Description

Technical Field

[0001] This invention relates to the field of waste paper recycling technology, specifically to a waste paper recycling crushing device and method. Background Technology

[0002] Waste paper recycling and shredding equipment is a special device used to recycle waste paper raw materials. It can reprocess wastewater into usable pulp, making it easier to reuse resources.

[0003] Existing waste paper recycling and shredding devices, such as the shredding device for waste cardboard box recycling and processing disclosed in Chinese patent application CN116043589A, cannot remove metal impurities (staples) from the waste paper raw materials while shredding them. This results in the metal impurities being mixed in the pulp, affecting the subsequent processing of the pulp. Summary of the Invention

[0004] In order to overcome the above-mentioned technical problems, the purpose of this invention is to provide a waste paper recycling and shredding device and method to solve the problem that in the prior art, the waste paper recycling and shredding device cannot remove metal impurities from the waste paper raw materials while shredding them, resulting in the production of pulp containing metal impurities that affect subsequent pulp processing.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0007] As a further aspect of the present invention: the feeding and crushing mechanism includes a feeding hopper, a crushing groove is provided at the top of the feeding hopper, a crushing roller is provided inside the crushing groove, and a feeding mechanism is provided at the bottom of the feeding hopper.

[0008] As a further aspect of the present invention: the crushing roller includes a first rotating shaft and a second rotating shaft, and a first toothed roller and a second toothed roller are respectively nested on the sides of the first rotating shaft and the second rotating shaft.

[0009] As a further aspect of the present invention: the feeding mechanism includes a feeding hopper, the inside of which is provided with a feeding groove, an impurity collecting hopper is fixedly connected to the bottom surface of the feeding hopper, an annular conductor block is fixedly connected to the inner side of the impurity collecting hopper, and an impurity conveying pipe is fixedly connected to the bottom surface of the impurity collecting hopper.

[0010] As a further aspect of the present invention: the magnetic separation mechanism includes a main body, a magnetic separation disk is provided on one side of the main body, an air outlet duct is connected to the other side of the main body, a fan housing is fixedly connected to the end of the air outlet duct away from the main body, and an air inlet duct is fixedly connected to one side of the fan housing.

[0011] As a further aspect of the present invention: the magnetic separation disk includes a rotating ring, a plurality of electromagnetic blocks are fixedly connected to the inner side of the rotating ring, and air blowing grooves are opened between the plurality of electromagnetic blocks. The rotating ring fits into the inner cavity of the impurity collection hopper and can rotate freely within the inner cavity of the impurity collection hopper.

[0012] As a further aspect of the present invention: a rotating shaft is installed at the inner center of the rotating ring, a fixed gear is fixedly connected to the end of the rotating shaft away from the rotating ring, a first gear is meshed with the side of the fixed gear, and a second gear is fixedly connected to one side of the first gear.

[0013] As a further aspect of the present invention: the transmission mechanism includes a sun gear, a planetary gear meshing on the side of the sun gear, a transmission gear ring meshing on the outer side of the planetary gear, a driving gear meshing on the side of the transmission gear ring, a transmission gear meshing on the side of the driving gear, a driven gear meshing on the side of the transmission gear away from the driving gear, the driving gear and the driven gear being poweredly connected to the first rotating shaft and the second rotating shaft respectively, and the transmission gear ring meshing with the second gear.

[0014] As a further aspect of the present invention: a device base is provided at the bottom of the main body of the crushing device, a material collecting cylinder is fixedly connected to the top surface of the device base, and an arc-shaped baffle is fixedly connected to the top surface of the material collecting cylinder.

[0015] The second aspect specifically provides a waste paper recycling and shredding method, which is based on the aforementioned waste paper recycling and shredding device and includes:

[0016] S1: Feed waste paper raw materials into the feeding and crushing mechanism;

[0017] S2: Turn on the drive motor via the control panel. The drive motor drives the feeding and crushing mechanism and the magnetic separation mechanism through the transmission mechanism.

[0018] S3: The feeding and crushing mechanism crushes the waste paper raw material, turning it into shredded paper.

[0019] S4: The magnetic separation mechanism blows the shredded paper while simultaneously using magnetic force to attract and remove metal impurities from the shredded paper.

[0020] S5: The separated paper scraps are recovered through the main body of the shredding device.

[0021] The beneficial effects of this invention are:

[0022] 1. In this invention, through the magnetic separation mechanism, after the waste paper raw material is put into the feeding and crushing mechanism, the drive motor is turned on. The drive motor will simultaneously transmit power to the magnetic separation mechanism and the feeding and crushing mechanism. The feeding and crushing mechanism can crush the waste paper raw material that enters it. After the feeding and crushing mechanism crushes the waste paper raw material into paper scraps, the paper scraps will be at the bottom of the feeding and crushing mechanism due to their own gravity. The magnetic separation mechanism uses magnetic force to attract metal impurities. After the impurity collection hopper collects the metal impurities, it is then transported to the external environment through the impurity conveying pipe, so that the metal impurities in the paper scraps can be automatically separated from the paper scraps, ensuring that the recycled paper scraps do not contain metal impurities, thus not affecting the subsequent processing of the paper scraps.

[0023] 2. In this invention, the output shaft of the drive motor is directly and fixedly connected to the impeller in the fan housing. When the drive motor is turned on, its power is transmitted to the impeller in the fan housing via the output shaft, causing the impeller to rotate at high speed. The high-speed rotation of the impeller generates centrifugal force on the air in the fan housing. It is important to note that the end of the air inlet pipe furthest from the fan housing extends outside the main body of the pulverizing device. This allows the air inlet pipe to draw in air from the external environment of the pulverizing device, which then enters the fan housing. The impeller in the fan housing, through centrifugal force, then transports the air through the outlet pipe to the interior of the main body of the mechanism. An internal conveying channel is provided inside the main body of the mechanism, through which air enters the magnetic separation disc. Finally, the air is output from the magnetic separation disc, which blows away the shredded paper, diverting the shredded paper and preventing it from entering the impurity collection hopper.

[0024] 3. In this invention, when the electromagnetic block comes into contact with the annular conductor block, the annular conductor block will transmit electrical energy to the electromagnetic block, causing the electromagnetic block to generate magnetic force. In this way, when the shredded paper passes through the magnetic separation disk, the magnetic force generated by the electromagnetic block can attract the metal impurities contained therein. Furthermore, since the magnetic separation disk can blow out air, it can prevent the shredded paper from approaching the electromagnetic block, and also prevent the shredded paper from getting stuck between the metal impurities and the electromagnetic block.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] like Figures 1-9 As shown, this invention discloses a waste paper recycling and shredding device, including a shredding device body 1. A feeding shredding mechanism 2 is provided at the top of the shredding device body 1, which is used to shred waste paper raw materials into paper scraps. A control console 3 is provided on one side of the shredding device body 1, and a transmission mechanism 5 is provided on the other side of the shredding device body 1. A drive motor 4 is installed on the outside of the transmission mechanism 5, which drives the feeding shredding mechanism 2. A magnetic separation mechanism 6 is provided at the bottom of the feeding shredding mechanism 2. The magnetic separation mechanism 6 uses magnetic force to attract metal impurities while the paper scraps are blown by the transmission mechanism 5. It should be noted that when recycling waste paper raw materials through this waste paper recycling shredding device... Waste paper raw materials can be fed into the main body 1 of the crushing device through the feeding crushing mechanism 2. Then, the drive motor 4 is turned on through the control panel 3. The power of the drive motor 4 can be transmitted to the feeding crushing mechanism 2 through the transmission mechanism 5, so that the feeding crushing mechanism 2 can crush the waste paper raw materials that enter it. After the feeding crushing mechanism 2 crushes the waste paper raw materials into paper scraps, the paper scraps will be at the bottom of the feeding crushing mechanism 2 due to their own gravity. At the same time, the power of the drive motor 4 can be transmitted to the magnetic separation mechanism 6. The magnetic separation mechanism 6 can separate the paper scraps at the bottom of the feeding crushing mechanism 2, so that the metal impurities are automatically removed, which helps the subsequent pulping process of the paper scraps.

[0040] like Figure 2 As shown, the feeding and crushing mechanism 2 includes a feeding hopper 21, a crushing groove 22 is provided at the top of the feeding hopper 21, a crushing roller 23 is provided inside the crushing groove 22, a feeding mechanism 25 is provided at the bottom of the feeding hopper 21, and a support rod 24 is provided on the outside of the feeding hopper 21. The support rod 24 is fixedly connected to the inner wall of the crushing device body 1, so that the feeding hopper 21 is stable at the top of the crushing device body 1. It should be noted that the cross-sectional shape of the crushing groove 22 is an inverted trapezoid, and the crushing roller 23 is provided at the bottom of the crushing groove 22. In this way, after the waste paper raw material is put into the crushing groove 22, due to the shape of the crushing groove 22, the waste paper raw material can be transported to the top of the crushing roller 23, and the crushing roller 23 tears the waste paper raw material.

[0041] like Figure 3As shown, the crushing roller 23 includes a first rotating shaft 231 and a second rotating shaft 233. A first toothed roller 232 and a second toothed roller 234 are respectively nested on the sides of the first rotating shaft 231 and the second rotating shaft 233. It should be noted that the outer side of the first rotating shaft 231 is fixedly connected to the inner side of the first toothed roller 232, so that when the first rotating shaft 231 rotates, it can drive the first toothed roller 232 to rotate synchronously. The outer side of the second rotating shaft 233 is fixedly connected to the inner side of the second toothed roller 234, so that when the second rotating shaft 233 rotates, it can drive the second toothed roller 234 to rotate synchronously. Several crushing teeth are fixedly connected to the outer sides of the first toothed roller 232 and the second toothed roller 234. The crushing teeth on the sides of the first toothed roller 232 and the second toothed roller 234 are staggered. The whole assembly of the first toothed roller 232 and the second toothed roller 234 fits into the bottom of the crushing tank 22. In this way, the waste paper raw material entering the crushing tank 22 can be crushed by the first toothed roller 232 and the second toothed roller 234 to form shredded paper. It should also be noted that the first toothed roller 232 and the second toothed roller 234 rotate in the same direction. When the waste paper raw material enters the position between the first toothed roller 232 and the second toothed roller 234, the first toothed roller 232 and the second toothed roller 234 can tear the waste paper raw material by the crushing teeth on their sides to form shredded paper.

[0042] like Figure 5 As shown, the feeding mechanism 25 includes a feeding hopper 251, with a feeding trough 252 inside the feeding hopper 251. An impurity collecting hopper 253 is fixedly connected to the bottom surface of the feeding hopper 251, and an annular conductor block 254 is fixedly connected to the inner side of the impurity collecting hopper 253. An impurity conveying pipe 255 is fixedly connected to the bottom surface of the impurity collecting hopper 253. It should be noted that the top surface of the feeding hopper 251 matches the bottom surface of the crushing trough 22, allowing the shredded paper in the crushing trough 22 to directly enter the feeding hopper 251. Inside the feeding trough 252, the impurity collection hopper 253 is located on the bottom surface of the feeding trough 252 near the transmission mechanism 5. The impurity collection hopper 253 can collect the metal impurities that the magnetic separation mechanism 6 adsorbs by magnetic force. After the impurity collection hopper 253 collects the metal impurities, it is then transported to the external environment through the impurity conveying pipe 255, so that the metal impurities in the shredded paper can be automatically separated from the shredded paper, ensuring that the shredded paper in the recycling does not contain metal impurities, so as not to affect the subsequent processing of the shredded paper.

[0043] like Figure 7 and Figure 8As shown, the magnetic separation mechanism 6 includes a main body 61. A magnetic separation disk 62 is provided on one side of the main body 61, and an air outlet duct 65 is connected to the other side of the main body 61. A fan housing 63 is fixedly connected to the end of the air outlet duct 65 away from the main body 61. An air inlet duct 64 is fixedly connected to one side of the fan housing 63. It should be noted that the output shaft of the drive motor 4 is directly fixedly connected to the fan impeller in the fan housing 63. Thus, when the drive motor 4 is turned on, the power of the drive motor 4 can be transmitted to the fan impeller in the fan housing 63 through the output shaft, causing the fan impeller to rotate at high speed. The high-speed rotating fan impeller will cause the air in the fan housing 63 to rotate at high speed. The air generates centrifugal force. It should be noted that the end of the air inlet duct 64 away from the fan housing 63 extends outside the main body 1 of the pulverizing device. In this way, the air inlet duct 64 can draw in air through the external environment of the main body 1 of the pulverizing device and bring the air into the fan housing 63. The fan impeller in the fan housing 63 then uses centrifugal force to transport the air through the air outlet duct 65 to the interior of the main body 61 of the mechanism. A conveying channel is opened inside the main body 61 of the mechanism, through which the air can enter the magnetic separation disk 62. Finally, the air is output by the magnetic separation disk 62, which blows the shredded paper and diverts the shredded paper to prevent it from entering the impurity collection hopper 253.

[0044] like Figure 5 and Figure 8 As shown, the magnetic separation disk 62 includes a rotating ring 621. Several electromagnetic blocks 622 are fixedly connected to the inner side of the rotating ring 621. Air blowing grooves 623 are formed between the electromagnetic blocks 622. The rotating ring 621 fits into the inner cavity of the impurity collection hopper 253 and can rotate freely within the impurity collection hopper 253. It should be noted that an annular conductor block 254 is provided inside the impurity collection hopper 253 to transmit electrical energy to the electromagnetic blocks 622. Therefore, when the electromagnetic blocks 622 contact the annular conductor block 254, the annular conductor block 254 transmits electrical energy to the electromagnetic blocks 622, causing the electromagnetic blocks 622 to generate magnetic force. Thus, when shredded paper passes through the magnetic separation disk 62, the magnetic force generated by the electromagnetic blocks 622 can attract the metal impurities contained within. Furthermore, since the magnetic separation disk 62 can blow air, it prevents shredded paper from approaching the electromagnetic blocks 622 while also preventing shredded paper from getting stuck between the metal impurities and the electromagnetic blocks 622. Figure 5 and 7As shown, the annular conductor block 254 is located in the upper half of the magnetic separation disk 62. Therefore, the annular conductor block 254 can generate magnetic force on the electromagnetic block 622 corresponding to the upper half of the magnetic separation disk 62. When the magnetic separation disk 62 rotates in the impurity collection hopper 253, the upper half of the magnetic separation disk 62 is exposed. This ensures that the exposed part of the magnetic separation disk 62 is always in contact with the annular conductor block 254 when it rotates in the impurity collection hopper 253. The annular conductor block 254 can always transmit electrical energy to the electromagnetic block 622 on the magnetic separation disk 62, causing the electromagnetic block 622 to generate magnetic force. When the electromagnetic block 622 attracts... When the metal impurities rotate to the lower half of the magnetic separation disk 62, the electromagnetic block 622 will automatically disengage from the annular conductor block 254. As a result, the magnetic force of the electromagnetic block 622 will disappear, and the attraction force generated by the electromagnetic block 622 will also disappear. The metal impurities adsorbed on the electromagnetic block 622 will automatically fall to the bottom of the impurity collection hopper 253 and be discharged through the impurity conveying pipe 255. During the rotation of the electromagnetic block 622 in the impurity collection hopper 253, it can automatically adsorb metal impurities and automatically discharge the metal impurities into the impurity collection hopper 253, thus realizing the automatic separation of metal impurities in shredded paper.

[0045] like Figure 5 , Figure 7 and Figure 8 As shown, a rotating shaft 624 is installed at the inner center of the rotating ring 621. A fixed gear 625 is fixedly connected to one end of the rotating shaft 624 away from the rotating ring 621. A first gear 626 meshes with the side of the fixed gear 625. A second gear 627 is fixedly connected to one side of the first gear 626. A fixed bearing 628 is provided between the first gear 626 and the second gear 627. The fixed bearing 628 is fixed inside the main body 1 of the crushing device through a bearing seat. It should be noted that since the first gear 626 and the second gear 627 are fixedly connected, when the second gear 627 rotates, the second gear 627 will drive the first gear 626 to rotate synchronously. Since the fixed gear 625 is meshed with the first gear 626, the rotating first gear 626 will also drive the fixed gear 625. The fixed gear 625 then drives the rotating ring 621 to rotate through the rotating shaft 624, so that the rotating ring 621 can rotate stably inside the impurity collection hopper 253.

[0046] Since air blowing slots 623 are provided between the electromagnetic blocks 622, when the air blowing slots 623 rotate to correspond with the conveying channel inside the main body 61 of the mechanism, the conveying channel inside the main body 61 of the mechanism can deliver air to the air blowing slots 623, so that the air blowing slots 623 can blow out air. The air blowing slots 623 are evenly distributed in a ring shape on the inner side of the rotating ring 621. Therefore, no matter what state the rotating ring 621 rotates to, the inner side of the rotating ring 621 always has air blowing slots 623 rotating to correspond with the conveying channel inside the main body 61 of the mechanism, ensuring that the magnetic separation disk 62 always produces a blowing effect.

[0047] like Figure 6 As shown, the transmission mechanism 5 includes a sun gear 51, a planetary gear 53 meshing on the side of the sun gear 51, a transmission gear ring 54 meshing on the outer side of the planetary gear 53, a drive gear 55 meshing on the side of the transmission gear ring 54, a transmission gear 56 meshing on the side of the drive gear 55, and a driven gear 57 meshing on the side of the transmission gear 56 away from the drive gear 55. The drive gear 55 and the driven gear 57 are respectively poweredly connected to the first rotating shaft 231 and the second rotating shaft 233. The transmission gear ring 54 meshes with the second gear 627. It should be noted that the output shaft of the drive motor 4 is fixedly connected to the center of the sun gear 51, and the output shaft also passes through the sun gear 51 and is fixedly connected to the fan impeller inside the fan housing 63. Thus, when the drive motor is turned on... After the machine 4 is in operation, the drive motor 4 can simultaneously drive the sun gear 51 and the fan impeller inside the fan housing 63 to rotate. The outer side of the planetary gear 53 is equipped with a fixing ring 52 through a rotating shaft. The fixing ring 52 is fixed to the side of the main body 1 of the crushing device by bolts. In this way, when the sun gear 51 rotates, the sun gear 51 can drive the transmission gear ring 54 to rotate through the planetary gear 53. Since the side of the transmission gear ring 54 is meshed with the drive gear 55, the rotating transmission gear ring 54 can drive the drive gear 55 to rotate. The drive gear 55 meshes with the driven gear 57 through the transmission gear 56. Therefore, the rotating drive gear 55 can drive the driven gear 57 through the transmission gear 56, so that the driven gear 57 and the drive gear 55 rotate at the same speed and in the same direction.

[0048] The driving gear 55 and the driven gear 57 are fixedly connected to the first rotating shaft 231 and the second rotating shaft 233, respectively. When the driving gear 55 and the driven gear 57 rotate at the same speed and in the same direction, the first rotating shaft 231 and the second rotating shaft 233 can rotate at the same speed and in the same direction, which means that the first toothed roller 232 and the second toothed roller 234 can rotate at the same speed and in the same direction. When the waste paper material enters the position between the first toothed roller 232 and the second toothed roller 234, the first toothed roller 232 and the second toothed roller 234 can tear the waste paper material through the crushing teeth on their sides, so that the waste paper material is formed into shredded paper.

[0049] Since the transmission gear ring 54 meshes with the second gear 627, the rotation of the transmission gear ring 54 will also drive the second gear 627 to rotate. The second gear 627 will then drive the rotating ring 621 to rotate through the first gear 626, the fixed gear 625 and the rotating shaft 624. Therefore, through a drive motor 4 and a transmission mechanism 5, the feeding crushing mechanism 2 can simultaneously crush the waste paper raw materials and the magnetic separation mechanism 6 can automatically separate the metal impurities from the resulting shredded paper, ensuring that the shredded paper in the recycling process does not contain metal impurities, thus not affecting the subsequent processing of the shredded paper.

[0050] like Figures 1-9 As shown, a base 11 is provided at the bottom of the main body 1 of the shredding device. A collection cylinder 12 is fixedly connected to the top surface of the base 11, and an arc-shaped baffle 13 is fixedly connected to the top surface of the collection cylinder 12. It should be noted that the collection cylinder 12 is used to receive shredded paper, while the arc-shaped baffle 13 is located on one side of the magnetic separation mechanism 6. In this way, when the magnetic separation mechanism 6 blows the shredded paper, the arc-shaped baffle 13 can block the shredded paper and discharge the blocked shredded paper into the collection cylinder 12. The collection cylinder 12 can be connected to a pulper, so that the separated shredded paper... The paper scraps can be directly conveyed to the pulper through the collection cylinder 12, where they are pulped. The material transfer method between the collection cylinder 12 and the pulper can be adapted by those skilled in the art based on the spatial position between the collection cylinder 12 and the pulper. For example, when the collection cylinder 12 is at the top of the pulper, the paper scraps in the collection cylinder 12 can enter the pulper by free sliding. When the collection cylinder 12 is at the bottom of the pulper, the paper scraps in the collection cylinder 12 can enter the pulper through the conveyor belt.

[0051] Example 2

[0052] like Figures 1-10 As shown, this invention discloses a waste paper recycling and shredding method, comprising:

[0053] S1: Waste paper raw material is put into the feeding and crushing mechanism 2. The amount of waste paper raw material put in is adaptively selected by those skilled in the art based on the volume of the feeding and crushing mechanism 2.

[0054] S2: Turn on the drive motor 4 via the control console 3. The drive motor 4 drives the feeding crushing mechanism 2 and the magnetic separation mechanism 6 through the transmission mechanism 5. Specifically, the speed of the drive motor 4 is controlled by the control console 3. The speed of the drive motor 4 can be controlled according to the weight of the waste paper raw material entering the feeding crushing mechanism 2. Generally, the greater the weight of the waste paper raw material entering the feeding crushing mechanism 2, the faster the speed required by the drive motor 4 is to ensure that the feeding crushing mechanism 2 can process the waste paper raw material in time. The power of the drive motor 4 is transmitted to the sun gear 51 through the output shaft. The sun gear 51 can drive the transmission gear ring 54 to rotate through the planetary gear 53. The transmission gear ring 54 drives the drive gear 55 to rotate. The rotating drive gear 55 can drive the driven gear 57 through the transmission gear 56, so that the driven gear 57 rotates at the same speed and in the same direction as the drive gear 55. The drive gear 55 and the driven gear 57 are fixedly connected to the first rotating shaft 231 and the second rotating shaft 233 respectively. In this way, the drive gear 55 and the driven gear 57 rotate at the same speed and in the same direction.

[0055] S3: The feeding and crushing mechanism 2 crushes the waste paper raw material to form shredded paper. Specifically, when the driving gear 55 and the driven gear 57 rotate at the same speed and in the same direction, the first rotating shaft 231 and the second rotating shaft 233 can rotate at the same speed and in the same direction, which means that the first toothed roller 232 and the second toothed roller 234 rotate at the same speed and in the same direction. When the waste paper raw material enters the position between the first toothed roller 232 and the second toothed roller 234, the first toothed roller 232 and the second toothed roller 234 can tear the waste paper raw material through the crushing teeth on their sides to form shredded paper. The shredded paper in the crushing trough 22 can directly enter the feeding trough 252 inside the feeding hopper 251.

[0056] S4: The magnetic separation mechanism 6 blows the shredded paper while simultaneously attracting metal impurities from the shredded paper through magnetic force and automatically removes the metal impurities. Specifically, the transmission gear ring 54 drives the second gear 627, which in turn drives the first gear 626 to rotate synchronously. The rotating first gear 626 also drives the fixed gear 625, which in turn drives the rotating ring 621 to rotate through the rotating shaft 624. This causes the rotating ring 621 to rotate stably inside the impurity collection hopper 253. The power of the drive motor 4 can then be transmitted through the output shaft to the fan impeller in the fan housing 63, causing the fan impeller to rotate at high speed. The high-speed rotating fan impeller will generate centrifugal force in the air inside the fan housing 63. When the air blowing channel 623 rotates to correspond with the conveying channel inside the main body 61 of the mechanism, the conveying channel inside the main body 61 of the mechanism can then deliver air to the air blowing channel 623, allowing the air blowing channel 623 to blow out air and preventing shredded paper from entering the impurity collection hopper 253.

[0057] S5: The separated shredded paper is recovered through the main body 1 of the crushing device. When the shredded paper is blown by the magnetic separation mechanism 6, the arc-shaped baffle 13 can block the shredded paper and discharge the blocked shredded paper into the collection cylinder 12. The collection cylinder 12 is connected to the pulper. In this way, the separated shredded paper is directly transported to the pulper through the collection cylinder 12, and the pulper performs pulping treatment on the shredded paper.

[0058] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
