Detailed description of the invention
A kind of composite members automatic piecing arrangement, see Fig. 1 ~ Fig. 4: it comprises upper bracket 1, it is (not shown in FIG. that upper bracket 1 is parallel to below composite members sizing material feed track, belong to existing mature structure), the below of upper bracket 1 is provided with framework architecture 2, the arranged beneath of frame structure 2 has two pressure rollers 3, two pressure rollers 3 are arranged before and after the direction of below composite members sizing material feed track, the two ends of each pressure roller 3 are supported on the lower end location structure 5 of corresponding swing arm 4 respectively, the middle and upper part of the swing arm 4 of correspondence position is respectively arranged with rotating shaft 6, the two ends of rotating shaft 6 are supported on the both sides correspondence position of frame structure 2 respectively, swing arm 4 corresponding to two pressure rollers 3 is arranged in opposite directions, the top of two swing arms 4 is connected by pressure roller cylinder 7, the two ends of pressure roller cylinder 7 are fastenedly connected the top of two swing arms 4 respectively.
Pressure roller 3 specifically comprises bearing 8, square shaft 9 of seven band square holes, the bearing 8 of seven band square holes is series at respectively on square shaft 9 and forms pressure roller 3, the two ends evagination of square shaft 9, be fastenedly connected in the mounting groove 10 that the evagination two ends of square shaft 9 are installed in the location structure 5 of the respective side of swing arm 4 respectively, when this roller structure makes to install, location is convenient, guarantees that location fast, accurately.
When pressure roller 3 roll extrusion composite members sizing material, owing to likely there is slippage, so increase one deck belt 11 between pressure roller 3 and composite members sizing material, and need about one fine motion space due to pressure roller 3, stretching only by belt 11 cannot be dealt with problems, so increase the length required for fine motion of offsetting spring structure counteracting belt in one end fixation side of belt 11, therefore design following structure:
Location arrangements between the two ends of upper bracket 1 has belt 11, the upper-lower position of the rear and front end of frame structure 2 is furnished with guide roller 12 respectively, belt 11 walks around frame structure 2 along guide roller 12 respectively, the lower roll surface of two pressure rollers 3 press-fits the upper surface of the belt 11 in correspondence position respectively, the wherein end position that belt 11 corresponds to upper bracket 1 is provided with offsetting spring structure, and offsetting spring structure guarantees that belt is in tension;
Offsetting spring structure comprises linear springs 13, belt fastening structure 14, belt fastening structure 14 is fastenedly connected two straight-line guidance bars 15 be arranged in parallel, straight-line guidance bar 15 is set with linear springs 13 after running through positioning pedestal 16, pressing plate 17 is fastenedly connected after two straight-line guidance bars 15 protrude from positioning pedestal 16, linear springs 13 is mounted on pressing plate 17 respectively, positioning pedestal 16, positioning pedestal 16 is anchored on upper bracket 1, the inner face of belt fastening structure 14 and positioning pedestal 16 leaves free gap, free gap is left in the outer face of pressing plate 17 and positioning pedestal 16, the rectilinear motion of straight-line guidance bar 15 under the pressure effect of linear springs 13 is guaranteed in two gaps, belt is in tension to guarantee to drive belt to guarantee by belt fastening structure 14.
Above specific embodiment of the utility model has been described in detail, but content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within this patent covering scope.
