Description

Technical Field

[0001] The present invention relates to the technical field of household appliance disassembly devices, and specifically, it is a household appliance recycling and disassembly device. Background Art

[0002] With the rapid replacement of household appliances, the recycling and disassembly of waste household appliances have become an important link in resource recycling. As a common household appliance, the outer shell of a refrigerator is usually composed of a metal outer layer, a filling layer (such as polyurethane foam), and a lining (such as a plastic layer). Traditional refrigerator disassembly methods mainly rely on manual operation or simple mechanical separation, with low disassembly efficiency and poor separation effect between the filling layer and the metal outer layer and inner layer; especially for some refrigerators with uneven outer shell structures, it is more difficult to clean the filling layer at the sunken positions.

[0003] To solve the above problems, the present application provides a household appliance recycling and disassembly device to improve the disassembly efficiency and effect and facilitate household appliance recycling. Summary of the Invention

[0004] To solve the above problems, the present invention provides a household appliance recycling and disassembly device.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a household appliance recycling and disassembly device, including a disassembly part for disassembling the metal outer layer, filling layer, and lining of the household appliance outer shell, including two parallel disassembly rollers for separating the metal outer layer and the filling layer, and the filling layer and the lining, and cleaning the fillers on the metal outer layer and the lining. The disassembly roller includes an outer roller, an intermediate roller, and an inner roller from outside to inside in sequence. The intermediate roller includes a plurality of driving segments, and a plurality of separating steel wires are evenly arranged outside the driving segments. The outer roller is provided with connecting holes, and the separating steel wires pass through the connecting holes and are arranged outside the disassembly roller. The intermediate roller is a lockable structure with both the outer roller and the inner roller. When the intermediate roller is locked with the outer roller, the exposed length of the separating steel wire is fixed. When the intermediate roller is locked with the inner roller, the intermediate roller is separated from the outer roller, and the separating steel wire can extend outwards to form a strengthened cleaning part; An auxiliary disassembly part is arranged on both sides of the household appliance outer shell for connecting the metal outer layer and the lining and pulling the metal outer layer and the lining to separate in opposite directions, including an auxiliary telescopic rod and a connecting disc. The extending end of the auxiliary telescopic rod is connected to the connecting disc, and the connecting disc is adsorbed and connected to the household appliance outer shell; A support structure includes an upper support frame, a lower support frame, and a fixed base. The upper support frame is used to support the disassembly part, and the lower support frame is used to support the auxiliary disassembly part. The lower support frame is connected to the fixed base. When disassembling the household appliance, the household appliance outer shell is placed on the fixed base.

[0006] As an optimization, an auxiliary component is provided at the lower part of the upper support frame. The auxiliary component includes an opening telescopic rod arranged obliquely upward. The extended end of the opening telescopic rod is configured with a connecting electromagnet for connecting to the upper end of the metal outer layer. When the opening telescopic rod shortens, it pulls the metal outer layer outward and downward to open, enabling the disassembly roller to enter the household appliance shell downward.

[0007] As an optimization, the upper support frame is configured with two first telescopic rods arranged vertically and parallel to each other. The lower end of the first telescopic rod is configured with a connecting seat, and the disassembly roller is rotatably connected to the connecting seat. The connecting seat is configured with a first driving motor for driving the disassembly roller to rotate.

[0008] As an optimization, the outer roller, the inner roller, and the middle roller are coaxially arranged. An adjusting motor is arranged inside the outer roller. The output shaft of the adjusting motor passes through the middle roller and is connected to the axis direction of the inner roller. When the inner roller is locked with the driving section, the driving section rotates relative to the outer roller.

[0009] As an optimization, the middle roller is configured with a locking pin. A plurality of locking electromagnets are arranged inside the inner roller. When the locking electromagnets are powered off, the middle roller and the outer roller are locked by the locking pin. When the locking electromagnets are powered on, the locking electromagnets magnetically attract the locking pin, enabling the inner roller and the middle roller to be locked by the locking pin. A plurality of locking grooves are correspondingly formed in the inner circle of the outer roller and the outer circle of the inner roller for accommodating the locking pin.

[0010] As an optimization, the middle roller is provided with a connecting channel. The diameter of the middle part of the connecting channel increases to form a moving area. The locking pin is slidably arranged in the connecting channel. A limiting ring is arranged outside the locking pin. A supporting spring is arranged inside the moving area, and the limiting ring is connected to the end of the supporting spring far from the inner roller.

[0011] As an optimization, the separating wire is wound around the circumferential direction of the middle roller. When the inner roller drives the middle roller to move towards the connection point of the separating wire and the middle roller, the outer end of the separating wire extends outward through the connecting hole.

[0012] As an optimization, the fixed end of the auxiliary telescopic rod is fixedly connected to the lower support frame, and the connecting disc is an electromagnet or a suction cup.

[0013] As an optimization, the two disassembly rollers are respectively a first disassembly roller and a second disassembly roller. The first disassembly roller travels between the metal outer layer and the filling layer. The second disassembly roller is located above the first disassembly roller and travels between the filling layer and the inner lining.

[0014] As an optimization, before the disassembly device is used, the upper end of the filling layer can be cut to form a guiding inclined surface at the upper end of the filling layer, and a cutting inlet is formed between the guiding inclined surface and the metal outer layer and the inner lining.

[0015] An appliance recycling and disassembly device of this solution has the following advantages: Automated layered disassembly is achieved through the parallelly arranged disassembly rollers (the first disassembly roller separates the metal outer layer from the filling layer, and the second disassembly roller separates the filling layer from the inner lining); the adjustable design for separating the steel wire (controlling the exposed length through the intermediate roller locking mechanism) can adapt to the cleaning requirements of materials with different thicknesses; When the intermediate roller is locked with the inner roller, the separating steel wire can be extended outwards to form a strengthened cleaning part, which can penetrate into the concave areas and stubborn adhesion areas of the appliance shell. The adjustable length structure of the separating steel wire can adapt to the cleaning requirements of appliance shells with different shapes and efficiently separate the filling layer.

[0029] As Figures 1 - 11 shown, an appliance recycling and disassembling device includes a disassembly part for disassembling the metal outer layer 1, filling layer 2 and inner lining 3 of the appliance shell. It includes two parallel disassembly rollers. The disassembly rollers are used to separate the metal outer layer 1 and the filling layer 2, the filling layer 2 and the inner lining 3, and clean the fillers on the metal outer layer 1 and the inner lining 3. The disassembly rollers sequentially include an outer roller 6, an intermediate roller 7 and an inner roller 8 from outside to inside. The intermediate roller 7 includes a plurality of driving sections 9. A plurality of separation wires 10 are uniformly arranged outside the driving sections 9. The outer roller 6 is provided with connection holes, and the separation wires 10 pass through the connection holes and are arranged outside the disassembly rollers. The intermediate roller 7 and the outer roller 6, the inner roller 8 are both lockable structures. When the intermediate roller 7 is locked with the outer roller 6, the exposed length of the separation wires 10 is fixed. When the intermediate roller 7 is locked with the inner roller 8, the intermediate roller 7 is separated from the outer roller 6, and the separation wires 10 can extend outwards to form a strengthened cleaning part; An auxiliary disassembly part is arranged on both sides of the appliance shell and is used to connect the metal outer layer 1 and the inner lining 3 and pull the metal outer layer 1 and the inner lining 3 to separate in opposite directions. It includes an auxiliary telescopic rod 11 and a connection disc 12. The extended end of the auxiliary telescopic rod 11 is connected to the connection disc 12, and the connection disc 12 is adsorbed and connected to the appliance shell; A support structure includes an upper support frame 13, a lower support frame 14 and a fixed base 15. The upper support frame 13 is used to support the disassembly part, and the lower support frame 14 is used to support the auxiliary disassembly part. The lower support frame 14 is connected to the fixed base 15. When disassembling the appliance, the appliance shell is placed on the fixed base 15.

[0030] The outer roller 6, the inner roller 8 and the intermediate roller 7 are coaxially nested components. The outer roller 6 and the intermediate roller 7, the inner roller 8 and the intermediate roller 7 can be arranged in a fitting manner or connected through components such as bearings.

[0031] The disassembled part and the auxiliary disassembled part are supported by a support structure, and the household appliance shell is disassembled from top to bottom by the disassembled part.

[0032] For the shells of different models of refrigerators, freezers, etc., in order to increase the filling amount of the filling layer 2 and improve the fixing effect on the filling layer 2, there may be positions that bulge outwards or sink inwards. When cleaning the filling layer 2 at these positions, the length of the separating wire 10 can be adjusted so that the outer end of the separating wire 10 can contact the connection between the metal outer layer 1 and the filling layer 2, and between the filling layer 2 and the inner lining 3, facilitating the efficient separation and cleaning of the filling layer 2.

[0033] Such as Figure 4 and Figure 5 As shown, an auxiliary component is provided at the lower part of the upper support frame 13. The auxiliary component includes an opening telescopic rod 16 that is inclined upwards. The extended end of the opening telescopic rod 16 is provided with a connecting electromagnet 17. The connecting electromagnet 17 is used to connect the upper end of the metal outer layer 1. When the opening telescopic rod 16 shortens, it pulls the metal outer layer 1 outwards and downwards to open, enabling the disassembly roller to enter the household appliance shell downwards.

[0034] The auxiliary component is used to separate the upper end of the metal outer layer 1 from the filling layer 2, making the metal outer layer 1 tend to move outwards, facilitating the downward movement of the disassembly roller.

[0035] Such as Figure 1 and Figure 12 As shown, the upper support frame 13 is provided with two first telescopic rods 18 arranged vertically in parallel. The lower end of the first telescopic rod 18 is provided with a connecting seat 19. The disassembly roller is rotatably connected to the connecting seat 19; The connecting seat 19 is provided with a first driving motor 20. The first driving motor 20 is used to drive the disassembly roller to rotate.

[0036] The first driving motor 20 is coaxially arranged with the disassembly roller, and the connecting seat 19 is inclined.

[0037] Such as Figure 9 、 Figure 10 and Figure 11 As shown, the outer roller 6, the inner roller 8 and the intermediate roller 7 are coaxially arranged. An adjusting motor 21 is arranged inside the outer roller 6. The output shaft of the adjusting motor 21 passes through the intermediate roller 7 and is connected to the axis direction of the inner roller 8. When the inner roller 8 is locked with the driving section 9, the driving section 9 rotates relative to the outer roller 6.

[0038] Such as Figure 10As shown, the separating wire 10 is wound and stored on the intermediate roller 7, and the outer end of the separating wire 10 extends outside the outer roller 6. When it is necessary to extend the separating wire 10, relative rotation is generated between the intermediate roller 7 and the outer roller 6, and the separating wire 10 can be extended outwards. By reversing, the separating wire 10 can be retracted.

[0039] When the outer roller 6 and the intermediate roller 7 are relatively locked, the length of the separating wire 10 remains unchanged.

[0040] As Figure 11 shown, the intermediate roller 7 is provided with a locking pin 22, and a plurality of locking electromagnets 23 are arranged inside the inner roller 8. When the locking electromagnets 23 are powered off, the intermediate roller 7 and the outer roller 6 are locked by the locking pin 22. When the locking electromagnets 23 are powered on, the locking electromagnets 23 magnetically attract the locking pin 22, so that the inner roller 8 and the intermediate roller 7 are locked by the locking pin 22; A plurality of locking grooves 24 are correspondingly formed in the inner ring of the outer roller 6 and the outer ring of the inner roller 8, and the locking grooves 24 are used for accommodating the locking pin 22.

[0041] The plurality of locking grooves 24 are uniformly arranged along the circumferential direction of the outer roller 6 and the inner roller 8, so that the intermediate roller 7 can be locked and connected to the inner roller 8 and the intermediate roller 7 and the outer roller 6 at any position. When the locking electromagnet 23 is powered off, the locking pin 22 locks the outer roller 6 and the intermediate roller 7. When the locking electromagnet 23 is powered on, the locking pin 22 locks the intermediate roller 7 and the inner roller 8.

[0042] As Figure 11 shown, the intermediate roller 7 is provided with a connecting channel, the middle diameter of the connecting channel is increased to form a moving area, the locking pin 22 is slidably arranged in the connecting channel, a limiting ring 26 is arranged outside the locking pin 22, a support spring 25 is arranged inside the moving area, and the limiting ring 26 is connected to one end of the support spring 25 far away from the inner roller 8.

[0043] When the locking electromagnet 23 is powered off, the support spring 25 pushes the locking pin 22 to pop outwards, and the intermediate roller 7 and the outer roller 6 are locked by the locking pin 22. At this time, the driving sequence is: the first driving motor 20 drives the outer roller 6 to rotate, and the outer roller 6 drives the intermediate roller 7 and the inner roller 8 to rotate through the locking pin 22.

[0044] When the locking electromagnet 23 is powered on, the locking pin 22 moves inwards. At this time, the inner roller 8 can be driven to rotate by the adjusting motor 21, the inner roller 8 drives the intermediate roller 7 to rotate through the locking pin 22, so that the separating wire 10 on the intermediate roller 7 is retracted outwards or inwards. By powering on the locking electromagnet 23 at the corresponding position, the extension length of a part of the separating wire 10 can be adjusted.

[0045] As Figure 10As shown, the separating steel wire 10 is accommodated along the circumferential direction of the middle roller 7. When the inner roller 8 drives the middle roller 7 to move towards the connection point between the separating steel wire 10 and the middle roller 7, the outer end of the separating steel wire 10 extends outwards through the connection hole.

[0046] The length that the separating steel wire 10 needs to be adjusted is the outer circumference length of the middle roller 7 corresponding to the running angle of the adjusting motor 21.

[0047] As Figure 1 shown, the fixed end of the auxiliary telescopic rod 11 is fixedly connected to the lower support frame 14, and the connecting disc 12 is an electromagnet or a suction cup.

[0048] Generally, the outer shell of household appliances is mostly made of metal material, and the connecting disc 12 can use an electromagnet. When the outer shell of the household appliance cannot be magnetically attracted, the connecting disc 12 can be an electric suction cup. The electric suction cup is connected to the smooth position of the outer shell of the household appliance, and the auxiliary telescopic rod 11 is shortened, so that the metal outer layer 1 and the inner lining 3 of the outer shell of the household appliance can be pulled in opposite directions to help separate the metal outer layer 1 and the inner lining 3.

[0049] As Figure 7 described, the two disassembling rollers are respectively a first disassembling roller 4 and a second disassembling roller 5. The first disassembling roller 4 travels between the metal outer layer 1 and the filling layer 2, and the second disassembling roller 5 is located above the first disassembling roller 4. The second disassembling roller 5 travels between the filling layer 2 and the inner lining 3.

[0050] As Figure 12 shown, before the disassembling device is used, the upper end of the filling layer 2 can be cut to form a guiding inclined surface 27 at the upper end of the filling layer 2. The guiding inclined surface 27 forms a cutting inlet between the metal outer layer 1 and the inner lining 3.

[0051] According to the structural characteristics of household appliances, when the outer layer or the inner layer of the outer shell of household appliances is an uneven layer, the disassembling roller of the present application can be used for disassembly. When the outer layer of the outer shell of the household appliance is an uneven layer and the inner layer is a flat layer, the disassembling roller used to separate the inner layer and the filling layer 2 can be a disassembling roller with a common and non-adjustable length of the separating steel wire 10.

[0052] Usage method: When the device is specifically used, first, a household appliance with a three-layer structure such as a refrigerator or a freezer is simply disassembled into multiple independent outer shells of household appliances, and the outer shells of household appliances have no edges sealed, so that the disassembling roller can enter the inside of the outer shell of the household appliance; Place the outer shell of the household appliance on the fixed base 15. By extending the auxiliary telescopic rod 11, the connecting disc 12 is connected to the metal outer layer 1 and the inner lining 3 of the outer shell of the household appliance to fix the outer shell of the household appliance, so that the first disassembling roller 4 and the second disassembling roller 5 are located directly above the outer shell of the household appliance; Cut the filling layer 2 at the upper end to form a guiding inclined surface 27, which facilitates the disassembly roller to enter the household appliance shell. According to the actual operation situation, this step can also be omitted. The telescopic rod 16 of the opening is extended, and the connecting electromagnet 17 is energized to magnetically connect the connecting electromagnet 17 with the metal outer layer 1. The telescopic rod of the opening is shortened, so that the connecting electromagnet 17 pulls the upper end of the metal outer layer 1 outward and downward to facilitate the first disassembly roller 4 to move downward along the filling layer 2 and disassemble the filling layer 2 and the metal outer layer 1. According to the size and shape of the household appliance shell, set the control program of the disassembly device so that when the disassembly roller moves to an uneven position of the household appliance shell, the length of the separation wire 10 at this position is adjusted correspondingly, so that the outer end of the separation wire 10 can always contact the outer edge of the filling layer 2, promoting the efficient separation and cleaning of the filling layer 2. Drive the first disassembly roller 4 and the second disassembly roller 5 to move downward through the first telescopic rod 18. The first disassembly roller 4 first disassembles the filling layer 2. The second disassembly roller 5 is located at the rear side of the advancing direction of the first disassembly roller 4. At the same time, the auxiliary telescopic rod 11 adjacent to the position where the disassembly roller is located is shortened, and the auxiliary disassembly part is used to pull and separate the metal outer layer 1 from the filling layer 2 and between the filling layer 2 and the inner lining 3, ensuring the separation speed and promoting the downward movement of the disassembly roller. When the first disassembly roller 4 moves downward, drive the first disassembly roller 4 to rotate through the first driving motor 20, and separate and clean the connection between the filling layer 2 and the metal outer layer 1 through the separation wire 10. When the length of the cleaning wire needs to be adjusted, the locking electromagnet 23 at the adjustment position is energized through the controller. The locking electromagnet 23 magnetically attracts the locking pin 22 at this position, so that the inner roller 8 and the middle roller 7 at this position are locked, and the middle roller 7 and the outer roller 6 at this position are separated. At this time, drive the inner roller 8 to rotate through the adjustment motor 21, and the inner roller 8 drives the driving section 9 at this position to rotate. Due to the position change between the driving section 9 and the outer roller 6, the separation wire 10 at this position will be released outward or retracted inward. According to the concave and convex depth of the uneven position, just rotate the adjustment motor 21 by a corresponding angle to realize the corresponding adjustment of the length of the separation wire 10.

[0053] The above specific implementation manners are only specific cases of the present invention. The patent protection scope of the present invention includes but is not limited to the product forms and styles of the above specific implementation manners. Any household appliance recycling and disassembly device that meets the claims of the present invention and any appropriate changes or modifications made by those of ordinary skill in the relevant technical fields shall fall within the patent protection scope of the present invention.
