The threaded rod A242 is connected to the rotating shaft of the lifting motor 241. The end of the threaded rod A242 away from the lifting motor 241 is movably connected to the mounting frame A210 via a threaded block. The material conveying structure 2 is used to transport long steel materials. The interior of the housing 1 has an attraction layer, the main material of which is sponge, and the surface has an anti-pollution layer to reduce the noise generated by the device.

[0026] The housing 1 has an end-face polishing structure 4 inside. There are two sets of end-face polishing structures 4 arranged opposite each other. One set of end-face polishing structures 4 is located inside the upper end cover 101. The lower end face of the other set of end-face polishing structures 4 is equipped with an electrical box 5 and is fixedly connected to the housing 1. The electrical box 5 is equipped with a power control module 6. The end-face polishing structure 4 includes a mounting frame B410, an end-face polishing roller 420 and a polishing lifting motor 430.

At the same time, coarse polishing and fine polishing wheels can be installed in sequence according to the feeding direction, thereby improving polishing efficiency and quality.

[0027] When in use, after the long steel material is pushed onto the conveying structure 2, the drive motor 211 will drive the three conveying rollers 220 to feed the raw material into the device. At this time, the auxiliary support rod 230 and the auxiliary support wheel 232 will adjust the angle of the workpiece entering the device. The operator can start the polishing lifting motor 430 through the control panel, and place the two sets of end face polishing rollers 420 onto the end face of the workpiece. The rollers will be driven by the motor to rotate and polish the workpiece. The auxiliary support rod 230 and the auxiliary support wheel 232 of the conveying structure 2 at the other end will adjust the position of the workpiece so that it can be aligned with the conveying roller 220 at the exit and transported out of the device to complete the polishing.

[0028] During this process, the lifting height of the lifting mechanism 240 can be adjusted through the control panel, thereby facilitating the adjustment of the height of the raw material structure 2 and making it convenient for loading different workpieces.

[0029] Example 2: During the use of the device, polishing of I-beam steel is also required. The polishing effect of its side is limited by the horizontal polishing device of the device, resulting in an unsatisfactory polishing effect. At the same time, dust particles are often generated during the polishing process, causing serious environmental pollution. Therefore, the following improvements are made.

[0030] like Figure 2 As shown, side polishing wheel structures 3 are provided on both sides of the mounting bracket B410 and above the auxiliary support rod 230. There are four side polishing wheel structures 3 in total, arranged in pairs opposite each other at the opening of the housing 1.

The side of the side mounting bracket 310 away from the polishing wheel 320 is equipped with a polishing motor 330. The upper end face of the polishing motor 330 and the inner side of the side mounting bracket 310 are connected to the polishing wheel 320 by a belt. The side mounting bracket 310 has an upper mounting plate 311 on the side away from the polishing wheel 320. The upper mounting plate 311 is connected to the electric push rod A340 by fixing bolts. The side of the electric push rod A340 away from the upper mounting plate 311 is fixedly connected to the housing 1. A lower mounting plate 312 is provided below the upper mounting plate 311. One end of the lower mounting plate 312 is fixedly connected to the side mounting bracket 310. The lower end of the electric push rod A340 has a limit baffle. One end of the limit baffle is fixedly connected to the housing 1. The inner side of the limit baffle has a groove and is slidably connected to the lower mounting plate 312. The side polishing wheel structure 3 is used to polish the side of the workpiece. On one side of the side polishing wheel structure 3, and above the material conveying structure 2, a downward deceleration structure 7 is provided. The downward deceleration structure 7 includes a mounting plate 710, an electric push rod B720, and a deceleration wheel 730.

The upper end face of the brake pad 722 has a spring rod B721 connected to the electric push rod B720. The downward deceleration structure 7 is used to slow down the movement of the workpiece within the device. The polishing wheel 320 can be replaced with polishing wheels of different shapes according to processing needs to adapt to the shape of the steel material for polishing.

[0031] When in use, commands can be input to the electric push rod A340 via the control panel. At this time, the polishing wheel 320 can polish the side of the workpiece, and can also make certain directional adjustments to the workpiece, so that it can perform polishing operations more efficiently and accurately. The downward deceleration structure 7 can apply downward force to both ends of the workpiece after the workpiece enters the device, which can restrict the movement of the workpiece. At the same time, the brake pad 722 can effectively reduce the influence of multiple polishing wheels on the movement of the workpiece.

[0032] like Figure 3 As shown, inside the housing 1, between the side polishing wheel structure 3 and the end face polishing structure 4, there is a dust removal fan 8. One end of the dust removal fan 8 is fixedly connected to the housing 1 via a fixing plate and faces the electrical box 5. A baffle is provided between the electrical box 5 and the lifting mechanism 240, forming a dust storage trough 9 for collecting powder particles generated during workpiece polishing. The inner side of the dust storage trough 9 can prevent dust collection bags, which can improve dust recovery efficiency and ensure the normal operation of the device.

[0033] When in use, after the end face polishing structure 4 completes polishing, some dust will float inside the device, while some dust will adhere to the surface of the workpiece. At this time, the dust removal fan 8 blows air onto the end face of the workpiece to clean it. Excess dust will fall into the dust storage tank 9. At this time, it can be used with a collection bag to collect the dust, thereby reducing environmental pollution and ensuring the normal operation of the device and the polishing quality.

[0034] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
