Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paint painting, in particular to a paint painting mechanism. BACKGROUND

[0002] Paint, the traditional name in China is paint. So-called paint is coated on the surface of the protected or decorated object, and can form a firm and continuous film with the coated object. Usually, it is prepared by adding or not adding pigments, fillers, and corresponding additives to resin, oil or emulsion, and using organic solvent or water.

[0003] At present, when the ground of the traditional basement, basketball court and other areas is painted with epoxy resin, first of all, the staff uses a sander to polish the surface of the ground. After the polishing treatment is completed, the ground is cleaned to remove the dust. After removal, the staff evenly applies the primer of epoxy resin to the ground by scraper. After the primer of the ground is dried, the primer is polished by sander. After polishing, it is cleaned again. After cleaning, the finish is evenly brushed on the primer by using the brush roller. The epoxy resin is painted on the ground.

[0039] Embodiment one

[0040] In order to solve the technical problems in the background art, the following paint brushing mechanism is given:

[0041] Combining Figures 1-16 As shown in the drawings, the paint painting mechanism provided by the present application comprises a moving vehicle body 1, a partition plate 2 fixedly connected in the middle of the inner cavity of the moving vehicle body 1, a rotating assembly 3 installed on the top surface of the middle of the partition plate 2, a polishing and dust removing assembly 4 and a switching assembly 5 symmetrically installed on the rotating assembly 3, a scraper assembly 6 and a brush roller assembly 7 respectively installed on the inner cavity wall of the moving vehicle body 1 and located at the upper and lower ends of the switching assembly 5, the switching assembly 5 connected with the scraper assembly 6 or the brush roller assembly 7, a paint assembly 9 installed on the top surface of the moving vehicle body 1, and the output end of the paint assembly 9 connected with the switching assembly 5; the rotating assembly 3 comprises a rotating motor 31 and a gear disc 32, the rotating motor 31 fixedly connected to the bottom surface of the partition plate 2, the output shaft end of the rotating motor 31 penetrating through the partition plate 2 and the extended part fixedly connected with a transmission gear 33, the gear disc 32 rotatably connected with the partition plate 2 through a rotary disc bearing in the middle of the top surface of the partition plate 2, the transmission gear 33 meshingly connected with the gear disc 32, and the switching assembly 5 and the polishing and dust removing assembly 4 symmetrically installed on the gear disc 32; the switching assembly 5 comprises a first lifting part 51, the first lifting part 51 fixedly connected with a disc 52 on the bottom surface, a reciprocating part 53 installed on the top surface of the disc 52 in the middle, a fan-shaped groove 54 provided on the bottom surface of the disc 52, a swing locking part 55 installed in the disc 52 and located at the center of the fan-shaped groove 54, an inclined groove 56 provided in the disc 52, rectangular grooves 57 respectively provided on the top surface of the disc 52 and located at the two sides of the reciprocating part 53, a receiving groove 58 provided in the middle of the bottom surface of the disc 52 and communicated with the inner cavities of the rectangular grooves 57, and an arc-shaped rod 59 fixedly connected with one side of the first lifting part 51; the reciprocating part 53 comprises a reciprocating motor 531 and a reciprocating rod 532, the reciprocating motor 531 fixedly connected with the disc 52 in the middle of the top surface, a reciprocating disc 533 fixedly connected with the output shaft end of the reciprocating motor 531, a positioning rod 534 fixedly connected with the top surface of the reciprocating disc 533, reciprocating grooves 535 and square holes 536 respectively provided on the top surface of the reciprocating rod 532, and the positioning rod 534 sliding in the reciprocating grooves 535 while driving the reciprocating rod 532 to reciprocate.

[0042] The above structure can achieve the following effects:

[0043] 1. The rotating assembly 3 can switch the positions of the polishing and dust removing assembly 4 and the switching assembly 5, which is convenient for polishing, scraping or painting in the later stage;

[0044] 2. The second lifting part 41 in the polishing and dust removing assembly 4 is used to adjust the fixing of the polishing disc 45, then the polishing motor 42 and the polishing disc 45 are matched with each other to polish the surface of the ground, when polishing, the dust collecting machine 43 and the dust blocking disc 44 are matched with each other to collect the dust, at the same time, the arc-shaped brush 47 is used to clean the dust and block the dust under the arc-shaped suction cavity 46, which is convenient for absorbing the dust in the later stage;

[0045] 3. Through the cooperation of switching component 5, scraper component 6 and brush roller component 7, when scraper component 6 is needed, it can be installed on switching component 5. With the cooperation of reciprocating motor 531 and reciprocating rod 532 in switching component 5, scraper 621 is driven to swing. When brush roller component 7 is needed, scraper 621 can be disassembled and U-shaped roller frame 721 can be installed on switching component 5. With the cooperation of reciprocating motor 531 and reciprocating rod 532 in switching component 5, U-shaped roller frame 721 and brush roller 723 can be driven to swing back and forth, which facilitates subsequent brushing.

[0046] In order to enable the reciprocating component 53 to drive the scraper 621 or the U-shaped roller frame 721 to reciprocate, this embodiment provides the following technical solution:

[0047] In this embodiment, the reciprocating component 53 further includes a first damping rod 537 and a convex rod 538. The first damping rod 537 is symmetrically and fixedly connected to the top surface of the disk 52. A lifting frame 539 is fixedly connected to the top surface of the first damping rod 537. A convex rod 538 is installed on the top surface of the lifting frame 539, above the reciprocating rod 532. The middle part of the convex rod 538 is engaged with the surface of the reciprocating rod 532, and the two ends of the convex rod 538 slide back and forth within the rectangular groove 57. A dovetail block 5310 is fixedly connected to the middle of the bottom surface of the convex rod 538. The storage groove 58 is used to store the lower part of the convex rod 538 and the dovetail block 5310. Spring beads 5311 are installed on both sides of the inside of the dovetail block 5310. A rotating block 5312 is rotatably connected inside the lifting frame 539. A first protrusion 5313 is provided in the middle of the rotating block 5312. A locking rod 5314 for resetting and locking is fixedly connected to one side of the lifting frame 539 for the swing locking component 55.

[0048] When in use, the switching component 5 exists in two states: first, it drives the scraper to swing; second, it drives the U-shaped roller frame to reciprocate. Simultaneously, the switching component 5 has four states during installation and disassembly:

[0049] When the scraper 621 is installed, the lifting frame 539 is lifted by the first square rod 623, and then the convex rod 538 is lifted by the lifting frame 539, so that the convex rod 538 is separated from the reciprocating rod 532, and at the same time, the lower part of the convex rod 538 is accommodated in the slot 58 of the dovetail block 5310. This facilitates the installation of the scraper 621 later. When the convex rod 538 is separated, the second square rod 624 at the upper part of the first square rod 623 will be connected with the square hole 536 on the reciprocating rod 532, and at the same time, the first square rod 623 is locked by the swing locking part 55. At this time, the reciprocating motor 531 drives the reciprocating rod 532 to swing around the second square rod 624 by cooperating with the positioning rod 534, so that the scraper 621 can swing back and forth, which facilitates the scraping of the primer later.

[0050] When the scraper 621 is removed, the locking structure in the swing locking part 55 is opened by the inclined rod 64 cooperating with the inclined slot 56, so that the locking piece 555 does not lock the first square rod 623. Under the action of gravity, the scraper 621 can fall down, and the lifting frame 539 will be reset under the action of the first damping rod 537. After resetting, the convex rod 538 will move downward and be clamped on the surface of the reciprocating rod 532, and at the same time, the lower part of the convex rod 538 and the dovetail block 5310 will move out of the slot 58;

[0051] The installation of the U-shaped roller frame 721 is reset under the action of the third damping rod 71. After resetting, the dovetail block 5310 slides into the dovetail groove 722, and the U-shaped roller frame 721 is fixed by the spring bead 5311. When the U-shaped roller frame 721 contacts the dovetail block 5310, the locking block 725 contacts the moving block 774, so that the moving block 774 moves, so that the hanging hook 779 enters the second groove 778 from the arc-shaped groove 777, and returns to the first groove 776, so that the moving block 774 is not locked, and at the same time, the moving block 774 moves the clamping jaw 775 to the outside of the connecting box 771 and opens, so that the locking block 725 is not locked, which facilitates the use of the U-shaped roller frame 721 later. When used, first, the reciprocating motor 531 drives the reciprocating rod 532 to reciprocate, and after reciprocating, the convex rod 538, the dovetail block 5310, the U-shaped roller frame 721 and the brush roller 723 reciprocate, which facilitates the uniform application of the topcoat on the primer later;

[0052] When the U-shaped roller frame 721 is removed, the locking block 725 contacts the moving block 774 again, so that the moving block 774 moves, so that the hanging hook 779 enters the arc-shaped groove 777 from the first groove 776, so that the clamping jaw 775 is accommodated in the connecting box 771, so as to fix the U-shaped roller frame 721, and at the same time, the U-shaped roller frame 721 is disassembled from the switching assembly 5.

[0053] In order to make the swing locking part 55 realize the locking of the first square rod 623 and the scraper 621, the embodiment will give the following technical solutions:

[0054] In the embodiment, the swing locking part 55 comprises a T-shaped swing circle 551 and a U-shaped handle 552, the T-shaped swing circle 551 is rotatably connected inside the disc 52, the top surface of the T-shaped swing circle 551 is fixedly connected with a locking plate 553, the locking plate 553 is slidably connected with a locking rod 554, one end of the locking rod 554 is fixedly connected with a locking piece 555, the locking piece 555 is fixedly connected with a locking spring 556 on one side and in the region between the locking plates 553, the U-shaped handle 552 is installed on one side of the locking plate 553, the locking rod 554 is rotatably connected with the U-shaped handle 552 through a pin shaft, one end of the locking top rod 5314 is in contact with one end of the U-shaped handle 552, and the second convex groove 557 is arranged in the middle of the T-shaped swing circle 551.

[0055] Through the rotation of the U-shaped handle 552, the movement of the T-shaped swing circle 551 is driven, when the T-shaped swing circle 551 moves, the locking piece 555 moves, when the locking piece 555 moves, the locking spring 556 contracts or resets, when the locking spring 556 contracts, the locking piece 555 part locks the first square rod 623, and vice versa.

[0056] Embodiment two

[0057] As Figures 1-16 shown, on the basis of the above embodiment, the embodiment further gives the following contents:

[0058] In order to make the scraper assembly 6 convenient for the switching assembly 5 to take or put it down in the later stage, the embodiment gives the following technical solutions:

[0059] The scraper assembly 6 comprises a bottom plate 61 and a scraper part 62, the bottom plate 61 is fixedly connected to the lower part of the inner cavity wall of the moving vehicle body 1, the top surface of the bottom plate 61 is fixedly connected with a second damping rod 63 and an inclined rod 64 respectively, the top surface of the second damping rod 63 is fixedly connected with a storage plate 65, the top surface of the storage plate 65 is fixedly connected with a limiting nail 66, the scraper part 62 is placed on the top surface of the storage plate 65 between the two groups of limiting nails 66, and the inclined groove 56 is slidably connected with the inclined rod 64 for unlocking the locking structure of the swing locking part 55;

[0060] The scraper component 62 includes a scraper 621. A cylindrical rod 622 and a first square rod 623 are fixedly connected to the top surface of the scraper 621. A second square rod 624 is fixedly connected to the top surface of the first square rod 623. The diameter of the second square rod 624 is smaller than that of the first square rod 623. A locking hole 625 is fixedly connected to one side of the first square rod 623. One end of the locking piece 555 is inserted into the inner cavity of the locking hole 625. The first square rod 623 slides in the second protrusion 557, and the top surface of the first square rod 623 is in contact with the bottom surface of the rotating block 5312. The outer surface of the second square rod 624 slides in the first protrusion 5313 and the square hole 536, respectively.

[0061] The base plate 61 and the limiting pin 66 work together to store the scraper 621. The inclined rod 64 works together with the inclined groove 56 to change the swing locking component 55 from the original locked state to the unlocked state, so that the locking plate 555 no longer locks the first square rod 623, making it convenient to remove the scraper 621 from the switching component 5 later.

[0062] By using the trapezoidal design of the scraper 621, excess primer can be scraped towards the narrower end during scraping, allowing the primer to be evenly applied to the ground while preventing primer buildup.

[0078] The working principle and use process of the application are as follows:

[0079] In use:

[0080] Preparation work:

[0081] Firstly, the primer is put into the first paint tank 91, and then the topcoat is put into the second paint tank 92, and after being put in, the next step can be started.

[0082] When polishing the ground:

[0083] Firstly, the second lifting component 41 is started, and the polishing motor 42, the polishing disc 45 and the dustproof disc 44 are lifted as a whole through the cooperation of the pneumatic rod of the second lifting component and the lifting rod, and when the bottom surface of the polishing disc 45 contacts the ground, the movement is stopped, and the polishing motor 42 and the dust collector 43 are started, and when the polishing motor 42 works, the polishing disc 45 rotates, and the surface layer of the ground is polished into powder, at this time, the staff can move the vehicle body 1 to move the whole vehicle, and the polishing is realized while moving; when polishing, the dust collector 43 works, and the dust is sucked into the dust collector 43 through the cooperation of the hose 48 and the arc-shaped suction cavity 46, and the dust that is not easy to be sucked is gathered in the lower part of the arc-shaped suction cavity 46 under the block of the arc-shaped brush 47, which is convenient for collection later.

[0084] The scraper is installed:

[0085] When polishing and cleaning, the first lifting component 51 drives the disc 52, the reciprocating component 53 and the swing locking component 55 to move downward as a whole, and when moving downward, the first square rod 623 and the second square rod 624 pass through the second convex groove 557 respectively, and after passing through, the second square rod 624 passes through the first convex groove 5313, and the first square rod 623 does not pass through the first convex groove 5313, and the top surface of the first square rod 623 contacts the bottom surface of the rotating block 5312, and when the first square rod 623 rises, the rotating block 5312 and the lifting frame 539 move upward, and when the lifting frame 539 moves upward, the first damping rod 537 is stretched, and the convex rod 538 moves upward and is separated from the reciprocating rod 532, and when the first square rod 623 and the second square rod 624 continue to rise, the upper end of the second square rod 624 is inserted into the square hole 536, and the locking piece 555 in the swing locking component 55 is inserted into the locking hole 625 under the action of the locking spring 556, and when the locking spring 556 is inserted, the first square rod 623 is fixed on the swing locking component 55, and when the first square rod 623 is locked, the cylindrical rod 622 is inserted into the fan-shaped groove 54, which is convenient for reciprocating movement later, and when the scraper 621 is fixed on the reciprocating component 53, the first lifting component 51 drives the disc 52, the reciprocating component 53, the scraper 621 and the swing locking component 55 to move upward as a whole.

[0086] The ground is paved with a layer of epoxy resin primer:

[0087] First, start the second lifting component 41, when the second lifting component 41 work, will drive the polishing motor 42, dust disc 44, polishing disc 45 as a whole to move up, when the whole moves to a certain height, at this time start the rotating motor 31, rotating motor 31 work, will drive the transmission gear 33 to rotate, when the transmission gear 33 rotates, will drive the gear plate 32 to rotate, when the gear plate 32 rotates, will make the polishing dust removal assembly 4 and switching assembly 5 switch positions with each other;

[0088] After the position is exchanged, at this time, start the first lifting component 51, the first lifting component 51 works, through the cooperation of pneumatic rod and lifting rod, drives the disc 52, reciprocating component 53, swing locking component 55 and scraper 621 as a whole to move down, when the bottom surface of the scraper 621 is close to contact with the ground, stop the work of the first lifting component 51, at the same time, start the reciprocating motor 531 and the liquid pump 97, and at this time the three-way valve 94 is in communication with the first feeding pipe 93 and the collection pipe 96, after communication, the liquid pump 97 works, starts to pump the primer in the first material box 91 into the collection pipe 96 through the first feeding pipe 93, finally, discharges through the liquid discharge pipe 98, and the discharged primer falls on the ground, when the reciprocating motor 531 works, drives the reciprocating disc 533 to rotate, when the reciprocating disc 533 rotates, drives the positioning rod 534 to move in a circle, when the positioning rod 534 moves in a circle, slides in the reciprocating groove 535 at the same time, also drives the reciprocating rod 532 to reciprocate around the second square rod 624 as the center, when the second square rod 624 reciprocates, drives the first square rod 624 to reciprocate, when the first square rod 624 swings, drives the scraper 621 to reciprocate, when the scraper 621 reciprocates, can scrape the discharged primer flat through the scraper 621, because the scraper 621 is set to trapezoidal shape, so that when scraping, the excess material can be scraped to the lower part, to prevent the accumulation of excess primer.

[0089] After brushing the primer, start polishing the epoxy primer:

[0090] When polishing the primer, first, the disc 52, reciprocating part 53, swing locking part 55 and scraper 621 are moved upward as a whole by the first lifting part 51, when the scraper 621 is lifted to a certain height, the first lifting part 51 stops working, and the rotating motor 31 is started, when the rotating motor 31 works, the toothed disc 32 will be rotated by the transmission gear 33, when the toothed disc 32 rotates, the switching assembly 5 and the polishing dust removal assembly 4 will be switched again, after switching, the second lifting part 41 is started, which will move the polishing motor 42, dust blocking disc 44, polishing disc 45 and arc-shaped brush 47 downward as a whole, when the polishing disc 45 contacts the primer, the surface of the primer is polished, the polishing steps are as follows:

[0091] When polishing, the scraper is removed and replaced with a brush roller:

[0092] Firstly, the first lifting component 51 is started, which will drive the disc 52, the reciprocating component 53, the swing locking component 55 and the scraper 621 to move downward as a whole. When the scraper 621 moves downward, the bottom surface of the scraper 621 is located on the upper portion of the storage plate 65 and is limited and fixed by the limiting nails 66. When the scraper 621 is located on the upper portion of the storage plate 65, the first lifting component 51 will continue to drive the scraper 621 to move downward. When the scraper 621 moves downward, the storage plate 65 will move downward and the second damping rod 63 will be retracted. When the storage plate 65 moves downward, the inclined rod 64 will slide into the inclined slot 56 and pass through the inclined slot 56, so that one end of the inclined rod 64 abuts against the U-shaped handle 552. Then, the U-shaped handle 552 is rotated, so that the locking rod 554 moves towards the U-shaped handle 552, thereby making the locking piece 555 disengage from the locking hole 625. After disengagement, the U-shaped handle 552 is rotated by 90 degrees and is rotated from the original vertical state to the horizontal state. When the locking piece 555 is limited by the first square rod 623, the first lifting component 51 will stop moving downward and start moving upward. When the first lifting component 51 drives the disc 52, the reciprocating component 53 and the swing locking component 55 to move upward as a whole, the inclined rod 64 will first exit from the inclined slot 56, and the storage plate 65 will be reset under the action of the second damping rod 63. After resetting, the first lifting component 51 will continue to rise. At this time, the scraper 621 will stay on the storage plate 65 under the action of gravity. When the scraper 621 does not rise, the first square rod 623 will move downward under the cooperation of the lifting frame 539 and the first damping rod 537. When the lifting frame 539 moves downward, the locking top rod 5314 will move downward. When the locking top rod 5314 moves downward, it will contact the upper portion of the U-shaped handle 552 and drive the U-shaped handle 552 to rotate, so that the U-shaped handle 552 is reset. At this time, the locking piece 555 starts to reset. After resetting, it will be convenient for the next time to lock the first square rod 623. At the same time of resetting, the convex rod 538 will move downward under the action of gravity. When the convex rod 538 moves downward, it will be clamped on the surface of the reciprocating rod 532. When the convex rod 538 moves downward, the lower portion of the convex rod 538 and the dovetail block 5310 will be removed from the storage slot 58. When the U-shaped handle 552 and the convex rod 538 are reset, when the first square rod 623 moves downward, the second square rod 624 will move downward, so that the second square rod 624 will disengage from the square hole 536.

[0093] After disengaging, the arc-shaped rod 59 on the side of the first lifting component 51 will be in contact with one end of the retreat rod 73. After contact, the retreat rod 73 is pressed, causing it to move to one side and press the third damping rod 71. When the retreat rod 73 moves, it will drive the sector-shaped rod 74, the roller brush component 72, the fourth damping rod 75, the descending rod 76, and the connecting component 77 as a whole to move to one side, thereby facilitating the passage of the disc 52 from the side of the roller brush component 72. When the disc 52 passes through the roller brush component 72, the retreat rod 73 disengages from the arc-shaped rod 59. When the retreat rod 73 disengages, it will be reset under the action of the fourth damping rod 75. When the retreat rod 73 is reset, the sector-shaped rod 74 will be in contact with the arc-shaped rod 59, facilitating the retreat rod 73 to be in contact with the arc-shaped rod 59 in the later stage. When the retreat rod 73 is reset, the roller brush component 72, the fourth damping rod 75, the descending rod 76, and the connecting component 77 as a whole will be reset. When they are reset, the U-shaped roller frame 721 will drive the brush roller 723 to move towards the dovetail block 5310, causing the dovetail block 5310 to slide into the dovetail groove 722. When the dovetail block 5310 slides in, the locking block 725 on the side of the U-shaped roller frame 721 will start to hit the moving block 774. The moving block 774 moves, pressing the fifth damping rod 773. At this time, the suspension hook 779 will also move from the arc-shaped groove 777 to the second section of the groove 778. This will cause the clamping jaw 775 to not clamp the locking block 725. At this time, the first lifting component 51 drives the disc 52 as a whole to move downward. When the disc 52 moves downward, it will drive the U-shaped roller frame 721, the connecting component 77, and the descending rod 76 to descend and stretch the fourth damping rod 75. Because the U-shaped roller frame 721 does not disengage due to the cooperation of the supporting plate 724 and the supporting rod 772 at this time, when the retreat rod 73 is pressed and retreated by the arc-shaped rod 59, the supporting rod 772 and the supporting plate 724 will separate from each other. After separation, the first lifting component 51 will drive the U-shaped roller frame 721 to move to the appropriate position, and then stop the work of the first lifting component 51.
