Description

Technical Field

[0001] The present invention relates to the technical field of corrugated paper manufacturing, and specifically to a device and process for manufacturing renewable ultra-low grammage high-strength corrugated paper. Background Art

[0002] Renewable ultra-low grammage high-strength corrugated paper is made from renewable resources and is a low-grammage and high-strength corrugated paper produced through a special process. Compared with traditional corrugated paper, it has a lower grammage but the same strength, which helps to reduce transportation costs and resource consumption.

[0003] In the production process of corrugated board, the cross-cutting machine is a key device for cutting the continuously produced corrugated board into a set length. Since the recycled paper fibers are short, they are prone to fragmentation when cut by the flat knife of the cross-cutting machine, resulting in paper scraps during cutting. The accumulation of paper scraps will increase the frictional resistance between the blade and the board, leading to rapid dulling of the cutting edge and an increase in the frequency of grinding or replacement. For this reason, we propose a device and process for manufacturing renewable ultra-low grammage high-strength corrugated paper. Summary of the Invention

[0004] The purpose of the present invention is to provide a device and process for manufacturing renewable ultra-low grammage high-strength corrugated paper.

[0014] A manufacturing process using the above device includes the following steps:

[0015] S1. Adjust the distance between the pressure rollers through the electric push rod to adapt to the width of the corrugated paper;

[0019] S5. When the cutting seat returns, the linkage negative pressure mechanism adsorbs the paper scraps and conveys them to the waste paper recycling device.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. By arranging symmetrically distributed adsorption boxes and a linkage negative pressure mechanism outside the cutting knife, when the cutting knife moves up with the cutting seat, the cutting seat drives the piston plate to move up in the adsorption box through the piston rod, thereby forming a negative pressure in the adsorption box. The debris generated by the cutting knife cutting the corrugated paper is sucked into the communication box by the suction head and the suction pipe. Subsequently, when the cutting knife moves down, the piston plate squeezes the air in the adsorption box, so that the paper scraps and dust collected in the communication box are concentrated and recycled through the exhaust pipe after being guided by the communication box, avoiding the accumulation of paper scraps after the cutting knife cuts.

[0022] 2. In the present invention, a cleaning block with bristles that can move back and forth is provided on the cutting table. When the cutting knife moves downward, the cutting seat drives the pressure rod to slide downward in the through-hole of the cutting table. During this process, the fixed rod and the slider drive the cleaning block to reciprocate under the guidance of the triangular guiding block and the extrusion and reset of the compression spring to remove the dust at the cutting part of the corrugated paper, which can reduce the wear of the cutting knife caused by the dust at the cutting part of the corrugated paper.

[0023] 3. In the present invention, the distance between the pressing rollers is adjusted by the electric push rod to adapt to the width of the corrugated paper; the height of the pressing roller is adjusted by the second drive box to adapt to the thickness of the corrugated paper; the cutting misalignment caused by the sliding of the cardboard is reduced, and the cutting accuracy is ensured.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1: Please refer to Figure 1 - Figure 9 , a renewable ultra-low gram weight high-strength corrugated paper manufacturing device shown in the figure, including: a support frame 1, an adsorption box 8, an adjusting device 14, a cleaning assembly 19 and a linkage negative pressure mechanism 22. A roller conveyor line 2 is arranged in the support frame 1, a cutting table 3 is fixedly arranged in the support frame 1, a cutting frame 4 is fixedly arranged on the top of the cutting table 3, a first drive box 5 is fixedly arranged on the top of the cutting frame 4, a cutting seat 6 is installed at the output end of the first drive box 5, and a cutter 7 is installed at the bottom of the cutting seat 6; The support frame 1 serves as the skeleton of the overall device, integrating core components such as the roller conveyor line 2 and the cutting table 3, ensuring accurate positioning of each component, reducing vibration interference, and improving cutting stability; The roller conveyor line 2 realizes the continuous conveying of corrugated paper, the cutting table 3 provides rigid support, and cooperates with the cutter 7 driven by the first drive box 5 to complete efficient cutting, which is suitable for high-speed production scenarios;

[0036] There are two adsorption boxes 8, which are symmetrically fixed on the outside of the cutting frame 4. The bottom of the adsorption box 8 is fixedly connected with an elastic threaded box 9. The bottom of the elastic threaded box 9 is fixedly connected with a communication box 10. An air suction pipe 11 is fixedly arranged outside the air suction port of the communication box 10. The air suction end of the air suction pipe 11 is fixedly provided with an air suction head 12. The two air suction heads 12 are symmetrically arranged on both sides of the cutting knife 7. An exhaust pipe 13 is fixedly arranged outside the air outlet of the communication box 10. The exhaust pipe 13 is communicated with an external waste paper recycling device; the air suction heads 12 are symmetrically distributed on both sides of the cutting knife 7, directly aiming at the cutting area, and sucking scattered paper scraps and dust in real time;

[0037] At the same time, the linkage negative pressure mechanism 22 includes a piston plate 23, a piston rod 24 and a sealing plate assembly. The piston plate 23 is slidably arranged in the adsorption box 8. One end of the piston rod 24 is fixed to the piston plate 23, and the other end penetrates through the top of the adsorption box 8 and is fixedly connected to the cutting seat 6; the sealing plate assembly includes a first sealing plate 25 hinged to the inner groove of the air suction port of the communication box 10 and a second sealing plate 26 hinged to the outside of the air outlet of the communication box 10. When the piston plate 23 moves up and down with the cutting seat 6, it adsorbs the paper scraps and dust generated by cutting through negative pressure and transports them to the waste paper recycling device through the exhaust pipe 13; when the cutting seat 6 moves up, the piston plate 23 generates negative pressure and opens the first sealing plate 25 to adsorb paper scraps; when it moves down, the second sealing plate 26 opens, and the waste materials are centrally discharged through the exhaust pipe 13, realizing synchronous operation of cutting and recycling; the waste materials are directionally recycled through a closed pipeline, reducing dust pollution in the workshop. The recycled paper scraps can be directly used for the production of recycled paper, reducing raw material waste;

[0038] It should be noted that the air suction port of the air suction head 12 faces the cutting position of the cutting knife 7, and the air suction head 12 and the communication box 10 are fixedly connected to the fixing plate 30 together. The air suction port of the air suction head 12 directly aims at the cutting area, improving the adsorption efficiency and reducing paper scrap residue; the air suction head 12 and the communication box 10 are integrally connected to the fixing plate 30, so that the air suction head 12 can be adjusted up and down together with the auxiliary frame 18 under the action of the second drive box 17, ensuring that the air suction port of the air suction head 12 is in close contact with the corrugated paper, thereby improving the adsorption efficiency of the paper scraps generated when the cutting knife 7 cuts.

[0039] In this technical solution, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5, the adjusting device 14 includes a pressure roller 15 and an adjusting frame 16. The adjusting frame 16 is symmetrically arranged on both sides of the cutting frame 4 and at the feeding end of the roller conveyor line 2. A second driving box 17 is fixedly provided at the top of the adjusting frame 16. An auxiliary frame 18 is installed at the output end of the second driving box 17. A pressure roller 15 is rotatably arranged inside the auxiliary frame 18. The pressure roller 15 is vertically corresponding to the rollers of the roller conveyor line 2 and is used to stably press the corrugated paper onto the cutting table 3; the height of the pressure roller 15 is adjusted by the second driving box 17 to adapt to corrugated paper of different thicknesses, ensuring the flatness of the paper during transportation; the rotation speed of the pressure roller 15 is synchronized with that of the roller conveyor line 2 to avoid paper slipping or offsetting and reduce cutting misalignment; the modular design of the adjusting frame 16 and the auxiliary frame 18 supports quick adjustment, adapts to the processing requirements of corrugated paper of various specifications, and improves the versatility of the equipment;

[0040] Meanwhile, evenly distributed electric push rods 27 are symmetrically and fixedly arranged inside the support frame 1. A pressing frame 28 is fixedly installed at the output end of the electric push rod 27. An auxiliary roller 29 is rotatably arranged inside the pressing frame 28. The auxiliary roller 29 is used to adapt to corrugated paper of different widths; the distance between the pressing rollers 15 is adjusted by the electric push rods 27 to adapt to corrugated paper of different widths, improving the versatility of the equipment; the pressing rollers 15 cooperate with the roller conveyor line 2 to prevent paper offset and ensure the alignment of the cutting path.

[0041] In this technical solution, referring to Figure 2 , Figure 5 , Figure 8 and Figure 9 , the cleaning assembly 19 includes a cleaning block 20 and a spring guiding mechanism 21. A brush is fixedly provided at the bottom of the cleaning block 20. The brush of the cleaning block 20 is made of nylon. The nylon brush has strong wear resistance and a long service life, which can reduce the replacement frequency. The spring guiding mechanism 21 is arranged on both sides of the cutting frame 4 and is used to drive the cleaning block 20 to reciprocally remove dust from the surface of the corrugated paper before the cutter 7 cuts. The cleaning block 20 removes dust and impurities on the surface of the corrugated paper before cutting, avoiding foreign objects interfering with the path of the cutter 7 and ensuring neat cutting edges;

[0042] Among them, the compression spring guiding mechanism 21 includes a fixing plate 30, a slider 32 and a plurality of triangular guiding blocks 31. The fixing plate 30 is arranged on both sides of the roller conveyor line 2. Both ends of the fixing plate 30 are fixed to two auxiliary frames 18 located on both sides of the cutting frame 4. The slider 32 is slidably arranged in the sliding opening of the fixing plate 30. Both ends of the cleaning block 20 are fixed to the slider 32. A pressure rod 33 is fixedly arranged on the outside of the cutting seat 6. The pressure rod 33 penetrates through the through hole of the cutting table 3 and is slidably connected to the through hole through a slide rail and chute structure. The triangular guiding blocks 31 are fixedly arranged on the outside of the pressure rod 33 in an array. The triangular guiding blocks 31 are located below the cutting knife 7. A fixing rod 34 is fixedly arranged between the two sliders 32. The outer end of the fixing rod 34 contacts the triangular guiding block 31. The cleaning block 20 is driven to reciprocate by the downward pressure of the cutting seat 6. When the cutting seat 6 presses down, the triangular guiding block 31 drives the slider 32 to drive the cleaning block 20 to reciprocate, removing the surface dust and improving the cutting quality. A strengthening block 39 is fixedly arranged between the pressure rod 33 and the cutting seat 6 to reduce the bending stress at the connection between the pressure rod 33 and the cutting seat 6.

[0043] In addition, a sliding frame 35 is arranged on the top of the fixing plate 30. A sliding rod 36 and a compression spring 37 are fixedly arranged in the sliding frame 35. The sliding rod 36 penetrates through the slider 32 and is slidably connected to the slider 32. One end of the compression spring 37 is fixed to the sliding frame 35, and the other end is fixed to the slider 32, which is used to reset the cleaning block 20. After the cleaning block 20 is reset by the compression spring 37, it is located outside the cutting path of the cutting knife 7 to avoid interference with the cutting knife 7. The compression spring 37 provides a reset force to quickly return the cleaning block 20 to its original position and improve the dust removal efficiency.

[0044] It should be noted that the elastic threaded box 9 can adapt to the stretching effect generated when the suction head 12 and the communication box 10 move up and down with the auxiliary frame 18.

[0045] The implementation process of this technical solution is as follows:

[0046] S1. Drive the auxiliary roller 29 to move towards the middle of the support frame 1 through the electric push rod 27, and adjust the distance between the symmetrically distributed auxiliary rollers 29 to adapt to the width of the corrugated paper to be cut.

[0047] S2. Drive the auxiliary frame 18 to move up and down through the second drive box 17, and adjust the height of the pressure roller 15 to ensure that the clearance height between the pressure roller 15 and the roller conveyor line 2 is adapted to the thickness of the corrugated paper to be cut.

[0048] S3. Start the roller conveyor line 2. At the same time, drive the pressure roller 15 to rotate through the adjustment motor 38, synchronize the rotation speed of the pressure roller 15 with the conveying speed of the roller conveyor line 2, and use the roller conveyor line 2 to convey the corrugated paper to be cut to the cutting table 3.

[0049] S4. Drive the cutting seat 6 to move downward through the first drive box 5, thereby driving the cutting knife 7 to move downward. During the downward movement of the cutting seat 6, the pressing rod 33 continuously moves downward in the through hole. During this process, the fixed rod 34 moves back and forth under the guidance of the triangular guide block 31 and the action of the compression spring 37, thereby driving the slider 32 and the cleaning block 20 to move back and forth together under the cutting knife 7. The cleaning block 20 is used to clean the dust on the surface of the corrugated paper to be cut. After cleaning back and forth several times, the fixed rod 34 abuts against the upper end of the pressing rod 33 under the action of the compression spring 37, and there is no triangular guide block 31 at the upper end of the pressing rod 33, thereby preventing the cleaning block 20 from moving back and forth again and affecting the cutting of the cutting knife 7;

[0050] S5. The cutting knife 7 cuts the corrugated paper to be cut after being cleaned by the cleaning block 20, cuts the corrugated paper into a specified length, and transports it to the next process through the roller conveyor line 2;

[0051] S6. After the cutting knife 7 cuts, it moves upward and returns to its original position. During this process, the cutting seat 6 drives the piston rod 24 and the piston plate 23 to move upward together. The piston plate 23 forms a negative pressure in the adsorption box 8, thereby opening the first sealing plate 25 at the air inlet of the communication box 10, and sucking the paper scraps generated after the cutting knife 7 cuts and the dust generated by the cleaning block 20 moving back and forth into the communication box 10 together. During the next downward movement of the cutting knife 7, the cutting seat 6 drives the piston plate 23 to move downward, and the second sealing plate 26 opens under the gradually increasing air pressure, while the first sealing plate 25 is in a closed state, thereby pushing the air in the communication box 10 and the collected paper scraps into the exhaust pipe 13 together. The paper scraps entering the exhaust pipe 13 reach the waste paper recycling device through the exhaust pipe 13 for recycling and treatment.

[0052] Embodiment 2: This embodiment further describes Embodiment 1. As Figure 5 shown, the difference lies in the optimization of the pressure roller 15;

[0053] Specifically, the rotation speed of the pressure roller 15 is synchronized with the conveying speed of the roller conveyor line 2. The pressure roller 15 is driven by an adjustment motor 38, and the adjustment motor 38 is fixedly arranged outside the auxiliary frame 18. The synchronous rotation speed eliminates the speed difference, avoids wrinkles or tears of the corrugated paper, and ensures continuous production.

[0054] Embodiment 3: This embodiment further describes Embodiment 1. As Figure 7 shown, the difference lies in the optimization of the internal structure of the communication box 10;

[0055] Specifically, an inclined diversion surface 40 that gradually decreases towards the air outlet along the long axis direction of the communication box 10 is provided inside the communication box 10. The lowest end of the inclined diversion surface 40 is directly communicated with the air outlet of the communication box 10, and is used to guide the adsorbed paper scraps and dust to gather towards the air outlet;

[0056] The inclined diversion surface 40 gradually descends towards the air outlet along the long axis direction of the connection box 10. By utilizing the synergistic effect of gravity and air flow, it guides the paper scraps and dust to naturally slide towards the air outlet, forming a concentrated flow path for the waste materials and preventing them from accumulating disorderly inside the box. Thus, through directional diversion, the paper scraps are quickly gathered at the air outlet. At the same time, the inclined diversion surface 40 cooperates with the negative pressure adsorption system inside the connection box 10 to form a double driving force of "air flow + gravity", which can reduce the residue of suspended particles.

[0057] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

7. The renewable ultra-low weight high-strength corrugated paper manufacturing device according to claim 1, characterized in that: The brush bristles of the cleaning block (20) are made of nylon.

8. The renewable ultra-low weight high-strength corrugated paper manufacturing device according to claim 3, characterized in that: A strengthening block (39) is fixedly provided between the pressure rod (33) and the cutting seat (6).

9. The renewable ultra-low weight high-strength corrugated paper manufacturing device according to claim 1, characterized in that: An inclined guide surface (40) is provided inside the connecting box (10) and gradually descends toward the air outlet along the long axis direction of the connecting box (10); the lowest end of the inclined guide surface (40) is directly connected to the air outlet of the connecting box (10) and is used to guide adsorbed paper scraps and dust to gather toward the air outlet.

10. A manufacturing process using the device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1, driving the auxiliary rollers (29) to move toward the middle of the support frame (1) by the electric push rod (27), and adjusting the spacing between the symmetrically distributed auxiliary rollers (29) to adapt to the width of the corrugated paper to be cut; S2, driving the auxiliary frame (18) to move up and down through the second driving box (17), adjusting the height of the pressing roller (15), and ensuring that the height of the gap between the pressing roller (15) and the roller conveyor line (2) is adapted to the thickness of the corrugated paper to be cut; S3, starting the roller conveyor line (2), and at the same time, driving the pressing roller (15) to rotate through the regulating motor (38), synchronizing the rotation speed of the pressing roller (15) with the conveying speed of the roller conveyor line (2), and using the roller conveyor line (2) to convey the corrugated paper to be cut to the cutting table (3); S4, the cutting seat (6) is driven to move downward by the first driving box (5), thereby driving the cutter (7) to move downward. During the downward movement of the cutting seat (6), the pressure rod (33) continuously moves downward in the through hole. During this process, the fixed rod (34) moves back and forth under the guidance of the triangular guide block (31) and the action of the compression spring (37), thereby driving the slider (32) and the cleaning block (20) to move back and forth under the cutter (7) through the fixed rod (34). The cleaning block (20) is used to clean the dust on the surface of the corrugated paper to be cut. After cleaning back and forth several times, the fixed rod (34) is pressed against the upper end of the pressure rod (33) under the action of the compression spring (37), and the upper end of the pressure rod (33) does not have the triangular guide block (31), thereby preventing the cleaning block (20) from moving back and forth again to affect the cutting of the cutter (7); S5, the cutter (7) cuts the corrugated paper to be cut after being cleaned by the cleaning block (20), cuts the corrugated paper into a specified length, and transports it to the next process through the roller conveyor line (2); S6. After cutting, the cutter (7) moves upward and returns to its original position. During this process, the cutting seat (6) drives the piston rod (24) and the piston plate (23) to move upward together. The piston plate (23) forms a negative pressure in the adsorption box (8), thereby opening the first sealing plate (25) at the air inlet of the connecting box (10), and sucking the paper scraps generated after the cutting of the cutter (7) and the dust generated by the back and forth cleaning of the cleaning block (20) into the connecting box (10). During the next downward movement of the cutter (7), the cutting seat (6) drives the piston plate (23) to move downward, and the second sealing plate (26) opens under the gradually increasing air pressure, while the first sealing plate (25) is in a closed state, thereby connecting the air in the connecting box (10) and pushing the collected paper scraps into the exhaust pipe (13). The paper scraps entering the exhaust pipe (13) pass through the exhaust pipe (13) to the waste paper recycling device for recycling.
