Description

Technical Field

[0001] The utility model relates to the technical field of paper storage, in particular to a printing paper placing rack that is easy to use. Background Art

[0002] Printing paper is a general term for paper used for various printed materials, such as letterpress paper, offset printing paper, high-grade glossy cardboard, newsprint, writing paper, etc. Its characteristics are good printing adaptability and high opacity. In order to facilitate the use of printing paper during use, the printing paper will be placed on a rack. On the one hand, it is easy to use, and on the other hand, it can prevent the printing paper from getting damp.

[0003] A Chinese patent discloses a paper placement rack for printing (CN211812466U), which relates to the field of printing technology, including a base frame, two symmetrical guide rings are fixedly installed on the back of the base frame, and two symmetrical support columns are placed at the rear of the base frame. The paper placement rack for printing pulls the fixed frame upward to move, pushes the return spring 1 to compress through the sliding ring, places the stacked paper between the base frame and the pressure plate, releases the fixed frame, and pushes the pressure plate to better press the paper through the return tension of the return spring 1. When the placed paper is thicker, when the sliding ring moves up to the limit position, the support column is pulled to continue moving upward in the guide ring, and the return spring 2 is compressed. When the pressing is released, the return tension of the return spring 2 is used to improve the pressing effect on the paper. When the paper is wider, the auxiliary plate is pulled out to both sides, so as to better adjust the pressing area of ​​the paper, thereby improving the adjustment and pressing effect of the device. Most of the current printing paper racks are fixed. Therefore, when placing printing papers of different sizes, the papers may shake on the rack due to unstable paper limit, which may easily cause the papers to be worn or the edges of the papers to be damaged. Therefore, an easy-to-use printing paper rack is provided. Utility Model Content

[0021] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended drawings of the embodiment of the utility model. Figure 1-4 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0022] like Figure 1-4 As shown: This embodiment provides a convenient printing paper placement rack, including a placement box 1, both side walls of the placement box 1 are provided with paper taking slots 2, a lifting component 3 is provided on the inner wall of the bottom surface of the placement box 1, and a limit component 4 is provided on the inner wall of the lifting component 3;

[0023] The limit assembly 4 includes a travel groove 41, a positioning hole 42 and a sliding block 43. The outer surface of the sliding block 43 is slidably connected to the inner wall of the travel groove 41. A moving rod 44 is fixedly installed on the upper surface of the sliding block 43. A limiting rod 45 is fixedly installed on the upper surface of the moving rod 44. A groove is provided on the lower surface of the moving rod 44. A positioning spring 48 is fixedly installed on the inner wall of the groove. A positioning rod 49 is fixedly installed on one end of the positioning spring 48. The positioning rod 49 is adapted in size to the positioning hole 42. A moving rack 46 is fixedly installed on the lower surface of the sliding block 43. A transmission gear 47 is meshed with the moving rack 46.

[0024] The specific implementation method is as follows: the moving rod 44 is moved on the upper surface of the placement plate 32 through the limiting rod 45. After the moving rod 44 moves to a position with the same size as the printed paper, the positioning rod 49 is embedded in the positioning hole 42 under the action of the positioning spring 48, thereby fixing the moving rod 44.

[0025] The lifting assembly 3 includes a telescopic spring 31, one end of the telescopic spring 31 is fixedly connected to the inner wall of the bottom surface of the placement box 1, and the other end of the telescopic spring 31 is fixedly installed with a placement plate 32. A ball 33 is movably installed on the upper surface of the placement plate 32. The outer surface of the placement plate 32 is slidably connected to the inner wall of the placement box 1. The travel groove 41 and the positioning hole 42 are both arranged outside the upper surface of the placement plate 32. There are two travel grooves 41. One end of the sliding block 43 extends to the inside of the placement plate 32. The transmission gear 47 is rotatably connected to the inner wall of the bottom surface of the placement plate 32 through a rotating shaft.

[0026] The specific implementation method is as follows: the printed paper is placed on the placement plate 32, at which time the paper and the ball 33 are in contact, and the placement plate 32 is squeezed into the placement box 1 by the gravity of the printed paper. At this time, the telescopic spring 31 is in a compressed state, and the placement box 1 will limit the two sides of the printed paper, and the limit rod 45 will limit the other two sides of the printed paper. When it is necessary to take the paper, the printed paper on the placement plate 32 is taken through the paper taking slot 2. As the amount of printed paper on the placement plate 32 decreases, the placement plate 32 will gradually move up under the action of the telescopic spring 31, thereby facilitating the taking of the printed paper at the bottom of the placement box 1.

[0027] Working principle: The moving rod 44 is moved on the upper surface of the placement plate 32 through the limit rod 45. After the moving rod 44 moves to a position with the same size as the printed paper, the positioning rod 49 will be embedded in the positioning hole 42 under the action of the positioning spring 48, so that the moving rod 44 is fixed, and then the printed paper is placed on the placement plate 32. At this time, the paper and the ball 33 are in contact, and the placement plate 32 is squeezed into the placement box 1 by the gravity of the printed paper. At this time, the telescopic spring 31 is in a compressed state, and the placement box 1 will limit the two sides of the printed paper, and the limit rod 45 will limit the other two sides of the printed paper. When it is necessary to take paper, the printed paper on the placement plate 32 is taken through the paper taking slot 2. As the printed paper on the placement plate 32 decreases, the placement plate 32 will gradually move up under the action of the telescopic spring 31, so as to facilitate the taking of the printed paper at the bottom of the placement box 1.

[0028] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0029] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
