[0006] The application provides a preparation method of metal calcium sheet, which comprises the following steps:

[0007] Step A: transporting and feeding the calcium ingot, the transporting device in the first-level sealed box transports the calcium ingot to the surface treatment device in the second-level sealed box;

[0008] Step B: treating the surface of the calcium ingot, the surface treatment device cuts off the recessed surface at the end of the calcium ingot by using a cutting device, and then removes the oxidation layer on the outer surface by using a peeling device;

[0009] Step C: To produce the required thickness of metallic calcium sheets, the calcium ingot is cut into metallic calcium sheets of a certain thickness using a cutting device. The metallic calcium sheets are then conveyed to the rolling equipment by a roller conveyor to roll the metallic calcium sheets into metallic calcium sheets of the target thickness. Both the roller conveyor and the rolling equipment are placed inside a secondary sealed box.

[0010] Step D: Cut and die-cut the calcium metal sheets. The calcium metal sheets are cut into regular rectangular sheets by the cutting equipment, and then the die-cutting equipment cuts the regular calcium metal sheets into multiple calcium metal sheets of the required specifications.

[0012] By adopting the above technical solution, manual sorting of metallic calcium flakes is eliminated, reducing labor intensity and improving work efficiency. The preparation process of the metallic calcium flakes is carried out in a mixed atmosphere of argon and hydrogen. The resulting flakes are free of oxide spots, and the standardized flakes are produced through cutting and die-cutting, eliminating the need for manual sorting and improving production efficiency while reducing operating costs. This method enables automated quantitative dispensing and storage of metallic calcium flakes. The weight of each collection tank can be set according to production needs, reducing the weighing steps in subsequent metal reduction processes and further improving efficiency.

[0013] Furthermore, in step A, the transfer device includes a transfer trolley and a transfer fork. The transfer trolley is sent to the loading station, and then the transfer fork is used to transfer the calcium ingot to the surface treatment device.

[0014] By adopting the above technical solution, calcium ingots are placed on a transfer trolley, and the calcium ingots on the transfer trolley are transferred to a surface treatment device with the help of forks. The surface treatment device then treats the surface of the calcium ingots.

[0015] Furthermore, in step B, the cutting equipment is a circular saw cutting equipment, and the peeling equipment is a lathe. The circular saw cutting equipment and the lathe are used together to remove the concave surface and oxide layer of the calcium ingot.

[0016] By adopting the above technical solution, the circular saw cutting equipment and the lathe equipment are used together. The circular saw cutting equipment removes the concave surface of the calcium ingot, and the lathe tool on the lathe equipment gradually removes the oxide layer on the surface of the calcium ingot.

[0017] Furthermore, in step B, the cutting equipment is a band saw or a laser cutting machine, and the peeling equipment is a milling peeling machine. The cutting equipment and the peeling equipment are used together to remove the concave surface and oxide layer of the calcium ingot.

[0018] By adopting the above technical solution, equipment such as band saws, laser cutters, and milling peeling machines are used in combination to remove the concave surface of calcium ingots and remove the oxide layer on the surface of calcium ingots.

[0019] Furthermore, in step C, the rolling equipment is a reversible rolling mill located in the middle of the roller table, which is used to roll the calcium metal sheet into a calcium metal sheet of the target thickness.

[0020] By adopting the above technical solution, the roller conveyor transports the calcium metal sheet to the reversible rolling mill, which rolls the calcium metal sheet. The reversible rolling mill can reverse the flow of the calcium metal sheet and roll it again. After repeated rolling, the calcium metal sheet can be rolled to the target thickness.

[0021] Furthermore, the reversible rolling mill includes a rolling stand, an upper roll, a lower roll, a gap adjustment mechanism, and a roll transmission mechanism. The roll transmission mechanism is used to drive the upper roll and the lower roll to rotate respectively. The roller conveyor transports the calcium metal sheet into the reversible rolling mill. The gap adjustment mechanism adjusts the roll gap, and the calcium metal sheet is transported in the reverse direction to be rolled again. After repeated rolling, the calcium metal sheet is rolled to the target thickness.

[0022] By adopting the above technical solution, the roll transmission mechanism is used to drive the upper and lower rolls to rotate respectively. The lower roll is fixed in position, and the distance between the upper and lower rolls can be adjusted up and down by the gap adjustment mechanism, thereby adjusting the roll gap. The roller conveyor transports the calcium metal sheet to the reversible rolling mill, which rolls the calcium metal sheet. Then, the gap adjustment mechanism is used to adjust the roll gap, and the calcium metal sheet is transported in the reverse direction. The calcium metal sheet is rolled again. After repeated rolling, the calcium metal sheet is rolled to the target thickness. The roller conveyor then transports the calcium metal sheet of the target thickness to the next stage.

[0023] Furthermore, in step D, the cutting equipment is a cutting machine, which cuts the target thickness of the calcium metal sheet into regular calcium metal sheets. The die-cutting equipment is a die-cutting machine, which die-cuts the regular calcium metal sheet into multiple calcium metal sheets of the required specifications.

[0024] By adopting the above technical solution, the cutting machine removes the edge material of the calcium metal sheet, and after cutting, it forms a regular calcium metal sheet. The roller conveyor transports the regular calcium metal sheet to the die-cutting machine, which then die-cuts the regular calcium metal sheet into multiple calcium metal sheets of the required specifications.

[0025] Furthermore, the cutting machine includes a conveying module unit, a cutting component, and two side trimming components. The roller conveyor conveys the metal calcium sheet of the target thickness into the cutting machine. The cutting component cuts the metal calcium sheet, and the two side trimming components remove the irregular edges on both sides of the metal calcium sheet of the target thickness, forming a regular metal calcium sheet after cutting. The die-cutting machine includes a die-cutting frame, an upper die, a lower die, a die-cutting blade, a die-cutting transmission mechanism, and a conveying module unit. The die-cutting blade is installed on the upper die. The regular metal calcium sheet is conveyed into the die-cutting machine. The die-cutting transmission mechanism causes the upper die to move downward, die-cutting the regular metal calcium sheet into multiple metal calcium sheets of the required specifications.

[0026] By adopting the above technical solution, the roller conveyor transports the calcium metal sheet of the target thickness to the cutting machine. The cutting component cuts the calcium metal sheet, and the side trimming components remove the irregular edges on both sides of the calcium metal sheet of the target thickness. After cutting, a regular calcium metal sheet is formed. The roller conveyor transports the regular calcium metal sheet to the die-cutting machine. The regular calcium metal sheet is placed in the lower die, and the die-cutting transmission mechanism causes the upper die to move downward. The upper die drives the die-cutting blade to apply moving pressure to the regular calcium metal sheet, and the regular calcium metal sheet is die-cut into multiple calcium metal sheets of the required specifications.

[0027] Furthermore, in step E, the quantitative dispensing equipment includes a receiving hopper, a linear vibrating screen, a weighing balance, a dispensing robot, a collection tank temporary storage position, and a collection tank cover temporary storage position. The dispensing robot places the collection tank on the weighing balance. After the required size of the calcium metal sheets passes through the receiving hopper, it enters the collection tank through the linear vibrating screen. When the calcium metal sheets in the collection tank reach the required weight, the linear vibrating screen stops working. After the dispensing robot closes the collection tank cover, it places the collection tank into a stacker crane, which then transports the collection tank to the storage warehouse in the primary sealed box for storage.

[0028] By adopting the above technical solution, the required size of metallic calcium flakes enters the receiving hopper and falls into the linear vibrating screen. The metallic calcium flakes pass through the linear vibrating screen into the collection tank placed above the weighing balance. When the metallic calcium flakes in the collection tank reach the required weight, the linear vibrating screen stops working and stops feeding material into the collection tank. Then, the packaging robot closes the collection tank lid, and the collection tank with the lid closed is sent into the stacker crane by the packaging robot. The stacker crane then transfers the collection tank to the storage warehouse for storage.

[0029] Furthermore, the primary and secondary sealed chambers contain a mixed atmosphere of argon and hydrogen, and the content of argon and hydrogen atmospheres is monitored in real time throughout the preparation process.

[0030] By adopting the above technical solution, the content of argon and hydrogen atmospheres is monitored in real time throughout the process, preventing the oxidation of the calcium metal sheets and avoiding hydrogen explosions, thus ensuring production safety.

[0045] The technical solutions in 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 protection scope of the present invention.

[0046] The following is in conjunction with the appendix Figures 1 to 7 The invention is described in detail with specific embodiments.

[0047] like Figures 1 to 7 As shown, this invention provides a method for preparing metallic calcium sheets. In this embodiment, the calcium ingot is cylindrical. The method for preparing metallic calcium sheets includes the following steps:

[0048] Step A: Transfer and load the calcium ingots. Place the calcium ingots on the transfer device 1 inside the primary sealed box. The transfer device 1 transfers the calcium ingots to the surface treatment device 2 inside the secondary sealed box. Both the primary and secondary sealed boxes are filled with a mixed atmosphere of argon and hydrogen to prevent the oxidation of pure calcium during the subsequent processing of the calcium ingots.

[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 using a cutting device, and then removes the oxide layer on the outer surface using a peeling device.

[0050] Step C: To produce the required thickness of metallic calcium sheets, the calcium ingot with the concave surface and surface oxide layer removed is cut into metallic calcium sheets of a certain thickness using a cutting device. The metallic calcium sheets are then conveyed by roller conveyor 3 to the rolling mill 4, where they are rolled to the target thickness. Roller conveyor 3 continues to convey the metallic calcium sheets leaving the rolling mill 4. Both roller conveyor 3 and the rolling mill 4 are placed in a secondary sealed box.

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

[0052] Step E: Automatically weigh and quantitatively dispense the required specifications of metallic calcium flakes. Automatically weigh the required specifications of metallic calcium flakes leaving the die-cutting equipment 6, and automatically dispense the metallic calcium flakes into the collection tank for storage according to the required amount of the metal reduction process. This process is completed by the quantitative dispensing equipment 7, which is set in a secondary sealed box.

[0053] The above-described method for preparing metallic calcium flakes eliminates the need for manual sorting, reducing labor intensity and increasing work efficiency. The preparation process is carried out in a mixed atmosphere of argon and hydrogen, resulting in flakes without oxide spots. Furthermore, the method produces uniformly sized flakes through cutting and die-cutting, eliminating manual sorting and improving production efficiency while reducing operating costs. This method also enables automated quantitative dispensing and storage of metallic calcium flakes. The weight of each collection tank can be set according to production needs, reducing the weighing steps in subsequent metal reduction processes and further improving efficiency.

[0054] In step A of this embodiment, the transfer device 1 includes a transfer trolley and a forklift. The transfer trolley is sent to the loading station, and the forklift is used to transfer the calcium ingot to the surface treatment device 2. The transfer device 1 can also use a gantry robot or a robotic arm or other device that can transfer calcium ingots.

[0055] In step B of this embodiment, the cutting device in the surface treatment apparatus 2 can be a circular saw, and the peeling device can be a lathe. The circular saw and the lathe are used together. The circular saw cuts off the concave surface of the calcium ingot, and the lathe tool removes the oxide layer from the surface of the calcium ingot step by step. The equipment used in the surface treatment process is not limited to circular saws and lathes; band saws, laser cutters, and milling peeling machines can also be used in conjunction to remove the concave surface and oxide layer of the calcium ingot.

[0056] In step C of this embodiment, the cutting equipment can be a circular saw, a band saw, or a laser cutter, or any other equipment capable of cutting. The rolling equipment 4 can be a reversible rolling mill, located in the middle of the roller conveyor 3. The reversible rolling mill includes a rolling frame 41, an upper roll 42, a lower roll 43, a gap adjustment mechanism 44, and a roll transmission mechanism. The roll transmission mechanism drives the upper roll 42 and lower roll 43 to rotate respectively. The lower roll 43 is fixed in position. The distance between the upper roll 42 and lower roll 43 can be adjusted up and down by the gap adjustment mechanism 44, thereby adjusting the roll gap. The roller conveyor 3 conveys the calcium metal sheet into the reversible rolling mill, which rolls the calcium metal sheet. Then, the gap adjustment mechanism 44 adjusts the roll gap, reverses the flow of the calcium metal sheet, and rolls it again. After repeated rolling processes, the calcium metal sheet is rolled to the target thickness. The roller conveyor 3 then conveys the calcium metal sheet of the target thickness to subsequent rolling operations. In this process, multiple reversible rolling mills can be used to roll the calcium metal sheets to the target thickness. In addition to using roller conveyor 3 to transport the calcium metal sheets, a conveyor belt can also be used to transport the calcium metal sheets.

[0057] In step D of this embodiment, the cutting device 5 can be a cutting machine, which includes a conveying module unit 51, a cutting component 52, and two side trimming components 53. The roller conveyor 3 conveys the metal calcium sheet of the target thickness into the cutting machine. The cutting component 52 cuts the metal calcium sheet, and the two side trimming components 53 remove the irregular edges on both sides of the metal calcium sheet of the target thickness. After cutting, a regular metal calcium sheet is formed. The roller conveyor 3 conveys the regular metal calcium sheet into the die-cutting device 6.

[0058] The die-cutting equipment 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 blade, and a die-cutting transmission mechanism. The die-cutting blade is installed on the upper die 62. The regular calcium metal sheets are fed into the die-cutting machine and placed in the lower die 63. The die-cutting transmission mechanism causes the upper die 62 to move downward. The upper die 62 drives the die-cutting blade to apply moving pressure to the regular calcium metal sheets, and the regular calcium metal sheets are die-cut into multiple calcium metal sheets of the required specifications.

[0059] In step D, during the production of the required size of the metallic calcium sheet, the equipment used can also be a laser cutter or an air-film cutter, which can cut the metallic calcium sheet into the required size.

[0060] In step E of this embodiment, the quantitative dispensing equipment 7 includes a receiving hopper 71, a linear vibrating screen 72, a weighing balance 73, a dispensing robot 74, a collection tank temporary storage position 75, and a collection tank cover temporary storage position 76. The dispensing robot 74 places the collection tank on the weighing balance 73. The required size of the metallic calcium flakes falls into the receiving hopper 71 and is slowly fed into the collection tank by the linear vibrating screen 72. When the metallic calcium flakes in the collection tank reach the required weight, the linear vibrating screen 72 stops working and stops feeding material into the collection tank. After the dispensing robot 74 closes the collection tank cover, it places the collection tank into the stacker crane 8, which then sends the collection tank to the storage warehouse in the primary sealed box for storage.

[0061] During the preparation of metallic calcium sheets, the content of argon and hydrogen atmospheres is monitored in real time throughout the process to prevent oxidation of the metallic calcium sheets and avoid hydrogen explosions, thus ensuring production safety.

[0062] The implementation principle of the method for preparing metallic calcium sheets provided by the present invention is as follows: calcium ingots are transferred and fed to a transfer device 1 in a primary sealed box. The transfer device 1 transfers the calcium ingots to a surface treatment device 2 in a secondary sealed box for surface treatment. The surface of the calcium ingots is then treated. The metallic calcium sheets are rolled into metallic calcium sheets of the target thickness by a rolling equipment 4. The metallic calcium sheets are then cut and die-cut to obtain metallic calcium sheets with consistent dimensions. The required specifications of metallic calcium sheets are automatically weighed, quantitatively packaged, and stored. The resulting metallic calcium sheets have uniform specifications, no oxide spots on the surface, and do not require manual sorting and packaging, greatly improving production efficiency.

[0063] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the nature and scope of the present invention. Various modifications made to the above embodiments by those skilled in the art after reading this specification are all within the scope of protection of the present invention.
