[0024] The cylinder is rotatably connected to the middle of the left wall inside, and the shaft of the spiral rod is rotatably connected to the middle of the left end of the porous template.

[0025] A hopper is installed at the upper end of the control box, and the lower end of the hopper passes through the control box and communicates with the cylinder.
[0026] A method for preparing a toothed spherical alumina carrier includes the following steps:
[0027] The first step is material preparation. First, aluminum hydroxide, adhesive solvent, pore expander and molding aid are added to the mixer and mixed. Then, deionized water and nitric acid are added to the mixer and mixed again to obtain a soft block plastic body.
[0028] The second step is material preparation. Soft block-shaped plastic body is put into the hopper and enters the cylinder through the hopper. Then, the second driving device is used to drive the screw to rotate in the cylinder. The rotating screw stirs and pushes the soft block-shaped plastic body in the cylinder. Multiple toothed strips of material are extruded through the multi-hole template and multiple toothed modules.
[0029] The third step is traction. The extruded toothed strips of material are guided into the lower end of the spreading wheel. The spreading wheel restricts the toothed strips of material to be laid flat on the same plane. Then, the cylindrical column lifts the restricted and laid toothed strips of material. At the same time, multiple cylindrical rods separate the toothed strips of material. The separated toothed strips of material are then guided onto multiple annular grooves on the traction wheel. Meanwhile, the first drive device drives the traction wheel to rotate, and the rotating traction wheel tractions the toothed strips of material in an orderly manner.
[0030] The fourth step is cutting. Multiple baffles separate the toothed strips of material that have been pulled out. At the same time, the rotation of the traction wheel causes the first gear to rotate, and the second gear to rotate under the transmission of the synchronous belt, which in turn causes the I-shaped wheel to rotate, thereby causing multiple molybdenum wires to rotate. Meanwhile, the telescopic device drives the I-shaped wheel to move back and forth in a circular motion, which in turn causes multiple molybdenum wires to move back and forth in a circular motion. The molybdenum wires moving back and forth in a circular motion synchronously cut the multiple toothed strips of material to obtain toothed small segments of material.
[0031] The fifth step is shaping. The toothed segments are fed into a disc granulator and shaped to produce toothed spherical material.
[0032] The beneficial effects of this invention are:
[0033] 1. The toothed spherical alumina carrier preparation equipment of the present invention realizes the synchronous extrusion molding of multiple toothed strip materials through a porous template and multiple toothed modules. The multiple toothed strip materials are synchronously pulled by a rotating traction wheel, and then the I-shaped wheel and multiple molybdenum wires are rotated. At the same time, the I-shaped wheel and molybdenum wires are moved back and forth in a circular motion by an electric push rod. Through the rotation and back and forth circular motion of the molybdenum wires, the multiple toothed strip materials can be synchronously cut into toothed small segments, which effectively avoids the damage to the toothed shape of the material caused by balling and improves the product quality.
[0034] 2. The toothed spherical alumina carrier preparation equipment of the present invention, if the toothed strip material has a hole in the middle, a gap is created between the baffle and the rightmost molybdenum wire through the screw, so as to retain the hole in the toothed strip material and cut the toothed strip material into a perforated Raschig ring. In addition, the distance between the baffle and the rightmost molybdenum wire can be adjusted according to the diameter of the hole, so as to meet the cutting of toothed strip materials with holes of different diameters, which has good practicality.
[0035] 3. The toothed spherical alumina carrier preparation equipment of the present invention uses a flat-laying wheel, a cylinder and multiple round rods to separate multiple toothed strip materials, ensuring that the multiple toothed strip materials are laid flat. Then, multiple annular grooves on the traction wheel are used to realize the synchronous traction of multiple toothed strip materials, ensuring the subsequent extrusion molding operation of multiple toothed strip materials, and the working effect is good.
[0036] 4. The toothed spherical alumina carrier preparation equipment of the present invention utilizes multiple partitions to separate multiple toothed strips of material being pulled, effectively avoiding the cross-linking phenomenon among the multiple toothed strips of material being pulled, ensuring normal cutting of the multiple toothed strips of material in the subsequent process, and improving the cutting effect.
[0037] 5. The toothed spherical alumina carrier preparation equipment of the present invention has molybdenum wires at both ends fixed to the front and rear ends of the I-shaped wheel by bolts. On the one hand, it facilitates the easy installation and removal of molybdenum wires and realizes multiple molybdenum wires arranged in a circular pattern at equal intervals on the outer end of the I-shaped wheel. On the other hand, it allows adjustment of the number of molybdenum wires installed on the I-shaped wheel to manufacture toothed spheres of different diameters. It has good practicality. The groove restricts the installation between the molybdenum wires and the I-shaped wheel, effectively avoiding the probability of molybdenum wire displacement and ensuring cutting quality.
[0038] 6. The toothed spherical alumina carrier preparation equipment of the present invention uses a first screen to block and filter large-sized toothed small segments of material, and a second screen to block and filter qualified toothed small segments of material, thereby achieving sorting of the generated toothed small segments of material, ensuring the quality of subsequent granulation, and having good functionality.

[0052] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0053] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention provides a technical solution: a toothed spherical alumina carrier preparation device, including a base plate 1, and four supporting columns 13 respectively set at the four corner positions of the lower end of the base plate 1, so as to support the base plate 1 through the four supporting columns 13;
[0054] The control box 2 is placed on the upper left side of the base plate 1, and the cylinder 4 extending into the control box 2 is placed on the upper right side of the control box 2. The hopper 21, whose lower end passes through the control box 2 and is connected to the cylinder 4, is placed on the upper end of the control box 2. Materials are fed into the cylinder 4 through the hopper 21.
[0055] The spiral rod 42, which is rotatably connected to the middle of the left end of the porous template 3, is rotatably connected to the middle of the left wall inside the cylinder 4. The fixed part of the second drive device, which passes through the control box 2 and the cylinder 4 and is connected to the spiral rod 42, is set on the left end of the control box 2. The spiral rod 42 is driven to rotate inside the cylinder 4 by the second drive device to realize the stirring and pushing operation.
[0056] The perforated template 3 is installed on the right end of the cylinder 4, and multiple toothed modules 5 arranged in a circular pattern and connected to the outlet holes of the perforated template 3 are equidistantly placed on the right end of the perforated template 3. The perforated template 3 and the multiple toothed modules 5 are used together to form multiple toothed strips of material.
[0057] In use, materials are first fed into the hopper 21 and transported into the cylinder 4 through the hopper 21. At the same time, the second drive device is started, which drives the screw rod 42 to rotate, thereby stirring and pushing the material in the cylinder 4 to the right. When the material comes into contact with the left end of the porous template 3, the stirring screw rod 42 will apply extrusion pressure to the material and extrude the material through multiple holes on the porous template 3. At the same time, the extruded material passes through the toothed module 5, realizing the synchronous extrusion forming of multiple toothed strips of material. The second drive device can be the first motor 41.
[0058] Example 2: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the fixing plate 6, which is located on the right rear side of the control box 2 and on the rear side of the perforated template 3, is set on the upper rear edge of the bottom plate 1. The fixing plate 6 provides an installation carrier for components such as the traction wheel 7.
[0059] To address the issue that the multiple toothed strips of material extruded using the porous template 3 and multiple toothed modules 5 are generally arranged in a circular structure, which makes them difficult to be effectively pulled out and causes the produced toothed strips to stop, thus hindering the extrusion molding operation, the flat-laying wheel 61 located on the upper left side of the cylinder 63 and the lower right side of the porous template 3 is set on the front end of the fixed plate 6, and the cylinder 63 located on the upper left side of the traction wheel 7 is installed on the front end of the fixed plate 6. Then, multiple vertically arranged round rods 62 are equidistantly set on the upper end of the cylinder 63.
[0060] The shaft of the traction wheel 7 is rotatably connected to the front end of the fixed plate 6. Multiple annular grooves 73 are formed inwardly recessed on the annular end face of the traction wheel 7, and the fixed part of the first drive device, which connects the movable part to the shaft of the traction wheel 7, is set on the rear end of the fixed plate 6.
[0061] When using the porous template 3 and multiple toothed modules 5, multiple toothed strips of material are extruded and formed. These toothed strips are then laid flat on the lower end of the spreading wheel 61, and then placed on the upper end of the cylinder 63. Multiple round rods 62 separate the toothed strips to ensure they are laid flat. The toothed strips are then wound one by one onto the corresponding annular grooves 73 on the traction wheel 7. At the same time, the first drive device is started, which drives the traction wheel 7 to rotate. This causes the multiple annular grooves 73 to rotate synchronously, achieving synchronous traction of the toothed strips. This ensures good extrusion and forming results for the subsequent toothed strips. The first drive device can be a second motor 74.
[0062] Example 3: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the shaft of the I-shaped wheel 9 located directly below the traction wheel 7 is movably connected to the front end of the fixed plate 6, and the first gear 72 installed on the outer end of the shaft of the traction wheel 7 and the second gear 91 located directly below the first gear 72 and installed on the outer end of the shaft of the I-shaped wheel 9 are respectively meshed on the upper and lower walls inside the synchronous belt 71 located on the front side of the fixed plate 6.
[0063] The fixed part of the telescopic device located below the first driving device is set on the rear end of the fixed plate 6. The movable part of the telescopic device is connected to the shaft of the I-shaped wheel 9. A plurality of slide bars 92 arranged in a circle and located on the front side of the fixed plate 6 are equidistantly set on the outer end of the shaft of the I-shaped wheel 9. A plurality of slide grooves that slide in a sliding connection with the slide bars 92 are formed by recessing outward on the inner wall of the second gear 91. The telescopic device drives the I-shaped wheel 9 to move back and forth in a cyclic manner. The telescopic device can be an electric push rod 75.
[0064] One end of the molybdenum wire 8 is fixed to the front end of the I-shaped wheel 9 with a bolt, and the other end of the molybdenum wire 8 is fixed to the rear end of the I-shaped wheel 9 with a screw. This makes it easy to install and remove the molybdenum wire 8 and allows multiple molybdenum wires 8 to be arranged in a circular pattern at equal intervals on the outer end of the I-shaped wheel 9. On the other hand, it allows for adjustment of the number of molybdenum wires 8 installed on the I-shaped wheel 9 to manufacture toothed balls of different diameters, which is very practical.
[0065] An L-shaped plate 643 is placed at the front end of a fixed plate 6, and a baffle 64 on the left side of the L-shaped plate 643 is attached to the molybdenum wire 8 on the right. A screw 641, which is rotatably connected to the middle of the right end of the baffle 64 and passes through the L-shaped plate 643, is threaded to the L-shaped plate 643. The distance between the baffle 64 and the molybdenum wire 8 on the right is adjusted by the screw 641. Four smooth rods 642 located outside the screw 641 are respectively placed at the four corners of the right end of the baffle 64. The four smooth rods 642 that pass through the L-shaped plate 643 are slidably connected to the L-shaped plate 643. The movement of the baffle 64 is guided by the smooth rods 642.
[0066] First, the traction wheel 7 is rotated to synchronously traction multiple toothed materials, and at the same time, the multiple toothed materials move down along the baffle 64 and enter between the I-shaped wheel 9 and the baffle 64. Meanwhile, the rotation of the traction wheel 7 will cause the first gear 72 to rotate, and under the transmission of the synchronous belt 71, the second gear 91 will rotate. With the cooperation of the slide bar 92 and the slide groove, the I-shaped wheel 9 will rotate, thereby causing multiple molybdenum wires 8 to rotate.
[0067] Simultaneously, the telescopic device is activated, which drives the I-shaped wheel 9 to move back and forth in a cyclical manner, thereby causing the molybdenum wire 8 to move back and forth in a cyclical manner. When the toothed material enters between the I-shaped wheel 9 and the baffle 64, the molybdenum wire 8, which moves back and forth in a cyclical manner, will simultaneously cut multiple toothed materials. Through the rotation and back and forth cyclical movement of the molybdenum wire 8, multiple toothed materials can be simultaneously cut and formed into toothed small segments, effectively avoiding the damage to the toothed shape of the material caused by balling and improving product quality.
[0068] Before operation, if the toothed material has a hole in the middle, the screw 641 can be rotated. Since the screw 641 is threadedly connected to the L-shaped plate 643, the rotation of the screw 641 causes it to move linearly, which in turn causes the baffle 64 to move left and right, creating a gap between the baffle 64 and the rightmost molybdenum wire 8. This gap is used to retain the hole in the toothed material and cut it into a perforated Raschig ring. In addition, the distance between the baffle 64 and the rightmost molybdenum wire 8 can be adjusted by the screw 641 according to the diameter of the hole, which can meet the needs of cutting toothed materials with holes of different diameters, making it highly practical.
[0069] Example 4: Figure 1 , Figure 3 and Figure 9 As shown, in order to solve the problem that when multiple toothed strips are pulled by multiple annular grooves 73 on the I-shaped wheel 9, the toothed strips pulled from the annular grooves 73 will move down into the space between the I-shaped wheel 9 and the baffle 64, but the multiple toothed strips moving down are prone to interlacing, which makes it impossible to effectively cut the interlaced toothed strips and affects the subsequent cutting effect;
[0070] Multiple partitions 65, located between the I-shaped wheel 9 and the traction wheel 7 and arranged laterally, are equidistantly placed on the left end of the baffle 64, and an annular groove 73 is provided between two adjacent partitions 65.
[0071] When multiple toothed strip materials are synchronously pulled by the traction wheel 7, the toothed strip materials can pass through the space between two adjacent partitions 65 and move downwards. At this time, multiple partitions 65 are used to separate the pulled toothed strip materials, effectively avoiding the crossover phenomenon among the pulled toothed strip materials, ensuring the normal cutting of the multiple toothed strip materials in the future, and improving the cutting effect.
[0072] Example 5: Figure 6 , Figure 7 and Figure 8 As shown, in order to solve the problem of using multiple molybdenum wires 8 for cutting, the multiple molybdenum wires 8 are equidistantly arranged on the outer end of the I-shaped wheel 9. During the rotation of the I-shaped wheel 9 and the cutting process of the multiple molybdenum wires 8, a force is generated on the position of the molybdenum wires 8 located between the two cams of the I-shaped wheel 9. Under the action of the force, the molybdenum wires 8 are prone to displacement, resulting in dimensional errors of the material being cut in subsequent cutting operations, thus affecting the cutting quality.
[0073] Multiple grooves 93 are formed by recessing the outer end faces of the two cam sections of the I-shaped wheel 9 inward. When installing the molybdenum wire 8, the two ends of the molybdenum wire 8 are respectively installed to the front and rear ends of the I-shaped wheel 9 by bolts, and the inward end of the molybdenum wire 8 is inserted into the groove 93, so that the molybdenum wire 8 and the I-shaped wheel 9 are restricted in installation, effectively avoiding the probability of displacement of the molybdenum wire 8 and ensuring the cutting quality.
[0074] Example 6: Figure 1 , Figure 2 , Figure 3 , Figure 10 and Figure 11 As shown, the mounting box 11, which is located on the lower side of the porous template 3 and at the front end of the fixing plate 6, is installed on the upper end of the base plate 1, and the power supply is installed in the mounting box 11 to provide power to the first drive device and other components.
[0075] To address the issue that when multiple molybdenum wires 8 are used to cut toothed segments, the molybdenum wires 8 tend to exert tensile force on the cut position of the toothed strip material during cutting, causing deformation at the cut position and altering the size of the toothed segments produced after subsequent cutting, thus affecting subsequent granulation;
[0076] A conical box 12, which extends from the right side of the base plate 1 and is wider on the left and narrower on the right, and is located directly below the I-shaped wheel 9, is placed on the right end of the mounting box 11. An opening communicating with the inner cavity of the conical box 12 is formed by a downward indentation on the upper slope of the conical box 12. A first screen 14, which is inclined from left to right, is placed in the opening. A guide plate 16, which is inclined from left to right, is placed on the upper edge of the right end of the conical box 12. The upper end face of the guide plate 16 and the upper end face of the first screen 14 coincide with the inclined surface of the upper end of the conical box 12.
[0077] A first outlet 15 is formed by a left-facing recess at the right end of the conical box 12, which communicates with the inner cavity of the conical box 12 and is located below the guide plate 16. A second screen 17, whose right end is connected to the first outlet 15 and is arranged in an inclined manner with the left side higher than the right side, is installed inside the conical box 12.
[0078] A second outlet 18 is formed by recessing the lower end of the conical box 12 upwards, communicating with the inner cavity of the conical box 12 and located on the right side of the bottom plate 1. A conical cover 19, located below the second screen 17 and with its lower end communicating with the second outlet 18 and arranged in a wide-at-the-top and narrow-at-the-bottom configuration, is installed on the bottom of the conical box 12.
[0079] The toothed segments of material produced by cutting with multiple molybdenum wires 8 fall onto the first screen 14. The first screen 14 blocks and filters the large toothed segments. The large toothed segments are then discharged along the first screen 14 and the guide plate 16, while the qualified or smaller toothed segments pass through the first screen 14 and fall onto the second screen 17. The second screen 17 blocks and filters the qualified toothed segments.
[0080] Then, the qualified toothed segments roll on the second screen 17 and are discharged through the first outlet 15, while the small toothed segments will pass through the second screen 17 and fall into the conical shroud 19, and then be discharged through the second outlet 18. This process sorts the generated toothed segments, ensuring the quality of subsequent granulation and providing good functionality.
[0081] A method for preparing a toothed spherical alumina carrier includes the following steps:
[0082] The first step is material preparation. First, aluminum hydroxide, adhesive solvent, pore expander and molding aid are added to the mixer and mixed. Then, deionized water and nitric acid are added to the mixer and mixed again to obtain a soft block plastic body.
[0083] The second step is material preparation. The soft block-shaped plastic body is put into the hopper 21 and enters the cylinder 4 through the hopper 21. Then, the second driving device is used to drive the screw rod 42 to rotate inside the cylinder 4. The rotating screw rod 42 is used to stir and push the soft block-shaped plastic body inside the cylinder 4. Multiple toothed strips of material are extruded through the porous template 3 and multiple toothed modules 5.
[0084] The third step is traction. The extruded toothed strips of material are guided into the lower end of the spreading wheel 61. The spreading wheel 61 restricts the toothed strips of material to be spread flat on the same plane. The cylinder 63 then lifts the restricted and spread toothed strips of material. At the same time, the multiple round rods 62 separate the toothed strips of material. The separated toothed strips of material are then guided onto the multiple annular grooves 73 on the traction wheel 7. Meanwhile, the first driving device drives the traction wheel 7 to rotate, and the rotating traction wheel 7 tractions the toothed strips of material in an orderly manner.
[0085] The fourth step is cutting. Multiple baffles 65 separate the toothed strips of material that have been pulled out. At the same time, the rotation of the traction wheel 7 causes the first gear 72 to rotate, and the second gear 91 to rotate under the transmission of the synchronous belt 71, which in turn causes the I-shaped wheel 9 to rotate, thereby causing multiple molybdenum wires 8 to rotate. At the same time, the telescopic device drives the I-shaped wheel 9 to move back and forth in a circular motion, thereby causing multiple molybdenum wires 8 to move back and forth in a circular motion. The molybdenum wires 8 moving back and forth in a circular motion synchronously cut the multiple toothed strips of material to obtain toothed small segments of material.
[0086] The fifth step is shaping. The toothed segments are fed into a disc granulator and shaped to produce toothed spherical material.
