Description

Technical Field

[0001] This utility model relates to the field of quartz stone slab polishing technology, and in particular to a polishing device that adapts to quartz stone slabs with different flatness. Background Technology

[0002] Quartz stone slabs are widely used in kitchen countertops, bathroom countertops, and commercial space decoration due to their durability and aesthetic appeal. However, before actual installation, the slabs need to be cut and processed according to the specific dimensions and shape of the space. The cutting process often results in obvious cutting marks, burrs, or irregular edges on the sides of the slabs. These problems not only affect the appearance but may also pose safety hazards. Therefore, fine polishing of the sides of the quartz stone slabs after cutting and processing is an essential step.

[0003] Common polishing methods rely on manual polishing using handheld angle grinders or specialized polishing machines. While this method can flexibly adapt to different shaped slabs, manual operation is not only labor-intensive but also has low overall production efficiency, making it difficult to meet the needs of batch processing. Alternatively, after fixing the quartz slab, it is rotated around an axis, and then a polishing device in a fixed position is used to continuously polish the edges of the slab. Although this method improves polishing efficiency to some extent, since its polishing principle relies on the rotation of the workpiece to achieve full coverage, it is only suitable for round or centrally symmetrical quartz slabs. For slabs with straight edges, polygons, or irregular contours, this method cannot achieve uniform polishing, affecting the quality and usability of the finished product. Utility Model Content

[0004] This invention provides a grinding device that adapts to quartz stone slabs with different flatness. While ensuring grinding efficiency and quality, the device can adapt to the specifications and contour characteristics of different slabs to meet the production requirements of modern processing industries for automation, flexibility and intelligence.

[0005] The technical solution of this utility model is: a grinding device for quartz stone slabs with different flatness, comprising: a main frame, a rotating component, and a controller; the device further comprises: a fixed frame, fixedly connected to the main frame; an electric push rod, fixedly connected to the fixed frame; a mounting frame, fixedly connected to the end of the electric push rod; a motor, fixedly connected to the mounting frame and forming an electrical signal connection with the controller; a grinding roller, rotatably connected to the mounting frame, with its rotating shaft fixedly connected to the output end of the motor; a support frame, fixedly connected to the main frame and disposed on the side of the grinding roller, wherein the quartz stone slab will pass through the support frame and the grinding roller in sequence when the rotating component rotates; a distance measuring device, fixedly connected to the support frame, its detection position being aligned with the reference position of the grinding roller, used to measure the distance from the edge of the quartz stone slab to the reference position of the grinding roller, and forming an electrical signal connection with the electric push rod.

[0006] Furthermore, the device also includes: a storage tank, fixedly connected to the lower part of the main frame, for storing clean water; a water supply pipe, one end of which is fixedly connected to the storage tank and communicates with the inside of the storage tank; a water pump, fixedly connected to the water supply pipe and communicates with the inside of the water supply pipe, for outputting water from the storage tank through the water supply pipe, and forming an electrical signal connection with the controller; a spray pipe, fixedly connected to the mounting frame, with its nozzle facing the grinding roller; and a telescopic pipe, fixedly connected between the other end of the water supply pipe and the spray pipe, which will extend and retract synchronously with the position adjustment of the grinding roller.

[0007] Furthermore, the device also includes: a protective assembly disposed outside the rangefinder for protecting the rangefinder, comprising: a housing fixedly connected to a support frame, wherein the rangefinder is embedded therein, and the housing has an opening on the side facing the rotating assembly; a transparent plate fixedly connected to the opening of the housing; an electric track fixedly connected to the side of the opening of the housing, which forms an electrical signal connection with the controller; and a scraper slidably connected to the opening of the housing, maintaining contact with the surface of the transparent plate, and one end of which is fixedly connected to the control end of the electric track.

[0008] Furthermore, the device also includes an exhaust fan, disposed on the housing, for enhancing air circulation inside the housing.

[0009] Furthermore, the device also includes a wastewater collection tank, which is fixedly connected to the main frame and located below the grinding roller, for recycling wastewater. The wastewater collection tank is equipped with a filter screen for solid-liquid separation.

[0010] Furthermore, the device also includes a splash guard, which is fixedly connected to the mounting frame and covers the outside of the grinding roller in a semi-enclosed shape, with an opening only on the side that contacts the quartz stone slab.

[0011] The beneficial effects are: This utility model uses a rangefinder to detect the positional changes of the edge of the quartz stone slab in real time, and dynamically controls and adjusts the position of the grinding roller, so that the grinding roller always maintains the best grinding contact state with the edge of the quartz stone slab, ensuring the consistency of the grinding effect of all parts of the quartz stone slab; compared with the existing technology, it improves the convenience and comfort of operation and increases the processing efficiency.

[0012] This invention sprays water toward the grinding roller, which on the one hand reduces the temperature of the contact area between the grinding roller and the quartz stone slab through the water flow, preventing high temperatures from affecting the structural life or the performance of the quartz stone slab; on the other hand, it can promptly suppress dust splashing generated during the grinding process, thereby improving the safety of the operation and helping to maintain the cleanliness of the working environment.

[0013] This invention uses a protective component to prevent splashes of water or dust from directly contacting the rangefinder, thereby ensuring its detection accuracy. It can also controllably scrape off any mixture adhering to the protective component to restore its cleanliness, ensuring that the rangefinder can always accurately complete the distance measurement work.

Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] Example: A polishing device for quartz stone slabs with varying flatness, such as... Figures 1-3As shown, the device includes: a main frame 1; a rotating assembly 2, assembled in the middle of the main frame 1, used to stably fix and drive the quartz stone slab to rotate (the rotation direction is counterclockwise when viewed from above), consisting of a crossbeam, a cylinder, and two turntables. The crossbeam is fixed in the middle of the main frame 1, the cylinder is fixed in the center of the crossbeam, and the two turntables are rotatably connected to the connecting rod ends of the main frame 1 and the cylinder, respectively. The turntables on the main frame 1 have built-in drive devices; a controller 3, fixedly installed on the main frame 1, used to control the opening and closing of the device, and forms an electrical signal connection with the cylinder and the drive device built into the turntables in the rotating assembly 2; the device also includes: a fixed frame 4, fixedly installed on the main frame 1, located in front of the rotating assembly 2; and an electric push rod 5, fixed... Mounted on the fixed frame 4; Mounting bracket 6, fixedly mounted on the end of the electric push rod 5; Motor 7, fixedly mounted on the mounting bracket 6, forming an electrical signal connection with the controller 3; Grinding roller 8, rotatably mounted on the mounting bracket 6, its rotating shaft is fixedly connected to the output end of the motor 7, and the motor 7 provides the rotational driving force; Support frame 9, fixedly mounted on the main frame 1, set on the left side of the grinding roller 8, when the quartz stone slab is driven counterclockwise by the rotating component 2, it will pass through the support frame 9 and the grinding roller 8 in sequence; Rangefinder 10, fixedly mounted on the support frame 9, its detection position is kept on the same straight line as the reference position of the grinding roller 8, used to measure the distance from the edge of the quartz stone slab to the reference position of the grinding roller 8, and it forms an electrical signal connection with the electric push rod 5.

[0021] The quartz stone slab is placed between the two turntables in the rotating assembly 2. The controller 3 is used to start the cylinder (the specific control process of the controller 3 will be omitted below and the operation of each component will be described directly), controlling the turntable at the end of its connecting rod to move closer to the turntable on the main frame 1, thereby stably clamping the quartz stone slab. Then, the built-in drive in the turntable is activated, causing the quartz stone slab to rotate. During this process, the rangefinder 10 detects the position change of the edge of the quartz stone slab in real time and transmits the signal to the electric push rod 5. The electric push rod 5 then extends and retracts synchronously according to the detection data, dynamically adjusting the position of the mounting frame 6 and the grinding roller 8, so that the grinding roller 8 always maintains the best grinding contact state with the edge of the quartz stone slab, ensuring the consistency of the grinding effect of all parts of the quartz stone slab. Compared with the existing technology, this device not only improves the convenience and comfort of operation, but also significantly improves the processing efficiency, and has obvious technical advantages.

[0022] like Figure 1 and Figure 3As shown, the device also includes: a storage tank 11, fixedly installed on the lower part of the main frame 1, for storing clean water; a water supply pipe 12, one end of which is fixedly installed on the storage tank 11 and communicates with the inside of the storage tank 11; a water pump 13, fixedly installed on the water supply pipe 12 and communicates with the inside of the water supply pipe 12, for outputting the water in the storage tank 11 through the water supply pipe 12, and forming an electrical signal connection with the controller 3; a spray pipe 15, fixedly installed on the mounting frame 6, with its nozzle facing the grinding roller 8; and a telescopic pipe 14, fixedly installed between the other end of the water supply pipe 12 and the spray pipe 15, which will extend and retract synchronously with the position adjustment of the grinding roller 8 to ensure continuous water flow.

[0023] While the grinding roller 8 is grinding the quartz stone slab, the water pump 13 starts simultaneously, delivering water from the storage tank 11 to the spray pipe 15 via the water supply pipe 12 and the telescopic pipe 14, and finally spraying water onto the grinding roller 8. On the one hand, the water flow reduces the temperature of the contact area between the grinding roller 8 and the quartz stone slab, preventing high temperatures from affecting the lifespan of the device or the performance of the quartz stone slab. On the other hand, it can promptly suppress dust splashing during the grinding process, thus improving safety during operation and helping to maintain the cleanliness of the working environment of the device.

[0024] like Figure 1 and Figure 4 As shown, the device also includes: a protective component 16, assembled on the outside of the rangefinder 10, for protecting the rangefinder 10, comprising: a housing 1601, fixedly mounted on the support frame 9, with the rangefinder 10 built into it, and an opening on the rear side of the housing 1601; a transparent plate 1603, fixedly mounted at the opening of the housing 1601, forming a closed protection while avoiding affecting the normal use of the rangefinder 10; an electric track 1602, fixedly mounted on the upper side of the opening of the housing 1601, which forms an electrical signal connection with the controller 3; and a scraper 1604, slidably mounted at the opening of the housing 1601, maintaining contact with the surface of the transparent plate 1603, and one end of which is fixedly connected to the control end of the electric track 1602.

[0025] The combined structure of the outer shell 1601 and the transparent plate 1603 effectively prevents splashed water or dust from directly contacting the rangefinder 10, thus ensuring its detection accuracy. During the grinding process, the surface of the transparent plate 1603 of the protective component 16 may be covered with a mixture of dust and water generated during grinding, affecting the detection field of the rangefinder 10. At this time, the electric track 1602 is activated, which drives the scraper 1604 to move along the surface of the transparent plate 1603 to scrape off the attached mixture and restore the cleanliness of the transparent plate 1603, ensuring that the rangefinder 10 can always accurately complete the distance measurement work.

[0026] like Figure 1 , Figure 3 and Figure 4As shown, the device also includes: an exhaust fan 17, mounted on the bottom of the housing 1601, used to enhance air circulation inside the housing 1601, which can effectively avoid the problem of high humidity inside the housing 1601 caused by factors such as temperature difference, and improve the safety of the rangefinder 10; a wastewater collection tank 18, fixedly installed on the main frame 1, located below the grinding roller 8, used to collect wastewater generated during the grinding process, preventing wastewater from polluting the equipment operating environment. In addition, the wastewater collection tank 18 is equipped with a filter screen to achieve solid-liquid separation, providing convenience for subsequent wastewater treatment; and a splash guard 19, fixedly installed on the mounting frame 6, which semi-encloses the outside of the grinding roller 8, with only the front and bottom openings to further block dust splashes.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
