DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0037] Example 1

[0038] See also Figure 1-Figure 11 , the present invention provides a technical solution:

[0039] An energy-saving solid waste crushing device comprises a mounting frame 1, a cylinder 2 and a first crushing knife 3, and further comprises:

[0040] The second crushing knife 4 corresponds to the first crushing knife 3 one by one and is movably fitted with the first crushing knife 3. This design enables the first crushing knife 3 and the second crushing knife 4 to be separated and fitted, thereby changing the crushing range of the tool.

[0041] The separation mechanism 5 is arranged on the cylinder 2, and the second crushing knife 4 is arranged on the separation mechanism 5. When the size of the paper scraps is gradually reduced, the separation mechanism 5 is used to drive the second crushing knife 4 to move and separate from the first crushing knife 3 to increase the crushing range of the paper scraps.

[0042] The advantage of setting up the separation mechanism 5 is that a plurality of first crushing knives 3 and second crushing knives 4 are designed to fit together, and they are separated when the size of the paper scraps gradually becomes smaller, so as to expand the crushing range of the paper scraps. As the size of the paper scraps decreases, the fit between the first crushing knife 3 and the second crushing knife 4 gradually decreases, which can ensure that smaller paper scraps can also be effectively crushed. At the same time, the separation of the first crushing knife 3 and the second crushing knife 4 allows the paper scraps to more fully contact the crushing knife during the crushing process and be subjected to more crushing force, which helps to crush the paper scraps into smaller particles and improve the uniformity and fineness of the crushing. Since the design of the first crushing knife 3 and the second crushing knife 4 can crush the paper scraps more efficiently, the energy consumption required for the entire crushing process will also be reduced accordingly, which helps to reduce production costs and improve the economy of the equipment.

[0043] The deflection mechanism 10 is arranged on the separation mechanism 5. The deflection mechanism 10 is used to control the deflection of the second crushing knife 4 while the second crushing knife 4 moves, thereby changing the crushing angle of the second crushing knife 4 for the paper scraps.

[0044] The advantage of setting up the deflection mechanism 10 is that, during the waste paper shredding process, the crushing angle of the second crushing knife 4 is changed while the first crushing knife 3 and the second crushing knife 4 are separated. Changing the crushing angle can make the crushing knife better adapt to paper scraps of different sizes and shapes during the crushing process. As the size of the paper scraps decreases, by adjusting the crushing angle, it can be ensured that the second crushing knife 4 cuts into the paper scraps more effectively, thereby speeding up the crushing speed and improving the crushing efficiency. At the same time, because different crushing angles will produce different crushing forces and shearing effects, by adjusting the crushing angle in a timely manner, the shape of the paper scraps during the crushing process can be better controlled to make them more uniform and fine, which helps to improve the quality of waste paper recycling and provide better raw materials for subsequent processing and reuse. Not only that, in the waste paper shredding, factors such as the type, thickness and humidity of the waste paper may affect the crushing effect. By designing a second crushing knife 4 that can change the crushing angle, the crushing device can better adapt to different types of waste paper. This design improves the flexibility and adaptability of the crushing device, enabling it to cope with more diverse crushing needs.

[0045] The separation mechanism 5 includes a discrete part 6 arranged on the cylinder 2, and the discrete part 6 is used to control the movement of the second crushing knife 4. The cylinder 2 is provided with a power part 7, and the power part 7 is used to provide power for the discrete part 6 to work. The power part 7 is provided with a transmission part 8, and the power provided by the power part 7 is transmitted by the transmission part 8. The transmission part 8 is provided with a reset part 9, and the reset part 9 is used to control the reset of the second crushing knife 4 after the crushing of the paper scraps is completed.

[0046] The discrete member 6 includes a rotating tube 61 rotatably arranged on the cylinder 2, a power shaft 62 is rotatably arranged in the cylinder 2, the power shaft 62 penetrates the rotating tube 61 and is rotatably connected with the rotating tube 61, a plurality of bidirectional screws 63 are arranged on the power shaft 62, a fixed plate 1 64 is arranged in the rotating tube 61, the fixed plate 1 64 is rotatably connected with the power bidirectional screw 63, a fixed plate 2 65 is slidably arranged on both sides of the fixed plate 1 64 in the rotating tube 61, the fixed plate 2 65 is movably connected with the bidirectional screw 63, and a traction block 66 is arranged at both ends of the bidirectional screw 63, the traction block 66 is rotatably connected to the fixed plate 2 65, the traction block 66 is threadedly connected to the bidirectional screw 63, a limit block 67 is arranged on the traction block 66, the limit block 67 is slidably connected to the rotating tube 61, a plurality of sliding grooves 68 are opened on the rotating tube 61, a plurality of extension shafts 69 are arranged on the fixed plate 1 64, the extension shaft 1 69 passes through the sliding groove 68, the extension shaft 1 69 is connected to the first crushing knife 3, a plurality of extension shafts 2 610 are rotatably arranged on the fixed plate 2 65, the extension shaft 2 610 passes through the sliding groove 68, and the extension shaft 2 610 is connected to the second crushing knife 4.

[0047] The rotating tube 61 is connected to the power output end of the motor. This is a prior art and will not be described in detail here.

[0048] The advantage of setting the discrete parts 6 is that the distance between the first crushing knife 3 and the second crushing knife 4 can be adjusted according to the degree of crushing of the paper scraps during the crushing process, thereby expanding the crushing range of the crushing knife for the paper scraps, which helps to crush the paper scraps into smaller particles and improve the uniformity and fineness of the crushing.

[0049] The power member 7 includes a power gear 1 71 arranged on the rotating tube 61, a plurality of rotating shafts 72 are rotatably arranged on the cylinder 2, a plurality of reduction gear sets 73 are arranged on the rotating shafts 72, and the reduction gear sets 73 are meshed with the power gear 1 71, a transmission shaft 74 is rotatably arranged on the cylinder 2, and a power gear 2 75 meshed with the reduction gear set 73 is arranged on the transmission shaft 74.

[0050] The transmission member 8 includes a positioning shaft 81 rotatably arranged on the cylinder 2, the positioning shaft 81 and the transmission shaft 74 are both provided with a power pulley 82, the power pulley 82 is provided with a power belt 83, the positioning shaft 81 is slidably provided with a transmission gear ring 84, the inner ring of the transmission gear ring 84 is provided with a push rod 85, the positioning shaft 81 is provided with a spiral groove 86, the push rod 85 is slidably connected with the spiral groove 86, the cylinder 2 is provided with a positioning plate 87, the positioning plate 87 is slidably provided with a sliding The movable rod 88 is provided with a locking block 89 used in conjunction with the transmission gear ring 84 on the sliding rod 88, and a return spring 810 is sleeved between the locking block 89 and the positioning plate 87 of the sliding rod 88. A push plate 811 is slidably provided on the positioning shaft 81, and a push block 812 used in conjunction with the push plate 811 is provided at the end of the sliding rod 88. The push block 812 is a wedge-shaped block, and a transmission gear 813 used in conjunction with the transmission gear ring 84 is provided at one end of the power shaft 62 located outside the cylinder 2.

[0051] The reset member 9 includes a fixed frame 91 arranged on the barrel 2, and the fixed frame 91 is rotatably connected to the power shaft 62. A clockwork box 92 is arranged on the fixed frame 91, and the power shaft 62 passes through the clockwork box 92 and is rotatably connected to the clockwork box 92. A clockwork spring 93 is arranged in the clockwork box 92, and one end of the clockwork spring 93 is connected to the power shaft 62.

[0052] When shredding waste paper, the staff first starts the motor to drive the rotating tube 61 to rotate, and simultaneously drives the fixed plate 1 64 and the fixed plate 2 65 to rotate, and further drives the extension shaft 1 69 and the extension shaft 2 610 to rotate. At this time, the first crushing knife 3 and the second crushing knife 4 connected to the extension shaft 1 69 and the extension shaft 2 610 rotate with the rotating tube 61 to crush the waste paper in the cylinder 2. The paper scraps gradually become smaller during the crushing of the first crushing knife 3 and the second crushing knife 4.

[0053] When the rotating tube 61 rotates, it drives the power gear 1 71 arranged thereon to rotate. The power gear 1 71 drives the reduction gear set 73 and the rotating shaft 72 meshed therewith to rotate. Under the transmission of the multiple reduction gear sets 73, the power is transmitted to the power gear 2 75 and the transmission shaft 74, and the rotation speed of the transmission shaft 74 slows down. When the transmission shaft 74 rotates, it drives the positioning shaft 81 to rotate through the power pulley 82 and the power belt 83. When the positioning shaft 81 rotates, it pushes the transmission gear ring 84 to move up and mesh with the transmission gear 813 through the spiral groove 86. Due to the setting of the positioning block 89, when the positioning shaft 81 rotates, the transmission gear ring 84 will not rotate with the positioning shaft 81, and when the transmission gear ring 84 and When the transmission gear 813 is engaged, under the push of the pushing plate 811, the pushing block 812 and the blocking block 89 are pushed away from the transmission gear 813, so that the transmission ring gear 84 can rotate normally. The transmission ring gear 84 rotates, driving the transmission gear 813 to rotate, and further driving the power shaft 62 to rotate. While the power shaft 62 rotates, it drives the clockwork spring 93 to store force. The rotation of the power shaft 62 drives the two-way screw rod 63 to rotate, thereby controlling the movement of the traction block 66 threadedly connected to the two-way screw rod 63. The movement of the traction block 66 drives the fixed plate 2 65 connected thereto to move, and drives the second crushing knife 4 to move, so that the distance between the first crushing knife 3 and the second crushing knife 4 becomes larger, thereby expanding the crushing range of the paper scraps.

[0054] When the paper scraps are crushed and it is necessary to control the first crushing knife 3 and the second crushing knife 4 to reset, the motor is controlled to reverse, driving the positioning shaft 81 to reverse, and the spiral groove 86 can be used to control the transmission ring gear 84 to descend and disengage from the transmission gear 813. At this time, the transmission gear 813 is disengaged, and the clockwork spring 93 releases power to drive the power shaft 62 to rotate in the opposite direction, thereby controlling the second crushing knife 4 to reset. At the same time, the positioning block 89 re-locks the transmission ring gear 84 under the push of the reset spring 810.

[0055] The deflection mechanism 10 includes a rotating member 11 disposed on the second fixing plate 65 , and the rotating member 11 is used to control the deflection of the second crushing knife 4 . A driving member 12 is disposed on the first fixing plate 64 , and the driving member 12 is used to provide power for the rotating member 11 to work.

[0056] The rotating member 11 includes a locking plate 111 disposed on the second fixing plate 65 , a rotating shaft 112 is rotatably disposed on the locking plate 111 , a worm 113 is disposed on the rotating shaft 112 , and a worm wheel 114 engaged with the worm 113 is disposed on the second extension shaft 610 .

[0057] The advantage of setting the rotating part 11 is that the crushing angle of the second crushing knife 4 is changed while the first crushing knife 3 and the second crushing knife 4 are separated. Changing the crushing angle can make the crushing knife better adapt to paper scraps of different sizes and shapes during the crushing process. As the size of the paper scraps decreases, by adjusting the crushing angle, it can be ensured that the second crushing knife 4 cuts into the paper scraps more effectively, thereby accelerating the crushing speed and improving the crushing efficiency.

[0058] The driving member 12 includes a plurality of extension rods 121 disposed on the fixing plate 1 64 . A pushing rack 122 is disposed on the extension rods 121 . A driving gear 123 engaged with the pushing rack 122 is disposed on the rotating shaft 112 .

[0059] When the fixed plate 65 drives the second crushing knife 4 to move, the driving gear 123 arranged on the fixed plate 65 is also driven to move synchronously. After moving a certain distance, the driving gear 123 engages with the pushing rack 122. At this time, the driving gear 123 rotates under the push of the pushing rack 122, driving the rotating shaft 112 to rotate synchronously. The rotation of the rotating shaft 112 drives the worm 113 to rotate. The rotation of the worm 113 drives the worm wheel 114 arranged on the extension shaft 610 to rotate. At the same time, because the worm 113 has a self-locking function, the worm 113 cannot be driven to rotate by the rotation of the worm wheel 114, thereby ensuring the stability of the second crushing knife 4.

[0060] When in use, when shredding waste paper, the staff first starts the motor to drive the rotating tube 61 to rotate, and simultaneously drives the fixed plate 1 64 and the fixed plate 2 65 to rotate, and further drives the extension shaft 1 69 and the extension shaft 2 610 to rotate. At this time, the first crushing knife 3 and the second crushing knife 4 connected to the extension shaft 1 69 and the extension shaft 2 610 rotate with the rotating tube 61 to crush the waste paper in the cylinder 2. The paper scraps gradually become smaller during the crushing of the first crushing knife 3 and the second crushing knife 4.

[0061] When the rotating tube 61 rotates, it drives the power gear 1 71 arranged thereon to rotate. The power gear 1 71 drives the reduction gear set 73 and the rotating shaft 72 meshed therewith to rotate. Under the transmission of the multiple reduction gear sets 73, the power is transmitted to the power gear 2 75 and the transmission shaft 74, and the rotation speed of the transmission shaft 74 slows down. When the transmission shaft 74 rotates, it drives the positioning shaft 81 to rotate through the power pulley 82 and the power belt 83. When the positioning shaft 81 rotates, it pushes the transmission gear ring 84 to move up and mesh with the transmission gear 813 through the spiral groove 86. Due to the setting of the positioning block 89, when the positioning shaft 81 rotates, the transmission gear ring 84 will not rotate with the positioning shaft 81, and when the transmission gear ring 84 and When the transmission gear 813 is engaged, under the push of the pushing plate 811, the pushing block 812 and the blocking block 89 are pushed away from the transmission gear 813, so that the transmission ring gear 84 can rotate normally. The transmission ring gear 84 rotates, driving the transmission gear 813 to rotate, and further driving the power shaft 62 to rotate. While the power shaft 62 rotates, it drives the clockwork spring 93 to store force. The rotation of the power shaft 62 drives the two-way screw rod 63 to rotate, thereby controlling the movement of the traction block 66 threadedly connected to the two-way screw rod 63. The movement of the traction block 66 drives the fixed plate 2 65 connected thereto to move, and drives the second crushing knife 4 to move, so that the distance between the first crushing knife 3 and the second crushing knife 4 becomes larger, thereby expanding the crushing range of the paper scraps.

[0062] When the fixed plate 65 drives the second crushing knife 4 to move, the driving gear 123 arranged on the fixed plate 65 is also driven to move synchronously. After moving a certain distance, the driving gear 123 engages with the pushing rack 122. At this time, the driving gear 123 rotates under the push of the pushing rack 122, driving the rotating shaft 112 to rotate synchronously. The rotation of the rotating shaft 112 drives the worm 113 to rotate. The rotation of the worm 113 drives the worm wheel 114 arranged on the extension shaft 610 to rotate. At the same time, because the worm 113 has a self-locking function, the worm 113 cannot be driven to rotate by the rotation of the worm wheel 114, thereby ensuring the stability of the second crushing knife 4.

[0063] When the paper scraps are crushed and it is necessary to control the first crushing knife 3 and the second crushing knife 4 to reset, the motor is controlled to reverse, driving the positioning shaft 81 to reverse, and the spiral groove 86 can be used to control the transmission ring gear 84 to descend and disengage from the transmission gear 813. At this time, the transmission gear 813 is disengaged, and the clockwork spring 93 releases power to drive the power shaft 62 to rotate in the opposite direction, thereby controlling the second crushing knife 4 to reset. At the same time, the positioning block 89 re-locks the transmission ring gear 84 under the push of the reset spring 810.
