Description

Technical Field

[0001] This utility model belongs to the field of ceramic manufacturing technology, and in particular relates to a granulation machine for glazed tile body particles. Background Technology

[0002] In the ceramic manufacturing industry, glazed tiles, as a common building decoration material, involve several key steps in their production process. Among these, the preparation of the green body particles is one of the important factors affecting the quality of the final product. The uniformity, size, and shape of the glazed tile green body particles directly affect the density, strength, and surface quality of the fired product. However, traditional granulators still have the following problems during use: In the existing technology, powder is usually pressed into shape by a single extrusion roller. The distance between the extrusion rollers is not adjustable, which results in the uniformity of the thickness and density of the strip material. It is difficult to adapt to the characteristics of powder with different moisture content and particle size distribution. In particular, it has poor adaptability to high plastic clay or low flowability ceramic powder, and is prone to problems such as insufficient extrusion or excessive compaction. Screening devices are mostly static filters or vibrating screens with fixed apertures, which have low screening efficiency and cannot dynamically adjust the screen aperture size according to process requirements, making it difficult to meet users' needs for obtaining particles of different sizes. Utility Model Content

[0003] The purpose of this invention is to provide a granulator for glazed tile blanks. This granulator uses a double-threaded screw-driven extrusion wheel spacing adjustment mechanism to precisely control the meshing gap between the two extrusion wheels, achieving dynamic adaptation of the thickness and density of the strip-shaped powder. Simultaneously, it employs a double-crushing wheel structure linked by a synchronous wheel and synchronous belt, ensuring synchronous rotation of the two crushing wheels. Through the synergistic effect of uniform shearing and secondary crushing, particle uniformity is improved. Furthermore, through a through-hole overlap adjustment mechanism of a fixed arc plate and a moving arc plate, combined with a differential speed driven slider mechanism, continuous and precise control of the screening aperture can be achieved, effectively intercepting oversized particles and improving the consistency of the finished product. This equipment optimizes the granulation process, balancing high-efficiency production with convenient operation and maintenance, and solves existing technical problems.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A granulator for glazed tile body pellets, comprising: The support box is L-shaped and has a processing box fixedly installed on the top. The processing box has an extrusion chamber and a crushing chamber that are connected vertically inside.

[0005] Optionally, the extrusion assembly further includes a sealing bracket, the extrusion wheel is connected to a sliding block via a rotating shaft, the sliding block engages with the opposite thread section of a double-threaded screw, and the double-threaded screw drives the two extrusion wheels to move toward or away from each other when it rotates.

[0006] Optionally, one end of the rotating shaft is connected to a second motor, which is slidably mounted in the mounting cavity of the processing box via a bracket.

[0007] Optionally, the crushing assembly includes a connecting shaft and a synchronous pulley. The connecting shaft rotates through the processing box and connects to the crushing wheel. The two synchronous pulleys are connected by a synchronous belt and driven by a first motor.

[0008] Optionally, the drive screw is composed of a first screw, a connecting rod, and a second screw that are fixedly connected in sequence. The thread density of the first screw is greater than that of the second screw. The thread of the first screw passes through one side of the processing box.

[0011] Optionally, a hinged door is provided on one side of the processing box, and the hinged door communicates with the crushing chamber for cleaning and maintenance.

[0012] The embodiments of this utility model have the following beneficial effects: In this invention, the extrusion wheel spacing adjustment mechanism driven by the double-threaded screw can precisely control the meshing gap between the two extrusion wheels, enabling flexible adjustment of the thickness and density of the strip-shaped powder. This allows it to adapt to different raw material characteristics and process parameters, significantly improving the extrusion molding quality. In this utility model, by adopting a dual crushing wheel design with synchronous wheel and synchronous belt linkage, the two crushing wheels are ensured to rotate strictly synchronously, which can uniformly shear and secondary crush strip materials, effectively reduce uncrushed pieces and improve particle uniformity. In this invention, the fixed arc plate and the movable arc plate change the screening aperture by adjusting the overlap of the through holes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0025] Example 1: Please refer to Figure 1-6 As shown in the figure, this embodiment provides a granulator, which mainly includes a support box 1, a processing box 2, a feeding hopper 3, an extrusion assembly, a crushing assembly, a filtering assembly, and a discharge port 10.

[0026] In this embodiment, the support box 1 is L-shaped, and a processing box 2 is fixedly installed on its top. The processing box 2 has an extrusion chamber 7 and two crushing chambers 5 inside. The extrusion chamber 7 is located above the two crushing chambers 5, and the two crushing chambers 5 are connected and also communicate with the extrusion chamber 7. This structural design allows the powder to undergo extrusion and crushing processes sequentially within the processing box 2.

[0027] In this embodiment, the feeding hopper 3 is fixedly installed on the top of the processing box 2, and a valve 9 is provided at the bottom of the feeding hopper 3. When adding powder, the valve 9 is opened to add the powder into the processing box 2 through the feeding hopper 3. The valve 9 can control the powder flow rate to ensure that the powder falls evenly into the gap between the two extrusion rollers 8.

[0028] In this embodiment, the extrusion assembly is used to extrude powder into strips. The extrusion assembly includes two extrusion rollers 8 and an adjustment mechanism. Both extrusion rollers 8 are disposed within an extrusion chamber 7. A sealing bracket 14 is fixedly installed on the inner wall of the top of the extrusion chamber 7, and both extrusion rollers 8 slide in contact with the inner wall of the sealing bracket 14. The sealing bracket 14 engages with the bottom of the feeding hopper 3, which penetrates the inner wall of the top of the extrusion chamber 7, through a hole, ensuring that the powder can be accurately discharged between the two extrusion rollers 8. A rotating shaft 15 is fixedly inserted through the interior of each of the two extrusion rollers 8. Two sliding blocks 17 are slidably installed on one side of the processing box 2 via a slide groove. The other ends of the two rotating shafts 15 pass through another slide groove through one side of the extrusion chamber 7 and extend into the mounting cavity of the processing box 2. Two brackets are slidably installed on the inner wall of the mounting cavity of the processing box 2. A second motor 16 is fixedly installed on one side of each of the two brackets, and one end of the output shaft of each of the two second motors 16 is fixedly connected to one end of the corresponding rotating shaft 15. When the two second motors 16 are started, they drive the corresponding rotating shafts 15 to rotate, thereby driving the two extrusion rollers 8 to rotate. The two work together to complete the extrusion of powder into strips.

[0029] In this embodiment, the adjustment mechanism is used to adjust the distance between the two extrusion rollers 8. The adjustment mechanism includes a double-threaded screw 18 rotatably mounted on one side of the processing box 2 via a bracket. One side protrusion of each of the two sliding blocks 17 passes through a corresponding groove on one side of the processing box 2. The protrusions of the two sliding blocks 17 are threadedly connected to the double-threaded screw 18 and are respectively located on two opposite threaded sections of the double-threaded screw 18. When the double-threaded screw 18 is rotated, since the two sliding blocks 17 are threadedly connected to the two opposite threaded sections of the double-threaded screw 18, the two sliding blocks 17 will move towards or away from each other along the groove on one side of the processing box 2, thereby adjusting the distance between the two extrusion rollers 8 to adapt to different extrusion requirements.

[0030] In this embodiment, the crushing assembly is disposed within two crushing chambers 5 for crushing strip-shaped powder to produce powder particles. The crushing assembly includes two crushing wheels 6, which are respectively located within the two crushing chambers 5. The crushing assembly also includes two connecting shafts 11 that rotatably penetrate one side of the processing box 2. One end of each connecting shaft 11 is fixedly connected to the axis of the corresponding crushing wheel 6, and the other end of each connecting shaft 11 rotatably penetrates one side of the support box 1 and extends into the mounting cavity of the support box 1. Two synchronous pulleys 12 are disposed within the mounting cavity of the support box 1. The two synchronous pulleys 12 are respectively fixedly sleeved on the outer wall of the corresponding connecting shaft 11 and are connected by a synchronous belt drive. One end of one of the connecting shafts 11 is provided with a first motor 13, which is fixedly mounted in the mounting cavity of the support box 1 by a bracket. One end of the output shaft of the first motor 13 is fixedly connected to one end of the adjacent connecting shaft 11. When the first motor 13 starts, it drives one connecting shaft 11 to rotate. Through the transmission action of the synchronous pulley 12 and the synchronous belt, the other connecting shaft 11 rotates synchronously, thereby realizing the synchronous rotation of the two crushing wheels 6, and continuously crushing the strip-shaped powder and the powder fragments located in the crushing chamber 5.

[0031] In this embodiment, the filter assembly is used to block larger particles to ensure that the discharged particles meet the size requirements. The filter assembly includes a fixed arc-shaped plate 19 and a movable arc-shaped plate 20. An arc-shaped groove is provided at the bottom of the lowest crushing chamber 5. Both the fixed arc-shaped plate 19 and the movable arc-shaped plate 20 are located within the arc-shaped groove. The fixed arc-shaped plate 19 is located above the movable arc-shaped plate 20, and the fixed arc-shaped plate 19 is fixedly connected to the inner wall of the arc-shaped groove. The movable arc-shaped plate 20 is slidably engaged with the inner wall of the arc-shaped groove. Multiple through holes 21 are provided inside both the fixed arc-shaped plate 19 and the movable arc-shaped plate 20. The multiple through holes 21 in the fixed arc-shaped plate 19 and the multiple through holes 21 in the movable arc-shaped plate 20 cooperate with each other. When particles pass through the fixed arc-shaped plate 19 and the movable arc-shaped plate 20, particles that meet the size requirements can be discharged through the through holes 21, while larger particles are blocked.

[0032] In this embodiment, the filter assembly further includes an adjustment groove inside the processing box 2. A first slider 23 and a second slider 24 are slidably installed in the adjustment groove, with the second slider 24 fixedly installed on one side of the first slider 23. A limiting groove is provided on one side of the first slider 23, and a fixing post 22 is fixedly installed on one side of the movable arc plate 20. One end of the fixing post 22 passes through one side of the arc-shaped sliding groove through an arc-shaped sliding hole and extends into the adjustment groove. One end of the fixing post 22 is slidably engaged with the limiting groove in the first slider 23. A drive screw 25 is provided inside the adjustment groove for driving the second slider 24 and the first slider 23 to move horizontally. The drive screw 25 is composed of a first screw 26, a connecting rod 27, and a second screw 28, which are fixedly connected in sequence. The first screw 26 is threaded through one side of the processing box 2, and both the connecting rod 27 and the second screw 28 are slidably engaged with the processing box 2 through sliding holes. One end of the second screw 28 extends into the adjustment groove and is threadedly connected to the second slider 24. The thread density of the first screw 26 is greater than that of the second screw 28. When the drive screw 25 is rotated, due to the different thread densities of the first screw 26 and the second screw 28, the drive screw 25 can achieve precise drive adjustment of the second slider 24, thereby driving the first slider 23 to move, so as to realize the movement of the moving arc plate 20 in the arc groove. Ultimately, the degree of overlap of the through holes 21 on the fixed arc plate 19 and the moving arc plate 20 can be changed to adapt to the filtration requirements of particles of different sizes.

[0033] This application can be used in the field of ceramic manufacturing technology, or in other fields applicable to this application.

[0034] Example 2: Reference Figure 1 , 3 An improvement based on Example 1: a granulator for glazed tile body particles, which is applied to the field of ceramic manufacturing technology; In this embodiment, the support box 1 has an outlet 10 inside. The outlet 10 is located below the processing box 2 and is connected to the crushing chamber 5 through a through groove. The outlet 10 passes through one side of the support box 1. The filtered particles will be smoothly discharged through the outlet 10.

[0035] In this embodiment, a movable door 4 is hinged to one side of the processing box 2, and the movable door 4 cooperates with two crushing chambers 5. When it is necessary to clean and maintain the inside of the crushing chambers 5, the movable door 4 can be opened to facilitate operation inside the crushing chambers 5.

[0036] In this embodiment, four casters are fixedly installed at the bottom of the support box 1, which facilitates the movement of the equipment.

[0037] In this embodiment, a PLC controller is fixedly installed on the top of the support box 1 to complete the operation control of the equipment.

[0038] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 13 and the second motor 16 are commonplace and are conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0039] The usage process and working principle of this utility model technical solution are as follows: In operation, the powder to be processed is fed into the equipment through the feeding hopper 3, and the valve 9 is opened. The powder enters the extrusion chamber 7 through the bottom of the feeding hopper 3. The valve 9 controls the powder flow rate to ensure that the powder falls evenly into the gap between the two extrusion rollers 8.

[0040] At the same time, two corresponding second motors 16 are started, which drive the rotating shaft 15 to drive the two extrusion rollers 8 to rotate in opposite directions. The powder is pressed into a continuous strip structure under the meshing and extrusion action of the extrusion rollers 8.

[0041] During the extrusion of powder, the sliding block 17 can be driven by rotating the double threaded screw 18 to drive the extrusion wheel 8 to slide along the sealing bracket 14, thereby changing the distance between the two extrusion wheels 8 to control the thickness and density of the strip powder.

[0042] After being extruded, the strip-shaped powder falls from the extrusion chamber 7 into the crushing chamber 5 below. When the first motor 13 is started, it drives the two connecting shafts 11 to rotate the crushing wheel 6 synchronously through the transmission of the synchronous pulley 12 and the synchronous belt. This can shear the strip-shaped powder and continuously crush the powder fragments that enter the crushing chamber 5, turning them into granular materials.

[0043] The crushed particles fall to the bottom of the lowest crushing chamber 5 under the influence of gravity and the pushing force of the crushing wheel 6. Since the bottom of the crushing chamber 5 is equipped with a fixed arc-shaped plate 19 and a movable arc-shaped plate 20, the material particles are intercepted by these plates. Because both the fixed arc-shaped plate 19 and the movable arc-shaped plate 20 have through holes 21 inside, when the corresponding through holes 21 overlap, material particles of the appropriate size are discharged, while larger particles are blocked inside the crushing chamber 5 to continue crushing.

[0044] By rotating the drive screw 25, the user can achieve differential speed adjustment of the second slider 24 and the first slider 23 through a special design, thereby enabling precise horizontal movement. When the second slider 24 and the first slider 23 move, the fixed column 22 drives the movable arc plate 20 to slide relative to the fixed arc plate 19. At this time, the overlap of the through holes 21 of the fixed arc plate 19 and the movable arc plate 20 changes, thereby adjusting the screening aperture and further completing the particle screening. This ensures that particles that meet the size requirements pass through and fall into the discharge port 10, resulting in uniform and suitable particle size.

[0045] After using the equipment, users can open the movable door 4 to clean and maintain the inside of the crushing chamber 5 and the crushing wheel 6 to ensure the long-term stable operation of the equipment.
