Description

Technical Field

[0001] The utility model belongs to the technical field of thermos cup processing equipment, and particularly refers to a thermos cup cup mouth grinding machine for improving the utilization rate of abrasive belts. Background Technique

[0002] Currently, the thermos cups on the market usually weld the inner liner and the outer liner to form a complete thermos cup. Since the welding position between the inner liner and the outer liner is often rough and burr - bearing, a cup mouth grinding machine is required to further grind the welding position. Basically, the cup mouth grinding machines on the market at present wind the abrasive belt around the grinding head to grind the cup mouth of the outer liner. However, after the abrasive belt is used for a long time, the grinding surface of the abrasive belt will be worn, which will affect the subsequent grinding. Subsequently, the manufacturer has set a turntable assembly for controlling the movement of the abrasive belt. The turntable assembly includes a turntable and a hydraulic mechanism for driving the turntable to rotate. When the grinding surface of the abrasive belt is worn, the hydraulic mechanism can drive the turntable to rotate, so that the worn part of the grinding surface on the abrasive belt can be wound around the turntable. At this time, the turntable will drive the abrasive belt to move, so that the grinding surface of the abrasive belt on the grinding head is new again. However, due to the stability of the control accuracy of the hydraulic mechanism being affected by many factors, it cannot accurately control the rotation angle of the turntable, resulting in different moving distances of the abrasive belt each time. This will cause some grinding surfaces on the abrasive belt not to be utilized, thus greatly reducing the utilization rate of the abrasive belt and causing waste. Summary of the Invention

[0015] The prominent and beneficial technical effects of the present utility model compared with the prior art are:

[0016] A polishing machine for the cup mouth of a heat-insulating cup to improve the utilization rate of abrasive belts, comprising a machine body, a mounting frame arranged on the machine body, a turntable assembly mounted on the mounting frame, and a polishing assembly. An installation sleeve and a driving assembly for driving the installation sleeve to rotate are provided on the machine body. The polishing assembly is arranged directly above the installation sleeve. The turntable assembly includes an abrasive belt storage turntable and an abrasive belt placement turntable. An abrasive belt can be installed on the abrasive belt placement turntable. One end of the abrasive belt extends from the abrasive belt placement turntable, winds around the surface of the polishing assembly, and is wound onto the abrasive belt storage turntable. The abrasive belt on the polishing assembly is in contact with the welded part of the heat-insulating cup. A servo output motor is further provided on the mounting frame. An output shaft is provided on the servo output motor. A driving shaft and a driven shaft are provided on the mounting frame. The abrasive belt storage turntable is sleeved on the driving shaft, and the abrasive belt placement turntable is sleeved on the driven shaft. The output shaft is directly or indirectly connected to the driving shaft, and the output shaft can drive the driving shaft to rotate. A displacement detection device is further provided on the mounting frame. The displacement detection device is arranged on one side of the abrasive belt. A mold for placing the heat-insulating cup is provided on the installation sleeve. The polishing assembly is arranged directly above the mold. After the driving assembly works, it drives the installation sleeve to rotate. At this time, the mold and the heat-insulating cup in the mold rotate for polishing. After the heat-insulating cup is polished, the servo output motor drives the output shaft to rotate to drive the abrasive belt storage turntable to rotate. After the abrasive belt storage turntable rotates to pull the abrasive belt to move, when the displacement detection device detects that the moving distance of the abrasive belt reaches the set value, at this time, the displacement detection device transmits the data signal of the moving distance of the abrasive belt to the servo output motor, thereby controlling the servo output motor to stop working, so as to control the distance that the abrasive belt storage turntable pulls the abrasive belt to move each time to be the same, and make the abrasive belt on the surface of the polishing assembly become a new abrasive belt;When in use, the user places the thermos cup completed by welding the inner liner and the outer liner into the mold on the mounting sleeve, and the user can replace different molds according to the size of the thermos cup, so that thermos cups of different sizes can be smoothly placed into the mold for grinding, which is more practical. The grinding assembly includes a grinding head and a cam pendulum. The grinding head is arranged directly above the mold. At this time, the welded joint of the thermos cup is directly below the grinding head. Since there is an output shaft on the servo output motor on the mounting frame, when the servo output motor starts to work, it will drive the output shaft to rotate. Since the output shaft is directly or indirectly connected to the driving shaft, and one end of the sand belt on the sand belt placement turntable extends from the sand belt placement turntable, winds around the surface of the grinding head and winds onto the sand belt storage turntable. The sand belt on the surface of the grinding head will contact the welded joint of the thermos cup. When the driving assembly starts to work, it will drive the mounting sleeve to rotate together. After the mounting sleeve rotates, it will drive the mold on the mounting sleeve to rotate. At this time, the thermos cup in the mold will rotate synchronously with the mold and contact the sand belt on the surface of the grinding head, so as to grind the welded joint. Compared with the cup mouth grinding machine on the market, which drives the turntable to rotate through a hydraulic mechanism to control the moving distance of the sand belt, so that the grinding surface of the sand belt on the grinding head is replaced with a new one. However, due to the stability of the control accuracy of the hydraulic mechanism being affected by many factors, it cannot accurately control the rotation angle of the turntable, resulting in different moving distances of the sand belt each time. This will cause some grinding surfaces on the sand belt not to be utilized, thus greatly reducing the utilization rate of the sand belt and causing waste. The motor of the present utility model is a servo motor. When the grinding surface of the sand belt on the surface of the grinding head is worn to a certain extent, at this time, the servo output motor will work to drive the output shaft to rotate. The rotation of the output shaft will drive the driving shaft to rotate, and the rotation of the driving shaft will drive the sand belt storage turntable on the driving shaft to rotate, so that the sand belt storage turntable on the driving shaft can pull the sand belt to move and wind the sand belt on the sand belt storage disk. When the sand belt storage turntable rotates with the increasing number of wound sand belts, the overall diameter of the sand belt storage turntable will become longer. At this time, when the sand belt storage turntable continues to rotate to pull the sand belt to move, the displacement detection device will detect the moving distance of the sand belt. When the moving distance of the sand belt reaches the initially set value, the displacement detection device will transmit the data signal to the servo output motor, so as to control the output shaft on the servo output motor to stop rotating and make the servo motor stop working immediately. At this time, the sand belt storage turntable on the output shaft will also stop pulling the sand belt, so as to ensure that the moving distance of the sand belt is the same each time, make the sand belt on the surface of the grinding head become a new sand belt, and there will be no unused sand belt grinding surface between the adjacent used sand belt grinding surfaces, so that the grinding surface on the sand belt can be fully utilized and the waste of the sand belt will not be caused.; BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The present utility model will be further described below in conjunction with specific embodiments:

The abrasive belt storage turntable 5 is sleeved on the driving shaft 11. The abrasive belt placement turntable 6 is sleeved on the driven shaft 12. The output shaft 10 is directly or indirectly connected to the driving shaft 11. The output shaft 10 can drive the driving shaft 11 to rotate. A displacement detection device 13 is further provided on the mounting frame 2. The displacement detection device 13 is arranged on one side of the abrasive belt 7. A mold for placing the heat-insulating cup is provided on the installation sleeve 3. The polishing assembly 4 is arranged directly above the mold. After the driving assembly works, it drives the installation sleeve 3 to rotate. At this time, the mold and the heat-insulating cup in the mold rotate for polishing. After the heat-insulating cup is polished, the servo output motor 8 drives the output shaft 10 to rotate to drive the abrasive belt storage turntable 5 to rotate. After the abrasive belt storage turntable 5 rotates to pull the abrasive belt 7 to move, when the displacement detection device 13 detects that the moving distance of the abrasive belt 7 reaches the set value, at this time, the displacement detection device 13 transmits the data signal of the moving distance of the abrasive belt 7 to the servo output motor 8, thereby controlling the servo output motor 8 to stop working, so as to control the distance that the abrasive belt storage turntable 5 pulls the abrasive belt 7 to move each time to be the same, and make the abrasive belt 7 on the surface of the polishing assembly 4 become a new abrasive belt 7;When in use, the user places the thermos cup completed by welding the inner liner and the outer liner into the mold on the mounting sleeve 3, and the user can replace different molds according to the size of the thermos cup, so that thermos cups of different sizes can be smoothly placed into the mold for grinding, with stronger practicability. Moreover, the grinding assembly 4 includes a grinding head 37 and a cam ornament 38. The grinding head 37 is arranged directly above the mold. At this time, the welded joint of the thermos cup is located directly below the grinding head 37. Since there is an output shaft 10 on the servo output motor 8 on the mounting frame 2, when the servo output motor 8 starts to work, it will drive the output shaft 10 to rotate. Since the output shaft 10 is directly or indirectly connected to the driving shaft 11, and one end of the abrasive belt 7 on the abrasive belt placement turntable 6 extends from the abrasive belt placement turntable 6, winds around the surface of the grinding head 37 and winds onto the abrasive belt storage turntable 5. The abrasive belt 7 on the surface of the grinding head 37 will contact the welded joint of the thermos cup. When the driving assembly starts to work, it will drive the mounting sleeve 3 to rotate together. After the mounting sleeve 3 rotates, it will drive the mold on the mounting sleeve 3 to rotate. At this time, the thermos cup in the mold will rotate synchronously with the mold and contact the abrasive belt 7 on the surface of the grinding head 37, so as to grind the welded joint. Compared with the cup mouth grinding machine on the market, which drives the turntable to rotate through a hydraulic mechanism to control the moving distance of the abrasive belt 7, so that the grinding surface of the abrasive belt 7 on the grinding head 37 is replaced with a new one. However, due to the stability of the control accuracy of the hydraulic mechanism being affected by many factors, it cannot accurately control the rotation angle of the turntable, resulting in different moving distances of the abrasive belt 7 each time. This will cause some grinding surfaces on the abrasive belt 7 not to be utilized, thus greatly reducing the utilization rate of the abrasive belt 7 and causing waste. The motor of the present utility model is a servo motor. When the grinding surface of the abrasive belt 7 on the surface of the grinding head 37 is worn to a certain extent, at this time, the servo output motor 8 will work to drive the output shaft 10 to rotate. The rotation of the output shaft 10 will drive the driving shaft 11 to rotate. The rotation of the driving shaft 11 will drive the abrasive belt storage turntable 5 on the driving shaft 11 to rotate, so that the abrasive belt storage turntable 5 on the driving shaft 11 can pull the abrasive belt 7 to move and wind the abrasive belt 7 onto the abrasive belt storage turntable 5. When the overall diameter of the abrasive belt storage turntable 5 becomes longer as the number of the wound abrasive belts 7 increases, at this time, when the abrasive belt storage turntable 5 continues to rotate to pull the abrasive belt 7 to move, the displacement detection device 13 will detect the moving distance of the abrasive belt 7. When the moving distance of the abrasive belt reaches the initially set value, the displacement detection device 13 will transmit the data signal to the servo output motor 8, so as to control the output shaft 10 on the servo output motor 8 to stop rotating and make the servo motor stop working immediately. At this time, the abrasive belt storage turntable 5 on the output shaft 10 will also stop pulling the abrasive belt, so as to ensure that the moving distance of the abrasive belt 7 is the same each time, make the abrasive belt 7 on the surface of the grinding head 37 become a new abrasive belt 7, and there will be no unused abrasive belt grinding surface between the adjacent used abrasive belt grinding surfaces, so that the grinding surfaces on the abrasive belt 7 can be fully utilized and the waste of the abrasive belt 7 will not be caused.;

[0057] Preferably, an installation seat 14 is provided on the mounting bracket 2. The displacement detection device 13 includes an encoder motor 15 and a rotating disk 16. The encoder motor 15 is installed on the installation seat 14. A motor shaft 17 is provided on the encoder motor 15. The rotating disk 16 is sleeved on the motor shaft 17. The rotating disk 16 is in contact with the abrasive belt 7. The movement of the abrasive belt 7 can drive the rotating disk 16 to rotate. The setting of the installation seat 14 enables the encoder motor 15 to be smoothly installed on the mounting bracket 2. Moreover, the encoder motor 15 is a common motor on the market, which is a device that can encode signals or data and convert them into signal forms available for communication, transmission, and storage. Since the rotating disk 16 is sleeved on the motor shaft 17 of the encoder motor 15 and the rotating disk 16 is in contact with the abrasive belt 7, when the abrasive belt 7 moves upward, it can drive the rotating disk 16 to rotate together. After the rotating disk 16 rotates, it will drive the motor shaft 17 to rotate. At this time, the encoder can detect the moving distance of the abrasive belt 7 through the rotation angle of the rotating disk 16. When the encoder detects that the moving distance of the abrasive belt reaches the initially set value, it will transmit a signal to the servo output motor 8, so that the servo output motor 8 controls the output shaft 10 to stop rotating. At this time, the abrasive belt storage turntable 5 cannot pull the abrasive belt 7 to move, thus ensuring that the moving distance of the abrasive belt 7 is the same each time.

[0058] Preferably, a sliding seat 18 is arranged inside the fuselage 1. The sliding seat 18 is arranged behind the mounting frame 2. A longitudinal sliding guide rail 19 is provided on the sliding seat 18. A longitudinal sliding plate 21 is provided on the longitudinal sliding guide rail 19. A longitudinal sliding block 20 is provided on the rear side of the longitudinal sliding plate 21. The longitudinal sliding block 20 is slidably connected to the longitudinal sliding guide rail 19. A longitudinal adjusting block 22 is further provided on the rear side of the longitudinal sliding plate 21. A longitudinal servo motor 23 is provided at the top of the sliding seat 18. A longitudinal coupling 24 is connected to the longitudinal servo motor 23. A longitudinal lead screw 25 is connected to the longitudinal coupling 24. A longitudinal threaded hole 26 is formed in the longitudinal adjusting block 22. The longitudinal lead screw 25 is arranged in the longitudinal threaded hole 26 and is threadedly connected to the longitudinal adjusting block 22. A connecting plate 27 is provided on the front side of the longitudinal sliding plate 21. One end of the connecting plate 27 is connected to the mounting frame 2. Since the longitudinal sliding block 20 on the longitudinal sliding plate 21 is slidably connected to the longitudinal sliding guide rail 19 on the sliding seat 18, the longitudinal sliding plate 21 can move up and down relative to the sliding seat 18. And the connecting plate 27 on the front side of the longitudinal sliding plate 21 is connected to the mounting frame 2. The longitudinal servo motor 23 is connected to the longitudinal lead screw 25 through the longitudinal coupling 24. And the longitudinal lead screw 25 passes through the longitudinal threaded hole 26 of the longitudinal adjusting block 22 and is threadedly connected to the longitudinal adjusting block 22. The setting of the longitudinal coupling 24 enables the longitudinal servo motor 23 to drive the longitudinal lead screw 25 to rotate smoothly after working. When the longitudinal servo motor 23 works to drive the longitudinal lead screw 25 to rotate, at this time, the longitudinal adjusting block 22 on the longitudinal lead screw 25 will move along the longitudinal lead screw 25. The longitudinal adjusting block 22 will drive the longitudinal sliding plate 21 to move along the longitudinal sliding guide rail 19 through the longitudinal sliding block 20. Thus, the connecting plate 27 on the longitudinal sliding plate 21 will move together with the longitudinal sliding plate 21, and finally drive the mounting frame 2 to move. Since the turntable assembly and the grinding assembly 4 are installed on the mounting frame 2, when the mounting frame 2 moves upward, the grinding assembly 4 will also move upward. Thus, the user can take out the ground thermos cup from the mounting sleeve 3. After taking out the ground thermos cup, the user can put the thermos cup to be ground into the mounting sleeve 3. At this time, the longitudinal servo motor 23 drives the longitudinal lead screw 25 to reverse, so that the abrasive belt 7 on the surface of the grinding head 37 can contact the cup mouth of the thermos cup again.

[0059] Preferably, a transverse sliding guide rail 28 is provided on the front side of the longitudinal sliding plate 21, a transverse sliding block 29 is provided on the rear side of the connecting plate 27, the transverse sliding block 29 is slidably connected to the transverse sliding guide rail 28, a transverse servo motor 30 is provided on one side of the longitudinal sliding plate 21, a transverse coupling 31 is connected to the transverse servo motor 30, a transverse lead screw 32 is connected to the transverse coupling 31, a transverse adjusting block 33 is further provided on the rear side of the connecting plate 27, a transverse threaded hole 34 is formed in the transverse adjusting block 33, and the transverse lead screw 32 is arranged in the threaded hole and is threadedly connected to the transverse adjusting block 33; the transverse sliding block 29 on the rear side of the connecting plate 27 is slidably connected to the transverse sliding guide rail 28 on the front side of the longitudinal sliding plate 21, so that the connecting plate 27 can move back and forth relative to the longitudinal sliding plate 21. When the position of the abrasive belt 7 on the lower surface of the grinding head 37 deviates from the welding position of the thermos cup, resulting in the abrasive belt 7 being unable to contact the welding position of the thermos cup, at this time, after controlling the transverse servo motor 30 to start working, the transverse servo motor 30 will drive the transverse lead screw 32 to rotate through the transverse coupling 31. Since the transverse lead screw 32 is arranged in the threaded hole of the transverse adjusting block 33 and is threadedly connected to the transverse adjusting block 33, when the transverse lead screw 32 rotates, it will drive the transverse adjusting block 33 to move back and forth on the transverse lead screw 32. At this time, the connecting plate 27 can move together with the transverse adjusting block 33, and finally the connecting plate 27 drives the mounting frame 2 to move, so that the grinding head 37 on the mounting frame 2 can be located directly above the welding position of the thermos cup, and the abrasive belt 7 on the grinding head 37 can contact the welding position. At this time, control the driving assembly to work to drive the thermos cup to rotate at a high speed, so that the welding position of the thermos cup can be smoothly polished.

[0060] Preferably, an installation part 35 is provided at the bottom of the mounting bracket 2. The front end of the connecting plate 27 is fixedly connected to the installation part 35. Shelf plates 36 are symmetrically provided at the bottom of the installation part 35. The grinding assembly 4 includes a grinding head 37 and a cam pendulum 38. The grinding head 37 is fixedly installed at the bottom end of the cam pendulum 38.

A drive threaded hole 47 is formed in the drive block 46. The drive lead screw 45 is arranged in the drive threaded hole 47 and is threadedly connected to the drive block 46. Since the servo drive motor 43 can drive the drive lead screw 45 to rotate through the drive coupling 44, and the drive lead screw 45 is threadedly connected to the drive block 46 in the drive threaded hole 47 formed in the drive block 46, and the drive block 46 is fixedly connected to the rack 40. When the drive assembly drives the height of the thermos cup to rotate, and the user wants a better grinding effect on the welded part of the thermos cup. Since the rack 40 is slidably connected to the guide block 39 between the symmetrically arranged shelf plates 36, it can prevent the rack 40 from disengaging from the shelf plates 36 and disengaging from the gear part 41 at the top end of the cam pendulum 38. The user can set the servo drive motor 43 to rotate forward first and then reverse through the program. After the servo drive motor 43 starts to work, the servo drive motor 43 can smoothly drive the drive lead screw 45 to rotate forward through the coupling. When the drive lead screw 45 rotates forward, it will cause the drive block 46 to move forward on the drive lead screw 45. The drive block 46 drives the rack 40 to move forward together along the guide block 39 at the bottom of the installation part 35. Since the rack 40 meshes with the gear part 41 at the top end of the lower cam pendulum 38, and the cam pendulum 38 is rotatably arranged between the symmetrically arranged shelf plates 36. When the rack 40 moves forward, it will drive the cam pendulum 38 to swing forward. When the cam pendulum 38 rotates forward to the moving angle, the servo drive motor 43 will drive the drive lead screw 45 to rotate in the reverse direction through the drive coupling 44, and the cam pendulum 38 will swing backward. Repeating this back and forth, finally, the grinding head 37 at the bottom end of the cam pendulum 38 will swing reciprocally, so that the abrasive belt 7 on the lower surface of the grinding head 37 can better grind the welded part of the thermos cup.

[0061] Preferably, the mounting portion 35 includes symmetrically arranged fixing plates 48. An extension plate 49 is formed by extending the front end of the connecting plate 27.

And the extension plate 49 is disposed between the symmetric fixing plates 48, which can limit the random left - right movement of the extension plate 49. Moreover, this connection method makes the connection between the extension plate 49 and the fixing plates 48 more stable and firm. When the extension plate 49 moves forward - backward or up - down, it can smoothly drive the mounting portion 35 and the mounting frame 2 to move together.

[0062] Preferably, a limiting plate 52 is provided at the end of the longitudinal sliding plate 21 facing the mounting portion 35.

An abutting portion 54 is provided on the servo - drive motor 43. The abutting portion 54 can abut against the outer side surface of the limiting plate 52. The channel 53 in the limiting plate 52 enables the extension plate 49 at the front end of the connecting plate 27 to smoothly pass through and be fixedly connected to the mounting portion 35. And the inner side surface of the limiting plate 52 is in contact with one end of the transverse sliding guide rail 28, which can prevent the situation that the connecting plate 27 and the transverse slider 29 move forward along the transverse sliding guide rail 28 and break away from the transverse sliding guide rail 28. And when the connecting plate 27 and the transverse slider 29 move backward a certain distance along the transverse sliding guide rail 28, at this time, the abutting portion 54 on the servo - drive motor 43 will abut against the outer side surface of the limiting plate 52, thereby restricting the connecting plate 27 and the transverse slider 29 from continuing to move backward and preventing the situation that the connecting plate 27 and the transverse slider 29 break away from the transverse sliding guide rail 28, without affecting the normal use of the grinding machine.

[0063] Preferably, fixing seats 55 are provided on the shelf plates 36, and friction assemblies 56 are provided on the fixing seats 55.

Since the first friction wheel 59 and the second friction wheel 60 are rotatably sleeved on the first mounting rod 57 and the second mounting rod 58 respectively, and the abrasive belt 7 first extends from the abrasive belt storage turntable 5, passes through the middle of the left first friction wheel 59 and the second friction wheel 60, then winds around the surface of the grinding head 37, and then passes through the middle of the right first friction wheel 59 and the second friction wheel 60 and winds back onto the abrasive belt storage turntable 5. Moreover, the first friction wheel 59 and the second friction wheel 60 are both knurled, so that the friction force between the first friction wheel 59 and the second friction wheel 60 and the abrasive belt 7 can be increased, the moving speed of the abrasive belt 7 can be restricted, thereby ensuring that the abrasive belt 7 is in close contact with the lower surface of the grinding head 37 and will not affect the normal grinding of the thermos cup.

The setting of the connecting piece 67 enables the main shaft motor 64 to smoothly drive the main shaft 63 to rotate after working. Since the connecting portion 68 at the top end of the main shaft 63 is fixedly connected to the bottom of the mounting sleeve 3, when the main shaft 63 rotates, the mounting sleeve 3 will also rotate, and finally the thermos cup rotates together with the mounting sleeve 3, so that the welded joint of the thermos cup in the mounting sleeve 3 can be polished smoothly. Moreover, compared with ordinary motors on the market, the main shaft motor 64 has characteristics such as high speed, high precision, and high stability. And because it adopts advanced technologies such as brushless motor technology and variable frequency control technology, it can minimize energy loss and save energy costs.
