Description

Technical Field

[0001] The utility model relates to the technical field of building board processing, and particularly relates to a polishing device for building board processing. Background Technique

[0002] Building boards are flat rectangular building material boards made in standard sizes and are applied in the construction industry to be used as components for walls, ceilings or floors. Building boards are classified into thin boards, medium boards, thick boards and extra-thick boards according to their own thickness. When processing building boards, polishing is required to remove burrs on the board surface to make the board surface flat. Therefore, a polishing device is needed.

[0003] After retrieval, the patent with the patent publication number CN216066935U discloses a polishing device for building board processing that is easy to adjust. Although this device can clamp and fix building boards of different specifications during use to prevent the board from shifting during grinding, this device can only grind the surface of the board during use and cannot grind the end face of the board. During the processing of building boards, the flatness and smoothness of the end face are equally important, especially when precise docking or installation is required. Therefore, this lack of function limits the application range and processing effect of the device, increasing the complexity and cost of subsequent processing or correction. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a polishing device for building board processing, which solves the problems raised in the background technique.

[0005] The solution of the utility model to the above technical problems is as follows:

[0006] A polishing device for building board processing includes a base, and a grinding device is erected above the base;

[0007] The grinding device is provided with a frame. A fixing plate is arranged in the base. After the grinding device is docked with the fixing plate through the frame, it is locked and fixed by bolts. A driving roller and a supporting roller are installed on the frame. A grinding belt is installed on the driving roller and the supporting roller in a transmission manner. A motor is installed below the driving roller on the frame. The motor is connected with the driving roller through a synchronous belt in a transmission manner. A limiting shell is arranged at the end of the grinding belt on the frame, and the limiting shell is in a U shape. There is a discharge port between the limiting shell and the frame, and the discharge port extends into the base;

[0008] A receiving cavity is opened in the base. The fixing plate is located in the receiving cavity, and a storage box is inserted and installed in the receiving cavity.

[0009] On the basis of the above technical solution, the utility model can also be improved as follows.

[0010] Furthermore, a plurality of support rollers are provided, and the plurality of support rollers are evenly distributed within the frame, and the power roller is located below the horizontal plane of the support rollers.

[0011] The beneficial effects of adopting the above further solution are as follows:

[0012] The plurality of support rollers are evenly distributed within the frame, which can more effectively disperse the weight of the workpiece or plate, reduce the load on a single support roller, and thus improve the stability and load-bearing capacity of the overall system. This design enables the system to operate smoothly when facing heavy workpieces or plates, reducing vibrations and offsets caused by uneven forces. The evenly distributed support rollers help maintain the smoothness and consistency of the workpiece or plate during the processing, reducing processing errors caused by workpiece shaking or position deviation. The power roller is located below the horizontal plane of the support rollers, which can ensure stable support and positioning of the workpiece during the processing, thereby further improving the processing accuracy.

[0013] Furthermore, a tensioning roller is installed below the horizontal plane of the power roller within the frame, a chute adapted to the tensioning roller is provided on the frame, and the tensioning roller is slidably installed within the chute of the frame.

[0014] The beneficial effects of adopting the above further solution are as follows:

[0015] The tensioning roller is slidably installed within the chute of the frame, enabling the user to conveniently adjust the position of the tensioning roller as needed. This design allows the tensioning degree of the grinding belt to be flexibly adjusted to adapt to plates of different thicknesses or materials, as well as different processing requirements. The reasonable adjustment of the tensioning roller can ensure that the grinding belt maintains an appropriate tension, which is crucial for improving the processing accuracy. An overly tight or loose grinding belt may lead to a decline in processing quality, while the adjustment function of the tensioning roller helps avoid such situations. Appropriate tension helps reduce slipping and wear of the grinding belt during transmission, thereby extending the service life of the grinding belt. At the same time, a stable tension state also helps reduce vibrations and impacts on the frame and other transmission components, reducing the overall wear of the equipment.

[0016] Furthermore, a pull rod is installed below the frame at the position of the tensioning roller, and the two ends of the pull rod and the tensioning roller are elastically connected by a tension spring.

[0017] The beneficial effects of adopting the above further solution are as follows:

[0018] The elastic connection of the tension spring provides an automatic adjustment mechanism for the expanding roller. When the tension of the grinding belt changes due to wear, thermal expansion and contraction, etc. during the transmission process, the tension spring can automatically adjust the position of the expanding roller to maintain the appropriate tension of the grinding belt. This automatic adjustment function helps to maintain the stability of the system and reduce the processing errors and safety hazards caused by the change of tension. The elastic connection of the tension spring can also reduce vibration and noise to a certain extent. During the grinding process, due to the rotation of the driving roller and the feeding of the plate, the system may generate certain vibration and noise. The elastic effect of the tension spring can absorb part of the vibration energy, reduce the vibration amplitude and noise level, and improve the comfort of the working environment.

[0019] Furthermore, the fixed plate is located above the storage box.

[0020] The beneficial effect of adopting the above further scheme is:

[0021] Setting the fixed plate above the storage box can optimize the spatial layout of the entire polishing device. This layout makes the structure of the device more compact, reduces the floor area, and improves the cleanliness and space utilization efficiency of the working area. The fixed plate, as a platform for supporting and fixing the grinding device, has strong stability and load-bearing capacity. Placing the storage box in the accommodation cavity below the fixed plate can protect the storage box from the direct impact or vibration of the equipment above, thus protecting the storage box from damage.

[0022] Furthermore, the cross-section of the accommodation cavity is trapezoidal, and the end of the accommodation cavity is higher than the lowest end of the discharge port.

[0023] The beneficial effect of adopting the above further scheme is:

[0024] The end of the accommodation cavity of the base is higher than the lowest end of the discharge port. This design effectively avoids the situation where waste materials flow back to the grinding area. Because the waste materials are concentrated at the end of the base, they are not easily refluxed to the grinding belt or the limiting shell, preventing the equipment jamming problem caused by the waste materials getting stuck between the grinding belt and the limiting shell. If the waste materials cannot be effectively discharged, it may lead to excessive wear of the polishing belt, increased equipment temperature, or affect the grinding effect of the plate surface. Through this design, the contact between the waste materials and the grinding belt and the limiting shell is reduced, thereby reducing the wear rate of these components and extending the service life of the equipment. In addition, avoiding the reflux of waste materials also reduces the friction between the grinding belt and the plate, ensuring the accuracy and uniformity of the grinding effect.

[0025] Furthermore, the grinding device is obliquely mounted on the base through the frame and the fixed plate, and the grinding belt at the support roller is in a horizontal state, while the grinding belt at the connection between the driving roller and the support roller is in an inclined state.

[0026] The beneficial effect of adopting the above further scheme is:

[0027] The design of the inclined abrasive belt enables the grinding device to process plates of different shapes and sizes. The horizontal abrasive belt is more suitable for large-area flat grinding of plates, while the inclined abrasive belt is particularly suitable for processing irregular areas at the edges, end faces, or corners of specific parts of the plate. The horizontal abrasive belt provides a stable working surface, ensuring uniform stress on the plate during large-area grinding and a smoother and more even grinding effect. At the same time, the inclined abrasive belt can better contact the sides or edges of specific parts of the plate, with higher precision and efficiency when dealing with complex shapes.

[0028] The utility model provides a polishing device for processing building plates. It has the following beneficial effects:

[0029] Through the coordinated action of the driving roller and multiple supporting rollers, the abrasive belt can be stably conveyed and effectively polish the building plates. In particular, the abrasive belt at the connection between the driving roller and the supporting roller is designed to be inclined, which helps to uniformly apply pressure at different angles, improve the polishing effect, and reduce the unevenness on the surface of the plate.

[0030] The frame is provided with a sliding groove, and the tensioning roller can slide in the sliding groove. This design makes it simple and quick to adjust the tension of the abrasive belt. The tensioning roller is connected to the frame through a pull rod and a tension spring, which allows users to adjust the tension of the abrasive belt according to the thickness of the plate and the polishing requirements. Appropriate tension can ensure stability and uniformity during the polishing process and improve the polishing quality. At the same time, the entire grinding device is docked with the base through the frame and the fixing plate and locked and fixed by bolts. This modular design facilitates the disassembly, installation, and maintenance of the equipment.

[0031] The design of the accommodation cavity and the storage box opened in the base helps to collect the dust and debris generated during the polishing process. The trapezoidal cross-section accommodation cavity can guide the dust and debris to move towards the discharge port and finally fall into the storage box, keeping the working environment clean and reducing the health hazards of dust to the operators. The entire polishing device is structurally compact. The grinding device above the base is inclined, which not only saves floor space but also makes the polishing process smoother. At the same time, the end of the abrasive belt is provided with a U-shaped limit shell and a discharge port to ensure the smooth discharge of the polished plate and improve the working efficiency.

[0040] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0041] Please refer to Figures 1 to 4 As shown, the embodiments provided by the present utility model are as follows:

[0042] Embodiment 1

[0043] A polishing device for processing building panels includes a base 2, with a grinding device 1 mounted above the base 2. The grinding device 1 is provided with a frame 109, and a fixing plate 201 is provided within the base 2. The grinding device 1 is fixed to the fixing plate 201 by bolts after being docked with the frame 109. A power roller 102 and a support roller 107 are mounted on the frame 109. There are multiple support rollers 107, and the multiple support rollers 107 are evenly distributed within the frame 109. The power roller 102 is located below the horizontal plane of the support rollers 107. The multiple support rollers 107 are evenly distributed within the frame 109. This distribution method can more effectively disperse the weight of the workpiece or panel, thereby reducing the load borne by a single support roller 107, thereby improving the stability and load-bearing capacity of the entire system. In this way, even when facing heavy workpieces or panels, the system can maintain a stable operating state and reduce vibration and deviation caused by uneven force. The evenly distributed support rollers 107 also help maintain the stability and consistency of the workpiece or plate during the processing, reducing processing errors caused by workpiece shaking or position offset. The power roller 102 is located below the horizontal plane of the support roller 107. This layout can ensure that the workpiece obtains stable support and positioning during the processing, thereby further improving the processing accuracy. The grinding device 1 is tilted on the base 2 through the frame 109 and the fixed plate 201, and the grinding belt 101 at the support roller 107 is in a horizontal state. The grinding belt 101 at the connection between the power roller 102 and the support roller 107 is in an inclined state. The design of the inclined grinding belt 101 enables the grinding device 1 to process plates of different shapes and sizes. The horizontal grinding belt 101 is more suitable for large-area flat grinding of plates, while the tilted grinding belt 101 is particularly suitable for processing irregular areas of specific edges, end faces or corners of plates. The horizontal grinding belt 101 provides a stable working surface, ensuring that the plate is evenly stressed when grinding a large area, and the grinding effect is flatter and smoother. At the same time, the inclined grinding belt 101 can better contact the side or edge of a specific part of the plate, and has higher precision and efficiency when processing complex shapes. The grinding belt 101 is installed on the power roller 102 and the support roller 107. The frame 109 is located below the power roller 102 and is equipped with a motor 103. The motor 103 and the power roller 102 are connected by a synchronous belt 104. The frame 109 is located below the horizontal surface of the power roller 102 and is equipped with an expansion roller 106. The frame 109 is provided with a slide groove that matches the expansion roller 106. The expansion roller 106 is installed in the slide groove of the frame 109 by sliding. The expansion roller 106 is installed in the slide groove of the frame 109 by sliding. This design allows users to easily adjust the position of the expansion roller 106 according to actual needs. In this way, the tension of the grinding belt 101 by the expansion roller 106 can be flexibly adjusted to accommodate plates of different thicknesses or materials, as well as various processing requirements.Proper adjustment of the expansion roller 106 is crucial to ensuring proper tension on the sanding belt 101. An overly tight or loose sanding belt 101 can result in reduced processing quality, and the adjustment function of the expansion roller 106 helps prevent this. Proper tension not only helps reduce slippage and wear of the sanding belt 101 during transmission, extending its service life, but also helps stabilize the tension, reducing vibration and impact on the frame 109 and other transmission components, and reducing overall wear on the equipment. A pull rod 105 is mounted below the frame 109, elastically connected to the expansion roller 106 at both ends by a tension spring. This elastic connection provides an automatic adjustment mechanism for the expansion roller 106. If the tension of the sanding belt 101 changes during transmission due to wear, thermal expansion, or contraction, the tension spring automatically adjusts the position of the expansion roller 106 to maintain proper tension on the sanding belt 101. This automatic adjustment function helps maintain system stability and reduces processing errors and safety hazards caused by changes in tension. The elastic connection of the tension spring can also reduce vibration and noise to a certain extent. During the grinding process, the system may generate a certain amount of vibration and noise due to the rotation of the power roller 102 and the feeding of the plate. The elastic action of the tension spring can absorb some vibration energy, reducing the vibration amplitude and noise level, and improving the comfort of the working environment. The frame 109 is located at the end of the grinding belt 101 and is provided with a limit housing 108. The limit housing 108 is U-shaped. When grinding the surface of the plate, the plate is placed on the grinding belt 101 through the limit housing 108, and the grinding belt 101 grinds the plate. When the end face of the plate needs to be polished, the user stacks multiple plates and then places the stacked plates longitudinally on the grinding belt 101 with the limit housing 108 to enable the grinding belt 101 to grind the entire end face of the plate. A discharge port 110 is provided between the limiting shell 108 and the frame 109 , and the discharge port 110 extends into the base 2 .

[0044] Example 2

[0045] In order to facilitate the collection and management of grinding debris, for example, Figures 1 to 4As shown, the present invention also includes: a accommodating chamber 202 is provided in the base 2, the cross-section of the accommodating chamber 202 is trapezoidal, and the end of the accommodating chamber 202 is higher than the lowest end of the discharge port 110. The end of the accommodating chamber 202 of the base 2 is higher than the lowest end of the discharge port 110. This design effectively avoids the situation where waste materials flow back to the polishing area. Since the waste materials are concentrated at the end of the base 2, they are not easy to flow back to the polishing belt 101 or the limiting shell 108, thereby preventing the equipment from being stuck between the polishing belt 101 or the limiting shell 108. If the waste materials cannot be effectively discharged, it may cause excessive wear of the polishing belt, increase the temperature of the equipment, or affect the polishing effect of the plate surface. Through this design, the contact between the waste materials and the polishing belt 101 and the limiting shell 108 is reduced, thereby reducing the wear rate of these components and extending the service life of the equipment. In addition, avoiding the backflow of waste also reduces the friction between the grinding belt 101 and the plate, ensuring the accuracy and uniformity of the grinding effect. The fixed plate 201 is located in the accommodating chamber 202, and the storage box 203 is installed in the accommodating chamber 202. The fixed plate 201 is located above the storage box 203. The fixed plate 201 is set above the storage box 203. This layout can optimize the spatial layout of the entire polishing device. Such a design makes the structure of the equipment more compact, reduces the floor space, and improves the cleanliness and space utilization efficiency of the working area. The fixed plate 201 serves as a platform for supporting and fixing the grinding device 1, and its stability and load-bearing capacity are relatively strong. Placing the storage box 203 in the accommodating chamber 202 below the fixed plate 201 can protect the storage box 203 from direct impact or vibration of the upper equipment, thereby protecting the storage box 203 from damage.

[0046] Working principle:

[0047] The polishing device 1 is docked with the fixed plate 201 within the base 2 via the frame 109 and secured with bolts to ensure the stability of the entire polishing device. The motor 103 is mounted below the frame 109 and is connected to the power roller 102 via a timing belt 104. When the motor 103 is turned on, power is transmitted to the power roller 102 via the timing belt 104, causing it to rotate.

[0048] A grinding belt 101 is mounted on a power roller 102 and multiple support rollers 107. The rotation of the power roller 102 drives the grinding belt 101 in a circular motion on the support rollers 107, forming the required polishing trajectory. A sheet is placed on the grinding belt 101 via a retaining housing 108. As the grinding belt 101 moves, the sheet surface comes into contact with the belt and is physically polished, achieving a polishing effect.

[0049] The tensioning roller 106 is connected to the frame 109 through the pull rod 105 and the tension spring and can slide in the chute. By adjusting the position of the pull rod 105, the pressing degree of the tensioning roller 106 on the grinding belt 101 can be changed, thereby adjusting the tension of the grinding belt 101. Appropriate tension helps to ensure the grinding effect and extend the service life of the grinding belt 101.

[0050] When the surface of the plate needs to be ground, the plate is horizontally placed on the grinding belt 101 in the limiting shell 108. With the movement of the grinding belt 101, the surface of the plate comes into contact with the grinding belt 101 and is subjected to uniform grinding, realizing surface polishing.

[0051] When the end face of the plate needs to be ground, the user can stack multiple plates and place them longitudinally on the grinding belt 101 in the limiting shell 108. By adjusting the placement angle and position of the plate, the grinding belt 101 is brought into contact with the end face of the plate for grinding. This design enables the polishing device to meet different processing requirements.

[0052] The accommodation cavity 202 and the storage box 203 provided in the base 2 are used to collect the dust and debris generated during the polishing process. The accommodation cavity 202 with a trapezoidal cross-section can guide the dust and debris to move towards the discharge port 110 and finally fall into the storage box 203. This design helps to keep the working environment clean and reduce the health hazards of dust to the operators.

[0053] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic features of the present invention, the present invention can be implemented in other specific forms.
