Description

Technical Field

[0001] This utility model relates to the field of epoxy resin processing, specifically a mixing device for processing liquid epoxy resin without residue. Background Technology

[0002] Epoxy resin processing mixing equipment is an industrial equipment specifically designed to uniformly mix epoxy resin matrix with additives such as curing agents, fillers, and pigments to prepare epoxy resin composite materials that meet performance requirements. Its core function is to achieve full integration of each component at the molecular or microscopic level through mechanical stirring, dispersion, or shearing, ensuring that the material has excellent mechanical strength, chemical stability, and insulation properties after curing.

[0003] Chinese Patent Publication No. CN221182641U discloses a mixing device for producing epoxy resin adhesive, including a mixing tank. Two positioning rings are fixedly provided on the outer wall of the mixing tank, and two second fixing rings are fixedly provided on the outer wall of the positioning rings. Air is discharged into the mixing tank by a pressure pump to pressurize the mixing tank. A valve provided on the discharge pipe is opened, and the epoxy resin adhesive is squeezed out of the mixing tank by the air pressure in the mixing tank, which avoids the epoxy resin adhesive from sticking and blocking in the pipe and facilitates the discharge of epoxy resin adhesive from the mixing container.

[0004] During the use and mixing process of the aforementioned patented epoxy resin adhesive production mixing device, when the subsequently added materials are transferred from the feed pipe to the mixing position, the device still has shortcomings in the feeding stage. When feeding materials into the mixing tank, viscous epoxy resin and curing agent tend to adhere and remain on the inner wall of the feed pipe, and cannot all enter the mixing area. This leads to a deviation in the actual material ratio involved in the mixing, which not only wastes raw materials, but also affects the curing uniformity, final mechanical and chemical properties of the epoxy resin composite material. Utility Model Content

[0005] The purpose of this invention is to provide a mixing device for processing epoxy resin with no liquid residue. The second valve at the bottom of the temporary storage tank can be opened directly to discharge the material to be added. Most importantly, the blower can draw gas and blow the gas to move the material remaining inside the temporary storage tank, providing the force to squeeze out the material adhering to the inner wall of the temporary storage tank. This avoids some material remaining on the inner wall of the temporary storage tank, avoids material waste, and also ensures the processing effect of epoxy resin, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for processing liquid epoxy resin without residue, comprising a stirring frame, five temporary storage tanks evenly distributed around the upper end of the stirring frame, a sealing cap sealed at the upper end of the outer side of each temporary storage tank, a through hole provided inside the sealing cap, and a flexible hose sealed at the upper end of the sealing cap. The upper ends of the five flexible hoses are sealed and connected through a first transmission pipe, a second transmission pipe is provided on the side of the first transmission pipe, and a fan is provided at one end of the second transmission pipe. By starting the fan, gas can be drawn out, and the gas blows and squeezes out the material retained inside the temporary storage tank, thus avoiding material retention inside the temporary storage tank and preventing insufficient material addition from affecting epoxy resin processing.

[0007] Preferably, a filter box is provided on the side of the blower, and the filter box is sealed to the upper end of the stirring frame through a third transmission pipe. The filter box, blower, second transmission pipe and hose are sequentially sealed and connected. The gas is drawn in from the upper end inside the stirring frame and filtered through the filter box.

[0008] Preferably, the filter box is provided with a filter element inside, and a mounting plate is provided on the outside of the filter box. The mounting plate is fixedly connected to the filter box by bolts. After the gas flows into the filter box, it is filtered when passing through the filter element.

[0009] Preferably, a second valve is provided at the lower end of the temporary storage tank, and a second discharge pipe is provided at the lower end of the second valve. When the corresponding material is discharged, the second valve at the lower end of the material is opened, so that the corresponding material can be discharged, which can adapt to the processing requirements of different epoxy resins.

[0010] Preferably, a scale is provided on the side of the temporary storage container, and the amount of material to be added to the temporary storage container in advance is referenced by the scale.

[0011] Preferably, the outer wall of the first transmission tube is provided with a bracket, which can support the upper end of the first transmission tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention allows materials to be added to a temporary storage container beforehand. During the addition process, a scale allows for control of the amount of material added. After the corresponding material is added, a sealing cap is placed over the top of the container to protect the material. Furthermore, when additional materials are needed, the second valve at the bottom of the temporary storage container opens and discharges the required material. Most importantly, a blower draws in gas and blows away any remaining material inside the container, providing the force to expel material adhering to the inner wall of the container. This prevents material from remaining on the inner wall, avoiding waste and ensuring the optimal processing effect of the epoxy resin. Attached Figure Description

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] like Figure 1 As shown, a mixing device for processing liquid epoxy resin without residue according to this embodiment includes a stirring frame 1, and a stirring paddle 12 is provided inside the stirring frame 1. The stirring paddle 12 can rotate and stir the material inside after being driven, thereby realizing the processing of epoxy resin.

[0021] When stirring epoxy resin, not all materials are added at the beginning. Materials that need to be added later need to be pre-stored. Five temporary storage containers 2 are evenly distributed around the upper part of the stirring frame 1. These five temporary storage containers 2 can store different materials, such as… Figure 2As shown, a second valve 15 is provided at the lower end of the temporary storage tank 2, and a second discharge pipe 16 is provided at the lower end of the second valve 15. After the second valve 15 is opened, the material stored inside the temporary storage tank 2 can be discharged from the position of the second discharge pipe 16.

[0022] To facilitate the loading of materials into the temporary storage container 2, a scale 3 is provided on the side of the temporary storage container 2. The scale 3 is welded and fixed to the temporary storage container 2 and the mixing frame 1 respectively. The scale 3 can provide a reference for the amount of material.

[0023] Furthermore, in order to protect the materials temporarily stored inside the temporary storage tank 2, such as... Figure 3 As shown, a sealing cover 4 is provided at the upper end of the exterior of the temporary storage tank 2, and the exterior of the sealing cover 4 is sealed to the interior of the temporary storage tank 2. A through hole is provided inside the sealing cover 4, and a flexible hose 5 is provided at the upper end of the sealing cover 4, and the flexible hose 5 is sealed to the sealing cover 4. The gas transmitted at the position of the flexible hose 5 can pass through the sealing cover 4 and blow the interior of the temporary storage tank 2, which can actively discharge the material adhering to the inner wall of the temporary storage tank 2 and push the material out from the position of the second discharge pipe 16.

[0024] To facilitate gas transmission, the upper ends of the five hoses 5 are sealed together by the first transmission pipe 6. The side of the first transmission pipe 6 is provided with a second transmission pipe 8, and one end of the second transmission pipe 8 is provided with a fan 9. By starting the fan 9, gas can be drawn and sent from the first transmission pipe 6 and the hoses 5 into the temporary storage tank 2. The flexibility of the hoses 5 makes it easy to remove the sealing cap 4, facilitate the installation of the sealing cap 4, and the subsequent addition of materials.

[0025] A filter box 10 is provided on the side of the blower 9. The filter box 10 is sealed to the upper end of the stirring frame 1 through a third transmission pipe 11. The extracted gas is drawn from the upper end of the stirring frame 1 through the third transmission pipe 11 to avoid drawing external gas and causing material contamination.

[0026] The filter box 10, the blower 9, the second transmission pipe 8 and the hose 5 are sequentially and sealed together. After the blower 9 draws out the gas, the gas is transmitted along the third transmission pipe 11, the second transmission pipe 8, the first transmission pipe 6 and the hose 5 and then sent into the interior of the temporary storage tank 2. The gas actively discharges the material that is stuck on the inner wall of the temporary storage tank 2, so that the material can be completely discharged and the material is prevented from being stuck inside the temporary storage tank 2.

[0027] In order to support the first transmission pipe 6, a bracket 7 is provided on the outer wall of the first transmission pipe 6, and the two ends of the bracket 7 are fixedly connected to the first transmission pipe 6 and the stirring frame 1 respectively by glue.

[0028] After the epoxy resin is processed, when the material needs to be discharged from the mixing frame 1, a first discharge pipe 13 is provided at the middle position of the lower end of the mixing frame 1, and a first valve 14 is provided at the lower end of the first discharge pipe 13. After the first valve 14 is opened, the processed material can be discharged from the position of the first discharge pipe 13.

[0029] To facilitate the filtration of the gas drawn by the blower 9, thereby improving the quality of the gas circulating inside the mixing frame 1, such as... Figure 4 As shown, the filter box 10 is equipped with a filter element 18 inside and a mounting plate 17 is provided on the outside of the filter box 10. The mounting plate 17 is fixedly connected to the filter box 10 by bolts. After the bolts pass through, the mounting plate 17 can be disassembled and the filter element 18 can be replaced.

[0030] Working principle: When using the device to process epoxy resin, the material to be added is poured into the temporary storage tank 2. The amount of material added into the temporary storage tank 2 is determined based on the scale 3. The epoxy resin is stirred and processed inside the mixing frame 1. When additional material needs to be added during the processing, the second valve 15 at the bottom of the temporary storage tank 2 is opened. After the material inside the temporary storage tank 2 is no longer restricted by the second valve 15, it is discharged from the second discharge pipe 16. The blower 9 is turned on. The blower 9 draws the gas from the upper part of the mixing frame 1 through the third transmission pipe 11. The gas is filtered by the filter element 18 and transmitted along the second transmission pipe 8. The gas inside the second transmission pipe 8 is transmitted from the first transmission pipe 6 to the temporary storage tank 2. The gas can push the material remaining on the inner wall of the temporary storage tank 2, so that the material can be completely discharged into the mixing frame 1, realizing the complete discharge of gas inside the temporary storage tank 2.
