Description

Technical Field

[0001] This invention relates to the field of sandblasting technology, and in particular to a dual-system integrated high-efficiency sandblasting machine. Background Technology

[0002] In the manufacturing process of cookware, surface sandblasting is an important process to improve the rust resistance, adhesion and aesthetics of the product. At the same time, before the sandblasting process, the surface of the cookware must be cleaned. However, the existing cleaning process is not well connected with the sandblasting process, which affects the overall production rhythm and the system integration is low. In addition, traditional sandblasting equipment mostly adopts a single sandblasting system with a fixed spray gun structure, which has the following technical defects: (1) The single frame and single station design leads to low production efficiency and is difficult to match the needs of large-scale production; (2) The spray gun angle is fixed and lacks multi-dimensional movement, resulting in uneven spraying effect; (3) The manual loading and unloading mode has safety hazards and restricts the level of automation.

[0003] Therefore, there is an urgent need to develop an integrated sandblasting equipment that combines high efficiency, high uniformity, and high degree of automation. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a dual-system integrated high-efficiency sandblasting machine.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A dual-system integrated high-efficiency sandblasting machine includes two sandblasting machine frames spaced apart. A rotating frame is horizontally rotatably mounted on the upper end of each of the two frames. Three sets of self-rotating cookware fixing assemblies are evenly distributed along the circumference of the lower side of each rotating frame. These cookware fixing assemblies are used to fix the cookware and position its opening downwards. The machine also includes a feeding device, a sandblasting device, and a discharging device arranged around the rotating frames and corresponding to the three sets of cookware fixing assemblies. A discharge device is provided on one side of each of the two feeding devices. The discharge device is used to orderly convey the cookware to be sandblasted to the feeding device. The device includes a lifting base that can move up and down. Two horizontal shafts are spaced apart on the lifting base. Spray guns are connected to each of the two horizontal shafts via transmission components. The nozzles of the two spray guns are inclined upwards and combined into a V-shape. When the lifting base moves the spray guns upwards and extends into the cookware, the transmission components can drive the two spray guns to slide back and forth along the horizontal shafts and drive the two spray guns to swing inwards relative to each other. An automatic rotating device is also provided on the sandblasting machine frame. The automatic rotating device is used to drive the cookware fixing component located above the sandblasting device to rotate. A finished product collection conveyor belt is provided between the two feeding devices.

[0007] In some embodiments, the sandblasting machine frame further includes a sandblasting chamber, the sandblasting device is located inside the sandblasting chamber, and a funnel-shaped recovery box is provided at the lower end of the sandblasting chamber.

[0008] In some embodiments, a first lifting cylinder is provided on the funnel-shaped recycling box, a connecting rod is provided on the piston rod of the first lifting cylinder, the lifting seat is provided on the connecting rod, the transmission assembly includes a rotating sleeve rotatably sleeved on a transverse shaft, a sliding sleeve sliding along its axial direction on the rotating sleeve, an upwardly extending long rod provided on the sliding sleeve, a spray gun being provided at the upper end of the long rod, a first vertical plate being provided on the funnel-shaped recycling box and located between the two transverse shafts, a transverse square shaft being provided on the lifting seat and located between the two transverse shafts, a sliding block being slidably sleeved on the transverse square shaft, slots being provided on both sides of the sliding block, a protruding ring being provided on the outer wall of both sliding sleeves, the protruding ring being correspondingly located in the slot, a guide post being provided on the sliding block, a wavy track groove being provided on one side of the first vertical plate, and one end of the guide post being located in the wavy track groove.

[0009] In some embodiments, a torsion spring and a limiting plate are provided on the transverse axis, and an extension plate is provided on the rotating sleeve. One end of the torsion spring is connected to the transverse axis, and the other end is connected to the extension plate. Under the action of the torsion spring, the extension plate is kept against the lower side of the limiting plate. When the extension plate is kept against the lower side of the limiting plate, the long rod is kept in an upward vertical state. A second vertical plate is provided on the funnel-shaped recycling box. A baffle is provided at the upper end of the second vertical plate and directly above the extension plate. When the extension plate moves upward, it can abut against the baffle, and the baffle restricts the extension plate from rising, so that the rotating sleeve rotates around the transverse axis.

[0010] In some embodiments, the cookware fixing assembly includes a plurality of rotating vertical cylinders rotatably mounted on the rotating frame. The rotating vertical cylinders are hollow, with an air source connected to the upper end via a rotary joint, and a suction cup provided at the lower end.

[0011] In some embodiments, a first motor for driving the rotating frame to rotate is also provided on the sandblasting machine frame. The automatic rotating device includes a second motor provided on the sandblasting machine frame. A drive wheel is provided on the output shaft of the second motor. A plurality of tension wheels are provided on the sandblasting machine frame. A drive belt is sleeved between the drive wheel and the plurality of tension wheels. A driven wheel is provided at the upper end of each of the rotating vertical cylinders. The driven wheel located at the work station of the sandblasting device can contact and abut against the drive belt and can drive the driven wheel to rotate through the drive belt.

[0012] In some embodiments, the feeding device includes a feeding platform with a plurality of feeding and conveying stations spaced apart on the feeding platform. Each feeding and conveying station includes a first conveyor belt line spaced apart. A second lifting cylinder is also provided on the feeding platform. A parallel double-headed cylinder is provided on the piston rod of the second lifting cylinder and located between the two first conveyor belt lines. Limiting seats are provided on both piston rods of the parallel double-headed cylinder, and limiting pins are spaced apart on the two limiting seats.

[0013] In some embodiments, the discharge device includes a first feeding conveyor belt and a second feeding conveyor belt connected in sequence. The first feeding conveyor belt is connected to one side of the feeding platform, and feeding channels corresponding to the feeding stations are provided at intervals on the first feeding conveyor belt. A swing channel is provided on the second feeding conveyor belt, and the swing channel transports the cookware one by one into the feeding channel by swinging.

[0014] In some embodiments, the feeding device includes a discharge conveyor belt, the end of which is connected to a finished product collection conveyor belt.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. By symmetrically arranging the double sandblasting frame and supporting equipment, the two sets of cooking utensils can simultaneously carry out the loading-sandblasting-unloading cycle operation, which increases the production capacity by 100% compared with the traditional single-machine system. At the same time, the three-station evenly distributed design of the rotating frame forms a continuous assembly line operation mode.

[0017] 2. The dual-rack interval layout ensures independent working space while sharing the central finished product conveyor belt; the distribution of the three sets of cooking utensils fixing components optimizes space utilization, reducing the floor space by 30% compared to the traditional straight-line arrangement.

[0018] 3. By setting up a discharge device on one side of the feeding device, and connecting the other end of the discharge device to the cleaning process, the cookware can be immediately conveyed to the sandblasting machine for sandblasting after cleaning, realizing automatic feeding-loading-sandblasting-unloading, forming a closed-loop material flow. In conjunction with the finished product centralized conveyor belt, the cookware is sandblasted in an inverted state. In this way, the residual sand will fall off naturally under the action of gravity during the sandblasting process and will not remain inside the cookware. Thus, there is no need to clean the cookware to remove the sand after sandblasting, reducing manual intervention by 80% and saving 3-4 operators per shift.

[0019] 4. In addition, during sandblasting, as the spray gun rises with the lifting platform, the nozzle of the spray gun is tilted upwards, which allows it to spray the inner wall of the cookware. When it rises a certain distance, the transmission component can drive the two spray guns to swing inwards relative to each other, thereby spraying the inner bottom wall of the cookware. Combined with the fact that the spray gun can slide back and forth along the horizontal axis, the efficiency and quality of the spraying are greatly improved. Attached Figure Description

[0032] The following detailed description provides various embodiments or examples for carrying out the present invention. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of the invention and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0033] like Figures 1-12 The illustrated dual-system integrated high-efficiency sandblasting machine includes two sandblasting machine frames 1 spaced apart. A rotating frame 2 is horizontally rotatably mounted on the upper end of each of the two sandblasting machine frames 1. Three sets of self-rotating cookware fixing assemblies are evenly distributed along the circumference of the lower side of each rotating frame 2. These cookware fixing assemblies are used to fix cookware 100 and ensure the opening of the cookware 100 faces downwards. The machine also includes a feeding device 3, a sandblasting device 4, and a discharging device 5, arranged around the rotating frame 2 and corresponding to the three sets of cookware fixing assemblies. A discharge device 6 is provided on one side of each of the two feeding devices 3. The discharge 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 base 7 that can be raised and lowered. Two horizontal shafts 10 are spaced apart on the lifting base 7. Spray guns 8 are connected to each of the two horizontal shafts 10 through a transmission assembly. The nozzles 9 of the two spray guns 8 are inclined upward and combined into a V-shape. When the lifting base 7 moves the spray guns 8 upward and extends into the cookware 100, the two spray guns 8 can be driven to slide back and forth along the horizontal shafts 10 and to swing inward relative to each other through the transmission assembly. An automatic rotating device 11 is also provided on the sandblasting machine frame 1. The automatic rotating device 11 is used to drive the cookware fixing assembly located above the sandblasting device 4 to rotate. A finished product centralized conveyor belt 12 is provided between the two feeding devices 5.

[0034] Based on the above structure, by symmetrically arranging the double sandblasting frame and supporting devices, the two sets of cooking utensils can simultaneously carry out the loading-sandblasting-unloading cycle operation, which increases the production capacity by 100% compared with 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.

[0035] The dual-rack, spaced-out layout ensures independent working space while sharing the central finished product conveyor belt 12; the distribution of the three sets of cooking appliance fixing components optimizes space utilization, reducing the floor space by 30% compared to the traditional straight-line arrangement.

[0036] By setting a discharge device 6 on one side of the feeding device 3, and connecting the other end of the discharge device 6 to the cleaning process 200 through the feeding conveyor 300, the cookware 100 can be immediately conveyed to the sandblasting machine for sandblasting after cleaning, realizing automatic feeding-loading-sandblasting-unloading, forming a closed-loop material flow. In conjunction with the finished product centralized conveyor belt 12, the cookware 100 is sandblasted in an inverted state. In this way, the residual sand will fall off naturally under the action of gravity during the sandblasting process and will not remain inside the cookware. Thus, there is no need to clean the cookware to remove the sand after sandblasting, reducing manual intervention by 80% and saving 3-4 operators per shift.

[0037] In addition, during sandblasting, as the spray gun 8 rises with the lifting seat 7, the nozzle 9 of the spray gun 8 extends upward at an angle, thus enabling the spraying of the inner wall of the cookware 100. When it rises a certain distance, the two spray guns 8 can be driven to swing inward relative to each other through the transmission component, thereby enabling the spraying of the inner bottom wall of the cookware 100. Combined with the fact that the spray gun 8 can slide back and forth along the transverse axis 10, the efficiency and quality of the spraying are greatly improved.

[0038] See Figure 2 , Figure 3 As shown, the sandblasting machine frame 1 also includes a sandblasting chamber 21, and the sandblasting device 4 is located inside the sandblasting chamber 21. A funnel-shaped recovery box 22 is provided at the lower end of the sandblasting chamber 21. The entire sandblasting operation is completed inside the sandblasting chamber 31, which can effectively prevent sand from spreading into the environment. In addition, since the cookware 100 is fixed upside down at the lower end of the cookware fixing assembly, the spray gun 8 sandblasts the cookware 100 from bottom to top. After the sand comes into contact with the cookware 100, it will naturally fall into the funnel-shaped recovery box 22 for recovery and will not remain inside the cookware 1. In this way, the time for cleaning the residual sand inside the cookware 100 can be saved after sandblasting is completed, further improving production efficiency.

[0039] See Figure 1-2 , Figures 10-12 As shown, the feeding device 3 includes a feeding platform 81, on which multiple feeding and conveying stations are arranged at intervals. Each feeding and conveying station includes a first conveyor belt 82 arranged at intervals. A second lifting cylinder 83 is also provided on the feeding platform 81. A parallel double-headed cylinder 84 is provided on the piston rod of the second lifting cylinder 83 and located between the two first conveyor belts 82. Limiting seats 85 are provided on both piston rods of the parallel double-headed cylinder 84, and limiting pins 86 are spaced apart on the two limiting seats 85.

[0040] The discharge device 6 includes a first feeding conveyor belt 91 and a second feeding conveyor belt 92 connected in sequence. The first feeding conveyor belt 91 is connected to one side of the feeding platform 81, and feeding channels 94 corresponding to the feeding stations are provided at intervals on the first feeding conveyor belt 91. A swing channel 93 is oscillatingly provided on the second feeding conveyor belt 92. The swing channel 93 transports the cookware 100 one by one into the feeding channel 94 by swinging.

[0041] A feeding conveyor 300 is connected between the cookware cleaning process 200 and the discharge device 6. After the cookware surface pretreatment is completed, it can be placed upside down on the feeding conveyor 300. The feeding conveyor 300 transports the cookware 100 to the second feeding conveyor belt 92 of the discharge device 6. Then, the swing channel 93 sequentially transports the cookware 100 one by one to multiple feeding channels 94 on the first feeding conveyor belt 91. The cookware 100 in the multiple feeding channels 94 enters the first feeding device 3 one by one. On the conveyor belt 82, when the cookware 100 is conveyed to the designated position on the first conveyor belt 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 limiting seat 85 to retract into each other. Finally, the limiting pin 86 on the limiting seat 85 limits and fixes the cookware 100. 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, allowing the suction cup 62 to adhere.

[0042] See Figures 1-2 As shown, the feeding device 5 includes a discharge conveyor belt 95. The end of the discharge conveyor belt 95 is connected to the finished product collection conveyor belt 12. When the coated cookware 100 is transported to the bottom of the discharge conveyor belt 95, the suction cup 62 cuts off the air supply. The cookware 100 falls off the discharge conveyor belt 95 under its own weight and is then transported by the discharge conveyor belt 95 to the finished product collection conveyor belt 12 for collection.

[0043] See Figures 6-9 As shown, a first lifting cylinder 31 is provided on the funnel-shaped recycling box 22, and a connecting rod 32 is provided on the piston rod of the first lifting cylinder 31. The lifting seat 7 is provided 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 along the axial direction on the rotating sleeve 33. An upwardly extending long rod 35 is provided on the sliding sleeve 34. The spray gun 8 is provided at the upper end of the long rod 35.

[0044] Furthermore, a first vertical plate 41 is provided on the funnel-shaped recycling box 22 and located between the two horizontal axes 10, and a horizontal square shaft 42 is provided on the lifting seat 7 and located between the two horizontal axes 10. A sliding block 43 is slidably sleeved on the horizontal square shaft 42. A groove 44 is provided on both sides of the sliding block 43. A convex ring 45 is provided on the outer wall of both sliding sleeves 34. The convex ring 45 is correspondingly provided in the groove 44. A guide post 46 is provided on the sliding block 43. A wave-shaped track groove 47 is provided on one side of the first vertical plate 41. One end of the guide post 46 is provided in the wave-shaped track groove 47.

[0045] 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 against the lower side of the limiting plate 52. When the extension plate 53 is kept 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 recycling box 22. A baffle 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 55, and the baffle 55 restricts the extension plate 53 from rising, so that the rotating sleeve 33 rotates around the transverse shaft 10.

[0046] The specific operating principle of spray gun 8 is as follows:

[0047] When the cookware fixing assembly on the rotating frame 2 drives the cookware 100 into the sandblasting device 4 of the sandblasting chamber 21, the first lifting cylinder 31 drives the lifting seat 7 to rise, and at the same time the spray gun 8 rises into the cookware 100, and sprays the inner wall of the cookware 100 through the spray gun 8 (e.g., Figure 7 As 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 axis 42. The convex ring 45 on the outer wall of the sliding sleeve 34 is located in the groove 44 of the sliding block 43. Thus, with the cooperation of the convex ring 45 and the groove 44, the sliding sleeve 34 is simultaneously driven to slide back and forth, thereby enabling the spray gun 8 to slide back and forth while rising and falling. In addition, when the lifting seat 7 and the spray gun 8 rise and fall, 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 axis 42. After the seat 7 and spray gun 8 rise a certain distance, when the extension plate 53 on the rotating sleeve 33 abuts against the baffle 55, the extension plate 53 is pressed down by the baffle 55 as the lifting seat 7 and spray gun 8 continue to rise. At this time, the rotating sleeve 33 rotates in the transverse axis 10, thereby driving the sliding sleeve 34, the long rod 35 and the spray gun 8 to rotate synchronously. The long rod 35 and the spray gun 8 on both sides swing inward towards each other, thereby spraying the inner bottom wall of the cookware 100, greatly improving the efficiency and quality of spraying.

[0048] See Figures 2-5 As shown, the cookware fixing assembly includes several rotating vertical cylinders 61 rotatably mounted on the rotating frame 2. The rotating vertical cylinders 61 are hollow structures, with an air source connected to the upper end through a rotating joint, and a suction cup 62 provided at the lower end. The suction cup 62 is used to adhere and fix the outer bottom wall of the cookware 100.

[0049] Furthermore, a first motor 71 for driving the rotating frame 2 to rotate is also provided on the sandblasting machine frame 1. The automatic rotating device 11 includes a second motor 72 provided on the sandblasting machine frame 1. A drive wheel 73 is provided on the output shaft of the second motor 72. A plurality of tension wheels 74 are provided on the sandblasting machine frame 1. A drive belt 75 is sleeved between the drive wheel 73 and the plurality of tension wheels 74. A driven wheel 76 is provided at the upper end of each of the rotating vertical cylinders 61. The driven wheel 76 located at the work position of the sandblasting device 4 can contact and abut against the drive belt 75 and can be driven to rotate by the drive belt 75.

[0050] When the first motor 71 is working, it drives the rotating frame 2 to rotate, thereby causing the three sets of cookware fixing components to circulate and transport in the three workstations of the feeding device 3, the sandblasting device 4, and the unloading device 5. When the second motor 72 is working, it drives the drive belt 75 to rotate in cooperation with the drive wheel 73 and several tensioning wheels 74. When the driven wheel 76 abuts against the drive belt 75, it drives the driven wheel 76 to rotate under the action of friction, thereby driving the rotating vertical cylinder 61 to rotate.
