In frame；The cutter assembly includes disc cutter, threaded rod and axle sleeve, and the threaded rod is fixedly welded in frame, and position
In the surface of backing roll, inner hole of shaft sleeve wall car internal thread, axle sleeve is threadedly coupled with threaded rod, and the disc cutter passes through double
It is rotatably installed in thrust ball bearing on axle sleeve, cutter assembly shares two groups；Also fixed cutoff tool, the cut-out cutter spacing on axle sleeve
After disc cutter, and it is coplanar with cross section in disc cutter.
As further program of the utility model：Material cutting-off mechanism is also installed, the material cutting-off mechanism includes in the frame
Cam coaxial mounted with backing roll, push rod and crush-cutting knife, the push rod is slidably arranged in the slideway in frame, described
Crush-cutting knife is fixed in the end of push rod.
As further program of the utility model：Stage clip is arranged outside the push rod.
As further program of the utility model：The position relative with crush-cutting knife sets grooving in the frame.
As further program of the utility model：The guide roller being oriented to waste material is also installed in the frame.
As further program of the utility model：Runner is fixedly installed on the axle sleeve.
Compared with prior art, the beneficial effects of the utility model are：In the utility model, disc cutter passes through screw thread knot
Structure adjusting position, the trimming position different to PET sheet is realized, ensure that trimming will not be excessive, also will not be very few, and pass through setting
Cutoff tool, ensure that rim charge can be completely severed, it is ensured that trimming process is smoothed out.
Brief description of the drawings
Fig. 1 is main structure diagram of the present utility model.
Fig. 2 is side structure schematic view of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1~2, in the utility model embodiment, a kind of continuous-flow type PET sheet trimming mechanism, including：Backing roll
6th, frame 7 and cutter assembly, the backing roll 6 are arranged in frame 7；The cutter assembly includes disc cutter 3, threaded rod 5
With axle sleeve 2, the threaded rod 5 is fixedly welded in frame 7, and in the surface of backing roll 6, the inner hole wall car system of axle sleeve 2
Screw thread, axle sleeve 2 are threadedly coupled with threaded rod 5, and the disc cutter 3 is rotatably installed in axle sleeve 2 by double-direction thrust ball bearing 4
On, cutter assembly shares two groups, and by rotary axle box 2, the position of disc cutter 3 can be adjusted axially along backing roll 6, so as to
It is adjusted at any time in production process, ensures that disc cutter 3 is in better position, make the waste material of excision will not be excessive, also will not
It is very few；Also fixed cutoff tool 15, the cutoff tool 15 (press sheet material direction of feed) after being located at disc cutter 3 on axle sleeve 2, and with circle
Cross section is coplanar in disk cutting knife 3, if disc cutter 3 fails to cut off part rim charge, and cutoff tool 15 is in cutting gap, then
The part for throwing away adhesion can be cut off, completely disengage rim charge.
