Description
Technical Field
[0001] This utility model belongs to the field of latex powder mixing technology, and in particular relates to a mixing device for the production of redispersible latex powder. Background Technology
[0002] Redispersible latex powder is a water-soluble redispersible powder. This powder can be quickly redispersed into an emulsion after contact with water. Due to its high binding capacity and unique properties, redispersible latex powder has an extremely wide range of applications.
[0003] The production of redispersible latex powder usually requires the use of a stirring device. However, existing unidirectional stirring devices can only rotate in one direction at a time, which is inefficient and has poor adaptability, easily leading to uneven mixing and affecting the overall quality of the stirred product. Therefore, we propose a stirring device for the production of redispersible latex powder. Utility Model Content
[0004] The purpose of this invention is to provide a mixing device for the production of redispersible latex powder. Specifically, by setting up a mixing assembly, the material is poured into the mixing drum through the feed inlet. The motor is started, driving the central bevel gear to rotate. Simultaneously, the central bevel gear drives the top and bottom bevel gears to rotate in opposite directions. The top bevel gear drives the rotating shaft to rotate, which in turn drives the outer mixing paddle to rotate. The bottom bevel gear drives the outer ring to rotate, thus achieving bidirectional rotation. This provides greater adaptability to materials. Compared to unidirectional mixing, this mixing device can complete mixing faster, improving mixing efficiency. It solves the problems of existing unidirectional mixing devices, which can only rotate and mix in one direction at a time, resulting in low efficiency and poor adaptability, easily leading to uneven mixing and affecting the overall quality of the mixed product.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a stirring device for the production of redispersible latex powder, including a support frame, a stirring cylinder fixedly connected to the inside of the support frame by bolts, a motor fixedly connected to the right side surface of the stirring cylinder by bolts, and a feed inlet on the left side of the stirring cylinder;
[0007] The outer surface of the mixing drum is provided with a merging assembly, which includes a mounting half-ring. The back of the mounting half-ring is fixedly connected to the front of the mixing drum by bolts. Two locking blocks are fixedly connected to the top of the mounting half-ring by welding. The mixing drum is provided with a mixing assembly, which includes a fixing frame. A protective shell is fixedly connected to the center of the fixing frame by bolts. Three bevel gears are provided inside the protective shell. The top and bottom bevel gears are rotatably connected to the inner sides of the top and bottom of the protective shell on opposite sides. The right side of the middle bevel gear is fixedly connected to the left output end of the motor by screws. The middle bevel gear drives the top and bottom bevel gears to rotate in opposite directions. The top bevel gear drives the rotating shaft to rotate, which drives the outer stirring paddle to rotate. The bottom bevel gear drives the outer ring to rotate, thus achieving bidirectional rotation. This makes it more adaptable to materials. Compared with unidirectional mixing, this mixing device can complete mixing faster and improve mixing efficiency.
[0008] Furthermore, a rotating shaft is fixedly connected to the bottom of the top bevel gear, and the bottom of the rotating shaft is rotatably connected to the inner side of the bottom of the mixing drum. Several outer stirring blades are fixedly connected to the outer surface of the rotating shaft by welding. The inside of the bottom bevel gear is rotatably connected to the outer surface of the rotating shaft. An outer ring is fixedly connected to the bottom of the bottom bevel gear by bolts. The inside of the outer ring is rotatably connected to the outer surface of the rotating shaft. An inner ring is provided inside the outer ring. Several inner stirring blades are fixedly connected to the side of the inner ring near the rotating shaft. The inside of the inner ring is fixedly connected to the outer surface of the rotating shaft. The arrangement of the stirring blades makes the material mix more evenly and improves the mixing effect.
[0009] Furthermore, a valve is bolted to the bottom of the mixing drum, a cover is inserted into the top of the mixing drum, a handle is fixedly connected to the top of the cover, a merging block is welded to the bottom of the cover, the inner bottom side of the merging block is inserted into the outer surface of the top of the locking block, moving rods are slidably connected to the left and right sides of the merging block, a pulling block is fixedly connected to the opposite sides of the two moving rods, a locking tooth is fixedly connected to the opposite sides of the two moving rods, and a spring is provided on the outer surface of the two moving rods. A flipping block is bolted to the back of the mixing drum, a locking tooth is hinged to the inner side of the locking tooth, and the front of the locking tooth is welded to the back of the cover. The pulling block drives the moving rod to move outward, the moving rod drives the locking tooth to move outward, and the locking tooth no longer locks the locking block. At this time, the handle is lifted upward, the handle drives the cover upward, the cover drives the locking tooth upward, and when pulled to the top, it flips backward, at which point maintenance and cleaning can be performed.
[0010] This utility model has the following beneficial effects:
[0011] 1. This utility model, by setting up a stirring assembly, specifically involves pouring materials into the stirring drum through the feed inlet, starting the motor to drive the central bevel gear to rotate, and the central bevel gear simultaneously driving the top and bottom bevel gears to rotate in opposite directions. The top bevel gear drives the rotating shaft to rotate, the rotating shaft drives the outer stirring paddle to rotate, and the bottom bevel gear drives the outer ring to rotate, thereby achieving bidirectional rotation. This makes it more adaptable to materials, and compared to unidirectional stirring, this stirring device can complete the stirring faster and improve stirring efficiency.
[0012] 2. This utility model uses a combined component, specifically a pull block that moves a moving rod outward, which in turn moves the locking teeth outward, freeing them from locking the block. At this point, the handle is lifted, causing the cover to move upward, which in turn moves the locking teeth upward. When pulled to the top, the cover flips backward, allowing for maintenance and cleaning.
[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The right side is fixedly connected to the left output end of the motor 2 by screws. This utility model sets up a stirring assembly 12. Specifically, the material is poured into the stirring drum 3 from the feed port 4. The motor 2 is started to drive the middle bevel gear 251 to rotate. The middle bevel gear 251 drives the top and bottom bevel gears 251 to rotate in opposite directions. The top bevel gear 251 drives the rotating shaft 125 to rotate. The rotating shaft 125 drives the outer stirring paddle 127 to rotate. The bottom bevel gear 251 drives the outer ring 126 to rotate, thereby achieving bidirectional rotation. This makes it more adaptable to materials. Compared with unidirectional stirring, this stirring device can complete the stirring faster and improve the stirring efficiency.
[0027] A rotating shaft 125 is fixedly connected to the bottom of the top bevel gear 251. The bottom of the rotating shaft 125 is rotatably connected to the inner side of the bottom of the mixing drum 3. Several outer stirring paddles 127 are fixedly connected to the outer surface of the rotating shaft 125 by welding. The inside of the bottom bevel gear 251 is rotatably connected to the outer surface of the rotating shaft 125. An outer ring 126 is fixedly connected to the bottom of the bottom bevel gear 251 by bolts. The inside of the outer ring 126 is rotatably connected to the outer surface of the rotating shaft 125.

[0028] A valve 5 is bolted to the bottom of the mixing drum 3. A cover 111 is inserted into the top of the mixing drum 3. A handle 112 is fixedly connected to the top of the cover 111. A merging block is welded to the bottom of the cover 111. The inner bottom of the merging block is inserted into the outer top surface of the locking block 114. Moving rods 116 are slidably connected to the inside of the left and right sides of the merging block. Pulling blocks are fixedly connected to opposite sides of the two moving rods 116.

Specifically, pulling the block drives the moving rod 116 to move outward. The moving rod 116 drives the locking tooth 117 to move outward. The locking tooth 117 no longer locks the locking block 114. At this time, the handle 112 is lifted upward. The handle 112 drives the cover 111 to move upward. The cover 111 drives the locking tooth 117 to move upward. When pulled to the top, it flips backward. At this time, maintenance and cleaning can be carried out.
[0029] A specific application of this embodiment is as follows: The prepared material is slowly poured into the mixing drum 3 through the feed inlet 4, ensuring that the material is evenly distributed and does not exceed the capacity limit of the mixing drum. Then, the motor 2 is started, and the motor 2 begins to run. Its output shaft drives the middle bevel gear 251 to rotate. This middle bevel gear 251 simultaneously drives the top and bottom bevel gears 251 to rotate in opposite directions. Specifically, after being driven by the middle bevel gear 251, the top bevel gear 251 begins to drive the connected rotating shaft 125 to rotate. The rotation of the rotating shaft 125 further drives the outer stirring paddle 127 to rotate. The outer stirring paddle 127 rotates at a certain speed inside the mixing drum 3, fully mixing and improving the uniformity of the material. At the same time, the bottom bevel gear 251 also begins to rotate under the drive of the middle bevel gear 251, driving the outer ring 126 to rotate in the opposite direction to the top. This design realizes bidirectional rotation inside the mixing drum 3, which not only improves the mixing efficiency but also... The materials are mixed more evenly during the mixing process, avoiding local accumulation or uneven mixing. However, after long-term use, some residue may accumulate inside the mixing drum 3 or maintenance may be required. At this time, the mixing drum 3 needs to be cleaned or maintained. To facilitate this operation, two pulling blocks are designed on the equipment. Simply pull these two pulling blocks outward, and they will drive the moving rod 116 outward. The movement of the moving rod 116 further drives the locking teeth 117 outward. When the locking teeth 117 move to a certain extent, they no longer lock the locking block 114 that originally cooperated with them. At this time, the handle 112 can be lifted upward. After the handle 112 is pulled upward, it begins to drive the cover 111 upward. The movement of the cover 111 not only moves it upward, but also drives the locking teeth 117 upward. When the cover 111 is pulled to the top and flipped backward, the opening of the mixing drum 3 is fully exposed. At this time, it is convenient to carry out maintenance and cleaning work inside the mixing drum 3.
