Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment, and in particular to a fully automatic grease replenishment device for a three-roll mill for grease processing. Background Technology

[0002] The fully automatic grease replenishment device for three-roll mills in grease processing refers to an automated feeding device specifically designed for three-roll mills in grease production. Through mechanical structure and automatic control, it can accurately and continuously replenish grease raw materials to the mill, replacing manual operation. It can adapt to high-viscosity materials, reduce clogging, scrape off residues on the barrel wall to improve raw material utilization, and can also automatically position the turnover barrel to solve problems such as uneven feeding and alignment errors, thereby improving production efficiency and stability.

[0003] When manually adding grease, the container filled with grease must first be manually moved to the side of the three-roll mill. After manually aligning it with the filling port, the material in the container is scooped or pushed to the feed port of the mill with the help of tools. During the process, grease needs to be added frequently to maintain the supply. At the same time, the position of the container needs to be constantly adjusted to avoid leakage. After completion, the residue on the container wall and the work site need to be cleaned.

[0004] The existing technology has the following drawbacks: traditional manual grease filling or simple conveying equipment often faces problems such as poor material flow and poor conveying, which can easily cause pipeline blockage, requiring frequent shutdowns for cleaning and reducing production efficiency. At the same time, a large amount of material is easily left on the inner wall of the raw material turnover bucket, which is difficult to clean thoroughly by manual dumping, resulting in low raw material utilization and increased production costs. To address these issues, a fully automatic grease filling device for a three-roll mill for lubricating grease processing is proposed. Utility Model Content

A guide rod 9 is connected to the bottom of the guide rod 9, and a pressure plate 3 is fixedly connected to the bottom of the pressure plate 3. A sealing ring 4 is fixedly connected to the outer wall of the pressure plate 3. When the sealing ring 4 moves downward with the pressure plate 3, it can ensure that the pressure plate 3 and the turnover drum 11 are in a sealed state to prevent grease from overflowing. The turnover drum 11 is placed on the top of the base plate 1. A rotating mechanism is provided at the output end of the speed-regulating motor 5. A movable component is provided at the top of the base plate 1. The rotating mechanism includes a coupling sleeve 6, which is fixedly connected to the output end of the speed-regulating motor 5. A screw pump 13 is fixedly connected to the bottom of the coupling sleeve 6. The screw pump 13 is a positive displacement pump that realizes liquid suction and discharge through the rotation of the screw. The coupling sleeve 6 is fixedly connected to the screw in the screw pump 13. A grease outlet pipe 12 is fixedly connected to the outer wall of the screw pump 13. The grease outlet pipe 12 is a grease output pipe. The other end of the grease outlet pipe 12 can be placed on the discharge port of the three-roll mill.

[0029] Reference Figures 1-3 The active components include a slider 14, which is slidably connected to the top of the base plate 1. The base plate 1 has a slot corresponding to the slider 14, allowing the slider 14 to move left and right. The inner wall of the slider 14 has an extrusion groove 16, and a long rod 17 is slidably connected to the inner wall of the extrusion groove 16. A round rod is provided inside the long rod 17, which is slidably connected to the inner wall of the extrusion groove 16. A baffle 15 is fixedly connected to the top of the base plate 1. The long rod 17 is fixedly connected to the outer wall of the cylinder rod 10. The side wall of the slider 14 contacts the outer wall of the turnover bucket 11, and the slider 14 positions the turnover bucket 11 to ensure that the turnover bucket 11 is directly below the pressure plate 3. The outer wall of the baffle 15 contacts the outer wall of the turnover bucket 11, and the baffle 15 can limit the placement position of the turnover bucket 11. The upper part of the extrusion groove 16 is inclined.

[0030] Reference Figures 2-4The screw pump 13 is fixedly connected to the bottom end of the fixed rod 8 and the top end of the pressure plate 3. The outer shell of the screw pump 13 is fixedly connected to the fixed rod 8 and the pressure plate 3 respectively. The outer wall of the sealing ring 4 is in contact with the inner wall of the turnover drum 11.

[0031] Working principle: When the three-roll mill needs to be replenished, first place the turnover drum 11 filled with raw materials on the base plate 1, so that the turnover drum 11 contacts the baffle 15. Then, the pushing device is moved to the side of the three-roll mill. Subsequently, the electric cylinder 2 is used to move the cylinder rod 10, the fixed rod 8, the guide rod 9, the pressure plate 3, and the sealing ring 4 downward. At the same time, the speed regulating motor 5 is turned on. When the cylinder rod 10 moves downward with the long rod 17, the long rod 17 will squeeze the inclined section of the extrusion groove 16 on the slider 14, so that the two sets of sliders 14 move closer to each other. When the slider 14 contacts the turnover drum 11, The two sets of sliders 14 will squeeze the turnover drum 11, causing the turnover drum 11 to move to a position directly below the pressure plate 3. When the pressure plate 3 comes into contact with the raw material, the long rod 17 enters the vertical section of the extrusion groove 16 and does not squeeze the sliders 14. At the same time, the sliders 14 will position the turnover drum 11. As the pressure plate 3 moves downward, the pressure plate 3 will continuously pressurize the material in the drum. In conjunction with the screw pump 13, the grease in the turnover drum 11 will be extracted. The extracted material will be transported to the discharge port of the three-roll mill through the grease outlet pipe 12. At the same time, the sealing ring 4 can scrape off the residual grease on the drum wall when it descends, improving the utilization rate of raw materials.

[0032] When the grease delivery is complete, the electric cylinder 2 moves the cylinder rod 10 upward. The cylinder rod 10 will move the bracket 7, pressure plate 3, fixing rod 8 and screw pump 13 to the initial position. When the long rod 17 moves upward with the cylinder rod 10, the long rod 17 enters the inclined section of the extrusion groove 16 and squeezes the two sets of sliders 14 to separate from each other, releasing the positioning of the turnover bucket 11. When the cylinder rod 10 moves to the initial position, the operator can replace the turnover bucket 11 and continue to repeat the above operation to replenish grease.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
