[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0031] like Figure 1As shown, a paper printing placement device for preventing the printing papers from being contaminated with each other comprises a placement rack 1, a placement mechanism, an I-shaped guide rail 5, and a placement guide support plate 4. The placement mechanism is provided with ten groups, which are fixedly connected to the placement rack 1 at equal intervals from top to bottom, and each group of the placement mechanism places a layer of paper; the I-shaped guide rail 5 is provided with two, which are vertically fixedly installed on the left and right side walls of the front end of the placement rack 1 by screws; the placement guide support plate 4 is correspondingly slidably installed on the two I-shaped guide rails 5, and under the guidance of the guide rails, the placement guide support plate 4 slides up and down to achieve front-to-back correspondence with any one of the ten groups of placement mechanisms, so as to assist in placing paper.

[0032] Furthermore, if Figures 2 to 5 As shown, each set of placement mechanisms includes a placement plate 2 and a pressure edge mechanism. The placement plate 2 includes a left side strip 21, a right side strip 22 and an air guide plate 26. The left side strip 21 is distributed along the front-to-back direction and is welded and fixed on the left side frame of the placement rack 1, and the right side strip 22 is distributed along the front-to-back direction and is welded and fixed on the right side frame of the placement rack 1; the upper plate surfaces of the left side strip 21 and the right side strip 22 are both stepped structures with a high front and a low back. Specifically, the upper plate surfaces of the left side strip 21 and the right side strip 22 are both composed of a front horizontal plate 23 and a rear horizontal plate 24. In order to prevent the stepped upper plate surfaces of the left side strip 21 and the right side strip 22 from scratching the paper, the front horizontal plate 23 and the rear horizontal plate 24 are transitionally connected by a transition inclined plate 25, so that when viewed from the side, the upper plate surfaces of the left side strip 21 and the right side strip 22 are Z-shaped structures with a high front and a low back.

[0033] The air guide plate 26 is fixedly connected between the inner plate wall of the left slat 21 and the inner plate wall of the right slat 22. The plate shape of the air guide plate 26 is consistent with the upper plate shape of the left slat 21 and the right slat 22, presenting a Z-shaped structure with high front and low back, and the rear end plate surface of the air guide plate 26 is inclined downward. Through the above arrangement, when the wind passes through the placement rack 1 from front to back, under the guidance of the air guide plate 26, the wind will dry the concave surface of the paper bending, avoiding the problem of insufficient drying caused by the concave surface of the paper due to the bending.

[0034] The edge pressing mechanism includes an edge pressing strip 3 and an edge pressing roller 31. Two edge pressing strips 3 are provided, which are symmetrically distributed above the left side strip 21 and the right side strip 22 in the front-to-back direction, and are correspondingly fixedly connected to the left side strip 21 and the right side strip 22. The lower plate surface of the edge pressing strip 3 is adapted to the upper plate surface of the left side strip 21 and the right side strip 22, and presents a Z-shaped structure with a low front and a high back. The pressing rollers 31 are provided with forty pieces, which are divided into four groups, each group has ten pieces, and the four groups of pressing rollers 31 are correspondingly arranged on the upper plate surface of the left side strip 21, the upper plate surface of the right side strip 22, and the lower plate surface of the two pressing strips 3; wherein, the frontmost and rearmost pressing rollers 31 in each group of ten pressing rollers 31 are driving wheels, and the rest are driven wheels; the pressing rollers 31 acting as driving wheels are used to provide driving force, so that the paper enters the pressing groove formed by the upper plate surface on which the left side strip 21 and the right side strip 22 are placed and the lower plate surface of the pressing strip 3, and since the paper is placed by relative rotation of the upper and lower pressing rollers 31, when the pressing rollers 31 acting as driving wheels stop rotating, the paper will also be relatively fixed, so that when the paper is placed on the left side strip 21 and the right side strip 22, it will not fall off easily.

[0035] like Figure 6 As shown, the placement guide tray 4 includes a left tray 41, a right tray 42, a connecting rod 43, and a connecting slide 44. The left tray 41 and the right tray 42 are connected as a whole through the connecting rod 43, and two connecting slides 44 are provided, which are connected to the left tray 41 and the right tray 42 respectively. The left tray 41 and the right tray 42 are slidably installed on the two I-shaped guide rails 5 through the connecting slides 44, and the connecting slides 44 have a tightening function. When the placement guide tray 4 is moved to the desired position on the I-shaped guide rail 5, the inner guide surface of the I-shaped guide rail 5 is tightened by the connecting slides 44 to achieve the position of the placement guide tray 4.

[0036] The use process of the present invention:

[0037] When in use, the placing guide support plate 4 moves to be flush with the position of the placing plate 2 of the lowest layer, and the newly printed paper is lifted and guided by the placing guide support plate 4, and the left and right sides of the paper enter between the left placing strip plate 21, the right placing strip plate 22 and the pressing strip plate 3, and under the rotation of the pressing roller 31 on the front side which acts as a driving wheel, enter the pressing groove formed by the upper plate surface of the left placing strip plate 21, the right placing strip plate 22 and the lower plate surface of the pressing strip plate 3. Since the pressing groove is a bent step-shaped structure and a limit is provided at the rear end, the pressing roller 31 which acts as a driving wheel can cooperate with the pressing roller 31 which acts as a driving wheel to press and fix the left and right sides of the paper to ensure that the paper does not fall off. After the paper on the current layer of placing plate 2 is placed, the placing guide support plate 4 moves up one layer, and the above placing process is repeated until the placing plate 2 on the placing rack 1 is fully filled with paper; after the paper is placed, the wind guiding effect of the wind guide plate 26 is used to dry the paper that is not completely dry.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
