Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging technology, specifically to a tobacco packing and packaging workstation. Background Technology

[0002] At tobacco purchasing stations, purchased tobacco leaves are typically stored temporarily in standard transfer frames (hereinafter referred to as "tobacco frames"). When they need to be released from storage or enter the next processing stage, the tobacco leaves in the frames must be transferred to standard packaging boxes or bags. Currently, this crucial packaging process relies almost entirely on manual operation. Workers manually remove the tobacco leaves from the frames and laboriously pack them into packaging containers. This traditional operating mode has obvious drawbacks: extremely high labor intensity for workers, low work efficiency, high labor costs, and difficulty in ensuring consistent packaging quality. This has become a prominent bottleneck restricting the efficiency of tobacco leaf circulation and standardized operations. Therefore, developing equipment that can automatically complete the transfer and packaging of tobacco leaves is of great significance for improving the modernization level of tobacco purchasing stations. Utility Model Content

[0003] The purpose of this invention is to provide a tobacco leaf packing and packaging workstation to solve the aforementioned problems existing in the current tobacco leaf packaging process.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tobacco leaf packing and packaging workstation includes a frame, a tobacco frame conveying device, a tobacco frame turning mechanism, a packaging box conveying device, and a tobacco leaf pressing mechanism. The tobacco frame conveying device is located on the upper part of the frame and is used to input tobacco frames filled with tobacco leaves and output empty tobacco frames after they have been emptied. The tobacco frame turning mechanism is located on the frame and above the tobacco frame conveying device, and is used to grab and turn the tobacco frames to empty the tobacco leaves. The packaging box conveying device is located at the lower part of the frame and is used to transport empty packaging boxes to a designated workstation and receive the tobacco leaves that have fallen after being turned by the tobacco frame turning mechanism. The tobacco leaf pressing mechanism is used to press the tobacco leaves inside the packaging box after they fall into the box, thereby increasing the packaging density and reducing the volume occupied.

[0006] Furthermore, the tobacco frame conveying device includes a tobacco frame input conveyor belt and a tobacco frame output conveyor belt. The tobacco frame input conveyor belt and the tobacco frame output conveyor belt are arranged parallel to each other on the upper part of the frame, thereby forming a feeding port for unloading tobacco leaves between them. Two tobacco frame turning mechanisms are provided: the first mechanism corresponds to the end of the tobacco frame input conveyor belt and is used to turn the fully loaded tobacco frames above the feeding port; the second mechanism corresponds to the feeding port and is used to turn the empty tobacco frames after unloading and transfer them to the tobacco frame output conveyor belt.

[0007] Furthermore, the cigarette frame flipping mechanism includes a drive swing arm, a flipping frame, a cigarette frame clamping and releasing mechanism, a cover plate, and a cover plate flipping mechanism. One end of the drive swing arm is hinged to the frame, and the other end is fixedly connected to the flipping frame, for driving the flipping frame to perform a 180-degree flipping movement. The cigarette frame clamping and releasing mechanism is disposed on two opposite inner surfaces of the flipping frame, for clamping the cigarette frame before performing the flipping action and releasing the cigarette frame after the flipping is completed. Two cover plates are provided, respectively hinged to the upper two sides of the flipping frame via hinges or pivots. The cover plate flipping mechanism is connected to the cover plate, for driving the cover plate to open outward when the cigarette frame is clamped and flipped to the unloading posture, forming an unloading channel.

[0008] Furthermore, the cigarette frame clamping and releasing mechanism includes a first cylinder, a drive shaft, a mounting base, and a clamping hook. The first cylinder is fixed to the tilting frame by a bracket, and the end of its piston rod is connected to the drive shaft. The mounting base is fixed to the inner side of the tilting frame and has a vertical groove. The drive shaft passes through the vertical groove and can move up and down along the vertical groove under the drive of the first cylinder. The middle position of the clamping hook is hinged to the mounting base by a pin, allowing it to swing around the pin within a certain angle. An arc-shaped groove is formed at the upper part of the clamping hook, and the drive shaft passes through this arc-shaped groove. When the first cylinder drives the drive shaft to move up and down, the drive shaft slides in the arc-shaped groove, thereby converting linear motion into the swinging of the lower part of the clamping hook around the hinge point, realizing the clamping or releasing of the cigarette frame.

[0009] Furthermore, the cover plate flipping mechanism includes a second cylinder, a mounting plate, a drive rod, and a drive plate. The second cylinder is mounted on the side of the flipping frame via a support. The mounting plate is fixed to the edge of the flipping frame and has an elongated groove. The drive rod is fixedly connected to the rotating shaft of the cover plate, enabling the cover plate to rotate synchronously. The drive plate is fixed to the drive rod and has an inclined or arc-shaped guide groove. An output rod is connected to the piston rod end of the second cylinder, and a connecting rod is vertically mounted on the output rod. The connecting rod passes through both the elongated groove on the mounting plate and the guide groove on the drive plate. When the second cylinder extends or retracts, the output rod drives the connecting rod to move. Under the constraint of the elongated groove and the guidance of the guide groove, the connecting rod generates a compound motion, thereby driving the drive rod to rotate and realizing the opening and closing of the cover plate.

[0010] Furthermore, the tobacco leaf compaction mechanism includes a pressing block and a driving component. The pressing block is disposed at the upper end of the frame and directly opposite the feed inlet. The driving component is connected to the pressing block and is used to drive the pressing block to move downward, so that it passes through the feed inlet and compresses the loose tobacco leaves that have fallen into the packaging box below. The driving component can be a cylinder, a hydraulic cylinder, or an electric push rod.

[0011] The beneficial effects of this utility model are:

[0012] 1. High degree of automation and efficiency improvement: Through an integrated conveying, flipping and pressing system, the fully automated transfer and preliminary processing of tobacco leaves from tobacco frames to packaging boxes is realized, forming a highly efficient continuous operation line, which greatly improves packaging efficiency.

[0013] 2. Rational Layout and Optimized Space: The layout employs a double-layer design, with the upper layer for the transfer and unloading of tobacco frames and the lower layer for the conveying and receiving of packaging boxes, resulting in compact and rational space utilization. The combination of a double-tilting mechanism and double conveyor belts ensures the orderly and independent flow of fully loaded and empty tobacco frames without interference.

[0014] 3. Reliable and precise clamping and unloading mechanisms: The cigarette frame clamping and releasing mechanism, through a clever lever and groove structure, converts the linear motion of the cylinder into reliable clamping force, ensuring that the cigarette frame will not fall off during high-speed flipping. The cover plate flipping mechanism, through a linkage-groove combination, achieves smooth opening and closing of the cover plate within a limited space, ensuring smooth unloading of the tobacco leaves.

[0015] 4. Improved packaging quality: The tobacco leaf compaction mechanism can immediately compact the tobacco leaves inside the box after loading, which improves the space utilization of the packaging box, makes the tobacco leaves more stable during transportation and storage, and reduces transportation costs.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figures 1-4 As shown, the main body of the tobacco leaf packing and packaging workstation of this utility model is a sturdy frame 1. A tobacco frame conveying device 2 is installed on the upper part of the frame 1. This device consists of a tobacco frame input conveyor belt 21 and a parallel tobacco frame output conveyor belt 22. A certain distance is maintained between the two conveyor belts, forming a square discharge port 23. The tobacco frame input conveyor belt 21 is responsible for continuously conveying tobacco frames filled with tobacco leaves from the upstream process to its end station; the tobacco frame output conveyor belt 22 is responsible for transporting the empty tobacco frames away from the workstation.

[0024] On the frame 1, directly above the end of the cigarette frame input conveyor belt 21 and the discharge port 23, two identical cigarette frame tilting mechanisms 3 are installed. Figure 1 and Figure 2 As shown, the core of each cigarette frame flipping mechanism 3 is a flipping frame 32 that is driven by a drive arm 31 (which can be a hydraulic cylinder or a servo electric cylinder) to flip 180 degrees. One end of the drive arm 31 is hinged to the frame 1, and the other end is hinged to the side of the flipping frame 32. The precise positioning and flipping of the flipping frame 32 can be achieved by extending and retracting the arm.

[0025] Two sets of cigarette frame clamping and releasing mechanisms 33 are symmetrically installed on the inner side of the flipping frame 32. The working process of the mechanism is as follows: When the cigarette frame is transported to the predetermined position, the first cylinder 331 is activated, pushing the drive shaft 332 to move downward in the vertical groove 335 of the mounting base 333. Since the drive shaft 332 is also embedded in the arc-shaped groove 336 on the upper part of the clamping hook 334, its downward movement forces the clamping hook 334 to swing inward with its hinge point as the center, thus tightly holding the edge of the cigarette frame like a "hand". When released, the first cylinder 331 retracts, driving the drive shaft 332 to move upward, and the clamping hook 334 swings outward, releasing the cigarette frame.

[0026] Figures 2-4 As shown, two cover plates 34 are hinged to each other on both sides of the upper end of the flipping frame 32. The cover plates 34 are normally closed to prevent accidental spillage of tobacco leaves during non-unloading. Their opening and closing are controlled by the cover plate flipping mechanism 35. When unloading is required, the second cylinder 351 extends, pushing its output rod 357 and the connecting rod fixed thereon to move. The connecting rod passes through the elongated slot 355 on the mounting plate 352 and the guide slot 356 on the drive plate 354. The elongated slot 355 mainly serves as a guide and support, while the specific shape of the guide slot 356 (such as a diagonal line or arc) converts the linear motion of the connecting rod into the rotational motion of the drive plate 354. Since the drive plate 354 is fixedly connected to the drive rod 353, and the drive rod 353 is fixed to the pivot of the cover plate 34, the rotation of the drive rod 353 directly drives the cover plate 34 to flip open outwards. The closing process is the opposite, achieved by the retraction of the second cylinder 351.

[0027] At the lower part of the frame 1, there is a packaging box conveying device 4, which can be a stepping conveyor belt used to intermittently transport empty packaging boxes to the area directly below the feeding port 23, and send them out after they are filled with tobacco leaves.

[0028] The tobacco leaf pressing mechanism 5 is installed on top of the frame 1, with its pressing block initially positioned above the feed inlet 23. When a certain amount of tobacco leaves falls through the feed inlet 23 into the packaging box below, a drive mechanism (e.g., a long-stroke cylinder) is activated, pushing the pressing block downwards through the feed inlet 23 to vertically compress the loose tobacco leaves inside the packaging box. After pressing is complete, the pressing block rises back to its original position.

[0029] Workflow summary:

[0030] The fully loaded smoke frame is sent to the end via the smoke frame input conveyor belt 21.

[0031] The first cigarette frame flipping mechanism 3's action: Cigarette frame clamping and releasing mechanism 33 clamps the cigarette frame -> Drive swing arm 31 drives flipping frame 32 to rotate 180°, so that the cigarette frame opening faces downward and aligns with the feeding port 23 -> Cover plate flipping mechanism 35 opens the two side covers 34 -> The tobacco leaves fall into the packaging box below by gravity.

[0032] After unloading: the flip frame 32 flips back to horizontal -> the smoke frame clamping and releasing mechanism 33 releases the smoke frame, so that it temporarily falls at the discharge port 23.

[0033] The second cigarette frame flipping mechanism 3 operates as follows: it clamps the empty cigarette frame at the discharge port, flips it, and places it onto the cigarette frame output conveyor belt 22 for transport.

[0034] At the same time, the tobacco leaf pressing mechanism 5 presses the tobacco leaves in the packaging box once or multiple times.

[0035] The packaging box conveyor moves in 4 steps to one station, sending out a full and compacted packaging box and sending in the next empty packaging box.

[0036] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model are within the protection scope of this utility model.
