Description

Technical Field

[0001] The utility model relates to the technical field of ultra-high molecular weight polyethylene, in particular to a material balancing device for producing ultra-high molecular weight polyethylene plates. Background Art

[0002] Ultra-high molecular weight polyethylene is the best quality polyethylene currently available and can be used in harsh working environments and for a variety of purposes. It has excellent applicability in many difficult application conditions.

[0003] The unique quality of this polymer is its ultra-high molecular weight, which ranges from 3 to 6 million, while high-density polyethylene resins only range from 300,000 to 500,000. This difference ensures that UHMW-PE has sufficient strength to achieve wear and impact resistance that other lower polymer products cannot have. The ultra-high molecular weight of UHMW-PE means that it will not melt and flow like a liquid, so the processing method is derived from powder metal technology. Traditional plastic processing technologies, such as injection molding, blow molding and heat setting, cannot be applied to UHMW-PE. Extrusion molding is the most common processing technology applied to this resin, which produces a tougher product.

[0004] A kind of ultra-high molecular weight polyethylene sheet material distribution structure disclosed in the Chinese utility model patent application disclosure CN 217395386 U includes a material box body, a partition is fixed at the bottom end of the material box body, a self-priming pump is installed below the partition, the water inlet of the self-priming pump is connected to a liquid supply pipe, the water outlet of the self-priming pump is connected to a liquid outlet pipe, a sleeve is fixed in the middle of the top of the partition, the outer end of the liquid outlet pipe passes through the partition and is connected to the inside of the sleeve, and a number of branch pipes are fixed on both sides of the sleeve, a number of liquid outlet holes are opened on the surface of the branch pipe, and an inner pipe is provided inside the sleeve, and a number of diversion holes are provided on both sides of the inner pipe. The ultra-high molecular weight polyethylene sheet material distribution structure can make the lubricant more evenly mixed into the material to improve the processing quality of the finished product.

[0005] However, in the actual production process of polyethylene sheets, the main production process is to process polyethylene particles into sheets. The purchased raw material particles are of different shapes and sizes, which is not conducive to high-temperature melting. It is easy to cause small particles to deteriorate due to long heating time, and it is also easy to cause waste of production materials. In addition, the polyethylene material after homogenization is thick and heavy, which is not easy to output, and it is easy to clog the pipeline and cause adhesion. Utility Model Content

[0026] A material grading device for producing ultra-high molecular weight polyethylene sheets, comprising a material grading tank 10 and a grinding mechanism.

[0027] An annular bracket 01 is clamped on the outside of the equalizing tank 10, a booster pump 04 is fixedly connected to the outside of the top of the equalizing tank 10, a discharge port 15 is fixedly connected to the lower side of the outer wall at one end of the equalizing tank 10, and a grinding mechanism is fixedly connected to the upper side of the outer wall at the other end of the equalizing tank 10.

During production, after the operator installs the main structures such as the annular bracket 01 and the equalizing tank 10 in the production workshop, the raw materials of ultra-high molecular weight polyethylene particles are put into the equalizing tank 10. After being processed under the high temperature and high pressure environment of the inner cavity of the equalizing tank 10, the booster pump 04 is driven by high-pressure gas to extrude the molten ultra-high molecular weight polyethylene through the discharge port 15, and then the shaping process is carried out;

[0028] The grinding mechanism includes a feed hopper 02, a sealing cover 03, a grinding box 05, a grinding wheel 06 and a grinding motor 08. The grinding box 05 is fixedly connected to the upper side of the outer wall of the other end of the equalizing tank 10, the feed hopper 02 is fixedly connected to the upper side of the grinding box 05, the sealing cover 03 is fixedly connected to the upper end of the feed hopper 02, the grinding motor 08 is fixedly connected to both sides of the inside of the grinding box 05, and one end of the grinding motor 08 is rotatably connected to the grinding wheel 06. The operator puts a certain amount of ultra-high molecular weight polyethylene particles into the feed hopper 02, closes the sealing cover 03, and the grinding motor 08 in the grinding box 05 starts to drive the grinding wheel 06 to rotate, breaking up larger particles in the raw material to facilitate high-temperature melting inside the equalizing tank 10, thereby improving the efficiency of equalizing the material and ensuring the quality of the finished polyethylene board.

[0029] In this embodiment, preferably, a rotating motor 09 is fixedly connected to the bottom inner side of the equalizing tank 10, one end of the rotating motor 09 is fixedly connected to a rotating rod, and one end of the rotating rod is fixedly connected to a stirring rod 11. After the ultra-high molecular weight polyethylene particles are crushed and ground, they are transported to the inner cavity of the equalizing tank 10 through the bottom pipeline of the grinding box 05. The rotating motor 09 at the bottom of the equalizing tank 10 is started to drive the stirring rod 11 to stir, so that the polyethylene particles of different colors are evenly mixed, thereby avoiding color errors in the produced polyethylene sheets.

[0030] In the present embodiment, preferably, a booster pump 04 is fixedly connected to the outer side of the top of the equalizing tank 10, and an exhaust valve is fixedly connected to the bottom of the booster pump 04, and the exhaust valve is fixedly connected to the equalizing tank 10. When the polyethylene particles inside the inner cavity of the equalizing tank 10 melt into a plastic state, the booster pump 04 draws compressed air from the outside of the equalizing tank 10 and inputs it into the inner cavity through the exhaust valve, so that the pressure inside the equalizing tank 10 increases, and the molten polyethylene is squeezed and output to the assembly line through the discharge port 15.

[0031] In the present embodiment, preferably, a heating plate 010 is fixedly connected to the bottom of the equalizing tank 10 and located on the upper side of the rotating motor 09, an insulating plate 12 is fixedly connected inside the heating plate 010, a fitting block 14 is fixedly connected to one side of the insulating plate 12, and a heating wire 13 is plugged into the insulating plate 12. The heating wire 13 can quickly heat the plate surface to the required temperature. The insulating plate 12, as a non-conductive material, can prevent short circuits, isolate circuits and production equipment, protect equipment and personnel safety, and facilitate processes such as heating plastics and hot pressing molding in industrial production.

[0032] In this embodiment, preferably, one end of the grinding motor 08 is fixedly connected to a driving wheel, a transmission belt is rotatably connected inside the driving wheel, the other end of the transmission belt is fixedly connected to a driven wheel, the driven wheel is fixedly connected to the grinding wheel 06, and when the grinding motor 08 is powered on and rotated, it drives the driving wheel to rotate, and the driving wheel and the driven wheel are connected by a transmission belt, thereby driving the grinding wheel 06 fixedly connected to the driven wheel to rotate and grind polyethylene particles.

[0033] In this embodiment, preferably, a curved baffle 07 is fixedly connected inside the grinding box 05 and located at the bottom of the feed hopper 02. By installing the curved baffle 07 between the grinding wheel 06 and the grinding box 05, the polyethylene particles will not leak through the gap between the grinding box 05 and the grinding wheel 06, which can effectively prevent uneven grinding.

[0034] When the material balancing equipment for producing ultra-high molecular weight polyethylene sheets of this embodiment is used,

[0035] When the ultra-high molecular weight polyethylene raw material is fed and ground, the grinding motor 08 in the grinding box 05 is started, driving the driving wheel to rotate. The driving wheel and the driven wheel are connected by a transmission belt, thereby driving the grinding wheel 06 fixedly connected to the driven wheel to rotate and grind the polyethylene particles, which is convenient for high-temperature melting inside the material balancing tank 10. A curved baffle 07 is installed between the grinding wheel 06 and the grinding box 05, so that the polyethylene particles will not leak from the gap between the grinding box 05 and the grinding wheel 06, which can effectively prevent uneven grinding, improve the efficiency of material balancing, and ensure the quality of the finished polyethylene board.

[0036] During the equalization process, the ultra-high molecular weight polyethylene particles are crushed and ground, and then transported to the inner cavity of the equalization tank 10 through the bottom pipe of the grinding box 05. The rotating motor 09 at the bottom of the equalization tank 10 is started to drive the stirring rod 11 to stir, so that the polyethylene particles of different colors are mixed evenly, thereby avoiding color errors in the produced polyethylene sheets. The high-temperature heating of the heating plate 010 can melt the polyethylene particles into a plastic state and promote the mixing of pigments. The booster pump 04 draws compressed air from the outside of the equalization tank 10 and inputs it into the inner cavity through the exhaust valve, so that the pressure in the equalization tank 10 increases, and the molten polyethylene is squeezed and output to the assembly line through the discharge port 15.
