Description

Technical Field

[0001] This utility model relates to the technical field of washing machine disassembly equipment, and in particular to a rapid separation device for the inner drum of a waste washing machine. Background Technology

[0002] In the field of waste household appliance recycling, washing machines, as a common category, require a crucial step in subsequent resource utilization by separating their outer shell from the inner drum. The inner drum is typically fixed to the outer shell by multiple connectors, and its surface may be covered with dirt and rust, making separation difficult. Currently, the separation of the inner drum in waste washing machines is mostly done manually using simple tools (such as pry bars and hammers) or with simple semi-automatic equipment. On the one hand, manual disassembly is extremely inefficient and labor-intensive, making it difficult to meet the needs of large-scale recycling. On the other hand, existing semi-automatic equipment generally suffers from unstable clamping mechanisms, which are prone to displacement when clamping the washing machine shell, leading to deviations in the subsequent inner drum disassembly position. This not only affects the separation effect but may also cause excessive damage to the shell or inner drum, reducing the resource recycling rate. These two major problems severely restrict the industrialization process of waste washing machine recycling. Therefore, we propose a rapid separation device for the inner drum of waste washing machines. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a rapid separation device for the inner drum of a used washing machine.

[0004] This utility model solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a quick separation device for the inner drum of a waste washing machine, including a support base. The top of the support base has a rectangular groove, and two movable blocks are movably engaged in the rectangular groove. The two movable blocks are correspondingly screwed onto a bidirectional lead screw. A connecting block is installed on the inner side of the movable block by connecting bolts. A clamping seat is provided on the inner side of the connecting block. A hydraulic cylinder is provided on the outer side of the support base. A top plate is connected to the top of the hydraulic cylinder. An outer drum is installed below the top plate. A disc is provided at the bottom of the outer drum. Multiple movable grooves are equidistantly opened on the edge of the disc. A splitting block is movably engaged in the movable groove. A wear-resistant block is installed in the groove on the outer side of the splitting block. One end of the splitting block is fixedly connected to a threaded sleeve by a pull rod. The threaded sleeve is connected to a synchronous drive mechanism.

[0006] In the above scheme, a base is provided at the bottom of the support seat, and the bottom of the hydraulic cylinder is fixed on the base.

[0007] In the above scheme, one end of the bidirectional lead screw passes through the side wall of the support base and is connected to the first motor for transmission.

[0008] In the above scheme, the bottom of the clamping seat is movably abutted against the upper surface of the support seat, and a receiving groove is provided on the inner side of the clamping seat.

[0009] In the above scheme, the synchronous drive mechanism includes multiple screws rotatably installed in the inner cylinder, the screws are screwed into the inner screw of the screw sleeve, the other end of the screw is connected to a first bevel gear, the multiple first bevel gears mesh at equal distances with the side of a second bevel gear, and the top of the second bevel gear is connected to a second motor through a transmission shaft.

[0010] In the above scheme, the outer cylinder is fixed to the bottom of the top plate by connecting plates and screws.

[0011] In the above scheme, anti-slip textures are provided on both the inner and outer sides of the splitting block.

[0012] The advantages and beneficial effects of this utility model are as follows: This utility model provides a quick separation device for the inner drum of a waste washing machine. By setting two clamping seats above the support base as clamping components, when the first motor drives the bidirectional lead screw to rotate, it drives the two moving blocks to move in the rectangular groove, thereby making the two clamping seats move closer and closer to clamp and fix the washing machine shell to be disassembled. Then, the hydraulic cylinder can drive the top plate and the splitting mechanism to move down, so that the splitting block contacts the inner drum of the washing machine. At this time, under the drive of the second motor, the second bevel gear drives the first bevel gear to rotate. When the first bevel gear rotates, it drives the screw sleeve to move relative to it through the screw rod, thereby driving the splitting block to move closer or further away through the pull rod. With the cooperation of the above mechanism, the disassembly effect of the inner drum is achieved. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figure 1-3 As shown, this utility model is a quick separation device for the inner drum of a waste washing machine, including a support base 11. The top of the support base 11 has a rectangular groove 12, and two moving blocks 13 are movably engaged in the rectangular groove 12. The two moving blocks 13 are correspondingly screwed onto a bidirectional lead screw 14. A connecting block 16 is installed on the inner side of the moving block 13 through a connecting bolt 18. A clamping seat 17 is provided on the inner side of the connecting block 16. A hydraulic cylinder 19 is provided on the outer side of the support base 11. A top plate 2 is connected to the top of the hydraulic cylinder 19. An outer drum 22 is installed below the top plate 2. A disc 26 is provided at the bottom of the outer drum 22. Multiple movable grooves 24 are equidistantly opened on the edge of the disc 26. A splitting block 23 is movably engaged in the movable groove 24. A wear-resistant block 25 is installed in the groove on the outer side of the splitting block 23. One end of the splitting block 23 is fixedly connected to a threaded sleeve 28 through a pull rod 27. The threaded sleeve 28 is connected to a synchronous drive mechanism.

[0020] The support base 11 is the basic load-bearing component of the device. The rectangular groove 12 provides a guide for the movement of the moving block 13, ensuring that the moving block 13 can only move horizontally along the rectangular groove 12. The positive and negative thread design of the bidirectional lead screw 14 can realize the synchronous approach or departure of the two moving blocks 13. The connecting bolt 18 facilitates the disassembly and assembly of the connecting block 16 and the moving block 13, and facilitates the subsequent maintenance or replacement of the clamping base 17. The outer cylinder 22 provides installation protection space for the synchronous drive mechanism. The movable groove 24 on the disc 26 plays a limiting role for the splitting block 23, preventing the splitting block 23 from deviating from the trajectory during movement. The wear-resistant block 25 can enhance the wear resistance of the contact part between the splitting block 23 and the inner cylinder, and extend the service life of the splitting block 23. The pull rod 27 realizes the power transmission between the splitting block 23 and the screw sleeve 28, and the synchronous drive mechanism provides power for the synchronous movement of multiple splitting blocks 23. By combining the support base 11, rectangular groove 12, moving block 13, bidirectional lead screw 14, connecting bolt 18, connecting block 16, clamping base 17, hydraulic cylinder 19, top plate 2, outer drum 22, disc 26, movable groove 24, splitting block 23, wear-resistant block 25, pull rod 27, screw sleeve 28, and synchronous drive mechanism into a complete inner drum separation device integrating clamping, lifting, and dismantling, the device solves the problem of fragmented functions and the need for multiple devices to operate in existing equipment. It provides an integrated solution for the rapid separation of inner drums of waste washing machines and improves the continuity of operation.

[0021] In the above scheme, a base 1 is provided at the bottom of the support 11, and the bottom of the hydraulic cylinder 19 is fixed on the base 1. The base 1 is made of high-strength metal material, and its area is larger than the bottom area of ​​the support 11, which can increase the contact area between the device and the ground; the bottom of the hydraulic cylinder 19 is fixed to the base 1 by bolts to ensure that the hydraulic cylinder 19 will not shift its position during the extension and retraction process.

[0022] In the above scheme, one end of the bidirectional lead screw 14 passes through the side wall of the support base 11 and is connected to the first motor 15 for transmission. The first motor 15 is a servo motor, which can realize forward and reverse rotation control. Its output shaft is fixedly connected to the bidirectional lead screw 14 through a coupling, which can accurately transmit the rotational power of the motor to the bidirectional lead screw 14, driving the bidirectional lead screw 14 to rotate stably.

[0023] In the above scheme, the bottom of the clamping seat 17 movably abuts against the upper surface of the support seat 11, and a receiving groove is provided on the inner side of the clamping seat 17. The movable abutment between the bottom of the clamping seat 17 and the upper surface of the support seat 11 can reduce the frictional resistance when the clamping seat 17 moves. At the same time, the support seat 11 provides vertical support for the clamping seat 17, preventing the clamping seat 17 from sagging due to force during clamping. The receiving groove on the inner side of the clamping seat 17 can be used to place the bottom edge of the washing machine shell, which provides initial positioning of the shell and facilitates the subsequent precise clamping of the shell by the clamping seat 17.

[0024] In the above scheme, the synchronous drive mechanism includes multiple screws 29 rotatably installed in the inner cylinder 33. The screws 29 are screwed into the inner sleeve 28. The other end of each screw 29 is connected to a first bevel gear 3. Multiple first bevel gears 3 mesh equidistantly with the sides of a second bevel gear 31. The top of the second bevel gear 31 is connected to a second motor 32 via a transmission shaft. The cylinder 33 is fixed inside the outer cylinder 22, providing installation space for the screws 29, first bevel gears 3, and second bevel gears 31. The screwed engagement between the screws 29 and the sleeve 28 converts the rotational motion of the screws 29 into the linear motion of the sleeve 28. The equidistant meshing of the first bevel gears 3 with the sides of the second bevel gear 31 ensures that the rotation of the second bevel gear 31 simultaneously drives all the first bevel gears 3 to rotate synchronously, thereby achieving synchronous rotation of the multiple screws 29. The second motor 32 is also a servo motor, which can precisely control the speed and direction, providing stable power to the synchronous drive mechanism.

[0025] In the above scheme, the outer cylinder 22 is fixed to the bottom of the top plate 2 by connecting plates and screws. The connecting plates are made of metal and are fixed to the top of the outer cylinder 22 and the lower surface of the top plate 2 by screws. The screw connection method facilitates the disassembly and assembly of the outer cylinder 22. When the internal components of the outer cylinder 22 malfunction, the outer cylinder 22 can be quickly disassembled for maintenance.

[0026] In the above solution, anti-slip textures are provided on both the inner and outer sides of the splitting block 23. The anti-slip textures on the inner side of the splitting block 23 are used to enhance the friction between the splitting block 23 and the surface of the washing machine inner drum, while the anti-slip textures on the outer side can reduce the sliding displacement of the splitting block 23 in the movable groove 24 when the splitting block 23 contacts the inner wall of the movable groove 24, ensuring the accurate movement direction of the splitting block 23.

[0027] Working principle:

[0028] This type of waste washing machine inner drum quick separation device first places the waste washing machine shell to be separated on the support base 11, so that the bottom edge of the washing machine shell is embedded in the receiving groove inside the clamping base 17. The receiving groove initially limits the shell, ensuring that the shell is placed accurately, laying the foundation for subsequent clamping operations.

[0029] The first motor 15 is started, and the output shaft of the first motor 15 drives the bidirectional lead screw 14 to rotate through the coupling. Since the two moving blocks 13 are screwed onto the positive and negative thread sections of the bidirectional lead screw 14, and the moving blocks 13 are movably engaged in the rectangular groove 12, when the bidirectional lead screw 14 rotates, it drives the two moving blocks 13 to move inward synchronously along the rectangular groove 12. The connecting block 16 connected to the moving blocks 13 through the connecting bolt 18 moves synchronously, thereby driving the clamping seat 17 on the inner side of the connecting block 16 to move closer to the washing machine shell, until the two clamping seats 17 are tightly abutted against both sides of the washing machine shell, thus achieving a firm clamping and fixing of the washing machine shell and preventing the shell from shifting during subsequent disassembly.

[0030] Start the hydraulic cylinder 19, extend the piston rod of the hydraulic cylinder 19, and drive the top plate 2 to move vertically downward; the outer cylinder 22, which is fixed below the top plate 2 by the connecting plate and screws, moves down synchronously with the top plate 2, and the disc 26 at the bottom of the outer cylinder 22 and the splitting block 23 on the disc 26 also move down synchronously; continue to move down until the inner side of the splitting block 23 contacts the outer surface of the washing machine inner drum, at which point the hydraulic cylinder 19 is closed, and the docking of the splitting mechanism with the inner drum is completed;

[0031] The second motor 32 is started, and its output shaft drives the second bevel gear 31 to rotate via a transmission shaft. Since multiple first bevel gears 3 mesh equally at the side of the second bevel gear 31, the rotation of the second bevel gear 31 synchronously drives all the first bevel gears 3 to rotate. The end of each first bevel gear 3 furthest from the second bevel gear 31 is fixedly connected to the screw 29, thereby driving the screw 29 to rotate synchronously. The screw sleeve 28 is screwed onto the screw 29, and is fixedly connected to the splitting block 23 via a pull rod 27. When the screw 29 rotates, the screw sleeve 28 moves along the screw 29 towards the inside. The cylinder moves in the direction of movement; the screw sleeve 28 drives the splitting block 23 to move synchronously inward in the movable groove 24 via the pull rod 27. The anti-slip texture on the inner side of the splitting block 23 enhances the friction with the surface of the inner cylinder to prevent slippage. At the same time, the splitting block 23 applies a force to the inner cylinder in the opposite direction. As the splitting block 23 continues to move inward, the connecting parts between the inner cylinder and the outer shell are gradually broken, and finally the inner cylinder and the outer shell are separated. If it is necessary to adjust the splitting force or position, the speed and direction of movement of the splitting block 23 can be adjusted by controlling the speed and direction of the second motor 32 to ensure that the dismantling process is controllable.

[0032] After the inner drum is separated, the second motor 32 is first reversed, which drives the screw 29 to reverse, so that the screw sleeve 28 drives the splitting block 23 to move outward along the movable groove 24 to reset. Then, the piston rod of the hydraulic cylinder 19 is controlled to retract, which drives the top plate 2 and the splitting mechanism to move upward to reset. Finally, the first motor 15 is controlled to reverse, which drives the bidirectional lead screw 14 to reverse, so that the two moving blocks 13 drive the clamping seat 17 to move outward, releasing the clamping of the washing machine shell. At this time, the separated inner drum and outer shell can be removed from the support seat 11 to complete one waste washing machine inner drum separation operation.
