Description

Technical Field

[0001] This invention relates to the field of paper processing equipment technology, and in particular to an automatic notebook paper cutting device and a method for recycling cut waste paper. Background Technology

[0002] Paper cutting equipment is a core supporting equipment in the deep processing of paper products. It is widely used in the cutting and forming of various types of flat paper, such as stationery, office paper, and packaging paper. It is an indispensable key processing equipment in the automated production system of paper products.

[0003] Paper cutting equipment uses internal blades to cut paper and processes it in batches. After processing, the cut paper is sorted and stacked by manual collection. Finally, the operator cleans the paper waste at the output end of the equipment and inside the equipment at regular intervals.

[0004] After the paper cutting equipment finishes processing the paper, the operator needs to be in close contact with the cutting equipment to put the paper waste into the fixed recycling position. During this period, the operator needs to put his / her hands into the cutting equipment or the discharge port to clean up the waste, which is very easy to get injured, exacerbates the safety hazards of the operator, and also greatly reduces the working efficiency of the machine. Summary of the Invention

[0005] To reduce the incidence of accidents caused by operators while cleaning up paper scraps, this invention provides an automatic notebook paper cutting device and a method for recycling cut waste paper.

[0006] In a first aspect, the present invention provides an automatic notebook paper cutting device, which adopts the following technical solution: An automatic notebook paper cutting device includes a cutting device body with a cutting tool mechanism for cutting paper, a bending structure disposed on the cutting tool mechanism and for bending and cutting paper scraps when the cutting tool mechanism cuts the paper, a misalignment pushing mechanism mounted on the cutting device body for tilting and misaligning the paper scraps, and a scrap removal mechanism mounted on the cutting device body for blowing away the tilted and misaligned paper scraps.

[0007] By adopting the above technical solution, the paper to be cut can be cut by the cutting blade mechanism into two parts: standard paper and paper waste. During the cutting process, the bending structure can simultaneously bend or cut the paper waste. Then, the offset pushing mechanism can push the paper waste from the side, making the paper waste tilted. Finally, the equipment automatically blows away the paper waste through the chip removal mechanism. The above equipment can automatically clean up the generated paper waste without the need for manual removal, thus avoiding safety accidents for operators while cleaning paper waste. Furthermore, after the bending and tilting operations, the contact area between adjacent sheets of paper is reduced, and the mutual adsorption force is weakened, so that they can be quickly blown away when finally removed by the blowing mechanism.

[0008] Optionally, the cutting mechanism includes a cutting blade with a main cutting edge at its lower end for cutting the paper; the bending structure includes a secondary cutting edge disposed on one side of the main cutting edge for bending and cutting the paper scraps downwards, the secondary cutting edge being inclined to the main cutting edge; the side of the main cutting edge facing the secondary cutting edge has a guide surface so that the cross-section is inclined after the paper scraps are cut off.

[0009] By adopting the above technical solution, when the cutting blade processes the paper, the accumulated paper is cut by the main cutting edge, and the secondary cutting edge presses down simultaneously, causing multiple bending or cutting of the top surface of the paper waste. In conjunction with the guide push surface on the main cutting edge, the accumulation shape of the paper waste on the side is consistent with the guide push surface, resulting in a certain amount of misalignment between adjacent paper waste, thereby reducing the contact area between adjacent papers. This makes the overall accumulated paper waste form an easy-to-pour and fluffy structure, which is convenient for subsequent processing of paper waste.

[0010] Optionally, the cutting tool mechanism further includes a tool holder for mounting the cutting blade and a drive assembly for driving the cutting blade to move; The blade holder is provided with a guide post, and the cutting blade has a guide groove for the guide post to be inserted and moved. The guide groove is inclined. The cutting blade has a drive rack arranged parallel to the guide groove, and the output end of the drive assembly has a drive gear, with the drive rack meshing with the drive gear.

[0011] By adopting the above technical solution, the drive component drives the drive rack to move through the drive gear, thereby causing the guide column to slide in the inclined guide groove, so that the cutting blade completes the inclined lifting and lowering cutting work on the blade holder along the direction of the guide groove. Compared with the traditional straight lifting and lowering cutting, the inclined cutting can significantly reduce the cutting resistance of the blade, reduce the blade wear, and extend the service life of the blade. At the same time, the horizontal displacement of the cutting blade, combined with the bending effect of the secondary cutting edge, allows the paper waste to be further misaligned.

[0012] Optionally, the misalignment pushing mechanism includes a pushing member and a pushing cylinder that drives the pushing member to move horizontally; after the tool mechanism is reset and raised, the pushing member moves to the side of the paper waste and pushes the paper waste, and the contact point between the pushing member and the paper waste has an inclined pushing surface.

[0013] By adopting the above technical solution, the misalignment pushing mechanism drives the pushing component to push one side of the cut paper waste, and the pushed surface is inclined, so that the adjacent paper waste is misaligned in the lateral direction, thereby reducing the contact area between adjacent paper waste and reducing the mutual adsorption force between adjacent paper waste, so that the paper waste is carried away by the chip removal mechanism.

[0014] Optionally, the main body of the cutting equipment includes a main body base, a processing platform slidably mounted on the main body base, and a sorting mechanism for aligning and sorting the paper; The processing platform has horizontal ventilation channels on both sides and a vertical material unloading channel connected to the ventilation channels. A movable plate is horizontally slidably installed on the processing platform; the top surface of the movable plate is flush with the top surface of the processing platform. The moving plate has a processing state and a material discharge state; in the processing state, the moving plate covers the material discharge channel; in the material discharge state, the moving plate moves horizontally and opens the material discharge channel to allow paper waste to fall into the material discharge channel.

[0015] By adopting the above technical solution, the moving plate of the processing platform can switch process states; when the cutting tool mechanism is cutting, the internal material discharge channel is in a closed state, ensuring that the platform is in a flat and stable state during cutting; when the chip removal mechanism collects paper waste, the moving plate moves to open the material discharge channel, allowing paper waste to fall into the channel and be carried away by the airflow, so that the cutting and chip removal processes do not interfere with each other, and can prevent paper waste from falling into the material discharge channel during the cutting process; at the same time, compared with the method of directly treating paper waste on the processing plane, setting the ventilation channel inside can concentrate and collect paper waste, and paper waste is not easy to spread on the processing platform.

[0016] Optionally, the main body base is horizontally provided with an air inlet and a material outlet, which are located on both sides of the ventilation channel; in the material dropping state, the air inlet is connected to the ventilation channel; The chip removal mechanism includes an air supply source connected to the air inlet and a waste chip collection box connected to the discharge port; the air supply source blows air into the ventilation channel to blow paper waste into the waste chip collection box. The air supply source is connected to the misalignment drive mechanism.

[0017] By adopting the above technical solution, the air supply source can deliver airflow to the ventilation channel to remove paper waste during the material feeding process, and at the same time provide a power source for the misalignment pushing mechanism. The two share a single pneumatic system, which greatly reduces the machine cost.

[0018] Optionally, the processing platform has a processing area for accommodating paper to be cut; in the processing state, there is a gap between the edge of the moving plate and the edge of the processing area, the gap is directly opposite the blade portion at the lower end of the cutting knife, and the gap is connected to the material feeding channel.

[0019] By adopting the above technical solution, when the cutter cuts the paper, the main cutting edge of the cutter can cut into the gap, and the cutting depth exceeds the thickness of the paper, so that all the paper is completely cut off, avoiding any paper residue that is not cut off.

[0020] Optionally, the finishing mechanism includes a lateral leveling component for leveling the paper from both sides, a forward leveling component for leveling the paper from the front, and a top leveling component for flattening the paper from the top. The forward leveling component includes a forward top block that is horizontally slidably installed on the processing platform; the forward top block is located on top of the moving plate; when the moving plate switches from the processing state to the unloading state, the forward top block presses the paper waste against the unloading channel until it is in the open state.

[0021] By adopting the above technical solution, the sorting mechanism can flatten the paper's sides, top, and front, so that the paper can be cut according to processing requirements. Furthermore, during the process of the moving plate switching to the feeding state, the front flattening top block can hold back paper scraps until the feeding channel is opened, preventing paper scraps from falling onto the moving plate before the feeding channel is opened.

[0022] Secondly, this application provides a method for recycling waste paper from an automatic notebook paper cutting device, applied to the aforementioned automatic notebook paper cutting device, and employing the following technical solution: A method for recycling waste paper from an automatic notebook paper cutting device includes: Step 1: Collect the total thickness of the paper to be cut; Step 2: Determine if the total paper thickness is less than the preset baseline processing thickness; Step 3: When the total thickness of the paper is less than the baseline processing thickness, the forward top block is controlled to move away from the paper waste by the preset top block displacement so that the paper waste falls directly into the ventilation channel. Step 4: When the total thickness of the paper is not less than the baseline processing thickness, the paper waste is divided into multiple processing layers in the vertical direction using a preset layering method, and the processing layer thickness of each processing layer is recorded. Step 40: Press down the pre-set cutting blade according to the thickness of the treatment layer, and press the paper waste into the ventilation channel layer by layer from bottom to top. Use the pre-set blowing power to control the paper waste removal mechanism to blow away the paper waste in the ventilation channel.

[0023] By adopting the above technical solution, after the cutting blade cuts the paper, the system identifies the total thickness of the paper and determines the recycling method of paper waste based on the total thickness of the paper. Paper waste with a small thickness falls directly into the ventilation channel, while paper waste with a large thickness is pressed into the ventilation channel layer by layer from bottom to top by the downward force of the cutting blade, so as to avoid the blockage of the ventilation channel caused by the large paper waste falling at once.

[0024] A method for recycling waste paper from an automatic notebook paper cutting device, comprising a layering method including: Step 41: Acquire images of paper scraps after the paper has been cut by the cutting mechanism; Step 42: Analyze the paper waste image to obtain the waste thickness value; Step 43: Determine the expansion ratio based on the waste thickness and the total paper thickness; Step 44: Perform image recognition on the paper waste image to obtain the features and thickness of the cut paper waste, and calculate the thickness of the complete paper waste. Step 45: Calculate the actual thickness of the complete paper scrap corresponding to the thickness of the complete paper scrap based on the expansion ratio; Step 46: When the actual thickness of the complete paper scrap is less than the baseline processing thickness, the paper waste corresponding to the thickness of the complete paper scrap is not separated into layers; Step 47: When the actual thickness of the complete paper scrap is greater than the reference processing thickness, the paper scraps corresponding to the thickness of the complete paper scrap are layered using the reference processing thickness as the unit. Step 48: Layer the paper waste corresponding to the preset cutting paper waste layer thickness. By adopting the above technical solution, after the paper is cut, the paper waste is image-recognized and initially layered according to the cutting status. The uncut paper waste does not need to be layered again depending on its actual thickness, while the cut paper waste can be directly layered according to the set layering thickness because the volume of each paper waste is small. By layering the paper waste using the above method, the layered paper waste can be more easily blown away by the wind and is less likely to remain in the ventilation channel.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The paper to be cut can be cut by the cutting blade mechanism into two parts: standard paper and paper waste. During the cutting process, the bending structure can simultaneously bend or cut the paper waste. Then, the offset pushing mechanism can push the paper waste from the side, making the paper waste tilted. Finally, the equipment automatically blows away the paper waste through the chip removal mechanism. When the cutting blade processes the paper, the piled paper is cut by the main cutting edge, and the secondary cutting edge presses down simultaneously to bend or cut the top surface of the paper waste in multiple places. With the help of the guide push surface on the main cutting edge, a certain amount of misalignment is generated between adjacent paper waste, thereby reducing the contact area between adjacent papers. This makes the piled paper waste form an easy-to-pour and fluffy structure, which is convenient for subsequent processing of paper waste. The moving plate of the processing platform can switch the process state; when the cutting mechanism is cutting, the internal material discharge channel is in a closed state, ensuring that the platform is in a flat and stable state during cutting; when the chip removal mechanism collects paper waste, the moving plate moves to open the material discharge channel, allowing paper waste to fall into the channel and be sent away with the airflow, so that the cutting and chip removal processes do not interfere with each other, and can prevent paper waste from falling into the material discharge channel during the cutting process.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0029] This invention discloses an automatic notebook paper cutting device.

[0030] Reference Figure 1 An automatic notebook paper cutting device includes a cutting device body 1, a sorting mechanism 2, a cutting mechanism 3, and a chip removal mechanism 5. The cutting device body 1 is used to house and install the various mechanisms and components. The sorting mechanism 2 flattens and aligns the paper to be cut. The cutting mechanism 3 cuts the paper to be cut. The chip removal mechanism 5 blows air to clean up the paper waste generated during cutting.

[0031] Reference Figure 1 and Figure 2 In this embodiment, the main body 1 of the cutting equipment includes a main base 11, a main frame 12, and a processing platform 13. The main frame 12 is mounted on the main base 11, and a processing chamber for cutting paper is formed between the two. The processing platform 13 is movably mounted on the main base 11 and is driven by a linear module. A moving channel 111 is provided on the main base 11 for the processing platform 13 to be embedded and move horizontally, and the linear module is located in the moving channel 111. The top surface of the processing platform 13 is flush with the top surface of the main base 11.

[0032] Reference Figure 2 and Figure 3The processing platform 13 has a translation groove 131, within which a moving plate 132 is horizontally mounted. A linear module for driving the moving plate 132 is also installed within the translation groove 131. The top surface of the moving plate 132 is flush with the top surface of the processing platform 13. In this embodiment, the top of the moving plate 132 is the feeding area 1321 for the paper to be cut, and the processing platform 13 is the processing area 133 for the paper to be cut. The length of the processing area 133 is the same as the length of the target paper; that is, the point where the processing platform 13 and the moving plate 132 meet is the cutting position.

[0033] In this embodiment, a material drop channel 1311 is vertically formed on the bottom surface of the translation groove 131. The width of the material drop channel 1311 is the same as the width of the moving plate 132. The material drop channel 1311 is located below the cutting position and on one side of the moving plate 132. A ventilation channel 134 is horizontally formed along the width direction of the processing platform 13, and the ventilation channel 134 penetrates both side walls of the processing platform 13. The ventilation channel 134 is located below the material drop channel 1311 and communicates with the material drop channel 1311.

[0034] The movable plate 132, driven by the linear module, has two states: a processing state and a unloading state. In the processing state, the movable plate 132 is close to the processing area 133 and has a gap between it and the edge of the processing area 133. The movable plate 132 covers the unloading channel 1311, and the gap communicates with the unloading channel 1311. In the unloading state, the movable plate 132 is away from the processing area 133, and the movable plate 132 opens the unloading channel 1311.

[0035] Reference Figure 3 and Figure 4 In this embodiment, the finishing mechanism 2 includes a lateral leveling component 21, a forward leveling component 22, and a top flattening component 23. The lateral leveling component 21 is used to level the paper from both sides, the forward leveling component 22 is used to level the paper from the front, and the top flattening component 23 is used to flatten the paper from the top.

[0036] The lateral leveling assembly 21 includes a push cylinder 211 and a push plate 212. The push cylinder 211 is fixed to the top of the main body base 11, and the push plate 212 is installed at the output end of the push cylinder 211 and can move horizontally on the top of the main body base 11 under the drive of the push cylinder 211. The bottom of the push plate 212 is in contact with the top surface of the main body base 11, and the moving direction of the push plate 212 is perpendicular to the moving direction of the processing platform 13.

[0037] When the paper to be cut is in the processing area 133, the push plate 212 can move horizontally and press against the paper to be cut to complete the lateral flattening and alignment of the paper.

[0038] In this embodiment, there are two lateral leveling components 21, which are symmetrically located on both sides of the processing area 133. Therefore, the lateral leveling components 21 can level the paper from both sides of the paper to be cut through the push plate 212.

[0039] The top flattening assembly 23 includes a linear guide module 231 and a pressure plate 232. The linear guide module 231 is fixedly mounted on the main frame 12, and the pressure plate 232 is fixed to the output end of the linear guide module 231. The linear guide module 231 can drive the pressure plate 232 to move up and down within the processing chamber. The pressure plate 232 is horizontally positioned with its bottom surface being horizontal. Therefore, when the linear guide module 231 drives the pressure plate 232 to press against the bottom of the paper to be cut, the pressure plate 232 can flatten the paper.

[0040] The forward leveling assembly 22 has two sides and is located on both sides of the moving plate 132 and installed along the length of the moving plate 132. The forward leveling assembly 22 includes a forward top block 221 and a rodless cylinder 222. The forward top block 221 is mounted on the slider of the rodless cylinder 222 and can move horizontally on the moving plate 132 under the drive of the rodless cylinder 222. The bottom of the forward top block 221 is in contact with the top surface of the moving plate 132.

[0041] When the automatic paper cutting equipment is started, the moving plate 132 is in the processing state and the feeding area 1321 of the moving plate 132 is outside the processing chamber, and the positive top block 221 is located at the end away from the processing area 133. When the paper to be cut is placed in the feeding area 1321 of the moving plate 132, the positive top block 221 pushes the paper under the drive of the rodless cylinder 222 and pushes the paper to the processing area 133 of the processing platform 13. At this time, the processing platform 13 moves into the processing chamber so that the paper to be cut is located in the processing chamber.

[0042] When the paper is in the processing chamber, the forward top block 221 presses the paper against the inner wall of the processing chamber, the push plate 212 of the lateral leveling component 21 presses the sides of the paper, and the pressure plate 232 of the top leveling component 23 presses the top of the paper, thereby leveling the paper to be cut as a whole within the processing area 133.

[0043] Reference Figure 3 , Figure 5 and Figure 6 In this embodiment, the cutting tool mechanism 3 includes a cutting blade 31, a tool holder 32, and a drive assembly 33.

[0044] The blade holder 32 is fixedly mounted on the main frame 12, and multiple guide posts 321 are provided on the blade holder 32. The cutting blade 31 is flexibly mounted on the blade holder 32. The drive assembly 33 is fixedly mounted on the blade holder 32, and includes a drive motor 331 and a drive gear 332 mounted on the output end of the drive motor 331. The drive assembly 33 is used to drive the cutting blade 31 to move up and down.

[0045] The cutting blade 31 has a guide groove 311, which is inclined. The guide groove 311 corresponds to a guide post 321, and the guide groove 311 and guide post 321 are inserted into each other, allowing the guide post 321 to move relative to each other within the guide groove 311. The cutting blade 31 also has a drive rack 312, which is parallel to the guide groove 311. The drive rack 312 meshes with a drive gear 332.

[0046] When the drive motor 331 drives the drive gear 332 to rotate, the drive gear 332 drives the cutting blade 31 to move up and down along the extension direction of the guide groove 311 through the drive rack 312. During this process, the cutting blade 31 can cut the paper in the processing area 133.

[0047] The lower end of the cutting blade 31 has a main cutting edge 313, the length of which can cover and extend beyond the paper, and the main cutting edge 313 has a bending structure for bending and cutting paper scraps during paper cutting. The bending structure includes a secondary cutting edge 314 integrally disposed on the side of the main cutting edge 313 facing the moving plate 132.

[0048] In this embodiment, the connecting surface between the secondary cutting edge 314 and the main cutting edge 313 has a guide push surface 315, and the outline of the guide push surface 315 is wavy.

[0049] There are multiple secondary cutting edges 314, which are integrally arranged at intervals along the length direction of the main cutting edge 313. At the same time, the secondary cutting edges 314 are inclined on the main cutting edge 313.

[0050] When the drive assembly 33 drives the cutter 31 to cut the paper, the main cutting edge 313 can cut the paper. Furthermore, during the cutting process, the secondary cutting edge 314 can bend and partially cut the paper scraps generated from top to bottom. Simultaneously, the guide surface 315 can push the paper scraps, causing them to be inclined along the length of the processing platform 13. Since the cutter 31 moves downwards at an angle, the paper scraps also become inclined along the width of the processing platform 13.

[0051] Furthermore, when the cutting blade 31 moves downward to cut, the cutting edge of the main cutting edge 313 of the cutting blade 31 can enter the gap between the moving plate 132 and the edge of the processing area 133, so that the paper to be cut can be completely cut.

[0052] Reference Figure 1 and Figure 5 In this embodiment, in order to further increase the inclination of paper waste along the width direction of the processing platform 13 so as to reduce the contact area between adjacent papers, the main body base 11 is provided with a misalignment pushing mechanism 4 for tilting and misaligning the paper waste.

[0053] In this embodiment, the misalignment pushing mechanism 4 includes a pushing member 41 and a pushing cylinder 42. The pushing cylinder 42 is mounted on the main body 1 of the cutting equipment. In this embodiment, it can be located on the main body base 11 or on the main body frame 12. The pushing member 41 is mounted on the push rod of the pushing cylinder 42 and can move horizontally on the main body base 11 under the drive of the pushing cylinder 42. The lower end of the pushing member 41 has an inclined pushing surface on the side facing the processing platform 13, and the pushing member 41 is aligned with the side of the paper waste.

[0054] When the paper to be cut is cut and the tool mechanism 3 is reset and lifted, the push cylinder 42 drives the pusher 41 to move horizontally and push the paper waste. The inclined push surface abuts against the side of the paper waste, so that the side of the paper waste forms an inclined slope 411 corresponding to the inclined push surface.

[0055] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the main base 11 has an air inlet 112 and a discharge port 113, both of which extend horizontally to the moving channel 111. The air inlet 112 and the discharge port 113 are respectively located on both sides of the ventilation channel 134, wherein the air inlet 112 is used to draw in airflow, and the discharge port 113 is used to discharge paper waste. The lint removal mechanism 5 includes an air supply source 51 and a lint collection box 52. The air supply source 51 is located at one end of the air inlet 112 and communicates with the air inlet 112, and the air supply source 51 is used to generate airflow. The lint collection box 52 is located on one side of the discharge port 113 and is used to collect paper waste.

[0056] Reference Figure 1 , Figure 2 and Figure 7 In this embodiment, the air supply source 51 can supply air to the ventilation channel 134, and the air supply source 51 is also connected to the push cylinder 42 of the misalignment push mechanism 4 and provides air to the push cylinder 42.

[0057] When the paper is in the processing chamber, the air inlet 112, the discharge port 113, and the ventilation channel 134 are aligned. The air generated by the air supply source 51 can pass through the air inlet 112, the ventilation channel 134, and the discharge port 113 in sequence.

[0058] Reference Figure 1 , Figure 2 and Figure 3 After the misalignment mechanism 4 completes the tilting and misalignment of the paper waste, the moving plate 132 switches from the processing state to the unloading state. During the state switching process, the paper waste is pressed down by the positive top block 221 and does not move with the moving plate 132. After the moving plate 132 completes the state switching, the unloading channel 1311 is opened, and the paper waste located above the unloading channel 1311 can fall directly into the unloading channel 1311. The paper waste enters the ventilation channel 134 from the unloading channel 1311 and is sent out to the waste collection box 52 by the airflow generated by the air supply source 51.

[0059] Based on the same inventive concept, embodiments of the present invention also disclose a method for recycling waste paper cut by an automatic notebook paper cutting device.

[0060] A method for recycling waste paper from an automatic notebook paper cutting device includes the following steps: Step 1: Collect the total thickness of the paper to be cut.

[0061] The total paper thickness refers to the total thickness of the stacked papers to be cut on the processing platform 13.

[0062] A displacement sensor is installed on the top flattening assembly 23. The displacement sensor can detect the position of the slider at the output end of the linear guide module 231, thereby detecting the lifting distance of the pressure plate 232. The maximum stroke of the pressure plate 232 is the distance it moves from the starting position to abutting the top surface of the processing platform. The maximum stroke of the pressure plate 232 is a fixed value. By detecting the distance that the pressure plate 232 moves from the starting position to abutting the top surface of the paper through the displacement sensor, the difference between this distance and the maximum stroke of the pressure plate 232 can be used to obtain the total thickness of the paper.

[0063] Step 2: Determine whether the total thickness of the paper is less than the preset baseline processing thickness.

[0064] The reference processing thickness refers to the thickness of a single cut of the paper to be cut when the paper waste generated during the cutting process can be directly and quickly removed by the chip removal mechanism 5 and is not easily retained in the ventilation channel 134. The reference processing thickness is obtained and calibrated by technicians through testing.

[0065] By comparing the total thickness of the paper with the baseline processing thickness, it is determined whether paper waste needs to be processed after cutting, so that the paper waste can be processed quickly.

[0066] Step 3: When the total thickness of the paper is less than the baseline processing thickness, the forward top block 221 is controlled to move away from the paper waste by the preset top block displacement so that the paper waste falls directly into the ventilation channel 134.

[0067] If the total thickness of the paper is less than the baseline processing thickness, it means that the paper waste generated by the paper currently being cut is relatively thin and can fall directly into the ventilation channel 134 for processing.

[0068] The displacement of the top block refers to the distance that the forward top block 221 moves away from the paper waste when the paper waste is ready to be processed, as set by the technician. When the forward top block 221 moves away from the paper waste, the paper waste is not pressed down and can fall into the feeding channel 1311 under the action of gravity.

[0069] When the system detects that the total thickness of the paper to be cut is less than the reference processing thickness, after the cutting is completed, the system controls the positive top block 221 to move away from the paper waste according to the top block displacement, so that the paper waste can fall directly into the ventilation channel 134.

[0070] Step 4: When the total thickness of the paper is not less than the baseline processing thickness, the paper waste is divided into multiple processing layers in the vertical direction using a preset layering method, and the processing layer thickness of each processing layer is recorded.

[0071] If the total thickness of the paper is not less than the baseline processing thickness, it indicates that the paper waste generated by the paper currently being cut is quite thick. Directly discharging this paper waste into the ventilation channel 134 at once may cause congestion or blockage, and the paper waste will remain in the channel. Therefore, the process of discharging the paper waste into the ventilation channel 134 needs to be processed. In this embodiment, the system will first use a preset layering method to process the paper waste into layers, and then process each layer of paper waste sequentially. The layering method will not be described in detail here, but will be introduced in detail in subsequent embodiments.

[0072] Step 40: The cutting blade 31 is pressed down according to the preset thickness of the treatment layer, and the paper waste is pressed into the ventilation channel 134 layer by layer from bottom to top. The paper waste in the ventilation channel is blown away by the lint removal mechanism 5 with the preset blowing power.

[0073] In this embodiment, if the thickness of the paper waste is large, after the offset pushing mechanism 4 processes the paper waste, the forward top block 221 will not move away from the paper waste and will always press it tightly. Then the cutting blade 31 will descend again and use the secondary cutting edge 314 of the cutting blade 31 to squeeze the paper waste downward. Each time, the paper waste is squeezed downward a certain distance, which is the thickness of the processing layer. This allows a portion of the paper to fall into the ventilation channel 134 and be blown away by the chip removal mechanism 5. Finally, all the paper waste can be pressed into the ventilation channel 134 by the secondary cutting edge 314 in the order of the processing layer.

[0074] Processing paper in batches according to the processing layer can prevent large pieces of paper waste from falling into and piling up in the ventilation channel 134 at once, which could cause abnormal machine operation.

[0075] The blowing power is the power of the air supply source 51 of the chip removal mechanism 5, which is the equipment parameter preset by the technician. The air supply source 51 blows according to the blowing power, which can blow away a certain amount of paper waste in the ventilation channel 134.

[0076] The layering method includes the following steps: Step 41: Acquire images of paper scraps after the paper has been cut by the cutting mechanism 3.

[0077] The paper scrap image refers to an image obtained by taking a picture of the cut paper scraps using a camera. The camera is mounted on the main base 11, and the camera's shooting angle is perpendicular to the vertical plane where the cutting mechanism 3 is located. At the time of the picture, the paper has just been cut, and the paper scraps are still on top of the moving plate 132.

[0078] After the paper scraps are cut by the cutter 31, the system will acquire an image of the paper scraps.

[0079] Step 42: Analyze the paper waste image to obtain the waste thickness value.

[0080] The waste thickness value refers to the overall thickness of the paper waste generated during cutting.

[0081] The system identifies and analyzes the acquired images of paper waste. It can first obtain the thickness value of the paper waste in the image, and then combine it with the shooting ratio of the paper waste image to obtain the actual thickness value of the waste.

[0082] Step 43: Determine the expansion ratio based on the waste thickness value and the total paper thickness.

[0083] Paper scraps generated after paper cutting will expand in thickness relative to the original total thickness of the paper due to bending and tilting. The expansion ratio refers to the ratio of the scrap thickness to the total thickness of the paper.

[0084] Step 44: Perform image recognition on the paper waste image to obtain the features of the cut paper waste and the thickness of the cut paper waste, and calculate the thickness of the complete paper waste.

[0085] In this embodiment, when the secondary cutting edge 314 presses the paper waste downwards, a portion of the upper layer of paper waste will be directly cut off due to pressure, while a portion of the paper waste at the bottom will remain intact due to less pressure.

[0086] The cut paper scrap feature refers to the upper layer of paper waste that has been broken. The cut paper scrap thickness refers to the thickness value of the cut paper scrap feature. Due to being cut by the secondary cutting blade 314, the cut paper scrap feature appears as multiple short pieces of paper waste. By identifying these pieces of paper waste in the paper waste image, the cut paper scrap feature is first identified, and then analyzed to obtain the cut paper scrap thickness.

[0087] The complete paper scrap thickness refers to the thickness of the portion of the paper scrap that is not broken off by the secondary cutting edge 314. The complete paper scrap thickness is the difference between the scrap thickness and the cut paper scrap thickness.

[0088] Step 45: Calculate the actual thickness of the complete paper scrap corresponding to the thickness of the complete paper scrap based on the expansion ratio.

[0089] The actual thickness of a complete paper scrap refers to the thickness of a complete paper scrap when it is flat. The actual thickness of a complete paper scrap is the product of the thickness of the complete paper scrap and the expansion ratio. In this embodiment, the expansion ratio of the cut paper scrap is slightly larger than that of the uncut paper scrap, but the overall difference is small, and the two can be considered to have the same expansion ratio.

[0090] Step 46: When the actual thickness of the complete paper scrap is less than the baseline processing thickness, the paper waste corresponding to the thickness of the complete paper scrap is not separated into layers.

[0091] When the actual thickness of the intact paper scraps is less than the baseline treatment thickness, the thickness of this part of the paper scraps is relatively small. The intact paper scraps are treated using the same method as in step 3, without the need for stratification.

[0092] Step 47: When the actual thickness of the complete paper scrap is greater than the reference processing thickness, the paper scraps corresponding to the thickness of the complete paper scrap are layered using the reference processing thickness as the unit.

[0093] If the actual thickness of the intact paper scraps is greater than the baseline processing thickness, then the intact paper scraps are layered with the baseline processing thickness as the thickness of each processing layer. The layering method is as follows: calculate the quotient of the actual thickness of the intact paper scraps and the baseline processing thickness. The integer part of the quotient is the number of layers of intact paper scraps with the baseline processing thickness. The remaining intact paper scraps are treated as a separate processing layer, and the thickness of this processing layer is less than the baseline processing thickness.

[0094] Step 48: Layer the paper scraps corresponding to the preset cutting paper scrap layer thickness.

[0095] Because the cut paper scraps are relatively small, they are layered at a fixed thickness, using the same method as for whole paper scraps. The layering thickness is set by technicians to allow the cut paper scraps to be directly discharged into ventilation channel 134 and quickly blown away. This layering thickness is greater than the baseline processing thickness, enabling the cut paper scraps to be processed more quickly.
