[0022] For the specific embodiment, the vertical frame 102 and the base 101 are fixedly connected and located on the top of the base 101; the guide rail 103 and the vertical frame 102 are fixedly connected and located on the inner side of the vertical frame 102; two support components 104 are located on both sides of the guide rail 103, and the support component 104 comprises a nut block 108, a mounting frame 109 and a transmission wheel 110; the nut block 108 and the guide rail 103 are slidingly connected and located on the side edge of the guide rail 103; the mounting frame 109 and the nut block 108 are fixedly connected and located on the side edge of the nut block 108; the transmission wheel 110 and the mounting frame 109 are rotatably connected and located on the side edge of the mounting frame 109; the polishing belt 105 is sleeved on both side edges of the two transmission wheels 110; the motor 106 and the mounting frame 109 are fixedly connected, and the output end of the motor 106 and the transmission wheel 110 are fixedly connected and located on the side edge of the mounting frame 109; the driving component 107 is arranged on the side edge of the vertical frame 102. The base 101 is used for supporting the vertical frame 102. When the surface of the plastic toy is polished, the motor 106 is started, the motor 106 drives the transmission wheel 110 connected thereto to rotate, so that the polishing belt 105 can rotate, and the worker can make the surface of the plastic toy to be polished contact with the polishing belt 105, and polish the burrs on the surface of the plastic toy through the rotating polishing belt 105; when the polishing belt 105 is relaxed after long-time use, resulting in insufficient tension on both sides of the polishing belt 105, the worker can control the driving component 107 to drive the two nut blocks 108 to move away from each other, the guide rail 103 provides guidance for the two nut blocks 108, and the two nut blocks 108 drive the two mounting frames 109 and the two transmission wheels 110 to move away from each other, the two transmission wheels 110 pull the polishing belt 105, so that the polishing belt 105 maintains appropriate tension, thereby avoiding the problem that the polishing effect of the burrs on the plastic toy is reduced due to insufficient tension of the polishing belt 105. The utility model solves the problem that the existing burr polishing device for plastic toy production cannot adjust the tension on both sides of the polishing belt 105 when the tension on both sides of the polishing belt 105 is insufficient, thereby reducing the polishing effect of the burrs on the plastic toy.

[0023] The lower support 111 is fixedly connected with the vertical frame 102 and located at the side of the vertical frame 102; the outer ring of the bearing 112 is fixedly connected with the lower support 111 and located at the side of the lower support 111; the upper support 113 is fixedly connected with the vertical frame 102 and located at the side of the vertical frame 102; the bidirectional screw rod 114 is fixedly connected with the inner ring of the bearing 112 and respectively threaded with two nut blocks 108 and located at the side of the bearing 112, and the end of the bidirectional screw rod 114 away from the bearing 112 penetrates through the upper support 113. The lower support 111 and the bearing 112 jointly support the bidirectional screw rod 114, the upper support 113 is provided with a through hole matched with the bidirectional screw rod 114, so that the bidirectional screw rod 114 can rotate on the upper support 113, the two ends of the bidirectional screw rod 114 are provided with external threads with opposite screw directions, the two nut blocks 108 are located at the two ends of the bidirectional screw rod 114 with opposite screw directions, the staff can make the two nut blocks 108 move away from each other along the guide rail 103 by rotating the bidirectional screw rod 114 in the positive direction, the two nut blocks 108 drive the two mounting frames 109 and the two transmission wheels 110 to move away from each other, and the two transmission wheels 110 pull the polishing belt 105 to keep the polishing belt 105 at a proper tension.

[0024] Secondly, the holding piece 115 is arranged at the end of the bidirectional screw rod 114 away from the bearing 112. The staff can hold the holding piece 115 to facilitate the rotation of the bidirectional screw rod 114, so as to adjust the position of the transmission wheel 110.

[0025] Meanwhile, the supporting rod 116 is fixedly connected with the bidirectional screw rod 114 and located at the end of the bidirectional screw rod 114 away from the bearing 112; the locking rod 117 is slidably connected with the supporting rod 116 and penetrates through the supporting rod 116; the handle 118 is fixedly connected with the locking rod 117 and located at the side of the locking rod 117; the upper support 113 is provided with a plurality of locking holes 119, and the plurality of locking holes 119 are respectively located at the side of the support.
