In the production process, the pulverizing device, as a key equipment, plays a vital role. The main function of the pulverizing device is to finely pulverize the raw materials to ensure that the particle size of the raw materials meets the requirements of the subsequent molding process.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 9 As shown, the present invention provides an isostatic graphite production system for semiconductors, and the production system is as follows:

[0035] S1: First, the operator can select high-purity graphite raw materials, such as natural graphite or artificial graphite, and then use a crushing device and a screening device to crush and screen the graphite;

[0036] S2: The pretreated graphite raw material can then be mixed evenly with an appropriate amount of additives and then placed in an isostatic press for molding. During the molding process, parameters such as pressure, temperature and time need to be controlled to ensure the quality of the graphite blank.

[0037] S3: Then the formed graphite blank is placed in a sintering furnace for high-temperature sintering. During the sintering process, impurities in the graphite raw material will be removed, and the crystallinity of the graphite will be improved, thereby enhancing the strength and conductivity of the graphite;

[0038] S4: Finally, the sintered graphite is cut, ground and processed to obtain graphite products that meet the requirements. After processing, the product is tested for various performance indicators to ensure product quality.

[0039] like Figures 1 to 9 As shown, a semiconductor isostatic graphite production device, the pulverizing device in S1 includes a pulverizing box 1, a feeding pipe 2 is arranged at the top of the pulverizing box 1, a guide plate 3 is arranged inside the pulverizing box 1, and a pulverizing assembly 4 is arranged inside the guide plate 3;

[0040] The control mechanism is arranged inside the crushing box 1, and the control mechanism includes a limit rod 5, which is fixedly connected to the inside of the crushing box 1. A sealing plate 6 is slidably mounted on the surface of the limit rod 5, and a fixing groove 7 is opened on one side of the sealing plate 6. A motor 8 is fixedly installed at the top of the inner cavity of the crushing box 1, and a rotating disk 9 is fixedly installed at the output end of the motor 8. A push rod 10 is rotatably hinged at the top of the inner cavity of the crushing box 1, and a protrusion 11 located inside the push rod 10 is fixedly installed on one side of the rotating disk 9, and a protrusion 2 12 located inside the fixing groove 7 is fixedly installed on one side of the push rod 10.

[0041] The operator pours the raw material into the feed pipe 2, and the raw material passes through the feed pipe 2 and falls into the guide plate 3, and then the guide plate 3 guides the raw material to the surface of the crushing component 4, and then the crushing component 4 can be driven to crush the raw material;

[0042] While the raw material falls inside the guide plate 3, the motor 8 can be driven to rotate the rotating disk 9, and the rotating disk 9 will drive the protrusion 11 to move inside the push rod 10, and the protrusion 11 will push the push rod 10 to swing back and forth. While the push rod 10 swings, the push rod 10 will drive the protrusion 2 12 to move inside the fixed groove 7, and then the protrusion 2 12 will push the blocking plate 6 to move back and forth on the surface of the limit rod 5. In the process of the reciprocating movement of the blocking plate 6, the amount of material discharged can be controlled. Finally, the motor 8 is driven to make the blocking plate 6 swing back and forth, and then the amount of material discharged can be controlled, so that the raw material can be more evenly distributed between the crushing components 4, so that the crushing component 4 can perform the crushing operation more effectively, improve the crushing efficiency, and avoid the raw material falling on the surface of the crushing component 4 at one time, thereby reducing the load of the crushing component 4 and extending its service life.

[0043] like Figure 5 , Figure 6 , Figure 7 and Fig. 9 As shown, a swing mechanism is arranged on one side of the outer surface of the crushing box 1, and the swing mechanism includes a protective shell 13, which is fixedly connected to one side of the outer surface of the crushing box 1, and one side of the outer surface of the crushing box 1 is rotatably connected to a gear 14 located inside the protective shell 13, and one side of the gear 14 is fixedly installed with a swing plate 15 located at the bottom end of the crushing assembly 4, and a push rod 2 16 is arranged inside the protective shell 13, and a rack 17 meshing with the gear 14 is fixedly installed on one side of the outer surface of the push rod 2 16, and a motor 2 18 is fixedly installed in the inner cavity of the protective shell 13, and a push rod 3 19 is fixedly installed on the output end of the motor 2 18, and a protrusion 3 20 located inside the push rod 2 16 is fixedly installed on one side of the push rod 3 19.

[0044] Through the design of the swing mechanism, after the crushing assembly 4 completes the crushing of the raw materials, the motor 2 18 can be driven to rotate the push rod 3 19, and the push rod 3 19 will drive the protrusion 3 20 to move inside the push rod 2 16, and the protrusion 3 20 will push the rack 17 to move back and forth. Because the rack 17 is meshed with the gear 14, the moving rack 17 will drive the gear 14 to rotate back and forth, and the gear 14 will drive the swing plate 15 to swing back and forth, and then the crushed raw materials will fall on the top of the swing plate 15. Since the swing plate 15 is swinging, the swing plate 15 will evenly guide the raw materials to the inside of the storage assembly, and finally, the swing plate 15 will swing back and forth by driving the motor 2 18, so as to avoid the crushed raw materials from accumulating inside the storage assembly, thereby ensuring that the raw materials are evenly distributed in the storage assembly, avoiding space waste caused by local accumulation, and maximizing the use of the capacity of the storage assembly.

[0045] like Fig. 9As shown, a support groove 21 located inside the protective shell 13 is opened on one side of the outer surface of the crushing box 1, and a support block 22 is slidably connected inside the support groove 21, and one side of the support block 22 is fixedly connected to one side of the push rod 16, and the support block 22 is T-shaped.

[0046] Through the design of the support groove 21 and the support block 22, when the push rod 16 moves, the push rod 16 will drive the support block 22 to move inside the support groove 21, and the support block 22 is a T-shaped design, and the surface of the support block 22 fits with the inner wall of the support groove 21, so that the push rod 16 can be limited and supported to avoid position deviation when the push rod 16 moves.

[0047] like Figure 2 As shown, a baffle 23 located on one side of the crushing assembly 4 is fixedly mounted on the bottom end of the guide plate 3, and a guide ring 24 located on the top of the crushing assembly 4 is fixedly mounted on one side of the outer surface of the baffle 23, and the guide ring 24 is of conical design.

[0048] Through the design of the baffle 23 and the guide ring 24, the guide plate 3 will transfer the raw material to the inside of the guide ring 24. Since the guide ring 24 is conical in design, the guide ring 24 will guide the raw material to the crushing part of the crushing component 4, ensuring that the crushing component 4 can crush the raw material. The baffle 23 is set on one side of the crushing component 4, which can block the raw material and prevent the uncrushed raw material from escaping from the surface of the crushing component 4.

[0049] like Figure 2 and Figure 8 As shown, a collecting box 25 is fixedly mounted on the surface of the crushing box 1 , a suction assembly 26 located at the top of the guide ring 24 is fixedly mounted on one side of the collecting box 25 , and a collecting trough 27 is slidably connected inside the collecting box 25 .

[0050] Through the design of the collecting box 25, the suction component 26 and the collecting trough 27, when the crushing component 4 crushes the raw material, the suction component 26 can be driven, and then the suction component 26 will absorb the dust generated by the crushing, and then the dust will enter the interior of the collecting box 25, and the dust that enters the interior of the collecting box 25 statically will fall into the interior of the collecting trough 27, and when the dust needs to be cleaned, the collecting trough 27 can be pulled out from the interior of the collecting box 25, and then the dust inside it can be cleaned.

[0051] like Figure 1 and Figure 2 As shown, it also includes: a storage component, which is arranged at the bottom end of the crushing box 1, the storage component includes a storage groove 28, the storage groove 28 is arranged at the bottom end of the crushing box 1, and a roller 29 is arranged at the top of the storage groove 28. A square hole is opened on one side of the outer surface of the protective shell 13, and the rack 17 can move inside the square hole.

[0052] Through the design of the storage component, after the raw material is crushed, the swinging swing plate 15 will evenly guide the crushed raw material to the inside of the storage groove 28, and then the storage groove 28 can collect the raw material, and a roller 29 is provided at the bottom end of the storage groove 28, so as to facilitate the operator to transport the crushed raw material. Through the design of the protective shell 13 and the rack 17, when the rack 17 swings, it will enter the inside of the square hole, and the protective shell 13 will not interfere with the movement of the rack 17.

[0053] like Figure 3 and Figure 4 As shown, the guide plate 3 is designed to be inclined, the bottom end of the blocking plate 6 is designed to be inclined, and the bottom end of the blocking plate 6 is fully fitted with the bottom end inside the guide plate 3, the limit rod 5 is designed to be square, and the limit rod 5 is designed to be longitudinally symmetrical about the center of the blocking plate 6.

[0054] Through the design of the guide plate 3 and the blocking plate 6, since the guide plate 3 is designed to be inclined, it is convenient for the guide plate 3 to transfer the raw material to the inside of the guide ring 24, and the bottom end of the blocking plate 6 is in contact with the bottom end of the inside of the guide plate 3, thereby increasing the blocking effect of the blocking plate 6. Through the design of the limiting rod 5, when the blocking plate 6 moves, it moves on the surfaces of the two limiting rods 5, thereby increasing the limiting effect of the blocking plate 6, ensuring that the blocking plate 6 can move normally.

[0055] The working principle and use process of the present invention:

[0056] First, the operator can pour the raw material from the feed pipe 2 into the inside of the crushing box 1, and then the raw material will fall into the inside of the guide plate 3. When the raw material falls into the inside of the guide plate 3, the motor 8 can be driven to rotate the rotating disk 9 and the protrusion 11, and the protrusion 11 will push the push rod 10 and the protrusion 2 12 to swing back and forth. In the process of the swinging of the protective shell 13, the blocking plate 6 will be driven to move back and forth on the surface of the limit rod 5, so as to control the amount of raw material discharged. Then the inclined guide plate 3 will convey the raw material to the inside of the guide ring 24, and then the guide ring 24 will guide the raw material to the surface of the crushing component 4, and then the crushing component 4 can be driven to crush the raw material;

[0057] After the crushing is completed, the motor 2 18 can be driven to rotate the push rod 3 19 and the protrusion 3 20, and then the protrusion 3 20 will push the push rod 2 16 and the rack 17 to move back and forth, and the moving rack 17 will drive the gear 14 to rotate back and forth, and the gear 14 will drive the swing plate 15 to swing back and forth, and then the crushed raw materials will fall on the top of the swing plate 15, and through the swinging of the swing plate 15, the raw materials will be evenly guided to the inside of the storage groove 28. After the storage groove 28 completes the collection of the raw materials, the storage groove 28 can be pulled to rotate the roller 29, and then the roller 29 will drive the storage groove 28 and the raw materials to move to the next process, and finally complete the operation process.
