DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1. The purpose of this embodiment is to facilitate the solution of the problem that when using the paper in the paper placement cassette of a large logarithm printer in the later stage, the paper at the bottom may be at a relatively low position, which may cause difficulties or impossibilities for the printer to grab the paper, resulting in printing errors or stops, thereby reducing work efficiency. Please refer to Figures 1 - 4, A printer paper placement box, comprising a printer body 100 and a placement box body 200. A placement slot 110 corresponding to the placement box body 200 is provided in the printer body 100. The placement box body 200 is movably inserted into the printer body 100. A partition 210 is installed in the placement box body 200. An activity slot 211 is provided in the partition 210. A top plate 240 is arranged in the activity slot 211. A cavity 230 is provided in the placement box body. A control component 300 for controlling the top plate 240 is arranged in the cavity 230.

[0023] The control component 300 includes a fixed block 310 installed at the bottom of the top plate 240. A driving rod 320 is rotatably inserted into the fixed block 310. A fixed rod 330 is installed in the cavity 230. A driving sleeve 340 is sleeved on the fixed rod 330. A groove 311 is provided in the fixed block 310. A rotating rod 312 is fixedly installed in the groove 311. Rotating slots 321 are provided at both ends of the driving rod 320. The two ends of the rotating rod are inserted between the fixed rod 330 and the driving sleeve 340 through the rotating slots 321. A first spring 331 is sleeved outside the fixed rod 330. The first spring 331 is located at the side of the driving sleeve 340. One end of the first spring 331 abuts against the inner wall of the cavity 230, and the other end of the first spring 331 abuts against the side wall of the driving sleeve 340.

[0024] A telescopic rod 231 is fixedly installed at the bottom of the top plate 240. A second spring 232 is sleeved outside the telescopic rod 231. The second spring 232 and the telescopic rod 231 are arranged in two groups. The two groups of second springs 232 and the telescopic rod 231 are symmetrically arranged on both sides of the control component 300. A slider 341 is installed at the bottom of the driving sleeve 340. A sliding groove 350 corresponding to the slider 341 is provided in the cavity 230. The sliding groove 350 communicates with the cavity 230. The slider 341 is slidably arranged in the sliding groove 350. The control component 300 is arranged in two groups. The two groups of control components 300 are symmetrically arranged in the cavity 230 with the fixed block 310 as the center.

[0025] The driving rod 320 is arranged in the fixed block 310 in the control component 300. The driving rod 320 is connected to the fixed rod 330 and the driving sleeve 340 through the rotating slots 321. A slider 341 is installed at the bottom of the driving sleeve 340. The slider 341 corresponds to the sliding groove 350 in the cavity 230. When the height of the paper stack changes, the slider 341 on the driving sleeve 340 will slide in the sliding groove 350. In this way, through the movement of the slider 341, the height of the top plate 240 can be automatically adjusted to ensure that the top paper always maintains the best state of contact with the contact surface of the printer transmission system.

[0026] The first spring 331 in the control component 300 is installed on the side of the driving sleeve 340. One end contacts the inner wall of the cavity 230, and the other end contacts the side wall of the driving sleeve 340. The function of the spring is to provide the stability and elastic adjustment ability of the top plate 240. When the height of the paper stack decreases, the spring can automatically adjust its length, so that the supporting force of the top plate 240 on the paper stack remains appropriate, and at the same time ensure that the paper will not cause problems such as poor transmission or paper jams due to uneven pressure of the top plate 240.

[0027] A telescopic rod 231 is fixed to the bottom of the top plate 240, and a second spring 232 is sleeved outside the telescopic rod 231. These spring systems are symmetrically arranged on both sides of the control component 300 to ensure that the top plate 240 can move smoothly when the height of the paper stack changes, and avoid situations such as printer grasping failure or printing quality decline caused by different paper heights.

[0028] The slider 341 installed at the bottom of the driving sleeve 340 is connected to the cavity 230 through the chute 350. The sliding design of the slider 341 not only enables the top plate 240 to move smoothly when the paper height changes, but also ensures that no additional friction or resistance is generated during the adjustment process of the top plate 240, thereby improving the reliability and durability of the entire control system.

[0029] In this embodiment: The driving rod 320 in the fixing block 310 is connected to the fixing rod 330 and the driving sleeve 340 through the rotating groove 321. The slider 341 is installed at the bottom of the driving sleeve 340, corresponding to the chute 350 in the cavity 230. When the height of the paper stack changes, the slider 341 on the driving sleeve 340 moves in the chute 350 in the cavity 230, so that the top plate 240 can automatically adjust its height, ensuring that the top paper always maintains good contact with the printer transmission system, thereby avoiding problems such as difficult grasping or printing errors.

[0030] Embodiment 2. This embodiment aims to facilitate the solution of the problem that the plate may be offset or unstable during the adjustment process. This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1 - 4 .

[0031] A limiting plate 250 is installed inside the placement box body. An auxiliary groove 251 is formed inside the limiting plate 250. Limiting rods 241 are installed on both sides of the top plate 240. The limiting rods 241 are inserted into the auxiliary groove 251. An auxiliary material is movably sleeved outside the limiting rods 241. An auxiliary rack 252 corresponding to the auxiliary gear 242 is arranged inside the auxiliary groove 251. The auxiliary gear 242 meshes with the auxiliary rack 252. The cooperation of the auxiliary gear 242 and the auxiliary rack 252 provides additional support and stability, ensuring that the top plate 240 can move smoothly when adjusting the height, thus effectively avoiding problems such as uneven stacking or increased transmission resistance that may occur when the paper stack is at a lower bottom height.

[0032] In this embodiment: Through the design of the limiting plate 250 and the limiting rods 241, the top plate 240 can move and be positioned precisely inside the auxiliary groove 251, enabling position control to ensure that the top plate 240 does not shift or become unstable during the adjustment process, thus ensuring good contact between the top paper and the printer transmission system.

[0033] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0034] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
