[0055] Examples, such as Figures 1-8 As shown, a horizontal pre-pressing and packing device for producing tobacco strips is used to pre-press and pack tobacco strips into boxes. The device includes a belt pressing mechanism 10, a first conveyor belt 20, a cutting mechanism 30, a second conveyor belt 40, a stacking mechanism 50, an alignment mechanism 60, a boxing mechanism 70, and a box turning mechanism 80, wherein:

[0056] The belt pressing mechanism 10 comprises an upper pressing conveyor belt 11 and a lower pressing conveyor belt 12 which rotate in opposite directions, and the distance between the feeding ends of the upper pressing conveyor belt 11 and the lower pressing conveyor belt 12 is greater than the distance between the discharging ends, so that the loosely stacked tobacco sheets can be continuously compressed, formed and discharged.

[0057] The first conveyor belt 20 is disposed in the transverse direction between the belt pressing mechanism 10 and the palletizing mechanism 50 , and is used to convey the cut cigarette blocks to the palletizing mechanism 50 one by one.

[0058] The cutting mechanism 30 is arranged at the feeding end of the first conveyor belt 20, and the cutting mechanism 30 includes a lifting cutter 31 that can move synchronously with the first conveyor belt 20 to cut the compressed tobacco output by the belt pressing mechanism 10 into tobacco blocks of preset length.

[0059] The second conveyor belt 40 is disposed between the palletizing mechanism 50 and the carton turning mechanism 80 , and the second conveyor belt 40 can intermittently convey cigarette packs and cartons 77 to the carton turning mechanism 80 .

[0060] The stacking mechanism 50 is disposed between the unloading end of the first conveyor belt 20 and the loading end of the second conveyor belt 40 , and is used to receive the cigarette blocks conveyed by the first conveyor belt 20 and stack them on the loading end of the second conveyor belt 40 .

[0061] The alignment mechanism 60 has an alignment station and an avoidance station, the alignment station is arranged on the second conveying belt 40, the avoidance station is arranged on one side of the second conveying belt 40, and the alignment mechanism 60 can reciprocate between the alignment station and the avoidance station, and is used for stacking the tobacco blocks on the second conveying belt 40 into a tobacco stack.

[0062] The boxing mechanism 70 has a boxing station and a boxing station, the boxing station is arranged on the second conveying belt 40, the boxing station is arranged on the other side of the second conveying belt 40, and the boxing mechanism 70 can reciprocate between the boxing station and the boxing station, and is used for opening the paper box 77 downwardly on the outside of the tobacco stack.

[0063] The turning mechanism 80 is arranged at the discharging end of the second conveying belt 40, and the turning mechanism 80 can clamp the paper box 77 up and down and output the paper box 77 after being turned over by 180°.

[0064] The application adopts a horizontal structure, and the belt pressing mechanism 10, the first conveying belt 20, the cutting mechanism 30, the second conveying belt 40, the stacking mechanism 50 and the turning mechanism 80 are arranged horizontally along the material conveying direction, and the alignment mechanism 60 and the boxing mechanism 70 are arranged on both sides of the second conveying belt 40, the tobacco blocks on the second conveying belt 40 are sequentially subjected to the stacking and boxing operations by the alignment mechanism 60 and the boxing mechanism 70, which not only can greatly reduce the height of the pre-pressing and boxing device, but also can realize the automatic pre-pressing and boxing of the tobacco strips; the loose tobacco strips in the material bin 15 are continuously compressed by the obliquely arranged upper pressing conveying belt 11 and lower pressing conveying belt 12, and the periodic pushing of the tobacco strips in the material bin 15 by the pushing plate 13, which can improve the uniformity of the tobacco strip density, improve the tobacco aging effect, reduce the production operation cost, improve the leaf threshing and redrying equipment technical level and save raw materials.

[0065] In a specific embodiment, as shown in Figure 1 , Figure 2 The belt pressing mechanism 10 includes the upper pressing conveying belt 11, the lower pressing conveying belt 12, the pushing plate 13 and the bin plate 14; the number of the bin plate 14 is two, the two bin plates 14 are arranged in parallel in front of and behind each other, and the bottom plate 16 is fixedly connected to the bottom of the two bin plates 14, and the material bin 15 is surrounded between the two bin plates 14 and the bottom plate 16.

[0066] The upper pressing conveying belt 11, the lower pressing conveying belt 12 and the pushing plate 13 are arranged in the material bin 15, the upper pressing conveying belt 11 is arranged directly above the lower pressing conveying belt 12, and the upper pressing conveying belt 11 is arranged obliquely downward, and the lower pressing conveying belt 12 is arranged obliquely upward, so that the distance between the feeding ends of the upper pressing conveying belt 11 and the lower pressing conveying belt 12 is greater than the distance between the discharging ends, that is, the distance between the left ends of the upper pressing conveying belt 11 and the lower pressing conveying belt 12 is greater than the distance between the right ends.

[0067] The push plate 13 is arranged in the vertical direction just above the feeding end of the lower pressing conveyor belt 12, that is, the push plate 13 is arranged in the vertical direction just above the left end of the lower pressing conveyor belt 12, and the top end of the push plate 13 is rotatably connected to the bin plate 14, and the bottom end of the push plate 13 can swing periodically to push the material; the length of the upper pressing conveyor belt 11 is smaller than the length of the lower pressing conveyor belt 12, so that the feed port of the silo 15 is formed between the push plate 13 and the feeding end of the upper pressing conveyor belt 11, that is, the feed port of the silo 15 is formed between the push plate 13 and the left end of the upper pressing conveyor belt 11.

[0068] The periodic swinging of the bottom end of the pusher plate 13 around the top end is a prior art and will not be described in detail here.

[0069] Specifically, such as Figure 2 As shown, the upper pressing conveyor belt 11 includes an upper driving roller 111, an upper driven roller 112 and an upper compacting belt 113, and the lower pressing conveyor belt 12 includes a lower driving roller 121, a lower driven roller 122 and a lower compacting belt 123; wherein, the upper driving roller 111 and the lower driving roller 121 are arranged one above and one below at the discharge port of the silo 15, the lower driven roller 122 is arranged directly below the feed port of the silo 15, the upper driven roller 112 is arranged on one side of the feed port of the silo 15, and the upper driven roller 112 is located above the lower driven roller 122; the upper compacting belt 113 is transmission-connected between the upper driving roller 111 and the upper driven roller 112, and the lower compacting belt 123 is transmission-connected between the lower driving roller 121 and the lower driven roller 122.

[0070] This arrangement is because: after the tobacco leaves fall into the silo 15 from the feed port, they are stacked relatively loosely on the lower pressing conveyor belt 12. Since the upper pressing conveyor belt 11 rotates counterclockwise and the lower pressing conveyor belt 12 rotates clockwise, combined with the periodic pushing effect of the push plate 13 on the tobacco leaves, the tobacco leaves in the silo 15 are compressed while moving toward the discharge port of the silo 15 until they are compressed into shape and output.

[0071] In a specific embodiment, if Figure 1 、 Figure 3As shown, the cutting mechanism 30 includes a lifting cutter 31, a transverse moving mechanism 32, a cutter lifting mechanism 33 and a longitudinal mounting plate 34; wherein, the transverse moving mechanism 32 is arranged parallel to and directly above the first conveyor belt 20, and the longitudinal mounting plate 34 is arranged between the transverse moving mechanism 32 and the discharge port of the belt pressing mechanism 10, and the moving end of the transverse moving mechanism 32 is fixedly connected to the longitudinal mounting plate 34, and the transverse moving mechanism 32 is used to drive the longitudinal mounting plate 34 to move back and forth transversely; the cutter lifting mechanism 33 is arranged between the longitudinal mounting plate 34 and the discharge port of the belt pressing mechanism 10, and the fixed end of the cutter lifting mechanism 33 is fixedly connected to the longitudinal mounting plate 34, and the moving end of the cutter lifting mechanism 33 is fixedly connected to the lifting cutter 31, so as to drive the lifting cutter 31 to rise or fall through the cutter lifting mechanism 33, thereby cutting the continuous tobacco blocks output by the belt pressing mechanism 10 into tobacco blocks of required length.

[0072] This arrangement is because, after the continuous tobacco block is delivered from the belt-type pressing mechanism 10 to the first conveyor belt 20, it moves forward synchronously with the first conveyor belt 20. In this embodiment, the transverse movement mechanism 32 drives the longitudinal mounting plate 34, driving the cutter lifting mechanism 33 and the lifting cutter 31 to move horizontally synchronously with the continuous tobacco block. This ensures that when the lifting cutter 31 cuts the continuous tobacco block downward, the tobacco block is cut smoothly and a rectangular tobacco block of a specific length is obtained.

[0073] Preferably, the transverse moving mechanism 32 and the cutter lifting mechanism 33 can be cylinders.

[0074] In a specific embodiment, if Figure 1 、 Figure 4 As shown, the palletizing mechanism 50 includes an upper fixed frame 51, a left support plate 52, a right support plate 53, a lower conveyor belt 54, a support beam 55, a linear telescopic mechanism 56 and a linear lifting mechanism 57; wherein, the upper fixed frame 51 is a rectangular frame, and the lower conveyor belt 54 is arranged directly below the upper fixed frame 51, and the number of the linear lifting mechanisms 57 is four, and the four linear lifting mechanisms 57 are connected between the upper fixed frame 51 and the four corners of the lower conveyor belt 54 to drive the lower conveyor belt 54 to rise or fall through the linear lifting mechanism 57.

[0075] The left and right supporting plates 52 and 53 are arranged in parallel between the upper fixed frame 51 and the lower conveying belt 54, and are used to receive and support the tobacco blocks conveyed by the first conveying belt 20. The supporting beam 55 is arranged in parallel above the lower conveying belt 54, and the two ends of the supporting beam 55 are fixedly connected with the upper fixed frame 51. The vertical plates 58 are vertically connected with the ends of the left and right supporting plates 52 and 53 away from each other. The middle part of the linear extension and contraction mechanism 56 is fixedly connected with the supporting beam 55, and the two ends of the linear extension and contraction mechanism 56 are fixedly connected with the two vertical plates 58 correspondingly, so as to drive the left and right supporting plates 52 and 53 to move reversely through the linear extension and contraction mechanism 56, and thus the tobacco blocks on the left and right supporting plates 52 and 53 fall onto the lower conveying belt 54 under the action of gravity.

[0076] Preferably, the linear extension and contraction mechanism 56 and the linear lifting mechanism 57 are both motor-driven lead screws.

[0077] In a specific embodiment, as shown in Figure 1 , Figure 5 The alignment mechanism 60 includes a first fixed frame 61, a first lifting frame 62, a first Z-direction lifting mechanism 63, an X-direction extension and contraction component 64, an X-direction pressing plate 65, a Y-direction extension and contraction component 66, a Y-direction pressing plate 67, a Z-direction extension and contraction component 68, and a Z-direction pressing plate 69. The first fixed frame 61 is a planar frame, and the first lifting frame 62 is a three-dimensional frame. The first lifting frame 62 is arranged below the first fixed frame 61 in a lifting manner. The first Z-direction lifting mechanism 63 is connected between the first fixed frame 61 and the first lifting frame 62, that is, the fixed end of the first Z-direction lifting mechanism 63 is fixedly connected with the middle part of the first fixed frame 61, and the lifting end of the first Z-direction lifting mechanism 63 is fixedly connected with the middle part of the first lifting frame 62, so as to drive the first lifting frame 62 to ascend or descend through the first Z-direction lifting mechanism 63.

[0078] One Z-direction pressing plate 69, two X-direction pressing plates 65, and two Y-direction pressing plates 67 are arranged on the inner side of the first lifting frame 62. The Z-direction pressing plate 69 is horizontally arranged at the top of the inner cavity of the first lifting frame 62. The Z-direction extension and contraction component 68 is connected between the first lifting frame 62 and the Z-direction pressing plate 69, so as to drive the Z-direction pressing plate 69 to ascend or descend through the Z-direction extension and contraction component 68. The two X-direction pressing plates 65 are arranged in parallel at the two ends of the horizontal direction of the inner cavity of the first lifting frame 62. The two X-direction extension and contraction components 64 are correspondingly connected between the first lifting frame 62 and the X-direction pressing plates 65, so as to drive the two X-direction pressing plates 65 to move reversely. The two Y-direction extension and contraction components 66 are arranged in parallel at the two ends of the vertical direction of the inner cavity of the first lifting frame 62. The two Y-direction extension and contraction components 66 are correspondingly connected between the first lifting frame 62 and the Y-direction pressing plates 67, so as to drive the two Y-direction pressing plates 67 to move reversely.

[0079] The reason is that the stacking mechanism 50 can only stack the tobacco blocks regularly on the second conveying belt 40, but the flatness of the tobacco block stack does not meet the cartoning requirements. In the embodiment, when the tobacco stack on the second conveying belt 40 moves to the alignment station, the second conveying belt 40 stops moving, the alignment mechanism 60 moves longitudinally from the avoiding station to the alignment station, and the first Z-direction lifting mechanism 63 drives the first lifting frame 62 to descend to the outside of the tobacco stack, and then the X-direction telescopic piece 64, the Y-direction telescopic piece 66 and the Z-direction telescopic piece 68 are extended to drive the X-direction pressing plate 65, the Y-direction pressing plate 67 and the Z-direction pressing plate 69 to extrude the tobacco stack, so as to stack the tobacco stack into a neat tobacco stack.

[0080] Preferably, the first Z-direction lifting mechanism 63, the X-direction telescopic piece 64, the Y-direction telescopic piece 66 and the Z-direction telescopic piece 68 are all air cylinders.

[0081] In a specific embodiment, as shown in Figure 1 、 Figure 6 、 Figure 7 The cartoning mechanism 70 includes a second fixed frame 71, a second lifting frame 72, a second Z-direction lifting mechanism 73, a telescopic clamping piece 74, a sleeve box 75 and a movable flip claw 76. The sleeve box 75 is fixedly arranged at the sleeve box station, and movable flip claws 76 are arranged on the four sides of the sleeve box 75 to cooperate with the end plates 78 of the carton 77. The end plates 78 of the carton 77 are flipped up by the cooperation of the movable flip claws 76 and the end plates 78.

[0082] The second fixed frame 71 is a planar frame, and the second lifting frame 72 is a three-dimensional frame. The second lifting frame 72 is arranged below the second fixed frame 71 and can be lifted and lowered. Guide columns 79 are arranged at the four corners of the second lifting frame 72 and the second fixed frame 71. The second Z-direction lifting mechanism 73 is connected between the second fixed frame 71 and the second lifting frame 72. That is, the fixed end of the second Z-direction lifting mechanism 73 is fixedly connected to the middle of the second fixed frame 71, and the lifting end of the second Z-direction lifting mechanism 73 is fixedly connected to the middle of the second lifting frame 72. The second Z-direction lifting mechanism 73 drives the second lifting frame 72 to rise or fall.

[0083] The number of telescopic clamping pieces 74 is at least four, and the plurality of telescopic clamping pieces 74 are fixedly arranged around the bottom of the second lifting frame 72 in the horizontal direction to clamp or release the four end plates 78 of the carton 77.

[0084] The reason is that: after the paper box 77 is manually opened downwardly and sleeved on the top of the sleeve box 75 at the sleeve box station, the four sealing plates 78 of the paper box 77 are upwardly buckled under the action of the movable claw 76; when the boxing mechanism 70 moves longitudinally from the sleeve box station to the boxing station, the paper box 77 can be sleeved on the outer side of the tobacco stack through the second Z-direction lifting mechanism 73.

[0085] Preferably, the second Z-direction lifting mechanism 73 and the telescopic clamping piece 74 can be air cylinders.

[0086] In a specific embodiment, as shown in Figure 1 , Figure 8 The turning box mechanism 80 is arranged between the second conveying belt 40 and the third conveying belt 90, and the turning box mechanism 80 comprises a turning support 81, an upper clamping conveying belt 82 and a lower clamping conveying belt 83; the upper clamping conveying belt 82 and the lower clamping conveying belt 83 are arranged in parallel, the turning support 81 is connected between the upper clamping conveying belt 82 and the lower clamping conveying belt 83, and the turning support 81 can turn the upper clamping conveying belt 82 and the lower clamping conveying belt 83 by 180° in the vertical plane, and the spacing of the upper clamping conveying belt 82 and the lower clamping conveying belt 83 can be adjusted, so that the paper box 77 conveyed on the second conveying belt 40 is turned by 180° and then conveyed to the third conveying belt 90 after the lower clamping conveying belt 83 is loosened.

[0087] The reason is that: the paper box 77 is opened downwardly on the second conveying belt 40, and needs to be opened upwardly on the third conveying belt 90. In the embodiment, after the second conveying belt 40 conveys the paper box 77 between the upper clamping conveying belt 82 and the lower clamping conveying belt 83, the upper clamping conveying belt 82 moves downwardly to clamp the paper box 77 with the lower clamping conveying belt 83, and the upper clamping conveying belt 82 and the lower clamping conveying belt 83 are driven to turn by 180° by the turning support 81, then the lower clamping conveying belt 83 on the upper side moves upwardly to loosen the paper box 77, and the upper clamping conveying belt 82 on the lower side conveys the paper box 77 opened upwardly to the third conveying belt 90.

[0088] It should be noted that the specific structure of the turning support 81 and the lifting of the upper clamping conveying belt 82 and the lower clamping conveying belt 83 are prior art, which will not be described here.

[0089] In a specific embodiment, the alignment mechanism 60 and the boxing mechanism 70 are symmetrically arranged on the two sides of the second conveying belt 40 in the longitudinal direction, the alignment station of the alignment mechanism 60 and the boxing station of the boxing mechanism 70 are coincident, and the alignment station of the alignment mechanism 60 and the sleeve box station of the boxing mechanism 70 are symmetrically arranged on the two sides of the second conveying belt 40, so that the alignment mechanism 60 can accurately sleeve the paper box 77 on the tobacco stack on the second conveying belt 40 after the tobacco stack is stacked on the second conveying belt 40.

[0090] The use process of the tooling of the present application is as follows:

[0091] The cut tobacco pieces ready to be pressed into cartons 77 enter the hopper 15 along the feeding direction, and the push plate 13 reciprocates periodically at a specific frequency to push the cut tobacco pieces forward. The upper pressing belt 113 moves along the counterclockwise direction under the drive of the upper drive roller 111, and the lower pressing belt 123 moves along the clockwise direction under the drive of the lower drive roller 121. The loose cut tobacco pieces are continuously compressed along the discharging direction under the extrusion of the upper pressing belt 113 and the lower pressing belt 123. By the time of discharging, the cut tobacco pieces have become compacted tobacco pieces of fixed width and thickness, and are moved to the first conveying belt 20.

[0092] When the compacted tobacco pieces move forward on the first conveying belt 20 by a specific length, the cutter lifting mechanism 33 drives the lifting cutter 31 to move downward to cut the continuously extruded compacted tobacco pieces. During this period, the transverse moving mechanism 32 drives the lifting cutter 31 to move forward synchronously with the first conveying belt 20, that is, the transverse moving speed of the lifting cutter 31 is consistent with the belt speed of the first conveying belt 20. Then, the cutter lifting mechanism 33 and the transverse moving mechanism 32 are reversely moved in sequence to drive the lifting cutter 31 to return to the initial position.

[0093] When the cut tobacco pieces are conveyed to the feeding and stacking mechanism 50, the linear extension mechanism 56 is actuated to drive the left supporting plate 52 to move leftward, and simultaneously drive the right supporting plate 53 to move rightward. The tobacco pieces naturally fall onto the lower conveying belt 54 under the action of gravity. Subsequently, the linear lifting mechanism 57 drives the lower conveying belt 54 to move downward by a specific distance. The linear extension mechanism 56 is reversely actuated to drive the left supporting plate 52 and the right supporting plate 53 to re-close. When a new tobacco piece appears, the above-mentioned actions are repeated until the lower conveying belt 54 is stacked with a specific number of tobacco pieces. The lower conveying belt 54 starts to act to convey the tobacco pieces to the second conveying belt 40.

[0094] When the stacked tobacco pieces of a specific number reach the cartoning station of the second conveying belt 40, the second conveying belt 40 stops conveying the tobacco pile forward, and the alignment mechanism 60 starts to act and moves to the position directly above the second conveying belt 40. Subsequently, the first Z-direction lifting mechanism 63 drives the first lifting frame 62 to move downward to a specific position. The X-direction extension 64, the Y-direction extension 65, and the Z-direction extension 68 simultaneously act to drive the X-direction pressing plate 65, the Y-direction pressing plate 67, and the Z-direction pressing plate 69 to gradually approach and extrude the tobacco pile, so as to realize the alignment of the tobacco pieces of a specific number. The aligned stacked tobacco pieces still stay on the second conveying belt 40, waiting for cartoning.

[0095] After the paper box 77 is inverted and sleeved on the sleeve box 75 by artificial, the movable flipper 76 is raised upward to support the four side sealing plates 78 of the paper box 77, the second Z-direction lifting mechanism 73 drives the second lifting frame 72 to move downward to a specific position, and the telescopic clamping piece 74 starts to act to clamp the four side sealing plates 78 of the paper box 77 respectively. Then, the second Z-direction lifting mechanism 73 reversely moves to take the paper box 77 from the sleeve box 75.

[0096] The sleeve box mechanism 70 is moved from the sleeve box station to the packing station, that is, the sleeve box mechanism 70 is moved to the upper side of the second conveying belt 40, the second Z-direction lifting mechanism 73 drives the paper box 77 to move downward to sleeve the multiple layers of tobacco blocks into the paper box 77, and the telescopic clamping piece 74 stops acting, and the sleeve box mechanism 70 returns to the initial state.

[0097] When the paper box 77 together with the multiple layers of tobacco blocks moves to the space between the lower clamping conveying belt 83 and the upper clamping conveying belt 82, the upper clamping conveying belt 82 starts to move downward to the lower clamping conveying belt 83 to clamp the paper box 77 together with the multiple layers of tobacco blocks. Then, the turnover support 81 drives the upper clamping conveying belt 82 and the lower clamping conveying belt 83 to turn 180° in the vertical plane to invert the paper box 77, that is, to make the opening of the paper box 77 upward. The lower clamping conveying belt 83 moves upward to release the paper box 77, and the upper clamping conveying belt 82 starts to convey the paper box 77 together with the multiple layers of tobacco blocks to the third conveying belt 90.

[0098] The third conveying belt 90 conveys the paper box 77 together with the multiple layers of tobacco blocks to the next process.

[0099] Compared with the prior art, the application has at least the following beneficial technical effects:

[0100] The horizontal pre-pressing and packing method in the application realizes the pre-pressing and packing of the tobacco strips by the belt pressing, following cutting, multiple layer stacking, automatic alignment, inversion and packing and clamping and turnover, can effectively solve many problems existing in the hydraulic pre-pressing machine, greatly reduces the equipment height, eliminates the risk of hydraulic oil leakage, improves the pressing uniformity and improves the pre-pressing and packing effect of the tobacco strips.

[0101] The application can effectively reduce the equipment height, improve the uniformity of the tobacco density, cancel the hydraulic driving mechanism, effectively prevent the problems such as pollution, burning, caking, oiling and mildewing of the tobacco after packing, improve the aging effect, and reduce the crushing and loss during the production of the tobacco strip production line.

[0102] The above is only the preferred embodiment of the application, and it should be pointed out that the ordinary skilled in the art can make several improvements and replacements without departing from the technical principles of the application, and these improvements and replacements should be regarded as the protection scope of the application.
