Description
Technical Field
The invention relates to the technical field of tobacco processing equipment and methods, in particular to a threshing method for threshing and redrying production, and especially relates to a dynamically adjustable multi-layer frame fence threshing device.
Background
The existing horizontal threshing method for threshing and redrying production is based on a single-layer frame fence threshing device. As shown in FIG. 1, the frame structure of the single-layer frame threshing device is an integral frame with an opening and a semicircular arc cylindrical surface.
The one-time complete threshing method in the prior art comprises the following steps:
(1) When the tobacco leaves enter the threshing device from the feeding hole of the threshing device, the tobacco leaves are driven by the rotation of the threshing roller 1 rotating at a high speed to form tobacco leaf flows along the rotation direction;
(2) Under the action of centrifugal force, the tobacco leaves are thrown to the frame columns 2. Because of the large speed difference between the movable beating knife 3 on the beating rod 1 and the frame fence 2 and the fixed beating knife 4, a certain force is generated and acts on tobacco leaves, and the edges at the opening of the frame fence and the beating knife tear the leaves from tobacco stems;
(3) The torn leaves, the stems with leaves, the pure stems and the like fall from the opening and are discharged from the lower discharge port of the threshing machine body 5 when the external shape size is smaller than the opening size of the frame rail. Thus, the materials are continuously fed and continuously discharged, and a continuous threshing process is formed.
(4) Stopping the machine, and manually replacing the frame columns with openings of different sizes;
(5) Repeating the steps (2) - (4) until the threshing is completed.
In summary, the size of the opening of the frame rail has a larger influence on the size of the discharge size of the threshing method, and in the continuous threshing process, the method for adjusting the threshing parameters is needed to adjust the size of the discharge size in order to improve the threshing quality.
Therefore, in the existing single-layer frame-column horizontal threshing method, in order to change the size of the discharge size, frame columns with different opening sizes need to be manually replaced in an integral manner in a shutdown state. Because the size of each frame column opening is fixed, the frame columns with different size frame column openings serving as accessories cannot be too large in specification, and the frame columns are difficult to replace repeatedly in the threshing process, so that the situation that the threshing quality needs to be improved is caused by adopting the traditional threshing method of a single-layer frame column.
Therefore, the existing single-layer frame-column horizontal threshing method has the defects that production is stopped due to the fact that the frame columns are required to be replaced manually, efficiency is reduced, labor is wasted, time is wasted, labor intensity is high, and the development of fine adjustment and control of quality indexes of the blades after threshing is restricted. .

(2) Under the action of centrifugal force, tobacco leaf materials are thrown to the multi-layer frame fence device 21/22. Because of the large speed difference between the dynamic threshing blade 3 on the threshing rod 1 and the upper frame 211/221 and the fixed threshing blade 4 in the multi-layer frame device 21/22, a certain force is generated and acts on tobacco leaves, and the edges at the opening of the frame and the threshing blade tear the leaves from tobacco stems;
(3) The torn leaves, the stems with leaves, the pure stems and the like fall from the opening and are discharged from the lower discharge hole of the threshing machine body 5 when the external shape size is smaller than the opening size of the frame rail;
(4) The blade structure detection system detects the shape and the size of the tobacco leaves discharged from the discharge port in real time (such as the large sheet rate, the middle sheet rate, the fragment rate and the like obtained by the real-time detection of the blade structure detection system), automatically adjusts the actual discharge opening size of the frame rail according to the appointed size of the blade structure index, adapts to the discharge requirement, and realizes the dynamic balance adjustment of each threshing quality index so as to improve the threshing quality index;

The frame opening of the upper frame and the frame opening of the lower frame are mutually combined to form the actual discharge opening size of the frame, and the actual discharge opening size of the frame can be adjusted by moving the lower frame.

Embodiment one:

Wherein, the multi-layer frame fence device 21 is arranged below the beating stick 3 and is arranged in the machine body 5.
The multi-layer frame rail device 21 shown in fig. 5 includes: an upper frame rail 211 fixedly installed, a lower frame rail 212 capable of moving radially, a frame rail bracket 213 installed below the lower frame rail, and a radial rotation driving mechanism 214; the radial rotation driving mechanism 214 comprises a motor 2141 and a linkage mechanism 2142; the linkage mechanism 2142 is a crank-slider mechanism; the motor 2141 is a stepper motor.
The dynamically adjustable implementation of the multi-layer frame rail device 21 is: the lower frame 212 is driven by the radial rotation driving mechanism 214 to rotate along the radial direction on the outer surface of the upper frame 211, and the dislocation between the frame opening of the lower frame 212 and the frame opening of the upper frame 211 changes, so that the actual discharge size at the frame opening changes accordingly, the dynamic adjustment of the actual discharge size at the frame opening is realized, and the control of the discharge size of the thresher is realized.
The embodiment also comprises a blade structure detection system 6 which can detect the shape and the size of the tobacco leaf materials discharged from the discharge hole in real time.

Since the frame opening of the lower frame 212 is offset from the frame opening of the upper frame 211, the actual discharge size SK at the frame opening is changed. The torn leaves, the stems with the leaves and the pure stems only fall from the opening and are discharged from the lower discharge hole of the threshing machine body 5 when the sizes of the torn leaves, the stems with the leaves and the pure stems are smaller than the actual discharge size of the opening of the frame fence.

At the same time, the actual discharge size SK at the opening of the frame rail changes, which results in the change of the size of the tobacco leaves which fall from the opening and are discharged from the lower discharge opening of the threshing machine body 5.
If the tobacco leaf mass ratio exceeds the standard, the image recognition processing and control system 63 controls the electric driving mechanism 214 to rotate forward and drives the lower frame column 212 to rotate anticlockwise; the frame opening of the lower frame 212 and the frame opening of the upper frame 211 are staggered by a large amount, the actual discharging size SK at the frame opening is reduced, the size of tobacco leaves falling from the opening and discharged from the lower discharging hole of the threshing machine body 5 is reduced, the blade large-scale rate is reduced, and the fragment rate is correspondingly increased. The shape and the size of the tobacco leaf materials discharged from the discharge hole (such as the large sheet rate and the fragment rate obtained by the real-time detection of the blade structure detection system 6) are subjected to uninterrupted real-time detection, data transmission feedback and frame and fence adjustment; PID adjustment is carried out on the size (the large sheet rate) of the adjusting and controlling blade, and dynamic adjustment on the index of the large sheet rate of the blade is realized.
(II) if the tobacco leaf breakage rate exceeds the standard, the image recognition processing and control system 63 controls the electric driving mechanism 214 to rotate reversely and drives the lower frame column 212 to rotate clockwise; the frame opening of the lower frame 212 and the frame opening of the upper frame 211 are offset by a small amount, the actual discharging size SK of the frame opening is increased, the size of the tobacco leaves falling from the opening and discharged from the lower discharging hole of the threshing machine body 5 is increased, the leaf fragment rate is reduced, and the large leaf fragment rate is correspondingly increased. The shape and the size of the tobacco leaf materials discharged from the discharge hole (such as the large sheet rate and the fragment rate obtained by the real-time detection of the blade structure detection system 6) are subjected to uninterrupted real-time detection, data transmission feedback and frame and fence adjustment; PID adjustment is carried out on the blade debris rate to be regulated and controlled, and dynamic adjustment of blade debris rate indexes is achieved.

The conveying equipment conveys tobacco leaves to a feed inlet of the threshing device; when the tobacco leaves enter the threshing device from the feeding hole of the threshing device, the tobacco leaves are driven by the threshing roller 1 rotating at high speed to form tobacco leaf flows. Under the action of centrifugal force, the tobacco leaves are thrown towards the multi-layer frame rail device 22. Because of the large speed difference between the movable beating blade 3 on the beating rod and the upper frame fence 221 and the fixed beating blade 4, a certain force is generated to act on tobacco leaves, and the edges and the beating blades at the opening of the upper frame fence 221 tear the leaves from tobacco stems. Since the frame opening of the lower frame 222 is offset from the frame opening of the upper frame 221, the actual discharge size SK at the frame opening is changed. The torn leaves, the stems with the leaves and the pure stems only fall from the opening and are discharged from the lower discharge hole of the threshing machine body 5 when the sizes of the torn leaves, the stems with the leaves and the pure stems are smaller than the actual discharge size of the opening of the frame fence.
