As shown in fig. 6, the second inclined surface 27 is provided on the support push block 22', and further referring to fig. 7, when the paper cassette 2 is mounted in the paper cassette frame 1, the driving assembly 6 presses the second inclined surface 27 of the linkage assembly 7 through the first inclined surface 15 to drive the support push block 23, so that the support push block 23 moves downward.
As shown in fig. 1, when the user closes the paper cassette 2 of the printer, the paper cassette 2 is pushed forward toward the paper cassette frame 1, and the first inclined surface 15 of the front end projection 14 contacts the second inclined surface 27 in the linkage assembly 7. The paper box 2 continues to advance, the second inclined surface 27 is extruded by the first inclined surface 15 to generate relative sliding, and the linkage module 22 overcomes the elasticity of the second elastic piece 23 to move downwards. At this time, the pressure applied to the first pressing portion 21 by the second pressing portion 29 disappears, and the paper feed roller module 17 rotates counterclockwise about the rotation axis by the compression force of the first elastic member 18. When the first inclined surface 15 and the second inclined surface 27 slide relatively to the end of the inclined surface, the first flat portion 16 of the front end bump 14 is matched with the second flat portion 28 of the linkage module 22, at this time, the connecting piece 35 is located at the top of the elongated through hole 34, the paper box is mounted in place, and the paper feeding roller 20 is located at the first position nearest to the paper and is pressed against the paper.
When the user opens the paper cassette 2 of the printer, the paper cassette 2 is pulled back toward the paper cassette housing 1, the first flat portion 16 and the second flat portion 29 of the front end projection 14 slide relatively, and the paper cassette 2 is pulled back continuously, and the first inclined surface 15 contacts the second inclined surface 27. At this time, the linkage module 22 moves upward under the second restoring force of the second elastic member 23, and the second pressing portion 29 presses and supports the first pressing portion 21, and applies pressure to the first pressing portion 21. Since the second restoring force of the second elastic member 23 is greater than the first restoring force of the first elastic member 18, the linkage module 22 supports the paper feeding roller module 17 against the first restoring force so that the paper feeding roller module 17 rotates clockwise around the rotation axis, and when the first inclined surface 15 is separated from the second inclined surface 27, the barb portion 31 moves to the top of the slot 32, and at this time, the linkage module 7 does not move any more. The paper feed roller 20 is located at the second position farthest from the paper, and is completely separated from the paper.
In the above embodiments, the first and second flat portions 16, 28 are not necessary, and in some embodiments, mating may be performed using only beveled surfaces.
According to the utility model, a linkage assembly 6 is arranged between the paper box 2 and the paper feeding assembly 8 to serve as a transmission medium, the paper feeding roller module 17 is driven to vertically descend by means of horizontal pushing of the paper box 2, the paper feeding roller module 17 supported by the linkage module 22 is sprung by the first elastic piece 18 above, the rotating shaft rotates anticlockwise to drive the paper feeding roller to descend to the lowest point, and then the printer sends an instruction to control the paper stacking plate 9 to lift, and the paper is driven to ascend so that the upper surface of the paper is compressed by the paper feeding roller 20. When the paper cassette 2 is horizontally pulled out, the links of the transmission chain respectively perform reverse movement to drive the paper feeding roller 20 to lift off the upper surface of the paper.
In some embodiments, the linkage module as an intermediate link may be omitted, thereby further reducing the number of parts. At this time, the driving portion 24 of the support push block 22' is directly disposed on the paper feeding roller module 17, the first elastic member 18 is a tension elastic member, and the initial position of the paper feeding roller 20 is a position away from the paper. As in the previous embodiment, the driving portion 24 is provided with a through hole 26, the shape of the through hole 26 may be square, circular or oval, and a slope structure including a second slope 27 and a second flat portion 28 connected to the second slope 27 is provided under the inner surface of the through hole 26. When the user pushes the paper cassette 2 forward, the first inclined surface 15 of the front end tab 14 of the paper cassette 2 contacts the second inclined surface 27 of the linkage assembly 22. The paper cassette 2 continues to advance, the second inclined surface 27 is pressed by the first inclined surface 15 to generate relative sliding, at this time, the paper feeding roller module 17 rotates anticlockwise against the first restoring force of the first elastic member 18, when the first inclined surface 15 and the second inclined surface 27 finish relative sliding, the first flat portion 16 contacts with the second flat portion 28, the paper feeding roller 20 stops moving, and the paper cassette 2 is installed in place. When the user pulls the paper cassette 2 backward, the paper feed roller 20 is gradually separated from the paper due to the first inclined surface 15 and the second inclined surface 27, the paper feed roller module 17 moves clockwise along the rotation axis by the first restoring force, and the paper feed roller is maintained at the farthest position of the paper separation by the first restoring force after the first inclined surface 15 is separated from the second inclined surface 27.
The embodiment controls the number of parts in each link of the transmission link to the minimum, avoids complex structure and electronic control, and the linkage module and the paper feeding roller module automatically reset by means of own restoring force when appropriate, so that the automation degree of the paper feeding mechanism is improved, and the movement of the paper box and the movement of the paper feeding roller module can be synchronous by using inclined surface contact transmission.
What has been described above is merely some embodiments of the present utility model. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model.
