DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand: the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figures 1 to 9As shown, the present invention provides a technical solution: a cardboard shredder, comprising a workbench 1, a support frame 2 is fixedly connected to the top of the workbench 1, a shredding box 3 is fixedly connected to the top of the support frame 2, two opposing pressure rollers 4 are rotatably connected to the inside of the shredding box 3, a plurality of shredding blocks 5 are fixedly connected to the outer walls of the two opposing pressure rollers 4, a lower hopper 6 is fixedly connected to the top of the shredding box 3, a transmission mechanism is arranged at the bottom of the shredding box 3, the transmission mechanism is used to screen the debris into fragments and pulp during transportation, a separation component is arranged at the bottom of the transmission component, the separation component is used to separate the pulp from the dust, a vibration component is arranged between the transmission component and the separation component, the vibration component is used to improve the screening and separation effects.

[0033] During operation: after the existing cardboard is crushed, cardboard scraps and pulp will be obtained. The pulp obtained after the cardboard is crushed needs to be screened and collected for reprocessing to make new paper. The volume of the cardboard scraps after crushing is much larger than the pulp, and they can be screened and separated through the filter plate. However, since a large amount of debris will accumulate on the filter plate, the filter plate will be blocked, thereby reducing the filtration efficiency and failing to completely screen and collect the cardboard scraps and pulp. Through the embodiment of this scheme, during specific use, the crushing box 3 is first fixed to the top of the workbench 1 through the support frame 2, and then the cardboard to be crushed is put into the opening of the lower bin 6, and the cardboard will enter the crushing box 3, and through the restriction of the lower bin 6, the thin surface of the cardboard will accurately fall into the crushing port formed by the two opposing pressure rollers 4, and the paper will be crushed through the continuous extrusion of the crushing block 5. The board is crushed, and the crushed debris will enter the transmission component, which will continuously transport the debris to avoid accumulation, which will cause the cardboard fragments and pulp in the debris to be unable to be fully screened. In the process of debris transmission, the cardboard fragments and pulp will be screened and separated, and the pulp can be further separated from the dust after screening to obtain pulp with higher purity. In the process of screening the cardboard fragments and pulp and separating the pulp from the dust, the vibration component will continuously stimulate the two screening and separation processes, so that it will remain active on the sieve holes during the separation process, effectively disperse and diffuse the debris, prevent adhesion and accumulation, thereby maintaining screening efficiency and smoothness. Through the above embodiment, the transmission mechanism allows the crushed debris to be screened during transportation, which can keep the screening process unobstructed and ensure the continuity and efficiency of the pulp preparation process.

[0034] like Figures 2 to 3 As shown, a baffle plate 9 is symmetrically fixedly connected to the bottom of the crushing box 3, and the transmission component includes a conveyor belt 7, which is located directly below the bottom opening of the crushing box 3. A plurality of screening holes 8 are provided on the inner wall of the surface of the conveyor belt 7, and a conveyor component 14 is provided on one side of the conveyor belt 7. The conveyor component 14 is used to enable the conveyor belt 7 to continuously transmit so as to achieve the effect of transporting debris.

[0035] During operation: after the cardboard enters the crushing box 3 for crushing, the debris will fall onto the upper surface of the conveyor belt 7, and through the restriction of the two shielding plates 9, the debris can accurately fall onto the upper surface of the conveyor belt 7 and will not be dispersed into the air to cause environmental pollution. Then the transport component 14 is started to transport the debris that falls on the conveyor belt 7 to avoid accumulation. During the transportation process, the pulp will flow out from the bottom of the conveyor belt 7 through the screening hole 8, and the fragments will continue to be transported on the conveyor belt 7.

[0036] like Figures 7 and 8 As shown, the separation assembly includes two multi-fold plates 26, and a plurality of screening holes 28 are opened on the inner wall of one side of the two multi-fold plates 26. The two multi-fold plates 26 are respectively located directly below the conveyor belt 7. Measuring plates 27 are provided on both sides of the two multi-fold plates 26, and the plurality of measuring plates 27 are fixedly installed on the top of the workbench 1.

[0037] During operation: after the pulp and cardboard fragments are screened, the pulp will flow from the bottom of the conveyor belt 7 to the upper surface of the multi-folding plate 26. Since the surface of the multi-folding plate 26 is continuously inclined, the pulp will flow continuously on the surface of the multi-folding plate 26. During the flow, the pulp and the dust contained therein will be separated through the screening hole 28 to obtain pulp with higher purity. The separated pulp will flow out from the bottom side of the multi-folding plate 26, and the dust will flow out from below the screening hole 28.

[0038] like Figures 7 and 8 As shown, the vibration assembly includes two groups of elliptical blocks 24, each group of elliptical blocks 24 is respectively located between the bottom of the conveyor belt 7 and the top of one of the multi-fold plates 26, one side of each elliptical block 24 is fixedly connected to a rotating rod 23, one side of the rotating rod 23 is fixedly connected to a transmission ring four 22, the outer wall of each rotating rod 23 is rotatably connected to a clamping member two 25, each clamping member two 25 is respectively fixedly installed on the outer wall of the baffle plate 9, and a transmission assembly is arranged on the outer side of the transmission ring four 22, and the transmission assembly is used to drive multiple transmission rings four 22 to rotate simultaneously.

[0039] During operation: when crushing is carried out, the two pressing rollers 4 will rotate relative to each other. When the two pressing rollers 4 rotate, they will drive the multiple transmission rings 4 22 to rotate through the transmission assembly. The transmission ring 4 22 will drive the elliptical block 24 to rotate through the rotating rod 23. The position of the elliptical block 24 is fixed by the clamping member 25. When the elliptical block 24 rotates, its outer wall will hit the bottom of the conveyor belt 7 and the top of the multi-folding plate 26 at the same time. Since the conveyor belt 7 has a certain toughness, it will vibrate when hit and can automatically reset. Therefore, through the above embodiment, when the elliptical block 24 hits the conveyor belt 7 and the multi-folding plate 26, the conveyor belt 7 and the multi-folding plate 26 will vibrate to a certain extent, so that the effect of screening cardboard fragments and pulp and separating pulp from dust is better, and the debris can be effectively dispersed and diffused to prevent adhesion and accumulation, thereby maintaining screening efficiency and smoothness.

[0040] like Figure 6 to Figure 7 As shown, the outer walls of the shafts of the two pressure rollers 4 are fixedly connected with gears 16, and the two gears 16 are meshed with each other. A motor 15 is fixedly connected to one side of the support frame 2, and the output shaft of the motor 15 is fixedly connected to one of the gears 16. The transmission assembly includes two transmission rings three 20, and the two transmission rings three 20 are respectively fixedly installed on the shafts of one of the pressure rollers 4. A transmission belt two 21 is connected between each transmission ring three 20 and the other two transmission rings four 22.

[0041] During operation: when crushing is required, the motor 15 is started, and its output shaft will drive one of the pairs of pressure rollers 4 to rotate, and through the mutual engagement of the two gears 16, the two pairs of pressure rollers 4 are made to rotate relative to each other to achieve the crushing effect. When the pairs of pressure rollers 4 are rotated, the two transmission rings three 20 are driven to rotate, and the two transmission rings three 20 drive multiple transmission rings four 22 to rotate simultaneously through two transmission belts two 21, thereby driving the elliptical block 24 to rotate, achieving the effect of impacting the conveyor belt 7 and the multi-folding plate 26.

[0042] like Figures 8 to 9 As shown, the bottom of each multi-fold plate 26 is fixedly connected with a connecting rod 29, both ends of each connecting rod 29 are fixedly connected with an inner slider 30, the outer wall of each inner slider 30 is slidably connected with a mounting slide 31, each mounting slide 31 is respectively fixedly installed on the outer wall of the measuring plate 27, and a return spring 32 is fixedly connected between the bottom of each connecting rod 29 and the inner bottom surface of the mounting slide 31.

[0043] During operation: when the multi-fold plate 26 is hit by the elliptical block 24, the inner sliders 30 on both sides will slide in the inner wall of the mounting slide 31 and will squeeze the return spring 32 downward; when the elliptical block 24 does not hit the multi-fold plate 26, the return spring 32 will reset the inner slider 30, so that the multi-fold plate 26 returns to its original position again, thus performing a continuous vibration process to achieve the vibration effect.

[0044] like Figures 5 and 6 As shown, a wind shaft 10 is symmetrically rotatably connected between the two shielding plates 9, a plurality of fan blades 11 are fixedly connected to the outer walls of the two wind shafts 10, the two wind shafts 10 are located directly above the conveyor belt 7, and a protective shell 12 is provided on the outer side of the two wind shafts 10. Clamping parts 13 are fixedly connected to the two sides of the two protective shells 12, and the clamping parts 13 are fixedly installed on the top of the shielding plates 9.

[0045] During operation: when the pressure roller 4 is rotated, the two wind shafts 10 will be driven to rotate. When the two wind shafts 10 are rotated, the fan blades 11 will generate wind in the transport direction just above the conveyor belt 7, which can not only dissipate the heat and cool down the debris that has just been crushed, but the air flow generated by the fan blades 11 can help prevent the debris from accumulating or adhering to the surface of the conveyor belt 7 during transportation.

[0046] like Figures 5 and 6 As shown, one end of the two wind shafts 10 is fixedly connected to a transmission ring 2 18, one of the shafts of the pressure roller 4 is fixedly connected to a transmission ring 17, and a transmission belt 19 is connected between the transmission ring 17 and the outer walls of the two transmission rings 2 18.

[0047] During operation: When the crushing process is in progress, the rotation of the pressing roller 4 will drive the transmission ring 1 17 to rotate, and drive the two transmission rings 2 18 to rotate through the transmission belt 1 19. When the two transmission rings 2 18 rotate, the fan blades 11 are driven to rotate, achieving the effect of generating wind force directly above the conveyor belt 7.

[0048] like Figure 1 to Figure 2 As shown, a collecting box 3 36 is provided on the top of the workbench 1 , and a scraper table 35 is fixedly connected to the top of the collecting box 36 , and the top of the scraper table 35 is in contact with the upper surface of the conveyor belt 7 .

[0049] During operation: after the screening hole 8 screens the cardboard fragments and pulp, the cardboard fragments will be transported to one end through the conveyor belt 7, detached from the upper surface of the conveyor belt 7 and collected, and some fragments adhering to the surface of the conveyor belt 7 can be scraped off by the scraper table 35 to avoid the situation where all of them cannot be collected.

[0050] like Figure 8As shown, a collecting box 1 33 is disposed below the outlets of the two multi-fold plates 26 , and a collecting box 2 34 is disposed below the outlets of the two screening holes 28 . The collecting box 1 33 and the collecting box 2 34 are both disposed on the top of the workbench 1 .

[0051] During operation: after the pulp and dust are screened and separated, the pulp will eventually fall into the collecting box 1 33 along the upper surface of the multi-fold plate 26 for collection, while the dust will flow into the collecting box 2 34 through the bottom of the screening hole 28 for collection.

[0052] Working process: First, fix the crushing box 3 on the top of the workbench 1 through the support frame 2, and then put the cardboard to be crushed into the opening of the lower bin 6. The cardboard will enter the crushing box 3, and through the restriction of the lower bin 6, the thin surface of the cardboard will accurately fall into the crushing opening formed by the two pairs of pressure rollers 4. During the crushing process, start the motor 15, and its output shaft will drive one of the pairs of pressure rollers 4 to rotate, and through the mutual engagement of the two gears 16, the two pairs of pressure rollers 4 will rotate relatively to complete the crushing effect.

[0053] Secondly, after the cardboard enters the crushing box 3 and is crushed, the debris will fall onto the upper surface of the conveyor belt 7, and through the restriction of the two shielding plates 9, the debris can accurately fall onto the upper surface of the conveyor belt 7 and will not be dispersed into the air to cause environmental pollution. Then the transport component 14 is started to transport the debris that falls on the conveyor belt 7 to avoid accumulation. During the transportation process, the pulp will flow out from the bottom of the conveyor belt 7 through the screening hole 1 8, and the fragments will continue to be transported on the conveyor belt 7. After the pulp and cardboard fragments are screened, the pulp will flow from the bottom of the conveyor belt 7 to the upper surface of the multi-folding plate 26. Since the surface of the multi-folding plate 26 is continuously inclined, the pulp will flow continuously on the surface of the multi-folding plate 26. During the flow process, the pulp and the dust contained therein will be separated through the screening hole 28 to obtain pulp with higher purity. The separated pulp will flow out from the bottom side of the multi-folding plate 26, and the dust will flow out from below the screening hole 28.

[0054] When the two pressing rollers 4 rotate, the multiple transmission rings 4 22 will be driven to rotate through the transmission assembly. The transmission ring 4 22 will drive the elliptical block 24 to rotate through the rotating rod 23. The position of the elliptical block 24 is fixed by the clamping member 25. When the elliptical block 24 rotates, its outer wall will hit the bottom of the conveyor belt 7 and the top of the multi-folding plate 26 at the same time. Since the conveyor belt 7 has a certain toughness, it will vibrate when hit and can automatically reset. When the multi-folding plate 26 is hit by the elliptical block 24, it will slide in the inner wall of the mounting slide 31 through the inner sliders 30 on both sides and will squeeze the reset spring 32 downward. When the elliptical block 24 does not hit the multi-folding plate 26, the reset spring 32 will reset the inner slider 30, so that the multi-folding plate 26 returns to its original position again. In this way, a continuous vibration process is carried out to achieve a vibration effect.

[0055] During the crushing process, the rotation of the pressure roller 4 will drive the transmission ring 17 to rotate, and drive the two transmission rings 18 to rotate through the transmission belt 19. When the two transmission rings 18 rotate, they will drive the two wind shafts 10 to rotate. When the two wind shafts 10 rotate, the fan blades 11 will generate wind force in the transport direction just above the conveyor belt 7, which can not only dissipate the heat and cool down the debris that has just been crushed, but the air flow generated by the fan blades 11 can help prevent the debris from accumulating or adhering to the surface of the conveyor belt 7 during transportation.

[0056] Finally, after the screening hole 8 screens the cardboard fragments and pulp, the cardboard fragments will be transported to one end through the conveyor belt 7, detached from the upper surface of the conveyor belt 7 and collected, and some fragments adhering to the surface of the conveyor belt 7 can be scraped off by the scraper table 35. After the pulp and dust are screened and separated, the pulp will eventually fall into the collection box 1 33 along the upper surface of the multi-fold plate 26 for collection, while the dust will flow into the collection box 2 34 through the bottom of the screening hole 28 for collection.
