Description

Technical Field

[0001] This utility model relates to the field of tobacco agricultural machinery, specifically an integrated automatic separation and compaction tobacco pressing device for tobacco weaving machines. Background Technology

[0002] In modern tobacco production, automatic tobacco-binding machines are key equipment for achieving efficient and standardized tobacco leaf processing. One of its core processes involves pre-treating the specialized tobacco clips, which serve as the carrying containers, at the beginning of the binding process. A standard tobacco clip typically consists of an upper and lower clip that are mechanically snapped together. Automated tobacco binding requires first separating the closed clips, allowing the lower clip to enter the loading station to receive the tobacco leaves, while the upper clip is temporarily stored. After loading is complete, the upper clip is precisely snapped onto the fully loaded lower clip, and sufficient lateral pressure is applied to ensure a secure lock. This process of separation, temporary storage, re-closing, and compaction is fundamental to ensuring smooth subsequent binding operations and the reliability of the tobacco clips.

[0003] Currently, the industry's common solution for this technical aspect can be summarized as a "pre-separation and storage" model. Specifically, at the beginning of the cigarette-making production line, a separate cigarette clip separation pre-processing station is typically set up. Using manual labor or simple mechanical devices, all cigarette clips in a batch are pre-separated into independent upper and lower clips. The separated clips are then temporarily stored in two separate storage bins or parallel conveyor chains. When the cigarette-making machine starts operation, the control system coordinates the two feeding channels to sequentially or simultaneously retrieve the lower clip and corresponding upper clip from their respective bins and transport them to the subsequent workstations for alignment and fastening.

[0004] The existing technical solution has revealed several inherent defects in practical applications. First, it significantly increases the overall complexity and space occupation of the equipment. The independent pre-separation station, two complete silo storage systems and their supporting feeding mechanisms and positioning sensing units result in redundant equipment structure, numerous parts, and poor layout compactness, which not only increases manufacturing costs but also makes equipment installation and maintenance more difficult. Second, the process flow is artificially fragmented and lengthened, restricting production efficiency. Pre-separation, as an additional and time-consuming process, directly increases the single-cycle operation time; and the dual-silo feeding mode relies on complex electrical synchronization control logic, resulting in system response lag and difficulty in achieving precise coordination at high speeds, becoming a bottleneck for improving the overall line operating efficiency. Furthermore, the system's operational reliability faces severe challenges. The synchronization of dual-path feeding is easily disrupted by sensor drift, mechanical wear, or control signal interference, leading to disordered upper and lower cigarette clip feeding sequences or alignment failures, causing frequent jamming and downtime, and affecting the continuity of production. Furthermore, the pre-separation process and the collisions and friction within the hopper may cause cumulative wear or hidden damage to the precision snap-fit ​​mechanism of the cigarette clip, affecting its reusability and closure reliability. Finally, this solution places extremely high demands on the integration and stability of the control system, making on-site debugging, parameter optimization, and subsequent maintenance a highly technical challenge, increasing the cost of use.

[0005] Therefore, the existing "pre-separation storage" mode, due to its complex structure, lengthy process, limited efficiency, insufficient reliability, and potential damage risk to cigarette clips, is no longer able to meet the demands of modern automated cigarette-making equipment for higher efficiency, higher reliability, and simpler operation. There is an urgent need for a new type of cigarette clip processing device that can fundamentally simplify the process, integrate functions, and improve stability. Utility Model Content

[0006] In view of this, the purpose of this utility model is to propose an integrated automatic separation and compaction cigarette pressing device for cigarette weaving machines.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0018] Reference Figure 1-5 This utility model provides one embodiment: an integrated automatic separation and compaction tobacco pressing device for a tobacco weaving machine. The core of this device is a rigid frame 1 constructed from high-strength square steel pipes and steel plates, which provides a stable installation foundation and mechanical support for the entire device. The bottom of the frame 1 is typically designed with mounting holes for easy and secure fixing to the main frame of the tobacco weaving machine.

[0019] At the upper front end of frame 1, specifically at a height convenient for the operator to stand and place materials, a cigarette clip storage platform 7 is welded and fixed. The cigarette clip storage platform 7 is essentially a flat plate structure with a slight guide ramp. Its side closer to the operator is an open inlet for easy insertion of cigarette clips; its side further from the operator, facing inwards, is an open outlet directly connected to the internal processing channel. The upper surface of the cigarette clip storage platform 7 is typically covered with a layer of low-friction engineering plastic sheet to reduce resistance during the pushing process of the cigarette clips. Its main technical function is to provide a temporary, stable, and accurately positioned initial placement platform for fully closed cigarette clips, serving as the starting point for an automated feeding process.

[0020] Adjacent to the rear of the cigarette clip storage platform 7, within the internal frame of the frame 1, the cylinder body of the cigarette clip pushing cylinder 8 is securely fixed to a dedicated L-shaped steel mounting plate using four high-strength hexagonal socket bolts. This mounting plate is pre-welded to the crossbeam of the frame 1. The piston rod of the cigarette clip pushing cylinder 8 extends horizontally forward, its extension direction precisely aligned with the outlet centerline of the cigarette clip storage platform 7. At the end of the piston rod, a double-ear connector and a quick-change pin connect to the back of the main body of the cigarette pushing device 6. The cigarette pushing device 6 is a component designed to push the flat area of ​​the back of the cigarette clip. Its front working surface typically conforms to the shape of the cigarette clip and may be covered with a rubber or polyurethane cushioning layer to prevent impact damage. To ensure that the cigarette pushing device 6 maintains linear motion throughout its 125 mm pushing stroke without deflection or jamming, a linear slider is bolted to each side of the bottom of the cigarette pushing device 6. Correspondingly, two hard chrome-plated linear guides are precisely mounted parallel to the pushing direction on the upper surface of the frame 1. The two linear sliders at the bottom of the cigarette pusher 6 fit perfectly into the grooves of the two linear guide rails, forming a high-precision, low-friction linear motion pair. This cigarette pusher 6, through the sliding connection between the sliders and the horizontal guide rails on the frame 1, ensures the uniqueness and precision of the path of the cigarette clip during the pushing process, which is the key mechanical guarantee for the precise transfer of the cigarette clip from the storage position to the core work station.

[0021] The final point where the cigarette clip is pushed, i.e., the core processing station, is located in the central area inside frame 1. The primary task of this limiting station is to achieve precise spatial positioning of the cigarette clip. To this end, two thick vertical steel plates are directly welded to the left and right sides of the limiting station, forming the cigarette clip horizontal limiting device 12. The inner surfaces of these two steel plates are precision milled to ensure their parallelism and perpendicularity, and wear-resistant UHMW-PE (ultra-high molecular weight polyethylene) liners are attached to the surfaces. The gap between the two liners is precisely calculated to be slightly larger than the width of a standard cigarette clip by about 0.5 to 1 mm, forming a precise guide channel that can both guide the cigarette clip smoothly into the machine and effectively limit its lateral swaying. Its technical function is that when the cigarette pushing device 6 pushes the cigarette clip into this channel, the left and right positions of the cigarette clip are uniquely determined, eliminating the degree of freedom in the horizontal direction and providing a stable reference for subsequent separation and clamping actions.

[0022] Directly below the limiting station, at the bottom of the channel formed by the cigarette clip horizontal limiting device 12, a cigarette clip vertical limiting device 10 is installed to control the vertical position of the cigarette clip. This device is driven by a horizontally placed cigarette clip vertical limiting cylinder 9. The cigarette clip vertical limiting cylinder 9 is horizontally fixed to a support platform in the middle layer of the frame 1 by a connecting plate and bolts, with its piston rod facing forward. The end of the piston rod is threaded to a horizontally placed steel telescopic rod. In the initial state, the piston rod of the cigarette clip vertical limiting cylinder 9 is fully extended, driving the entire telescopic rod forward to its foremost position. At this time, the cigarette clip is held vertically and cannot fall. The cigarette clip vertical limiting device 10 and the cigarette clip horizontal limiting device 12 work together to complete the positioning of the cigarette clip in the X, Y, and Z directions in three-dimensional space, firmly fixing it on the preset, repeatable, and precise coordinates. This is the fundamental prerequisite for the accurate execution of all subsequent automated operations.

[0023] After precise positioning, the next step is to unlock and separate the closed cigarette clip. This function is achieved by two cigarette clip separation cylinders 11. The two cigarette clip separation cylinders 11 are symmetrically arranged on the two outer upright plates of the cigarette clip horizontal limiting device 12. Specifically, at the base of the outer side of each upright plate, an adjustable mounting bracket with an arc-shaped groove is welded. The tail of the cylinder of the cigarette clip separation cylinder 11 is hinged to this bracket via a pin, allowing the cylinder's mounting angle to be adjusted and locked within a certain range. After adjustment, the hinged seat of the cylinder is tightened with bolts. The extension direction of its piston rod precisely points to the pressing button position of the mechanical latch on the side wall of the cigarette clip. When the two cigarette clip separation cylinders 11 act simultaneously, and the piston rod extends obliquely, the pressure head precisely abuts against and presses into the latching mechanism on both sides of the cigarette clip. Due to the installation angle, this action is broken down into two components: a horizontal inward force overcomes the resistance of the latch spring, completing the mechanical unlocking; the other vertical upward force acts on the upper cigarette clip at the moment of unlocking, giving it a slight upward lifting force, creating a tiny separation gap between the upper and lower cigarette clips. This gap creates the necessary conditions for the subsequent hand-shaped cylinder 5's gripper to smoothly extend and hold the upper cigarette clip.

[0024] After the upper cigarette clip is initially lifted, it needs to be reliably clamped and removed so that the lower cigarette clip can fall. This function is accomplished by a clamping and lifting mechanism located above the frame 1. The core of this mechanism is a rectangular lifting frame. The lifting frame is connected to the frame 1 via two sets of precision ball bearing linear guides to ensure smooth movement without radial wobble. Specifically, four vertical linear guides are bolted to the reinforcing ribs at the four corners of the top of the frame 1. Four corresponding sliders are bolted to the four corners of the lifting frame. The power to drive the lifting frame to move vertically up and down comes from a cylinder 3. Cylinder 3 is a model with adjustable buffer and position sensor, and its cylinder body is fixed to the central crossbeam at the top of the frame 1 via an inverted "gate"-shaped bracket. The piston rod of cylinder 3 extends vertically downward and is connected to the crossbeam at the center of the lifting frame via a floating joint. The floating joint can compensate for a small amount of installation coaxiality error and protect the cylinder from lateral forces. At each end of the bottom crossbeam of the lifting frame, a hand-shaped cylinder 5 is vertically mounted downwards via a mounting plate. The hand-shaped cylinder 5 is a pneumatic actuator specifically designed for clamping rod-shaped or beam-shaped objects; the opening and closing of its two grippers is controlled by air pressure. Each hand-shaped cylinder 5 has an arc-shaped flexible polyurethane clamp embedded inside its gripper to increase friction and prevent damage to the paint on the upper beam of the cigarette clip. When the lifting frame descends to a predetermined height under the drive of cylinder 2 3, and the upper half of the cigarette clip has been pushed out of the gap by the separating cylinder 11, both hand-shaped cylinders 5 operate simultaneously, closing the grippers and firmly clamping the crossbeam portion of the upper half of the cigarette clip.

[0025] After the upper tobacco clip is reliably held, the lower tobacco clip needs to be released. At this time, the vertical limit cylinder 9 of the tobacco clip is activated, and the piston rod retracts. The limiting component is completely removed from the space below the tobacco clip. At this point, the lower tobacco clip loses all support and falls freely under the action of gravity. It falls accurately through the opening reserved at the bottom of the frame 1 onto the turning device or conveyor belt on the lower layer of the tobacco-making machine, and enters the subsequent tobacco leaf filling process.

[0026] Finally, when the lower half of the cigarette clip has finished loading and returned, and needs to be re-closed and locked with the upper half, the device needs to perform a compaction operation. This function is achieved by two cigarette-pressing cylinders 4. The two cigarette-pressing cylinders 4 are horizontally mounted opposite each other on the left and right sides of the frame 1. Their cylinder bodies are fixed to the strong support frame on the side of the frame 1 by heavy mounting plates. The center line of the piston rod of the cigarette-pressing cylinder 4 is strictly aligned with the side lock or the part that needs to be pressured after the cigarette clip is closed in the limit position. A flat compaction head can be installed at the end of the piston rod. When the upper and lower cigarette clips are aligned and closed, the two cigarette-pressing cylinders 4 are driven synchronously, and the piston rods extend horizontally towards the center with a large thrust, applying a balanced clamping force to the cigarette clips from both sides simultaneously. This force ensures that the mechanical lock of the cigarette clip can be fully engaged with a "click", or that some cigarette clips that rely on friction to close achieve sufficient locking, ensuring that they will not be accidentally released during subsequent lifting, flipping, and transportation. This is the final quality assurance step in the entire process.

[0027] Furthermore, to ensure that the cigarette clip does not "head-down" (i.e., the front end tilts downwards and gets stuck at the entrance) during the initial stage of being pushed from the cigarette clip storage platform 7 to the limiting station due to its forward center of gravity, an auxiliary support mechanism is installed on the frame 1 below the cigarette clip storage platform 7. This mechanism includes a cylinder 2, whose cylinder body is fixed to the lower part of the frame 1, and a piston rod extending upwards. An L-shaped support rod that can swing upwards is hinged to the end of the piston rod. At the start of the pushing action, cylinder 2 actuates first, swinging the support rod upwards to an angle so that its top precisely supports the bottom front end of the cigarette clip entering the guide channel. After most of the cigarette clip has entered the channel and the center of gravity has stabilized, cylinder 2 retracts, causing the support rod to fall down, avoiding interference with subsequent actions. This is an auxiliary design to improve the success rate.

[0028] In this embodiment, during implementation: First, the operator places a complete, locked cigarette clip horizontally on the cigarette clip storage platform 7 in a designated direction (usually with the upper half of the clip facing outwards and the lower half facing inwards). After the start signal is issued, the device enters an automatic cycle.

[0029] The first step is loading and precise positioning. Cylinder 2 activates first, driving the auxiliary support rod to swing upwards and pre-lift the cigarette clip to its designated position. Almost simultaneously, the cigarette clip pusher cylinder 8 is energized and reversed, with compressed air driving its piston rod to extend. The piston rod, through the connector, drives the cigarette pusher device 6 to move smoothly forward along the linear guide rail. The front end of the cigarette pusher device 6 contacts the back of the cigarette clip and pushes it along the slope of the cigarette clip storage platform 7 into the guide channel formed by the cigarette clip horizontal limiting device 12. The auxiliary support rod ensures that the front end of the cigarette clip does not fall or scratch during the process. Under the continuous push of the cigarette pusher device 6, the cigarette clip slides in the guide channel until its tail reaches the preset sensing position (which can be determined by a limit switch or a magnetic ring sensor built into the cylinder), at which point the cigarette clip pusher cylinder 8 stops extending. At this moment, the cigarette clip is fully constrained in six degrees of freedom (left-right, front-back, up-down), and precisely positioned at the center of the limiting station. Subsequently, cylinder 2 retracts, and the auxiliary support rod falls back to its original position; the cigarette clip pushing cylinder 8 can also begin to slowly retract, so that the cigarette pushing device 6 separates from the cigarette clip (or waits for the cycle to end before retracting).

[0030] The second step involves mechanical unlocking and gripping of the upper cigarette clip. After the cigarette clip is positioned, the control system issues a command, and the two cigarette clip separation cylinders 11 operate simultaneously. Compressed air drives their piston rods to extend rapidly along a preset tilt angle. The pressure head at the front end of the piston rod precisely strikes (or rolls) the latch buttons on both sides of the cigarette clip, overcoming the internal spring resistance and achieving mechanical unlocking. Due to the tilted installation of the cylinders, at the moment of unlocking, the pressure head generates a vertically upward component force on the upper cigarette clip, slightly lifting the rear end of the upper cigarette clip by a few millimeters, creating a clear gap between it and the lower cigarette clip. Immediately afterwards, cylinder 3 is energized, driving the lifting frame to move vertically downward along the four linear guide rails. The lifting frame descends together with the hand-shaped cylinder 5 below it. When it descends to a preset height, so that the grippers of the hand-shaped cylinder 5 are exactly on both sides of the lifted upper cigarette clip crossbeam, cylinder 3 stops. Subsequently, the two hand-shaped cylinders 5 operate simultaneously, and compressed air drives their grippers to close. The flexible clamp tightly holds the crossbeam of the upper cigarette clip, achieving reliable clamping.

[0031] The third step is to release the lower half of the cigarette clip. After the hand-shaped cylinder 5 confirms the clamping (which can be determined by a pressure sensor or a position sensor), the vertical limiting cylinder 9 of the cigarette clip actuates. Its piston rod retracts, and this action, through the internal linkage mechanism, first causes the two hook-shaped limiting components to rotate downwards to a horizontal position, releasing the support for the lower edge of the cigarette clip. Then, the entire device moves horizontally backwards, completely freeing up the space below. Having lost its lower support, the lower half of the cigarette clip falls freely under gravity, accurately dropping through the opening at the bottom of the frame into the receiving flipping device below, and entering the next cigarette loading station of the cigarette-making machine.

[0032] The fourth step is closing and final compaction. When the lower half of the tobacco clamp is filled with tobacco leaves at the loading station and returns to its precise alignment with the upper half of the tobacco clamp held above as the tobacco-making machine moves in rhythm (this alignment is coordinated by the main control system of the tobacco-making machine), the hand-type cylinder 5 receives a release command. The grippers open under the force of the spring or reverse air pressure, releasing the upper half of the tobacco clamp. The upper half of the tobacco clamp falls naturally under gravity, "sitting" on the lower half of the tobacco clamp that is already filled with tobacco leaves, completing the physical closure. Immediately afterwards, the pressing cylinders 4 on both sides of the frame start simultaneously. The two piston rods extend horizontally towards the center synchronously with a large force. The compaction heads on both sides simultaneously press against the left and right side walls of the tobacco clamp, applying a balanced, continuous pressing force for several seconds. This force ensures that the locking mechanism inside the tobacco clamp (if it is an elastic lock) is fully engaged, or that the mating surfaces of the upper and lower tobacco clamps achieve sufficient friction to complete the final process locking.

[0033] Step 5: System Reset and Preparation for the Next Cycle. After the compaction action is completed, the piston rod of the smoke-pressing cylinder 4 retracts to its reset position. Next, cylinder 3 drives the lifting frame to rise vertically, returning to its initial waiting position at the top. Simultaneously, the piston rod of the cigarette clip vertical limit cylinder 9 extends again, driving its hook-shaped limit component forward and upward, returning to the state ready to lift the next cigarette clip. The piston rod of the cigarette clip separation cylinder 11 also retracts to its reset position. Finally, the cigarette clip pushing cylinder 8 (if it has not retracted in advance) drives the cigarette pushing device 6 to return along the linear guide rail to its initial position behind the cigarette clip storage platform 7. At this point, all actuators in the device have returned to their initial state at the start of the cycle. The operator can place the next cigarette clip and start the next automatic work cycle.

[0034] This embodiment achieves full automation of the cigarette clip processing stage in the cigarette-making process through the aforementioned highly integrated structural design and precise, coordinated timing control. Its technical advantages are significant: First, it highly integrates the previously separate pre-separation station, dual-bin storage, and conveying system into a compact single workstation, greatly simplifying the mechanical structure, reducing the number of parts, lowering equipment manufacturing costs and floor space, while simultaneously improving system rigidity and reliability. Second, through precise mechanical limiting (horizontal and vertical limiting devices) and sequential pneumatic logic, it achieves continuous, rapid, and seamless connection of the entire process from cigarette clip placement to compaction, eliminating the time delays and synchronization problems caused by pre-separation and dual-path feeding, thereby significantly improving single-machine operating efficiency and overall production cycle time. Furthermore, its movements are gentle and precise; the mechanical separation and clamping method avoids the risk of cigarette clip collision and wear in the bin, and the lateral compaction is more uniform and reliable than manual operation, effectively protecting the cigarette clips and improving the consistency of the finished cigarette product. Finally, the device is highly automated, minimizing reliance on manual operation (only requiring the placement of complete cigarette clips), reducing labor intensity and skill requirements. Furthermore, the pneumatic system is easy to maintain, and the control logic is clear, significantly improving the availability and maintainability of the equipment. This provides a solid guarantee for the stable, efficient, and long-term operation of the automated cigarette making production line.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
