Description

Technical Field

[0001] This utility model relates to steel pipe packaging technology, specifically to a steel pipe film packaging and winding mechanism. Background Technology

[0002] In the downstream section of the steel pipe production plant, after the steel pipes are cut to the specified length, several pipes are bundled and wrapped as required. Usually, the outermost layer is wrapped repeatedly with plastic film to achieve the requirements of fixation and waterproofing. Currently, several steel pipes are suspended and wrapped manually, which is very inconvenient, inefficient, labor-intensive, and also poses certain safety hazards. Utility Model Content

[0003] In view of the above problems, this utility model proposes a steel pipe film packaging wrapping mechanism that can quickly complete the wrapping of the film.

[0004] The technical solution of this utility model:

[0005] A steel pipe film packaging and winding mechanism includes a steel frame and a winding device. The winding device includes a rotating fixed disk and a film support. The rotating fixed disk is mounted on the steel frame and is annular. The film support is mounted on the rotating fixed disk. A bundle of steel pipes is placed on the steel frame. The rotating fixed disk is sleeved on the bundle and moves along the direction of the bundle. A film is placed on the film support and moves along the direction of the bundle with the rotating fixed disk. During the movement, the film support rotates around the bundle, and the film rotates with the film support and wraps around the bundle.

[0006] To further refine the above technical solution, a cantilever is installed on the steel frame, the end of the cantilever extends above the tube bundle, and the rotating fixing disk is fixed to the end of the cantilever and located below the end of the cantilever; the cantilever moves along the direction of the tube bundle, and the rotating fixing disk moves together with the cantilever along the direction of the tube bundle.

[0007] Further refining the above technical solution, the cantilever root is connected to the steel frame via two sets of sliders / rails. The two sets of sliders / rails are positioned above and below the cantilever root and are staggered. One set of sliders / rails on the cantilever root is located at the far end, and the other set of sliders / rails below the cantilever root is located at the near end. The sliders are fixed to the cantilever root, and the rails are fixed to the steel frame, thus ensuring stable movement of the cantilever.

[0008] To further refine the above technical solution, a drive structure is installed on the steel frame, and the drive structure connects to the cantilever and drives the cantilever to move along the tube bundle direction.

[0009] Further refining the above technical solution, the drive structure consists of a motor connected to a lead screw and a lead screw nut.

[0010] Further refining the above technical solution, the rotating fixed disk is equipped with a gear and an external gear ring. The gear meshes with the external gear ring, and the external gear ring is coaxial with the rotating fixed disk. The gear is a driving gear, which is driven to rotate by a motor. The film support is fixed on the external gear ring and its teeth are offset from those of the external gear ring. When the external gear ring rotates, the film support rotates together with the external gear ring and rotates around the tube bundle.

[0011] Further refining the above technical solution, the packaging wrapping mechanism includes a piano-key type movable support, which consists of at least three tube bundle supports. These supports are arranged side-by-side and collectively support the tube bundles, which can move vertically. This supports the tube bundles while avoiding interference with the wrapping device (when the rotating fixed disc passes by the tube bundle support, the support moves downwards to avoid it). The reason for having at least three tube bundle supports is to ensure that the tube bundles still have stable support even after one support moves downwards.

[0012] Further refining the above technical solution, a lifting structure includes a lifting boom, a lifting arm, and a lifting hydraulic cylinder. The lifting boom is located at the top, with one end hinged to the steel frame and the other end hinged to the support. The lifting arm is located at the bottom, with one end hinged to the steel frame and the other end hinged to the support. The lifting hydraulic cylinder is mounted on the steel frame and connected to the lifting boom or the lifting arm. The lifting hydraulic cylinder drives the lifting boom and the lifting arm to swing up and down synchronously, and the support moves up or down.

[0013] Further refining the above technical solution, the lifting boom and the lifting auxiliary boom are both composed of parallel double rods connected together. The parallel double rods are mounted on both sides of the diagonal brace of the steel frame with a clearance fit, thereby improving the stability of the lifting boom and the lifting auxiliary boom swinging up and down.

[0014] Further refining the above technical solution, the support surface of the tube bundle support has a groove for accommodating the tube bundle placed therein.

[0015] The advantages of this utility model are that it has a reasonable design and simple structure. The annular rotating fixing disk, combined with the film support design, allows the film to move along the direction of the tube bundle and rotate around the tube bundle, so as to complete the wrapping of the film quickly in one go.

Detailed Implementation

[0020] like Figure 1-3 As shown, the steel pipe film wrapping mechanism includes a steel frame 1, a wrapping device 2, a key-type movable support 3, a tube bundle 4 composed of several steel pipes, and a film 5.

[0021] The winding device 2 includes a rotating fixing disk 2-1 and a film support 2-2. The root of the cantilever 2-3 is connected to the steel frame 1 via two sets of sliders / rails. The two sets of sliders / rails are positioned above and below the root of the cantilever 2-3 and are staggered. One set of sliders / rails on the root of the cantilever 2-3 is located at the far end, and the other set of sliders / rails below the root of the cantilever 2-3 is located at the near end. The sliders are fixed to the root of the cantilever 2-3, and the rails are fixed to the steel frame 1. The end of the cantilever 2-3 extends above the tube bundle 4. The rotating fixing disk 2-1 is fixed to the cantilever 2-3. At the end of arm 2-3, below the end of cantilever 2-3, drive structure 2-4 is mounted on steel frame 1 and connected to cantilever 2-3. Rotating fixed disk 2-1 is equipped with gear 2-5 and external gear ring 2-6. Gear 2-5 meshes with external gear ring 2-6. External gear ring 2-6 is coaxial with rotating fixed disk 2-1. Gear 2-5 is the driving gear. Membrane bracket 2-2 is fixed on external gear ring 2-6 and its teeth are offset from those of external gear ring 2-6. Drive structure 2-4 is composed of motor, lead screw, and lead screw nut.

[0022] The key-type movable support 3 consists of five tube bundle supports 3-1 arranged side by side. The lifting structure 3-2 includes a lifting boom 3-2-1, a lifting auxiliary boom 3-2-2, and a lifting hydraulic cylinder 3-3-3. The lifting boom 3-2-1 is located at the top, with one end hinged to the steel frame 1 and the other end hinged to the tube bundle support 3-1. The lifting auxiliary boom 3-2-2 is located at the bottom, with one end hinged to the steel frame 1 and the other end hinged to the tube bundle support 3-1. The lifting hydraulic cylinder 3-2-3 is installed on the steel frame 1 and connected to the lifting boom 3-2-1. The lifting boom 3-2-1 and the lifting auxiliary boom 3-2-2 are both composed of parallel double rods connected together. The parallel double rods are mounted on both sides of the diagonal brace of the steel frame 1 with a clearance fit. The support surface of the tube bundle support 3-1 has a groove to accommodate the tube bundle 4 placed therein.

[0023] When the above-mentioned packaging wrapping mechanism is used, the tube bundle 4 (suspended) is placed on each tube bundle support 3-1 and is supported by each tube bundle support 3-1. The rotating fixed disk 2-1 is sleeved on the tube bundle 4. The film 5 is placed on the film support 2-2. The drive structure 2-4 drives the cantilever 2-3 to move along the tube bundle direction. The rotating fixed disk 2-1 moves along the tube bundle direction together with the cantilever 2-3. The film 5 and the film support 2-2 move along the tube bundle direction together with the rotating fixed disk 2-1. During the movement, the gear 2-5 is driven to rotate by the motor. The external gear 2-6 rotates. The film 5 and the film support 2-2 rotate together with the external gear 2-6 and rotate around the tube bundle 5. The film 6 is wrapped around the tube bundle 4.

[0024] When the rotating fixed plate 2-1 moves the tube bundle support 3-1 to a different position, the lifting hydraulic cylinder 3-2-3 drives the lifting boom 3-2-1 and the lifting auxiliary boom 3-2-2 to swing downwards simultaneously, and the tube bundle support 3-3 moves downwards to avoid the rotating fixed plate 2-1.
