Abstract
Description
Technical Field
[0001] This utility model belongs to the field of polishing equipment technology, and specifically relates to a planar automated polishing machine. Background Technology
[0002] Stone and marble, as important materials in the building decoration field, directly affect the decorative effect and service life of the final product due to their surface gloss and smoothness. Polishing, through physical grinding, removes uneven textures and processing marks from the surface of stone / marble, and is a core process for improving the smoothness and texture of stone and marble surfaces. With the building decoration industry's increasing demands for standardization and refinement of materials, efficient and stable polishing machines have become indispensable key equipment in large-scale production.
[0003] During the operation of a production line polishing machine, the high-speed friction between the polishing disc and the stone / marble generates a large amount of heat and dust. The water spray system, through continuous spraying of cooling water, effectively reduces the temperature of the polishing area to prevent thermal damage to the material. Simultaneously, it moistens the dust, causing it to settle, and also lubricates the polishing interface, reducing abrasive wear. Furthermore, the water film can adsorb fine debris to form a suspension, preventing secondary scratches on the processed surface, ultimately achieving efficient and clean polishing. Therefore, water spraying is an indispensable supporting step in the polishing process.
[0004] However, existing automated polishing machines generally use an integrated conveyor belt to transport stone or marble. During the conveyor belt's operation, the spraying water from the water spray system covers the entire surface, forming a wet water film. This film significantly reduces the friction coefficient of the conveyor belt surface, causing relative slippage between the stone or marble and the conveyor belt during transport. This disrupts the positioning stability of the slabs during polishing, causing the polishing trajectory to deviate from the preset path, resulting in low polishing precision and low processing efficiency for the stone and marble.

[0030] Example
[0031] like Figures 1 to 3 As shown, this utility model embodiment provides a planar automated polishing machine for conveying marble 100 and polishing the marble 100. Specifically, it includes a mounting base 200, a belt conveyor mechanism 300, a mounting bracket 400, several polishing components 500, several spraying components 600, and a water collection tank 700.
[0032] Preferably, the belt conveyor mechanism 300 is mounted on the mounting base 200. The belt conveyor mechanism 300 includes a first drive motor 310, a drive shaft 320, a driven shaft 330, auxiliary support shafts 340, a pulley set, and a conveyor belt 350. The first drive motor 310 is mounted on the mounting base 200. The drive shaft 320 and the driven shaft 330 are rotatably mounted at opposite ends of the mounting base 200. The output end of the first drive motor 310 is connected to the drive shaft 320. A plurality of auxiliary support shafts 340 are evenly distributed between the drive shaft 320 and the driven shaft 330 and are rotatably mounted on the base. Mounted on the mounting base 200, the drive shaft 320, driven shaft 330, and auxiliary support shaft 340 are each provided with a plurality of pulley sets along their axial direction. The transmission belt 350 is fitted onto each pulley set in the same row, and the pulley sets are spaced apart from each adjacent row. Notably, each pulley set includes a main pulley, a driven pulley, and an auxiliary pulley. As the names suggest, the main pulleys are evenly distributed on the drive shaft 320, the driven pulleys are evenly distributed on the driven shaft 330, and the auxiliary pulleys are evenly distributed on the auxiliary support shaft 340, with the same number of main pulleys, driven pulleys, and auxiliary pulleys. The main pulleys, driven pulleys, and auxiliary pulleys on the drive shaft 320, driven shaft 330, and auxiliary support shaft 340 are arranged axially correspondingly, and the transmission belt 350 is fitted onto the main pulleys, driven pulleys, and auxiliary pulleys in the same row.
[0033] It should be noted that the first drive motor 310 is connected to the PLC to receive control from the PLC. The connection method between the motor and the PLC is conventional prior art. The specific connection method between the first drive motor 310 and the PLC is not the focus of this application and does not affect the implementation of this application, so it will not be described in detail.
[0034] In some preferred embodiments, the mounting bracket 400 is slidably mounted on the top of the mounting base 200, and the grinding component 500 and the spraying component 600 are alternately mounted on the mounting bracket 400. The water sprayed by the spraying component 600 can be drained away in a timely manner from the gap between the two adjacent conveyor belts 350.
[0035] Furthermore, the mounting base 200 is equipped with a second drive motor, a slide groove, and a lead screw on both its input and output ends. The second drive motor is mounted on the mounting base 200, and the lead screw is rotatably connected to the slide groove. The output end of the second drive motor is connected to the lead screw. The mounting bracket 400 is provided with a slider, and the mounting bracket 400 is slidably disposed in the slide groove via the slider. The slider is provided with a ball screw nut pair to allow the slider to slide (be mounted) on the lead screw. Similarly, the second drive motor is electrically connected to the PLC to receive control from the PLC. The connection method between the motor and the PLC is conventional prior art, and the specific connection method between the second drive motor and the PLC is not the focus of this application and does not affect the implementation of this application, so it will not be described in detail.
[0036] In some preferred embodiments, the mounting base 200 is further provided with a support slide rail 360, which has a plurality of through holes for the wheel surface of the wheel assembly to pass through. The transmission belt 350 is supported by the support slide rail 360 and the wheel assembly, and the horizontal height of the track surface of the support slide rail 360 is lower than the horizontal height of the top surface of the wheel assembly, so that the marble 100 is placed on the belt surface without being affected by the support slide rail 360.
[0037] In some preferred embodiments, the polishing assembly 500 includes a hydraulic cylinder 510, a mounting plate 520, a polishing motor 530, and a polishing disc 540. The hydraulic cylinder 510 is mounted above the mounting bracket 400, with its piston end penetrating downward through the mounting bracket 400. The mounting plate 520 is mounted on the piston end of the hydraulic cylinder 510. The polishing motor 530 is mounted above the mounting plate 520, with its output end penetrating downward through the mounting plate 520 and connected to the polishing disc 540.
[0038] In some preferred embodiments, the spray assembly 600 includes a water spray pipe 610, a water inlet pipe 620, a nozzle 630, and a water spray solenoid valve 640. The water spray pipe 610 vertically penetrates the mounting bracket 400 and is fixedly connected to the mounting bracket 400. The water spray solenoid valve 640 is disposed at the upper end of the water spray pipe 610, and the other end of the water spray solenoid valve 640 is connected to the water inlet pipe 620. The water inlet pipe 620 is connected to an external water supply source. The nozzle 630 is disposed at the outlet of the water spray pipe 610. Further, the spray assembly 600 also includes a through-beam photoelectric sensor 650. The transmitting end of the through-beam photoelectric sensor 650 is mounted on the mounting bracket 400, and its receiving end is connected to the mounting base 200 through a mounting crossbar 660. The horizontal height of the receiving end is lower than the horizontal height of the conveyor belt 350.
[0039] The through-beam photoelectric sensor 650 is used to detect whether the marble 100 passes by. It should be noted that the through-beam photoelectric sensor 650 is electrically connected to the PLC to receive control from the PLC. The connection method between the through-beam photoelectric sensor and the PLC is conventional prior art, and the specific connection method between the through-beam photoelectric sensor 650 and the PLC is not the focus of this application and does not affect the implementation of this application, so it will not be described in detail. The through-beam photoelectric sensor 650 is used in conjunction with the water spray solenoid valve 640. When the marble 100 passes by, the light emitted by the through-beam photoelectric sensor 650 is blocked by the marble 100. The through-beam photoelectric sensor 650 transmits the signal to the PLC, and the PLC controls the water spray solenoid valve 640 to open, realizing the function of "water spraying when marble is present, water stopping when marble is absent", thus saving water consumption. Preferably, in order to prevent spray water from dripping onto the receiving end of the through-beam photoelectric sensor 650 and causing the through-beam photoelectric sensor 650 to malfunction, a transparent waterproof cover is provided outside the receiving end of the through-beam photoelectric sensor 650. Both the transparent waterproof cover and the receiving end of the through-beam photoelectric sensor 650 are connected to the mounting base 200 through a mounting crossbar 660.
[0040] The water inlet pipe 620 is a flexible hose. It should be noted that the hydraulic cylinder 510, polishing motor 530, and water spray solenoid valve 640 are all electrically connected to the PLC to be controlled by the PLC. The connection method between the hydraulic cylinder, motor, solenoid valve and PLC is conventional prior art. The specific connection method between the hydraulic cylinder 510, polishing motor 530, and water spray solenoid valve 640 and the PLC is not the focus of this application and does not affect the implementation of this application, so it will not be described in detail.
[0041] In some preferred embodiments, the water collection tank 700 is disposed at the bottom of the mounting base 200 for collecting the spray water sprayed by the spray assembly 600. The water collection tank 700 has a frustum structure, with its larger collecting surface facing the spray assembly 600. A drain pipe 710 is provided at the bottom end of the water collection tank 700, and a valve 720 is provided on the drain pipe 710.
[0042] The water collection tank 700 is made of aluminum alloy. The valve 720 can be a manual valve or an electric valve. When it is an electric valve, it is electrically connected to the PLC. The specific connection method is conventional existing technology. The choice of connection circuit between the electric valve and the PLC does not affect the function of the PLC in controlling the opening and closing of the electric valve. Therefore, the specific connection circuit will not be described in detail.
[0043] In some preferred embodiments, the outer surface of the conveyor belt 350 is provided with anti-slip texture. By providing the anti-slip texture, the friction between the marble 100 and the conveyor belt 350 is increased, preventing the marble 100 and the conveyor belt 350 from slipping.
[0044] In summary, the automatic polishing machine for flat production lines provided by this utility model divides the traditional whole conveyor belt into several sections, so that the sprayed water can be drained away in a timely manner from the gaps formed between the conveyor belts without accumulating on the belt surface and affecting the marble during the conveying process, thus ensuring the stable conveying of marble.
