[0023] The present invention provides a feeding mechanism with a double limit structure for a printing press, which has the following beneficial effects:

The rolling friction provided by the rolling mechanism has lower energy consumption, reducing the resistance of the paper during the transportation process, helping to reduce the energy consumption of the entire transportation process and at the same time improving the transportation efficiency.
[0025] The printing press uses a feeding mechanism with a double limit structure. The clamping mechanism can achieve precise lateral clamping, and the lifting and lowering operation of the second clamping plate can be adjusted according to the actual thickness of the printed paper, so that the clamping mechanism can adapt to papers of different thicknesses. The stable clamping provided by the clamping mechanism can prevent the paper from moving or misaligning during transmission.
[0026] The printing press uses a feeding mechanism with a double limit structure, which can drive the second clamping plate to automatically adjust its vertical height through an adjustment mechanism, so as to adapt to printing papers of different thicknesses, thereby improving the adaptability and flexibility of the equipment. The extension of the telescopic baffle can keep pace with and work in coordination with the first clamping plate and the second clamping plate, thereby ensuring precise side clamping and limiting of the printing paper, which can improve the accuracy of paper positioning and increase the contact area between the clamping mechanism and the printing paper, thereby enhancing the stability of the clamping mechanism in clamping the side edges of the printing paper.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0040] See also Figures 1 to 7 The present invention provides a technical solution: a feeding mechanism with a double limit structure for a printing press, comprising a supporting foot 1, a supporting baffle 2 is welded on the top of the supporting foot 1, a transmission mechanism 3 is rotatably connected to the opposite side of the supporting baffle 2, a moving frame 4 is slidably connected to the front and rear outer walls of the supporting baffle 2, a clamping mechanism 5 is screwed on the opposite side of the moving frame 4, an adjusting mechanism 6 is rotatably connected to the top of the clamping mechanism 5, a transmission mechanism 7 is sleeved on the top of the adjusting mechanism 6, a supporting frame 8 is welded on one side of the top of the moving frame 4, a pressing mechanism 9 is vertically penetrated through the middle of the top of the supporting frame 8, and a rolling mechanism 10 is rotatably connected to the left and right inner walls of the moving frame 4;
[0041] The clamping mechanism 5 includes an electric telescopic rod 501, a first clamping plate 502, a second clamping plate 503 and a clamping pad 504, the tail end of the electric telescopic rod 501 is screwed to the lower end of the opposite side of the moving frame 4, the first clamping plate 502 is arranged at the driving end of the electric telescopic rod 501, the second clamping plate 503 is screwed to the outer wall of the adjusting mechanism 6, and the clamping pad 504 is arranged on the opposite side of the first clamping plate 502 and the second clamping plate 503; it should be noted that after the operator places the whole stack of printed paper horizontally on the top of the conveyor belt 303, the operator can first start the electric telescopic rods 501 on the left and right sides at the same time through the external controller, so that the driving end of the electric telescopic rod 501 begins to extend horizontally and pushes the first clamping plate 502 connected thereto toward the middle printed paper, until the clamping pad 504 arranged on the opposite side of the first clamping plate 502 is tightly attached to the left and right outer walls of the printed paper, and at the same time, when the adjusting mechanism 6 is started The second clamping plate 503 screwed thereto is moved up and down to perform a lifting operation, so as to complete the lateral clamping and limiting of the printing paper together with the first clamping plate 502 according to the actual height of the whole stack of printing paper. In actual use, through the precise control of the electric telescopic rod 501, the first clamping plate 502 can reliably fit the left and right outer walls of the printing paper to achieve precise lateral clamping, and the tight fit of the soft clamping pad 504 can reduce damage to the edge of the paper and protect the quality of the paper. During this period, the lifting and lowering operation of the second clamping plate 503 can be adjusted according to the actual thickness of the printing paper, so that the clamping mechanism 5 can adapt to papers of different thicknesses. The stable clamping provided by the clamping mechanism 5 can prevent the paper from moving or misaligning during transportation, ensure the stable transportation of the paper in the printing press, and at the same time reduce the accidental slipping or flying out of the paper during transportation, thereby improving the operational safety.
[0042] The pressing mechanism 9 includes a pressing plate 901, a pressing pad 902 and a hydraulic cylinder 903. The driving end of the hydraulic cylinder 903 vertically penetrates the middle of the top of the supporting frame 8. The driving end of the hydraulic cylinder 903 is provided with a pressing plate 901, and the bottom of the pressing plate 901 is provided with a pressing pad 902. It should be noted that after the operator completes the side clamping of the whole stack of printing paper through the clamping mechanism 5 and the adjusting mechanism 6, the hydraulic cylinder 903 can be started at this time, so that the driving end of the hydraulic cylinder 903 begins to extend downward and pushes the pressing plate 901 connected thereto to descend, until the pressing pad 902 arranged at the bottom of the pressing plate 901 can fit tightly against the top of the printing paper and exert a certain downward pressure on it, thereby completing the vertical clamping of the printing paper. The clamping limit in the vertical direction, and in actual use, the telescopic ability of the hydraulic cylinder 903 allows the pressing mechanism 9 to adapt to papers of different thicknesses, thereby improving the versatility and flexibility of the equipment, and the combination of the pressing plate 901 and the pressure pad 902 ensures the stable clamping of the printed paper in the vertical direction, reduces the movement of the paper during transportation, and the setting of the pressure pad 902 can prevent the pressing plate 901 from causing unnecessary damage to the paper and protect the integrity of the paper. At the same time, the stable downward force provided by the pressing mechanism 9 can also help maintain its position and direction during the paper transportation process, reduce operating errors, and the stable clamping helps to avoid misalignment or deformation of the paper during the printing process, thereby protecting the printing quality.
[0043] In this embodiment, Figure 3 and Figure 6 As shown, a first slide groove 201 is provided on the left and right outer walls of the support baffle 2, the movable frame 4 is slidably connected inside the first slide groove 201, a second slide groove 202 is provided on the top of the support baffle 2, a convex rail 203 is provided in the middle of the bottom wall of the second slide groove 202, and a compression spring member 204 is welded between the inner wall of one side of the first slide groove 201 and the movable frame 4.
[0044] The convex rail 203 and the second slide groove 202 form a concave track with a lower middle and higher sides. The first slide groove 201 is located directly below the second slide groove 202, and the positions of the central axes of the two coincide with each other. It should be noted that the operator can first place a stack of printed paper horizontally on the top of the conveyor belt 303, and then start the clamping mechanism 5 and the pressing mechanism 9 in sequence to limit the entire stack of printed paper in all directions. At the same time, the conveying mechanism 3 is started again to drive the printed paper placed on the top of the conveyor belt 303 to move horizontally. During this period, the moving frame 4 connected to the clamping mechanism 5 will slide horizontally along the inner wall of the first slide groove 201, and then the rolling mechanism 10 connected to the inner walls of the left and right sides of the moving frame 4 will also move horizontally along the outer wall of the convex rail 203 opened in the second slide groove 202, so that the printed paper can still be kept in the state of being limited and clamped by the clamping mechanism 5 and the pressing mechanism 9 during the transmission process. state, and in actual use, through the cooperation of the first slide groove 201 and the second slide groove 202, the movable frame 4 and the rolling mechanism 10 can achieve precise lateral movement, ensuring the precise positioning of the printed paper during the transmission process, and the precise mechanical movement can improve the efficiency of paper transportation, reduce paper jams and errors, and improve the overall production efficiency. The first slide groove 201 and the second slide groove 202 also provide a guiding function for the movable frame 4 and the rolling mechanism 10 to ensure that they move according to the predetermined path and ensure that the paper always remains on the correct path during the transmission process, thereby avoiding trajectory deviation and preventing the printed paper from being scattered. At the same time, through precise guiding and limiting, the impact and wear between mechanical parts can be reduced, and the equipment can be protected from damage. The synchronous movement of the movable frame 4 and the rolling mechanism 10 can ensure that the paper is always subject to limit control during the transmission process, thereby maintaining stable transportation.
[0045] When the operator starts the transmission mechanism 3 to drive the whole stack of printing paper to be transported horizontally, the movable frame 4 will also slide along the inner wall of the first slide groove 201, and during this period, the movable frame 4 will synchronously squeeze the compression spring member 204 arranged between it and the first slide groove 201 to compress and shorten it, so that the movable frame 4 can smoothly move horizontally in the first slide groove 201. After completing a printing paper transport operation, the operator can stop the transmission mechanism 3. At this time, the compression spring member 204 will push the movable frame 4 and other mechanisms connected to the movable frame 4 back to their original positions. In actual use, the compression spring member 204 can store energy and release it after the transmission mechanism 3 stops, helping the mobile frame 4 and related mechanisms to quickly return to the initial position, thereby utilizing the elastic force of the compression spring member 204 itself rather than a continuous power source to return the mechanism, reducing additional energy consumption, and the quick release feature of the compression spring member 204 can also speed up the resetting speed of the mechanism and improve production efficiency. At the same time, the use of the compression spring member 204 also simplifies the operating process of the mechanism, so that the mechanism can be reset without an additional reverse drive mechanism.
[0046] In this embodiment, Figure 5 As shown, the adjustment mechanism 6 includes a telescopic baffle 601, a rotating screw 602 and a motor 603. The telescopic baffle 601 is arranged between the first clamping plate 502 and the second clamping plate 503. The bottom end and the top end of the rotating screw 602 are respectively rotatably connected to the inside of the first clamping plate 502 and the second clamping plate 503. The top end of one of the rotating screws 602 is plugged with the motor 603, and the outer wall of the rotating screw 602 is screwed with the second clamping plate 503.
[0047] The length of the telescopic baffle 601 when stretched to its limit is the same as the length of the rotating screws 602 on the left and right sides, and the second clamping plate 503 forms a vertical movement structure with the rotating screws 602 through the threads provided on its inner wall; it should be noted that when the operator starts the electric telescopic rod 501 to push the first clamping plate 502 connected to it and the clamping pads 504 provided on its outer wall to fit tightly against the left and right outer walls of the printing paper, the operator can start the motor 603 at this time to make its output end start to rotate and drive the rotating screw 602 plugged therein to rotate together, and through the transmission mechanism 7 sleeved on the outer wall of its top end, the rotating screw 602 on the other side rotates synchronously, so that the second clamping plate 503 screwed to the outer walls of the two rotating screws 602 can move up and down along the thread direction until the second clamping plate 503 can reach the actual position of the printing paper. The second clamping plate 503 is moved to a certain height and stops, during which the telescopic baffle 601 arranged between the first clamping plate 502 and the second clamping plate 503 is also pulled to extend, thereby completing the side clamping and limiting of the whole stack of printing paper together with the first clamping plate 502 and the second clamping plate 503. In actual use, through the cooperation of the motor 603 and the rotating screw 602, the second clamping plate 503 can be driven to automatically adjust its vertical height, thereby adapting to printing papers of different thicknesses, thereby improving the adaptability and flexibility of the equipment, and the extension of the telescopic baffle 601 can keep synchronization with the first clamping plate 502 and the second clamping plate 503 and work in coordination, thereby ensuring the precise side clamping and limiting of the printing paper, which can improve the accuracy of paper positioning and increase the contact area between the clamping mechanism 5 and the printing paper, thereby enhancing the stability of the clamping mechanism 5 for the side clamping of the printing paper.
[0048] In this embodiment, Figure 5 As shown, the transmission mechanism 7 includes a transmission main wheel 701, a transmission slave wheel 702 and a belt 703. The transmission main wheel 701 is sleeved on the top outer wall of a rotating screw 602 to which a motor 603 is inserted, the transmission slave wheel 702 is sleeved on the top outer wall of another rotating screw 602, and the belt 703 is sleeved on the outer walls of the transmission main wheel 701 and the transmission slave wheel 702.
[0049] The wrap angle between the transmission main wheel 701, the transmission slave wheel 702 and the belt 703 is greater than 120°, and the rotating screws 602 on the left and right sides respectively form a rotating structure through the transmission main wheel 701 and the transmission slave wheel 702 at the corresponding positions; it should be noted that when the operator starts the motor 603 to drive the rotating screw 602 plugged therein to start rotating, the transmission main wheel 701 sleeved on the outer wall of the top end of this rotating screw 602 will also be driven to rotate together, and through the belt 703 sleeved on its outer wall, the transmission slave wheel 702 on the other side and the rotating screw 602 sleeved inside the transmission slave wheel 702 start to rotate at the same time, thereby realizing the rotation of the two rotating screws 602 Synchronously rotate, thereby driving the second clamping plate 503 screwed to the outer wall of the rotating screw 602 to rise and fall by itself. In actual use, the transmission mechanism 7 can ensure that the two rotating screws 602 rotate synchronously, so that the second clamping plate 503 can be lifted and lowered evenly and synchronously, maintaining the consistency of the clamping action, and ensuring the precise and stable operation of the clamping mechanism 5, while also improving the reliability of the equipment and the convenience of maintenance. By adjusting the speed of the motor 603, the speed of the transmission main wheel 701 and the transmission slave wheel 702 can be accurately controlled, so that the rotation speed of the two rotating screws 602 can be controlled at the same time, thereby realizing the precise regulation of the lifting speed and position of the second clamping plate 503.
[0050] In this embodiment, Figure 2 and Figure 4 As shown, the rolling mechanism 10 includes a rotating shaft 1001 and a roller 1002 , wherein the rotating shaft 1001 is rotatably connected to the left and right inner walls of the movable frame 4 , and the roller 1002 is sleeved on the outer wall of the rotating shaft 1001 , and the roller 1002 is rollingly connected to the outer wall of the convex rail 203 .
[0051] The concave part of the roller 1002 is just fitted into the convex part of the convex rail 203, and the roller 1002 and the convex rail 203 form a rolling structure, and the movable frame 4 is in a square frame shape as a whole; it should be noted that after the operator completes the all-round double limit of the whole stack of printing paper through the clamping mechanism 5 and the pressing mechanism 9, the operator can start the transmission mechanism 3 to drive the top of the conveyor belt 303 to start transmission. During this period, the movable frame 4 starts to slide along the first slide groove 201, and the rotating shaft 1001 connected to the inner wall on the left and right sides thereof will drive the roller 1002 to roll horizontally along the outer wall of the convex rail 203, thereby ensuring that the clamping mechanism 5 and the pressing mechanism 9 are in a state of being pressed against each other. The structure 9 can move along the conveying path of the printing paper. In actual use, the cooperation between the roller 1002 and the convex rail 203 ensures the smoothness of the printing paper when it moves horizontally, reduces the friction and potential damage of the paper during the conveying process, and the rolling mechanism 10 can dynamically follow the moving path of the printing paper, ensuring that the clamping mechanism 5 and the pressing mechanism 9 can still maintain a stable clamping of the printing paper during the paper conveying process. Compared with sliding friction, the rolling friction provided by the rolling mechanism 10 has lower energy consumption, and the rolling action of the roller 1002 reduces the resistance of the paper during the conveying process, thereby helping to reduce the energy consumption of the entire conveying process and at the same time improve the conveying efficiency.
[0052] In this embodiment, Figure 1 and Figure 7 As shown, the transmission mechanism 3 includes a transmission main shaft 301, a transmission slave shaft 302, a transmission belt 303 and a driving motor 304, the two ends of the transmission slave shaft 302 of the transmission main shaft 301 are rotatably connected to the opposite sides of the support baffle 2, the transmission belt 303 is sleeved on the outer wall of the transmission slave shaft 302 of the transmission main shaft 301, and the output end of the driving motor 304 is plugged into one end of the transmission main shaft 301.
[0053] The transmission belt 303 is composed of a traveling structure through a transmission main shaft 301 and a transmission slave shaft 302, and the transmission main shaft 301 is composed of a rotating structure through a driving motor 304. It should be noted that after the operator places the whole stack of printing paper horizontally on the top of the transmission belt 303, the clamping mechanism 5 and the pressing mechanism 9 can be started first to double-limit the whole stack of printing paper, and then the driving motor 304 is started to make its output end start to rotate and drive the transmission main shaft 301 plugged therein to vibrate together, and drive the transmission slave shaft 302 on the other side to rotate synchronously through the transmission belt 303 sleeved on its outer wall, so that the transmission belt 303 can be wound along the outer wall of the shaft body and then connected. The printing paper placed on top of it can be transported toward the processing mechanism. In actual use, the transmission mechanism 3 can efficiently move the printing paper from one position to another, thereby improving the overall production efficiency. At the same time, the design of the transmission mechanism 3 can also realize the continuous transportation of printing paper, ensuring the smooth progress of the production process, and through the precise control of the drive motor 304, the rotation speed of the transmission main shaft 301 and the transmission slave shaft 302 can be precisely controlled, thereby realizing precise control of the transmission speed and position to meet the requirements of printing accuracy. The use of the transmission belt 303 ensures the stability of the printing paper during transportation and reduces the risk of paper damage.
[0054] The method of using the present invention: The printing machine uses a feeding mechanism with a double limit structure. When in use, the working process is as follows:
[0055] like Figures 1 to 7As shown, the operator can first place a stack of printing paper horizontally on the top of the conveyor belt 303, and then start the electric telescopic rods 501 on the left and right sides at the same time through the external controller, so that the driving end begins to extend horizontally and pushes the first clamping plate 502 connected thereto toward the printing paper in the middle, until the clamping pads 504 arranged on the opposite side of the first clamping plate 502 are tightly attached to the left and right outer walls of the printing paper. At the same time, the electric telescopic rod 501 is started to push the first clamping plate 502 connected thereto and the clamping pads 504 arranged on the outer wall thereof to tightly fit the left and right outer walls of the printing paper. At this time, the operator The personnel can start the motor 603, so that its output end starts to rotate and drives the rotating screw 602 plugged therein to rotate together, and the rotating screw 602 on the other side is rotated synchronously through the transmission mechanism 7 sleeved on the outer wall of the top end thereof, so that the second clamping plate 503 screwed to the outer wall of the two rotating screws 602 can move up and down along the thread direction until the second clamping plate 503 can reach the actual height of the printing paper and stop. During this period, the telescopic baffle 601 arranged between the first clamping plate 502 and the second clamping plate 503 will also be pulled to extend, so as to be connected with the first clamping plate 502 and the second clamping plate 503 completes the side clamping and limiting of the whole stack of printing paper. At this time, the hydraulic cylinder 903 can be started to make its driving end begin to extend downward and push the pressure plate 901 connected thereto to descend until the pressure pad 902 arranged at the bottom of the pressure plate 901 can be closely fitted to the top of the printing paper and exert a certain downward pressure thereon, thereby completing the clamping and limiting of the printing paper in the vertical direction. After completing the double limiting of the whole stack of printing paper, the driving motor 304 can be started to drive the transmission main shaft 301 plugged therewith to vibrate together, and drive the transmission belt 303 on the outer wall thereof to drive the transmission on the other side. The slave shaft 302 rotates synchronously, so that the conveyor belt 303 can be wound and advanced along the outer wall of the shaft, and then the printed paper placed on the top of it can be transported toward the processing mechanism. During this period, the movable frame 4 connected to the clamping mechanism 5 will slide laterally along the inner wall of the first slide groove 201, and then the rolling mechanism 10 connected to the inner walls on the left and right sides of the movable frame 4 will also move synchronously laterally along the outer wall of the convex rail 203 opened inside the second slide groove 202, so that the printed paper can still remain in a state of being limited and clamped by the clamping mechanism 5 and the pressing mechanism 9 during the transmission process.
