Description

TECHNICAL FIELD

[0001] The present application relates to the field of paperboard processing, in particular to a high-safety paper edge waste removal machine and a paper edge cutting method thereof. BACKGROUND

[0002] In a paperboard slitting production line, after the paperboard passes through the slitting machine, the edge part will form a continuous waste edge strip, which needs to be cut off and discharged in time to avoid winding the equipment or affecting the quality of the finished product. As a key supporting equipment of the slitting production line, the waste removal machine functions to receive the paper edge after slitting, and realizes efficient recycling and environmental protection treatment of waste through cutting and conveying.

[0003] For example, the utility model patent with the patent announcement number CN223354415U discloses an ear edge automatic cutting-off machine, which comprises a main seat body, a transmission assembly, a cutting-off assembly and a driving assembly arranged on the main seat body. The transmission assembly comprises a first transmission roller, a second transmission roller, a third transmission roller and a fourth transmission roller rotatably connected to the main seat body. An inlet roller is rotatably connected to the main seat body. The first transmission roller and the second transmission roller are located at one end of the main seat body close to the inlet roller. The third transmission roller and the fourth transmission roller are located at one end of the main seat body away from the inlet roller. The first transmission roller and the third transmission roller are located above the second transmission roller and the fourth transmission roller. The cutting-off assembly comprises a first cutter roller and a second cutter roller. The outer walls of the first cutter roller and the second cutter roller are each provided with cutter teeth. The cutter teeth of the first cutter roller and the second cutter roller are engaged when they are directly opposite.

[0004] When the first cutter roller and the second cutter roller rotate at the same speed and the cutter teeth are in the relative engagement state, there is a lack of gap between the cutter teeth, which can easily cause the cutter teeth to break or even break due to rigid contact during high-speed cutting, affecting the cutting efficiency and increasing the equipment maintenance cost. When the cutter teeth are adjusted to be staggered, although direct collision can be avoided, under high-speed operation conditions, the cut-off paper edge is easy to be rolled into the gap between the first cutter roller and the second cutter roller, causing jamming, blocking or winding, affecting the production continuity, and even causing the equipment to stop, which needs to be improved. SUMMARY

[0005] In order to improve the problem that when the cutter teeth of the cutter roller are in relative engagement, it is easy to cause breakage due to rigid contact, and when the cutter teeth are staggered, the paper edge is easy to be rolled into the rollers to cause jamming, affecting the production continuity and equipment safety, the present application provides a high-safety paper edge waste removal machine and a paper edge cutting method thereof.

[0006] In the first aspect, the present application provides a high-safety paper edge waste removal machine, which adopts the following technical scheme:

[0007] A high-safety paper edge waste removal machine includes a main body, a first cutter roller and a second cutter roller rotatably connected to the main body, and a drive assembly 1 disposed on the main body. The first cutter roller and the second cutter roller rotate in opposite directions. The drive assembly 1 drives the first cutter roller and the second cutter roller to rotate. The first cutter roller is provided with a first cutting tooth, and the second cutter roller is provided with a second cutting tooth. The second cutter roller is provided with an elastic strip, which is located on one side of the second cutting tooth along the outer periphery of the second cutter roller. When the first cutter roller and the second cutter roller rotate synchronously, the first cutting tooth and the second cutting tooth cut the paper edge in an alternating manner.

[0008] By adopting the above technical solution, when the first and second cutting rollers rotate synchronously, the first and second cutting teeth cut the paper edge in an alternating manner, avoiding chipping due to rigid contact between the first and second cutting teeth. At the same time, during the cutting process, the elastic strip is placed on one side of the paper edge, which can reduce the adsorption effect of the airflow generated by the high-speed rotation of the first and second cutting rollers on the paper edge, preventing the paper edge from tilting towards the cutting roller after cutting, and thus preventing the paper edge from being rolled into the gap between the first and second cutting rollers. This structure reduces the chipping problem caused by the relative meshing of the cutting teeth and the jamming and blockage caused by the paper edge being rolled into the cutting teeth when they are misaligned, improving the safety and continuity of equipment operation, reducing maintenance costs, and meeting the requirements of high efficiency and stability of the paperboard slitting production line.

[0009] Optionally, when the first cutting roller and the second cutting roller rotate synchronously, the first cutting tooth is located between the second cutting tooth and the elastic strip.

[0010] By adopting the above technical solution and utilizing the elastic support of the elastic strip, while the first and second blades are cutting the paper edge in an alternating manner, the paper edge is ensured to be stably pressed between the second blade and the elastic strip, thereby achieving a more thorough and stable cutting effect.

[0011] Optionally, when the first cutting roller and the second cutting roller rotate synchronously, the first cutting tooth is located on the side of the second cutting tooth away from the elastic strip.

[0012] Optionally, the main body is provided with a through hole, which is located between the first cutter roller and the second cutter roller.

[0013] By adopting the above technical solution, during the equipment assembly process, the operator can directly observe the relative positions of the first and second cutting teeth and the elastic strip through the through hole, ensuring that the first cutting tooth can accurately fit into the gap between the second cutting tooth and the elastic strip during operation, thereby ensuring the assembly accuracy and operational stability of the cutting components.

[0014] Optionally, the drive assembly includes a drive wheel, a transmission wheel, a transmission wheel, a transmission belt, and a drive component. The drive wheel is rotatably connected to the main body. The transmission wheel is coaxially mounted on the first cutter roller. The transmission wheel is coaxially mounted on the second cutter roller. The transmission belt is stretched between the drive wheel, the transmission wheel, and the transmission wheel. The drive component drives the drive wheel to rotate.

[0015] By adopting the above technical solution, when the drive component drives the drive wheel to rotate, the frictional resistance between the transmission belt and the drive wheel, the transmission wheel and the transmission wheel can synchronously drive the first cutter roller and the second cutter roller to rotate in opposite directions at the same speed, thereby ensuring the precise cooperation between the first cutter tooth, the second cutter tooth and the elastic strip, and effectively ensuring the synchronicity and stability of the cutting action.

[0016] Optionally, two tearing wheels are rotatably connected to the main body. The two tearing wheels are located on the same side of the first cutting roller and are spaced apart. The main body is provided with a driving component three for driving one of the tearing wheels to rotate. The elastic strip is provided with a chamfer, and the chamfer is located on the side of the elastic strip away from the second cutting tooth.

[0017] By adopting the above technical solution, when the cut paper edge moves towards the tearing wheel under the rotation of the elastic strip, the chamfer can provide a gradual guiding effect on the paper edge, making it easier for the paper edge to smoothly enter the gap between the two tearing wheels.

[0018] Optionally, a feed roller, a first transfer roller, and a second transfer roller are rotatably connected to the main body. The first transfer roller and the second transfer roller are located on the side of the first cutter roller away from the tearing wheel, and the first transfer roller is located above the second transfer roller. The feed roller is located on the side of the first transfer roller away from the first cutter roller. A conveyor belt is tensioned on the outer side of the feed roller and the second transfer roller. The main body is provided with a second drive assembly, which drives the feed roller, the first transfer roller, and the second transfer roller to rotate.

[0019] By adopting the above technical solution, the paper edge can be stably guided to enter from the feed roller side and transported by the conveyor belt to the space between the first cutter roller and the second cutter roller for cutting.

[0020] Optionally, the outer peripheral wall of the first transfer roller is provided with bristles.

[0021] By adopting the above technical solution, the friction between the first transmission roller and the paper edge is increased, and the waste edge is smoothly pulled into the space below the first transmission roller, so that the paper edge feeding is stable.

[0022] Optionally, the second drive assembly includes a drive shaft rotatably connected to the main body, a plurality of rotating shafts coaxially disposed on the first and second transmission rollers respectively, a second transmission belt tensioned between the drive shaft and each rotating shaft, and a second drive member disposed on the main body, wherein the second drive member drives the drive shaft to rotate.

[0023] By adopting the above technical solution, when the drive component 2 drives the drive shaft to rotate, it can simultaneously drive the feed roller, the first transmission roller and the second transmission roller to rotate at the same time, thereby ensuring that the conveyor belt stably and continuously transports the paper edge, and ensuring the synchronicity and stability of the paper edge transport.

[0024] Secondly, this application provides a paper edge cutting method for a high-safety paper edge waste removal machine, which adopts the following technical solution:

[0025] A paper edge cutting method for a high-safety paper edge waste removal machine includes the following steps: the drive assembly drives the first cutter roller and the second cutter roller to rotate synchronously in opposite directions, feeding the paper edge to be processed into the gap between the first cutter roller and the second cutter roller. As the first cutter roller and the second cutter roller continue to rotate, the cutting edges of the first cutter tooth and the second cutter tooth interlock and cut the paper edge.

[0026] By adopting the above technical solution, the elastic strip is always placed on one side of the paper edge during the cutting process. This not only buffers the impact force between the blade teeth and avoids the problem of blade breakage caused by rigid contact, but also reduces the influence of the airflow adsorption effect generated by the high-speed rotation of the cutting roller, preventing the paper edge from tilting and getting caught in the direction of the cutting roller after being cut. This effectively improves the defects of blade teeth being prone to breakage and paper edge being prone to jamming, and improves the safety, continuity and efficiency of equipment operation.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the first and second cutter rollers rotate synchronously, the first cutter tooth is inserted into the gap between the second cutter tooth and the elastic strip to cut the paper edge, avoiding the rigid contact of the cutter teeth that would cause chipping. At the same time, the elastic strip is placed on one side of the paper edge to reduce the influence of the airflow adsorption generated by the high-speed rotation of the cutter rollers, preventing the paper edge from tilting towards the cutter roller side after being cut and getting into the gap between the rollers. This reduces the chipping problem caused by the relative meshing of the cutter teeth and the jamming and blockage caused by the paper edge getting into the gap when the cutter teeth are misaligned. It improves the safety and continuity of equipment operation, reduces maintenance costs, and meets the requirements of high efficiency and stability of the paperboard slitting production line.

[0029] 2. By setting through holes, operators can directly observe the relative positions of the first and second cutting teeth and the elastic strip during the equipment assembly process, thereby ensuring the assembly accuracy and operational stability of the cutting components;

[0030] 3. By setting a chamfer, when the cut paper edge moves towards the tearing wheel under the rotation of the elastic strip, the chamfer can provide a gradual guiding effect on the paper edge, making it easier for the paper edge to smoothly enter the gap between the two tearing wheels.

[0040] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0041] Example 1

[0042] This application discloses a high-safety paper edge waste removal machine. (Refer to...) Figures 1-4 The high-safety paper edge waste removal machine includes a main body 1, a first cutter roller 2, a second cutter roller 3, and a drive assembly 4. The first cutter roller 2 and the second cutter roller 3 are both rotatably connected to the main body 1, and the first cutter roller 2 is located above the second cutter roller 3. The rotation axes of the first cutter roller 2 and the second cutter roller 3 are parallel to each other, and the rotation directions of the first cutter roller 2 and the second cutter roller 3 are opposite. Two blade teeth 5 are installed on the first cutter roller 2, and the two blade teeth 5 are located on opposite sides of the first cutter roller 2. Two blade teeth 6 are installed on the second cutter roller 3, and the two blade teeth 6 are located on opposite sides of the second cutter roller 3.

[0043] Reference Figures 1-4 Two elastic strips 7 are also fixed on the second cutting roller 3. The positions of the two elastic strips 7 correspond one-to-one with the positions of the two blade teeth 6. Each elastic strip 7 is located on the same side of the corresponding blade tooth 6 along the outer periphery of the second cutting roller 3, and there is a gap between each elastic strip 7 and the corresponding blade tooth 6. A chamfer 71 is formed on the outer wall of each elastic strip 7. The chamfer 71 is located on the side of the elastic strip 7 away from the blade tooth 6. When the first cutting roller 2 and the second cutting roller 3 rotate synchronously, the blade tooth 5 and the blade tooth 6 cut the paper edge in an alternating manner. In this embodiment, the elastic strip 7 is located on the side of the corresponding blade tooth 6 along the rotation direction of the second cutting roller 3. When the first cutting roller 2 and the second cutting roller 3 rotate synchronously, the blade tooth 5 is located between the blade tooth 6 and the corresponding elastic strip 7. The elastic strip 7 is made of polyurethane.

[0044] It should be noted that in actual use, the ends of both the first cutter tooth 5 and the second cutter tooth 6 are machined with bevels, and the bevels extend from the cutting edge of the first cutter tooth 5 / second cutter tooth 6 towards the back of the blade. During the synchronous counter-rotation of the first cutter roller 2 and the second cutter roller 3, when the first cutter tooth 5 and the second cutter tooth 6 enter the interlocking shearing position, the contact area between the two is not the bevel, but the vertical area of ​​the back of the blade where the first cutter tooth 5 and the second cutter tooth 6 are located. At this time, the above-mentioned vertical areas abut against each other, forming a force structure similar to the interlocking of scissor blades. The paper edge is cut off by the shearing action between the vertical surfaces of the first cutter tooth 5 and the second cutter tooth 6. The bevel setting is conducive to the smooth transition of the first cutter tooth 5 and the second cutter tooth 6 when entering and exiting the shearing position, avoiding interference, and at the same time, it helps to guide the paper edge into the shearing area, improving the stability and continuity of the cutting process.

[0045] Reference Figures 1-4Two tear-off wheels 15 are rotatably connected to the main body 1. The two tear-off wheels 15 are located on the same side of the first cutter roller 2 and are arranged vertically at intervals. The rotation axis of the tear-off wheel 15 is parallel to the rotation axis of the first cutter roller 2. A drive component 3 16 is fixed on the main body 1. The output shaft of the drive component 3 16 is coaxially fixed with one of the tear-off wheels 15. The drive component 3 16 drives the tear-off wheel 15 to rotate. In this embodiment, the drive component 3 16 is a motor.

[0046] Reference Figures 1-4 The drive assembly 4 drives the first cutter roller 2 and the second cutter roller 3 to rotate. The drive assembly 4 includes a drive wheel 41, a transmission wheel 42, a transmission wheel 43, a transmission belt 44, and a drive component 45. The drive wheel 41 is rotatably connected to the main body 1, and the rotation axis of the drive wheel 41 is parallel to the rotation axis of the first cutter roller 2. The transmission wheel 42 is coaxially fixed to the first cutter roller 2, and the transmission wheel 43 is coaxially fixed to the second cutter roller 3. The transmission belt 44 is tensioned between the drive wheel 41, the transmission wheel 42, and the transmission wheel 43. The drive component 45 is fixed to the main body 1, and the output shaft of the drive component 45 is coaxially fixed to the drive wheel 41. The drive component 45 drives the drive wheel 41 to rotate. In this embodiment, the drive component 45 is a motor.

[0047] When the drive component 45 drives the drive wheel 41 to rotate, the frictional resistance between the drive belt 44 and the drive wheel 41, the drive wheel 42 and the drive wheel 43 can synchronously drive the first cutter roller 2 and the second cutter roller 3 to rotate in opposite directions at the same speed.

[0048] Reference Figures 1-4 A through hole 11 is provided on the outer side wall of the main body 1. The through hole 11 is located between the first cutter roller 2 and the second cutter roller 3. During the equipment assembly process, the operator can directly observe the relative positions between the first cutter tooth 5, the second cutter tooth 6 and the elastic strip 7 through the through hole 11, ensuring that the first cutter tooth 5 can be accurately embedded in the gap between the second cutter tooth 6 and the elastic strip 7 in the running state, thereby ensuring the assembly accuracy and running stability of the cutting component.

[0049] Reference Figures 1-4 The main body 1 is rotatably connected to a feed roller 8, a first transmission roller 9, and a second transmission roller 10. The first transmission roller 9 and the second transmission roller 10 are located on the side of the first cutter roller 2 away from the tearing wheel 15, and the first transmission roller 9 is located above the second transmission roller 10. The rotation axes of the first transmission roller 9 and the second transmission roller 10 are parallel to the rotation axis of the first cutter roller 2. The outer peripheral wall of the first transmission roller 9 is covered with bristles 12. The bristles 12 increase the friction between the first transmission roller 9 and the paper edge, and pull the waste edge smoothly into the space below the first transmission roller 9, so as to stabilize the paper edge feeding.

[0050] Reference Figures 1-4The feed roller 8 is located on the side of the transfer roller 9 away from the first cutter roller 2, and the rotation axis of the feed roller 8 is parallel to the rotation axis of the transfer roller 10. A conveyor belt 13 is tensioned on the outer side of the feed roller 8 and the transfer roller 10.

[0051] Reference Figures 1-4 A second drive assembly 14 is installed on the main body 1. The second drive assembly 14 drives the feed roller 8, the first transfer roller 9, and the second transfer roller 10 to rotate. The second drive assembly 14 includes a drive shaft 141, several rotating shafts 142, a second transmission belt 143, and a second drive component 144. The drive shaft 141 is rotatably connected to the main body 1, and the rotation axis of the drive shaft 141 is parallel to the rotation axis of the feed roller 8. Several rotating shafts 142 are coaxially fixed on the first transfer roller 9 and the second transfer roller 10, respectively. The second transmission belt 143 is tensioned between the drive shaft 141 and each rotating shaft 142. The second drive component 144 is fixed on the main body 1. The output shaft of the second drive component 144 is coaxially fixed with the drive shaft 141. The second drive component 144 drives the drive shaft 141 to rotate. In this embodiment, the second drive component 144 is a motor.

[0052] The implementation principle of a high-safety paper edge waste removal machine in Embodiment 1 of this application is as follows:

[0053] When the first cutter roller 2 and the second cutter roller 3 rotate synchronously, the first cutter tooth 5 and the second cutter tooth 6 cut the paper edge in an alternating manner, avoiding chipping due to rigid contact between the first cutter tooth 5 and the second cutter tooth 6. At the same time, during the cutting process, the elastic strip 7 is placed on one side of the paper edge, which can reduce the adsorption effect of the airflow generated by the high-speed rotation of the first cutter roller 2 and the second cutter roller 3 on the paper edge, preventing the paper edge from tilting towards the cutter roller after cutting, and thus preventing the paper edge from being rolled into the gap between the first cutter roller 2 and the second cutter roller 3. This structure reduces the chipping problem caused by the relative meshing of the cutter teeth and the jamming and blockage caused by the paper edge being rolled into the cutter teeth when they are misaligned, improving the safety and continuity of equipment operation, reducing maintenance costs, and meeting the requirements of high efficiency and stability of the paperboard slitting production line.

[0054] Embodiment 1 of this application also discloses a paper edge cutting method for a high-safety paper edge waste removal machine, including the following steps: the drive assembly 4 drives the first cutter roller 2 and the second cutter roller 3 to rotate synchronously in opposite directions, and feeds the paper edge to be processed into the gap between the first cutter roller 2 and the second cutter roller 3. As the first cutter roller 2 and the second cutter roller 3 continue to rotate, the cutting edges of the first cutter tooth 5 and the second cutter tooth 6 interlock and cut each other to complete the cutting of the paper edge.

[0055] The implementation principle of the paper edge cutting method of the high-safety paper edge waste removal machine in Embodiment 1 of this application is as follows:

[0056] During the cutting process, the elastic strip 7 is always placed on one side of the paper edge, which not only buffers the impact force between the blade teeth and avoids the problem of blade breakage caused by rigid contact, but also reduces the influence of the airflow adsorption generated by the high-speed rotation of the cutter roller, preventing the paper edge from tilting and getting caught in the direction of the cutter roller after being cut. This effectively improves the defects of easy blade breakage and easy paper edge jamming, and improves the safety, continuity and efficiency of equipment operation.

[0057] Example 2

[0058] Reference Figures 5-6 The difference from Embodiment 1 is that when the first cutting roller 2 and the second cutting roller 3 rotate synchronously, the first cutting tooth 5 is located on the side of the second cutting tooth 6 away from the elastic strip 7.

[0059] Example 3

[0060] Reference Figures 7-8 The difference from Embodiment 1 is that the elastic strip 7 is located on the side of the corresponding blade tooth 6 along the reverse rotation direction of the second cutting roller 3.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
