Detailed Description
The technical solution of the present invention is further explained by the accompanying drawings and the specific embodiments.
Referring to fig. 1 to 5, a printing paper feeding cassette includes a paper cassette lower cover 1, a paper cassette middle cover 2; one end of the paper box lower cover 1 and one end of the paper box middle cover 2 are pivoted in a rotating mode so that the paper box lower cover and the paper box middle cover can be closed or opened; when the paper box middle cover 2 rotates to the opening position relative to the paper box lower cover 1, the opening on the upper surface of the paper box lower cover 1 is completely exposed, so that a user can conveniently load printing paper into the paper box lower cover 1.
In order that a user can load printing paper into the paper cassette lower cover 1 more easily, the entire width of the paper cassette lower cover 1 is greater than the width of the printing paper, so that the user can load the printing paper without strictly aligning the printing paper with both sides of the paper cassette lower cover 1 when loading the printing paper.
However, since the printing paper does not need to be aligned strictly in the process of being placed in the paper cassette lower cover 1, the printing paper in the paper cassette lower cover 1 may be in an uneven state, which may easily cause paper jam and make the paper not contact the paper feeding rubber roller smoothly in the subsequent printing process, and therefore, the printing paper in the paper cassette lower cover 1 needs to be aligned.
In order to achieve the above alignment operation, an inner side wall of the paper box lower cover 1 is provided with an elastic rib 11 integrally formed with the paper box lower cover 1, and one end of the elastic rib 11 is a free end; the middle cover 2 of the paper box is provided with a pressing block 21 which is matched with the elastic ribs 11 for extrusion;
when the cover 2 in the paper box is in an open state, the distance between the elastic ribs 11 and the other side wall of the paper box lower cover 1 is larger than the width of printing paper, so that the printing paper can be placed into the paper box lower cover 1 without strict alignment and is easier to place; when the cover 2 is in a closed state in the paper box, the pressing block 21 presses the elastic ribs 11 to enable the free end of the elastic ribs to swing towards the direction close to the other inner side wall, so that in the process of closing the cover 2 in the paper box, the elastic ribs 11 can push printing paper to move towards the direction close to the other side wall of the lower cover 1 of the paper box in the swinging process, and the aim of pushing uneven printing paper is fulfilled. Because this embodiment elastic rib 11 and carton lower cover 1 are integrative, can reduce a part for the structure is more stable, has both saved the cost, has increased structural stability again.
The structure can push the printing paper to one side, but the printing paper can be moved to one side excessively, namely, the printing paper is shifted excessively, so that the paper can be extruded and deformed to bend due to insufficient weight and excessive elasticity, and the adverse effect on the printing paper feeding can be caused.
Therefore, in order to prevent the printing paper from excessively deviating, three limiting blocks 12 are arranged on the other inner side wall of the paper box lower cover 1 on the surface facing the elastic ribs 11, and a certain distance is reserved between the limiting blocks 12 and the limiting blocks 12. After the free end of the elastic rib 11 swings towards the direction close to the other side wall, the distance between the free end of the elastic rib 11 and the limiting block 12 is equal to the width of printing paper. Therefore, when the printing paper swings to abut against the stopper 12, the printing paper cannot swing continuously, and thus the printing paper is finally aligned in the region between the elastic rib 11 and the stopper 12 and is strictly aligned.
The number of the limiting blocks 12 can be more or less than three, which belongs to simple replacement of the embodiment and is not described again.
In this embodiment, the specific structures of the elastic ribs 11 and the pressing block 21 are as follows: the lower cover 1 of the carton is further provided with an outer side wall 13 outside the elastic ribs 11, and a certain distance is formed between the outer side wall 13 and the elastic ribs 11 to form a side wall accommodating space 14 of the middle cover 2 of the carton.
The pressing block 21 is arranged on the inner surface of the side wall of the paper box middle cover 2; the sum of the thicknesses of the pressing block 21 and the inner surface of the side wall of the middle cover 2 of the paper box is larger than the thickness of the side wall accommodating space 14.
After the paper box middle cover 2 and the paper box lower cover 1 are closed, the side wall of the paper box middle cover 2 is inserted into the side wall accommodating space 14, and as the sum of the thicknesses of the pressing block 21 and the inner surface of the side wall of the paper box middle cover 2 is larger than the thickness of the side wall accommodating space 14, the pressing block 21 can be extruded with the elastic ribs 11 in the inserting process, and further the automatic ends of the elastic ribs 11 are driven to swing.
In this embodiment, the following structure is further provided: an elastic arm 15 is arranged on the inner surface of the bottom of the paper box lower cover 1, and one side of the elastic arm 15 facing the printer body is a free end; when the free end is lifted, the printing paper in the paper box lower cover 1 is lifted along with the free end and pressed to the paper feeding rubber roller. The printer has a slot for mounting the lower cover 1 of the paper cassette, and a structure for lifting the free end of the elastic arm 15 is arranged in the slot, which belongs to the prior art, so that excessive unfolding is not performed in the embodiment.
In order to enable the free end of the elastic arm 15 to be lifted up by the structure in the slot of the printer, one side of the paper box lower cover 1 facing the printer body is provided with a yielding opening 16 for exposing the free end of the elastic arm 15.
Since the paper box lower cover 1 is provided with the offset opening 16, when the printing paper supply box is taken down, the printing paper can be directly communicated with the outside through the opening, and external substances such as dust and the like can easily fall on the printing paper to cause failure, therefore, in order that when the printing paper supply box is taken down, the offset opening 16 can be closed, the paper box lower cover further comprises a paper box upper cover 3, one end of the paper box upper cover is rotatably pivoted with the side wall of the paper box middle cover 2, so that the paper box upper cover 3 can be opened or closed; when the upper paper box cover 3 is closed, the upper paper box cover 3, the middle paper box cover 2 and the lower paper box cover 1 together enclose a closed paper bin; when the paper box upper cover 3 is opened, one side of the paper box lower cover 1 facing the printer body is exposed outside.
The utility model also provides a printer, include: a printer body and a printing paper supply cassette as described above. This printer in this embodiment is a sublimation photo printer.
The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
