[0037] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0038] This embodiment relates to a foam raw material stirring device. The overall structure includes a stirring barrel 1 and a stirring mechanism disposed within the stirring barrel 1. A feeding port is provided at the top of the stirring barrel 1, and a discharge pipe 1021 is provided at the bottom of the stirring barrel 1. The stirring mechanism includes a first rotating roller 2 disposed in the center of the stirring barrel 1, a plurality of first stirring blades 201 disposed on the first rotating roller 2, and a plurality of stirring rods 3 rotating around the first rotating roller 2. A first sleeve 301 is rotatably disposed at the upper end of the first rotating roller 2. The first sleeve 301 extends radially to form a first connecting arm 302 connecting each stirring rod 3.

[0039] As described above, through the arrangement of the first stirring blade 201 on the roller and the stirring rod 3, the roller drives the first stirring blade 201 to stir the raw materials in the stirring barrel 1. At the same time, the stirring rod 3 surrounds the roller, thereby expanding the stirring range of the raw materials and enabling convection to form inside the raw materials, thereby improving the stirring effect and stirring efficiency of the raw materials.

[0040] Based on the above overall introduction, specifically, in this embodiment, two stirring rods 3 are configured. Of course, in order to improve the stirring effect, other numbers of stirring rods 3 can also be provided. In this embodiment, the lower end of the first roller 2 is provided with a first spiral blade 202. At least a portion of the first spiral blade 202 extends into the discharge pipe 1021, and the edge of the first spiral blade 202 is in contact with the wall of the discharge pipe 1021. In a specific implementation, when the first roller 2 rotates forward, the first spiral blade 202 can push the raw materials located at the discharge pipe 1021 toward the mixing barrel 1 above. When the first roller 2 rotates backward, the first spiral blade 202 can transport the raw materials in the mixing barrel 1 into the discharge pipe 1021.

[0041] Thus, the first spiral blade 202 can transport the raw materials at the bottom of the mixing barrel 1 upward during the mixing process, forming a bottom-to-top convection flow, thereby preventing some of the raw materials from settling at the bottom and not being fully mixed, thereby improving the mixing effect. At the same time, it prevents unmixed raw materials from flowing out of the discharge pipe 1021. When the mixing is completed and the materials need to be discharged, the first spiral blade 202 can discharge the mixed raw materials.

[0042] In this embodiment, the mixing barrel 1 includes a cylindrical upper barrel 101 and a funnel-shaped lower barrel 102. The stirring rods 3 are located in the upper barrel 101, and the first spiral blade 202 is located in the lower barrel 102. The funnel-shaped lower barrel 102 facilitates the flow of raw materials into the discharge pipe 1021, thereby preventing raw materials from remaining in the mixing barrel 1 to a certain extent. In addition, in this embodiment, a feeding funnel 1011 is provided at the feeding port to facilitate the feeding of raw materials into the mixing barrel 1.

[0043] As a specific implementation form, the first stirring blades 201 of this embodiment surround the first roller 2 and are spaced apart along the length direction of the first roller. A plurality of second stirring blades 303 are provided on the outer circumference of the stirring rod 3, and the second stirring blades 303 and the first stirring blades 201 are staggered in the length direction of the first roller 2. By providing the first stirring blades 201 and the second stirring blades 303, the stirring area of ​​the stirring mechanism for the raw materials in the stirring barrel 1 is further increased to improve the stirring effect. At the same time, the staggered arrangement of the first stirring blades 201 and the second stirring blades 303 enables the stirring blades to shear the raw materials to prevent the raw materials from agglomerating.

[0044] In addition, a plurality of third stirring blades 1012 are provided on the inner wall of the mixing barrel 1, and the third stirring blades 1012 and the second stirring blades 303 are staggered in the length direction of the first roller 2, so that the raw materials between the mixing barrel 1 and the stirring rod 3 can also be fully stirred and the agglomeration of the raw materials can be reduced.

[0045] In this embodiment, the direction in which the stirring rod 3 surrounds the first roller 2 is opposite to the rotation direction of the first roller 2, that is, the first sleeve 301 is opposite to the rotation direction of the roller, so that there is a higher relative speed between the first stirring blade 201 and the second stirring blade 303, thereby further increasing the effect of the stirring blade on breaking up the agglomerated raw materials.

[0046] Specifically, the top of the mixing barrel 1 of this embodiment is provided with a transmission mechanism 4, which includes a coaxially arranged first bevel gear 401 and a second bevel gear 402, a third bevel gear 403 meshing with the first bevel gear 401 and the second bevel gear 402, and a housing 404. The first bevel gear 401 is connected to the first roller 2, and the second bevel gear 402 is connected to the first sleeve 301. The third bevel gear 403 is rotatably connected to the side wall of the housing 404. A first motor 5 is provided on the outside of the top of the mixing barrel 1, and the output shaft of the first motor 5 is connected to the first bevel gear 401. Due to the configuration of the transmission mechanism 4, when the first bevel gear 401 is driven to rotate by the first motor 5, the second bevel gear 402 can drive the first sleeve 301 to rotate in a direction opposite to the rotation direction of the first roller 2.

[0047] Furthermore, the multiple blades on the stirring rod 3 create significant resistance when the stirring rod 3 wraps around the first roller 2, and during rotation, the stirring rod 3 is susceptible to radially outward distortion. Therefore, to enhance the structural strength of the stirring rod 3, a second connecting arm 304 extending toward the first roller 2 is formed at the bottom end of each stirring rod 3 in this embodiment, and a second sleeve 305 is rotatably mounted on the first roller 2. The second sleeve 305 and second connecting arm 304 constrain the bottom end of the stirring rod 3, preventing deformation and improving the overall reliability of the stirring mechanism.

[0048] As a specific implementation form, this embodiment also includes a conveying device, which includes a second roller 7 connected to a conveying channel 6, disposed within the conveying channel 6, and a second spiral blade 701 disposed on the second roller 7. The conveying channel 6 is arranged horizontally and communicates with the discharge pipe 1021. One end of the conveying channel 6 is closed, and the other end forms a discharge port. A second motor 601 is disposed outside the conveying channel 6 to drive the second roller 7 to rotate. The arrangement of the conveying device allows the raw materials to be transported horizontally from the bottom of the mixing barrel 1 to one side of the mixing barrel 1, facilitating the acquisition of the raw materials. The arrangement of the conveying device also facilitates the transport of the raw materials to the next production equipment.

[0049] Furthermore, in this embodiment, a plurality of stirring rods 602 are provided on the sidewalls of the conveying channel 6, and a plurality of second spiral blades 701 are arranged at intervals along the length of the second roller 7. When the second roller 7 rotates, each stirring rod 602 can pass through the gap between two adjacent spiral blades, preventing interference between the stirring rods 602 and the second spiral blades 701. The arrangement of the plurality of second spiral blades 701 and stirring rods 602 allows the raw materials to be further stirred and mixed by the stirring rods 602 while being conveyed by the second spiral blades 701, thereby further enhancing the stirring effect to a certain extent.

[0050] In summary, the foam raw material stirring device of this embodiment, through the setting of the first stirring blade 201 on the roller and the stirring rod 3, the roller drives the first stirring blade 201 to stir the raw materials in the stirring barrel 1, and at the same time the stirring rod 3 surrounds the roller, thereby expanding the stirring range of the raw materials and enabling convection to form inside the raw materials, thereby improving the stirring effect and stirring efficiency of the raw materials, and has good practicality.

[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 replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
