Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging technology, specifically to a hole-opening device for corrugated cardboard box processing. Background Technology
[0002] In today's packaging industry, corrugated boxes are a widely used packaging material, and the optimization and innovation of their processing technology has always attracted much attention. With the continuous growth of market demand for diversified and refined packaging products, perforation has become a key processing step.
[0003] In terms of fixing methods, universal clamps are often used. However, due to the lack of adaptability to different materials and thicknesses of corrugated paper, traditional corrugated box punching equipment has exposed many problems in actual use. First, in terms of fixing, most equipment uses simple and universal fixing clamps, which are difficult to adjust flexibly for cartons of different shapes and sizes. Either the fixing is not firm, or the cartons are prone to displacement during the punching process. In the past, most equipment relied on manual experience to judge the punching position. Operators manually started the punching device when the cartons were rotated to the appropriate position. This method is not only inefficient, but also difficult to ensure the consistency of each punching position due to human error, resulting in poor product quality stability. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example
[0024] Please see Figure 1-5 This utility model provides a technical solution: a hole-opening device for corrugated cardboard box processing, comprising:
[0025] The tabletop 1 has a fixing device 2 rotatably connected to its inner wall. The fixing device 2 fixes the workpiece by rotating. The bottom end of the tabletop 1 is fixedly connected to an opening device 3. The opening device 3 makes an opening by rotating the fixing device 2. The cardboard box is placed on the top of the fixing device 2 and fixed. The opening device 3 at the top of the tabletop 1 makes an opening for the corrugated cardboard box by rotating the fixing device 2.
[0026] The fixing device 2 includes a rotating disk 20. A limiting rod 21 is fixedly connected to the bottom end of the rotating disk 20. A linkage disk 22 is rotatably connected to the outer wall of the limiting rod 21. A connecting rod 23 is rotatably connected to the top end of the linkage disk 22 via a round rod, and the bottom end of the round rod is fixedly connected to the top end of the linkage disk 22. A slider 24 is rotatably connected to the end of the connecting rod 23 away from the linkage disk 22. The outer wall of the rotating disk 20 is rotatably connected to the inner wall of the table surface 1. The outer wall of the connecting rod 23 is arranged in a circumferential array along the central axis of the outer wall of the linkage disk 22. The outer wall of the slider 24 is slidably connected to the inner wall of the rotating disk 20. When it is necessary to perform hole-making processing on the corrugated cardboard box, the cardboard box is first placed on the rotating disk 20, and the rotating disk 20 is rotated. Since the bottom end of the rotating disk 20 is fixedly connected to the limiting rod 21, when the rotating disk 20 rotates, it will drive the limiting rod 21 to rotate synchronously. The outer wall of the limiting rod 21 is rotatably connected to the linkage disk 22. The rotation of the limiting rod 21 will cause the linkage disk 22 to make a circular motion around the limiting rod 21. When the linkage disk 22 rotates, it will drive the connecting rod 23 to move. Since the end of the connecting rod 23 away from the linkage disk 22 is rotatably connected to the slider 24, and the outer wall of the slider 24 is slidably connected to the inner wall of the rotating disk 20, the movement of the connecting rod 23 will push the slider 24 to slide on the inner wall of the rotating disk 20. In this way, the circumferentially distributed slider 24 can adaptively move closer to or further away from the carton according to the size of the carton, thereby achieving the initial fixation of cartons of different specifications.
[0027] The inner wall of the slider 24 is slidably connected to a slide rod 25, and the outer wall of the slide rod 25 is fixedly connected to a pad 26. A compression spring 27 is fixedly connected to one end of the pad 26 near the slide rod 25. The outer wall of the slider 24 extends outward through a long rod, and an insertion rod 28 is slidably connected to the inner wall of the long rod. The end of the compression spring 27 away from the pad 26 is fixedly connected to the outer wall of the slider 24. The bottom end of the pad 26 is slidably connected to the top end of the rotating disk 20. The outer wall of the insertion rod 28 is slidably connected to the inner wall of the table surface 1. When the slider 24 approaches the cardboard box, the pad 26 will contact the cardboard box first. Since the shape and surface of the carton may be irregular, the pad 26 will slide on the slide bar 25 according to the actual situation, and the compression spring 27 will be compressed or stretched accordingly, thereby automatically adjusting the fixing force to ensure that the carton is firmly fixed without damaging it due to excessive pressure. The outer wall of the slider 24 extends outward through the long rod, and the inner wall of the long rod is slidably connected to the insertion rod 28. The outer wall of the insertion rod 28 is slidably connected to the inner wall of the table 1. During the movement of the slider 24, the insertion rod 28 slides on the inner wall of the table 1, playing an auxiliary positioning and stabilizing role, ensuring that the entire fixing process is accurate and reliable.
[0028] The opening device 3 includes a support rod 30, with a limiting frame 31 fixedly connected to the bottom end of the support rod 30. An extension rod 32 is slidably connected to the inner wall of the limiting frame 31. A pin 33 is slidably connected to the extension rod 32 and the inner wall of the limiting frame 31. An electric push rod 34 is fixedly connected to the bottom end of the extension rod 32. An opening head 35 is threadedly connected to the bottom end of the electric push rod 34. The bottom end of the support rod 30 is fixedly connected to the table surface 1. The extension rod 32 is slidably connected to the inner wall of the limiting frame 31 at the top of the support rod 30. The extension length of the extension rod 32 within the limiting frame 31 can be changed by sliding the extension rod 32. After adjusting to a suitable height, the pin 33 is inserted into the inner wall of the extension rod 32 and the limiting frame 31 to fix the extension rod 32. An electric push rod 34 is fixedly connected to the bottom end of the extension rod 32. An opening head 35 is threadedly connected to the bottom end of the electric push rod 34.
[0029] The bottom end of the electric push rod 34 is rotatably connected to a rotating wheel 36 via a bracket. The outer wall of the rotating wheel 36 is rotatably connected to a Hall sensor housing 37 via a rotating shaft. The outer wall of the rotating wheel 36 is rotatably connected to the outer wall of the corrugated paper. After the fixing device 2 secures the carton, the electric push rod 34 begins to operate. It can precisely control the downward pressure and depth of the hole-making head 35, ensuring that holes of different materials and thicknesses can be drilled to meet the requirements. When the fixing device 2 rotates the carton, the corrugated paper drives the rotating wheel 36 to rotate. The outer wall of the rotating wheel 36 is rotatably connected to the Hall sensor housing 37 via a rotating shaft, and the internal Hall sensor can monitor the rotation of the rotating wheel 36 in real time.
[0030] When in use, the cardboard box is placed on the top of the fixing device 2 for fixation, and the opening device 3 at the top of the table 1 makes an opening in the corrugated cardboard box by rotating the fixing device 2.
[0031] When it is necessary to process holes in corrugated cardboard boxes, the cardboard box is first placed on the rotating disk 20. The rotating disk 20 is rotated. Since the bottom end of the rotating disk 20 is fixedly connected to the limiting rod 21, the rotation of the rotating disk 20 will drive the limiting rod 21 to rotate synchronously. The outer wall of the limiting rod 21 is rotatably connected to the linkage disk 22. The rotation of the limiting rod 21 will cause the linkage disk 22 to make a circular motion around the limiting rod 21. When the linkage disk 22 rotates, it will drive the connecting rod 23 to move. Since the end of the connecting rod 23 away from the linkage disk 22 is rotatably connected to the slider 24, and the outer wall of the slider 24 is slidably connected to the inner wall of the rotating disk 20, the movement of the connecting rod 23 will push the slider 24 to slide on the inner wall of the rotating disk 20. In this way, the circumferentially distributed slider 24 can adaptively move closer to or further away from the cardboard box according to the size of the cardboard box, thereby achieving the initial fixation of cardboard boxes of different specifications.
[0032] When the slider 24 approaches the carton, the pad 26 will first contact the surface of the carton. Since the shape and surface of the carton may be irregular, the pad 26 will slide on the slide bar 25 according to the actual situation. The compression spring 27 will be compressed or stretched accordingly, thereby automatically adjusting the fixing force. This ensures that the carton is firmly fixed without damaging it due to excessive pressure. The outer wall of the slider 24 extends outward through the long rod. The inner wall of the long rod is slidably connected to the insertion rod 28. The outer wall of the insertion rod 28 is slidably connected to the inner wall of the table 1. During the movement of the slider 24, the insertion rod 28 slides on the inner wall of the table 1, playing an auxiliary positioning and stabilizing role, ensuring that the entire fixing process is accurate and reliable.
[0033] An extension rod 32 is slidably connected to the inner wall of the limiting frame 31 located at the top of the support rod 30. The extension length of the extension rod 32 within the limiting frame 31 can be changed by sliding the extension rod 32. After adjusting to a suitable height, a pin 33 is inserted into the inner wall of the extension rod 32 and the limiting frame 31 to fix the extension rod 32. An electric push rod 34 is fixedly connected to the bottom end of the extension rod 32. The bottom end of the electric push rod 34 is connected to an opening head 35 through a round rod thread.
[0034] Once the fixing device 2 secures the carton, the electric push rod 34 begins operation. It precisely controls the downward pressure and depth of the punch head 35, ensuring that holes of varying materials and thicknesses can be punched to meet requirements. When the fixing device 2 rotates the carton, the corrugated paper drives the rotating wheel 36 to rotate. A Hall sensor housing 37 is rotatably connected to the outer wall of the rotating wheel 36 via a shaft. The internal Hall sensor monitors the rotation of the rotating wheel 36 in real time.
[0035] When the rotating wheel 36 stops rotating, it indicates that the carton has reached the predetermined opening position. At this time, the Hall sensor transmits this signal to the control system. Upon receiving the signal, the control system immediately triggers the electric push rod 34, causing it to push the opening head 35 downwards to perform the opening operation on the corrugated carton. After the opening is completed, the electric push rod 34 drives the opening head 35 upwards to reset, waiting for the next opening command. This cycle repeats, enabling continuous opening processing of the corrugated carton.
