Description

Technical Field

[0001] This invention relates to the field of metallurgical equipment technology, specifically to a device for preventing jamming of the core shaft in ball winding and a ball winding machine. Background Technology

[0002] The purpose of the ball-rolling machine is to process the waste edges after the disc shearing. The disc shear is installed after the inspection looper on the continuous unloading line. It is mainly used to cut the edges of steel strips that are not in accordance with the user's specified dimensions, achieving the requirements for trimmed edges, width, and cut quality. After that, it is cut into single sheets by a cross-cutting process for supply to users, or rolled into coils by a coiling machine to meet the needs of different users. After the steel strip edges are cut by the disc shear, the excess waste edges (generally less than 25mm wide) are rolled into balls (maximum diameter 1m) by the ball-rolling machine for centralized processing and recycling.

[0003] The ball-winding machine mainly consists of several parts: shears, mandrel, disk, pressure roller, storage flap, and gate. After the steel strip is sheared, the excess waste edge is rotated by a motor, causing the waste edge to wind onto the mandrel. The pressure roller then crushes the waste edge to make the ball wind tighter. Both ends are sealed by the disk. When the diameter of the ball reaches 800-900mm, the shears cut off the waste edge, the mandrel moves outward, and the storage flap pours the ball out. Currently, in use, it is frequently encountered that the waste edge gets stuck at the connection point of the mandrel rods at both ends and cannot be pulled out, causing the waste edge to be wound into the ball and preventing it from being poured out, thus affecting the disc shearing process.

[0004] To address the above-mentioned technical problems, this invention proposes a device for preventing jamming of the ball winding core shaft and a ball winding machine. Summary of the Invention

[0005] The purpose of this invention is to provide a device for preventing jamming of the waste edge ball core shaft, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A device for preventing jamming of a waste edge ball spindle includes: a first spindle and a second spindle, the first spindle and the second spindle being symmetrically arranged; the first spindle includes a first segment and a second segment, the first segment being cylindrical and the second segment being frustoconical, the larger end of the second segment being located close to the first segment; the second spindle includes a third segment and a fourth segment, the third segment being cylindrical and the fourth segment being frustoconical, the larger end of the fourth segment being located close to the third segment, the smaller end of the second segment being connected to the smaller end of the fourth segment; a first disk and a second disk are respectively arranged on the upper and lower sides of the first segment; a third disk and a fourth disk are respectively arranged on the upper and lower sides of the third segment; there is a gap between the first disk and the first segment, a gap between the second disk and the first segment, a gap between the third disk and the third segment, and a gap between the fourth disk and the third segment.

[0007] As a further aspect of the present invention: the first segment and the second segment are an integral structure, and the third segment and the fourth segment are also an integral structure.

[0008] As a further embodiment of the present invention: the diameter of the first segment is greater than the diameter of the large end of the second segment, and the diameter of the third segment is greater than the diameter of the large end of the fourth segment.

[0009] As a further aspect of the present invention: the gap between the first disk and the second segment is 5mm, and the gap between the second disk and the second segment is 5mm.

[0010] As a further embodiment of the present invention: the gap between the third disk and the fourth segment is 5mm, and the gap between the fourth disk and the fourth segment is 5mm.

[0014] As a further embodiment of the present invention: the first disk and the second disk are symmetrically arranged on both sides of the second segment; the third disk and the fourth disk are symmetrically arranged on both sides of the fourth segment.

[0015] To achieve the above objectives, the present invention provides another technical solution as follows: A ball winding machine includes: scissors, a disk, a pressure roller, a storage flap, a gate, and a device to prevent the ball winding spindle from jamming due to waste edges.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the first mandrel and the second mandrel are changed from the cylinders of the prior art to the frustum shape, so that when the mandrel rotates, the rotational speed at the connection position between the first mandrel and the second mandrel is less than that at the second and fourth sections, reducing the movement of the waste edge to both ends and getting stuck in the disk gap. In addition, when the mandrel moves to both sides, the inner diameter of the waste ball increases from the middle to both sides, making it easier to pull out the first mandrel and the second mandrel.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Please see Figure 1 The present invention provides a structural diagram of a device for preventing jamming of waste edge rolled ball mandrels, comprising: a first mandrel 1 and a second mandrel 2, the first mandrel 1 and the second mandrel 2 being symmetrically arranged; the first mandrel 1 comprising a first segment 11 and a second segment 12, the first segment 11 being cylindrical and the second segment 12 being frustoconical, the larger end of the second segment 12 being disposed close to the first segment 11; the second mandrel 2 comprising a third segment 21 and a fourth segment 22, the third segment 21 being cylindrical and the fourth segment 22 being frustoconical, the larger end of the fourth segment 22 being disposed close to the third segment 21, the smaller end of the second segment 12 being connected to the smaller end of the fourth segment 22; a first disk 3 and a second disk 4 are respectively disposed on the upper and lower sides of the first segment 11; a third disk 5 and a fourth disk 6 are respectively disposed on the upper and lower sides of the third segment 21; there is a gap between the first disk 3 and the first segment 11, a gap between the second disk 4 and the first segment 11, a gap between the third disk 5 and the third segment 21, and a gap between the fourth disk 6 and the third segment 21.

[0021] The present invention changes the first mandrel 1 and the second mandrel 2 from the cylindrical shape of the prior art to a frustum shape, so that when the mandrel rotates, the rotational speed at the connection position between the first mandrel 1 and the second mandrel 2 is less than that at the second segment 12 and the fourth segment 22, reducing the movement of the waste edge to both ends and getting stuck in the disk gap. In addition, when the mandrel moves to both sides, the inner diameter of the waste ball increases from the middle to both sides, making it easier to pull out the first mandrel 1 and the second mandrel 2.

[0022] like Figure 1As shown, in some embodiments, the first segment 11 and the second segment 12 are integrally formed, and the third segment 21 and the fourth segment 22 are also integrally formed. The diameter of the first segment 11 is larger than the diameter of the larger end of the second segment 12, and the diameter of the third segment 21 is larger than the diameter of the larger end of the fourth segment 22. Therefore, a step 20 is formed between the first segment 11 and the second segment 12.

[0023] like Figure 1 As shown, in some embodiments, the gap between the first disk 3 and the second segment 12 is 5mm, the gap between the second disk 4 and the second segment 12 is 5mm, the gap between the third disk 5 and the fourth segment 22 is 5mm, and the gap between the fourth disk 6 and the fourth segment 22 is 5mm. Exemplarily, the first disk 3 may be located above the second segment 12, and the second disk 4 may be located below the second segment 12. The third disk 5 may be located above the fourth segment 22, and the fourth disk 6 may be located below the fourth segment 22. This invention reduces the disk gap to 5mm by shaping the spindle in a stepped manner at the disk location, which can block some of the waste edges within the disk, preventing the waste edges from getting stuck in or outside the gap.

[0024] The taper of the second segment 12 and the fourth segment 22 is 5°-10°.

[0025] In some embodiments, the first disk 3 and the second disk 4 are symmetrically arranged on both sides of the second segment 12. The third disk 5 and the fourth disk 6 are symmetrically arranged on both sides of the fourth segment 22.

[0026] Example 2 The present invention also provides a ball winding machine, comprising: scissors, a disk, a pressure roller, a storage flap, a gate, and a device for preventing waste edge ball winding spindle jamming; the device for preventing waste edge ball winding spindle jamming. The device for preventing jamming of the waste edge rolled ball mandrel includes: a first mandrel 1 and a second mandrel 2, the first mandrel 1 and the second mandrel 2 being symmetrically arranged; the first mandrel 1 includes a first segment 11 and a second segment 12, the first segment 11 being cylindrical and the second segment 12 being frustoconical, the larger end of the second segment 12 being disposed close to the first segment 11; the second mandrel 2 includes a third segment 21 and a fourth segment 22, the third segment 21 being cylindrical and the fourth segment 22 being frustoconical, the larger end of the fourth segment 22 being disposed close to the third segment 21, the smaller end of the second segment 12 being connected to the smaller end of the fourth segment 22; a first disk 3 and a second disk 4 are respectively disposed on the upper and lower sides of the first segment 11; a third disk 5 and a fourth disk 6 are respectively disposed on the upper and lower sides of the third segment 21; there is a gap between the first disk 3 and the first segment 11, a gap between the second disk 4 and the first segment 11, a gap between the third disk 5 and the third segment 21, and a gap between the fourth disk 6 and the third segment 21.

[0027] The present invention changes the first mandrel 1 and the second mandrel 2 from the cylindrical shape of the prior art to a frustum shape, so that when the mandrel rotates, the rotational speed at the connection position between the first mandrel 1 and the second mandrel 2 is less than that at the second segment 12 and the fourth segment 22, reducing the movement of the waste edge to both ends and getting stuck in the disk gap. In addition, when the mandrel moves to both sides, the inner diameter of the waste ball increases from the middle to both sides, making it easier to pull out the first mandrel 1 and the second mandrel 2.

[0028] In some embodiments, the first segment 11 and the second segment 12 are integrally formed, as are the third segment 21 and the fourth segment 22. The diameter of the first segment 11 is larger than the diameter of the larger end of the second segment 12, and the diameter of the third segment 21 is larger than the diameter of the larger end of the fourth segment 22. Therefore, a step 20 is formed between the first segment 11 and the second segment 12.

[0029] In some embodiments, the gap between the first disk 3 and the second segment 12 is 5mm, the gap between the second disk 4 and the second segment 12 is 5mm, the gap between the third disk 5 and the fourth segment 22 is 5mm, and the gap between the fourth disk 6 and the fourth segment 22 is 5mm. For example, the first disk 3 may be located above the second segment 12, and the second disk 4 may be located below the second segment 12. The third disk 5 may be located above the fourth segment 22, and the fourth disk 6 may be located below the fourth segment 22. This invention reduces the disk gap to 5mm and shapes the spindle in a stepped shape at the disk location, which can block some of the waste edges inside the disk, preventing the waste edges from getting stuck in or outside the gap.

[0030] The taper of the second segment 12 and the fourth segment 22 is 5°-10°.

[0031] In some embodiments, the first disk 3 and the second disk 4 are symmetrically arranged on both sides of the second segment 12. The third disk 5 and the fourth disk 6 are symmetrically arranged on both sides of the fourth segment 22.
