Description

Technical Field

[0001] This invention relates to the field of needle feeding technology, and in particular to a lifting-type sequential feeding machine. Background Technology

[0002] In practical applications of needle-feeding machines, the feeding process has long relied on manual operation. Operators must manually move the trays one by one to designated locations according to the needle-feeding rhythm, and then temporarily store the trays after needle feeding. This manual intervention not only significantly reduces production efficiency but also greatly increases the labor intensity of operators, especially in high-frequency operation environments where repetitive actions easily lead to fatigue and operational errors. Furthermore, during the stacking process, the bottom area of ​​the trays is difficult to clean thoroughly due to structural limitations, and dust, debris, and other impurities easily accumulate. When a new tray is placed on top of already stacked trays, these contaminants can easily fall into the new tray, causing cross-contamination, affecting the cleanliness and quality stability of subsequent products, and adding an extra cleaning burden to the trays' release and reuse. Current technologies lack effective automation solutions, failing to simultaneously achieve efficient feeding and contamination control, thus increasing the risk of production interruptions.

[0003] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0022] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Reference Figures 1 to 7 As shown, the present invention provides an outdoor high-voltage switchgear with intelligent dehumidification function, comprising: The frame 1 is divided into a palletizing area and a feeding area. Multiple pallet plates 11 are detachably connected to the inner side of the palletizing area along the vertical direction. Vertical guide rails 13 and vertical toothed plates 15 are fixedly connected to the inner side of the feeding area. The feeding mechanism 2 is movably connected in the feeding area. It includes a horizontal picking unit and a vertical sliding unit to complete the lifting and sequential feeding. The horizontal picking unit includes a carrying plate 21. The vertical sliding unit is located on the bottom side of the carrying plate 21. The top of the carrying plate 21 is fixedly connected to a blower box 212. The loading pallet 3 is placed on the pallet 11 in the stacking area; The linkage guide mechanism 4 is connected between the feeding mechanism 2 and the air blowing box 212 to change the air direction.

[0024] This feeding machine replaces traditional manual operation with an automated mechanism, improving feeding efficiency and reducing labor intensity. It also assists in cleaning through a linkage guide mechanism 4, effectively preventing dust from contaminating the material tray and improving the overall convenience and cleanliness of the operation.

[0025] For ease of understanding, the following explains some key terms in this embodiment: The frame 1 is the supporting structure of the entire feeding machine. Its internal space is divided into a palletizing area and a feeding area, which are used for stacking material trays and actual feeding operations, respectively.

[0026] The palletizing area is a region used to temporarily store pallets that are to be loaded or have already been loaded. Multiple pallets 11 are provided on its inner side. These pallets 11 are detachably connected in the vertical direction, which makes it easy to adjust the stacking height according to the number of pallets.

[0027] The feeding area is the area where the feeding mechanism 2 performs actual material picking and feeding operations. Vertical guide rails 13 and vertical toothed plates 15 are fixedly connected to its inner side, providing guidance and power transmission for the vertical movement of the feeding mechanism 2.

[0028] The feeding mechanism 2 is the core component for realizing sequential feeding of material trays by lifting and lowering. It is movably connected in the feeding area and completes the gripping, lifting and placement of material trays through the coordinated action of the horizontal picking unit and the vertical sliding unit.

[0029] The horizontal material handling unit is part of the feeding mechanism 2. It is mainly responsible for grabbing the material tray in the horizontal direction. Its core component is the carrier plate 21, which is used to support the material tray.

[0030] The vertical sliding unit is another part of the feeding mechanism 2, which is responsible for realizing the vertical lifting and lowering movement of the loading plate 21 and the material tray it carries.

[0031] The air blower box 212 is fixedly connected to the top of the carrier plate 21 and is used to generate airflow during the feeding process to assist in the separation or cleaning of the material tray.

[0032] The loading pallet 3 is the container that actually carries the materials. It is placed on the pallet 11 in the stacking area and waits to be taken away by the loading mechanism 2.

[0033] The linkage guide mechanism 4 is connected between the feeding mechanism 2 and the air blowing box 212. Its function is to change the airflow direction generated by the air blowing box 212 according to the movement state or needs of the feeding mechanism 2, so as to achieve more precise auxiliary functions.

[0034] Specifically, the feeding machine of this application achieves this through the following methods: The frame 1 can be welded from metal profiles to form a stable frame structure, and its internal space is divided into a palletizing area and a loading area. Multiple pallet plates 11, detachably connected vertically along the inner side of the palletizing area, can be fixed with bolts using L-shaped brackets to facilitate adjustment according to the stacking height of the pallets. A vertical guide rail 13, fixedly connected to the inner side of the loading area, can be a T-shaped guide rail or a cylindrical guide rail, providing linear guidance for the vertical movement of the loading mechanism 2. A vertical gear plate 15, which can be a rack, is fixed to the side of the vertical guide rail 13 by welding or bolting, and engages with the gears of the loading mechanism 2 to achieve lifting and lowering.

[0035] The feeding mechanism 2, as an integral moving platform, moves vertically by cooperating with the vertical guide rail 13 of the frame 1 via rollers or sliders. The feeding mechanism 2 includes a horizontal picking unit and a vertical sliding unit. The horizontal picking unit can be composed of a carrying plate 21, on which manual or pneumatic clamps are installed for gripping the feeding tray 3. The vertical sliding unit can be driven by a simple screw lifting mechanism to raise and lower the carrying plate 21. The carrying plate 21 can be a flat metal plate used to support the feeding tray 3. The air blowing box 212 can be a simple fan outlet, fixed to the top of the carrying plate 21, used to generate upward airflow to assist cleaning. An air supply pipe is installed inside the air blowing box 212; however, this is not shown in the figure as it is not described in detail in the prior art.

[0036] The loading pallet 3 can be a standard rectangular container with its bottom designed to be stably placed on the pallet 11 in the palletizing area, waiting to be picked up by the loading mechanism 2.

[0037] The linkage guiding mechanism 4 can be a simple mechanical linkage mechanism, which is connected between the feeding mechanism 2 and the air blowing box 212. When the feeding mechanism 2 moves to a specific position, the linkage mechanism drives the baffle inside the air blowing box 212 to rotate through mechanical linkage, thereby changing the direction of the airflow generated by the air blowing box 212 to achieve precise blowing of the material tray.

[0038] The lifting-type sequential feeding machine proposed in this application achieves automated and continuous feeding of material trays through the coordinated action of the frame 1, feeding mechanism 2, feeding tray 3, and linkage guiding mechanism 4. This solution effectively avoids the problems of low efficiency and high labor intensity in traditional manual feeding. Simultaneously, by controlling the airflow direction through the air blowing box 212 and the linkage guiding mechanism 4, auxiliary cleaning of the bottom of the material tray can be performed during the feeding process, reducing dust contamination. This solves the problem of inconvenient bottom cleaning during tray stacking and dust falling into the next tray, improving the cleanliness of the material trays and the convenience of subsequent outbound processing.

[0039] In some of the embodiments described above in this application, the horizontal material handling unit of the feeding mechanism 2 only describes the carrier plate 21 and the blower box 212. However, in its implementation, how to achieve stable and precise horizontal gripping and movement of the feeding tray 3 to ensure the smoothness and reliability of the feeding process still presents technical challenges.

[0040] In response, this application further proposes an improved horizontal material handling unit, which also includes a horizontal guide rail 22, which is fixedly connected to the top of the carrying plate 21. A slide block 23 is slidably connected to the top of the horizontal guide rail 22. A transmission motor 291 is fixedly connected to the bottom of the carrying plate 21. The output shaft of the transmission motor 291 is drivenly connected to a toothed pulley set 29. A connecting tooth 231 that meshes with the toothed pulley set 29 is fixedly connected to the side of the slide block 23 near the toothed pulley set 29. A hydraulic cylinder 24 is detachably connected to the slide block 23. A movable clamp 25 is movably connected to the output end of the hydraulic cylinder 24. A horizontal traction chain 28 for limiting the position is connected between the slide block 23 and the carrying plate 21.

[0041] Specifically, the horizontal guide rail 22 is a mechanical component used to guide the slide 23 in linear motion. It is typically made of high-strength materials with precision-machined surfaces to ensure low friction and high precision. The horizontal guide rail 22 can take various forms, such as linear rolling guides, sliding guides, or dovetail guides, the choice depending on the required load-bearing capacity, motion accuracy, and environmental conditions. By fixing the horizontal guide rail 22 to the top of the carrier plate 21, a stable motion foundation is provided for subsequent horizontal material handling operations. The slide 23 is a component that slides along the horizontal guide rail 22, used to support and drive the material handling mechanism. The slide 23 typically has internal rolling elements or sliding bushings to reduce friction with the horizontal guide rail 22. Its design should have sufficient rigidity and strength to withstand the loads and impacts generated during material handling. The motion accuracy of the slide 23 directly affects the positioning accuracy of the material handling. The transmission motor 291 is the actuator that provides the power source for the horizontal material handling unit. It is typically a servo motor or stepper motor, capable of achieving precise speed and position control. The conveyor motor 291 converts rotary motion into linear motion via its output shaft, driving the slide 23 to move along the horizontal guide rail 22. Its power and torque should be matched to the load and motion requirements of the material handling unit. The toothed pulley assembly 29 is a transmission mechanism consisting of a driving toothed pulley, a driven toothed pulley, and a toothed belt. It enables synchronous transmission and has advantages such as smooth transmission, low noise, and no lubrication required. Here, the toothed pulley assembly 29 efficiently transmits the rotary motion of the conveyor motor 291 to the connecting tooth 231, thereby driving the slide 23 to move horizontally. The connecting tooth 231 is a component fixed to the slide 23 and meshing with the toothed pulley assembly 29. Its tooth profile matches the tooth profile of the toothed pulley assembly 29, ensuring precise synchronization and no slippage during transmission. The connecting tooth 231 transmits the linear motion force of the toothed pulley assembly 29 to the slide 23, causing it to move along the horizontal guide rail 22. The hydraulic cylinder 24 is an actuator that converts hydraulic energy into linear reciprocating motion. It uses hydraulic oil pressure to drive the piston rod to extend and retract, thereby providing a powerful clamping or pushing force. The hydraulic cylinder 24 features high output force, high rigidity, and fast response, making it suitable for applications requiring large clamping forces. Here, the hydraulic cylinder 24 drives the movable clamp 25 to perform clamping actions. The hydraulic cylinder 24 can be selected as a single-acting or double-acting type as needed and can be equipped with a corresponding hydraulic control valve for precise control. The movable clamp 25 is the end effector connected to the output end of the hydraulic cylinder 24, used to directly contact and clamp the loading tray 3 or the items on it. The design of the movable clamp 25 should take into account the shape, size, and material of the clamped items to ensure reliable clamping without damage. The movable clamp 25 can adopt various structures, such as two-finger clamps, three-finger clamps, or specially customized clamps, with its clamping force provided by the hydraulic cylinder 24. The horizontal traction chain 28 is a limiting and auxiliary transmission device connecting the slide 23 and the carrying plate 21. It typically consists of a series of links and possesses a certain degree of flexibility and strength.The main function of the horizontal traction chain 28 is to limit the range of motion of the slide 23, prevent it from detaching from the horizontal guide rail 22, and in some designs, it can assist or synchronize the movement of the slide 23 to improve the stability and reliability of the system.

[0042] Through the above technical solution, the horizontal material handling unit is equipped with a horizontal guide rail 22 and a slide 23 on the top of the carrying plate 21. A transmission mechanism consisting of a transmission motor 291, a toothed pulley set 29, and connecting teeth 231 drives the slide 23 to move precisely horizontally. A hydraulic cylinder 24 drives a movable clamp 25 to reliably clamp the loading pallet 3, while a horizontal traction chain 28 further ensures the stability and limiting of the slide 23's movement. This design enables the loading mechanism 2 to achieve stable and precise horizontal gripping and movement of the loading pallet 3, effectively solving the problem of the lack of a specific implementation mechanism for horizontal material handling in the basic solution. The combination of mechanical transmission and hydraulic clamping significantly improves the positioning accuracy and repeatability of material handling, enhances adaptability to different loading pallets 3, thereby improving the automation level and operating efficiency of the entire loading process and reducing the risk of material damage.

[0043] In some embodiments described above in this application, a lifting-type sequential feeding machine is proposed. The horizontal material-grabbing unit in its feeding mechanism 2 slides on a horizontal guide rail 22 via a slide block 23 to complete the material-grabbing operation. The slide block 23 is driven horizontally by a transmission motor 291 to drive a toothed pulley group 29 and connecting teeth 231, and uses a hydraulic cylinder 24 and a movable clamp 25 to hold the material. However, in actual operation, especially when the slide block 23 is carrying material or performing clamping and traction, the slide block 23 may not slide stably on the horizontal guide rail 22, and may easily wobble or experience excessive friction, thus affecting the accuracy and efficiency of material grabbing, and may even lead to material falling or accelerated equipment wear.

[0044] In this regard, this application further proposes that, in order to enhance the stability of the slide 23 during horizontal movement and reduce running resistance, side plates 26 fixedly connected to the load plate 21 are symmetrically arranged on both sides of the slide 23, and multiple guide wheels 27 are rotatably connected to one side of the load plate 21.

[0045] Specifically, the side plates 26 are plate-like structures fixedly connected to both sides of the carrying plate 21. Their main function is to provide additional lateral support and guidance for the slide 23, effectively limiting the horizontal sway and shaking of the slide 23, thereby enhancing the operational stability of the slide 23. The side plates 26 can be made of high-strength, wear-resistant materials, such as steel plates, aluminum alloy plates, or engineering plastics, and are firmly fixed to the carrying plate 21 by bolts, riveting, or welding. Their design height and length should ensure continuous and sufficient lateral support throughout the entire stroke of the slide 23. By symmetrically setting, the slide 23 can be kept balanced under force, avoiding tilting or jamming caused by uneven force on one side.

[0046] Meanwhile, multiple guide wheels 27 rotatably connected to one side of the carrying plate 21 are mainly used to cooperate with the side of the slide 23 or the side plate 26, converting the sliding friction that may occur during the horizontal movement of the slide 23 into rolling friction. The guide wheels 27 are usually made of wear-resistant materials (such as polyurethane, nylon, or hardened steel), and have integrated precision bearings inside. They are reliably installed on the side of the carrying plate 21 by means of pins or bolts. The arrangement of multiple guide wheels 27 can distribute the load, provide more uniform rolling support, further reduce motion resistance, and ensure that the sliding process of the slide 23 on the horizontal guide rail 22 is more stable and smooth.

[0047] Through the above technical solution, side plates 26 are symmetrically arranged on both sides of the slide 23, providing robust lateral guidance and support for the slide 23, effectively suppressing its swaying and shaking during horizontal movement, and significantly improving the operating accuracy and stability of the horizontal material handling unit. Furthermore, by rotatably connecting multiple guide wheels 27 on one side of the carrying plate 21, the sliding friction between the slide 23 and the carrying plate 21 is converted into rolling friction, greatly reducing motion resistance and making the movement of the slide 23 easier and smoother, reducing the load on the conveyor motor 291 and reducing wear on mechanical parts. This structural design not only ensures the accuracy and reliability of material handling, avoiding material damage or falling due to unstable sliding, but also extends the service life of the equipment, thereby comprehensively improving the operating efficiency and overall performance of the feeding machine.

[0048] When a lifting-type sequential feeding machine is used for feeding, the precise gripping and stable traction of the feeding pallet by the feeding mechanism is crucial to ensuring the efficiency and smoothness of the entire feeding process. If the feeding pallet is not accurately positioned on the carrying plate or is not securely connected to the movable clamp, it may lead to feeding failure, material spillage, or unstable equipment operation, thereby affecting the accuracy and reliability of feeding.

[0049] In this regard, this application further proposes that a limit baffle 211 is fixedly connected to the top of the loading plate 21, and a protruding rod matching the movable clamp 25 is fixedly connected to the bottom of the loading tray 3 for clamping and traction.

[0050] Specifically, the limiting baffle 211 is a structure fixedly connected to the top of the carrier plate 21, and its main function is to provide precise positioning for the loading tray 3. When the loading tray 3 is placed on the carrier plate 21, the limiting baffle 211 can limit the horizontal movement range of the loading tray 3, ensuring that it is always in the preset accurate position, thereby providing a stable foundation for subsequent clamping operations. This baffle can be designed as an L-shaped, U-shaped, or polygonal structure to adapt to loading trays 3 of different shapes and sizes, and can be made of wear-resistant materials such as metal and high-strength plastics. At the same time, the protruding rod is a protruding structure fixedly connected to the bottom of the loading tray 3. Its design purpose is to serve as a dedicated clamping point for the movable clamp 25. By setting the protruding rod at the bottom of the loading tray 3, a standardized, easily identifiable, and gripping interface can be provided for the movable clamp 25, avoiding potential damage or instability caused by the movable clamp 25 directly clamping the loading tray 3 body. The shape and size of the protruding rod are precisely designed according to the clamping mechanism of the movable clamp 25 to ensure a tight and reliable fit between the two. The compatibility between the protruding rod and the movable clamp 25 is crucial for achieving stable clamping and traction. This means that the geometry, dimensions, and material properties of the protruding rod are carefully designed to ensure that the movable clamp 25 can firmly and undamage it. When the movable clamp 25 is closed, its clamping surface can fit tightly against the surface of the protruding rod, generating sufficient friction or mechanical locking, thereby stably tractioning the loading pallet 3 when the loading mechanism 2 moves up, down, or horizontally, preventing it from shaking, falling off, or shifting during movement.

[0051] Through the above technical solution, a limiting baffle 211 is set at the top of the loading plate 21, which can effectively and accurately position the loading pallet 3 horizontally, ensuring that the loading pallet 3 is in the correct initial position before being clamped by the movable clamp 25. At the same time, the protruding rod fixedly connected to the bottom of the loading pallet 3 is designed to perfectly match the movable clamp 25, enabling the movable clamp 25 to firmly and reliably clamp and pull the loading pallet 3. This synergistic design greatly improves the gripping accuracy and pulling stability of the loading mechanism 2 on the loading pallet 3, effectively avoiding possible positioning deviations and the risk of falling off during the loading process, thereby significantly improving the operating efficiency and reliability of the entire loading machine.

[0052] In some embodiments of this application, the feeding mechanism 2 achieves sequential feeding via a vertical sliding unit. However, in actual operation, if the vertical sliding unit lacks a precise and stable driving and guiding mechanism, the feeding mechanism 2 may face problems such as inaccurate positioning, unstable operation, or insufficient load-bearing capacity when performing vertical lifting, thereby affecting the efficiency and reliability of feeding.

[0053] This application further proposes a specific implementation of the vertical sliding unit, which includes a lifting motor 214 and a vertical slider 215. The lifting motor 214, as the power source of the vertical sliding unit, is responsible for providing the driving force required for lifting. It can be a stepper motor, servo motor, or DC motor, etc. By precisely controlling the motor's speed and direction of rotation, the precise lifting and positioning of the carrier plate 21 is achieved. The lifting motor 214 is fixedly connected to the bottom end of the carrier plate 21. This installation method allows the lifting motor 214 to rise and fall together with the carrier plate 21, resulting in a compact structure and convenient power transmission. The output shaft of the lifting motor 214 is fixedly connected to a gear that matches the vertical gear plate 15 on the frame 1. This gear and the vertical gear plate 15 form a gear and rack transmission mechanism. When the lifting motor 214 rotates, the gear on its output shaft meshes with the vertical gear plate 15, converting the rotational motion into the linear lifting motion of the carrier plate 21. This transmission method has advantages such as stable transmission ratio, strong load-bearing capacity, and high positioning accuracy.

[0054] Meanwhile, the vertical slider 215, serving as a guide and support component of the vertical sliding unit, is slidably connected to the vertical guide rail 13 on the frame 1. The vertical guide rail 13 provides a precise linear motion trajectory for the vertical slider 215. The guide rail can be in the form of a linear guide rail, dovetail guide rail, or cylindrical guide rail, etc., and works in conjunction with the slider to effectively restrict the degree of freedom of the carrier plate 21 in the horizontal direction, ensuring that it moves only in the vertical direction, thereby guaranteeing the stability and accuracy of the lifting process. The vertical slider 215 is usually made of wear-resistant material, and rolling bearings or sliding bearings can be integrated internally to reduce frictional resistance and improve motion accuracy and service life.

[0055] Furthermore, to further enhance the stability and safety of the lifting process, a vertically installed traction chain 14 is provided between the bottom of the loading platform 21 and the bottom of the frame 1. The vertical traction chain 14 serves as an auxiliary or limiting mechanism, its function potentially including providing additional stability during lifting to prevent the loading platform 21 from tilting or swaying in extreme situations; or acting as a safety protection mechanism to provide support or limit in the event of a failure of the main lifting mechanism, ensuring the safety of the equipment and operators. The traction chain is typically made of high-strength metal materials, possessing excellent tensile and wear resistance.

[0056] Through the above technical solution, this application provides a stable, precise, and reliable lifting drive and guiding mechanism for the vertical sliding unit of the feeding mechanism 2. The lifting motor 214 efficiently transmits power to the carrier plate 21 through gears meshing with the vertical toothed plate 15, achieving precise vertical positioning and controllable lifting speed. Simultaneously, the sliding cooperation between the vertical slider 215 and the vertical guide rail 13 effectively suppresses lateral swaying of the carrier plate 21 during lifting, ensuring smooth movement. Furthermore, the vertically arranged vertical traction chain 14 further enhances the stability and safety of the carrier plate 21 during lifting, effectively preventing the risk of accidental tilting or falling. This enables the feeding mechanism 2 to complete sequential lifting operations with higher precision and reliability, significantly improving the efficiency and safety of the overall feeding process.

[0057] In some embodiments described above, the air blowing box 212 of the feeding mechanism 2 needs to change its airflow direction to adapt to different feeding requirements. However, achieving precise and synchronized control of the airflow direction within the air blowing box 212, especially when efficient integration of airflow regulation with the existing power system of the feeding mechanism 2, may present challenges. Simply setting up a single airflow guiding mechanism may not be sufficient to ensure coordinated operation of multiple airflow guiding components, thereby affecting the stability and efficiency of feeding.

[0058] To address this, this application further proposes a linkage guiding mechanism 4, which includes multiple first rotating rods 41. These first rotating rods 41 are key components for driving the guide plates 213 to adjust their angles. They are typically slender rod-shaped structures, with both ends designed to rotatably connect to the inner wall of the carrier plate 21, ensuring smooth rotation around its own axis. The first rotating rods 41 can be made of metal materials with good rigidity and wear resistance, such as stainless steel or aluminum alloy, to ensure stability and service life during transmission. Multiple parallel guide plates 213 are rotatably connected inside the air-blowing box 212. The guide plates 213 are components that directly contact the airflow and change its direction. They are typically flat or have a certain curvature and are arranged in parallel inside the air-blowing box 212. The guide plates 213 can be made of lightweight, high-strength materials, such as engineering plastics or thin metal plates, to reduce inertia and improve response speed. By adjusting the angle of the guide plates 213, precise control of the airflow direction and distribution of the air-blowing box 212 can be achieved. A second rotating rod 42 is rotatably connected between the outer wall of the guide plate 213 and the blower box 212. The second rotating rod 42 is a transmission component connecting the guide plate 213 and the first rotating rod 41. One end of the second rotating rod 42 is rotatably connected to the outer wall of the guide plate 213, and the other end is connected to the sprocket assembly 43. The design of the second rotating rod 42 ensures that the rotation of the guide plate 213 can be effectively transmitted to the sprocket assembly 43, thereby driving the entire linkage mechanism. The sprocket assembly 43 is drively connected between the second rotating rod 42 and the first rotating rod 41. The sprocket assembly 43 is used to transmit power and motion between the second rotating rod 42 and the first rotating rod 41. It typically consists of a chain and at least two sprockets, one sprocket mounted on the second rotating rod 42 and the other sprocket mounted on the first rotating rod 41. The use of the sprocket assembly 43 enables precise synchronous transmission, ensuring that the angle adjustment of the guide plate 213 is consistent with the rotation of the first rotating rod 41. A shaft 44 is rotatably connected to the inner bottom wall of the carrying plate 21. Shaft 44 is the main drive shaft of the linkage guiding mechanism 4, and is rotatably connected to the inner bottom wall of the carrying plate 21. Shaft 44 receives power from the transmission motor 291 and distributes the power to each of the first rotating rods 41 via a bevel gear set 45. Shaft 44 is typically made of high-strength steel to withstand transmission torque. A horizontal pulley 46 is coaxially fixed to the top of shaft 44 and is drive-connected to the output shaft of the transmission motor 291. The horizontal pulley 46 is mounted on the top of shaft 44 and is connected to the output shaft of the transmission motor 291 via a belt drive. It serves as the power input, transmitting the rotational motion of the transmission motor 291 to shaft 44. The horizontal pulley 46 can be made of wear-resistant rubber or polyurethane belts combined with metal or plastic wheels to achieve smooth, low-noise power transmission. A bevel gear set 45 is provided between the shaft 44 and the first rotating rod 41. The bevel gear set 45 is used to transmit power between the shaft 44 and the first rotating rod 41, since the two are usually perpendicular to each other.The bevel gear set 45 consists of a driving gear and a driven gear. The driving gear is coaxially and fixedly connected to the shaft 44, and the driven gear is coaxially and fixedly connected to the first rotating rod 41. This gear set can effectively change the transmission direction and convert the horizontal rotation of the shaft 44 into the vertical rotation of the first rotating rod 41. A vertical pulley set 47 is connected between adjacent first rotating rods 41 to ensure their synchronous rotation. It typically consists of two pulleys mounted on adjacent first rotating rods 41 and a belt.

[0059] Through the above technical solution, the linkage guide mechanism 4 is designed as a complex transmission chain including multiple first rotating rods 41, guide plates 213, second rotating rods 42, sprocket sets 43, shafts 44, horizontal pulleys 46, bevel gear sets 45, and vertical pulley sets 47, achieving precise and synchronous adjustment of the guide plates 213 inside the air-blowing box 212. The output shaft of the transmission motor 291 drives the shaft 44 through the horizontal pulley 46, and then transmits power to the first rotating rods 41 through the bevel gear set 45. Adjacent first rotating rods 41 rotate synchronously through the vertical pulley set 47, ensuring that all guide plates 213 are adjusted in a coordinated manner. The guide plates 213 are linked with the first rotating rods 41 through the second rotating rods 42 and sprocket sets 43, thereby enabling precise changes in the air outlet direction and airflow distribution of the air-blowing box 212 according to the feeding requirements. This design not only improves the precision of airflow control, ensuring the stability and accuracy of material feeding, but also makes full use of the power of the existing conveyor motor 291, avoiding the need for additional drive devices, simplifying the structure, reducing energy consumption, and improving the automation level and operating efficiency of the entire feeder.

[0060] In some embodiments described above in this application, the linkage guide mechanism 4 transmits power between the shaft 44 and the first rotating rod 41 via a bevel gear set 45, thereby changing the airflow direction of the guide plate 213 inside the blower box 212. However, in practical applications, to ensure that the guide plate 213 can adjust its angle accurately and stably to adapt to different feeding requirements and material characteristics, it may be necessary to optimize the transmission ratio to provide more suitable torque or speed, thereby achieving finer airflow control.

[0061] In response, this application further proposes a specific structure for the bevel gear set 45. This bevel gear set 45 consists of a driving gear and a driven gear. The driving gear receives power input and is coaxially and fixedly connected to the shaft 44; the rotation of the shaft 44 directly drives the driving gear. The driven gear outputs power and is coaxially and fixedly connected to the first rotating rod 41; the rotation of the driven gear drives the first rotating rod 41 to rotate, which in turn drives the guide plate 213 to rotate via the sprocket set 43 and the second rotating rod 42. To optimize the transmission ratio, this application specifically designs the diameter of the driven gear to be larger than that of the driving gear. This design utilizes the basic principle of gear transmission; that is, when the diameter of the driven gear is larger than that of the driving gear, a speed reduction and torque increase effect can be achieved.

[0062] Through the above technical solution, the configuration of the driven gear diameter of the bevel gear set 45 being larger than that of the driving gear amplifies the torque transmitted from the shaft 44 to the first rotating rod 41 while reducing the rotational speed. This amplification of torque helps the linkage guiding mechanism 4 overcome airflow resistance or mechanical friction that the guide plate 213 may encounter during adjustment, ensuring that the guide plate 213 can rotate stably and powerfully to the preset angle, thereby achieving precise wind direction control. The reduced rotational speed makes the adjustment process of the guide plate 213 smoother and more precise, avoiding inaccurate positioning or impact caused by excessively fast rotation, thus improving the accuracy and reliability of wind direction adjustment. Therefore, this solution provides more precise and stable wind direction control capabilities, better adapting to the feeding requirements of different materials and improving feeding efficiency and accuracy.

[0063] In some embodiments described above in this application, a lifting-type sequential feeding machine is proposed, which achieves lifting feeding through a feeding mechanism 2 and changes the airflow direction using a linkage guiding mechanism 4. However, in actual operation, how to effectively and accurately coordinate and control the various components of the feeding machine 1 to ensure the automated, efficient, and stable operation of the feeding process is a problem that needs to be solved. The lack of a centralized control unit will lead to complex operation, low efficiency, and difficulty in coping with various changes in working conditions.

[0064] In this application, it is further proposed that a control box 12 is fixedly connected to the top of the frame 1. The control box 12 is a device for integrating and protecting electrical components, control modules, and operating interfaces. Its main function is to provide a centralized control center for the feeding machine 1, realizing automated management and operation of the entire feeding process. Placing the control box 12 at the top of the frame 1 is typically for the convenience of operators to observe, set, and handle emergencies, while also facilitating wiring and heat dissipation, and ensuring its stability during equipment operation. Specifically, the control box 12 may contain a programmable logic controller (PLC), a touch screen human-machine interface (HMI), relays, circuit breakers, frequency converters, power modules, and various sensor interfaces. The PLC is responsible for receiving signals from sensors (such as position sensors and pressure sensors) and controlling the actions of the actuators according to the preset program logic. The HMI provides an intuitive graphical interface for operators to monitor equipment status, adjust operating parameters, and perform fault diagnosis. The control box 12 is typically made of metal or high-strength engineering plastic to provide a good level of protection against dust and moisture intrusion, ensuring the normal operation of the internal electronic components.

[0065] Through the above technical solution, a control box 12 is fixedly connected to the top of the frame 1, providing a centralized and efficient control center for the entire feeding machine 1. The control box 12 integrates various control components and operating interfaces, enabling precise coordination and automated control of all key operations, such as the lifting and lowering of the feeding mechanism 2, horizontal material handling, and the change of airflow direction in the linkage guide mechanism 4. This significantly simplifies the operation process, improves the automation level and operating efficiency of the feeding process, and enhances the stability and reliability of the equipment. Operators can intuitively monitor the equipment status, adjust operating parameters, and promptly handle abnormal situations through the control box 12, effectively solving problems such as operational complexity and low efficiency caused by the lack of centralized control, ensuring that the feeding machine 1 can stably and efficiently complete sequential feeding tasks.

[0066] The following example will provide a more detailed explanation of the above technical solution: In an automated manufacturing plant, a large number of material pallets need to be continuously and reliably supplied to a processing station. Traditionally, operators need to manually place the material pallets one by one into the processing station and manually stack them after processing. This manual operation is not only inefficient and labor-intensive, but also prone to dust accumulation at the bottom of the material pallets during stacking. This dust may fall into the pallets below, affecting the cleanliness of the materials and causing inconvenience for subsequent outbound shipments.

[0067] To solve the above problems, the manufacturing plant introduced a lifting-type sequential feeding machine. The working process of this feeding machine is as follows: First, the main structure of the feeding machine is the frame 1, which is clearly divided into a palletizing area and a feeding area. Inside the palletizing area, multiple detachable pallets 11 are pre-installed vertically. Operators neatly place a batch of pallets 3 of materials to be processed onto these pallets 11, forming a stable stack. This pre-set stacking method avoids the tediousness of manual handling and lays the foundation for automated material handling. Inside the feeding area, vertical guide rails 13 and vertical toothed plates 15 are fixedly connected; these provide support and power for the vertical movement of the feeding mechanism 2. A control box 12 is fixedly connected to the top of the frame 1 for centralized control of the entire feeding process.

[0068] When the processing station requires material pallets, the loading mechanism 2 begins operation. The loading mechanism 2 is movably connected within the loading area, and its core component is the carrying plate 21. A vertical sliding unit is provided at the bottom of the carrying plate 21, which includes a lifting motor 214 and a vertical slider 215. The lifting motor 214 is fixedly connected to the bottom end of the carrying plate 21, and its output shaft is fixedly connected to a gear that matches the vertical gear plate 15. The vertical slider 215 is slidably connected to the vertical guide rail 13. The lifting motor 214 drives the gear to mesh along the vertical gear plate 15, while the vertical slider 215 slides along the vertical guide rail 13, allowing the carrying plate 21 to accurately descend to the height of the uppermost material pallet 3 in the palletizing area. To ensure the smoothness and limit of vertical movement, a vertically arranged vertical traction chain 14 is provided between the bottom of the carrying plate 21 and the bottom of the frame 1.

[0069] A limit baffle 211 is fixedly connected to the top of the loading plate 21 for positioning the material pallet 3 during material handling. A horizontal material handling unit is located on the loading plate 21 and includes a horizontal guide rail 22 fixedly connected to the top of the loading plate 21. A slide block 23 is slidably connected to the top of the horizontal guide rail 22. A transmission motor 291 is fixedly connected to the bottom of the loading plate 21, and its output shaft is driven by a toothed pulley assembly 29. A connecting tooth 231 that meshes with the toothed pulley assembly 29 is fixedly connected to the side of the slide block 23 near the toothed pulley assembly 29. The transmission motor 291 drives the toothed pulley assembly 29, which in turn moves the slide block 23 along the horizontal guide rail 22 towards the stacking area via the connecting tooth 231. A hydraulic cylinder 24 is detachably connected to the slide block 23, and a movable clamp 25 is movably connected to the output end of the hydraulic cylinder 24. When the slide 23 moves above the material pallet 3, the hydraulic cylinder 24 extends, and the movable clamp 25 matches the protrusion fixedly connected to the bottom of the material pallet 3, achieving reliable clamping and traction of the material pallet 3. A horizontal traction chain 28 for limiting is connected between the slide 23 and the carrying plate 21 to ensure the accuracy of horizontal movement. Side plates 26 fixedly connected to the carrying plate 21 are symmetrically arranged on both sides of the slide 23. Multiple guide wheels 27 are rotatably connected to one side of the carrying plate 21 to further ensure the stability of the horizontal movement of the slide 23.

[0070] After clamping the material pallet 3, the conveyor motor 291 reverses its direction, driving the slide block 23 to horizontally pull the material pallet 3 from the palletizing area to above the loading area. At this time, the air blowing box 212 fixedly connected to the top of the carrying plate 21 comes into play. Multiple parallel guide plates 213 are rotatably connected inside the air blowing box 212. The linkage guide mechanism 4 is driven between the loading mechanism 2 and the air blowing box 212. This mechanism includes multiple first rotating rods 41, whose two ends are rotatably connected to the inner wall of the carrying plate 21. Second rotating rods 42 are rotatably connected to the outer wall of the guide plate 213 and the air blowing box 212, and are driven by the first rotating rods 41 through a sprocket set 43. A shaft 44 is rotatably connected to the bottom wall of the inner wall of the carrying plate 21, and a horizontal pulley 46 coaxially fixedly connected to the top of the shaft 44 and driven by the output shaft of the conveyor motor 291. A bevel gear set 45 is provided between the shaft 44 and the first rotating rods 41, and a vertical pulley set 47 is connected between adjacent first rotating rods 41. The bevel gear set 45 consists of a driving gear and a driven gear. The driving gear is coaxially and fixedly connected to the shaft 44, and the driven gear is coaxially and fixedly connected to the first rotating rod 41, with the driven gear having a larger diameter than the driving gear. When the material tray 3 is pulled under the air blowing box 212, the linkage guiding mechanism 4 transmits power from the transmission motor 291 via the horizontal pulley 46, shaft 44, bevel gear set 45, first rotating rod 41, vertical pulley set 47, second rotating rod 42, and sprocket set 43 to precisely change the angle of the guide plate 213, ensuring that the airflow from the air blowing box 212 effectively blows onto the bottom of the material tray 3. Compared to traditional manual cleaning or no cleaning at all, this automatic air blowing cleaning method can efficiently remove dust and impurities from the bottom of the material tray 3, avoiding the risk of dust falling into the next tray and ensuring the cleanliness of the materials.

[0071] After cleaning, hydraulic cylinder 24 releases movable clamp 25, and material tray 3 is placed in the designated position in the loading area. The vertical sliding unit of loading mechanism 2 is activated again, and lifting motor 214 drives the carrying plate 21 to rise, preparing for the next material retrieval. The entire process is centrally controlled by control box 12, realizing automated and continuous loading operation. After the loading operation is completed, as... Figure 8 As shown, the material enters the needle feeding area, where the needle is inserted through the gantry assembly, and finally the material trays are automatically stacked and temporarily stored through the conveyor assembly and the palletizer.

[0072] Through the above implementation methods, the feeding machine achieves automated, sequential, and lifting feeding of material pallets, significantly improving feeding efficiency and reducing manual labor intensity. Simultaneously, the innovative air-blowing box 212 and the linked flow guiding mechanism 4 effectively solve the problem of dust contamination at the bottom of the material pallet, ensuring material cleanliness and improving the overall automation level of the production line and product quality.
