Those of ordinary skill in the art can adjust or modify these devices and environments according to specific needs. Detailed implementation manners

[0042] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0043] Embodiment: As Figures 1 to 8 shown, an embodiment of the present invention provides a sealant preparation and processing device, including a reaction tank body 1, a fan blade cleaning mechanism 3, and an inner wall scraping mechanism 5;

[0044] A discharge port 11 is provided at the bottom of the reaction tank body 1, and a control valve is provided on the discharge port 11. A feed hopper 12 is provided on the outer wall of the reaction tank body 1 near the top. A driving motor 2 is installed on the top of the reaction tank body 1. A stirring shaft 21 is vertically arranged at the center of the interior of the reaction tank body 1. The top end of the stirring shaft 21 is rotatably connected to the reaction tank body 1 and extends outside the reaction tank body 1 and is fixedly connected to the output end of the driving motor 2. A plurality of groups of stirring blades 22 are symmetrically and fixedly connected along the axial direction on both sides of the stirring shaft 21. The raw materials for preparing the sealant are put into the reaction tank body 1 through the feed hopper 12. The driving motor 2 works to drive the stirring shaft 21 to drive the stirring blades 22 to rotate, and the sealant is prepared by stirring and mixing. After the preparation is completed, the control valve is opened to discharge the prepared sealant from the discharge port 11.

[0045] In this embodiment, the fan blade cleaning mechanism 3 includes two semi-axis sleeves 31 sleeved outside the stirring shaft 21. The semi-axis sleeve 31 is fixedly connected with a cleaning scraping sleeve 32. The cleaning scraping sleeve 32 is sleeved outside the stirring blade 22. The fan blade cleaning mechanism 3 further includes a rotating plate 33 arranged above the semi-axis sleeve 31. A through hole 331 for the stirring shaft 21 to pass through is opened at the center of the rotating plate 33. The bottom of the rotating plate 33 is fixedly connected to the stirring shaft 21 through a connecting frame 332. A position adjusting component is arranged between the semi-axis sleeve 31 and the rotating plate 33. The position adjusting component is used to drive the semi-axis sleeve 31 and the cleaning scraping sleeve 32 to move along the length direction of the stirring blade 22. When the stirring shaft 21 and the stirring blades 22 rotate to stir and mix the raw materials for preparing the sealant, the two semi-axis sleeves 31 are sleeved and attached to the outside of the stirring shaft 21, and the rotating plate 33 rotates synchronously with the stirring shaft 21. When cleaning is carried out after the sealant is prepared, the position adjusting component is used to drive the semi-axis sleeve 31 and the cleaning scraping sleeve 32 to move, so that the cleaning scraping sleeve 32 moves along the length direction of the stirring blade 22, thereby scraping off the sealant adhered to the stirring blade 22 cleanly, reducing the residue of the sealant, and reducing the waste of the sealant.

[0046] In this embodiment, first long strip through slots 333 are symmetrically formed on both sides of the rotating plate 33. The first long strip through slots 333 extend from the outside of the reaction tank body 1 towards its center point. The position adjusting assembly includes a reciprocating lead screw 34 rotatably connected in the first long strip through slots 333. A linkage plate 36 is fixedly connected to the outer side of the top of the half shaft sleeve 31. One end of the linkage plate 36 is slidably connected in the first long strip through slots 333 and sleeved outside the reciprocating lead screw 34. The linkage plate 36 is connected to the outside of the reciprocating lead screw 34 through balls. The reciprocating lead screw 34 drives the linkage plate 36 to move axially along it. One end of the reciprocating lead screw 34 extends into the through hole 331 and is fixedly connected with a first bevel gear 35. Above the first bevel gear 35 and sleeved outside the stirring shaft 21, there is a second bevel gear 37. The second bevel gear 37 cooperates with the two first bevel gears 35. Between the top of the second bevel gear 37 and the reaction tank body 1, there is a meshing adjustment structure 38. The meshing adjustment structure 38 is used to adjust the height of the second bevel gear 37 to make the second bevel gear 37 mesh with or disengage from the first bevel gear 35. During cleaning, the second bevel gear 37 is pushed downward through the meshing adjustment structure 38, so that the second bevel gear 37 contacts and meshes with the two first bevel gears 35. The second bevel gear 37 does not rotate. Under the action of the rotation of the rotating plate 33, the two first bevel gears 35 are driven to rotate around the second bevel gear 37, so that the first bevel gears 35 mesh and rotate. The reciprocating lead screw 34 is driven to rotate through the first bevel gear 35, thereby driving the linkage plate 36 to reciprocate axially along the reciprocating lead screw 34. The linkage plate 36 drives the half shaft sleeve 31 and the cleaning scraping sleeve 32 to reciprocate along the length direction of the stirring fan blades 22, and scrapes off the sealant adhered to the stirring fan blades 22.

[0047] In this embodiment, the meshing adjustment structure 38 includes a fixed collar 381 sleeved outside the stirring shaft 21. An outer fixed ring plate 382 is fixedly connected to the outer side of the top of the fixed collar 381. The outer fixed ring plate 382 is fixedly connected to the inner top of the reaction tank body 1. A moving collar 383 is slidably connected to the outside of the outer fixed ring plate 382. A pushing member 384 is fixedly connected between the bottom of the outer fixed ring plate 382 and the top of the second bevel gear 37. The pushing member 384 is one of a hydraulic cylinder, a telescopic cylinder, etc. The pushing member 384 works to push the second bevel gear 37 to move up and down, so that the position of the second bevel gear 37 changes, realizing the meshing or disengaging state between the second bevel gear 37 and the two first bevel gears 35. Through the arranged fixed collar 381 and moving collar 383, and a plurality of guiding grooves are axially formed on the inner wall of the moving collar 383, and a plurality of guiding strips placed in the guiding grooves are axially arranged on the outer wall of the fixed collar 381. The moving collar 383 and the fixed collar 381 play a role of limiting when in place through the guiding grooves and guiding strips, so that the moving collar 383 and the fixed collar 381 can be telescopic and restricted from rotating, to ensure that the second bevel gear 37 does not rotate.

[0048] In this embodiment, a support assembly 4 is disposed inside the reaction tank body 1 and below the rotating plate 33. The support assembly 4 includes a fixed ring seat 41 fixedly connected to the inside of the reaction tank body 1. A rotating ring 42 is rotatably connected to the top of the fixed ring seat 41. A plurality of retention jacks 421 are equidistantly arranged along the circumferential direction at the top of the rotating ring 42. The rotating plate 33 is disposed on the top of the rotating ring 42. A plurality of retention posts fixedly connected to the bottom of the rotating plate 33 are inserted into the retention jacks 421. The rotating plate 33 and the rotating ring 42 are assembled by inserting the retention posts into the retention jacks 421, and under the supporting action of the fixed ring seat 41, the outside of the rotating ring 42 is supported to improve the stability of the rotating ring 42 during rotation.

[0049] In this embodiment, the inner wall scraping mechanism 5 includes a sliding sleeve 51 movably sleeved on one end of the stirring fan blade 22 away from the stirring shaft 21. Side wall scrapers 52 are arranged between the sliding sleeves 51 on the same side. The side wall scrapers 52 are vertically arranged. A bottom scraper 53 horizontally arranged is fixedly connected to the bottom of the side wall scrapers 52. A fixed rod 54 is fixedly connected to the top of the side wall scrapers 52. A height adjusting assembly 56 is arranged between the fixed rod 54 and the rotating plate 33. The height adjusting assembly 56 is used to adjust the height of the side wall scrapers 52 so that the side wall scrapers 52 and the bottom scraper 53 are separated from the inner wall of the reaction tank body 1. When stirring and mixing the raw materials for preparing the sealant, the height of the side wall scrapers 52 is adjusted by the height adjusting assembly 56, so that the side wall scrapers 52 are separated from the inner side wall of the reaction tank body 1, and the bottom scraper 53 is separated from the inner bottom end of the reaction tank body 1. During the stirring and mixing process, the side wall scrapers 52 and the bottom scraper 53 do not contact the reaction tank body 1, avoiding the wear of the side wall scrapers 52 and the bottom scraper 53 and improving the service life.

[0050] In this embodiment, the length of the bottom scraper 53 is greater than the radius of the reaction tank body 1, so that the two bottom scrapers 53 are staggered, and the entire area of the bottom of the reaction tank body 1 can be scraped. Connecting rods are fixedly connected to the ends of the two bottom scrapers 53 away from the side wall scrapers 52 to improve the stability of the bottom scraper 53. The cross section of the side wall scraper 52 is a triangular structure, and its two inclined surfaces are arc surfaces, facing the rotation direction of the side wall scraper 52. During stirring and mixing, the sealant can flow and turbulently flow from both side surfaces of the side wall scraper 52, improving the mixing effect of the sealant.

[0051] In this embodiment, the fixed rod 54 includes a first vertical section 541 connected to the side wall scraper 52, a horizontal section 542 arranged at the top of the first vertical section 541, and a second vertical section 543 arranged at one end of the horizontal section 542 away from the first vertical section 541;

[0052] On both sides of the rotating plate 33, second long through slots 334 are symmetrically formed. The second long through slots 334 are arranged in parallel with the first long through slots 333. The height adjustment assembly 56 includes a sliding seat 561 slidably connected in the second long through slots 334. A fixed cover 562 is fixedly connected to the top of the sliding seat 561. The top end of the second vertical section 543 of the fixed rod 54 slidably penetrates through the sliding seat 561 and is disposed inside the fixed cover 562 and fixedly connected with a magnet 563. A first electromagnet 564 is fixedly connected to the inner top of the fixed cover 562. A second electromagnet 565 is fixedly connected to the top of the sliding seat 561 and located inside the fixed cover 562. The first electromagnet 564 and the second electromagnet 565 are used in cooperation with the magnet 563. An elastic member 567 is fixedly connected between one side of the sliding seat 561 close to the stirring shaft 21 and the inner wall of the second long through slot 334. The elastic member 567 is a helical spring;

[0053] On one side of the side wall scraper 52, a slide bar 521 is arranged along the length direction. A sliding groove is formed on the outer side of the sliding sleeve 51. The side wall scraper 52 and the sliding sleeve 51 are slidably connected through the slide bar 521 and the sliding groove. By providing the slide bar 521 and the sliding groove, the side wall scraper 52 can slide and move on the sliding sleeve 51 to adjust the position;

[0054] A mating ring 55 is fixedly connected to the inner wall of the reaction tank body 1 at the position of the fixed rod 54. The bottom of the mating ring 55 is provided with an inclined surface. The inclined surface is inclined upward from the outside of the reaction tank body 1 towards its center. A roller 544 is rotatably connected to the joint of the first vertical section 541 and the horizontal section 542 of the fixed rod 54. A ball 545 is arranged on the side wall of the first vertical section 541 of the fixed rod 54 and below the roller 544.

[0055] In the specific implementation process, when stirring and mixing the raw materials for preparing the sealant, the first electromagnet 564 is in the energized state and the second electromagnet 565 is in the de-energized state. At this time, the magnet 563 is adsorbed and fixed to the first electromagnet 564, driving the fixed rod 54 to move upward. The fixed rod 54 drives the side wall scraper 52 to move upward, and the side wall scraper 52 drives the bottom scraper 53 to move upward, so that the bottom scraper 53 is separated from the inner bottom end of the reaction tank 1. At the same time, the roller 544 on the fixed rod 54 slides on the inclined surface of the mating ring 55 until the ball 545 contacts the inner wall of the mating ring 55. The fixed rod 54 drives the sliding seat 561 to move inside the sliding seat 561 and squeeze the elastic member 567, realizing the lateral adjustment of the position of the side wall scraper 52 and separating the side wall scraper 52 from the inner side wall of the reaction tank 1, so as to avoid the side wall scraper 52 and the bottom scraper 53 contacting the reaction tank 1 during the stirring and mixing process; during cleaning, the first electromagnet 564 is in the de-energized state and the second electromagnet 565 is in the energized state. At this time, the magnet 563 is adsorbed and fixed to the second electromagnet 565, driving the fixed rod 54 to move downward. The fixed rod 54 drives the side wall scraper 52 and the bottom scraper 53 to move downward, so that the bottom scraper 53 contacts the inner bottom end of the reaction tank 1. At the same time, the second vertical section 543 of the fixed rod 54 is placed at the mating ring 55 to avoid the position of the mating ring 55. Under the action of the elastic member 567, the side wall scraper 52 is pushed to contact the inner side wall of the reaction tank 1. By the rotation of the stirring shaft 21, the side wall scraper 52 and the bottom scraper 53 are driven to rotate inside the reaction tank 1, scraping off the sealant adhered to the inner wall of the reaction tank 1, reducing the residue of the sealant and the waste of the sealant.

[0056] This embodiment also provides a processing method for a sealant preparation and processing device, including the following steps:

[0057] S1. Put the raw materials for preparing the sealant into the reaction tank 1 through the feed hopper 12. Drive the stirring shaft 21 to drive the stirring fan blades 22 to rotate through the operation of the drive motor 2, stir and mix the raw materials to prepare the sealant. After the sealant is prepared, open the control valve to discharge the prepared sealant from the discharge port 11.

[0058] S2. After the sealant in the reaction tank 1 is discharged, drive the half shaft sleeve 31 and the cleaning scraper sleeve 32 to move through the position adjustment assembly, so that the cleaning scraper sleeve 32 moves along the length direction of the stirring fan blades 22, thereby scraping off the sealant adhered to the stirring fan blades 22 completely.

[0059] In step S2, during cleaning, the second bevel gear 37 is pushed downward by the working of the pusher 384, so that the second bevel gear 37 contacts and meshes with the two first bevel gears 35. Under the action of the rotation of the rotating plate 33, the two first bevel gears 35 are driven to rotate around the second bevel gear 37, causing the first bevel gears 35 to mesh and rotate. The first bevel gears 35 drive the reciprocating lead screw 34 to rotate, driving the linkage plate 36 to reciprocate axially along the reciprocating lead screw 34. The linkage plate 36 drives the half shaft sleeve 31 and the cleaning scraping sleeve 32 to reciprocate along the length direction of the stirring fan blade 22, scraping off the sealant adhered to the stirring fan blade 22;

[0060] S3.
