Description

Technical Field

[0001] The utility model belongs to the technical field of three-roller grinders, and more specifically relates to a three-roller grinder with an operation safety protection device. Background Art

[0002] Three-roll mill, also known as three-roll mill, is a type of equipment suitable for grinding liquid slurries and pastes such as paints, inks, pigments, plastics, cosmetics, soaps, ceramics, rubber, etc. It achieves the grinding effect through the mutual squeezing and friction of three horizontal rollers at different speeds. It is the most effective grinding and dispersing equipment for high-viscosity materials.

[0003] The three-roller grinder in the prior art lacks a protective device. If foreign objects (such as metal blocks, etc.) enter between the two rollers, the machine needs to be stopped urgently to remove them, otherwise the roller surface or other parts will be squeezed and damaged. In addition, after the grinding operation is completed, the three-roller grinder needs to manually wipe off the material remaining on the surface of the grinding roller. After cleaning, butter needs to be evenly applied to the surface of the grinding roller to prevent rust on the surface of the grinding roller. It needs to be manually cleaned when used again. Since the grinder is in operation when the grinding roller is manually cleaned, manual erasing poses a safety hazard.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a three-roller grinding machine with an operation safety protection device is provided, in order to achieve the purpose of having more practical value. Utility Model Content

[0034] The shield assembly 2 includes triangular fixing bases 201 symmetrically mounted in the middle of the top surface of the three-roll grinder 1. Bolt handles 202 for use with the three-roll grinder 1 are mounted on the two triangular fixing bases 201. Two shielding plates 203 are symmetrically hinged between the two triangular fixing bases 201. Ferromagnetic strips 204 are symmetrically mounted on both sides of the bottom surface of the shielding plates 203. A soft rubber plate 205 is bonded between the two shielding plates 203.

[0035] On it, first, the shield assembly 2 is fixedly installed as a whole on the middle of the top surface of the three-roll mill 1 through the bolt handle 202 on the triangular fixing seat 201, and the ferromagnetic strip 204 on the bottom surface of the shield plate 203 is magnetically attracted to the top surface of the three-roll mill 1.

[0036] As attached Figure 1 To the attached Figure 6 As shown, in some embodiments, the adjustment assembly 3 includes a hinged joint 301 mounted on the bottom surface of the shield 203 and a threaded through hole provided in the middle of the shield 203. An adjustment rod 303 is slidably provided in the threaded through hole. A connecting rod 302 is rotatably provided on the hinged joint 301. A sliding groove is provided in the middle of the connecting rod 302 to match the adjustment rod 303.

[0037] The adjusting rod 303 includes a T-shaped round rod 3031. The outer surface of the upper end of the T-shaped round rod 3031 is provided with an upper thread 3032 for matching the threaded through hole. The outer surface of the lower end of the T-shaped round rod 3031 is provided with a lower thread 3033 identical to the upper thread 3032. A T-shaped sliding rod 3035 is rotatably provided on the bottom surface of the T-shaped round rod 3031. A rotating head 3034 is rotatably provided in the inner cavity of the upper end of the T-shaped sliding rod 3035. The upper end of the rotating head 3034 is fixedly connected to the middle part of the bottom surface of the lower thread 3033. The lower end of the T-shaped sliding rod 3035 is slidably provided in the sliding groove of the connecting rod 302.

[0038] On it, rotate the T-shaped round rod 3031 so that the lower thread 3033 at the lower end of the T-shaped round rod 3031 disengages from the threaded through hole of the shield plate 203, and then the T-shaped round rod 3031 slides downward, and the T-shaped sliding rod 3035 slides backward in the sliding groove of the connecting rod 302, so that the arc-shaped groove plate 401 at the other end of the connecting rod 302 rotates downward about the axis of the hinge joint 301.

[0039] As attached Figure 1 To the attached Figure 6As shown, in some embodiments, the cleaning assembly 4 includes an arcuate slot plate 401 fixedly connected to one end of the connecting rod 302 at the middle portion of one side, a bolt 404 is provided on the bottom surface of the arcuate slot plate 401, a bolt hole 403 is provided in the middle portion of the outer wall surface on the same side of the arcuate slot plate 401 and the bolt 404, and a bolt 404 is installed between the two bolt holes 403;

[0040] On it, the arc groove plate rotates downward, so that the arc block 402 on the bottom surface of the arc groove plate 401 contacts the surface of the grinding roller of the three-roll grinder 1. Further, by rotating the T-shaped round rod 3031, the upper thread 3032 on the T-shaped round rod 3031 enters the threaded through hole. As the T-shaped round rod 3031 rotates, the arc block 402 is driven to closely contact the surface of the grinding roller.

[0041] As attached Figure 1 To the attached Figure 6 As shown, in some embodiments, the outer wall surface of the arc block 402 is bonded with sponge;

[0042] The three-roller grinder 1 is started to rotate the grinding roller, and the sponge on the surface of the arc block 402 wipes off the grease on the surface of the grinding roller, and then the T-shaped round rod 3031 is rotated in the opposite direction to reset the adjustment component 3 and the cleaning component 4. At this time, the shield 203 is lifted and the bolt 404 is rotated to separate the arc block 402 from the bottom surface of the arc groove plate 401, and then a new arc block 402 is replaced.

[0043] The specific usage and function of this embodiment are as follows: first, the shield assembly 2 is fixedly installed on the middle of the top surface of the three-roll grinder 1 through the bolt handle 202 on the triangular fixing seat 201, and the ferromagnetic strip 204 on the bottom surface of the shield plate 203 is magnetically attracted to the top surface of the three-roll grinder 1, and the T-shaped round rod 3031 is further rotated so that the lower thread 3033 at the lower end of the T-shaped round rod 3031 is disengaged from the threaded through hole of the shield plate 203, and then the T-shaped round rod 3031 slides downward, and the T-shaped sliding rod 3035 slides backward in the sliding groove of the connecting rod 302, so that the arc groove plate 401 at the other end of the connecting rod 302 rotates downward about the axis of the hinge joint 301, so that the arc groove plate 401 The arc block 402 on the bottom surface contacts the surface of the grinding roller of the three-roll grinder 1. Further, by rotating the T-shaped round rod 3031, the upper thread 3032 on the T-shaped round rod 3031 enters the threaded through hole. As the T-shaped round rod 3031 rotates, the arc block 402 is driven to closely contact the surface of the grinding roller, and then the three-roll grinder 1 is started to rotate the grinding roller. The sponge on the surface of the arc block 402 wipes the grease on the surface of the grinding roller. Then, the T-shaped round rod 3031 is rotated in the opposite direction to reset the adjustment component 3 and the cleaning component 4. At this time, the shield 203 is lifted and the bolt 404 is rotated to separate the arc block 402 from the bottom surface of the arc slot plate 401, and a new arc block 402 is replaced.

[0044] Further lift the shield plate 203 at the feeding end, put the material between the two grinding rollers at this end and reset the shield plate 203 for grinding, thereby preventing foreign matter from falling between the two grinding rollers, effectively preventing foreign matter from entering, and better coordinating the safe operation of the grinding rollers. After the grinding is completed, the grinding rollers are cleaned again in the above manner without manual cleaning, avoiding the potential safety hazards caused by manual cleaning during the operation of the three-roller grinder 1.
