[0016] S1: Put waste paper raw materials into the feed shredding mechanism;

[0017] S2: Turn on the drive motor through the console, and the drive motor drives the feed crushing mechanism and the magnetic separation mechanism through the transmission mechanism;

[0018] S3: The feed shredding mechanism shreds the waste paper raw material into paper scraps;

[0019] S4: The magnetic separation mechanism blows away the paper scraps and simultaneously absorbs the metal debris in the paper scraps through magnetic force and automatically removes the metal debris;

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

[0021] Beneficial effects of the present invention:

[0022] 1. In the present invention, by setting up a magnetic separation mechanism, after the waste paper raw material is placed in the feed pulverizing mechanism, the driving motor is turned on, and the driving motor will simultaneously transmit power to the magnetic separation mechanism and the feed pulverizing mechanism, and the feed pulverizing mechanism can pulverize the waste paper raw material entering therein. After the feed pulverizing mechanism pulverizes the waste paper raw material into shredded paper, the shredded paper will be at the bottom of the feed pulverizing mechanism due to its own gravity, and the magnetic separation mechanism absorbs metal debris through magnetic force. After the impurity collection bucket collects the metal debris, it is transported to the external environment through the impurity conveying pipe, so that the metal debris in the shredded paper can be automatically separated from the shredded paper, ensuring that the shredded paper being recycled does not contain metal debris, so as not to affect the subsequent treatment of the shredded paper.

[0023] 2. In the present invention, the output shaft of the driving motor is directly fixedly connected to the fan impeller in the fan housing. In this way, after the driving motor is turned on, the power of the driving motor can be transmitted to the fan impeller in the fan housing through the output shaft, so that the fan impeller rotates at high speed. The high-speed rotating fan impeller will generate centrifugal force for the air in the fan housing. It should be noted that the end of the air inlet duct away from the fan housing extends out of the outside of the pulverizing device body. In this way, the air inlet duct can draw in air through the external environment of the pulverizing device body, so that the air enters the fan housing, and the fan impeller in the fan housing then uses the action of centrifugal force to transport the air to the interior of the mechanism body through the air outlet duct. A conveying channel is provided inside the mechanism body, and the air can enter the magnetic separation disk through the conveying channel and is finally output by the magnetic separation disk to blow the shredded paper, divert the shredded paper, and prevent the shredded paper from entering the impurity collection bucket.

[0024] 3. In the present invention, when the electromagnetic block contacts the annular conductor block, the annular conductor block transmits electrical energy to the electromagnetic block, causing the electromagnetic block to generate magnetic force. In this way, when the paper scraps pass through the magnetic separation disk, the magnetic force generated by the electromagnetic block can absorb the metal debris contained therein. Moreover, since the magnetic separation disk can blow out air, it can prevent the paper scraps from approaching the electromagnetic block while also preventing the paper scraps from being sandwiched between the metal debris and the electromagnetic block.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] Example 1

[0039] like Figures 1-9 As shown, the present invention discloses a waste paper recycling and shredding device, comprising a shredding device body 1, a feeding shredding mechanism 2 is arranged on the top of the shredding device body 1, which is used to shred waste paper raw materials to form shredded paper scraps. A control console 3 is arranged on one side of the shredding device body 1, and a transmission mechanism 5 is arranged on the other side of the shredding device body 1. A driving motor 4 is installed on the outer side of the transmission mechanism 5, and the transmission mechanism 5 is used to drive the feeding shredding mechanism 2. A magnetic separation mechanism 6 is arranged at the bottom of the feeding shredding mechanism 2. The magnetic separation mechanism 6 is based on the transmission mechanism 5. The shredding paper scraps are blown by the transmission mechanism 5 while the metal debris is absorbed by the magnetic force. It should be noted that when the waste paper raw materials are recycled by the waste paper recycling and shredding device, The waste paper raw material can be put into the pulverizing device main body 1 through the feeding pulverizing mechanism 2, and then the driving motor 4 can be turned on through the control console 3. The power of the driving motor 4 can be transmitted to the feeding pulverizing mechanism 2 through the transmission mechanism 5, so that the feeding pulverizing mechanism 2 can pulverize the waste paper raw material entering therein. After the feeding pulverizing mechanism 2 pulverizes the waste paper raw material into shredded paper, the shredded paper will be at the bottom of the feeding pulverizing mechanism 2 due to its own gravity, and the power of the driving motor 4 can be transmitted to the magnetic separation mechanism 6 at the same time. The magnetic separation mechanism 6 can separate the shredded paper at the bottom of the feeding pulverizing mechanism 2, so that the metal debris therein is automatically removed, which is conducive to the subsequent pulping process of the shredded paper.

[0040] like Figure 2 As shown, the feeding and crushing mechanism 2 includes a feeding hopper 21, a crushing trough 22 is provided on the top of the feeding hopper 21, a crushing roller 23 is provided inside the crushing trough 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 stabilized on the top of the crushing device body 1. It should be noted that the cross-section of the crushing trough 22 is an inverted trapezoid, and the crushing roller 23 is provided at the bottom of the crushing trough 22. In this way, after the waste paper raw material is put into the crushing trough 22, due to the shape of the crushing trough 22, the waste paper raw material can be transported to the top of the crushing roller 23, and the waste paper raw material is torn by the crushing roller 23.

[0041] like Figure 3As shown, the crushing roller 23 includes a first rotating shaft 231 and a second rotating shaft 233. The sides of the first rotating shaft 231 and the second rotating shaft 233 are respectively embedded with a first tooth roller 232 and a second tooth roller 234. It should be noted that the outer side surface of the first rotating shaft 231 is fixedly connected to the inner side surface of the first tooth roller 232, so that when the first rotating shaft 231 rotates, it can drive the first tooth roller 232 to rotate synchronously, and the outer side surface of the second rotating shaft 233 is fixedly connected to the inner side surface of the second tooth roller 234, so that when the second rotating shaft 233 rotates, it can drive the second tooth roller 234 to rotate synchronously. The outer sides of the first tooth roller 232 and the second tooth roller 234 are fixedly connected with a plurality of crushing teeth. The first tooth roller 231 and the second tooth roller 234 are respectively embedded with a first tooth roller 232 and a second tooth roller 234. The crushing teeth on the sides of the first tooth roller 232 and the second tooth roller 234 are staggered with each other, and the whole formed by the first tooth roller 232 and the second tooth roller 234 fits with the bottom of the crushing trough 22, so that the waste paper raw materials entering the crushing trough 22 can be crushed by the first tooth roller 232 and the second tooth roller 234, so that the waste paper raw materials are formed into shredded paper scraps. It should also be noted that the rotation directions of the first tooth roller 232 and the second tooth roller 234 are the same, so that when the waste paper raw materials enter the position between the first tooth roller 232 and the second tooth roller 234, the first tooth roller 232 and the second tooth roller 234 can tear the waste paper raw materials through the crushing teeth on their sides, so that the waste paper raw materials are formed into shredded paper scraps.

[0042] like Figure 5 As shown, the unloading mechanism 25 includes a unloading hopper 251, a unloading trough 252 is provided inside the unloading hopper 251, an impurity receiving hopper 253 is fixedly connected to the bottom surface of the unloading hopper 251, an annular conductor block 254 is fixedly connected to the inner side of the impurity receiving hopper 253, and an impurity conveying pipe 255 is fixedly connected to the bottom surface of the impurity receiving hopper 253. It should be noted that the top surface of the unloading hopper 251 is in line with the bottom surface of the crushing trough 22, so that the shredded paper in the crushing trough 22 can directly enter the unloading hopper 251. The impurity receiving hopper 253 is arranged on the bottom surface of the chute 252 near the transmission mechanism 5. The impurity receiving hopper 253 can receive metal debris adsorbed by the magnetic separation mechanism 6 through magnetic force. After the impurity receiving hopper 253 collects the metal debris, it is transported to the external environment through the impurity conveying pipe 255, so that the metal debris in the shredded paper can be automatically separated from the shredded paper, ensuring that the shredded paper being recycled does not contain metal debris, 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 mechanism body 61, a magnetic separation disk 62 is provided on one side of the mechanism body 61, an air outlet duct 65 is connected to the other side of the mechanism body 61, and the air outlet duct 65 is fixedly connected to the fan casing 63 at one end away from the mechanism body 61, and an air inlet duct 64 is fixedly connected to the fan casing 63 on one side. It should be noted that the output shaft of the drive motor 4 is directly fixedly connected to the fan impeller in the fan casing 63, so that after the drive motor 4 is turned on, the power of the drive motor 4 can be transmitted to the fan impeller in the fan casing 63 through the output shaft, so that the fan impeller rotates at high speed, and the high-speed rotating fan impeller will be in the fan casing 63. The air generates centrifugal force. It should be noted that the end of the air inlet duct 64 away from the fan casing 63 extends out of the outside of the pulverizing device main body 1, so that the air inlet duct 64 can inhale air through the external environment of the pulverizing device main body 1, allowing the air to enter the fan casing 63. The fan impeller in the fan casing 63 then uses centrifugal force to transport the air through the air outlet duct 65 to the interior of the mechanism main body 61. A conveying channel is opened inside the mechanism main body 61, and the air can enter the magnetic separation disk 62 through the conveying channel, and finally be output by the magnetic separation disk 62, blowing the shredded paper, diverting the shredded paper, and preventing the shredded paper from entering the impurity collection bucket 253.

[0044] like Figure 5 and Figure 8 As shown, the magnetic separation disk 62 includes a rotating ring 621, and a plurality of electromagnetic blocks 622 are fixedly connected to the inner side of the rotating ring 621. A blowing groove 623 is opened between the plurality of electromagnetic blocks 622. The rotating ring 621 fits in the inner cavity of the impurity receiving bucket 253 and can rotate freely in the inner cavity of the impurity receiving bucket 253. It should be noted that the annular conductor block 254 provided on the inner side of the impurity receiving bucket 253 is used to transmit electrical energy to the electromagnetic block 622. Therefore, when the electromagnetic block 622 contacts the annular conductor block 254, the annular conductor block 254 will transmit electrical energy to the electromagnetic block 622, so that the electromagnetic block 622 generates a magnetic force. In this way, when the paper scraps pass through the magnetic separation disk 62, the magnetic force generated by the electromagnetic block 622 can absorb the metal debris contained therein, and because the magnetic separation disk 62 can blow out air, it can prevent the paper scraps from approaching the electromagnetic block 622 while also preventing the paper scraps from being sandwiched between the metal debris and the electromagnetic block 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 make the electromagnetic block 622 corresponding to the upper half of the magnetic separation disk 62 generate magnetic force, and when the magnetic separation disk 62 rotates in the impurity receiving hopper 253, the upper half of the area is exposed. In this way, it can be ensured that when the magnetic separation disk 62 rotates in the impurity receiving hopper 253, the exposed part is always in contact with the annular conductor block 254. The annular conductor block 254 can always transmit electrical energy to the electromagnetic block 622 on the magnetic separation disk 62, so that the electromagnetic block 622 generates magnetic force. When the electromagnetic block 622 adsorbs When the metal impurities follow and rotate to the lower half area on the magnetic separation disk 62, the electromagnetic block 622 will automatically disengage from the annular conductor block 254, so that the magnetic force of the corresponding electromagnetic block 622 will disappear, and the adsorption force generated by the electromagnetic block 622 will also disappear. The metal debris adsorbed on the electromagnetic block 622 will automatically fall to the bottom of the impurity receiving bucket 253 and be discharged through the impurity conveying pipe 255, so that the electromagnetic block 622 can automatically adsorb metal impurities and automatically discharge the metal impurities into the impurity receiving bucket 253 during the rotation in the impurity receiving bucket 253, thereby realizing the automatic separation of metal impurities in paper scraps.

[0045] like Figure 5 、 Figure 7 and Figure 8 As shown, a rotating shaft 624 is installed at the inner center position of the rotating ring 621, and a fixed gear 625 is fixedly connected to the end of the rotating shaft 624 away from the rotating ring 621. A first gear 626 is meshed with the side of the fixed gear 625, and 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 to the inside of the pulverizing device body 1 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, and the fixed gear 625 is meshed with the first gear 626, so that the rotating first gear 626 will also drive the fixed gear 625, and the fixed gear 625 drives the rotating ring 621 to rotate through the rotating shaft 624, so that the rotating ring 621 can stably rotate inside the impurity receiving bucket 253;

[0046] Since a blowing groove 623 is opened between the electromagnetic blocks 622, when the blowing groove 623 rotates to correspond to the conveying channel inside the mechanism body 61, the conveying channel inside the mechanism body 61 can convey air to the blowing groove 623, so that the blowing groove 623 can blow out air, and the blowing groove 623 is 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, there is always a blowing groove 623 on the inner side of the rotating ring 621 that rotates to correspond to the conveying channel inside the mechanism body 61, 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 is meshed on the side of the sun gear 51, a transmission ring gear 54 is meshed on the outside of the planetary gear 53, a driving gear 55 is meshed on the side of the transmission ring gear 54, a transmission gear 56 is meshed on the side of the driving gear 55, and a driven gear 57 is meshed on the side of the transmission gear 56 away from the driving gear 55. The driving gear 55 and the driven gear 57 are respectively connected to the first rotating shaft 231 and the second rotating shaft 233 for power, and the transmission ring gear 54 is meshed with the second gear 627. It should be noted that the output shaft of the drive motor 4 is fixedly connected to the center position of the sun gear 51, and the output shaft is fixedly connected to the fan impeller inside the fan housing 63 after passing through the sun gear 51. In this way, the drive motor 4 is turned on. After the machine 4 is turned on, the driving 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 installed with a fixed ring 52 through the rotating shaft. The fixed ring 52 is fixed to the side of the pulverizing device body 1 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 gears 53. Since the side of the transmission gear ring 54 is meshed with a driving gear 55, the rotating transmission gear ring 54 can drive the driving gear 55 to rotate, and the driving gear 55 is meshed with the driven gear 57 through the transmission gear 56. Therefore, the rotating driving gear 55 can drive the driven gear 57 through the transmission gear 56, so that the driven gear 57 and the driving 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 be rotated at the same speed and in the same direction. In other words, the first gear roller 232 and the second gear roller 234 can rotate at the same speed and in the same direction. When the waste paper material enters the position between the first gear roller 232 and the second gear roller 234, the first gear roller 232 and the second gear roller 234 can tear the waste paper material with the shredding teeth on their sides, and the waste paper material is formed into paper scraps.

[0049] Since the transmission gear ring 54 is engaged with the second gear 627, when the transmission gear ring 54 rotates, the second gear 627 is also driven to rotate, and the second gear 627 drives 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 shredding mechanism 2 can simultaneously realize the shredding process of the waste paper raw material and the magnetic separation mechanism 6 can automatically separate the metal impurities of the formed shredded paper. It is ensured that the recycled shredded paper does not contain metal debris, so as not to affect the subsequent processing of the shredded paper.

[0050] like Figures 1-9 As shown, the bottom of the crushing device body 1 is provided with a device base 11, the top surface of the device base 11 is fixedly connected to a collecting barrel 12, and the top surface of the collecting barrel 12 is fixedly connected to an arc-shaped baffle 13. It should be noted that the collecting barrel 12 is used to receive the shredded paper, and the arc-shaped baffle 13 is provided 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 collecting barrel 12. The collecting barrel 12 can be connected to the pulper, so that the separated shredded paper The shredded paper can be directly transported to the pulper through the collecting barrel 12, and the pulper will pulp the shredded paper. The material transmission method between the collecting barrel 12 and the pulper can be adaptively selected by those skilled in the art according to the spatial position between the collecting barrel 12 and the pulper. For example, when the collecting barrel 12 is at the top of the pulper, the shredded paper in the collecting barrel 12 can enter the pulper by free sliding. When the collecting barrel 12 is at the bottom of the pulper, the shredded paper in the collecting barrel 12 can enter the pulper through the conveyor belt.

[0051] Example 2

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

[0053] S1: Put the waste paper raw material into the feeding and pulverizing mechanism 2. The amount of the waste paper raw material is adaptively selected by those skilled in the art according to the volume of the feeding and pulverizing mechanism 2.

[0054] S2: Turn on the drive motor 4 through the control console 3. The drive motor 4 drives the feed shredder 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 materials entering the feed shredder mechanism 2. Under normal circumstances, the greater the weight of the waste paper raw materials entering the feed shredder mechanism 2, the faster the speed of the drive motor 4 is required to ensure that the feed shredder mechanism 2 can process the waste paper raw materials 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 ring gear 54 to rotate through the planetary gear 53, and the transmission ring gear 54 drives the driving gear 55 to rotate. The rotating driving 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 driving gear 55. The driving gear 55 and the driven gear 57 are respectively fixedly connected to the first rotating shaft 231 and the second rotating shaft 233. In this way, the driving gear 55 and the driven gear 57 rotate at the same speed and in the same direction.

[0055] S3: The feeding shredding mechanism 2 shreds the waste paper raw material into shredded paper scraps. 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, that is, the first gear roller 232 and the second gear roller 234 can rotate at the same speed and in the same direction. In this way, when the waste paper raw material enters the position between the first gear roller 232 and the second gear roller 234, the first gear roller 232 and the second gear roller 234 can tear the waste paper raw material through the shredding teeth on their sides, so that the waste paper raw material is formed into shredded paper scraps. The shredded paper scraps in the shredding chute 22 can directly enter the discharge chute 252 inside the discharge hopper 251.

[0056] S4: The magnetic separation mechanism 6 blows the paper scraps while magnetically adsorbing metal debris in the paper scraps and automatically removing the metal debris. Specifically, the transmission gear ring 54 drives the second gear 627, and the second gear 627 drives the first gear 626 to rotate synchronously. The rotating first gear 626 also drives the fixed gear 625, and the fixed gear 625 drives the rotating ring 621 to rotate through the rotating shaft 624, so that the rotating ring 621 rotates stably inside the impurity receiving hopper 253. The power of the driving motor 4 can be transmitted to the fan impeller in the fan housing 63 through the output shaft, so that the fan impeller rotates at high speed. The high-speed rotating fan impeller will generate centrifugal force for the air in the fan housing 63. When the blowing slot 623 rotates to correspond to the conveying channel inside the mechanism body 61, the conveying channel inside the mechanism body 61 can convey air to the blowing slot 623, so that the blowing slot 623 can blow out air to prevent paper scraps from entering the impurity receiving hopper 253.

[0057] S5: The separated paper scraps are recovered through the pulverizing device body 1. When the magnetic separation mechanism 6 blows the paper scraps, the arc-shaped baffle 13 can block the paper scraps and discharge the blocked paper scraps into the collecting barrel 12. The collecting barrel 12 is connected to the pulper. In this way, the separated paper scraps are directly transported to the pulper through the collecting barrel 12, and the pulper performs pulping on the paper scraps.
