[0055] Examples, such as Figure 1-Figure 8 As shown, a horizontal pre-pressing and packing device for producing tobacco strips is used for pre-pressing and packing tobacco strips; the device comprises a belt-type 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 packing 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 rotating 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 loosely stacked tobacco sheets can be continuously compressed, formed and discharged.

[0057] The first conveyor belt 20 is disposed between the belt pressing mechanism 10 and the stacking mechanism 50 along the transverse direction, and is used to convey the cut cigarette blocks to the stacking 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 laterally 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 box turning mechanism 80 , and the second conveyor belt 40 can intermittently convey cigarette packs and cartons 77 to the box 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 conveyor belt 40, and the avoidance station is arranged on one side of the second conveyor belt 40. The alignment mechanism 60 can move back and forth between the alignment station and the avoidance station to stack the cigarette blocks stacked on the second conveyor belt 40 into cigarette stacks.

[0062] The packing mechanism 70 has a box-packing station and a box-packing station. The box-packing station is arranged on the second conveyor belt 40, and the box-packing station is arranged on the other side of the second conveyor belt 40. The box-packing mechanism 70 can move back and forth between the box-packing station and the box-packing station, and is used to put the carton 77 with the opening downward on the outside of the cigarette stack.

[0063] The box turning mechanism 80 is disposed at the unloading end of the second conveyor belt 40 , and the box turning mechanism 80 can clamp the carton 77 up and down and turn the carton 77 180 degrees before outputting it.

[0064] The present application adopts a horizontal structure, and the belt pressing mechanism 10, the first conveyor belt 20, the cutting mechanism 30, the second conveyor belt 40, the stacking mechanism 50 and the box turning mechanism 80 are horizontally arranged along the material conveying direction, and the alignment mechanism 60 and the box packing mechanism 70 are arranged on both sides of the second conveyor belt 40. The tobacco blocks on the second conveyor belt 40 are stacked and boxed in turn by the alignment mechanism 60 and the box packing mechanism 70, which can not only greatly reduce the height of the pre-pressing and boxing device, but also realize the automatic pre-pressing and boxing of the tobacco leaves; the present application continuously compresses the loose tobacco leaves in the silo 15 through the inclined upper pressing conveyor belt 11 and the lower pressing conveyor belt 12, and cooperates with the push plate 13 to periodically push the tobacco leaves in the silo 15, which can improve the uniformity of the tobacco pack density and improve the aging effect of the tobacco pack, reduce the production and operation costs, improve the technical level of leaf threshing and re-roasting equipment and save raw materials.

[0065] In a specific embodiment, if Figure 1 , Figure 2 As shown, the belt-type pressing mechanism 10 includes an upper pressing conveyor belt 11, a lower pressing conveyor belt 12, a pushing plate 13 and a bin plate 14; wherein, there are two bin plates 14, and the two bin plates 14 are arranged in parallel, one in front of the other, and a bottom plate 16 is fixedly connected to the bottom of the two bin plates 14, and a bin 15 is enclosed between the two bin plates 14 and the bottom plate 16.

[0066] The upper pressing conveyor belt 11, the lower pressing conveyor belt 12 and the push plate 13 are arranged in the silo 15, the upper pressing conveyor belt 11 is arranged directly above the lower pressing conveyor belt 12, and the upper pressing conveyor belt 11 is arranged obliquely downward, and the lower pressing conveyor belt 12 is arranged obliquely upward, so that the feeding end spacing of the upper pressing conveyor belt 11 and the lower pressing conveyor belt 12 is larger than the discharging end spacing, that is, the left end spacing of the upper pressing conveyor belt 11 and the lower pressing conveyor belt 12 is larger than the right end spacing.

[0067] The push plate 13 is vertically arranged just above the loading end of the lower pressing conveyor belt 12, that is, the push plate 13 is vertically arranged 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 that of the lower pressing conveyor belt 12, so that a feed port of the bin 15 is formed between the push plate 13 and the feeding end of the upper pressing conveyor belt 11, that is, a feed port of the bin 15 is formed between the push plate 13 and the left end of the upper pressing conveyor belt 11.

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

[0069] Specifically, 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 cigarette sheets fall into the silo 15 from the feed port, they are stacked 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 cigarette sheets, the cigarette sheets 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 in parallel just above the first conveyor belt 20, 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 reciprocate laterally; 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 output from the belt-type pressing mechanism 10 to the first conveyor belt 20, the continuous tobacco block will move forward synchronously with the first conveyor belt 20. In this embodiment, the longitudinal mounting plate 34 can be driven by the lateral moving mechanism 32 to drive the cutter lifting mechanism 33 and the lifting cutter 31 to move horizontally synchronously with the continuous tobacco block, so as to ensure that when the lifting cutter 31 cuts the continuous tobacco block downward, the tobacco block is cut flat and a rectangular tobacco block of a specific length is obtained.

[0073] Preferably, the lateral 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 stacking 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, 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 pallet 52 and the right pallet 53 are arranged in parallel, one on the left and the other on the right, between the upper fixed frame 51 and the lower conveyor belt 54, and are used to receive and support the tobacco blocks transported by the first conveyor belt 20. The support beam 55 is arranged in parallel just above the lower conveyor belt 54, and both ends of the support beam 55 are fixedly connected to the upper fixed frame 51; a vertical plate 58 is vertically connected to the ends of the left pallet 52 and the right pallet away from each other, the middle part of the linear telescopic mechanism 56 is fixedly connected to the support beam 55, and the two ends of the linear telescopic mechanism 56 are fixedly connected to the two vertical plates 58 in a one-to-one correspondence, so that the left pallet 52 and the right pallet 53 can be driven to move in opposite directions through the linear telescopic mechanism 56, so that the tobacco blocks on the left pallet 52 and the right pallet 53 fall onto the lower conveyor belt 54 under the action of gravity.

[0076] Preferably, the linear telescopic mechanism 56 and the linear lifting mechanism 57 are both lead screws driven by motors.

[0077] In a specific embodiment, if Figure 1 , Figure 5 As shown, 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 telescopic member 64, an X-direction pressure plate 65, a Y-direction telescopic member 66, a Y-direction pressure plate 67, a Z-direction telescopic member 68 and a Z-direction pressure plate 69; wherein, the first fixed frame 61 is a plane frame, the first lifting frame 62 is a three-dimensional frame, and the first lifting frame 62 is liftably arranged directly below the first fixed frame 61, and 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 to the middle part of the first fixed frame 61, and the lifting end of the first Z-direction lifting mechanism 63 is fixedly connected to the middle part of the first lifting frame 62, so as to drive the first lifting frame 62 to rise or fall through the first Z-direction lifting mechanism 63.

[0078] A Z-axis pressure plate 69, two X-axis pressure plates 65 and two Y-axis pressure plates 67 are arranged on the inner side of the first lifting frame 62; the Z-axis pressure plate 69 is horizontally arranged at the top of the inner cavity of the first lifting frame 62, and the Z-axis telescopic member 68 is connected between the first lifting frame 62 and the Z-axis pressure plate 69 to drive the Z-axis pressure plate 69 to rise and fall through the Z-axis telescopic member 68; the two X-axis pressure plates 65 are arranged in parallel at both ends of the inner cavity of the first lifting frame 62 in the transverse direction, and the two X-axis telescopic members 64 are connected one-to-one between the first lifting frame 62 and the X-axis pressure plate 65 to drive the two X-axis pressure plates 65 to move in reverse; the two Y-axis telescopic members 66 are arranged in parallel at both ends of the inner cavity of the first lifting frame 62 in the longitudinal direction, and the two Y-axis telescopic members 66 are connected one-to-one between the first lifting frame 62 and the Y-axis pressure plate 67 to drive the two Y-axis pressure plates 67 to move in reverse.

[0079] The reason for such arrangement is that the stacking mechanism 50 can only stack the cigarette blocks regularly on the second conveyor belt 40, but the flatness of the stacking of the cigarette blocks does not meet the packing requirements. In this embodiment, when the cigarette pile on the second conveyor belt 40 moves to the alignment station, the second conveyor belt 40 stops moving, and the alignment mechanism 60 moves longitudinally from the avoidance station to the alignment station, and drives the first lifting frame 62 to descend to the outside of the cigarette pile through the first Z-direction lifting mechanism 63, and then drives the X-direction pressing plate 65, the Y-direction pressing plate 67 and the Z-direction pressing plate 69 to squeeze the cigarette pile through the extension of the X-direction telescopic member 64, the Y-direction telescopic member 66 and the Z-direction telescopic member 68, so as to stack the cigarette pile into a neat cigarette stack.

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

[0081] In a specific embodiment, if Figure 1 , Figure 6 , Figure 7 As shown, the packing mechanism 70 includes a second fixed frame 71, a second lifting frame 72, a second Z-direction lifting mechanism 73, a telescopic clamping member 74, a sleeve box 75 and a movable flap 76; wherein, the sleeve box 75 is fixedly arranged at the sleeve box station, and movable flaps 76 cooperating with the sealing plate 78 of the carton 77 are provided on the four sides of the sleeve box 75, so that the sealing plate 78 of the carton 77 sleeved on the sleeve box 75 can be flipped upward through the mutual cooperation between the movable flaps 76 and the sealing plate 78.

[0082] The second fixed frame 71 is a plane frame, and the second lifting frame 72 is a three-dimensional frame. The second lifting frame 72 is liftable and arranged directly below the second fixed frame 71, and guide columns 79 are provided 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 part of the second fixed frame 71, and the lifting end of the second Z-direction lifting mechanism 73 is fixedly connected to the middle part of the second lifting frame 72, so as to drive the second lifting frame 72 to rise or fall through the second Z-direction lifting mechanism 73.

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

[0084] This arrangement is because: at the box-putting station, after the carton 77 is manually put on the top of the box 75 with its opening facing downward, the four sealing plates 78 of the carton 77 will tilt upward under the action of the movable flaps 76; when the packing mechanism 70 moves longitudinally from the box-putting station to the box-packing station, the carton 77 can be driven to be put on the outside of the cigarette stack through the second Z-axis lifting mechanism 73.

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

[0086] In a specific embodiment, if Figure 1 , Figure 8 As shown, the box turning mechanism 80 is arranged between the second conveyor belt 40 and the third conveyor belt 90, and the box turning mechanism 80 includes a flipping bracket 81, an upper clamping conveyor belt 82 and a lower clamping conveyor belt 83; wherein, the upper clamping conveyor belt 82 and the lower clamping conveyor belt 83 are arranged in parallel up and down, the flipping bracket 81 is connected between the upper clamping conveyor belt 82 and the lower clamping conveyor belt 83, and the flipping bracket 81 can flip the upper clamping conveyor belt 82 and the lower clamping conveyor belt 83 180° in the vertical plane, and at the same time, the spacing between the upper clamping conveyor belt 82 and the lower clamping conveyor belt 83 can be adjusted, so that the carton 77 conveyed by the second conveyor belt 40 to the lower clamping conveyor belt 83 is flipped 180° and then conveyed to the third conveyor belt 90.

[0087] This arrangement is because: the carton 77 is opened downward on the second conveyor belt 40, and the carton 77 needs to be opened upward when it is on the third conveyor belt 90. In this embodiment, after the second conveyor belt 40 conveys the carton 77 between the upper clamping conveyor belt 82 and the lower clamping conveyor belt 83, the upper clamping conveyor belt 82 moves downward to clamp the carton 77 with the lower clamping conveyor belt 83, and the upper clamping conveyor belt 82 and the lower clamping conveyor belt 83 are driven to flip 180° through the flip bracket 81, and then the lower clamping conveyor belt 83 located on the upper side moves upward to release the carton 77, and the upper clamping conveyor belt 82 located on the lower side conveys the carton 77 with the opening upward to the third conveyor belt 90.

[0088] It should be noted that the specific structure of the flip bracket 81, and the lifting and lowering of the upper clamping conveyor belt 82 and the lower clamping conveyor belt 83 are prior arts and will not be described in detail here.

[0089] In a specific embodiment, the alignment mechanism 60 and the boxing mechanism 70 are symmetrically arranged on both sides of the second conveyor belt 40 in the longitudinal direction, and the alignment station of the alignment mechanism 60 and the boxing station of the boxing mechanism 70 overlap, and the avoidance station of the alignment mechanism 60 and the boxing station of the boxing mechanism 70 are symmetrically arranged on both sides of the second conveyor belt 40, so that after the alignment mechanism 60 stacks the cigarettes on the second conveyor belt 40 into cigarette stacks, the boxing mechanism 70 can accurately put the carton 77 on the cigarette stack.

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

[0091] The cigarette sheets to be pressed into the carton 77 enter the hopper 15 along the feeding direction, and the push plate 13 swings back and forth periodically at a specific frequency to push the cigarette sheets forward. The upper compaction belt 113 moves in the counterclockwise direction under the drive of the upper drive roller 111, and the lower compaction belt 123 moves in the clockwise direction under the drive of the lower drive roller 121. The loose cigarette sheets move in the discharge direction under the pressure of the upper compaction belt 113 and the lower compaction belt 123, and are continuously compressed during this period. By the time of discharge, the cigarette sheets have become compacted cigarette blocks with a fixed width and thickness, and move to the first conveyor belt 20.

[0092] When the compacted tobacco block moves forward over a specific length on the first conveyor belt 20, the cutter lifting mechanism 33 drives the lifting cutter 31 to move downward to cut off the continuously extruded compacted tobacco block. During this period, the transverse moving mechanism 32 drives the lifting cutter 31 to move forward synchronously with the first conveyor belt 20, that is, the transverse moving speed of the lifting cutter 31 is consistent with the belt speed of the first conveyor belt 20; then the cutter lifting mechanism 33 and the transverse moving mechanism 32 move in opposite directions successively to drive the lifting cutter 31 to return to the initial position.

[0093] When the cut cigarette blocks are transported to the stacking mechanism 50, the linear telescopic mechanism 56 is activated to drive the left support plate 52 to move to the left, and at the same time drive the right support plate 53 to move to the right, and the cigarette blocks naturally fall to the lower conveyor belt 54 under the action of gravity. Subsequently, the linear lifting mechanism 57 drives the lower conveyor belt 54 to move downward a specific distance. The linear telescopic mechanism 56 acts in the opposite direction to drive the left support plate 52 and the right support plate 53 to close again. When new cigarette blocks appear, the above actions are repeated until a specific number of layers of cigarette blocks are stacked on the lower conveyor belt 54, and the lower conveyor belt 54 starts to move to transport the cigarette blocks to the second conveyor belt 40.

[0094] When a specific number of stacked cigarette blocks arrive at the packing station of the second conveyor belt 40, the second conveyor belt 40 stops conveying the cigarette blocks forward, and the alignment mechanism 60 starts to move and moves to the top of the second conveyor belt 40; then, the first Z-direction lifting mechanism 63 drives the first lifting frame 62 to move downward to a specific position. The X-direction telescopic member 64, the Y-direction telescopic member and the Z-direction telescopic member 68 move simultaneously, driving the X-direction pressing plate 65, the Y-direction pressing plate 67 and the Z-direction pressing plate 69 to gradually approach and squeeze the cigarette blocks, so as to achieve the alignment of the specific number of layers of cigarette blocks. The aligned stacked cigarette blocks remain on the second conveyor belt 40, waiting to be packed.

[0095] After the carton 77 is manually placed upside down on the sleeve box 75, the movable claws 76 tilt upward to push the four sealing plates 78 of the carton 77 upward; the second Z-direction lifting mechanism 73 drives the second lifting frame 72 to move downward to a specific position, and the telescopic clamping member 74 starts to move to clamp the four sealing plates 78 of the carton 77. Then, the second Z-direction lifting mechanism 73 moves in the opposite direction to lift the carton 77 from the sleeve box 75.

[0096] The packing mechanism 70 moves from the box inserting station to the box packing station, that is, the box packing mechanism 70 moves to the top of the second conveyor belt 40, and the second Z-axis lifting mechanism 73 drives the carton 77 downward to insert the multi-layer cigarette block into the carton 77, and the telescopic clamping member 74 stops moving, and the box packing mechanism 70 returns to its initial state.

[0097] When the carton 77 and the multi-layered cigarette blocks therein move between the lower clamping conveyor belt 83 and the upper clamping conveyor belt 82, the upper clamping conveyor belt 82 starts to move toward the lower clamping conveyor belt 83, thereby clamping the carton 77 and the multi-layered cigarette blocks therein. Subsequently, the flip bracket 81 drives the upper clamping conveyor belt 82 and the lower clamping conveyor belt 83 to flip 180° in the vertical plane, thereby turning the carton 77 right side up, that is, making the carton 77 open upward. The lower clamping conveyor belt 83 moves upward to release the carton 77, and the upper clamping conveyor belt 82 starts to transport the carton 77 and the multi-layered cigarette blocks therein to the third conveyor belt 90.

[0098] The third conveyor belt 90 transports the carton 77 together with the multi-layered cigarette blocks therein to the next process.

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

[0100] The horizontal pre-pressing and packing method in the present application realizes the pre-pressing and packing of tobacco leaves through belt compaction, follow-up cutting, multi-layer stacking, automatic alignment, inverted packing and clamping and flipping. It can effectively solve many problems existing in hydraulic pre-pressing machines, greatly reduce the height of the equipment, eliminate the risk of hydraulic oil leakage, improve the compaction uniformity, and improve the pre-pressing and packaging effect of tobacco leaves.

[0101] The present application can effectively reduce the height of the equipment, improve the uniformity of the density of the cigarette packs, eliminate the hydraulic drive mechanism, effectively prevent the problems of contamination, burning, caking, oiling, mildew, etc. of the cigarette packs after packing, improve the aging effect, and at the same time reduce breakage and losses during the production of silk thread making.

[0102] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
