Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0046] The following is combined with Figures 1 to 7 The present invention is described in detail with reference to specific embodiments.

[0047] like Figures 1 to 7 As shown, the present invention provides a method for preparing a metal calcium sheet. The calcium ingot in this embodiment is a cylindrical calcium ingot. The method for preparing the metal calcium sheet comprises the following steps:

[0048] Step A: The calcium ingot is transferred and loaded, and the calcium ingot is placed on the transfer device 1 in the primary sealed box. The transfer device 1 transfers the calcium ingot to the surface treatment device 2 in the secondary sealed box. The primary sealed box and the secondary sealed box are both filled with a mixed atmosphere of argon and hydrogen to prevent pure calcium from being oxidized during the subsequent treatment of the calcium ingot.

[0049] Step B: The surface of the calcium ingot is treated. The surface treatment device 2 cuts off the concave surface at the end of the calcium ingot by a cutting device, and then removes the outer surface oxide layer by a peeling device.

[0050] Step C: Make metal calcium sheets of required thickness, use cutting equipment to cut the calcium ingot with the concave surface and the surface oxide layer removed into metal calcium sheets of a certain thickness, convey the metal calcium sheets through the roller line 3, the roller line 3 conveys the metal calcium sheets to the rolling equipment 4, and then the metal calcium sheets are rolled into metal calcium sheets of target thickness through the rolling equipment 4, the roller line 3 continues to convey the metal calcium sheets leaving the rolling equipment 4, and the roller line 3 and the rolling equipment 4 are both placed in a secondary sealed box.

[0051] Step D: Cut and die-cut the metal calcium sheets to obtain metal calcium sheets with consistent size specifications. After rolling, the metal calcium sheets with target thickness are passed through the cutting device 5 to obtain regular rectangular metal calcium sheets. The die-cutting device 6 then die-cuts the regular metal calcium sheets into multiple metal calcium sheets with required specifications. The roller line 3 first transports the metal calcium sheets with target thickness to the cutting device 5, and then transports the regular rectangular metal calcium sheets to the die-cutting device 6. The cutting device 5 and the die-cutting device 6 are both placed in a secondary sealed box.

[0052] Step E: Automatically weigh and quantitatively package the metal calcium tablets of the required specifications. Automatically weigh the metal calcium tablets of the required specifications leaving the die-cutting device 6, and automatically and quantitatively package the metal calcium tablets into a collection tank for storage according to the demand of the metal reduction process. This process is completed by the quantitative packaging device 7, and the quantitative packaging device 7 is arranged in a secondary sealed box.

[0053] Through the above-mentioned preparation method of metal calcium tablets, there is no need for workers to manually sort the metal calcium tablets, which has the effect of reducing the labor intensity of workers and improving work efficiency. The preparation process of metal calcium tablets is carried out in a mixed atmosphere of argon and hydrogen. There are no oxidation spots on the surface of the metal calcium tablets prepared by this method, and metal calcium tablets of uniform specifications are prepared by cutting and die-cutting, which also saves the steps of manual sorting, improves production efficiency and reduces operating costs. This method realizes automatic quantitative packaging and storage of metal calcium tablets, and the weight of metal calcium tablets in each collection tank can be set according to production needs, which reduces the step of weighing calcium tablets for the subsequent metal reduction process and improves work efficiency.

[0054] In step A of this embodiment, the transfer device 1 includes a transfer cart and a transfer fork. The transfer cart is sent to the loading station, and the calcium ingots are transferred to the surface treatment device 2 using the transfer fork. The transfer device 1 can also use a truss robot or a robotic arm or other device that can realize the transfer of calcium ingots.

[0055] In step B of this embodiment, the cutting device in the surface treatment device 2 can be a circular saw cutting device, and the peeling device can be a lathe. The circular saw cutting device and the lathe device are used in conjunction with each other, and the concave surface of the calcium ingot is cut off by the circular saw cutting device, and the oxide layer on the surface of the calcium ingot is gradually removed by the turning tool on the lathe device. The equipment used in the surface treatment process is not limited to the use of circular saw cutting equipment and lathe equipment, and band sawing machines, laser cutting machines, milling peeling machines and other equipment can also be used in conjunction with each other to remove the concave surface and surface oxide layer of the calcium ingot.

[0056] In step C of this embodiment, the cutting equipment may use a circular saw cutting equipment, or may use a band saw machine or a laser cutting machine and other equipment capable of achieving cutting. The rolling equipment 4 may use a reversible rolling mill, which is arranged at the middle position of the roller line 3. The reversible rolling mill includes a rolling frame 41, an upper roller 42, a lower roller 43, a gap adjustment mechanism 44 and a roller transmission mechanism. The roller transmission mechanism is used to drive the upper roller 42 and the lower roller 43 to rotate respectively. The lower roller 43 is fixed in position. The distance between the upper roller 42 and the lower roller 43 can be adjusted up and down by the gap adjustment mechanism 44, thereby adjusting the roller gap. The roller line 3 transports the metal calcium sheet to the reversible rolling mill, the reversible rolling mill rolls the metal calcium sheet, and then adjusts the roller gap by the gap adjustment mechanism 44, transports the metal calcium sheet in the reverse direction, and rolls the metal calcium sheet again. After repeated rolling, the metal calcium sheet is rolled to the target thickness, and the roller line 3 transports the metal calcium sheet of the target thickness to the subsequent stage. In this process, multiple reversible rollers can also be used to roll the metal calcium sheets to the target thickness. In addition to using the roller line 3 to transport the metal calcium sheets, a conveyor belt device can also be used to transport the metal calcium sheets.

[0057] In step D of this embodiment, the cutting device 5 can use a cutting machine, which includes a conveying module unit 51, a cutting component 52 and two-side trimming components 53. The roller line 3 conveys the metal calcium sheet of the target thickness to the cutting machine, and the cutting component 52 cuts the metal calcium sheet. The two-side trimming components 53 cut off the incompletely regular edge materials on both sides of the metal calcium sheet of the target thickness. After cutting, a regular metal calcium sheet is formed. The roller line 3 conveys the regular metal calcium sheet to the die-cutting device 6.

[0058] The die-cutting device 6 can use a die-cutting machine, which includes a die-cutting frame 61, an upper die 62, a lower die 63, a die-cutting knife and a die-cutting transmission mechanism. The die-cutting knife is installed on the upper die 62, and the regular metal calcium sheets are transported to the die-cutting machine. The regular metal calcium sheets are placed on the lower die 63. The die-cutting transmission mechanism causes the upper die 62 to move downward, and the upper die 62 drives the die-cutting knife to apply moving pressure to the regular metal calcium sheets, thereby die-cutting the regular metal calcium sheets into multiple metal calcium sheets of required specifications.

[0059] In the process of making the metal calcium sheets of the required specifications in step D, the equipment used can also be a laser cutting machine or an air film cutting machine or other equipment that can cut the metal calcium sheets into the required specifications.

The filling robot 74 places the collecting tank on the weighing scale 73, and the metal calcium tablets of the required specifications fall into the receiving hopper 71 and are slowly distributed into the collecting tank through the linear vibrating screen 72. When the metal calcium tablets in the collecting tank reach the required weight, the linear vibrating screen 72 stops working, and the linear vibrating screen 72 stops distributing materials into the collecting tank. After the filling robot 74 closes the collecting tank cover with the collecting tank cover, the filling robot 74 puts the collecting tank into the stacker 8, and the stacker 8 sends the collecting tank to the storage warehouse in the primary sealed box for storage.

[0061] During the preparation of metal calcium sheets, the contents of argon atmosphere and hydrogen atmosphere are monitored in real time throughout the entire process to prevent oxidation of the metal calcium sheets and avoid hydrogen explosions, thereby ensuring production safety.

[0062] The implementation principle of the preparation method of a metal calcium sheet provided by the present invention is: the calcium ingot is transported and loaded, and the calcium ingot is placed on a transport device 1 in a primary sealed box. The transport device 1 transports the calcium ingot to a surface treatment device 2 in a secondary sealed box, and the surface of the calcium ingot is treated. The metal calcium sheet is rolled into a metal calcium sheet of target thickness by a rolling device 4, and the metal calcium sheet is cut and die-cut to obtain metal calcium sheets with consistent size specifications.
