It should be noted that, in the case of no conflict, the embodiment in the application and the features in the embodiment can be combined with each other at will.

[0022] Please refer to Figs. 1-3 The laser reflection type tobacco warehouse detection device of the utility model embodiment is arranged on the tobacco warehouse hopper, and comprises the front guide plate 80 and the rear guide plate 90 located above the tobacco warehouse hopper, the laser emission receiver 10 arranged on one side of the rear guide plate 90, and the reflection plate assembly 20 connected to the side of the rear guide plate 90 away from the laser emission receiver 10, wherein the reflection plate assembly 20 comprises the reflection main plate 21 and the height adjusting assembly for adjusting the height of the reflection main plate 21, and the laser emission receiver 10 is electrically connected with the signal processor 30.

[0023] The utility model discloses a laser detection device for detecting whether the cigarette in the cigarette storehouse hopper is transverse or disorderly, and the laser detection device is used for avoiding the phenomenon of the lack or residual cigarette supply, and improving the working efficiency of the machine.

[0024] In order to facilitate the staff to process the transverse or disorderly cigarette in the cigarette storehouse hopper, the lower part of the front guide plate 80 is connected with a front movable door 60, and the lower part of the rear guide plate 90 is connected with a rear movable door 70. The front movable door 60 comprises a left door plate 61 and a right door plate 62, and the left door plate 61 and the right door plate 62 are hinged to the cigarette storehouse hopper through a pin shaft. The rear movable door 70 comprises an upper door plate 71 and a lower door plate 72, and the upper door plate 71 is hinged to the cigarette storehouse hopper through a pin shaft. When it is necessary to remove the transverse or disorderly cigarette in the cigarette storehouse hopper, the front movable door 60 or the rear movable door 70 is opened according to the area where the transverse or disorderly cigarette is located to process the transverse or disorderly cigarette.

[0025] In addition, the reflection plate assembly 20 comprises a reflection main plate 21 and a height adjusting assembly for adjusting the height of the reflection main plate 21. The height adjusting assembly comprises a screw rod 22 fixedly connected with the reflection main plate 21, an adjusting sleeve 23 threadedly connected with the screw rod 22, and a connecting seat 24 rotatably connected with the adjusting sleeve 23, wherein the connecting seat 24 is fixedly connected with the tobacco warehouse hopper. An operating handle is arranged on the adjusting sleeve 23. That is, when the height of the reflection main plate 21 needs to be adjusted, the operating handle is rotated to drive the adjusting sleeve 23 to rotate, and the screw rod 22 is threadedly connected with the adjusting sleeve 23. Since the adjusting sleeve 23 is installed on the connecting seat 24 and is rotatably connected with the connecting seat 24, the connecting seat 24 is fixedly connected with the tobacco warehouse hopper, and the adjusting sleeve 23 does not move in the vertical direction during rotation. Since the screw rod 22 is threadedly connected with the adjusting sleeve 23, the height of the screw rod 22 changes in the vertical direction during rotation of the adjusting sleeve 23, and the height of the screw rod 22 extending out of the adjusting sleeve 23 changes, which facilitates adjustment of the reflection main plate 21 to the optimal position, thereby reflecting the light beam emitted by the laser emission receiver 10, reducing the limitation of the installation position of the reflection main plate 21, and having a wide range of applications.

[0026] A light axis part is arranged on the screw rod 22, and the light axis part on the screw rod 22 is fixedly connected with the reflection main plate 21 through a bolt and a nut. A light-reflecting layer is arranged on one side of the reflection main plate 21 close to the laser emission receiver 10. The light-reflecting layer is made of aluminum foil.

[0027] The utility model discloses a laser emission receiver and reflection plate assembly installed in the back area of the tobacco warehouse hopper. Once the cigarettes in the back of the tobacco warehouse hopper are transversely arranged or disordered, the light beam emitted by the laser emission receiver will be blocked, the laser beam cannot return, the laser emission receiver does not receive the light beam, and a prompt signal is sent through the signal processor, which facilitates the staff to timely remove the transversely arranged or disordered cigarettes without stopping the machine, avoids the phenomenon of missing or residual cigarettes in the cigarette supply, ensures normal supply of the cigarette flow, and improves the working efficiency of the machine. In addition, the height adjusting assembly can adjust the height of the reflection main plate, which facilitates adjustment of the reflection main plate to the optimal position, thereby reflecting the light beam emitted by the laser emission receiver, reducing the limitation of the installation position of the reflection main plate, and having a wide range of applications.
