Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, and more specifically to a stirring device for preheating impregnated resin. Background Technology

[0002] Impregnating resin is a functional resin that adsorbs liquid extractants or impregnates reinforcing materials through cross-linked copolymer carriers. Its functions and composition vary depending on the application, and its functions include insulation, moisture protection, vibration resistance, and high temperature resistance.

[0003] During the preparation of impregnating resin, it is often necessary to stir it to improve the contact efficiency between the resin and additives such as curing agents and diluents, thereby shortening the mixing time of the fused resin. However, during the stirring process of impregnating resin, stirring blades are often set on the stirring rod and the bottom of the stirring blades is placed at the bottom of the stirring tank. Due to the different content of the added raw materials and the fixed position of the stirring blades, only the stirring speed can be adjusted to promote the eddy mixing effect. When the content of the added raw materials is too large, the speed of the stirring blades is too fast, which will introduce a large number of air bubbles. The air bubbles will form stress concentration points, resulting in a reduction in the production quality of the resin. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies, specifically to solve the issue that during resin mixing, factors such as placing the mixing blades at the bottom of the mixing tank, excessive raw material quantity, and high mixing speed can easily lead to air bubbles forming during resin mixing, thereby affecting the quality of resin production.

[0005] To achieve the above objectives, this utility model can be implemented through the following technical solution: a stirring device for preheating impregnated resin, comprising: A mixing tank, wherein a cover plate is provided on the mixing tank, and the mixing tank and the cover plate are closed to form a mixing chamber; A stirring unit is disposed on the cover plate.

[0006] In this embodiment of the utility model, the stirring rack includes a support sleeve, a first connecting rod, and a second connecting rod. The support sleeve is rotatably connected to the first connecting rod and the second connecting rod, and the first connecting rod and the second connecting rod are rotatably connected. The support sleeve slides on the rotating shaft and is rotatably connected to the adjusting ring.

[0010] In this embodiment of the utility model, the sleeve is provided with blades arranged in a circumferential array, and the blades are provided with stirring holes.

[0011] In this embodiment of the utility model, the rotating shaft is provided with a threaded groove and a guide groove, the adjusting ring is threadedly connected to the threaded groove, and the stirring frame is slidably connected to the guide groove.

[0012] In this embodiment of the utility model, the mixing tank is provided with an outer shell, and heating rings are arranged in a linear array between the mixing tank and the outer shell. A temperature controller electrically connected to the heating rings is provided on the outer shell.

[0018] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0019] like Figure 1-4 As shown, a stirring device for preheating impregnated resin includes: A mixing tank 1 is provided with a cover plate 3, and the mixing tank 1 and the cover plate 3 are closed to form a mixing chamber. The stirring unit 4 is mounted on the cover plate 3. The stirring unit 4 includes an adjusting ring 433, a motor 41, and a rotating shaft 43 located at the output end of the motor 41. Stirring racks 44 are arranged in a linear array on the rotating shaft 43. The adjusting ring 433 is threadedly connected to the rotating shaft 43. A stirring element 45 is provided between the two stirring racks 44. The adjusting ring 433 rotates to control the stirring rack 44 to move up or down along the axis of the rotating shaft 43, so as to adjust the relative position of the stirring element 45 in the stirring chamber.

[0020] Specifically, the mixing tank 1 is preheated by heating ring 22 to ensure that the temperature inside the mixing tank 1 is maintained at the preheated temperature. Then, the resin raw material is poured into the mixing chamber along the feeding end 13. The resin raw material gradually melts at the preheated temperature. At this time, motor 41 runs to drive the rotating shaft 43 and the stirring frame 44 to rotate synchronously. Through the rotation and stirring action of the stirring frame 44 and the stirring element 45, the resin raw material is cut and the mixing effect of the resin raw material is improved. When different contents of resin are added into the mixing chamber, the liquid level is also relatively different. At this time, the adjusting ring 433 can be rotated to make the two stirring frames 44 move up or down along the central axis of the rotating shaft 43 so that the stirring element 45 is located at the center of the liquid level, thereby promoting and improving the mixing effect of the resin raw material.

[0021] As a further embodiment of this utility model, the stirring frame 44 includes a support sleeve 444, a first connecting rod 441, and a second connecting rod 442. The support sleeve 444 is rotatably connected to the first connecting rod 441 and the second connecting rod 442, and the first connecting rod 441 and the second connecting rod 442 are rotatably connected. The support sleeve 444 slides on the rotating shaft 43 and is rotatably connected to the adjusting ring 433. When the adjusting ring 433 rotates upward, the support sleeve 444 drives the first connecting rod 441 and the second connecting rod 442 to move upward synchronously. The connection point of the first connecting rod 441 and the second connecting rod 442 becomes narrower, thereby adjusting the relative position of the stirring element 45 so that the stirring element 45 is located at the center of the resin raw material for stirring. Furthermore, the support sleeve 444 in the bottom stirring frame 44 is fixed to the rotating shaft 43 by bolts, and its support sleeve 444 is a fixed element.

[0022] As a further embodiment of this utility model, a fixing rod 445 is provided between the two stirring racks 44, and the two stirring racks 44 can slide up or down synchronously through the fixing rod 445. At least two sets of fixing rods 445 are provided.

[0023] As a further embodiment of this utility model, square grooves 443 are provided on both the first connecting rod 441 and the second connecting rod 442. During the rotation of the stirring frame 44, the first connecting rod 441 and the second connecting rod 442 will rotate inside the resin raw material to stir the resin raw material. At this time, the square grooves 443 improve the contact effect between the stirring frame 44 and the resin raw material, and further promote the mixing of the resin raw material.

[0024] As a further embodiment of this utility model, the stirring component 45 includes a rotating seat 455, a sleeve 450, and a support rod 452 slidably disposed within the sleeve 450. The support rod 452 is connected to the stirring frame 44 via the rotating seat 455. A spring 451 is provided between the support rod 452 and the sleeve 450. The spring 451 is used to pull back to support the sleeve 450 to the center of the resin raw material. A sealing ring is provided between the support rod 452 and the sleeve 450. The sleeve 450 and the support ring can only slide along the axis and cannot rotate synchronously.

[0025] As a further embodiment of this utility model, the sleeve 450 is provided with blades 453 arranged in a circumferential array, and the blades 453 are provided with stirring holes 454. Multiple sets of blades 453 are evenly distributed in a ring around the central axis of the sleeve 450. When the stirring frame 44 rotates, the resin raw material is cut by the blades 453 and stirring holes 454, thereby improving the mixing effect of the resin raw material.

[0026] As a further embodiment provided by this utility model, the rotating shaft 43 is provided with a threaded groove 431 and a guide groove 432 respectively. The adjusting ring 433 is threadedly connected to the threaded groove 431, while the stirring frame 44 is slidably connected to the guide groove 432. The support sleeve 444 in the stirring frame 44 is slidably connected to the guide groove 432, but the support sleeve 444 does not contact the threaded groove 431. The stirring frame 44 can only slide along the groove, while the adjusting ring 433 rotates on the threaded groove 431, thereby adjusting the stirring frame 44.

[0027] As a further embodiment of this utility model, a shell 2 is provided on the mixing tank 1, and heating rings 22 are arranged in a linear array between the mixing tank 1 and the shell 2. A temperature controller 21 electrically connected to the heating rings 22 is provided on the shell 2. The heating rings 22 are heated by the temperature controller 21, and each temperature controller 21 controls the corresponding heating ring 22. When different amounts of resin raw materials are added to the mixing tank 1, the heating effect on the resin raw materials is improved by opening the heating rings 22 that are in contact with the resin raw materials.

[0028] As a further embodiment of this utility model, the mixing tank 1 is provided with an arc-shaped protrusion 11, and the heating ring 22 is engaged with the arc-shaped protrusion 11. When the heating ring 22 is heated, the resin raw material will melt accordingly. The arc-shaped protrusion 11 reduces the resin raw material adsorbed onto the inner wall of the mixing chamber and improves the falling effect of the resin raw material.

[0029] As a further embodiment of this utility model, a guide plate 12 is provided at the bottom of the mixing tank 1. The guide plate 12 increases the flow rate of the resin raw material from the discharge end 13 after mixing. A feeding end 32 is provided on the cover, and a discharge end 13 corresponding to the feeding end 32 is provided on the mixing tank 1 to promote the feeding and discharge effect of the mixing tank 1. At the same time, a circular bracket 31 is provided on the cover plate 3. The circular bracket 31 supports the motor 41, and the motor 41 controls the rotation of the shaft 43 through the coupling 42.
