Description

Technical Field

[0001] The invention relates to the field of cigarette processing technology, and in particular to a cigarette block cutting combination system and method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The development of Chinese cigarettes has pushed the industry's product design to a new level. The production and sales of famous and high-quality cigarettes have increased significantly, leading the development and growth of cigarettes. The "multi-region, multi-grade, small proportion" formula design concept has been fully integrated into the entire product design, and is an important prerequisite for improving the product design level, ensuring stable product quality, and achieving sustainable development. Tobacco leaf raw materials are the basis for the design of product leaf group formulas. Since tobacco leaf raw materials are agricultural products, the quality of raw material acquisition will fluctuate every year due to climate change, field management, local interests, especially leaf beating and redrying formula leaf beating processing, and other reasons, and it is impossible to ensure continuous and stable supply year after year. Industrial enterprises have to invest a lot of energy every year to control the stability and consistency of tobacco leaf raw materials to ensure the stability of product formulas, and even spend a lot of money to carry out large-scale selection, purification, and uniform blending to solve the problem of raw material quality balance and consistency, resulting in an increase in the cost of raw material processing for enterprises year by year. Because the cost of raw material selection and processing, blending and redrying costs require a lot of funds every year, the cost of products has risen sharply, and the quality effect still does not meet the product standard requirements, which seriously restricts the healthy development of industrial enterprises.

The following is a detailed description through several embodiments:

[0049] Embodiment 2

[0050] In this embodiment, the tobacco block is 200 kg ± 2 kg, which is divided into 4 pieces, each weighing about 50 kg ± 0.5 kg. Figure 1 , Figure 2 , Figure 3 As shown:

[0051] Before the cigarette block 1 is conveyed to the chain conveyor 3, the elevating roller conveyor 6 can be lowered to the lowest position, that is, the height of the elevating roller conveyor 6 is lower than the top of the chain conveyor 3;

[0052] The unpacked cigarette block 1 is conveyed to the chain conveyor 3 through the belt conveyor 2. After the cigarette block 1 is in place, the liftable roller conveyor 6 automatically rises, and its top is pressed against the bottom of the cigarette block and lifts up the cigarette block 1. The cigarette block 1 falls on the liftable roller conveyor 6, and the bottom of the cigarette block 1 is 100 mm above the top of the chain conveyor 3. The weighing scale at the bottom of the liftable roller conveyor 6 can accurately weigh the weight of the cigarette block; after the cigarette block 1 is positioned, the push plate cylinder 4 on the chain conveyor 3 pushes the cigarette block push plate 5 to press the cigarette block 1, ready for cutting;

[0053] The rotatable frame 11 slides to the position for cutting the cigarette block, and rotates to align the cutting knife support frame 9 with the position of the cigarette block 1. The electric control system 30 calculates the cutting height of the cigarette block 1 through the height sensor 28. The lifting belt 26 of the cutting knife support frame drives the cutting knife 8 to move up and down and accurately aligns with the position of the cigarette block 1 to prepare for cutting the cigarette block 1.

[0054] The slitting knife cylinder 10 pushes the slitting knife 8 forward. When the slitting knife 8 is inserted horizontally into the cigarette block 1 and approaches the cigarette block push plate 5 on the chain conveyor 3, the cigarette sheet push plate small cylinder 15 on the slitting knife 8 is started to push the cigarette sheet push plate 14 to press the cut cigarette sheets.

[0055] The lifting belt 26 of the slitting knife support frame drives the slitting knife support frame 9 to move upward, driving the cut tobacco slices on the slitting knife 8 to move upward, and the cut tobacco slices are separated from the original tobacco block 1. The slitting knife cylinder 10 retracts and resets, driving the cut tobacco slices to move backward. During this period, the tobacco slice push plate 14 on the slitting knife 8 moves synchronously and presses the tobacco slices.

[0056] The rotatable frame 11 rotates 90° counterclockwise, and the tobacco slices enter the right position synchronously after slitting. The rotatable frame 11 moves on the slide rail 12. When the position sensor 7 on the right baffle plate 17 of the first rotatable belt conveyor detects the tobacco slices, the slitting knife cylinder 10 pushes the slitting knife 8 to move forward. During this period, the tobacco slice push plate 14 on the slitting knife 8 presses the tobacco slices and moves synchronously. The tobacco slices on the slitting knife 8 are horizontally inserted into the first rotatable belt conveyor 16. When the tobacco slices contact the push plate 23 of the first rotatable belt conveyor, the slitting knife cylinder 10 stops moving, and the left push plate 22 of the first rotatable belt conveyor pushes the tobacco slices and the slitting knife 8 It moves on the slitting knife slide 13. When the tobacco slices touch the right baffle 17 of the first rotatable belt conveyor, the left push plate 22 of the first rotatable belt conveyor stops pushing, and the slitting knife support frame lifting belt 26 drives the slitting knife support frame 9 to move downward. When the slitting knife 8 touches the bottom of the first rotatable belt conveyor 16, the slitting knife support frame lifting belt 26 stops moving, and the slitting knife cylinder 10 retreats. The tobacco slices on the slitting knife fall onto the first rotatable belt conveyor 16 under the obstruction of the tobacco slice push plate 14; after the slitting knife cylinder 10 is completely retreated, the tobacco slice push plate small cylinder 15 is retracted to drive the tobacco slice push plate 14 to reset.

[0057] After the rotatable frame 11 is reset to the position of cutting tobacco slices from the slide rail 12, it rotates counterclockwise 90° to cut the tobacco block for the next time. Repeat the above actions, the tobacco block cut twice enters the second rotatable belt conveyor 18, and the tobacco block cut three times enters the third rotatable belt conveyor 19. During the cutting of tobacco slices, the electronic control system calculates the weight of each slice at any time through the weighing scale at the bottom of the liftable roller conveyor. When the weight of the tobacco block after cutting exceeds the design value ±0.5 kg, the system reminds the manual feeding. After the manual feeding is completed, the next cutting action is implemented.

[0058] Finally, 1 / 4 of the tobacco slices are left. When the slitting knife moves to the top area of ​​the tobacco block and the chain conveyor 3, the liftable roller conveyor 6 is started, and at the same time, the push plate cylinder 4 installed on the chain conveyor 3 is started. The tobacco block push plate 5 pushes the tobacco block to move and pushes the tobacco block onto the slitting knife 8. The slitting knife support frame 9 drives the remaining 1 / 4 of the tobacco slices to move and conveys the tobacco slices to the fourth rotatable belt conveyor 20, completing the splitting of the entire tobacco block.

[0059] The next pack of cigarettes is split again, and the cigarette blocks are sliced ​​by the belt conveyor 2, the chain conveyor 3, the liftable roller conveyor 6 and the slitting knife 8 on the rotatable frame 11, and then conveyed to the first rotatable belt conveyor 16, the second rotatable belt conveyor 18, the third rotatable belt conveyor 19 and the fourth rotatable belt conveyor 20 to complete the cutting and packaging of the entire cigarette block.

[0060] After the cutting of all 4 packs of cigarette blocks is completed, the movable belt conveyor 25 moves to the right to provide space for the first rotatable belt conveyor 16 to rotate. The first rotatable belt conveyor 16 rotates 180°, and the movable belt conveyor 25 moves to the left. The first rotatable belt conveyor 16 starts to convey the re-cut cigarette blocks to the movable belt conveyor 25, and the movable belt conveyor 25 sends the cigarette blocks to the next process for boxing and packaging.

[0061] The second rotatable belt conveyor 18, the third rotatable belt conveyor 19 and the fourth rotatable belt conveyor 20 adopt the same action to convey the cigarette blocks to the movable belt conveyor for the next process of boxing and packaging.

[0062] The electronic control system 30 records the sheet grade information of each cigarette block, prints it and sticks it on the sealed cigarette box, thus completing the cutting and assembly of the entire cigarette block.

[0063] Example 3

[0064] In this embodiment, the cigarette block is 200 kg ± 2 kg, divided into 2 pieces, the first piece weighs about 50 kg ± 0.5 kg, and the second piece weighs about 350 kg ± 1.5 kg. Figure 1 , Figure 2 , Figure 3 As shown:

[0065] Before the tobacco blocks are cut, the elevating roller conveyor 6 is lowered to a height lower than the top of the chain conveyor 3;

[0066] The unpacked cigarette block 1 is conveyed to the chain conveyor 3 through the belt conveyor 2. After the cigarette block 1 is in place, the liftable roller conveyor 6 automatically rises to lift the cigarette block 1, and the cigarette block 1 falls on the liftable roller conveyor 6. The weighing scale at the bottom of the liftable roller conveyor 6 can accurately weigh the weight of the cigarette block; the push plate cylinder 4 on the chain conveyor 3 pushes the cigarette block push plate 5 to press the cigarette block 1, ready for cutting;

[0067] The rotatable frame 11 slides to the position of cutting the cigarette block, and rotates to align the cutting knife support frame 9 with the position of the cigarette block 1. The electric control system 30 calculates the cutting height of the first cigarette block 1 through the height sensor 28. The lifting belt 26 of the cutting knife support frame drives the cutting knife 8 to move up and down and accurately aligns with the position of the cigarette block 1 to prepare for cutting the cigarette block 1.

[0068] The slitting knife cylinder 10 pushes the slitting knife 8 forward. When the slitting knife 8 is inserted into the tobacco sheet 1 and approaches the tobacco block push plate 5 on the chain conveyor 3, the slitting knife cylinder 10 stops pushing, and the tobacco block push plate small cylinder 15 starts to push the tobacco block push plate 14 to press the cut tobacco sheets.

[0069] The lifting belt 26 of the slitting knife support frame drives the slitting knife support frame 9 to move upward, driving the cut tobacco slices on the slitting knife 8 to separate from the original tobacco block 1, and the slitting knife cylinder 10 retracts and resets, driving the cut tobacco slices to move backward. During this period, the tobacco slice push plate 14 on the slitting knife 8 moves synchronously and presses the tobacco slices.

[0070] The rotatable frame 11 rotates 90° counterclockwise, and the rotatable frame 11 moves on the slide rail 12. When the position sensor on the right baffle plate 17 of the first rotatable belt conveyor detects the tobacco slices, the slitting knife cylinder 10 pushes the slitting knife 8 to move forward. During this period, the tobacco slice push plate 14 on the slitting knife 8 presses the tobacco slices and moves synchronously. The tobacco slices on the slitting knife 8 are horizontally inserted into the first rotatable belt conveyor 16. When the tobacco slices contact the push plate 23 of the first rotatable belt conveyor, the slitting knife cylinder 10 stops moving, and the left push plate 22 of the first rotatable belt conveyor pushes the tobacco slices and the slitting knife 8 on the slitting knife slideway 1 3, when the tobacco sheet contacts the right baffle plate 17 of the first rotatable belt conveyor, the left push plate 22 of the first rotatable belt conveyor stops pushing, and the slitting knife support frame lifting belt 26 drives the slitting knife support frame 9 to move downward. When the slitting knife 8 contacts the bottom of the first rotatable belt conveyor 16, the slitting knife support frame lifting belt 26 stops moving, and the slitting knife cylinder 10 retreats. The tobacco sheet on the slitting knife falls on the first rotatable belt conveyor 16 under the obstruction of the tobacco sheet push plate 14; after the slitting knife cylinder 10 is completely retreated, the tobacco sheet push plate small cylinder 15 is retracted to drive the tobacco sheet push plate 14 to reset.

[0071] After the rotatable frame 11 is reset to the position for cutting tobacco slices from the slide rail 12, it rotates counterclockwise 90° to cut the tobacco block next time. During this period, the electronic control system calculates the weight of each slice through the weighing scale at the bottom of the liftable roller conveyor. When the weight of the tobacco block after cutting exceeds the design value ±0.5 kg, the system reminds the manual feeding. After the manual feeding is completed, the next cutting action is carried out.

[0072] When the slitting knife 8 moves to the top area of ​​the cigarette block and the chain conveyor 3, the liftable roller conveyor 6 starts, and at the same time, the push plate cylinder 4 installed on the chain conveyor 3 starts, and the cigarette block push plate 5 pushes the cigarette block to move, pushes the cigarette block onto the slitting knife 8, and the slitting knife support frame 9 drives the remaining 1 / 2 cigarette pieces to move and conveys the cigarette pieces to the second rotatable belt conveyor 18, completing the splitting of the entire cigarette block.

[0073] The next pack of cigarettes is split again. After the cigarette blocks are sliced ​​by the belt conveyor 2, the chain conveyor 3, the liftable roller conveyor 6 and the slitting knife 8 on the rotatable frame 11, 1 / 4 of the cigarette slices are conveyed to the second rotatable belt conveyor 18, and the remaining 3 / 4 of the cigarette slices are conveyed to the first rotatable belt conveyor 16, completing the cutting and packaging of the second cigarette block.

[0074] After the cutting of the two packs of cigarette blocks is completed, the movable belt conveyor 25 moves to the right to provide space for the first rotatable belt conveyor 16 to rotate. The first rotatable belt conveyor 16 rotates 180°, and the movable belt conveyor 25 moves to the left. The first rotatable belt conveyor 16 starts to convey the re-cut cigarette blocks to the movable belt conveyor 25, and the movable belt conveyor 25 sends the cigarette blocks to the next process for boxing and packaging; the second rotatable belt conveyor adopts the same action to transport the cigarette blocks to the movable belt conveyor for the next process of boxing and packaging.

[0075] The electronic control system 30 records the sheet grade information of each cigarette block, prints it and sticks it on the sealed cigarette box, thus completing the cutting and assembly of the entire cigarette block.

[0079] The unpacked cigarette block 1 is conveyed to the chain conveyor 3 through the belt conveyor 2. The lifting roller conveyor 6 automatically rises to lift the cigarette block 1. The weighing scale at the bottom of the lifting roller conveyor 6 accurately weighs the weight of the cigarette block. The push plate cylinder 4 on the chain conveyor 3 pushes the cigarette block push plate 5 to press the cigarette block 1, ready for cutting.

[0080] The rotatable frame 11 slides to the position of cutting the cigarette blocks, and rotates to align the cutting knife support frame 9 with the position of the cigarette block 1. The electric control system 30 calculates the cutting height of the first cigarette block 1 through the height sensor 28. The lifting belt 26 of the cutting knife support frame drives the cutting knife 8 to move up and down, and accurately aligns with the position of the cigarette block 1 to cut the cigarette block 1.

[0081] The slitting knife cylinder 10 pushes the slitting knife 8 forward, and the slitting knife 8 is inserted horizontally into the tobacco sheet 1. The tobacco sheet push plate small cylinder 15 is started to push the tobacco sheet push plate 14 to press the cut tobacco sheet;

[0082] The slitting knife support frame lifting belt 26 drives the slitting knife support frame 9 to move upward, driving the cut tobacco sheets on the slitting knife 8 to move, during which the tobacco sheet pusher 14 on the slitting knife 8 moves synchronously and presses the tobacco sheets.

[0083] The rotatable frame 11 rotates 90° counterclockwise and moves on the slide rail 12 to place the cut tobacco sheets on the first rotatable belt conveyor;

[0084] After the rotatable frame 11 is reset to the position of cutting tobacco slices from the slide rail 12, it rotates counterclockwise 90° to cut the tobacco block next time. During this period, the electronic control system calculates the weight of each slice through the weighing scale at the bottom of the liftable roller conveyor. When the weight of the tobacco block after cutting exceeds the design value ±1.0 kg, the system reminds the manual feeding. After the manual feeding is completed, the next cutting action is implemented.

[0085] When the slitting knife 8 moves to the top area of ​​the cigarette block and the chain conveyor 3, the liftable roller conveyor 6 starts, and at the same time, the push plate cylinder 4 installed on the chain conveyor 3 starts, and the cigarette block push plate 5 pushes the cigarette block to move, pushes the cigarette block onto the slitting knife 8, and the slitting knife support frame 9 drives the remaining 1 / 2 cigarette pieces to move and conveys the cigarette pieces to the second rotatable belt conveyor 18, completing the splitting of the entire cigarette block.

[0086] The next pack of cigarettes is split again. After the cigarette blocks are sliced ​​by the belt conveyor 2, the chain conveyor 3, the liftable roller conveyor 6 and the slitting knife 8 on the rotatable frame 11, 1 / 2 of the cigarette slices are conveyed to the second rotatable belt conveyor 18, and the remaining 1 / 2 of the cigarette slices are conveyed to the first rotatable belt conveyor 16, completing the cutting and packaging of the second cigarette block.

[0087] After the cutting of the two packs of cigarette blocks is completed, the movable belt conveyor 25 moves to the right to provide space for the first rotatable belt conveyor 16 to rotate. The first rotatable belt conveyor 16 rotates 180°, and the movable belt conveyor 25 moves to the left. The first rotatable belt conveyor 16 starts to convey the re-cut cigarette blocks to the movable belt conveyor 25, and the movable belt conveyor 25 sends the cigarette blocks to the next process for boxing and packaging; the second rotatable belt conveyor adopts the same action to transport the cigarette blocks to the movable belt conveyor for the next process of boxing and packaging.

[0088] The electronic control system 30 records the sheet grade information of each cigarette block, prints it and sticks it on the sealed cigarette box, thus completing the cutting and assembly of the entire cigarette block.

[0089] The product formula design of the present invention can be based on the concept of "multi-region, multi-grade, small proportion (the lowest single formula grade is reduced from 200 kg to 50 kg)", and the leaf group formula combination design can be arbitrarily carried out, which lays a solid foundation for improving the product design level and controlling the stability of product quality.
