Description

Technical Field

[0001] This invention relates to the field of packaging technology, and more specifically to an automatic packaging device for electrolytic anode powder. Background Art

[0002] In the electrolytic aluminum production process, the anode workshop produces a large amount of finished powder. After being precisely discharged through the feeding pipe, this powder is packaged into bags for subsequent storage, sales, or reserve use.

[0003] When packaging powder, once the powder is filled, the next step is to seal the packaging bag tightly to prevent the powder from scattering or leaking during transportation or storage. To achieve this, before sealing, the two sides of the bag opening must be folded inward and pressed tightly to ensure a tight seal, preparing for the subsequent sealing process.

[0004] Traditional sealing methods typically use clamps with heat-sealing devices. These clamps hold the bag opening closed while the heat-sealing device melts the opening to seal it. However, this type of packaging bag, sealed by heat sealing with clamps, has a straight seal with weak local sealing strength, making it prone to leakage during subsequent handling.

[0005] Therefore, we need to design a new packaging device to avoid the problems of low local sealing strength and easy leakage that exist when using existing hot melt devices for clamping and hot melt sealing packaging. Summary of the Invention

[0006] The present invention aims to provide an automatic packaging device for electrolytic anode powder to solve the problem of low local sealing strength and easy leakage when using existing hot-melt devices for clamping and hot-melt sealing packaging.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an automatic packaging device for electrolytic anode powder, comprising a frame, a feeding pipe on the frame, the frame including a fixed frame and a flipping frame rotatably connected to the upper end of one side of the fixed frame; the feeding pipe is fixed on the flipping frame, and the fixed frame is provided with a packaging table and a sealing mechanism;

[0008] The sealing mechanism is used to secure arc-shaped ties to the opening of a packaging bag. The sealing mechanism includes a support platform and a pair of symmetrically distributed swing arms. The middle of the two swing arms is rotatably connected to the support platform. One end of each swing arm is fixedly connected to an arc-shaped clamp. The end of the swing arm connected to the clamp is the clamping end, and the other end is the driving end. The clamp is located above the support platform. A notch is provided on one side edge of the support platform, and the notch is located between the two clamps. The swing arms are connected to a swing drive unit, which is used to drive the driving end of the swing arm to swing and make the two clamps abut against each other. The driving end of the two swing arms is also connected to a reset component, and the middle of the two swing arms is far apart from each other, while the two ends are close to each other.

[0009] The principle and advantages of this solution are as follows: In this invention, the binding nails used are iron nails, which have a certain strength and hardness. By using a binding mechanism, the arc-shaped binding nails can be bound to the opening of the packaging bag. Compared with the traditional heat-sealing method, this binding sealing method can effectively prevent leakage caused by insufficient sealing strength at the sealing part, because the opening of the packaging bag is folded and gathered together during the binding sealing process, and the opening is tightened by the binding nails. Specifically, the tying studs are pre-placed at the notch of the support platform. Once the bag opening enters the notch, it is positioned within the arc-shaped tying stud. The swing arm, driven by the swing drive unit, swings. Since the middle of the swing arm is positioned on the support platform, the clamping end of the swing arm swings in the opposite direction to the drive end under the action of leverage. This causes the two clamps to move towards each other and abut against each other. During the movement of the clamps, the two ends of the arc-shaped tying stud at the notch are squeezed inwards, changing the stud from an arc shape to a ring shape, thus automatically tying and sealing the bag opening. This structure enables automatic tying and sealing of the bag opening without manual tying, improving the efficiency and quality of packaging sealing.

[0010] The reset component connected to the drive end of the two swing arms is used to reset the swing arms after they swing. The middle parts of the two swing arms are far apart from each other, while the two ends are close to each other, which makes the swing arms bend. In this way, the two ends of the swing arms can swing in opposite directions under the action of the lever, which facilitates the control of the clamp.

[0011] Meanwhile, the frame in this solution includes a fixed frame and a flipping frame rotatably connected to the upper side of the fixed frame. This allows the flipping frame to be flipped on the fixed frame. When it is necessary to fill the packaging bag, the flipping frame is flipped to be placed horizontally above the fixed frame, so that the discharge pipe opening is directly facing the packaging table below, which facilitates filling the packaging bag on the packaging table. When it is necessary to remove the finished packaging bag or place a new packaging bag, the flipping frame can be flipped to move the flipping frame away from above the packaging table, thereby opening up the space above the fixed frame to facilitate the removal of the packaging bag.

[0012] The advantages of this solution are:

[0013] 1. The traditional heat-sealing method replaces the traditional strapping seal with a strapping seal. This strapping seal achieves a high-strength seal by overlapping and gathering the bag openings together during sealing, and further tightening the bag openings with strapping nails. The sealing effect is good and it is not easy to leak. This avoids the problems of low local sealing strength and easy leakage that exist in straight seals.

[0014] 2. This technology enables automatic strapping of curved strapping nails, eliminating the need for manual strapping and packaging, thus improving the packaging efficiency and sealing quality of the device.

[0015] 3. The flipping frame can be flipped on the fixed frame, which makes it easy to fill the packaging bags and to pick up and put away the packaging bags.

[0016] Preferably, as an improvement, the swing drive unit includes a drive cylinder fixed on the support platform, and a swing control component is connected to the cylinder rod of the drive cylinder, the swing control component being located between two swing arms;

[0017] The swing control component is a wheel that is rotatably connected to the cylinder rod of the drive cylinder. There is one wheel, and the wheel simultaneously abuts against two swing arms; or there are two sets of wheels symmetrically distributed, and the two sets of wheels abut against two swing arms respectively.

[0018] Alternatively, the swing control component is a wedge block that is fixedly connected to the cylinder rod of the drive cylinder. The diameter of the end of the wedge block facing the notch is larger than that of the other end. Both ends of the wedge block are provided with wedge surfaces, and the wedge surfaces abut against the drive ends of the two swing arms.

[0019] Alternatively, the swing control component includes a rack fixedly connected to the cylinder rod of the drive cylinder, a gear meshing on the rack, a double-ended lead screw fixedly connected to the gear on the same axis, a sliding sleeve sleeved and threadedly connected to both ends of the double-ended lead screw, the sliding sleeve being slidably mounted on the support platform along the axial direction of the double-ended lead screw, and a push block fixedly connected to the sliding sleeve, the two push blocks abutting against the two swing arms respectively.

[0020] Through the above scheme, the swing control component is used to move linearly under the drive of the drive cylinder and abut against different parts of the swing arm drive end, thereby realizing the control of different swing degrees of the swing arm, and thus realizing the automatic swing control of the clamp.

[0021] When the swing control component is a wheel, the wheel is driven by a cylinder to move, causing the wheel to push against the swing arm and swing. While controlling the swing arm's swing, the wheel can also rotate on the swing arm, reducing friction during contact and improving the wheel's control over the swing arm's swing. When there is one wheel, it pushes against two swing arms simultaneously, allowing them to swing synchronously. This enables the two clamps to simultaneously press the ends of the binding nail inward, improving the quality of the knot. When there are two sets of wheels, each set pushes against one swing arm, reducing the need for a large wheel diameter and facilitating assembly and installation.

[0022] When the swing control component is a wedge, the wedge is driven by a drive cylinder to move, causing the wedge to push against the two swing arms to swing. Compared with the wheel's pushing structure and method, the wedge surface of the swing control component has a larger area to contact the swing arms, which is more conducive to the swing control of the swing arms.

[0023] When the swing control component is a rack, pinion, double-ended lead screw, sliding sleeve, and push block, the transmission of the rack and pinion mechanism and the lead screw mechanism enables the drive cylinder to drive the push block to move laterally and push against the swing arm, so that the swing arm swings. In this swing control method, since the push block does not follow the cylinder rod of the drive cylinder to move linearly along the axial direction of the cylinder rod, but only moves linearly along the radial direction of the cylinder rod in its original position, the contact and friction area between the swing arm and the swing control component is smaller, which can reduce the area of ​​wear caused by the swing control component to the swing arm and help extend the service life of the swing arm.

[0024] Preferably, as an improvement, the support platform is provided with a nailing position; a push handle is fixedly connected to the cylinder rod of the drive cylinder, the nailing position is located between the notch and the push handle and is located on the moving path of the push handle, and the push handle is used to push the binding nail from the nailing position to the notch.

[0025] The above solution uses a mounting position to hold ready-to-use ties. When the drive cylinder operates, the push handle moves, automatically pushing the ties in the mounting position to the notch for use in tying. This achieves automatic ties pushing. The mounting position makes ties placement more convenient, avoiding the risk of ties falling out of the notch or the operator being injured by the clamp, which is common when ties are placed directly at the notch. This design improves practicality.

[0026] Preferably, as an improvement, the binding mechanism further includes a nail holder for storing binding nails, the nail holder being fixed on a support platform, the nail holder having a horizontal part and a vertical part connected to each other, with a smooth transition between the horizontal and vertical parts, the vertical part being located directly above the nail mounting position; a pusher head is also slidably provided on the horizontal part of the nail holder, the pusher head being used to push the binding nail to move along the nail holder, and a compression spring is connected between the pusher head and the nail holder.

[0027] The above solution uses a nail holder to arrange and hold ready-to-use ties, eliminating the need to add a new ties after each tying is completed. This allows for continuous packaging operations and is more convenient for actual production. The ties pusher head pushes the ties arranged on the nail holder forward, moving them from a horizontal to a vertical position, where they automatically fall to their designated nailing positions. This automatic nailing eliminates the need for manual pushing, further facilitating production. A compression spring applies continuous pressure to the pusher head, ensuring it continuously moves the ties.

[0028] Preferably, as an improvement, the device further includes a lifting cylinder, the cylinder seat of the lifting cylinder is rotatably connected to the fixed frame, the cylinder rod is rotatably connected to a mounting plate, the mounting plate is rotatably connected to the fixed frame, and a control cylinder is fixedly mounted on the mounting plate, the cylinder rod of the control cylinder is fixedly connected to the cylinder seat of the drive cylinder.

[0029] Through the above scheme, the lifting cylinder can flip the mounting plate, the control cylinder on the mounting plate, and the sealing mechanism connected to the control cylinder, allowing the sealing mechanism to be in a vertical position for standby and a horizontal position for use. This allows the sealing mechanism to be turned vertically when the packaging bag needs to be removed from above, ensuring that the sealing mechanism does not obstruct the removal of the packaging bag. At the same time, it makes it easier to store the sealing mechanism when the equipment is not in use, reducing the width of the equipment and facilitating storage. The control cylinder is used to move the sealing mechanism, allowing it to be moved to the opening of the packaging bag for sealing, and after sealing, it retracts away from the packaging bag to facilitate the removal of the packaging bag and the packaging of the next bag.

[0030] Preferably, as an improvement, the flipping frame is equipped with a swing cylinder and a pair of swing grippers. The cylinder seat of the swing cylinder is rotatably connected to the flipping frame, and the cylinder rod is rotatably connected to the swing grippers. The two swing grippers are used to squeeze and close the bag opening of the packaging bag. The swing grippers are rotatably connected to the outer wall of the feeding tube, and the two swing grippers can abut against each other when they are at the lowest point of the swing path.

[0031] One of the swing grippers is provided with a front closing unit and the other swing gripper is provided with a rear closing unit; both the front closing unit and the rear closing unit include a translation drive, the translation drive is fixedly connected to the translation gripper, and the translation drive is used to drive the translation gripper to translate along the length direction of the swing gripper.

[0032] The translation drive component includes a translation screw, a sliding sleeve, and a drive motor. The two ends of the translation screw are rotatably connected to the swing gripper. The drive motor is fixed to the swing gripper. The drive motor is connected to the translation screw and is used to drive the translation screw to rotate. The sliding sleeve is sleeved on the translation screw and is threaded to the translation screw. The sliding sleeve is fixedly connected to the translation gripper, and the sliding sleeve is laterally slidably connected to the swing gripper.

[0033] Alternatively, the translation drive component is a translation cylinder, which is fixed on the swing gripper, and the cylinder rod of the translation cylinder is fixedly connected to the translation gripper.

[0034] In the above scheme, the swing cylinder drives the swing grippers to swing, so that when the two swing grippers swing downward from the side of the feed tube, they can close together to squeeze and close the bag opening in the left and right directions. The translation drive is used to drive the translation grippers to move, so that the two translation grippers can move towards each other and squeeze and close the bag opening in the front and back directions. In this way, the purpose of closing the bag opening in four directions is achieved. Compared with the traditional clamp closing method, this four-way closing operation makes the side walls of the bag opening fold and gather together, so that the bag opening has a smaller width. This makes it easier to tie the bag opening with ties, thus better meeting the needs of ties for bag opening. Moreover, after ties are tied, leakage is less likely to occur, improving the sealing effect.

[0035] When the translation drive includes a translation screw, a sliding sleeve, and a drive motor, the rotation of the translation screw causes the sliding sleeve to slide on the translation screw, thereby causing the sliding sleeve to drive the translation gripper to move. The translation screw has a guiding effect on the movement of the sliding sleeve and the translation gripper, enabling the translation gripper to move horizontally in a predetermined direction with higher movement accuracy.

[0036] When the translation drive is a translation cylinder, the translation gripper is moved directly by the cylinder, which has the advantages of fast response speed, simple structure and easy maintenance and control.

[0037] Preferably, as an improvement, the swing gripper includes a base and two parallel layers of clamping plates. The base has vertically extending adjustment holes on its side edges. The clamping plates are detachably and fixedly connected to the adjustment holes. There is a gap between the two layers of clamping plates, forming a sealing cavity that runs through the front and rear. The translation gripper is C-shaped. The translation gripper and the translation drive are both located between the two layers of clamping plates, and the translation drive can drive the translation gripper to enter and exit the sealing cavity.

[0038] Through the above scheme, two layers of clamps are used to squeeze and seal the top and bottom of the bag opening, thereby improving the sealing effect and quality. Simultaneously, after clamping the bag opening, the two layers of clamps provide upward and downward traction, making it easier to seal the bag opening through the sealing chamber. The clamps are detachably fixed to the base via adjustment holes, allowing the clamps to be fixed at different positions. This changes the height of the clamps on the base, thus adjusting the distance between the two clamps. This makes the clamping and traction positions of the two clamps on the bag opening adjustable, improving practicality and facilitating disassembly and maintenance. Furthermore, the C-shaped sliding jaws provide forward and backward squeezing and sealing to both the top and bottom of the bag opening, working in conjunction with the swinging jaws to further improve the sealing effect and quality. By placing the translational grippers and the translational drive between the two clamping plates, the translational grippers can enter and exit the sealing cavity when the translational drive drives the translational grippers to move horizontally. Furthermore, when the two translational grippers move relative to each other, the distance between them can become smaller or even cancel each other out. This further reduces the width of the bag opening when closing the bag, making it easier to tie with wire and improving the closing effect and quality of the bag.

[0039] Preferably, as an improvement, the device further includes a receiving mechanism on the feeding pipe. The receiving mechanism includes two sets of symmetrically arranged arc-shaped hoops. The feeding pipe is located between the two sets of arc-shaped hoops. The two sets of arc-shaped hoops can be joined together to form a ring that fits onto the lower end of the feeding pipe. The shape and curvature of the arc-shaped hoops match the outer wall of the feeding pipe. A mounting frame is fixed on the outer wall of the feeding pipe. Each set of arc-shaped hoops is rotatably connected to a clamping arm. The end of the clamping arm away from the arc-shaped hoops is rotatably connected to the mounting frame. A telescopic cylinder is provided between the two sets of clamping arms. The cylinder rod and cylinder seat of the telescopic cylinder are rotatably connected to the two sets of clamping arms respectively, and the two ends of the arc-shaped hoops are symmetrically arranged.

[0040] By setting up arc-shaped hoops, the opening of the packaging bag can be fixed. Specifically, when material needs to be received, the operation of the telescopic cylinder can cause the clamping arm to swing, causing the two sets of arc-shaped hoops to join together. After the two arc-shaped hoops are joined, they form a ring that fits on the outer wall of the feeding pipe, thereby pressing and fixing the opening of the packaging bag to the outer wall of the feeding pipe. Thus, there is no need for manual pulling of the packaging bag opening for material receiving. Under the pressing action of the arc-shaped hoops, the opening of the packaging bag and the discharge port fit together without gaps, so that powder will not escape from the opening of the packaging bag during the material receiving process, avoiding material waste and damage to the processing environment, and is more conducive to the health of operators.

[0041] Meanwhile, the clamping arms of the two sets of arc-shaped clamps are driven to swing through the same telescopic cylinder. This reduces the control source and simplifies the system structure while ensuring the synchronous movement of the two sets of arc-shaped clamps. This allows the two sets of arc-shaped clamps to simultaneously press and fix the packaging bag at the feeding pipe, which is more conducive to the fit between the bag opening and the feeding pipe. Furthermore, the two ends of the arc-shaped clamps are symmetrically arranged, so that both ends of the arc-shaped clamps can be driven to move and press against the feeding pipe simultaneously. This ensures that the force on both ends of the arc-shaped clamps is even, which is more conducive to preventing powder from escaping.

[0042] Preferably, as an improvement, both ends of the arc-shaped hoop are fixedly connected to abutment portions, and clamping arms are connected to the abutment portions; the abutment portions at both ends of one set of arc-shaped hoops abut against the abutment portions at both ends of another set of arc-shaped hoops; an auxiliary connecting arm is connected between the abutment portion and the mounting frame, and the two ends of the auxiliary connecting arm are rotatably connected to the abutment portion and the mounting frame respectively; a transmission rod is provided between the two auxiliary connecting arms connected at both ends of the same arc-shaped hoop, and the transmission rod is rotatably connected to the two auxiliary connecting arms respectively.

[0043] The above design facilitates the connection between the curved hoop and the clamping arm, eliminating the need for the clamping arm to be directly connected to the curved hoop. This ensures the curved hoop has a suitable area to stably press and fix the bag opening at the feed pipe, preventing the curved hoop from having too small a squeezing area on the bag opening and affecting the fixing effect. The auxiliary connecting arm assists the clamping arm in swinging, ensuring the telescopic cylinder can more effectively control the swing of the clamping arm. The transmission rod design allows the two auxiliary connecting arms to move synchronously, enabling the clamping arms at both ends of the curved hoop to move synchronously, thus controlling the synchronous movement of both ends of the curved hoop and further enhancing the stable fixing of the packaging bag by the curved hoop.

[0044] Preferably, as an improvement, the device further includes a traction mechanism, which includes multiple traction brackets fixed on the tilting frame. The multiple traction brackets are evenly distributed on the outer periphery of the feed tube. Each traction bracket includes a base plate fixed on the tilting frame. The base plate is provided with a traction cylinder, a traction arm, and a locking plate. The locking plate is fixed on the base plate. The cylinder seat of the traction cylinder and the middle part of the traction arm are rotatably mounted on the base plate. One end of the traction arm is rotatably connected to the cylinder shaft of the traction cylinder. The end of the traction arm connected to the traction cylinder is provided with a clearance groove for the cylinder shaft. The other end of the traction cylinder is fixedly connected with a hook. The free end of the hook can abut against the locking plate. Multiple clamps are provided on the outer wall of the feed tube. The multiple clamps are evenly distributed on the outer wall of the feed tube.

[0045] Through the above scheme, during the receiving and packaging process of the packaging bag, due to its flexibility, the bag needs to be stretched and pulled during the receiving process to ensure that the powder can smoothly enter the bag, effectively opening the interior of the bag to facilitate powder entry. The traction mechanism in this scheme is used to pull the packaging bag, thus facilitating powder reception. When pulling the bag, the end of the bag is suspended on a hook, and the traction cylinder controls the swing of the traction arm, causing the hook to swing. This causes the hook to abut against the locking plate, which locks the end of the hook, preventing the bag from slipping off and ensuring effective traction. This, in turn, allows the bag to effectively receive and fill the powder. Multiple traction mechanisms simultaneously pull and suspend the bag from multiple directions, resulting in better traction and allowing the interior of the bag to be fully opened for receiving. Clamps are used to hold and fix the bag opening to the outer wall of the feeding tube, further securing the bag opening. Attached Figure Description

[0064] Example 1

[0065] The automatic packaging device for electrolytic anode powder in this embodiment, such as Figure 1As shown, the machine includes a frame 1, on which a feeding pipe 4 is provided. The frame 1 includes a fixed frame 2 and a flipping frame 3 rotatably connected to the upper end of one side of the fixed frame 2. A flipping cylinder 5 is connected between the fixed frame 2 and the flipping frame 3. The cylinder seat of the flipping cylinder 5 is rotatably connected to the fixed frame 2, and the cylinder rod is rotatably connected to the flipping frame 3. The feeding pipe 4 is fixed at the middle position of the flipping frame 3. The fixed frame 2 is provided with a packaging table 6 and a sealing mechanism 7.

[0066] The sealing mechanism 7 is used to secure the curved ties 8 to the opening 61 of the packaging bag 60, such as... Figures 2 to 4 As shown, the tying mechanism 7 includes a support platform 9 and a pair of symmetrically distributed swing arms 10. The middle of the two swing arms 10 is rotatably connected to the support platform 9. One end of each swing arm 10 is fixedly connected to an arc-shaped clamp 11. The end of the swing arm 10 connected to the clamp 11 is the clamping end 12, and the other end is the driving end 13. The clamp 11 is located above the support platform 9. The support platform 9 has a notch 14 on one edge near the clamp 11. The notch 14 is used to hold the arc-shaped binding nail 8 for tying. The notch 14 is located between the two clamps 11. The swing arm 10 is connected to a swing drive unit. The swing drive unit is used to drive the driving end 13 of the swing arm 10 to swing and make the two clamps 11 abut against each other. The driving end 13 of the two swing arms 10 is also connected to a reset member 15. In this embodiment, the reset member 15 is a tension spring. The two ends of the tension spring are respectively connected to the ends of the two swing arms 10. Furthermore, in this embodiment, the two swing arms 10 are bent, with the middle parts of the two swing arms 10 being far apart from each other and the two ends being close to each other. In this way, when the driving end 13 of the swing arm 10 is subjected to force and swings, the clamping end 12 can swing in the opposite direction.

[0067] The swing drive unit includes a drive cylinder 16 fixed on the support platform 9. A swing control component is connected to the cylinder rod of the drive cylinder 16, and the swing control component is located between two swing arms 10. In this embodiment, the swing control component is a wheel 17 rotatably connected to the cylinder rod of the drive cylinder 16. The wheels 17 are arranged in two symmetrical sets, and the two sets of wheels 17 abut against the two swing arms 10 respectively. This reduces the diameter of the wheels 17, making them easier to configure and install. In practical applications, the wheel 17 can also be designed as a single wheel, which abuts against both swing arms 10 simultaneously, thus reducing the number of wheels 17.

[0068] Combine Figure 2 and Figure 5As shown, the tying mechanism 7 also includes a nail holder 18 for storing the tying nails 8. The nail holder 18 is fixed on the support platform 9. The nail holder 18 has a horizontal part 19 and a vertical part 20 that are connected to each other and integrally formed. The horizontal part 19 and the vertical part 20 are smoothly transitioned. The support platform 9 is provided with a nail mounting position 21. The vertical part 20 is located directly above the nail mounting position 21. A push handle 22 is fixedly connected to the cylinder rod of the drive cylinder 16. The nail mounting position 21 is located between the notch 14 and the push handle 22 and is located on the movement path of the push handle 22. The push handle 22 is used to push the tying nails 8 from the nail mounting position 21 to the notch 14 to push the tying nails 8.

[0069] A pusher head 23 is slidably provided on the horizontal part 19 of the nail holder 18. The pusher head 23 is used to push the binding nail 8 along the nail holder 18. A compression spring is connected between the pusher head 23 and the nail holder 18. The pusher head 23 generates a continuous pushing force on the binding nail 8 through the compression spring, so that the binding nail 8 can be automatically pushed to the nailing position 21 one after another.

[0070] like Figure 2 As shown, the device also includes a lifting cylinder 24, the cylinder seat of the lifting cylinder 24 is rotatably connected to the fixed frame 2, and the cylinder rod is rotatably connected to a mounting plate 25. The mounting plate 25 is rotatably connected to the fixed frame 2, and a control cylinder 26 is fixedly mounted on the mounting plate 25. The cylinder rod of the control cylinder 26 is fixedly connected to the cylinder seat of the drive cylinder 16.

[0071] In this embodiment, the binding nails 8 are arc-shaped and arranged on the nail holder 18. When arranged, the binding nails 8 on the horizontal part 19 have their openings facing upwards, and the binding nails 8 on the vertical part 20 have their openings facing the notch 14. The pusher head 23 generates a continuous pushing force on the binding nails 8 through a compression spring, so that the binding nails 8 can be automatically pushed to the mounting position 21 one after another. Adjacent binding nails 8 are fixed with local adhesive, so that adjacent binding nails 8 have a certain fixing and binding effect, preventing the binding nails 8 from falling freely on the vertical section to the mounting position 21. At the same time, due to the local adhesive effect, the arrangement of binding nails 8 can change the arrangement direction at the turning point of the connection between the horizontal part 19 and the vertical part 20 without separating. After the binding nails 8 are installed, the binding nail 8 at the bottom of the vertical part 20 just detaches from the vertical part 20 and falls into the mounting position 21. However, at this time, the binding nail 8 is still not separated from the binding nail 8 above it due to the adhesive effect. That is, the distance between the mounting position 21 and the bottom of the vertical part 20 is just the thickness of one binding nail 8. This ensures that only one binding nail 8 falls into the mounting position 21 at a time.

[0072] When it is necessary to fill the packaging bag 60, the flipping cylinder 5 works and the flipping frame 3 flips and moves to the top of the fixed frame 2. At this time, the feeding pipe 4 is located directly above the packaging table 6 and the packaging bag 60. The packaging bag 60 is placed on the packaging table 6, and the feeding pipe 4 fills the packaging bag 60. After the filling is completed, the bag opening 61 of the packaging bag 60 is twisted into a strand or the bag opening 61 is squeezed and closed in the middle, and then the bag is tied and sealed.

[0073] During sealing, the lifting cylinder 24 operates and flips the sealing mechanism 7 from a vertical state to a horizontal state via the mounting plate 25. Then, the control cylinder 26 operates and pushes the drive cylinder 16 and the support platform 9 forward until the bag opening 61 of the packaging bag 60 enters the notch 14 from the front end of the notch 14. In actual application, a pair of guide nozzles 27 can be set at the front end of the support platform 9, with the notch 14 located between the two guide nozzles 27. The guide nozzles 27 can be used to guide the packaging bag 60 so that the bag opening 61 of the packaging bag 60 can enter the notch 14 completely and smoothly. After the drive cylinder 16 and the support platform 9 move to the predetermined position, the drive cylinder 16 operates. The cylinder rod of the drive cylinder 16 drives the wheel 17 and the push handle 22 to move linearly. The push handle 22 pushes the binding nail 8 on the nailing position 21 forward, so that the binding nail 8 separates from the binding nail 8 on the nail holder 18 and moves to the notch 14 for binding. After the binding nail 8 is moved to the notch 14, the cylinder rod of the drive cylinder 16 retracts, causing the push handle 22 and the wheel 17 to move backward. The wheel 17 pushes against the drive end 13 of the swing arm 10, causing the drive ends 13 of the two swing arms 10 to open, and the clamping ends 12 of the two swing arms 10 to swing in opposite directions and close, thereby squeezing the two ends of the binding nail 8 inward to close it, so that the binding nail 8 is tied to the bag opening 61, completing the tying process.

[0074] Then the cylinder rod of the drive cylinder 16 extends and resets again, the wheel 17 moves toward the nailing position 21, the drive end 13 of the swing arm 10 resets under the action of the tension spring, thereby causing the clamping ends 12 of the two swing arms 10 to move away from each other and reset. Then the control cylinder 26 controls the drive cylinder 16 and the support platform 9 to reset, so that the bag opening 61 of the packaged bag 60, carrying the tied ties 8, comes out from the front end of the notch 14, thus completing one sealing operation.

[0075] It's easy to think of, combining... Figure 5As shown, when the push handle 22 pushes the ties 8 on the mounting position 21 away and moves them to the notch 14, the upper end faces of the push handle 22 and the cylinder rod of the drive cylinder 16 are always abutting against the lower end of the nail holder 18. In this way, the push handle 22 and the cylinder rod of the drive cylinder 16 can isolate the lower end of the nail holder 18 from the mounting position 21. At this time, the next ties 8 will not fall into the mounting position 21 due to the obstruction of the push handle 22 and the cylinder rod of the drive cylinder 16. When one binding is completed, as the cylinder rod of the drive cylinder 16 and the push handle 22 move backward and move closer to the cylinder seat of the drive cylinder 16, when the push handle 22 moves between the mounting position 21 and the drive cylinder 16, there is no obstruction between the mounting position 21 and the lower end of the nail holder 18. The ties 8 located at the bottom of the nail holder 18 automatically fall into the mounting position 21 under the push of the push head 23, thus completing the automatic mounting of the ties 8.

[0076] Repeat the above process to proceed with the next bandaging operation.

[0077] When the sealing and packaging are completed and the packaging bag 60 needs to be removed, the flipping cylinder 5 works again and flips the flipping frame 3, opening up the space above the fixing frame 2 to facilitate the removal and placement of the packaging bag 60.

[0078] Example 2

[0079] The difference between this embodiment and Embodiment 1 lies in the structure of the swing control component, such as... Figure 6 As shown, the swing control component in this embodiment is a wedge block 28 that is fixedly connected to the cylinder rod of the drive cylinder 16. The diameter of one end of the wedge block 28 facing the notch 14 is larger than that of the other end. Both ends of the wedge block 28 are provided with wedge surfaces, and the wedge surfaces abut against the two swing arms 10.

[0080] The process of this embodiment is basically the same as that of embodiment 1, except that the swing control mechanism controls the swing of the swing arm 10. In this embodiment, when the drive cylinder 16 opens the drive ends 13 of the two swing arms 10 through the swing control mechanism, it uses the wedge block 28 to squeeze and push the swing arm 10 to swing. Compared with the wheel 17 pushing the swing arm 10, this embodiment uses the wedge block 28 to push the swing arm 10. Since the wedge surface of the swing control mechanism has a larger area to contact the swing arm 10, it is more conducive to controlling the swing of the swing arm 10.

[0081] Example 3

[0082] The difference between this embodiment and Embodiments 1 and 2 lies in the structure of the swing control component, such as... Figure 7 and Figure 8As shown, the swing control component in this embodiment includes a rack 29 fixedly connected to the cylinder rod of the drive cylinder 16. The rack 29 is arranged parallel to the axial direction of the cylinder rod of the drive cylinder 16. A gear 30 is meshed on the rack 29. A double-ended lead screw 31 is coaxially fixedly connected to the gear 30. The two ends of the double-ended lead screw 31 are rotatably connected to the support platform 9 through bearings, so that both the double-ended lead screw 31 and the gear 30 are rotatably engaged with the support platform 9. Both ends of the double-ended lead screw 31 are sleeved and threadedly connected to a sliding sleeve 32. The sliding sleeve 32 is slidably disposed on the support platform 9 along the axial direction of the double-ended lead screw 31. A pusher block is fixedly connected to the sliding sleeve 32, and two pushers 33 abut against the two swing arms 10 respectively. The sliding connection between the sliding sleeve 32 and the support platform 9 can be achieved by setting a sliding groove on the support platform 9, limiting and locking the sliding sleeve 32 in the sliding groove, so that the sliding sleeve 32 can only slide along the sliding groove and will not rotate with the double-ended lead screw 31.

[0083] In this embodiment, the process is basically the same as that of Embodiments 1 and 2, except that the swing control mechanism controls the swing arm 10 differently. In this embodiment, the swing control mechanism controls the swing arm 10 as follows: When the cylinder rod of the drive cylinder 16 shortens, the cylinder rod drives the rack 29 to move, and the rack 29 drives the gear 30 to rotate, which in turn causes the double-ended screw 31 to rotate. Since the threads at both ends of the double-ended screw 31 rotate in opposite directions, the two sliding sleeves 32 slide in opposite directions on the double-ended screw 31 and drive the push blocks 33 to push against the swing arm 10, causing the swing arm 10 to swing. Because the push blocks 33 do not move axially along the cylinder rod of the drive cylinder 16 during the process of pushing against the swing arm 10, the push blocks 33 only contact a small area of ​​the swing arm 10, thereby reducing the area that causes wear on the swing arm 10 and extending its service life.

[0084] Example 4

[0085] This embodiment is based on Embodiment 1, Embodiment 2, or Embodiment 3, such as... Figure 9 and Figure 10 As shown, the tilting frame 3 is also equipped with a swing cylinder 34 and a pair of swing grippers 35. The cylinder seat of the swing cylinder 34 is rotatably connected to the tilting frame 3 via a rotating shaft, and the cylinder rod is rotatably connected to the swing grippers 35 via a rotating shaft. In this way, while the swing cylinder 34 drives the swing grippers 35 to swing, the swing grippers 35 can rotate relative to the swing cylinder 34, so that the swing cylinder 34 adapts to the position of the swing grippers 35 without jamming the swing grippers 35. The two swing grippers 35 are used to squeeze and close the bag opening 61 of the packaging bag 60 in the left and right directions. The swing grippers 35 are both rotatably connected to the outer wall of the feed pipe 4, and the two swing grippers 35 can abut against each other when they are at the lowest point of the swing path.

[0086] Combine Figure 10 and 11As shown, one of the swing grippers 35 is provided with a front closing unit 36 ​​and the other swing gripper 35 is provided with a rear closing unit 37; both the front closing unit 36 ​​and the rear closing unit 37 include a translation drive, and the translation drive is fixedly connected to a translation gripper 39. The translation drive is used to drive the translation gripper 39 to translate along the length direction of the swing gripper 35.

[0087] The swing gripper 35 includes a base 40 and two parallel layers of clamping plates 41. The base 40 has vertically extending adjustment holes 42 on its side edge. The clamping plates 41 are detachably fixed to the adjustment holes 42 by bolts. There is a gap between the two layers of clamping plates 41, forming a two-way through sealing cavity 43.

[0088] The translation drive component in this embodiment includes a translation screw 38, a sliding sleeve, and a drive motor. The two ends of the translation screw 38 are rotatably connected to the swing gripper 35 via bearings. The drive motor is fixed to the swing gripper 35, and its drive shaft is connected to the translation screw 38 and used to drive its rotation. The sliding sleeve is fitted onto the translation screw 38 and threadedly engaged with it. The sliding sleeve is fixedly connected to the translation gripper 39 via bolts, and the sliding sleeve is laterally slidably connected to the swing gripper 35. This slidable connection can be achieved by: providing a groove on the swing gripper 35 and locking the sliding sleeve within the groove. This limits the sliding sleeve, ensuring that when the translation screw 38 rotates, the sliding sleeve can only slide laterally along the axial direction of the translation screw 38 on the swing gripper 35, and will not rotate with the translation screw 38. Furthermore, the translation gripper 39 in this embodiment is C-shaped. The translation gripper 39 and the translation drive are both located between the two clamping plates 41. The translation drive can drive the translation gripper 39 to enter and exit the sealing cavity 43. This allows the two translation grippers 39 to move as close as possible or even touch each other when they move together, so as to enhance the sealing effect on the opening 61 of the packaging bag 60.

[0089] In practical applications, when it is necessary to fill the packaging bag 60, the bag opening 61 is placed at the feeding pipe 4 for filling.

[0090] After the filling is completed, the bag opening 61 of the packaging bag 60 needs to be sealed. Before sealing, the bag opening 61 is closed by this device. During the closing process, the swing cylinder 34 drives the swing gripper 35 to swing. The two swing grippers 35 swing downward from the side of the feed pipe 4 and move closer together, thereby squeezing and closing the bag opening 61 of the packaging bag 60 from both sides. Then, the drive motor drives the translation and rotation, and the translation screw 38 pushes the sliding sleeve to move horizontally and causes the translation gripper 39 to move laterally. The two translation grippers 39 move towards each other and abut against each other, thereby squeezing and closing the bag opening 61 in both directions. At this time, the bag opening 61 is squeezed and closed from four directions, thus changing from an open state to a closed state, completing the closing operation of the bag opening 61. The two clamping plates 41 and the C-shaped translation gripper 39 together clamp and pull the upper and lower parts of the bag opening 61. The binding wire can enter the sealing cavity 43 from the front or rear end to bind the middle of the bag opening 61.

[0091] When it is necessary to adjust the distance between the two clamps 41, simply remove the clamps 41 from the adjustment hole 42 and re-fix the clamps 41 at different positions in the adjustment hole 42.

[0092] After the bag opening 61 is sealed, the swing gripper 35 and the translation gripper 39 are reset and the bag opening 61 of the packaging bag 60 is released, referring to the aforementioned embodiment.

[0093] Example 5

[0094] The only difference between this embodiment and embodiment 4 is that the structure of the translation drive is different. In this embodiment, the translation drive is a translation cylinder, which is fixed on the swing gripper 35. The cylinder rod of the translation cylinder is fixedly connected to the translation gripper 39.

[0095] In this embodiment, the only difference from the implementation process of embodiment 4 is the closing process of the bag opening 61 in the front and back directions. In this embodiment, when closing the bag opening 61 in the front and back directions, the translation cylinder works and drives the translation gripper 39 to move laterally. The two translation grippers 39 move closer together and abut against each other, thereby squeezing and closing the bag opening 61 in both front and back directions.

[0096] Example 6

[0097] This embodiment is based on the foregoing embodiments, such as... Figure 12 , Figure 13 and Figure 14As shown, the device also includes a receiving mechanism 44 on the feeding pipe 4. The receiving mechanism 44 includes two sets of symmetrically arranged arc-shaped hoops 45. The feeding pipe 4 is located between the two sets of arc-shaped hoops 45. The two sets of arc-shaped hoops 45 can be spliced ​​to form a ring that fits around the lower end of the feeding pipe 4. The arc-shaped hoops 45 match the shape and curvature of the outer wall of the feeding pipe 4. A mounting frame 46 is fixed on the outer wall of the feeding pipe 4. Both sets of arc-shaped hoops 45 are rotatably connected to clamping arms 47 through a rotating shaft. The end of the clamping arm 47 away from the arc-shaped hoops 45 is rotatably connected to the mounting frame 46 through a rotating shaft. In this embodiment, the clamping arm 47 is bent with a certain angle between its two ends. A telescopic cylinder 48 is provided between the two sets of clamping arms 47. The cylinder rod and cylinder seat of the telescopic cylinder 48 are rotatably connected to the two sets of clamping arms 47 respectively, and the two ends of the arc-shaped hoops 45 are symmetrically arranged.

[0098] Both ends of the arc-shaped hoop 45 are fixedly connected to abutment portions 49, and clamping arms 47 are connected to abutment portions 49; the abutment portions 49 at both ends of one set of arc-shaped hoop 45 abut against the abutment portions 49 at both ends of another set of arc-shaped hoop 45; an auxiliary connecting arm 50 is connected between the abutment portion 49 and the mounting frame 46, and the two ends of the auxiliary connecting arm 50 are rotatably connected to the abutment portion 49 and the mounting frame 46 respectively through a rotating shaft; a transmission rod 51 is provided between the two auxiliary connecting arms 50 connected at both ends of the same arc-shaped hoop 45, and the transmission rod 51 is rotatably connected to the two auxiliary connecting arms 50 respectively through a rotating shaft.

[0099] In this embodiment, before placing the packaging bag 60 on the packaging table 6 for filling, the flipping frame 3 flips over to be above the packaging bag 60, with the feeding pipe 4 facing the packaging bag 60 and positioned between two arc-shaped clamps 45. When it is necessary to receive material and fix the bag opening 61 of the packaging bag 60, the bag opening 61 is placed over the lower end of the feeding pipe 4. Then, the telescopic cylinder 48 is activated, and the telescopic cylinder 48 retracts, thereby driving the two clamping arms 47 to swing inward. The lower end of the clamping arms 47 drives the supporting part 49 and the arc-shaped clamps 45 to move inward. When the supporting parts 49 on the two arc-shaped clamps 45 abut against each other, the arc-shaped clamps 45 press against the outer wall of the feeding pipe 4, thereby pressing and fixing the bag opening 61 of the packaging bag 60 to the outer wall of the feeding pipe 4 to ensure the receiving effect of the powder. After the receiving and filling is completed, the bag opening 61 of the packaging bag 60 is closed and sealed according to the implementation process of the aforementioned embodiment.

[0100] After the bag is closed and sealed, when it is necessary to remove the bag opening 61 of the packaging bag 60 from the feed tube 4, the telescopic cylinder 48 works and the cylinder rod extends, thereby driving the lower ends of the two clamping arms 47 to swing outward, and the holding part 49 and the arc-shaped hoop 45 also move outward. The two arc-shaped hoop 45 move away from each other, thereby releasing the pressure on the packaging bag 60. At this time, the bag opening 61 of the packaging bag 60 can be removed from the feed tube 4.

[0101] During the swinging of the clamping arm 47, the auxiliary connecting arm 50 follows the swing and assists the swing arm 10 in swinging, making the movement of the arc-shaped hoop 45 more stable. The design of the transmission rod 51 makes the auxiliary connecting arms 50 connected to both ends of the arc-shaped hoop 45 move synchronously, thereby making the movement control of both ends of the arc-shaped hoop 45 more synchronized.

[0102] Example 7

[0103] This embodiment is based on the foregoing embodiments, such as... Figure 15 , Figure 16 and Figure 18 As shown, the device also includes a traction mechanism, which includes multiple traction hangers 52 fixed on the tilting frame 3. Each traction hanger 52 includes a base plate 53 fixed on the tilting frame 3. The base plate 53 is provided with a traction cylinder 54, a traction arm 55, and a locking plate 56. The locking plate 56 is fixed on the base plate 53. The cylinder seat of the traction cylinder 54 and the middle part of the traction arm 55 are rotatably mounted on the base plate 53 via a rotating shaft. One end of the traction arm 55 is rotatably connected to the cylinder shaft of the traction cylinder 54 via a rotating shaft. The end of the traction arm 55 connected to the traction cylinder 54 is provided with a clearance groove 57 for the cylinder shaft to make way. The clearance groove 57 is used to make way for the cylinder shaft of the traction cylinder 54 during movement, so as to prevent the cylinder shaft from being stuck on the traction arm 55. The other end of the traction cylinder 54 is fixedly connected to a hook 58. The free end of the hook 58 can abut against the locking plate 56, so that the locking plate 56 closes and locks the free end of the hook 58, preventing the object from slipping off the free end of the hook 58.

[0104] Meanwhile, in this embodiment, there are four traction hangers 52, which are evenly distributed around the outer periphery of the feed pipe 4.

[0105] In addition, if Figure 17 As shown, multiple clips 59 are provided on the outer wall of the feeding tube 4. The multiple clips 59 are evenly distributed on the outer wall of the feeding tube 4 to clamp and fix the bag opening 61 of the packaging bag 60 to the outer wall of the feeding tube 4.

[0106] In this embodiment, based on the implementation process of the aforementioned embodiments, when the opening 61 of the packaging bag 60 is placed at the feeding pipe 4, the opening 61 of the packaging bag 60 is clamped and fixed to the outer wall of the feeding pipe 4 by the clamp 59, thereby assisting in fixing the opening 61 of the packaging bag 60 and making it easier to install and fix the packaging bag 60. Then, the end of the packaging bag 60 is pulled and suspended on the hook 58, and the four hooks 58 respectively pull the four corners of the packaging bag 60, so that the packaging bag 60 is pulled and can be effectively opened. This makes it easier for powder to enter the packaging bag 60 when receiving materials. After the corner of the packaging bag 60 is hung on the hook 58, the traction cylinder 54 works and drives the traction arm 55 to swing. The traction arm 55 drives the hook 58 to move and makes the free end of the hook 58 abut against the locking plate 56. The locking plate 56 closes and locks the free end of the hook 58 to prevent the packaging bag 60 from slipping off the hook 58, thereby providing stable suspension and traction for the packaging bag 60.

[0107] After the filling, closing and sealing are completed, when it is necessary to remove the packaging bag 60 from the hook 58, the bag opening 61 of the packaging bag 60 is removed from the clamp 59. At the same time, the traction cylinder 54 works again and drives the traction arm 55 to swing in the opposite direction. The traction arm 55 drives the hook 58 to move away from the locking plate 56. At this time, the free end of the hook 58 is opened, and the packaging bag 60 can be removed from the hook 58.

[0108] In practical applications, to facilitate the hanging of the packaging bag 60 by the hook 58, such as Figure 19 As shown, a handle that can be hung on the hook 58 can be provided on the packaging bag 60, making the hanging operation of the packaging bag 60 more convenient.
