Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "central," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings for convenience in describing the invention and for simplicity in description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be considered limiting of the scope of the invention.
As described above, since the inner space of the prepress is relatively closed and the falling height of the tobacco leaves is large, a large amount of tobacco fragments, hemp threads and dust are sprayed upward and accumulated on the top platform in the prepress during the falling and packing of the tobacco leaves, and thus are difficult to remove.
Therefore, the invention provides a tobacco leaf packaging prepressing system, a tobacco leaf packaging prepressing method and a tobacco leaf packaging prepressing machine, which can reduce the ejection amount of tobacco leaves in the falling process and effectively remove hemp fibers and dust.
In some embodiments of the present invention, the tobacco leaf baling prepressing system includes a tobacco box 10, a casing 20, a dust removing device 30, and an air speed adjusting device 40. Wherein, the smoke box 10 is used for collecting and storing tobacco leaves, the sleeve box 20 is arranged above the smoke box 10 and is communicated with the smoke box 10 so as to enable the tobacco leaves to fall into the smoke box 10 through the sleeve box 20, the dust removing device 30 is communicated with the sleeve box 20 and is used for removing hemp threads and dust generated in the falling process of the tobacco leaves, and the wind speed adjusting device 40 is used for adjusting the wind speed in the sleeve box 20.
The purpose of the casing 20 is to provide a path for the tobacco leaves to fall through, while facilitating the collection of the hemp thread and dust through the path. The structure of the jacket 20 can be designed according to specific work requirements, for example, the jacket can be designed into an integrated type or a split type according to requirements, the jacket can also be further divided into a movable part and a fixed part, and the inner diameters of the jacket can be selected differently to adapt to different working condition requirements.
According to the past practical experience, the tobacco leaves fall at a high height and fall in a scattered manner, so that a large amount of irregular ascending air flow is generated inside the casing 20, and the ascending air flow carries a large amount of tobacco leaves, hemp threads and dust to be sprayed to the upper part of the casing 20. The tobacco leaves, the hemp threads and the dust are finally accumulated at the top platform in the sleeve box 20, which results in great loss of the tobacco leaves on the one hand, and on the other hand, the accumulated tobacco leaves, the hemp threads and the dust fall off in the subsequent working process, which can adversely affect the purification of the tobacco leaves in the tobacco box 10.
The dust removal device 30 is arranged to remove the hemp threads and the dust in the jacket 20, the air speed adjusting device 40 is arranged to suck air formed in the falling process of a part of tobacco leaves, so that the air speed in the jacket 20 is adjusted to reduce the upward spraying amount of the tobacco leaves and the floating amount of the tobacco leaves near a dust removal opening, meanwhile, light impurities such as the hemp threads and the dust can float, and the dust removal air volume of the dust removal device 30 is further increased to remove the light impurities such as the dust and the hemp threads.
In some embodiments of the present invention, the tobacco leaf packing and prepressing system further includes a leaf laying plate 50, the leaf laying plate 50 is swingably disposed in the casing 20, and the leaf laying plate 50 includes a standby state and a working state; in the standby state, the leaf-laying plate 50 is arranged vertically; in the operating state, the leaf laying plate 50 swings back and forth toward the tobacco inlet 21 of the pocket 20 to uniformly lay the falling tobacco in the tobacco box 10.
The leaf paving plate 50 has a guiding function on the falling of the tobacco leaves, so that the position of the tobacco leaves falling behind the tobacco box 10 can be changed by adjusting the swing angle of the leaf paving plate 50, and the tobacco leaves can be uniformly distributed in the tobacco box 10 by adjusting the swing angle of the leaf paving plate in real time according to the falling condition of the tobacco leaves in the actual production process.
In some embodiments of the tobacco leaf packing prepressing system of the present invention, a first passage is formed between a first surface 51 of the blade plate 50 and an inner wall of the casing 20, a second passage is formed between a second surface 52 of the blade plate 50 opposite to the first surface 51 and the inner wall of the casing 20, the tobacco leaves are dropped toward the tobacco box 10 through the first passage, and the wind speed adjusting device 40 includes a wind suction device 41, and an inlet of the wind suction device 41 is in fluid communication with the second passage.
Because the tobacco leaves are mainly sprayed upwards through the second channel, the air suction device 41 is arranged, so that air formed in the second channel can be sucked in the falling process of the tobacco leaves, the air speed in the second channel is adjusted to be within a proper range, the quantity of the upwards-sprayed tobacco leaves is reduced, meanwhile, the fact that light impurities such as hemp threads and dust can be continuously sprayed upwards is guaranteed, and then the quantity of dust removing air of the dust removing device 30 is increased to remove the light impurities such as the hemp threads and the dust, and the loss of the tobacco leaves cannot be caused.
In some embodiments of the tobacco leaf packing and prepressing system of the present invention, the air suction device 41 includes an air suction pipe 411 and a first air door 412, and the first air door 412 is disposed on the air suction pipe 411 and is used for adjusting the on-off state of the air suction pipe 411.
The first damper 412 may be an electrically controlled automatic damper, such that the timed opening and closing of the first damper 412 may be achieved by setting electrical control parameters.
In some embodiments, air suction device 41 includes a pump in communication with air suction duct 411 for providing suction.
In other embodiments, the outlet of the air suction pipe 411 can be connected with the dust removing device 30, so that a separate pump is not needed to be arranged in the air suction device 41 for suction, and the cost can be saved; the outlet of the air suction pipe 411 can be separately arranged, so that the air suction pipe can be independently controlled.
In some embodiments of the tobacco leaf packing and prepressing system of the present invention, the wind speed adjusting device 40 further comprises an air suction cover 42, a framework 43 and a cloth bag 44, the air suction cover 42 is disposed between the air suction pipe 411 and the sleeve box 20, the cloth bag 44 is sleeved on the periphery of the framework 43, and the framework 43 is mounted between the air suction cover 42 and the sleeve box 20.
In practice, it has been found that a filter member is provided in the suction device 41 in order to prevent the tobacco leaves from being sucked by the suction device 41 during the dropping of the tobacco leaves. The inventors have made extensive studies and have found that if a filter element in the form of a sieve is used, tobacco fragments are very easily sucked away and the sieve is quickly clogged. After a number of trials, the inventors therefore decided to use the design of the cloth bag 44. The pores of the cloth bag 44 are much smaller than those of a filter screen, and the filtering speed is low, so that tobacco fragments are not easy to adsorb, and meanwhile, the ventilation area is large enough to allow airflow to pass smoothly; meanwhile, in order to suck away part of dust, the pores of the cloth bag 44 are larger than those of a common dust removal cloth bag, so that smaller dust can be sucked away through the cloth bag 44, and the dust amount in the sleeve 20 is further reduced.
In the embodiment of the present invention, the cloth bag 44 is sleeved on the periphery of the framework 43, that is, the cloth bag 44 is wrapped on both sides of the framework 43, so that the wind sucked from the second channel by the wind speed adjusting device 40 will sequentially pass through both surfaces of the cloth bag 44, and a better tobacco leaf filtering effect can be achieved.
In some embodiments of the tobacco leaf packing and prepressing system of the present invention, the wind speed adjusting device 40 further comprises a flow guiding member 45, the flow guiding member 45 is disposed between the air suction hood 42 and the casing 20, and the bottom of the flow guiding member 45 is disposed obliquely with respect to a horizontal plane, so that the tobacco leaves adsorbed on the cloth bag 44 slide down into the casing 20.
By arranging the bottom of the flow guide piece 45 to be inclined relative to the horizontal plane, tobacco leaves falling from the cloth bag 44 can naturally slide down under the action of gravity to enter the sleeve box 20, and the tobacco leaves are prevented from being accumulated at the inlet of the air suction device 41 to influence the air suction effect of the air suction device 41.
In some embodiments of the tobacco leaf packing and prepressing system of the present invention, the cloth bag 44 is disposed obliquely with respect to the vertical plane, so that the tobacco leaves adsorbed on the cloth bag 44 are easy to fall off, thereby preventing the air permeability of the cloth bag 44 from being affected by too much adsorbed tobacco leaves.
In some embodiments of the tobacco bale prepressing system of the present invention, the air speed adjusting device 40 further comprises a puffing device 46, and the puffing device 46 is configured to be intermittently turned on during dropping of the tobacco and to blow off the tobacco adsorbed to the cloth bag 44 when turned on.
By arranging the blowing device 46, the tobacco leaves adsorbed on the cloth bag 44 can be blown down when the blowing device 46 is turned on, and the tobacco leaves are prevented from blocking the ventilation holes in the cloth bag 44. Because the flow direction of the air flow ejected by the blowing device 46 is just opposite to the flow direction of the air flow sucked by the wind speed adjusting device 40, the blowing device 46 is set to be opened intermittently, and the influence of the wind speed adjusting device 40 on the adjustment effect of the wind speed in the second channel due to the fact that the blowing device 46 is always in the opened state can be avoided. By arranging the blowing device 46, the frequency of cleaning and replacing the cloth bag 44 can be effectively reduced.
In some embodiments of the tobacco bale prepressing system of the present invention, the puffer device 46 is configured to remain open after the end of the tobacco fall and to close after a preset time has elapsed.
The blowing device 46 is kept open and is closed after the preset time, so that the dust removal air volume of the dust removal device 30 in the period can be effectively increased, and hemp threads and dust can be removed more thoroughly.
In some embodiments of the tobacco leaf baling prepressing system of the present invention, the air suction device 41 further includes a second air door 413, and the second air door 413 is configured to adjust an air volume of the air suction pipe 411.
Through setting up second air door 413, can carry out further regulation to the amount of wind that induced drafts according to actual need, avoid the amount of wind that induced drafts too big or too little and influence the effect of induced drafting.
In some embodiments of the invention, the tobacco bale prepressing machine comprises the tobacco bale prepressing system described above.
In some embodiments of the invention, the tobacco leaf baling prepressing method based on the tobacco leaf baling prepressing system includes: allowing the tobacco leaves to fall through the casing 20 into the tobacco box 10; tobacco leaves are collected and stored through the smoke box 10; the wind speed in the casing 20 is first adjusted by the wind speed adjusting device 40 so that the hemp threads and dust generated during the dropping of the tobacco leaves float to a predetermined position where they are easily sucked by the dust removing device, and then the hemp threads and dust are removed by the dust removing device 30.
The following describes a specific embodiment of the tobacco leaf baling prepressing system provided by the present invention with reference to the accompanying drawings.
As shown in fig. 1, in the preferred embodiment of the present invention, the tobacco leaf baling prepressing system includes a tobacco box 10, a casing 20, a dust removing device 30, an air speed adjusting device 40, and a leaf laying plate 50.
The tobacco box 10 is used for collecting and storing tobacco leaves, the sleeve box 20 is arranged above the tobacco box 10 and communicated with the tobacco box 10, the dust removal device 30 is communicated with the sleeve box 20, one end of the air speed adjusting device 40 is communicated with the side wall of the sleeve box 20, and the leaf paving plate 50 is arranged in the sleeve box 20 in a swinging mode.
During operation of the bale press, tobacco leaves enter the casing 20 through the tobacco leaf inlet 21 of the casing 20 and fall through the casing 20 into the tobacco box 10. A first channel is formed between the first surface 51 of the leaf laying plate 50 and the inner wall of the casing 20 through which tobacco leaves fall into the tobacco box 10, and a second channel is formed between the second surface 52 of the leaf laying plate 50 and the inner wall of the casing 20.
Since the tobacco leaves fall at a high height and fall in a loose state, and the leaf paving plate 50 swings back and forth during the falling of the tobacco leaves, a large amount of irregular ascending air flow (shown as an air flow line in fig. 1) is generated inside the casing 20, and the ascending air flow carries a large amount of tobacco leaves, hemp threads and dust to be sprayed to the upper part of the casing 20. The tobacco leaves, the hemp threads and the dust are finally accumulated at the top platform in the sleeve box 20, which results in great loss of the tobacco leaves on the one hand, and on the other hand, the accumulated tobacco leaves, the hemp threads and the dust fall off in the subsequent working process, which can adversely affect the purification of the tobacco leaves in the tobacco box 10.
The embodiment of the present invention can effectively solve the above problems by providing the dust removing device 30 at the top of the jacket 20 and the wind speed adjusting device 40 on the sidewall of the jacket 20 opposite to the second surface 52 of the louver 50.
The main function of the dust removing device 30 is to remove hemp threads and dust in the sleeve box, and the main function of the air speed adjusting device 40 is to suck air formed in the second channel in the falling process of a part of tobacco leaves, so that the air speed at the gap between the second surface 52 of the leaf paving plate 50 and the side wall of the sleeve box 20 is reduced, the upward spraying amount of the tobacco leaves is further reduced, the accumulation of the tobacco leaves on the top of the sleeve box is reduced, and meanwhile, the amount of the tobacco leaves sucked away by the dust removing device 30 is greatly reduced.

The air suction device 41 includes an air suction pipe 411, a first damper 412 and a second damper 413, and the first damper 412 and the second damper 413 are both disposed on the air suction pipe 411.
The outlet of the air suction pipe 411 may be connected to the dust removing device 30, or may be separately provided, as long as it can smoothly suck out the air in the casing 20.
In the falling process of the tobacco leaves, the first air door 412 is opened, the air suction pipe 411 is communicated with the second channel fluid, the air suction device 41 starts to suck air, and the size of the air suction volume can be adjusted through the second air door 413, so that the upward blowing air speed at the top of the casing 20 is adjusted to be lower than the suspension air speed of the tobacco leaf fragments and higher than the suspension air speed of the hemp threads and the dust in a proper range, namely, the final air speed is slightly smaller than the air speed of the top platform which is not blown up to the inside of the casing 20 by just most of the tobacco leaf fragments. After such adjustment, the upward spraying of the tobacco fragments can be minimized, and simultaneously the hemp threads and dust can be blown to the top of the casing 20, so that the hemp threads and dust can be sucked away by the dust removing device 30.
As shown in fig. 2 and 3, the wind speed adjusting device 40 further includes an air suction cover 42, a framework 43 and a cloth bag 44, the air suction cover 42 is disposed between the air suction pipe 411 and the jacket 20, the cloth bag 44 is sleeved on the periphery of the framework 43, and the framework 43 is disposed between the air suction cover 42 and the jacket 20.
In order to prevent the tobacco leaves from being adsorbed on the cloth bag 44 to affect the ventilation performance thereof, the cloth bag 44 is inclined with respect to the vertical plane so that the adsorbed tobacco leaves are easily dropped. A blowing device 46 is also provided, the blowing device 46 being mounted in the mounting chamber 47, the blowing device 46 comprising a blowing tube 461 and a blowing valve 462. In the dropping process of the tobacco leaves, the blowing device 46 is intermittently opened, so that the tobacco leaves adsorbed to the cloth bag 44 can be further blown off when the blowing device 46 is opened.
The installation chamber 47 is provided with an openable and closable door to facilitate maintenance of the cloth bag 44 and the blowing device 46.
In addition, a flow guide member 45 is further disposed at a connection position of the wind speed adjusting device 40 and the casing 20, and the bottom of the flow guide member 45 is inclined with respect to a horizontal plane, so that the tobacco leaves adsorbed to the cloth bag 44 easily slide into the casing 20 after falling.
After the tobacco leaves fall, the first damper 412 is closed, and the blowing device 46 is kept open and closed after a predetermined time. The blowing device 46 is kept open for a while, and the dust removal air volume in the dust removal device 30 is increased, so that the removal effect of hemp threads and dust inside the casing 20 can be enhanced.
Through the description of the embodiment of the tobacco leaf packing and prepressing system, it can be seen that the tobacco leaf packing and prepressing system at least has the following advantages: the waste of tobacco leaves in the packing and prepressing process can be effectively reduced, and the method plays an important role in improving the production efficiency and economic benefits; the hemp thread and dust in the packing and prepressing process can be effectively removed, and the method has important significance for improving the quality of the final tobacco leaves.
