in order to make the problems to be solved by the present invention more clear, the following description will be made with reference to the accompanying drawings. This example is an example of an embodiment of the present invention, and is not intended as a limitation on the scope of the present invention. Other examples obtained by others without inventive step are within the scope of the present invention.

In the description of the present invention, the term "connected" is broadly interpreted as "fixed", "tied", "suspended" and "nested", the term "force" is broadly interpreted as "elastic force", "magnetic force", "gravity", "frictional force" and "pressing force", the terms "above" or "below" and the like are broadly interpreted as "moving direction", "visual direction" and "gravity direction", the terms "behind" or "before" and the like are broadly interpreted as "moving timing", "execution timing" and "trigger timing", and the terms "wheel" is broadly interpreted as "ball", "gear", "cylinder" and "arc".

The invention provides a container capable of accommodating roll paper and mechanical parts.

Specifically, in this example, as shown in fig. 1 and 2, the roll paper container case 1, hereinafter referred to as a paper cassette in this example, is opened, the upper platen roller and the lower platen roller 2 are respectively disposed on the paper cassette cover and the paper cassette body, when the paper cassette is opened, it is convenient to drop the roll paper into the cassette, replace the roll paper, pull out the paper head to expose the paper cassette, and close the cover.

In particular, in the present embodiment, an arc bottom plate is arranged at the bottom inside the box, so that the roll paper can be rotated to release the paper conveniently, and meanwhile, the mechanical part is isolated and protected.

In the invention, paper drawing power is adopted, certain extrusion force is required between the paper pressing rollers 2, and enough friction force is ensured to drive the paper pressing rollers 2 to rotate.

Specifically, in this example, the two platen rollers 2 have rubber surfaces. When the paper is pulled in place, the platen 2 needs to jam the paper to ensure that it can be pulled off the paper dashed line.

Specifically, in this example, the two platen rollers 2 have tooth-like grooves to increase the sheet resistance.

In the invention, the power for drawing the paper is transmitted to the length metering component and the braking component through the power transmission component.

Specifically, in this example, the platen 2, the metering capstan 5 and the ratchet 3 of the brake assembly are coaxial.

Specifically, in this example, as shown in fig. 3, 4, and 5, the three members rotate coaxially to transmit power.

In the invention, the length metering component sets the length of the paper by adjusting the sliding rail 8.

Specifically, in this example, the adjustment slide rail 8 prevents rotation of the adjustment restriction lever 10.

Specifically, in this example, the adjustment limiting rod 10 is fixed to the metering driven wheel 6, the rotation angle of the metering driven wheel 6 is limited, the number of rotation turns of the metering driving wheel 5 is limited, and the paper length metering is realized.

In the present invention, the reset force is always applied to the driven wheel 6.

Specifically, in this example, the metering spring 13 is fixed to the deflectable shaft 7, and the metering spring 13 provides the force to reset the metering follower.

In the present invention, the length gauge assembly triggers the brake assembly by means of a brake trigger 9.

In particular, in this case, the braking trigger 9 is fixed to the driven metering wheel 6, the braking trigger 9 rotating and pushing the pawl 4 against the ratchet wheel 3, since the displaceable shaft 7 on which the pawl 4 is located can be displaced downwards, without braking taking place.

Specifically, in this example, to make the offset shaft 7 move downward so as to make the metering driven wheel 6 separate from the metering driving wheel, the length from the axis of the pawl 4 to the edge of the pawl 4 and the radius of the ratchet wheel 3 are greater than the sum of the radii of the metering driving wheel 5 and the metering driven wheel 6, the ratchet wheel 3 and the pawl 4 are engaged and then continue to rotate, and the offset shaft 7 is jacked up to offset downward.

In particular, in this example, the adjustment slide 8, the metering follower 6 and the pawl 4 are all on an offset shaft 7, which are independently rotatable and not fixed to the shaft.

In the present invention, a force tending to the driving metering wheel 5 is always applied to the driven metering wheel 6.

Specifically, in this example, the deflectable shaft 7 is coaxial with the driven metering wheel 6, and the biasing spring 14 has an upward rotational force, providing a coupling force between the driving metering wheel 5 and the driven metering wheel.

In the present invention, the power transmission assembly is braked after the deviation of the deflectable shaft 7 is limited.

Specifically, in this example, the downward offset distance of the shiftable shaft 7 is limited by the offset limiting rod 11, and when the shiftable shaft 7 is pushed downward by the pawl 4, the offset limiting rod 11 stops, and the ratchet wheel is jammed, so that the braking is realized.

Specifically, in this example, the shift restricting lever 11 is fixed to the paper cassette.

In the invention, the force of disengaging the ratchet wheel 3 is always applied to the pawl 4 to provide the pawl reset.

Specifically, in this example, the pawl spring 12 applies a disengaging force on the pawl 4, the pawl spring 12 is coaxial with the pawl 4, when the paper is pulled off, the pressure between the ratchet 3 and the pawl 4 disappears, the pawl spring 12 pries the pawl 4, and the brake is released and the next cycle is continued.

Specifically, in this example, the pawl 4 rotates on the offset shaft 7, but has a spline to limit its rotational angle.

The above examples are illustrative of the technical principles of the present invention, and the description is only for explaining the technical principles of the present invention and not for limiting the scope of protection of the claims, so that other example forms based on the above principles are within the scope of protection of the claims.
