compression springs

71,72, two left and

right briquettings

81,82, last roll shaft 91, lower roller shaft 92, lower roller 1, flat belt 2 and a plurality of bearing.

As Fig. 1,2,3, shown in 4, a left side, right supporting base 11, have on 12 and be used for making a roller left side,

right slide block

41,42 chutes that move, a left side,

right tensioning plate

21,22 are " L " type, the end of L type one end has the chute that roll shaft 91 is moved, the bearing of supporting lower roller shaft 92 is equipped with in the end of the other end, the middle part of the other end has the through hole that allows lower roller 1 pass, last roll shaft 91, lower roller shaft 92, lower roller 1 two ends respectively have and are used for limiting " V " type groove (4) that flat belt 2 walks, and the both sides of flat belt 2 are designed to and last roll shaft 91, lower roller shaft 92, " V " type projection that lower roller 1 groove matches.

Shown in Fig. 1,2,3,4, the end at two ends has the last roll shaft 91 of " V " type groove, be bearing on the bearing of the left and

right slide block

51,52 of roll shaft, the left and

right slide block

51,52 of last roll shaft is embedded in respectively in the chute of an end of the left and

right tensioning plate

21,22 of " L " type that has chute, its bottom is bearing on the chute bottom surface of left and

right tensioning plate

21,22 by a

compression spring

71,72 respectively, and its top is past by the clamp screw screw top that is fixed on the left and right briquetting 81,82 respectively.

Shown in Fig. 1,2,3,4, two ends have the lower roller shaft 92 of " V " type groove 4, are bearing on the two bearings of the other end of the left and

right tensioning plate

21,22 of " L " type, and its two ends are sealed by the left and right sides bearing cap shim 61,62 of lower roller shaft respectively; The lower roller 1 that the end at two ends has " V " type groove 4 passes left and right supporting

base

11,12 1 ends of " L " type hole at middle part partially, be bearing in respectively on the bearing in the left and right slide block of

roller

41,42, the left and

right slide block
