Description

Technical Field

[0001] This utility model relates to the field of dual-shaft shredder technology, specifically to an automatic material sorting device for a dual-shaft shredder. Background Technology

[0002] A twin-shaft shredder is a material handling device commonly used in industrial production. It mainly consists of two parallel rotating shafts and multiple sets of blades mounted on the shafts. Driven by a motor, the two shafts rotate relative to each other in a specific direction and at a specific speed.

[0003] In existing technologies, dual-shaft shredders shred materials with various properties during use. When shredding plastic objects, there may be some metal on the plastic parts. Under the strong crushing capacity, the plastic parts can be effectively decomposed, and the metal will naturally separate from the plastic parts.

[0004] However, if the metal and plastic parts are not sorted in time after separation, they may mix together again when discharged. In this case, it is necessary to sort the different objects manually. However, manual sorting is not only slow, but also prone to omissions due to fatigue and other factors. Therefore, we propose an automatic material sorting device for a dual-shaft shredder. Utility Model Content

[0008] In some embodiments, a lead screw is provided on the inner wall of one side end of the extrusion plate, and the inner wall of one side end of the extrusion plate is rotatably connected to the outer side of the lead screw, and one end of the lead screw is rotatably connected to the inner end of the guide plate.

[0009] In some embodiments, a limiting plate is provided on the inner side of the guide plate, and one end of the limiting plate is fixedly connected to the inner side of the guide plate. One side of the limiting plate is slidably connected to the inner wall of one side of the extrusion plate.

[0010] In some embodiments, a connecting rod is provided on the top side of the center plate, the top side of the center plate is fixedly connected to the bottom end of the connecting rod, a spring is provided at the bottom end of the connecting rod, and the bottom end of the connecting rod is fixedly connected to the bottom end of the spring.

[0011] In some embodiments, a horizontal plate is provided at the top of the spring, the top of the spring is fixedly connected to the bottom side of the horizontal plate, the top of the horizontal plate is fixedly connected to the inner side of the guide plate, and the inner wall of the horizontal plate is through-connected to the outer side of the connecting rod.

[0012] In some embodiments, a second motor is provided at one end of the lead screw, and one end of the lead screw is fixedly connected to the output end of the second motor. One end of the second motor is fixedly connected to one side of the shredding chamber.

[0013] In some embodiments, a shredding roller is provided inside the shredding chamber, and the interior of the shredding chamber is rotatably connected to one end of the shredding roller. A motor is provided at the other end of the shredding roller, and the other end of the shredding roller is fixedly connected to the output end of the motor.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. The motor drives the shredding roller inside the shredding chamber to start shredding the object. After being broken down, the object falls onto the guide plate under the action of gravity. Therefore, an inner plate is designed in the guide plate, and an electromagnetic plate is installed on the inner wall of the inner plate. The electromagnetic plate can attract metal objects during the sliding process. Whether it is a combination of plastic and metal or a complex material mixed with other materials, as long as it contains metal components that can be attracted by electromagnetic force, it can be effectively separated under the action of this device.

[0016] 2. By starting the second motor, the lead screw rotates. Since the extrusion plate is threadedly connected to the lead screw, the extrusion plate will retract from its original position due to the rotation, gradually returning to its original position. Then, due to the retraction of the extrusion plate, the connecting rod installed on the middle plate is fixedly connected to the bottom side of the horizontal plate by the spring on the connecting rod. Thus, when the external force disappears, the spring elastically retracts, raising the height of the middle plate. During this process, the movable arm begins to change angle, and the naturally closed plate no longer engages with the guide plate, ultimately making the inner plate vertical. When the electromagnetic plate is closed, the object will fall naturally under gravity. Attached Figure Description

The outer side is fixedly connected, and a middle plate 18 is provided at the top of the movable arm 17. The top of the movable arm 17 is rotatably connected to the inner side of one end of the middle plate 18. A pressing plate 19 is provided on the top side of the middle plate 18. The top side of the middle plate 18 is slidably in contact with the bottom side of the pressing plate 19. A lead screw 110 is provided on the inner wall of one side end of the pressing plate 19. The inner wall of one side end of the pressing plate 19 is rotatably connected to the outer side of the lead screw 110. One end of the lead screw 110 is rotatably connected to the inner end of the guide plate 14. A limit plate 111 is provided on the inner side of the guide plate 14. The inner side of plate 14 is fixedly connected to one end of the limiting plate 111. One side of the limiting plate 111 is slidably connected to the inner wall of one side of the extrusion plate 19. A connecting rod 112 is provided on the top side of the middle plate 18. The top side of the middle plate 18 is fixedly connected to the bottom end of the connecting rod 112. A spring 113 is provided at the bottom end of the connecting rod 112. The bottom end of the connecting rod 112 is fixedly connected to the bottom end of the spring 113. A horizontal plate 114 is provided at the top end of the spring 113. The top end of the spring 113 is fixedly connected to the bottom side of the horizontal plate 114. The top end of the horizontal plate 114 is connected to the guide plate. The inner side of 14 is fixedly connected, the inner wall of the horizontal plate 114 is connected through the outer side of the connecting rod 112, one end of the lead screw 110 is provided with a motor 115, one end of the lead screw 110 is fixedly connected to the output end of the motor 115, one end of the motor 115 is fixedly connected to one side of the shredding chamber 11, the inside of the shredding chamber 11 is provided with a shredding roller 12, the inside of the shredding chamber 11 is rotatably connected to one end of the shredding roller 12, the other end of the shredding roller 12 is provided with a motor 13, and the other end of the shredding roller 12 is fixedly connected to the output end of the motor 13.

[0026] When using the automatic material sorting device of this type of twin-shaft shredder, because the shredder can shred objects with different properties, such as plastic objects which may contain metal substances, the object is placed into the shredding chamber 11. A motor 13 is installed on one side of the shredding chamber 11, and the shredding rollers 12 inside the shredding chamber 11 begin to shred the object. Furthermore, a guide plate 14 is designed inside the shredding chamber 11, located below the two shredding rollers 12. Naturally, after being broken down, the object falls onto the guide plate 14 under the influence of gravity. The guide plate 14 is triangular in shape. In order to separate metal objects from plastic objects during the contact between the material and the guide plate 14, an inner plate 15 is designed in the guide plate 14. An electromagnetic plate 16 is installed on the inner wall of the inner plate 15. The electromagnetic plate 16 can attract metal objects during the sliding process. Whether it is a combination of plastic and metal or a complex material with a mixture of other materials, as long as it contains metal components that can be attracted by electromagnetic force, it can be effectively separated under the action of this device. This feature enables the equipment to complete the sorting work stably and efficiently when facing materials of different sources and different compositions.

[0027] A movable arm 17 is connected to one side of the inner plate 15, and the other end of the movable arm 17 is movably connected to the center plate 18. Therefore, when the center plate 18 is adjusted, the angle of the movable arm 17 changes accordingly. Thus, when the inner plate 15 and guide plate 14 are in a closed state, the extrusion plate 19 is located on the center plate 18. At this time, by starting the motor 115, the lead screw 110 rotates. Since the extrusion plate 19 is threadedly connected to the lead screw 110, the extrusion plate 19 will retract from its original position due to the rotation. It gradually returns to its original position. Then, due to the retraction of the extrusion plate 19, the middle plate 18 is equipped with a connecting rod 112. The spring 113 on the connecting rod 112 is fixedly connected to the bottom side of the horizontal plate 114. Thus, when the external force disappears, the spring 113 elastically retracts, and the height of the middle plate 18 is raised. During this process, the movable arm 17 begins to change angle, and the naturally closed plate no longer fits with the guide plate 14, finally making the inner plate 15 vertical. Then, the metal material on the electromagnetic plate 16 can be processed.

[0028] Since the connecting rod 112 slides within the horizontal plate 114, the horizontal plate 114 ensures that the height of the middle plate 18 remains stable during the lifting process, preventing excessive fluctuations that could cause path deviation. Furthermore, during the movement of the extrusion plate 19, a limiting plate 111 is designed in the inner wall of one side. The limiting plate 111 ensures that the extrusion plate 19 moves smoothly during its slide, preventing the extrusion plate 19 from rotating due to the rotation of the lead screw 110.

[0029] Example 2: Please refer to Figures 1-5 The collection mechanism 2 includes a base 21, a telescopic rod 22 is provided on the top side of the base 21, the top side of the base 21 is fixedly connected to the bottom end of the telescopic rod 22, a bracket 23 is provided on the top end of the telescopic rod 22, the top end of the telescopic rod 22 is fixedly connected to the bottom side of the bracket 23, the inner wall of the bracket 23 is slidably connected to one bottom end of the collection box 24, and a shredding chamber 11 is provided on the top end of the base 21, the top end of the base 21 is fixedly connected to the bottom side of the shredding chamber 11.

[0030] When the inner plate 15 is in a vertical position, a base support 21 is designed on the bottom side of the shredding chamber 11. By extending the telescopic rod 22 on the base support 21, the bracket 23 is moved upwards from its original position. Then, the collection box 24 is installed on the bracket 23. The two move synchronously until they reach below the guide plate 14. At this time, the inner plate 15 will be located in the collection box 24. Subsequently, the adsorption capacity of the electromagnetic plate 16 is turned off, and the metal object will fall into the collection box 24. Finally, the collection box 24 is restored to its original height. Since the collection box 24 and the bracket 23 are slidably connected, the metal object inside can be processed by pulling the collection box 24 on the bracket 23. In this way, the operator only needs to put the material into the shredding chamber 11 at the beginning and pull the collection box 24 to process the metal object at the end. The collection process in between is fully automated. This greatly reduces the high-intensity actions such as frequent bending and carrying by manual labor, and significantly reduces the labor intensity of the operators.

[0031] Please see Figures 1-5The object is placed into the shredding chamber 11. A motor 13 is installed on one side of the shredding chamber 11. Driven by the motor 13, the shredding rollers 12 inside the shredding chamber 11 begin to shred the object. A guide plate 14 is designed inside the shredding chamber 11, located below the two shredding rollers 12. After being broken down, the object falls onto the guide plate 14 under the influence of gravity. The guide plate 14 is triangular. To separate metal and plastic objects during contact with the guide plate 14, an inner plate 15 is designed within the guide plate 14. An electromagnetic plate 16 is installed on the inner wall of the inner plate 15. The electromagnetic plate 16 attracts metal objects as they slide down. A movable arm 17 is connected to one side of the inner plate 15, and the other end of the movable arm 17 is movably connected to a center plate 18. This allows the center plate 18 to adjust its position. The angle of the movable arm 17 will also change accordingly. Therefore, when the inner plate 15 and the guide plate 14 are in the closed state, the extrusion plate 19 is located in the middle plate 18. At this time, by starting the motor 115, the lead screw 110 is rotated. Since the extrusion plate 19 is threadedly connected to the lead screw 110, the extrusion plate 19 will retract from its original position due to the rotation, gradually returning to its original position. Then, due to the retraction of the extrusion plate 19, the middle plate 18 is equipped with a connecting rod 112. The spring 113 on the connecting rod 112 is fixedly connected to the bottom side of the horizontal plate 114. Thus, when the external force disappears, the spring 113 elastically retracts and raises the height of the middle plate 18. During this process, the movable arm 17 begins to change angle, and the naturally closed plate no longer fits with the guide plate 14, finally making the inner plate 15 vertical so that the metal object on the electromagnetic plate 16 can be processed later.

[0032] Extend the telescopic rod 22 on the base 21 to a higher position, causing the bracket 23 to move upwards. Then, the collection box 24 is installed on the bracket 23. The two move synchronously until they reach below the guide plate 14. At this point, the inner plate 15 will be located in the collection box 24. Then, turn off the adsorption capacity of the electromagnetic plate 16, so that the metal object will fall into the collection box 24. Finally, return the collection box 24 to its original height. Since the collection box 24 and the bracket 23 are slidably connected, the metal object inside can be processed by pulling the collection box 24 on the bracket 23.
