[0020] The adjustable paper lifting and pressing mechanism for printing equipment, the threaded cooperation of the rotating screw and the movable screw frame allows accurate control of the height of the placement plate, realizes fine adjustment of the position of the printed paper, and adapts to printed papers of different thicknesses, while the movable screw frame ensures that no tilt or instability occurs during the lifting process.
[0021] The adjustable paper lifting and pressing mechanism for printing equipment can be used. The telescopic plate can be telescopically adjusted according to the lifting height of the lifting mechanism to meet different adjustment requirements, while preventing tilting or shaking during the lifting or lowering process. The anti-skid layer helps to ensure that the printed paper is stably attached to the placement plate by increasing the friction with the printed paper.
[0022] The adjustable paper lifting and pressing mechanism for printing equipment uses a stepping motor to drive the bidirectional screw to rotate precisely, thereby realizing fine position adjustment of the paper pressing mechanism.

At the same time, by starting the electric heating wire to heat the pressing plate, the paper fibers can be softened during the flattening process, and the elastic modulus of the paper can be reduced, thereby making it easier to iron out wrinkles and creases, thereby improving the efficiency of the flattening operation.
[0024] The adjustable paper lifting and pressing mechanism for printing equipment pre-expands the folded corners of the edge of the printed paper by blowing air through the flattening mechanism, which helps to ensure that the paper is in a relatively flat state before flattening, thereby reducing the resistance of the flattening mechanism during the flattening process, improving the efficiency of the flattening operation, and thus improving the final printing quality.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0036] See also Figures 1 to 7 The present invention provides a technical solution: an adjustable paper lifting and pressing mechanism for printing equipment, comprising a base 1, a driving mechanism 2 is rotatably connected to the middle of the top of the base 1, a lifting mechanism 3 is plugged into the inside of the driving mechanism 2, a placing plate 4 is provided at the top of the lifting mechanism 3, support frames 5 are provided on the left and right sides of the top of the base 1, an adjusting mechanism 6 is rotatably connected to the inner walls of the left and right sides of the supporting frame 5, a paper pressing mechanism 7 is threadedly connected to the bottom end of the adjusting mechanism 6, a blowing flattening mechanism 8 is horizontally penetrated inside the paper pressing mechanism 7, a slide rail 9 is provided in the middle of the top wall of the base 1, and a protective cover 10 is provided on the top of the base 1.
[0037] The paper pressing mechanism 7 includes an electric telescopic rod 701, a ventilation box 702 and a pressing plate 703. The top of the electric telescopic rod 701 is connected to the bottom end of the movable screw seat 603. The driving end of the electric telescopic rod 701 is provided with a ventilation box 702. The bottom of the ventilation box 702 is provided with a pressing plate 703. The inner wall interlayer of the pressing plate 703 is provided with an electric heating wire 704. It should be noted that when the operator needs to flatten the printed paper, the electric telescopic rods 701 on the left and right sides can be started simultaneously through an external controller, and the driving ends thereof extend downward, and push the ventilation box 702 and the pressing plate 703 connected thereto to descend together until the bottom of the pressing plate 703 can be closely attached to the surface of the printed paper. At the same time, the adjusting mechanism 6 is started again, so that the paper pressing mechanisms 7 on the left and right sides can move from the middle to both sides along the thread direction of the bidirectional screw 601. During this period, the pressing plate 703 will be attached to the surface of the printed paper for flattening. , thereby pushing out the wrinkled part of the printed paper, and in actual use, the electric telescopic rod 701 can automatically adjust the height of the pressing plate 703 to achieve automatic flattening of the printed paper, so that the paper pressing mechanism 7 can adapt to printed papers of different thicknesses and provide a consistent flattening effect, thereby improving the flexibility and applicability of the equipment. At the same time, through the precise control of the electric telescopic rod 701, the pressure applied by the pressing plate 703 on the printed paper can be finely adjusted to ensure the flattening effect while avoiding damage to the paper. Before the adjustment mechanism 6 starts working, the electric telescopic rod 701 first pushes the pressing plate 703 downward to make it fit closely to the surface of the printed paper to provide initial pressure for the subsequent flattening operation. While the adjustment mechanism 6 pushes the paper pressing mechanism 7 to move from the middle to both sides, its pressing plate 703 can be close to the surface of the printed paper to help flatten the wrinkles on the paper, thereby helping to maintain the flatness of the paper during operation.
[0038] The operator starts the adjustment mechanism 6 to drive the paper pressing mechanisms 7 on the left and right sides to push from the middle to the two sides. During this period, the pressing plate 703 will be pressed against the surface of the printing paper. At the same time, the operator can start the electric heating wire 704 provided in the inner wall interlayer of the pressing plate 703 to heat the entire pressing plate 703, so that the pressing plate 703 can iron the folds and wrinkles on the surface of the printing paper at a high temperature. In actual use, by starting the electric heating wire 704 to heat the pressing plate 703, the paper fibers can be softened during the flattening process, and the elastic modulus of the paper can be reduced, so that the wrinkles and creases can be ironed more easily, and the efficiency of the flattening operation can be improved, which helps to improve the quality of the final printed product. When the pressing plate 703 is in a heated state, the paper is more easily flattened, thereby reducing the pressure required to be applied and reducing the risk of paper tearing or damage caused by excessive pressure. By adjusting the power of the electric heating wire 704, the temperature of the pressing plate 703 can be accurately controlled, so that it can adapt to different types of paper and printing requirements.
[0039] The blowing mechanism 8 includes an air pump 801, an air pipe 802, a shunt pipe 803 and a spraying pipe 804. The outlet end of the air pump 801 is connected to the inner wall of one side of the ventilation box 702 and is connected to the through hole opened therein. The air outlet end of the air pump 801 is plugged with the air pipe 802, and the air outlet end of the air pipe 802 is provided with a shunt pipe 803, and the air outlet end of the shunt pipe 803 is provided with a spraying pipe 804. It should be noted that when the paper pressing mechanism 7 is used to push the printed paper flat, the operator can start the air pump 801 at the same time, so that the air pump 801 draws external air into the air pipe 802 through the through hole opened in the ventilation box 702, and pushes the air along the air pipe 802 into the shunt pipe 803, and then enters the shunt pipe 803. It enters into several spraying and sweeping pipes 804 and quickly sprays to the outside along the pipes, so that the folded corners at the corners of the printed paper can be blown open in advance, which can facilitate the flattening operation of the pressing plate 703. In actual use, the folded corners of the edge of the printed paper can be pre-opened by blowing air through the flattening mechanism 8, which helps to ensure that the paper is in a relatively flat state before flattening, thereby reducing the resistance of the paper pressing mechanism 7 during the flattening process, improving the efficiency of the flattening operation, and thus improving the final printing quality. The flattening mechanism 8 can pre-process the edge of the paper without directly contacting the paper, thereby reducing physical damage to the paper during the flattening process. The flattening mechanism 8 can be linked with the paper pressing mechanism 7 to realize automatic processing, reduce manual intervention, and improve the overall automation level of the operation.
[0040] In this embodiment, Figure 2 and Figure 7 As shown, the driving mechanism 2 includes a driving motor 201, a driving gear 202, a driven gear 203 and a rotating shaft 204. The bottom end of the rotating shaft 204 is inserted into the inside of the driving gear 202 and is rotatably connected to the top of the base 1. The top end of the rotating shaft 204 is inserted with the driving motor 201, and the outer side of the driving gear 202 is meshed with a plurality of driven gears 203.
[0041] The driven gear 203 is meshed with the driving gear 202 through the outer teeth, and the driving motor 201 is rotated with the driving gear 202 through the rotating shaft 204. The diameter of the driving gear 202 is larger than that of the driven gear 203, and the number of teeth of the driving gear 202 is more than that of the driven gear 203. It should be noted that the operator can first place the printing paper flat on the top of the placement plate 4, and then start the driving motor 201 according to actual needs to drive the rotating shaft 204 plugged therein to start rotating, and the driving gear 202 connected thereto rotates synchronously, and at the same time, the four The driven gear 203 and the rotating screw 302 inserted into the inner wall of the driven gear 203 will also be driven to rotate together, thereby driving the entire placement plate 4 to perform a lifting operation. In actual use, the driving motor 201 can accurately control the rotation speed and direction of the rotating shaft 204, thereby achieving precise control of the lifting operation of the placement plate 4, and by changing the rotation speed of the driving motor 201, the lifting speed and height of the placement plate 4 can be easily adjusted, and through the gear transmission of the driving gear 202 and the driven gear 203, synchronous rotation can be achieved, thereby ensuring the consistency and coordination of the lifting and lowering movement of the lifting mechanism 3, and improving the transmission efficiency of the mechanism.
[0042] In this embodiment, Figure 2 and Figure 6 As shown, the lifting mechanism 3 includes a movable screw frame 301 and a rotating screw 302, the bottom end of the rotating screw 302 is inserted into the interior of the driven gear 203 and is rotatably connected to the top four corners of the base 1, the inner wall of the movable screw frame 301 is screwed to the outer wall of the rotating screw 302, and a placement plate 4 is welded to the top of the movable screw frame 301.
[0043] The placement plate 4 forms a vertical movement structure through the moving screw frame 301 and the rotating screw rod 302, and the rotating screw rod 302 forms a rotating structure with the base 1 through the driven gear 203; it should be noted that when the operator starts the driving motor 201 to drive the driving gear 202 to rotate, so that the driven gear 203 meshed with the outer wall of the driving gear 202 is also rotated, at this time, the rotating screw rod 302 connected to its inner wall will also be driven to rotate together, so that the moving screw frame 301 screwed to the outer wall of the rotating screw 302 can move up and down along the thread direction, thereby pushing the placement plate 4 arranged at the top thereof to move together Lifting and lowering, thereby achieving height adjustment, and in actual use, the threaded cooperation between the rotating screw 302 and the movable screw frame 301 allows precise control of the height of the placement plate 4, thereby achieving fine adjustment of the position of the printed paper, and then can adapt to printing papers of different thicknesses and meet diverse printing needs, wherein the movable screw frame 301 provides a stable platform that can bear the weight of the printing paper and the placement plate 4, ensuring that no tilting or instability occurs during the lifting process, and through the continuous rotation of the rotating screw 302, the movable screw frame 301 can achieve stepless adjustment, thereby providing smooth and continuous height changes.
[0044] In this embodiment, Figure 2 and Figure 6 As shown, telescopic plates 401 are provided on the left and right sides of the bottom of the placement plate 4, and an anti-slip layer 402 is provided on the top of the placement plate 4; it should be noted that when the operator starts the driving mechanism 2 to drive the rotating screw 302 to rotate, the movable screw frame 301 screwed to the outer wall of the rotating screw 302 will be connected with the placement plate 4 arranged on the top thereof, and move up and down along the thread direction, and during this period, the telescopic plates 401 welded to the left and right sides of the bottom of the placement plate 4 will also be driven to extend or shorten together, thereby providing stable support for the lifting and lowering operation of the entire placement plate 4, and in actual use, the telescopic plate 401 can be telescoped and adjusted according to the lifting height of the lifting mechanism 3 to adapt to different adjustment requirements, thereby increasing the lateral stability of the placement plate 4, preventing tilting or shaking during the lifting or lowering process, and providing additional stable support for the placement plate 4 in the entire lifting process, thereby ensuring the stable and stable placement of printed paper.
[0045] When the operator flattens the printed paper, he needs to first place the printed paper horizontally on the top of the placement plate 4 so that it contacts the anti-skid layer 402. During the period of using the lifting mechanism 3 to adjust the height of the entire placement plate 4 and using the paper pressing mechanism 7 to flatten the wrinkles on the entire surface of the printed paper, in actual use, the anti-skid layer 402 increases the friction with the printed paper, so that when the lifting mechanism 3 adjusts the height of the placement plate 4, the anti-skid layer 402 ensures that the printed paper is stably attached to the placement plate 4, so that it will not move due to vibration or slipping, and the anti-skid layer 402 also helps to improve the accuracy of paper placement and flattening. At the same time, the anti-skid layer 402 has a certain softness, which can reduce the scratches or damages to the paper surface by the placement plate 4 to a certain extent.
[0046] In this embodiment, Figure 2 and Figure 3 As shown, the adjustment mechanism 6 includes a bidirectional screw 601, a stepper motor 602 and a movable screw seat 603. The left and right ends of the bidirectional screw 601 are rotatably connected to the left and right inner walls of the protective cover 10. The output end of the stepper motor 602 is plugged into one end of the bidirectional screw 601, and the movable screw seat 603 is screwed to the outer wall of the bidirectional screw 601.
[0047] The bidirectional screw 601 and the stepper motor 602 form a rotating structure, the movable screw seat 603 is divided into two left and right parts, and the inner walls of the two parts are provided with threads corresponding to the thread directions on the left and right sides of the bidirectional screw 601, and the movable screw seat 603 is slidably connected with the slide rail 9; it should be noted that when the operator needs to start the paper pressing mechanism 7 to flatten the printed paper, the stepper motor 602 can be started first, so that the output end of the stepper motor 602 drives the bidirectional screw 601 connected thereto to start rotating, so that the movable screw seat 603 screwed to the two sides of the outer wall of the bidirectional screw 601 can drive the paper pressing mechanism 7 arranged at its bottom to move closer to or away from each other along the respective thread directions, thereby realizing the flattening operation of pushing from the middle to both sides. In actual use, the stepper motor 602 can provide precise rotation control so that the bidirectional screw 601 can be accurately rotated, thereby realizing fine position adjustment of the paper pressing mechanism 7. Since the movable screw seat 603 is threadedly connected to the bidirectional screw 601, when the stepper motor 602 drives the bidirectional screw 601 to rotate, the left and right movable screw seats 603 can synchronously approach or move away from each other along the thread direction, thereby ensuring the synchronous movement of the paper pressing mechanisms 7 on both sides, ensuring that the paper pressing mechanisms 7 on both sides apply uniform pressure to the paper, avoiding uneven indentations or damage to the paper, and realizing efficient flattening operation. At the same time, the adjustment mechanism 6 can be adjusted according to the width and size of the paper, and can adapt to printing papers of different sizes.
[0048] The use method of the present invention: When the adjustable paper lifting and pressing mechanism for printing equipment is used, the working process is as follows:
[0049] like Figures 1 to 7 As shown, first, the operator flattens the printed paper. The operator needs to place the printed paper horizontally on the top of the placement plate 4 so that it contacts the anti-slip layer 402. Then, according to actual needs, the driving motor 201 can be started to drive the rotating shaft 204 plugged therein to start rotating, and the driving gear 202 sleeved therewith can be rotated synchronously. At the same time, the four driven gears 203 meshed with the outer wall of the driving gear 202 and the rotating screw 302 plugged into the inner wall of the driven gear 203 will also be driven to rotate together, so that the moving shaft 204 screwed to the outer wall of the rotating screw 302 The movable screw frame 301 can move up and down along the direction of the thread, thereby pushing the placement plate 4 arranged at the top thereof to rise and fall together, thereby realizing height adjustment. During this period, the telescopic plates 401 welded to the left and right sides of the bottom of the placement plate 4 will also be driven to extend or shorten together, thereby providing stable support for the lifting operation of the entire placement plate 4, and then the electric telescopic rods 701 on the left and right sides are simultaneously started through the external controller, and the driving ends thereof extend downward, and push the ventilation box 702 and the pressing plate 703 connected thereto to descend together, until the bottom of the pressing plate 703 can At the same time, the stepper motor 602 is started, so that its output end drives the bidirectional screw 601 plugged therein to start rotating, so that the movable screw seat 603 screwed on both sides of the outer wall of the bidirectional screw 601 can drive the paper pressing mechanism 7 arranged at its bottom to move closer to or away from each other along the direction of their respective threads, thereby realizing the flattening operation of pushing from the middle to both sides. At the same time, the electric heating wire 704 arranged in the inner wall interlayer of the pressing plate 703 is started to heat the entire pressing plate 703, so that the pressing plate 703 is in a The folds and wrinkles on the surface of the printed paper are ironed out in a high temperature state, and the vacuum pump 801 is started at the same time, so that the vacuum pump 801 draws external air into the air pipe 802 through the through holes opened in the ventilation box 702, and pushes the air along the air pipe 802 into the diversion pipe 803, and then along the diversion pipe 803 into the interior of several spraying and sweeping pipes 804, and quickly sprays to the outside along the pipeline, so as to blow open the folded corners at the edges of the printed paper one step in advance, and then facilitate the flattening operation of the pressing plate 703.
