As shown in fig. 2 and 3, the supporting assembly 5 is configured to include two fixed shafts 9 rotatably connected to the rotating disc 4, the abrasive belt 6 is tightly wound around the two fixed shafts 9, and a supporting motor 10 for driving one of the fixed shafts 9 to rotate is fixedly connected to an end surface of the rotating disc 4 facing away from the fixed shafts 9. Therefore, the supporting motor 10 can drive the fixing shaft 9 connected with the supporting motor 10 to rotate when being started, the abrasive belts 6 tightly wound on the two fixing shafts 9 can rotate under the driving of the fixing shaft 9, the two abrasive belts 6 are tightly abutted to the metal bar under the driving of the turntable 4 to polish the metal bar, and the two abrasive belts can rotate around the two fixing shafts 9 to polish the metal bar under the driving of the supporting motor 10, so that the polishing effect of the abrasive belts 6 on the metal bar is further improved.
As shown in fig. 2 and 3, it is considered that after long-time use, the tension of the abrasive belt 6 may be reduced, so that the abrasive belt is difficult to abut against the metal bar, and the polishing effect of the metal bar is affected; the supporting component 5 can also include a regulating wheel 11 connected to the rotary table 4, a waist-shaped regulating hole 12 is formed in the rotary table 4, a regulating rod 13 capable of sliding along the regulating hole 12 is arranged in the regulating hole 12 in a penetrating mode, the regulating wheel 11 is connected to the regulating rod 13 in a rotating mode and located on the inner edge of the abrasive belt 6, the rotary table 4 deviates from the end face of the abrasive belt 6 and is fixedly connected with an electric push rod 14, and the electric push rod 14 and the regulating hole 12 are arranged in parallel and are fixedly connected to the regulating rod 13 in an output end mode. Therefore, when the electric push rod 14 is started, the adjusting rod 13 can be driven by the electric push rod to drive the adjusting wheel 11 to slide along the adjusting hole 12, so that the effect of adjusting the tightness of the abrasive belt 6 by adjusting the position of the adjusting wheel 11 is achieved, and the abrasive belt 6 can stably abut against a metal bar material for a long time to polish the metal bar material; meanwhile, the worker can also loosen the abrasive belt 6 by starting the electric push rod 14 to drive the adjusting wheel 11 to be separated from the abrasive belt 6, so that the abrasive belt 6 can be conveniently replaced.
As shown in fig. 2 and 4, it is considered that the adjusting wheel 11 is pressed against the abrasive belt 6 and receives a reaction force from the abrasive belt 6, and then the reaction force is transmitted to the output end of the electric push rod 14 through the adjusting rod 13, so that the electric push rod 14 is easily damaged; a plurality of T-shaped sliding grooves 16 parallel to the adjusting holes 12 are formed in the rotary table 4, one end, far away from the adjusting wheel 11, of the adjusting rod 13 is fixedly connected with a limiting plate 15, a T-shaped sliding block 17 matched with the sliding grooves 16 is connected to a fixed block on the limiting plate 15, and the sliding block 17 is connected in the sliding grooves 16 in a sliding mode.

Thus, stopper 18 has the effect of limiting the position of abrasive belt 6, making it difficult for abrasive belt 6 to disengage from stationary shaft 9 under the action of external force, thereby further enhancing the stability of the connection between abrasive belt 6 and stationary shaft 9; meanwhile, when the abrasive belt 6 needs to be disassembled and replaced, the worker can firstly adjust the adjusting wheel 11 to be separated from the abrasive belt 6 to separate the abrasive belt 6, and then the check block 18 is disassembled from the fixed shaft 9 through the thread in the mode of rotating the check block 18, so that the worker can conveniently disassemble and replace the abrasive belt 6.
As shown in fig. 5, it is considered that, in the process of polishing the metal bar by using abrasive belt 6, there may be a situation that abrasive belt 6 is blocked or folded due to an excessively large offset distance, thereby affecting the polishing effect of abrasive belt 6 on the metal bar; the end face of the stop block 18 facing the rotary table 4 is connected with a first limiting ring 20 matched with the fixed shaft 9 through a plurality of first springs 19, and the first limiting ring 20 is sleeved on the outer edge of the fixed shaft 9; the end surface of the rotary table 4 facing the stop block 18 is connected with a second limiting ring 22 matched with the fixed shaft 9 through a plurality of second springs 21, the second limiting ring 22 is sleeved on the outer edge of the fixed shaft 9, and the abrasive belt 6 is positioned between the first limiting ring 20 and the second limiting ring 22. Therefore, when the abrasive belt 6 deviates under the action of external force, the first spring 19 or the second spring 21 on the deviation side is stressed to contract, and when the first spring 19 or the second spring 21 is stressed to contract, the elastic restoring force is transmitted to the abrasive belt 6 through the first limiting ring 20 or the second limiting ring 22, so that the abrasive belt 6 with the deviation can be restored to the initial position under the action of the elastic restoring force of the first spring 19 or the second spring 21, the effect of automatically correcting the abrasive belt 6 is achieved, and the stability of the abrasive belt 6 in the process of polishing the metal bar is further improved.
As shown in fig. 1 and 5, a wireless infrared sensor 41 for detecting a distance between the first limiting ring 20 and the second limiting ring 22 is further fixedly connected to an end surface of the first limiting ring 20 facing the second limiting ring 22, and a buzzer 42 linked with the wireless infrared sensor 41 is fixedly connected to the rack 1, when a detection value of the infrared sensor is greater than a preset safety value, that is, when the abrasive belt 6 has an excessive deviation, which causes the distance between the first limiting ring 20 and the second limiting ring 22 to be greater than the preset safety value, the support motor 10, the drive motor 23, the conveying motor 32, and the fan 39 are simultaneously stopped and the buzzer 42 triggers to generate a buzzer, so as to remind a worker to timely handle the abrasive belt 6 in an abnormal situation, thereby reducing the possibility that the metal bar is continuously polished in an abnormal situation of the abrasive belt 6, and affecting the polishing quality of the metal bar, and further improving the polishing effect of the abrasive belt 6 on the metal bar.
The implementation principle of the embodiment of the application is as follows: when the metal bar needs to be polished, a worker can start the hydraulic cylinder 35 to drive the two first conveying wheels 29 to move upwards, the metal bar is placed in the arc-shaped grooves 31 of the two second conveying wheels 30, the hydraulic cylinder 35 is started to drive the two first conveying wheels 29 to press downwards to enable the metal bar to be tightly abutted between the two first conveying wheels 29 and the two second conveying wheels 30, then the conveying motor 32 is started to drive the metal bar to move towards the direction of the discharge hole 3 of the rack 1, in the process that the metal bar moves along the discharge hole 3, the two abrasive belts 6 on the rotary table 4 can be tightly abutted on the metal bar under the driving of the rotary table 4 to rotate to polish the metal bar, meanwhile, the two abrasive belts 6 can rotate relative to the rotary table 4 under the driving of the supporting motor 10 to further polish the metal bar, the effect of automatically polishing the metal bar is achieved, time and labor are saved, and the degree of intelligence is high.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
