Technical Field
[0001] This utility model relates to the field of punching device technology, and in particular to a punching device for printing and packaging. Background Technology
[0002] Printed packaging refers to printing on various packaging materials to add decorative patterns, designs, or text, making products more attractive or informative, thereby conveying information and increasing sales. This includes printing on cartons, bottles, cans, etc. Printed packaging constitutes a significant portion of both the printing and packaging industries and is an indispensable part of packaging engineering. Printing methods include letterpress printing, offset printing, gravure printing, screen printing, and perforated printing. The main elements of printing include paper, ink, and color. Printed packaging must consider economic efficiency and environmental protection, while simultaneously conveying the printed information completely and effectively. Furthermore, the printed packaging often requires perforation for ease of use.
[0003] For example, the patent entitled "A Packaging Material Punching Machine for Easy Installation" (patent publication number: CN216682540U) discloses a packaging material punching machine that is easy to install. By setting up structures such as hole openers and moving blocks, it can be installed and disassembled at any time without the need for professional tools during the installation process. The overall structure is relatively simple and easy to maintain. However, it cannot compress the packaging material during punching, which makes the packaging material prone to shaking and tilting, resulting in low punching efficiency.
[0004] Therefore, it is necessary to propose a punching device for printing and packaging to solve the above problems. Utility Model Content

U-shaped frame; 22. Motor. Detailed Implementation
[0022] This utility model provides, for example Figures 1-4 The punching device for printing and packaging shown includes an operating table 1, a U-shaped frame 21 above the operating table 1, and support columns 18 fixedly connected to both ends of the top of the operating table 1. A horizontal plate 19 is provided above the operating table 1 and is fixedly connected between the tops of the two support columns 18. A sliding plate 2 is slidably arranged between the two support columns 18. An electric push rod 20 is fixedly connected to the horizontal plate 19, and the sliding plate 2 is fixedly connected to the telescopic end of the electric push rod 20.
[0023] The U-shaped frame 21 is fixedly connected to the slide plate 2. A drill bit 3 is rotatably installed at the bottom of the U-shaped frame 21. A motor 22 is fixedly connected inside the U-shaped frame 21. The drill bit 3 is fixedly connected to the drive shaft of the motor 22.
[0024] Specifically, the electric push rod 20 drives the slide plate 2 to move up and down between the two pillars 18, and the motor 22 drives the drill bit 3 to rotate, thus realizing the drilling operation.
[0025] Considering that the drill bit 3 directly contacts the packaging material during drilling, it cannot compress the packaging material and is prone to shaking and deflection, which makes the drilling inaccurate. A fixed box 4 is fixedly connected to the bottom of the U-shaped frame 21. The fixed box 4 surrounds the outside of the drill bit 3, and a sliding box 5 is slidably provided on the outside of the fixed box 4.
[0026] Specifically, the sliding box 5 abuts against the packaging material, pressing the packaging material firmly to prevent it from shaking or tilting, thus improving the accuracy of drilling. Furthermore, during the drilling process, the sliding box 5 will adaptively slide upward on the fixed box 4, always maintaining a pressed state.
[0027] Slide grooves 6 are provided on both outer walls of the fixed box 4. A slider 7 is slidably installed inside the slide groove 6. The slider 7 is fixedly connected to the inner wall of the slide box 5. The slide grooves 6 and slider 7 are provided to improve the sliding stability of the slide box 5.
[0028] The slide 6 is equipped with a buffer assembly, which includes a first magnet 8 and a second magnet 9. The first magnet 8 is fixedly connected to the top of the slide 6, and the second magnet 9 is fixedly connected to the slider 7. The first magnet 8 and the second magnet 9 are engaged in a repulsive manner. The buffer assembly can also be replaced with a spring, which can be adjusted according to the specific application.
[0029] When the sliding box 5 slides upward adaptively on the fixed box 4, the repulsive force between the first magnet 8 and the second magnet 9 ensures that the sliding box 5 slides upward stably; after drilling is completed, the drill bit 3 moves upward, and under the action of the repulsive force between the first magnet 8 and the second magnet 9, the sliding box 5 slides downward to reset.
[0030] Considering that a lot of debris will be generated during the drilling process, an air supply chamber 10 is provided on one side of the slide box 5 to clean up the debris. An air jet groove 11 is provided on the inner wall of the slide box 5 and is connected to the air supply chamber 10. A suction chamber 13 is provided on the other side of the slide box 5 and a suction groove 14 for suctioning debris is provided on the inner wall of the slide box 5 and is connected to the suction chamber 13.
[0031] An air supply pipe 15 is fixedly connected to the sliding box 5. The air supply pipe 15 is connected to the air supply chamber 10. The end of the air supply pipe 15 away from the sliding box 5 is connected to the cooling gas delivery pipeline of the factory. Cooling gas is delivered into the air supply chamber 10 through the air supply pipe 15. A suction pipe 17 is fixedly connected to the sliding box 5. The suction pipe 17 is connected to the suction chamber 13. The suction pipe 17 is connected to the gas suction pipeline of the factory. The debris is sucked out by the suction groove 14 and the suction chamber 13 and transported to the factory's centralized air treatment pipeline for processing.
[0032] In addition, a gas circulation system, including a pump body, filter screen, and semiconductor cooling chip, can be installed between the air supply pipe 15 and the suction pipe 17 to achieve gas circulation, which can be adjusted according to the specific usage.
[0033] When the cooling gas is delivered to the air supply chamber 10, it will be sprayed towards the drilling position by the jet vent 11 to blow away the debris and cool down the drill bit 3; at the same time, the blown-away debris will be sucked away by the suction vent 14 and the suction chamber 13.
[0034] An airbag 12 and a solenoid valve 16 are installed on the air supply duct 15. The solenoid valve 16 and other structures are connected to the factory's power supply, and the airbag 12 can be suspended on the slide plate 2 by a rope so that it does not come into contact with the packaging material.
[0035] During operation, when cooling gas is supplied to the air supply chamber 10 through the air supply pipe 15, the solenoid valve 16 is closed. Since the solenoid valve 16 is in the closed state, the cooling gas accumulates inside the air bag 12, causing the air bag 12 to expand. Then the solenoid valve 16 is opened, and with the assistance of the air bag 12's own reset elasticity, the cooling gas is sprayed at high speed from the jet groove 11 to the drilling position, blowing away debris and cooling the drill bit 3. At the same time, the blown-away debris is sucked away by the suction groove 14 and the suction chamber 13, and the debris is filtered inside the filter box 17.
[0036] The above steps are repeated multiple times, intermittently increasing the ejection speed of the cooling gas to improve the effect of debris removal and drill bit cooling.
[0037] Alternatively, solenoid valve 16 can be opened to maintain the normal delivery speed of cooling gas, which can be adjusted according to specific usage conditions.
[0038] Specifically, a pressure sensor can be installed inside the airbag 12, and a controller can be installed to connect between the solenoid valve 16 and the pressure sensor. When the pressure sensor detects that the pressure inside the airbag 12 exceeds a set threshold, this information is transmitted to the controller, which then controls the solenoid valve 16 to open. The controller and its control principle are common existing technologies and will not be elaborated here.
[0039] By setting up structures such as the fixed box 4, the sliding box 5, and the airbag 12, the packaging material is pressed tightly to prevent it from shaking or tilting, thereby improving the accuracy of punching. At the same time, debris is blown away and sucked up for cleaning, and the spray speed of cooling gas is intermittently increased to improve punching efficiency.
