Wheel is constantly in the state away from the first belt pulley, by adjusting the position of the second pull bar, changes the elastic force of extension spring it is possible to adjust
The tensile force of whole belt, makes belt be in suitable tensioning state, and when belt occurs lax, extension spring pulls portable plate to the left,
Second belt pulley away from the first belt pulley, realizes the auto-tensioning of belt automatically.
Further, described first pull bar is soket head cap screw, and described support bar and the second pull bar are bleed screw, described
The end of thread that second pull bar is located on the left of support bar is provided with adjusting nut, and the two ends of described steel wire rope are provided with lock, described
Steel wire rope passes through lock and forms the cranse for entangling the first pull bar and extension spring.Using conventional parts, structure is simple, is easy to
Assembling and maintenance, reduces cost.
The automatic-type belt tensioning device of infinitely variable speeds blender of the present utility model, adjusts the center of belt pulley using extension spring
Away from, and then realize the auto-tensioning of belt, its structure is simple, is easy to assemble and safeguards, with low cost, is particularly suitable for little space
Infinitely variable speeds blender.

Specific embodiment
With reference to the accompanying drawings and detailed description content of the present utility model is described in further details.
Embodiment:
The infinitely variable speeds blender of the present embodiment employs a kind of stepless change disclosed in prior art (cn105508530a)
Fast drive mechanism, it utilizes balance pivot technology, rotates gear change hand lever, drives speed change support to move axially along the axis of guide, activity
Gearing shift fork accompanies and is synchronized with the movement, under balance pivot effect, the first and second dynamic half wheel simultaneous linkage displacement reducings, thus in fact
Existing infinitely variable speeds.
Refer to shown in Fig. 1 and Fig. 2, a kind of automatic-type belt tensioning device of infinitely variable speeds blender, including frame 1, peace
The first belt pulley 2 being contained in frame 1 right side, the portable plate 3 being arranged on frame 1 left side, the second belt being arranged on portable plate 3
Wheel 4 and belt 5, the side of described portable plate 3 and frame 1 are hinged, and described hinged side is the first belt pulley 2 and the second belt
Take turns the either side of 4 line of centres both sides, the couple positioned opposite in the hinged side of portable plate 3 has the first pull bar 6, with the first pull bar 6
Rolling wheel support 7 is provided with the frame 1 of homonymy, rolling wheel support 7 is provided with roller 8, roller 8 is located at the left side of the first pull bar 6,
The frame 1 on rolling wheel support 7 right side is additionally provided with support bar 9, described support bar 9 is provided with can second the drawing of left and right adjusting
Bar 10, described automatic-type belt tensioning device also includes extension spring 11 and steel wire rope 12, one end of described extension spring 11 and the second pull bar
