Description

Technical Field

[0001] This invention relates to the field of tobacco processing technology, and in particular to an automatic tobacco stem pack opening, feeding, and stem pack recycling device. Background Technology

[0002] Tobacco stems are the coarse, hard veins of tobacco leaves. Nicotine, solanol, nicotinic acid, pectin, and plant proteins can be extracted from tobacco stems. Every year, a large amount of tobacco stem waste is discarded and wasted, which not only wastes natural resources but also causes environmental pollution. Therefore, the recycling and reuse of tobacco stems has not only economic value but also social value.

[0003] Currently, before tobacco stems can be recycled, entire bags of tobacco stems need to be transported to the work area, where they are manually cut open to allow the stems to fall into the tobacco stem reprocessing equipment. Because tobacco stems are irregularly shaped, various entanglements occur between them, preventing the cut stems from falling smoothly into the equipment. Even when they do fall into the equipment, they clump together, making further processing difficult. This requires manual labor to painstakingly remove the stems from the full bags, resulting in wasted manpower. Furthermore, after the tobacco stem bags are emptied, the empty bags, being irregularly shaped, cannot be neatly placed like empty boxes. They are often discarded haphazardly in corners or around the feeding devices, leading to a chaotic work environment. Additionally, staff cannot accurately count the number of tobacco stem bags opened based on the number of empty bags. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0045] like Figures 1 to 8 As shown, the present invention provides an automatic tobacco stem pack opening and feeding and stem pack recycling device, including a full stem pack conveying mechanism 1, a stem pack translation mechanism 2, a pack opening and feeding mechanism 3, and an empty pack recycling mechanism 4.

[0046] The full stem bag conveying mechanism 1, the opening and feeding mechanism 3, and the empty bag recycling mechanism 4 are arranged end to end from left to right. The full stem bag conveying mechanism 1 is used to transport full stem bags from the left end to the right end. The left end of the stem bag translating mechanism 2 is positioned above the right end of the full stem bag conveying mechanism 1, and the right end of the stem bag translating mechanism 2 is positioned above the empty bag recycling mechanism 4. The stem bag translating mechanism 2 is used to transport full stem bags through the opening and feeding mechanism 3 to the empty bag recycling mechanism 4. The opening and feeding mechanism 3 is used to open the full stem bags and empty the stems from them. The empty bag recycling mechanism 4 is used to recycle the empty packaging bags from the stem bags transported by the stem bag translating mechanism 2. The central axes of the full stem bag conveying mechanism 1, the opening and feeding mechanism 3, the empty bag recycling mechanism 4, and the stem bag translating mechanism 2 are located on the same straight line.

[0047] A full stem bag is placed from the left end of the full stem bag conveyor 1 and then conveyed from the left end to the right end by the full stem bag conveyor 1. During the conveying process, the orientation of the full stem bag is straightened and the horizontal position of the full stem bag is centered to facilitate the positioning and grabbing of the full stem bag from both sides by the stem bag translation mechanism 2. After the stem bag translation mechanism 2 grabs the full stem bag from both sides, it carries the full stem bag through the opening and feeding mechanism 3. The opening and feeding mechanism 3 opens the bottom of the full stem bag and empties the tobacco stems in the full stem bag, allowing the tobacco stems to fall into the bottom of the opening and feeding mechanism 3 to achieve feeding. Then the stem bag translation mechanism 2 carries the empty tobacco stem bag to the empty bag recycling mechanism 4 for orderly recycling of the empty packaging bag.

[0048] In some embodiments, the full-straw bag conveying mechanism 1 includes a conveyor frame 11. A front conveyor motor 12 and a rear conveyor motor 13 are fixedly connected to both sides of the left end of the conveyor frame 11. The front conveyor motor 12 and the rear conveyor motor 13 have the same specifications. The output pulley of the front conveyor motor 12 is wound with a front conveyor belt 14, and the output pulley of the rear conveyor motor 13 is wound with a rear conveyor belt 15. The front conveyor belt 14 and the rear conveyor belt 15 have the same specifications and are symmetrically arranged on the outside of the conveyor frame 11. A lifting baffle 16 is fixedly connected to the middle of the conveyor frame 11 through a horizontal bar. A front normally closed switch 17 and a rear normally closed switch 18 are fixedly connected to both ends of the lifting baffle 16. The front normally closed switch 17 is connected in series with the circuit of the front conveyor motor 12, and the rear normally closed switch 18 is connected in series with the circuit of the rear conveyor motor 13. Horizontal electric cylinders 19 are vertically fixed in the horizontal direction on both sides of the middle of the conveyor frame 11. The two horizontal electric cylinders 19 move synchronously in opposite directions, and the telescopic rods of the two horizontal electric cylinders 19 are fixedly connected to a central clamping plate 20.

[0049] A full bag of stems is placed on the top left side of the conveyor frame 11. When the front conveyor motor 12 and the rear conveyor motor 13 rotate at the same speed and in the same direction, the full bag is moved horizontally from the left end of the conveyor frame 11 to the right end via the front conveyor belt 14 and the rear conveyor belt 15. Midway, the lifting baffle 16 rises to catch the moving full bag. When the moving full bag is tilted, the front side of the full bag will first press against the front normally closed switch 17, causing the front conveyor motor 12 to stop and the front conveyor belt 14 to also stop moving the front side of the full bag. The rear conveyor motor 13 and the rear conveyor belt 15 continue to move the rear side of the full bag until the rear side of the full bag presses against the rear normally closed switch 18, at which point the rear conveyor motor 13 and the rear conveyor belt 15 stop moving. 15 also stops conveying full stem bags. At this time, the full stem bags are in a straight position. When the front normally closed switch 17 and the rear normally closed switch 18 are triggered at the same time, the circuit simultaneously connects the start switches of the two horizontal electric cylinders 19, causing the two horizontal electric cylinders 19 to retract the set distance at the same time. The full stem bags are pulled to the center position of the conveyor frame 11 through the center clamp 20. Then the lifting baffle 16 descends below the top surface of the conveyor frame 11. The front normally closed switch 17 reconnects the circuit of the front conveyor motor 12, and the rear normally closed switch 18 reconnects the circuit of the rear conveyor motor 13. The front conveyor motor 12 and the rear conveyor motor 13 start at the same speed, driving the straightened and center position of the full stem bag to continue to move horizontally to the right end of the conveyor frame 11, so that it can be grabbed by the stem bag horizontal movement mechanism 2.

[0050] In some embodiments, the stalk translation mechanism 2 includes a horizontal frame 21 with a transfer carriage 22 movably fitted along the axis of the horizontal frame 21. The transfer carriage 22 reciprocates along the axis of the horizontal frame 21 at the top of the horizontal frame 21. A front slide plate 23 and a rear slide plate 24 are symmetrically fitted at both ends of the bottom surface of the transfer carriage 22. A double-ended reverse screw 25 is rotatably connected to the middle of the transfer carriage 22. The two ends of the double-ended reverse screw 25 are respectively screwed to the front slide plate 23 and the rear slide plate 24. A tension motor 26 is fixedly connected to the side wall of the transfer carriage 22. The output shaft of the tension motor 26 is fixedly connected to the double-ended reverse screw 25. A front telescopic rod 27 is fixedly fixed to the bottom end of the front slide plate 23, and a rear telescopic rod 28 is fixedly fixed to the bottom end of the rear slide plate 24. Stalk clamps 29 are fixedly connected to the bottom ends of both the front telescopic rod 27 and the rear telescopic rod 28. The clamping openings of the two stalk clamps 29 are arranged opposite to each other.

[0051] As described above, the left end of the horizontal frame 21 is directly above the right end of the conveyor frame 11. When the transfer car 22 moves left along the horizontal frame 21 to directly above the right end of the conveyor frame 11, the tension motor 26, through the double-headed reverse screw 25, causes the front slide plate 23 and the rear slide plate 24 to move away from each other to the positions on both sides of the full stem bag. At this time, the front telescopic rod 27, the rear telescopic rod 28, and the two stem bag clamps 29 also move away. The lengths of the front telescopic rod 27 and the rear telescopic rod 28 are adjusted so that the center height of the two stem bag clamps 29 is on the same horizontal plane as the two sides of the full stem bag. When the two stem bag clamps 29 open, the two sides of the full stem bag that have moved from the left end of the conveyor frame 11 enter the two... The two clamping openings of the stem bag clamps 29 are opened. At this time, the two stem bag clamps 29 are closed to clamp the two sides of the full stem bag. Then, the front telescopic rod 27 and the rear telescopic rod 28 retract a certain distance at the same time, and the full stem bag held by the two stem bag clamps 29 rises a set distance. Then, when the transfer car 22 moves to the right along the horizontal frame 21, the transfer car 22 moves the full stem bags to the top of the opening and feeding mechanism 3 for opening and feeding. Finally, the transfer car 22 moves to the top of the empty bag recycling mechanism 4 to recycle the empty bags. After the above process is completed, the transfer car 22 moves to the left to the top of the right end of the conveyor frame 11 and repeats the above series of operations for the next row of full stem bags.

[0052] In some embodiments, the unpacking and feeding mechanism 3 includes a relay hopper 31. The left end of the relay hopper 31 is connected to the right end of the full-stem bag conveying mechanism 1. A serrated blade 32 is rotatably connected to the left side of the top opening of the relay hopper 31 via a transverse rotating shaft. A combing claw 33 is rotatably connected to the middle of the top opening of the relay hopper 31 via a transverse rotating shaft. A cutting motor 34 and a combing motor 35 are fixedly connected to the side of the relay hopper 31. The output shaft of the cutting motor 34 is driven to the serrated blade 32, and the output shaft of the combing motor 35 is driven to the combing claw 33. The bottom end of the inner cavity of the relay hopper 31 is connected to a feeding auger 36.

[0053] When opening and loading the tobacco, the cutting motor 34 is started first. The cutting motor 34 drives the serrated blade 32 to rotate. When the full tobacco bag is carried to the opening at the top of the relay hopper 31 by the tobacco bag translation mechanism 2, the bottom side of the full tobacco bag will be cut by the rotating serrated blade 32. After the tobacco stems leak out from the cut, because the tobacco stems have the characteristics of mutual attraction and entanglement, and the tobacco stems and the tobacco bag are also mutually attracted, the leaked tobacco stems will not fall into the relay hopper 31 quickly like granular or liquid items, but will gather at the cut. At this time, the combing motor 35 is started. The combing motor 35 drives the combing claw 33 to gradually comb the tobacco stems blocked at the cut into the inner cavity of the relay hopper 31. The tobacco stems that fall into the relay hopper 31 are then conveyed out by the feeding auger 36 at the bottom of the relay hopper 31 to complete the loading.

[0054] In some embodiments, a vertical electric cylinder 6 is fixedly connected to the middle of the transfer vehicle 22, a vibration motor 7 is fixedly connected to the bottom of the vertical electric cylinder 6, a flywheel 8 is fixedly connected to both ends of the output shaft of the vibration motor 7, and a flexible whip 9 is fixedly connected to the sides of both flywheels 8.

[0055] Because the tobacco stems are intertwined and also entangled with each other in the stem bundle, even with rotating combing claws 33 installed on the bottom side of the cut opening of the stem bundle, the combing claws 33 can only comb the tobacco stems at the cut opening into the intermediate hopper 31. They are powerless to comb the tobacco stems far from the cut opening. At this time, the vibration motor 7 can be activated. The vibration motor 7 drives the flexible whip 9 to rotate through two flywheel discs 8, whipping the top surface of the tobacco stem bundle. During the whipping process, the intertwined tobacco stems are loosened by the vibration and gradually move away. The tobacco stems are moved to the cut at the bottom of the tobacco stem pack. During this process, the forward-starting tension motor 26 can be activated to bring the front slide plate 23 and the rear slide plate 24 closer together through the double-headed reverse screw 25. As a result, the two stem pack clamps 29 holding the two ends of the tobacco stem pack also move closer together. At this time, the tobacco stems at both ends of the tobacco stem pack gradually gather at the bottom cut and fall into the intermediate hopper 31. In addition, the vertical electric cylinder 6 can drive the vibration motor 7 and the flexible whip 9 to lift and lower according to the number of tobacco stems in the tobacco stem pack, and whip the tobacco stem pack appropriately.

[0056] In some embodiments, the empty package recycling mechanism 4 includes a recycling vehicle 41, the left end of which is connected to the right end of the relay hopper 31, the right end of the air-blocking horizontal frame 21 is located directly above the recycling vehicle 41, and four steel rods 42 are vertically fixed to the corners of the top of the recycling vehicle 41, with barbed tips 43 threaded to the top of the four steel rods 42.

[0057] As described above, after the tobacco stems in the tobacco stem bag are emptied, the reverse-starting stretching motor 26, via the double-headed reverse screw 25, causes the front sliding plate 23 and the rear sliding plate 24 to move away from each other. At this time, the two stem bag clamps 29 holding both ends of the tobacco stem bag pull the two ends of the empty bag, causing the empty bag to stretch into a flat shape. Then, the transfer vehicle 22 moves directly above the recycling vehicle 41. At this time, the flattened empty bag moves directly above the four steel rods 42. Then, the front telescopic rod 27 and the rear telescopic rod 28 extend forward simultaneously, causing the flattened empty bag to move downward until the tops of the four steel rods 42 insert into the corners of the flattened empty bag. At this time, the stem bag clamps 29... 9. Loosen both sides of the flat empty bag, and then the front telescopic rod 27 and the rear telescopic rod 28 retract simultaneously, causing the bag clamp 29 to leave. At this time, the empty bag is fixed to the top of the steel rod 42 by the barb tip 43 and continues to be flat. Repeat this cycle, and the empty bags are gradually stacked from top to bottom until the set quantity or set weight or the empty bags touch the top surface of the recycling vehicle 41. This avoids the problem of empty bags being piled up randomly and requiring special personnel to handle them. When the four steel rods 42 are full of empty bags, the barb tip 43 connected to the thread at the top of the steel rod 42 can be unscrewed, and then the stacked empty bags can be taken out as a whole.

[0058] In some embodiments, a translation motor 5 is fixedly connected to the right end of the top of the air-level horizontal frame 21, and a main synchronous pulley 51 is fixedly connected to the output shaft of the translation motor 5. A slave synchronous pulley 52 is rotatably connected to the left end of the top of the air-level horizontal frame 21. A synchronous belt 53 is wound between the main synchronous pulley 51 and the slave synchronous pulley 52, and the bottom end of the synchronous belt 53 is fixedly connected to the top end of the transfer vehicle 22.

[0059] The translation motor 5 rotates in both directions according to the set procedure. It drives the transfer car 22 to move back and forth along the top of the open horizontal frame 21 via the synchronous belt 53. The transfer car 22 moves to the left end of the open horizontal frame 21 and grabs the full stem bag from the right end of the full stem bag conveying mechanism 1. Then, it moves to the right and passes through the unpacking and feeding mechanism 3 for unpacking and feeding. Finally, it continues to move to the empty bag recycling mechanism 4 to properly store the empty bag.

[0060] In some embodiments, guide wedges 10 are symmetrically fixedly connected to both sides of the right end of the conveyor frame 11, and the vertical height of the right end of the two guide wedges 10 is opposite to the left end of the two stalk clamps 29.

[0061] When the full bag is stopped and aligned by the lifting baffle 16 and centered by the centering clamp 20, the sewn parts on both sides of the full bag will automatically enter the open side of the left end of the guide wedge 10, and then be led out from the narrow side of the right end of the guide wedge 10. When the left ends of the two open bag clamps 29 are aligned with the right ends of the guide wedge 10, the sewn parts on both sides of the full bag will automatically enter the opening of the clamping opening of the bag clamp 29, so that the bag clamp 29 can clamp the sewn parts on both sides of the full bag when it is closed.

[0062] In some embodiments, a pressure sensor 44 is fixedly connected to the middle of the top of the recycling vehicle 41. The pressure sensor 44 is used to detect the weight of the stacked empty straw bags. After the empty straw bags are gradually stacked from the top of the steel bar 42 to its bottom, the bottom empty straw bag will press against the pressure sensor 44, and the pressure sensor 44 will sound an alarm, prompting the staff to pull away the recycling vehicle 41 full of empty straw bags and replace it with an empty recycling vehicle 41.

[0063] The automatic tobacco stem pack opening, feeding, and recycling device provided by this invention comprises a full stem pack conveying mechanism 1, a pack opening and feeding mechanism 3, and an empty pack recycling mechanism 4, arranged end-to-end. A stem pack translation mechanism 2 is positioned at the top of each of the three mechanisms. The translation mechanism 2 positions and grabs the full stem pack from the full stem pack conveying mechanism 1, then sequentially passes it through the pack opening and feeding mechanism 3 for opening and feeding. Finally, the emptied packs are neatly and orderly placed into the empty pack recycling mechanism 4 for orderly recycling, achieving efficient and automatic tobacco stem utilization and an orderly working environment. During the conveying process of full stem packs, the full stem pack conveying mechanism 1 can control the working state of the two conveyor belts through two normally closed switches, ensuring the full stem packs are aligned. Two horizontal electric cylinders 19 pull the sides of the full stem packs to center their position, facilitating the translation of the packs. Mechanism 2 positions and grabs the full tobacco stem bag; a rotating serrated blade 32 is set in the opening and feeding mechanism 3 to cut the bottom surface of the full tobacco stem bag, and a rotating combing claw 33 is set on one side of the serrated blade 32 to gradually comb the tobacco stems at the cut and drop them into the opening and feeding mechanism 3. At the same time, a vibration motor 7 is installed under the transfer car 22 to drive the flexible whip 9 to whip the top surface of the cut tobacco stem bag, so as to untangle the tobacco stems and drop them faster; after the tobacco stems in the full tobacco stem bag are emptied, the empty tobacco stem bag is first stretched into a flat shape, and then the transfer car carries the empty tobacco stem bag to the top of the empty bag recycling mechanism 4. The empty bag recycling mechanism 4 uses four steel rods 42 to insert and fix the corners of the empty tobacco stem bag, and stacks them from top to bottom, so as to achieve the purpose of standardized placement and recycling of empty packaging bags, and facilitates the staff to count the quantity.
