When the operator pours the material into the molding drum 200, the material is concentrated at the bottom of the molding drum 200 due to the influence of gravity. As the molding drum 200 rotates faster, the material will gradually and evenly cover the circumferential side wall of the molding drum 200.

[0032] Specifically, after centrifugal molding is completed, the multi-axis drive mechanism 300 drives the sealing door 500 to move in a linear direction, so that the opening of the open cavity 400 is automatically opened.

[0038] like Figures 1 to 9 As shown, further, the temperature control mechanism 940 includes a heating component 941, a cooling component 942 and a monitoring unit 943, the heating component 941 is arranged on the inner wall of the open cavity 400 and is used to heat the forming drum 200; the cooling component 942 is arranged on the mounting seat 100 and is used to reduce the temperature of the open cavity 400, and the monitoring unit 943 is arranged at the end of the sealing door 500 facing the open cavity 400 and is used to monitor the temperature inside the open cavity 400.

[0041] like Figures 1 to 9 As shown, in the present embodiment, there are two groups of air inlet ducts 946, and the input ends of the two groups of air inlet ducts are connected to the air cooler 944, which is a variable frequency air conditioner; the pipe mouth of one group of air inlet ducts 946 is arranged at a position where the sealing door 500 is aligned with the rotation center of the forming drum 200, and the low-temperature gas output by the air cooler 944 can immediately perform heat exchange with the position of the forming drum 200 close to the transmission shaft 720 where the heat is higher when entering the open cavity 400; the pipe mouth of the other group of air inlet ducts 946 is arranged at a position where the sealing door 500 is aligned with the edge of the forming drum 200. Since the material will adhere to the inner wall of the forming drum 200 due to the influence of centrifugal force during the molding process, the low-temperature gas output by the air inlet duct 946 can immediately perform heat exchange with the position of the forming drum 200 close to the material after entering the open cavity 400, thereby effectively controlling the temperature of the material during the molding process.

[0042] like Figures 1 to 9 As shown, the number and position of the air inlet duct 946 and the air outlet duct 947 are flexible. The above embodiment is just one implementation method.

Among them, the thickness of the retaining ring 210 is much larger than the structural thickness of the material after centrifugal forming. For example, the material provided in this embodiment is a photovoltaic solder ribbon forming material.

[0051] The vertical drive assembly 330 includes a frame 331, a sprocket transmission component 332 and a second drive component 333. The frame 331 is arranged on the slider of the first guide rail 322. The frame 331 is fixedly connected to the output end of the first drive component 321.

[0052] The first driving member 321 drives the frame 331 in a horizontal direction. Figure 3 When the X-axis direction shown in the figure moves to the extreme position, a preset distance is set between the sealing portion 520 and the end face of the mounting seat 100 close to the open cavity 400. At this time, the second driving member 333 drives the connecting portion 510 through the sprocket transmission component 332 to drive the sealing portion 520 to move in the direction of the vertical end face of the frame 331. The sealing door 500 does not interfere with the mounting seat 100 during the vertical movement. When the sleeve 530 is aligned with the open cavity 400, the first driving member 321 drives the frame 331 to reset horizontally, and the sealing portion 520 is tightly fitted with the edge of the open cavity 400 to seal the open cavity 400. The operator can open the feed door 550 to input materials when the molding drum 200 is stationary; or open the feed door 550 to input materials when the driving source 700 drives the molding drum 200 to rotate at a preset speed to improve the structural uniformity of the material after molding. The sprocket transmission component 332 and the sprocket conveyor are technically formed and mature structures, and will not be described in detail in this embodiment.

[0053] After molding is completed, the first driving member 321 drives the sealing door 500 away from the opening cavity 400, and the second driving member 333 drives the sealing door 500 to move vertically upward to the top of the mounting seat 100, so that the opening of the opening cavity 400 is fully opened, and the operator can conveniently perform the unloading operation.

[0054] like Figures 1 to 9As shown, further, the mounting seat 100 is provided with a locking mechanism 110 for locking the sealing door 500 on the mounting seat 100. In this embodiment, the locking mechanism 110 includes a plurality of rotating telescopic structures 111 spaced circumferentially along the opening edge of the opening cavity 400. The output end of the rotating telescopic structure 111 is provided with a pressure rod 112, wherein the rotating telescopic structure 111 is a prior art capable of linear telescopic and rotational. For details, please refer to the document entitled "Combined Oil Cylinder with Integrated Telescopic and Rotating Function" with publication number CN221054055U, which will not be described in detail in this embodiment. Using the locking mechanism 110 to tightly press the sealing door 500 onto the opening cavity 400 is conducive to improving the sealing of the centrifugal operation. On the one hand, it prevents external dust from contaminating the material, and on the other hand, it can prevent accidental heat loss and improve the temperature control effect.
