[0033] The following specific implementation content provides various different embodiments or examples for implementing the present invention. Of course, these are only embodiments or examples and are not intended to be restrictive. Additionally, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the present invention and do not represent a specific relationship between the different embodiments and / or structures being discussed.

[0034] As Figure 1-Figure 12 shown, a dual-system integrated high-efficiency sandblasting machine includes two spaced sandblasting machine frames 1. At the upper ends of both sandblasting machine frames 1, a rotating frame 2 is horizontally rotatably installed. Along the circumference on the lower side of the rotating frame 2, three groups of cookware fixing components capable of self-rotation are evenly distributed. The cookware fixing components are used to fix the cookware 100 and make the opening of the cookware 100 face downward. It further includes a feeding device 3, a sandblasting device 4, and a discharging device 5 that are arranged around the rotating frame 2 and correspond to the lower sides of the three groups of cookware fixing components. On one side of both feeding devices 3, a discharging device 6 is provided. The discharging device 6 is used to orderly convey the cookware 100 to be sandblasted to the feeding device 3. The sandblasting device 4 includes a lifting seat 7 capable of moving up and down. On the lifting seat 7, two transverse shafts 10 are spaced apart. On both transverse shafts 10, spray guns 8 are respectively connected through transmission components. The nozzles 9 of both spray guns 8 extend obliquely upward and are combined in a V shape. When the lifting seat 7 drives the spray guns 8 to move upward and extend into the cookware 100, the two spray guns 8 can be driven to slide back and forth along the transverse shafts 10 and swing inwardly towards each other through the transmission components. An automatic rotating device 11 is further provided on the sandblasting machine frame 1. The automatic rotating device 11 is used to drive the cookware fixing components located above the sandblasting device 4 to rotate. A finished product centralized conveyor belt 12 is provided between the two discharging devices 5.

[0035] According to the above structure, by symmetrically arranging the dual sandblasting machine frames and supporting devices, the two groups of cookware 100 can perform the feeding-sandblasting-discharging cyclic operation synchronously, with the production capacity increased by 100% compared to the traditional single-machine system. At the same time, through the three-station evenly distributed design of the rotating frame 2, a continuous assembly line operation mode is formed.

[0036] The dual-frame spaced layout not only ensures an independent operation space but also shares the central finished product centralized conveyor belt 12; the distribution of the three groups of cookware fixing components optimizes the space utilization rate, reducing the floor area by 30% compared to the traditional linear arrangement scheme.

[0037] By arranging a discharging device 6 on one side of the feeding device 3, and connecting the other end of the discharging device 6 to the cleaning process 200 through a feeding conveyor 300, after the cooking utensil 100 is cleaned, it can be immediately conveyed to the sandblasting machine for sandblasting work, realizing automatic feeding - loading - sandblasting - unloading, forming a closed-loop material flow, cooperating with the finished product centralized conveyor belt 12. In addition, the cooking utensil 100 is sandblasted in an inverted state, so that the residual sand during the sandblasting process will naturally fall under the action of gravity and will not remain inside the cooking utensil. Thus, it is not necessary to clean the cooking utensil to remove the sand after sandblasting, reducing the manual intervention link by 80%, and 3 - 4 operators can be saved per single shift.

[0038] In addition, during the sandblasting work, when the spray gun 8 rises following the lifting seat 7, since the nozzle 9 of the spray gun 8 extends obliquely upward, the inner side wall of the cooking utensil 100 can be sprayed. When it rises a certain distance, the two spray guns 8 can be driven by the transmission component to swing inwardly towards each other, so that the inner bottom wall of the cooking utensil 100 can be sprayed. Combined with the fact that the spray gun 8 can slide back and forth along the transverse axis 10, the spraying efficiency and quality are greatly improved.

[0039] See Figure 2 、 Figure 3 As shown in the figure, the sandblasting machine frame 1 further includes a sandblasting chamber 21, the sandblasting device 4 is arranged in the sandblasting chamber 21, and a funnel-shaped recovery box 22 is arranged at the lower end of the sandblasting chamber 21. The entire sandblasting operation is completed in the sandblasting chamber 31, which can effectively prevent the sand from spreading into the environment. In addition, since the cooking utensil 100 is fixedly inverted at the lower end of the cooking utensil fixing component, the spray gun 8 sprays the cooking utensil 100 from bottom to top, and the sand will naturally fall into the funnel-shaped recovery box 22 for recovery after contacting the cooking utensil 100, and will not remain inside the cooking utensil 1. Thus, the time for cleaning the residual sand inside the cooking utensil 100 can be saved after sandblasting, further improving the production efficiency.

[0040] See Figure 1-2 、 Figure 10-12 As shown in the figure, the feeding device 3 includes a feeding table 81, and a plurality of feeding and conveying stations are arranged at intervals on the feeding table 81. The feeding and conveying stations include first conveying belt lines 82 arranged at intervals. A second lifting cylinder 83 is further arranged on the feeding table 81. A parallel double-headed cylinder 84 is arranged on the piston rod of the second lifting cylinder 83 and between the two first conveying belt lines 82. Limit seats 85 are arranged on the piston rods at both ends of the parallel double-headed cylinder 84, and limit pins 86 are arranged at intervals between the two limit seats 85.

[0041] The discharging device 6 includes a first feeding conveyor belt 91 and a second feeding conveyor belt 92 which are connected in sequence. The first feeding conveyor belt 91 is connected and arranged on one side of the feeding table 81, and feeding channels 94 corresponding to the feeding conveying stations are arranged at intervals on the first feeding conveyor belt 91. A swinging channel 93 is swingably arranged on the second feeding conveyor belt 92, and the swinging channel 93 conveys the cookware 100 into the feeding channels 94 one by one through swinging.

[0042] An inlet conveyor 300 is connected between the cookware cleaning process 200 and the discharging device 6. Thus, after the surface pretreatment of the cookware is completed, it can be directly placed upside down on the inlet conveyor 300. The inlet conveyor 300 conveys the cookware 100 to the second feeding conveyor belt 92 of the discharging device 6, and then the swinging channel 93 conveys the cookware 100 into the multiple feeding channels 94 on the first feeding conveyor belt 91 one by one. The cookware 100 in the multiple feeding channels 94 enters the first conveying belt line 82 of the feeding device 3 one by one. When the cookware 100 is conveyed to the designated position on the first conveying belt line 82, the second lifting cylinder 83 drives the parallel double-headed cylinder 84 to rise. Then, the piston rods at both ends of the parallel double-headed cylinder 84 drive the limit seats 85 to close to each other. Finally, the cookware 100 is limited and fixed by the limit pins 86 on the limit seats 85. Finally, the second lifting cylinder 83 continues to drive the parallel double-headed cylinder 84 and the cookware 100 to rise, so that the cookware 100 rises to the corresponding suction cup 62, and the suction cup 62 performs adsorption.

[0043] See Figure 1-Figure 2 As shown, the blanking device 5 includes a discharging conveyor belt 95. The end of the discharging conveyor belt 95 is connected to the finished product centralized conveyor belt 12. When the sprayed cookware 100 is conveyed below the discharging conveyor belt 95, the suction cup 62 cuts off the air supply, and the cookware 100 falls onto the discharging conveyor belt 95 under its own gravity, and the discharging conveyor belt 95 conveys the cookware 100 to the finished product centralized conveyor belt 12 for collection.

[0044] See Figure 6-Figure 9 As shown, a first lifting cylinder 31 is arranged on the funnel-shaped recycling box 22. A connecting rod 32 is arranged on the piston rod of the first lifting cylinder 31. The lifting seat 7 is arranged on the connecting rod 32. The transmission assembly includes a rotating sleeve 33 rotatably sleeved on the transverse shaft 10. A sliding sleeve 34 slides axially along the rotating sleeve 33. A long rod 35 extends upward on the sliding sleeve 34. The spray gun 8 is arranged at the upper end of the long rod 35. A reciprocating sliding assembly and a swinging assembly are also arranged on the funnel-shaped recycling box 22. When the lifting seat 7 moves up and down, the reciprocating sliding assembly can drive the sliding sleeve 34 to slide back and forth along the axial direction of the rotating sleeve 33 and drive the rotating sleeve 33 to rotate around the transverse shaft 10.

[0045] Further, the reciprocating sliding assembly includes a first vertical plate 41 disposed on the funnel-shaped recovery box 22 and located between the two transverse shafts 10. A transverse square shaft 42 is disposed on the lifting seat 7 and located between the two transverse shafts 10. A sliding block 43 is slidably sleeved on the transverse square shaft 42. Notch openings 44 are provided on both sides of the sliding block 43. Convex rings 45 are provided on the outer walls of the two sliding sleeves 34. The convex rings 45 are correspondingly disposed in the notch openings 44. A guiding column 46 is provided on the sliding block 43. A wavy track groove 47 is provided on one side of the first vertical plate 41. One end of the guiding column 46 is disposed in the wavy track groove 47.

[0046] A torsion spring 51 and a limiting plate 52 are provided on the transverse shaft 10. An extension plate 53 is provided on the rotating sleeve 33. One end of the torsion spring 51 is connected to the transverse shaft 10, and the other end is connected to the extension plate 53. Under the action of the torsion spring 51, the extension plate 53 is kept in abutment against the lower side of the limiting plate 52. And when the extension plate 53 is kept in abutment against the lower side of the limiting plate 52, the long rod 35 is kept in an upward vertical state. A second vertical plate 54 is provided on the funnel-shaped recovery box 22. A baffle plate 55 is provided at the upper end of the second vertical plate 54 and directly above the extension plate 53. When the extension plate 53 moves upward, it can abut against the baffle plate 55, and the upward movement of the extension plate 53 is restricted by the baffle plate 55, so that the rotating sleeve 33 rotates around the transverse shaft 10.

[0047] The specific movement principle of the spray gun 8 is as follows:

[0048] When the cooking utensil fixing assembly on the rotating frame 2 drives the cooking utensil 100 into the sandblasting device 4 in the sandblasting chamber 21, the first lifting cylinder 31 drives the lifting seat 7 to rise. At the same time, the spray gun 8 will rise into the cooking utensil 100, and the inner side wall of the cooking utensil 100 is sprayed through the spray gun 8 (such as Figure 7As shown, when the lifting seat 7 and the spray gun 8 rise, one end of the guide post 46 on the sliding block 43 moves within the wavy track groove 47. Under the action of the wavy track groove 47, the guide post 46 and the sliding block 43 slide back and forth in the transverse square shaft 42. The convex ring 45 on the outer wall of the sliding sleeve 34 is arranged in the notch 44 of the sliding block 43. Thus, with the cooperation of the convex ring 45 and the notch 44, the sliding sleeve 34 is driven to slide back and forth at the same time, and then the spray gun 8 realizes sliding back and forth while lifting. In addition, when the lifting seat 7 and the spray gun 8 rise a certain distance and the extension plate 53 on the rotating sleeve 33 abuts against the baffle 55, when the lifting seat 7 and the spray gun 8 continue to rise, the extension plate 53 presses the baffle 55 downward. At this time, the rotating sleeve 33 rotates in the transverse shaft 10, and then drives the sliding sleeve 34, the long rod 35 and the spray gun 8 to rotate synchronously through the rotating sleeve 33. The long rods 35 and the spray guns 8 on both sides swing inward relative to each other, and then the inner bottom wall of the cooking utensil 100 can be sprayed, greatly improving the spraying efficiency and quality.

[0049] See Figure 2-Figure 5 As shown, the cooking utensil fixing assembly includes a plurality of rotating vertical cylinders 61 rotatably arranged on the rotating frame 2. The rotating vertical cylinders 61 are of a hollow structure, and the upper end is connected to a gas source through a rotary joint, and the lower end is provided with a suction cup 62 to adsorb and fix the outer bottom wall of the cooking utensil 100 through the suction cup 62.

[0050] Further, a first motor 71 for driving the rotation of the rotating frame 2 is further arranged on the sandblasting machine frame 1. The automatic rotating part device 11 includes a second motor 72 arranged on the sandblasting machine frame 1. A driving wheel 73 is arranged on the output shaft of the second motor 72. A plurality of tension wheels 74 are arranged on the sandblasting machine frame 1. A driving belt 75 is sleeved together between the driving wheel 73 and the plurality of tension wheels 74. Driven wheels 76 are arranged at the upper ends of the rotating vertical cylinders 61. The driven wheel 76 located at the working station of the sandblasting device 4 can contact and abut against the driving belt 75 and can drive the driven wheel 76 to rotate through the driving belt 75.

[0051] When the first motor 71 works, it drives the rotation of the rotating frame 2, so that the three groups of cooking utensil fixing assemblies are circulated and conveyed at the three working stations of the feeding device 3, the sandblasting device 4 and the discharging device 5. When the second motor 72 works, with the cooperation of the driving wheel 73 and the plurality of tension wheels 74, it drives the driving belt 75 to rotate. When the driven wheel 76 abuts against the driving belt 75, it drives the driven wheel 76 to rotate under the action of friction, and then drives the rotating vertical cylinder 61 to rotate self - sufficiently.
