Description

Technical Field

[0001] The utility model belongs to the technical field of stirring equipment, in particular to a forward and reverse stirring device for producing PA66 composite materials. Background Art

[0002] The production process of PA66 composite materials requires the use of agitators to stir the materials. However, existing agitators are mostly unidirectional. When handling viscous materials or mixtures with large particles, unidirectional agitators can easily cause the materials to form dead corners or accumulate within the barrel, preventing adequate mixing. This often leads to poor contact between the material and the agitator, resulting in uneven mixing and affecting the quality of the final product. Furthermore, the unidirectional design limits the agitator's efficiency. Especially in processes requiring high stirring intensity, the single direction of rotation cannot effectively break down the material layers, resulting in longer stirring times and lowering overall production efficiency.

[0003] Conventional approaches to address these issues include increasing the stirring speed and extending the stirring time. However, each of these approaches has its drawbacks. While increasing the stirring speed can improve mixing efficiency to a certain extent, it can also lead to increased energy consumption and accelerated equipment wear, shortening service life. Extending the stirring time directly extends the production cycle, reduces overall production capacity, and increases production costs. Therefore, we sought to design a stirring device with a novel structure to address this issue. Utility Model Content

[0039] The stirring member 330 includes a transmission gear 331, a connecting frame 332, a bevel gear 333, and a stirring plate 334. The transmission gear 331 and the bevel gear 333 are integrally mounted on the upper side of the fixed shaft 370 through the shaft sleeve.

[0040] A connecting frame 332 is welded to the middle outer wall of the sleeve, and five equally spaced arm rods 1 are extended outward from the connecting frame 332, and a stirring plate 334 is welded to the lower end of each arm rod.

[0041] The transmission member 350 includes a bevel gear 1 333, a bevel gear 2 351 and a fixed rod 352. The fixed rod 352 crosses the lower end of the fixed shaft 370 and is fixed thereto.

[0044] As a second embodiment of the present invention, based on the above-mentioned first embodiment, the adjusting component 200 cooperates with the stirring component 300. When the material is added or the stirring is completed, the cantilever 310 can be driven upward by rotating the screw rod 220 on the stand 210 (in actual use, a motor is installed on the upper side of the stand 210, and the screw rod 220 is driven to rotate by a transmission pulley, which is not drawn in the figure and can be set according to actual use requirements, as long as the use requirements are met), so that it is separated from the stirring drum 140, which is convenient for cleaning the stirring drum 140 and the stirring component 300. When stirring is needed, the cantilever 310 can be moved upward again by the screw rod 220 The cantilever 310 is lowered and the stirring element 1 330 and the stirring element 2 360 are placed into the mixing drum 140. During stirring, the stirring motor installed on the cantilever 310 is started to drive the connecting rod mechanism 320. The rotating shaft 321 drives the transmission rod 322 to rotate, which cooperates with the limiting frame 340 to drive the rack 323 to reciprocate. The reciprocating motion of the rack 323 continuously drives the transmission gear 331 on the upper side of the stirring element 1 330 to rotate. The transmission gear 331 drives the bevel gear 1 333 on the lower side of the shaft sleeve to rotate, thereby rotating the connecting frame 1 332 welded to the shaft sleeve and the multiple stirring plates 1 334 thereon.

[0045] At the same time, the bevel gear 1 333 synchronously drives the bevel gear 2 351 and the bevel gear 3 353 installed at both ends of the fixed rod 352, and synchronously drives the bevel gear 4 361 through the bevel gear 2 351 and the bevel gear 3 353. The bevel gear 4 361 rotates synchronously with the bevel gear 1 333 in the opposite direction under the drive of the bevel gear 2 351 and the bevel gear 3 353, driving the connecting frame 2 362 fixed on its lower side and the stirring plate 2 363 thereon. The connecting frame 2 362, the stirring plate 2 363 and the connecting frame 1 332 and the stirring plate 363 are connected. The rotation direction of mixing plate 1 334 is opposite. Since the length of arm 1 is greater than one and a half times the length of arm 2, the length and width of mixing plate 1 334 are greater than the length and width of mixing plate 2 363. This allows the stirring element 1 330 to rotate forward and reversely inside and outside the mixing drum 140, while the stirring element 2 360 to rotate forward and reversely in the middle of the mixing drum 140. This can avoid the problem of dead corners or accumulation of materials in the barrel body caused by single unidirectional stirring, and help to expand the stirring effect of the entire stirring assembly 300.

[0046] 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.
