Description

Technical Field

[0001] The present invention belongs to the technical field of environmental protection equipment, and particularly relates to a device for recycling mobile phone chargers. Background Art

[0002] In recent years, in the face of the severe situation of serious environmental pollution, resource constraints and ecosystem degradation, ecological civilization construction has been increasingly emphasized in all sectors of society. The essence of ecological civilization construction is to push sustainable development to the height of green development, plant trees for future generations, not leave regrets for future generations, but leave more ecological assets.

[0003] A lot of metal resources are contained in electronic waste, and a large number of metal resources including precious metals can be extracted after being processed through certain procedures. The grade of some precious metals is dozens or even hundreds of times that of natural mineral deposits, and the cost of recycling metal resources is often lower than the cost of mining in natural mineral deposits. Mobile phone chargers are a type of electronic waste. If the recycling of waste mobile phone chargers can be done well, it can contribute to alleviating the pressure of resource shortage and pollution control. At present, the first step in the treatment of mobile phone chargers in China is manual disassembly, supplemented by special equipment such as disassembly tables or robotic arms, and dust removal equipment is also equipped.

[0004] The existing treatment methods are time-consuming and laborious, and the treatment efficiency is relatively low. Summary of the Invention

[0005] In view of this, the purpose of the embodiments of the present invention is to provide a device for recycling mobile phone chargers, which can realize the automatic disassembly of mobile phone chargers. Just place the mobile phone charger to be disassembled at the entrance, and the disassembly can be automatically completed, realizing the separation of plastic and metal. The structure is simple, time-saving and labor-saving, and effectively improves the disassembly efficiency of mobile phone chargers.

[0006] The embodiments of the present invention are implemented as follows:

[0007] The embodiments of the present invention provide a device for recycling mobile phone chargers, and the recycling device includes a frame and a storage box, a transmission mechanism, a first stamping mechanism and a material separation mechanism arranged on the frame.

[0008] The top of the storage box is provided with a feed inlet and the bottom is provided with a discharge outlet. The starting end of the transmission mechanism is located below the discharge outlet, the first stamping mechanism is located above the transmission mechanism, and the material separation mechanism is located below the transmission mechanism.

[0009] The storage box is used to hold the mobile phone chargers to be disassembled. The mobile phone chargers in the storage box can fall onto the transmission mechanism one by one. The transmission mechanism drives the mobile phone chargers forward. When the mobile phone charger reaches the first stamping mechanism, the first stamping mechanism stamps and breaks the mobile phone charger. The broken metal and plastic both enter the material separation mechanism for material separation. The material separation mechanism can adopt a box mechanism and be manually separated, or can adopt an automated structure for material separation.

[0010] As an alternative to the above embodiment, the first stamping mechanism includes a first stamping cylinder, a second stamping cylinder, a first stamping plate and a second stamping plate. The first stamping cylinder and the second stamping cylinder are respectively fixed on the frame. The first stamping plate is fixed to the piston end of the first stamping cylinder. The second stamping plate is fixed to the piston end of the second stamping cylinder. The first stamping plate and the second stamping plate are arranged opposite to each other. Under the action of the first stamping cylinder and the second stamping cylinder, the first stamping plate and the second stamping plate can approach and move away from each other. The moving directions of the first stamping plate and the second stamping plate are parallel to the top surface of the conveyor belt.

[0011] The distance between the first stamping plate and the second stamping plate can be gradually reduced to perform a stamping operation on the mobile phone charger, and the plastic in the mobile phone charger can be crushed, so that the metal inserts are separated.

[0012] As an alternative to the above embodiment, the first stamping mechanism further includes an auxiliary device. The auxiliary device includes an auxiliary motor and a reciprocating member. The auxiliary motor and the reciprocating member are fixed on the frame. The first stamping cylinder is fixed on the reciprocating member. The auxiliary motor can drive the reciprocating member to move, so that the first stamping cylinder reciprocates along the conveying direction of the conveyor belt; a plurality of spherical protrusions are arranged on the first stamping plate, and the height of the protrusions is less than 1 mm.

[0013] The auxiliary device can make the first stamping cylinder reciprocate, so that the first stamping plate swings left and right while approaching the second stamping plate, so that the first stamping plate and the second stamping plate act together to perform a rubbing and crushing operation on the mobile phone charger, changing from simple extrusion to rubbing and crushing, similar to rubbing an object with both hands. This method has two advantages: First, when the insert is perpendicular to the first stamping plate and the second stamping plate, if simple extrusion and crushing are used, it is very difficult to crush the plastic on both sides of the insert. After adding the auxiliary device, due to the swing of the first stamping plate, the insert is tilted. At this time, the larger surface area of the insert will gradually change from a state perpendicular to the first stamping plate to a state parallel to the first stamping plate, which is convenient for crushing the plastic on both sides of the insert; Second, the crushing effect of combining rubbing with extrusion is better than that of simple extrusion and crushing.

[0014] As an alternative to the above embodiment, the first stamping plate adopts an electromagnet structure, and the

[0015] There are two second stamping cylinders. One of the second stamping cylinders is hinged to the second stamping plate. The piston end of the other second stamping cylinder is hinged with two sliders. There are two chutes arranged on the second stamping plate. The chutes extend vertically. The sliders are slidably arranged in the chutes. The hinged part of the second stamping cylinder and the second stamping plate and the two sliders are distributed in a triangle. The two second stamping cylinders expand and contract independently so that the second stamping plate can swing. The swing axis of the second stamping plate is parallel to the top surface of the conveyor belt.

[0016] The two stamping cylinders move simultaneously, causing the second stamping plate to swing while approaching the first stamping plate. The width of each part between the first stamping plate and the second stamping plate can change at any time. The inserts will always be adsorbed by the first stamping plate and cannot fall off, while the plastic separated from the inserts will gradually fall off and will not block between the first stamping plate and the second stamping plate, so that there is less debris between the first stamping plate and the second stamping plate, and the separation effect of plastic and metal is better.

[0017] As an alternative to the above embodiment, the recycling device further includes a second stamping mechanism. The second stamping mechanism is arranged downstream of the first stamping mechanism and above the material distribution box. The second stamping mechanism includes a second stamping cylinder, a stamping head and a third stamping plate. The second stamping cylinder is fixed on the frame. The stamping head is fixed on the piston end of the second stamping cylinder. The third stamping plate is arranged horizontally. The third stamping plate is inclined relative to the horizontal plane. The stamping head is provided with stamping rods distributed in a matrix. The third stamping plate is provided with stamping holes distributed in a matrix and corresponding to the stamping rods.

[0018] The second stamping mechanism can make the separation of metal and plastic more thorough. Moreover, the plastic can be divided into smaller particles or blocks and fall off, which is convenient for subsequent processing.

[0019] As an alternative to the above embodiment, the material distribution mechanism includes a material distribution box, a material distribution plate and a vibrator. The material distribution box has a material distribution cavity for accommodating plastic particles. The material distribution plate is arranged above the material distribution cavity and below the conveyor belt. The material distribution plate is inclined. The first stamping mechanism is located above the higher end of the material distribution plate. The vibrator is fixed on the material distribution box and is used to vibrate the material distribution plate. The material distribution plate is provided with leakage holes distributed in a matrix.

[0020] As an alternative to the above embodiment, the transmission mechanism includes two conveyor belts arranged side by side. There is a gap between the two conveyor belts for limiting the mobile phone charger. The width of the gap is smaller than the width of the side of the mobile phone charger with plug blades.

[0021] The recycling device further includes a cleaning mechanism. The cleaning mechanism includes two baffles. The baffles are arranged above the conveyor belt and downstream of the first stamping mechanism. The distance between the two baffles gradually decreases. The ends of the two baffles are located directly above the gap.

[0022] The baffle can recycle plastics and the like remaining on the conveyor belt.

[0023] As an alternative to the above embodiment, the recycling device further includes a picking hook. The picking hook includes a rotating shaft, a grasping rod and a suction attachment. The rotating shaft is rotatably supported on the frame around its own axis. The grasping rod extends radially along the rotating shaft. The suction attachment is fixed to the end of the grasping rod away from the rotating shaft and is used for adsorbing the mobile phone charger head. During the rotation of the rotating shaft, the suction attachment can pass through the gap and has a grasping state of entering the storage box to adsorb the mobile phone charger head, and a releasing state of placing the mobile phone charger head on the conveyor belt.

[0024] As an alternative to the above embodiment, the suction attachment adopts an electromagnet structure.

[0025] As an alternative to the above embodiment, the recycling device further includes an anti-tilting member. The anti-tilting member has magnetism and is used for adsorbing the plug blades of the mobile phone charger head. The anti-tilting member is arranged inside the conveyor belt and extends along the direction of the conveyor belt. The anti-tilting member is below the gap. The distance from the anti-tilting member to the top surface of the conveyor belt is less than the exposed length of the plug blade, so that there is a gap between the anti-tilting member and the plug blade.

[0026] The anti-tilting member can keep the plug blades always in the gap, making the processing more standardized and unified and the processing effect better.

[0027] The beneficial effects of the present invention are:

[0028] The mobile phone charger recycling device provided by the present invention can realize the automatic disassembly of mobile phone chargers. Just place the mobile phone chargers to be disassembled at the entrance, and the disassembly can be automatically completed, realizing the separation of plastics and metals. The structure is simple, time-saving and labor-saving, effectively improving the disassembly efficiency of mobile phone chargers. Description of the Drawings

[0048] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0049] In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0050] First embodiment

[0051] Please refer to Figures 1-3 As shown, the first embodiment of the present invention provides a mobile phone charger recycling device 10. This recycling device 10 is used for disassembling mobile phone chargers, that is, separating the metal and plastic of mobile phone chargers, so as to achieve the purpose of classified recycling.

[0052] The mechanisms of the recycling device 10 are as follows:

[0053] The recycling device 10 includes a frame, and a storage box 11, a transmission mechanism 12, a first stamping mechanism 13, and a material distribution mechanism 14 provided on the frame.

[0054] Please refer to Figure 4 As shown, the top of the storage box 11 is provided with a feed inlet and the bottom is provided with a discharge outlet. The storage box 11 is used to accommodate mobile phone chargers to be disassembled, and the mobile phone chargers can be exposed from the discharge outlet.

[0055] From the perspective of the recycling efficiency of mobile phone chargers, the larger the size of the storage box 11, the more charger plugs that can be stored in the storage box 11 at the same time. On the contrary, when the volume of the box is small, it is necessary to frequently add materials to the storage box 11, which will reduce the recycling efficiency of mobile phone chargers. Therefore, under the condition of allowing space, the size of the storage box 11 should be increased as much as possible to accommodate more charger plugs and reduce the feeding frequency.

[0056] In this embodiment, the length and width of the bottom of the storage box 11 are both 100 mm, and the height is 138.37 mm. In order to obtain a larger storage volume, the back of the storage box 11 is inclined to accommodate more charger plugs.

[0057] The starting end of the transmission mechanism 12 is located below the discharge outlet.

[0058] The transmission mechanism 12 can adopt a traditional belt structure. In this embodiment, the transmission mechanism 12 includes two belts arranged side by side. There is a gap for limiting the mobile phone charger between the two belts, and the width of the gap is smaller than the width of the side of the mobile phone charger with plug blades.

[0059] When the mobile phone charger reaches the belt, the plug blades of the mobile phone charger can be located in the gap and kept upright.

[0060] Specifically, the transmission mechanism 12 includes a transmission motor for providing power, a speed reducer for matching the rotational speed and transmitting torque, a belt for conveying mobile phone chargers, and a belt for driving the material taking device to rotate.

[0061] The speed reducer reduces the high rotational speed provided by the transmission motor by meshing a gear with fewer teeth on the input shaft of the gear speed reducer with a gear with more teeth on the output shaft to achieve the purpose of reducing the rotational speed and matching it with the lower rotational speed of the belt as the actuator.

[0062] The distance between the two conveyor belts is less than the minimum side length of the bottom surface of the mobile phone charger plug, preventing the mobile phone charger plug from falling through the middle. However, the distance cannot be too small and needs to be greater than the distance between the two metal inserts of the mobile phone charger plug. Through measurement, it is known that the distance between the metal inserts of a general mobile phone charger is about 10.3 mm, and the width of the bottom surface of the mobile phone charger plug is generally between 25 mm and 40 mm. Therefore, the distance between the two conveyor belts should be greater than 11 mm and less than 20 mm. In the mobile phone charger recycling device 10, the distance between the two conveyor belts is taken as 18 mm.

[0063] In terms of selecting the travel length of the conveyor belt, considering that the crushing of the plastic shell of the mobile phone charger needs to be realized on the conveyor belt and a relatively long conveyor belt travel is required, the conveyor belt travel length is taken as 500 mm.

[0064] The following is the mechanical calculation of the transmission mechanism 12:

[0065] The friction force between the plug of the mobile phone charger and the conveyor belt is related to the weight of the mobile phone charger and the friction coefficient between them. By looking up relevant data, it is known that the weight of a general mobile phone charger plug is about 60 g, and the friction coefficient is about 0.2.

[0066] According to the friction force formula, let the friction force be represented by F. The calculation formula for the friction force F is:

[0067] F = μ × F N

[0068] In the formula, μ—the friction coefficient between the charger and the conveyor belt;

[0069] F N —the pressure exerted by the charger on the conveyor belt, N;

[0070] The calculated friction force is approximately 0.12 N. When the plug of the mobile phone charger moves horizontally and uniformly on the conveyor belt, the friction force is zero. Therefore, the actual traction force required for the conveyor belt movement is very small, and the corresponding load on the motor can also be ignored. Therefore, from the perspective of energy conservation and cost reduction, a motor with a relatively low power should be selected as much as possible. Finally, considering the performance requirements comprehensively, a micro speed control motor with a power of 15 W and an unloaded speed of 480 r / min is selected.

[0071] In terms of the selection of the conveyor belt speed, the required driving speed of the mobile phone charger recycling device 10 is relatively small, and it is more appropriate to be between about 100 mm / s and 200 mm / s. The pulley diameter of the conveyor belt is 100 mm. From this, the rotational speed of the pulley can be calculated to be between 60 r / min and 120 r / min. Considering from the perspective of production efficiency, the pulley rotational speed is taken as 120 r / min, and the conveyor belt speed is 200 mm / s. Finally, according to the output rotational speed of the motor and the required rotational speed of the conveyor belt pulley, the required reduction ratio of the reducer is determined to be i = 4.

[0072] The first stamping mechanism 13 is located above the transmission mechanism 12. Among them, the first stamping mechanism 13 includes a first stamping cylinder 130, a second stamping cylinder 131, a first stamping plate 132, and a second stamping plate 133.

[0073] The first stamping cylinder 130 and the second stamping cylinder 131 are respectively fixed to the machine frame. The first stamping plate 132 is fixed to the piston end of the first stamping cylinder 130, and the second stamping plate 133 is fixed to the piston end of the second stamping cylinder 131. The first stamping plate 132 and the second stamping plate 133 are arranged oppositely.

[0074] Under the action of the first stamping cylinder 130 and the second stamping cylinder 131, the first stamping plate 132 and the second stamping plate 133 can approach and move away from each other.

[0075] The moving directions of the first stamping plate 132 and the second stamping plate 133 are parallel to the top surface of the conveyor belt.

[0076] The distance between the first stamping plate 132 and the second stamping plate 133 can be gradually reduced to perform a stamping operation on the mobile phone charger, and the plastic in the mobile phone charger can be crushed, so that the metal inserts are separated.

[0077] The material distribution mechanism 14 is located below the transmission mechanism 12.

[0078] The material distribution mechanism 14 can adopt an ordinary box body, that is, the disassembled metal and plastic both fall into its interior and are separated manually. It can also adopt the following structure:

[0079] Please refer to Figure 5 、 Figure 6 As shown, the material distribution mechanism 14 includes a material distribution box 140, a material distribution plate 141, and a vibrator 142 (please refer to Figure 1 As shown), the material distribution box 140 has a material distribution cavity for accommodating plastic particles. The material distribution plate 141 is arranged above the material distribution cavity and below the conveyor belt. The material distribution plate 141 is inclined. The first stamping mechanism 13 is located above the higher end of the material distribution plate 141. The vibrator 142 is fixed to the material distribution box 140 and is used to vibrate the material distribution plate 141. The material distribution plate 141 is provided with leakage holes distributed in a matrix.

[0080] The mobile phone chargers in the storage box 11 can fall onto the transmission mechanism 12 one by one. The transmission mechanism 12 drives the mobile phone chargers forward. When the mobile phone chargers reach the first stamping mechanism 13, the first stamping mechanism 13 stamps and crushes the mobile phone chargers. The crushed metal and plastic both enter the material separation mechanism 14 for material separation. The material separation mechanism 14 can adopt a box body mechanism and be manually separated, or can adopt an automated structure for material separation.

[0081] In addition, the recycling device 10 can also have the following mechanisms:

[0082] The recycling device 10 further includes a second stamping mechanism 15, a cleaning mechanism 16 and a material taking hook 17. The second stamping mechanism 15 is arranged downstream of the first stamping mechanism 13 and above the material separation box 140.

[0083] Please refer to Figure 7 、 Figure 8 As shown, the second stamping mechanism 15 includes a third stamping cylinder 150 (please refer to Figure 1 shown), a stamping head 151 and a third stamping plate 152.

[0084] Specifically, the third stamping cylinder 150 is fixed to the frame, the stamping head 151 is fixed to the piston end of the third stamping cylinder 150, the third stamping plate 152 is arranged horizontally, and the third stamping plate 152 is inclined relative to the horizontal plane.

[0085] The stamping head 151 is provided with stamping rods distributed in a matrix, and the third stamping plate 152 is provided with stamping holes distributed in a matrix and corresponding to the stamping rods.

[0086] The second stamping mechanism 15 can make the separation of metal and plastic more thorough, and the plastic can be divided into smaller particles or blocks and fall, which is convenient for subsequent processing.

[0087] Please refer to Figure 9 As shown, the cleaning mechanism 16 includes two baffles 160. The baffles 160 are arranged above the conveyor belt and downstream of the first stamping mechanism 13. The distance between the two baffles 160 gradually decreases, and the ends of the two baffles 160 are located directly above the gap.

[0088] The baffle 160 can recycle the plastic remaining on the conveyor belt, etc.

[0089] Please refer to Figure 10 As shown, the material taking hook 17 includes a rotating shaft 170, a grasping rod 171 and a suction attachment 172.

[0090] The rotating shaft 170 is rotatably supported on the frame about its own axis. The grasping rod 171 extends radially along the rotating shaft 170. The adsorbing member 172 is fixed to one end of the grasping rod 171 away from the rotating shaft 170 and is used for adsorbing the mobile phone charger head.

[0091] During the rotation of the rotating shaft 170, the adsorbing member 172 can pass through the gap and has a grasping state of entering the storage box 11 to adsorb the mobile phone charger head, and a releasing state of placing the mobile phone charger head on the conveyor belt.

[0092] As an alternative to the above embodiment, the adsorbing member 172 adopts an electromagnet structure.

[0093] Second Embodiment

[0094] Please refer to Figure 11 As shown, the first embodiment of the present invention provides a mobile phone charger recycling device 10. This recycling device 10 is a further improvement based on the first embodiment. For parts not mentioned in this embodiment, reference can be made to the first embodiment.

[0095] It should be noted that the first embodiment is not immutable. For example, the structure of the sorting bin 140 can adopt the two mentioned types, and the second embodiment can be improved respectively for these two schemes. For another example, the second embodiment may not have structures such as the second stamping mechanism 15, the cleaning mechanism 16, and the picking hook 17.

[0096] The difference from the first embodiment is that the first stamping mechanism 13 further includes an auxiliary device 134. The auxiliary device 134 includes an auxiliary motor 135 and a reciprocating member 136.

[0097] Among them, the auxiliary motor 135 and the reciprocating member 136 are fixed on the frame, the first stamping cylinder 130 is fixed on the reciprocating member 136, and the auxiliary motor 135 can drive the reciprocating member 136 to move so that the first stamping cylinder 130 reciprocates along the conveying direction of the conveyor belt.

[0098] The structure of the reciprocating member 136 is not limited. For example, a crank-slider 137, a ball screw that can rotate forward and backward by the motor, etc. can be adopted.

[0099] A plurality of spherical protrusions are provided on the first stamping plate 132, and the height of the protrusions is less than 1 mm.

[0100] The protrusions mainly increase the pressure of each part and make the grasping more firm. The height of the protrusions cannot be too large, otherwise it will cause

[0101] The auxiliary device 134 can make the first stamping cylinder 130 reciprocate, so that the first stamping plate 132 swings left and right while approaching the second stamping plate 133, so that the first stamping and the second stamping plate 133 act together to crush the mobile phone charger, changing from simple extrusion to crushing, similar to rubbing an object with both hands.

[0102] This method has two advantages: First, when the insert is perpendicular to the first stamping plate 132 and the second stamping plate 133, if simple extrusion crushing is used, it is very difficult to crush the plastic on both sides of the insert. After adding the auxiliary device 134, due to the swing of the first stamping plate 132, the insert is tilted. At this time, the larger side of the insert will gradually change from a state perpendicular to the first stamping plate 132 to parallel to the first stamping plate 132, which is convenient for crushing the plastic on both sides of the insert; Second, the crushing effect of combining rubbing while extruding is better than that of simple extrusion crushing.

[0103] In this embodiment, the first stamping plate 132 adopts an electromagnet structure.

[0104] The number of the second stamping cylinders 131 is two. One of the second stamping cylinders 131 is hinged to the second stamping plate 133. Please refer to Figure 12 As shown, the piston end of the other second stamping cylinder 131 is hinged with two sliders 137. Two chutes are arranged on the second stamping plate 133. The chutes extend vertically. The sliders 137 are slidably arranged in the chutes. The hinged part of the second stamping cylinder 131 and the second stamping plate 133 and the two sliders 137 are distributed in a triangle.

[0105] The two second stamping cylinders 131 expand and contract independently so that the second stamping plate 133 can swing. The swing axis of the second stamping plate 133 is parallel to the top surface of the conveyor belt.

[0106] The two stamping cylinders move simultaneously, so that the second stamping plate 133 swings while approaching the first stamping plate 132. The width of each part between the first stamping plate 132 and the second stamping plate 133 can change at any time, and the insert will always be adsorbed by the first stamping plate 132 and cannot fall off. The plastic separated from the insert will gradually fall off and will not block between the first stamping plate 132 and the second stamping plate 133, so that there is less debris between the first stamping plate 132 and the second stamping plate 133, and the separation effect of plastic and metal is better.

[0107] As an alternative to the above embodiment, the recycling device 10 further includes an anti-tilting member 18 (not shown in the figure).

[0108] The anti-tilting member 18 is magnetic and used to adsorb the plug of the mobile phone charger. The anti-tilting member 18 is arranged inside the conveyor belt and extends along the direction of the conveyor belt. The anti-tilting member 18 is located below the gap, and the distance from the anti-tilting member 18 to the top surface of the conveyor belt is less than the exposed length of the plug, so that there is a gap between the anti-tilting member 18 and the plug.

[0109] The anti-tilting member 18 can keep the plug always located in the gap, making the processing more standardized and unified and the processing effect better.

[0110] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
