Description

Technical Field

[0001] The present invention relates to the technical field of cigarette production, and specifically to an on-line sampling and monitoring device for stem pieces. Background Art

[0002] In the current tobacco industry, the GD121 cigarette making machine is the main model for cigarette rolling in China. After the cut tobacco enters the GD121 cigarette making machine, it needs to be screened by a stem piece sorting device. The cut tobacco containing a certain amount of stem pieces is rolled into cigarette rods after passing through a throwing roller, while the separated stem pieces are directly discharged into the defluming pipeline to become waste under the action of the positive pressure air of the main fan. It should be noted that when the stem piece sorting device has a mechanical failure, it is easy to have the phenomenon of insufficient air pressure for stem piece sorting, resulting in quality defects such as surface punctures in the finished cigarettes; when the size of the stem piece sorting device is adjusted incorrectly, it is extremely easy for qualified finished cut tobacco to mix into the stem piece output pipeline, thus causing a large amount of waste of cut tobacco.

[0003] The invention with the publication number CN212325374U proposes an on-line sampling and monitoring device for stem pieces, which monitors the volume of stem pieces per unit time to judge whether the stem piece sorting device is operating normally. However, after the stem pieces are fed in, they will not be evenly placed, and there are gaps between them due to mutual accumulation, and it is difficult to monitor the actual blown-out amount of stem pieces by volume, resulting in a large monitoring error. Summary of the Invention

[0004] The purpose of the present invention is to provide an on-line sampling and monitoring device for stem pieces to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A bracket, which is arranged on an external fixing surface;

[0008] A monitoring box for on-line sampling and monitoring, which is arranged at the middle position of the left end of the bracket; and

[0009] A monitoring component for monitoring the number of stem pieces, which is arranged at the top of the bracket and extends into the monitoring box.

[0010] Further, the bracket includes a base, which is arranged on an external fixing surface. A support plate is arranged at the left side of the top of the base. An extension plate extends leftward from the top of the support plate. A connecting plate is arranged at the middle position of the left end of the support plate. The monitoring box is arranged at the left end of the connecting plate.

[0011] Further, the monitoring box includes a box body, a monitoring cavity is arranged inside the box body, and the bottom end of the monitoring cavity is open.

[0012] Further, a feeding port communicating with the monitoring cavity is arranged at the left end of the monitoring box, and the left end of the feeding port is communicated with the output end of the stem sorting device of the cigarette making machine.

[0013] Further, a sliding bearing is arranged at the middle position of the top end of the monitoring box, an installation groove is arranged on the upper side inside the monitoring cavity, and a barrier member is arranged in the installation groove.

[0014] Further, the barrier member includes an installation ring clamped in the installation groove, a filter screen is arranged inside the installation ring, a sliding cylinder is arranged at the middle position of the filter screen, and a contact ring is arranged at the bottom end of the sliding cylinder.

[0015] Further, a plurality of air outlet holes communicating with the monitoring cavity are uniformly arranged along the circumference at the upper end of the outside of the monitoring box, two groups of internal viewing ports are symmetrically arranged at the front and rear ends of the monitoring box, and the material of the internal viewing ports is transparent tempered glass.

[0016] Further, the monitoring component includes a monitoring member, and the monitoring member includes a lifting cylinder arranged at the top end of the extension plate. The output end of the lifting cylinder is provided with a lifting rod downward. The lifting rod passes through the extension plate and extends downward. The lifting rod is slidably connected to the sliding bearing, the lifting rod is slidably connected to the inside of the sliding cylinder, and a sealing plug which is slidably connected to the monitoring cavity is arranged at the bottom end of the lifting rod.

[0017] Further, a positioning groove is arranged on the outer side of the lifting rod, and a monitor is arranged on the outer side of the positioning groove. The monitor includes a sliding sleeve slidably connected to the outer side of the lifting rod. The sliding sleeve is detachably connected to the positioning groove on the lifting rod through a bolt, and a contact induction ring corresponding to the contact ring is arranged at the top end of the sliding sleeve.

[0018] Further, the monitoring component further includes an alarm electrically connected to the contact induction ring, and the alarm is arranged at the middle position of the top end of the extension plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] By setting up the device main body, during use, the user first connects the left end of the feeding port to the output end of the stem separator of the cigarette making machine. The separator discharges the stems into the monitoring chamber inside the box through the feeding port. Subsequently, the stems will accumulate in the monitoring chamber. The user sets the operating time interval of the lifting cylinder according to actual needs. After a unit time, the lifting cylinder drives the lifting rod to move upward, and the sealing plug moves upward, driving the stems inside to move upward, and cooperating with the filter screen to press them tightly to avoid gaps inside, resulting in deviation of the monitoring results. The user adjusts the position of the monitor on the lifting rod according to the quantitative range. When the contact induction ring cannot contact the contact ring, it indicates that a sufficient amount of stems has been collected and the stem separator is operating normally. If the contact induction ring contacts the contact ring, it indicates that not enough stems have been collected and there may be a problem with the stem separator. The alarm will sound to prompt the user to check it. Subsequently, the lifting cylinder reverses, driving the lifting rod to move downward, and the sealing plug disengages from the monitoring chamber, and the stems collected inside are discharged. Immediately afterwards, the lifting cylinder drives each component to reset, and the monitoring within the next unit time can be carried out. The present invention uses a sealing plug that can move up and down to cooperate with the filter screen to compact the stems against each other, avoiding gaps in the stem accumulation, which may cause the volume of the stems to be falsely large and affect the monitoring effect, and can effectively improve the monitoring accuracy of the device for the stem volume, effectively enhancing the practicality of the device.
