DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figures 1-3 As shown, a polyurethane composite material canning device includes a bracket 1, a conveying member arranged below the bracket 1, and a mixing tank 3 and a sealing tank 6 installed on the bracket 1. The bottom end of the mixing tank 3 is connected to a discharge valve 7, and the mixing tank 3 is installed with a feed pipe 4. The bottom end of the discharge valve 7 is connected to the top of the sealing tank 6. The bottom end of the sealing tank 6 is installed with a discharge valve 8, and the interior of the sealing tank 6 is installed with a liquid level sensor 14. The bottom of the bracket 1 is provided with four support columns 23 for supporting it, and the bracket 1 is also provided with an adjustment structure;

[0024] The adjustment structure includes a connecting frame 11 fixed on both sides of the bracket 1, and a mounting frame 12 installed between two support columns 23 on the same side. A hydraulic cylinder 13 is installed on both mounting frames 12, and the telescopic end of the hydraulic cylinder 13 is fixedly connected to the bottom of the connecting frame 11. A telescopic auxiliary rod is also connected between the connecting frame 11 and the mounting frame 12.

[0025] Specifically, regarding the above-mentioned conveying member, such as Figures 1-3 As shown, it includes a conveying frame 2 with a cavity inside, two conveying rollers 15 are rotatably installed in the cavity, and a conveyor belt 16 is connected between the two conveying rollers 15. A second motor 10 is fixed on one side of the conveying frame 2 to drive one of the conveying rollers 15 to rotate.

[0026] Through the above, when in use, the raw materials and ingredients of the polyurethane composite material can be added into the mixing tank 3 through the feeding pipe 4 for mixing to obtain the polyurethane composite material, and then the empty barrels are placed on the conveyor belt 16 in turn, and the conveying roller 15 is driven by the second motor 10 to rotate, so that the conveying roller 15 drives the conveyor belt 16 to rotate to transport the empty barrel until the empty barrel is transported to the bottom of the sealed tank 6. At this time, the second motor 10 stops running and opens the discharge valve 7 to discharge the composite material formed in the mixing tank 3 into the sealed tank 6. At this time, the liquid level sensor 14 monitors the liquid level of the composite material in the sealed tank 6 in real time, and when the amount of composite material in the sealed tank 6 reaches the volume of the empty barrel, the discharge valve 7 is closed and the discharge valve 8 is opened to load the composite material in the sealed tank 6 into the empty barrel, and then the filled barrel is transported out by the conveyor belt 16 to facilitate entering the next process, and this reciprocating process can realize the assembly line filling of the polyurethane composite material;

[0027] And during the filling process, when the volume of the barrel is large and its height is high, the hydraulic cylinder 13 on the mounting frame 12 can be used to drive the connecting frame 11 to rise, so that the connecting frame 11 drives the bracket 1 and the mixing tank 3 and the sealing tank 6 to rise as a whole. At this time, the distance between the discharge valve 8 and the barrel mouth of the barrel becomes larger until the height of the barrel is met, and then the polyurethane combination material is filled into the barrel through the discharge valve 8. Conversely, the hydraulic cylinder 13 is used to drive the connecting frame 11 to descend, so that the connecting frame 11 drives the bracket 1 and the mixing tank 3 and the sealing tank 6 to descend as a whole, so that the distance between the discharge valve 8 and the barrel mouth of the barrel becomes smaller to meet the needs of smaller barrels, thereby realizing that the filling device can adapt to barrels of different specifications, so as to facilitate the loading of polyurethane combination materials into barrels of different specifications to meet different production needs, thereby improving the practicality of the filling device and facilitating the efficient filling of polyurethane combination materials.

[0028] At the same time, in this embodiment, Figure 1 and Figure 2As shown, the mixing tank 3 is also provided with a stirring mechanism 5, and the stirring mechanism 5 includes a first motor 51 fixed to the top of the mixing tank 3, and a shaft 52 rotatably installed inside the mixing tank 3, and the shaft 52 is provided with stirring rods 53 distributed at equal intervals along its axial direction.

[0029] When the raw materials and ingredients of the polyurethane combination are added to the mixing tank 3 for mixing, the shaft 52 can be driven to rotate by the first motor 51, so that the shaft 52 drives the stirring rod 53 to rotate, so as to stir the raw materials and ingredients and make them fully mixed, thereby facilitating the rapid preparation of the polyurethane combination and facilitating the subsequent filling operation.

[0030] In addition, in one embodiment, Figures 2-4 As shown, a collection frame 22 and two support rods 20 are also installed at the inner bottom of the cavity, and a cleaning piece 19 is installed at the top of the two support rods 20. A collection chamber is provided inside the collection frame 22, and a discharge pipe 21 connected to the collection chamber is installed at the bottom end of the conveyor frame 2. The cleaning piece 19 is below the conveyor belt 16, and the top of the cleaning piece 19 is in contact with the conveyor belt 16. The cleaning piece 19 can be made of sponge or cotton cloth.

[0031] Furthermore, one side of the cleaning member 19 adjacent to the aggregate frame 22 is beveled to form a scraping portion.

[0032] Through the above, in the process of conveying the material barrel by the conveyor belt 16, the conveyor belt 16 rotates continuously. At this time, the cleaning part 19 in the conveying frame 2 contacts the conveyor belt 16, and under the rotation of the conveyor belt 16, the cleaning part 19 cleans the conveyor belt 16, and scrapes the material dripping on the conveyor belt 16 through the scraping part on one side thereof, so that the material dripping on the conveyor belt 16 falls into the collection chamber in the collection frame 22, and can finally be discharged through the discharge pipe 21, thereby not only cleaning the conveyor belt 16 and preventing scaling on the conveyor belt 16, but also recycling the material, thereby improving the practicality of the device.

[0033] At the same time, in this embodiment, Figure 2 and Figure 4 As shown, the bottom ends of the two cleaning pieces 19 are each installed with a connecting plug 18, the top ends of the two support rods 20 are each provided with a connecting groove for the connecting plug 18 to be inserted, and one side of the two support rods 20 is provided with a latch rod 17 that passes through the connecting plug 18, and an inspection door 9 is hinged on one side of the conveying frame 2.

[0034] When the cleaning member 19 needs to be replaced, the inspection door 9 can be opened, and the latch rod 17 can be pulled out from the support rod 20, and then the cleaning member 19 can be pulled so that the connecting plug 18 is moved out of the connecting groove at the top of the support rod 20, so as to take the cleaning member 19 out of the conveyor frame 2 and realize the disassembly of the cleaning member 19, and then the new cleaning member 19 can be inserted into the conveyor frame 2, and the connecting plug 18 can be inserted into the connecting groove, and then the latch rod 17 can be inserted into the support rod 20 to plug and fix the connecting plug 18 and the support rod 20, completing the installation of the cleaning member 19, and closing the inspection door 9 to complete the replacement of the cleaning member 19, thereby ensuring the normal use of the cleaning member 19 and facilitating the effective cleaning of the conveyor belt 16.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
