[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 5 As shown, a stirring device for polyurethane resin production includes a base plate 1, a tank 10 is provided on the top of the base plate 1, an operating plate 11 is fixedly installed on the top of the base plate 1, the tank 10 is located above the operating plate 11, a rotary stirring mechanism 2 is provided on the top of the operating plate 11, a discharge mechanism 3 is provided on one side of the tank 10, a stabilizing mechanism 4 is provided at the bottom of the base plate 1, and a collecting mechanism 5 is provided on one side of the base plate 1.

[0028] The rotary stirring mechanism 2 includes two mounting plates 201 fixedly installed on the top of the operating plate 11. A motor box 202 is fixedly installed on one side of one of the two mounting plates 201. A motor 203 is fixedly installed on the inner side wall of the motor box 202. A gear 204 is rotatably connected between the two mounting plates 201. The output end of the motor 203 is connected to the gear 204. The motor box 202 is used to protect the motor 203 and prevent it from being damaged by external impact, thus effectively protecting the motor 203.

[0029] An external gear 205 is fixedly installed on the outer wall of the tank 10. The external gear 205 is connected to the gear 204. By starting the motor 203, it rotates in the opposite direction, driving the gear 204 to rotate, which in turn drives the external gear 205 to rotate on the outside of the tank 10. This achieves the rotation of the entire tank 10, thereby realizing double stirring and avoiding the inability of raw materials to be fully mixed evenly, which would lead to uneven color and inconsistent aging speed. This effectively improves the mixing effect and mixing speed.

[0030] like Figure 3 As shown, an installation block 213 is fixedly installed on the top of the operation plate 11. The installation block 213 is located on one side of the two installation plates 201. A circular groove 207 is opened on the top of the installation block 213. A sliding ring 206 is also fixedly installed on the outer wall of the tank body 10. The sliding ring 206 is located on one side of the external gear 205. The sliding ring 206 is slidably connected to the circular groove 207. The installed sliding ring 206 slides inside the circular groove 207 to stabilize the tank body 10 and prevent the tank body 10 from falling off and being damaged when it rotates.

[0031] like Figure 3 As shown, a protective shell 208 is fixedly installed on one side of the tank 10. A motor 209 is fixedly installed on the inner wall of the protective shell 208. A rotating frame 210 is rotatably connected to the inner wall of the tank 10. The output end of the motor 209 is connected to the rotating frame 210. By starting the motor 209, the rotating frame 210 is driven to rotate, causing the scraper 211 to rotate inside the tank 10. While rotating, it drives multiple stirring rollers 212 to stir the raw materials inside, achieving a stirring effect. The installed protective shell 208 is used to protect the motor 209 from external impacts, which could damage the motor 209, thus effectively protecting the motor 209.

[0032] like Figure 3 As shown, multiple scrapers 211 are fixedly installed on one side of the rotating frame 210, and multiple stirring rods 212 are fixedly installed on one side of the multiple scrapers 211. The scrapers 211 are in contact with the inner wall of the tank 10. To further explain, the scrapers 211 are curved. While the multiple scrapers 211 are rotating, they are also used to scrape the inner wall of the tank 10 to prevent the raw materials from sticking to the inner wall of the tank 10.

[0033] like Figure 2As shown, the discharge mechanism 3 includes a sealing plate 31 fixedly installed on the other side of the tank 10. A fixed seat 32 is fixedly installed on one side of the sealing plate 31. A hinge ring 33 is hinged to one side of the fixed seat 32. A rectangular plate 34 is fixedly installed on one side of the hinge ring 33. An electric telescopic rod 35 is fixedly installed on one side of the rectangular plate 34. A hinge plate 37 is hinged to the bottom of the sealing plate 31. A connecting plate 36 is fixedly installed on one side of the hinge plate 37. The output end of the electric telescopic rod 35 is connected to the connecting plate 36. After mixing, the connecting plate 36 is extended and retracted by starting the electric telescopic rod 35. At the same time as the extension and retraction, the hinge ring 33 changes angle, thereby opening the hinge plate 37 and allowing the internal raw materials to be poured out. This avoids uneven feeding and ensures that the feeding is not difficult, effectively improving the feeding speed.

[0034] like Figure 4 As shown, the stabilizing mechanism 4 includes four mounting boxes 41 fixedly installed on the top of the base plate 1. An electric telescopic rod 42 is fixedly installed on the inner top wall of each mounting box 41. An anti-slip block 43 is fixedly installed at the output end of the electric telescopic rod 42. Four casters 44 are fixedly installed at the bottom of the base plate 1, distributed at the four corners of the bottom of the base plate 1. When stable, the electric telescopic rod 42 is activated to extend and retract, causing the anti-slip block 43 to contact the ground, thus separating the casters 44 from the ground and fixing the device in place. This prevents vibration during operation and avoids tipping. Activating the electric telescopic rod 42 again causes the anti-slip block 43 to detach from the ground, allowing the casters 44 to contact the ground and move the device, effectively improving convenience.

[0035] like Figure 5 As shown, the collection mechanism 5 includes a collection cart 51 set on one side of the base plate 1. An inclined block 52 is fixedly installed on one side of the collection cart 51, and pushers 53 are fixedly installed on the left and right sides of the collection cart 51. Anti-slip pads 54 are fixedly installed on the outer side walls of the pushers 53. When moving, the collection cart 51 is used to transport raw materials, the inclined block 52 is used to allow the raw materials to enter the interior of the collection cart 51, and the anti-slip pads 54 are used to prevent slippage when pushing.

[0036] like Figure 3 As shown, an L-shaped feed pipe 6 is fixedly connected to one side of the tank body 10. A feed hopper 7 is fixedly installed on the top of the L-shaped feed pipe 6. A sealing plate 9 is provided on the top of the feed hopper 7. A sealing block 8 is fixedly installed on the bottom of the sealing plate 9. The sealing plate 9 and the feed hopper 7 are interlocked. Raw materials are added through the L-shaped feed pipe 6. The feed hopper 7 is used to collect the raw materials and prevent them from spilling outside. The sealing plate 9 is used to seal the feed hopper 7. To further explain, the interlocking of the sealing plate 9 and the feed hopper 7 prevents the sealing plate 9 from falling off when the tank body 10 rotates.

[0037] The implementation principle of this application is as follows: During use, starting motor 203 rotates in the opposite direction, driving gear 204 to rotate, which in turn drives external gear 205 to rotate on the outside of tank 10, thus achieving overall rotation of tank 10 and achieving double stirring, effectively improving the mixing effect and mixing rate. Starting motor 209 drives rotating frame 210 to rotate, causing scraper 211 to rotate inside tank 10. While rotating, multiple stirring rollers 212 stir the internal raw materials, achieving a stirring effect. The installed protective shell 208 protects motor 209 from external impacts, effectively protecting motor 209. After mixing is completed, starting electric telescopic rod 35 drives connecting plate 36 to extend and retract. While extending and retracting, the angle of hinge ring 33 changes, thereby connecting the hinge... Plate 37 is opened to allow the internal raw materials to pour out, preventing uneven feeding and thus improving feeding speed. When stable, the electric telescopic rod 42 is activated to extend or retract, causing the anti-slip block 43 to contact the ground, thereby separating the caster wheel 44 from the ground and fixing the device in place. This prevents vibration and tipping during operation. Activating the electric telescopic rod 42 again causes the anti-slip block 43 to detach from the ground, allowing the caster wheel 44 to contact the ground and move the device, effectively improving convenience. The L-shaped feed pipe 6 is used to add raw materials, and the installed feed hopper 7 is used to collect the raw materials, preventing spillage. The installed sealing plate 9 is used to seal the feed hopper 7. Furthermore, the sealing plate 9 engages with the feed hopper 7 to prevent it from falling off when the tank 10 rotates.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
