Description

Technical Field

[0001] This disclosure relates to the field of tobacco production technology, and in particular to a tobacco cleaning device and method for cleaning tobacco inside a tobacco box, and a tobacco box flipping system. Background Technology

[0002] Cigarette box turning machines are widely used in cigarette manufacturing production lines. Their function is to lift and turn over cigarette boxes, emptying the stored tobacco into a hopper. The tobacco in the hopper can then be transported to the production line by auxiliary equipment. Together, the turning machine and the cigarette boxes enable the cross-regional flow of tobacco, playing a vital role in industrial production.

[0003] In actual production, due to the accumulation of tobacco shreds inside the tobacco box, some shreds remain stuck to the bottom of the box after it is turned over. These shreds do not fall into the hopper but instead flow with the tobacco box to subsequent processes for cleaning. Depending on the company's process requirements, the cleaned-out tobacco shreds will be downgraded or scrapped, significantly reducing their value and resulting in waste. Summary of the Invention

[0029] A tipping mechanism, located at the top of the silo, is used to tip over the cigarette boxes to unload them into the silo; and

[0030] The tobacco cleaning device inside the tobacco box in the above embodiment has a fixed frame installed at the material inlet on the top of the hopper.

[0031] The third aspect of this disclosure provides a cleaning method based on the tobacco cleaning device inside the tobacco box described in the above embodiments, including:

[0032] When the smoke box needs to be cleaned after unloading, the first moving mechanism drives the cleaning mechanism to move to the preset horizontal position corresponding to the smoke box.

[0033] Then, the cleaning mechanism is raised to the position inside the smoke box via the lifting mechanism;

[0034] The bottom inside the smoke box is cleaned by a cleaning mechanism.

The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this disclosure.

[0056] like Figures 1 to 4 This disclosure provides a tobacco cleaning device for the inside of a tobacco box, which in some embodiments includes:

[0057] A fixed frame 1 is used to install at the material receiving port 101 on the top of the silo 10;

[0058] The cleaning mechanism 4 is used to clean the tobacco shreds at the bottom of the tobacco box 20;

[0059] The lifting mechanism 3, whose top supports the sweeping mechanism 4, is used to drive the sweeping mechanism 4 to move up and down along the first direction z; and

[0060] The first moving mechanism 2 is connected to the fixed frame 1 and is located within the area enclosed by the fixed frame 1. It is used to drive the lifting mechanism 3 and the cleaning mechanism 4 to move along the second direction x, which is perpendicular to the first direction z.

[0061] The lifting mechanism 3 and the first moving mechanism 2 are configured such that when the smoke box 20 is in the unloading state, the cleaning mechanism 4 is located outside the smoke box 20 and exposed at the receiving port 101 of the hopper 10 to realize the unloading; and when the smoke box 20 is in the cleaning state, the cleaning mechanism 4 is located inside the smoke box 20 to perform cleaning.

[0062] Specifically, such as Figure 1 As shown, the fixed frame 1 has a rectangular frame structure, including two opposing first beams 11 and two opposing second beams 12. The cleaning mechanism 4 can be a blowing mechanism or a brush mechanism, etc., used to clean the inner bottom of the tobacco box 20 after unloading when it is inside the tobacco box 20, in order to remove residual tobacco. The lifting mechanism 3 and the first moving mechanism 2 can be a screw and nut mechanism, a scissor mechanism, etc.

[0063] When it is necessary to clean the smoke box 20, the first moving mechanism 2 can drive the cleaning mechanism 4 to move to the horizontal preset position corresponding to the smoke box 20; then the lifting mechanism 3 can drive the cleaning mechanism 4 to rise to be inside the smoke box 20. This movement method can prevent the cleaning mechanism 4 from colliding with the smoke box 20; then the cleaning mechanism 4 can clean the bottom of the smoke box 20.

[0064] After cleaning is completed, the cleaning mechanism 4 is lowered to the longitudinal initial position by the lifting mechanism 3 so that the cleaning mechanism 4 is moved outside the smoke box 20; then the cleaning mechanism 4 is moved to the transverse initial position by the first moving mechanism 2 so that the receiving port 101 of the hopper 10 is exposed, waiting for the next smoke box 20 to be unloaded.

[0065] This embodiment installs a cleaning device at the receiving port 101 at the top of the hopper 10. The cleaning mechanism 4 can be raised and lowered by the lifting mechanism 3 and moved along the second direction x by the first moving mechanism 2. It can enter the inside of the tobacco box 20 to clean the inner bottom surface when cleaning is needed, and move out after cleaning to expose the receiving port 101 of the hopper 10. It does not affect the entire unloading process of the tobacco box 20. After unloading, it can be cleaned directly without removing it and keeping it in an upside-down state. The residual tobacco shreds can fall directly into the hopper 10, which can improve the utilization rate of tobacco shreds in the tobacco box, reduce material waste, and save the need to transfer the tobacco box to the later process for separate cleaning, thereby improving the overall production efficiency.

[0066] In some embodiments, such as Figure 1 As shown, the first moving mechanism 2 includes a first scissor mechanism. The two free ends of the first scissor mechanism located on the first side along the second direction x are hinged to the fixed frame 1. Specifically, they are hinged at intervals along the third direction y to the first beam 11. The two free ends of the first scissor mechanism located on the second side along the second direction x are hinged to the first mounting base 5. The lifting mechanism 3 is provided on the first mounting base 5.

[0067] This embodiment uses a first scissor mechanism, which can achieve a large-amplitude translational movement in the second direction x. It has a simple structure, good stability during movement, and is not prone to vibration or loosening. Moreover, after being retracted, it is located in the fixed frame 1 on the side away from the smoke box 20 along the second direction x, and occupies a small space, so it will not affect the normal unloading process of the smoke box 20.

[0068] In some embodiments, such as Figure 1As shown, the tobacco cleaning device inside the tobacco box also includes a first drive component 6, which is installed on the fixed frame 1. Specifically, it can be installed on the first beam 11, with the installation position located between the two free ends of the first scissor mechanism. The output end of the first drive component 6 is connected to the intersection of the two first connecting rods 21 on the first side of the first scissor mechanism, and is used to drive the extension and retraction of the first scissor mechanism. For example, the first drive component 6 can be a cylinder, a hydraulic cylinder, or an electric push rod, etc.

[0069] This embodiment can drive the first scissor mechanism to move through the first drive component 6, thereby driving the lifting mechanism 3 and the sweeping mechanism 4 to move continuously along the second direction x, so as to switch between sweeping and unloading conditions.

[0070] In some embodiments, the first driving component 6 is a dual-cylinder linkage component, which includes a first cylinder 61 and a second cylinder 62. The first cylinder 61 is configured to drive the cleaning mechanism 4 to move from an initial lateral position to a first lateral position along the second direction x, and the second cylinder 62 is configured to drive the cleaning mechanism 4 to move from the first lateral position to a second lateral position along the second direction x. The first lateral position and the second lateral position are located near the two side edges inside the smoke box 20 along the second direction x.

[0071] When cleaning is required, the first cylinder 61 extends to its limit position, at which point the cleaning mechanism 4 is located below the edge of the smoke box 20 near the first drive component 6. Then, the lifting mechanism 3 drives the cleaning mechanism 4 to rise into the smoke box 20, and then the second cylinder 62 extends, which can drive the cleaning mechanism 4 to move along the second direction x inside the smoke box 20, so as to perform comprehensive cleaning within the entire range along the second direction x inside the smoke box 20.

[0072] This embodiment designs the first drive component 6 as a dual-cylinder linkage component. When cleaning is required, the first cylinder 61 can be extended to its full stroke first, and then the second cylinder 62 can be extended. This reduces the difficulty of control and prevents the cleaning mechanism 4 from colliding with the smoke box 20 when it is raised due to insufficient control accuracy of the cylinder extension amount.

[0073] In some embodiments, such as Figure 2 As shown, the first mounting base 5 includes:

[0074] Support frame 51 has a top plate 511 and two side plates 512, the two side plates 512 being spaced apart along a third direction y. The top plate 511 is connected between the tops of the two side plates 512 and serves to support the lifting mechanism 3. The third direction y is perpendicular to the first direction z and the second direction x.

[0075] The connecting rod 52 is connected to two side plates 512 at both ends and extends along the third direction y;

[0076] In this case, the free ends of the two first connecting rods 21 on the second side of the first scissor mechanism are both hinged to the connecting rod 52.

[0077] Specifically, the first scissor mechanism is horizontally arranged, and the connecting rod 52 is provided with a mounting seat near both ends. The mounting seat is slidably arranged relative to the connecting rod 52. The ends of the two first connecting rods 21 located on the second side are hinged to the mounting seats. The ends of the two first connecting rods 21 located on the first side are hinged to the first beam 11, and the end of at least one first connecting rod 21 is slidably arranged relative to the first beam 11 along a third direction y.

[0078] This embodiment, by setting a first mounting base 5, can both install the first scissor mechanism and provide stable support for the lifting mechanism 3.

[0079] In some embodiments, such as Figure 2 As shown, the first mounting base 5 is provided with guide mechanisms between its two sides along the third direction y and the fixed frame 1, which are used to guide the first mounting base 5 to move relative to the fixed frame 1 along the third direction y, which is perpendicular to the first direction z and the second direction x.

[0080] Specifically, the guiding mechanism includes a guide seat and a guide rod. The guide seat is installed on the outside of the side plate 512 and has a guide hole. The guide rod extends along the second direction x and passes through the guide hole.

[0081] This embodiment improves the stability of movement by setting a guiding mechanism, which allows the first moving mechanism 2 to drive the first mounting base 5 to move. Furthermore, since the cleaning mechanism 4 needs to rise to a relatively high height when performing cleaning tasks, improving the stability of the bottom support movement prevents the cleaning mechanism from shaking and colliding with the smoke box 20, thus improving cleaning reliability.

[0082] In some embodiments, the lifting mechanism 3 includes a second scissor mechanism, the two free ends of the second scissor mechanism at the bottom along the first direction z are hinged to the first mounting base 5, and the two free ends of the second scissor mechanism at the top along the first direction z are hinged to the second mounting base 7, the second mounting base 7 being used to support the cleaning mechanism 4.

[0083] This embodiment uses a second scissor mechanism, which can achieve a large range of lifting and lowering movements in the first direction z. It has a simple structure, good stability during movement, and is not prone to vibration or loosening. Moreover, it occupies less space in the first direction z after retraction.

[0084] In some embodiments, the tobacco cleaning device inside the tobacco box further includes a second driving component 8, with its first end mounted on the first mounting base 5 and its second end connected to the second scissor mechanism, for driving the second scissor mechanism to extend and retract along the first direction z. For example, the second driving component 8 is a linear drive mechanism, which can be a cylinder, a hydraulic cylinder, or an electric push rod, etc.

[0085] This embodiment can automatically raise and lower the cleaning mechanism 4 through the second drive component 8, which is easy to control.

[0086] In some embodiments, two second scissor mechanisms are spaced apart along the second direction x. The two second scissor mechanisms are connected by a first crossbeam 31 at their outer hinged positions. A second crossbeam 32 connects the two second connecting rods 33 at the bottom of the two second scissor mechanisms and in the same inclination direction. The second crossbeam 32 is located below the bottom cross position. The first end of the second drive component 8 is mounted on the first mounting base 5, and its second end is hinged to the second crossbeam 32.

[0087] Specifically, two suspension plates are spaced apart on both sides below the top plate 511 along the second direction x. The bottom end of the second drive component 8 can be mounted through the two suspension plates, and the top end of the second drive component 8 is hinged to the second crossbeam 32. The second scissor mechanism is formed by at least one set of cross-hinged second links 33, and the end of at least one second link 33 at the bottom of the second scissor mechanism is movably disposed relative to the first mounting base 5 along the third direction y.

[0088] This embodiment, by setting two second scissor mechanisms, makes the lifting and lowering of the second scissor mechanisms more stable. Since the cleaning mechanism 4 needs to rise to a higher height when performing cleaning tasks, improving the stability of the bottom support movement can prevent the cleaning mechanism from shaking and colliding with the smoke box 20, thereby improving the cleaning reliability.

[0089] In some embodiments, the tobacco cleaning device inside the tobacco box further includes: a second moving mechanism 9, located on top of the lifting mechanism 3, for driving the cleaning mechanism 4 to reciprocate along a third direction y, wherein the third direction y is perpendicular to the first direction z and the second direction x.

[0090] This embodiment can further expand the cleaning area at the bottom of the smoke box 20 and improve the cleaning effect when the cleaning mechanism 4 is in a specific position along the second direction x, and then move the cleaning mechanism 4 back and forth along the third direction y through the second moving mechanism 9.

[0091] In some embodiments, such as Figure 3As shown, the second moving mechanism includes: a reversing valve 90, a first telescopic cylinder 9A and a second telescopic cylinder 9B. The first telescopic cylinder 9A and the second telescopic cylinder 9B are coaxial and arranged side by side along the third direction y. The first end of each of the first telescopic cylinder 9A and the second telescopic cylinder 9B is fixed, and their second ends are connected to the cleaning mechanism 4. The air supply pipe P can selectively supply air to the first telescopic cylinder 9A and the second telescopic cylinder 9B through the reversing valve 90.

[0092] The reversing valve 90 is connected to an air supply pipe P, a first air pipe, and a second air pipe. A throttle valve 9' can be installed on both the first and second air pipes to adjust the flow rate of the incoming gas, thereby changing the blowing force. The first and second air pipes are respectively connected to the inner cavities of the first telescopic cylinder 9A and the second telescopic cylinder 9B.

[0093] When the reversing valve 90 is switched to the first position, the gas supplied by the air supply pipe P flows through the first air pipe into the first telescopic cylinder 9A, driving the first telescopic cylinder 9A to extend. Correspondingly, the second telescopic cylinder 9B retracts, reducing its inner cavity and forcing the gas to flow out through the second air pipe, thereby realizing the forward movement of the cleaning mechanism 4. When the reversing valve 90 is switched to the second position, the gas supplied by the air supply pipe P flows through the second air pipe into the second telescopic cylinder 9B, driving the second telescopic cylinder 9B to extend. Correspondingly, the first telescopic cylinder 9A retracts, reducing its inner cavity and forcing the gas to flow out through the first air pipe, thereby realizing the reverse movement of the cleaning mechanism 4.

[0094] like Figure 2 As shown, the lifting mechanism 3 includes a second scissor mechanism, and the second mounting base 7 includes two mounting seats 71, two bases 72, a guide rod 73, and a guide seat 74. The bases 72 and guide seats 74 are respectively located at both ends of the top of the second scissor mechanism. The first end of the guide rod 73 is connected to one of the bases 72, and the second end extends outward a certain distance after passing through the guide seat 74. The second end of the guide rod 73 is connected to the other base 72. A mounting seat 71 is respectively located on each of the two bases 72. The ends of the first telescopic cylinder 9A and the second telescopic cylinder 9B, which are far apart from each other, are respectively mounted on the two mounting seats 71. This structure can both fix the first telescopic cylinder 9A and the second telescopic cylinder 9B and allow the guide seat 74 to slide along the guide rod 73, thereby realizing the lifting and lowering of the second scissor mechanism.

[0095] The two free ends of the second scissor mechanism at the bottom along the first direction z are hinged to the first mounting base 5, and the two free ends of the second scissor mechanism at the top along the first direction z are hinged to the second mounting base 7. The second mounting base 7 is used to support the cleaning mechanism 4.

[0096] This embodiment, by setting two telescopic cylinders, can realize the reciprocating movement of the cleaning mechanism 4, which can more thoroughly clean the bottom of the smoke box 20 along the third direction y, and can also realize reciprocating cleaning, thereby improving the cleaning effect.

[0097] In some embodiments, the cleaning mechanism 4 includes two independent blowing chambers 41 arranged side by side along a third direction y. The two blowing chambers 41 are respectively connected to the first telescopic cylinder 9A and the second telescopic cylinder 9B. The two blowing chambers 41 are arranged with a plurality of blowing pipes 42 at intervals along the circumference of the whole in a plane perpendicular to the first direction z. The free ends of the blowing pipes 42 are bent upwards for blowing compressed gas to the bottom of the smoke box 20.

[0098] The purge chamber 41 can be a cuboid chamber extending along the second direction x. Purge pipes 42 can be arranged on both end faces along the length of each purge chamber 41 and on the side facing away from the other purge chamber 41. The free ends of all purge pipes 42 can be enclosed to form a rectangle, allowing for more effective cleaning of the corners of the smoke box 20. The free ends of the purge pipes 42 are bent upwards, causing the gas to be blown towards the bottom surface of the smoke box 20, increasing the blowing force. For example, the end of the purge pipe 42 can be bent upwards at an angle; this structure provides both appropriate blowing force and increases the blowing stroke, achieving a wider range of purge coverage.

[0099] When the reversing valve 90 is switched to the first position, the gas supplied by the air supply pipe P flows through the first air pipe into the first telescopic cylinder 9A, driving the first telescopic cylinder 9A to extend. At the same time, the gas is ejected through the multiple blow pipes 42 connected to the blow chamber 41 corresponding to the first telescopic cylinder 9A. Correspondingly, the second telescopic cylinder 9B retracts, reducing its inner cavity and forcing the gas to flow out through the second air pipe, thereby realizing the forward movement of the cleaning mechanism 4. When the reversing valve 90 is switched to the second position, the gas supplied by the air supply pipe P flows through the second air pipe into the second telescopic cylinder 9B, driving the second telescopic cylinder 9B to extend. At the same time, the gas is ejected through the multiple blow pipes 42 connected to the blow chamber 41 corresponding to the second telescopic cylinder 9B. Correspondingly, the first telescopic cylinder 9A retracts, reducing its inner cavity and forcing the gas to flow out through the first air pipe, thereby realizing the reverse movement of the cleaning mechanism 4.

[0100] This embodiment combines the blowing function and reciprocating motion function of the cleaning mechanism 4 into one, making the control simpler, the structure more compact, and the application range wider. It can achieve automatic blowing and cleaning within the limited space of the smoke box 20.

[0101] Secondly, such as Figure 1 As shown, this disclosure provides a cigarette box flipping system, which in some embodiments includes: a hopper 10 with a receiving port 101 on its top; a flipping mechanism 30 disposed on the top of the hopper 10 for flipping the cigarette box 20 to unload the cigarette into the hopper 10; and a cigarette box internal tobacco cleaning device as described in the above embodiments, wherein a fixing frame 1 is installed at the receiving port 101 on the top of the hopper 10.

[0102] This embodiment installs a cleaning device at the receiving port 101 at the top of the hopper 10. When cleaning is required, the device can enter the inside of the tobacco box 20 to clean the inner bottom surface. After cleaning, the device can be removed to expose the receiving port 101 of the hopper 10. This does not affect the entire unloading process of the tobacco box 20. After unloading, the device can be cleaned directly while the box is upside down without being removed. This allows the residual tobacco shreds to fall directly into the hopper 10, improving the utilization rate of the tobacco shreds in the tobacco box, reducing material waste, and eliminating the need to transfer the tobacco box to a later process for separate cleaning, thereby improving overall production efficiency.

[0103] Finally, this disclosure provides a cleaning method based on the tobacco cleaning device of the above embodiments, including:

[0104] When the smoke box 20 needs to be cleaned after unloading, the first moving mechanism 2 drives the cleaning mechanism 4 to move to the preset horizontal position corresponding to the smoke box 20.

[0105] Then, the cleaning mechanism 4 is raised to be inside the smoke box 20 by the lifting mechanism 3;

[0106] The bottom of the smoke box 20 is cleaned by the cleaning mechanism 4.

[0107] The above steps are performed sequentially.

[0108] This embodiment can automatically control the cleaning mechanism 4 to reach inside the smoke box 20 when cleaning is required, through the cooperation of the first moving mechanism 2 and the lifting mechanism 3, thereby cleaning the inner bottom surface of the smoke box 20, which can improve cleaning efficiency.

[0109] In some embodiments, the tobacco cleaning device inside the tobacco box further includes a first driving component 6 for driving the first moving mechanism 2 to operate. The first driving component 6 is a dual-cylinder linkage component, which includes a first cylinder 61 and a second cylinder 62.

[0110] Before the lifting mechanism 3 is activated, the first cylinder 61 drives the sweeping mechanism 4 to move to the first lateral position.

[0111] During the cleaning process, the cleaning mechanism 4 is moved from the first lateral position to the second lateral position by the second cylinder 62. The first lateral position and the second lateral position are located near the two side edges of the smoke box 20 along the second direction x.

[0112] When cleaning is required, the first cylinder 61 extends to its limit position, at which point the cleaning mechanism 4 is located below the edge of the smoke box 20 near the first drive component 6. Then, the lifting mechanism 3 drives the cleaning mechanism 4 to rise into the smoke box 20, and then the second cylinder 62 extends, which can drive the cleaning mechanism 4 to move along the second direction x inside the smoke box 20, so as to perform comprehensive cleaning within the entire range along the second direction x inside the smoke box 20.

[0113] This embodiment designs the first drive component 6 as a dual-cylinder linkage component. When cleaning is required, the first cylinder 61 can be extended to its full stroke first, and then the second cylinder 62 can be extended. This reduces the difficulty of control and prevents the cleaning mechanism 4 from colliding with the smoke box 20 when it is raised due to insufficient control accuracy of the cylinder extension amount.

[0114] In some embodiments, the tobacco cleaning device inside the tobacco box further includes: a second moving mechanism 9, disposed at the top of the lifting mechanism 3, for driving the cleaning mechanism 4 to reciprocate along a third direction y, wherein the third direction y is perpendicular to the first direction z and the second direction x; the cleaning method further includes:

[0115] During the cleaning process, when the cleaning mechanism 4 is in a certain position along the second direction x, the second moving mechanism 9 causes the cleaning mechanism 4 to reciprocate along the third direction y.

[0116] This embodiment can further expand the cleaning area at the bottom of the smoke box 20 and improve the cleaning effect when the cleaning mechanism 4 is in a specific position along the second direction x, and then move the cleaning mechanism 4 back and forth along the third direction y through the second moving mechanism 9.

[0117] In some embodiments, the cleaning method further includes:

[0118] After cleaning is completed, the lifting mechanism 3 drives the cleaning mechanism 4 to lower to the initial longitudinal position;

[0119] Then, the first moving mechanism 2 drives the cleaning mechanism 4 to move to the initial horizontal position to expose the receiving port 101 of the hopper 10.

[0120] After cleaning is completed, the cleaning mechanism 4 is lowered to the initial longitudinal position by the lifting mechanism 3 so that the cleaning mechanism 4 is moved outside the smoke box 20; then the cleaning mechanism 4 is moved to the initial transverse position by the first moving mechanism 2 so that the receiving port 101 of the hopper 10 is exposed, waiting for the next smoke box 20 to be unloaded.

[0121] This embodiment can be removed after cleaning to expose the receiving port 101 of the hopper 10, without affecting the entire unloading process of the tobacco box 20. After unloading, it can be cleaned directly without removing it and keeping it in an upside-down state, so that the residual tobacco shreds can fall directly into the hopper 10. This can improve the utilization rate of tobacco shreds in the tobacco box, reduce material waste, and save the need to transfer the tobacco box to a later process for separate cleaning, thereby improving the overall production efficiency.

[0122] The above are merely exemplary embodiments of this disclosure and are not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
