobacco blocks often block the feeding channel, resulting in the inability to feed normally.

[0027] To solve the above-mentioned technical problems, this utility model provides an anti-blocking device, which can prevent the feed channel of the loosening and rehydration machine from becoming blocked and ensure normal feeding.

[0028] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below.

[0029] refer to Figure 1 and Figure 2This application provides an anti-clogging device, including a detection mechanism 1, a pusher plate 2, a drive mechanism 3, and a control mechanism (not shown in the figure). The anti-clogging device provided in this application is located at the feed end 4 of a loosening and rehydration machine. The feed end 4 of the loosening and rehydration machine is provided with a first direction (e.g., ...). Figure 1 The feed channel 5 extends in the X direction (as shown in the figure), through which materials can be conveyed to the loosening and rehydration machine.

[0030] For details, please refer to Figure 1 and Figure 2 A detection mechanism 1 is disposed on the feed channel 5. The detection mechanism 1 is used to detect the presence of material within its detection area and outputs a signal when material is detected. The detection mechanism 1 includes a detection unit 11 and an output unit 12. The detection unit 11 includes a transmitting sensor 111 and a receiving sensor 112, which are disposed on both sides of the feed channel 5 along its width direction. For example, the feed channel 5 includes a second direction (e.g., ...). Figure 1 The two side walls 51 (shown in the Y direction) are arranged at intervals, each with a viewing window 511 positioned opposite each other. A transmitting sensor 111 and a receiving sensor 112 are respectively located on the side of the two viewing windows 511 away from the feed channel 5. The transmitting sensor 111 emits a light signal towards the receiving sensor 112, which receives the light signal. The area through which the light signal passes is the detection area. The output unit 12 is electrically connected to the receiving sensor 112 and outputs a signal when the receiving sensor 112 does not receive a light signal.

[0031] refer to Figure 1 The pusher plate 2 is positioned above the feed channel 5, and the detection unit 11 is positioned downstream of the pusher plate 2 along the material conveying direction. The pusher plate 2 can reciprocate between a first position and a second position. For example, as shown... Figure 3 As shown, the trajectory of the pusher 2 (e.g.) Figure 3 The trajectory L (as shown in the diagram) can be arc-shaped, with the first position M and the second position N being the two ends of the arc. The first position is higher than the second position, and the first position is located between the second position and the inlet end 52 of the feed channel 5 (i.e., along the X direction, the first position is closer to the inlet end 52 than the second position). When the pusher plate 2 is in the first position, the pusher plate 2 is completely outside the feed channel 5. When the pusher plate 2 is in the second position, the pusher plate 2 is at least partially inside the feed channel 5. When the pusher plate 2 moves from the first position to the second position, the pusher plate can push the material in the feed channel 5 into the loosening and rehydration machine.

[0032] refer to Figure 1 The drive mechanism 3 is connected to the push plate 2, and the drive mechanism 3 is used to drive the push plate 2 to move back and forth between the first position and the second position.

[0033] Furthermore, the control mechanism is electrically connected to the output unit 12 on the detection mechanism 1. When the receiving sensor 112 does not receive a light signal (i.e., there is material in the detection area blocking the light signal), the output unit 12 outputs a signal to the control mechanism. The control mechanism includes a timer and a processor. The timer is used to calculate the duration of the signal. The processor is electrically connected to the timer and is used to receive the duration calculated by the timer and compare the duration with a preset time. For example, the preset time can be 3 seconds. The control mechanism is electrically connected to the drive mechanism 3. When the duration of the signal is greater than or equal to the preset time, the control mechanism controls the drive mechanism 3 to start, driving the pusher plate 2 to move from the first position to the second position, so as to push the material in the feed channel 5 into the loosening and rehydration machine.

[0034] When the receiving sensor 112 on the detection mechanism 1 does not receive the light signal emitted by the transmitting sensor 111, it indicates that there is material in the detection area, blocking the light signal. At this time, the output unit 12 on the detection mechanism 1 outputs a signal to the control mechanism. When the control mechanism receives the signal, the timer starts counting to calculate the duration of the signal. If the signal disappears, the timer is reset to zero. The timer restarts when the control mechanism receives the signal again. The processor compares the duration of the signal calculated by the timer with the preset time. When the duration of the signal is greater than or equal to the preset time, it indicates that the material has been staying in the detection area for too long, exceeding the normal conveying speed of the material, and it is determined that a blockage has occurred in the feed channel 5. Subsequently, the control mechanism controls the drive mechanism 3 to start, driving the push plate 2 to move from the first position to the second position to push the blocked material in the feed channel 5 into the loosening and rehydration machine to clear the feed channel 5. Then the drive mechanism 3 drives the push plate 2 to automatically reset to the first position, waiting for the next instruction. In this embodiment, when a blockage occurs in the feed channel 5, the blocked material can be pushed into the loosening and rehumidifying machine to clear the feed channel 5 and ensure normal feeding of the loosening and rehumidifying machine.

[0035] Optionally, refer to Figure 1The drive mechanism 3 includes a motor 31, a rotating shaft 32, a first connecting rod 33, and a second connecting rod 34. The rotating shaft 32 extends along a second direction and is rotatably positioned above the feed channel 5. Exemplarily, a bracket 6 is provided on the side wall 51 of the feed channel 5, and the end of the rotating shaft 32 is hinged to the bracket 6. The rotating shaft 32 can rotate about its own axis, and during rotation, it can drive the push plate 2 to reciprocate between a first position and a second position. The first connecting rod 33 extends radially along the rotating shaft 32, and one end of the first connecting rod 33 is connected to the rotating shaft 32. The second connecting rod 34 is perpendicular to both the first connecting rod 33 and the rotating shaft 32. One end of the second connecting rod 34 is connected to the other end of the first connecting rod 33, and the other end of the second connecting rod 34 is connected to the push plate 2. The motor 31 is connected to the rotating shaft 32 and is used to drive the rotating shaft 32 to rotate. The drive mechanism 3 also includes a transmission assembly 35 disposed between the motor 31 and the rotating shaft 32. The transmission assembly 35 is used to transmit power between the motor 31 and the push plate 2. For example, as shown... Figure 1 As shown, the transmission assembly 35 includes a driving pulley 351, a driven pulley 352, and a belt 353. The driving pulley 351 and the driven pulley 352 are hinged to the side wall 51. The driving pulley 351 is connected to the output end of the motor 31, and its axis is parallel to the second direction. The driving pulley 351 can rotate around its own axis under the drive of the motor 31. The driven pulley 352 is located directly above the driving pulley 351, and the axis of the driven pulley 352 coincides with the axis of the rotating shaft 32. The driving pulley 351 can drive the driven pulley 352 to rotate around its own axis. The driven pulley 352 is connected to the rotating shaft 32 and is used to drive the rotating shaft 32 to rotate. The belt 353 is disposed between the driving pulley 351 and the driven pulley 352, and the belt 353 is used to transmit power between the driving pulley 351 and the driven pulley 352.

[0036] When the detection mechanism detects a blockage in the feed channel 5, the control mechanism first controls the motor 31 to run in the forward direction. The motor 31 drives the rotating shaft 32 along the transmission assembly 35. Figure 3 The material in the feed channel 5 rotates counterclockwise (R1), driving the pusher plate 2 to move from the first position M to the second position N, thus pushing the blocked material into the loosening and rehydration machine. Subsequently, the control mechanism controls the motor 31 to run in the opposite direction, and the motor 31 drives the rotating shaft 32 along the […]. Figure 3 The clockwise rotation of R2 causes the push plate 2 to reset to the first position M, waiting for the next instruction.

[0037] Optionally, the anti-blocking device provided in this embodiment of the application further includes an alarm (not shown in the figure). The alarm is electrically connected to the control mechanism. When the duration of the signal is greater than or equal to a preset time, the control mechanism controls the alarm to sound an alarm. By setting an alarm, this embodiment of the application can promptly remind the operator that a blockage has occurred in the feed channel 5, so that the operator can check whether the feed channel 5 has been cleared.

[0038] Optionally, push plate 2 is made of stainless steel. Stainless steel has good corrosion resistance, which can improve the service life of push plate 2.

[0039] This application embodiment also provides a loosening and rehumidifying machine, including any of the aforementioned anti-clogging devices, and further including a rotating drum, a humidifying mechanism, and a guide plate. The rotating drum has a feed channel 5 at its feed end, and the rotating drum can rotate around its own axis. The humidifying mechanism is used to supply water vapor into the rotating drum to humidify the material. The guide plate is disposed on the inner wall of the rotating drum, and the guide plate is used to disperse the material when the rotating drum rotates.
