Description

Thermosensitive paper roll

Technical Field

The utility model relates to a thermal paper roll.

Background

The thermal printer is widely applied to the fields of supermarkets, markets, telecommunications, hospitals and the like, and adopts thermal roll paper as a printing medium to print transaction certificates for customers. The heat-sensitive paper is formed by sequentially laminating base paper, a bottom coating, a heat-sensitive coating and a protective layer, and the continuous heat-sensitive paper is wound on the core cylinder to form heat-sensitive roll paper.

The thermal printer usually has a casing, the core includes printing head, stock form support, rubber roll driving piece and cut paper cutter, etc., the stock form support is fixed but the thermal roll paper is rotated when the thermal printer of the conventional structure prints, therefore have great interval between core cylinder and the support shaft of the stock form support and can rotate smoothly, and it is easy to take off the thermal roll paper from the stock form support to change the paper like this. However, the large gap can lead to unstable paper discharge, easy paper deflection and easy paper jam of the thermal paper, so that the roll paper support of the thermal printer with a new structure must be designed to solve the problems.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a thermosensitive paper roll.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a thermal paper roll, includes core barrel and rolls up the scroll on core barrel which characterized in that: the printing machine comprises a printing machine shell, a core barrel and a paper winding shaft, wherein the core barrel is provided with a paper winding shaft fixedly connected with the core barrel, the paper winding shaft is provided with a first rotating part which is in rotating fit with the printing machine shell, and the end part of the paper winding shaft is provided with a connecting part.

The paper winding shaft is inserted into the inner hole of the core cylinder and is tightly matched with the inner hole of the core cylinder.

The first rotating part is a rotating disc connected with the roll paper shaft.

The rotary disc is provided with a boss, and the roll paper shaft is arranged on the boss.

The connecting part is a connecting hole.

The paper winding shaft is in a frustum shape.

And a clamping strip is arranged in the connecting hole.

The utility model has the advantages that: the utility model discloses a ply is rolled up on the core section of thick bamboo, and core section of thick bamboo and scroll axle fixed connection are as an organic whole, then the scroll axle is connected as an organic whole with the stock form pole again, thereby the stock form pole, scroll axle and ply are integrative pivoted when rotating, and because the scroll axle, the stock form pole is accomplished more accurate rotation easily with the printing casing, therefore the stock form support of this structure goes out the paper steady, the paper is difficult crooked and difficult card paper, and the ply has printed the back and only need take out the stock form pole and the scroll axle, then part the stock form axle with the support, change the core section of thick bamboo and scroll axle together.

Detailed Description

Referring to fig. 1 to 5, the present invention discloses a thermal sensitive paper roll, including a core cylinder (not shown in the figures) and a paper roll 1 wound on the core cylinder, wherein the core cylinder is provided with a paper roll shaft 2 fixedly connected with the core cylinder, specifically, tightly fitted, the paper roll shaft 2 is pressed into an inner hole of the core cylinder and tightly fitted with the inner hole of the core cylinder by a press machine, and the paper roll shaft 2 is in a frustum shape as an optimized structure, so that the paper roll shaft 2 is easily inserted by aligning with the inner hole of the core cylinder; the printing machine is characterized in that a first rotating part which is in rotating fit with the printing machine shell is arranged on the paper winding shaft 2, the first rotating part is a rotating disc 3 connected with the paper winding shaft 2, of course, the first rotating part of the structure can also be of other structures, such as a rotating shaft and the like, a semicircular groove is arranged on the printing machine shell, and the edge of the rotating disc 3 can be clamped into the semicircular groove, so that the rotating disc 3 not only can achieve the rotating purpose, but also the semicircular groove can limit the axial movement of the rotating disc 3, and the taking and the placing are convenient; be equipped with boss 4 on the rolling disc 3, the stock form axle 2 sets up on boss 4, thereby has the slot wall that the clearance has been kept away from the semicircle groove between one side of temperature sensing stock form and rolling disc 3 like this, and boss 4 can block the temperature sensing stock form moreover and prevent that the note is crooked when going out paper.

And 2 tip of roll paper axle are equipped with connecting portion, connecting portion are connecting hole 5, 6 tip of stock form pole are equipped with connecting hole 5 complex connecting axle 7, because the temperature sensing stock form needs to be changed, therefore above-mentioned structure is convenient for change, only need take out the stock form support wholly, then part roll paper axle 2 and stock form pole 6, change again, in this structure, temperature sensing stock form and roll paper axle 2 are that the fastening is as a whole part and sell, therefore change also together, because the user pulls down the core section of thick bamboo alone from roll paper axle 2 or make core section of thick bamboo and roll paper axle 2 tight fit be more difficult, convenience of customers changes like this. The connecting hole 5 is internally provided with a clamping strip 8, the connecting shaft 7 is provided with a clamping groove matched with the clamping strip 8, so that the connecting hole 5 and the connecting shaft 7 can enable the roll paper rod 6 and the roll paper shaft 2 to rotate together without tight fit, and the assembling and the separation are easy.

The above detailed description is made on the thermal sensitive paper roll 1 provided by the embodiment of the present invention, and the principle and the implementation of the present invention are explained by applying a specific example, and the description of the above embodiment is only used to help understanding the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
