Description

Technical Field

[0001] The utility model belongs to the technical field of printers, and in particular relates to a stable printer conveying mechanism. Background Art

[0002] A printer is one of the output devices of a computer, which is used to print the computer processing results on related media. When the printer is in use, you need to place a stack of printing paper in the designated position first. After starting the printer, the conveying mechanism on it can feed the printing paper into the printing position one by one, so as to carry out printing.

[0003] The conveying mechanism on the existing printer is prone to two problems when feeding paper. One is that the upper and lower papers are easy to stick together, resulting in multiple sheets of printing paper being fed at one time. The other is that the stacked paper piles are easy to become scattered, affecting the subsequent paper feeding process. Therefore, it is necessary to design a new printer conveying mechanism to solve this problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] See also Figures 1 to 5, is an embodiment of the utility model, and this embodiment provides a technical solution: a stable printer conveying mechanism, including a body 100, a receiving chamber 200 is provided inside the body 100, a paper slot 300 is placed inside the receiving chamber 200, and the paper slot 300 containing printing paper 700 can be put into the interior of the receiving chamber 200, and a placement seat 400 is provided inside the paper slot 300 to hold the printing paper 700, and a spring 500 is fixedly connected between the bottom surface of the placement seat 400 and the inside of the paper slot 300 to elastically support the placement seat 400, and the placement seat 400 includes a base 401, an inclined step 402, and a limit The side panels 403, the limiting rear panel 404 and the track 405, the inclined step 402 is fixed to the front end of the base 401, and one side of the inclined step 402 is an inclined surface. After the printing paper 700 is placed on the placement seat 400, its front end is supported by the inclined step 402. At this time, the front end of the printing paper 700 is separated to a certain extent, reducing the probability of adhesion. The limiting side panels 403 are provided with two and are located on both sides of the top surface of the base 401. The limiting side panels 403 and the limiting rear panel 404 are slidably connected to the top surface of the base 401 through the track 405. The printing paper 700 is placed on the top surface of the placement seat 400. By adjusting the limiting side panels 403 and the limiting rear panel 404 04 slides, so that it can surround the outside of the printing paper 700, and play a role in limiting the printing paper 700. The interior of the accommodating chamber 200 is located at the front end top of the printing paper 700 and is rotatably connected with a paper feeding assembly 600. The paper feeding assembly 600 includes a round roller 601, a rubber abutment edge 602, a side plate 603 and a central axis 604. The central axis 604 is rotatably connected to the interior of the accommodating chamber 200 through a rotating motor. Two side plates 603 are provided and symmetrically fixed on the central axis 604. The round roller 601 is fixedly connected between the two side plates 603. The rubber abutment edge 602 is symmetrically connected to the upper and lower surfaces of the round roller 601. When feeding paper, the paper feeding assembly 600 is started. The motor is driven to rotate, thereby driving the round roller 601 to rotate, and the rubber contact edge 602 will squeeze and push the top printing paper 700 to send it out. The spring 500 always has a tendency to push the placement seat 400 together with the printing paper 700 upward, thereby ensuring that the printing paper 700 can resist the rotating rubber contact edge 602. For the printing paper 700 below the top layer, firstly, the inclined step 402 separates the front end of the printing paper 700 to a certain extent, and secondly, the printing paper 700 below is affected by gravity and is more easily separated from the top printing paper 700. Therefore, it is not easy to have the problem of conveying multiple sheets of printing paper 700 at one time.

[0023] In this embodiment, preferably, sliding piles are fixed to the bottom of the limiting side plates 403 and the limiting rear plates 404, and the sliding piles are slidably connected to the tracks 405 opened on the top surface of the base 401, thereby realizing the sliding connection between the limiting side plates 403 and the limiting rear plates 404 and the base 401.

[0024] In this embodiment, preferably, a lifting assembly 800 is arranged between the front and rear ends of the placement seat 400 and the inside of the paper slot 300. The lifting assembly 800 includes a fixed lifting rod 801 and a fixed ring 802. The fixed lifting rod 801 is fixed inside the paper slot 300 and is slidably connected with the fixed ring 802 fixed at the front and rear ends of the placement seat 400 to improve the stability of the base 401 during the lifting and moving process.

[0025] In this embodiment, preferably, the lifting assembly 800 further includes an anti-falling head 803 , which is fixed to the top of the fixed lifting rod 801 and forms a T-shaped structure to prevent the base 401 from falling off.

[0026] In this embodiment, preferably, an auxiliary paging component 900 is provided at the top front end of the paper slot 300. The auxiliary paging component 900 can further paginate the printing paper 700. The auxiliary paging component 900 includes a fixed pile 901, a rubber head 902 and an anti-slip pattern 903. The fixed pile 901 is fixed on the paper slot 300 and extends to the top front end of the printing paper 700. The rubber head 902 is fixed on the top of the fixed pile 901. The anti-slip pattern 903 is provided on the side surface of the rubber head 902 facing the printing paper 700. During the paper feeding process, the top layer of the printing paper 700 is pushed out by the rubber contact edge 602, while the lower printing paper 700 is blocked by the rubber head 902 and the anti-slip pattern 903 to complete the paging.
