Technical Field

[0001] The present application relates to the field of printing, and in particular to a printing piece fixing frame. Background Art

[0002] Printing is a technology that uses processes such as plate making, inking, and pressurization to transfer ink to the surface of paper, textiles, plastics, leather, PVC, PC, and other materials to reproduce the contents of the original manuscript in batches.

[0003] During printing, the printed piece needs to be fixed to ensure the printing quality. However, the fixing parts of most existing devices are only suitable for specific sizes and cannot be adjusted. It is difficult to fix printed pieces of different sizes, resulting in increased costs. In addition, some printed pieces are prone to wrinkles, and the fixing devices of the prior art are difficult to remove the wrinkles, which affects the effect of subsequent printing, affecting production efficiency and quality.

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a printing piece fixing frame. Figure 1A printed piece fixing frame includes a frame-shaped support frame 1, so that the whole device is stably supported by the support frame 1, and two door-shaped moving plates 2 are slidably connected to the upper surface of the support frame 1, and two hydraulic cylinders 3 are fixedly connected to the lower surfaces of the two moving plates 2, and the inner walls of the two hydraulic cylinders 3 are slidably connected with piston rods 4, and the lower ends of the two piston rods 4 are fixedly connected to the upper surface of the arc-shaped wrinkle removal strip 5, so that the piston rods 4 are driven by the hydraulic cylinders 3 to drive the wrinkle removal strip 5 to move downward, so that the lower surface of the wrinkle removal strip 5 contacts the printed piece to be fixed, and then according to the printed piece, The size allows the two movable plates 2 to slide away from each other for a certain distance, thereby driving the two wrinkle removal strips 5 to slide away from each other, so that the two wrinkle removal strips 5 move in opposite directions on the upper surface of the printed piece, thereby removing wrinkles on the printed piece and flattening the printed piece, thereby improving the quality of the printed product. The opposite side surfaces of the two movable plates 2 are slidably connected with a plate-like pressing plate 6, so that after the wrinkles of the printed piece are removed by the two wrinkle removal strips 5, the two pressing plates 6 are moved downward to press the two sides of the printed piece to fix it, thereby preventing the movement of the printed piece from causing problems such as blurred pattern damage, thereby improving the printing quality.

[0023] Reference Figure 2 A first groove-shaped slide groove 7 is provided on the upper surface of the support frame 1, and a first columnar limiting column 8 is fixedly connected to the inner side wall of the first slide groove 7, and the outer surface of the first limiting column 8 slides relatively with the two movable plates 2. Secondly, a second groove-shaped slide groove 9 is provided on the upper surface of the support frame 1, and a double-headed screw 10 is rotatably connected to the inner side wall of the second slide groove 9, and the outer surface of the double-headed screw 10 is relatively screwed with the two movable plates 2, and one end of the double-headed screw 10 penetrates the support frame 1 to its side surface and is fixedly connected to the output end of the motor, so that under the limiting action of the first limiting column 8, the double-headed screw 10 is driven by the motor to rotate, thereby driving the two movable plates 2 to slide relative to or away from each other, so that the two movable plates 2 drive the two wrinkle removal strips 5 and the two pressing plates 6 to slide away from each other, and the printed part is dewrinkled by the two wrinkle removal strips 5 during the sliding process, and the sliding stops when sliding to both sides of the printed part, and the printed part is pressed and fixed by the two pressing plates 6.

[0024] Reference Figure 3A third groove-shaped slot 11 is provided on the side surface of the movable plate 2, and a columnar second limiting column 12 is fixedly connected to the inner top surface and the inner bottom surface of the third slot 11, and the outer surface of the second limiting column 12 slides relatively with the pressure plate 6. Secondly, a fourth groove-shaped slot 13 is provided on the side surface of the movable plate 2, and a ball screw 14 is rotatably connected to the inner top surface and the inner bottom surface of the fourth slot 13, and the outer surface of the ball screw 14 is relatively screwed with the pressure plate 6, and the upper end of the ball screw 14 passes through the movable plate 2 to its upper surface and is fixedly connected to the output end of the motor, so that under the limiting action of the second limiting column 12, the ball screw 14 is driven to rotate by the motor, thereby driving the two pressure plates 6 to move downward, so as to press and fix printed parts of different thicknesses.

[0025] Reference Figure 4 The cross-sectional width of the wrinkle removal strip 5 is smaller than the cross-sectional width of the movable plate 2, so when the pressing plate 6 slides up and down, the wrinkle removal strip 5 will not hinder the pressing plate 6, thereby ensuring the smooth sliding of the pressing plate 6.

[0026] The implementation principle of a printed piece fixing frame in the embodiment of the present application is as follows: first, the printed piece is laid flat on the upper surface of the support frame 1, and then, under the limiting action of the first limiting column 8, the double-headed lead screw 10 is driven by a motor to rotate, thereby driving the two movable plates 2 to slide relatively to the middle position of the support frame 1, and then, under the action of the hydraulic cylinder 3, the piston rod 4 is driven to drive the wrinkle removal strip 5 to move downward, so that the lower surface of the wrinkle removal strip 5 contacts the printed piece to be fixed, and then the double-headed lead screw 10 is driven by a motor to rotate, thereby driving the two movable plates 2 to slide away from each other to the two sides of the printed piece, and during the sliding process, the printed piece is wrinkled by the two wrinkle removal strips 5 to flatten the printed piece, thereby improving the quality of the printed product, and stopping sliding when sliding to the two sides of the printed piece, and under the limiting action of the second limiting column 12, the ball screw 14 is driven by a motor to rotate, thereby driving the two pressing plates 6 to move downward, so as to press and fix printed pieces of different thicknesses, and prevent problems such as blurred or damaged patterns caused by the movement of the printed piece, thereby improving the quality of printing.
