Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tobacco production technology, and in particular relates to a labeling device for grading tobacco leaves. Background Technology
[0002] my country's tobacco system classifies tobacco leaves into 42 grades based on factors such as identity, color, and maturity, each corresponding to a different purchase price. Therefore, accurate grading by grading personnel is crucial for protecting the rights of tobacco farmers and tobacco stations during the procurement process. Consequently, annual training is provided to grading personnel at each tobacco station, and their grading abilities are assessed through a grading examination. This examination primarily involves providing samples of leaf tobacco and bundled tobacco for physical grading.
[0003] The organizers need to grade the samples beforehand and hide the standard answers on paper labels (e.g., by pasting blank paper over the standard answers). Then, holes are punched in the paper labels, and twine is threaded through them to tie them to the petioles of the samples. During the exam, test takers write their answers in the blank spaces on the paper labels. After the exam, the organizers reveal the standard answers and compare them with the test takers' answers for scoring. The overall process is not complicated, but due to the large number of test takers, the sample labeling preparation before the exam is quite tedious. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a labeling device for grading tobacco leaves. This invention has a simple structure and uses a label strip to quickly wrap around and adhere to the tobacco leaf stem for labeling, making the operation very convenient.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A labeling device for grading sheet cigarettes, the device comprising a base plate, a bracket disposed on one side of the base plate for receiving the label roll, and a processing mechanism disposed on the other side of the base plate;
[0007] The label roll consists of a support cylinder and label strips wound around the outer wall of the support cylinder;
[0008] The processing mechanism includes a cutting assembly for cutting label strips and an adhesive applicator for applying adhesive to the label strips, the cutting assembly being disposed between the support and the adhesive applicator.
[0009] Preferably, the cutter assembly includes a first support rod fixed to the base plate, a first pressure rod hinged to the top of the first support rod by a pin, and a blade provided on the bottom surface of the first pressure rod at the corresponding label strip movement trajectory.
[0010] Preferably, the adhesive application assembly includes a second support rod fixed to the base plate, a second pressure rod hinged to the top of the second support rod, a retainer on the bottom surface of the second pressure rod, the retainer engaging with the rotating base of the solid adhesive, and the glue stick end of the solid adhesive being positioned corresponding to the movement trajectory of the label strip.
[0011] Preferably, the bracket includes two iron support plates, and the two support plates are respectively provided with through holes and countersunk holes at the same height. One end of the hollow shaft is closed and passes through the through hole of the support plate and cooperates with the countersunk hole of the other support plate. The other end of the shaft is connected to an adjusting airbag, and a limiting airbag for locking the inner wall of the support cylinder is provided in the middle section of the shaft.
[0012] Preferably, a groove is provided in the middle section of the shaft, and the inside of the groove is airtightly covered and sealed by an annular elastic band to form the limiting airbag. Several connecting holes are opened on the shaft at the groove to connect the limiting airbag and the adjusting airbag, and one of the adjusting airbag and the limiting airbag is in an inflated state.
[0013] Preferably, the end of the regulating airbag away from the shaft is provided with a circular top plate, and a collar is sleeved on the outer wall of the top plate. The collar is made of a magnet that can attract iron support plates.
[0014] The working process of this utility model is as follows:
[0015] Initially, the first and second pressure rods are vertical. Then, the shaft is separated from the support plate, and the label roll is threaded through the shaft. The shaft is then inserted into the support plate, ensuring its closed end aligns with the corresponding countersunk hole. The position of the label roll is adjusted so it is outside the limiting airbag. The collar is then pushed against the corresponding support plate, allowing it to adhere to the plate. During this process, the collar compresses the top plate and the adjusting airbag, pushing air from the adjusting airbag into the shaft and forcing the limiting airbag to inflate, thus effectively limiting the label roll.
[0016] Then proceed with the "labeling" operation:
[0017] Pull out the free end of the label strip (during the pulling process, the label roll will cause the shaft to rotate and quickly release the label strip, while the top plate rotates relative to the collar to prevent interference with the collar), so that the label strip passes under the first pressure bar, the second pressure bar, and the tobacco stem. The staff can write the standard answer on the free end of the label strip, and then roll up the free end of the label strip and wrap it around the tobacco stem to ensure that the standard answer cannot be seen by the examinee.
[0018] During the label wrapping process, pressing down the second lever coats the label strips with solid adhesive, ensuring they adhere and secure each other during subsequent wrapping. Finally, lifting the second lever and pressing down the first lever cuts the label strips with a blade. The label strip between the first and second levers, free of adhesive, serves as the area where examinees write their answers. Later, organizers can tear off the label strips wrapped around the tobacco leaf stems and compare them to the standard answers.
[0019] Compared with the prior art, the present invention has the following advantages: The present invention has a simple structure and uses a label strip to quickly wrap and stick the tobacco leaf stem for labeling, which is very convenient to operate. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0025] like Figure 1-4 As shown, a labeling device for grading cigarettes includes a base plate 1, a support set on one side of the base plate 1 for receiving the label roll, and a processing mechanism set on the other side of the base plate 1. The label roll consists of a support cylinder 41 and a label strip 42 wound around the outer wall of the support cylinder 41.
[0026] The bracket includes two iron support plates 21, and the two support plates 21 are respectively provided with through holes 23 and countersunk holes 22 at the same height. One end of the hollow shaft 3 is closed and passes through the through hole 23 of the support plate 21 and cooperates with the countersunk hole 22 of the other support plate 21. The other end of the shaft 3 is connected to an adjusting air bag 31. The end of the adjusting air bag 31 away from the shaft 3 is provided with a circular top plate 32. The outer wall of the top plate 32 is fitted with a collar 33, which is made of a magnet that can attract the iron support plate.
[0027] The shaft 3 has a groove 34 in the middle section. The inside of the groove 34 is airtightly covered and sealed by an annular elastic band to form a limiting airbag 36. Several connecting holes 35 are opened on the shaft at the groove 34 to connect the limiting airbag 36 and the adjusting airbag 31. The adjusting airbag 31 and the limiting airbag 36 are either in an inflated state.
[0028] The processing mechanism includes a cutting assembly for cutting label strips and an adhesive applicator for applying adhesive to the label strips. The cutting assembly is located between the support and the adhesive applicator. The cutting assembly includes a first support rod 51 fixed to the base plate. A first pressure rod 52 is hinged to the top of the first support rod 51 by a pin. A blade 53 is provided on the bottom surface of the first pressure rod 52 at the corresponding movement trajectory of the label strip 41. The adhesive applicator includes a second support rod 61 fixed to the base plate. A second pressure rod 62 is hinged to the top of the second support rod 61 by a pin. A retainer 63 is provided on the bottom surface of the second pressure rod 62. The retainer 63 is engaged with the rotating base of the solid adhesive 64. The glue stick end of the solid adhesive is positioned at the corresponding movement trajectory of the label strip (the solid adhesive is a commercially available product).
[0029] The working process of this utility model is as follows:
[0030] Initially, the first pressure rod 52 and the second pressure rod 62 are in a vertical position. Then, the shaft 3 is separated from the support plate 21, and the label roll is threaded through the shaft 3. The shaft 3 is then inserted into the support plate 21, with its closed end engaging with the corresponding countersunk hole 22. The position of the label roll is adjusted so that it is outside the limiting airbag 36. Then, the collar 33 is pushed towards the corresponding support plate 21 so that it can adhere to the support plate 21. During this process, the collar 33 compresses the top plate 32 and the adjusting airbag 31, pushing the air in the adjusting airbag 31 into the shaft 3 and forcing the limiting airbag 36 to inflate, thereby effectively limiting the label roll.
[0031] Then proceed with the "labeling" operation:
[0032] Pull out the free end of the label strip 42 (during the pulling process, the label roll will cause the shaft to rotate and quickly release the label strip, while the top plate rotates relative to the collar to prevent interference with the collar), so that the label strip 42 passes under the first pressure bar 52, the second pressure bar 62 and the tobacco stem. The staff can write the standard answer at the free end of the label strip, and then roll up the free end of the label strip and wrap it around the tobacco stem to ensure that the standard answer cannot be seen by the examinee.
[0033] During the wrapping of label strip 42, pressing down the second pressure bar 62 coats the surface of the label strip with solid glue, ensuring adhesion and fixation during subsequent wrapping. Finally, lifting the second pressure bar 62 and pressing down the first pressure bar 52 causes the blade 53 to cut the label strip. The label strip between the first pressure bar 52 and the second pressure bar 62 is free of solid glue and serves as the area for examinees to write their answers. Later, organizers can tear off the label strip 42 wrapped around the tobacco leaf stem and compare it to the standard answer.
