Description

Technical Field

[0001] The invention relates to the technical field of building construction, and more specifically to a mixing production process for building coatings. Background Art

[0002] Paint is applied to the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the coated object. It is usually based on resin, oil, or emulsion. The mixing method of paint is mostly manual stirring, that is, pouring multiple paints or powders and liquids into a mixing tank and then stirring them manually.

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0042] Embodiment 1

[0043] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0044] like Figures 1 to 19As shown, a construction coating mixing production process includes a mixing drum 1, a stirring shaft 2 is arranged in the mixing drum 1, a feeding assembly 3 is arranged at the upper end of the stirring shaft 2, the feeding assembly 3 includes a feeding tube 31, a feeding hole 32 opened on the feeding tube 31 and a sliding rod 33 slidably arranged in the feeding tube 31, an extrusion assembly 4 is arranged in the middle of the stirring shaft 2, the extrusion assembly 4 includes a plurality of leakage holes 41 opened on the stirring shaft 2 and a plurality of extrusion plates 42 slidably arranged in the stirring shaft 2, a guide assembly 5 is arranged between the extrusion plate 42 and the sliding rod 33, a liquid blocking assembly 6 and a powder blocking assembly 7 driven by the liquid blocking assembly 6 are arranged on the stirring shaft 2, and the liquid blocking assembly 6 includes a float 6 1 and a blocking tube 62 slidably arranged on the inner wall of the stirring shaft 3, the powder blocking component 7 includes a blocking plate 71 rotatably arranged on the feeding tube 31, the feeding tube 31 drives the sliding rod 33 to slide back and forth during the rotation process to discharge the powder through the feeding hole 32, the extrusion component 4 drives the extrusion plate 42 to extrude the liquid from the leakage hole 41 through the guide component 5 when the sliding rod 33 slides back and forth to mix with the powder, the liquid blocking component 6 drives the float 61 to rise after the powder and the liquid are mixed, and the leakage hole 41 is blocked through the blocking tube 62 at the same time, and the powder blocking component 7 drives the blocking tube 62 to rise while driving the blocking plate 71 to block the feeding hole 32.

[0045] It is worth mentioning that Figures 4 to 13 As shown, the feeding assembly 3 also includes a rectangular rod 34 fixedly arranged in the feeding tube 31, a plugging head 35 fixedly arranged on the sliding rod 33, a through groove 36 fixedly opened in the middle of the feeding tube 31, a sliding block 37 fixedly arranged in the middle of the sliding rod 33, a rectangular groove 38 opened on the sliding rod 33, a first spring 39 fixedly arranged between one end of the sliding rod 33 and the feeding tube 31, a guide rail 310 fixedly arranged on the inner wall of the mixing barrel 1, and a feeding rod 311 fixedly arranged on the feeding tube 31, the rectangular groove 38 cooperates with the rectangular rod 34, the plugging head 35 cooperates with the feeding hole 32, the surface of the guide rail 310 is set to a wavy structure, and the other end of the sliding rod 33 is set to a spherical shape and is aligned with the guide rail 310 The surfaces are matched, the stirring shaft 2 is fixedly connected to the discharge pipe 31, and the sliding block 37 is matched with the through groove 36, wherein the powder is transported to the discharge pipe 31 through the loading rod 311 and the discharge pipe 31 is always full of powder. When in use, when the loading rod 311, the discharge pipe 31 and the stirring shaft 2 are rotating, the sliding rod 33 is driven to slide on the guide rail 310, so that the sliding rod 33 and the blocking head 35 move back and forth, so that the blocking head 35 indirectly cooperates with the discharge hole 32, and the powder falls indirectly. By means of dispersed falling, accumulation is reduced, and blockage is prevented when the powder is discharged, which is more conducive to stirring. In addition, the sliding block 37 is always in contact with the through groove 36 when sliding back and forth, so as to prevent the powder from falling into the through groove 36.

[0046] In addition, if Figures 3 to 14As shown, the extrusion assembly 4 also includes an upper liquid channel 43 opened in the stirring shaft 2, a liquid storage chamber 44 opened on the upper liquid channel 43, and a guide rod 45 fixedly arranged on the extrusion plate 42. The leakage hole 41 is obliquely opened on the liquid storage chamber 44. The upper and lower ends of the extrusion plates 42 are in contact with the two ends of the liquid storage chamber 44. A one-way valve is arranged on the upper liquid channel 43, wherein a water pump is connected to the upper liquid channel 43 to transport the liquid material to the liquid storage chamber 44 through the upper liquid channel 43, so that the liquid storage chamber 44 is always filled with liquid. The upper liquid channel 43 is filled with liquid. In addition, when the powder and the liquid are mixed and reach the set liquid level, the water pump stops working, and the one-way valve prevents the liquid from flowing back from the liquid storage chamber 44 to the upper liquid channel 43. When in use, when the lower material pipe 31 reciprocates, it drives the extrusion plate 42 to reciprocate, squeezes the liquid, and applies a certain pressure to make the liquid splash out from the leakage hole 41, and fully contact with the falling powder to achieve the effect of pre-mixing, and then the stirring blade at the bottom of the stirring shaft 2 stirs it to improve the mixing effect.

[0047] It should be further explained that if Figures 3 to 13 As shown, the guide assembly 5 includes a accommodating chamber 51 opened on the liquid storage chamber 44, a rotating rod 52 rotatably set on the liquid storage chamber 44, guide rails 53 fixedly set on both sides of the rotating rod 52, a gear 54 fixedly set on the rotating rod 52, and a rack 55 fixedly set on the sliding block 37. The gear 54 is meshed with the rack 55. The surface of the guide rail 53 is set to a wavy structure. The bottom of the guide rod 45 is set to a spherical shape and matches the surface of the guide rail 53. The liquid storage chamber 44 and the inner wall of the accommodating chamber 51 are provided with a cavity 56. When in use, the feeding tube 31 reciprocates when it drives the rack 55 to reciprocate, drives the gear 54, the rotating rod 52 and the guide rail 53 to reciprocate, so that the guide rod 45 and the extrusion plate 42 slide back and forth in the liquid storage chamber 44 to extrude the liquid material, thereby improving the effect of the liquid material spraying.

[0048] It should be emphasized that if Fig.15 and Fig.16As shown, the liquid blocking component 6 also includes a slider 63 fixedly arranged on the blocking tube 62, a slide groove 64 opened on the liquid storage cavity 44, and a plurality of connecting tubes 65 obliquely arranged on the blocking tube 62. The blocking tube 62 cooperates with the cavity 56, the slider 63 cooperates with the slide groove 64, the connecting tube 65 cooperates with the leakage hole 41, and the inner wall of the float 61 cooperates with the outer wall of the stirring shaft 2. The blocking tube 62 slides in the slide groove 64 through the slider 63, which plays a limiting role on the blocking tube 62, so that the connecting tube 65 corresponds to the leakage hole 41. During use, when the powder and liquid are mixed and the liquid level of the mixed liquid drives the float 61 to rise, at this time, the buoyancy drives the float 61 to rise, and the magnetic attraction between the float 61 and the blocking tube 62 can drive the blocking tube 62 to rise, and the blocking tube 62 drives the connecting tube 65 to rise. The connecting tube 65 is staggered with the leakage hole 41, so that the liquid cannot flow out of the leakage hole 41, and the leakage hole 41 is blocked, thereby achieving the effect of automatic blocking and quantitative stirring.

[0049] It is worth mentioning that Figures 15 to 19 As shown, the powder blocking assembly 7 also includes hydraulic grooves 72 provided in the inner walls on both sides of the feeding tube 31, arc grooves 73 provided on the hydraulic grooves 72, arc blocks 74 slidably arranged in the arc grooves 73, second springs 75 fixedly arranged between the arc blocks 74 and the arc grooves 73, connecting grooves 76 provided on both sides of the accommodating cavity 51, and slots 77 provided on the blocking plate 71. The connecting grooves 76, the hydraulic grooves 72, and the arc grooves 73 are connected, and the arc blocks 74 are fixedly connected to the blocking plate 71. Among them, the cavity 56, the hydraulic grooves 72, and the arc grooves 73 are connected. Hydraulic oil is provided in the connecting groove 76. The initial state of the blocking plate 71 is that the slot 77 is located at the discharge hole 32, so that the powder is discharged from the discharge hole 32. When in use, when the blocking tube 62 rises, it pushes the hydraulic oil, so that the hydraulic oil passes through the connecting groove 76 and the hydraulic groove 72 to reach the arc groove 73, pushing the arc block 74 to slide in the arc groove 73, so that the blocking plate 71 rotates until the slot 77 is offset from the discharge hole 32. The blocking plate 71 blocks the discharge hole 32, so that the powder cannot be discharged, thereby achieving the effect of automatic blocking.

[0050] Further, such as Fig.16 As shown, magnets are provided on the inner wall of the float 61 and the bottom of the plugging tube 62 and the two attract each other. The plugging tube 62 follows the float 61 to rise and fall by means of magnetic attraction. When the powder and liquid are mixed, they are discharged through the discharge port. When the liquid level drops, the float 61 drives the plugging tube 62 to descend and reset, so that the connecting tube 65 is connected with the leakage hole 41. At the same time, the hydraulic oil drives the plugging plate 71 to rotate, so that the groove 77 corresponds to the discharge hole 32, preparing for the next mixing.

[0051] In addition, if Fig.16As shown, a limit block 8 is fixedly provided on the stirring shaft 2 and the limit block 8 cooperates with the float 61. The limit block 8 plays a limiting role when the float 61 descends, preparing for the next ascent.

[0052] like Figure 1 As shown, the mixing barrel 1 is also provided with a barrel cover 9, a fixing sleeve 10 fixedly arranged on the barrel cover 9, and a fixing rod 11 fixedly arranged on the fixing sleeve 10, and a feeding rod 311 cooperates with the fixing sleeve 10 and is connected with the fixing rod 11, wherein a driving device is provided on the barrel cover 9 and the driving device drives the feeding rod 311 to rotate, thereby driving the feeding pipe 31 and the stirring shaft 2 to rotate, the fixing rod 11 is connected to the feeding pipe, and the powder is injected from the feeding pipe into the fixing rod 11 and the feeding rod 311, and the fixing sleeve 10 and the fixing rod 11 are in a stationary state to prevent the feeding pipe from rotating and deforming.

[0053] Embodiment 2

[0054] like Fig.13 As shown, the components that are the same or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that a sealing gasket is provided on the sliding block 37.

[0055] Here, in this embodiment, a sealing gasket is provided on the sliding block 37 to improve the sealing performance of the through groove 36 and prevent powder from falling in.

[0056] Working process

[0057] The powder is injected into the fixed rod 11 and the feeding rod 311 from the material pipe, and the driving device drives the feeding rod 311 to rotate, thereby driving the feeding pipe 31 and the stirring shaft 2 to rotate, driving the sliding rod 33 to slide on the guide rail 310, so that the sliding rod 33 and the plugging head 35 reciprocate, so that the plugging head 35 indirectly cooperates with the feeding hole 32, and the powder falls indirectly. When the feeding pipe 31 reciprocates, it drives the rack 55 to reciprocate, drives the gear 54, the rotating rod 52 and the guide track 53 to reciprocate, and makes the guide rod 45 and the extrusion plate 42 slide reciprocatingly in the liquid storage chamber 44, squeezes the liquid, applies a certain pressure, and makes the liquid splash out from the leakage hole 41 and mix with the falling powder. When the powder and liquid are mixed and the liquid level of the mixed liquid drives the float 61 to rise, the float 61 drives the blocking tube 62 to rise, and the blocking tube 62 drives the connecting tube 65 to rise. The connecting tube 65 is staggered with the leakage hole 41, so that the liquid cannot flow out of the leakage hole 41, and the leakage hole 41 is blocked. While the blocking tube 62 rises, it pushes the hydraulic oil to pass through the connecting groove 76 and the hydraulic groove 72 to reach the arc groove 73, and pushes the arc block 74 to slide in the arc groove 73, so that the blocking plate 71 rotates until the slot 77 is staggered with the discharge hole 32, and the blocking plate 71 blocks the discharge hole 32, so that the powder cannot be discharged, thereby achieving the effect of automatic blocking and quantitative mixing.
