Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Embodiment 1

[0028] Please refer to Figure 1-7 , the present utility model provides a technical solution: an automatic coating machine, including: a coating machine body 1, a conveying device 2 is arranged on the lower side of the coating machine body 1, and a spray pipe 3 is arranged on the coating machine body 1,

[0029] It further includes a cleaning component 4, the cleaning component 4 is arranged on the spray pipe 3, and the cleaning component 4 is used to clean the residual coating raw materials at the lower spray port of the spray pipe 3 to prevent excessive residual coating raw materials at the spray port of the spray pipe 3 from causing dripping;

[0030] A control component 5, the control component 5 is arranged on one side of the spray pipe 3, and the control component 5 is used to drive the cleaning component 4 to clean the residual coating raw materials at the spray port of the spray pipe 3;

[0031] The collection component 6 is arranged below the cleaning component 4, and the collection component 6 is used to collect the coated raw material after being cleaned by the cleaning component 4.

[0032] Place the product to be coated on the conveying device 2 and convey it into the coating machine body 1 through the conveying device 2. The coating machine body 1 coats the coated raw material on the product substrate through the nozzle 3. Through the control component 5, the cleaning component 4 is used to clean the residual coated raw material at the lower nozzle of the nozzle 3, preventing excessive residual coated raw material at the lower nozzle of the nozzle 3, which may cause dripping of the coated raw material and affect the coating effect of the product. After the cleaning component 4 finishes cleaning the residual coated raw material at the nozzle of the nozzle 3, it can be centrally collected through the collection component 6, and the collected coated raw material can be reused to reduce waste of the coated raw material.

[0033] Embodiment 2

[0034] The cleaning component 4 includes a sliding sleeve 41 sleeved on the nozzle 3. A scraping plate 42 is arranged below the sliding sleeve 41. The upper end of the scraping plate 42 abuts against the lower end of the sliding sleeve 41. A collection box 43 is fixedly arranged at the lower end of the scraping plate 42. A silica gel soft pad can be arranged on the upper end surface of the scraping plate 42. When the scraping plate 42 scrapes the residual coated raw material at the nozzle of the nozzle 3, the setting of the silica gel soft pad can avoid large wear between the scraping plate 42 and the nozzle 3.

[0035] Initially, the cleaning component 4 is located above the lower nozzle of the nozzle 3 (as Figure 2 shown), so as not to affect the coating of the product by the nozzle 3. After multiple coatings, when there is a large amount of residual coated raw material at the nozzle of the nozzle 3, through the control component 5, the rod 56 of the control component 5 moves downward, thereby driving the cleaning component 4 to move downward. When the lower end surface of the sliding sleeve 41 of the cleaning component 4 is flush with the lower nozzle of the nozzle 3, the cleaning component 4 stops moving downward. Through the control component 5, the rod 56 rotates, thereby driving the scraping plate 42 and the collection box 43 to rotate, so that the scraping plate 42 scrapes the residual coated raw material at the nozzle of the nozzle 3. The scraped coated raw material will flow into the collection box 43 for collection. After the cleaning is completed, the control component 5 controls the cleaning component 4 to move upward and return to the initial position.

[0036] The control component 5 includes a connection block 51 fixedly arranged above the nozzle 3. A micro motor 52 is fixedly arranged below the connection block 51. The output shaft of the micro motor 52 is key-connected to the rotating rod 53. A first gear 54 is fixedly arranged at the lower end of the rotating rod 53.

[0037] A spiral groove 510 is formed on the rotating rod 53. A limiting sleeve 59 is sleeved on the rotating rod 53. A limiting block 512 adapted to the spiral groove 510 is fixedly arranged at the inner end of the limiting sleeve 59, and the limiting block 512 slides in the spiral groove 510.

[0038] On both sides of the limiting sleeve 59, support plates 55 are symmetrically and fixedly arranged. On the lower side of the support plate 55 close to the spray pipe 3, a support rod 56 is rotatably arranged through a bearing. The lower end of the support rod 56 penetrates through the sliding sleeve 41 and is fixedly connected to the scraping plate 42. The support rod 56 is rotatably connected to the sliding sleeve 41. On the support plate 55 on the side away from the spray pipe 3, a limiting rod 58 is slidably arranged. The limiting rod 58 is fixedly connected to the upper end of the connecting block 51. The limiting rod 58 can play a role in guiding and limiting the limiting sleeve 59, so that when the rotating rod 53 rotates, the limiting sleeve 59 moves up and down along the rotating rod 53 and will not rotate with the rotating rod 53.

[0039] When it is necessary to clean the residual coating raw material at the nozzle of the spray pipe 3, the switch is turned on to start the micro motor 52. The output end of the micro motor 52 drives the rotating rod 53 to rotate. Through the arrangement of the limiting rod 58, the limiting block 512 slides down along the spiral groove 510, so that the limiting sleeve 59 moves down along the rotating rod 53, and further the support rod 56 drives the cleaning assembly 4 to move down.

[0040] An annular groove 511 communicating with the spiral groove 510 is formed on the lower side of the rotating rod 53. The limiting block 512 can slide in the annular groove 511. A spiral plate 513 is rotatably arranged at the lower end of the rotating rod 53 located in the spiral groove 510. A tension spring 514 is arranged between the spiral plate 513 and the lower end of the spiral groove 510. The lower end of the spiral plate 513 abuts against the lower end of the annular groove 511.

[0041] When the support rod 56 drives the cleaning assembly 4 to move down until the lower end face of the sliding sleeve 41 is flush with the lower nozzle of the spray pipe 3, the limiting block 512 will slide into the annular groove 511 through the spiral plate 513. When the rotating rod 53 continues to rotate, the limiting block 512 slides in the annular groove 511, so that the limiting sleeve 59 will not continue to move down, and further the cleaning assembly 4 will not continue to move down, maintaining the position where the lower end face of the sliding sleeve 41 is flush with the lower nozzle of the spray pipe 3. The arrangement of the tension spring 514 can make the lower end of the spiral plate 513 return to the position abutting against the lower end face of the annular groove 511 after the limiting block 512 slides past the spiral plate 513. After the cleaning assembly 4 finishes cleaning, the micro motor 52 drives the rotating rod 53 to rotate in the reverse direction, so that the limiting block 512 can slide up into the spiral groove 510 through the spiral plate 513, so that the limiting sleeve 59 moves up, and further the cleaning assembly 4 moves up and returns to the initial position.

[0042] A second gear 57 that can be meshed with the first gear 54 is slidably sleeved on the upper side of the support rod 56. A slide rod 515 is fixedly arranged in the middle of the second gear 57. A through groove 516 adapted to the slide rod 515 is formed through the upper side of the support rod 56. The second gear 57 slides in the through groove 516 through the slide rod 515.

[0043] Initially, under the action of its own weight, the second gear 57 is located at the lowermost side of the through groove 516. When the support rod 56 drives the cleaning assembly 4 to move down until the lower end face of the sliding sleeve 41 is flush with the lower nozzle of the spray pipe 3, the second gear 57 moves down to mesh with the first gear 54. When the micro motor 52 drives the rotating rod 53 to continue rotating, it will also drive the first gear 54 to rotate, thereby driving the second gear 57 to rotate. Through the sliding rod 515, the support rod 56 can be rotated, and then the scraper 42 is driven to rotate, so that the scraper 42 scrapes the residual coating raw material at the nozzle of the spray pipe 3. After the cleaning assembly 4 completes the cleaning, the upward movement of the limit sleeve 59 will drive the support rod 56 to move up, separating the second gear 57 from the first gear 54, so that the scraper 42 stops rotating, so as not to affect the upward movement of the cleaning assembly 4;

[0044] The setting of the sliding rod 515 and the through groove 516 is such that when the support rod 56 drives the second gear 57 to move down and mesh with the first gear 54, if the tooth grooves of the second gear 57 and the first gear 54 do not correspond up and down, the second gear 57 will slide upward along the through groove 516 through the sliding rod 515. When the first gear 54 continues to rotate until the tooth grooves correspond up and down with the second gear 57, the second gear 57 will fall downward into the tooth groove of the first gear 54 under the action of its own weight, so that the second gear 57 meshes with the first gear 54.

[0045] Embodiment Three

[0046] The collection assembly 6 includes a through hole 61 formed through the bottom end of the collection box 43. The center line of the through hole 61 and the center line of the support rod 56 are on the same vertical line, so that when the collection box 43 rotates together with the scraper 42, the end of the flow pipe 62 connected to the through hole 61 also rotates around the center line of the support rod 56. A flow pipe 62 is rotatably arranged below the through hole 61. The other end of the flow pipe 62 is communicated with a collection box, and a recovery pump is arranged in the collection box. On the basis of Embodiment One and Embodiment Two, when there is more coating raw material stored in the collection box 43, the coating raw material in the collection box 43 can be collected into the collection box through the recovery pump, so as to facilitate the reuse of the collected coating raw material and reduce the waste of the coating raw material.
