As shown in fig. 1, the method for detecting the thickness of a cigarette layer in a lower mouth of a cigarette packaging machine provided in this embodiment specifically includes the following steps in an actual implementation process:

step S1, placing detection pressing plate 9 above cigarette layer 12.

Wherein, the detection pressing plate 9 is a light, thin and smooth metal pressing plate. The material of the detection pressure plate 9 may be, for example, 304 stainless steel, and the thickness thereof is 0.8mm to 2mm, for example, 1mm, and the material, thickness, size, and the like of the detection pressure plate 9 are not particularly limited in the present invention.

Further, as shown in fig. 2, the detection pressing plate 9 includes a slant surface area and a cambered surface area located at the bottom of the slant surface area, and the slant direction of the slant surface area is consistent with the cigarette supply direction in the cigarette layer 12. The curvature of the arc surface area is 60 to 120 degrees, for example, 90 degrees, it should be noted that the invention is not limited to the curvature of the arc surface area.

Further, in an embodiment of the method for detecting a thickness of a cigarette layer of a lower mouth of a cigarette packaging machine of the present invention, the step S1 may specifically include:

the bottom of the detection pressing plate 9 is placed above the cigarette layer 12 of the packaging machine, and the upper part of the detection pressing plate 9 is connected with the gear transmission assembly 4.

Further, the detection pressure plate 9 is connected with the gear transmission assembly 4 through a bolt assembly. As shown in fig. 2, the detecting pressure plate 9 is connected to the gear transmission assembly 4 through two bolt assemblies located on the top of the detecting pressure plate 9, and it should be noted that the arrangement position and number of the bolt assemblies are not specifically limited in the present invention.

Further, will detect the bottom of clamp plate 9 and place the cigarette layer 12 top of packagine machine, specifically include:

the detection pressing plate 9 is naturally placed above the cigarette layer 12 by means of self gravity.

And step S2, when the cigarette layer 12 passes through the detection pressing plate 9, the inclination degree of the detection pressing plate 9 changes along with the change of the thickness of the cigarette layer.

In operation, when cigarette layer 12 passes through detection clamp plate 9, because detection clamp plate 9 is frivolous, it can not block the passing of cigarette layer, but can follow the change of cigarette layer thickness and the change of fluctuation in step, detects the inclination that clamp plate 9 also can change thereupon. For example, detecting the degree of inclination of the platen 9 can be measured by detecting the angle of inclination of the platen 9 with respect to the horizontal.

Step S3 is to transmit the change in the degree of tilt of the detection platen 9 to the angle sensor 6 synchronously via the gear transmission assembly 4.

In an embodiment of the method for detecting a cigarette layer thickness in a cigarette outlet of a cigarette packaging machine of the present invention, the step S3 may specifically include:

Step S32, the rotation of the gear in the gear transmission assembly 4 drives the angle of the angle sensor 6 connected to the gear transmission assembly 4 to change, so as to synchronously transmit the change of the inclination degree of the detection pressure plate 9 to the angle sensor 6.

And step S4, obtaining the real-time height of the smoke layer according to the angle signal acquired by the angle sensor 6.

Specifically, a controller connected with the angle sensor 6 is used for obtaining the real-time height of the smoke layer according to the angle signal collected by the angle sensor 6.

Further, the method for detecting the thickness of the cigarette layer of the lower cigarette opening of the cigarette packaging machine further comprises the following steps:

and step S5, adjusting the cigarette supply speed according to the real-time height of the cigarette layer.

When the controller calculates according to the angle signal to obtain the real-time height of the cigarette layer, the controller also simultaneously acquires the real-time running speed of the packing machine and matches the corresponding cigarette supply speed according to the running speed of the packing machine, when the packing machine runs at a high speed and the cigarette supply speed is lower, the thickness of the cigarette layer is reduced, the detection pressing plate 9 is reduced along with the reduction of the thickness of the cigarette layer, the angle feedback signal of the angle sensor 6 is sent to the controller, the conveying speed of a conveying belt of the connecting device is increased through the controller to improve the cigarette supply speed and increase the thickness of the cigarette layer; on the contrary, when the packer operates at low speed and the cigarette supply speed is higher, the cigarette layer thickness is increased, in order to avoid the blocking fault, the conveying speed of the conveying belt of the connecting equipment is reduced through the controller, so that the cigarette supply speed is reduced, and the cigarette layer thickness is reduced, therefore, the controller can control the speed of the conveying belt of the connecting equipment to change in real time, and the whole detection control process is automatically completed.

In an embodiment of the method for detecting a cigarette layer thickness in a cigarette outlet of a cigarette packaging machine of the present invention, the step S5 may specifically include:

step S51, the controller obtains voltage analog quantity according to the angle signal collected by the angle sensor and sends the voltage analog quantity to the servo controller;

step S52, the servo controller obtains the motor voltage according to the voltage analog quantity and sends the motor voltage to the controller;

and step S53, the controller controls the motor speed of the conveyer belt of the connecting device according to the motor voltage so as to adjust the cigarette supply speed.
