Description

Technical Field

[0001] This utility model relates to the field of cardboard packaging technology, and in particular to a cardboard packaging creasing machine. Background Technology

[0002] In the process of carton packaging production, the creasing machine is a key piece of equipment, mainly used to creasing the surface of the cardboard for subsequent folding and shaping. The creasing machine is also known as a flatbed creasing and cutting machine, which is a special equipment for creasing and cutting various ordinary cardboard, corrugated cardboard, plastic sheets and leather products.

[0003] An existing technology provides a cardboard packaging creasing machine that uses two vertical plates slidably connected inside the machine body. The bottom of the two vertical plates is fixed to a horizontal plate, and the top is fixed to the carton body. This device uses an adjustment knob in the adjustment mechanism to drive a worm gear, which in turn drives a worm wheel. The worm wheel drives a pin shaft, which in turn drives a cam. The cam drives connecting columns, which in turn drive connecting blocks, which in turn drive upright columns. The upright columns on both sides cause sliders to slide in grooves, thus moving the support frame and allowing adjustment of the position of the creasing rollers on both sides. This adjustment method reduces adjustment steps, improves adjustment efficiency, and consequently enhances the working efficiency of the creasing machine.

[0004] However, the device has obvious shortcomings in practical applications. On the one hand, the placement platform for loading cartons lacks a limiting structure for the cartons. When the placement platform is moved, the cartons are prone to displacement, which directly affects the effect of the carton creasing, resulting in inaccurate creasing position or poor creasing quality. On the other hand, each loading requires the staff to manually push the cartons, which undoubtedly increases the physical exertion of the staff and reduces production efficiency.

[0005] Therefore, it is necessary to provide a carton packaging creasing machine to solve the above-mentioned technical problems. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] First Embodiment

[0026] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1A schematic diagram of the structure of a first embodiment of a carton packaging creasing machine provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the workbench. Figure 3 for Figure 1 The diagram shows the support frame structure. Figure 4 for Figure 1 The diagram shows the structure of the feeding assembly. A carton packaging creasing machine includes: a worktable 1, a slide groove 11 on the top of the worktable 1, a drive motor 12 fixedly installed at one end of the worktable 1, a lead screw 13 fixedly installed at the output end of the drive motor 12, and one end of the lead screw 13 rotatably connected to one side of the inner side of the slide groove 11;

[0027] The feeding assembly 2 is disposed on the top of the workbench 1. The feeding assembly 2 includes a placement plate 21. The bottom of the placement plate 21 is threaded to the outer side of the lead screw 13. Both ends of the top of the placement plate 21 are provided with moving grooves 22. Both sides of the top of the placement plate 21 are provided with moving plates 23. The bottom of the moving plates 23 is slidably connected to the inner side of the moving grooves 22. A support plate 25 is fixedly installed on the top of the moving plates 23. A first drive telescopic member 26 is fixedly installed on the top of the support plate 25. A clamping plate 27 is fixedly installed on the bottom of the first drive telescopic member 26.

[0028] A support frame 3 is fixedly installed on the top of the workbench 1. A second drive telescopic component 31 is fixedly installed on the top of the support frame 3. An adjustment plate 4 is fixedly installed on the bottom of the second drive telescopic component 31. Both ends of the bottom of the adjustment plate 4 are provided with buffer components 44. The bottom of both buffer components 44 is provided with pressure rollers 45.

[0029] Guide rods 32 are fixedly installed at both ends of the top of the adjusting plate 4. The guide rods 32 are slidably connected to the inside of the top of the support frame 3. A sliding cavity 41 is opened at the bottom of the adjusting plate 4. A bidirectional threaded rod 42 is rotatably connected to the inner side of the sliding cavity 41. A moving block 43 is threadedly connected to both ends of the outer side of the bidirectional threaded rod 42. The moving block 43 is set at the top of the buffer 44.

[0030] Guide rails 14 are fixedly installed on both sides of the top of the workbench 1, and the bottom of the placement plate 21 is slidably connected to the outer side of the guide rails 14.

[0031] A locking screw 24 is internally threaded at one end of the movable plate 23, and one end of the locking screw 24 abuts against the side of the placement plate 21.

[0032] When creasing cardboard of different thicknesses, the second drive telescopic component 31 is activated, which pushes the adjusting plate 4 downward. The adjusting plate 4 drives the buffer component 44 and the pressure roller 45 to descend until the bottom of the pressure roller 45 abuts against the top of the cardboard.

[0033] During the process of the pressure roller 45 contacting the cardboard, the buffer 44 plays a buffering role to avoid the pressure roller 45 causing a hard impact on the cardboard; at the same time, the guide rod 32 at the top of the adjusting plate 4 slides inside the top of the support frame 3 to ensure the smoothness of the lowering process of the adjusting plate 4.

[0034] If it is necessary to adjust the distance between the two pressure rollers 45, the bidirectional threaded rod 42 can be rotated. The moving blocks 43 connected to the two ends of the outer side of the bidirectional threaded rod 42 will move towards or away from each other in the sliding cavity 41, thereby driving the buffer 44 and the pressure rollers 45 to move, so as to adjust the position of the pressure rollers 45 to adapt to the creasing requirements of different sizes of cardboard.

[0035] The working principle of the cardboard box creasing machine provided by this utility model is as follows:

[0036] When in use, the user places the cardboard on top of the placement plate 21, then moves the two movable plates 23 so that one side of the two movable plates 23 is attached to the side of the cardboard. Then, the user turns the locking screw 24 so that one end of the locking screw 24 abuts against the side of the placement plate 21, thereby initially limiting the cardboard. Then, the first drive telescopic component 26 is activated, which drives the clamping plate 27 to move downward, so that the clamping plate 27 tightly presses the cardboard, further fixing the position of the cardboard and preventing it from moving in subsequent operations.

[0037] Then, the drive motor 12 is started, and the drive motor 12 drives the lead screw 13 to rotate. Since the bottom of the placement plate 21 is threadedly connected to the lead screw 13, and the bottom of the placement plate 21 is also slidably connected to the guide rails 14 on both sides of the top of the worktable 1, the rotation of the lead screw 13 will cause the placement plate 21 to move along the guide rails 14 toward the creasing mechanism; until the bottom of the pressure roller 45 rolls on the top of the cardboard, thereby creasing the cardboard.

[0038] At this time, the second drive telescopic component 31 is activated, which pushes the adjusting plate 4 to move downward. The adjusting plate 4 drives the buffer component 44 and the pressure roller 45 to descend. During the process of the pressure roller 45 contacting the cardboard, the buffer component 44 plays a buffering role to avoid the pressure roller 45 causing a hard impact on the cardboard. At the same time, the guide rod 32 at the top of the adjusting plate 4 slides inside the top of the support frame 3 to ensure the smoothness of the descent of the adjusting plate 4.

[0039] If it is necessary to adjust the distance between the two pressure rollers 45, the bidirectional threaded rod 42 can be rotated. The moving blocks 43 connected to the two ends of the outer side of the bidirectional threaded rod 42 will move towards or away from each other in the sliding cavity 41, thereby driving the buffer 44 and the pressure rollers 45 to move, so as to adjust the position of the pressure rollers 45 to adapt to the creasing requirements of different sizes of cardboard.

[0040] Compared with related technologies, the cardboard packaging creasing machine provided by this utility model has the following beneficial effects:

[0041] Through the coordinated operation of the drive motor 12 and lead screw 13, the drive motor 12 drives the lead screw 13 to rotate during use, realizing the automatic movement of the placement plate 21. This eliminates the need for manual pushing of the cardboard by the staff, greatly reducing the physical exertion of the staff and improving production efficiency. Furthermore, through the moving plate 23, locking screw 24, and clamping plate 27 in the feeding assembly 2, the cardboard can be limited and fixed in multiple directions, effectively solving the problem of easy displacement during carton feeding in the prior art. This ensures the stability of the cardboard during movement and creasing, thereby making the creasing position accurate and improving the creasing quality.

[0042] Second Embodiment

[0043] Please refer to the following: Figure 5 Based on the first embodiment of this application, which provides a cardboard packaging creasing machine, the second embodiment of this application proposes another cardboard packaging creasing machine. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0044] Specifically, the second embodiment of this application provides a different carton packaging creasing machine in that the cushioning member 44 of the carton packaging creasing machine includes a fixed tube 441, a positioning plate 443 is slidably connected to the inner side of the fixed tube 441, an extension rod 442 is fixedly installed at the bottom of the positioning plate 443, and a spring 444 is fixedly installed at the top of the positioning plate 443.

[0045] The top of the fixed tube 441 is fixedly installed on the bottom of the movable block 43, and the bottom of the extension rod 442 is fixedly installed on the top of the pressure roller 45.

[0046] The working principle of the cardboard box creasing machine provided by this utility model is as follows:

[0047] When the adjusting plate 4 drives the pressure roller 45 to move downward and contact the cardboard, the pressure roller 45 is subjected to the reaction force of the cardboard. The extension rod 442 will push the positioning plate 443 upward to slide inside the fixed tube 441. At this time, the spring 444 at the top of the positioning plate 441 is compressed. The elastic deformation of the spring 444 generates a buffer force, which is transmitted to the pressure roller 45 through the extension rod 442 and the positioning plate 443, thereby relieving the hard squeezing of the cardboard by the pressure roller 45.

[0048] During the creasing process, if the cardboard surface is uneven or the thickness fluctuates, the buffering effect of the spring 444 allows the pressure roller 45 to adaptively adjust the pressure, avoiding damage to the cardboard or uneven creasing depth due to excessive pressure. When the pressure roller 45 completes the creasing action and rises with the adjusting plate 4, the spring 444 restores its deformation, pushes the positioning plate 443 and the extension rod 442 to reset, and returns the pressure roller 45 to its initial position.

[0049] Compared with related technologies, the cardboard packaging creasing machine provided by this utility model has the following beneficial effects:

[0050] The buffer 44, composed of a fixed tube 441, a positioning plate 443, an extension rod 442, and a spring 444, can effectively absorb the impact force when the pressure roller 45 comes into contact with the cardboard, compared to the traditional rigid indentation structure. This reduces wrinkles or cracks in the cardboard caused by compression and improves the flatness and aesthetics of the indentation surface.

[0051] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
