DETAILED DESCRIPTION

[0025] A specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation. Example

[0026] like Figure 1-4 As shown, a steel coil coreless cutting machine includes a bearing frame 1 and at least two correspondingly arranged roller assemblies 2. In this embodiment, the number of roller assemblies 2 is two and they are symmetrically arranged. The roller assembly 2 includes a rotating support frame 21 located on both sides and a plurality of rotating rollers 22 rotatably connected to the rotating support frame 21. The rotating rollers 22 on both sides form a "V"-shaped supporting space. The steel coil 9 is placed in the "V"-shaped supporting space and supported by the plurality of rotating rollers 22. Under its own gravity, friction is generated with the plurality of rotating rollers 22, thereby realizing rotation. Moreover, since it is placed in the "V"-shaped supporting space, its rotation process is very stable.

[0027] The rotating support frame 21 is rotatably connected to the roller base 25 through a rotating pin, so that it can swing within a certain range, thereby adapting to the continuous change of the diameter of the steel coil 9. The rotating support frame 21 is preferably an "L"-shaped support frame, and the rotating rollers 22 are evenly distributed on the "L"-shaped support frame. The "L"-shaped support frame can make the rotating rollers 22 on both sides convenient to form a "V"-shaped supporting space. In this embodiment, the number of rotating rollers 22 on each side is two, and the rotating rollers 22 on both sides are synchronously driven to rotate by a roller driving mechanism.

[0028] Specifically, the roller driving mechanism includes a driving element 51, a second chain transmission system 52 and a main sprocket 53 located on the rotating support frame 21. The driving element 51 drives the main sprocket 53 to rotate synchronously through the second chain transmission system 52. The main sprocket 53 is provided with a main transmission gear 54. The rotating roller 22 is provided with a passive gear 55 that cooperates with the main sprocket 53. The driving element 51 includes a motor and a reducer. Example

[0029] On the basis of Example 1, Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, a traction mechanism 3 is also provided at one end of the supporting frame 1 (i.e., the discharging end), and the traction mechanism 3 includes a plurality of upper rollers 31, a plurality of lower rollers 32 arranged in parallel, and roller brackets 33 located on both sides, and both ends of the upper rollers 31 and the lower rollers 32 are rotatably connected to the roller brackets 33, wherein a plurality of lower rollers 32 are synchronously driven to rotate through a first transmission system 41, and the first transmission system 41 is a first chain transmission system, and the driving element 51 simultaneously drives a plurality of lower rollers 32 to rotate synchronously through the first chain transmission system, and the material sheet passes between the upper rollers 31 and the lower rollers 32, and the material sheet is pulled forward by friction.

[0030] Both ends of the upper roller 31 are rotatably connected to a movable slider 34, and the movable slider 34 is slidably connected to the roller bracket 33. A compression spring 35 is provided above the movable slider 34. This structure can stabilize the friction force (i.e., traction force) to ensure stable conveying of the sheet, and can also adapt to sheets of different thicknesses.

[0031] Combination Figure 5 As shown, a sliding baffle 23 and a fixed baffle 24 are respectively provided at both ends of the rotating roller 22. The fixed baffle 24 can slide back and forth along the length direction of the rotating roller 22 to change the distance between it and the sliding baffle 23. The baffles at both ends can fix the material roll in a limited position to prevent it from unnecessary displacement during the movement. Specifically, the sliding baffle 23 includes a first wedge-shaped disk 231 and a second wedge-shaped disk 232 matched with the first wedge-shaped disk 231. The first wedge-shaped disk 231 and the second wedge-shaped disk 232 are inserted into the rotating roller 22. After the two are matched and connected, they can slide synchronously along the rotating roller 22 and be locked and fixed to the rotating roller 22 by the ejection bolts 233. The sliding baffle 23 can be fixed at any position of the rotating roller 22 through the wedge structure to adapt to the width of the steel coil 9.

[0032] Special combination Figure 8 As shown, since the rotating roller 22 is relatively long and the steel coil 9 is relatively heavy, in order to protect the rotating roller 22, enable it to operate stably and extend its service life, the roller assembly 2 is auxiliary rolling supported by an auxiliary support roller assembly 6, and the auxiliary support roller assembly 6 includes a plurality of rollers 61 corresponding to the rotating roller 22, a roller frame 62 and a roller base 63, and the plurality of rollers 61 are rotatably connected to the roller frame 62, and the roller frame 62 is rotatably connected to the roller base 63 via a rotating pin.

[0033] In order to prevent the steel coil 9 from falling and causing unnecessary accidents, a steel coil protection bracket 7 is provided on the rear side of the supporting frame 1.

[0034] In order to facilitate leveling and adjustment, a plurality of shock-absorbing adjustable feet 8 are distributed below the supporting frame 1 .

[0035] The working principle of the present invention is as follows: the steel coil 9 is placed in a "V"-shaped supporting space and supported by a plurality of rotating rollers 22. The steel coil 9 generates friction with the plurality of rotating rollers 22 under its own gravity. Under the joint action of the plurality of rotating rollers 22, the steel coil 9 is rotated to cut the material, and the material is transported outward by the traction of the traction mechanism 3. With the continuous outward transportation, since the roller assembly 2 is rotatably connected, it can swing within a certain range. Therefore, as the diameter of the steel coil 9 gradually decreases, under the action of the gravity of the steel coil 9, the roller assembly 2 adaptively changes its position, so that the rotating rollers 22 always support the steel coil 9 in rotation and are always in a stable state.

[0036] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
