Especially after oxidation treatment after wire drawing, the added value of the product is greatly improved. Make products more competitive in the market.

Triangular planar wire drawing machine is a kind of wire drawing machine, and the abrasive belt will deviate during operation. Therefore, the inclination angle of the upper abrasive belt wheel needs to be adjusted. The existing upper abrasive belt wheel has a complicated structure for adjusting the deflection, and the operation is cumbersome, and the adjustment can only be performed after stopping the machine; and the adjusting part is arranged at the rear position of the upper abrasive belt wheel. That is to say, it is necessary to stand behind the triangular plane wire drawing machine to carry out the adjustment process. After each adjustment, it is necessary to go to the front of the triangular plane wire drawing machine and start the machine to see if the abrasive belt still deviates. It often needs to go back and forth several times before adjusting, which is time-consuming and laborious, and brings inconvenience to daily use.

One end of the screw rod is screwed into the screw hole and pressed through the through hole. On the shaft plate frame, the adjusting handwheel is arranged on the other end of the screw mandrel.

As an improvement of the utility model, it also includes a locking handwheel, and the center of the locking handwheel is provided with a screw hole matching the screw rod.

As an improvement of the utility model, the wheel shaft is welded on the shaft plate.

As an improvement of the utility model, the bearing assembly includes two deep groove ball bearings, and the two deep groove ball bearings are symmetrically sleeved on both ends of the wheel shaft.

As an improvement of the utility model, the tensioning wheel is an aluminum alloy wheel body.

The beneficial effects of the utility model are: the utility model has an ingenious and reasonable structural design, and when adjustment is required, the adjustment hand wheel should be turned clockwise or counterclockwise, so that the screw rod will protrude or retract the through hole, and then adjust the shaft accordingly. The turning angle of the plate relative to the shaft plate frame is to adjust the upward or downward inclination angle of the tensioning wheel accordingly, so as to achieve the purpose of adjusting the abrasive belt without deviation. When the adjustment is appropriate, turn the locking handwheel and press it on the On the wheel shaft, the screw rod is locked to prevent the screw rod from rotating in the circumferential direction due to the vibration of the tensioner wheel. The work stability is good, and the operator is standing in front of the tensioner wheel to adjust, without stopping the machine, and can be real-time Check the effect of adjusting the abrasive belt, the operation is simple and convenient, save time and effort, and the overall structure is simple, compact, novel, low cost, easy to implement, and conducive to widespread popularization and application.

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
