Description
Technical Field
[0001] The utility model relates to the technical field of polyester resin mixing devices, in particular to a high-efficiency polyester resin mixing device. Background Art
[0002] The polyester resin mixing device is a device used to mix polyester resin raw materials, and its design purpose is to achieve uniform mixing of the resin raw materials.
[0003] When a functional mixing device is used to mix and process polyester resin, the polyester resin is placed in a mixing barrel, and then the barrel cover is closed and the motor is started to drive the stirring rod arranged inside to stir and mix the polyester resin. The existing stirring rod is usually arranged at the center of the mixing barrel. Since the polyester resin has a certain viscosity, when it is stirred, it is easy to adhere to the stirring rod and rotate with the stirring rod, and is in a stationary state relative to the stirring rod. This makes it impossible to stir the resin evenly when adding other ingredients such as a curing agent, resulting in insufficient stirring. At the same time, during the stirring process, some polyester resins adhered to the wall of the mixing barrel cannot be fully stirred, thereby affecting the quality and performance of the polyester resin. Utility Model Content

When the functional mixing device is used to mix and process the polyester resin, the polyester resin is placed in the mixing barrel 1, and then the two stirring rods 25 and the first circular shaft 23 and the second circular shaft 24 are placed in the mixing barrel 1, and then the barrel cover 4 is covered. At this time, the starting motor 21 drives the transmission circular shaft 22 to rotate. Driven by the belt 27, the first circular shaft 23 and the second circular shaft 24 can be driven to rotate on the inner wall of the barrel cover 4, thereby driving the two stirring rods 25 to rotate while staggered, so that the polyester resin inside the mixing barrel 1 is stirred to avoid the polyester resin adhering to the stirring rod 25 during stirring and rotating with it, resulting in insufficient stirring and mixing. At the same time, when the stirring rod 25 rotates, it will drive the scraper 26 to scrape off the inner wall of the mixing barrel 1 to avoid the polyester resin adhering to the inner wall of the mixing barrel 1 and causing the polyester resin to fail to stir. Therefore, it can be fully stirred to avoid affecting the quality and performance of the polyester resin.
[0030] Reference Figure 2 and Figure 3 As shown, the embodiment discloses that the cross-sections of both ends of the stirring rod 25 are rhombus-shaped, and the two stirring rods 25 are centrally symmetrical. By setting the two ends of the stirring rod 25 in a rhombus shape, the two sides of the stirring rod 25 are sharp, so that when the polyester resin is staggered and stirred, the sharp two sides will cut the viscous polyester resin, thereby preventing the polyester resin from sticking together and being unable to be stirred.
[0031] Reference Figure 2 and Figure 3As shown, the present embodiment discloses that the outer surfaces of the transmission circular shaft 22, the first circular shaft 23 and the second circular shaft 24 are all fixedly connected with a plurality of limit ring blocks 28, and the belt 27 is arranged between two adjacent limit ring blocks 28. By setting the limit ring blocks 28, the two sides of the belt 27 can be limited, so that it is not easy to shake in the process of driving the first circular shaft 23 and the second circular shaft 24 to rotate. The outer surfaces of one end of the first circular shaft 23 and the second circular shaft 24 are symmetrically fixedly connected with reinforcement rods 29, and one side of the two pairs of reinforcement rods 29 is fixedly connected to one side of the two stirring rods 25 respectively.

When using the mixing barrel 1 to mix and stir the polyester resin, before placing it, one end of the support rod 33 and the two threaded rods 34 can be manually inserted into the inner walls of the slot block 31 and the two rectangular grooves 32 respectively, and then one end can be butted against the ground. At this time, hold the screw hole block 35 and spirally move it on the threaded rod 34 to a certain position, so that one side of it can be butted against one side of the slot block 31, so that the support rod 33 can be fixed on the slot block 31 when supported on the ground, and the outer surface of the mixing barrel 1 can be supported and stabilized, so that it is not easy to be damaged by external force during use.
[0033] Reference Figure 4 and Figure 5As shown, the present embodiment discloses that the outer surface of the screw hole block 35 is fixedly connected with a plurality of screw blocks 36, and the plurality of screw blocks 36 are arranged at equal distances. By setting the screw blocks 36, the contact area of the outer surface of the screw hole block 35 can be increased, so that it is convenient to manually hold and twist it. One side of the screw hole block 35 is fixedly connected with an anti-sliding block 37, and the anti-sliding block 37 is made of rubber. By setting the anti-sliding block 37, the contact friction force on one side of the screw hole block 35 can be increased, so that it is not easy to rotate and loosen when it abuts on one side of the slot block 31, and the abutment is more firm. Both ends of one side of the slot block 31 are symmetrically fixedly connected with a limiting plate 38, and the two limiting plates 38 are fixed on both sides of the entrance of the rectangular slot 32 in an inclined manner.

At this time, the starting motor 21 will drive the transmission circular shaft 22 to rotate. Driven by the belt 27, the first circular shaft 23 and the second circular shaft 24 can be driven to rotate on the inner wall of the barrel cover 4, thereby driving the two stirring rods 25 to rotate while staggered, so that the polyester resin inside the mixing barrel 1 is stirred to avoid the polyester resin adhering to the stirring rod 25 during stirring and rotating with it, resulting in insufficient stirring and mixing. At the same time, when the stirring rod 25 rotates, it will drive the scraper 26 to scrape off the inner wall of the mixing barrel 1 to avoid the polyester resin adhering to the inner wall of the mixing barrel 1 and causing the polyester resin to fail to stir. Therefore, it can be fully stirred to avoid affecting the quality and performance of the polyester resin.
