Description

Technical Field

[0001] The present invention relates to the technical field of surface painting, specifically to the surface painting process of stainless steel vacuum cups. Background Art

[0002] A stainless steel vacuum cup is a common container for keeping beverages warm. It is made of stainless steel material and can effectively maintain the temperature of the liquid, whether it is hot or cold. Its structure generally includes an inner and outer double-layer stainless steel, and a vacuum insulation layer is used to prevent heat loss or external heat from entering, so as to achieve the effect of heat preservation. In order to improve the aesthetics of the vacuum cup, its surface will be painted, and a painting device is required.

[0003] In the prior art, when painting the surface of a stainless steel vacuum cup, usually an artificial hand-held spray gun is used, and the stainless steel vacuum cup is placed on a rotating rack by hand. The stainless steel is fixed and rotated by the rotating rack, and the surface of the rotating stainless steel vacuum cup is evenly coated to complete the painting. However, when manually taking and placing, the hand directly touches the surface of the stainless steel vacuum cup, which will cause the painted area on the surface of the stainless steel vacuum cup to be contaminated with oil stains, etc. The attachment of stains or dust on the surface of the stainless steel vacuum cup will reduce the paint adhesion strength, resulting in problems such as swelling or paint peeling in the spraying area, thus affecting the painting effect.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, by wiping and cleaning the area to be polished of the stainless steel thermos cup with water or a cleaning agent, and fixing it through the fixing component, then driving the moving lead screw to rotate by the moving motor, the moving lead screw drives the driving block to move, the driving block drives the sleeve to move, the sleeve drives the sliding column to move, and the sliding column drives the stainless steel thermos cup to be painted to move horizontally through a plurality of anti-slip rubber pads. At the same time, under the action of the rotating rack and the self-rotating gear, the stainless steel thermos cup rotates while moving horizontally. When the painted area of the stainless steel thermos cup fits on the surface of the water-absorbing sponge, the painted area on the stainless steel surface is dried by absorbing water through the rotation of the stainless steel thermos cup in cooperation with the water-absorbing sponge, preventing water stains from remaining on the surface, achieving the effect of cleaning the surface of the stainless steel thermos cup, and avoiding the situation that the spraying surface is contaminated with stains due to direct feeding after hand contact, which affects the spraying quality.

[0021] 2. In the present invention, the output end of the driving motor drives the main gear disk to rotate, the main gear disk drives two sub-gear disks to rotate, and the two sub-gear disks respectively drive two driving racks to move. One of the driving strips drives two first-level driving rods to move, the two first-level driving rods respectively drive two first-level moving blocks to move, and the two first-level moving blocks respectively drive two cleaning frames to move away from each other. At the same time, the other driving strip drives two second-level moving blocks to move, so that the two second-level moving blocks respectively drive two grinding frames to move closer to each other. The two grinding frames drive the sandpapers to move closer to each other through the corresponding two rollers, so that the sandpapers are in the movement area of the stainless steel thermos cup, and the two sandpapers are attached to the painted area of the stainless steel thermos cup to appropriately polish the painted area of the stainless steel thermos cup, improving the adhesion of the paint layer during painting and further improving the quality of subsequent spraying.

[0022] 3. In the present invention, when the two cleaning racks move relative to each other, the first-stage moving gear cooperates with the first-stage moving rack to drive the water-absorbing sponge to rotate. When the water-absorbing sponge rotates, the scraper scrapes the surface of the water-absorbing sponge to scrape out the liquid adsorbed in the water-absorbing sponge and collect it into the collection dish. At the same time, the polishing rack drives the L-shaped rod to move through the second-stage moving gear, and the L-shaped rod drives the piston to move, so that the air purification box inhales the external air through the one-way suction nozzle. When the two polishing racks move away from each other, the polishing rack drives the roller to drive the second-stage moving gear to rotate under the action of the second-stage moving rack, so that the lower roller rotates to wind up the used sandpaper and load the unused sandpaper from the upper roller, improving the reuse rate of the water-absorbing sponge while automatically replacing the sandpaper to maintain its polishing effect.

[0035] The present invention will be further described below in conjunction with specific embodiments. However, those skilled in the art should understand that the detailed description given here in conjunction with the accompanying drawings is for better explanation. The structure of the present invention necessarily goes beyond these limited embodiments, and for some equivalent replacement schemes or common means, no detailed description will be given herein, but they still fall within the protection scope of this application.

[0036] Figures 1 to 9 This is the best embodiment of the present invention. The following will Figures 1 to 9 further describe the present invention.

[0037] As Figures 1 to 9 shown, the surface painting process of a stainless steel vacuum cup includes the following steps:

[0038] S1. First, wipe and clean the stainless steel vacuum cup with clean water or a cleaner to ensure the surface is clean. After cleaning, place the stainless steel vacuum cup upside down with the cup mouth on the fixing component;

[0039] S2. Then start the cleaning component to clean the stainless steel vacuum cup, and then start the polishing component to moderately polish the stainless steel vacuum cup;

[0040] S3. After polishing, spray paint on the surface of the stainless steel vacuum cup through the painting component to complete the painting process.

[0041] Further, in the processing step of S1, the fixing component includes an operating table 1. A moving groove is formed on the upper side of the operating table 1. A driving block 36 is slidably installed in the moving groove. A driving hole is formed on one side of the moving groove. A moving lead screw 14 is rotatably installed in the driving hole. The driving block 36 is screwed and installed on the surface of the moving lead screw 14. A rotating rack 13 is fixedly installed on the inner wall of the moving groove. A moving motor 38 is fixedly installed on one side of the operating table 1. The output shaft of the moving motor 38 is coaxially and fixedly connected to one end of the moving lead screw 14. A sleeve 39 is rotatably installed on the upper side of the driving block 36. A sliding column 44 is slidably installed in the inner wall of the sleeve 39. A plurality of secondary support rods 48 are rotatably installed on the surface of the sliding column 44. A plurality of primary support rods 45 are rotatably installed at the top end of the sleeve 39. One end of the primary support rod 45 and one end of the secondary support rod 48 are rotatably installed with the same connecting block 47. An anti-slip rubber pad 46 is fixedly installed on one side of the connecting block 47. A spring groove is formed on the inner bottom wall of the sleeve 39. A reset spring 42 is fixedly installed in the spring groove. The top end of the reset spring 42 is fixedly connected to the bottom end of the sliding column 44. A self-rotating gear 37 is fixedly installed on the surface of the sleeve 39. The rotating rack 13 meshes with the self-rotating gear 37. A baffle 2 is fixedly installed on the surface of the sleeve 39. A rubber block 43 is fixedly installed at the top end of the sliding column 44. An installation hole is formed on one side of the sleeve 39. An ejection unit is fixedly installed in the installation hole.

[0042] With the above structure, the fixing component is slidably installed on the moving groove through the driving block 36. When the two grinding frames 4 move away from each other, the one-way shaft provides driving force for the secondary moving gear 30. On the contrary, it will slip and the secondary moving gear 30 cannot rotate. There are four first-level support rods 45 and second-level support rods 48 in total. The first-level support rods 45 are installed at equal angular intervals at the top of the sleeve 39. By cooperating the first-level support rods 45 with the second-level support rods 48, the anti-slip rubber pad 46 is attached to the inner wall of the stainless steel thermos cup, and the stainless steel thermos cup is fixed by using the frictional force. At the same time, the anti-slip rubber pad 46 has a certain deformation ability. By using the deformation ability of the anti-slip rubber pad 46, the stainless steel thermos cup is further pressed down, so that the clamping block 49 extends into the sliding hole to complete the fixation of the stainless steel thermos cup. An annular groove is opened on the upper side of the baffle 2 to facilitate inserting and fitting the cup mouth to prevent the cup mouth from being painted. The top rubber block 43 can prevent the bottom of the cup from being damaged by hard contact with the top of the sliding column 44. The sliding column 44 is slidably installed on the inner wall of the sleeve 39, and a part of the movement area is reserved on one side of the clamping block 49 to provide a moving space for the clamping block 49. When the clamping block 49 is about to reach the sliding hole, the anti-slip rubber pad 46 has been attached to the inner wall of the stainless steel thermos cup. When the driving block 36 moves, the self-rotating gear 37 cooperates with the rotating rack 13 to realize self-rotation, so that the stainless steel thermos cup rotates during horizontal movement. The number of teeth of the rotating rack 13 and the number of teeth of the self-rotating gear 37 are such that when the stainless steel thermos cup moves to the cleaning area, grinding area, and painting area, the number of self-rotation circles exceeds one or more, ensuring that the working areas of all functional components completely cover the surface of the stainless steel thermos cup.

[0043] In the processing step of S2, the cleaning component includes a cleaning frame 3. Two sets of limiting ports 40 are opened on the upper side of the operating table 1. Each set of limiting ports 40 includes two symmetrically arranged ones. Two first-level moving blocks 22 are slidably installed in the two limiting ports 40 of one of the groups. A cleaning frame 3 is fixedly installed on the upper side of the first-level moving block 22. A water-absorbing sponge 18 is rotatably installed on the inner wall of the cleaning frame 3. A first-level moving gear 17 is fixedly installed at the bottom end of the water-absorbing sponge 18. A first-level moving rack 16 is fixedly installed on the upper side of the operating table 1. The first-level moving gear 17 meshes with the first-level moving rack 16. A liquid scraping unit is fixedly installed on the inner top wall of the cleaning frame 3.

[0044] With the above structure, the cleaning component includes two cleaning frames 3. The relevant components installed on each cleaning frame 3 are the same. The water-absorbing sponge 18 installed on the cleaning frame 3 is composed of a rotating shaft and a cylindrical sponge. When the two cleaning frames 3 approach each other, the water-absorbing sponge 18 can be attached to the painted area on the surface of the stainless steel thermos cup to absorb water and dry the stainless steel surface.

[0045] The liquid scraping unit includes a suspension rod 19, which is fixedly installed on the inner top wall of the cleaning rack 3. A scraper 20 is fixedly installed on the surface of the suspension rod 19. The scraper 20 is attached to the surface of the water-absorbing sponge 18. A collecting dish 21 is fixedly installed at the bottom end of the suspension rod 19.

[0046] With the above structure, the height of the scraper 20 is the same as that of the water-absorbing sponge 18. When the water-absorbing sponge 18 rotates, the scraper 20 will squeeze the water-absorbing sponge 18, thereby squeezing out the water absorbed inside the water-absorbing sponge 18 and maintaining the water absorption of the water-absorbing sponge 18.

[0047] In the processing step of S2, the grinding assembly includes two secondary moving blocks 23. The two secondary moving blocks 23 are respectively slidably installed in two limiting ports 40 of another group. A grinding frame 4 is fixedly installed on the upper side of the secondary moving block 23. Two winding rollers 28 are rotatably installed on the inner wall of the grinding frame 4. The same sandpaper 26 is sleeved on the surfaces of the two winding rollers 28. A secondary moving rack 24 is fixedly installed on the upper side of the operating table 1. A rotating hole is opened on one side of the grinding frame 4. A secondary moving gear 30 is rotatably installed in the rotating hole. The secondary moving gear 30 is engaged with the secondary moving rack 24. One side of the secondary moving gear 30 is fixedly connected to one side of one of the winding rollers 28 through a one-way shaft. A top plate 27 is fixedly installed on the inner wall of the grinding frame 4. The top plate 27 is attached to the back of the sandpaper 26. An impurity removing unit is fixedly installed on the upper side of the operating table 1.

[0048] With the above structure, the grinding assembly includes two grinding frames 4. The relevant components installed on the two grinding frames 4 are the same. Two winding rollers 28 are installed on the inner wall of the grinding frame 4. The upper winding roller 28 is wrapped with unused sandpaper 26, and the lower winding roller 28 is wrapped with used sandpaper 26. The secondary moving gear 30 is fixedly connected to the lower winding roller 28 through a one-way shaft.

[0049] The impurity removing unit includes an air impurity removing box 5 fixed on the operating table 1. A piston 33 is slidably installed on the inner wall of the air impurity removing box 5. An L-shaped rod 35 is fixedly installed on one side of the piston 33. The other end of the L-shaped rod 35 is rotatably installed on one side of the secondary moving gear 30. An air inlet hole is opened on one side of the air impurity removing box 5. A one-way suction nozzle 34 is fixedly installed in the air inlet hole. An air outlet hole is opened on one side of the air impurity removing box 5. An air pipe 31 is fixedly installed in the air outlet hole. A hollow pipe 25 is fixedly installed on one side of the air impurity removing box 5. An air jet port is opened on one side of the hollow pipe 25. An air nozzle 32 is fixedly installed in the air jet port. A conveying hole is opened on one side of the hollow pipe 25. The other end of the air pipe 31 is fixedly installed in the conveying hole. A one-way valve 29 is installed on the air pipe 31.

[0050] With the above structure, the inner wall of the air pipe 31 installed on one side of the hollow pipe 25 gradually decreases in cross-section from the inside to the outside, which enhances the wind force intensity during blowing and blows and cleans the surface of the polished heat-insulated cup. The direction of the one-way suction nozzle 34 installed on one side of the air impurity removal box 5 is from the outside to the inside of the air impurity removal box 5, and the one-way valve 29 installed on the air pipe 31 is from the air impurity removal box 5 to the inside of the air pipe 31.

[0051] An installation groove is formed in the lower side of the operation table 1. Two sub-gears 15 are rotatably installed in the installation groove. Both of the two sub-gears 15 are fixedly installed with driving bars 8. The driving bars 8 are in an S-shaped structure. Two driving openings are respectively formed on both sides of the driving bar 8. First-level driving rods 9 are respectively fixedly installed on the lower sides of the two first-level moving blocks 22. The two first-level driving rods 9 are respectively slidably installed in the two driving openings of one of the driving bars 8. Second-level driving rods 12 are respectively fixedly installed on the lower sides of the two second-level moving blocks 23. The two second-level driving rods 12 are respectively slidably installed in the two driving openings of the other driving bar 8.

[0052] With the above structure, the two sub-gears 15 have the same size, and driving bars 8 are installed on the lower sides of both of the two sub-gears 15. The driving bars 8 are in an S shape, and two arc-shaped driving openings are formed on the surface. The two driving openings on one driving bar 8 correspond to the two first-level driving rods 9, and the two driving openings on the other driving bar 8 correspond to the two second-level driving rods 12, respectively driving the two first-level driving rods 9 and the two second-level driving rods 12.

[0053] A support frame 7 is fixedly installed on the lower side of the operation table 1. A driving motor 11 is fixedly installed on the support frame 7. A main gear disk 10 is fixedly installed at the output end of the driving motor 11. The main gear disk 10 meshes with the two sub-gears 15. An infrared sensor 55 is fixedly installed on the upper side of the operation table 1. The infrared sensor 55 is electrically connected to the driving motor 11.

[0054] With the above structure, the main gear disk 10 is located between the two sub-gears 15. When the main gear disk 10 is driven by the driving motor 11 and rotates, it drives the two sub-gears 15 to rotate in the same direction, thereby driving the two driving bars 8 simultaneously. When the stainless steel heat-insulated cup moves to the area of the infrared sensor 55, the driving motor 11 will be started to rotate, so that the two cleaning frames 3 move away from each other, and the two grinding frames 4 move closer to each other and stop. When the stainless steel heat-insulated cup moves out of the area of the infrared sensor 55, the driving motor 11 rotates in reverse to reset it.

[0055] The ejection unit includes a mounting block 52 which is fixedly installed in the mounting hole. A sliding hole is formed on one side of the mounting block 52, and a trigger block 53 is slidably installed in the sliding hole. A fitting block 41 is fixedly installed on the upper side of the operating table 1. One side of the sliding column 44 is fixedly installed with a telescopic rod 54. One end of the telescopic rod 54 is fixedly installed with a connecting plate 50. One side of the connecting plate 50 is fixedly installed with a clamping block 49. A compression spring 51 is sleeved on the surface of the telescopic rod 54.

[0056] With the above structure, there is a certain space between the sliding column 44 and the sleeve 39 to provide movement space for the clamping block 49. When the sleeve 39 is in contact with the fitting block 41, the arc groove of the fitting block 41 is in contact with the surface of the sleeve 39, the trigger block 53 is squeezed, the clamping block 49 disengages from the sliding opening, the sliding column 44 is unlocked, and the return spring 42 drives the sliding column 44 to pop up upward to complete the ejection of the painted thermos cup.

[0057] In the processing step of S3, the painting assembly includes two paint guns 6, and the two paint guns 6 are fixedly installed on the upper side of the operating table 1.

[0058] With the above structure, the paint gun 6 is a prior art, and a liquid inlet is provided on its upper side. During use, it is necessary to externally connect paint liquid to it, and the surface of the stainless steel thermos cup is painted by opening and closing the electric control paint gun 6.

[0059] The working principle of the present invention is as follows: Before processing, first wipe and clean the polished area of the stainless steel thermos cup with clean water or a cleaning agent to ensure the surface is clean. After cleaning, invert the cup mouth of the stainless steel thermos cup on the sleeve 39 so that the cup mouth fits into the groove of the baffle 2. Then press the stainless steel thermos cup downward by hand, so that the rubber block 43 is stressed. The rubber block 43 drives the sliding column 44 to move downward, compresses the return spring 42, and at the same time drives the four secondary support rods 48 to move. The four secondary support rods 48 respectively drive the primary support rods 45 to move. Through the cooperation of the primary support rods 45 and the secondary support rods 48, the four anti-slip rubber pads 46 are driven to move away from each other and fit on the inner wall of the stainless steel thermos cup. When continuously pressing, the sliding column 44 drives the compression spring 51 to move downward, the compression spring 51 drives the connecting plate 50 to move downward, and the connecting plate 50 drives the clamping block 49 to move downward. When the clamping block 49 and the trigger block 53 are at the same horizontal plane, under the elastic force of the compression spring 51, the clamping block 49 is driven to insert into the sliding hole and squeeze the trigger block 53 out of the sliding hole. At the same time, the telescopic rod 54 drives the sliding column 44 to be fixed, completing the positioning of the anti-slip rubber pads 46 and fixing the stainless steel thermos cup.

[0060] After starting the moving motor 38, the moving motor 38 drives the moving lead screw 14 to rotate. The moving lead screw 14 drives the driving block 36 to move. The driving block 36 drives the sleeve 39 to move. The sleeve 39 drives the sliding column 44 to move. The sliding column 44 drives the stainless steel thermos cup to move horizontally through a plurality of anti-slip rubber pads 46. At the same time, under the action of the rotating rack 13 and the self-rotating gear 37, the stainless steel thermos cup rotates while moving horizontally. When the painted area of the stainless steel thermos cup fits on the surface of the water-absorbing sponge 18, the rotation of the thermos cup drives the water-absorbing sponge 18 to rotate, and the water-absorbing sponge 18 absorbs the water stains on the painted area. After the water absorption is completed, when the stainless steel thermos cup passes by the infrared sensor 55, the driving motor 11 is started. The driving motor 11 drives the main gear disk 10 to rotate. The main gear disk 10 drives the two sub-gear disks 15 to rotate. The two sub-gear disks 15 drive the two driving bars 8 to move. One of the driving bars 8 drives the two first-level driving rods 9 to move. The two first-level driving rods 9 respectively drive the two first-level moving blocks 22 to move. The two first-level moving blocks 22 drive the two cleaning frames 3 to move away from each other. At the same time, the other driving bar 8 drives the two second-level moving blocks 23 to move. The two second-level moving blocks 23 drive the two grinding frames 4 to move closer to each other. The two grinding frames 4 drive the sandpapers 26 to move closer to each other through the two rollers 28, so that the sandpapers 26 fit on the painted area of the stainless steel thermos cup.

[0061] During the movement, the two cleaning frames 3 move away from each other. The first-level moving rack 16 drives the water-absorbing sponge 18 to rotate. When the water-absorbing sponge 18 rotates, the scraper 20 drives to scrape water, scraping off the liquid adsorbed on the surface of the water-absorbing sponge 18 and collecting it into the collecting dish 21. At the same time, the grinding frame 4 drives the L-shaped rod 35 to move horizontally through the second-level moving gear 30. The L-shaped rod 35 drives the piston 33 to move horizontally in the air purification box 5, so that the air purification box 5 inhales the outside air through the one-way suction nozzle 34.

[0062] When the stainless steel thermos cup moves to the area between the two sandpapers 26, the sandpapers 26 drive the painted area of the stainless steel thermos cup to be polished to improve the adhesion of the paint layer. When the stainless steel thermos cup completely passes by the infrared sensor 55, the grinding is completed, and the driving motor 11 rotates in reverse, and the grinding frame 4 and the cleaning frame 3 return to their original positions. At this time, the grinding frame 4 drives the roller 28 to drive the second-level moving gear 30 to rotate through the one-way shaft, so that the lower roller 28 rotates, winding up the used sandpaper 26 and loading a new sandpaper 26 from the upper roller 28. The L-shaped rod 35 returns to its original position, driving the piston 33 to squeeze the air in the air purification box 5, and conveying it through the air pipe 31 into the hollow pipe 25, and finally blowing off the grinding and polishing powder and other impurities through the air nozzle 32.

[0063] Finally, the stainless steel vacuum cup moves between the paint spray guns 6, and the paint spray guns 6 are activated to spray paint, evenly spraying the paint area on the surface of the vacuum cup. When the sleeve 39 fits with the fitting block 41, the arc-shaped groove of the fitting block 41 fits with the surface of the sleeve 39, the trigger block 53 is squeezed, the clamping block 49 disengages from the sliding opening, and the sliding column 44 is unlocked. The return spring 42 drives the sliding column 44 to pop up upward to complete the ejection of the painted vacuum cup. At this time, the moving motor 38 is stopped, the stainless steel vacuum cup is removed by using a tool to clamp the cup mouth, and the moving motor 38 is started to reverse to reset the driving block 36, completing the painting operation of the stainless steel vacuum cup.
