Embodiment 1
Shown in Fig. 1-5,
A kind of for automatic cutting bed film covering device again, comprise underframe, transmission device, bracing or strutting arrangement and overlay film circular shaft mechanism, described overlay film circular shaft mechanism is fixed on the underframe by bracing or strutting arrangement, transmission device is installed on the bracing or strutting arrangement, it is characterized in that described overlay film circular shaft mechanism is connected with transmission device synchronously by synchronous band.Described underframe comprises crossbeam 1 and leg 10, and the both sides, lower end of described crossbeam 1 are provided with two legs 10 that keep beam balance, are respectively arranged with two connecting plates 9 and 13 on the left and right sides leg 10.
Described bracing or strutting arrangement comprises support bar 5 and overlay film circular shaft support 6, described overlay film circular shaft support 6 one ends are fixed in the overlay film circular shaft mechanism, the other end is fixed on the described leg 10, described support bar 5 one ends are fixed on the middle part of overlay film circular shaft support 6, the other end is fixed on the crossbeam 1, overlay film circular shaft mechanism by about two cover bracing or strutting arrangements and underframe fix.The place that links to each other with overlay film circular shaft support 6 on the described support bar 5 is provided with elongated slot, and the connecting key on the overlay film circular shaft support is free to slide in elongated slot.Because support bar 5 can be regulated relative position with overlay film circular shaft support 6 by elongated slot, can make the overlay film height of whole film covering device again that certain adjustable range is arranged.
Transmission mechanism 4 left sides connect right connecting plate 9, and the right connects right overlay film circular shaft support 6, and left overlay film circular shaft support 6 is connected with left connecting plate 13 by six rib pillars 11.Described overlay film circular shaft mechanism 7 is installed on two overlay film circular shaft supports 6, links to each other by tectorial paper with square tube simultaneously, and square tube is fixed on the square tube support of cutting out a front end.
Described overlay film circular shaft mechanism is made up of aluminum pipe 7, lining, synchronous pulley 7.5, bearing and axle etc.Described left and right sides lining is installed in the two ends of aluminum pipe 7, left and right sides lining is to insert under the situation of aluminum pipe 7 heating, because of according to principle of expanding with heat and contracting with cold, can shrink and hold tightly automatically lining after aluminum pipe 7 coolings, in addition because the dynamic effect of right-hand member of axle, therefore after right lining 7.6 is worked good with aluminum pipe 7, process through drilling machine, aluminum pipe 7, lining 7.6 and 7.4 3 parts of driving shaft are all punched by being located by alignment pin.Right lining 7.6 is equipped with a driving shaft 7.4, clamping a synchronous pulley 7.5 in the middle of driving shaft 7.4 and the lining 7.6, synchronous pulley 7.5 adopts key joint with driving shaft 7.4, the right-hand member of driving shaft 7.4 is equipped with two bearings 7.3, the inner ring of bearing cooperates with right axle 7.1, and right axle 7.1 and driving shaft 7.4 are all finished by jump ring 7.2 with the location of bearing 7.3.Two bearings are equipped with in lining 7.11 inside, a left side, the inner ring of bearing cooperates with left side axle 7.7, and locate by jump ring, the left end of left side axle 7.7 is with a regulating wheel 7.10, regulating wheel 7.10 also connects by the form of key joint with left side axle 7.7, the left end of regulating wheel 7.10 is equipped with spring 7.9, and spring 7.9 is by the pressure of adjusting nut 7.8 controllable adjustable wheel 7.10 with left lining 7.11, and this has also determined overlay film circular shaft self to exist suitable frictional force when rotating.
Described transmission mechanism is made up of bearing block 4.2, end ring, connecting axle 4.1, synchronous pulley and bearing etc.End ring 4.6 is equipped with in the centre that 4.5, two deep groove ball bearings of two deep groove ball bearings are equipped with in described bearing block 4.2 inside, and respectively there are an end ring and hole in the outer end of bearing with back-up ring 4.3.Big synchronous pulley 4.8 of bearing block outer termination and a small synchronous pulley 4.7, linear guides at crossbeam 1 is equipped with synchronous band tooth bar in addition, this is with tooth bar just in time can cooperate with big synchronous pulley 4.8 synchronously, connecting axle 4.1 begins to pass from right-hand member, pass right overlay film circular shaft support 6 earlier, pass end ring then and cooperate with deep groove ball bearing 4.5, pass right connecting plate 9 at last and by nut check.
Concrete operation principle of the present utility model is as follows:
One end of tectorial paper is bonded on the square tube, and its other end is bonded on the overlay film circular shaft, and tectorial paper slightly is longer than the sanction of cutting out the bed X-axis and is cut scope, so tectorial paper twists on the overlay film circular shaft.At the front end of cutting out bed two square tube supports are housed, make the support fixation of square tube.Before carrying bed and starting working, according to the real work needs, adjust square tube at the height of square tube support, adjust the relative position between overlay film circular shaft support and the support bar simultaneously, make the height of overlay film circular shaft mechanism satisfy work requirements.After the sanction bed is started working, the process of cutting along with sanction, crossbeam moves toward the X-axis positive direction, synchronous band tooth bar engagement on the big synchronous pulley 4.8 of transmission mechanism and the linear guides of crossbeam 1 begin to rotate, so the small synchronous pulley above the transmission mechanism 4.7 and bearing block 4.2 etc. also begins to rotate, because synchronously with 8 transmission, synchronous pulley 7.5 in the overlay film circular shaft mechanism rotates, and drives the rotation of overlay film circular shaft and discharges tectorial paper, makes the tectorial paper tensioning.When sanction cut finish after, vavuum pump quits work, and moves to the X-axis initial point along with cutting out a crossbeam, again by above-mentioned transmission, drives the overlay film circular shaft and rotates, and has played the effect of receipts tectorial papers.
It will be recognized by those skilled in the art, under the prerequisite that does not depart from protection scope of the present invention, can carry out various modifications, variation and combination to above-mentioned embodiment, and think that this modification, variation and combination are within the scope of originality thought.
