Strip billet tensioning device of V-shaped belt cloth wrapping machine

Abstract

The invention discloses a strip billet tensioning device of a V-shaped belt cloth wrapping machine. The strip billet tensioning device comprises a rack, wherein one side of the rack is fixedly connected with a first rotary motor and a second rotary motor; the output end of the first rotary motor is fixedly connected with a first connecting rod; the first connecting rod passes through the rack; oneend of the first connecting rod is rotatably connected with a drive wheel through a rotary shaft; one side of the drive wheel is equipped with a driven wheel; the center of one side of the driven wheel is fixedly connected with a connecting block; a second connecting rod is arranged on the inner cavity of the connecting block in a sleeving mode; strip billets are arranged on the drive wheel and the driven wheel; one side of the driven wheel is equipped with a gear; the gear is rotatably connected with a third connecting rod through a rotary shaft; and the third connecting rod passes through the rack. The strip billet tensioning device of the V-shaped belt cloth wrapping machine is simple in structure, is easy in operation, is relatively low in manufacturing cost, is easily popularized, and has a wide application prospect.

[0002] Rubber V-belt is the most widely used type of transmission belt. Cloth wrapping operation is an important process in the production of rubber V-belt. The rubber V-belt wrapping operation is mainly to wrap the belt core through the cloth wrapping device after the primer is covered. Adhesive cloth of a certain specification, the existing wrapping machine includes a belt blank tensioning device, the belt blank tensioning device includes a tensioning cylinder, a driving motor and a pulley, the belt pulley includes a driving wheel and a driven wheel, and the driving motor drives the driving wheel to rotate, The driven wheel is connected with the tensioning cylinder, the driving wheel and the driven wheel are equipped with installation ring grooves, and the strip blanks are respectively installed in the installation ring grooves of the driving wheel and the driven wheel, and the tension cylinder drives the driven wheel to move, and the belt blank is tightened. It is clamped in the installation ring groove. When the wrapping is completed, the tensioning cylinder moves in reverse to take out the V-belt after the wrapping is completed; but sometimes the V-belt is still locked with the installation ring groove after the wrapping is completed, It is laborious to remove the belt from the installation ring groove, which affects the production efficiency, which is far from meeting the current people's requirements for this product. Therefore, how to design a belt blank tensioning device for a V-belt wrapping machine has become our current solution. The problem
