[0002] In the tobacco industry, cigarette frames are specialized containers used for loading, transporting, and storing tobacco products. They are generally made of metal or high-strength plastic and have specific shapes and structures to meet the needs of tobacco production, warehousing, and logistics.
[0003] A search revealed that the publication (announcement) number CN222408737U discloses "a tobacco frame conveying device, belonging to the field of conveying equipment technology, including a support frame, with a conveying device at the bottom of the support frame... This utility model, by setting up a conveying device, with a chain drive on the conveying device, when the tobacco frame filled with tobacco leaves is pushed to the conveying device, the conveying device directly conveys the tobacco frame to the baling machine for fixing via the chain. The baling machine weighs, compacts, and bales the tobacco leaves in the tobacco frame, improving work efficiency and reducing labor intensity; a guide rail is set above the conveying device, with rollers installed on the guide rail to guide the tobacco frame, making the tobacco frame more stable during the conveying process." However, the distance between the two guide rails in this application is fixed, thus it is not suitable for use with tobacco frames of different sizes, reducing the applicability of the device.
[0004] To address the aforementioned issues, this application provides an automatic locking track for cigarette frames. Utility Model Content

[0024] Example:
[0025] Please see Figure 1 , Figure 2 and Figure 3, an embodiment of the present application discloses an automatic locking track for a cigarette box, which includes a support base 1 and two connecting members 2 symmetrically and fixedly connected to the left end face of the support base 1. The support base 1 is fixed to the packing machine through the two connecting members 2. The top of the support base 1 is symmetrically provided with sliding grooves 4. Two sliders 5 are symmetrically and slidably connected inside the sliding grooves 4. A bidirectional screw rod 6 is rotatably connected inside the sliding groove 4 near the left end of the support base 1. The two sliders 5 are symmetrically threadedly sleeved outside the bidirectional screw rod 6. And a first motor 7 for driving the bidirectional screw rod 6 to rotate is fixedly connected to the outside of the support base 1. The second motor 11 works to drive the insertion rod 10 to rotate, thereby带动 the sprocket 16 on the left front side to rotate. And the rotation of the insertion rod 10带动 the limiting tube 9 to rotate, and the rotation of the limiting tube 9带动 the sprocket 16 on the left rear side to rotate. The rotation of the two sprockets 16带动 the chain 12 to rotate, and the rotation of the chain 12 directly conveys the cigarette box into the packing machine for fixation. The first motor 7 works to drive the bidirectional screw rod 6 to rotate, and the rotation of the bidirectional screw rod 6 drives the two sliders 5 inside the sliding groove 4 to move relatively or move towards each other, thereby带动 the two chains 12 and the two limiting components 3 to move relatively or move towards each other, so as to adjust the distance between the two chains 12 and the two limiting components 3 to adapt to the use of cigarette boxes of different sizes, improving the applicability of the device. Among them, when the two chains 12 move relatively or move towards each other, the insertion rod 10 moves inside the limiting tube 9. Two fixing plates 8 are provided on the slider 5. Two sprockets 16 are symmetrically and rotatably connected between the two fixing plates 8. The two sprockets 16 on the front and rear sides above the support base 1 are both connected by a chain 12. A cigarette box (not shown in the figure) is provided on the right side of the top of the two chains 12. The chain 12 is arranged between two adjacent fixing plates 8. Among them, circular holes are symmetrically opened on three fixing plates 8. A hexagonal hole one is opened in the middle of two sprockets 16, and a hexagonal hole two is opened in the middle of the other two sprockets 16. The inner wall of the hexagonal hole one is fixedly connected with a limiting tube 9, and the inner wall of the hexagonal hole two is fixedly connected with an insertion rod 10. The insertion rod 10 is arranged in a hexagonal shape structure. A second motor 11 for driving the insertion rod 10 to rotate is fixedly connected to the surface of the fixing plate 8 near the front side of the support base 1. Limiting components 3 are arranged on the surfaces of the fixing plates 8 near the front and rear sides of the support base 1.
[0026] Please refer to Figure 2 and Figure 3 , the slider 5 is arranged in a "convex" shape structure, so as to limit the slider 5 to be slidably connected inside the sliding groove 4. An installation groove 51 is opened at the top of the slider 5. The two adjacent fixing plates 8 are fixedly connected to the inner wall of the installation groove 51. Two fixing columns 13 are symmetrically arranged between the two adjacent fixing plates 8. On the basis of fixing the two adjacent fixing plates 8 by using the slider 5, the two fixing plates 8 are further fixedly connected by using the fixing columns 13, thereby improving the stability of the two adjacent fixing plates 8. And the two ends of the fixing column 13 are respectively fixedly connected to the opposite side surfaces of the two adjacent fixing plates 8.
[0027] Please see Figure 1 The end of the limiting tube 9 away from the sprocket 16 passes through the round hole and extends to the outside of the fixing plate 8. The end of the insertion rod 10 away from the sprocket 16 passes through the round hole and is slidably inserted into the inside of the limiting tube 9. An arc-shaped plate is fixedly connected to the surface of the fixing plate 8 near the front side of the support base 1. The second motor 11 is fixedly connected to the inner wall of the arc-shaped plate. The output end of the second motor 11 passes through the round hole and is fixedly connected to the front end of the insertion rod 10.
[0028] Please see Figure 2 Two adjacent fixed plates 8 have symmetrically formed annular grooves 14 on their opposite sides. Annular plates 15 are rotatably connected inside the two adjacent annular grooves 14. The opposite sides of the two adjacent annular plates 15 are fixedly connected to the two sides of the sprocket 16. The annular plates 15, in conjunction with the annular grooves 14, rotatably connect the sprocket 16 between the two adjacent fixed plates 8. When the sprocket 16 rotates, the sprocket 16 drives the annular plates 15 to rotate inside the annular grooves 14, which improves the stability of the sprocket 16 when it rotates.
[0029] Please see Figure 1 The limiting component 3 includes two connecting posts 31 fixedly connected to the surface of the fixed plate 8. A vertical plate 32 is fixedly connected to the connecting posts 31. A guide rail 34 is fixedly connected to the top of the vertical plate 32. Multiple rollers 33 are installed on the guide rail 34. The multiple rollers 33 on the guide rail 34 play the role of limiting the cigarette frame and guiding the cigarette frame, so that the cigarette frame is more stable during the conveying process.
[0030] Please see Figure 1 A support rod 17 is fixedly connected to the top right side of the support base 1, and an electromagnet 18 is fixedly connected to the top of the support rod 17. An iron plate is fixedly connected to the bottom of the tobacco frame. The tobacco frame is placed on the top right side of the two chains 12, so that the iron plate at the bottom of the tobacco frame is located on top of the electromagnet 18. The electromagnet 18 is energized to attract and fix the iron plate, thereby achieving automatic locking of the tobacco frame. This ensures that the tobacco frame remains stable in a stationary state and prevents the tobacco frame from shifting when loading tobacco leaves. Then, the tobacco leaves are loaded into the locked tobacco frame.
[0031] The implementation principle of this application embodiment is as follows: the support base 1 is fixed to the baling machine by two connecting parts 2, the first motor 7 is controlled to drive the bidirectional lead screw 6 to rotate, the bidirectional lead screw 6 rotates and drives the two sliders 5 inside the slide groove 4 to move relative to each other or towards each other, thereby driving the two chains 12 and the two limiting components 3 to move relative to each other or towards each other, thereby adjusting the distance between the two chains 12 and the two limiting components 3 so that the distance between the two limiting components 3 is adapted to the size of the cigarette frame. Then the cigarette frame is placed on the top right side of the two chains 12, so that the iron plate at the bottom of the cigarette frame is located on the top of the electromagnet 18, so that the electromagnet 18 is energized to attract and fix the iron plate, thereby realizing automatic locking of the cigarette frame, ensuring that the cigarette frame remains stable in a static state, and preventing the cigarette frame from shifting when loading tobacco leaves. Then the tobacco leaves are loaded into the locked cigarette frame.
[0032] The second motor 11 drives the insertion rod 10 to rotate, which in turn drives the sprocket 16 on the left front side to rotate. The rotation of the insertion rod 10 drives the limit tube 9 to rotate, and the rotation of the limit tube 9 drives the sprocket 16 on the left rear side to rotate. The rotation of the two sprockets 16 drives the chain 12 to rotate. The rotation of the chain 12 directly transports the cigarette frame to the baler for fixing. During the cigarette frame transport process, the multiple rollers 33 on the guide rail 34 play a role in limiting the cigarette frame and guiding the cigarette frame, making the cigarette frame more stable during the transport process.
