Description

Technical Field

[0001] The utility model relates to a three-roller grinding device, belonging to the field of grease grinding. Background Art

[0002] The three-roll mill is a commonly used device for grease grinding. Grease is first fed into the widest gap between the three rollers. As the grease gradually passes through the gap between the three closely spaced rollers, it is subjected to strong shear forces and compression each time it passes between two adjacent rollers. The three-roll mill is equipped with an inclined drain chute. After grinding, the grease drains through the chute into a collection container below the chute. When the collection container is full and removed, some grease may drip from the drain chute onto the ground due to its viscosity, causing contamination and requiring cleaning of the ground and other areas. Therefore, a three-roll milling device is needed to prevent this uncontrolled dripping of grease. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a three-roll grinding device to solve the problems raised in the above background technology. The utility model prevents residual oil from dripping randomly from the oil drain tank.

[0011] Beneficial effects of the utility model:

[0012] 1. Insert the plug-in strip into the plug-in slot to connect the oil collecting box to the casing. Push the oil collecting box along the guide rail to move it directly under the oil drain tank or to one side of the oil drain tank, so that the oil collecting box and the collection container are alternately placed under the oil drain tank, thereby not affecting the collection container being placed directly under the oil drain tank.

[0013] 2. Move the oil collecting box to the bottom of the oil drain trough, and then remove the collection container on the lower side of the oil drain trough. The grease dripping from the oil drain trough will drip into the oil collecting box, thereby preventing the grease from dripping randomly on the ground and other areas.

[0014] 3. When using screws to install the guide rail on the casing, make the connecting plate at one end of the guide rail fit with the pad, and then use screws to connect the pad and the connecting plate. On the one hand, it increases the connection range between the guide rail and the casing and improves the stability of the structure. On the other hand, the pad locally increases the thickness of the casing installation screw part without increasing the overall wall thickness of the casing.

[0015] 4. Insert the T-bar with screw holes into the T-slot on the pad to connect the T-bar and the pad. Pass the screws through the holes and screw them into the screw holes to complete the assembly of the strip and the connecting plate. When the screw holes are damaged due to excessive torque or other reasons, pull out the T-bar and replace it.

[0016] 5. When moving the oil collecting box, the oil collecting box drives the support wheels to roll along the ground through the support legs and U-shaped frame, thereby lifting the oil collecting box, improving the stability of the oil collecting box installation, and preventing the weight of the oil collecting box from acting entirely on the connection between the plug-in strip and the guide rail.
