Description

Technical Field

[0001] The embodiments of the present invention relate to the field of packaging box processing technology, specifically, to a cutting machine for packaging box production. Background Technology

[0002] Packaging boxes are used to package products. They can be categorized by material, such as cardboard boxes, metal boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, and corrugated boxes. The main functions of packaging boxes are to ensure product safety during transportation and to enhance the product's perceived quality. The production process of packaging boxes requires cutting raw materials to facilitate subsequent processing and shaping. Current technologies for the cutting process of packaging boxes still need improvement: raw materials are generally transported via conveyor belts throughout the process. This method suffers from inaccurate positioning, and the raw materials may deviate slightly from the standard cutting position. Existing solutions use mechanical limiting and fixing structures, combined with visual positioning technology for correction. However, this design is too costly and has poor reliability. Furthermore, it can cause compression of the raw materials, especially cardboard and corrugated boxes, easily damaging their flatness. Essentially, the mechanical limiting structure cannot handle the plastic compression caused by excessive displacement of raw materials with low motion precision. Visual positioning technology mainly relies on cameras, which cannot meet the requirements of low latency in simultaneous detection and correction. Therefore, a solution is urgently needed.

A crossbar is slidably installed in the middle of the transmission box. Two sets of gear seats are movably sleeved on the outer surface of the crossbar. Gear one and gear two are rotatably installed inside the gear seats. Gear one meshes with gear three, and gear two meshes with gear four.

[0005] Preferably, the cutting seat is installed on the left side of the transmission box, the support seat is installed on the right side of the transmission box, a second guide post is fixedly installed on the right side of the top of the cutting seat, a connecting cylinder located on the upper side of the connecting plate is movably sleeved on the outer surfaces of the first guide post and the second guide post, a sliding plate located below the connecting plate is fixedly installed at the bottom of the connecting cylinder, a pressure block is fixedly installed at the bottom of the sliding plate, a cutter is fixedly installed at the bottom of the connecting plate, a first guide post is fixedly installed inside the fixing frame, and the connecting plate is adapted to be fitted on the outer surface of the first guide post.

[0006] Preferably, the worm gear is rotatably mounted on the bottom of the front transmission box, the drive motor is mounted on the bottom of the right side of the front transmission box, and the output shaft of the drive motor is fixedly connected to the worm gear.

[0007] Preferably, the first pressure roller is fixedly installed on the outer surface of the first roller, the second pressure roller is fixedly installed on the outer surface of the second roller, and limit rings are fixedly installed on both the front and rear sides of the outer surfaces of the first and second pressure rollers. Both the first pressure roller and the second pressure roller are made of rubber blocks.

[0008] Preferably, adapter plates are fixedly installed at both ends of the crossbar, and the adapter plates fit and abut against the inner wall of the transmission box. Springs are movably sleeved at both ends of the outer surface of the crossbar, and the two ends of the springs are elastically connected to the adapter plates and the gear seat, respectively.

[0009] Preferably, gear three and gear four are the same size, gear one and gear two are the same size, and the centers of gear one and gear two are on the same vertical line.

[0010] Preferably, the raw material is placed on the top of the cutting seat and the support seat, and the raw material is clamped between the pressure cylinder one and the pressure cylinder two.

[0011] Preferably, the cutter and the cutting groove are arranged vertically opposite each other, and the cutter is made of carbon tool steel or alloy tool steel.

[0012] Preferably, the axis of the crossbar is horizontally distributed and perpendicular to the axes of roller one and roller two, and the axis of the crossbar is located at the middle of the axes of roller one and roller two.

[0013] Preferably, the drive motor is a high-precision servo motor, and the spring is compressed and disposed on the outer surface of the crossbar.

[0014] The beneficial effects of the embodiments of the present invention are as follows: 1. This device has been redesigned to achieve precise transportation and positioning of raw materials, effectively improving the positioning accuracy of the device. To achieve this, the device is equipped with a transmission box to provide rotational support for roller one and roller two. The pressure roller one, pressure cylinder one, pressure roller two, and pressure cylinder two on the outer surfaces of roller one and roller two squeeze the raw materials to generate friction, ensuring that the raw materials can move precisely in the transportation direction with the rotation of roller one and roller two. A drive motor drives the worm gear to rotate, which directly drives gear four and roller two to rotate. Then, gear one and gear two located inside the transmission box mesh with gear three and gear four respectively, transmitting power to roller one. The precise rotation control of the drive motor enables roller one and roller two to rotate and stop precisely, effectively improving the positioning accuracy of the device.

[0015] 2. Then, this device uses a telescopic rod to drive the mounting frame and roller to rise and fall freely, adapting to raw materials of different thicknesses and materials, thus enhancing the device's applicability. To achieve this, the roller is installed separately inside the mounting frame and driven by the telescopic rod. Simultaneously, gear seats, gear one, and gear two are used to adapt to the meshing transmission of roller one when its height changes. A horizontally positioned crossbar provides horizontal sliding support for the two sets of gear seats. When roller one moves downward, it pushes gear one and gear two located on both sides, causing the gear seats to slide along the surface of the crossbar, compressing the spring. The spring then generates a rebound force on the gear seats, forcing gear one and gear two to always mesh with gear three and gear four, respectively. When roller one moves upward, the spring applies pressure to the gear seats, ensuring that gear three, gear one, gear two, and gear four always mesh sequentially, thus realizing the device's adjustment function to adapt to raw materials of different thicknesses and materials.

[0016] 3. This device also optimizes the cutting mechanism, integrating a function for fixing and limiting the raw material. A pair of connecting plates and a cutter are slidably guided by guide posts. A connecting cylinder and a sliding plate are movably connected to guide post two and guide post one, which are mounted on the top right side of the cutting seat. A pressure block at the bottom of the sliding plate is used to press the raw material and provide constant fixing pressure. To achieve this, the connecting cylinder is positioned on top of the connecting plate, and the connecting plate supports the connecting cylinder. The connecting cylinder and the sliding plate are fixedly connected. This design allows the connecting plate and cutter to stop applying pressure to the sliding plate and pressure block after disengaging from the connecting cylinder when moving downwards. At this point, the pressure block and sliding plate, used to press and fix the raw material, can achieve a constant fixing pressure through their own gravity. Attached Figure Description

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figures 1-7 As shown, a cutting machine for packaging box production according to this disclosure is illustrated, comprising: The support mechanism includes a base 1, a cutting seat 2 and a support seat 4, and the top of the cutting seat 2 is provided with a cutting groove 3; The cutting mechanism includes a fixed frame 11 installed on the top of the cutting base 2, a telescopic rod 12 installed on the top of the fixed frame 11, and a connecting plate 13 fixedly installed on the telescopic end of the telescopic rod 12. The moving mechanism includes two sets of transmission boxes 5 installed on the front and rear sides of the top of the base 1. A roller 21 and a pressure roller 22 are rotatably installed between the two sets of transmission boxes 5. A pressure cylinder 23 is sleeved on the outer surface of the pressure roller 22. A top frame 6 is installed on the top of the transmission box 5. A telescopic rod 7 is installed on the top of the top frame 6. A mounting frame 8 is fixedly installed at the telescopic end of the telescopic rod 7. A roller 18 and a pressure roller 19 are rotatably installed inside the mounting frame 8. A pressure cylinder 20 is sleeved on the outer surface of the pressure roller 19. The transmission box 5 also includes gear 3 58 and gear 4 59, which are fixedly installed at the ends of roller 1 18 and roller 2 21, respectively. A drive motor 51 and a worm gear 52 are installed at the bottom of the front transmission box 5. The worm gear 52 meshes with gear 4 59 located at the front. A crossbar 53 is slidably installed in the middle of the transmission box 5. Two sets of gear seats 55 are movably sleeved on the outer surface of the crossbar 53. Gear 1 56 and gear 2 57 are rotatably installed inside the gear seats 55. Gear 1 56 meshes with gear 3 58, and gear 2 57 meshes with gear 4 59. This redesigned device achieves precise transport and positioning of raw materials, effectively improving the device's positioning accuracy. To achieve this, the device is equipped with a transmission box 5 to provide rotational support for roller 18 and roller 21. The pressure rollers 19, 20, 22, and 23 on the outer surfaces of roller 18 and roller 21 compress the raw materials, generating friction to ensure that the raw materials can move precisely in the transport direction as roller 18 and roller 21 rotate. A drive motor 51 drives the worm gear 52 to rotate, directly driving gear 4 59 and roller 21 to rotate. Then, gears 56 and 57 located inside the transmission box 5 mesh with gears 58 and 59 respectively, transmitting power to roller 18. The precise rotation control of the drive motor 51 enables roller 18 and roller 21 to rotate and stop precisely, effectively improving the device's positioning accuracy.

[0027] Then, this device uses a telescopic rod 7 to drive the mounting frame 8 and roller 18 to rise and fall freely, adapting to raw materials of different thicknesses and materials, thus enhancing the device's applicability. To achieve this, the roller 18 is installed separately inside the mounting frame 8 and driven by the telescopic rod 7. Simultaneously, gear seats 55, gear 56, and gear 57 are used to adapt to the meshing transmission of the roller 18 when its height changes. A horizontally positioned crossbar 53 provides horizontal sliding support for the two sets of gear seats 55. When the roller 18 moves downwards... This will push the gears 56 and 57 located on both sides, causing the gear seat 55 to slide along the surface of the crossbar 53, compressing the spring 54, and using the spring 54 to generate a rebound force on the gear seat 55, forcing the gears 56 and 57 to always mesh with the gears 58 and 59 respectively. When the roller 18 moves upward, the spring 54 applies pressure to the gear seat 55, so that the gears 58, 56, 57 and 59 can always mesh in sequence, and realize the device's adjustment function to adapt to raw materials of different thicknesses and materials.

[0028] In this embodiment, the cutting seat 2 is installed on the left side of the transmission box 5, the support seat 4 is installed on the right side of the transmission box 5, the top right side of the cutting seat 2 is fixedly installed with a guide post 2 10, the outer surfaces of the guide post 1 9 and the guide post 2 10 are movably sleeved with a connecting cylinder 17 located on the upper side of the connecting plate 13, the bottom of the connecting cylinder 17 is fixedly installed with a sliding plate 15 located below the connecting plate 13, the bottom of the sliding plate 15 is fixedly installed with a pressure block 16, the bottom of the connecting plate 13 is fixedly installed with a cutter 14, the inside of the fixing frame 11 is fixedly installed with a guide post 9, and the connecting plate 13 is adapted to be fitted on the outer surface of the guide post 9. This device also optimizes the cutting mechanism, integrating a function for fixing and limiting the raw material. A guide post 9 guides the connecting plate 13 and the cutter 14. A connecting cylinder 17 and a sliding plate 15 are movably connected to a guide post 10 mounted on the top right side of the cutting base 2 and the guide post 9. A pressure block 16 at the bottom of the sliding plate 15 is used to press the raw material and provide constant fixing pressure. To achieve this, the connecting cylinder 17 is positioned on top of the connecting plate 13 and supported by the connecting plate 13. The connecting cylinder 17 and the sliding plate 15 are fixedly connected. This design allows the connecting plate 13 and the cutter 14 to stop pressing on the sliding plate 15 and the pressure block 16 after disengaging from the connecting cylinder 17 when moving downwards. At this point, the pressure block 16 and the sliding plate 15, used to press and fix the raw material, can achieve a constant fixing pressure through their own gravity.

[0029] In this embodiment, the worm gear 52 is rotatably mounted on the bottom of the front transmission box 5, and the drive motor 51 is mounted on the bottom of the right side of the front transmission box 5. The output shaft of the drive motor 51 is fixedly connected to the worm gear 52. The worm gear 52 and the drive motor 51 are used to drive the gear 4 59 to rotate, and directly drive the roller 21 to rotate. The gear 4 59 cannot drive the worm gear 52 to rotate in the reverse direction, thus realizing the one-way self-locking property of the gear 4 59.

[0030] In this embodiment, pressure roller 19 is fixedly installed on the outer surface of roller 18, and pressure roller 22 is fixedly installed on the outer surface of roller 21. Limiting rings 24 are fixedly installed on both the front and rear sides of the outer surfaces of pressure roller 19 and pressure roller 22. Pressure cylinder 10 and pressure roller 22 are both made of rubber blocks. like Figure 3 As shown, pressure cylinder 1 20 and pressure cylinder 2 23 are directly used to contact the surface of the raw material, and the friction generated by the extrusion drives the raw material to be transported, ultimately realizing the cutting function.

[0031] In this embodiment, adapter plates 510 are fixedly installed at both ends of the crossbar 53. The adapter plates 510 are adapted to and abut against the inner wall of the transmission box 5. Springs 54 are movably sleeved at both ends of the outer surface of the crossbar 53. The two ends of the springs 54 are elastically connected to the adapter plates 510 and the gear seat 55, respectively. like Figure 7 As shown, the adapter plates 510 at both ends of the crossbar 53 fit and abut against the inner wall of the transmission box 5. When the height of the gear 3 58 and the roller 18 changes, the height of the crossbar 53 will change by driving it. The adapter plates 510 achieve sliding fit of the crossbar 53 by abutting against the inner wall of the transmission box 5.

[0032] In this embodiment, gear 3 58 and gear 4 59 have the same size, gear 1 56 and gear 2 57 have the same size, and the centers of gear 1 56 and gear 2 57 are on the same vertical line. This device also utilizes the transmission box 5 to guide the mounting frame 8 and roller 18 during lifting and lowering. By using gear 3 58 to mesh with gear 1 56, and through gear 2 57 and gear 4 59 to mesh, and with the guiding support of the crossbar 53 on the gear seat 55, the roller 18 is prevented from deflecting during movement. This design eliminates the guide component at the top of the mounting frame 8, saving space, while utilizing the friction and meshing transmission of gear 3 58, gear 1 56, gear 2 57 and gear 4 59 to achieve the guiding function of roller 18.

[0033] In this embodiment, the raw material is placed on the top of the cutting seat 2 and the support seat 4, and the raw material is clamped between the pressure cylinder 1 20 and the pressure cylinder 23. like Figure 3 As shown, pressure cylinder 1 20 and pressure cylinder 2 23 come into contact with the raw material and change pressure under the action of telescopic rod 1 7, generating sufficient frictional force to drive the transport of the raw material.

[0034] In this embodiment, the cutter 14 and the groove 3 are arranged vertically opposite each other, and the cutter 14 is made of carbon tool steel or alloy tool steel. The cutter 14 is made of carbon tool steel or alloy tool steel, which has high strength and hardness, enabling rapid cutting of raw materials.

[0035] In this embodiment, the axis of the crossbar 53 is horizontally distributed and perpendicular to the axes of roller 18 and roller 21. The axis of the crossbar 53 is located in the middle of the axes of roller 18 and roller 21. The crossbar 53 lies across the inner wall of the transmission box 5, providing sliding support for the gear seat 55 and keeping the gear seat 55 in a horizontal position without tilting.

[0036] In this embodiment, the drive motor 51 is a high-precision servo motor, and the spring 54 is compressed and disposed on the outer surface of the crossbar 53. The drive motor 51 is a high-precision servo motor, which has the advantages of precise rotation and control of stopping, and realizes precise power output to the raw materials. The spring 54 can apply pressure to the gear seat 55, so that gear 1 56 and gear 2 57 are always close to and mesh with gear 3 58 and gear 4 59.

[0037] When this device is in operation: First, place the raw material on the support base 4 and make it abut against the pressure cylinder 23, such as... Figure 3 As shown, the telescopic rod 7 is activated, which drives the mounting frame 8 and roller 18 to move downwards, causing the pressure roller 19 and pressure cylinder 20 to move downwards towards the raw material. Finally, pressure cylinder 20 and pressure cylinder 23 come into contact with the raw material and deform, generating friction. Simultaneously, as... Figure 7 As shown, when roller 18 drives gear 3 58 to move downward, it will push the two sets of gears 1 56, gear 2 57 and gear seat 55 to move horizontally to both sides, compressing spring 54. At the same time, the adapter plate 510, crossbar 53 and gear seat 55 descend synchronously with gear 3 58. Gear 4 59 remains fixed under the one-way self-locking action of worm 52. At this time, gear 3 58, gear 1 56 and gear 2 57 rotate synchronously during the descent. Then, the drive motor 51 is started, driving the worm gear 52, gear four 59, and roller two 21 to rotate. Power is then transmitted to roller one 18 via gear two 57, gear one 56, and gear three 58. Figure 3 As shown, roller 18 and pressure roller 22 rotate in opposite directions at the same time. The friction generated by pressure cylinder 10 and pressure cylinder 23 on the raw material precisely drives the raw material to move in the transport direction. When the raw material moves to the cutting position, the drive motor 51 stops and the raw material stops moving. Finally, the telescopic rod 12 is activated, which drives the connecting plate 13 and the cutter 14 downwards, causing the connecting cylinder 17, the sliding plate 15, and the pressure block 16 to move downwards automatically under the action of gravity. When the connecting plate 13 descends to the height of the connecting cylinder 17, the pressure block 16 and the sliding plate 15 press on the surface of the raw material, providing constant fixing pressure. Subsequently, the cutter 14 moves downwards and enters the cutting groove 3 to complete the cutting.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
