Description

Technical Field

[0001] This invention relates to a putty spraying equipment for building materials, used for applying putty to decorative panels in the construction industry. Background Technology

[0002] Decorative panels are frequently used during house construction. These panels often have wood pores and defects. Before painting, putty needs to be sprayed onto the surface of the panels to make the surface smooth. Spraying putty onto the surface of the panels can also prevent the paint from sinking or losing its gloss.

[0003] Chinese patent application number CN202210407627.3 discloses a putty spraying device for building construction boards. The board is placed on the feeding mechanism, which moves the board backward to a suitable position. The feeding mechanism drives the feeding mechanism to operate, which discharges putty into the spray nozzle. The spray nozzle then sprays the putty onto the board. In this way, there is no need for a person to manually spray the putty onto the board, which is more labor-saving.

[0004] However, the aforementioned patents also have the following drawbacks:

[0005] Firstly, the sizes of boards vary widely, and the aforementioned patent can only apply putty to boards of fixed sizes.

[0006] Secondly, during the putty spraying process, boards with different surface qualities require different thicknesses of putty to be sprayed, and the aforementioned patent cannot adjust the thickness of the putty spraying.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] like Figure 1-20 As shown, the present invention has the following specific embodiments. Example 1

[0049] A board putty spraying device includes a board A1, a base 1, a drive device, a spraying device, a scraper 4, and a drying device. A sliding groove 11 is formed in the middle of the base 1, and a double-ended screw 12 is rotatably connected to the middle of the sliding groove 11. An adjustable-pitch motor 13 for driving the double-ended screw 12 is fixedly connected to the front side of the base 1. Sliding rods 14 are fixedly connected to the sliding grooves 11 on both sides of the double-ended screw 12. Mounting seats 15 are symmetrically slidably connected to the base 1, and sliding plates 16 are fixedly connected to the bottom of the mounting seats 15. The sliding plates 16 are slidably connected to the sliding rods 14, and the two sliding plates 16 are respectively slidably connected to the double-ended screw 12. The two first threaded grooves mesh in opposite directions. A conveying groove 17 is provided on the upper part of the inner wall of the mounting base 15. A conveying wheel 18 is horizontally and evenly rotatably connected to the lower inner side of the mounting base 15. A driving device is used to drive the conveying wheel 18 to rotate. A spraying device, a scraper 4, and a drying device are arranged sequentially from left to right along the upper edge of the mounting base 15. The spraying device is used to spray putty onto the board A1 and can adjust the spraying width according to the distance of the mounting base 15. There are two scrapers 4, which are fixed on the front and rear mounting bases 15 respectively. The scrapers 4 are used to scrape off excess putty. The drying device is used to dry the sprayed putty.

[0050] In this embodiment, as Figure 1-3 As shown, the adjustable pitch motor 13 drives the double-headed screw 12 to rotate. Since the mounting base 15 is slidably connected to the slide rod 14 through the sliding plate 16, and the front and rear sliding plates 16 respectively mesh with the two first thread grooves with opposite directions of rotation on the double-headed screw 12, the rotation of the double-headed screw 12 can make the two mounting bases 15 move closer or further away from each other, so that the distance between the two mounting bases 15 is adapted to the width of the plate A1 to be sprayed.

[0051] Insert board A1 into the conveying trough 17 from the left side, with the bottom of board A1 in contact with the conveying wheel 18. Looking from front to back, the drive device drives the conveying wheel 18 to rotate clockwise, so that board A1 is conveyed from left to right. During this process, the spraying device is used to spray putty onto board A1, and the spraying width can be adjusted according to the distance of the mounting seat 15. The two scraper seats 4 can scrape off the excess putty. The drying device is used to dry the sprayed putty. Thus, putty can be sprayed onto board A1. Example 2

[0052] The drive unit includes a lifting box 21, a drive shaft 22, and a drive motor 23. A lifting groove 24 is formed in the lower part of the inner wall of the mounting base 15. A drive cavity 25 is formed below the lifting groove 24. A drive shaft 26 is rotatably connected within the lifting groove 24 corresponding to the position of the conveyor wheel 18. A first worm gear 27 is fixedly connected to the bottom of the drive shaft 26. The lifting box 21 is slidably connected in the lifting groove 24 and its height is adjusted by an adjusting device. A sleeve 28 is rotatably connected to the top plate of the lifting box 21, and the outer ring of the sleeve 28 is fixedly connected to... The first driving bevel gear 29 and the drive shaft 26 are slidably connected inside the sleeve 28. The bottom plate of the lifting box 21 has a clearance hole 210 for the drive shaft 26 to pass through. The inner wall of the sleeve 28 has evenly spaced first linkage grooves 211. A first linkage block 212, adapted to the first linkage groove 211, is fixedly connected to the drive shaft 26. The conveyor wheel 18 is rotatably connected to the side plate of the lifting box 21 via a mounting shaft 213. A first driven bevel gear 29, meshing with the first driving bevel gear 29, is fixedly connected to the head of the mounting shaft 213. 14. A drive housing 215 is fixedly connected to the right side of the mounting base 15. A drive shaft 22 is rotatably connected to the drive cavity 25. A first worm 216 meshing with a first worm gear 27 is fixedly connected to the drive shaft 22. The right end of the drive shaft 22 extends into the drive housing 215 and is fixedly connected to a second driven bevel gear 217. A spindle 218 and a sleeve 219 are rotatably connected to the side plates of the two drive housings 215 that are close to each other. One end of the spindle 218 and the sleeve 219 extending into the drive housing 215 is fixedly connected to a second driven bevel gear 217. The second driving bevel gear 220 meshes with gear 217. The spindle 218 is slidably connected in the sleeve 219. The inner wall of the sleeve 219 is evenly provided with a second linkage groove 221. A second linkage block 222 that matches the second linkage groove 221 is fixedly connected to the spindle 218. The drive motor 23 is fixedly connected to the outer wall of the front drive box 215. The output shaft of the drive motor 23 is rotatably connected to the front plate of the drive box 215, and the output shaft of the drive motor 23 is concentrically fixed with the second driving bevel gear 220 on the front side.

[0053] Furthermore, the adjustment device includes a shaft 61, an adjustment seat 62, and a rocker arm 63; the shaft 61 is rotatably connected to the lower part of the inner wall of the mounting base 15, a knob 64 is fixedly connected to the left end of the shaft 61, and a second threaded groove 65 is evenly opened laterally on the shaft 61. The adjustment seat 62 engages with the second threaded groove 65 and fits against the mounting base 15. A pin 66 corresponding to the adjustment seat 62 is fixedly connected to the outer wall of the lifting box 21. The two ends of the rocker arm 63 are respectively hinged to the pin 66 and the adjustment seat 62.

[0054] Furthermore, the left side of the mounting base 15 is provided with a scale line 67, and the left side plate of the lifting box 21 is fixed with a scale pointer 68.

[0055] In this embodiment, as Figure 9 and 10 As shown, the shaft 22 can be rotated by the knob 64. Because the adjusting seat 62 is in contact with the mounting base 15 and is guided, and the adjusting seat 62 engages with the second threaded groove 65, the rotation of the shaft 61 can move the adjusting seat 62. The adjusting seat 62 adjusts the height of the lifting box 21 via the swing arm 63, thereby adjusting the height of the conveyor wheel 18. Figure 2 As shown, the height of the lifting box 21 can be determined by the scale pointer 68. After the height of the conveyor wheel 18 is adjusted, the readings of the two scale pointers 68 on the scale line 67 should be consistent to ensure that the conveyor wheels 18 on the front and rear sides are at the same height.

[0056] The putty slurry is sprayed onto board A1 using a spraying device. Excess putty is scraped off as it passes the scraper seat 4. Figure 4 As shown in the figure, A2 is the thickness of the remaining putty on the board A1 after the scraper 4 is removed. When the height of the conveyor wheel 18 is adjusted, the bottom of the board A1 contacts the top of the conveyor wheel 18. The distance between the upper surface of the board A1 and the top surface of the mounting base 15 is the thickness of the remaining putty after the scraper 4 is removed. That is, the thickness of the remaining putty can be adjusted by adjusting the height of the conveyor wheel 18.

[0057] like Figure 4-5 As shown in 7-8, when the height of the lifting box 21 is adjusted to complete the adjustment of the height of the conveyor wheel 18, under the action of the first linkage block 212 and the first linkage groove 211, the transmission shaft 26 can always drive the first active bevel gear 29 to rotate, thereby causing the conveyor wheel 18 to rotate to complete the conveying of the plate A1.

[0058] like Figure 6 As shown, when the distance of the mounting base 15 is adjusted, the two drive boxes 215 move with the mounting base 15, while the spindle 218 and the sleeve 219 move with the front and rear drive boxes 215 respectively. However, under the action of the second linkage groove 221 and the second linkage block 222, the spindle 218 and the sleeve 219 always rotate synchronously.

[0059] like Figure 6 As shown, when the drive motor 23 rotates, it drives the front second driving bevel gear 220 and the sleeve 219 to rotate. The rear second driving bevel gear 220 and the spindle 218 rotate with the sleeve 219, so that the two second driving bevel gears 220 rotate synchronously, and the second driven bevel gear 217 meshing with it rotates, thereby driving the shaft 22 and the first worm 216 to rotate, and the first worm wheel 27 meshing with it to rotate, as shown. Figure 4-5 ,as well as Figure 15 As shown, the drive shaft 26 rotates with the first worm gear 27, the sleeve 28 and the first driving bevel gear 29 rotate with the drive shaft 26, and the first driven bevel gear 214 meshing with the first driving bevel gear 29 rotates, thereby rotating the mounting shaft 213 and the conveyor wheel 18. When the conveyor wheel 18 rotates, it conveys the plate A1.

[0060] like Figure 6 As shown, the two drive shafts 22 rotate in opposite directions, thus the first worm gears 216 on the front and rear sides rotate in opposite directions, as... Figure 4 As shown, when the spiral lines of the first worm gear 216 on both the front and rear sides are the same, the rotation of the first worm wheel 27 meshing with it is opposite. Therefore, the rotation of the transmission shaft 26 on both the front and rear sides is opposite. Since the first driven bevel gear 214 on both the front and rear sides mesh with the left and right sides of the first driving bevel gear 29 respectively, when the rotation of the transmission shaft 26 and the first driving bevel gear 29 on both the front and rear sides is opposite, the rotation of the first driven bevel gear 214 on both the front and rear sides is the same. That is, the rotation of the conveying wheel 18 on both the front and rear sides is the same. The rotation of the drive motor 23 is set so that when viewed from the front to the back, the conveying wheel 18 rotates clockwise, thereby conveying the plate A1 from left to right. Example 3

[0061] The drive cavity 25 is connected to the upper surface of the chipper seat 4 through the circular groove 41. The first rotating shaft 43 is rotatably connected to the circular groove 41 through the bearing 42. The bottom of the first rotating shaft 43 is fixedly connected to the second worm gear 44. The second worm 45 meshing with the second worm gear 44 is fixedly connected to the drive shaft 22. The top of the first rotating shaft 43 is fixedly connected to the third driving bevel gear 46. The transmission box 47 is fixedly connected to the chipper seat 4 at the position corresponding to the circular groove 41. The second rotating shaft 48 is rotatably connected to the chipper seat 4. The head of the second rotating shaft 48 extends into the transmission box 47 and is fixedly connected to the third driven bevel gear 49. The third driven bevel gear 49 meshes with the third driving bevel gear 46. A groove 410 is opened at the bottom of the chipper seat 4. The grinding wheel 412 is rotatably connected to the groove 410 through the third rotating shaft 411. The top of the third rotating shaft 411 is fixedly connected to the third worm gear 413. The third worm 414 meshing with the third worm gear 413 is fixedly connected to the second rotating shaft 48.

[0062] Furthermore, a set of grinding wheels 412 is provided on each of the left and right sides of the second rotating shaft 48, and the two sets of grinding wheels 412 are arranged alternately, with overlapping areas between two longitudinally adjacent grinding wheels 412.

[0063] In this embodiment, as Figure 11-15 As shown, when the drive shaft 22 rotates, it also drives the second worm 45 to rotate, and the second worm wheel 44 meshing with it to rotate, thereby the first rotating shaft 43 and the third driving bevel gear 46 to rotate, and the third driven bevel gear 49 meshing with it to rotate, thereby the second rotating shaft 48 and the third worm 414 to rotate, and the third worm wheel 413 meshing with it to rotate, and then the third rotating shaft 411 and the grinding wheel 412 to rotate.

[0064] After the sprayed putty is smoothed by scraping it with the scraper 4, the sprayed putty is polished smooth by rotating the grinding base.

[0065] like Figure 14 As shown, two longitudinally adjacent grinding wheels 412 have an overlapping area, which is region C in the figure, ensuring that the grinding wheel 412 can fully polish the putty smooth. Example 4

The second transmission bevel gear 317 meshes with a power bevel gear 310. The top of the mounting base 15 is fixedly connected to a support 318. Two first outer cylinders 34 are slidably connected to the outside of the corresponding first inner cylinder 33, and the first outer cylinders 34 are fixed inside the support 318. The outside of the support 318 is hinged to a positioning plate 319. The two positioning plates 319 are connected at their close ends through a flexible plate 320. The spray pipe 35 is fixed to the outside of the two positioning plates 319 and the flexible plate 320 through an ear plate 321. The two ends of the spray pipe 35 are respectively connected to the head of the corresponding first outer cylinder 34. Spray nozzles 322 are evenly arranged at the bottom of the spray pipe 35.

[0067] In this embodiment, as Figure 16 As shown, when the distance of the mounting base 15 is adjusted, the angle between the positioning plate 319 and the support 318 changes, so that putty can be sprayed on plates A1 of different widths.

[0068] like Figure 17 As shown, when the distance of the mounting base 15 is adjusted, the sliding of the first inner cylinder 33 within the second inner cylinder can also accommodate the movement of the mounting base 15.

[0069] like Figure 17-18 As shown, the feeding motor 32 drives the power bevel gear 310 to rotate, and the first transmission bevel gear 312 and the second transmission bevel gear 317 meshing with it rotate.

[0070] When the first transmission bevel gear 312 rotates, the first conveying shaft 311 and the first conveying blade 313 rotate. The spiral direction of the first conveying blade 313 is set so that when it rotates, it conveys the putty slurry from the feed cylinder 38 from top to bottom and enters the first inner cylinder 33 through the feed pipe 314.

[0071] When the second transmission bevel gear 317 rotates, the second conveying shaft 315 and the second conveying blade 316 rotate. The second conveying blades 316 on the front and rear sides rotate in opposite directions. When the spiral directions of the two are the same, the putty slurry can be conveyed in different directions. The spiral directions of the two are set so that when the two rotate, the putty slurry is conveyed in a direction away from the hanging box 39.

[0072] The putty slurry enters the second inner cylinder through the first inner cylinder 33 and is sprayed onto the board A1 through the spray pipe 35 and the nozzle 322. Example 5

[0073] The drying device includes a second outer cylinder 51, a heating box 52, and a second inner cylinder 53; a support plate 54 is fixedly connected to the outer wall of the mounting base 15, the second outer cylinder 51 is fixedly connected to the support plate 54, the heating box 52 is fixedly connected to the right front of the base 1, a heating grid 55 is fixedly connected inside the heating box 52, an exhaust fan 56 is fixedly connected inside the front side plate of the heating box 52, the rear side plate of the heating box 52 is connected to the front second outer cylinder 51 through a hot air pipe 57, an air groove 58 is opened at the bottom of the second inner cylinder 53, the two ends of the second inner cylinder 53 are movably connected to the second outer cylinder 51, and the second inner cylinder 53 is fixedly connected to the fixed base 36 through a second support rod 59.

[0074] In this embodiment, as Figures 19-20 As shown, when the position of the mounting base 15 is adjusted, the second inner cylinder 53 is fixed and remains stationary by the second support rod 59, and the second outer cylinder 51 moves along the second inner cylinder 53 to adapt to the movement of the mounting base 15. When the second outer cylinder 51 moves, the opening width of the air duct 58 can change to adapt to the width of the plate A1.

[0075] The exhaust fan 56 draws in air and heats it through the heating grid 55. The hot air enters the second outer cylinder 51 through the hot air pipe 57 and is sprayed out from the air duct 58, thereby drying the sprayed putty and properly drying the surface of the putty to prevent the coating from being damaged by the free flow of the putty after the board A1 is unloaded.

[0076] It is important to note that the airflow of the exhaust fan 56 should not be too strong to avoid damaging the putty after spraying.
