Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of open mills, and in particular to a cooling device for the pressure rollers of an open mill. Background Technology
[0002] An open mixing mill is a rubber processing machine with exposed pressure rollers used in rubber factories to plasticize, mix raw rubber, or perform hot refining and molding of mixed rubber. Open mixing mills have a simple structure, are relatively easy to manufacture, easy to operate, and convenient to maintain and disassemble, so they are widely used in rubber and plastic product enterprises.
[0003] Existing cooling devices for open mill pressure rollers, such as the high-efficiency cooling device for open mill pressure rollers disclosed in utility model patent application number 202222835987.1, mainly include a water storage tank and a pressure roller. Mounting box one and mounting box two are fixedly installed above the water storage tank. The pressure roller is rotatably connected between mounting box one and mounting box two. The interior of the pressure roller is hollow, forming a receiving cavity. The ends of the pressure roller located inside mounting box two are rotatably connected to a U-shaped water outlet pipe and a U-shaped water inlet pipe, respectively. In use, cooling water is input through the straight-line water inlet pipe. A water pump draws water from the water storage cavity one and pumps it through the U-shaped water inlet pipe into the interior of one of the pressure rollers. Then, it is input into the interior of the other pressure roller through a U-shaped connecting pipe, and finally output through the U-shaped water outlet pipe to the interior of the water storage cavity two.
[0004] However, most existing cooling water is directly delivered into the pressure roller, resulting in uneven flow rate of the cooling water inside the pressure roller and large local temperature differences in the roller body. Moreover, the returned cooling water needs to be cooled naturally for a long time, which leads to excessively large water storage tank volume and waste of water resources. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a cooling device for open mill pressure rollers that not only uses spiral blades to evenly distribute and flow cooling water inside the pressure roller to avoid excessive temperature difference in the roller body, but also cools the cooling water, facilitates the recycling of cooling water, and saves water resources.

The water storage mechanism is installed on the cold pressing mechanism to store cooling water. The water delivery mechanism is installed on the cold pressing mechanism to deliver cooling water into the cold pressing mechanism. The heat dissipation mechanism is installed on the cold pressing mechanism to facilitate heat dissipation of the cooling water. The return mechanism is installed on the heat dissipation mechanism to return the cooling water to the water storage mechanism. When the operator adds sufficient cooling water to the water storage mechanism, the water delivery mechanism is started, which delivers the cooling water from the water storage mechanism to the cold pressing mechanism. The cold pressing mechanism performs cold pressing on the rubber, and the cooling water in the cold pressing mechanism is delivered to the heat dissipation mechanism to dissipate heat and cool down the cooling water.

When the first water pump is started, the first water pump draws cooling water out of the water tank through the first pumping pipe and delivers the cooling water to the multiple connecting sleeves through the delivery pipe and the multi-component water pipe.
[0010] Preferably, the heat dissipation mechanism includes a collection box, a heat dissipation tank, a crossbeam, and two sets of cooling fans. The collection box is installed on the workbench and communicates with the interior of multiple sets of connecting sleeves. The top of the heat dissipation tank communicates with the interior of the bottom of the collection box. The crossbeam is installed on the workbench, and both sets of cooling fans are installed on the crossbeam. The collection box collects the cooling water flowing out from the multiple sets of connecting sleeves. The cooling water is centrally transported to the heat dissipation tank for heat dissipation. The two sets of cooling fans are activated, and the two sets of cooling fans accelerate the airflow on the surface of the heat dissipation tank, thereby accelerating the cooling of the cooling water in the heat dissipation tank.
[0011] Preferably, the heat sink is a finned heat sink with a graphene coating on the fin surface; graphene has an extremely high thermal conductivity, which can significantly improve the heat conduction capacity of the fin surface and enhance the heat dissipation effect of the heat sink.
