Description

Technical Field

[0001] This utility model belongs to the field of epoxy resin processing technology, and in particular relates to a bubble elimination device for epoxy resin processing. Background Technology

[0002] Epoxy resins are widely used in aerospace, electronics, construction, automobile manufacturing, wind turbine blades, and sporting goods due to their excellent mechanical properties, chemical resistance, adhesive properties, and electrical insulation properties. However, during the processing of epoxy resins, especially in operations such as mixing, pouring, and coating of liquid resins, air bubbles are often introduced.

[0003] The presence of air bubbles reduces the density of materials, leading to a significant decrease in their mechanical properties (such as tensile strength, compressive strength, and impact toughness). Furthermore, epoxy resins are commonly used as insulating materials in the electronics and electrical appliance industries; the presence of air bubbles creates conductive channels, reducing the material's electrical insulation performance and increasing the risk of leakage and breakdown. Current methods for removing air bubbles generally involve stirring the resin, i.e., using mechanical agitation to cause the bubbles to aggregate and escape. While this method is simple and easy to implement, it is difficult to completely eliminate tiny air bubbles, and new air bubbles may be introduced during the stirring process.

[0004] To address these issues, we provide an epoxy resin processing bubble elimination device. Utility Model Content

[0005] The purpose of this invention is to provide a bubble elimination device for epoxy resin processing. Through the action of the processing plate, the adjusting shell drives the connecting rods on both sides and the processing plate to move slowly within the processing chamber, stirring the epoxy resin. This causes the bubbles within the epoxy resin to gather and escape. Simultaneously, a vacuum pump is activated to evacuate the air inside the processing chamber, accelerating the removal of bubbles. This significantly improves the bubble elimination efficiency of the device, solving the problem that existing methods for removing bubbles generally involve stirring the resin, i.e., mechanically stirring to cause bubbles to gather and escape. While this method is simple and easy to implement, it is difficult to completely eliminate tiny bubbles, and new bubbles may be introduced during the stirring process.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a bubble elimination device for epoxy resin processing, including a processing box, and a box cover is fixed on the top of the processing box;

[0007] A positioning shell is fixed to the top of the box cover, and a motor is fixed to the top of the positioning shell;

[0008] The motor output shaft passes through the positioning housing;

[0009] A limiting plate is fixed to the bottom of the box cover, and an adjusting shell is slidably connected inside the limiting plate;

[0010] The first engagement block is fixed on both sides of the inner wall of the regulating shell, and the transmission block is fixed on the motor output shaft;

[0011] The transmission block is uniformly fixed with a second meshing block within a 180° range on its outer ring, and the first meshing block and the second meshing block are meshed and connected.

[0012] Both sides of the adjusting shell are fixed with support plates, and a connecting rod is fixed to the outside of the support plate. A processing plate is fixed to one end of the connecting rod.

[0013] The surface of the processing plate has several through grooves.

[0014] The present invention is further configured such that: the limiting plate has an "L" shaped structure, and the inner wall of the limiting plate is slidably connected to the support plate.

[0015] The present invention is further configured such that: a sliding groove is fixed to the inner wall of the limiting plate, and sliding strips are fixed to both sides of the supporting plate;

[0016] The slider is slidably connected to the slide groove.

[0017] The present invention is further configured such that: an exhaust pipe is fixed to the top of the box cover, and a vacuum pump is fixed to one end of the exhaust pipe.

[0018] The present invention is further configured such that: the outer ring of the connecting rod has a threaded groove, and the outer ring of the threaded groove is threadedly connected to a threaded pipe;

[0019] The outer ring of the threaded tube is fixed with a bearing.

[0020] The present invention is further configured such that: an adjusting plate is fixed to the outer ring of the bearing, and a telescopic rod is fixed between the adjusting plate and the housing cover.

[0021] The present invention is further configured such that: the surface of the adjusting plate has several through holes, and the bottom of the adjusting plate is fixed with several conical blocks.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model utilizes the action of the processing plate, which in turn causes the adjusting shell to slowly move the connecting rods on both sides and the processing plate within the processing box, stirring the epoxy resin. This causes the air bubbles in the epoxy resin to gather and escape. Simultaneously, the vacuum pump is turned on to evacuate the air inside the processing box, accelerating the removal of air bubbles and thus greatly improving the bubble elimination efficiency of the device.

[0024] 2. This utility model utilizes the action of the conical block. When the conical block at the bottom of the adjusting plate comes into contact with the surface of the epoxy resin, during the stirring process, bubbles accumulate and overflow within the epoxy resin. The conical block then punctures the bubbles floating on the surface, accelerating their rupture and allowing the epoxy resin in the processing chamber to quickly expel the bubbles from its interior.

Specific Implementation Example 1

[0038] Please see Figure 1-6 This utility model is a bubble elimination device for epoxy resin processing, including a processing box 1, a box cover 2 fixed to the top of the processing box 1; a positioning shell 3 fixed to the top of the box cover 2, and a motor 4 fixed to the top of the positioning shell 3; the output shaft of the motor 4 passes through the positioning shell 3; a limit plate 5 fixed to the bottom of the box cover 2, and an adjusting shell 6 slidably connected inside the limit plate 5; a first meshing block 7 fixed to both sides of the inner wall of the adjusting shell 6, and a transmission block 8 fixed to the output shaft of the motor 4; a second meshing block 9 evenly fixed within a 180° range on the outer ring of the transmission block 8, and the first meshing block 7 and the second meshing block 9 meshing and connected; a support plate 10 fixed to both sides of the adjusting shell 6, a connecting rod 11 fixed to the outer side of the support plate 10, and a processing plate 12 fixed to one end of the connecting rod 11; and several through grooves 13 opened on the surface of the processing plate 12.

[0039] Specifically, the limiting plate 5 has an "L" shaped structure, and the inner wall of the limiting plate 5 is slidably connected to the support plate 10.

[0040] Furthermore, a sliding groove 14 is fixed to the inner wall of the limiting plate 5, and sliding strips 15 are fixed to both sides of the support plate 10; the sliding strips 15 are slidably connected to the sliding groove 14; an exhaust pipe 16 is fixed to the top of the box cover 2, and a vacuum pump 17 is fixed to one end of the exhaust pipe 16.

[0041] The operation process of this embodiment is as follows: When the device is in use, the motor 4 is turned on, and the output shaft of the motor 4 drives the transmission block 8 at one end to rotate. When the transmission block 8 rotates, the second meshing block 9 on its outer side drives the first meshing block 7 inside the adjusting shell 6 to move through the meshing connection. When the smooth surface of the transmission block 8 contacts the first meshing block 7 on one side, the second meshing block 9 meshes with the first meshing block 7 on the other side, thereby pushing the adjusting shell 6 left and right. The adjusting shell 6 then drives the connecting rods 11 and the processing plate 12 on both sides to move slowly in the processing box 1 to stir the epoxy resin, thereby causing the bubbles in the epoxy resin to gather and escape. At the same time, the vacuum pump 17 is turned on to evacuate the air in the processing box 1, accelerating the discharge of bubbles, thereby greatly improving the bubble elimination efficiency of the device. Specific Implementation Example 2

[0043] Please see Figure 6 Based on the first specific embodiment, the outer ring of the connecting rod 11 has a threaded groove 18, and the outer ring of the threaded groove 18 is threadedly connected to a threaded tube 19.

[0044] The outer ring of the threaded pipe 19 is fixed with a bearing 20.

[0045] Specifically, an adjusting plate 21 is fixed to the outer ring of the bearing 20, and a telescopic rod 22 is fixed between the adjusting plate 21 and the cover 2.

[0046] Furthermore, the surface of the adjusting plate 21 has several through holes 23, and several conical blocks 24 are fixed to the bottom of the adjusting plate 21.

[0047] The operation process of this embodiment is as follows: When in use, the position of the adjusting plate 21 can be adjusted according to the amount of epoxy resin, that is, rotate the threaded tube 19 so that the threaded tube 19 moves on the threaded groove 18, which drives the adjusting plate 21 to move. When the conical block 24 at the bottom of the adjusting plate 21 contacts the liquid surface of the epoxy resin, during the stirring process, the bubbles accumulate and overflow in the epoxy resin, while the conical block punctures the bubbles floating on the liquid surface, accelerating the bursting of the bubbles, so that the epoxy resin in the processing box 1 can quickly expel the bubbles inside.
