Abstract
The utility model provides a kind of journal printer delivery device transmission mechanism, comprise the collecting cylinder be connected to turnably on support, for reel that journal printer is spued around thereon, the worm screw also comprising a motor and be fixed on motor driving shaft, and the worm gear to be meshed with this worm screw, the side of this worm gear also arranges the first gear of a synchronous rotary, and the side of this collecting cylinder is fixedly connected with the second gear of a synchronous rotary, and this first gear is meshed with the second gear.The journal printer delivery device transmission mechanism that the utility model provides is by adopting worm-drive, and gearratio is comparatively large, and can form self-locking, avoids the restoring force of paper tape to act on after on collecting cylinder and makes driving-chain generation revolution cause paper tape to relax.And worm-drive is relatively more steady, noise is little.
Description
Technical field
The utility model relates to a kind of journal printer delivery device transmission mechanism, especially relates to the worm geared journal printer delivery device transmission mechanism of a kind of employing.
Background technology
Generally be provided with journal printer in financial machine and tool and supportingly have delivery device, the delivery device of prior art is generally driven by motor and gear transmission chain.When journal printer stops paper delivery, delivery device can form certain traction force to paper tape, and paper tape forms reaction force to collecting cylinder, and gear transmission chain may turn round, and causes paper tape to relax.
Utility model content
The technical problem that the utility model solves is, provides a kind of collecting cylinder that can prevent to turn round lax journal printer delivery device transmission mechanism.
The technical scheme that the utility model solves the problems of the technologies described above is, a kind of journal printer delivery device transmission mechanism is provided, comprise the collecting cylinder be connected to turnably on support, for reel that journal printer is spued around thereon, the worm screw also comprising a motor and be fixed on motor driving shaft, and the worm gear to be meshed with this worm screw, the side of this worm gear also arranges the first gear of a synchronous rotary, the side of this collecting cylinder is fixedly connected with the second gear of a synchronous rotary, and this first gear is meshed with the second gear.
Preferably, this first gear and the second gear are the spur gear of pairing.
Preferably, this first gear and the second gear are the helical gear of pairing.
Preferably, number of threads is 1.
Preferably, worm screw, worm gear, the first gear and the second gear all adopt plastic cement material.
The journal printer delivery device transmission mechanism that the utility model provides is by adopting worm-drive, and gearratio is comparatively large, and can form self-locking, avoids the restoring force of paper tape to act on after on collecting cylinder and makes driving-chain generation revolution cause paper tape to relax.And worm-drive is relatively more steady, noise is little.
Accompanying drawing explanation
The perspective view of a kind of journal printer delivery device transmission mechanism that Fig. 1 provides for the utility model one embodiment;
Fig. 2 is the structure for amplifying schematic diagram of the running part of the delivery device of journal printer shown in Fig. 1 transmission mechanism.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail below by detailed description of the invention.
Refer to Fig. 1 and Fig. 2, the utility model one embodiment provides a kind of journal printer delivery device transmission mechanism, comprises collecting cylinder 1, second gear 2, built-up gear 3, worm screw 4, motor 5 and support 6.Wherein motor 5 is fixed on support 6, and built-up gear 3 is fixed on support 6 turnably, and this collecting cylinder 1 is connected on support 6 by rotating shaft (non-label) turnably, for the reel that journal printer (not shown) spued around thereon.This collecting cylinder 1 is fixedly connected with the second gear 2 of a synchronous rotary near the side of support 6.This worm screw 4 is fixed on the driving shaft (non-label) of motor 5, and this built-up gear 3 comprises coaxial being connected, and the worm gear 31 of synchronous rotary and the first gear 32, wherein worm gear 31 is meshed with worm screw 4, and the first gear 32 is meshed with the second gear 2.After being energized by motor 5, rotary actuation worm screw 4, built-up gear 3 and the second gear 2 rotate successively, and collection operation is carried out in the rotation of final drive collecting cylinder 1.
This second gear 2, built-up gear 3 and worm screw 4 all adopt plastic cement material.The head number of this worm screw 4 is 1, in other alternate embodiments, also can adopt a number be 2 worm screw.The number of teeth of this first gear 32 and diameter are all less than the number of teeth and the diameter of the second gear 2.This first gear 32 and the second gear 2 are the helical gear matched, and also all can adopt the spur gear of pairing in other alternate embodiment.
The journal printer delivery device transmission mechanism that the utility model provides is by adopting worm-drive, and gearratio is comparatively large, and can form self-locking, avoids the restoring force of paper tape to act on after on collecting cylinder 1 and makes driving-chain generation revolution cause paper tape to relax.And worm screw 4 gearratio is comparatively steady, noise is little.
Above content is in conjunction with concrete embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made.
