Description

Technical Field

[0001] This utility model relates to the field of strapping machine technology, and in particular to a wire tube fixing structure for processing wire binding heads. Background Technology

[0002] In the existing technology, automatic bundling machines are widely used in the steel, metal products, and wire processing industries to automatically bundle and package coiled or bundled metal wires. The core working component is the bundling head, which guides the bundling wire around the wire bundle and completes the tightening, knotting, or fastening actions. To achieve this function, the traditional bundling head usually needs to perform two basic compound movements: one is a rotational movement around the wire bundle to complete the winding of the wire; the other is a radial pushing and pulling movement relative to the wire bundle to achieve actions such as tightening, knotting, or cutting after winding. In these movements, the wire guide tube used to guide and transport the bundling wire is a key path component. Currently, in traditional designs, the wire guide tube is usually rigidly connected and integrated into the main moving part of the wire binding head. This means that when the wire guide tube rotates at high speed and reciprocates with the wire binding head, the wire passing through it is forced to undergo complex compound motion. This design has several significant technical defects: unstable wire state and easy damage: During the rotation and pushing and pulling of the wire binding head, the violent movement of the wire guide tube will cause the wire inside to be forced to undergo unnecessary bending, twisting and friction; large and fluctuating wire feeding resistance: The dynamic movement of the wire guide tube makes the wire conveying path constantly changing, and the wire feeding resistance is unstable; complex structure and inconvenient maintenance: Since the wire guide tube moves with the moving parts, it is not convenient to carry out maintenance operations.

[0003] Chinese utility model patent application number 202022055410.X discloses a strapping tape cutting device for a strapping machine, including a housing. A support frame is fixedly connected to the upper center of the housing. A through slot is opened below the support frame and on the housing. A guide rail cavity is provided inside the support frame, and a narrow slit is opened on the cavity wall. A cylinder and a binding seat are respectively fixedly embedded on two opposite side walls of the support frame. A motor is also screwed to the upper side of the housing. The output shaft of the motor passes through the housing and is fixedly connected to a rotating rod. A drive gear is fixedly sleeved on the outer side of the rotating rod. However, in this type of strapping tape cutting device, the wire feeding tube is fixedly connected to the wire head, which leads to unstable wire condition, easy damage, excessive wire feeding resistance and fluctuations, complex structure, and inconvenience for later maintenance.

A wire-passing tube fixing structure for wire-binding head processing includes a wire-passing tube 1, which is mounted on a binding machine. It also includes an installation mechanism for forming a combined mounting structure, a push-pull mechanism for forming a reciprocating push-pull structure, and a rotating mechanism for forming a concentric rotating structure. The installation mechanism is mounted on the outer side of one end of the wire-passing tube 1, the push-pull mechanism is sleeved on the outer side of the wire-passing tube 1, and the rotating mechanism is mounted on the outer side of the push-pull mechanism corresponding to the wire-passing tube 1. A schematic diagram of the overall structure of this utility model is shown below. Figure 1 As shown.

[0019] The installation mechanism includes a wire tube support 2 and a limiting component. The wire tube support 2 is located on the outer side of one end of the wire tube 1 and is fixedly connected to the wire tube 1. The wire tube 1 is mounted on the strapping machine via the wire tube support 2. The limiting component is mounted on the outer side of the end of the wire tube 1 near the wire tube support 2. The installation mechanism, through the cooperation of the wire tube support 1 and the limiting component, forms a limiting installation structure to meet the installation requirements of the wire tube 1. Specifically, the wire tube support 2 is used to mount the wire tube 1 on the strapping machine, and the limiting component is used to limit the movement of the wire tube 1 and restrict the stroke of the push-pull mechanism. A cross-sectional view of the installation mechanism and the wire tube 1 in this utility model is shown below. Figure 2 As shown.

[0020] The limiting assembly includes a limiting cylinder 3 and a limiting core block 4. The limiting cylinder 3 is located outside the wire guide tube 1 and is sleeved with the wire guide tube 1. The limiting cylinder 3 is assembled and connected to the strapping machine. The limiting core block 4 is located inside the limiting cylinder 3 and is slidably connected with the limiting cylinder 3. The limiting core block 4 is sleeved on the outside of the wire guide tube 1. The limiting core block 4 consists of an integrally formed mounting core tube and a limiting plate. The two ends of the mounting core tube protrude from the two ends of the limiting cylinder 3. The limiting plate is located inside the limiting cylinder 3 and its side is connected to the limiting cylinder 3. There is a gap between the inner walls of the positioning cylinder 3. The axial section of the limiting core block 4 is set as a cross-shaped structure. The limiting component cooperates with the limiting cylinder 3 and the limiting core block 4 to limit the wire tube 1 and limit the stroke of the push-pull mechanism. The limiting cylinder 3 is fixedly set and pushes the push-pull rod 5 to move axially, and provides installation support for the limiting core block 4. The limiting core block 4 is used to connect with the push-pull mechanism to limit the stroke of the push-pull mechanism and limit the wire tube 1 under the action of the limiting cylinder 3.

[0021] The push-pull mechanism includes a push-pull rod 5, a hollow connector 6, and a cylinder connector 7. The push-pull rod 5 is located on the outer side of the middle of the thread guide tube 1 and is sleeved with the thread guide tube 1.

The cylinder connector 7 is located on the end of the hollow connector 6 away from the push-pull rod 5 and is sleeved with the hollow connector 6. The assembly and connection of the push-pull mechanism, through the cooperation of push-pull rod 5, hollow joint 6, and cylinder joint 7, constitutes a push-pull structure to meet the push-pull action requirements of the binding head. Push-pull rod 5 is used for axial reciprocating motion driven by limit cylinder 3. Hollow joint 6 is used to achieve the assembly connection between cylinder joint 7 and push-pull rod 5 through oilless bushing 8 and angular contact ball bearing 9.

The angular contact ball bearing 9 is assembled between the hollow joint 6 and the push-pull rod 5. The hollow joint 6 is rotatably connected to the push-pull rod 5 through the angular contact ball bearing 9. The oilless bushing 8 is used to reduce the friction between the hollow joint 6 and the threaded tube 1, thereby avoiding the movement of the hollow joint 6 from affecting the threaded tube 1.

There are two sets of deep groove ball bearings 12, which are symmetrically arranged at both ends of the rotating sleeve 11 and assembled with the push-pull rod 5. The rotating mechanism, through the cooperation of the fixed seat 10, the rotating sleeve 11, and the deep groove ball bearing 12, forms a rotating structure to meet the rotational action requirements of the binding head. The fixed seat 10 is used to rotate under the action of the motor on the binding machine, and drives the hollow connector 6 and the cylinder connector 7 to rotate. The rotating sleeve 11 is used to provide stable support for the fixed seat 10 and reduce the friction force on the fixed seat 10. The deep groove ball bearing 12 is used to realize the rotational assembly between the fixed seat 10 and the bearing seat 13 and to provide stable rotational support for the fixed seat 10.

[0024] It also includes a bearing housing 13, which is located outside the two sets of deep groove ball bearings 12 and is assembled and connected to the strapping machine. The fixed seat 10 is rotatably connected to the bearing housing 13 through the deep groove ball bearings 12. The two ends of the fixed seat 10 protrude from the two ends of the bearing housing 13, and the side of the fixed seat 10 near the cylinder connector 7 is provided with a clearance groove. The end of the fixed seat 10 away from the clearance groove is spaced from the limiting cylinder 3. The bearing housing 13 is used as a mounting structure on the strapping machine, thereby providing stable rotational support for the fixed seat 10 through the deep groove ball bearings 12. The schematic diagram of the bearing housing 13 and the fixed seat 10 of this utility model is shown below. Figure 4 As shown.

[0025] It also includes retaining rings 14 for bores. There are two sets of retaining rings 14. The two sets of retaining rings 14 are respectively disposed on the outer side of the two sets of deep groove ball bearings 12 and assembled and connected with the bearing housing 13. The two sets of retaining rings 14 are respectively located on the inner side of both ends of the bearing housing 13. The retaining rings 14 are used as mounting structures on the inner side of the ends of the bearing housing 13, thereby axially positioning and fixing the deep groove ball bearings 12 and preventing the bearings from coming out.

[0026] Working principle: During operation, the wire passes through the wire tube 1 and the fixed structure. The wire binding head rotates with the fixed seat 10, the hollow connector 6, and the cylinder connector 7. The push-pull rod 5 reciprocates axially under the drive of the limit cylinder 3, which in turn pushes the hollow connector 6 and the cylinder connector 7 to reciprocate. During the rotation and push-pull motion of the wire binding head, the wire tube 1 remains fixed under the action of the wire tube support 2, keeping it radially and axially stationary, thereby ensuring that the wire passing through the wire tube 1 is not affected by the movement of other parts.

[0027] The advantages of this utility model are its simple structure, the installation mechanism that provides installation support for the wire feeding tube while separating the wire feeding tube from the wire binding head, the push-pull mechanism and the rotation mechanism that work together to realize the rotation and push-pull action of the wire binding head and keep the wire feeding tube fixed during operation. This ensures that the wire passing through the wire feeding tube is not affected by the movement of other parts, avoids instability of the wire, reduces the possibility of wire damage, avoids excessive wire feeding resistance and ensures stable wire feeding resistance. All parts are detachable, which facilitates later maintenance.

[0028] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
