Description
Technical Field
The invention relates to a debugging and verifying method and equipment for a double-medium nozzle.
Background
The tobacco leaf moistening and feeding are important processes in the tobacco shred production process, and the process aims to uniformly spray sugar and water on the tobacco flakes and balance the moisture content of incoming materials so as to be beneficial to further processing the tobacco leaves in subsequent processes. Wherein, the control effect of the water content has an important effect on the internal quality of the cut tobacco, and the atomization effect of the feeding nozzle for applying the feed liquid can directly influence the absorption effect of the sugar material of the tobacco leaves.
At present, a barrel nozzle is widely applied to roller equipment in a cigarette production and tobacco shred manufacturing link, mainly plays a role in humidifying, perfuming and charging tobacco (leaf) shreds, and the injection angle of the nozzle directly influences the humidifying, perfuming and charging uniformity of on-line tobacco flakes and tobacco shreds, so that the stability of the on-line product quality is realized. The double-medium nozzle debugging and verifying method has two important technical indexes, namely nozzle angle and nozzle atomization size. The two indexes directly influence the absorption uniformity of the tobacco leaves on moisture and sugar and the control stability of the moisture content.
The optimum spray angle of the nozzle is determined by both radial and axial directions:
① radial angle, positioning according to the falling position of the material, rotating the roller clockwise, allowing the tobacco leaf to fall along the top of the parabolic curve at about 11 o' clock position of the roller, during free fall, the tobacco leaf is in suspension state and loose, and the absorption effect of the added feed liquid is good, so the feed liquid can be completely atomized when the atomization region of the nozzle falls at the five-pointed star position in figure 1.
② axial angle, optimized according to the diameter of the roller, when the nozzle is too close to the feed end, the feed liquid is blown out by the injection medium, and meets the opposite wall of the roller without full atomization, and liquid feed liquid is easily formed on the wall of the roller, and the feed liquid can not be atomized fully, when the nozzle is far away from the feed end, the feed liquid atomization area does not fall on the material falling area, and the tobacco leaf can not absorb the feed liquid fully, therefore, the nozzle needs to be positioned in the radial and axial directions (D and E in figure 1).
In the actual production process, the nozzle angle adjustment has the following problems:
1. in the adjustment process of the nozzle of the cylinder body, the adjustment of the angle of the nozzle by maintenance personnel mainly takes the debugging and verification of the strip material and the visual observation;
2. due to the existence of two dimensions, namely the axial dimension and the longitudinal dimension, certain errors exist in the point position searching through the tape measure;
3. after adjustment, the accurate point position can be found by reworking for many times.
In the actual production process, the nozzle angle is usually adjusted by the experience of maintenance personnel, and the axial and longitudinal angle standards cannot be quantified. Therefore, a duplex nozzle positioning device capable of being accurately adjusted needs to be developed so as to realize accurate positioning of the nozzle in the axial direction and the radial direction, guarantee the consistency of the front and rear angles of the nozzle during disassembly and assembly, guarantee no change of the atomizing size of the nozzle during long-term use, and improve the uniformity of liquid application.
The three main lines for making the silk are arranged in our factory, and the consistency of the three lines.

As a further improvement, the side wall of the fixed shaft sleeve is provided with a screw hole, and the laser pen is fixedly arranged on the fixed shaft sleeve through the arrangement of a fastening screw.
The invention firstly considers the distance between the point to be measured and the end surface of the cylinder, thus adopting the laser ranging device to measure the linear distance. Meanwhile, in order to ensure that the measuring device and the point to be measured are in the same plane, at least two points of the end surface of the measuring space are determined. Therefore, the laser distance measuring device needs to be designed to be movable, i.e. the distance measuring device is installed on the sliding block. The slide block slides linearly with the guide rail by using steel balls, and the guide rail is positioned in the middle of the main frame. Since the horizontal distance from the point to be measured to the wall of the cylinder on the other side is determined in the radial direction, a placeable rod piece with the required length and a horizontal calibration device are required. Therefore, a level gauge is embedded in the side surface of the main frame, and one end of the main frame is provided with a square telescopic rod frame with scales (different barrel horizontal distances are different). After the positioning point is found by the device, the angle of the nozzle needs to be adjusted until the jet orifice of the nozzle and the tail part of the nozzle are in a linear state with the positioning point. Therefore, the laser pointer positioning device is used for implementation. The tail structure of the laser pen can be inserted into the nozzle opening, and the nozzle can be rotated to adjust the angle by shaking the laser pen until the laser pen is aligned with the positioning point.
The optimal spray angle of the dual-medium nozzle is determined by the radial direction and the axial direction:
① radial angle, positioning according to the falling position of the material, rotating the roller clockwise, allowing the tobacco leaf to fall along the top of the parabolic curve at about 11 o 'clock position of the barrel 3, during free fall, the tobacco leaf is in suspension state and loose, and the absorption effect of the added feed liquid is good, so the feed liquid can be completely atomized when the atomization region of the nozzle falls at 11 o' clock position.
②, the angle is optimized according to the diameter of the roller, when the nozzle is too close to the feed end, the feed liquid is blown out by the injection medium steam, and the feed liquid meets the opposite roller wall without being completely atomized, so that the liquid feed liquid is easily formed on the roller wall and cannot be sufficiently atomized, and when the nozzle is far away from the feed end, the feed liquid atomization area does not fall on the material falling area, and the tobacco leaves cannot sufficiently absorb the feed liquid.
The invention adopts the movable laser ranging device to accurately measure the axial dimension, the telescopic ruler is matched with the level gauge to determine the radial dimension, and the laser pen kit is utilized to adjust the nozzle, so as to realize the rapid positioning of the nozzle angle, save the labor cost and greatly improve the working efficiency.
According to the invention, the final nozzle angle and the nozzle atomization size are determined through the multi-batch production of material passing of the real object and the analysis of the result of the finished cigarette smoking evaluation by the technical center. After a positioning block is additionally arranged on the double-medium nozzle, the atomizing size is ensured to be unchanged. And then the accurately adjustable double-medium nozzle positioning device is utilized to accurately position the angle axial direction and the radial direction of the feeding nozzle and the water adding nozzle, so that the angle of the nozzle can be ensured to obtain sufficient data quantization.
