100 and driven voller 200, the driven voller 200 and 100 Elastic Contact of drive roll, the driven voller 200 act on drive roll 100
On pressure be less than the bar code printer (not shown) act on the pressure on medium；The linear speed that the drive roll 100 rotates
Degree prints chart speed degree greater than the bar code printer.
The cutting means include left plate 300 and right side plate 400, and the drive roll 100 and driven voller 200 are rotatablely installed
Between the left plate 300 and right side plate 400, the cutting means include motor 500, and the motor 500 passes through gear set
Part 510 and the drive roll 100 are sequentially connected, and the gear assembly 510 is installed on the left plate 300.
The driven voller 200 is installed on closure bracket 600, and one end of the closure bracket 600 is rotationally connected with described
On right side plate 400, the other end is removably connected on the left plate 300 by clamping close device 700.
Left fixed block 630 and right fixed block 640 are installed, the driven voller 200 is rotatablely installed on the closure bracket 600
Between the left fixed block 630 and right fixed block 640.
It is connected between the closure bracket 600 and the right side plate 400 by shaft 650, the closure bracket 600 is with institute
Shaft 650 is stated as axle center overturning.
The clamping close device 700 includes being fixedly installed in the 300 upper switch guide pad 730 of left plate, and the switch is led
It is equipped with switch into block 730 and leads 710 bars, reset spring 720, the closure bracket 600 are arranged on the switch guide 710
The other end be equipped with holding section 620, the switch guide 710 left and right Elastic Sliding in the switching guide block 730, with and institute
The holding section 620 for stating closure bracket 600 is separated or engages.
The roll surface of the drive roll 100 is shiny surface, and the roll surface of the driven voller 200 is made of flexible plastic cement.
It is by the purpose that the roll surface of drive roll 100 is set as shiny surface: is conducive to medium actively: at the uniform velocity skidding on 100, by driven voller
The purpose that 200 roll surface is set as Elastic plastic-rubber is to step up medium uniformly in axial direction, to make medium according to stable side
It to export, and then tenses medium uniformly while transmission, removes colour band at the uniform velocity and backrush.
The length of the driven voller 200 is less than the length of the drive roll 100, and the driven voller 200 is located at the active
100 top of roller and the side for leaning on shaft 650.It further include shell (not shown), the cutting means and media transportation mechanism installation
In in the shell, being also equipped with Destaticizing device (not shown) in the shell, the Destaticizing device can emit electrification
Ion can be neutralized effectively and avoid electrostatic because of electrostatic caused by friction to medium transmission and the influence of cutting precision.
The working principle of the invention and process are as follows: media transportation mechanism of the invention is installed on the exit slot of bar code printer
Between the paper feed port 800 of cutting means, cutting means include motor 500, left plate 300, right side plate 400 and cutter assembly
810, the both ends of active rod 100 pass through bearing 110 respectively and are fixed on left plate 300 and right side plate 400, the gear assembly
510 include the third that the second gear connected with the first gear of motor driven axis connection with cutter assembly is connected with drive roll
Gear, the successively ratcheting connection of first gear, second gear and third gear can pass through first gear when motor 500 is run
Second gear and the rotation of third gear are driven, the diameter of first gear, second gear and third gear is different, therefore, motor 500
Cutter assembly 810 and drive roll can be driven to rotate at different rates, to make drive roll 100 and driven voller 200 by medium
The advantages of stable is sent to cutting means, and drive roll 100 is driven using three gear drives, is arranged in this way is: not only saving
Cost moreover, the cutter assembly 810 of cutting means and drive roll 100 is made to keep stable rotating ratio makes bar code printer
The revolving speed three of paper delivery speed, the linear velocity of drive roll 100 and cutter assembly 810 matches, and can make to print and cut more
Add smooth, improves the cutting precision and speed of cutting means, and be conducive to reduce dielectric loss, improve printing and cut effect
While rate, printing cost can be effectively reduced.
In the present embodiment, the drive roll 100 and 200 Elastic Contact of driven voller, the purpose of Elastic Contact is can be to master
Medium between dynamic roller 100 and driven voller 200 uniformly steps up axially, it is therefore prevented that since medium causes in axially loaded unevenness
Not accurate to position, the pressure between drive roll 100 and driven voller 200 is less than the bar code printer and acts on the pressure on medium
Power, the purpose being arranged in this way is: when drive roll 100 and driven voller 200 export medium, due to rubbing between printer and medium
The coefficient of friction wiped between coefficient and drive roll and driven voller and medium is close, therefore, when printer acts on the pressure on medium
When power acts on the intensifying force on medium greater than drive roll 100 and driven voller 200, reverse friction power of the medium in printer is big
In positive frictional force of the medium between drive roll 100 and driven voller 200；Simultaneously as the linear velocity that drive roll 100 rotates is big
Chart speed degree is printed in the bar code printer, therefore, when drive roll 100 and driven voller 200 drive medium motion, drive roll
100 can skid on medium, and the beneficial effect being arranged in this way is: drive roll 100 conveys medium guiding with driven voller 200 same
When medium can be tensed, and can be avoided medium and pulled out bar code printer by force, printing is caused to malfunction.When medium is led
When dynamic roller 100 and driven voller 200 tense, medium can overcome the viscous force of colour band, at the uniform velocity remove with colour band, colour band is by backrush
When, medium will not enable media to stable be sent to cutting means with colored band backrush.
It is above-mentioned to elaborate realization principle of the invention, specifically, connection relationship of the invention and structure are as follows: drive roll
100 both ends are rotationally connected on left plate 300 and right side plate 400 by bearing 110, and the both ends of driven voller 200 pass through bearing
210 are connected on left fixed block 630 and right fixed block 640, and left fixed block 630 and right fixed block 640 are installed on closure bracket 600
On, one end of closure bracket 600 is rotationally connected on right side plate 400 by shaft 650, and switching guide block 730 is fixedly installed in
On left plate 300, switch guide 710 is arranged in the switching guide block 730, and reset spring 720 can make switch guide 710
The left and right Elastic Sliding in switching guide block 730.Closure bracket 600 can be conveniently set to be opened and closed, closure bracket 600 being capable of edge
The shaft 650 is overturn, and driven voller 200 can be made to contact or leave drive roll 100, in use, closing the disengaging of switch guide 710
Bracket 600 is closed, closure bracket 600 is flipped to one side, medium is placed between drive roll 100 and driven voller 200, then will be closed
It closes bracket 600 to be clamped on switch guide 710, at this point, homogeneous media is just pressed on drive roll 100 by driven voller 200, in this way
Structure convenient for operation and installation, be conducive to repair and maintenance.
The above embodiment is a preferred embodiment of the present invention, but embodiments of the present invention are not by above-described embodiment
Limitation, other any changes, modifications, substitutions, combinations, simplifications made without departing from the spirit and principles of the present invention,
It should be equivalent substitute mode, be included within the scope of the present invention.
