As shown in fig. 1-3, the utility model provides a sanding belt quick detach mechanism of equipment of polishing, including organism 1, organism 1 includes casing 2 and drive arrangement 3, and above-mentioned drive arrangement 3 passes through the frame 22 to be fixed inside casing 2, is formed with the working chamber 21 that supplies drive arrangement 3 function in the inner space of casing 2 to make the operator when polishing the work piece, the piece, dust, the waste material of production all concentrate inside casing 2, convenient unified collection processing. The driving device 3 comprises a motor 31, and a connecting shaft 32 is arranged on the motor 31; a grinding wheel 4 is arranged on the connecting shaft 32, a driven wheel 5 is correspondingly arranged on the grinding wheel 4, and an abrasive belt 6 is tightly arranged on the peripheries of the grinding wheel 4 and the driven wheel 5 in a surrounding manner; when the motor 31 is energized to operate, the connecting shaft 32 drives the grinding wheel 4 to operate, and the abrasive belt 6 also drives the driven wheel 5 to operate under the action of the grinding wheel 4.

As shown in fig. 2-5, a take-up unit 700 is also disposed in the body 1 and cooperates with the driven wheel 5 to operate together; the above-described slackening device 700 is used for more convenient replacement of the sanding belt 6 and for keeping the sanding belt 6 always tightly wound around the periphery of the grinding wheel 4 and the driven wheel 5. Specifically, the tensioner 700 includes a push-pull unit 710, an adjustment unit 720, and a guide shaft 730. The guide shaft 730 is fixedly installed at one side of the housing 22, and the adjusting unit 720 is installed on the guide shaft 730 and horizontally movable. The push-pull unit 710 is provided with a hand lever 711 extending from the interior of the body 1 through the housing 2, a pull block 712 is screwed to the end of the hand lever 711, a moving block 713 is hinged to one end of the pull block 712, and the moving block 713 is hinged to a connecting block 714. The adjusting unit 720 includes a fixing seat 721 fixedly connected to the connecting block 714 and a baffle 725 hinged to the pulling block 712, the fixing seat 721 is clamped with a connecting rod 722, and one end of the connecting rod 722 is fixedly connected to the driven wheel 5; an adjusting seat 723 is screwed below the fixed seat 721, the adjusting seat 723 is of a frame structure, mounting holes corresponding to the guide shafts 730 are formed above the adjusting seat 723 and the baffle 725, a spring 726 is clamped between the adjusting seat 723 and the baffle 725, and the adjusting seat 723 and the baffle 725 clamp the spring 726 and are sleeved on the guide shafts 730 through the mounting holes in a penetrating manner; the baffle 725 is fixedly coupled to the guide shaft 730 by bolts. Mounting holes are correspondingly formed below the adjusting seat 723 and the baffle 725, bearings 727 are correspondingly arranged between the mounting holes in the frame of the adjusting seat 723, and a fixing rod 724 penetrates through the mounting holes and the bearings 727, so that the baffle 725 is movably connected with the adjusting seat 723. The fixing rod 724 penetrates through one end of the baffle 725 to be provided with threads and is fixed through an adjusting nut 729, a limiting block 728 is arranged at the other end of the fixing rod 724, the limiting block 728 is fixed on the fixing rod 724 through a bolt, the limiting block 728 is used for limiting the maximum distance of the adjusting seat 723 moving in the opposite direction relative to the baffle 725, and the adjusting nut 729 is used for adjusting the distance between the baffle 725 and the adjusting seat 723. In addition, in order to increase the production efficiency, a manufacturer can arrange at least one group of the grinding wheel 4 and the driven wheel 5, the periphery of which is tightly wound with the abrasive belt 6, and at least one group of the tightening device 700 which is matched with the grinding wheel to operate, so that one device can be used for two operators to carry out grinding construction simultaneously.

When the abrasive belt 6 is seriously worn and needs to be replaced, an operator cuts off the power of the motor 31, pulls the hand lever 711 towards the direction of the grinding wheel 4, and the baffle 725 is fixed on the guide shaft 730 and cannot move; at this time, the adjusting seat 723 installed below the fixing seat 721 is affected by the external force of the hand lever 711, breaks through the resilience of the spring 726, and compresses the spring 726, so that the fixing seat 721 drives the driven wheel 5 to move horizontally towards the direction of the grinding wheel 4, and the abrasive belt 6 is loosened and removed and replaced. After the abrasive belt 6 is replaced, as long as the handle rod 711 is loosened, at this time, the influence of external force is eliminated, the spring 726 pushes the adjusting seat 723 back under the action of the self-resilience force, so that the driven wheel 5 horizontally moves in the opposite direction of the grinding wheel 4, and finally the adjusting seat 723 stays on the limiting block 728, so that the abrasive belt 6 surrounds the peripheries of the driven wheel 5 and the grinding wheel 4 and is tensioned again.

In addition, when the length of use of abrasive belt 6 is increased, a slack state occurs, so that the clearance between it and grinding wheel 4 and driven wheel 5 increases, resulting in a decrease in friction force during operation and a decrease in stability. At this time, since the baffle 725 is fixed to the guide shaft 730, only the adjusting nut 729 on the fixing rod 724 needs to rotate in the opposite direction of the adjusting seat 723 to be loosened, so that the distance between the adjusting seat 723 and the baffle 725 is increased, the adjusting seat 723 is horizontally pushed outwards under the influence of the elastic tension of the spring 726, and the driven wheel 5 is driven by the adjusting seat 723 to move in the opposite direction of the grinding wheel 4. Finally, the abrasive belt 6 is again tightened around the grinding wheel 4 and the driven wheel 5. The arrangement mode of the take-up unit 700 enables an operator to replace the abrasive belt 6 without disassembling any part, and the operation is very simple; and abrasive belt 6 is always kept taut by adjusting nut 729 in conjunction with the elastic tension of spring 726, preventing a slack condition of abrasive belt 6 from occurring due to long-term operation.

The utility model provides a sanding belt quick-dismantling mechanism of a grinding device, which is characterized in that a take-up unit 700 is arranged to be matched with a driven wheel 4 to operate, so that the take-up unit 700 can drive or rebound the driven wheel 4, and an operator can quickly replace a sanding belt 6 by pulling a push-pull unit without disassembling any parts; and, only by rotating the adjusting nut 729, the loose abrasive belt 6 can be kept taut on the outer periphery of the driven wheel 5 and the grinding wheel 4. The arrangement mode simplifies the replacement process of the abrasive belt 6, improves the production efficiency, enables the abrasive belt 6 to be always kept in a tight state and not to loosen, not only improves the use efficiency of the abrasive belt 6, but also enables the equipment to be more stable and reliable during operation.
