Description

Technical Field

[0001] The utility model belongs to the technical field of flue-cured tobacco processing, and in particular relates to an automatic thread winding device for flue-cured tobacco hanging rods. Background Art

[0002] With the development of modern agriculture and the introduction of advanced production technology, the production level of tobacco leaves in my country has been continuously improved. Fresh leaves obtained from the field need to be sent to the curing room for curing in time. Before curing, tobacco leaves must go through four links: harvesting, sorting, weaving, and loading. At present, tobacco farmers in flue-cured tobacco producing areas mostly use bamboo hanging tobacco rods and weaving tobacco lines to manually weave fresh tobacco leaves together, and then hang them in the curing room for curing. After the tobacco leaves are baked out of the oven, the whole tobacco rods that have been baked and moistened should be transported to the processing and grading room for unwinding and grading. The weaving lines after the manual unwinding need to be manually and orderly wound around the tobacco rods for reuse next time.

[0003] After the flue-cured tobacco leaves are untied from the stems, the braided tobacco thread needs to be manually wound onto the tobacco hanging stems. Manual winding is time-consuming and labor-intensive, which seriously affects the work efficiency of the post-curing grading processing. Utility Model Content

[0004] In view of the above shortcomings, the utility model provides an automatic wire winding device for a flue-cured tobacco hanging rod, which inserts the hanging rod into a V-shaped rubber bowl, and the motor drives the V-shaped rubber bowl to rotate, thereby driving the hanging rod to rotate, so as to realize the rapid winding of the braided tobacco wire on the hanging rod. A foot switch is provided to facilitate the adjustment of the motor speed, free up both hands, and improve the convenience of winding the braided tobacco wire on the hanging rod.

Semi-automatic winding of the hanging rod is realized, and the winding efficiency of the braided tobacco wire on the hanging rod is improved.

[0007] Furthermore, a threaded hole connected to the V-shaped groove is provided at the bottom of the V-shaped rubber bowl, and the connection mechanism includes a tapered block, a second coupling, and a screw connecting the tapered block and the second coupling, the screw passes through the threaded hole and cooperates with the threaded hole, the tapered block is located in the V-shaped groove, and the diameter of the tapered block is smaller than the diameter of the cigarette hanging rod, and the second coupling is connected and cooperated with the first coupling.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] It should be noted that the directional terms such as left, right, up, down, front and back in the embodiments of the present invention are merely relative concepts or are based on the normal use state of the product, that is, the direction of movement of the product, and should not be considered as limiting.

[0030] In addition, it should be noted that the dynamic terms such as "relative motion" mentioned in the embodiments of the present invention are not only changes in position, but also include movements such as rotation and rolling where there is no relative change in position but a change in state.

[0031] Finally, it should be noted that when a component is referred to as being "located" or "set on" another component, it can be on the other component or there can be an intermediate component at the same time. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or there can be an intermediate component at the same time.

[0032] like Figures 1 to 7 The automatic winding device for hanging tobacco rods shown in the figure comprises a support frame 1, a V-shaped rubber bowl 3 and a foot switch 6. A motor 2 is mounted on the support frame 1, and a first coupling 22 is arranged at the output shaft 21 of the motor 2. A V-shaped groove 31 is provided on the inner side of the V-shaped rubber bowl 3, and the V-shaped groove 31 can carry the hanging tobacco rod 4. The V-shaped rubber bowl 3 is mounted to the first coupling 22 through a connecting mechanism 5. The foot switch 6 is connected to the motor 2 through a wiring harness 61, and a stepless speed regulating mechanism is arranged in the foot switch 6. The smaller the opening and closing degree of the foot switch 6 is, the faster the speed of the V-shaped rubber bowl 3 driven by the motor 2 is, and the faster the speed of the hanging tobacco rod 4 located above the V-shaped groove 31 is. Semi-automatic winding of the hanging tobacco rod 4 is realized, and the winding efficiency of the braided tobacco wire on the hanging tobacco rod 4 is improved.

[0033] In one embodiment, the automatic winder installation process is as follows: first, the motor 2 needs to be installed on the support frame 1 to fix the motor 2. Then the V-shaped rubber cup 3 is installed to the first coupling 22 of the motor 2 through the connecting mechanism 5, that is, the V-shaped rubber cup 3 is coaxially arranged with the output shaft 21 of the motor 2. And the foot switch 6 connected to the motor 2 through the wire harness 61 is adjusted to a suitable position.

[0034] In one embodiment, when in use, the cigarette hanging rod 4 is inserted into the V-shaped groove 31 of the V-shaped rubber bowl 3, and the end of the braided cigarette line is wound and fixed to the cigarette hanging rod 4. The staff member supports the top of the cigarette hanging rod 4 with one hand, holds the braided cigarette line with the other hand, and steps on the foot switch 6. As the foot switch 6 is closed, the motor 2 drives the cigarette hanging rod 4 to rotate rapidly through the V-shaped rubber bowl 3, so that the braided cigarette line is quickly wound on the cigarette hanging rod 4. It should be noted that when the cigarette hanging rod 4 rotates rapidly, its maximum speed is still within the acceptable range for people, and when the cigarette hanging rod 4 is manually held, it basically does not cause danger to the human hand. The human hand only supports the cigarette hanging rod 4 to prevent the cigarette hanging rod 4 from tilting, and does not hold and fix the cigarette hanging rod 4.

[0035] In one embodiment, it is necessary to explain again that after the flue-cured tobacco in the current tobacco area is harvested from the tobacco field, the tobacco growers use bamboo hanging tobacco rods 4 to tie the tobacco leaves through the braided tobacco line and then hang them in the curing room. After the tobacco leaves are baked out of the oven, the whole tobacco rods that have been baked and moistened well should be transported to the processing and grading room to be untied and then graded. Generally, the farm manually unties the rods and then winds the braided tobacco line on the hanging tobacco rod 4 in an orderly manner, so that when the tobacco is tied next time, the braided tobacco line can be untied and reused. Generally, according to the daily workload, the line is wound about 80 rods a day, and the work efficiency is very low. Now is an era of labor shortage. The tobacco workers are older, and manual winding is too strenuous and labor-intensive. After adopting the automatic winding machine, the work efficiency is improved and the work intensity is reduced. According to calculations, for a 3-meter braided tobacco line, manual winding takes 30 seconds per rod, and the machine winding takes 5 seconds per rod, which is 6 times more efficient than pure manual winding. In addition, the workers also greatly save the arm strength of winding the line, and their arms are not sore.

[0036] In one embodiment, the motor 2 can be replaced by a commonly used hand drill, and the support frame 1 can be replaced by a common table, which greatly saves the production cost and difficulty of the automatic wire winder.

The V-shaped rubber bowl 3 and the connecting mechanism 5 are installed and cooperated.

[0039] Preferably, the connecting mechanism 5 also includes a locking ring 54, which is sleeved onto the outer side of the screw 53. The locking ring 54 is threadedly connected to the screw 53.

[0044] Preferably, a support leg 13 is provided at the bottom of the support frame 1, and the support leg 13 includes a support tube 131 and a telescopic leg 132 inserted into the support tube 131. The telescopic leg 132 can slide in the vertical direction relative to the support tube 131 to achieve height adjustment of the support frame 1, which is convenient for winding the braided cigarette wire onto the cigarette hanging rod 4.

[0045] In one embodiment, before using the automatic wire winder, the height of the support frame 1 can be adjusted by the support legs 13 to adjust the support frame 1 to a height suitable for the height of the people, thereby improving the comfort during wire winding.

[0050] Preferably, a second conical rubber pad 42 is sleeved on the outer side of the conical portion 41 to further increase the friction between the cigarette hanging rod 4 and the V-shaped rubber bowl 3 .
