[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.
[0025] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.
[0026] like Figures 1 to 5 As shown, this utility model provides an auxiliary device for aligning the loading and unloading of copper powder mixing tanks. The device includes a workbench 1, which is a two-story steel structure. A material storage tank is located at the top of the workbench 1. A discharge pipe 11 connects to the material storage tank and extends to the top of the workbench 1. A through hole is opened on the upper layer of the workbench 1, and the discharge pipe 11 is aligned with the through hole. A flexible hose is located below the discharge pipe 11. A material transfer device is located below the workbench 1. A receiving pipe 12 connects to the material transfer device and extends to the bottom layer of the workbench 1. A through hole is also opened on the bottom layer of the workbench 1, and the receiving pipe 12 connects to... The rotary mixer 2, an existing industrial mixer, is equipped with a flexible hose on the receiving pipe 12. It achieves material mixing by rotating around an axis. The rotary mixer 2 is located in the middle layer of the workbench 1. The rotary mixer 2 is equipped with a receiving port 21. The rotary mixer 2 is installed on the rotation axis, and the receiving port 21 can be aligned upward with the discharge pipe 11. When connected with the discharge pipe 11, the material can be transported into the rotary mixer through the material storage tank. When aligned downward with the receiving pipe 12, the material in the mixing tank can be discharged into the material transfer equipment.
[0027] The auxiliary rotary mixer 2 is connected to the receiving port 21. An upper docking device 3 is installed below the discharge pipe 11. The upper docking device 3 includes a sliding device 31, docking cylinders 32, an alignment platform 33, an ear seat 34, a docking pipe 35, an upper top connector 36, and a lower top connector 37. The sliding device 31 is installed at the top of the middle layer of the workbench 1 and is located below the discharge pipe 11. The sliding direction of the sliding device 31 is consistent with the rotation direction of the rotary mixer 2. Below the sliding device 31, there are four vertically downward docking cylinders 32, arranged symmetrically in pairs. Below the docking cylinders 32, there is an alignment platform 33, which is a rectangular plate parallel to the sliding device 31. The alignment platform 33 has... There are four ear seats 34, which are hinged to four docking cylinders 32 respectively. A docking pipe 35 is set in the middle of the alignment platform 33. The docking pipe 35 passes through the alignment platform 33 and its upper end is connected to a hose. An upper docking connector 36 is set below the docking platform. The upper connector is an inverted cone shape with the opening facing downward. The upper docking connector 36 is coaxial with the docking pipe 35 and is connected to the bottom surface of the docking pipe 35. A lower docking connector 37 is set at the material inlet 21 of the rotary mixer 2. The lower docking connector 37 is a positive cone shape that cooperates with the upper docking connector 36. The lower docking connector 37 is inserted into the upper docking connector 36. The outer cone surface of the lower docking connector 37 is in contact with the inner cone surface of the upper docking connector 36.
[0028] In the first working state, the material needs to be introduced from the material storage tank into the rotary mixer 2 by connecting with the discharge pipe 11. The rotary mixer 2 rotates to face the receiving port 21, aligning or bringing the receiving port 21 close to the discharge pipe 11. When there is a deviation between the position of the receiving port 21 and the discharge pipe 11, but the receiving port 21 is still close to the discharge pipe 11, the docking cylinder 32 is driven to lower the alignment platform 33 and the upper top connector 36. As the upper top connector 36 descends, it will gradually abut against the lower top connector. During the docking process, the upper top connector 36 and the lower top connector... The contact guidance of the mating conical surfaces 37: The upper mating connector 36 continuously descends via the docking cylinder 32. Under the action of the conical surface friction, the sliding device 31 will translate and adjust its position. The direction of displacement is determined by the direction the lower mating connector tilts. Because the conical structure of the upper and lower mating connectors 37 is mated, the conical surfaces of the two connectors are forced to fit together. Therefore, driven by the docking cylinder 32, the docking platform will tilt and adjust its position, so that the conical surfaces of the upper and lower mating connectors 36 and 37 are completely fitted together. After docking is completed (37), the receiving port 21 is coaxial and aligned with the connecting pipe 35. The lower end face of the connecting pipe 35 is parallel to the top face of the upper connecting joint 36, and the top face of the receiving port 21 is parallel to the top face of the lower connecting joint 37. When the upper connecting joint 36 and the lower connecting joint 37 are completed, the receiving pipe 12 and the receiving port 21 are in abutting and fitting state. Through the conical contact design of the upper connecting joint 36 and the lower connecting joint 37, this invention automatically guides the receiving port 21 to align with the axis of the connecting pipe 35 during the docking process. Simultaneously, the sliding device 31 moves along the rotary mixer 2... The rotation direction slides to compensate for radial position deviation. Combined with the docking cylinder 32 driving the alignment platform 33 to deflect around the hinge point of the ear seat 34 to adaptively adjust the angle of the docking pipe 35, the material receiving port 21 and the docking pipe 35 can be accurately closed under radial and angular deviations. Through the progressive single-sided abutment closure method, damage to the sealing surface caused by hard collision is avoided, and reliable sealing after docking is ensured. This solves the problem that the traditional vertical docking method cannot adapt to the dynamic deviation of the rotary mixer, significantly improves the fault tolerance and operating efficiency of loading and unloading alignment, and simplifies the structural design and extends the service life of the components.
[0029] To ensure the stability and sealing of the connection, a positioning groove 361 is provided in the upper top joint 36, and a positioning ring 371 is provided on the lower top joint 37. The positioning groove 361 and the positioning ring 371 can improve the stability of the connection and also play a sealing role to prevent material leakage.
[0030] To ensure that the upper docking joint 36 can return to its original position after loading and await the next docking, the sliding device 31 includes a track platform 331, a sliding track 332, a reset component 333, a guide slider 334, and a support platform 335. The track platform 331 is fixedly connected to the worktable 1. The sliding track 332 is disposed on the track platform 331. The reset component is disposed within the sliding track 332. The guide slider 334 is disposed within the sliding track 332 and connected to the reset component. The support platform 335 is connected to the guide slider 334 and the docking cylinder 32. The reset component 333 includes... The system includes a drive screw 3331 and a reset motor 3332. The drive screw 3331 is located within the sliding track 332. The guide slider 334 is connected to the drive screw 3331 via a nut. The reset motor 3332 is connected to the drive screw 3331. The reset motor 3332 drives the screw to rotate, thereby resetting the guide slider 334. This, in turn, resets the support platform 335, the alignment platform 33, and the upper alignment joint 36. During the reset process, because the weight of the alignment platform 33 and the docking cylinder 32 are synchronously retracted to the same height, the alignment platform 33 synchronously resets to a state parallel to the support platform 335.
[0031] In the second working state, the rotary mixer 2 needs to be aligned with the receiving pipe 12 to discharge the material into the material transfer equipment. The rotary mixer 2 rotates to face the receiving port 21 downwards, aligning or bringing the receiving port 21 close to the receiving pipe 12. When there is a deviation between the position of the receiving port and the discharge pipe 11, the lower docking device 4 installed above the receiving pipe 12 has the same structure as the upper docking device 3, and the principle of the auxiliary alignment step is also the same. The discharge pipe 11 is located above the receiving port 21, and the docking pipe 35 is also located above the receiving port 21. At this time, the receiving port 21 needs to extend downwards to meet the material discharge pipe 12. The receiving pipe 12 is located below the receiving hole, and the connecting pipe 35 is also located below the receiving port 21. All receiving pipes 12 need to be raised to connect with the receiving hole. Therefore, the opening of the upper connecting joint 36 in the lower connecting device 4 needs to be set upward, and the connecting cylinder 32 needs to pull the alignment platform 33 upward. The same principle as the upper connecting device is used to complete the connection between the receiving pipe 12 and the receiving port 21, so as to realize the unloading of materials. It should be noted that the lower connecting device 4 and the upper connecting device 3 have the same structure and the same alignment principle. This application will not explain further, and the reference numerals in the attached drawings are the same as those in the upper connecting device 3.
[0032] To determine whether the upper and lower top connectors 36 and 37 have completed docking, and thus control the docking cylinder 32, the system uses first sensors 5 on both sides of the positioning groove 361 to detect and automatically adjust the docking status. When the lower top connector 37 tilts, the higher side positioning ring 371 enters the positioning groove 361 first, triggering the sensor on that side. The PLC control system immediately stops driving the higher side docking cylinder 32, while maintaining the lower side cylinder's continuous advancement. The tilt angle of the alignment platform 33 is gradually corrected through differential speed adjustment. When both side positioning rings 371 are simultaneously embedded in the positioning groove 361 (indicating that the upper and lower connectors have completed coaxial alignment), both side sensors simultaneously send a positioning signal. The PLC will simultaneously cut off the power to both side cylinders, ensuring accurate completion of the docking process and avoiding mechanical interference.
[0033] To ensure a full circumferential seal between the connecting pipe 35 and the receiving port 21, two sets of proximity switch-type second sensors 6 are symmetrically deployed at the bottom of the connecting pipe 35, forming a dual verification mechanism: During the vertical docking stage, when both sensors simultaneously detect that the metal surface of the receiving port 21 has entered the preset sensing distance (typical value 2-5mm), the PLC industrial control system will receive dual-path positioning signals and determine that the connection is complete; During the abnormal monitoring stage, if a sensor on one side fails to trigger (possibly due to pipe misalignment or mechanical jamming) or if there is a time difference of more than 100ms between the signals on both sides (possibly caused by tilted docking), the PLC industrial control system will immediately activate the audible and visual alarm device, synchronously interrupt the cylinder drive and push a fault code. The operator can locate the abnormal side in real time through the HMI interface and start the correction program.
[0034] Furthermore, the rotary mixer 2 provides a stable load-bearing foundation through the support frames symmetrically installed on the workbench 1. The rotation shaft between the two side support frames and the mixing drum achieves suspended drum support. The coordinated action of the geared motor and the encoder enables precise control of the stopping position of the rotary mixing drum: the geared motor provides smooth power buffer for the stopping process by adjusting the output speed and torque, effectively suppressing the displacement deviation caused by the inertia of the equipment; the encoder tracks the rotation angle of the mixing drum in real time and feeds back the position information to the control system, forming a closed-loop adjustment mechanism to ensure that the discharge port or specific functional position of the mixing drum is accurately aligned with the preset angle each time the machine stops. It should be noted that the rotary mixer 2 is existing technology and equipment. Its rotary mixing and control of the stopping position of the mixing drum are existing mature technologies, and this application will not further describe them.
