Technical Field

[0001] This utility model belongs to the field of polyurethane resin production technology, specifically a production device for high wear-resistant dry polyurethane resin. Background Technology

[0002] Resins are solid, semi-solid, or sometimes liquid organic polymers at room temperature. In a broad sense, any polymer compound that can be used as a raw material for plastic products is called resin. Resins require the use of stirring devices for auxiliary production during processing. However, in existing resin mixing devices, the raw materials tend to stick to the inner wall during mixing, making subsequent cleaning inconvenient. At the same time, dead corners are easily formed during mixing, resulting in uneven mixing. Therefore, it is necessary to provide a production device for high wear-resistant dry polyurethane resin to overcome the aforementioned defects in the prior art. Utility Model Content

The mixing drum 1 is equipped with a stirring and anti-sticking mechanism 2. The stirring and anti-sticking mechanism 2 includes an N-shaped frame 201, a rotary motor 202, a cross rod 203, a sleeve 204, a stirring blade 205, a rotating ring 206, a scraper 207, and a cross 208. An N-type frame 201 is snapped onto the top of the mixing drum 1. A rotary motor 202 is threaded onto the middle of the bottom of the N-type frame 201. A cross-shaped rotating rod 203 is snapped onto the bottom of the output shaft of the rotary motor 202. A sleeve 204 is fixedly sleeved on the outside of the cross-shaped rotating rod 203 at a position corresponding to the inside of the mixing drum 1. Agitator blades 205 are snapped onto the outside of the sleeve 204 at equal intervals. To facilitate the discharge of the processed resin, a discharge pipe is snapped onto the bottom of the mixing drum 1. The rotary motor 202 is powered by an external power source. A cross groove is opened inside the sleeve 204. Rotating rings 206 are rotatably connected to the top and bottom of the inner wall of the mixing drum 1. Scrapers 207 are equidistantly engaged between the two rotating rings 206. A cross 208 is fixedly sleeved on the outer side of the cross rod 203 corresponding to the inner side of the rotating ring 206. In order to prevent the resin material from sticking to the inner wall of the mixing drum 1, one end of the cross 208 is connected to the inner wall of the rotating ring 206, and the outer side of the scraper 207 is in contact with the inner wall of the mixing drum 1. The top of the mixing drum 1 is provided with a lifting and stirring mechanism 3, which includes a swing frame 301, a rack 302, a half gear 303, a rotating drum 304, a driven gear 305, a lifting traction rod 306, and a lifting pull plate 307. A swing frame 301 is slidably connected to the top of the mixing drum 1 at the position corresponding to the outer side of the cross rotating rod 203. A rack 302 is symmetrically engaged on both the inner and outer sides of the swing frame 301. A half gear 303 is fixedly sleeved on the outer side of the cross rotating rod 203. A rotating drum 304 is rotatably connected to both sides of the top of the mixing drum 1 corresponding to the position of the swing frame 301. A driven gear 305 is engaged at the top of the rotating drum 304. To facilitate the transmission of power, the half gear 303 and the driven gear 305 are respectively engaged with the rack 302. There are four racks 302 in total. A lifting traction rod 306 is threadedly connected to the bottom of the rotating drum 304. A lifting pull plate 307 is movably sleeved at the top position of the outer side of the sleeve 204. To facilitate the lifting and lowering of the sleeve 204, the bottom of the rotating drum 304 passes through the top of the mixing drum 1. The bottom of the lifting traction rod 306 is fixedly connected to the top of the lifting pull plate 307. The threads on the outer sides of the two lifting traction rods 306 rotate in opposite directions. The working principle and usage process of this utility model are as follows: First, the polyurethane resin raw material is prepared and fed into the mixing drum 1. Then, the rotary motor 202 is started, which drives the cross rod 203, sleeve 204 and stirring blade 205 to rotate, so as to stir the polyurethane resin raw material and mix it thoroughly to meet the needs of subsequent processing. At the same time, the cross rod 203 drives the rotating ring 206 and scraper 207 to rotate through the cross 208, which rotates and scrapes the inner wall of the mixing drum 1 to prevent the polyurethane resin raw material from sticking to the inner wall of the mixing drum 1, thus improving the convenience of subsequent cleaning. Finally, during the rotation of the cross-shaped rotating rod 203, the half gear 303 and the rack 302 work together to push the swing frame 301 to swing back and forth at the top of the mixing drum 1. Then, the rack 302 and the driven gear 305 work together to push the rotating drum 304 to rotate, thereby causing the lifting traction rod 306 and the lifting pull plate 307 to move up and down repeatedly. This, in turn, pulls the sleeve 204 and the stirring blade 205 to move up and down along the outside of the cross-shaped rotating rod 203 to stir, further improving the stirring effect.
