In order to solve the above-mentioned technical problem, the technical solution of the utility model is to provide a kind of bolt and screws adjustable tensioner
Mechanism, including rotary wheel frame, runner are set on rotary wheel frame, and runner is connect with runner driving motor by runner drive belt；It is special
Sign is：The rotary wheel frame is respectively arranged on the left side and the right side an expansion tightening wheel fixing bracket, and the left and right ends of Pulley shaft are respectively arranged on
On the expansion tightening wheel fixing bracket of the left and right sides；Belt pulley be set to Pulley shaft centre position and fixation, and belt pulley with it is described
The outer side contacts of runner drive belt；Adjusting bolt fixed plate is equipped among expansion tightening wheel fixing bracket, adjusting bolt, which passes through, adjusts spiral shell
Bolt fixed plate simultaneously withstands Pulley shaft.
Preferably, the left and right ends of the Pulley shaft are fixed on a left side by an expansion tightening wheel fixing bracket nut check respectively
On the expansion tightening wheel fixing bracket of right both sides.
Preferably, the expansion tightening wheel fixing bracket is equipped with slotted hole, and the left and right ends difference of Pulley shaft is movably
In the slotted hole on the expansion tightening wheel fixing bracket of both sides.
Preferably, the belt pulley with the contact surface of runner drive belt on a parallel face.
Preferably, the position relationship of the adjusting bolt and Pulley shaft meets：When adjusting bolt is rotated to tightening direction,
Pulley shaft is promoted to the direction of belt pulley and runner drive belt contact surface side.
The utility model is mounted on belt by the expansion tightening wheel fixing bracket nut adjustment on the expansion tightening wheel fixing bracket of left and right
The balance of belt wheel face above wheel shaft makes belt pulley with runner drive belt contact surface on a parallel face.Utilize a left side
Right two adjusting bolts are tightened, and make the Pulley shaft that adjusting bolt top withstands or so uniform force, along expansion tightening wheel fixing bracket
The advance of slotted hole track horizontal homogeneous above makes runner drive belt be in more tight state, when improving belt transmission
Efficiency.
Device provided by the utility model overcomes conventional apparatus, and because left and right unbalance stress causes belt to be cut, oblique, rotation is unilateral
The deficiency of friction, tension mechanism both ends are individually fixed on the rotary wheel frame of left and right, and belt pulley is installed on the centre position of Pulley shaft
Left and right uniform force is screwed when adjusting by two nuts in left and right, belt pulley and belt contacts face is made to always remain as one simultaneously
A plane contact improves efficiency when belt transmission, extends the service life of belt, while also having prevented belt abrasion production
Pollution of the raw powder to working environment.
