[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 3As shown, an anti-falling mechanism of a flat creasing and creasing cutting machine described in an embodiment of the present invention comprises a body 1; a flip pressing plate 12 is installed in the middle of the body 1; a fixed pressing plate 13 is fixedly connected to the side wall of the body 1; the side wall of the flip pressing plate 12 is symmetrically arranged and slidably connected to a pair of baffles 14; a first groove 15 is opened in the middle of the baffle 14; a paper pressing strip 16 is slidably connected to the middle of the first groove 15; a first spring 17 is installed inside the first groove 15; when working, the distance between the pair of baffles 14 is adjusted to be slightly larger than the length of the fixed pressing plate 13, and then the cardboard to be processed is placed between the pair of baffles 14, and the cardboard is located between the pair of paper pressing strips 16 and the flip pressing plate 12, and then the machine is started to make the flip pressing plate 12 and the fixed The pressing plate 13 approaches to process the cardboard. In the process of the flipping pressing plate 12 moving toward the fixed pressing plate 13, the two sides of the fixed pressing plate 13 will squeeze the inclined surfaces of the end of the pressing paper strip 16, so that the pressing paper strip 16 will retract into the inside of the first groove 15, reducing the obstruction to the cardboard processing. When the flipping pressing plate 12 and the fixed pressing plate 13 are separated, the end of the pressing paper strip 16 will be ejected from the inside of the first groove 15 by the first spring 17 as the fixed pressing plate 13 leaves, thereby limiting the cardboard and restricting the cardboard between the pressing paper strip 16 and the flipping pressing plate 12 again, thereby reducing the situation where the cardboard floats away from the side wall of the flipping pressing plate 12 and then detaches due to the airflow generated by the negative pressure. Through the above structure, the situation where the cardboard falls off due to the airflow after processing can be reduced.

[0024] like Figures 1 to 3As shown, the middle part of the first groove 15 is slidably connected with a shovel paper strip 2; the cross-sectional length of the shovel paper strip 2 is slightly larger than the cross-sectional length of the pressure paper strip 16; the middle part of the first groove 15 is fixedly connected with a partition plate 21; the partition plate 21 is located between the pressure paper strip 16 and the shovel paper strip 2; the side walls of the shovel paper strip 2 and the pressure paper strip 16 are fixedly connected with a connecting belt 23; the other end of a pair of connecting belts 23 is fixedly connected to a first sliding plate 22; the first sliding plate 22 is slidably connected to the inside of the first groove 15; the first spring 17 is located on the side of the first sliding plate 22 away from the connecting belt 23, and the first spring 17 is arranged close to the pressure paper strip 16 away from the shovel paper strip 2; when the paperboard is not pressed by the fixed pressing plate 13, the first spring 17 will be in a resilient state, thereby pressing the connecting belt 23 against the end of the partition plate 21 and rotating with the connecting belt 23 as the axis, so that the pressure paper strip 16 extends out of the inside of the first groove 15, and at the same time, the first sliding plate 22 is provided with an end of the shovel paper strip 2 due to the lever The principle is to deflect toward the depth of the first groove 15, and then pull the end of the shoveling paper strip 2 into the inside of the first groove 15, so that the fixed pressure plate 13 can press the paperboard normally. When the fixed pressure plate 13 presses the paperboard, the fixed pressure plate 13 squeezes the paperboard strip 16, so that the paperboard strip 16 and the first sliding plate 22 slide toward the inside of the first groove 15. When the paperboard processing is completed, the fixed pressure plate 13 and the flip pressure plate 12 are away from each other, and the shoveling paper strip 2 will be separated from the fixed pressure plate under the elastic force of the first spring 17. The first spring 17 pushes the cardboard strip 2 out of the first groove 15, so that when the cardboard is attached to the side wall of the fixed pressure plate 13 due to air pressure, the cardboard is shoveled off from the side wall of the fixed pressure plate 13 and returned to the side wall of the flip pressure plate 12. With the above structure, when the cardboard is attached to the side wall of the fixed pressure plate 13 after processing, the cardboard can be shoveled off from the side wall of the fixed pressure plate 13, thereby reducing the occurrence of cardboard falling off.

[0025] like Figures 1 to 3As shown, a second groove 3 is provided inside the blocking bar 14; an air inlet groove 31 is provided on the side wall of the second groove 3; a second sliding plate 32 is slidably connected to the inside of the second groove 3; a plurality of sliding posts 33 are fixed to the top of the second sliding plate 32; a plurality of the sliding posts 33 are arranged through the top of the second groove 3; a plurality of second springs 34 are installed on the bottom of the second sliding plate 32; a plurality of exhaust holes 35 are provided on the side wall of the second groove 3; a plurality of the exhaust holes 35 are arranged above the shoveling paper strip 2; during operation, when the paperboard is being pressed, the sliding posts 33 will be squeezed by the side wall of the machine body 1 and drive the second sliding plate 32 to slide. The external air enters the interior of the second groove 3 through the air inlet groove 31. After the cardboard is processed, the flip pressing plate 12 is separated from the fixed pressing plate 13. At this time, the second sliding plate 32 will squeeze the air inside the second groove 3 through the air inlet groove 31 and the exhaust hole 35 under the elastic force of the second spring 34. The air discharged from the exhaust hole 35 can blow a gap between the cardboard attached to the side wall of the fixed pressing plate 13 and the fixed pressing plate 13, so that a large amount of external air can flow in through the gap, reducing the tightness between the fixed pressing plate 13 and the cardboard due to negative pressure, so that the shoveling paper strip 2 can more easily shovel the cardboard off the side wall of the fixed pressing plate 13.

[0026] like Figures 1 to 4 As shown, an elastic membrane 4 is fixedly connected to the side wall of the second groove 3; the elastic membrane 4 covers the air inlet groove 31; a pair of air vents 41 are opened in the middle of the elastic membrane 4; a fixing plate 42 is fixedly connected to the side of the elastic membrane 4 facing the air inlet groove 31; during operation, external air will enter the interior of the second groove 3 through the air vents 41. During exhaust, the elastic membrane 4 will be impacted by the air flow and squeezed toward the air inlet groove 31, causing the fixing plate 42 to block the air inlet groove 31, thereby making it difficult for the internal gas of the second groove 3 to be discharged from the air inlet groove 31, thereby increasing the airflow intensity ejected from the multiple exhaust holes 35.

[0027] like Figures 1 to 3 As shown, a plurality of first magnets 5 are fixed to the top of the baffle 14; the slide column 33 is slidably connected to the inside of the first magnet 5; the top of the slide column 33 is fixed to the second magnet 51; the second magnet 51 and the first magnet 5 are set to repel each other; the repulsive force between the first magnet 5 and the second magnet 51 increases the discharge speed of the gas inside the second slot 3, thereby further increasing the airflow intensity of the gas ejected from the exhaust hole 35.

[0028] like Figures 1 to 2As shown, the bottom of the baffle 14 is threadedly connected with an adjusting bolt 6; the end of the adjusting bolt 6 passes through the side wall of the baffle 14 and contacts the side wall of the flip pressure plate 12; after completing the position adjustment of a pair of baffles 14, the friction between the baffle 14 and the flip pressure plate 12 is increased by rotating the adjusting bolt 6, so that the baffle 14 is difficult to slide on the side wall of the flip pressure plate 12, thereby reducing the occurrence of the baffle 14 offsetting when the equipment is running.

[0029] like Figure 3 As shown, a filter screen 7 is fixed to the side wall of the baffle 14; the filter screen 7 is located at the end of the plurality of exhaust holes 35; through the above structure, the occurrence of cardboard scraps generated during processing entering the exhaust holes 35 can be reduced.

[0030] During operation, the distance between the pair of stop bars 14 is adjusted to be slightly larger than the length of the fixed pressing plate 13, and then the cardboard to be processed is placed between the pair of stop bars 14, and the cardboard is located between the pair of cardboard pressing strips 16 and the flip pressing plate 12, and then the machine is started to make the flip pressing plate 12 and the fixed pressing plate 13 close to each other for processing the cardboard. In the process of the flip pressing plate 12 moving toward the fixed pressing plate 13, the two sides of the fixed pressing plate 13 will squeeze the inclined surface of the end of the cardboard pressing strip 16, so that the cardboard pressing strip 16 is retracted into the inside of the first groove 15, reducing the obstruction to the cardboard processing. When the flip pressing plate 12 and the fixed pressing plate 13 are separated, the end of the cardboard pressing strip 16 will be pulled out of the first groove 15 by the first spring 17 as the fixed pressing plate 13 leaves. The cardboard is then restricted between the cardboard pressing strip 16 and the flipping plate 12 again, thereby reducing the situation in which the cardboard floats away from the side wall of the flipping plate 12 and then detaches due to the airflow generated by the negative pressure. When the cardboard is not pressed by the fixed pressing plate 13, the first spring 17 will be in a resilient state, thereby pressing the connecting belt 23 against the end of the partition plate 21 and rotating with the connecting belt 23 as the axis, so that the cardboard pressing strip 16 extends out of the first groove 15. At the same time, the end of the shoveling strip 2 provided on the first sliding plate 22 will deflect toward the depth of the first groove 15 due to the lever principle, and then pull the end of the shoveling strip 2 into the first groove 15, so that the fixed pressing plate 13 can press the cardboard normally. When pressing the cardboard, the fixed pressure plate 13 squeezes the pressure paper strip 16, so that the pressure paper strip 16 and the first sliding plate 22 slide toward the inside of the first groove 15. When the cardboard processing is completed and the fixed pressure plate 13 is moving away from the flip pressure plate 12, the scraping paper strip 2 will contact the side wall of the fixed pressure plate 13 under the elastic force of the first spring 17, and when the pressing surface of the fixed pressure plate 13 is separated from the top surface of the scraping paper strip 2, the scraping paper strip 2 will be pushed out of the inside of the first groove 15 by the first spring 17, so that when the cardboard is attached to the side wall of the fixed pressure plate 13 due to air pressure, the cardboard is shoveled from the side wall of the fixed pressure plate 13 back to the side wall of the flip pressure plate 12. When the cardboard is pressed, the sliding column 33 will be squeezed by the side wall of the machine body 1 and drive the second sliding plate 32 to slide. The second sliding plate 32 will squeeze the gas inside the second groove 3 through the air inlet groove 31 and the exhaust hole 35 under the elastic force of the second spring 34, and the gas discharged from the exhaust hole 35 can blow a gap between the cardboard attached to the side wall of the fixed pressing plate 13 and the fixed pressing plate 13, and the external air flow will enter the interior of the second groove 3 through the vent 41. When exhausting, the elastic membrane 4 will be impacted by the air flow and squeezed toward the air inlet groove 31, so that the fixed plate 42 blocks the air inlet groove 31, thereby making it difficult for the gas inside the second groove 3 to be discharged from the air inlet groove 31. After the position adjustment of the pair of baffles 14 is completed,The friction between the stop bar 14 and the flip pressure plate 12 is increased by turning the adjusting bolt 6.
