Description

Technical Field

[0001] The utility model relates to a pre-stack paper mechanism, in particular to a new type of dual-purpose pre-stack paper mechanism. Background Art

[0002] The Chinese utility model patent with the publication number of CN213170712U discloses a printing material feeding mechanism of a screen printing machine. The pre-stack support is connected after the main stack support. The printing materials are pre-stacked on the pre-stack support in advance. After the main stack support descends in place, the pre-stacked printing materials on the pre-stack support are pushed onto the main stack support. The roller shaft for rolling and pushing the paper stack is unreliable. Moreover, due to different previous processes (such as die cutting, offset printing), customers will also directly load the paper with a forklift, and the pre-stack support cannot be directly adapted. Content of the Utility Model

[0003] In view of the technical problems existing in the background art, the utility model aims to provide a new type of dual-purpose pre-stack paper mechanism, which adopts a longitudinal paper transfer guide rail and a ramp plate, and can not only perform pre-stack paper but also adapt to direct paper loading by a forklift.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: The new type of dual-purpose pre-stack paper mechanism includes a frame, a paper loading station and a paper stacking station. The paper loading station is equipped with a paper stacking table board, and the paper stacking table board is arranged to be lifted and lowered on the frame. The paper stacking table board is provided with a longitudinal guide rail groove. The paper stacking station is equipped with a longitudinal paper transfer guide rail and a positioning stop. The longitudinal paper transfer guide rail is connected with the longitudinal guide rail groove. The positioning stop is arranged to be adjusted horizontally. The positioning stop is located between the paper loading station and the paper stacking station. A ramp plate is arranged between the longitudinal paper transfer guide rails.

[0005] In this solution, when directly loading the paper with a forklift, the distance between the positioning stops is adjusted to the maximum. The forklift reaches the paper stacking table board from the ramp plate. After putting down the paper stack, the forklift exits. When performing pre-stack paper, the paper stacking trolley reaches the paper stacking station through the longitudinal paper transfer guide rail, and the distance between the positioning stops is adjusted corresponding to the width of the paper. The paper is aligned and stacked on the paper stacking trolley with the positioning stop as a reference. After the empty paper stacking trolley at the paper loading station exits, the paper stacking trolley with the stacked paper at the paper stacking station reaches the paper loading station along the longitudinal guide rail groove.

[0006] Preferably, the frame is provided with a horizontal adjustment chute and a horizontal adjustment shaft. The horizontal adjustment shaft is located above the horizontal adjustment chute. The lower end of the positioning stop is horizontally slidably arranged in the horizontal adjustment chute, and the upper end of the positioning stop is horizontally movably adjusted on the horizontal adjustment shaft.

[0007] In this solution, the horizontal adjustment chute guides the adjustment of the positioning stop. The positioning stop is slidably and positionedly connected with the horizontal adjustment shaft, and the adjustment is convenient.

[0008] Preferably, a platen frame is arranged on the machine frame in a lifting manner, and the paper stacking platen is arranged on the platen frame in a laterally movable and adjustable manner.

[0009] In this solution, when the paper on the paper stacking platen reaches the printing position and there is a large difference between the left and right, the paper stacking platen can be laterally moved and adjusted.

[0010] Preferably, the platen frame is connected with an adjusting screw rod in a threaded manner. One end of the adjusting screw rod is connected with a handwheel, and the other end of the adjusting screw rod is connected with the paper stacking platen.

[0011] In this solution, the handwheel drives the adjusting screw rod to rotate, driving the paper stacking platen to move laterally relative to the platen frame, which is convenient for adjustment.

[0012] Preferably, a connecting plate is arranged between the longitudinal paper transfer guide rail and the machine frame, and a paper stacking trolley is connected between the paper loading station and the paper stacking station.

[0013] In this solution, the connecting plate can enhance the connection between the longitudinal moving guide rail and the machine frame, enabling the paper stacking trolley to smoothly reach the position of the paper stacking platen through the longitudinal moving guide rail.

[0014] The beneficial effect of the present utility model is that when directly loading paper with a forklift, the forklift reaches the paper loading station from the ramp plate. When pre-stacking paper, the paper stacking trolley that has completed paper stacking at the paper stacking station reaches the paper stacking platen along the longitudinal guide rail groove, taking into account both paper loading methods and adapting to different previous processes. Therefore, the present utility model has substantial features and progress compared with the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
