Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, specifically a universal grinding machine for ceramic roller processing. Background Technology

[0002] As is generally known, ceramic rollers are refractory products made from refractory clay and natural mineral raw materials through processes such as selection, crushing, processing, mixing, shaping, and calcination. Ceramic rollers are core components of roller kilns, primarily used to support and transport ceramic, glass, and other products within high-temperature kilns. Their main purpose is as a transport and support component in kilns, widely applied in the firing processes of industries such as ceramics, building materials, and metallurgy. Their core function is to achieve stable transport and uniform heating of ceramic products (such as polished tiles, glazed tiles, and roof tiles) within the kiln through their high-temperature resistance, thermal shock resistance, and low deformation characteristics. They are particularly suitable for ultra-wide kilns and heavy-load, high-volume production environments.

[0003] The production process of ceramic rollers is as follows: 1. Raw material processing: High-purity alumina powder (purity ≥95%), titanium dioxide, and additives such as yttrium oxide are ground into particles that can pass through a 200-mesh sieve using a ball mill; 2. Extrusion molding: The ground slurry is vacuum-processed, and then the processed raw material is extruded into ceramic roller blanks using an extruder and a specific mold; 3. Drying treatment: The formed ceramic roller blanks are first air-dried, and then transported to a drying kiln for drying treatment to obtain dried ceramic roller blanks; 4. High-temperature sintering: The dried ceramic roller blanks are placed in a high-temperature kiln to fully sinter and form a dense crystalline structure. After sintering, they are cooled with the furnace to obtain sintered ceramic rollers; 5. Processing and inspection: The sintered ceramic rollers are ground using a grinding machine, and then the dimensions, hardness, and strength of the ground ceramic rollers are tested to obtain qualified ceramic rollers.

[0004] For example, the patent entitled "A Polishing Device for Repairing the Surface of Silicon Carbide Ceramic Rollers" published on August 16, 2024, with announcement number CN118372104B, relates to the field of polishing equipment technology, and in particular to a polishing device for repairing the surface of silicon carbide ceramic rollers. It includes a housing, a frame connected to the lower part of the outer wall of the housing, annular inlet and outlet channels connected to both side walls of the housing, a clamping and conveying mechanism provided on the annular inlet and outlet channels, and a polishing mechanism provided inside the housing. By hinged three grinding plates to three sliding rods and using spring II to allow the three grinding plates to contact each other and adhere to the end face of the silicon carbide ceramic roller, the end face of the silicon carbide ceramic roller is polished. Furthermore, moving the silicon carbide ceramic roller to the right causes the three grinding plates to rotate and separate, so that the grinding plates are parallel to the central axis of the silicon carbide ceramic roller and adhere to the circumferential side of the roller, achieving polishing of the circumferential side of the silicon carbide ceramic roller without any polishing dead angles. This improves the polishing effect and quality of the silicon carbide ceramic roller, thereby enhancing its overall quality.

[0005] As shown in the aforementioned patent, the shortcomings of the prior art are that when grinding ceramic rollers, the ceramic rollers need to be axially conveyed, and then the ceramic rollers are ground by circumferentially rotating grinding discs. When conveying the ceramic rollers axially, the ceramic rollers also need to be aligned with the circumferentially set grinding discs. Furthermore, due to the long length of the ceramic rollers, the conveying distance of the ceramic rollers is long, and deflection (i.e., the axis shifts) is prone to occur when the ceramic rollers are conveyed and ground, resulting in uneven grinding of the ceramic roller surface. Summary of the Invention

[0006] The purpose of this invention is to provide a universal grinding machine for processing ceramic rollers, thereby solving the technical problems in related technologies.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a universal grinding machine for processing ceramic rollers, comprising a frame and a conveying mechanism. The frame is provided with a conveying mechanism for conveying the ceramic roller body, and also includes a grinding unit. The grinding unit includes a grinding disc. Two bearing rollers capable of driving the ceramic roller body to rotate are symmetrically installed at both ends of the frame. A grinding disc capable of linear reciprocating along the axial direction of the bearing rollers is provided in the middle of the frame. The reciprocating grinding disc performs grinding operations on the circumferentially rotating ceramic roller body.

[0008] As described above, a square groove is provided in the middle of the frame, and a first synchronous wheel is rotatably installed at each end of the square groove. The two first synchronous wheels are connected by a first synchronous belt. A driven plate is slidably installed on the frame, and the grinding disc is disposed at the top of the driven plate. The first synchronous belt is connected to the driven plate.

[0009] As described above, a first driving component is provided in the square groove, and the output end of the first driving component is connected to one of the first synchronous pulleys.

[0010] As described above, two flat grooves are symmetrically opened on the driven plate, and a retaining plate is slidably installed in each of the two flat grooves. A grinding disc is provided on each of the two retaining plates.

[0011] As described above, two flat plates are symmetrically installed on both sides of the abutment plate on the inner walls of the two flat grooves, and the bottom ends of the two flat plates are wedge-shaped.

[0012] As mentioned above, each of the two flat plates is rotatably mounted with an adhesive roller.

[0013] As described above, each of the two abutting plates has a push plate installed at its bottom end, and the two push plates and their corresponding flat grooves are connected by a second driving member.

[0014] As described above, each of the two propulsion plates has an inverted trapezoidal groove, and the two trapezoidal grooves are respectively configured to wedge with the wedge-shaped surfaces on their corresponding flat plates.

[0015] As described above, the two flat plates and their corresponding inner walls of the grooves are each connected by a first elastic element.

[0016] As described above, a vacuum cleaner is provided on the side wall of the driven plate, and the suction end of the vacuum cleaner is connected to the flat groove.

[0017] The beneficial effects of this invention are as follows: When it is necessary to perform grinding and polishing operations on the ceramic roller body, the operator places the ceramic roller body between two carrier rollers through the conveying mechanism. The two carrier rollers drive the ceramic roller body to rotate, and the reciprocating grinding discs simultaneously grind the rotating ceramic roller body. This allows the grinding discs to perform comprehensive grinding operations on the rotating ceramic roller body without causing the ceramic roller body to deflect during grinding. Furthermore, the mutual contact between the reciprocating grinding discs and the rotating ceramic roller body during grinding makes the grinding of the ceramic roller body more uniform.

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 To be continued Figure 11 The present invention will now be described in further detail.

[0022] An embodiment of the present invention relates to a universal grinding machine for processing ceramic rollers, comprising a frame 1 and a conveying mechanism. The frame 1 is provided with a conveying mechanism for conveying the ceramic roller body 3. The invention is characterized by further including a grinding unit, which includes a grinding disc 2. Two bearing rollers 4 capable of driving the ceramic roller body 3 to rotate are symmetrically installed at both ends of the frame 1. A grinding disc 2 capable of linear reciprocating along the axial direction of the bearing rollers 4 is provided in the middle of the frame 1. The reciprocating grinding disc 2 performs grinding operations on the circumferentially rotating ceramic roller body 3.

[0023] Specifically, the ceramic roller body 3 is a slender cylindrical structure. The ceramic roller body 3 is the core component of the roller kiln, mainly used to support and transport ceramic, glass, and other products within the high-temperature kiln. The frame 1 is the base for mounting various components. The frame 1 is equipped with a conveying mechanism (not shown in the figure) for transporting the ceramic roller body 3. This conveying mechanism transports the ceramic roller body 3 to the section between two carrier rollers 4. The conveying mechanism's function of transporting the ceramic roller body 3 is common knowledge in the field and will not be elaborated upon. Two carrier rollers 4, capable of driving the ceramic roller body 3 to rotate, are symmetrically installed at both ends of the frame 1. A power component 53 is installed at the end of each carrier roller 4. When the carrier roller 4 needs to drive the ceramic roller body 3 to rotate, the power component 53 (a device with an output end capable of forward and reverse rotation, preferably a motor) is activated to drive the carrier roller 4 to rotate, thus causing the carrier roller 4 to drive the ceramic roller body 3 to rotate. The frame 1 has a square groove 5 in the middle, and a first synchronous wheel 6 is rotatably installed at each end of the square groove 5. The two first synchronous wheels 6 are connected by a first synchronous belt 7. A driven plate 8 is slidably installed on the frame 1, and the first synchronous belt 7 is connected to the driven plate 8. A first driving member 9 is provided in the square groove 5, and the output end of the first driving member 9 is connected to one of the first synchronous wheels 6. Two flat grooves 10 are symmetrically opened on the driven plate 8. A pressing plate 11 is slidably installed in each of the two flat grooves 10. A grinding disc 2 is provided on each of the two pressing plates 11. The grinding disc 2 has an arc-shaped structure, and the arc-shaped concave surface of the grinding disc 2 is pressed against the outer wall of the ceramic roller body 3 for grinding. A push plate 12 is installed at the bottom end of each of the two pressing plates 11. The two push plates 12 and their corresponding flat grooves 10 are connected by a second driving member 13.After the conveying mechanism transports the ceramic roller body 3 to the section between the two bearing rollers 4, the first drive component 9 (the first drive component 9 is a device with an output end capable of forward and reverse rotation, preferably a motor) is activated to drive the first synchronous pulley 6 to rotate. Since the two first synchronous pulleys 6 are connected by the first synchronous belt 7, the two first synchronous pulleys 6 drive the first synchronous belt 7 to move. The first synchronous belt 7 drives the driven plate 8 to slide on the frame 1. The first drive component 9 drives the first synchronous pulley 6 to rotate back and forth, so that the first synchronous belt 7 can drive the driven plate 8 to perform linear reciprocating motion on the frame 1. Simultaneously, the second drive component 13 (the second drive component 13 is a device with an output end capable of linear reciprocating motion, preferably a hydraulic cylinder) is activated to drive the push... The feed plate 12 and the clamping plate 11 move upwards (i.e., towards the end closer to the ceramic roller body 3). The clamping plate 11 drives the grinding disc 2 to press against the outer wall of the ceramic roller body 3. Simultaneously, the two bearing rollers 4 drive the ceramic roller body 3 to rotate, allowing the linearly reciprocating grinding disc 2 to perform circumferential and axial grinding operations on the outer wall of the rotating ceramic roller body 3. Furthermore, the two bearing rollers 4 position the ends of the ceramic roller body 3, and the grinding disc 2 limits the middle of the ceramic roller body 3, preventing the ceramic roller body 3 from deflecting during grinding. Through the mutual pressing and grinding between the reciprocating grinding disc 2 and the rotating ceramic roller body 3, the ceramic roller body 3 is ground more evenly.

[0024] The shortcomings of the existing technology are that when grinding ceramic rollers, the ceramic rollers need to be axially conveyed, and then the ceramic rollers are ground by the circumferentially rotating grinding discs 2. When conveying the ceramic rollers axially, the ceramic rollers also need to be aligned with the circumferentially set grinding discs 2. Furthermore, due to the long length of the ceramic rollers, the conveying distance of the ceramic rollers is long, and the ceramic rollers are prone to deflection (i.e., the axis shifts) during conveying and grinding, resulting in uneven grinding of the ceramic roller surface.

[0025] The beneficial effects of this embodiment are as follows: When it is necessary to perform grinding and polishing operations on the ceramic roller body 3, the operator places the ceramic roller body 3 between the two carrier rollers 4 through the conveying mechanism. The two carrier rollers 4 drive the ceramic roller body 3 to rotate, and the reciprocating grinding disc 2 simultaneously grinds the rotating ceramic roller body 3. This allows the grinding disc 2 to perform comprehensive grinding operations on the rotating ceramic roller body 3, preventing the ceramic roller body 3 from deflecting during grinding. Furthermore, the mutual contact between the reciprocating grinding disc 2 and the rotating ceramic roller body 3 during grinding makes the grinding of the ceramic roller body 3 more uniform.

[0026] In another embodiment of the present invention, two flat plates 14 are symmetrically installed on the inner walls of the two flat grooves 10 on both sides of the abutment plate 11, and the bottom ends of the two flat plates 14 are wedge-shaped surfaces; an adhesive roller 15 is rotatably installed on each of the two flat plates 14; an inverted trapezoidal groove 16 is opened on each of the two push plates 12, and the two trapezoidal grooves 16 are respectively wedge-shapedly engaged with the wedge-shaped surfaces on their corresponding flat plates 14; the two flat plates 14 and the inner walls of their corresponding flat grooves 10 are connected by a first elastic member 17; a vacuum cleaner 18 is provided on the side wall of the driven plate 8, and the suction end of the vacuum cleaner 18 is connected to the flat groove 10.

[0027] Specifically, during the process where the second driving member 13 drives the grinding disc 2 to press against the outer wall of the ceramic roller body 3 via the push plate 12 and the abutting plate 11, the push plate 12 has an inverted trapezoidal groove 16, and the trapezoidal groove 16 and the wedge-shaped surface on the plate 14 are wedge-shaped and engaged with each other, so that as the push plate 12 moves upward, it pushes the plate 14 towards one end through the trapezoidal groove 16 (that is, the push plate 12 pushes the plate 14 towards the end closer to the ceramic roller body 3). This ensures that the grinding disc 2 presses against the outer wall of the ceramic roller body 3. When the ceramic roller body 3 is polished, the plate 14 drives the adhesion roller 15 to press against the outer wall of the ceramic roller body 3. The adhesion roller 15 has a certain degree of adhesion and elasticity. When the polishing disc 2 polishes the ceramic roller body 3, there are polishing debris on the polishing disc 2 and the ceramic roller body 3. In the direction of circumferential rotation of the ceramic roller body 3, the two adhesion rollers 15 are driven to rotate by the ceramic roller body 3, so that the adhesion rollers 15 can adhere and absorb the residual polishing debris on the ceramic roller body 3. Simultaneously, the plate 14 presses against the first elastic element 17 (the first elastic element 17 is capable of...). The first elastic element 17 is stretched to achieve the retraction and reset function. Simultaneously, the vacuum cleaner 18 is activated (the vacuum cleaner 18 uses a motor to drive the blades to rotate at high speed, generating negative air pressure in the sealed housing to suck up dust; this is common knowledge in the art and will not be elaborated upon). This causes the vacuum cleaner 18 to generate suction force in the flat groove 10, enabling it to completely absorb the grinding debris and prevent it from affecting the grinding of the ceramic roller body 3. Preferably, a scraper 19 is provided on the flat plate 14, and the scraper 19 adheres to the surface. The outer walls of the rollers 15 are pressed together, allowing the scraper 19 to scrape off the grinding debris adhering to the outer wall of the adhesive rollers 15. After the scraper 19 removes the grinding debris from the adhesive rollers 15, the scraped-off grinding debris is absorbed by the vacuum cleaner 18, reducing the impact of the grinding debris on the grinding of the ceramic roller body 3 and further improving the uniformity of the grinding of the ceramic roller body 3. Preferably, the position of the adhesive rollers 15 is elastic, that is, a fifth elastic element 20 is provided on the flat plate 14, and a clamping plate 21 is connected to the fifth elastic element 20. The adhesive rollers 15 are rotatably mounted on the clamping plate 21. Figure 7As shown, when the adhesive roller 15 presses against the ceramic roller body 3, the ceramic roller body 3 squeezes the adhesive roller 15 and the clamping plate 21, causing the fifth elastic element 20 (the fifth elastic element 20 is an element that can extend and retract, preferably a spring) to be in a compressed state. The fifth elastic element can provide elastic force to the clamping plate 21 and the adhesive roller 15. Under the action of the elastic force of the adhesive roller 15 itself, the adhesive roller 15 can press against the ceramic roller body 3 under the action of elastic force, so that the adhesive roller 15 can perform a comprehensive adhesion operation on the grinding debris remaining on the ceramic roller body 3, reduce the impact of grinding debris on the grinding of the ceramic roller body 3, and further improve the uniformity of grinding of the ceramic roller body 3.

[0028] In another embodiment of the present invention, two bearing units are symmetrically installed at both ends of the frame 1. In order to improve the grinding efficiency of the ceramic rod body, the two bearing units are used as the same grinding structure in this embodiment. The bearing unit includes a straight rod 22. A groove 23 is provided on the frame 1. The straight rod 22 is slidably installed in the middle of the groove 23. A support roller 24 is rotatably installed on the top of the straight rod 22. Two swing rods 26 are rotatably installed at both ends of the groove 23 through a positioning shaft 25. A second elastic element 27 is connected between each swing rod 26 and the inner wall of the groove 23. The tops of the two swing rods 26 on the same grinding structure, which are far apart from each other, are each rotatably mounted with an auxiliary roller 28. The tops of the two swing rods 26 on the same grinding structure, which are close to each other, are each rotatably mounted with an active roller 30 via an active shaft 29. The bottoms of the swing rods 26 are each rotatably mounted with a driven roller 31. An inverted isosceles trapezoidal plate 32 is mounted on the bottom of the straight rod 22. The isosceles trapezoidal plate 32 and the driven roller 31 are pressed against each other. The isosceles trapezoidal plate 32 and the inner wall of the groove 23 are connected by a third elastic element 33.

[0029] Specifically, because the ceramic roller body 3 is placed between the two support rollers 4, the two support rollers 4 can drive the ceramic roller body 3 to rotate. However, during the rotation of the ceramic roller body 3 between the two support rollers 4, the ceramic roller body 3 may roll out of the section between the two support rollers 4, causing damage to the ceramic roller body 3. In this embodiment, when the ceramic roller body 3 needs to be polished, the operator places the ceramic roller body 3 on the support roller 24. Under the action of its own weight, the ceramic roller body 3 can move the support roller 24 and the straight rod 22 into one end of the groove 23, so that... The straight rod 22 drives the isosceles trapezoidal plate 32 to move towards one end of the groove 23. The isosceles trapezoidal plate 32 compresses the third elastic element 33 (the third elastic element 33 is a component capable of telescoping and resetting, preferably a spring), causing the third elastic element 33 to be in a compressed state. Simultaneously, as the ceramic roller body 3 pushes the support roller 24 and the straight rod 22 towards one end of the groove 23, the second elastic element 27 (the second elastic element 27 is a component capable of telescoping and resetting, preferably a spring) provides elastic force to the swing rod 26, so that the isosceles trapezoidal plate 32 and the driven roller 31 are always in a state of mutual contact. During the movement of the isosceles trapezoidal plate 32 towards one end of the groove 23... During the process, the isosceles trapezoidal plate 32 pushes the two driven rollers 31 to move away from each other (that is, the driven rollers 31 move to both sides of the groove 23). The two driven rollers 31 drive the swing rod 26 to rotate around the positioning shaft 25. The swing rod 26 drives the driving roller 30 and the auxiliary roller 28 to press against the outer wall of the ceramic roller body 3, so that the support roller 24, the driving roller 30 and the auxiliary roller 28 can perform a wrapping and positioning operation on the outer wall of the ceramic roller body 3. Through the support roller 24, the driving roller 30 and the auxiliary roller 28, the ceramic roller body 3 can be stably positioned, which can effectively prevent the ceramic roller body 3 from rolling off the frame 1, thereby improving the stability of the grinding of the ceramic roller body 3. After the ceramic roller body 3 is polished, the worker removes the ceramic roller body 3 from the top gap of the support roller 24, the active roller 30, and the auxiliary roller 28, so that the ceramic roller body 3 no longer applies pressure to the support roller 24. Under the rebound action of the third elastic element 33, the third elastic element 33 pushes the isosceles trapezoidal plate 32 and the straight rod 22 to move towards the outside end of the groove 23. Simultaneously, under the rebound action of the second elastic element 27, the second elastic element 27 pushes the swing rod 26 to rotate around the positioning shaft 25, so that the swing rod 26 drives the active roller 30 and the auxiliary roller 28 to disengage from the ceramic roller body 3, thereby allowing the ceramic roller body 3 to be removed from the frame 1.

[0030] In another embodiment of the present invention, the drive shaft 29 is located on the outer side of the frame 1, passing through the frame 1 and connected to a second synchronous pulley 34. On the outer wall of the frame 1, at the positions of the positioning shafts 25 of the two bearing units on the same grinding structure, a power shaft 35 is rotatably installed, that is, the axes of the power shaft 35 and the positioning shaft 25 coincide. A third synchronous pulley 36 is connected to the power shaft 35. Each set of second synchronous pulleys 34 and third synchronous pulleys 36 is connected by a second synchronous belt 37. A fourth synchronous pulley 38 is also connected to the power shaft 35. Two fourth synchronous pulleys 38 on the same grinding structure are connected by a third synchronous belt 39. A third driving member 40 is provided on the frame 1. The output end of the third driving member 40 is connected to one of the drive shafts 29.

[0031] Specifically, during the rotation of the swing rod 26 around the positioning shaft 25, as the swing rod 26 drives the active roller 30 and auxiliary roller 28 to press against the outer wall of the ceramic roller body 3, the swing shaft drives the active shaft 29 and the second synchronous pulley 34 to rotate. However, since the axis of the power shaft 35 and the axis of the positioning shaft 25 coincide, the distance between the third synchronous pulley 36 on the power shaft 35 and the second synchronous pulley 34 on the active shaft 29 is the same as the distance between the axis of the positioning shaft 25 and the axis of the active shaft 29. This ensures that the length of the second synchronous belt 37 between the third synchronous pulley 36 and the second synchronous pulley 34 remains unchanged when the swing rod 26 rotates. The second synchronous belt 37 still transmits power between the third synchronous pulley 36 and the second synchronous pulley 34 when the swing rod 26 rotates. Similarly, the distance between the active shafts 29 does not change, so the distance between the two fourth synchronous pulleys 38 does not change, and the length of the third synchronous belt 39 does not change. When it is necessary to drive the ceramic roller body 3 to rotate, the third drive component is activated. 40 (the third driving component 40 is a device capable of forward and reverse rotation at the output end, preferably a motor) drives the drive shaft 29 to rotate, the drive shaft 29 drives the fourth synchronous pulley 38 to rotate, and the two fourth synchronous pulleys 38 are connected by a third synchronous belt 39, so that the two fourth synchronous pulleys 38 rotate synchronously under the transmission action of the third synchronous belt 39. Synchronously, the fourth synchronous pulleys 38 and the drive shaft 35 drive the third synchronous pulley 36 to rotate, and the third synchronous pulley 36 and the second synchronous pulley 34 are connected by a second synchronous belt 37, so that the third synchronous pulley... The second synchronous belt 37 drives the second synchronous pulley 34 to rotate, which in turn drives the drive shaft 29 to rotate. The drive shaft 29 then drives the drive roller 30 to rotate, which in turn drives the ceramic roller body 3 to rotate. This provides rotational power for the ceramic roller body 3 to be ground. Furthermore, the support roller 24, drive roller 30, and auxiliary roller 28 position the ceramic roller body 3 and provide rotational power, making the rotation of the ceramic roller body 3 more stable and preventing the ceramic roller body 3 from falling out of the frame 1.

[0032] In another embodiment of the present invention, two L-shaped plates 41 are symmetrically installed on the side wall of the frame 1. A first rack 42 is slidably installed on the L-shaped plate 41, and a second rack 43 is slidably installed on the side wall of the frame 1. The second rack 43 slides through the frame 1. Two square plates 44 are symmetrically installed on both sides of the first rack 42 and the second rack 43 on the L-shaped plate 41. A transmission gear 45 is rotatably installed on the portion of the two square plates 44 between the first rack 42 and the second rack 43. The transmission gear 45 is meshed with the first rack 42 and the second rack 43 respectively. The second rack 43 and the inner wall of the L-shaped plate 41 are connected by a fourth elastic element 46. A U-shaped frame 47 is provided on the first rack 42. A grinding plate 48 is provided at each end of the U-shaped frame 47. The grinding plate 48 and the ceramic roller body 3 are adapted to each other.

[0033] Specifically, while the support roller 24, drive roller 30, and auxiliary roller 28 provide circumferential positioning for the ceramic roller body 3, the grinding disc 2 may push the ceramic roller body 3 axially during its linear reciprocating motion. This could cause one end of the ceramic roller body 3 to slide out from between the support roller 24, drive roller 30, and auxiliary roller 28 along the axial direction of the support roller 24, thus affecting the grinding efficiency of the ceramic roller body 3. In this embodiment, even when the grinding disc 2 moves the ceramic roller body 3 towards the grinding plate 48 during its linear motion, the ceramic roller body 3 moves to a position where it is pressed against the grinding plate 48. This causes the grinding plate 48 to limit the ceramic roller body 3 in the axial direction. When the ceramic roller body 3 and the grinding plate 48 are pressed together, it means that the grinding disc 2 has already driven the ceramic roller body 3 to move axially. Therefore, it is necessary to push the ceramic roller body 3 to move axially, and the direction of the axial movement of the ceramic roller body 3 is opposite to the direction of movement of the grinding disc 2. In this embodiment, during the grinding operation of the ceramic roller body 3 by the driven plate 8 through the pressing plate 11 and the grinding disc 2, when the driven plate 8 moves to press against the second rack 43, the driven plate 8 pushes the second rack 43 to move towards the outside end of the frame 1. The second rack 43 is in contact with the fourth elastic element 46 (the fourth elastic element 46 is an element that can extend and retract and return, preferably an elastic element). The spring performs a pressing operation, causing the fourth elastic element 46 to be in a compressed state. Since both the second rack 43 and the first rack 42 are meshed with the transmission gear 45, as the second rack 43 moves towards the outside of the frame 1, the second rack 43 drives the transmission gear 45 to rotate. The transmission gear 45 drives the first rack 42 to move towards the end closer to the frame 1. The first rack 42 drives the U-shaped frame 47 and the grinding plate 48 to press against the end of the ceramic roller body 3. The U-shaped frame 47 and the grinding plate 48 push the ceramic roller body 3 in the opposite direction of the linear movement of the grinding disc 2 until the ceramic roller body 3 moves to the initial placement position, ensuring that the ceramic roller body 3 is in a stable grinding position. Simultaneously, the ceramic roller body 3 moves in the direction of the active roller 3. Driven by the rotation of the 0, the grinding plate 48 can perform grinding operations on the end of the ceramic roller body 3, making the end of the ceramic roller body 3 smooth. As those skilled in the art will know, in order to ensure the stability of the grinding plate 48 pushing the second rack 43, a passive plate 49 is slidably arranged in the middle of the grinding plate 48. The passive plate 49 and the grinding plate 48 are connected by a sixth elastic member 50. A limit rod is provided in the middle of the sixth elastic member 50. When the driven plate 8 and the second rack 43 are pressed against each other, the passive plate 49 on the driven plate 8 and the second rack 43 are pressed against each other, so that the passive plate 49 presses against the sixth elastic member 50 (the sixth elastic member 50 is a component that can extend and return to its original position, preferably a spring).This allows the passive plate 49 to reciprocate until it abuts against the limiting rod. When the passive plate 49 and the limiting rod are in contact, the ceramic roller body 3 moves to its initial suitable position on the supporting roller 24 (i.e., the length of the ceramic roller body 3 abutting against the supporting roller 24 is the same). To ensure that the grinding plate 48 is located in the middle position of the ceramic roller body 3, preferably, for example... Figure 11 As shown, each end of the U-shaped frame 47 has a slot 51, and a grinding plate 48 is slidably installed in the slot 51. The side wall of the grinding plate 48 and the side wall of the straight rod 22 are connected by a telescopic connecting rod 52. When the ceramic roller body 3 is placed on the support roller 24, under the action of its own weight, the ceramic roller body 3 can move the support roller 24 and the straight rod 22 into one end of the groove 23. During this process, the straight rod 22 drives the telescopic connecting rod 52 to move into one end of the groove 23 (that is, the telescopic connecting rod 52 moves towards the bottom of the frame 1). The telescopic connecting rod 52 drives the grinding plate 48 to align with the axis of the ceramic roller body 3, so that the grinding plate 48 can always be aligned with the axis of the ceramic roller body 3. Similarly, when the first rack 42 drives the U-shaped frame 47 and the grinding plate 48 to move closer to the ceramic roller body 3, the grinding plate 48 squeezes and retracts the telescopic connecting rod 52. The grinding plate 48 is pressed against the end of the ceramic roller body 3, so that the grinding plate 48 can push the ceramic roller body 3 to move axially and grind the end of the rotating ceramic roller body 3. During the reciprocating motion of the driven plate 8 and the grinding disc 2, there are several effects: (1) The driven plate 8 drives the grinding disc 2 to grind the ceramic roller body 3; (2) The driven plate 8 drives the U-shaped frame 47 and the grinding plate 48 to move axially through the second rack 43 and the first rack 42, so as to ensure the stability of the grinding position of the ceramic roller body 3; (3) The grinding plate 48 and the ceramic roller body 3 are pressed against each other, so that the grinding plate 48 can perform a comprehensive grinding operation on the ceramic roller body 3; (4) The vacuum cleaner 18 on the driven plate 8 can collect the grinding debris to prevent the grinding debris from affecting the grinding of the ceramic roller body 3.
