[0022] Moreover, although the present invention is described with reference to specific embodiments, it should be understood that these embodiments are merely examples of the principles and applications of the present invention. It should therefore be understood that many modifications may be made to the exemplary embodiments, and other arrangements may be designed without departing from the spirit and scope of the present invention as defined by the appended claims. It should be understood that different dependent claims and features herein may be combined in a manner not described in the original claims. It may also be understood that the features described in conjunction with the individual embodiments may be used in other embodiments.

[0023] To solve the above problems, Figure 1 As shown, the utility model provides a steel strip roll layer opening device, including a beam mechanism 1 and a pin mechanism 2, the beam mechanism 1 is used to pass through the roll core of the steel strip roll, and the two pin mechanisms 2 are respectively connected to the two ends of the beam mechanism 1, and the pin mechanism 2 is used to extend toward the steel strip roll and be inserted between two adjacent layers of the steel strip roll.

[0024] In this embodiment, a crossbeam mechanism 1 is arranged to pass through the winding core, the crossbeam mechanism 1 extends along the axial direction of the steel strip coil, and ejector mechanisms 2 are arranged at both ends of the crossbeam mechanism 1. The two ejector mechanisms 2 are respectively located at the two ends of the steel strip coil along its axial direction and are symmetrically arranged. The ejector mechanism 2 can be extended so that the end of the ejector mechanism 2 facing the steel strip coil can move toward the steel strip coil, and the ejector mechanism can also be shortened so that the end of the ejector mechanism 2 facing the steel strip coil can move away from the steel strip coil. When sampling is required, the ejector mechanism 2 is extended toward the steel strip coil until the ejector mechanism 2 pushes into two adjacent coil layers of the steel strip coil to increase the distance between the two coil layers. The two ejector mechanisms 2 work at the same time to increase the distance between the two coil layers, so that the cutting tool can extend from the space widened by the ejector mechanism 2 into between the two coil layers to sample the steel strip coil. This operation process replaces manual operation, has low danger, high sampling efficiency, and is convenient for sampling operations on the steel strip coil.

[0025] Specifically, the two ejector mechanisms 2 work simultaneously to increase the distance between the two coil layers, provide operating space for flame cutting, and avoid damage to adjacent steel coils by flame and slag. After sampling, the two ejector mechanisms 2 retract in the direction away from the steel strip coil to complete the sampling operation.

[0026] Alternatively, if Figure 1 As shown, the ejector mechanism 2 includes an ejector 21 and a driving member 22 . The two driving members 22 are respectively connected to the two sides of the beam mechanism 1 . The driving member 22 is drivingly connected to the ejector 21 .

[0027] In this embodiment, the ejector mechanism 2 is divided into an ejector 21 and a driving member 22, the driving member 22 is connected to the end of the beam mechanism 1, and the driving member 22 is connected to the ejector 21 on the side facing the steel strip roll. The driving member 22 can drive the ejector 21 to move toward the steel strip roll or away from the steel strip roll, thereby realizing the extension and retraction of the ejector mechanism 2.

[0028] Optionally, the driving member 22 is a pneumatic cylinder, an electric cylinder or a hydraulic cylinder.

[0029] In this embodiment, the driving member 22 is set as a cylinder, an electric cylinder or a hydraulic cylinder, the fixed end of which is connected to the end of the beam mechanism 1, and the telescopic end of which is connected to the ejector pin 21. When working, the driving member 22 drives the ejector pin 21 to move toward or away from the steel strip roll, thereby realizing the telescopic movement of the ejector pin mechanism 2.

[0030] Specifically, the driving member 22 may also be driven by a motor gear rack. The structure of the driving member 22 only needs to drive the ejector pin 21 to move toward or away from the steel strip coil, and no specific limitation is made here.

[0031] Alternatively, if Figure 1 As shown, one end of the ejector pin 21 facing the steel strip coil is a sharp corner.

[0032] In this embodiment, by setting one end of the ejector pin 21 facing the steel strip coil as a sharp corner, the sharp corner is convenient for insertion between two coil layers that are tightly pressed together, and the edge of the sharp corner also provides a guide for the opposite movement of the two coil layers, so as to facilitate widening the width between the two coil layers. When the sampling is completed and the ejector pin 21 retracts away from the steel strip coil, the edge of the sharp corner is in oblique contact with the coil layer, so as to facilitate the ejector pin 21 to withdraw from the steel strip coil.

[0033] Optionally, the ejector pin 21 is made of steel.

[0034] In this embodiment, the ejector pin 21 is made of steel material, which has high strength and is wear-resistant, is easy to insert into the steel strip coil, can be used multiple times, is not easily damaged, and has a longer service life.

[0035] Specifically, the material of the ejector pin 21 is not specifically limited as long as it is a material with high strength and high wear resistance.

[0036] Alternatively, if Figure 1 As shown, the crossbeam mechanism 1 includes a first beam 11 and a second beam 12 , and the first beam 11 and the second beam 12 are slidably connected along the length direction of the crossbeam mechanism 1 .

[0037] In this embodiment, a first beam 11 and a second beam 12 are provided, both of which extend along the axial direction of the steel strip roll, and the first beam 11 and the second beam 12 are slidably connected at opposite ends to change the length of the crossbeam mechanism 1. Two ejector mechanisms 2 are respectively connected to the opposite ends of the first beam 11 and the second beam 12, and the first beam 11 and the second beam 12 are slidably connected, so that the length of the crossbeam mechanism 1 can be changed to adapt to steel strip rolls of different widths.

[0038] Alternatively, if Figure 1 As shown, the crossbeam mechanism 1 also includes a pin shaft 13, the second beam 12 is a hollow structure with one end open, the first beam 11 is partially penetrated by the second beam 12, and a plurality of corresponding pin holes are opened on the first beam 11 and the second beam 12, and the pin shaft 13 is penetrated by any two opposite pin holes on the first beam 11 and the second beam 12.

[0039] In this embodiment, by setting the second beam 12 as a hollow structure that is open at one end toward the first beam 11, the first beam 11 can be inserted into the open end of the second beam 12 and slide relative to the second beam 12 to achieve a change in the length of the beam mechanism 1. The first beam 11 and the second beam 12 are both provided with a plurality of pin holes on their overlapping portions. Any pin hole on the first beam 11 can overlap and penetrate with any pin hole on the second beam 12, respectively. A pin shaft 13 is provided to pass through the overlapping pin holes of the first beam 11 and the second beam 12 to fix the relative positions of the first beam 11 and the second beam 12 so that the overall length of the beam mechanism 1 is fixed. When it is necessary to change the length of the beam mechanism 1, the pin shaft 13 is pulled out, the first beam 11 is pulled out or inserted a certain distance relative to the second beam 12, the corresponding pin holes of the first beam 11 and the second beam 12 are changed, and the pin shaft 13 is inserted again to change the overall length of the beam mechanism 1.

[0040] Specifically, there can be two pin shafts 13, and the two pin shafts 13 are inserted into different pin holes at the same time to improve the stability of the connection between the first beam 11 and the second beam 12. Relative to the plug-in connection of the first beam 11 and the second beam 12, the first beam 11 and the second beam 12 can also contact each other through the outer surface, and two pin shafts 13 are used to pass through the axial holes 14 on the first beam 11 and the second beam 12 to fix the relative positions of the first beam 11 and the second beam 12. The connection method of the first beam 11 and the second beam 12 only needs to satisfy the requirement of making the first beam 11 and the second beam 12 slidably connected and the overall length of the crossbeam mechanism 1 can be adjusted, and no specific limitation is made here.

[0041] Optionally, the crossbeam mechanism 1 is used to be placed on the inner surface of the winding core.

[0042] In this embodiment, the crossbeam mechanism 1 is placed on the inner surface of the winding core cylinder, and the steel strip roll is inserted through the ejector mechanism 2 to fix the crossbeam mechanism 1 to the steel strip roll. No other fixing mechanism is needed, and the use is convenient.

[0043] Specifically, when placing the crossbeam mechanism 1, the center of the crossbeam mechanism 1 is set at the middle position of the steel strip roll along its axial direction, so that when the ejector mechanisms 2 at both ends are extended, the steel strip roll can be inserted at the same time, and the distance between adjacent roll layers can be widened from both sides of the axial direction of the steel strip roll.

[0044] Optionally, the steel strip coil opening device further comprises a controller, and the controller is electrically connected to the two ejector mechanisms 2 .

[0045] In this embodiment, a controller is provided, and the controller is electrically connected to the two ejector mechanisms 2. When in use, the controller controls the two ejector mechanisms 2 to extend simultaneously, so that when the ejector mechanisms 2 at both ends are extended, the steel strip roll can be inserted at the same time, and the distance between adjacent roll layers can be widened from both sides of the axis of the steel strip roll. When the ejector mechanisms 2 are contracted, they can also be detached from the steel strip roll at the same time.

[0046] Optionally, the driving member 22 is bolted to the crossbeam mechanism 1 .

[0047] In this embodiment, the driving member 22 is bolted to the beam mechanism 1 and fixed to the end of the beam mechanism 1, thereby improving the stability of the connection between the driving member 22 and the beam mechanism 1 and preventing the pressure of the ejector pin 21 and the driving member 22 on the steel strip from detaching from the beam mechanism 1 when the ejector pin 21 contacts the steel strip.

[0048] Specifically, the driving member 22 may also be welded to the beam mechanism 1 , and the connection method between the driving member 22 and the beam mechanism 1 is not specifically limited as long as the connection between the driving member 22 and the beam mechanism 1 is stable.

[0049] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
