Description
Technical field
The present invention relates to a kind of backrush axle and its printer with automatic loose configuration.
Background technique
In recent years, thermal transfer printer is usually using the used carbon ribbon of backrush axle backrush, as printing carries out, backrush axle
Therefore upper winding increasingly tightlier, when replacing carbon ribbon, will exist with carbon ribbon volume and be difficult to remove from backrush axle with carbon ribbon
The problem of.In addition, printer is twined in print label, usually using the lining paper of backrush axle backrush label paper as printing carries out
The lining paper being wound in backrush axle also the more will twine the more tight, when replacing label paper, equally exist what lining paper was difficult to remove from backrush axle
Problem.
There are two types of forms for the common rolling consumptive material backrush axle of tradition, and one is a recycling paper axis, volume are covered in backrush axle
It is complete to be taken out with recycling paper axis.Second is directly to roll up backrush consumptive material in backrush axle, will by certain operation after having rolled up
Axis unclamps, and takes out backrush consumptive material.The first above form is abandoned since most backrush consumptive material all needs to abandon
Recycling paper axis can not be taken out when consumptive material, not environmentally.It needs to do certain operational motion and backrush axle could be unclamped for second, and
Both hands simultaneously operation is generally required, the complexity of disassembly is increased, increases the training cost of operator.
Summary of the invention
The purpose of the present invention is to overcome the shortcomings of the existing technology, and providing one kind can unclamp automatically, dismount consumptive material just
Prompt backrush axle.
In order to solve the above technical problems, present invention employs following technical measures:
A kind of backrush axle with automatic loose configuration is used for backrush printing consumables, including backboard, baffle, rotary shaft, master
Bracket, the main support are set in the rotary shaft, and the printing consumables is wrapped on the main support, and the rotary shaft can
To drive the main support synchronous rotary, the backboard and the baffle are separately fixed at the both ends of the rotary shaft, the master
Bracket is between the baffle and the backboard, and the main support can be between the baffle and the backboard along the rotation
