Embodiment 1

[0034] as attached figure 1 Shown: The flattening device used in the production of the anti-myopia operation includes a frame 1, an upper flattening mechanism and a lower flattening mechanism, and the upper flattening mechanism includes an extrusion block 3 and a power mechanism for driving the extrusion block 3, such as figure 2 As shown, the extruding block 3 is vertically slidably connected with the frame 1 through the first chute 2, and the left end of the extruding block 3 is welded and fixed with a cross bar 4; the power mechanism here selects the cylinder 5, and the cylinder body of the cylinder 5 passes through the bolt (or prior art such as welding) is fixed with frame 1, and the piston rod 6 of cylinder 5 is fixed with cross bar 4 by bolt (or prior art such as welding), adopts cylinder 5 to drive extruding block 3 and vertically slides for existing technology, so I won’t go into details here. In the actual production process, if the power mechanism installed on one...

Embodiment 2

[0047] like Figure 5 As shown, the difference between the present embodiment and the first embodiment is that a buffer portion is provided between the squeeze roller 8 and the movable plate 7, and the buffer portion includes an elastic reset member 24. Here, a pressure spring is selected, and the squeeze roller 8 rotates coaxially. A pin rod 9 is connected, the middle part of the pin rod 9 is a round rod, and the outer diameter of the round rod is smaller than the inner diameter of the extrusion roller 8; the two ends of the pin rod 9 are integrally formed with a square, and the square passes through the third chute 23 and the movable plate 7 Vertical sliding connection, the upper end of the stage clip is welded with the block, and the lower end of the stage clip is welded with the bottom of the third chute 23 .

[0048] When in use, it is basically the same as in Embodiment 1. When the extrusion block moves down, it moves down to the position where it is pressed against the ...

Abstract

The invention relates to the technical field of production devices of homework books and particularly discloses a flattening device for production of a nearsightedness preventing homework book. The flattening device for production of the nearsightedness preventing homework book comprises a machine frame and a lower flattening mechanism. The lower flattening mechanism comprises a moving plate and squeezing rollers. The squeezing rollers are rotationally connected to the moving plate. The upper surfaces of the squeezing rollers are higher than the upper surface of the moving plate. The moving plate is horizontally connected to the machine frame in a sliding manner. The flattening device for production of the nearsightedness preventing homework book can solve the technical problem that in theprior art, since the squeezing action on the crease portion on the homework book is not enough, the crease portion is difficult to shape.

Description

technical field [0001] The invention relates to the technical field of production equipment for workbooks, and specifically discloses a flattening device for production of workbooks for preventing myopia. Background technique [0002] Existing workbooks are bound using a binding line (or staple) in the middle of the paper, and then the paper is folded along the position of the binding line to form a common workbook; The creases are flattened to ensure the quality of the workbook. The current flattening device adopts a crank-connecting rod structure, the pressing stroke and the pressure provided are fixed, and there is no pressure maintaining process, and the slider of the flattening device will return after running to the bottom dead center (maximum pressure). , the crease will lose pressure and rebound immediately, which directly affects the flattening quality. Contents of the invention [0003] The present invention intends to provide a flattening device for the produc...
