Description

Technical Field

[0001] The invention relates to the technical field of die-cutting machines, and in particular to a fully automatic waste-clearing flat-bed die-cutting machine and a use method thereof. Background Art

[0002] An automatic die-cutting machine is a machine that uses die-cutting knives, steel knives, hardware molds, etc. to apply a certain amount of pressure through a stamping plate to cut printed products or cardboard into specific shapes. It consists of a non-stop high-speed paper feeding mechanism, a die-cutting mechanism, a waste removal mechanism, a finished product removal mechanism, a waste edge conveying mechanism, a paper collection mechanism, and an electrical unit. During the production process, the raw materials are fed into the die-cutting mechanism through a non-stop high-speed paper feeding mechanism. The die-cutting mechanism uses a die-cutting knife for cutting, and at the same time uses the flipping mechanism in the die-cutting mechanism to flip the product to ensure double-sided processing. The product then enters the waste removal mechanism to remove unnecessary waste scraps. Next, the product enters the finished product removal mechanism for cleaning and sorting to ensure that the product meets the standards. Waste edges and waste materials will be processed and cleaned by the waste edge conveying mechanism. Finally, the die-cut and waste-removed products are collected and stacked by the paper collection mechanism. At the same time, the electrical unit is responsible for controlling the operation of the entire machine and monitoring the working status of each part.

[0003] An automatic cardboard turning device disclosed in the patent application with reference publication number CN217263527U, wherein the turning frame thereon rotates around its center line during the rotation process, thereby reducing the space occupied during the rotation process, thereby facilitating the reduction of the volume of the device and saving space resources, and the electric slide can drive the rack to move, and the rack can mesh with the gear in turn during the movement process to drive the gear to rotate, and the gear can drive the roller to rotate, and the roller conveys the cardboard out of the turning mechanism, and when the rack is disengaged from the gear, the cardboard is also disengaged from the corresponding roller, so that the roller that is not in contact with the cardboard does not need to rotate, thereby reducing the friction of the roller and extending its service life.

[0004] Comprehensive analysis of the above reference patents shows the following defects:

In addition, the structure for clamping the cardboard cannot flexibly adjust the spacing and can only clamp cardboard of a specific length, and has poor adaptability. Therefore, it is necessary to provide a fully automatic waste stripping flat die-cutting machine and its use method to solve the above technical problems. Summary of the invention

[0019] Step 1: The cardboard is transported to the turning mechanism through the paper feeding mechanism and is located in the turning frame assembly. The die-cutting mechanism performs die-cutting on one side of the cardboard according to a predetermined shape and size. After the side of the cardboard is die-cut, the electric telescopic rod is first started to drive the bearing base plate assembly to rotate, so that the front end of the bearing base plate assembly rotates to the bottom, and rotates from the initial horizontal state to the vertical state. Then the servo motor is started to drive the screw rod to rotate. Under the limiting action of the U-shaped limiting track, the turning frame assembly moves in the up and down direction. During the process, the turning frame assembly is first moved downward. After moving downward for a certain distance, the turning frame assembly meshes with the teeth, so that the turning frame assembly moves downward and turns over until it turns over 180 degrees, that is, the cardboard clamped by the turning frame assembly is turned over 180 degrees;

[0021] Step 3, then start the electric telescopic rod again to push the bearing bottom plate assembly to the initial horizontal state. At this time, the top of the bearing bottom plate assembly contacts the bottom of the cardboard, and then start the die-cutting mechanism to die-cut the other side of the cardboard according to the predetermined shape and size for double-sided processing. After automatic die-cutting, the cardboard is pushed to the left by the paper feeding mechanism and enters the waste cleaning mechanism to remove unnecessary waste scraps. Next, it enters the finished product cleaning mechanism for cleaning and sorting. The waste edges and waste materials are cleaned and transported away by the waste edge conveying mechanism. Finally, the die-cut and waste-cleaned cardboard is collected and stacked by the paper collection mechanism.

[0052] The embodiment of the present invention also provides a method for using a fully automatic waste stripping flat die-cutting machine, using the fully automatic waste stripping flat die-cutting machine, and the specific method includes the following steps:

[0053] Step 1: The cardboard is conveyed to the flip mechanism 3 through the paper feeding mechanism 1 until it is completely pushed between the two L-shaped frames 3592. Then, the die-cutting mechanism 2 die-cuts the upward side of the cardboard according to the predetermined shape and size. After the side of the cardboard is die-cut, the electric telescopic rod 37 is first started to drive the bearing bottom plate assembly 36 to rotate, so that the front end of the bearing bottom plate assembly 36 rotates to the lower part, and rotates from the initial horizontal state to the vertical state. Then, the servo motor is started to drive the screw rod 34 to rotate, and the U-shaped limit track 33 is limited. The turning frame assembly 35 is moved in the up-down direction. During the process, the turning frame assembly 35 is first moved downward. After a certain distance downward, the gear 357 meshes with the teeth 39, so that the gear 357 moves downward and turns over at the same time. The rotating shaft 356, the square rod 355, the shaft rod 358 and the two clamping frame assemblies 359 turn over accordingly. When the gear 357 is separated from the teeth 39, the gear 357 and the clamping frame assembly 359 turn over 180 degrees, that is, the cardboard clamped between the four L-shaped frames 3592 is turned over 180 degrees.

[0054] Step 2, the flip frame assembly 35 continues to move downward. Under the limiting action of the second guide groove 312, the protruding rod 3543 is pushed forward at the same time, and the gear 357 moves forward accordingly. During the process, the protruding block 3545 is acted upon by the driving block 3531 and is pushed downward and completely enters the accommodating cavity 3544 until the protruding rod 3543 is pushed to the bottom of the second guide groove 312. At this time, the flip frame assembly 35 no longer moves downward, and the protruding block 3545 penetrates into another positioning hole 3535 under the elastic action of the spring 3546. At this time, the gear 357 is located in front of the protruding strip 38. Then the servo motor drives the lead screw 34 to reverse, driving the flip frame assembly 35 to move upward. During the upward movement of the flip frame assembly 35, the gear 357 does not mesh with the tooth 39 , the cardboard clamped between the four L-shaped frames 3592 maintains the same flip angle, and the flip frame assembly 35 continues to move up. Under the limiting action of the first guide groove 311, the protruding rod 3543 is pushed backward at the same time, and the gear 357 moves backward accordingly. During the process, the protruding block 3545 is pushed downward by the driving block 3531 and fully enters the accommodating cavity 3544 again until the protruding rod 3543 is pushed to the top of the first guide groove 311. At this time, the flip frame assembly 35 no longer moves up, and the protruding block 3545 is re-entered into the original positioning hole 3535 under the elastic action of the spring 3546. At this time, the gear 357 and the protruding strip 38 are located on the same vertical section, and the cardboard is also pushed to the original horizontal height, with the other side of the cardboard facing upward;

[0055] Step 3, then start the electric telescopic rod 37 again, push the bearing bottom plate assembly 36 to the initial horizontal state, make the top of the bearing bottom plate assembly 36 contact with the bottom of the cardboard, and then start the die-cutting mechanism 2 to die-cut the other side of the cardboard according to the predetermined shape and size, and perform double-sided processing. After the automatic die-cutting, the cardboard is pushed to the left by the paper feeding mechanism 1, separated from between the two L-shaped frames 3592, and enters the waste removal mechanism 4 to remove unnecessary waste scraps, and then enters the finished product removal mechanism 5 for cleaning and sorting to ensure that the processed cardboard meets the standards. The waste edges and waste materials are cleaned and transported away by the waste edge conveying mechanism 6. Finally, the die-cut and waste-cleaned cardboard is collected and stacked by the paper collection mechanism 7. At the same time, the electrical unit is responsible for controlling the operation of the entire machine and monitoring the working status of each part. Among them, the paper feeding mechanism 1, the die-cutting The mechanism 2, the waste clearing mechanism 4, the finished product clearing mechanism 5, the waste edge conveying mechanism 6 and the paper collecting mechanism 7 belong to the prior art known to those skilled in the art. When the length of the cardboard to be die-cut and the part to be die-cut change, open the sealed door at the rear of the die-cutting mechanism 2, and adjust the total number of supporting panels 366 and the position of the supporting panels 366 on the frame 361. During the process, when it is necessary to increase the number of supporting panels 366, just pass the new supporting panels 366 through the through opening 315 and the notch 363 into the frame 361, and slide them between the two placement grooves 362. After increasing the required number, observe the scale 365 and accurately adjust the position of each supporting panel 366. After adjusting to the specified position, use the second bolt 367 to position the supporting panel 366 to ensure that the cardboard is fully supported during the die-cutting process.

2. A method for using a fully automatic waste stripping flat die-cutting machine, characterized in that: Using the fully automatic waste stripping flat die-cutting machine as claimed in claim 1, the method comprises the following steps: Step 1: The paperboard is conveyed to the turning mechanism (3) through the paper feeding mechanism (1) and is located in the turning frame assembly (35). The die-cutting mechanism (2) performs die-cutting on one side of the paperboard according to a predetermined shape and size. After the side of the paperboard is die-cut, the electric telescopic rod (37) is first started to drive the bearing base plate assembly (36) to rotate, so that the front end of the bearing base plate assembly (36) rotates to the bottom and rotates from an initial horizontal state to a vertical state. Then, the servo motor is started to drive the screw rod (34) to rotate. Under the limiting action of the U-shaped limiting track (33), the turning frame assembly (35) moves in the up and down direction. During the process, the turning frame assembly (35) is first moved downward. After moving downward for a certain distance, the turning frame assembly (35) meshes with the teeth (39), so that the turning frame assembly (35) moves downward and flips at the same time until it flips 180 degrees, that is, the paperboard clamped by the turning frame assembly (35) is flipped 180 degrees. Step 2: The flip frame assembly (35) continues to move downward. Under the limiting action of the second guide groove (312), the connecting frame assembly (354) moves forward, and the square rod (355), the rotating shaft (356) and the gear (357) move forward accordingly. Then, the servo motor drives the lead screw (34) to reverse, driving the flip frame assembly (35) to move upward. During the process of the flip frame assembly (35) moving upward, it does not mesh with the teeth (39) until the paperboard is pushed to the original horizontal height, at which time the other side of the paperboard faces upward. Step 3: Then the electric telescopic rod (37) is started again to push the bearing bottom plate assembly (36) to the initial horizontal state. At this time, the top of the bearing bottom plate assembly (36) contacts the bottom of the cardboard. Then the die-cutting mechanism (2) is started to die-cut the other side of the cardboard according to the predetermined shape and size to perform double-sided processing. After the automatic die-cutting is completed, the cardboard is pushed to the left by the paper feeding mechanism (1) and enters the waste cleaning mechanism (4) to remove unnecessary waste scraps. Then, it enters the finished product cleaning mechanism (5) for cleaning and sorting. The waste scraps and waste materials are cleaned and transported away by the waste conveying mechanism (6). Finally, the die-cut and waste-cleaned cardboard is collected and stacked by the paper receiving mechanism (7).
