Description

Technical Field

[0001] The utility model relates to the technical field of talc masterbatch production equipment, in particular to a raw material stirring device for talc masterbatch production. Background Art

[0002] The production process of talc masterbatch includes feeding, mixing, melting (also known as plasticizing), granulation, and cooling. Melting involves feeding the mixed raw materials into a melting and stirring device, controlling the temperature to melt them, and then gradually cooling them naturally to form a paste. Constant stirring is required throughout this process.

[0003] During melting, the uniformity of raw material mixing and the uniformity of viscosity after the melt cools to form a paste are both crucial, impacting the quality of subsequent granulation. Existing mixing methods primarily rely on unidirectional stirring with a stirring blade. Since talc masterbatch raw materials have a certain viscosity after transitioning from a molten state to a paste, the material, once reaching a certain viscosity, will move in the direction of the stirring blade, preventing further improvement in both uniformity and viscosity. Utility Model Content

[0004] In response to the above-mentioned shortcomings of the prior art, the utility model provides a raw material stirring device for the production of talcum powder masterbatch, which stirs the raw materials in multiple directions through a pair of stirring blades arranged crosswise in the stirring paths, thereby preventing the viscous paste raw materials from following the unidirectional rotation of the stirring blades, thereby making the stirring more uniform and the viscosity more uniform.

The center position of the bottom of the box is rotatably connected to the bottom plate through the rotating support. One end of the cylinder is rotatably connected to the side of the bottom of the box away from the material port, and the other end is rotatably connected to the bottom plate. The extension of the telescopic end of the cylinder can enable the box to rotate around the center of the rotating support.

[0017] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1-3 As shown, a raw material stirring device for producing talcum powder masterbatch comprises a base plate 1, a box body 6, a heating mechanism 9 and a turning mechanism, the box body 6 is arranged on the base plate 1 through the turning mechanism, and the turning mechanism can drive the box body 6 to turn 90 degrees-180 degrees, a material port 7 is provided on the upper surface of the box body 6 near one side edge position, the heating mechanism 9 is arranged on the inner side wall of the box body 6, and stirring blades are respectively provided on the front and rear side walls of the box body 6 for rotation; the stirring blade connected to the front side wall of the box body 6 is a first stirring blade 4, and a first motor 11 is arranged on the outside of the front side wall of the box body 6, and the output end of the first motor 11 passes through the box body 6 and is fixedly connected to the center position of the first stirring blade 4; the stirring blade connected to the rear side wall of the box body 6 is a second stirring blade 5, and a second motor 12 is arranged on the outside of the rear side wall of the box body 6, and the output end of the second motor 12 passes through the box body 6 and is fixedly connected to the center position of the second stirring blade 5; the first motor 11 and the second motor 12 rotate clockwise or counterclockwise at the same time. The two ends of the gear train 2 are connected with each other, and the two ends of the gear train 2 are connected with each other, and the gear train 2 is turned by the help of the support 2 so that the gears 2 can be turned around and rotated.

[0019] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0020] According to the instruction manual Figure 1-3It can be seen that when the utility model is working, the raw material mixture of talcum powder masterbatch is put into the material port 7 of the box body 6, and the first motor 11 and the second motor 12 and the heating mechanism 9 are started. The heating mechanism 9 here can be made of existing technology, which can make the talcum powder masterbatch raw material into a molten state, and finally cool it naturally. During this period, it is stirred all the time, and the raw material will gradually turn from a molten state to a paste. During the stirring operation, the first motor 11 and the second motor 12 rotate to drive the first stirring blade 4 and the second stirring blade 5 to rotate respectively. The first motor 11 and the second motor 12 rotate clockwise or counterclockwise at the same speed. Here, it is assumed that they rotate counterclockwise uniformly. Because in the design, the positions of the first stirring blade 4 and the second stirring blade 5 make their stirring paths intersect and satisfy that the two stirring blades will not collide during the movement. No collision means that the two stirring blades are in a separated state during the movement, such as Figure 3 As shown, the U-shaped plane of the first stirring blade 4 and the second stirring blade 5 is in a vertical state, and the two will not collide and contact during the motion. When stirring, this design mode can intercept the sticky pasty material that the second stirring blade 5 stirs and drives, and in the same way, the second stirring blade 5 can also intercept the sticky pasty material that the first stirring blade 4 stirs and drives, so as to achieve the purpose of cross-stirring, avoid the sticky pasty material from following the stirring blade unidirectional rotation all the time, so that it is stirred more evenly, and viscosity is more even. Of course, the stirring blade in the utility model can also be the solid raw material and the molten state raw material that have just been added to stir. After the whole stirring is completed, the casing 6 is turned over by the turnover mechanism at 90 degrees to 180 degrees, and the mixed raw material that has been stirred can be sent to the granulator for granulation.

[0021] The flipping mechanism includes a cylinder 3 and a rotating support 2. The bottom center of the box 6 is rotatably connected to the base plate 1 via the rotating support 2. One end of the cylinder 3 is rotatably connected to the side of the bottom of the box 6 away from the material inlet 7, and the other end is rotatably connected to the base plate 1. Extending the telescopic end of the cylinder 3 enables the box 6 to rotate about the center of the rotating support 2. The raw material can be poured out of the material inlet 7 by rotating the box 6 90-180 degrees. The rotating support 2 can be connected to the box 6 and the base plate 1 respectively using the existing shaft and shaft seat. The overall flipping mechanism is simple in structure, easy to use, and easy to repair and maintain.

[0022] The first stirring blade 4 is provided with a slider 14 on the side of the housing 6 corresponding to the side wall. A circle of slide grooves 13 are provided on the side wall of the housing 6 corresponding to the slider 14, centered at the output end of the first motor 11. The slider 14 is slidably connected to the slide grooves 13. The second stirring blade 5 is provided with the same design as the first stirring blade 4 between the side wall of the housing 6. The above design can ensure the stability of the stirring blade's rotation, thereby improving the stirring effect.

[0023] A cover plate 10 is rotatably provided on the box body 6 at a position corresponding to the material port 7 . Closing the cover plate 10 reduces heat loss during melting of the raw materials in the box body 6 , while opening the cover plate 10 accelerates natural cooling.

[0024] Among them, the interior of the box body 6 is designed to be an arc shape 8 similar to the movement trajectory of the stirring blade. On the one hand, it ensures a larger stirring space occupancy during stirring and improves the stirring effect. On the other hand, it is convenient to pour out the final paste raw materials.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
