Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and in particular to a polymer composite material stirring and mixing device. Background Technology

[0002] With the widespread application of polymer composite materials in aerospace, automotive manufacturing, and new energy equipment, the requirements for material uniformity and performance stability are increasingly stringent. In the preparation process of polymer composite materials, the uniformity of raw material mixing directly affects the physical strength, heat resistance, and molding stability of the product. Therefore, developing a rationally structured and highly efficient mixing device has become an important direction for improving material performance and ensuring the quality of industrial production.

[0003] In existing technologies, fixed-blade stirring mechanisms are commonly used, with a single motor driving the stirring shaft to achieve the mixing function. Raw materials typically enter the stirring drum through a bottom feed inlet, and the stirring process is completed under the action of a vertical or horizontal stirring shaft. Some structures incorporate rotating impellers or propeller-shaped blades to increase stirring efficiency. However, most devices employ a single stirring motion and a fixed stirring path, which can easily lead to uneven mixing or localized sedimentation of the raw materials, and are not ideal for processing high-viscosity or multi-component materials.

[0004] However, a common problem in existing technologies is that after the raw materials enter the mixing tank, the stirring structure can only rotate around a single axis, lacking a multi-directional linkage stirring mechanism. This results in a limited circulation path for the raw materials during the stirring process, making it difficult to achieve thorough mixing. In particular, when processing high-viscosity polymer composite materials, the mixing efficiency is low, which in turn affects the overall practicality and adaptability of the device. Therefore, a polymer composite material stirring and mixing device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a polymer composite material stirring and mixing device, which aims to improve the problems of most devices having a single stirring motion mode and a fixed stirring path, which easily leads to uneven mixing or local deposition of raw materials, and unsatisfactory results when processing high viscosity or multi-component materials.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a polymer composite material stirring and mixing device, comprising a mixing tank, a sealing cover fixedly connected to the upper surface of the mixing tank, a plurality of feed pipes fixedly connected to the upper surface of the sealing cover, and a mixing component installed inside the mixing tank;

[0007] The mixing assembly includes a motor, the lower surface of which is fixedly connected to the upper surface of the sealing cover. A transmission rod is fixedly connected to the output end of the motor, and an auger blade is fixedly connected to the outer wall of the transmission rod. A transmission cylinder is fixedly connected to the bottom of the inner wall of the mixing tank. The transmission cylinder has symmetrical openings running through it. A connecting frame is fixedly connected to the upper side of the outer wall of the transmission rod, and a collar is fixedly connected to the lower surface of the connecting frame. A stirring blade is fixedly connected to the outer wall of the collar, and a stirring blade is fixedly connected to the inner wall of the mixing tank.

[0008] Furthermore, a fixing ring is fixedly connected to the outer wall of the mixing tank, and a connecting shaft is fixedly connected to the outer wall of the fixing ring.

[0009] Furthermore, a support plate is rotatably connected to the outer wall of the connecting shaft, and a gear is fixedly connected to the outer wall of the connecting shaft.

[0010] Furthermore, a base plate is fixedly connected to the lower surface of the support plate, a second motor is fixedly connected to the upper surface of the base plate, and an eccentric wheel is fixedly connected to the output end of the second motor.

[0011] Furthermore, a slide rail is fixedly connected to the outer wall of the support plate near the gear, and a rack plate is slidably connected to the outer wall of the slide rail, the rack plate meshing with the gear teeth.

[0012] Furthermore, a rotating plate is rotatably connected to one side of the outer wall of the rack plate, and one side of the rotating plate is rotatably connected to one side of the outer wall of the eccentric wheel.

[0013] Furthermore, a discharge pipe is fixedly connected to the lower surface of the mixing tank, and a valve is fixedly connected to the outer wall of the discharge pipe.

[0014] Furthermore, the outer wall of the auger blade is slidably connected to the inner wall of the transmission cylinder, the inner wall of the collar is rotatably connected to the outer wall of the transmission cylinder, and the first stirring blade and the second stirring blade are arranged alternately.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the motor drives the transmission rod to allow the raw material to enter the transmission cylinder through the lower opening, and then circulate and mix inside the mixing tank through the upper opening. The rotation of the transmission rod facilitates the rotation of the connecting frame. The rotation of the connecting frame then facilitates the rotation of the stirring blades on the outer wall of the collar. The cooperation between stirring blades one and two achieves efficient mixing of raw materials, thereby improving the practicality of the device.

[0017] 2. In this utility model, the eccentric wheel is driven to rotate by the second motor, and then the rotating plate is driven to rotate by the eccentric wheel. At this time, the rotating plate drives the rack plate to slide on the outer wall of the slide rail. Then, the rack plate meshes with the gear to rotate, thereby facilitating the rotation of the connecting shaft inside the support plate. The rotation of the connecting shaft facilitates the reciprocating swing of the mixing barrel inside the fixed ring. Through the movement of the mixing barrel, the material is easily discharged while the mixing barrel further mixes the raw materials, thus improving the practicality of the device.

A second stirring blade 12 is fixedly connected to the inner wall of the mixing tank 1, which acts as a directional turbulence structure to improve the uniformity of mixing.

[0026] Specifically, through the conveying function of the auger blade 6 and the coordinated stirring of the first stirring blade 11 and the second stirring blade 12, the raw materials are circulated up and down and stirred in multiple directions within the mixing tank 1, thereby improving mixing efficiency and uniformity.

A gear 18 is fixedly connected to the outer wall of the connecting shaft 16. The gear 18 meshes with the rack plate 23 to transmit rotational power to... The linear motion conversion is as follows: A base plate 19 is fixedly connected to the lower surface of the support plate 17, which provides an installation platform for the second motor 20 and enhances the structural rigidity; the second motor 20 is fixedly connected to the upper surface of the base plate 19, which provides reciprocating drive power for this structure; an eccentric wheel 21 is fixedly connected to the output end of the second motor 20, which can convert the rotational motion into irregular reciprocating motion to drive the downstream rotating plate 22 to perform periodic motion; a slide rail 24 is fixedly connected to the outer wall of the support plate 17 near the gear 18, which is used to limit the rack plate 23.

The feed pipe 13 is used to discharge the mixed material; a valve 14 is fixedly connected to the outer wall of the discharge pipe 13, which is used to control the opening and closing of the discharge pipe 13 to achieve discharge control; the outer wall of the auger blade 6 is slidably connected to the inner wall of the transmission cylinder 7, so that it can slide axially in the transmission cylinder 7 and transport raw materials; the inner wall of the collar 10 is rotatably connected to the outer wall of the transmission cylinder 7 to achieve rotational freedom, which is conducive to the rotation of the stirring blade 11; the stirring blade 11 and the stirring blade 2 12 are staggered, and the staggered structure can enhance the disturbance of raw materials and improve the mixing uniformity.

[0028] Specifically, the intermittent dynamic adjustment of the mixing system is achieved through the linkage mechanism of the rack and pinion 18 driven by the motor 20 and the eccentric wheel 21. Combined with the coordinated operation of the discharge structure and the mixing components, the control precision and operational flexibility of the device in the raw material mixing and discharge process are enhanced, effectively improving the mixing efficiency and the quality of the finished product.

[0029] Working principle: When this mixing device is needed to mix polymer composite materials, different raw materials are first put into the mixing tank 1 through the feed pipe 3. Then, the motor 4 drives the transmission rod 5 to rotate. The transmission rod 5 then drives the auger blade 6 to transfer the raw materials into the transmission cylinder 7 through the lower opening 8. Then, the auger blade 6 transfers the raw materials back into the mixing tank 1 through the upper opening 8 of the transmission cylinder 7, thus achieving a circulating mixing effect. The rotation of the transmission rod 5 causes the connecting frame 9 to drive the outer stirring blade 11 of the collar 10 to rotate. The mixing blade 11 and the stirring blade 12 are then coordinated. The mixing process achieves efficient and uniform mixing. Then, the starting motor 20 drives the eccentric wheel 21 to rotate, which in turn drives the rotating plate 22 to rotate. The rotating plate 22 then drives the rack plate 23 to mesh with the gear 18 and rotate. The rack plate 23 slides on the outer wall of the slide rail 24, achieving a limited sliding effect. The gear 18 then drives the fixing ring 15 on one side of the connecting shaft 16 to reciprocate. The shaking of the mixing drum 1 further enhances the efficient mixing of raw materials. Simultaneously, the gear 18 can tilt the mixing drum 1, opening the valve 14 to discharge the mixed raw materials for use.
