Abstract
The utility model discloses an automatic film-folding diameter adjusting device, which mainly comprises a motor mounting frame, a support frame, a motor, a guide rod, a screw, a sliding block and an electronic sensing device. The motor mounting frame is arranged opposite to the support frame, the motor is arranged on the motor mounting frame, and the two ends of the guide rod are fixed on the motor mounting frame and the support frame; and the sliding block is connected with the guide rod in a sliding way and is screwed with the screw, and the electronic sensing device is arranged on the sliding block. Four detection sensors are adopted to detect data on a plastic film, the positions of the detectors can be adjusted through the driving servo motor, and the actual width of the film can be measured and calculated automatically and can be adjusted according to the set width value. Since the width of the film is always detected and can be adjusted at any time, the width of the plastic film cannot deviate beyond the error range and the product quality can be effectively improved.
Description
Technical field
The utility model relates to a kind of plastic tape production equipment, particularly relates to a kind of film folding footpath adjusting device automatically.
Background technology
In the production process of plastic sheeting, the film thickness that stretches out for blown film need carry out a control constantly, makes it be in the scope of an equilibrium, guarantees that its width is in the error range.At present, control belongs to an experience control for the width of film, needs workman's timing detection to come the width of MEASUREMENTS OF THIN, can not accomplish to detect constantly, and make adjustment.
The utility model content
The purpose of this utility model is to provide a kind of can adjust thin-film width at any time, effectively guarantee that thin-film width is in the automatic adjusting device in film folding footpath in the error range.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of film folding footpath adjusting device automatically, and it mainly is made up of motor installing rack, bracing frame, motor, guide rod, screw mandrel, sliding shoe, electronic inductor; Described motor installing rack and bracing frame are oppositely arranged, and motor is installed on the motor installing rack, and the two ends of guide rod are fixed on motor installing rack and the bracing frame; One end of described screw mandrel is connected with motor output shaft by shaft coupling, and the other end of screw mandrel is rotating to be connected on the bracing frame; Described sliding shoe slips on guide rod and with screw mandrel and is spirally connected, and electronic inductor is installed on the sliding shoe.
Described motor installing rack, motor, screw mandrel, sliding shoe, electronic inductor all constitute by two; Described two motor installing racks are oppositely arranged, and bracing frame is arranged on the centre of two motor installing racks; Described two motors are installed in respectively on two motor installing racks, and the output shaft of two motors is connected with screw mandrel by shaft coupling respectively; Described two sliding shoes slip respectively on guide rod and with two screw mandrels and are spirally connected, and two electronic inductors are installed on two sliding shoes respectively and are oppositely arranged.
Described electronic inductor is made up of two detection inductors that abut against together.
After adopting such scheme, the utility model comprises two electronic inductors, servomotor, screw mandrel etc., and each electronic inductor all can detect and judges that plastic sheeting is whether in its detection range plastic film.Because the utility model can detect the data whether inductor detects plastic sheeting by four, driving servomotor adjusts the position of checkout gear, after the adjustment, can can calculate the developed width of film according to the pitch system of the number of turns of actual rotation and screw mandrel automatically, according to the width value of setting thin-film width be adjusted again.By the utility model, the width of film is in the process that a quilt detects constantly, can adjust at any time according to the width constantly of film, guarantees that the plastic sheeting width can not be offset to outside the error range, effectively raises the quality of product.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is an axonometric drawing of the present utility model;
Fig. 2 is the axonometric drawing that the utility model detects plastic sheeting;
Fig. 3 is the partial top view that the utility model detects plastic sheeting;
Fig. 4 is the schematic diagram that the utility model detects plastic sheeting.
The specific embodiment
As shown in Figure 1, the utility model is an a kind of film folding footpath adjusting device automatically, and it mainly is made up of two motor installing racks 11,12, bracing frame 2, two motors 31,32, guide rod 4,51,52, two sliding shoes of two rhizoid bars 61,62, two cover electronic inductors 71,72.
Described two motor installing racks 11,12 are oppositely arranged, and bracing frame 2 is arranged on the centre of two motor installing racks 11,12; Described two motors 31,32 are installed in respectively on two motor installing racks 11,12, and the output shaft of two motors 31,32 is connected with screw mandrel 51,52 by shaft coupling 8 respectively, and motor 31,32 adopts servomotor.
Described two sliding shoes 61,62 slip respectively on guide rod 4 and with two screw mandrels 51,52 and are spirally connected, and two cover electronic inductors 71,72 are installed on two sliding shoes 61,62 respectively and are oppositely arranged.
Described electronic inductor 71 is made up of two detection inductors 711,712 that abut against together; Equally, electronic inductor 72 is made up of two detection inductors 721,722 that abut against together.
As Fig. 2-shown in Figure 4, operation principle of the present utility model:
1, control mainly is to blowing in the process of drawing for the width of plastic sheeting 10, and the air quantity that adopts during to blown film is controlled, and reaches the purpose of adjusting plastic sheeting 10 width.
2, in process of production, plastic sheeting 10 can be folded pressing by man-like shelf after being blown and pulling out, and is fed on the ensuing production line by a tension force rubber roll then.
3, two cover electronic inductors 71,72 are arranged on the tension force rubber roll.Plastic sheeting 10 from the tension force rubber roll through out-of-date, if two marginal positions of the normal plastic sheeting 10 of width can be detected by the inner electronic inductors 712,721 in the two cover electronic inductors 71,72 respectively.
When 4, detection induction installation 711,712 or 721,722 does not all detect or all detects, induction installation can be under the driving of motor initiatively the marginal position of searching for film, measure the developed width of film, if the width of measuring is littler than setting value, the then automatic tonifying Qi of inflation film manufacturing machine meeting, increase air-blowing quantity, increase the width of plastic sheeting 10; If the developed width of measuring is bigger than setting value, then inflation film manufacturing machine can be cooled down automatically, reduces air-blowing quantity, reduces the width of plastic sheeting 10.
5, in the course of work of inflation film manufacturing machine, be to be in a state that detects constantly to the width of plastic sheeting 10, be in all the time in the scope of an equilibrium so can effectively guarantee the width of plastic sheeting 10.
In addition, if the utility model has only a cover electronic inductor, and maintain static.Can there be drawback in so words, and width that might film is in predetermined scope, but the deviation that position that may film occurs, and cause electronic inductor all not detect or have all detected, and cause and make mistakes.
Emphasis of the present utility model just is: two groups of electronic inductors are set.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
