[0002] Plastering gypsum is a gypsum material specially used for building plastering construction. Compared with ordinary gypsum (usually model gypsum or decorative gypsum), it has certain differences in physical and chemical properties. Common problems in the mixing process of plastering gypsum include uneven mixing, caking, bubbling, unstable setting time, poor fluidity and slurry separation. The main causes of these problems involve the control of equipment, raw material quality, water-cement ratio, admixture ratio and mixing time. By reasonably selecting mixing equipment, strictly controlling the ratio, adjusting the mixing time and operating procedures, these problems can be effectively solved to ensure the construction performance and finished product quality of plastering gypsum.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] An embodiment of a continuous plastering gypsum production device of the present invention is as follows Figures 1 to 14 As shown, it includes a storage mechanism 1 for mixing plaster gypsum and a power mechanism 2 for providing power, the power mechanism 2 is installed at the upper end of the storage mechanism 1, and also includes a stirring mechanism 4 for stirring the plaster gypsum material and a follower mechanism 3 for adjusting the stirring state of the stirring mechanism 4, the stirring mechanism 4 is installed at the power output end of the power mechanism 2, and the follower mechanism 3 is installed between the stirring mechanism 4 and the power mechanism 2;

[0036] like Figure 3 As shown, the follower mechanism 3 includes a follower sleeve 31, which is mounted on the main shaft 22 of the power mechanism 2, and the stirring mechanism 4 is provided with a plurality of groups, and the circumferential array is evenly mounted outside the follower mechanism 3;

[0037] like Figure 7 As shown, the stirring mechanism 4 includes a stirring rod 42, a fixed disk 43 is installed at one end of the stirring rod 42 away from the power mechanism 2, a gravity disk 44 is slidably installed at one end of the stirring rod 42 close to the power mechanism 2, a group of stirring blades 41 are arranged between the fixed disk 43 and the gravity disk 44, a group of stirring blades 41 has two, and are symmetrically arranged about the axis of the stirring rod 42, one end of the stirring blade 41 is movably connected to the fixed disk 43, and the other end of the stirring blade 41 is connected to the gravity disk 44 through an adjusting block 45, the adjusting block 45 is connected to the stirring rod 42 through an adjusting mechanism 5, and the adjusting mechanism 5 is used to adjust the flipping state of the stirring blade 41.

[0038] In this embodiment, if Figure 5 As shown, the follower mechanism 3 also includes an active adjustment disk 32, which is arranged inside the follower sleeve 31, and the stirring rod 42 extends into the follower sleeve 31 to connect to the passive gear 34 located inside the follower sleeve 31. The top of the passive gear 34 is provided with an active adjustment disk 32 for driving the passive gear 34 to rotate. The active adjustment disk 32 is key-connected to the main shaft 22 of the power mechanism 2. The power of the main shaft 22 is transmitted to the passive gear 34 through the active adjustment disk 32, thereby driving the passive gear 34 to rotate. When the passive gear 34 rotates, it can drive the stirring rod 42 to change the opening direction of the stirring blade 41.

[0039] In this embodiment, if Figure 4 As shown, a return spring 33 is arranged near the top inside the follower sleeve 31, one end of the return spring 33 is connected to the follower sleeve 31, and the other end of the return spring 33 is connected to the main shaft 22. When the follower sleeve 31 is in the initial position, the return spring 33 is in the initial state, thereby ensuring that the return spring 33 can provide elastic fluctuations between the main shaft 22 and the follower sleeve 31 during the subsequent torsion process.

[0040] In this embodiment, if Figure 5 and Fig.14 As shown, a limiting block is formed on the side of the passive gear 34, and a limiting groove for limiting the rotation of the passive gear 34 and the limiting block by 180° is formed inside the follower sleeve 31.

[0041] In this embodiment, if Figure 7-Figure 10As shown, the adjustment mechanism 5 includes a limit ring 51, which is arranged on the stirring rod 42, and the limit ring 51 is located between the fixed disk 43 and the gravity disk 44 and close to one side of the gravity disk 44, a support spring 52 is arranged between the limit ring 51 and the gravity disk 44, a slide groove 53 is formed on the fixed disk 43 to prevent the gravity disk 44 from rotating, a rotating block 46 is arranged inside the gravity disk 44, the rotating block 46 and the adjustment block 45 are key-connected, an extrusion block 55 is installed on the side of the rotating block 46 close to the slide groove 53, and an extrusion groove 54 matching the extrusion block 55 is arranged on the slide groove 53, and the extrusion block 55 slides inside the extrusion groove 54 to drive the rotating block 46 to rotate.

[0042] In this embodiment, the rotation range of the rotating block 46, the adjusting block 45 and the stirring blade 41 is 0° to 45°, and the two stirring blades 41 symmetrically arranged up and down rotate in opposite directions.

[0043] In this embodiment, five groups of stirring mechanisms 4 are arranged outside the follower mechanism 3 , and each group has four stirring mechanisms.

[0044] In this embodiment, the stirring blade 41 is made of elastic steel sheet.

[0045] In this embodiment, the output shaft 21 is fixedly connected to the top of the main shaft 22 , and a stirring disc is installed at the bottom of the main shaft 22 .

[0046] In this embodiment, the stirring blade 41 is connected to the fixing plate 43 via a pin shaft.

[0047] The working principle is as follows: in the initial state, because the reset spring 33 provides potential energy between the main shaft 22 and the follower sleeve 31, the active adjustment disk 32 does not drive the passive gear 34 and the stirring rod 42 to rotate, and the gravity disk 44 is not affected by the centrifugal force. The gravity disk 44 is supported by the support spring 52 and is located near the side of the follower sleeve 31. At this time, the stirring blade 41 is stretched and stretched. When observed from the side, the stirring blade 41 is Fig.11 As shown;

[0048] When the motor of the power mechanism 2 is started, the main shaft 22 is driven to rotate through the output shaft 21. Since the main shaft 22 is not directly connected to the follower sleeve 31, the main shaft 22 rotates through the active adjustment disk 32 in cooperation with the passive gear 34. Since a limit block is provided on the upper side of the passive gear 34, after cooperating with the limit groove inside the follower sleeve 31, the follower sleeve 31 is driven to rotate. At the same time, since the passive gear 34 is driven to rotate by the active adjustment disk 32, the passive gear 34 drives the stirring rod 42 to rotate, and the stirring blade 41 is also driven to rotate synchronously. Figure 11 to Figure 12 , at which time the stirring blade 41 is in a straight state, and the tangential contact surface between the stirring blade 41 and the plastering gypsum is minimal, thereby reducing the resistance of the plastering gypsum to the stirring blade 41, and the whole device is easier to rotate;

[0049] When the speed increases, the centrifugal force on the gravity plate 44 becomes greater and greater, and the gravity plate 44 will expand and move outward. When the gravity plate 44 moves, it will drive the rotating block 46 inside the gravity plate 44 to move. Because the bottom of the rotating block 46 cooperates with the extrusion groove 54 through the extrusion block 55, the rotating block 46 rotates when it moves horizontally, and synchronously drives the stirring blade 41 to rotate through the adjustment block 45, so that Figure 12 to Figure 13 Because the stirring blades 41 are squeezed by the gravity disk 44, they will bend, and the two stirring blades 41 will form a bucket shape as shown in the matching mechanism 7, thereby impacting the plastering gypsum for stirring, and because the stirring blades 41 are thin sheets, when the speed increases, the fluid plastering gypsum quickly flows through the upper and lower sides of the two stirring blades 41. Due to the Karman vortex street principle, the plastering gypsum fluid passing through the upper and lower sides of the same set of stirring blades 41 will form staggered vortices (such as Fig.13 As shown by the upper arrow, the degree of chaos of the plaster during the mixing process is increased, and a stable vortex is avoided from forming. Moreover, since a stirring rod 42 is provided between the two stirring blades 41, the stirring rod 42 can destroy the fluid structure passing through the two stirring blades 41, and further avoid the formation of a stable stirring state, thereby improving the stirring efficiency through the chaotic state.

[0050] In addition, during the stirring process, the stirring blades 41 are caused to form stirring states in different directions by controlling the forward and reverse rotation of the motor on the power mechanism 2, thereby improving the stirring efficiency.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
