[0002] A printer is an output device that transfers digital information from electronic devices such as computers to carriers such as paper and film through media such as printhead, toner, and ink, forming a physical copy.

[0003] In existing similar devices, when the stacked paper at the paper output port reaches a certain height, it can easily obstruct the discharge of subsequent paper, resulting in poor paper output. Therefore, a paper output tray for preventing paper jams in laser printers is proposed to address the above problem. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Specific implementation examples are given below.

[0016] Please see Figures 1-4This utility model provides a paper output tray for preventing paper jams in laser printers, including an output tray 1 and a carrier box 101. An installation plate is slidably connected inside the carrier box 101. A carrier component 2 is provided at the bottom corner of the output tray 1. Positioning components 3 are provided on both sides of the output tray 1 and the carrier box 101. The carrier assembly 2 includes two sets of mounting plates 201 fixed to the bottom of the paper output tray 1. A push rod 202 is fixed to the bottom of each mounting plate 201. Two ink distribution cylinders 203 are fixed to the top of the mounting plate. The push rod 202 extends into the interior of the ink distribution cylinders 203, and a push plate 204 is fixed to the bottom of the push rod 202. During operation, when the paper stacked on top of the paper output tray 1 reaches a certain thickness, it can easily block the printer's paper output port, hindering smooth paper output. The mounting plate, which slides inside the carrier box 101, provides installation space for subsequent components. Mounting plates 201 from the carrier assembly 2 are installed at the corners of the bottom of the paper output tray 1. These mounting plates 201 connect the paper output tray 1 and the carrier assembly 2. A push rod 202 is fixedly connected to the bottom of the first mounting plate 201. A corresponding oil separator 203 is installed on the top of the mounting plate corresponding to the position of the push rod 202. The push rod 202 extends into the interior of the oil separator 203 and can move along the axial direction of the oil separator 203. A push plate 204 is fixedly connected to the bottom of the push rod 202. Its outer diameter matches the inner diameter of the oil separator 203, so that the push plate 204 can move smoothly inside the oil separator 203. When the paper on the top of the paper tray 1 reaches a certain weight, the gravity is transmitted to the push plate 204 through the push rod 202, causing the push plate to move downward along the oil separator 203, thereby driving the paper tray 1 to sink synchronously, automatically increasing the gap between the paper outlet and the tray, and ensuring smooth paper output.

[0017] Furthermore, such as Figure 1 and Figure 2 As shown, the positioning component 3 includes a bottom plate 301 and a top plate 302 respectively fixed to both sides of the paper output tray 1 and the carrier box 101. A positioning rod 303 is fixed to the top of the bottom plate 301. The positioning rod 303 passes through the top plate 302 and extends to the top of the top plate 302. During operation, two sets of bottom plates 301 are symmetrically installed on both sides of the carrier box 101, and top plates 302 are installed at the same positions on both sides of the paper output tray 1. The positioning rod 303 at the top of the bottom plate 301 passes through the top plate 302 and extends to the top of the top plate 302. When the paper output tray 1 is lowered by gravity, the top plate 302 can move along the axial direction of the positioning rod 303 to ensure the stability of the paper output tray 1 when it moves and to prevent the paper output tray 1 from deviating during the movement.

[0018] Furthermore, such as Figure 4As shown, a second mounting plate 207 is fixedly connected to the center of the bottom of the mounting plate, and a second push rod 208 is fixedly connected to the bottom of the second mounting plate 207. A main oil cylinder 209 is fixedly connected to the center inside the carrier box 101, and a second push plate 210 is fixedly connected to the bottom of the second push rod 208. During operation, the second mounting plate 207 at the bottom of the mounting plate connects the mounting plate and the second push rod 208. The main oil cylinder 209 inside the carrier box 101 is located at the bottom of the second push rod 208, and the second push rod 208 can move along the main oil cylinder 209. The second pusher plate 210, which is fixed to the bottom of the second pusher rod 208, has a size that matches the inner diameter of the main oil cylinder 209. Driven by the second pusher rod 208, the second pusher plate 210 can move along the main oil cylinder 209. When the downward stroke of the two sets of oil cylinders 203 at the top of the mounting plate reaches the limit, the continuous stacking gravity of the paper will be further transmitted to the second pusher rod 208 at the bottom of the mounting plate, driving the second pusher rod 208 to drive the second pusher plate 210 to continue to move downward along the main oil cylinder 209, realizing the secondary sinking of the paper output tray 1.

[0019] Furthermore, such as Figure 3 and Figure 4 As shown, a first spring 205 is fixedly connected to the bottom of the first push plate 204, and a second spring 211 is fixedly connected to the bottom of the second push plate 210. During operation, the first spring 205, rigidly connected to the bottom of the first push plate 204, is located between the oil distribution cylinder 203 and the first push plate 204. The second spring 211, rigidly connected to the bottom of the second push plate 210, is located between the second push plate 210 and the main oil cylinder 209. When the paper output tray 1 bears the weight of the paper, the first spring 205 and the second spring 211 can make the paper output tray 1 and the mounting plate move down smoothly and slowly. When the paper is removed from the tray and the gravity load disappears, the first spring 205 and the second spring 211 will drive the first push plate 204 and the second push plate 210 to quickly reset, driving the paper output tray 1 and the mounting plate back to the initial position, preparing for the next round of paper output.

[0020] Furthermore, such as Figure 4 As shown, several oil distribution cylinders 203 are provided with oil pipes 206 at their bottoms. The ends of the oil pipes 206 are connected to the main oil cylinder 209. During operation, when the first push rod 202 drives the first push plate 204 to move along the inner wall of the oil distribution cylinder 203, the hydraulic oil inside the oil distribution cylinder 203 will be directionally transported to the inside of the main oil cylinder 209 through the oil pipes 206 under the squeezing action of the first push plate 204, forming a linkage transmission.

[0021] Furthermore, such as Figure 1 As shown, limiting strips 102 are fixed to both sides of the top of the paper output tray 1. During operation, the two sets of limiting strips 102 on the top of the paper output tray 1 form a lateral constraint, which can guide the paper to fall accurately into the receiving area on the top of the paper output tray 1, and can also play a lateral limiting role for stacked paper, effectively preventing the paper from shifting or falling off during output or tray lifting.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
