Description

Technical Field

[0001] The utility model relates to the technical field of tobacco packaging, in particular to a tobacco packaging mechanism. Background Art

[0002] The tobacco industry often uses tobacco bags for tobacco leaf procurement, packaging, transportation, and storage. To ensure breathability, these bags are often made of linen. Before packaging, the tobacco is compressed into blocks in a compressor, then placed into linen bags and tied with rope.

[0003] Because packaging string is relatively soft and difficult to machine-operate, most string-binding work on the market still relies on manual labor. This involves manually wrapping the string around the tobacco and then tying it in knots to complete the packaging process. However, manual tying is inefficient and slows down packaging speeds. Utility Model Content

[0004] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a tobacco packaging mechanism that automatically bundles and overlaps tobacco, thereby improving packaging efficiency and overcoming the deficiencies in the prior art.

[0010] Preferably, the second clamps are provided in two groups, and the two groups of the second clamps are spaced apart. The cutter can cut the packaging rope from the gap between the two groups of the second clamps.

[0011] Preferably, the rope winding joint device includes a rope winding fork, a third clamp, a fourth clamp, a top rope jig, and a fifth clamp; the rope winding fork can be raised and lowered and rotated; the third clamp and the top rope jig are arranged on the first side of the rope winding fork and can pull the packaging rope; the top rope jig can push the packaging rope to the fourth clamp; the fifth clamp is arranged on the second side of the rope winding fork, and the fifth clamp can press down the packaging rope.

[0012] Preferably, the rope winding fork includes a fork body, a rotating shaft, and a limit pin. The rotating shaft is arranged at a fork opening of the fork body, and the limit pin is arranged on the rotating shaft.

[0025] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0026] Please refer to Figures 1 to 5 As shown, it shows the specific structure of the preferred embodiment of the present utility model, which is a tobacco packaging mechanism.

[0027] The rope supply device 10 is used to provide packaging rope 15. The rope pulling device 20 pulls the packaging rope 15 from the rope supply device 10 to the material table 14. The rope hooking device 40 hooks the packaging rope 15 and allows the packaging rope 15 to pass through the rope loop formed by the rope knot device 30. The rope knot device 30 then knots the packaging rope 15 together, achieving automatic packaging without manual labor and improving packaging efficiency.

[0028] The present application provides a tobacco packaging mechanism, comprising a material platform 14; a rope supply device 10 disposed on a first side of the material platform 14; a rope pulling device 20, a rope winding device 30, and a rope hooking device 40 disposed on a second side of the material platform 14; the rope pulling device 20 is capable of pulling a packaging rope 15 from the rope supply device 10; the packaging rope 15 passes through the rope winding device 30, which then forms a rope knot; and the rope hooking device 40 hooks and pulls the packaging rope 15 from the rope supply device 10 through the rope knot. The material platform 14 is used to place tobacco 16. When the tobacco packaging mechanism is in operation, 1. The rope-pulling device 20 first pulls the packaging rope 15 on the rope-feeding device 10. The first section of the packaging rope 15 is pulled flat on the material table 14 by the rope-pulling device 20. The robot then places tobacco 16 on the material table 14, with the tobacco 16 pressing against the first section of the packaging rope 16. 2. Next, the rope-winding device 30 approaches the tobacco 16, forcing the first section of the packaging rope 15 into contact with the side of the tobacco 16. Subsequently, the rope-winding device 30 operates, looping around the first section of the packaging rope 15 to form a rope loop. 3. The rope-hooking device 40 hooks the second section of the packaging rope 15 on the rope-feeding device 10 (at this point, the first and second sections of the packaging rope 15 are continuous and unbroken), and passes the second section of the packaging rope through the rope loop. 4. Next, the rope-winding device 30 pulls the first section of the packaging rope 15, knotting the rope loop and the second section of the packaging rope 15 together. 5. The rope-pulling device 20 pulls a new section of the packaging rope 15, severing it. 6. The above-mentioned actions are repeated continuously. It can be seen that, with the coordinated efforts of the material platform 14, the rope-pulling device 20, the rope-winding joint device 30, and the rope-hooking device 40, the tobacco 16 is automatically bundled and packaged, achieving higher efficiency. When multiple sets of rope-feeding devices 10, rope-pulling devices 20, rope-winding joint devices 30, and rope-hooking devices 40 are arranged, multiple packaging operations can be completed in a single operation, achieving extremely high efficiency.

[0029] Preferably, the rope supply device 10 includes a rope pulley 11, a rope guide frame 12, and a first clamp 13. A packaging rope 15 is mounted on the rope pulley 11 and passes through the rope guide frame 12. The first clamp 13 is configured to clamp the packaging rope 15. The rope pulley 11 is rotatable and has the packaging rope 15 wound around it. The rope guide frame 12 is configured to control the direction of the packaging rope 15 so that it can be drawn out in a predetermined direction. The first clamp 13 is configured to clamp the packaging rope 15 and prevent it from falling. The first clamp 13 is driven by a pneumatic cylinder.

[0030] Preferably, the rope pulling device 20 includes a first linear module 21, a second clamp 22 mounted on the first linear module 21, and a cutter 24. The second clamp 22 is configured to grip the packaging rope 15 from the rope supply device 10, and the cutter 24 is configured to cut the packaging rope 15. Two sets of second clamps 22 are spaced apart, and the cutter 24 is configured to cut the packaging rope 15 in the gap between the two sets of second clamps 22. The first linear module 21 is driven by a screw and servo motor, but can also be driven by a pneumatic cylinder. The second clamp 22 is clamped or released by a second clamp cylinder 23. The second clamp 22 can move left and right, up and down, when mounted on the first linear module 21, facilitating its gripping of the packaging rope 15 from the rope supply device 10. The second clamps 22 are spaced apart, and after the cutter 24 cuts the packaging rope 15, the rope pulling device 20 can pull a new section of packaging rope 15 to the material table 14, improving work efficiency.

[0031] Preferably, the rope winding joint device 30 includes a rope winding fork 310, a third clamp 31, a fourth clamp 33, a top rope jig 320, and a fifth clamp 35. The rope winding fork 310 is capable of lifting and rotating. The third clamp 31 and the top rope jig 320 are located on the first side of the rope winding fork 310 and can pull the packaging rope 15. The top rope jig 320 can push the packaging rope 15 toward the fourth clamp 33. The fifth clamp 35 is located on the second side of the rope winding fork 310 and presses down the packaging rope 15. The rope winding fork 310 is driven to rotate by a first servo motor 312 and is raised and lowered by a rope winding fork cylinder 311. The third clamp 31 is opened and closed by a third clamp cylinder 32. The clamp head of the third clamp 31 is ring-shaped, and the packaging rope 15 can be pulled through the third clamp 31. The top rope jig 320 is driven by the top rope jig cylinder 321 to move up and down. When the top rope jig 320 rises, it can push the first section of the packaging rope 15 to the fourth clamp 33. The fourth clamp 33 is driven by the fourth clamp cylinder 34. The fourth clamp 33 is set on the linear module driven by its corresponding cylinder. The fourth clamp 33 can move up and down to facilitate pulling the knot. The fifth clamp 35 is driven by the fifth clamp cylinder 36. When the knot needs to be tightened, the fifth clamp 35 presses the packaging rope 15 on the second side of the rope fork 310 (to facilitate pulling the packaging rope to tighten the knot), and then the fourth clamp 33 pulls the first section of the packaging rope 15, so that the knot can be tied, so that the packaging rope 15 firmly binds the tobacco 16.

[0032] Preferably, the rope winding fork 310 includes a fork body 313, a rotating shaft 315, and a limiting pin 316. The rotating shaft 315 is disposed at a fork opening 314 of the fork body 313, and the limiting pin 316 is disposed at the rotating shaft 315. The rotating shaft 315 can rotate on the fork body 313, and the limiting pin 316 separates the fork opening 314, which facilitates controlling the position of the packaging rope 15 so that the rope winding fork 310 can wind the packaging rope 15 into a rope buckle.

[0033] Preferably, the top rope jig 320 is provided with a clearance opening 322, and the head of the top rope jig 320 is provided with a positioning opening 323 for clamping the packaging rope 15. The fourth clamp 33 clamps the packaging rope 15 through the clearance opening 322. The clearance opening 322 allows the fourth clamp 33 to extend into the top rope jig 320 when the top rope jig 320 is raised, thereby facilitating the clamping of the packaging rope 15. The positioning opening 323 prevents the packaging rope 15 from slipping, facilitating the fourth clamp 33 to clamp the packaging rope 15.

[0034] Preferably, the rope winding joint device 30 further includes a liftable rope pushing plate 37, through which the rope winding fork 310 passes. The rope pushing plate 37 is driven up and down by a pneumatic cylinder. The rope pushing plate 37 facilitates the withdrawal of the tied packaging rope 15 from the rope winding fork 310, thereby achieving more coordinated movement.

[0035] Preferably, the rope hooking device 40 includes a second linear module 41 and a rope hook 43 disposed on the second linear module 41. The rope hook 43 is rotatable, and the first end of the rope hook 43 has a hook portion for hooking the packaging rope 15. The second linear module 41 is driven by a screw and a servo motor, but can also be driven by a cylinder. The rope hook 43 is rotated by a second servo motor 42. The second linear module 41 drives the rope hook 43 back and forth. The rotatable rope hook 43 facilitates hooking and lowering the packaging rope 15.

[0036] Preferably, the hook portion is provided with a guide wheel 44 and a tapered portion 45. The guide wheel 44 facilitates the hook portion to hook the packing rope 15. The tapered portion 45 facilitates the tapered portion 45 to pass through the rope buckle.

[0037] The specific working steps are as follows: 1. The packaging rope 15 comes out from the rope wheel 11, and then passes through the rope guide frame 12. The first clamp 13 clamps the rope end of the packaging rope 15 to prevent the packaging rope 15 from being withdrawn or falling, making it convenient for subsequent clamping. 2. The first linear module 21 drives the second clamp 22 to move toward the rope supply device 10, and the second clamp 22 clamps the rope end of the first section of the packaging rope 15; then the first linear module 21 drives the second clamp 22 to reset, and at this time the first section of the packaging rope 15 will be flat on the material table 14, and will pass through the rope winding fork 310. 3. Place the tobacco 16 on the material table 14, and the tobacco 16 presses the first packaging rope 15 on the material table 14. 4. The rope end of the first packaging bag is clamped by the second clamp 22, and the rope winding node device 30 moves closer to the tobacco 16; the rope winding fork 310 rises and presses against the position near the rope end of the first packaging rope 15, and then the third clamp 31 pulls down the position near the rope end of the first packaging rope 15; then the rope is rotated at least one circle, so that a rope buckle will be formed near the rope end of the first packaging rope 15. 5. The second linear module 41 drives the rope hook 43 toward the rope supply device 10. The rope hook 43 hooks the end of the second strand of packaging rope 15 (the first and second strands of packaging rope 15 are unbroken) and retracts, causing the second strand of packaging rope 15 to fall onto the tobacco 16 and pass through the first strand of rope buckle on the rope winding fork 310. 6. The rope hook 43 hooks the second strand of packaging rope 15, forming a second strand of rope buckle. The rope hook 43 rotates, causing the second strand of packaging rope 15 to be horizontal. The rope lifting fixture 320 then lifts the first strand of packaging rope 15 near its end toward the fourth clamp 33, which clamps the first strand of packaging rope 15. 7. The rope winding is rotated and reset, facilitating the release of the first strand of rope buckle. The rope push plate 37 pushes upward, and the fifth clamp 35 presses the packaging ropes 15 together, thereby firmly holding both the first and second strands of packaging rope 15 on the second side of the rope winding fork 310. 8. The fourth clamp 33 continues to pull the first wrapping string 15 upward near its end, thus tying both wrapping strings 15 to the tobacco 16. 9. The fifth clamp 35 is released, and the second clamp 22 of the string-pulling device 20 releases the end of the first wrapping string 15. The fifth clamp 35 is released, and the string-pulling device 20 moves a certain distance toward the string-feeding device 10. The two second clamps 22 then clamp the next wrapping string 15 emerging from the second wrapping string 15 (i.e., the first wrapping string 15 for the subsequent tobacco 16 bundle), and the cutter 24 then cuts this next wrapping string 15. 10. One of the second clamps 22 continues to pull a new wrapping string 15, and the entire process repeats.

[0038] In summary, the key design feature of the present invention lies in the coordinated operation of the material platform 14, the rope supply device 10, the rope pull device 20, the rope winding joint device 30, and the rope hook device 40 to achieve fully automatic bundling and packaging of tobacco 16, eliminating the need for manual operation and improving work efficiency. When a single material platform 14 is used with multiple sets of rope supply devices 10, rope pull devices 20, rope winding joint devices 30, and rope hook devices 40, multiple rope knots can be bundled and packaged simultaneously, achieving even higher work efficiency.
