Coil taping machine
Technical field:
The present invention relates to a kind of coil manufacturing technology, particularly coil taping machine.
Background technology:
After coil molding, need on coil case, wrap up insulation mica tape, generally need more than ten layers of wrappings, workload is larger.Patent is 201020679038.3 utility model patent, discloses a kind of mica taping machine, includes pitch controlling organization, band mechanism and driving mechanism, and there are two band wheels in band mechanism.Although this belting machine has improved than the efficiency of manual band, but the problem existing is, after manually coil being placed in machine, manually the mica tape on two belt wheels is wound around after 2-3 circle on coil case, starter motor carries out band, when coil is during from left end bag to right-hand member head, also need repetition band repeatedly just can reach the required number of plies, due to the defect of equipment, coil can not move band by right-to-left, now needs two mica tapes to cut off, after coil is return, be wound into after coil 2-3 circle manual mica tape, starter motor carries out band again again.Therefore the efficiency of this belting machine is low.The patent No. is 200710171704.5, name is called the patent of invention of coil taping machine, this belting machine does not need the hand steered coil of holding in winding mica tape process, is automatically wound around, but still need to cuts off mica tape by machine, again make coil turn back to original position manual winding after mica tape 2-3 circle, the automatic band of starter motor, this automatic belting machine has not just needed hand-held coil in band process, and the raising of band efficiency is not obvious, but its price is up to hundreds thousand of units.
Summary of the invention:
The object of the invention is to provide the coil taping machine that a kind of band efficiency is high and price is low.
The technical scheme that realizes the object of the invention is, coil taping machine, comprise transmission mechanism, band sprocket wheel, belt wheel and pitch axle and back shaft, it is characterized in that: belt wheel one side on band sprocket wheel end face is at least provided with a rotating tape guide, described pitch axle is former and later two pitch axles, and the bottom of described forward and backward pitch axle is respectively equipped with a gear and engages with the gear of worm reduction gear output shaft respectively.The rotating tape guide of described belt wheel one side is two.
The present invention has band efficiency height and the low remarkable advantage of price compared with the prior art.
Brief description of the drawings:
Fig. 1 is structural representation of the present invention; Fig. 2 is the right side view of Fig. 1; Fig. 3 is coil belt wheel angle of inclination schematic diagram while being moved to the left; Fig. 4 is coil belt wheel angle of inclination schematic diagram while moving right; Fig. 5 be mica tape from belt wheel through guide wheel the tape transport schematic diagram to coil; Fig. 6 is bipatch through-drive principle schematic of the present invention.
Embodiment:
The present invention solves the defect that can not wrap continuously mica tape to coil that prior art exists, adopt following technical proposals to realize the task of not shutting down continuous bag mica tape through experiment, be provided with at band sprocket wheel 1 on the end face of belt wheel 2 and at least establish two rotating tape guides 10, the rotating tape guide of preferred plan is four, mica tape 9 is wrapped on coil 8 bodies through rotating tape guide from band wheel is released, now the angle of mica tape and coil is generally 5 ° of left and right, in the rotating speed of band sprocket wheel and the linear velocity of pitch wheel than in certain ratio range time, mica tape is overlapping 1/2 left and right on coil, that more rational band state is (referring to Fig. 3, 4), the action principle of above-mentioned rotating tape guide is, the length that mica takes coil case to has increased, for the change at the angle of inclination between mica tape and coil provides condition.
In order to realize the task of not shutting down continuous band; pitch axle 4 is made improvements; to originally only have one to change two into; be former and later two pitch axles; distance between two pitch axles is slightly larger than the thickness of coil case; in the time that coil leans against back pitch and axially moves right, front span axle does not contact with coil case.These two pitch axles are respectively provided with a gear 12,13 and engage (referring to Fig. 6) with the gear 11 on the output shaft of Worm wheel transmission mechanism 5 respectively.The present invention does not do to change to separable belt wheel of the prior art, band sprocket wheel 1 and transmission mechanism 6, back shaft and mounting disc 3 and chain 7.
Operation principle of the present invention is, first manually coil is put on the back shaft of band sprocket wheel, the right-hand member of coil is leaned against on back pitch axle, mica tape in two belt wheels is wound around respectively 2-3 and encloses and fix on coil case through guide wheel after, starter motor, belt wheel carries out band to coil, back pitch axle rotates counterclockwise and is with moving winding to move right simultaneously, now mica tape is outer splayed (referring to Fig. 4), in the time that the left end of coil is gone to back pitch axle place, manually coil case is moved to and is coupling tactile with front span from back pitch axle, coil left direction moves, the angle of mica tape and coil becomes interior splayed (referring to Fig. 3), repeat above-mentioned action, just can complete the number of plies that the mica tape of coil holds, and do not need to shut down, thereby band efficiency promotes greatly.
