Description

Technical Field

[0001] This utility model belongs to the field of ceramic processing technology, and in particular relates to a ceramic slab surface polishing processing device. Background Technology

[0002] Ceramic slabs, as a new type of green and environmentally friendly building material, are widely used in architectural decoration, home furnishings and kitchenware, and commercial spaces due to their high hardness, wear resistance, strong flexural strength, and rich colors and patterns, resulting in continuously growing market demand. Surface polishing is one of the key processes in ceramic slab processing, and its quality directly affects the product's gloss, flatness, and market competitiveness. With the expansion of ceramic slab production capacity and the increasing demands for processing precision from downstream industries, traditional manual or semi-mechanized polishing methods, due to their low efficiency and poor consistency, are no longer sufficient to meet the needs of large-scale, automated production. Therefore, efficient and high-precision automated polishing equipment has become an inevitable trend in the industry.

[0003] Current ceramic slab polishing equipment suffers from the following shortcomings: First, the feeding and positioning rely on manual adjustment, and the slabs are prone to shifting during transport, leading to polishing position deviations and affecting processing accuracy. Second, the clamping mechanisms mostly use rigid clamps (such as mechanical jaws), with non-adjustable clamping force, which can easily cause surface cracking or chipping of the slabs due to stress concentration, especially for large-sized, thin slabs. Third, the pressing and clamping processes are separated, requiring additional manual assistance for fixation, resulting in low automation and limited production efficiency. Fourth, the lack of a guiding and centering structure necessitates frequent tooling changes when feeding slabs of different widths, resulting in poor flexibility. These defects restrict the quality stability and production efficiency of ceramic slab polishing and urgently require improvement.

[0004] To address these issues, we provide a ceramic slab surface polishing device. Utility Model Content

[0005] The purpose of this invention is to provide a ceramic slab surface polishing device. By coordinating the clamping mechanism and the conveying mechanism, it solves the problems of low positioning accuracy and insufficient clamping stability in existing ceramic slab surface polishing devices.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a ceramic slab surface polishing processing device, comprising a base, a grinding mechanism fixedly connected to the top of the base, a hydraulic telescopic cylinder fixedly connected to the top of the base, and a housing fixedly connected to the output end of the hydraulic telescopic cylinder; a clamping mechanism is provided in the inner cavity of the housing, the clamping mechanism including a dual-axis motor fixedly connected to the inner cavity of the housing, a threaded rod fixedly connected to the output shaft of the dual-axis motor, a threaded sleeve threadedly connected to the surface of the threaded rod, a limiting block fixedly connected to one side of the threaded sleeve, and a clamping block fixedly connected to one side of the limiting block; a conveying mechanism is provided on the top of the base, the conveying mechanism including a support frame fixedly connected to the top of the base, a drive motor fixedly connected to one side of the support frame, and a conveying roller fixedly connected to the output shaft of the drive motor.

[0008] The present invention is further configured such that a through hole is provided at the top of the clamping block, a slide rod is slidably connected to the inner cavity of the through hole, a pressure plate is fixedly connected to one end of the slide rod, and the slide rod slides freely in the through hole, so that the pressure plate can adapt to the rock slab surface of different thicknesses and provide a vertically downward elastic clamping force.

[0009] The present invention is further configured such that a limiting plate is fixedly connected to the other end of the slide rod, and a spring is sleeved on the surface of the slide rod. The limiting plate is circular with a diameter larger than the inner diameter of the through hole to prevent the slide rod from detaching from the clamping block. The spring is sleeved on the part of the slide rod located between the limiting plate and the pressure plate. When the machine box moves upward, the limiting plate contacts the baffle on the base and squeezes the spring. The spring is compressed and pushes the pressure plate downward to press the rock plate, thereby achieving adaptive flexible pressing (avoiding rigid clamping that could cause damage to the rock plate).

[0010] The present invention is further configured such that baffles are fixedly connected to both sides of the support frame, and a limiting groove adapted to the limiting block is opened on one side of the chassis. The baffles are used to trigger the pressing action of the pressure plate, and the limiting groove constrains the limiting block to only move vertically to ensure clamping stability. The limiting groove ensures that the threaded sleeve can only move linearly in the horizontal direction to avoid clamping deviation caused by the shaking of the output shaft of the dual-axis motor.

[0011] The present invention is further configured such that a conveyor belt is drivenly connected to the surface of the conveyor roller, and guide frames are fixedly connected to both sides of the support frame by mounting rods.

[0012] The present invention is further configured such that one side of the guide frame is designed with a flared opening, and a guide roller is rotatably connected to the inner side of the guide frame through a bearing seat. The flared opening design means that the width of the opening on the side of the guide frame away from the support frame gradually increases, so as to guide the rock slabs of different widths to smoothly enter the inner side of the guide frame. The guide roller is a cylindrical rubber roller, which is symmetrically installed on the upper and lower surfaces of the inner side of the guide frame through the bearing seat. When the rock slab passes through, it rolls and contacts the guide roller, reducing frictional resistance and avoiding scratches on the surface of the rock slab.

[0013] The present invention is further provided that a control panel is provided on one side of the grinding mechanism. The control panel is a PLC-controlled touch screen, which can adjust the start / stop, speed and stroke of the drive motor, the dual-axis motor and the hydraulic telescopic cylinder to realize the automated operation of the device.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses flared guide frames on both sides of the support frame and guide rollers rotatably connected to the inside to automatically guide ceramic slabs of different widths toward the center of the conveyor belt, reducing manual adjustment, preventing slab conveying deviation, and improving feeding and positioning accuracy. The hydraulic telescopic cylinder, in conjunction with the lifting action of the machine box, integrates clamping, pressing, polishing and unloading processes without manual intervention, realizing full automation of the ceramic slab conveying to polishing and improving production efficiency.

[0016] 2. This utility model uses an elastic clamping mechanism composed of a sliding rod, pressure plate, and spring at the top of the clamping block. With the triggering of the baffle when the machine box rises, the spring compression can adapt to the difference in the thickness of the rock slab, providing a uniform vertical clamping force and avoiding surface cracking or edge chipping caused by rigid clamping. It is suitable for processing rock slabs of different specifications.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figures 1-5 This utility model is a ceramic slab surface polishing processing device, including a base 1, a grinding mechanism 2 fixedly connected to the top of the base 1, a hydraulic telescopic cylinder 3 fixedly connected to the top of the base 1, and a housing 4 fixedly connected to the output end of the hydraulic telescopic cylinder 3; a clamping mechanism is provided in the inner cavity of the housing 4, the clamping mechanism includes a dual-axis motor 5 fixedly connected to the inner cavity of the housing 4, a threaded rod 6 fixedly connected to the output shaft of the dual-axis motor 5, a threaded sleeve 7 threadedly connected to the surface of the threaded rod 6, a limiting block 8 fixedly connected to one side of the threaded sleeve 7, and a clamping block 9 fixedly connected to one side of the limiting block 8; a conveying mechanism is provided on the top of the base 1, the conveying mechanism includes a support frame 10 fixedly connected to the top of the base 1, a drive motor 11 fixedly connected to one side of the support frame 10, and a conveying roller 12 fixedly connected to the output shaft of the drive motor 11.

[0028] Further details: There are two hydraulic telescopic cylinders 3, which are symmetrically arranged along the width of the base 1. The width of the conveyor belt 20 is smaller than the width of the ceramic slab, which facilitates the subsequent clamping operation. There are two threaded rods 6, which are symmetrically arranged and rotate in opposite directions to ensure that when the dual-axis motor 5 rotates, the two threaded sleeves 7 move synchronously towards each other. The automatic feeding and positioning of the slab is achieved through the conveying mechanism and guide frame 21. The clamping mechanism works with the hydraulic telescopic cylinders 3 to complete automatic clamping and pressing without manual intervention, thereby improving production efficiency.

[0029] Example 2

[0030] Please see Figures 1-5Based on embodiment 1, the clamping block 9 has a through hole 13 at the top, and a slide rod 14 is slidably connected to the inner cavity of the through hole 13. A pressure plate 15 is fixedly connected to one end of the slide rod 14, and a limit plate 16 is fixedly connected to the other end of the slide rod 14. A spring 17 is sleeved on the surface of the slide rod 14. Baffles 18 are fixedly connected to both sides of the support frame 10. A limit groove 19 that matches the limit block 8 is opened on one side of the machine box 4. A conveyor belt 20 is drivenly connected to the surface of the conveying roller 12. Guide frames 21 are fixedly connected to both sides of the support frame 10 through mounting rods. One side of the guide frame 21 is designed with a flared mouth. A guide roller 22 is rotatably connected to the inner side of the guide frame 21 through a bearing seat. A control panel 23 is provided on one side of the grinding mechanism 2.

[0031] Further details: The slide bar 14 slides freely within the through hole 13, allowing the pressure plate 15 to adapt to different thicknesses of rock slab surfaces, providing a vertically downward elastic clamping force. The limiting plate 16 is circular with a diameter larger than the inner diameter of the through hole 13, preventing the slide bar 14 from disengaging from the clamping block 9. The spring 17 is sleeved on the portion of the slide bar 14 located between the limiting plate 16 and the pressure plate 15. When the housing 4 moves upward, the limiting plate 16 contacts the baffle 18 on the base 1 and squeezes the spring 17. The spring 17 is compressed, pushing the pressure plate 15 downward to press the rock slab, achieving adaptive flexible clamping (avoiding rigid clamping that could damage the rock slab). The baffle 18 is used to trigger the downward pressing action of the pressure plate 15. The limiting groove 19 constrains the limiting block 8 to only move vertically. The movement ensures stable clamping. The limiting groove 19 ensures that the threaded sleeve 7 can only move in a straight line in the horizontal direction, avoiding clamping deviation caused by the shaking of the output shaft of the dual-axis motor 5. The flared mouth design is such that the opening width of the guide frame 21 gradually increases on the side away from the support frame 10, guiding rock slabs of different widths to smoothly enter the inner side of the guide frame 21. The guide roller 22 is a cylindrical rubber roller, which is symmetrically installed on the upper and lower surfaces of the inner side of the guide frame 21 through bearing seats. When the rock slab passes through, it rolls in contact with the guide roller 22, reducing frictional resistance and avoiding scratches on the surface of the rock slab. The control panel 23 is a PLC control touch screen, which can adjust the start, stop, speed and stroke of the drive motor 11, dual-axis motor 5 and hydraulic telescopic cylinder 3 to realize the automated operation of the device.

[0032] The working principle of this utility model is as follows: the ceramic slab to be polished is transferred from the previous process to the front end of the guide frame 21, and guided into the inner side of the guide frame 21 through the flared guide frame 21, where it rolls and contacts the upper and lower guide rollers 22, and moves along the guide frame 21 toward the center of the conveyor belt 20. The drive motor 11 is started, which drives the conveyor rollers 12 and the conveyor belt 20 to run, and the slab is conveyed to the processing area at a uniform speed.

[0033] After the rock slab reaches the designated position, the dual-axis motor 5 starts, and its output shaft drives the two threaded rods 6 to rotate. Since the threaded rods 6 rotate in opposite directions, the two threaded sleeves 7 move towards each other along the limiting groove 19. The limiting block 8 and the limiting groove 19 restrict their movement to only horizontal. Finally, the two clamping blocks 9 move close to and clamp the sides of the rock slab from the left and right sides.

[0034] Then the hydraulic telescopic cylinder 3 is activated, pushing the machine box 4 to move upward. When the machine box 4 rises, the limiting plate 16 at the top of the clamping block 9 contacts the baffle 18 on the base 1, compressing the compression spring 17 and pushing the slide rod 14 and pressure plate 15 downward until the pressure plate 15 is tightly attached to the upper surface of the rock plate, realizing the dual fixation of the side clamping and top pressing of the rock plate, and avoiding the displacement of the rock plate during the polishing process.

[0035] The grinding mechanism 2 polishes the surface of the rock slab. The control panel 23 adjusts the speed and feed rate. After polishing, the hydraulic telescopic cylinder 3 descends and resets. Then, the dual-axis motor 5 reverses to release the clamp, allowing the rock slab to be placed on the surface of the conveyor belt 20. At this time, the hydraulic telescopic cylinder 3 lifts again to make the machine box 4 detach from the conveyor belt 20. Finally, the drive motor 11 drives the conveyor roller 12 to transport the rock slab to the next process.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
