Description

Technical Field

[0001] This utility model relates to a die-cutting machine, specifically to an adjustable non-stop paper feeding mechanism for a die-cutting machine. Background Technology

[0002] A die-cutting machine is a device specifically designed for post-printing paper processing. One type of die-cutting machine operates by using grippers to feed individual sheets of paper to the die-cutting unit for die-cutting. This type of die-cutting machine requires a paper feeding mechanism to supply paper. Traditional paper feeding mechanisms use a single lifting platform structure. By placing a tray with stacked paper on the lifting platform, the paper is fed by controlling the lifting platform to rise. The drawbacks of this paper feeding mechanism are: after the tray is fed onto the lifting platform, only the lifting platform can be controlled to move the tray up and down, but there may be some error in the left and right position of the tray and the paper stack, resulting in a certain positional offset in subsequent paper feeding and affecting die-cutting accuracy; in addition, after the paper on the lifting platform is removed, this type of paper feeding mechanism requires setting a stop to wait for the lifting platform to descend and replenish the paper, which cannot achieve non-stop operation, resulting in poor smoothness and efficiency of the equipment operation. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide an adjustable non-stop paper feeding mechanism for a die-cutting machine to solve the above problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] An adjustable non-stop paper feeding mechanism for a die-cutting machine includes a lifting platform connected to a first lifting drive assembly. A movable frame is provided on one side above the lifting platform and connected to a movable drive assembly. The movable frame is mounted on the lifting platform and connected to a second lifting drive assembly. A movable tray is provided on the lifting platform and connected to a first movable adjustment assembly. A first sensor on the frame is used to sense the left and right position of the paper on the tray. The first sensor controls the movement of the first adjustment assembly. An adjustment frame is movably mounted on the movable frame. Paper-holding rods are spaced apart on the adjustment frame and can be inserted into slots on the tray. A second movable adjustment assembly on the movable frame drives the adjustment frame to move left and right. A second sensor on the frame is used to sense the left and right position of the tray on the tray. The second sensor controls the movement of the second movable adjustment assembly. A paper-stopping strip is provided on one side corresponding to the paper-holding rod.

[0006] The first lifting drive assembly includes a first chain that passes around a first sprocket, the first sprocket being connected to the output end of a first motor, and the first chain being connected to a lifting platform. The second lifting drive assembly includes a second chain that passes around a second sprocket, the second sprocket being connected to the output end of a second motor, and the second chain being connected to a lifting frame.

[0007] The mobile drive assembly includes a third chain that passes around a third sprocket, the third sprocket being connected to the output end of a third motor, and the third chain being connected to the mobile frame.

[0008] The first moving adjustment component includes a first push rod linear motor. The push rod of the first push rod linear motor is hinged to one end of the first transmission arm. The other end of the first transmission arm is connected to a first slider movably disposed on the lifting platform. The first slider is provided with a roller, which is engaged in an inclined groove on the support plate. A guide component is provided corresponding to the support plate.

[0009] The second moving adjustment assembly includes a second push rod linear motor. The push rod of the second push rod linear motor is hinged to one end of the second transmission arm, and the other end of the second transmission arm is hinged to the moving seat. The moving seat can press the paper-holding rod to move.

[0010] The movable seat is provided with roller sets, each roller set having two guide rollers, which clamp the paper support rod on both sides.

[0011] The adjustable non-stop paper feeding mechanism of the die-cutting machine described above uses a pallet mounted on a lifting platform. A first sensor detects the position of the paper stack on the pallet and controls a first movable adjustment component to move the pallet and the pallet left and right, adjusting the left and right position of the paper to ensure the accuracy of subsequent paper feeding. Simultaneously, a paper-supporting rod is configured to switch the lifting supply after the paper stack rises to a certain height, allowing the lifting platform to descend to replenish the paper stack and achieve continuous paper supply. A second sensor detects the left and right position of the pallet and controls a second movable adjustment component to adjust the left and right position of the paper-supporting rod, ensuring that the rod accurately inserts into the slot on the pallet where the left and right positions are adjusted, guaranteeing the transfer and lifting supply of the paper stack.

[0017] As shown in the figure, the adjustable non-stop paper feeding mechanism of the die-cutting machine disclosed in this utility model includes a lifting platform 2, which is connected to a first lifting drive assembly. A movable frame 11 is provided on one side above the lifting platform 2, and the movable frame 11 is connected to a movable drive assembly. The movable frame 11 is mounted on a lifting frame 5, which is connected to a second lifting drive assembly. A movable tray 1 is provided on the lifting platform 2, and the tray 1 is connected to a first movable adjustment assembly. A first sensor is provided on the frame to sense the left and right positions of the paper on the tray 1. The first sensor can control the movement of the first adjustment assembly. An adjustment frame 12 is movably mounted on the movable frame 11. Paper-holding rods 13 are spaced apart on the adjustment frame 12 and can be inserted into slots on the tray 3. A second movable adjustment assembly is provided on the movable frame 11 to drive the adjustment frame 12 to move left and right. A second sensor is provided on the frame to sense the left and right positions of the tray 3 on the tray 1. The second sensor can control the movement of the second movable adjustment assembly. In this embodiment, the first and second sensors can be photoelectric sensors. A paper stop strip 17 is provided on one side of the paper holder 13.

[0018] Furthermore, the first lifting drive assembly includes a first chain that passes around a first sprocket, the first sprocket being connected to the output end of the first motor, and the first chain being connected to the lifting platform 2. The second lifting drive assembly includes a second chain that passes around a second sprocket, the second sprocket being connected to the output end of the second motor, and the second chain being connected to the lifting frame 5. Using the above technical solution, by controlling the operation of the first and second motors and through sprocket and chain transmission, the lifting platform 2 and the lifting frame 5 can be driven to perform lifting movements.

[0019] Furthermore, the motion drive assembly includes a third chain that bypasses a third sprocket. The third sprocket is connected to the output end of a third motor, and the third chain is connected to the moving frame 11. With this structure, by controlling the start of the third motor and driving it through the chain and sprocket, the moving frame 11 can be moved back and forth.

[0020] Furthermore, the first moving adjustment component includes a first push rod linear motor 6. The push rod of the first push rod linear motor 6 is hinged to one end of the first transmission arm 7, and the other end of the first transmission arm 7 is connected to a first slider 8 movably mounted on the lifting platform 2. The first slider 8 is equipped with a roller 10, which is engaged in an inclined groove 9 on the tray 1. A guide component is provided corresponding to the tray 1. The guide component can be a pulley connected to the bottom of the tray 1, which is movably mounted in a guide groove on the lifting platform 2. Using the above technical solution, by controlling the action of the first push rod linear motor 6 and transmitting it through the first transmission arm 7, the first slider 8 and the roller 10 can be moved. When the roller 10 moves, it will transmit the inclined groove 9, thereby moving the tray 1 under the guidance of the guide component, and thus driving the tray 1 and the pallet 3 to adjust in the left and right directions, so that the left and right positions of the paper can be adjusted to the correct position, ensuring the accuracy of the left and right positions during the subsequent paper conveying process.

[0021] Furthermore, the second moving adjustment assembly includes a second push rod linear motor 14. The push rod of the second push rod linear motor 14 is hinged to one end of the second transmission arm, and the other end of the second transmission arm is hinged to the moving seat 15. The moving seat 15 can press the paper-supporting insert 13 to move. In addition, a roller group is arranged on the moving seat 15, and each roller group has two guide rollers 16. The two guide rollers 16 clamp the two sides of the paper-supporting insert 13. Using the above technical solution, by controlling the second push rod linear motor 14, the moving seat 15 can be moved, which in turn drives the paper-supporting insert 13 to move left and right, so that the paper-supporting insert 13 can be aligned with the slot on the tray 3 after adjustment, ensuring that the insert can be accurately inserted into the slot on the tray 3 to support the paper stack and continue to drive the paper stack to rise to achieve the paper feeding operation.

[0022] The working principle of this utility model is as follows: A tray 3 stacked with paper is fed onto a pallet 1. At this time, the first sensor senses the left and right position of the paper stack on the tray 3 and feeds back information to the controller. If the controller analyzes that the left and right position of the paper stack has shifted, it will control the first moving adjustment component to move the pallet 1 left and right until the left and right position of the paper stack is adjusted to the correct position. Then, the lifting platform 2 moves the pallet 1 and the tray 3 gradually upward to achieve paper supply. The second sensor senses the tray 3 after the left and right position is adjusted and feeds back information to the controller. At this time, the controller will control the second moving adjustment component to move the paper-holding rod 13 left and right so that the paper-holding rod 13 can engage with the slot on the tray 3. Once aligned, when tray 3 rises to the set position, the moving frame 11 will drive the paper-supporting rod 13 to insert into the slot on tray 3, supporting the paper stack, and control the lifting frame 5 to rise to achieve paper supply. At this time, the lifting platform 2 can drive the empty tray 3 to descend, replacing the tray with the paper stack with the empty tray. Then, control the lifting platform 2 to rise again. When the paper stack on tray 3 on the lifting platform 2 is about to connect with the paper stack on the paper-supporting rod 13, control the moving frame 11 to drive the paper-supporting rod 13 to retract, and the lifting frame descends to drive the paper-supporting rod 13 to reset. The paper stack on the paper-supporting rod 13 is blocked by the paper-stopping strip 17, so that it separates from the paper-supporting rod 13 and falls naturally to the top of the paper stack on tray 3 to complete the connection of the paper stack.
