Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing equipment, and in particular to a uniform material distribution device and a vertical feeding type shredder. Background Technology

[0002] In the cigarette manufacturing process, the performance of the leaf-cutting machine directly affects the intrinsic quality of the tobacco and the overall production efficiency of the cigarette production line. However, leaf-cutting machines frequently experience problems such as leaf slippage, uneven leaf width, and high breakage rates, which have become a major challenge in the industry. Vertical feeding leaf-cutting machines often suffer from uneven material distribution, with the tobacco leaves positioned higher at the front and lower at the back within the feeder, resulting in uneven stress on the tobacco leaves during cutting. This leads to leaf slippage, uneven width, and excessively fine tobacco, affecting the overall yield of the tobacco. Furthermore, an excessive breakage rate not only increases raw material waste but also impacts the intrinsic quality of the cigarettes. These problems not only increase the difficulty of adjustments for operators but also severely restrict the reliability and production efficiency of the cigarette production line.

[0003] Therefore, there are still shortcomings and deficiencies in the existing technology. How to provide a uniform feeding device and a vertical feeding shredder that can make tobacco leaf cloth uniform is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a uniform material distribution device and a vertical feeding shredder, which solves the technical problems that often occur in existing vertical feeding shredders, such as uneven material distribution, tobacco leaves being higher in the front and lower in the back of the feeder, and feeding biased to one side. This results in uneven force on the tobacco leaves during the cutting process, causing phenomena such as leaf slippage, uneven width, and excessively thin tobacco shreds, which affect the whole tobacco shred yield.

[0005] To achieve the above objectives, this utility model provides a uniform material distribution device, which is installed in a vertical feeding shredder. The vertical feeding shredder includes a hopper, and the top of the hopper is provided with a discharge port. The uniform material distribution device includes:

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] This utility model provides a uniform material distribution device 1, which, through a material guiding device and a material distribution plate 12, can constrain and concentrate the falling tobacco leaves, so that the tobacco leaves can be evenly and loosely distributed.

[0033] Please refer to this as well. Figures 1 to 5 The uniform material distribution device 1 provided by this utility model is installed in a vertical feeding shredder 2. The vertical feeding shredder 2 includes a hopper 21, and the top of the hopper 21 is provided with a material discharge port. The uniform material distribution device 1 includes:

[0034] The feeding device is fixedly installed at the feeding port to guide and concentrate the falling tobacco leaves;

[0035] The material distribution plate 12 is located below the material guiding device. The material distribution plate 12 is arranged in the hopper 21 by means of the swing mechanism 13.

[0036] In use, tobacco leaves enter the hopper 21 of the vertical feeder through the feeding distribution trough, and the uniform distribution device 1 is located in the upper feeding area of ​​the hopper 21. The guiding device is fixedly installed at the top of the discharge port of the hopper 21. After the tobacco leaves enter from the discharge port, they first come into contact with the guiding device. The guiding device constrains and concentrates the falling tobacco leaves, making the initial landing point of the tobacco leaves more concentrated and controllable, and preventing the tobacco leaves from accumulating too high at the front end of the hopper 21.

[0037] A distribution plate 12 is installed directly below the feeding device. After the tobacco leaves are guided by the feeding device, they fall. The distribution plate 12 is positioned in the hopper 21 and can be oscillated back and forth by the swing mechanism 13. As the distribution plate 12 swings, the falling tobacco leaves are evenly and loosely spread across the entire cross-section of the hopper 21. The length of the distribution plate 12 can be matched with the width of the hopper 21 to ensure that it can contact all the falling tobacco leaves throughout its entire swing stroke.

[0038] By setting up a guiding device, the falling tobacco leaves can be constrained and concentrated, making the initial landing point of the tobacco leaves more concentrated and controllable, and preventing the tobacco leaves from piling up too high at the front end of the hopper 21. After being concentrated and guided by the guiding device, the tobacco leaves fall evenly and loosely. The uniform distribution of the material ensures that the density of the tobacco cake is consistent, thereby significantly reducing the rate of leaf slippage during the shredding process, ensuring the uniformity of the width of the tobacco shreds, reducing the generation of excessively fine tobacco shreds and broken shreds, and improving the overall yield of whole tobacco shreds.

[0039] In some embodiments, the swing mechanism 13 includes:

[0040] A geared motor 131 is installed on a vertical feeding shredder 2;

[0041] Crank 132, the output shaft of geared motor 131 is connected to crank 132;

[0042] One end of the crank connecting rod 133 is connected to the crank 132;

[0043] The connecting rod 134 is connected at one end to the other end of the crank connecting rod 133 and at the other end to the fabric plate 12.

[0044] Please refer to this as well. Figures 1 to 2 The geared motor 131 can be specifically installed on the side wall of the hopper 21 of the vertical feeding shredder 2. The geared motor 131 outputs rotational motion, which drives the crank 132 to rotate. One end of the crank connecting rod 133 can be hinged to the outer end of the crank 132 through a pin or the like, and the other end is hinged to the connecting rod 134. Since the crank 132 is making circular motion, it will pull and push the connecting rod 134 through the crank connecting rod 133. The other end of the connecting rod 134 is hinged to the cloth plate 12. When the connecting rod 134 makes back-and-forth reciprocating motion, it will eventually drive the cloth plate 12 to swing back and forth.

[0045] In some embodiments, an arc-shaped portion 121 is provided on one side of the fabric plate 12, and a rotating shaft is rotatably provided below the material guiding device. The arc-shaped portion 121 is fixedly connected to the rotating shaft, and the connecting rod 134 is connected to the side of the fabric plate 12 away from the arc-shaped portion 121.

[0046] Please refer to Figure 4 The rotating shaft is rotatably located inside the hopper 21, below the material guiding device. The arc-shaped portion 121 of the fabric plate 12 is fixedly connected to the rotating shaft. The rotating shaft serves as the swing fulcrum of the fabric plate 12. When the connecting rod 134 moves under the drive of the reduction motor 131 and the crank connecting rod 133, the connecting rod 134 will push the fabric plate 12 forward or pull it backward. Since the fabric plate 12 is constrained by the rotating shaft through the arc-shaped portion 121, it cannot move as a whole and can only swing back and forth around the rotating shaft under the action of pushing and pulling forces.

[0047] The connecting rod 134 is connected to the lower middle part of the fabric plate 12, that is, to the side of the fabric plate 12 away from the arc-shaped part 121. This arrangement makes it easier for the connecting rod 134 to drive the fabric plate 12 to swing back and forth.

[0048] Optionally, the lower edge of the fabric plate 12, i.e. the edge of the fabric plate 12 opposite to the arc-shaped portion 121, can be set to a smooth arc or a serrated shape to better disperse and flatten the tobacco leaves.

[0049] In some embodiments, the uniform fabric distribution device 1 provided by the present invention further includes a motor driver, which is electrically connected to a geared motor 131 and is used to adjust the oscillation frequency of the fabric plate 12.

[0050] The motor driver is electrically connected to the control device and can receive instructions from the control device (such as preset parameters based on different tobacco leaf formulas) to precisely control the output speed of the geared motor 131. The output shaft of the geared motor 131 converts the rotational motion into the reciprocating motion of the connecting rod 134 through the crank 132 and the crank connecting rod 133, ultimately driving the cloth plate 12 to oscillate at a set frequency.

[0051] With this setup, the oscillation frequency of the cloth plate 12 can be adjusted according to different tobacco leaf formulas and process requirements via a motor driver, and the adjustment is convenient.

[0052] In some embodiments, please refer to Figure 2 The crank 132 is an eccentric block. The output shaft of the geared motor 131 and the crank connecting rod 133 are connected to different positions of the eccentric block. When the geared motor 131 is working and outputting rotational motion, it drives the eccentric block to make circular motion, thereby pulling or pushing the connecting rod 134 through the crank connecting rod 133.

[0053] In some embodiments, the material guiding device is a material guiding plate 11, which includes a fixed section 111 and a material guiding section 112. The fixed section 111 is vertically arranged and fixed to the inner wall of the top of the hopper 21, and the material guiding section 112 is inclinedly arranged at the discharge port.

[0054] Please refer to Figure 3 The guide plate 11 includes a fixed section 111 and a guide section 112. The fixed section 111 is provided with multiple threaded holes. The fixed section 111 can be fixed to the inner wall of the hopper 21 in the vertical direction by bolts. The guide section 112 is inclined to the fixed section 111. The guide section 112, which is inclined to the hopper 21, is used to contact the tobacco leaves. The guide section 112 constrains and concentrates the falling tobacco leaves, making the initial landing point of the tobacco leaves more concentrated and controllable, and preventing the tobacco leaves from accumulating too high at the front end of the hopper 21.

[0055] In some embodiments, the included angle between the fixed section 111 and the guide section 112 is 150 degrees.

[0056] Please refer to Figure 3 In this embodiment, the included angle between the fixed section 111 and the guide section 112 can be set to 150 degrees, at which time the guide device has a better concentration effect on the tobacco leaves.

[0057] In some embodiments, a plurality of photoelectric switches 211 are also installed inside the hopper 21.

[0058] Please refer to Figure 1Multiple photoelectric switches 211 are installed on the side wall of the hopper 21, and are electrically connected to the control device. Some of these photoelectric switches 211 are distributed horizontally to detect whether the tobacco is evenly distributed horizontally within the hopper 21. If the distribution is very even, the photoelectric switches 211 on both the left and right sides should be simultaneously blocked or exposed by the tobacco leaves. If the left photoelectric switch 211 is always blocked by the tobacco leaves (high material level) while the right photoelectric switch 211 is always exposed (low material level), an uneven distribution with the left side higher than the right side can be detected. Other photoelectric switches 211 are distributed vertically and installed at different heights (high, medium, and low) within the hopper 21 to detect the material level.

[0059] Please refer to this as well. Figure 1 and Figure 5 In addition to the uniform material distribution device 1 disclosed in the above embodiments, this utility model also provides a vertical feeding shredder 2 including the above-mentioned uniform material distribution device 1. The vertical feeding shredder 2 also includes a conveying mechanism 22, which includes a front pusher plate 221 and a rear pusher plate 222. A feed inlet is formed between the front pusher plate 221 and the rear pusher plate 222, and the tobacco leaves enter between the front pusher plate 221 and the rear pusher plate 222 through the feed inlet.

[0060] Please refer to Figure 1 The conveying mechanism 22 is used to convey tobacco leaves. The conveying mechanism 22 also includes a front pusher plate 221 and a rear pusher plate 222. After the tobacco leaves pass through the guiding device and the spreading plate 12, they are evenly distributed. The loose tobacco leaves fall freely into the feed inlet formed between the front pusher plate 221 and the rear pusher plate 222, and then are conveyed forward.

[0061] In some embodiments, the conveying mechanism 22 further includes an upper conveying chain 223 and a lower conveying chain 224. The upper conveying chain 223 is disposed near the front pusher plate 221, and the lower conveying chain 224 is disposed near the rear pusher plate 222. The distance between the upper conveying chain 223 and the lower conveying chain 224 gradually decreases along the conveying direction.

[0062] Please refer to Figure 1 Loose tobacco leaves fall freely into the feed inlet formed between the forward pusher plate 221 and the rear pusher plate 222, and are conveyed forward to the space between the upper conveyor chain 223 and the lower conveyor chain 224. They then continue to be conveyed forward through these two chains. The distance between the upper conveyor chain 223 and the lower conveyor chain 224 gradually decreases along the conveying direction. As the tobacco leaves are conveyed forward between these chains, the loose leaves are gradually compressed into a uniformly dense and compact tobacco cake.

[0063] The vertical feeding shredder 2 is also equipped with a pushing mechanism 23 and a cutting mechanism 24. The pushing mechanism 23 is located at the front end of the conveying direction of the conveying mechanism 22. The pushing mechanism 23 can push the tobacco leaves to facilitate the forward conveying of the material. The cutting mechanism 24 is located at the end of the conveying direction of the conveying mechanism 22. The tobacco cake compressed by the upper conveying chain 223 and the lower conveying chain 224 is output from the discharge port between the upper conveying chain 223 and the lower conveying chain 224. The cutting mechanism 24 can cut the tobacco cake to obtain tobacco shreds.

[0064] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0065] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
