[0032] Please see Figures 1-4 In this embodiment of the present invention, a quantitative feeding and mixing device for epoxy resin curing agent includes a mixing tank 1. The upper end of the mixing tank 1 is open and a matching fixing plate 3 is fixedly installed. A first valve 7 connected to the inside of the mixing tank 1 is installed in the middle of the lower surface of the mixing tank 1. An epoxy resin feed pipe 10 connected to the inside of the mixing tank 1 is installed in the middle of one side of the upper surface of the fixing plate 3. A second valve 8 connected to the inside of the mixing tank 1 is installed in the middle of the side of the upper surface of the fixing plate 3 away from the epoxy resin feed pipe 10. A quantitative cylinder 12 connected to the second valve 8 is installed above the second valve 8. A third... A rotating rod 14 is rotatably mounted on the lower surface of valve 9 and fixed plate 3. Several connecting rods 15 are fixed vertically at intervals on both sides of the outer ring surface of the rotating rod 14. After the curing agent is delivered into the metering cylinder 12 and the metering cylinder 12 is filled with curing agent, the curing agent to be fed is metered. In use, the metering cylinder 12 helps to meter the epoxy resin curing agent, so as to control the proportion of epoxy resin curing agent fed, avoid errors when feeding epoxy resin curing agent, and help ensure the stability of epoxy resin product performance.

[0033] The rotating rod 14 is vertical, with its upper end penetrating the upper and lower surfaces of the fixed disk 3. The upper end of the outer ring of the rotating rod 14 is rotatably connected to the middle of the fixed disk 3 via a bearing. The fixed disk 3 helps to limit the rotation of the rotating rod 14, facilitating stable rotation. A rotating motor 13 is installed on the middle of the upper surface of the fixed disk 3, corresponding to the rotating rod 14. The output shaft of the rotating motor 13 faces downward, and its lower end is fixedly connected to the upper end of the rotating rod 14. The rotating motor 13 helps to drive the rotating rod 14 to rotate, facilitating its use. A connected curing agent inlet pipe 11 is installed on the upper side of the third valve 9. The curing agent inlet pipe 11 is vertical. Vertical support legs 2 are fixed around the lower edge of the mixing tank 1. The support legs 2 can support and limit the mixing tank 1, facilitating stable use.

[0034] A scraper 16 is fixed to the end of the connecting rod 15 located on the same side away from the rotating rod 14. The surface of the scraper 16 away from the connecting rod 15 is in a matching fit with the corresponding position on the inner wall of the mixing tank 1. The connecting rod 15 helps to connect the rotating rod 14 and the scraper 16. A matching retention hole 4 is opened at the bottom of the mixing tank 1 corresponding to the inner side of the first valve 7. The retention hole 4 penetrates the inner and outer surfaces of the corresponding position on the mixing tank 1. The retention hole 4 facilitates communication between the inside of the mixing tank 1 and the inside of the first valve 7.

[0035] A matching first through hole 5 is provided on the inner ring surface of the epoxy resin feed pipe 10 on the fixed plate 3. The first through hole 5 penetrates the upper and lower surfaces of the fixed plate 3 at the corresponding position. The first through hole 5 facilitates communication between the epoxy resin feed pipe 10 and the mixing tank 1. A matching second through hole 6 is provided on the inner side of the second valve 8 on the fixed plate 3. The second through hole 6 penetrates the upper and lower surfaces of the fixed plate 3 at the corresponding position. The second through hole 6 facilitates communication between the second valve 8 and the mixing tank 1.

[0036] The working principle of this utility model is as follows: During use, the support leg 2 is placed stably in the position where it is to be used, which facilitates stable use of the support leg 2. The support leg 2 can support and limit the mixing tank 1 and the various components assembled on the mixing tank 1, which helps to stably use the mixing tank 1 and the various components assembled on the mixing tank 1. The mixing tank 1 can support and limit the fixed plate 3 and the various components assembled on the fixed plate 3, which facilitates stable use of the fixed plate 3 and the various components assembled on the fixed plate 3.

[0037] The upper end of the epoxy resin feed pipe 10 is connected to an external pipe for conveying epoxy resin, and the upper end of the curing agent feed pipe 11 is connected to an external pipe for conveying curing agent. Furthermore, the equipment for collecting the epoxy resin and curing agent mixture is connected to the lower side of the first valve 7. When epoxy resin needs to be conveyed into the mixing tank 1, the external pipe for conveying epoxy resin can convey epoxy resin into the mixing tank 1 through the epoxy resin feed pipe 10 and the first through hole 5 on the fixed plate 3.

[0038] When the curing agent needs to be delivered to the mixing tank 1, the third valve 9 is opened. With the third valve 9 open, the external pipeline for delivering the curing agent can deliver the curing agent to the metering cylinder 12 through the curing agent inlet pipe 11 and the third valve 9. When the metering cylinder 12 is full of curing agent, the third valve 9 is closed. After the third valve 9 is closed, the second valve 8 is opened. With the second valve 8 open, the metered amount of curing agent in the metering cylinder 12 will be delivered to the mixing tank 1 through the second valve 8 and the second through hole 6 on the fixed plate 3, so as to facilitate the metered delivery of the curing agent.

[0039] When it is necessary to mix the epoxy resin and the curing agent evenly, the rotating motor 13 is turned on. When the rotating motor 13 is turned on, the output shaft of the rotating motor 13 can drive the rotating rod 14 to rotate. When the rotating rod 14 rotates, it can drive the connecting rod 15 to rotate. When the connecting rod 15 rotates, it can drive the scraper 16 to rotate. When the connecting rod 15 and the scraper 16 rotate, they can mix the epoxy resin and the curing agent in the mixing tank 1, so that the epoxy resin and the curing agent are in a uniform state. When the scraper 16 rotates, it can scrape the inner wall of the mixing tank 1, which can prevent the epoxy resin and the curing agent from adhering to the inner wall of the mixing tank 1.

[0040] After the epoxy resin and curing agent are stirred evenly, the first valve 7 is opened. With the first valve 7 open, the epoxy resin and curing agent mixture in the mixing tank 1 will be discharged to the outside through the inlet hole 4 on the mixing tank 1 and the first valve 7 to a device for collecting the epoxy resin and curing agent mixture, so as to collect the evenly stirred epoxy resin and curing agent mixture.

[0041] During use, the metering cylinder 12 helps to quantitatively feed the epoxy resin curing agent, so as to control the proportion of epoxy resin curing agent to be fed, avoid errors in feeding the epoxy resin curing agent, and help ensure the stability of the performance of epoxy resin products.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
