Description

Technical Field

[0001] The utility model relates to the field of feeding components, in particular to a feeding component for a three-roll mill. Background Art

[0002] The three-roll mill is abbreviated as the three-roller mill, which can be divided into an experimental three-roll mill and a production three-roll mill. The three-roll mill is applicable to the manufacture of slurries such as paints, inks, pigments, plastics, etc. The working principle of the three-roll mill: The three-roll mill achieves the grinding effect through the mutual extrusion of the surfaces of the three horizontal rollers and the friction at different speeds. The three-roll mill is the most effective grinding and dispersing equipment for high-viscosity materials.

[0003] When the three-roll mill grinds a liquid, the liquid is usually slowly added from a hopper. Slowly adding the liquid easily causes precipitation, thereby reducing the uniformity of subsequent collection and the grinding effect.

[0004] To solve the above problems, a feeding component for a three-roll mill is proposed in this application. Content of the Utility Model

[0005] (I) Purpose of the Utility Model

[0006] To solve the technical problems in the background art, the utility model proposes a feeding component for a three-roll mill. The utility model drives an auxiliary extraction mechanism to extract the liquid through a driving motor, and drives a scraping mechanism to mix the liquid, increasing the mixing uniformity, and thus facilitating balanced grinding.

[0007] (II) Technical Solution

[0008] To solve the above problems, the utility model provides a feeding component for a three-roll mill, which includes a barrel with an upward opening, and a driving motor is fixedly installed at the bottom of the barrel;

[0009] An auxiliary extraction mechanism is provided on the driving shaft of the driving motor;

[0010] The auxiliary extraction mechanism is connected with a scraping mechanism for cleaning the inner wall of the barrel.

[0011] Preferably, the auxiliary extraction mechanism includes a rotating pipe and a screw blade. The screw blade is axially connected to the driving shaft of the driving motor. The rotating pipe is fixedly sleeved on the screw blade, and the rotating pipe is rotationally communicated with a leakage pipe through a rotary joint.

[0012] Preferably, a rotating plate is rotatably connected to the leakage pipe through a rotating rod. A round box is fixedly connected to the end of the rotating rod. An opening is formed in the outer periphery of the round box. A partition plate is fixedly installed at the opening, and the partition plates at the same opening form an air inlet channel. A collecting pipe is fixedly sleeved in the middle of the round box, and the collecting pipe is communicated with the air inlet channel.

[0015] The above technical solution of the present utility model has the following beneficial technical effects:

[0016] Add the required grinding solution into the inside of the barrel. When adding the solution to the grinding roller, start the driving motor. The driving motor drives the auger blade and the rotating pipe to rotate. The rotation of the rotating pipe drives the stirring rod to mix the solution, increasing the uniformity. At the same time, the scraping blade scrapes the inner wall of the barrel to reduce the adhesion on the inner wall of the barrel. The rotation of the auger blade extracts the solution to leak out through the leakage pipe and acts on the grinding roller, increasing the uniformity of the solution during grinding. The solution acts on the rotating plate through the leakage pipe to rotate, and the rotation of the rotating plate drives the round box to rotate, so that the partition plate guides the air into the collecting pipe. The air inside the collecting pipe enters the whistle and is discharged. The sounding of the whistle can reflect the material leakage speed. When there is no material, the response stops, playing a reminder role. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0025] As Figure 1-6 shown, a feeding assembly of a three-roll mill proposed by the present utility model includes a barrel 1 with an upward opening, and a drive motor 2 is fixedly installed at the bottom of the barrel 1;

[0026] The drive shaft of the drive motor 2 is provided with an auxiliary extraction mechanism 3;

[0027] The auxiliary extraction mechanism 3 is connected with a scraping mechanism 4 for cleaning the inner wall of the barrel 1.

[0028] In an optional embodiment, the auxiliary extraction mechanism 3 includes a rotating tube 31 and an auger blade 32. The auger blade 32 is axially connected to the drive shaft of the drive motor 2, the rotating tube 31 is fixedly sleeved on the auger blade 32, and the rotating tube 31 is rotationally communicated with a drain tube 33 through a rotary joint.

[0029] Furthermore, the drain tube 33 is fixedly communicated with a liquid discharge housing.

[0030] In an optional embodiment, a rotating plate 35 is rotatably connected to the drain tube 33 through a rotating rod 34. The end of the rotating rod 34 is fixedly connected with a round box 36. An opening is formed on the outer periphery of the round box 36. A partition plate 37 is fixedly installed at the opening, and the partition plate 37 located at the same opening forms an air inlet channel 371. A gas collecting pipe 38 is fixedly sleeved in the middle of the round box 36, and the gas collecting pipe 38 is communicated with the air inlet channel 371. One end of the gas collecting pipe 38 is a closed end, and the other end is fixedly communicated with a whistle 39. The air inlet of the whistle 39 is fixedly communicated with the gas collecting pipe 38.

[0031] It should be noted that one partition plate 37 at the air inlet channel 371 extends outside the opening.

[0032] In an optional embodiment, the scraping mechanism 4 includes a scraping blade 41. One end of the scraping blade 41 is fixedly connected to the auger blade 32 for scraping the inner wall of the barrel 1.

[0033] It should be noted that the scraping blade 41 functions to scrape the inner wall of the barrel 1.

[0034] In an alternative embodiment, the rotating tube 31 is fixedly connected to the scraping blade 41 through the stirring rod 42.

[0036] In the present utility model, the required grinding solution is added into the interior of the barrel 1. When adding the solution to the grinding roller, the driving motor 2 is started. The driving motor 2 drives the auger blade 32 and the rotating tube 31 to rotate. The rotation of the rotating tube 31 drives the stirring rod 42 to mix the solution, increasing the uniformity. At the same time, the scraping blade 41 scrapes the inner wall of the barrel 1 to reduce the adhesion on the inner wall of the barrel 1. The rotation of the auger blade 32 extracts the solution, which leaks out through the leakage tube 33 and acts on the grinding roller, increasing the uniformity of the solution during grinding. The solution acts on the rotating plate 35 through the leakage tube 33 to rotate. The rotation of the rotating plate 35 drives the round box 36 to rotate, so that the partition plate 37 guides air into the gas collecting pipe 38. The air inside the gas collecting pipe 38 enters the whistle 39 and is discharged. The sounding of the whistle 39 can reflect the material leakage speed. When there is no material, the response stops, playing a reminder role.
