Description

Technical Field

[0001] The utility model relates to the technical field of material grinding, in particular to a resin production and processing grinding device. Background Art

[0002] Resin usually refers to an organic polymer that softens or melts when heated, tends to flow under the action of external force when softened, and is solid, semi-solid, or sometimes liquid at room temperature. In a broad sense, any polymer compound that can be used as a raw material for plastic product processing is called a resin. In order to ensure the production and processing efficiency of the resin, the raw materials need to be ground and refined before processing to promote the mixing and uniform fusion of multiple types of raw materials. At present, the grinding of raw materials is mainly carried out by grinding machines. However, the existing grinders have a slow rotation speed and low processing efficiency when actually used.

[0003] The Chinese patent with the authorization announcement number CN210332789U discloses a phenolic resin production and processing grinding equipment, including a grinding barrel, a hollow grinding roller and a grinding mechanism, a feeding device is installed on the top of the grinding barrel, a hollow grinding roller is welded to the inner wall of the grinding barrel through a connecting rod, a grinding mechanism is arranged in the hollow grinding roller, a receiving funnel is welded to the bottom end of the hollow grinding roller, a filtering device is also arranged on the inner wall of the grinding barrel, a reciprocating device is connected to one side of the filtering device, and the rotating motor of the reciprocating device is arranged on the outside of the grinding barrel, the lower half of the grinding barrel is arranged in a funnel shape, four groups of supporting legs arranged in a circular array are welded to the bottom end of the grinding barrel, and a discharge pipe with a solenoid valve is also connected to the bottom end of the grinding barrel. The phenolic resin production and processing grinding equipment not only combines grinding and filtering into one, but also filters thoroughly and quickly, and is suitable for large-scale popularization and promotion.

[0004] However, the device still has some shortcomings: if the grinding roller in the device is in a high-speed rotation and grinding state for a long time, its surface temperature will become higher and higher. When the temperature of the grinding roller exceeds a certain value, the raw material is easy to melt under high temperature conditions, thereby affecting the subsequent grinding efficiency. Therefore, the rotation speed of the grinding roller of the grinding equipment is usually very low, and the grinding efficiency is low, which needs to be improved. Utility Model Content

[0016] By arranging a cooling groove in the guide seat, a spiral groove in the grinding roller, and a cooling box and a liquid pump on the frame, a low-temperature cooling medium is circulated and injected into the cooling groove and the spiral groove through the liquid pump, so that the temperature of the guide seat and the grinding roller is quickly reduced, preventing the guide seat and the grinding roller from generating high temperature due to long-term operation, thereby preventing the raw material from melting during the grinding process. This cooling structure enables the entire device to maintain long-term high-speed grinding operation, with high stability and long service life. BRIEF DESCRIPTION OF THE DRAWINGS

A grinding barrel 2 is provided in the frame 1, a feed hopper 3 is provided on the frame 1, a feed pipe 4 connecting the feed hopper 3 with the grinding barrel 2 is provided at the bottom of the feed hopper 3, and a discharge pipe 5 connecting the inside of the grinding barrel 2 is provided at the bottom of the grinding barrel 2. A guide seat 6 is provided in the grinding barrel 2, a grinding roller 8 with a clearance fit is provided on the inner side of the guide seat 6, a rotating shaft 9 is integrally provided on the grinding roller 8, and a motor A10 for driving the rotating shaft 9 to rotate is provided on the frame 1. A small gear is provided on the rotating shaft 9, and a large gear is provided on the frame 1, the small gear is meshed and connected with the large gear, and the motor A10 drives and connects the large gear.

[0025] The cooling box 11 is arranged on the frame 1, and a return pipe 12 is arranged on the cooling box 11 and communicated with the interior thereof. The other end of the return pipe 12 is inserted into the guide seat 6 and communicated with the interior thereof. A branch pipe A13 is arranged on the return pipe 12 and communicated with the interior thereof. The other end of the branch pipe A13 is inserted into the interior of the rotating shaft 9 along the bottom thereof and communicated with the interior of the grinding roller 8. The liquid pump 14 is arranged on the frame 1, and a material extraction pipe of the liquid pump 14 is inserted into the cooling box 11 and is located below the liquid surface. A liquid outlet pipe 15 is arranged at the output end of the liquid pump 14, and the other end of the liquid outlet pipe 15 is inserted into the interior of the rotating shaft 9 along the top thereof and communicated with the interior of the grinding roller 8. A branch pipe B16 is arranged on the liquid outlet pipe 15 and communicated with the interior thereof. The other end of the branch pipe B16 is inserted into the guide seat 6 and communicated with the interior thereof. A conical guide groove is arranged at the top of the guide seat 6, and a cooling groove 601 is arranged in the guide seat 6. The branch pipe B16 is inserted into the cooling groove 601, and the return pipe 12 is inserted into the cooling groove 601. A spiral plate 7 is arranged in the cooling groove 601 to form a spiral channel in the cooling groove, and the discharge port of the branch pipe B16 and the feed port of the reflux pipe 12 are respectively connected to one end of the corresponding side of the spiral channel. A spiral groove 801 is arranged in the grinding roller 8, and an upper cavity and a lower cavity are arranged in the rotating shaft 9. The upper end opening of the spiral groove 801 and the liquid outlet pipe 15 are both connected to the interior of the upper cavity, and the lower end opening of the spiral groove 801 and the branch pipe A13 are both connected to the lower cavity.

[0026] In this embodiment, the raw material is put into the feed hopper 3, and the raw material gradually enters the grinding barrel 2 along the discharge pipe 4, and the motor A10 is started. The motor A10 drives the grinding roller 8 to rotate, and the grinding roller 8 is used to grind the raw material in cooperation with the guide seat 6, and the obtained material is discharged along the discharge pipe 5. As the grinding time increases, the temperature of the guide seat 6 and the grinding roller 8 becomes higher and higher. At this time, the cooling system intervenes, and the refrigeration parts in the cooling box 11 react quickly to quickly cool down the cooling medium therein. The liquid pump 14 extracts the low-temperature cooling medium and injects it into the cooling groove 601 of the guide seat 6 and the spiral groove 801 of the grinding roller 8. The low-temperature cooling medium exchanges heat with the high-temperature guide seat 6 and the grinding roller 8, and the temperature of the guide seat 6 and the grinding roller 8 is quickly reduced to prevent the raw material from melting. Then the high-temperature medium refluxes into the cooling box 11 along the branch pipe A13 and the reflux pipe 12. Such a cycle cools the guide seat 6 and the grinding roller 8, which can keep the temperature of the grinding roller 8 within the standard under the state of long-term high-speed rotation, thereby improving the grinding efficiency of the raw material.

[0029] In this embodiment, before the raw materials enter the grinding barrel 2, the large pieces of materials are first crushed to reduce the volume of the raw materials entering the grinding barrel 2, which is convenient for grinding and thus improves the grinding efficiency.
