Description

Technical Field

[0001] The utility model relates to a tobacco machine, in particular to a vertical material channel with an adjustable effective conveying length. Background Art

[0002] In the tobacco industry, the transportation process of filter rods or cigarettes usually relies on a conveying channel composed of two conveyor belts. In the horizontal, inclined and vertical directions, the rotational power of the conveyor belts forming the upper and lower walls or the left and right walls is used as the driving force to carry out the material transportation. This friction-based transmission method is particularly suitable for rod-shaped materials because the rotational motion of the rod-shaped material itself will not cause damage to the material.

[0003] In some scenarios where material lifting operations are performed vertically, the height of vertical lifting may change due to the site, application environment, etc., and there is a problem of over-design in designing transmission mechanisms of different heights for different heights, resulting in a series of subsequent management and usage problems such as diverse equipment specifications, increased management complexity, and diverse equipment specifications required for maintenance.

[0004] Therefore, it is necessary to design a vertical material channel with adjustable vertical effective conveying length to meet this demand, so that the types of objects required for subsequent management and maintenance can be greatly reduced.

[0005] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content

[0006] The purpose of the utility model is to address the deficiencies of the existing technology and thus provide a vertical material channel with an adjustable effective conveying length, the vertical length of which can be dynamically adjusted to reduce the difficulty of later management, maintenance and use.

[0007] In order to achieve the above-mentioned object, the technical solution adopted by the present utility model is: a vertical material channel with adjustable effective conveying length, comprising a first rotary belt mechanism and a second rotary belt mechanism;

[0008] The first rotary belt mechanism includes two fixed rotary wheels and a first rotary belt tensioned on the two rotary wheels. The first rotary belt mechanism is vertically arranged as a whole, and the inner side of the first rotary belt forms one of the channel walls of the vertical material channel.

[0009] The second rotary belt mechanism includes an upper rotary wheel, a lower rotary wheel, a second rotary belt, and a belt buffer unit. The upper rotary wheel and the lower rotary wheel can be adjusted in height in the vertical direction respectively. The second rotary belt is tensioned by the belt buffer unit, the upper rotary wheel, and the lower rotary wheel. The belt buffer unit is used to dynamically buffer a portion of the second rotary belt. The second rotary belt between the upper rotary wheel and the lower rotary wheel forms another channel wall of the vertical material channel.

[0010] The channel side length of the first rotary belt mechanism is more than three times the minimum effective length in the channel of the second rotary belt mechanism.

[0011] Based on the above, the upper rotary pulley of the second rotary belt mechanism is provided with an upper moving mechanism as a vertical driving power.

[0012] Based on the above, the lower rotary pulley of the second rotary belt mechanism is provided with a lower moving mechanism serving as a vertical driving power.

[0013] Based on the above, the upper moving mechanism / lower moving mechanism includes a vertically arranged linear slide, and the upper rotary wheel / lower rotary wheel is arranged at the action end of the linear slide.

[0014] Based on the above, the belt buffer unit includes two pulley frames and a spacing adjustment mechanism. Two rows of vertically distributed pulleys are respectively installed on the two pulley frames. The spacing adjustment mechanism is used to adjust the spacing between the two pulley frames. A portion of the second rotating belt is wound on the two rows of pulleys in sequence.

[0015] Based on the above, the spacing adjustment mechanism includes a telescopic cylinder, an electric cylinder or a hydraulic cylinder.

[0016] Based on the above, when the second rotating belt mechanism is in the minimum length state, the second rotating belt portion constituting another channel wall is opposite to the center area of the first rotating belt.

[0017] Compared with the existing technology, the present invention has substantial characteristics and progress. Specifically, when the present invention is applied to the transmission of vertical rod-shaped materials, it can adjust the effective length of the second rotary belt mechanism according to different scenarios and different needs, and adjust the effective length of the entire vertical material channel to meet different scenarios and needs, so that the set of equipment can adapt to the needs of a variety of different products and scenarios. In the subsequent management, maintenance and use process, the staff only needs to understand the specific work flow of a set of equipment, and it can be universally adapted to all equipment. The required accessories are also universal, especially the length of the second rotary belt is unified, which reduces the difficulty of work. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solution of the present utility model is further described in detail below through specific implementation methods.

[0021] like Figure 1 As shown, a vertical material channel with adjustable effective conveying length includes a first rotary belt mechanism and a second rotary belt mechanism.

[0022] The first rotary belt mechanism includes two fixed rotary wheels 11 and a first rotary belt 12 tensioned on the two rotary wheels. The first rotary belt mechanism is vertically arranged as a whole, and the inner side of the first rotary belt 12 forms one of the channel walls of the vertical material channel 1;

[0023] The second rotary belt mechanism includes an upper rotary pulley 21 , a lower rotary pulley 22 , a second rotary belt 23 and a belt buffer unit 24 .

[0024] The upper rotary wheel 21 and the lower rotary wheel 22 can adjust the height in the vertical direction respectively. In this embodiment, the upper rotary wheel 21 is configured with an upper moving mechanism as a vertical driving power, adopting a first linear slide 25, and the upper rotary wheel 21 is installed at the moving end of the first linear slide 25; the lower rotary wheel 22 is configured with a lower moving mechanism as a vertical driving power, adopting a second linear slide 26, and the lower rotary wheel 22 is installed at the moving end of the second linear slide 26.

[0025] The positions of the first linear slide 25 and the second linear slide 26 can be adjusted separately, or they can be adjusted synchronously and at equal intervals through a controller to meet various requirements.

[0026] The second rotating belt 23 is tensioned by the belt buffer unit 24, the upper rotating wheel 21 and the lower rotating wheel 22. The belt buffer unit is used to dynamically cache a portion of the second rotating belt. The second rotating belt 23 between the upper rotating wheel 21 and the lower rotating wheel 22 forms another channel wall of the vertical material channel 1.

[0027] In order to meet the need of adjusting the stroke, the channel side length of the first rotary belt mechanism is more than three times the minimum effective length in the channel of the second rotary belt mechanism.

[0028] Working principle description:

[0029] The overall position and height of the first rotary belt mechanism remain unchanged, and its maximum height and maximum distance are the maximum height and the longest effective transmission length of the vertical material channel under this scheme.

[0030] The specific height adjustment is completed with the help of the second rotary belt mechanism. When height adjustment is required, the specific positions of the upper rotary wheel 21 and the lower rotary wheel 22 are adjusted to match the upstream and downstream objects required to cooperate, and a continuous material conveying channel is built to meet the transmission height requirements of the upstream and downstream equipment.

[0031] Generally speaking, the upstream and downstream equipment are usually non-vertical transmission mechanisms, such as horizontal or inclined conveying channels. Therefore, a curved guide plate 27 will be added at the intersection of the upstream and downstream conveying channels and the vertical material channel of this scheme to guide the flow and realize the connection, conduction and turning of the material conveying channel.

[0032] In a preferred embodiment, the guide plate can be mounted on the first linear slide 25 and the second linear slide 26 in a manner that is synchronized with the upper rotary wheel 21 and the lower rotary wheel 22 so as to dynamically adapt to the upstream and downstream conveying channels.

[0033] Of course, there are usually side panels on the front and back sides of the material conveying channel for closing the channel, and the distance between the two side panels can be slightly greater than the length of the rod-shaped material.

[0034] In a preferred embodiment, the belt buffer unit 24 includes two pulley frames 241 and a spacing adjustment mechanism 242. Two rows of vertically distributed pulleys 243 are respectively installed on the two pulley frames 241. The spacing adjustment mechanism 242 is used to adjust the spacing between the two pulley frames 241. A portion of the second rotating belt 23 is sequentially wound on the two rows of pulleys 243. The spacing adjustment mechanism 242 includes a telescopic cylinder, an electric cylinder, or a hydraulic cylinder.

[0035] This constitutes a set of dynamic buffer units that can temporarily store most of the length of the second rotary belt 23.

[0036] In some embodiments, in order to make the length adjustment have the characteristic of extending equidistantly from the middle to both ends, when the second rotating belt mechanism is in the minimum length state, the second rotating belt portion constituting the other channel wall is opposite to the central area of the first rotating belt, and the vertical material conveying channel increases in length from the middle to both ends.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for which protection is requested in the utility model.
