Description

Technical Field

[0001] This invention relates to the field of counting and packaging equipment technology, and in particular to a columnar sealing plug counting and packaging equipment. Background Technology

[0002] As a core component in automobile manufacturing, hydraulic systems, pipeline engineering, and general machinery assembly, cylindrical sealing plugs encompass various types, including rubber plugs, plastic plugs, and metal screw plugs. In large-scale industrial production, they must be packaged in precise quantities, such as 100 or 500 pieces per package, to meet the rigid requirements of production line material supply, accurate inventory management, and cost accounting. Currently, the industry commonly uses manual counting and packaging methods or semi-automatic counting equipment based on vibratory feeders and photoelectric sensors. However, both methods suffer from deep-seated technical defects, severely restricting production efficiency and product quality. Manual counting and packaging rely entirely on operators visually counting and manually placing the plugs into bags. Due to the highly similar shape of the cylindrical sealing plugs and the large workload, operators are prone to visual fatigue and distraction during long periods of repetitive visual counting, leading to frequent counting errors. Especially when dealing with small-sized or similarly colored sealing plugs, even slight visual deviations can cause inaccurate batch packaging quantities, resulting in a chain reaction of problems such as material shortages and unplanned downtime on the production line. At the same time, distorted inventory data will directly disrupt the cost accounting system. In addition, direct contact between hands and sealing plugs during manual operation inevitably introduces contaminants such as dust and grease. For sealing plugs with strict cleanliness requirements (such as components used in medical equipment or precision instruments), this will significantly damage their sealing performance and service life. While semi-automatic counting equipment based on vibratory feeders and photoelectric sensors attempts to improve efficiency, it faces the fundamental challenge of uncontrollable material posture. Due to the cylindrical geometry, cylindrical sealing plugs are prone to rolling, tilting, or random flipping on horizontal conveyor belts, making it impossible to maintain a single, stable detection posture for the photoelectric sensor. When oil stains or static electricity adhere to the sealing plug surface, multiple plugs often stick together, stack, or partially obstruct each other, causing the photoelectric sensor to fail to identify parts within its field of view, frequently resulting in missed or over-counting. For example, in high-speed production line environments, the dense arrangement of sealing plugs often causes the sensor to misjudge them as a continuous whole, resulting in severely distorted counting results. Simultaneously, the equipment suffers from a severe lack of flexibility: the vibratory feeder track and conveyor system are customized for sealing plugs of specific sizes and materials. When product specifications change (such as diameter, length, or material differences), the machine must be stopped to adjust parameters such as track width and vibration frequency, and even replace specialized parts. This not only extends the equipment debugging cycle but also significantly reduces the production line's adaptability to multi-variety, small-batch production. The aforementioned problems collectively result in systemic deficiencies in the existing technology regarding counting accuracy, operational continuity, and equipment flexibility, making it difficult to meet the urgent needs of modern industry for efficient and reliable packaging processes.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] Please see the appendix Figure 1-6 This embodiment describes a columnar sealing plug counting packaging device.

[0032] The equipment includes a frame 1, which serves as the skeleton of the entire equipment, supporting and securing all functional components. For example, the frame 1 can be constructed from welded steel structures or bolted aluminum profiles, and its strength and stability must meet the load requirements during equipment operation.

[0033] The storage hopper 2 is fixedly connected to the frame 1 and is used to store the columnar sealing plugs to be processed. The storage hopper 2 can be a simple funnel-shaped container. A conveyor belt 3 is provided below the storage hopper 2 to transport the material out of the storage hopper 2. The conveyor belt 3 can be a flat belt or chain plate belt driven by a motor, and its speed can be manually adjusted by a frequency converter to adapt to the conveying requirements of different materials.

[0034] The discharge end of the conveyor belt 3 is equipped with an adjusting plate 4, which is hinged to the storage hopper 2. The adjusting plate 4 can be a rotatable baffle, and its angle or position can be manually adjusted to control the amount of material carried out from above the conveyor belt 3, thereby preventing the material from being piled up too thickly on the conveyor belt 3.

[0035] A linear vibrator 5 is provided on the side of the adjusting plate 4, and a material dispersing assembly 6 is provided on the linear vibrator 5. The linear vibrator 5 can be a vibrating trough driven by an electromagnetic vibrator, and its vibration frequency and amplitude can be manually adjusted so that the material is initially dispersed before entering the material dispersing assembly 6.

[0036] The bulk material assembly 6 is a key component for achieving precise material attitude control, and it is fitted with a counting trough 7 below it. The bulk material assembly 6 can be composed of multiple guide plates and baffles, which guide the material into the preset channel through its own gravity or vibration.

[0037] The bulk material assembly 6 includes a flow divider plate 601, on which a bulk material baffle plate 602 is provided. Both the bulk material baffle plate 602 and the flow divider plate 601 have a separating groove 603. The flow divider plate 601 can be a plate-like structure with an inclined surface for guiding materials. The bulk material baffle plate 602 can be several baffles fixed to the flow divider plate 601 for further guiding and restricting the movement of materials. The distance between the bulk material baffle and the flow divider plate 601 is less than twice the maximum diameter of the sealing plug, so that when the sealing plug passes through the gap, stacked sealing plugs can be separated, preventing the stacked sealing plugs from affecting the counting. The separating groove 603 is the core of the bulk material assembly 6 and is designed as a regular triangular prism structure. The maximum diameter cross-section of the sealing plug is tangent to the transverse cross-section of the partition groove 603. This design forces the columnar sealing plug into a single, stable posture as it passes through the partition groove 603. The sealing plug is placed obliquely within the partition groove 603. When it enters the counting groove 7, its state changes. For example, the slender part falls into the counting groove 7 under gravity, while the protruding part gets stuck in the counting groove 7, thus ensuring that each sealing plug enters the counting area in the same identifiable posture. The counting groove 7 is located at the end of the partition groove 603, and its length is the same as the length of the sealing plug. This constraint ensures that whether the slender part of the sealing plug enters the counting groove 7 first, or the wider part of the sealing plug enters the counting groove 7 first, the slender part below it will always fall into the counting groove 7 before leaving it. This allows the counting sensor 8 located on the side of the counting groove 7 to count accurately. The transverse width of the counting groove 7 is equal to the minimum diameter of the sealing plug, further ensuring the accurate accommodation and positioning of individual sealing plugs.

[0038] A counting sensor 8 is provided on the side of the counting slot 7. This counting sensor 8 is used to detect the number of sealing plugs in the counting slot 7. The counting sensor 8 can be a photoelectric sensor or a proximity switch. When a sealing plug enters the counting slot 7 and is correctly placed, the sensor sends a signal to complete one count.

[0039] The counting trough 7 has a feeding hopper 9 on its side, and two sets of symmetrically distributed feeding pipes 10 are connected below the feeding hopper 9. The feeding hopper 9 can be a collection container for temporarily storing the counted sealing plugs. The two sets of feeding pipes 10 can be connected to different packaging stations to achieve continuous or alternating packaging.

[0040] A pipe baffle 11 is provided between the two sets of discharge pipes 10, and the pipe baffle 11 is rotatably connected to the discharge hopper 9. The pipe baffle 11 can be a rotatable plate structure, which can be manually or by a simple actuator to select which discharge pipe 10 to feed material into, or to temporarily block all discharge.

[0041] A material discharge baffle 12 is slidably connected inside the discharge hopper 9, and the material discharge baffle 12 is located in front of the counting trough 7. The material discharge baffle 12 can be a vertically sliding plate that moves synchronously with the pipe baffle 11. When the pipe baffle 11 changes the material discharge pipe 10 of the sealing plug, the material discharge baffle 12 rises synchronously to briefly stop the material discharge, thereby controlling when the sealing plug in the counting trough 7 falls into the discharge hopper 9.

[0042] The pipe baffle 11 and the discharge baffle 12 move synchronously to ensure the coordination of the material discharge process. For example, when the discharge baffle 12 opens to allow the material to fall into the discharge hopper 9, the pipe baffle 11 simultaneously rotates to a preset position, guiding the material to the target discharge pipe 10. This synchronous movement can be achieved through a simple mechanical linkage mechanism.

[0043] Both sets of feeding pipes 10 are fitted with packaging components 13 on their outer sides. The packaging component 13 can be a simple manual bagging device, in which the operator places the packaging bag over the outlet of the feeding pipe 10 and then manually seals it.

[0044] The following example will provide a more detailed explanation of the above technical solution: Imagine a factory producing cylindrical sealing plugs that needs to precisely package a large quantity of plugs into bundles of 100. Traditional manual counting methods are inefficient and prone to errors, while semi-automatic equipment based on vibratory feeders often results in missed or over-counted counts due to the unstable posture of the sealing plugs.

[0045] At this point, the columnar sealing plug counting and packaging equipment provided in this embodiment can be used. First, a large number of columnar sealing plugs are poured into the storage hopper 2 of the equipment. At the bottom opening of the storage hopper 2, the adjusting plate 4 is manually adjusted to a suitable angle so that the sealing plugs on the conveyor belt 3 are transported outwards while remaining as flat as possible (without stacking). The conveyor belt 3 transports the sealing plugs to the linear vibrator 5 at a preset speed.

[0046] The linear vibrator 5 begins to vibrate, initially dispersing the sealing plugs on the conveyor belt 3 before they enter the bulk material assembly 6, reducing stacking. These initially dispersed sealing plugs are then guided to the bulk material assembly 6. In the bulk material assembly 6, the diverter plate 601 and the bulk material baffle plate 602 work together to further guide the sealing plugs to the separator trough 603. The separator trough 603 is designed as a regular triangular prism structure, with its transverse section tangent to the maximum diameter section of the sealing plug. The sealing plug moves obliquely within the separator trough 603. As it passes through, its slender portion sinks naturally under gravity and falls into the counting trough 7 below, while the protruding portion of the sealing plug is held in place by the edge of the separator trough 603, ensuring that each sealing plug is precisely placed in the counting trough 7 with a single, stable, vertical orientation. The length of the counting trough 7 is the same as the length of the sealing plug, and its transverse width is equal to the minimum diameter of the sealing plug, further guaranteeing the uniqueness and stability of each sealing plug within the counting trough 7.

[0047] When a sealing plug is correctly placed in the counting slot 7, the counting sensor 8 located on the side of the counting slot 7 immediately detects its presence and sends a counting signal to the control system. One sealing plug is held in each counting slot 7 at a time. After being counted, the sealing plug falls into the discharge hopper 9 and then passes through one of the discharge pipes 10 into the packaging assembly 13. The control system accumulates the count, and when a preset quantity of 100 pieces is reached, the control system issues a command. At this time, the discharge baffle 12 in the discharge hopper 9 is driven upwards, blocking the side of the discharge slot. Simultaneously, the pipe baffle 11 also rotates synchronously, guiding the material to another discharge pipe 10. For example, if packaging is currently being done using the left discharge pipe 10, the pipe baffle 11 will rotate to guide the material to the right discharge pipe 10, while the discharge baffle 12 resets.

[0048] The sealing plugs enter the packaging assembly 13 below through the feed pipe 10. At the packaging assembly 13, the operator places a packaging bag over the outlet of the feed pipe 10, and the sealing plugs fall into the bag. Once all 100 sealing plugs have fallen into the packaging bag, the packaging assembly 13 completes the packaging. The operator then removes the packaged sealing plugs and prepares for the next packaging bag. Subsequently, the equipment continues counting and packaging the next batch of sealing plugs. In this way, the equipment achieves automated, high-precision, and continuous counting and packaging of cylindrical sealing plugs.

[0049] The drive rollers rotatably connected to both ends of the conveyor belt 3, through their rotational connection with the frame 1, provide a stable driving force for the conveyor belt 3, ensuring that materials can be continuously and smoothly conveyed from the storage hopper 2 to the bulk material assembly 6. Simultaneously, the conveyor guards 14 on both sides of the conveyor belt 3 and the separating plate effectively restrict the lateral movement of materials during the conveying process, preventing material scattering or deviation from the predetermined path, thereby ensuring the integrity and directionality of material conveying. Furthermore, the first adjusting screw 15 threaded onto the conveyor guard 14 is rotatably connected to the bulk material baffle 602, allowing for precise fine-tuning of the position of the bulk material baffle 602. When materials enter the bulk material assembly 6 from the conveyor belt 3, adjusting the position of the bulk material baffle 602 allows for precise control of the material flow rate and distribution uniformity, ensuring that the materials enter the separating trough 603 in optimal condition for dispersing and counting. This synergistic effect ensures the stability, efficiency, and controllability of the entire conveying and initial diversion process of materials from the storage hopper 2 to the bulk material assembly 6, laying the foundation for subsequent accurate counting and packaging. The drive rollers at both ends of the conveyor belt 3 can be steel rollers with a surface covered with wear-resistant rubber. They are rotatably connected to the frame 1 via bearing seats and driven by a servo motor to achieve precise speed control of the conveyor belt 3. The conveyor guard plates 14 on both sides of the conveyor belt 3 and the separation plate can be made of 2mm thick stainless steel plates and are fixed to the side wall of the frame 1 by welding or bolting. Their height is designed to be slightly higher than the height of the columnar sealing plug to effectively prevent material overflow. The first adjusting screw 15 can be a trapezoidal threaded rod with a fine pitch. One end of it passes through a pre-set threaded hole on the conveyor guard plate 14, and the other end is rotatably connected to the side of the bulk material baffle 602 via a connector with a pin. By manually rotating the handwheel on the first adjusting screw 15, the bulk material baffle 602 can be slightly displaced in the horizontal direction, thereby precisely adjusting the opening width for material to enter the bulk material assembly 6.

[0050] The linear vibrator 5 includes a vibration source 501, to which a housing 502 is fixedly connected. An elastic element 503 is installed between the housing 502 and the frame 1. The housing 502 is fixedly connected to the diversion plate 601, which includes horizontal deceleration zones at both ends and a middle inclined downward feeding zone. When the vibration source 501 is activated, the resulting vibration is transmitted to the diversion plate 601 through the fixedly connected housing 502. To prevent the vibration from being directly transmitted to the entire frame 1, the elastic element 503 installed between the housing 502 and the frame 1 effectively absorbs and isolates most of the vibration energy, ensuring the stable operation of the entire equipment and avoiding the impact on the accuracy of subsequent counting and packaging due to excessive vibration. The diversion plate 601, as the material bearing surface, has a particularly important structural design. The material first enters the horizontal deceleration zones at both ends of the diversion plate 601. In this area, the material speed is smoothly adjusted, avoiding impact and accumulation. Subsequently, under the action of vibration, the material smoothly transitions from the horizontal deceleration zones to the middle inclined downward feeding zone. In the sloping downward feeding zone, the inclined design of the diverter plate 601, combined with vibration, allows the material to flow downwards evenly and orderly and gradually disperse under the dual action of gravity and vibration. This design ensures that the material has undergone preliminary homogenization before entering the bulk material assembly 6, laying the foundation for the subsequent precise diversion of the bulk material assembly 6 and the accurate filling of the counting tank 7.

[0051] The direct vibration transducer 5 can be configured as follows: the vibration source 501 uses two symmetrically arranged electromagnetic vibrators, which are fixed to the bottom of the housing 502 by bolts. The housing 502 can be welded from a 3mm thick stainless steel plate to form a U-shaped groove structure with its opening facing upwards to support the diverter plate 601. At the four corners of the housing 502, cylindrical helical springs are installed as elastic elements 503. The lower ends of these springs are fixed to the support base of the frame 1, and the upper ends are connected to the housing 502, thereby supporting and suspending the housing 502. The diverter plate 601 is firmly fixed to the upper part of the housing 502 by welding or bolting. The horizontal deceleration zone of the diverter plate 601 can be designed as a flat area with a length of about 100mm, located at both ends of the diverter plate 601. The middle inclined downward feeding zone can be designed as a length of about 300mm with an inclination angle of about 5 degrees to ensure that the sealing plug can move smoothly towards the bulk material assembly 6 and initially disperse under the action of vibration.

[0052] The direct-vibration transducer 5 effectively controls the flow state of materials during the conveying and distributing of the columnar sealing plugs. The cooperation between the vibration source 501, the housing 502, and the elastic element 503 achieves effective transmission and isolation of vibration energy, significantly reducing the impact of vibration on the entire equipment frame 1, thereby improving the operational stability of the equipment and reducing noise. The horizontal deceleration zone and the inclined downward feeding zone set on the diversion plate 601 allow the material to undergo a smooth acceleration, deceleration, and distribution process before entering the bulk material assembly 6, avoiding material accumulation, jumping, or uneven distribution. This ensures that the material enters the subsequent counting tank 7 in a more uniform and orderly manner, thereby improving counting accuracy and packaging efficiency. This design optimizes the material pretreatment process, providing a solid foundation for the accurate and efficient operation of the entire counting and packaging equipment.

[0053] The adjusting plate 4 is hinged to the connecting rod 16, which in turn is hinged to the adjusting block 17, thus converting the rotational motion of the adjusting plate 4 into the linear motion of the adjusting block 17. A second adjusting screw 18 is fixedly connected to the adjusting block 17, and the second adjusting screw 18 slides within the guide block 19. A limit nut 20 is threaded onto the second adjusting screw 18, and a first spring 21 is provided between the limit nut 20 and the guide block 19 below the guide block 19. When it is necessary to adjust the position of the adjusting plate 4, the limit nut 20 can be rotated to move along the thread of the second adjusting screw 18. The movement of the limit nut 20 will cause the second adjusting screw 18 to slide within the guide block 19, thereby changing the hinge angle of the adjusting plate 4 through the action of the adjusting block 17 and the connecting rod 16. The presence of the first spring 21 provides an elastic support between the limiting nut 20 and the guide block 19, allowing the second adjusting screw 18 to have an elastic reserve for upward sliding relative to the guide block 19. When the adjusting baffle exerts excessive pressure on the sealing plug inside the storage hopper 2, to avoid excessive external force on the sealing plug, the adjusting baffle will swing upward appropriately, increasing the opening of the discharge end of the conveyor belt 3, and preventing the internal parts from receiving excessive pressure than the sealing plug, thereby ensuring the accuracy and stability of the adjusting plate 4 in the set position. This linkage mechanism allows the operator to achieve precise control of the opening angle of the adjusting plate 4 through simple rotation, thereby accurately adjusting the discharge flow rate of the material.

[0054] One specific embodiment is as follows: The adjusting plate 4 can be a metal plate, with its upper edge hinged to the storage hopper 2 via a pin. A connecting rod 16, such as a rigid metal rod, has one end hinged to the lower side of the adjusting plate 4 via a pin, and the other end hinged to an adjusting block 17 via a pin. The adjusting block 17 can be a cube with a through hole, through which a guide rod 24 passes and is fixed to the adjusting block 17. A guide block 19 is fixedly installed on the side wall of the storage hopper 2, and the guide block 19 can be a hollow sleeve. The second adjusting screw 18 is machined with external threads, and a compression spring, as the first spring 21, is disposed between the lower end face of the guide block 19 and the upper end face of the limiting nut 20. When the operator rotates the limiting nut 20 above the guide block 19, the limiting nut 20 will move up or down along the thread of the second adjusting screw 18. The movement of the limiting nut 20 will cause the second adjusting screw 18 to slide in the inner hole of the guide block 19. Thus, through the linkage of the adjusting block 17 and the connecting rod 16, the adjusting plate 4 will rotate around its hinge axis, changing its opening angle and achieving precise adjustment of the material flow rate.

[0055] A reciprocating oscillating sector block 22 is rotatably connected to the frame 1. The sector block 22 is coaxially and fixedly connected to the pipe baffle 11. An arc-shaped protrusion 23 is fixedly connected to the upper end of the sector block 22. A guide rod 24 is fitted above the protrusion 23. The guide rod 24 is fixedly connected to the discharge baffle 12. The discharge hopper 9 is provided with a first sliding groove 25 for the guide rod 24 to slide. A reset assembly 26 is provided between the discharge hopper 9 and the discharge baffle 12. The sector block 22 is a mechanical component with a specific arc shape, which usually reciprocates around a central axis. Its function is to drive other components through its oscillating motion to achieve mechanical linkage or control. For example, the sector block 22 can be driven by a motor, driven by a linkage 16 mechanism, or achieve a preset trajectory movement through a cam mechanism. The coaxial fixed connection of the pipe baffle 11 means that the sector block 22 and the pipe baffle 11 share the same axis of rotation, and the two are firmly fixed together by a rigid connection method (such as welding, key connection, or bolt connection), thereby ensuring that they remain completely synchronized during movement. The arc-shaped protrusion 23 is a curved protrusion at the upper end of the sector block 22, and its shape is designed to contact and cooperate with the guide rod 24, converting the rotational motion of the sector block 22 into the linear or curvilinear motion of the guide rod 24. The protrusion 23 can be a smooth arc surface or a cam with a specific curved profile. The guide rod 24 is a slender rod-shaped component, one end of which cooperates with the arc-shaped protrusion 23, and the other end is fixedly connected to the discharge baffle 12. The guide rod 24 slides in the first groove 25, transmitting the swing of the sector block 22 to the discharge baffle 12 through the arc-shaped protrusion 23, realizing the precise displacement of the discharge baffle 12. The guide rod 24 can have a circular or square cross section to adapt to different guiding requirements. The fixed connection of the material discharge baffle 12 refers to the rigid connection between the guide rod 24 and the material discharge baffle 12, such as by bolts, pins, or welding, to ensure that the movement of the guide rod 24 can be directly and accurately transmitted to the material discharge baffle 12, causing it to move along a preset trajectory. The first chute 25 is a narrow slot provided on the hopper 9 to restrict the movement direction of the guide rod 24, allowing it to slide only along the trajectory of the chute. The shape and size of the first chute 25 match the guide rod 24 to ensure the stability and accuracy of the guide rod 24 during sliding. The first chute 25 can be straight or curved, and can be surface treated as needed to reduce friction. The reset assembly 26 is a mechanism used to automatically return the material discharge baffle 12 (and other components linked with it) to the initial position after the external force is released. Common reset assemblies 26 include springs (such as compression springs, tension springs, or torsion springs), or counterweights or pneumatic / hydraulic reset devices.

[0056] The solution proposed in this application solves the problem of precise control of the synchronous movement of the pipe baffle 11 and the discharge baffle 12 through an ingenious mechanical linkage design. When the sector block 22 on the frame 1 receives the drive signal and begins to swing back and forth, the pipe baffle 11 will rotate synchronously because the sector block 22 is coaxially and fixedly connected to the pipe baffle 11. At the same time, the arc-shaped protrusion 23 at the upper end of the sector block 22 will contact the guide rod 24 and push the guide rod 24. The guide rod 24 slides in the first sliding groove 25 provided on the discharge hopper 9 and transmits this movement to the discharge baffle 12 fixedly connected to it. In this way, the pipe baffle 11 and the discharge baffle 12 can achieve highly synchronous opening or closing actions through the single drive of the sector block 22. When the sealing plug finishes counting, the sector block 22 swings, driving the pipe baffle 11 to rotate and replace the discharge pipe 10, while pushing the discharge baffle 12 to slide and close the front side of the counting slot 7. After the pipe baffle 11 has rotated, the reset component 26 acts on the discharge baffle 12, causing it to automatically return to its initial position. Simultaneously, the sector block 22 and the pipe baffle 11 maintain the changed position, thus preparing for the next counting and replacement. This linkage mechanism ensures the smoothness and accuracy of the material feeding process, effectively avoiding material jamming or leakage caused by asynchronous baffles.

[0057] The connecting pin 27 is a common mechanical connector that provides a stable connection point on the sector block 22, allowing other components to be reliably fixed to it. The connecting pin 27 can be fixed near the geometric center or center of gravity of the sector block 22 using bolts, rivets, welding, etc., to ensure uniform force distribution and balanced movement. The second spring 28 is an elastic element that provides restoring or buffering force for the swing of the sector block 22. This spring can be a tension spring, storing and releasing energy through its elastic deformation, thereby assisting the reciprocating motion of the sector block 22 and helping it maintain stability in a specific position. The first telescopic rod 29 is a telescopic rod-like structure that transmits the elastic force of the second spring 28 to the frame 1 and allows the spring to extend and retract during the swing of the sector block 22. This telescopic rod can consist of multiple sleeves, with an internal guide structure to achieve smooth extension and retraction, ensuring effective force transmission. The sliding connection between the first telescopic rod 29 and the frame 1 allows the telescopic rod to move freely in a specific direction on the frame 1. This connection method can be achieved using linear guides, sliding bearings, or guide sleeves to ensure smooth sliding of the telescopic rod under force, thereby effectively transmitting the force of the second spring 28 and accommodating the swing of the sector block 22. The limit positions of the first telescopic rod 29 refer to its farthest and closest points during extension and retraction. These limit positions are set on the side of the hinge axis of the sector block 22, meaning that the range of motion of the telescopic rod is offset from the swing axis of the sector block 22. The second spring 28 can generate an effective torque to drive the movement of the sector block 22. A limit pin is a pin-shaped structure used to limit the range of motion of mechanical components. Limit pins are set at both ends of the sector block 22 to physically limit the maximum swing angle of the sector block 22, preventing it from exceeding the preset working range. These limit pins can cooperate with the frame 1 or the fixing structure of the sector block 22, contacting it when the sector block 22 swings to a predetermined position, thus providing a clear mechanical stop point.

[0058] The solution of this application ensures more stable and precise synchronous movement of the pipe baffle 11 and the discharge baffle 12 by setting a precise motion control and limiting mechanism on the sector block 22. Specifically, a connecting pin 27 is fixedly connected to the middle of the sector block 22. This connecting pin 27 serves as the point of force application, transmitting the elastic force of the second spring 28 to the sector block 22. The other end of the second spring 28 is fixedly connected to the first telescopic rod 29, which is slidably connected to the frame 1. The extreme positions of the first telescopic rod 29 are all located on the side of the hinge axis of the sector block 22. This offset design ensures that the second spring 28 can always generate a torque during the swing of the sector block 22. This torque can drive the movement of the sector block 22. The elastic coefficient of the second spring 28 is greater than the elastic coefficient of the third spring 2604 in the reset assembly 26. Furthermore, limit pins are fixedly connected to both ends of the sector block 22. These limit pins cooperate with corresponding structures on the frame 1, providing a clear mechanical stop point when the sector block 22 swings to a preset open or closed position. Through the traction of the second spring 28 and the physical limitation of the limit pins, the reciprocating swing range of the sector block 22 is precisely controlled, avoiding overshoot or undershoot, thereby ensuring the accuracy and repeatability of the synchronous opening and closing actions of the pipe baffle 11 and the discharge baffle 12. This synergistic effect ensures a stable and reliable material discharge process for the sealing plug, effectively avoiding material discharge errors caused by unstable swing.

[0059] The system includes a connecting rod 2601, a second slide groove 2602, a support rod 2603, and a third spring 2604. The connecting rod 2601, as a mechanical transmission component, transmits motion or force. It can be a solid or hollow rod with sufficient rigidity, for example, made of metal materials such as steel or aluminum alloy, to ensure stability and reliability during motion transmission. The connecting rod 2601 can be fixedly connected to the discharge baffle 12 by bolts, welding, riveting, etc., to ensure no relative movement between them, thereby achieving precise driving of the discharge baffle 12. The second slide groove 2602 is a structure used for guiding and limiting the moving parts. It can be a straight, arc-shaped, or irregularly shaped groove machined on the wall of the discharge hopper 9, and its inner surface is usually precision-machined to reduce frictional resistance, ensuring smooth sliding of the connecting rod 2601 within it. The design of the second slide groove 2602 should match the shape and movement trajectory of the connecting rod 2601 to accurately guide the movement direction of the connecting rod 2601 and prevent it from deviating or jamming. The support rod 2603 is a structural component that provides support and can also serve as a mounting base or point of application for other components. It can be a rigid rod fixed to the hopper 9, for example, by welding, bolting, or integral molding. The support rod 2603 can be designed in an L-shape, T-shape, or other geometry suitable for installing the spring to ensure it can stably withstand the spring's force and provide a reliable mounting position for the spring. The third spring 2604 is an energy storage element that provides elastic restoring force. It can be a compression spring, tension spring, or torsion spring, the selection of which depends on the direction and magnitude of the required restoring force. For example, when the material discharge baffle 12 moves downwards, if a compression spring is used, the spring is compressed, storing energy; when the driving force is released, the spring releases energy, pushing the material discharge baffle 12 back to its initial position via the support rod 2603 and connecting rod 2601. The stiffness of the spring should be reasonably selected based on the mass of the material discharge baffle 12 and the required restoring speed.

[0060] When the sector block 22 reciprocates on the frame 1 and drives the material discharge baffle 12 downward through the protrusion 23 and guide rod 24 to complete the material discharge operation of the sealing block, the connecting rod 2601, which is fixedly connected to the material discharge baffle 12, also slides in the second groove 2602 on the hopper 9. During this process, the third spring 2604 on the support rod 2603 above the connecting rod 2601 is compressed or stretched due to the movement of the connecting rod 2601, thereby storing elastic potential energy. Once the driving force of the sector block 22 is released, the elastic potential energy stored in the third spring 2604 is released, and the force is transmitted to the connecting rod 2601 through the support rod 2603, thereby driving the material discharge baffle 12 to move upward or backward along the guide action of the first groove 25 and the second groove 2602, so that it quickly and accurately returns to the initial blocking position. The second groove 2602 provides a precise movement trajectory for the connecting rod 2601, avoiding deviation or jamming during the movement. This precise reset mechanism, in conjunction with the sector block 22, the pipe baffle 11, and the discharge baffle 12, forms a highly efficient and stable counting and packaging system, ensuring accurate counting and smooth discharge of the sealing plugs.

[0061] The packaging assembly 13 includes a fixed frame 1301, a lifting platform 1302, a receiving box 1303, an adjusting cover 1304, a bag-supporting suction cup 1305, a compression block 1306, and a sealing block 1307. The fixed frame 1301 serves as the structural support for the entire packaging assembly 13, providing a stable mounting base for other components. The lifting platform 1302 is mounted on the fixed frame 1301 and provides vertical movement to adjust the receiving box 1303 and the packaging bag it carries to a suitable height to accommodate different sized packaging bags or to facilitate subsequent packaging operations. The receiving box 1303 is fixedly connected to the lifting platform 1302 and receives the sealing plug falling from the discharge pipe 10, guiding it into the packaging bag. The adjusting cover 1304 is located below the receiving box 1303 and assists in guiding the sealing plug into the packaging bag, and may provide initial positioning or restriction of the packaging bag opening. The bag-supporting suction cups 1305 are symmetrically distributed below the adjusting cover plate 1304 and can move relative to each other. Their main function is to use suction to open and stabilize the opening of the packaging bag so that the sealing plug can fall in smoothly. The squeezing block 1306 and the sealing block 1307 are both located below the bag-supporting suction cups 1305 and can move relative to each other. The squeezing block 1306 is used to squeeze the packaging bag filled with the sealing plug to expel excess air or make the contents more compact. The sealing block 1307 is used to heat-seal or otherwise seal the opening of the packaging bag to complete the final packaging.

[0062] The fixing frame 1301 provides stable support for the entire packaging assembly 13. The lifting platform 1302, through its vertical movement, can precisely position the receiving box 1303 and the bag to be packaged at the optimal position for receiving the sealing plug. The receiving box 1303 effectively collects and guides the sealing plug into the packaging bag. The adjusting cover 1304 further optimizes the sealing plug introduction process. Once the packaging bag is accurately opened by the bag-opening suction cup 1305, the sealing plug can smoothly fall into the bag. Subsequently, the squeezing block 1306 organizes and vents the sealing plug inside the bag, ensuring a compact package. Finally, the sealing block 1307 reliably seals the packaging bag, completing the entire packaging process. This collaborative working method ensures the continuity, accuracy, and efficiency of the packaging process.

[0063] The following is a specific example: the fixing frame 1301 can be constructed using high-strength aluminum alloy profiles to form a stable frame structure. The lifting platform 1302 can be driven by an electric screw lifting mechanism, with its vertical position precisely controlled by a servo motor. The receiving box 1303 can be made of food-grade stainless steel, with its lower part designed as a conical funnel to ensure smooth introduction of the sealing plug. The adjusting cover 1304 can be composed of two crescent-shaped or fan-shaped plates, connected to a small cylinder via a linkage 16 mechanism to achieve synchronous opening and closing, accommodating packaging bags of different widths. The bag-supporting suction cup 1305 can be made of wear-resistant silicone material, providing negative pressure through a vacuum generator and driven by two sets of relatively moving cylinders to precisely open the packaging bag opening. The extrusion block 1306 can be a pair of pressure plates with elastic cushioning pads, driven by a pneumatic push rod to flexibly extrude the packaging bag. The sealing block 1307 can have a built-in heating rod and temperature sensor. The heating temperature is precisely controlled by a PID controller and the heat sealing of the packaging bag is achieved by a cylinder.

[0064] A column 1308 is fixedly connected to the fixed frame 1301. The lifting platform 1302 is slidably connected to the column 1308. A second telescopic rod 1309 is connected between the lifting platform 1302 and the column 1308. There are two sets of adjusting cover plates 1304. The two sets of adjusting cover plates 1304 are hinged to both sides below the receiving box 1303. A sliding rod 1310 is hinged to the other end of the adjusting cover plate 1304. A third sliding groove 1311 is provided on the fixed frame for the sliding rod 1310 to slide. The column 1308 is a vertical support structure, typically used to provide stability and guidance. It can be a solid or hollow rod-like structure, such as a metal square tube, round tube, or profile, and is securely fixed to the mounting frame 1301 via welding, bolting, or other methods, providing vertical support and a guide rail for the lifting platform 1302. Alternatively, the column 1308 can be a profile with guide rail grooves, or composed of multiple parallel rods to increase stability. A sliding connection allows relative movement between two components, typically in one or more directions. This can be achieved by installing a slider on the side of the lifting platform 1302, which engages with the guide rail on the column 1308, or by installing a guide rod 24 on the column 1308, with the lifting platform 1302 mounted on the guide rod 24 via bearings or bushings, ensuring smooth up-and-down movement of the lifting platform 1302 under the guidance of the column 1308. Furthermore, sliding connections can also be achieved using linear guide pairs, dovetail joints, or other methods to provide higher precision and load-bearing capacity. The second telescopic rod 1309 is a mechanical device capable of changing its length, commonly used to achieve linear motion or provide support. It can be a cylinder, hydraulic cylinder, electric actuator, or screw drive mechanism. For example, a cylinder drives a piston rod to extend or retract via pneumatic pressure, thereby moving the lifting platform 1302 up and down along the column 1308. An electric actuator drives a screw nut via a motor to achieve extension and retraction. Alternatively, a chain or belt drive system can be used, where a motor drives a sprocket or pulley to raise or lower the lifting platform 1302. The adjusting cover 1304 is a plate-like structure used to control material descent or container opening. The hinged connection allows the cover to rotate about an axis. Two sets of adjusting covers 1304 can be symmetrical semi-circular, rectangular, or fan-shaped plates, connected to the two sides of the bottom edge of the receiving box 1303 via hinges such as pins or hinges. When the cover rotates, the bottom outlet of the receiving box 1303 can be opened or closed. In addition, the hinge points can also be located on both sides of the bottom centerline of the receiving box 1303, or synchronous opening and closing can be achieved through the linkage 16 mechanism. The slide rod 1310 is a slender rod-shaped component, usually used to transmit motion or as a guide. One end of it is connected to the free end of the adjusting cover plate 1304 through a hinge such as a pin or universal joint. When the adjusting cover plate 1304 rotates, the slide rod 1310 will swing accordingly. Alternatively, it can be the linkage 16, push rod, etc., as long as it can transmit the motion of the adjusting cover plate 1304. The third slide groove 1311 is a groove-shaped structure on the fixed frame used to guide the movement of the slide rod 1310. It can be a straight, arc-shaped, or irregularly shaped groove, and its shape matches the movement trajectory of the slide rod 1310. The slide rod 1310 slides in the third slide groove 1311, thereby converting the rotational motion of the adjusting cover plate 1304 into controlled linear or curvilinear motion. Alternatively, it could be a guide hole, guide sleeve, or anything else that can restrict the movement direction of the slide rod 1310 and guide its sliding.

[0065] The solution of this application ensures the stability and precise movement of the receiving box 1303 in the vertical direction by fixing the column 1308 to the fixed frame 1301 and slidingly connecting the lifting platform 1302 to the column 1308. The connection of the second telescopic rod 1309 provides reliable lifting power for the lifting platform 1302, enabling it to adjust its height according to packaging requirements. Simultaneously, two sets of adjusting covers 1304 are hinged to both sides below the receiving box 1303 and linked to the third sliding groove 1311 on the fixed frame via the sliding rod 1310. This linkage mechanism allows the opening and closing of the adjusting covers 1304 to be synchronized or coordinated with the lifting movement of the lifting platform 1302. For example, when the lifting platform 1302 descends to a certain position, the adjusting covers 1304 automatically open to allow materials to fall into the packaging bag; when the lifting platform 1302 rises, the adjusting covers 1304 automatically close to prevent materials from scattering. This ingenious mechanical design enables the packaging component 13 to achieve precise material delivery and efficient packaging operations, effectively solving the problems of scattering, blockage, and operational incoordination that may occur during material transfer and packaging in traditional packaging components 13, and significantly improving the automation level and packaging efficiency of the equipment.

[0066] The following is a specific example: Two parallel H-shaped steel members can be fixedly connected to the fixed frame 1301 as columns 1308. A slider with rollers can be installed on the side of the lifting platform 1302. These rollers roll in the inner grooves of the H-shaped steel members, achieving a smooth sliding connection of the lifting platform 1302. The second telescopic rod 1309 can be an electric push rod, with one end hinged to the bottom of the lifting platform 1302 and the other end hinged to the lower part of the column 1308. The lifting platform 1302 is moved up and down by controlling the extension and retraction of the electric push rod. Two sets of adjusting covers 1304 can be made of stainless steel plates and are hinged to the outer edge of the bottom of the receiving box 1303 by pins. The slide rod 1310 can be a stainless steel round bar, with one end connected to the free end of the adjusting cover 1304 by a universal joint. The fixed frame can be machined with an arc-shaped third slide groove 1311. The other end of the slide rod 1310 is equipped with a ball bearing. The ball bearing rolls in the third slide groove 1311. Thus, when the lifting platform 1302 descends, the movement of the slide rod 1310 drives the adjusting cover plate 1304 to rotate outward and open. When the lifting platform 1302 rises, the adjusting cover plate 1304 rotates inward and closes.

[0067] The packaging assembly 13 also includes a base 1312, on which a bag-feeding gripper 1313 is slidably connected. An inclined slide plate 1314 is fixedly connected to the base 1312, located below the compression block 1306. The inclined slide plate 1314 has a through groove 1315 for the bag-feeding gripper 1313 to engage with. The base 1312 serves as a support structure for the packaging assembly 13, providing a stable mounting foundation for other components. It can be made of metal sheet or high-strength engineering plastic sheet and is securely connected to the fixing frame 1301 by bolts or welding to ensure the stability and operational accuracy of the entire packaging assembly 13. The bag-feeding gripper 1313 is used to grasp, convey, and position the packaging bag. It can be a pneumatic or electric gripper, using clamping or suction to remove the packaging bag from a preset position and deliver it to the packaging station. Its design should ensure stable gripping of the packaging bag without damage. The inclined slide plate 1314 provides an inclined surface for guiding the movement of the packaging bag or related components. It can be made of a smooth metal plate or a composite material plate with a low-friction coating. Its inclination angle can be adjusted according to the size of the packaging bag and conveying requirements to achieve smooth movement using gravity or auxiliary thrust. The through slot 1315 is a channel formed on the inclined slide plate 1314, allowing the bag-feeding gripper 1313 or other components to pass through or engage. The shape and size of the slot should match the structure of the bag-feeding gripper 1313 to ensure smooth passage of the bag during conveying and accurate positioning of the bag below the compression block 1306.

[0068] The solution of this application achieves automatic conveying and precise positioning of packaging bags by introducing a base 1312, a bag-feeding gripper 1313, an inclined slide plate 1314, and a through groove 1315 in the packaging assembly 13. Specifically, the base 1312 provides a stable mounting platform for the entire bag-feeding mechanism. The bag-feeding gripper 1313 is slidably connected to the base 1312 and is responsible for gripping individual packaging bags from the packaging bag hopper. The inclined slide plate 1314 is fixedly connected to the base 1312 and is located below the compression block 1306. Its inclined design helps the packaging bag slide smoothly down or be guided. The through groove 1315 provided on the inclined slide plate 1314 precisely matches the movement path of the bag-feeding gripper 1313, allowing the bag-feeding gripper 1313 to follow the guidance of the inclined slide plate 1314 and pass through the through groove 1315 after gripping the packaging bag, accurately delivering the packaging bag to the predetermined packaging position of the bag-supporting suction cup 1305. This structural combination enables packaging bags to be automatically, continuously and accurately fed into the packaging station, thus forming a complete automated packaging process with components such as the bag-supporting suction cup 1305, the squeezing block 1306 and the sealing block 1307 in the packaging assembly 13. This effectively solves the problem of inaccurate manual placement or positioning of packaging bags, and significantly improves the automation level and packaging efficiency of the equipment.

[0069] The following is a specific example. The base 1312 can be a rectangular frame welded from 5mm thick stainless steel sheet, fixed to the fixing frame 1301 with M8 bolts, providing sturdy and corrosion-resistant support. The bag-feeding gripper 1313 can be a pneumatically driven parallel gripper, with wear-resistant polyurethane anti-slip pads at its gripping ends. It grips and releases the packaging bag through the extension and retraction of a small cylinder, and is mounted on two precision linear guide rails, driven by a stepper motor to reciprocate on the base 1312. The inclined slide plate 1314 can be an anodized aluminum alloy plate with a preset inclination angle of 15 degrees to utilize gravity to assist the downward sliding of the packaging bag, and is directly fixed to the base 1312 with countersunk screws. The through slot 1315 can be a rectangular opening that matches the gripping width of the bag feeding claw 1313. Its length is designed to allow the claw to pass through completely during the bag feeding process, ensuring that the packaging bag can be accurately placed in the middle of the two sets of bag support suction cups 1305, waiting to be filled.
