Description

Technical Field

[0001] The present application relates to the technical field of tobacco processing equipment, and in particular to a tobacco sheet packaging device. Background Art

[0002] At present, in the primary processing of tobacco, after leaf beating and re-drying, the tobacco leaves are weighed in the pre-pressing and packaging system and then put into the packaging box. The tobacco leaves after re-drying in the tobacco industry need to be packed by the pre-pressing and packaging system. The current tobacco leaf pre-pressing and packaging system mainly adopts the traditional asynchronous motor quantitative pump hydraulic system. During the processing, the entire hydraulic system keeps running. When the hydraulic actuator needs to perform corresponding actions, the oil is transported to the actuator by adjusting the hydraulic valve to realize the pre-pressing and packaging process.

[0003] In the related art, before pre-pressing and packaging, the cigarette flakes transmitted from the upstream are first collected through the packaging box. When the cigarette flakes in the packaging box are full or the required weight is collected, the cigarette flake pre-pressing and packaging system is used for pre-pressing and packaging to form cigarette packages. In this process, there are generally industry standard requirements for the weight of a single cigarette package, for example, it needs to reach 200kg±0.25kg. Since the cigarette flakes are relatively fluffy during the loading process, in order to meet this standard, the packaging box is generally larger in size, or a smaller packaging box is used, and after multiple pre-pressing, a cigarette package that reaches the standard weight is formed.

[0004] Both of the above methods have certain disadvantages. The first pre-pressing method uses a larger packaging box, which requires a larger floor space, and the final cigarette package also changes with the shape of the packaging box. The second pre-pressing method requires a slightly smaller packaging box, but the result of multiple pre-pressing is that the overall structure of the final cigarette package is unstable and there is a risk of loose packages. Secondly, each pre-pressing requires a certain range of shutdown, which affects the packaging efficiency, and frequent shutdown operations also have a certain impact on the machine life itself.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0037] The embodiment of the present application provides a cigarette sheet packaging device, which can solve the problem in the related art that the packaging box required for pre-pressing and packaging of cigarette sheets is large in volume or requires frequent shutdown for multiple pre-pressing, which affects the quality of the cigarette packaging box, packaging efficiency and packing density.

[0038] See also Figure 1 As shown, the tobacco sheet packaging device includes a material-dividing and spreading unit 1, at least one falling and evenly spreading unit 2 and a material pressing unit 3, wherein the material-dividing and spreading unit 1 is used to evenly spread the tobacco sheets transmitted from upstream, and the falling and evenly spreading unit 2 arranged on the side of the material-dividing and spreading unit 1 receives the tobacco sheets transmitted by the material-dividing and spreading unit 1, and is used to guide the tobacco sheets to evenly fall into the packaging box 4 located therebelow. The pressing unit 3 includes a plurality of pressing pieces 31 arranged side by side at the bottom of the falling and evenly spreading unit 2. There are a first state and a second state between the plurality of pressing pieces 31. When in the first state, the plurality of pressing pieces 31 are used to assist the falling and evenly spreading unit 2 in guiding the cigarette sheets to fall evenly into the packing box 4, so as to facilitate subsequent pre-pressing and packing. When in the second state, the plurality of pressing pieces 31 are used to pre-press the cigarette sheets in the packing box 4 while loading the cigarette sheets, and can effectively compress the cigarette sheets in the packing box 4, so that the packing box 4 of the same volume can load as many cigarette sheets as possible, thereby reducing the volume of the packing box 4. In addition, the pre-pressing process does not affect the loading process, and there is no need to shut down the relevant equipment. While ensuring the quality of the cigarette packs, the packaging efficiency is greatly improved, and time and labor are saved.

[0039] For further information, see Figure 5-Figure 6As shown, the pressing unit 3 includes two groups of driving components symmetrically arranged on opposite sides of one group of the falling and evenly spreading units 2, and the two groups of driving components are configured as follows: multiple pressing pieces 31 are rotated side by side between the two groups of driving components, and both ends are respectively connected to corresponding driving components. When in a first state, the multiple pressing pieces 31 are parallel to each other to form multiple falling gaps 30, and the multiple pressing pieces 31 are used to synchronously reciprocate within a first preset angle. When in a second state, the multiple pressing pieces 31 are parallel to the horizontal direction and interlock with each other to form a pressing surface. The driving component is used to control the conversion of the multiple pressing pieces 31 between the first state and the second state, and is used to drive the multiple pressing pieces 31 to synchronously reciprocate within the first preset angle and the pressing surface to move along the vertical direction.

[0040] Specifically, a set of opposite sides of the falling and evenly paving unit 2 where the two sets of driving components are located is parallel to the transmission direction of the material-dividing and paving unit 1, and the pressing piece 31 is in the shape of a rectangular sheet. Multiple pressing pieces 31 rotate side by side and are arranged between the two sets of driving components. Under the drive of the two sets of driving components, they can be arbitrarily switched between the first state and the second state. When in the first state, multiple pressing pieces 31 are parallel to each other and synchronously reciprocate within a first preset angle, that is, when in the first state, multiple pressing pieces 31 are in a dynamic state. During the synchronous rotation process, since there is a gap between the pressing pieces 31, it will not hinder the falling of the cigarette sheets. On the contrary, the reciprocating pressing piece 31 can also allow the cigarette sheets falling thereon to fall more evenly into the packing box 4 below; when in the second state, it is necessary to pre-press the cigarette sheets in the packing box 4 at this time. Therefore, at this time, multiple pressing pieces 31 are parallel to the horizontal direction and interlock with each other to form a complete pressing surface. Then, under the drive of the two sets of driving components, it moves downward to realize the pre-pressing of the cigarette sheets during the loading process.

[0041] Furthermore, the driving assembly specifically includes a first driving member 50 and at least one second driving member 51, wherein the first driving member 50 is horizontally arranged along the inner wall of the falling and evenly spreading unit 2, and the first driving member 50 is rotatably connected to the corresponding ends of the plurality of pressing members 31 along its length, and is used to drive the pressing members 31 to rotate; at least one second driving member 51 is arranged above the first driving member 50 and arranged along the vertical direction, and the second driving member 51 is used to drive the first driving member 50 to drive the pressing surface to move in the vertical direction according to the rotation angle of the pressing member 31. Specifically, from the perspective of pre-pressure, the number of the second driving members 51 here is 3, and can be increased or decreased according to the side length of the packaging box 4 to ensure that the pressing surface is sufficiently stable and exerts sufficient pre-pressure on the tobacco leaves. When the first driving member 50 is in a horizontal state, the second driving member 51 drives the pressing surface to move in the vertical direction for pre-pressure.

[0042] Furthermore, each of the pressing pieces 31 is in the shape of an elongated strip, and a buckling groove is provided on the corresponding side of one of the pressing pieces 31 at both ends, and a buckling protrusion is provided on the corresponding side of the other pressing piece 31, and a buckling groove and a buckling protrusion are provided on both sides of the remaining pressing pieces 31, respectively, and the buckling groove and the buckling protrusion are used to buckle with each other in the second state so that the multiple pressing pieces 31 form a pressing surface. Specifically, in order to ensure that the pressing surface formed when each pressing piece 31 is in a horizontal state is sufficiently stable, a buckling groove and a buckling protrusion are provided on the pressing piece 31, and when in a horizontal state, each buckling protrusion can be pressed into the corresponding buckling groove, so that the pressing surface is as integral as possible, increasing its stability and improving the pre-pressing effect.

[0043] For further information, see Figure 2-Figure 3 As shown, the falling and evenly spreading unit 2 specifically includes a box body 20, two guide rails 21 and two guide plates 22, wherein the top and bottom ends of the box body 20 are both open ends, that is, the top end is used to receive the transmitted cigarette sheets, and the bottom end is used for the cigarette sheets to fall into the packing box 4, the two guide rails 21 are symmetrically arranged on the other set of opposite sides of the bottom of the box body 20 along the direction of the vertical driving component, the two guide plates 22 are symmetrically arranged on the two guide rails 21, and the bottom end of each guide plate 22 is slidably arranged on the two guide rails 21 in the horizontal direction, and the other end is slidably arranged on one side of the box body 20 in the vertical direction, and a material guiding channel is formed between the two guide plates 22, and the shape of the material guiding channel is adjusted by moving relative or oppositely along the two guide rails 21, thereby adjusting the uniformity of the cigarette sheets falling into the packing box 4, which is convenient for the subsequent pre-pressing and packaging.

[0044] Furthermore, each material guide plate 22 includes an inclined plate 220 and a vertical plate 221 from top to bottom. A receiving gap is dug at the connection between the inclined plate 220 and the vertical plate 221. A first roller 23 is provided in the receiving gap. A material detection photoelectric tube 27 is provided on the side of the inclined plate 220 away from the material guide channel. The first roller 23 is used to adjust its own rolling speed according to the monitoring situation of the material detection photoelectric tube 27 to avoid the cigarette sheets hanging on the material guide plate 22 or to adjust the rolling speed of the first roller 23 in time when there are too many or too few cigarette sheets to achieve the best falling state and save electricity.

[0045] Further, at least two rangefinders 24 are provided at intervals along the length direction of the vertical plate 221 on one side away from the material guide channel, and the rangefinder 24 is configured as follows: the first driving member 50 is used to drive the material pressing member 31 to rotate between the first preset angle according to the monitoring result of the rangefinder 24, so as to assist in realizing the switching between the first state and the second state, and the material guide plate 22 is used to move along the guide rail 21 according to the monitoring result of the rangefinder 24, so as to adjust the shape and moving speed of the material guide channel. Specifically, the rangefinder 24 is used to regularly monitor the height of the corresponding position of the cigarette in the packing box 4, and the first driving member 50 drives the material pressing member 31 to continue to rotate between the first preset angle by using the height difference of the cigarettes monitored twice before and after by the rangefinder 24 in the first preset time period. If the height difference is too large, it means that pre-pressing is required, and the material guide plate 22 moves along the guide rail 21 by using the height difference of the cigarettes in the packing box 4 monitored twice before and after by the rangefinder 24 in the second preset time period, wherein the second preset time period is less than the first preset time period.

[0046] Furthermore, the box body 20 is provided with step structures at corresponding positions near the top of the guide plate 22 on both sides perpendicular to the guide rail 21, and a through hole 26 is provided at the step structure, and the through hole 26 is used for the corresponding guide plate 22 to pass through, and the inner wall of the box body 20 located below the through hole 26 is provided with a supporting roller 25 along its edge. The guide plate 22 passes through the corresponding through hole 26, which can ensure that the guide plate 22 can move back and forth freely along the guide rail 21, and the supporting roller 25 ensures that the guide plate 22 moves back and forth along the guide rail 21 more smoothly.

[0047] For further information, see Figure 4 As shown, the material-dividing and spreading unit 1 specifically includes a material-dividing device 10 and a conveying device 11, wherein the material-dividing device 10 includes a plurality of second rollers 100 arranged at intervals, and each second roller 100 is provided with a reverse threaded blade 101. This structure prevents the tobacco sheets from being easily blocked during transmission, ensures that the material-dividing and spreading are uniform, and can be quickly adjusted. Furthermore, according to the detection result of the packing density of the tobacco sheets, the rotation speed, direction and spacing between adjacent reverse threaded blades 101 are adjusted in real time, thereby achieving uniform spreading of the material. The conveying device 11 includes a bidirectional conveying platform 110, which is arranged below the material-dividing device 10. Correspondingly, there are two falling and evenly spreading units 2, which are respectively located on both sides of the bidirectional conveying platform 110, so that two packing boxes 4 can be packed at the same time.

[0048] Furthermore, the cigarette packing device includes a control unit, which is connected to the first driving member 50, the second driving member 51, the first motor for controlling the movement of the guide plate 22, the second motor for controlling the rotation of the first roller 23, the rangefinder 24, the third motor for controlling the rotation of the second roller 100 and the bidirectional conveying platform 110, etc., for performing corresponding control operations.
