[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figures 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0029] The effect of the solution in claim 1 is as follows: Figure 1 , 2 As shown in Figure 4: A burr grinding device includes a support frame 101, on which a belt conveyor 102 is mounted. These are all prior art and therefore require no further explanation. A guide plate 110 is provided on one vertical side of the support frame 101. The guide plate 110 guides the workpiece to be ground, which is placed on the belt conveyor 102, thus preventing the workpiece from shifting during transport. The guide plate 110 is bolted to one vertical side of the support frame 101, allowing for easy disassembly and assembly when the guide plate 110 needs to be repositioned or maintained. A mounting plate 103 is provided on the support frame 101 and on the vertical surface of the guide plate 110. The mounting plate 103 provides stable support for the components on it. The mounting plate 103 is bolted to the upper part of the mounting column, so that the mounting plate 103 and its components can be easily disassembled and assembled when replacement or maintenance is required. Two lifting grooves 104 are provided through the vertical surface of the mounting plate 103. The two lifting grooves 104 allow the position adjustment of the two sliders 403 and their components, thereby preventing the sliders 403 from tilting when moving.

[0030] The lifting grooves 104 can be cut into the mounting plate 103 using a cutting machine, making the lifting grooves 104 easy to manufacture. Lifting blocks 105 are slidably connected within both lifting grooves 104. The lifting blocks 105 allow the transmission rod 106 and its components to rise and fall accordingly, facilitating the adjustment of the heights of the first rotating cylinder 107 and the second rotating cylinder 108. Therefore, it is convenient to adjust the height of the first rotating cylinder 107 according to the workpiece specifications, and it also allows for tensioning of the sanding belt 109. Each of the two lifting blocks 105 is equipped with a drive mechanism, and both sets of drive mechanisms... Used for height adjustment of the corresponding lifting blocks 105, each of the two lifting blocks 105 is rotatably connected to a transmission rod 106. The transmission rod 106 is set so that the rotation of the transmission rod 106 can drive the various parts on it to move accordingly. One end of the transmission rod 106 is rotatably connected to the lifting block 105 through a bearing, so that the transmission rod 106 will not jam when rotating. A first rotating cylinder 107 is connected to the outer wall of the transmission rod 106 near the guide plate 110. The rotation of the first rotating cylinder 107 can drive the sanding belt 109 to rotate, and then the workpiece can be polished by the rotation of the sanding belt 109.

[0031] The first rotating cylinder 107 is fixedly connected to the outer wall of the transmission rod 106, which makes the connection structure of the first rotating cylinder 107 more stable. This allows the rotation of the first rotating cylinder 107 to move the sanding belt 109. A second rotating cylinder 108 is connected to the outer wall of the transmission rod 106 on the side away from the guide plate 110. The second rotating cylinder 108 provides guidance and support for the sanding belt 109. The second rotating cylinder 108 is fixedly connected to the outer wall of another transmission rod 106, making the connection structure more stable and providing guidance to one end of the sanding belt 109. The diameter of the first rotating cylinder 107 is larger than that of the second rotating cylinder 108. The diameter of the first rotating cylinder 107 is large, which increases the contact area and allows for rapid grinding of the workpiece. A sanding belt 109 is provided on the outer wall of the first rotating cylinder 107 and the second rotating cylinder 108. The sanding belt 109 can be moved to quickly grind the workpiece conveyed on the belt conveyor 102. The sanding belt 109 is sleeved on the outer wall of the first rotating cylinder 107 and the second rotating cylinder 108. The first rotating cylinder 107 rotates and the second rotating cylinder 108 guides the sanding belt 109 to move, thereby grinding the surface of the workpiece.

[0032] In use, the starting motor 202 causes the first rotating drum 107 to rotate, and the belt conveyor 102 is started, causing the sanding belt 109 mounted on it to rotate. The second rotating drum 108 can guide the other side of the sanding belt 109. When the sanding belt 109 rotates, the workpiece is placed on the belt conveyor 102 with the guide plate 110 close to it. At this time, the workpiece will be conveyed to the sanding belt 109 by the belt conveyor 102. The rotating sanding belt 109 can quickly grind the surface of the workpiece. After one side of the workpiece is ground, it can be stored and then the other side can be ground again, and so on. Alternatively, after one side is ground, it can be removed from the belt conveyor 102 and the other side can be ground again. Therefore, when grinding and polishing long rectangular workpieces, there is no need to perform frequent clamping and disassembly operations on the workpiece, thereby improving the overall production efficiency.

[0033] The effect of the solution in claim 2 is as follows: Figure 3 , 4 As shown: A fixing frame 201 is provided on the vertical surface of the lifting block 105 near the guide plate 110. The fixing frame 201 provides support for the motor 202, preventing the output shaft of the motor 202 from rotating on its own. The fixing frame 201 is bolted to the vertical surface of one of the lifting blocks 105, making it easy to disassemble and install when replacement or maintenance is required. The motor 202 is mounted on the fixing frame 201. The rotation of the output shaft of the motor 202 drives the transmission rod 106 on the first rotating cylinder 107 to rotate accordingly. The motor 202 is bolted to one side of the fixing frame 201, making it easy to disassemble and install when maintenance or replacement is required. The output shaft of the motor 202 is connected to one end of the transmission rod through a coupling, so that the rotation of the output shaft of the motor 202 drives the transmission rod 106 on the first rotating cylinder 107, thereby causing the various components on it to rotate accordingly.

[0034] The effect of the solution in claim 3 is as follows: Figure 3 , 4As shown: Each drive mechanism includes a threaded rod 301 mounted on the upper part of the lifting block 105. The threaded rod 301 can be rotated by the driven gear 302, thereby driving the threaded rod 301 to move up and down. The threaded rod 301 is fixedly connected to the upper part of the lifting block 105, so that when the driven gear 302 rotates and drives the threaded rod 301 to move up and down, the threaded rod 301 will not rotate, thus improving the stability of the movement of the lifting block 105. The driven gear 302 is mounted on the upper part of the mounting plate 103 at the position corresponding to the threaded rod 301. The driven gear 302 is connected to the threaded rod 301 through a threaded engagement. The driven gear 302 can be rotated, thereby driving the threaded rod 301 to move up and down. A driving gear 303 is mounted on one side of the driven gear 302. The driving gear 303 meshes with the driven gear 302. The driving gear 303 can be rotated, thereby driving the driven gear 302 to rotate accordingly.

[0035] Furthermore, locking can be achieved through the driven gear 302 engaging with the threaded rod 301, and then through the driven gear 302 engaging with the driving gear 303, thereby further improving the stability of the lifting block 105 and its components. Each driven gear 302 and each driving gear 303 are connected to the upper part of the mounting plate 103 through a thrust bearing, ensuring that the driven gear 302 and driving gear 303 will not jam during rotation. An adjusting rod 304 is provided on one side of the upper part of the driving gear 303. The adjusting rod 304 allows the operator to manually adjust the driving gear 303, thus enabling the driving gear 303 to rotate while saving manufacturing costs. The adjusting rod 304 is fixedly connected to the upper part of each driving gear 303, making its connection structure more stable.

[0036] In use, the height of the lifting block 105 supported by the first rotating cylinder 107 can be adjusted according to the specifications of the workpiece, making it suitable for grinding workpieces of various specifications. The height of the lifting block 105 supported by the second rotating cylinder 108 can be adjusted according to the usage and width of the sanding belt 109, thereby adjusting the tension of the sanding belt 109 and improving the grinding effect on the workpiece. During adjustment, simply hold the adjusting rod 304 and rotate the drive gear 303. By rotating the drive gear 303 forward or backward, the height of the corresponding lifting block 105 can be adjusted. Therefore, it is suitable for grinding workpieces of various specifications and can also adjust the tension of the sanding belt 109.

[0037] The effect of the solution in claim 4 is as follows: Figure 4 , 5As shown: A guiding mechanism is provided on the vertical surface of the mounting plate 103 near the belt conveyor 102, between the guide plate 110 and the first rotating drum 107. This guiding mechanism ensures that the workpiece being conveyed on the belt conveyor 102 is guided and limited, preventing the workpiece to be ground from shifting during conveying and avoiding shifting due to high-speed friction during grinding. The guiding mechanism includes a fixing frame 401 on the mounting plate 103, providing stable support for all components. The fixing frame 401 is bolted to the mounting plate 103. The fixed frame 401 and its components are designed to be easily disassembled and reassembled when maintenance or replacement is required. A telescopic rod 402 is provided on the upper part of the fixed frame 401. The telescopic rod 402 allows the push rod of the telescopic rod 402 to move up and down, which in turn drives the slider 403 connected to the end of the push rod and its components to move up and down accordingly. The telescopic rod 402 is bolted to the upper part of the fixed frame 401, which makes it easy to disassemble and reassemble when maintenance or replacement is required. The telescopic rod 402 can be an electric telescopic rod 402, which can save costs and facilitate operation.

[0038] A slider 403 is connected to the end of the push rod of the telescopic rod 402. The slider 403 supports the components on it and allows the slider 403 and its components to move up and down. The slider 403 is fixedly connected to the end of the push rod of the telescopic rod 402, making the connection structure more stable. A lifting rod 404 is rotatably connected to one vertical surface of the slider 403. The lifting rod 404 supports the limiting post 405 and allows the limiting post 405 to rotate when it limits the workpiece, thus preventing damage to the workpiece surface. Furthermore, it can prevent the workpiece from jamming when limiting the position. The lifting rod 404 is rotatably connected to the vertical surface of the slider 403 via a bearing, so that the lifting rod 404 will not jam when rotating. A limit post 405 is provided on the outer wall of the lifting rod 404. The limit post 405 can be used to hold the side of the workpiece that needs to be ground, thereby preventing the workpiece from tilting during the grinding or conveying process. The limit post 405 is fixedly connected to the outer wall of the lifting rod 404, making its connection structure more stable.

[0039] The effect of the solution in claim 5 is as follows: Figure 5As shown: A spring 501 is provided between the inner wall of the fixed frame 401 and the slider 403. The spring 501 can improve the stability of the limiting post 405, the lifting rod 404 and the slider 403 when limiting the workpiece, and further avoid the instability when limiting the workpiece. One end of the spring 501 is fixedly connected to the inner wall of the fixed frame 401, and the other end of the spring 501 is fixedly connected to the upper part of the slider 403, so that its connection structure is more stable.

[0040] The effect of the solution in claim 6 is as follows: Figure 5 As shown: Guide blocks 602 are provided on both vertical surfaces of the slider 403. The guide blocks 602 work with the guide grooves 601 to limit the slider 403, thereby preventing the slider 403 from deviating during its up and down movement. The guide blocks 602 are fixedly connected to the vertical surfaces of the slider 403, making the connection structure more stable. The fixed frame 401 has guide grooves 601 at the positions of the two guide blocks 602. The guide grooves 601 allow the guide blocks 602 to slide within them, further improving stability. The guide grooves 601 and the fixed frame 401 can be cut using a cutting machine during manufacturing, which facilitates manufacturing and improves the overall structural stability. The two guide blocks 602 are slidably connected within their respective guide grooves 601, thus limiting the guide blocks 602 within the guide grooves 601.

[0041] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
