It can resist the erosion of various waters, oils, solvents and chemicals, and has the characteristics of antibacterial and mildew-proof. It is widely used in the bonding and sealing of building door and window glass and automotive windshield. The manufacturing process of polyurethane binder involves reacting isocyanate with polyol to form a polyurethane prepolymer, and then adding fillers, catalysts, solvents and other components for formulation according to different application requirements.

[0003] The existing polyurethane binder needs to be quantitatively proportioned and mixed with a specified catalyst during actual construction, and then stirred with sand and gravel to form construction materials. Since the existing polyurethane binder and catalyst are usually placed in a mixing barrel and stirred by a stirrer during mixing, and the mixture of polyurethane binder and catalyst needs to be taken out of the mixing barrel using a container, a large amount of the mixture of polyurethane binder and catalyst will drip during the material taking process, resulting in waste. Therefore, the existing mixing barrel for polyurethane binder and catalyst has inconvenient use. For this reason, we provide a polyurethane binder and catalyst quantitative proportioning and stirring device. Content of the Utility Model

[0027] Embodiment 1

[0028] As Figures 1-6As shown in the figure, the utility model provides a technical solution: a polyurethane binder and catalyst quantitative ratio stirring device, including: a stirring barrel 1, a material taking mechanism 2 is arranged at the bottom of the stirring barrel 1, the material taking mechanism 2 includes a feeding pipe 21 fixedly connected to the stirring barrel 1, a fixing pipe 22 is fixedly connected to the outer surface of the feeding pipe 21, a sliding rod 23 is sleeved inside the fixing pipe 22, the sliding rod 23 is slidably connected to the fixing pipe 22, a blocking block 24 is sleeved inside the feeding pipe 21, the blocking block 24 is slidably connected to the feeding pipe 21, a rubber sleeve 25 is sleeved on the outer surface of the blocking block 24, the rubber sleeve 25 is fixedly connected to the blocking block 24, one end of the blocking block 24 is fixedly connected to a connecting plate 26, the connecting plate 26 is fixedly connected to the sliding rod 23, a limiting piece 27 is fixedly connected to the end of the sliding rod 23 placed inside the fixing pipe 22, a spring 28 is sleeved on the outer surface of the sliding rod 23, and both ends of the spring 28 are respectively fixedly connected to the outer surface of the limiting piece 27 and the inner wall of the fixing pipe 22, a fixing rod 29 is fixedly connected to the outer surface of the feeding pipe 21, one end of the fixing rod 29 is fixedly connected to a connecting block 201, a clamping plate 202 is sleeved inside the connecting block 201, the clamping plate 202 is slidably connected to the connecting block 201, and an anti - detachment block 203 is fixedly connected to the outer surface of the clamping plate 202.

[0029] In this embodiment, by setting the material taking mechanism 2, it enables construction workers to more conveniently take out the mixture of polyurethane binder and catalyst in the stirring barrel 1. The setting of the blocking block 24 and the rubber sleeve 25 can ensure that the mixture will not leak out. The setting of the spring 28, and the elastic force of the spring 28 can indirectly act on the blocking block 24 to ensure that the rubber sleeve 25 fits more tightly with the feeding pipe 21. At the same time, the elastic force generated by the compression of the spring 28 can automatically reset the adjusted sliding rod 23, blocking block 24 and rubber sleeve 25, so that the mixture remaining in the feeding pipe 21 will not drip onto the ground. The setting of the clamping plate 202 can be used to limit the pulled connecting plate 26, so that construction workers do not need to continuously pull the connecting plate 26. At the same time, the setting of the anti - detachment block 203 can prevent the clamping plate 202 from detaching from the connecting block 201.

[0030] Embodiment 2

[0031] As Figures 1-6As shown in the figure, an auxiliary mechanism 3 is provided at the top of the material taking mechanism 2. The auxiliary mechanism 3 includes a baffle 31. The baffle 31 is sleeved inside the mixing barrel 1. The baffle 31 is slidably connected to the mixing barrel 1. An external connection block 32 is fixedly connected to the outer surface of the mixing barrel 1. A threaded rod 33 is sleeved inside the external connection block 32. A guide rod 34 is fixedly connected to the top of the external connection block 32. Threaded sleeve rods 35 are sleeved on the outer surfaces of both the threaded rod 33 and the guide rod 34. The threaded sleeve rod 35 is threadedly connected to the threaded rod 33. The threaded sleeve rod 35 is slidably connected to the guide rod 34. The threaded sleeve rod 35 is fixedly connected to the baffle 31. One end of the threaded rod 33 placed inside the external connection block 32 is fixedly connected to a rotating piece 36. The rotating piece 36 is rotatably connected to the external connection block 32. One end of the threaded rod 33 away from the rotating piece 36 is fixedly connected to a rotating handle 37.

[0032] In this embodiment, by setting the auxiliary mechanism 3, it can be used to control whether the mixture of polyurethane binder and catalyst leaks or the leakage speed, and can better cooperate with the plug 24 to throttle the mixture at the material conveying pipe 21. At the same time, it ensures that the polyurethane binder and catalyst raw materials that have not been stirred completely will not enter the material conveying pipe 21. In addition, the threaded rod 33 is provided, and the threaded rod 33 can perform threaded driving on the threaded sleeve rod 35, so that the threaded sleeve rod 35 can adjust the position of the baffle 31.

[0033] Working principle:

[0034] As Figures 1-6As shown in the figure, when the utility model is in use, the proportioned polyurethane binder and catalyst can be first put into the mixing barrel 1. Then, a stirrer is used to fully stir the mixture of the polyurethane binder and catalyst in the mixing barrel 1. When it is necessary to take out the mixture, the connection between the plug 24 and the feeding pipe 21 can be first contacted. At this time, the connecting plate 26 is pulled, and the plug 24 and the rubber sleeve 25 are driven by the connecting plate 26 to disengage from the feeding pipe 21. At the same time, the connecting plate 26 drives the limiting piece 27 to slide by means of the sliding rod 23, and the limiting piece 27 compresses the spring 28 when sliding, so that the spring 28 generates elastic force. Then, when the connecting plate 26 is pulled to an appropriate position, the clamping plate 202 can be pushed to limit the connecting plate 26 by means of the clamping plate 202. Then, the turning handle 37 is used to drive the threaded rod 33 to rotate, and the threaded rod 33 thread-drives the threaded sleeve rod 35 under the cooperation of the rotating piece 36 and the guide rod 34, so that the threaded sleeve rod 35 can drive the baffle 31 to move upward. Thus, the mixture of the polyurethane binder and catalyst in the mixing barrel 1 can leak into the feeding pipe 21 and flow into the specified container through the feeding pipe 21. When a certain amount of the mixture is taken out, the turning handle 37 can be rotated in the reverse direction again to gradually reset the baffle 31 by means of the threaded rod 33. When the flow rate of the mixture at the feeding pipe 21 is low, the clamping plate 202 can be pulled. At this time, the connecting plate 26 and the plug 24 will be reset under the action of the elastic force of the spring 28 to block the feeding pipe 21, so that the remaining mixture in the feeding pipe 21 will not drip, thereby ensuring that the mixture of the polyurethane binder and catalyst will not be wasted.

[0035] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
