Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0023] Such as Figures 1-4As shown in the figure, an adaptive anti-collision paper receiving mechanism provided by an embodiment of the present application will be described. The adaptive anti-collision paper receiving mechanism includes a base 7, a paper receiving base 9, a paper receiving board 1, a linear reciprocating drive assembly, and a proximity sensor 13. Among them, the base 7 is arranged inside the lower door 2 of the cabinet, that is, the base 7 is arranged inside the cabinet, and the cabinet is omitted in the figure. A bracket is arranged on the base 7. The bracket is an inverted U-shaped bracket. A typewriter 5 is placed on the upper surface of the bracket. The paper receiving base 9 is installed between the two side plates of the bracket. An outlet 14 and an inlet / outlet 16 are opened on the lower door 2. The outlet 14 is located above the inlet / outlet 16. A roll paper 6 is rotatably arranged on the base 7 through a mounting frame. The paper of the roll paper 6 can be used for the typewriter 5 to print. A displacement sensor 4 is installed on the typewriter 5 through a Z-shaped frame. The displacement sensor 4 is used to sense the movement of the paper.

[0024] Among them, the paper outlet side of the typewriter 5 is aligned with the outlet 14. The paper after printing can be discharged through the outlet 14. The paper receiving base 9 is aligned with the inlet / outlet 16. The paper receiving board 1 is slidably arranged on the paper receiving base 9. The linear reciprocating drive assembly is arranged on the paper receiving base 9 and drives the paper receiving board 1 to reciprocate through the inlet / outlet 16. That is, the paper receiving board 1 can extend out of the lower door 2 through the inlet / outlet 16 to receive the paper discharged through the outlet 14; when not in use, the paper receiving board 1 can be recycled inside the lower door 2 through the inlet / outlet 16 to prevent the staff from colliding with the paper receiving board 1. To further prevent the risk of the paper receiving board 1 being collided by the staff, among them, the proximity sensor 13 is arranged on the front end face of the paper receiving board 1. The end face where the paper receiving board 1 first extends out of the inlet / outlet 16 is the front end face. The proximity sensor 13 can sense whether the staff is approaching the paper receiving board 1. When the staff is about to collide with the paper receiving board 1, the proximity sensor 13 sends the sensed situation to the control center inside the cabinet, and the control center then controls the speaker to issue a voice warning; at the same time, it is fed back to the linear reciprocating drive assembly to control the paper receiving board 1 to retract a certain distance, effectively avoiding the staff from colliding with the paper receiving board 1.

[0025] In this embodiment, the paper receiving base 9 is L-shaped, including a bottom plate and a vertical plate. The end face of the vertical plate fits with the lower door 2, which has a positioning function. L-shaped side plates 19 are provided on both sides of the upper surface of the bottom plate. The L-shaped side plates 19 are welded to the side plates of the bracket or fixed by a number of countersunk screws. A chute is formed between the L-shaped side plates 19 and the bottom plate. The two side edges of the paper receiving board 1 are slidably arranged in the chute. Specifically, two wavy dynamic pressure elastic sheets 10 are arranged in each chute. The paper receiving board 1 slides between the two dynamic pressure elastic sheets 10. Through the arrangement of the dynamic pressure elastic sheets 10, the friction when the paper receiving board 1 slides can be reduced. At the same time, compared with the structure of a guide rail or a row of rollers, the wavy dynamic pressure elastic sheets 10 have the advantages of simple production, low cost, and convenient installation.

[0026] In this embodiment, two parallel sliding grooves 15 are provided on the bottom plate. The linear reciprocating driving assembly is arranged on the lower surface of the paper receiving base 9. The linear reciprocating driving assembly includes a servo motor 8, a lead screw 12, a stud base 11, a guide rod 17 and a slider base 18. The servo motor 8 is fixed on the bottom plate and away from the vertical plate. One end of the lead screw 12 is in transmission connection with the servo motor 8, and the other end is rotatably arranged on the vertical plate through a bearing. The stud base 11 is in transmission connection with the lead screw 12 and passes through one of the sliding grooves 15 to be connected with the paper receiving board 1. The guide rod 17 is arranged in parallel with the lead screw 12. One end of the guide rod 17 is fixed on the vertical plate, and the other end is installed on the bottom plate through a shaft seat. The slider base 18 is slidably arranged on the guide rod 17 and passes through the other sliding groove 15 to be connected with the paper receiving board 1. When the servo motor 8 rotates forward or backward, it drives the lead screw 12 to rotate, thereby driving the stud base 11 to move on the lead screw 12. When the stud base 11 reciprocates, it drives the paper receiving board 1 to reciprocate.

[0027] In this embodiment, a baffle is provided at the front end of the paper receiving board 1. The baffle and the paper receiving board 1 are in an L shape. The proximity sensor 13 is arranged on the outer side surface of the baffle. The baffle can prevent the paper from sliding out of the paper receiving board 1 after falling on the paper receiving board 1.

[0028] In the non-working state, the paper receiving board 1 is located inside the lower door 2, and the baffle is flush with the outer surface of the lower door 2.

[0029] In the working state, the typewriter 5 works to move the paper of the roll paper 6. The displacement sensor 4 senses the movement of the paper and transmits the signal to the servo motor 8. The servo motor 8 drives the lead screw 12 to rotate, and drives the paper receiving board 1 to extend outwards through the inlet and outlet 16 via the stud base 11. After the typewriter 5 finishes printing and cutting, the paper falls on the paper receiving board 1.

[0030] When someone stands in front of the inlet and outlet 16 and is not at a safe distance, the proximity sensor 13 will give a warning, and the horn will remind the person to get out of the way.

[0031] The adaptive anti-collision paper receiving mechanism provided in this embodiment not only ensures the safety of pedestrians, but also ensures the normal use of the equipment, meets the basic dimensions of the equipment and the humanized design. This mechanism has high automation, is easy to use, and has a good use experience and application prospect.

[0032] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
