Description

Technical Field

[0001] This invention relates to an automatic feeding system, and more particularly to a combined U-shaped automatic inserting and grabbing motion cutting and feeding eccentric mechanism vibration cleaning and shaking recycling machine, belonging to the field of industrial automation technology. Background Technology

[0002] Currently, most bulk materials in powder, block, and granular form are transported using flexible woven bags, widely used in food, building materials, chemicals, minerals, rubber, plastics, and pharmaceuticals. However, when using these raw materials in production, manual handling or manual-assisted mechanical handling is employed. Generally, in mechanical handling, a hoist lifts the bagged material to the work platform, or a conveyor belt transports it to the work platform. The bagged material is then moved manually from the work platform to the feeding port, where it is manually cut open with a knife, allowing the material to enter the hopper. Manual feeding has the following problems: 1. High labor intensity. Regardless of whether the material is granular or powdery, each bag weighs between 25 and 50 kilograms. 1. Processing different materials: Each production line operates continuously for 24 hours, with material requirements ranging from tens to hundreds of tons. All materials are handled and fed manually, resulting in long working hours. 2. High costs: Each person earns 300-400 yuan per day, increasing product costs. 3. Dust pollution: Both powdered and lumpy materials generate dust, which enters the lungs through the respiratory tract, causing respiratory illness and harming the body. 4. High environmental noise: The workshop temperature is high during operation, and environmental noise levels are consistently between 80 and 90 decibels. High decibel levels damage physical and mental health, causing annoyance, anxiety, and affecting mood. 5. Low work efficiency: Human physical strength is always limited; prolonged heavy physical labor leads to fatigue, and work efficiency exhibits diminishing marginal returns.

[0003] In addition, the flexible woven bags are easy to fold at the corners, and the friction between the inner wall and the material generates static electricity, causing a small amount of material to adhere to the inner wall of the flexible woven bags. Simply shaking the woven bags cannot completely remove the residual material, and a small amount of material is easily left behind, resulting in waste. The open space of the shaking area can easily cause dust to float in the workshop air, causing secondary pollution.

[0004] Secondly, during transportation, the relative movement of materials within the flexible woven bag generates static electricity. Powder or small particles adhere to the inner wall of the flexible woven bag, causing the material to discharge momentarily as it flows out of the bag, producing a crackling sound. Summary of the Invention

[0005] The purpose of this invention is to provide a combined U-shaped automatic inserting and grabbing mobile cutting and feeding eccentric mechanism vibration cleaning and shaking recycling machine to solve the problems of long working time, high labor intensity, low efficiency, high labor cost, high dust pollution, and high noise in manual material handling. During material handling, the relative movement of materials in the flexible woven bag generates static electricity, and powder or small particles are adsorbed on the inner wall of the flexible woven bag, resulting in some material remaining in the flexible woven bag. In addition, the flexible woven bag is easy to fold at the corners, and the force is uneven when manually tilting, causing material to remain.

[0006] The technical solution is as follows: A combined U-shaped automatic inserting and grabbing mobile bag-cutting and feeding eccentric vibration cleaning and shaking recycling machine, comprising a frame, a mobile frame, a combined U-shaped automatic inserting and grabbing mechanism, a bag-cutting and feeding mechanism, an eccentric vibration shaking mechanism, and a recycling machine. Multiple rows and columns of multi-layered material bag stacks are arranged between two conveying tracks near the ground on the frame. Each layer contains multiple rows and columns of multi-layered material bags, forming a material bag stack. A conveying track is located at the upper part of the frame away from the ground. The mobile frame moves along the conveying track, and drive rollers on the mobile frame reciprocate along the conveying track, positioned by a position sensor. When the mobile frame reaches the location of the material bag stack, it is fixedly connected to the combined U-shaped automatic inserting and grabbing mechanism. The mobile frame moves horizontally on the conveying track, the combined U-shaped automatic inserting and grabbing mechanism stops moving, and the automatic inserting and grabbing fingers move vertically downwards under the drive of a telescopic mechanism. When close to the material bag, the telescopic lifting frame stops moving, and the automatic inserting and grabbing fingers rotate under the drive of a rotary motor. The automatic gripping fingers enter the material bag from opposite ends. In operation, the paired fingers combine into a U-shape. A telescopic lifting frame moves the fingers vertically, simultaneously moving multiple rows of material bags. The lifting frame stops at a set position. Driven by the power system, the combined U-shaped automatic gripping mechanism moves multiple material bags on the frame towards the cutting and feeding mechanism. When the material bags reach the cutting blade position, the blade separates them, allowing the material to flow out through the cut into the hopper. Simultaneously, an eccentric vibrating shaking mechanism repeatedly beats the material bags suspended on the fingers, cleaning the material adhering to the inner wall. The fingers then rotate, causing empty material bags to fall from the fingers and into the recycling bin. The rotation direction of the corner motor is opposite to the rotation direction of the fingers as they enter the material bag.

[0007] The aforementioned combined U-shaped automatic inserting and grabbing mobile cutting and feeding eccentric mechanism vibration cleaning and shaking recycling machine, the combined U-shaped automatic inserting and grabbing mechanism includes a mobile frame, a telescopic lifting frame, a fixed frame, automatic inserting and grabbing fingers, and a rotary motor.

[0008] The mobile frame has rollers at its bottom, which travel on a conveyor track on the frame. One end of the telescopic lifting frame is connected to the mobile frame, and the other end is connected to the fixed frame. The fixed frame is equipped with automatic gripping fingers and a corner motor. The corner motor can rotate both clockwise and counterclockwise, driving the automatic gripping fingers to rotate synchronously. During operation, the automatic gripping fingers pierce through the material bag and enter the bag. The fixed frame has multiple rows and columns of automatic gripping fingers and corner motors, with the automatic gripping fingers arranged in pairs. Driven by a rotary motor, the automatic gripping fingers move towards each other when gripping material bags. The pairs of automatic gripping fingers combine to form a U-shape. The automatic gripping fingers penetrate the material bag and enter the bag, hooking it in place. When the empty bag detaches from the automatic gripping fingers, the rotary motor rotates, causing the automatic gripping fingers to move relative to each other. Each material bag is gripped by two or more pairs of automatic gripping fingers simultaneously, ensuring that the material bag remains horizontal when rising. Multiple rows and columns of automatic gripping fingers can grip multiple material bags simultaneously.

[0009] The aforementioned combined U-shaped automatic inserting and grabbing motion cutting and feeding eccentric mechanism vibration cleaning and shaking recycling machine includes a cutting and feeding mechanism comprising multiple cutters and a cutting shaft. Multiple cutters are fixedly installed on the cutting shaft, and the cutting shaft is perpendicular to the direction of the conveying track. The material in the material bag is subjected to a force in the same direction as the material bag and the material's own weight, and the material can only move in the forward direction and fall into the designated position.

[0010] The aforementioned combined U-shaped automatic inserting and grabbing motion cutting and feeding eccentric mechanism vibration cleaning and shaking recycling machine includes an eccentric vibration shaking mechanism with a reduction motor, a rotating wheel, an eccentric connecting rod, and a shaking rod. Multiple eccentric connecting rods are mounted on the eccentric connecting rod. The reduction motor drives the rotating wheel to rotate, and the eccentric connecting rod is fixed to the rotating wheel. The reciprocating motion of the eccentric connecting rod drives the reciprocating motion of the shaking rod to beat the material bag, causing residual material on the inner wall of the material bag to fall off. Simultaneously, the shaking rod can eliminate static electricity generated by friction between the material bag and the material. The shaking rod is a good conductor and is connected to the negative terminal of the ground.

[0011] The rotation angle of the automatic inserter is 0° when it is not in operation, positive when it is inserted into the material bag, and negative when it is detached from the material bag.

[0012] The beneficial effects of this invention are as follows.

[0013] 1. The automatic gripping fingers are paired together in a U-shape. Multiple pairs of automatic gripping fingers grip the material bags on the same horizontal plane. Multiple rows and columns of material bags are located on the same layer and on the same horizontal plane.

[0014] 2. It can grab multiple material bags at the same time and cut multiple material bags at the same time, and can grab multiple bags at a time, resulting in high work efficiency.

[0015] 3. The material in the material bag is subjected to a force in the same direction as the material bag and the weight of the material itself. The material can only move in the forward direction and fall into the hopper.

[0016] 4. The cutting and feeding process is carried out in a closed space, so there will be no dust drifting into the outdoor space and no dust pollution.

[0017] 5. The eccentric mechanism vibration cleaning and shaking device adsorbs the static electricity generated by the movement of materials and cleans the materials adhering to the inner wall of the material bag. Attached Figure Description

[0026] A combined U-shaped automatic inserting and grabbing mechanism, a bag-cutting and feeding mechanism, an eccentric vibration shaking mechanism, and a recycling machine are disclosed. The machine includes a frame 1, a conveyor frame 2, a combined U-shaped automatic inserting and grabbing mechanism, a bag-cutting and feeding mechanism, an eccentric vibration shaking mechanism, and a recycling machine. Multiple rows and columns of multi-layered material bags 3 are arranged on the frame 1 near the ground and between two tracks. Above the frame 1, away from the ground, two parallel tracks are provided, with the material bags 3 positioned between them. Rollers are mounted on the conveyor frame 2, which reciprocates on the tracks on the frame 1 under power. The combined U-shaped automatic inserting and grabbing mechanism is fixedly connected to a movable frame 13 and moves accordingly. The combined U-shaped automatic inserting and grabbing mechanism includes a telescopic lifting frame 4 and a fixed frame. 6. Automatic gripping fingers 5 and corner motors 7: The fixed frame 6 is equipped with multiple rows and columns of automatic gripping fingers 5 and corner motors 7. The automatic gripping fingers 5 are arranged in pairs. When each pair of automatic gripping fingers 5 reaches the position of the material bag 3 under the drive of the corner motor 7, it is positioned by a position sensor. The combined U-shaped automatic gripping mechanism stops moving. The automatic gripping fingers 5 move vertically downward under the drive of the telescopic lifting frame 4. When they approach the material bag 3, they move towards each other while gripping the material bag 3. The pairs of automatic gripping fingers 5 are combined into a U-shape. Under the drive of the corner motor 7, the corner motor 7 rotates at a 45-degree angle, and the automatic gripping fingers 5 penetrate the material bag 3 and enter the material bag. Inside bag 3, material bags 3 are hooked. Each material bag 3 has three pairs of automatic gripping fingers 5 that grip it simultaneously, ensuring that the material bag 3 is horizontal when it rises. The telescopic lifting frame 4 drives the automatic gripping fingers 5 to move vertically, causing multiple rows and columns of material bags 3 to move upwards simultaneously. The telescopic lifting frame 4 stops rising when it reaches a set position. The combined U-shaped automatic gripping mechanism drives the material bags 3 on the frame 1 towards the bag cutting and feeding mechanism. The bag cutting mechanism includes five cutters 8 and a cutter shaft. The five cutters 8 are fixedly installed on the cutter shaft. When the material bag 3 moves to the position of the cutter 8 set by the bag cutting and feeding mechanism, the cutter 8 separates the material bag 3 and cuts a long slit from the bottom of the material bag 3. The material in the material bag 3 flows out from the cut slit. Upon entering the hopper, the material in the material bag 3 is subjected to a force acting in the same direction as the material bag 3, as well as its own weight. The material's trajectory is a parabola, meaning it can only move in the forward direction and fall into the designated position. The eccentric vibration shaking mechanism is equipped with a reduction motor 9, a rotating wheel 10, an eccentric connecting rod 11, and a shaking rod 12. The eccentric connecting rod 11 drives the shaking rod 12 to reciprocate. Simultaneously, the eccentric vibration shaking mechanism reciprocates and taps the material bag 3 suspended on the automatic gripper finger, cleaning the material adhering to the inner wall of the material bag 3. The reduction motor 9 drives the rotating wheel 10 to rotate, and the eccentric connecting rod 11 is fixed to the rotating wheel 10. The reciprocating motion of the eccentric connecting rod 11, in turn, drives the shaking rod 12 to reciprocate and tap the material bag 3, causing the remaining material on the inner wall of the material bag 3 to fall off.Simultaneously, the shaking rod 12 eliminates static electricity generated by friction between the material bag 3 and the material. The shaking rod 12 is a conductor and grounded to the machine housing on the frame 1. At the same time, when the empty material bag 3 detaches from the automatic gripper finger 5, the automatic gripper finger 5 moves relative to the material bag 3. Driven by the angle motor 7, the automatic gripper finger 5 rotates at a negative 45-degree angle. This negative 45-degree rotation of the angle motor 7 represents the angle at which the automatic gripper finger 5 detaches from the material bag 3. The empty material bag 3 is then retrieved from the automatic gripper finger. 5. The rotation direction of the corner motor 7 is opposite to the rotation direction of the automatic gripper finger 5 as it inserts into the material bag 3, completing one cycle of automatic gripping, cutting, residual material removal, and recycling of the material bag 3. The conveyor frame 2 moves on the frame 1, reaching the position to grip the material bag 3, and repeats the above actions. When an empty material bag 3 is detected on the material bag 3 rack, the empty trolley leaves the working position, and the trolley loaded with material bags 3 enters the working position to wait. This process repeats continuously. Example 2

The machine includes a frame 1, a conveyor frame 2, a combined U-shaped automatic inserting and grabbing mechanism, a bag-cutting mechanism, an eccentric vibration shaking mechanism, and a recycling machine. Multiple rows and columns of multi-layered material bags 3 are arranged on the frame 1 near the ground and between two tracks. Above the frame 1, away from the ground, two parallel tracks are provided, with the material bags 3 positioned between them. Rollers are mounted on the conveyor frame 2, which reciprocates on the tracks on the frame 1 under power. The combined U-shaped automatic inserting and grabbing mechanism is fixedly connected to a movable frame 13 and moves accordingly. The combined U-shaped automatic inserting and grabbing mechanism includes a telescopic lifting frame 4, a fixed frame 6, and a self-propelled... The fixed frame 6 is equipped with multiple rows and columns of automatic gripping fingers 5 and corner motors 7. The automatic gripping fingers 5 are arranged in pairs. When each pair of automatic gripping fingers 5 reaches the position of the material bag 3 under the drive of the corner motor 7, it is positioned by a position sensor. The combined U-shaped automatic gripping mechanism stops moving. The automatic gripping fingers 5 move vertically under the drive of the telescopic lifting frame 4. When they approach the material bag 3, they move towards each other to grab the material bag 3. The pairs of automatic gripping fingers 5 are combined into a U-shape. Under the drive of the corner motor 7, the corner motor 7 rotates 60 degrees, and the automatic gripping fingers 5 penetrate the material bag 3 and enter the material bag 3. The material bag 3 is hooked, and each material bag 3 has three pairs of automatic gripping fingers 5 that grip it simultaneously, ensuring that the material bag 3 is in a horizontal state when it rises. The telescopic lifting frame 4 drives the automatic gripping fingers 5 to move in the vertical direction, driving multiple rows and columns of material bags 3 to move upwards simultaneously. The telescopic lifting frame 4 stops rising when it reaches the set position. The combined U-shaped automatic gripping mechanism drives the 5 material bags 3 on the frame 1 to move towards the cutting and feeding mechanism. The cutting mechanism includes 10 cutters 8 and a cutting shaft. The 10 cutters 8 are fixedly installed on the cutting shaft. When the material bag 3 moves to the position of the cutter 8 set by the cutting and feeding mechanism, the cutter 8 separates the material bag 3 and cuts a long slit from the bottom of the material bag 3. The material in the material bag 3 flows out from the cut slit. In the feeding hopper, the material in the material bag 3 is subjected to a force in the same direction as the material bag 3 and its own weight. The material's trajectory is a parabola, and it can only move in the forward direction and fall into the designated position in the hopper. The eccentric vibration shaking mechanism is equipped with a reduction motor 9, a rotating wheel 10, an eccentric connecting rod 11, and a shaking rod 12. The eccentric connecting rod 11 drives the shaking rod 12 to achieve reciprocating motion. At the same time, the eccentric vibration shaking mechanism reciprocates to beat the material bag 3 suspended on the automatic gripper finger, cleaning the material adhering to the inner wall of the material bag 3. The reduction motor 9 drives the rotating wheel 10 to rotate, and the eccentric connecting rod 11 is fixed on the rotating wheel 10. The reciprocating motion of the eccentric connecting rod 11 drives the reciprocating motion of the shaking rod 12 to beat the material bag 3, causing the remaining material on the inner wall of the material bag 3 to fall off.Simultaneously, the shaking rod 12 eliminates static electricity generated by friction between the material bag 3 and the material. The shaking rod 12 is a conductor and is grounded to the machine housing on the frame 1. At the same time, when the empty material bag 3 detaches from the automatic gripper finger 5, the automatic gripper finger 5 moves relative to the material bag 3. Driven by the angle motor 7, the automatic gripper finger 5 rotates by a negative 60-degree angle. This negative 60-degree rotation of the angle motor 7 represents the angle at which the automatic gripper finger 5 detaches from the material bag 3. The empty material bag 3 is then retrieved from the automatic gripper finger. 5. The rotation direction of the corner motor 7 is opposite to the rotation direction of the automatic gripper finger 5 as it inserts into the material bag 3, completing one automatic gripping, cutting, residual material removal, and recycling process of the material bag 3. The conveyor frame 2 moves on the frame 1, reaching the position to grip the material bag 3, and repeats the above actions. When an empty material bag 3 is detected on the material bag 3 rack, the empty trolley leaves the working position, and the trolley loaded with material bags 3 enters the working position to wait. This process is repeated.
