Description

Technical Field

[0001] This invention belongs to the field of faucet processing technology, specifically a continuous polishing and grinding device for faucets. Background Technology

[0002] A faucet is a device installed at the end of a water supply pipe to control the flow of water, regulate the flow rate and temperature, and guide the water flow in a specific direction. Its core function is to connect the water supply system with the end-use scenarios, such as hand washing, vegetable washing, and showering, to achieve precise control of water use as needed. It is an indispensable terminal component in modern building water supply and drainage systems.

[0003] A patent application with publication number CN106392834A discloses a faucet polishing device. The present invention divides the six spatial degrees of freedom of the robot itself in the conventional technology into x and y translational degrees of freedom of the working platform, z translational degree of freedom of the polishing component, and three rotational degrees of freedom of the clamping end, thereby reducing the number of robot joints and shortening the suspended length of the robotic arm. Therefore, it can increase the rigidity and stability of the polishing device as a whole and greatly improve the processing accuracy.

[0004] Currently, in existing technologies, polishing faucet nozzles involves a large number of nozzles being produced, requiring manual disassembly and clamping before and after the polishing process. This is typically a single-station, serial processing operation. This method may result in a gap between disassembly and clamping of the polished workpiece, consuming both production time and manpower.

[0005] Therefore, the present invention provides a continuous polishing and grinding device for faucets. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a continuous polishing and grinding device for a faucet, including a housing, a conveyor belt on one side of the housing, an inclined slide fixedly installed on one side of the housing, the inclined slide being positioned above the conveyor belt, a rotary box fixedly installed inside the housing, four sets of transfer components on the outside of the rotary box, the transfer components being used for clamping and rotating the nozzle, two sandblasting boxes inside the housing, each sandblasting box containing a sandblasting device, the sandblasting device being used for sandblasting, polishing and grinding the nozzle, and an unloading component inside the housing, the unloading component including a shifting rod, the unloading component being used to automatically remove the nozzle from the transfer component and into the conveyor belt after the sandblasting device finishes polishing and grinding the nozzle;

[0008] When polishing is required on the faucet nozzle, the nozzle is inserted into the mounting assembly on one side of the interchange box. The mounting assembly then automatically clamps and secures the nozzle. Once secured, the mounting assembly rotates the nozzle through two sandblasting chambers within the housing. The sandblasting devices within these chambers then perform sandblasting, thus polishing the nozzle. After polishing, the mounting assembly continues to rotate the nozzle. When the nozzle moves above the unloading assembly, the unloading assembly automatically pushes the nozzle from the mounting assembly using a shifting rod, thus removing the nozzle from the mounting assembly. The component slides out and finally falls onto the conveyor belt via the inclined slide. Compared to manual disassembly and clamping, the internal structure of the machine housing can be divided into four workstations by setting up four sets of transfer components: one clamping workstation, two grinding workstations, and one unloading workstation. When one of the transfer components drives the nozzle to rotate and grind, the nozzle can be placed on the other three transfer components through its rotation. With the help of the unloading components to unload and remove the nozzle, continuous polishing and grinding of the nozzle can be achieved. This can save some time for manual downtime for unloading and installing nozzles, and is more conducive to polishing and grinding the nozzle during processing and production, thus improving processing efficiency.

[0009] Preferably, the transfer assembly includes a positioning plate. One side of the positioning plate can slide against the outer wall of the transfer box, and a shaft is fixedly installed on the other side of the positioning plate. Shaft discs are symmetrically fixedly installed inside the shaft. Multiple support blocks are slidably connected between the inner walls of the two shaft discs. Multiple return springs are provided between one side of each support block and the inner wall of the shaft. The outer walls of each support block can contact the inner wall of the nozzle. When the nozzle needs to be fixed, it is inserted into the outside of the shaft. When one end of the nozzle contacts the positioning plate, the multiple support blocks inside the shaft are pushed to... When the support blocks move within the shaft, they pull the return springs to move outwards along the opening of the shaft disc. Multiple support blocks expand outwards as they move. When the outer walls of all support blocks contact the inner wall of the nozzle, the nozzle is fixed to one side of the positioning plate, thus securing it in place. Simultaneously, by pulling the return springs outwards within the shaft disc, the support blocks can fix various diameter faucet nozzles, increasing versatility during operation.

[0010] Preferably, a fixed-tube motor is fixedly installed on the inner wall of the shaft, and round shafts are fixedly installed at both output ends of the fixed-tube motor. Push rods are symmetrically fixedly installed on the outer walls of multiple support blocks, and one end of each push rod is cut into an inclined surface. Multiple rotating rods are fixedly installed on the outer walls of the two round shafts, and the outer walls of the rotating rods can slide and connect with the outer walls of the push rods respectively. When it is necessary to move the support block, the fixed-tube motor is driven to rotate the round shaft, which in turn drives the multiple rotating rods to rotate. When the rotating rods rotate, they will squeeze the multiple push rods, and the multiple push rods will be pushed by the pressure to move the support block outward by pulling the return spring, thereby causing the support block to expand outward. When the nozzle is fixed, the fixed-tube motor is reversed, the rotating rods will reset, the push rods will lose thrust, and the return spring will drive the support block to retract into the shaft for reset, providing a clamping base for the next clamping and providing pushing power for the movement of the support block.

[0011] Preferably, a rotation motor is fixedly installed on the inner wall of the rotation box, and a rotating shaft is fixedly installed on one output end of the rotation motor. The top of the rotating shaft is rotatably connected to the inner wall of the rotation box, and four connecting shafts are fixedly installed on the outer wall of the rotating shaft. Four sets of rotation components are respectively set on one side of the four connecting shafts. When the nozzle is fixed by the external support of multiple support blocks, the rotating shaft is driven to rotate by driving the rotation motor. The rotating shaft will then drive the nozzle to rotate inside the machine housing through the connecting shafts. Thus, the rotation motor drives the nozzle from the clamping station through the grinding area and finally into the unloading station, which plays the role of driving the nozzle to rotate.

[0012] Preferably, two telescopic cylinders are fixedly installed on the inner wall of the housing. The output ends of the two telescopic cylinders are fixedly connected to the outer walls of the two sandblasting boxes respectively. Both sandblasting boxes can be placed outside the spray pipe. When the rotary motor drives the spray pipe to move below the sandblasting box, the telescopic cylinder drives the sandblasting box to move downward. The telescopic cylinder will then drive the sandblasting device inside it to move towards the spray pipe. When the sandblasting device moves above the spray pipe, the sandblasting box completely covers the spray pipe. Then the sandblasting device will perform sandblasting and polishing operations on one side of the spray pipe. With the setting of two sandblasting boxes, when the polishing of one side of the spray pipe is finished, the telescopic cylinder is controlled to drive the sandblasting box to reset. Then the rotary motor drives the spray pipe to move below the other sandblasting box. The other telescopic cylinder will then drive the sandblasting device in the other sandblasting box to move down to sandblast and polish the other side of the spray pipe, thereby realizing the comprehensive sandblasting and polishing operation of the spray pipe, which serves the function of sandblasting and polishing the faucet spray pipe.

[0013] Preferably, a geared disc is fixedly installed on the inner wall of the indexing box, and a ring shaft is fixedly installed on the outer wall of the positioning plate. The outer wall of the ring shaft is rotatably connected to the inner wall of the indexing box, and the inner wall of the ring shaft is rotatably connected to the inner wall of the connecting shaft. A geared ring is fixedly installed on the outer wall of the ring shaft, and the teeth on the geared ring can mesh with the teeth on the geared disc. When the indexing motor drives the rotating shaft to rotate, the rotating shaft will drive the positioning plate to rotate through the connecting shaft. When the positioning plate rotates, the geared ring on one side of the positioning plate will automatically rotate along the direction of the teeth on the geared disc. Thus, when the indexing motor drives the nozzle to rotate, the geared ring drives the nozzle to rotate through the positioning plate. This facilitates the automatic flipping of the nozzle when it moves to the bottom of the two sandblasting boxes, allowing the two sandblasting devices to perform sandblasting operations on both sides of the nozzle, thereby achieving the function of automatically flipping the nozzle.

[0014] Preferably, the unloading assembly also includes two torque rods and two displacement rods. The two displacement rods can be placed on one side of the nozzle. Each of the two displacement rods is equipped with a pusher block at its top. Two sets of limiting plates are symmetrically fixedly installed on the inner wall of the housing. The outer walls of the two displacement rods are slidably connected to the inner walls of the two sets of limiting plates. The outer wall of the pusher block can contact the outer wall of the nozzle. When the indexing motor drives the nozzle to rotate above the displacement rod, the fixed pipe motor is reversed by controlling it, and the support block will reset to unload the nozzle. Then, by pushing the torque rod to move, the torque rod will drive the displacement rod to slide between the two limiting plates. The displacement rod will then drive the pusher block to push the nozzle through the sliding, thereby pushing the nozzle through the inclined slide and into the conveyor belt, which plays the role of pushing the nozzle for unloading.

[0015] Preferably, two slot frames are fixedly installed on the inner wall of the housing, and guide shafts are fixedly installed on the inner wall of the slot frames. The outer walls of the two guide shafts are slidably connected to the inner walls of the two shift rods, and the bottoms of the two shift rods are slidably connected to the tops of the two slot frames. A return spring is provided between the inner walls of the two slot frames and the outer walls of the two shift rods. The two return springs are respectively placed outside the two guide shafts. When the push rod drives the shift rod to move, the shift rod will move at the top of the slot frame, and the shift rod will pull the return spring to move on the guide shaft. When the pusher pushes the nozzle out of the shaft, the push on the pusher stops, and the return spring will elastically pull the shift rod to reset, providing a pushing basis for the next push of the nozzle, thus playing the role of resetting the shift rod.

[0016] Preferably, the bottoms of the two push tube blocks are hinged to the tops of the two shift rods respectively. A pressure spring is provided between one side of each push tube block and the outer wall of each shift rod. One side of the top of each push tube block is opened as an inclined surface. When the return spring pulls the shift rod to reset, the shift rod will drive the push tube block to reset. Since the rotary motor will drive the nozzle to rotate when the push tube block resets, when the push tube block resets and encounters the nozzle, when one side of the push tube block contacts the outer wall of the nozzle, the nozzle will be limited and thus squeeze the pressure spring at the top of the shift rod to rotate. The push tube block will then slide along the outer wall of the nozzle and eventually move to the other side of the nozzle, avoiding interference between the two during reset and playing the role of avoiding the nozzle during reset.

[0017] Preferably, four magnetically shielding arc plates are fixedly installed at the other output end of the indexing motor. The bottom of each of the four magnetically shielding arc plates is rotatably connected to the inner wall of the housing. An electromagnet is fixedly installed on the inner wall of the indexing box. The four magnetically shielding arc plates are respectively placed outside the electromagnet. A slot is fixedly installed between the two rods. A magnetic block is fixedly installed on the inner wall of the slot. The position of the magnetic block corresponds to the position of the electromagnet. The outer wall of the slot is slidably connected to the inner wall of the housing. When the indexing motor drives the nozzle to rotate, the indexing motor will drive the magnetically shielding arc plates to rotate together. The indexing motor will then rotate at the electromagnet. The nozzle rotates externally. When the nozzle rotates above the shift rod, the magnetic shielding plate stops blocking the electromagnet. The electromagnet then uses magnetism to move the magnetic block, which in turn moves the two rods through the slot, thus providing power for the movement of the shift rod. The purpose of this design is that when the nozzle rotates above the shift rod, the electromagnet can directly move the magnetic block through the opening between the two magnetic shielding plates, allowing the shift rod to push the nozzle immediately. This reduces the time required to turn the power source on and off, making the nozzle machining process more convenient.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The continuous polishing and grinding device for a faucet according to the present invention, through the setting of four sets of transfer components, can divide the interior of the machine housing into four work stations, namely one clamping work station, two grinding work stations and one unloading work station. When one of the transfer components drives the nozzle to rotate and grind, the nozzle can be placed on the other three sets of transfer components through its rotation. With the help of the unloading components to unload and remove the nozzle, the continuous polishing and grinding operation of the nozzle can be realized. This can save a certain amount of time for manual downtime to unload and install the nozzle, and is more conducive to the polishing and grinding of the nozzle during processing and production, thereby improving the processing efficiency.

[0020] 2. The continuous polishing and grinding device for faucets according to the present invention involves inserting a spray pipe into the outside of a shaft, and then pushing the support blocks to pull the return spring to move outward from the shaft. When the outer walls of multiple support blocks contact the inner wall of the spray pipe, the multiple support blocks will fix the spray pipe to one side of the positioning plate through external support, thereby fixing the spray pipe. By having multiple support blocks pull the return spring to move outward within the shaft plate for expansion, multiple support blocks can fix spray pipes of various different diameters, increasing the applicability during operation.

[0021] 3. The continuous polishing and grinding device for a faucet described in this invention, when the positioning plate rotates, the toothed ring on one side of the positioning plate will automatically rotate along the tooth direction of the toothed disc. Thus, when the rotary motor drives the nozzle to rotate, the toothed ring drives the nozzle to rotate through the positioning plate. This facilitates the automatic flipping of the nozzle when it moves to the bottom of the two sandblasting boxes, allowing the two sandblasting devices to perform sandblasting operations on both sides of the nozzle, thereby achieving the function of automatically flipping the nozzle.

[0022] 4. The continuous polishing and grinding device for a faucet according to the present invention, when the rotary motor drives the nozzle to rotate above the shifting rod, the fixed pipe motor is reversed by controlling the fixed pipe motor to reset and unload the nozzle. Then, by pushing the torque rod to move, the torque rod will drive the shifting rod to slide between the two limit plates. The shifting rod will then drive the pusher block to push the nozzle through the sliding, thereby pushing the nozzle through the inclined slide table and into the conveyor belt, which plays the role of automatically pushing the nozzle for unloading.

[0023] 5. The continuous polishing and grinding device for a faucet according to the present invention uses a rotary motor to drive a magnetically shielded arc plate to rotate. When the nozzle rotates above the shifting rod, the magnetically shielded arc plate stops blocking the electromagnet, and the electromagnet then pushes the magnetic block to move through magnetism. The magnetic block provides power for the movement of the shifting rod. This allows the electromagnet to directly push the magnetic block through magnetism through the opening between the two magnetically shielded arc plates when the nozzle rotates above the shifting rod, so that the shifting rod can push the nozzle immediately, reducing the time required to turn the power source on and off, and making it more convenient for the processing of the nozzle.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figures 1 to 10As shown in the embodiment of the present invention, a continuous polishing and grinding device for a faucet includes a housing 1, a conveyor belt 2 on one side of the housing 1, an inclined slide 5 fixedly installed on one side of the housing 1, the inclined slide 5 being positioned above the conveyor belt 2, a rotary box 4 fixedly installed inside the housing 1, four sets of transfer components on the outside of the rotary box 4, the transfer components being used for clamping and rotating the spray pipe, two sandblasting boxes 3 inside the housing 1, each of the two sandblasting boxes 3 being equipped with a sandblasting device 302, the sandblasting device 302 being used for sandblasting, polishing and grinding the spray pipe, and an unloading assembly inside the housing 1, the unloading assembly including a shifting rod 6, the unloading assembly being used to automatically remove the spray pipe from the transfer assembly and into the conveyor belt 2 after the sandblasting device 302 finishes polishing and grinding the spray pipe;

[0038] Because the production and processing of faucet nozzles involves a large number of parts, manual disassembly and clamping are usually required before and after the operation, and it is mostly a single-station serial processing operation. This method may result in a window period between disassembly and clamping of the workpiece after polishing, which not only consumes production time but also wastes a certain amount of manpower.

[0039] When polishing is required on the faucet nozzle, the nozzle is inserted into the transfer assembly on one side of the indexing box 4. The transfer assembly then automatically clamps and secures the nozzle. Once secured, the transfer assembly rotates the nozzle through two sandblasting boxes 3 within the housing 1. The sandblasting device 302 within the sandblasting box 3 performs sandblasting, thus polishing the nozzle. After polishing, the transfer assembly continues to rotate the nozzle. When the nozzle moves above the unloading assembly, the unloading assembly automatically pushes the nozzle on the transfer assembly with the shifting rod 6. The nozzle then slides off the transfer assembly and finally falls onto the conveyor belt 2 via the inclined slide table 5. This process is significantly more efficient than manual disassembly and clamping. The assembly of the transfer components divides the interior of the housing 1 into four workstations: one clamping station, two grinding stations, and one unloading station. When one of the transfer components rotates and grinds the nozzle, the nozzle can be placed on the other three transfer components. Combined with the unloading components for unloading the nozzle, continuous polishing of the nozzle can be achieved, saving time spent manually stopping the machine to unload and install the nozzle. This is more conducive to polishing the nozzle during production and can improve processing efficiency. It should be noted that when installing the nozzle between the transfer components and the nozzle, an assembly arm can be installed on one side of the device to replace manual handling of the nozzle for installation and fixation. Since this is existing technology, it is only described in this solution and not shown.

[0040] like Figures 5 to 8As shown, the transfer assembly includes a positioning plate 8. One side of the positioning plate 8 can slide against the outer wall of the transfer box 4. A shaft 9 is fixedly installed on the other side of the positioning plate 8. Shaft discs 905 are symmetrically fixedly installed inside the shaft 9. Multiple support blocks 901 are slidably connected between the inner walls of the two shaft discs 905. Multiple return springs 902 are provided between one side of the multiple support blocks 901 and the inner wall of the shaft 9. The outer walls of the multiple support blocks 901 can contact the inner wall of the nozzle.

[0041] When it is necessary to fix the nozzle, the nozzle is inserted into the outside of the shaft 9. When one end of the nozzle contacts the positioning plate 8, multiple support blocks 901 inside the shaft 9 are pushed to move. When the support blocks 901 move inside the shaft 9, they will pull the return spring 902 to move outward along the opening direction of the shaft plate 905. The multiple support blocks 901 will expand outward by moving. When the outer walls of the multiple support blocks 901 all contact the inner wall of the nozzle, the multiple support blocks 901 will fix the nozzle to one side of the positioning plate 8 through external support, thus fixing the nozzle. At the same time, by pulling the return spring 902 outward within the shaft plate 905, the multiple support blocks 901 can fix various faucet nozzles of different diameters, increasing the applicability during operation.

[0042] like Figures 7 to 8 As shown, a fixed tube motor 903 is fixedly installed on the inner wall of the shaft 9. A round shaft 904 is fixedly installed on both output ends of the fixed tube motor 903. Push rods 907 are symmetrically fixedly installed on the outer walls of multiple support blocks 901. One end of each push rod 907 is opened as an inclined surface. Multiple rotating rods 906 are fixedly installed on the outer walls of the two round shafts 904. The outer walls of the multiple rotating rods 906 can be slidably connected to the outer walls of the multiple push rods 907 respectively.

[0043] When the support block 901 needs to be moved, the drive tube motor 903 drives the round shaft 904 to rotate. The round shaft 904 then drives multiple rotating rods 906 to rotate. When the rotating rods 906 rotate, they press against multiple push rods 907. The multiple push rods 907 are then pressed and push the support block 901 to pull the return spring 902 outward, thus causing the support block 901 to expand outward. When the nozzle is fixed, the drive tube motor 903 is reversed, the rotating rods 906 are reset, the push rods 907 lose their thrust, and the return spring 902 causes the support block 901 to retract into the infeed rod 9 for reset, providing a clamping base for the next clamping and providing pushing power for the movement of the support block 901.

[0044] like Figures 4 to 9As shown, a rotary motor 10 is fixedly installed on the inner wall of the rotary box 4. A rotating shaft 7 is fixedly installed on one output end of the rotary motor 10. The top of the rotating shaft 7 is rotatably connected to the inner wall of the rotary box 4. Four connecting shafts 701 are fixedly installed on the outer wall of the rotating shaft 7. Four sets of rotating components are respectively set on one side of the four connecting shafts 701.

[0045] When the nozzle is fixed in place by the external support blocks 901, the rotating shaft 7 is driven to rotate by the drive indexing motor 10. The rotating shaft 7 then drives the nozzle to rotate inside the housing 1 through the connecting shaft 701. This causes the indexing motor 10 to drive the nozzle from the clamping station through the grinding area and finally into the unloading station, thus playing the role of driving the nozzle to rotate. It should be noted that the indexing motor 10 is an intermittent rotating motor, and its rotation angle is always ninety degrees.

[0046] like Figures 3 to 4 As shown, two telescopic cylinders 301 are fixedly installed on the inner wall of the housing 1. The output ends of the two telescopic cylinders 301 are fixedly connected to the outer walls of the two sandblasting boxes 3 respectively. Both sandblasting boxes 3 can be placed outside the spray pipe.

[0047] When the indexing motor 10 moves the nozzle to below the sandblasting box 3, it drives the telescopic cylinder 301 to move the sandblasting box 3 downwards. The telescopic cylinder 301 then moves the sandblasting device 302 inside it towards the nozzle. When the sandblasting device 302 moves above the nozzle, the sandblasting box 3 completely covers the nozzle. The sandblasting device 302 then performs sandblasting on one side of the nozzle. With two sandblasting boxes 3, when one side of the nozzle is finished being sandblasted, the telescopic cylinder 301 is controlled to reset the sandblasting box 3. The drive indexing motor 10 moves the nozzle to the bottom of another sandblasting box 3. The other telescopic cylinder 301 then moves the sandblasting device 302 in the other sandblasting box 3 down to sandblast the other side of the nozzle, thereby achieving a comprehensive sandblasting operation on the nozzle and playing the role of sandblasting the faucet nozzle. It should be noted that when the nozzle is clamped and fixed between the nozzle and the transfer assembly, the nozzle should be placed horizontally. That is, when the water outlet of the nozzle is moved to the bottom of the sandblasting box 3, it should be in a horizontal position opposite to the position of the sandblasting box 3.

[0048] like Figures 5 to 9 As shown, a geared disc 401 is fixedly installed on the inner wall of the indexing box 4, and a ring shaft 802 is fixedly installed on the outer wall of the positioning plate 8. The outer wall of the ring shaft 802 is rotatably connected to the inner wall of the indexing box 4, and the inner wall of the ring shaft 802 can be rotatably connected to the inner wall of the connecting shaft 701. A geared ring 801 is fixedly installed on the outer wall of the ring shaft 802, and the teeth on the geared ring 801 can mesh with the teeth on the geared disc 401.

[0049] When the indexing motor 10 drives the rotating shaft 7 to rotate, the rotating shaft 7 will drive the positioning plate 8 to rotate through the connecting shaft 701. When the positioning plate 8 rotates, the toothed ring 801 on one side of the positioning plate 8 will automatically rotate along the tooth direction of the toothed disc 401. Thus, when the indexing motor 10 drives the nozzle to rotate, the toothed ring 801 drives the nozzle to rotate through the positioning plate 8. This makes it convenient for the nozzle to automatically flip over when it moves below the two sandblasting boxes 3, so that the two sandblasting devices 302 can perform sandblasting operations on both sides of the nozzle. It should be noted that the ratio of the number of teeth on the toothed ring 801 to the number of teeth on the toothed disc 401 that rotate 90 degrees should be 2:1.

[0050] like Figures 4 to 10 As shown, the unloading assembly also includes a moment rod 606. There are two moment rods 606 and two displacement rods 6. The two displacement rods 6 can be placed on one side of the nozzle. The top of each of the two displacement rods 6 is provided with a pusher block 602. Two sets of limiting plates 601 are symmetrically fixedly installed on the inner wall of the housing 1. The outer walls of the two displacement rods 6 are slidably connected to the inner walls of the two sets of limiting plates 601. The outer wall of the pusher block 602 can contact the outer wall of the nozzle.

[0051] When the indexing motor 10 drives the nozzle to rotate above the shifting rod 6, the fixed tube motor 903 is reversed, and the support block 901 will reset to unload the nozzle. Then, by pushing the torque rod 606, the torque rod 606 will drive the shifting rod 6 to slide between the two limit plates 601. The shifting rod 6 will drive the pusher block 602 to push the nozzle through the sliding block 5 and into the conveyor belt 2, thus pushing the nozzle to be picked up and unloaded. It should be noted that with the setting of two sets of unloading components, the unloading components can push the nozzle out and unload it regardless of the direction of the nozzle when it is placed, avoiding the phenomenon that the nozzle cannot be picked up and unloaded.

[0052] like Figures 9 to 10 As shown, two slot frames 609 are fixedly installed on the inner wall of the housing 1. Guide shafts 604 are fixedly installed on the inner wall of the slot frames 609. The outer walls of the two guide shafts 604 are slidably connected to the inner walls of the two displacement rods 6, respectively. The bottoms of the two displacement rods 6 are slidably connected to the tops of the two slot frames 609, respectively. A return spring 605 is provided between the inner walls of the two slot frames 609 and the outer walls of the two displacement rods 6. The two return springs 605 are respectively placed outside the two guide shafts 604.

[0053] When the push rod 606 moves the displacement rod 6, the displacement rod 6 will move at the top of the slot frame 609. The displacement rod 6 will then pull the return spring 605 to move on the guide shaft 604. When the pusher block 602 pushes the nozzle out of the shaft 9, it stops pushing the push rod 606. The return spring 605 will then elastically pull the displacement rod 6 to reset, providing a pushing basis for the next push of the nozzle, thus playing the role of resetting the displacement rod 6.

[0054] like Figures 9 to 10 As shown, the bottoms of the two push tube blocks 602 are respectively hinged to the tops of the two shift rods 6, and a pressure spring 603 is provided between one side of the two push tube blocks 602 and the outer wall of the two shift rods 6. The top side of the two push tube blocks 602 is opened as an inclined surface.

[0055] When the reset spring 605 pulls the shift rod 6 to reset, the shift rod 6 will drive the pusher block 602 to reset. Since the rotary motor 10 will drive the nozzle to rotate when the pusher block 602 resets, when the pusher block 602 resets and encounters the nozzle, when one side of the pusher block 602 contacts the outer wall of the nozzle, the nozzle will be limited and thus squeeze the pressure spring 603 at the top of the shift rod 6 to rotate. The pusher block 602 will then slide along the outer wall of the nozzle and eventually move to the other side of the nozzle, avoiding interference between the two during reset and playing the role of avoiding the nozzle during reset.

[0056] like Figures 9 to 10 As shown, four magnetic shielding arc plates 11 are fixedly installed at the other output end of the indexing motor 10. The bottom of the four magnetic shielding arc plates 11 is rotatably connected to the inner wall of the housing 1. An electromagnet 12 is fixedly installed on the inner wall of the indexing box 4. The four magnetic shielding arc plates 11 are respectively placed outside the electromagnet 12. A slot box 607 is fixedly installed between the two rods 606. A magnetic block 608 is fixedly installed on the inner wall of the slot box 607. The setting position of the magnetic block 608 corresponds to the setting position of the electromagnet 12. The outer wall of the slot box 607 is slidably connected to the inner wall of the housing 1.

[0057] When the indexing motor 10 drives the nozzle to rotate, the indexing motor 10 will also drive the magnetic shielding arc plate 11 to rotate. The indexing motor 10 will rotate outside the electromagnet 12. When the nozzle rotates above the shift rod 6, the magnetic shielding arc plate 11 will stop blocking the electromagnet 12. The electromagnet 12 will then push the magnetic block 608 to move through the magnetism. The magnetic block 608 will then drive the two rods 606 to move through the slot box 607, thereby providing power for the movement of the shift rod 6. The purpose of this arrangement is that when the nozzle rotates above the shift rod 6, the electromagnet 12 can directly push the magnetic block 608 to move through the opening between the two magnetic shielding arc plates 11, so that the shift rod 6 can push the nozzle immediately, reducing the time required for the power source to be turned on and off, and making it more convenient for the processing of the nozzle. It should be noted that except for the magnetic block 608, all other materials are made of magnetic shielding material.

[0058] Working principle: When polishing is required for the faucet nozzle, the nozzle is inserted into the transfer assembly on one side of the inverter box 4. The transfer assembly then automatically clamps and fixes the nozzle. After the nozzle is fixed, the transfer assembly rotates the nozzle through two sandblasting boxes 3 within the housing 1. The sandblasting device 302 inside the sandblasting box 3 performs sandblasting on the nozzle, thus polishing it. After polishing, the transfer assembly continues to rotate the nozzle. When the nozzle moves above the unloading assembly, the unloading assembly automatically pushes the nozzle on the transfer assembly with the shift rod 6. It will slide out from the transfer assembly and finally fall into the conveyor belt 2 via the inclined slide table 5. Compared with manual disassembly and clamping, the internal of the machine housing 1 can be divided into four workstations by setting up four sets of transfer assemblies, namely one clamping workstation, two grinding workstations and one unloading workstation. When one of the transfer assemblies drives the nozzle to rotate and grind, the nozzle can be placed on the other three sets of transfer assemblies by its rotation. With the help of the unloading assembly to unload the nozzle, the continuous polishing and grinding operation of the nozzle can be realized. This can save some time for manual stopping to unload and install the nozzle, and is more conducive to polishing and grinding the nozzle during processing and production, which can improve the processing efficiency.

[0059] When it is necessary to fix the nozzle, the nozzle is inserted into the outside of the shaft 9. When one end of the nozzle contacts the positioning plate 8, multiple support blocks 901 inside the shaft 9 are pushed to move. When the support blocks 901 move inside the shaft 9, they will pull the return spring 902 to move outward along the opening direction of the shaft plate 905. The multiple support blocks 901 will expand outward by moving. When the outer walls of the multiple support blocks 901 all contact the inner wall of the nozzle, the multiple support blocks 901 will fix the nozzle to one side of the positioning plate 8 through external support, thus fixing the nozzle. At the same time, by pulling the return spring 902 outward within the shaft plate 905, the multiple support blocks 901 can fix various faucet nozzles of different diameters, increasing the applicability during operation.

[0060] When it is necessary to move the support block 901, the drive tube motor 903 drives the round shaft 904 to rotate. The round shaft 904 then drives multiple rotating rods 906 to rotate. When the rotating rods 906 rotate, they press against multiple push rods 907. The multiple push rods 907 are then pressed and push the support block 901 to pull the return spring 902 outward, thereby causing the support block 901 to expand outward. When the nozzle is fixed, the drive tube motor 903 is reversed, the rotating rods 906 are reset, the push rods 907 lose their thrust, and the return spring 902 causes the support block 901 to retract into the infeed rod 9 for reset, providing a clamping base for the next clamping and providing pushing power for the movement of the support block 901.

[0061] When the nozzle is fixed by the external support of multiple support blocks 901, the rotating shaft 7 is driven to rotate by the drive indexing motor 10. The rotating shaft 7 will then drive the nozzle to rotate inside the housing 1 through the connecting shaft 701. Thus, the indexing motor 10 drives the nozzle from the clamping station through the grinding area and finally into the unloading station, which plays the role of driving the nozzle to rotate.

[0062] When the indexing motor 10 moves the nozzle to below the sandblasting box 3, the telescopic cylinder 301 drives the sandblasting box 3 to move downward. The telescopic cylinder 301 then drives the sandblasting device 302 inside it to move towards the nozzle. When the sandblasting device 302 moves above the nozzle, the sandblasting box 3 completely covers the nozzle. Then, the sandblasting device 302 performs sandblasting and polishing on one side of the nozzle. With the setting of two sandblasting boxes 3, when the polishing of one side of the nozzle is finished, the telescopic cylinder 301 is controlled to drive the sandblasting box 3 to reset. Then, the indexing motor 10 drives the nozzle to move to below the other sandblasting box 3. The other telescopic cylinder 301 then drives the sandblasting device 302 inside the other sandblasting box 3 to move down and perform sandblasting and polishing on the other side of the nozzle, thereby achieving a comprehensive sandblasting and polishing operation on the nozzle, which serves the purpose of sandblasting and polishing the faucet nozzle.

[0063] When the indexing motor 10 drives the rotating shaft 7 to rotate, the rotating shaft 7 will drive the positioning plate 8 to rotate through the connecting shaft 701. When the positioning plate 8 rotates, the toothed ring 801 on one side of the positioning plate 8 will automatically rotate along the tooth direction of the toothed disc 401. Thus, when the indexing motor 10 drives the nozzle to rotate, the toothed ring 801 drives the nozzle to rotate through the positioning plate 8. This makes it convenient for the nozzle to automatically flip over when it moves below the two sandblasting boxes 3, so that the two sandblasting devices 302 can perform sandblasting operations on both sides of the nozzle, thereby playing the role of automatically flipping the nozzle.

[0064] When the indexing motor 10 drives the nozzle to rotate above the shifting rod 6, the fixed tube motor 903 is reversed by controlling the support block 901 to reset and unload the nozzle. Then, the torque rod 606 is pushed to move, and the torque rod 606 will drive the shifting rod 6 to slide between the two limit plates 601. The shifting rod 6 will drive the pusher block 602 to push the nozzle through the sliding block 5 and fall into the conveyor belt 2, thus playing the role of pushing the nozzle to be picked up and unloaded.

[0065] When the push rod 606 moves the displacement rod 6, the displacement rod 6 will move at the top of the slot frame 609. The displacement rod 6 will then pull the return spring 605 to move on the guide shaft 604. When the push block 602 pushes the nozzle out of the shaft 9, it stops pushing the push rod 606. The return spring 605 will then elastically pull the displacement rod 6 to reset, providing a pushing basis for the next push of the nozzle, and playing the role of resetting the displacement rod 6.

[0066] When the reset spring 605 pulls the shift rod 6 to reset, the shift rod 6 will drive the pusher block 602 to reset. Since the rotary motor 10 will drive the nozzle to rotate when the pusher block 602 resets, when the pusher block 602 resets and encounters the nozzle, when one side of the pusher block 602 contacts the outer wall of the nozzle, the nozzle will be limited and thus squeeze the pressure spring 603 at the top of the shift rod 6 to rotate. The pusher block 602 will then slide along the outer wall of the nozzle and eventually move to the other side of the nozzle, avoiding interference between the two during reset and playing the role of avoiding the nozzle during reset.

[0067] When the indexing motor 10 drives the nozzle to rotate, the indexing motor 10 will also drive the magnetic shielding arc plate 11 to rotate. The indexing motor 10 will rotate outside the electromagnet 12. When the nozzle rotates above the shift rod 6, the magnetic shielding arc plate 11 will stop blocking the electromagnet 12. The electromagnet 12 will then push the magnetic block 608 to move through the magnetism. The magnetic block 608 will then drive the two rods 606 to move through the slot box 607, thereby providing power for the movement of the shift rod 6. The purpose of this arrangement is that when the nozzle rotates above the shift rod 6, the electromagnet 12 can directly push the magnetic block 608 through the opening between the two magnetic shielding arc plates 11, so that the shift rod 6 can push the nozzle immediately, reducing the time required for the power source to be turned on and off, and making it more convenient for the processing of the nozzle.
