Furthermore, in the scheme, the end of the axle 30, which penetrates through the cover plate 29, is connected with the lifting bolt 92 in a threaded manner, so that a user can directly lift the lifting bolt 92 to extract the guide wheel 26, and the lifting device is more convenient and faster.

The supporting seat 21 is further provided with a bearing seat 35, the bearing seat 35 is located between the two bearing seats 25, the bearing seat 35 is further provided with a brush roller 36, and the width direction of the brush roller 36 is the same as the width direction of the steel plate conveying channel 18. In addition, as a preferred embodiment, the roller line of the brush roller 36 is disposed at an included angle with the horizontal plane. It is easy to understand that the contact between the outer roll surface of the brush roll 36 and the side wall of the steel plate 99 is similar to line contact, if the brush roll 36 is placed parallel to the horizontal plane, only one line area of the side wall of the steel plate 99 can be brushed, and the side wall part of the side wall of the steel plate 99 adjacent to the upper plate surface and the lower plate surface is not brushed cleanly. And the roller line of the brush roller 36 is arranged at an included angle with the horizontal plane, so that the side wall of the steel plate 99 can be comprehensively brushed.

Specifically, the first elastic element includes a spring 39, a fixing plate 40 is disposed on the base 20, a fixing rod 41 is disposed on a side wall of the supporting seat 21 close to the rear end face of the base 20, one end of the fixing rod 41 far away from the supporting seat 21 penetrates through the fixing plate 40, the spring 39 is sleeved on the fixing rod 41, and two ends of the spring 39 respectively abut against the fixing plate 40 and the supporting seat 21.

Since the steel plate 99 may be skewed during the transportation of the steel plate 99, the center line of the steel plate 99 is not located on the center line of the base 19 or the steel plate transportation path 18. If the base 20 is still located at the center line of the steel plate conveying channel 18 and the original width of the steel plate 99, the guide wheel 26 on one side of the base 20 cannot be attached to the side wall of the steel plate 99, and the guide wheel 26 on the other side collides with and interferes with the side wall of the steel plate 99.

In the present embodiment, since the width of the steel plate 99 to be processed is known and the width of the steel plate conveying passage 18 is also known, when the center line of the steel plate 99 and the center line of the steel plate conveying passage 18 are assumed to coincide, a standard interval between the steel plate 99 and the non-moving guide wheel 26, which is a predetermined interval, can be obtained. When the steel plate 99 is conveyed into the steel plate conveying passage 18, the driving assembly drives the base 20 to slide relative to the base 19 so that the two bases 20 approach each other. At this time, only the preset stroke is required to be larger than the preset interval, even if the steel plate 99 is deflected, the guide wheel 26 can contact with the side edge of the steel plate 99, and the support seat 21 can be retracted because the moving distance of the guide wheel 26 exceeds the interval between the guide wheel 26 and the side edge of the steel plate 99. In the process that the steel plate 99 presses the guide wheel 26 to drive the supporting seat 21 to slide towards the rear end face of the base 20, the supporting seat 21 drives the fixing rod 41 to move backwards relative to the fixing plate 40, the spring 39 on the fixing rod 41 is compressed, and the spring 39 always gives a reset acting force to the supporting seat 21, so that the guide wheel 26 on the supporting seat 21 is always attached to the side wall of the steel plate 99 in the steel plate conveying channel 18 for guiding.

The user need only turn the sleeve 42 so that the sleeve 42 is away from or close to the rear end face of the support base 21. After the sleeve 42 is adjusted to make the sleeve 42 approach the supporting seat 21, the deformation amount of the spring 39 increases when the steel plate 99 presses the guide wheel 26 to slide the supporting seat 21 to the rear end surface of the base 20. After the sleeve 42 is adjusted to make the sleeve 42 away from the supporting seat 21, when the steel plate 99 presses the guide wheel 26 to drive the supporting seat 21 to slide towards the rear end surface of the base 20, the deformation amount of the spring 39 is reduced. Thereby through the deformation volume of adjusting spring 39 apron 29 spring 39 acts on the restoring force of supporting seat 21, avoid guide pulley 26 and the too inseparable steel sheet 99 that leads to of the laminating of steel sheet 99 side to be difficult to carry, also avoid guide pulley 26 and the separation of steel sheet 99 side to lead to unable realization direction spacing effect. And in order to facilitate the knob adjustment of the sleeve 42, a knob handle 43 is arranged on the end of the sleeve 42 far away from the supporting seat 21. As shown in fig. 7, a baffle 44 is vertically disposed on the base 20, and the baffle 44 is located between the front end surface of the base 20 and the support base 21. When the steel plate 99 is conveyed in the steel plate conveying channel 18, the guide wheel 26 loses the limit of the steel plate 99, the restoring force of the spring 39 forces the supporting seat 21 to move towards the steel plate conveying channel 18, and the supporting seat 21 abuts against the baffle 44, so that the supporting seat 21 is prevented from sliding out of the base 20 due to the elastic force of the spring 39.

In this embodiment, the second elastic member acts on the bearing seat 35. Specifically, as shown in fig. 11 and 16, the second elastic member is a tension spring 45, a tension spring seat 46 is disposed on the support seat 21, one end of the tension spring 45 is connected to the tension spring seat 46, and the other end of the tension spring 45 is connected to the bearing seat 35. Since the brush roller 36 is retracted to be aligned with the guide wheel 26 during the feeding process of the base 20, the steel plate 99 presses the guide wheel 26 to drive the supporting seat 21 to slide towards the rear end surface of the base 20, and at this time, the tension spring 45 is stretched and deformed.

In order to facilitate the assembly and disassembly of the tension spring 45, a first hook 47 is arranged on the tension spring seat 46, a second hook 48 is arranged on the bearing seat 35, and two ends of the tension spring 45 are respectively hooked and connected with the first hook 47 and the second hook 48.

During the conveying of the steel plate 99, the brush rollers 36 on both sides continuously brush the side edges of the steel plate 99. The brush roll 36 includes a roll core, and abrasive filaments wrapped around the roll core to form a brush layer, wherein the abrasive filaments are stick-shaped resin substrates containing rigid abrasive particles and have a long strip-shaped cylindrical structure. In the process of brushing, the abrasive wires are gradually shortened, and the roller diameter of the brush roller 36 is continuously reduced. And when the roller diameter of the brush roller 36 is continuously reduced, a gap will be formed between the brush roller 36 and the side wall of the steel plate 99, but because the tension spring 45 is stretched and deformed, when a gap will be formed between the brush roller 36 and the side wall of the steel plate 99, the restoring force of the tension spring 45 will immediately pull the bearing seat 35 to feed towards the direction of the side edge of the steel plate 99, the gap formed between the brush roller 36 and the side wall of the steel plate 99 is automatically compensated, and the brush roller 36 is forced to be always attached to the side wall of the steel plate 99 to realize uninterrupted grinding and brushing.

Preferably, the tension spring seat 46 can slide relative to the support seat 21 along the width direction of the support seat 21 in the present embodiment.
