[0002] During the processing of sheet materials, surface grinding and polishing are often required. Compared to large-size panels, small-size panels generally require higher processing precision. Most existing panel grinding machines have conveyor mechanisms suitable for large-size panel processing and cannot be used for grinding small-size panels with high precision requirements.
[0003] Therefore, it is necessary to develop a conveying mechanism for a panel grinding machine that is designed for high-precision grinding of small-sized panels. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a conveying mechanism for a panel polishing machine, which helps to improve polishing accuracy and is suitable for processing small-sized panels.
[0005] To solve the above-mentioned technical problems, this utility model provides a conveying mechanism for a panel polishing machine, including a belt conveying mechanism and a roller pressing mechanism. The belt conveying mechanism includes a driving pulley, a driven pulley, and a conveying belt. The roller pressing mechanism includes a first conveying roller disposed above the conveying belt and arranged along the conveying direction of the conveying belt. The conveying belt and the first conveying roller respectively contact the bottom surface and the top surface of the panel and drive in the same direction. The roller pressing mechanism and the driving pulley are driven by the same driving mechanism.
[0006] As an improvement to the above solution, the drive mechanism is fixed to the frame, and the frame is provided with a first transition shaft and a second transition shaft. The first transition shaft is coaxially provided with a first gear and a first intermediate rotating wheel, and the second transition shaft is coaxially provided with a second gear and a second intermediate rotating wheel set. The first gear meshes with the second gear.

The second transmission roller is located above the third transmission roller, the upper brush roller is located above the lower brush roller, the upper brush roller is located between two adjacent second transmission rollers, and the lower brush roller is located between two adjacent third transmission rollers.
[0008] As an improvement to the above solution, the cleaning mechanism is disposed at at least one end of the transmission belt, either at the input end or the output end of the transmission belt.
[0009] As an improvement to the above solution, a second transmission wheel is provided at one end of the second transmission roller, and a lower brush transmission wheel is provided at one end of the lower brush roller;
[0010] The lower brush drive wheel is connected to the second intermediate rotating wheel group, and the second drive wheel is connected to the second intermediate rotating wheel group.

[0017] Implementing this utility model has the following beneficial effects:
[0018] This utility model discloses a conveying mechanism for a panel polishing machine. When the panel is conveyed on the belt conveyor mechanism, the first conveyor roller above the belt conveyor mechanism contacts the top surface of the panel. The conveyor belt and the first conveyor roller provide co-directional transmission to the panel. On the one hand, compared with the structure supported by rollers, the panel is supported by the conveyor belt more evenly and can withstand greater polishing pressure without breaking. On the other hand, the cleaning water during the polishing process has an adsorption effect on the panel and the conveyor belt, making it less likely for the panel to move or become misaligned on the conveyor belt. In addition, the roller pressing mechanism and the drive pulley are driven by the same drive mechanism, resulting in good consistency of transmission between the top and bottom surfaces of the panel and good positioning and transmission effect. These factors all contribute to improving polishing accuracy and are particularly suitable for processing small-sized panels. Attached Figure Description

[0024] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.
[0025] like Figure 1 As shown, this utility model discloses a first embodiment of a conveying mechanism for a panel polishing machine, including a belt conveyor mechanism 1 and a roller pressing mechanism. The belt conveyor mechanism 1 includes a driving pulley 11, a driven pulley 12, and a conveyor belt 13 sleeved on the driving pulley 11 and the driven pulley 12. A support plate 3 is continuously arranged between the driving pulley 11 and the driven pulley 12. The roller pressing mechanism includes a first conveyor roller 21 arranged above the conveyor belt 13 and along the conveying direction of the conveyor belt 13. The first conveyor roller 21 is parallel to the driving pulley 11. The conveyor belt 13 and the first conveyor roller 21 contact the bottom surface and the top surface of the panel, respectively, and are driven in the same direction. The roller pressing mechanism and the driving pulley 11 are driven by the same driving mechanism 4.
[0026] In this embodiment, when the panel is transported on the belt conveyor mechanism 1, the first conveyor roller 21 above the belt conveyor mechanism 1 contacts the top surface of the panel. The conveyor belt 13 and the first conveyor roller 21 provide co-directional transmission for the panel. On the one hand, the support plate 3 continuously arranged between the driving pulley 11 and the driven pulley 12 supports the panel. Compared with the structure supported by rollers, the panel is subjected to a more uniform support force and can withstand greater polishing pressure without breaking. On the other hand, the cleaning water during the polishing process has an adsorption effect on the panel and the conveyor belt 13, making it less likely for the panel to move or become misaligned on the conveyor belt 13. In addition, the roller pressing mechanism and the driving pulley 11 are driven by the same drive mechanism 4, resulting in good consistency in the transmission pace between the top and bottom surfaces of the panel and good positioning and transmission effect. These factors all contribute to improving polishing accuracy and are particularly suitable for processing small-sized panels.
[0027] The conveying mechanism in this embodiment is applied to a panel polishing machine. In this embodiment, the first conveyor roller 21 and the conveyor belt 13 form a conveying channel during panel polishing. A preset distance is provided between two adjacent first conveyor rollers 21 so that the grinding head of the panel polishing machine can extend between the two adjacent first conveyor rollers 21 to polish the panel surface.
[0028] Preferably, the support plate 3 is tangent to the top of the driving pulley 11 and the driven pulley 12, which can prevent the transmission belt 13 from deforming due to the pressure of the panel, and thus the panel is supported more evenly.
[0029] In this embodiment, the drive mechanism 4 can be a geared motor, which is fixed to the frame 5. To enable the same drive mechanism 4 to drive the first transmission roller 21 and the drive pulley 11 of the belt transmission mechanism 1, this embodiment provides a first transition shaft 6 and a second transition shaft 7 on the frame 5. The first transition shaft 6 and the second transition shaft 7 are rotatably mounted on the frame 5 via bearings. The first transition shaft 6 has a first gear 61 and a first intermediate pulley coaxially mounted on it, and the second transition shaft 7 has a second gear 71 and a second intermediate pulley set coaxially mounted on it. The first gear 61 meshes with the second gear 71. One end of the drive pulley 11 has a power input pulley set 111, and one end of the first transmission roller 21 has a first transmission pulley 211. The drive mechanism 4, the power input pulley set 111, and the first intermediate pulley are sequentially connected in a driving transmission manner, and the second intermediate pulley set is connected in a driving transmission manner to the first transmission pulley 211. A power output sprocket is provided on the power output shaft of the geared motor. This power output sprocket is connected to the sprocket on the power input wheel assembly 111 via a transmission chain, thereby enabling the operation of the drive pulley 11 and its transmission belt 13. Since the first gear 61 on the first transition shaft 6 meshes with the second gear 71 on the second transition shaft 7, the rotation directions of the first intermediate wheel on the first transition shaft 6 and the second intermediate wheel assembly on the second transition shaft 7 are opposite. In this embodiment, at least two sprockets are coaxially provided on the power input wheel assembly 111. Another sprocket on the power input wheel assembly 111 is connected to the first intermediate wheel on the first transition shaft 6 via a transmission chain, achieving reverse power transmission through the first gear 61 and the second gear 71. The first transmission wheel 211, connected to the second intermediate wheel assembly on the second transition shaft 7 via a transmission chain, drives the first transmission roller 21 to rotate in the opposite direction to the drive pulley 11. This allows the transmission belt 13 and the first transmission roller 21 to achieve co-directional transmission of the panel while in contact with the bottom and top surfaces of the panel, respectively.
[0030] To improve the polishing effect, the roller pressing mechanism in this embodiment also includes a cleaning mechanism. The cleaning mechanism includes a second transmission roller 22, a third transmission roller 23, an upper brush roller 24, and a lower brush roller 25. The second transmission roller 22 is positioned above the third transmission roller 23, and the upper brush roller 24 is positioned above the lower brush roller 25. The upper brush roller 24 is positioned between two adjacent second transmission rollers 22, and the lower brush roller 25 is positioned between two adjacent third transmission rollers 23. A transmission channel for panel cleaning is formed between the second transmission roller 22 and the third transmission roller 23, and between the upper brush roller 24 and the lower brush roller 25.
[0031] The second transmission roller 22 and the third transmission roller 23 rotate in opposite directions, and the upper brush roller 24 and the lower brush roller 25 rotate in opposite directions. The upper brush roller 24 rotates in the opposite direction to the second transmission roller 22, and the lower brush roller 25 rotates in the opposite direction to the third transmission roller 23. That is, the upper brush roller 24 rotates in the same direction as the third transmission roller 23, and the lower brush roller 25 rotates in the same direction as the second transmission roller 22.
[0032] In this embodiment, the first transmission roller 21, the second transmission roller 22, the third transmission roller 23, the upper brush roller 24, and the lower brush roller 25 are all provided with bearing slides a at both ends. The frame 5 is provided with a sliding groove that is adapted to the bearing slides a and extends in the vertical direction. The bearing slides a corresponding to the first transmission roller 21, the second transmission roller 22, and the upper brush roller 24 are provided with compression springs b at the top, and the top of the compression springs b is provided with adjusting nuts c that abut against them. The distance between the first transmission roller 21 and the transmission belt 13, the distance between the second transmission roller 22 and the third transmission roller 23, and the distance between the upper brush roller 24 and the lower brush roller 25 can all be adaptively adjusted according to the panel thickness. The compression spring b is sleeved on the adjusting rod, and the adjusting rod is provided with an adjusting nut c. The adjusting nut c abuts against the top of the compression spring b. By changing the position of the adjusting nut c on the adjusting rod, the pressure of the compression spring b on the bearing slide a can be adjusted, thereby adjusting the pressure applied to the panel by the first transmission roller 21, the second transmission roller 22, or the upper brush roller 24, which is suitable for grinding and cleaning panels of different thicknesses.
[0033] The cleaning mechanism can be located at the input end of the conveyor belt 13 to clean the panel surface before polishing; or it can be located at the output end of the conveyor belt 13 to clean the panel surface after polishing; or cleaning mechanisms can be located at both the input and output ends of the conveyor belt 13. In this embodiment, a pre-cleaning mechanism A is preferably located at the input end of the conveyor belt 13, and a re-cleaning mechanism B is located at the output end of the conveyor belt 13.
[0034] In this embodiment, both the pre-cleaning mechanism A and the re-cleaning mechanism B include the aforementioned second transmission roller 22, third transmission roller 23, upper brush roller 24, and lower brush roller 25. Since the surface of the panel after polishing generally contains more dust and impurities, this embodiment sets the number of upper brush roller 24 and lower brush roller 25 in the re-cleaning mechanism B to be more than that in the pre-cleaning mechanism A.
[0035] In this embodiment, the second intermediate rotating wheel group is provided with at least three coaxially arranged sprockets. Each sprocket on the second intermediate rotating wheel group is used to drive at least one of the first transmission roller 2, the second transmission roller 22, and the lower brush roller 25 to rotate. Specifically, one end of the second transmission roller 22 is provided with a second drive wheel 221, and one end of the lower brush roller 25 is provided with a lower brush drive wheel 251. In this embodiment, the first drive wheel 211, the second drive wheel 221, and the lower brush drive wheel 251 are all arranged on the same side of the frame 5. The lower brush drive wheel 251 is drivenly connected to the second intermediate rotating wheel group, and the second drive wheel 221 is drivenly connected to the second intermediate rotating wheel group.
[0036] One end of the drive pulley 11 is provided with a power input pulley set 111, and the other end is provided with a power output pulley set 112. Multiple sprockets are coaxially arranged on the power output pulley set 112. The power output pulley set 112 is used to drive the third transmission roller 23 and the upper brush roller 24 to rotate. One end of the third transmission roller 23 is provided with a third drive wheel 231, and one end of the upper brush roller 24 is provided with an upper brush drive wheel 241. In this embodiment, the third drive wheel 231 and the upper brush drive wheel 241 are both located on the same side of the frame 5, and the upper brush drive wheel 241 is drivenly connected to the power output pulley set 112, and the third drive wheel 231 is drivenly connected to the power output pulley set 112.
[0037] Preferably, in this embodiment, the active pulley 11 is positioned close to the output end of the transmission belt 13, that is, a larger number of re-cleaning mechanisms B are positioned close to the active pulley 11 for the upper brush roller 24 and lower brush roller 25, and a smaller number of pre-cleaning mechanisms A are positioned close to the driven pulley 12 for the upper brush roller 24 and lower brush roller 25.
[0038] To reduce the use of long chains and improve the reliability of synchronous transmission, in this embodiment, the lower brush roller 25 of the pre-cleaning mechanism A is connected to one of the second transmission wheels 221 via a transmission chain. All the second transmission wheels 221 of the pre-cleaning mechanism A are connected via transmission chains. The second transmission wheel 221 adjacent to the first transmission wheel 211 is connected to the first transmission wheel 211 via a transmission chain. A first tension wheel 8 is provided between the second transmission wheel 221 and the first transmission wheel 211. Furthermore, in this embodiment, the upper brush transmission wheel 241 of the pre-cleaning mechanism A is connected to one of the third transmission wheels 231 via a transmission chain. All the third transmission wheels 231 of the pre-cleaning mechanism A are connected via transmission chains. The third transmission wheel 231 closest to the power output wheel assembly 112 is connected to the power output wheel assembly 112 via a transmission chain. A second tension wheel 9 is provided between the power output wheel assembly 112 and the third transmission wheel 231 located at the input end of the transmission belt 13.
