Description

Technical Field

[0001] This utility model relates to the field of metal ring packaging technology, specifically to a binding force adjustment structure for an automatic iron ring packing machine. Background Technology

[0002] In the field of industrial product packaging, the ring wrapping machine has become an important piece of equipment for packaging circular products due to its automated wrapping and efficient protection features. Its core application is concentrated in the tire manufacturing industry.

[0003] The tire is made of a composite structure of rubber and cord. If the binding force is too strong, it can easily cause the tire body to deform and the cord to break, directly damaging the product. The tire packaging does not need to strictly isolate the outside air. It is only necessary to form a basic protective layer by wrapping with a film to prevent dust from adhering. However, when ring wrapping machines were attempted to be applied to the packaging of metal rings (especially those made of non-rust-resistant alloy materials), the design flaws of existing equipment gradually became apparent. During the storage and transportation of non-rust-resistant alloy iron rings (such as ordinary carbon steel rings and cast iron rings), the core requirement for packaging is high-strength sealing. If humid air seeps in through packaging gaps, it will react with the surface of the iron ring, causing oxidation and corrosion. This not only affects the product's appearance but also weakens the structural strength of the iron ring, directly reducing the product's pass rate. However, the low binding force of existing equipment, designed for tire packaging, cannot meet the sealing requirements of metal rings. Tires are made of a composite structure of rubber and cord; excessive binding force can easily lead to tire deformation and cord breakage, directly damaging the product. Tire packaging does not require strict isolation from external air; a basic protective layer formed by wrapping with a thin film is sufficient to prevent dust adhesion.

[0004] When existing equipment is used for packaging metal rings, insufficient winding force results in poor adhesion between the packaging film and the surface of the iron ring, which easily forms tiny gaps through which humid air can continuously seep in. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: An automatic iron ring strapping machine with adjustable strapping force structure, comprising: Packaging material tray 1 is rotatably mounted on the C-ring of the vertical ring winding packaging machine. A rotating rod 2 is mounted on the C-ring. Packaging material tray 1 and rotating rod 2 are coaxially rotatably connected. The packaging material fixing structure 3 is set on the outer periphery of the packaging material tray 1. The cylindrical packaging material is fixed on the packaging material tray 1 by the packaging material fixing structure 3. The packaging material fixing structure 3 is used to prevent the packaging material from slipping on the packaging material tray 1.

[0019] Tension adjustment component 4 is located on the side of the rotating rod 2 away from the C-ring. Adjusting the tension using tension adjustment component 4 changes the binding force, making it suitable for metal ring packaging. The specific model of the vertical ring wrapping machine is not limited; any commonly used models by technicians in the field are applicable. Horizontal machines are not recommended, as they are difficult to drive large-mass iron rings.

[0020] Furthermore, the packaging material fixing structure 3 includes a top rod 5 and telescopic holes 6. Multiple sets of radial telescopic holes 6 are formed on the outer periphery of the packaging material tray 1. The top rod 5 is installed within each telescopic hole 6, and a top rod telescopic structure that drives the top rod 5 to telescopically extend and retract is installed inside the packaging material tray 1. When the top rod 5 extends from the telescopic hole 6, it abuts against the inner paper tube of the packaging material, preventing the packaging material from rotating relative to the packaging material tray 1.

[0021] Furthermore, the telescopic structure of the top rod includes a rotating block 7, multiple sets of trajectory grooves 9, and multiple sets of trajectory push rods 10. A rotating groove 8 is provided on the side of the packaging material tray 1 facing away from the C-ring. The rotating block 7 is rotatably engaged within the rotating groove 8. The trajectory grooves 9 are located on the rotating block 7, and the trajectory push rods 10 are slidably engaged within the trajectory grooves 9, with one end of the trajectory push rod 10 fixedly connected to the top rod 5. The trajectory grooves 9 are arc-shaped, with one end farther from the center of the packaging material tray 1 and the other end closer to the center. As the rotating block 7 rotates, the distance between the trajectory push rod 10 and the center of the packaging material tray 1 can be changed, thereby changing the distance between the top rod 5 and the center of the packaging material tray 1, i.e., extending or retracting.

[0022] Furthermore, multiple sets of push rod slide grooves 11 are provided at the bottom of the rotating groove 8, and the push rod slide grooves 11 are connected to the telescopic hole 6. The end of the track push rod 10 that is away from the track groove 9 is slidably engaged in the push rod slide groove 11.

[0023] Furthermore, the end of the track push rod 10 facing away from the top rod 5 is provided with an anti-detachment protrusion 12, the size of which is larger than that of the track groove 9. The anti-detachment protrusion 12 is used to prevent the track push rod 10 and the rotating block 7 from separating from the packaging material tray 1.

[0024] Furthermore, multiple sets of operating blocks 13 are provided on the outer side of the rotating block 7, and anti-slip textures 14 are provided on the operating blocks 13. The operating blocks 13 and the anti-slip textures 14 facilitate the rotation and adjustment of the rotating block 7, and facilitate the loading and unloading of the packaging belt.

[0025] Furthermore, the tension adjustment component 4 includes a screw hole 15, a screw 16, a mating disc 17, and a friction ring 18. The screw hole 15 is located inside the rotating rod 2, and the screw 16 is threadedly connected to the screw hole 15. The mating disc 17 is located at the opening of the screw hole 15 and is fixedly connected to the screw 16. The friction ring 18 is located between the mating disc 17 and the packaging material tray 1. One side of the friction ring 18 abuts against the mating disc 17, and the other side of the friction ring 18 abuts against the side wall of the packaging material tray 1. It is recommended that the friction ring 18 be made of elastic tear-resistant silicone rubber. There are multiple friction rings 18, and the height of different friction rings 18 is different. The tension can be adjusted by using the friction between different friction rings 18 and the packaging material tray 1. Changing different friction rings 18 changes the magnitude of the friction, thereby changing the tension. When it is tighter, the rotational resistance of the packaging material tray 1 is greater, resulting in excessive tensile force on the packaging material and a tighter packaging.

[0026] Furthermore, a safety pin 19 is also provided at the tension adjustment assembly 4. One end of the safety pin 19 passes through the screw 16 and is fixedly connected to the C-ring, while the other end of the safety pin 19 is provided with an anti-loosening end. The safety pin 19 is used to prevent the screw 16 from loosening after rotation, thereby improving safety performance.

[0027] Structural Description: Packaging material tray 1: Rotatably mounted on the C-ring of the vertical ring wrapping machine, and coaxially connected to the rotating rod 2, it serves as the mounting carrier for the cylindrical packaging material, providing support and a base for rotation of the packaging material; Rotating rod 2: It is set on the C-ring of the vertical ring wrapping machine. One end is coaxially connected to the packaging material tray 1, and the other end is equipped with a tension adjustment component 4, which serves to connect the tray and transmit rotational power, and bear the adjustment component. Packaging material fixing structure 3: Set on the outer periphery of the packaging material tray 1, including components such as top rod 5 and telescopic hole 6, used to fix the cylindrical packaging material on the tray 1 and prevent the packaging material from slipping relative to the tray 1; Tightness adjustment component 4: Located on the side of the rotating rod 2 away from the C-ring, including components such as screw hole 15 and screw 16.

Top rod 5: It is set in the telescopic hole 6 on the outer periphery of the packaging material tray 1 and is driven by the top rod telescopic structure. When it extends, it can abut against the inner paper tube of the packaging material to restrict the relative rotation between the packaging material and the tray 1. Telescopic hole 6: Multiple sets of radial holes are opened on the outer periphery of the packaging material tray 1 to accommodate the push rod 5 and are connected to the push rod slide groove 11 at the bottom of the rotating groove 8 to provide a channel for the telescopic movement of the push rod 5; Rotating block 7: Rotating block 8 is inserted into the rotating groove 8 on the side of the packaging material tray 1 away from the C-ring. An operating block 13 is provided on the outside and a track groove 9 is provided on the top. When rotating, the track push rod 10 can be moved through the track groove 9. Rotating groove 8: It is located on the side of the packaging material tray 1 away from the C-ring and is used to accommodate the rotating block 7. Multiple sets of push rod slide grooves 11 connected to the telescopic hole 6 are provided at the bottom to provide rotation space for the rotating block 7 and guide the trajectory push rod 10. Track groove 9: An arc-shaped groove set on the rotating block 7, with one end farther from the center of the packaging material tray 1 and the other end closer to it. It slides and engages with the track push rod 10, and the distance between the track push rod 10 and the center of the tray 1 is changed by the rotation of the rotating block 7. Track push rod 10: One end is fixedly connected to the push rod 5, and the other end is slidably engaged in the track groove 9 and the push rod slide groove 11. It can transmit the power of the rotating block 7 and drive the push rod 5 to extend and retract within the telescopic hole 6. Push rod groove 11: Multiple grooves are formed at the bottom of the rotating groove 8 and are connected to the telescopic hole 6. They are used to accommodate the end of the track push rod 10 that is away from the track groove 9 and guide the track push rod 10 to slide radially. Anti-detachment protrusion 12: It is set at the end of the track push rod 10 away from the top rod 5, and its size is larger than the track groove 9. It can prevent the track push rod 10 from detaching from the track groove 9 and avoid the track push rod 10 from separating from the rotating block 7 and the material tray 1. Operating block 13: Located on the outside of rotating block 7, with anti-slip texture 14, it facilitates manual rotation of rotating block 7 by the operator, providing an operating part for adjusting the top rod telescopic structure; Anti-slip texture 14: The textured structure on the operating block 13 can increase the friction between the hand and the operating block 13, making it easier for the operator to rotate the operating block 13 stably. Threaded hole 15: A threaded hole opened in the rotating rod 2, which is threadedly connected to the screw 16, providing a threaded mating channel for the installation and adjustment of the screw 16; Screw 16: It is threadedly connected to the screw hole 15 in the rotating rod 2, and one end is fixed to the mating disc 17. The squeezing force of the mating disc 17 on the friction ring 18 can be adjusted by rotating it. Matching disc 17: It is set at the opening of the screw hole 15 and is fixedly connected to the screw 16. One side abuts against the friction ring 18, which can transmit the pressure of the screw 16 to the friction ring 18. Friction ring 18: It is set between mating disc 17 and packaging material tray 1. It is recommended to use elastic tear-resistant silicone rubber, which is available in different height specifications. By changing the rotation resistance of tray 1 through friction with tray 1, the binding force can be adjusted. Safety pin 19: One end passes through the screw 16 and is fixedly connected to the C-ring, and the other end is provided with an anti-detachment end, which can lock the position of the screw 16 and prevent the screw 16 from loosening due to vibration during equipment operation.

[0028] Working principle: During packaging, the cylindrical packaging material is first installed on the packaging material tray 1 through the packaging material fixing structure 3. The operating block 13 (with anti-slip texture 14) on the outside of the rotating block 7 can be manually rotated, causing the rotating block 7 to rotate within the rotating groove 8 of the packaging material tray 1. The arc-shaped track groove 9 on the rotating block 7 moves in conjunction with this. Because the distances from the two ends of the track groove 9 to the center of the packaging material tray 1 are different, the track push rod 10, which is slidably engaged in the track groove 9, will move radially along the push rod slide groove 11 (connected to the telescopic hole 6), thereby driving the top rod 5 to extend and retract within the telescopic hole 6. When the top rod 5 extends out of the telescopic hole 6, its end abuts against the inner paper tube of the packaging material, using radial pressure to restrict the relative rotation of the packaging material and the packaging material tray 1, preventing slippage. The end of the track push rod 10 opposite to the top rod 5 is provided with an anti-detachment protrusion 12 (larger than the track groove 9), which can prevent the track push rod 10 from detaching from the rotating block 7 from the packaging material tray 1, ensuring the stability of the fixing structure.

[0029] After the packaging material is installed, the packaging material tray 1 is coaxially connected to the C-ring of the vertical ring winding packaging machine via the rotating rod 2. Driven by the C-ring, the entire tray rotates, providing power for the metal ring to wind the packaging material. The tension adjustment component 4 changes the binding force by adjusting the rotational resistance of the packaging material tray 1: the screw hole 15 on the side of the rotating rod 2 opposite to the C-ring is internally threaded to the screw rod 16. A friction ring 18 (preferably made of elastic tear-resistant silicone rubber) is clamped between the mating disc 17 at the end of the screw rod 16 and the packaging material tray 1. When the screw rod 16 is rotated, the mating disc 17 squeezes the friction ring 18, changing the contact pressure between the friction ring 18 and the side wall of the packaging material tray 1. Simultaneously, friction rings 18 of different heights can be replaced to change the friction force. The greater the friction force, the stronger the resistance when the packaging material tray 1 rotates, and the greater the tensile force on the packaging material, ultimately making the packaging material on the surface of the metal ring more tightly wound, meeting the requirements for rust prevention and sealing.

[0030] Furthermore, the safety pin 19 at the tension adjustment component 4 passes through the screw 16 and is fixed to the C-ring at one end, while the other end is equipped with an anti-detachment end, which can lock the position of the screw 16 to prevent it from loosening due to vibration during equipment operation and ensure stable binding force. The entire structure solves the problem of insufficient force in traditional ring winding machines by using the packing material fixing structure 3 to prevent material slippage and the tension adjustment component 4 to precisely adjust the resistance, thus achieving high-strength and adjustable packing of metal rings.
