Description

Technical Field

[0001] This invention relates to the field of thermos cup polishing technology, and more specifically, to an automated device for simultaneous polishing of the inner and outer walls of a thermos cup. Background Technology

[0002] In the manufacturing process of stainless steel thermos cups, polishing of the inner and outer walls is a crucial step to ensure their appearance quality and performance. Because stainless steel has high hardness, surface roughness directly affects the product's aesthetics and corrosion resistance; therefore, meticulous polishing is necessary.

[0003] Traditional polishing processes often rely on manual operation or semi-automatic equipment, resulting in low efficiency, high labor intensity, and poor polishing consistency. This makes it difficult to meet the dual demands of modern industry for product quality and production efficiency. Furthermore, although some automated polishing equipment has entered the market in recent years, achieving a transition from manual to mechanized processes, most of these devices can only polish the outer or inner wall of the thermos cup in a single direction. For stainless steel thermos cups requiring high-quality surface treatment of both the inner and outer walls simultaneously, existing equipment often necessitates multiple clamping and separate processing of the workpiece, increasing the complexity of the process, extending the processing cycle, and reducing overall production efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

The connecting block is connected to the moving plate. The second hinge rod is hinged to the first hinge rod. A limit rod is connected to the top of the threaded sleeve.

[0008] Furthermore, in order to drive the mounting base to rotate, the drive mechanism includes a mounting bracket located at the top of the sliding frame, a drive shaft connected to the mounting bracket via bearings, the drive shaft connected to a rotating shaft via a belt drive system, the rotating shaft connected to a first drive motor, the rotating shaft connected to the mounting bracket via bearings, and the drive shaft connected to the mounting base.

[0009] Furthermore, the belt drive system includes a first pulley located outside the drive shaft, a second pulley located above the first pulley, the first pulley and the second pulley being connected by a belt drive, and the second pulley being connected to the rotating shaft.

[0010] Furthermore, in order to clamp and fix the bottom of the thermos cup, the clamping mechanism includes a fixed frame located on one side of the polishing table. A chuck is rotatably connected to one side of the fixed frame via a fixed shaft. One end of the fixed shaft is connected to the output end of the reducer. The reducer is connected to the output end of the second drive motor via a belt drive system. The second drive motor is located inside the fixed frame.

[0011] Furthermore, the outer wall polishing mechanism includes a threaded rod located at the top of the support frame. Both sides of the threaded rod are connected to a fixed block via bearings. The fixed block is connected to the support frame. A sliding seat is threaded onto the threaded rod. A second hydraulic telescopic rod is connected to the top of the sliding seat. The output end of the second hydraulic telescopic rod is connected to the fixed seat. A polishing motor is fixedly connected to one side of the fixed seat. The output end of the polishing motor is connected to a polishing shaft via a belt drive system. The polishing shaft is connected to the fixed seat via bearings. One end of the polishing shaft is connected to the outer wall polishing wheel. One end of the threaded rod passes through the fixed block and is connected to a servo motor.

[0012] Furthermore, a sliding groove is located at the top of the placement groove, which is fixed on the polishing table. A third hydraulic telescopic rod is fixed inside the placement groove. The output end of the third hydraulic telescopic rod is connected to the moving block. A third hinge rod is hinged to both sides of the moving block.

[0014] Furthermore, a control system is installed at the bottom of the polishing table.

[0015] The beneficial effects of this invention are as follows:

[0016] (1) By setting an inner wall polishing mechanism and a clamping mechanism on both sides of the polishing table, and setting an outer wall polishing mechanism on the top of the support frame, the polishing operation of the inner and outer walls of the thermos cup can be completed simultaneously in one clamping process, avoiding the efficiency loss caused by multiple clamping and changing of workstations in the traditional process. This greatly shortens the processing cycle and improves the overall production efficiency. In addition, the inner wall polishing mechanism uses a first hydraulic telescopic rod to drive the sliding frame to move along the sliding groove, combined with the rotary motor driving the screw to rotate, and pushes the inner wall polishing wheel to unfold or retract through the linkage structure of the threaded sleeve and the hinge rod, which can automatically adapt to the inner wall size of thermos cups of different diameters. This structure not only improves the versatility of the equipment, but also ensures a good fit between the polishing wheel and the inner wall of the cup, improving the polishing accuracy and consistency.

[0017] (2) By setting up a third hydraulic telescopic rod, a limiting roller and other auxiliary support structures inside the placement slot, a stable support force is provided for the side wall of the thermos cup, which helps the clamping mechanism to achieve a more stable positioning. At the same time, the dust removal system composed of the adsorption tank and the exhaust fan can remove the metal dust generated during the polishing process in a timely manner through the adsorption holes, avoid dust diffusion, improve the working environment and protect the health of the operators.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] According to an embodiment of the present invention, an automated device for simultaneous polishing of the inner and outer walls of a thermos cup is provided.

[0031] Example 1

[0032] like Figures 1-8As shown, the automated device for simultaneous polishing of the inner and outer walls of a thermos cup according to an embodiment of the present invention includes a polishing table 1, a support frame 2 connected above the polishing table 1, a clamping mechanism 3 on one side of the polishing table 1, an inner wall polishing mechanism 4 on the other side of the polishing table 1, an outer wall polishing mechanism 5 at the top of the support frame 2, and a control system 22 at the bottom of the polishing table 1. The control system uses a PLC controller as the core control unit and integrates a human-machine interface (HMI), sensor modules, actuator drive modules, etc., to achieve intelligent control of the entire machine's operation. The inner wall polishing mechanism 4 includes a sliding groove 413 located on one side of the polishing table 1. A sliding frame 412 is slidably connected inside the sliding groove 413 and can slide back and forth within the sliding groove 413. A first hydraulic telescopic rod 414 is located on one side of the sliding groove 413 and is connected to the sliding frame 412, used to drive the entire inner wall polishing assembly closer to or away from the workpiece. A drive mechanism 6 is connected to the top of the sliding frame 412, and the output end of the drive mechanism 6 is connected to a mounting base 410. A rotary motor 411 is located inside the mounting base 410. One end of the screw 401 is connected to the screw rod 401, which is connected to the mounting base 410 via a bearing. A threaded sleeve 402 is threadedly connected to the outside of the screw rod 401. A first hinge rod 403 is connected to the outside of the threaded sleeve 402 via a hinge seat. The first hinge rod 403 is hinged to the movable plate 404. An inner wall polishing wheel 409 is connected to the outside of the movable plate 404. One end of the screw 401 is rotatably connected to a connecting sleeve 405 via a bearing. The outside of the connecting sleeve 405 is hinged to a second hinge rod 406. The other end of the second hinge rod 406 is connected to the connecting block 40 via a connecting rod 407. 8. A sliding connection is established, with connecting block 408 connected to moving plate 404. The second hinge rod 406 is hinged to the first hinge rod 403. A limit rod 415 is connected to the top of threaded sleeve 402. The limit rod 415 is embedded in the limit groove 416 inside mounting base 410, ensuring that threaded sleeve 402 can only move in a straight line. The screw 401 is long enough to not interfere with the normal movement of outer wall polishing wheel 508 during the movement of the first drive motor 604. The drive mechanism 6 includes a mounting bracket 601 located at the top of sliding frame 412. The mounting bracket 601 is connected to the sliding frame 412 via bearings. A drive shaft 602 is connected to a rotating shaft 603 via a belt drive system 7. The rotating shaft 603 is connected to a first drive motor 604 and a mounting bracket 601 via a bearing. The drive shaft 602 is connected to a mounting base 410. The belt drive system 7 includes a first pulley 701 located outside the drive shaft 602 and a second pulley 702 located above the first pulley 701. The first pulley 701 and the second pulley 702 are connected by a belt drive. The second pulley 702 is connected to the rotating shaft 603.When the rotary motor 411 starts, the screw 401 rotates, driving the threaded sleeve 402 to move axially. Then, through the linkage mechanism composed of the first hinge rod 403 and the second hinge rod 406, the inner wall polishing wheel 409 is pushed to expand or contract, so as to achieve adaptive fitting polishing of the inner wall of thermos cups of different diameters.

[0033] like Figures 1-5 As shown, the clamping mechanism 3 includes a fixed frame 301 located on one side of the polishing table 1. A chuck 302 is rotatably connected to one side of the fixed frame 301 via a fixed shaft. One end of the fixed shaft is connected to the output end of a reducer 303. The reducer 303 is connected to the output end of a second drive motor 304 via a belt drive system. The second drive motor 304 is located inside the fixed frame 301. When the second drive motor 304 starts, power is transmitted to the chuck 302 via the reducer 303, causing it to rotate and clamp or release the bottom of the thermos cup. This structure can stably clamp thermos cups of different sizes, preventing them from shifting or falling off during the polishing process.

[0034] like Figure 8 As shown, the outer wall polishing mechanism 5 includes a threaded rod 501 located at the top of the support frame 2. Both sides of the threaded rod 501 are connected to a fixed block 502 via bearings. The fixed block 502 is connected to the support frame 2. A sliding seat 503 is threaded onto the threaded rod 501. A second hydraulic telescopic rod 504 is connected to the top of the sliding seat 503. The output end of the second hydraulic telescopic rod 504 is connected to a fixed seat 505. A polishing motor 506 is fixedly connected to one side of the fixed seat 505. The output end of the polishing motor 506 is connected to a polishing shaft 507 via a belt drive system. Next, the polishing shaft 507 is connected to the fixed seat 505 through the bearing. One end of the polishing shaft 507 is connected to the outer wall polishing wheel 508, and one end of the threaded rod 501 passes through the fixed block 502 and is connected to the servo motor 509. By starting the servo motor 509, the threaded rod 501 is controlled to rotate. Combined with the action of the second hydraulic telescopic rod 504, the position of the outer wall polishing wheel 508 can be accurately positioned to meet different height and polishing requirements. Furthermore, during the polishing process, the outer wall polishing wheel 508 moves to polish different positions of the thermos cup.

[0035] Example 2

[0036] Based on Example 1, such as Figures 2-6As shown, a sliding groove 401 is located at the top of a placement groove 8, which is fixed to a polishing table 1. A third hydraulic telescopic rod 9 is fixed inside the placement groove 8. The output end of the third hydraulic telescopic rod 9 is connected to a moving block 10. A third hinge rod 11 is hinged to both sides of the moving block 10. The third hinge rod 11 is connected to a moving sleeve 12. A limiting shaft 13 is connected through the moving sleeve 12. The limiting shaft 13 is connected to an adsorption groove 17 through a fixing plate. The top of the moving sleeve 12 is connected to a limiting seat 15 through a connecting plate 14. A limiting roller 16 is rotatably connected inside the limiting seat 15. By activating the third hydraulic telescopic rod 9, the third hydraulic telescopic rod 9 is extended, causing the third hinge rod 11 to rotate. This allows the moving sleeve to move on the limiting shaft 13, thereby causing the limiting roller 16 to contact the thermos cup. This limits the thermos cup and prevents it from shifting during rotation.

[0037] like Figures 2-6 As shown, an adsorption tank 17 is provided on one side of the placement tank 8. The top of the adsorption tank 17 is provided with an adsorption hole 18. A filter screen 19 is slidably connected inside the adsorption tank 17. The bottom of the adsorption tank 17 is connected to an exhaust fan 20 through an exhaust pipe. One end of the exhaust fan 20 is connected to an exhaust pipe 21. The exhaust pipe 21 is connected through the placement tank 8 and the support frame 2. During the polishing process, the exhaust fan 20 runs continuously, sucking the metal dust generated during polishing into the adsorption tank 17 through the adsorption hole 18. After being filtered by the filter screen 19, it is discharged into the external environment, effectively improving the air quality in the workshop and protecting the health of the operators.

[0038] Working principle: First, the operator places the stainless steel thermos cup to be polished in the designated position in front of the clamping mechanism 3. After the control system 22 detects the workpiece's arrival signal through the sensor, it starts the clamping program: the second drive motor 304 is powered on and the power is transmitted to the reducer 303 through the belt drive system 7. The output end of the reducer 303 drives the fixed shaft to rotate, thereby driving the chuck 302 to open and automatically clamp the bottom of the thermos cup. This clamping structure can be adaptively adjusted according to different specifications of thermos cups to ensure stable clamping without damaging the workpiece surface. Then, the inner wall polishing mechanism 4 starts to operate. The first hydraulic telescopic rod 414 pushes the sliding frame 412 forward along the sliding groove 413, so that the mounting seat 410 approaches the inner wall area of ​​the thermos cup. Subsequently, the rotary motor 411 starts, driving the screw 401 to rotate, which drives the threaded sleeve 402 connected to it to move axially. The threaded sleeve 402 drives the first hinge rod 403 to move via the hinge seat, which in turn pushes the connecting block 408 and the moving plate 404 to expand outward, so that the inner wall polishing wheel 409 fits against the inner wall of the thermos. The limiting rod 415 cooperates with the limiting groove 416 to ensure that the threaded sleeve 402 only moves in a straight line, preventing deviation or jamming. At this time, the first drive motor 604 in the drive mechanism 6 starts, drives the drive shaft 602 to rotate through the belt transmission system 7, and further drives the mounting base 410 to rotate as a whole, so that the inner wall polishing wheel 409 rotates at high speed and continuously polishes the inner wall of the thermos. At the same time, in terms of outer wall polishing, the second hydraulic telescopic rod 504 extends, so that the outer wall polishing component can be adjusted to a suitable position according to the height of the thermos. At the same time, the servo motor 509 drives the threaded rod 501 to rotate, and the sliding seat 503 moves left and right along the threaded rod 501, which drives the fixed seat 505 to move laterally, so that the outer wall polishing wheel 508 is close to the outer wall surface of the thermos. The polishing motor 506 starts, driving the polishing shaft 507 to rotate via the belt drive system 7, which in turn drives the outer wall polishing wheel 508 to rotate at high speed. Then, by restarting the servo motor 509, the outer wall polishing wheel 508 can be moved to complete the polishing process of the outer wall. To improve the stability and safety of the equipment operation, the auxiliary support system starts simultaneously. The third hydraulic telescopic rod 9 extends, driving the moving block 10 to move. The third hinge rod 11 rotates accordingly, driving the moving sleeve 12 to slide along the limiting shaft 13, and finally pushing the limiting seat 15 to move left and right, so that the limiting roller 16 inside contacts the edge of the thermos cup side wall, which plays an auxiliary support and limiting role, effectively preventing the thermos cup from shifting or shaking during high-speed rotation. Throughout the polishing process, the dust removal system runs continuously. The exhaust fan 20 starts, generating negative pressure through the adsorption hole 18 at the top of the adsorption tank 17, sucking the metal dust generated during the polishing process into the adsorption tank 17. After being filtered by filter screen 19, the clean air is discharged to the external environment or workshop circulation system through air outlet duct 21, avoiding dust diffusion and pollution of the work space, and ensuring the health of operators and the safety of equipment operation.Once polishing is complete, the control system 22 issues a reset command, and each actuator stops operating sequentially. The chuck 302 is released, allowing the operator to remove the polished thermos cup and prepare for the clamping and processing of the next workpiece. If any abnormality occurs during operation (such as overload, material interruption, or excessive temperature), the control system 22 will immediately trigger an alarm mechanism and automatically shut down the machine to prevent equipment damage or safety accidents.
