Abstract
Description
Technical Field
[0001] This utility model relates to the field of cardboard box production technology, specifically a punching device for producing folding cardboard boxes. Background Technology
[0002] Folding cartons are among the most widely used packaging products. Their structure is typically made by folding corrugated cardboard. Depending on the flute type and number of layers, they can be further divided into various specifications and models. To facilitate handling and retrieval of items from folding cartons, through-holes are usually provided on the sides of the carton. These through-holes are generally created by punching holes after the carton is formed.
[0003] In the existing technology, in order to make the overall appearance of the carton, it is generally necessary to punch multiple holes at equal intervals. When multiple holes need to be punched at equal intervals, traditional punching devices can only punch one hole at a time on the cardboard, and the position of the cardboard needs to be manually adjusted. This not only affects the punching accuracy, but also makes it more time-consuming and labor-intensive. Multiple manual adjustments can also damage the carton and waste the cardboard, which not only increases the processing cost, but also greatly reduces the production efficiency. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] Example 1: Please refer to Figures 1-4This utility model provides a technical solution: a punching device for folding carton production, comprising: a fixed frame 1, which stably supports a large air cylinder 2, the large air cylinder 2 being electrically connected to an external terminal control device; the large air cylinder 2 being fixedly installed on the top of the fixed frame 1; a punching assembly being provided at the bottom output end of the large air cylinder 2; the punching assembly including a support frame 3; a threaded rod 4 being rotatably installed on one side of the support frame 3, the support frame 3 indirectly supporting the threaded rod 4; a movable sleeve 5 being threadedly sleeved on the threaded rod 4, thereby facilitating the movement of the movable sleeve 5; and a drive plate 6 being slidably installed on the other side of the support frame 3; one side of the drive plate 6 being fixedly connected to the movable sleeve 5; and the other side of the drive plate 6 being... A driven plate 7 is provided on one side, and a fixed plate 8 is provided on one side of the driven plate 7. The driven plate 7 is slidably connected to the support frame 3, and the fixed plate 8 is fixedly connected to the support frame 3. The drive plate 6, the driven plate 7, and the fixed plate 8 are rotatably connected through the cooperation of the long plate 9 and the short plate 10. A small motor 11 is fixedly installed at the bottom of the drive plate 6, the driven plate 7, and the fixed plate 8. A drilling bit 12 is fixedly connected to the output end of the small motor 11. The drilling bit 12 is driven to rotate by the small motor 11 to make holes. A placement plate 13 is provided on the lower side of the drilling bit 12. Clamping components are provided on both sides of the upper surface of the placement plate 13. The clamping components are designed to facilitate the clamping of the cardboard.
[0027] The operator places the cardboard on the placement plate 13, then clamps it using the clamping assembly to secure it. The spacing between the multiple holes is determined, and then the threaded rod 4 is rotated. The threaded rod 4 drives the threaded sleeve 5, which in turn moves the moving sleeve 5. The moving sleeve 5 then drives the drive plate 6 to slide along the axis of the threaded rod 4 on one side of the support frame 3. The drive plate 6, through its rotational connection with the short plate 10, drives the long plate 9 to rotate. The long plate 9, through its rotational connection with the driven plate 7, drives the driven plate 7 to move synchronously. The fixed plate 8 remains stationary. Then, by adjusting the rotation direction of the threaded rod 4, the drive plate 6 and the driven plate 7 can be controlled to move closer to or further away from the fixed plate 8, thereby adjusting the distance between them, and thus adjusting the distance between the holes. After adjusting to the appropriate position, the small motor 11 and the large cylinder 2 are started. The output shaft of the small motor 11 drives the drilling bit 12 to rotate at high speed, while the large cylinder 2 drives the support frame 3 to move downward, so that the drilling bit 12 gradually contacts the cardboard, ultimately realizing the simultaneous drilling of multiple holes in the cardboard. The distance between the holes can be adjusted, expanding the range of applications and improving the practicality of the entire device.
[0028] Example 2: Based on Example 1, the top of the large air cylinder 2 is fixedly connected to the top of the fixed frame 1, the bottom output end of the large air cylinder 2 is fixedly connected to the upper surface of the support frame 3, the bottom two sides of the fixed frame 1 are fixedly connected to the upper surface of the placement plate 13, and a drive assembly is provided on the side of the support frame 3 near the threaded rod 4. The drive assembly includes a large motor, which is fixedly installed on one side surface of the support frame 3. The output end of the large motor is fixedly fitted with an active meshing wheel, and one end of the threaded rod 4 is fixedly fitted with a driven meshing wheel. The active meshing wheel and the driven meshing wheel are meshed and transmitted through a meshing belt, thereby avoiding slippage during the transmission process, improving the transmission accuracy, and also improving the transmission accuracy of the threaded rod 4.
[0029] The threaded rod 4 is rotatably sleeved on both sides within the support seat 14, which provides stable support for the threaded rod 4. The support seat 14 is fixedly installed on one side of the support frame 3. The movable sleeve 5 is fixedly connected to the drive plate 6 via the connecting plate 15. The connecting plate 15 is slidably installed within the support frame 3, and the support frame 3 limits the movement of the connecting plate 15, thereby improving the stability of the movement of the connecting plate 15. The drive plate 6, the fixed plate 8, and the ends of the short plate 10 are all rotatably connected via long pins. The driven plate 7 and the middle of the long plate 9 are all rotatably connected via long pins. The ends of the long plate 9 and the short plate 10 are all rotatably connected via short pins. The drive plate 6, the driven plate 7, and the support frame 3 are all slidably connected via the cooperation of a large slider and a large slide rail. The large slider and the drive plate 6 and the driven plate 7... The large slide rail is fixedly connected to the support frame 3. The bottom of the drive plate 6, driven plate 7, and fixed plate 8 are all provided with connecting frames 16. The connecting frames 16 are slidably connected to the drive plate 6, driven plate 7, and fixed plate 8 through the cooperation of small sliders and small slide rails. The small slide rails are fixedly installed at the bottom of the drive plate 6, driven plate 7, and fixed plate 8. The small sliders are fixedly connected to the connecting frames 16. One side of the connecting frames 16 is fixedly connected to the small motor 11. The small motor 11 is electrically connected to the external terminal control equipment. The other side of the connecting frames 16 is fixedly connected to the output end of the bottom of the small cylinder 17. The top of the small cylinder 17 is fixedly connected to the bottom of the drive plate 6, driven plate 7, and fixed plate 8. The small cylinder 17 is electrically connected to the external terminal control equipment.
[0030] When multiple holes need to be drilled at equidistant locations at once, the required drilling interval is determined. The large motor is started, driving the active meshing wheel to rotate. The active meshing wheel drives the driven meshing wheel to rotate via a meshing belt. The driven meshing wheel then drives the threaded rod 4 to rotate under the limit of the support seat 14. This causes the threaded rod 4 to move the threaded sleeve 5, which is fixedly connected to it via a connecting plate 15. Under the limit of the support frame 3 on the connecting plate 15, the moving sleeve 5 drives the drive plate 6 to move along the axis of the threaded rod 4. The drive plate 6 slides on one side of the support frame 3 via the cooperation of a large slide rail and a large slider. The drive plate 6 is rotatably connected to the short plate 10 via a long pin, causing the short plate 10 to move via the short pin. The long plate 9, in turn, moves via the rotatable connection between its long pin and the driven plate 7. The moving plate 7 moves synchronously with the drive plate 6 under the limiting sliding of the large slider and the large slide rail. During this process, the fixed plate 8 remains stationary. Then, the drive plate 6 and the driven plate 7 drive the small motor 11 to move through the connecting bracket 16 slidably installed at their bottom. This causes the small motor 11 to drive the drilling bit 12 to move, thereby adjusting the distance between the hole diameters. This facilitates drilling multiple holes at equidistant positions at one time, improving processing efficiency. After adjustment, the output end of the large air cylinder 2 is extended by starting the air cylinder 2, which can quickly adjust to the approximate range of the target height, reducing the overall adjustment time and bringing the drilling bit 12 closer to the cardboard. Then, the small air cylinder 17 is controlled for fine adjustment, bringing the drilling bit 12 closer to the cardboard. The drilling is performed by rotating the drill bit. Through two-stage adjustment, not only can various cardboard thicknesses be flexibly handled, but the consistency and accuracy of drilling are also improved, thereby improving processing precision.
[0031] Example 3: Based on Example 2, the lower surface of the placement plate 13 is fixedly connected to the collection box 18. The collection box 18 is used to collect the debris from the drilling. Through holes 19 are provided on both sides of the upper surface of the collection box 18 to facilitate the leakage of debris. A groove 20 is provided in the middle of the upper surface of the collection box 18 to facilitate the retraction of the drilling bit 12 and prevent the drilling bit 12 from contacting the placement plate 13.
[0032] The clamping assembly includes a limiting plate 21 with a threaded hole. An adjusting rod 22 is threadedly connected to the limiting plate 21. The bottom of the adjusting rod 22 is fixedly connected to one end of a smooth rod 23. The other end of the smooth rod 23 is fixedly fitted onto the inner ring surface of the limiting bearing 24. The outer ring surface of the limiting bearing 24 is fixedly connected to a support plate 25, thereby allowing the limiting bearing 24 to be installed in a manner where the inner ring rotates and the outer ring is fixed. The lower surface of the support plate 25 is fixedly connected to one end of a buffer 26. The other end of the buffer 26 is fixedly connected to the upper surface of a pressure plate 27. An anti-slip pad 28 is fixedly connected to the lower surface of the pressure plate 27.
[0033] Before drilling, the worker places the cardboard on the upper surface of the placement plate 13. At this time, by twisting the adjusting rod 22, which is threadedly connected to the limiting plate 21, the adjusting rod 22 can move downward. As the adjusting rod 22 moves downward, it drives the light rod 23 to rotate on the inner ring surface of the limiting bearing 24. Thus, through the connection of the limiting bearing 24, the adjusting rod 22 indirectly drives the support plate 25 to move downward. Under the connection of the buffer 26, the support plate 25 drives the pressure plate 27 to move closer to the cardboard until the anti-slip pad 28 presses the cardboard tightly, thereby fixing the cardboard. During this process, the buffer 26 prevents the cardboard from being crushed by excessive pressure. At the same time, the anti-slip pad 28 increases the pressing stability and further protects the cardboard from being crushed. The debris during the drilling process can be drained through the through hole 19, which facilitates subsequent collection. The design of the groove 20 avoids contact between the drilling bit 12 and the placement plate 13.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
