Description

Technical Field

[0001] This invention belongs to the field of sheet-forming machine technology, specifically, it relates to a vacuum sheet-forming machine. Background Technology

[0002] In the material processing of chemical, pharmaceutical, and food industries, vacuum flaking machines are key equipment for achieving rapid condensation and flaking of high-temperature molten materials. Their core requirements are to ensure that the material can stably complete flaking in a vacuum environment, while avoiding oxidation caused by contact with air, ensuring product purity and quality, and maintaining long-term efficient operation of the equipment.

[0003] Traditional sheet forming machines often use a single-seal design at the connection between the rotating rod and the housing, resulting in poor sealing. During operation, the rotating rod needs to rotate continuously at high speed, causing friction and wear on the seals. Simultaneously, the rotating rod experiences slight radial runout due to material resistance and its own weight. The single-seal structure lacks "elastic compensation" and cannot adjust its fit according to the dynamic offset of the rotating rod. After wear, the seal gap rapidly expands, forming gaps and causing air leakage. This allows outside air to enter the equipment, leading to oxidation of the material upon contact with air, causing material deterioration and severely impacting product quality.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0020] Example 1: like Figures 1 to 10As shown, the vacuum slagging machine includes a mounting frame 1, a protective housing 11 on top of the mounting frame 1, a feed inlet 111 on top of the protective housing 11, a discharge outlet 112 at the bottom of the protective housing 11, a left mounting plate 13 and a right mounting plate 131 inside the protective housing 11, a servo motor 12 on one side wall of the protective housing 11, a rotating rod 121 at the output end of the servo motor 12, the rotating rod 121 movably passing through the left mounting plate 13, a drum 122 at the end of the rotating rod 121 away from the servo motor 12, and a rotating shaft 123 at the end of the drum 122 away from the rotating rod 121, the rotating shaft 123 being located on the inner wall of the protective housing 11; a mounting housing 2 on one side wall of the protective housing 11, a fixing ring 21 inside the mounting housing 2, and an inner ring of the fixing ring 21... A circular slot is provided, and a rotating ring 211 is sealed and inserted into the inner cavity of the circular slot. The rotating ring 211 is set on the rotating rod 121. A circular slot is provided on the top of the mounting housing 2, and a circular mounting cylinder 212 is set on the top of the mounting housing 2. A circular fixing cylinder 23 is set on the top of the circular mounting cylinder 212. A rotating rod 24 is set on the top of the circular fixing cylinder 23. A bearing 242 is set on the end of the rotating rod 24 away from the circular fixing cylinder 23, and the bearing 242 is set on the inner wall of the protective housing 11. A circular placement slot 219 is provided on the side wall of the mounting housing 2 near the rotating drum 122, and a left sealing gasket 313 is set in the inner cavity of the circular placement slot 219. A right sealing gasket 311 is set on the rotating rod 121, and the right sealing gasket 311 and the left sealing gasket 313 fit together. The rotating rod 121 is driven to rotate by the servo motor 12, and the rotating rod 121 drives the rotating drum 122. With the help of the rotating shaft 123, the rotating drum 122 operates stably, which helps the material to condense and condense. With the mounting frame 1 as the base support, the protective shell 11, together with the inlet 111 and outlet 112, enables the orderly entry and exit of materials. The left mounting plate 13 and right mounting plate 131 in the inner cavity stably support the rotating rod 121 and the rotating drum 122. The condenser tube in the rotating drum 122 optimizes heat transfer, reduces the heat load per unit heat transfer area, effectively improves production efficiency, reduces equipment investment, and improves the problems of low efficiency and high investment in traditional flaking machines. The fixing ring 21 in the mounting shell 2 and the rotating ring 211 on the rotating rod 121 form a preliminary seal. With the fit and seal of the left sealing gasket 313 and the right sealing gasket 311, it can prevent air leakage at the rotating rod 121 from causing material oxidation or leakage of toxic gases, solving the problem of insufficient sealing in traditional flaking machines. At the same time, the overall vacuum structure can also ensure the purity of materials, which is superior to that of traditional flaking machines.

[0021] like Figures 1 to 3 As shown, in a specific embodiment, a placement slot 214 and an installation slot 213 are respectively provided on one side wall of the mounting housing 2 and the circular mounting cylinder 212. The placement slot 214 and the installation slot 213 are interconnected, and the placement slot 214 movably passes through the mounting frame 1. In this configuration, the positions of the placement slot 214 and the installation slot 213 are determined.

[0022] Example 2: The difference between Embodiment 1 and this embodiment is that: Figures 1 to 3 and Figures 5 to 10 As shown, in the vacuum slagging machine, a circular piston plate 22 is installed inside the circular mounting cylinder 212. The initial position of the circular piston plate 22 is located at the mounting slot 213. A return spring 221 is installed above the circular piston plate 22, with the other end of the return spring 221 attached to the inner wall of the circular mounting cylinder 212. A moving rod 222 is installed above the circular piston plate 22, and the moving rod 222 moves through the circular mounting cylinder 212. In this configuration, as gas accumulates to a certain amount, it will compress the circular piston plate 22 at the connection between the mounting housing 2 and the circular mounting cylinder 212, causing it to move upward. After the circular piston plate 22 moves, the mounting slot 213 is exposed, allowing gas to be discharged. At the same time, the upward movement of the circular piston plate 22 will cause the moving rod 222 connected above it to move upward synchronously.

[0023] like Figures 1 to 9 As shown, in a specific embodiment, the bottom of the circular fixed cylinder 23 has an inclined surface 231, and an arc-shaped slide rail 232 is provided at the bottom of the inclined surface 231. A sliding block 233 is slidably mounted on the arc-shaped slide rail 232, and a moving rod 222 is provided at the bottom of the sliding block 233. In this configuration, when the moving rod 222 moves upward, it will press against the inclined surface 231 at the bottom of the circular fixed cylinder 23. With the assistance of the sliding block 233 sliding on the arc-shaped slide rail 232 at the bottom of the circular fixed cylinder 23, the rotating rod 24, and the bearing 242, the rotating rod 24 rotates.

[0024] like Figures 1 to 3 and Figures 5 to 9 As shown, furthermore, a guide groove 241 is provided on the rotating rod 24, and a guide slider is slidably arranged in the inner cavity of the guide groove 241. A guide sleeve 243 is provided on the guide slider, and the guide sleeve 243 is sleeved on the outer wall of the rotating rod 24. In this arrangement, it is ensured that when the moving rod 222 moves upward, it will press the inclined surface 231 opened at the bottom of the circular fixed cylinder 23. With the assistance of the sliding block 233 sliding on the arc-shaped slide rail 232 at the bottom of the circular fixed cylinder 23, the rotating rod 24, and the bearing 242, the rotating rod 24 rotates.

[0025] like Figures 1 to 3 and Figures 5 to 9As shown, further, a movable groove 25 is provided on the side wall of the left mounting plate 13 away from the right mounting plate 131. A sliding rod 251 is slidably disposed in the inner cavity of the movable groove 25. The end of the sliding rod 251 away from the movable groove 25 is disposed on the guide sleeve 243. The sliding rod 251 is used to assist the guide sleeve 243 in moving vertically. In this configuration, it is ensured that during the rotation of the rotating rod 24, the guide slider sliding in the inner cavity of the guide groove 241 on its surface will drive the guide sleeve 243 sleeved on the outer wall of the rotating rod 24 to move. At the same time, the sliding rod 251 connected to the guide sleeve 243 will slide vertically along the movable groove 25 on the left mounting plate 13.

[0026] Example 3: The difference between Embodiment 2 and this embodiment is that: Figures 1 to 3 and Figures 5 to 9 As shown, in the vacuum slagging machine, a left sealing plate 215 and a right sealing plate 216 are respectively provided on the two side walls of the rotating ring 211. The left sealing plate 215 and the right sealing plate 216 are annular and are located in the inner cavity of the fixed ring 21. The left sealing plate 215 and the right sealing plate 216 are used to seal the fixed ring 21 and the rotating ring 211. In this configuration, when the rotating rod 121 at the servo motor 12 leaks due to aging between it and the protective housing 11, external gas will enter the inner cavity of the protective housing 11 and then seep into the inner cavity of the mounting housing 2. At this time, the fixed ring 21 and the rotating ring 211 will first initially block the gas from entering, and the left sealing plate 215 and the right sealing plate 216 will further enhance the sealing effect and reduce the continued gas penetration.

[0027] like Figures 1 to 3 and Figures 5 to 9 As shown, in a specific embodiment, four rails 312 are provided on the side wall of the rotating rod 121. The four rails 312 are distributed in a circle, and a left sealing gasket 313 is provided on the four rails 312. The four rails 312 are used to assist the horizontal movement of the left sealing gasket 313. In this configuration, the opening position of the rails 312 is determined.

[0028] like Figures 1 to 3 and Figures 5 to 9As shown, further, a drive plate 3 is provided on the side wall of the right sealing gasket 311 away from the left sealing gasket 313. A drive plate 3 is fitted to one end of the drive plate 3 away from the left sealing gasket 313. A swing arm 252 is provided above the drive plate 3. Two multi-stage telescopic rods 31 are provided at the end of the drive plate 3 away from the left sealing gasket 313. The two multi-stage telescopic rods 31 are symmetrical to each other, and the ends of the two multi-stage telescopic rods 31 away from the left sealing gasket 313 are mounted on the left mounting plate 13. A cavity is formed inside the drum 122, and a condenser tube is installed inside the cavity. In this configuration, when the sliding rod 251 moves vertically, it drives the swing arm 252 connected above it. The swing arm 252 pushes the drive plate 3, which is in contact with the side wall of the right sealing gasket 311 away from the left sealing gasket 313. With the assistance of two symmetrical multi-stage telescopic rods 31 set at the end of the drive plate 3 away from the left sealing gasket 313, the drive plate 3 moves horizontally. The horizontal movement of the drive plate 3 pushes the right sealing gasket 311. With the assistance of the four circumferentially distributed tracks 312 on the side wall of the rotating rod 121, the right sealing gasket 311 moves horizontally and is tightly pressed against the left sealing gasket 313, thus achieving resealing. This, to a certain extent, prevents the oxidation of materials due to sealing failure during the operation of the vacuum slagging machine.

[0029] The implementation principle of the vacuum slagging machine of the present invention is as follows: The vacuum flaking machine is supported by a mounting frame 1, on which a protective shell 11 is mounted. The top of the protective shell 11 has a feed port 111 for material input, and the bottom has a discharge port 112 for finished product discharge. The inner cavity of the protective shell 11 is also fixed with a left mounting plate 13 and a right mounting plate 131. At the same time, a servo motor 12 is mounted on one side wall. The output end of the servo motor 12 is connected to a rotating rod 121. The rotating rod 121 moves through the left mounting plate 13 and is connected to one end of a rotating drum 122. The other end of the rotating drum 122 is mounted on the inner wall of the protective shell 11 through a rotating shaft 123. The inside of the rotating drum 122 has a cavity, and the condenser tube installed in the cavity can realize the condensation and flaking of materials. During normal operation of the equipment, the servo motor 12 drives the rotating rod 121 to rotate the drum 122. After the material enters the inner cavity of the protective shell 11 from the feed port 111, it comes into contact with the surface of the drum 122. With the help of the cooling effect of the condenser tube, it completes the condensation and is finally discharged from the discharge port 112. The inner cavity of the housing 2 is fixed with a fixing ring 21. The circular groove of the inner ring of the fixing ring 21 is sealed with a rotating ring 211 installed on the rotating rod 121. The two side walls of the rotating ring 211 are respectively provided with a left sealing plate 215 and a right sealing plate 216 in the shape of a ring. The left sealing plate 215 and the right sealing plate 216 are both located in the inner cavity of the fixing ring 21, which can initially enhance the sealing between the fixing ring 21 and the rotating ring 211. When air leakage occurs between the rotating rod 121 at the servo motor 12 and the protective housing 11 due to aging, external gas will enter the inner cavity of the protective housing 11 and then seep into the inner cavity of the mounting housing 2. At this time, the fixed ring 21 and the rotating ring 211 will first block the gas from entering, and the left sealing plate 215 and the right sealing plate 216 will further enhance the sealing effect and reduce the continued gas penetration. If air leakage also occurs between the rotating ring 211 and the fixed ring 21 due to aging, gas will enter the inner cavity of the fixed ring 21 from the left sealing plate 215. As the gas accumulates to a certain amount, it will squeeze the circular piston plate 22 (the initial position of the circular piston plate 22 is located at the mounting slot 213) at the connection between the mounting housing 2 and the circular mounting cylinder 212 and move upward. After the circular piston plate 22 moves, the mounting slot 213 is exposed, and the gas can be discharged. At the same time, the upward movement of the circular piston plate 22 will drive the moving rod 222 connected above it to move upward synchronously. When the moving rod 222 moves upward, it will press the inclined surface 231 opened at the bottom of the circular fixed cylinder 23. With the assistance of the sliding block 233 sliding on the arc-shaped slide rail 232 at the bottom of the circular fixed cylinder 23, the rotating rod 24 and the bearing 242, the rotating rod 24 rotates. During the rotation of the rotating rod 24, the guide slider sliding in the inner cavity of the guide groove 241 opened on its surface will drive the guide sleeve 243 sleeved on the outer wall of the rotating rod 24 to move. At the same time, the sliding rod 251 connected to the guide sleeve 243 will slide vertically along the moving groove 25 opened on the left mounting plate 13. When the sliding rod 251 moves vertically, it drives the swing arm 252 connected above it. The swing arm 252 pushes the drive plate 3, which is in contact with the side wall of the right sealing gasket 311 away from the left sealing gasket 313. With the assistance of two symmetrical multi-stage telescopic rods 31 set at the end of the drive plate 3 away from the left sealing gasket 313, the drive plate 3 moves horizontally. The horizontal movement of the drive plate 3 pushes the right sealing gasket 311. With the assistance of the four circumferentially distributed tracks 312 on the side wall of the rotating rod 121, the right sealing gasket 311 moves horizontally and is tightly pressed against the left sealing gasket 313 to achieve resealing. This, to a certain extent, prevents the material from oxidizing due to sealing failure during the operation of the vacuum slagging machine. Based on the above, the mounting frame 1 serves as the basic support, and the protective shell 11, along with the inlet 111 and outlet 112, enables the orderly entry and exit of materials. The left mounting plate 13 and right mounting plate 131 within the inner cavity stably support the rotating rod 121 and the drum 122. The condenser tube inside the drum 122 optimizes heat transfer, reduces the heat load per unit heat transfer area, effectively improves production efficiency, reduces equipment investment, and addresses the problems of low efficiency and high investment in traditional flaking machines. The fixing ring 21 inside the mounting shell 2 and the rotating ring 211 on the rotating rod 121 form a preliminary seal. Combined with the fitting seal of the left sealing gasket 313 and the right sealing gasket 311, this prevents air leakage at the rotating rod 121 from causing material oxidation or leakage of toxic gases, thus solving the problem of insufficient sealing in traditional flaking machines. At the same time, the overall vacuum structure can also ensure the purity of the materials, which is superior to that of traditional flaking machines.
