Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present invention, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
Referring to fig. 1-5, a batch-type feeding-based pigment particle grinding device is provided, which comprises a base 100, a grinding barrel 110 and a side plate 101, wherein the grinding barrel 110 and the side plate 101 are arranged at the top of the base 100, the top end of the side plate 101 bends towards one side of the grinding barrel 110, a driving device 102 is fixedly arranged at the bottom of the bending end, the driving device 102 is preferably a motor, and the output end of the driving device 102 is connected with a stirring rod 103 extending into the grinding barrel 110. Simultaneously, screw blade 104 is also fixedly connected with stirring rod 103. During grinding, the pigment is poured into the grinding barrel 110, then a barrel cover (not shown in the figure) can be covered on the top of the grinding barrel 110, and then the driving device 102 drives the spiral blade 104 to rotate through the stirring rod 103, and the rotating spiral blade 104 cuts the pigment particles at the moment, so that the grinding of the pigment is realized.
However, when a large amount of coloring material needs to be ground at a time, the manner of adding all the coloring material at a time may cause the coloring material in the grinding barrel 110 to be excessively large, thereby reducing the grinding efficiency of the coloring material. If the mode of multiple feeding is adopted, the grinding work can be frequently started and closed, and the grinding efficiency can be influenced. For this purpose, in fig. 2, a drainage tube 120 is disposed at the bottom of the grinding barrel 110 and located at the outer periphery of the spiral blade 104, a carrier 130 is disposed above the drainage tube 120 in the grinding barrel 110, and the carrier 130 divides the grinding barrel 110 into a grinding chamber and a temporary storage chamber; the grinding chamber is positioned below the bearing piece, and the temporary storage chamber is positioned above the bearing piece; when the carrier 130 moves down to a certain height, a discharge opening is formed between the carrier 130 and the inner wall of the grinding barrel 110 for the colorant to pass through, so that the colorant in the temporary storage chamber above the carrier 130 can fall into the grinding chamber through the discharge opening.
During grinding, the spiral blade 104 in a rotating state is matched with the drainage cylinder 120 to push the pigment upwards, the bearing part vertically reciprocates in the grinding barrel 110 by utilizing the rotating force of the stirring rod 103, and shunts the pigment pushed in the grinding chamber to the temporary storage chamber during upward movement, and the shunted pigment is discharged into the grinding chamber through the discharge opening during downward movement.
That is, the carrier moves up and down in the grinding barrel 110, and transfers part of the pigment from the grinding chamber to the temporary storage chamber during the movement, and then transfers the pigment from the temporary storage chamber to the grinding chamber, thereby reducing the quantity of the pigment in the grinding chamber during the transfer, and improving the grinding efficiency of the pigment.
In embodiment 1, as shown in fig. 2, a drainage tube 120 is fixedly disposed on the inner wall of the bottom of the grinding barrel 110, and a through hole 121 is formed in the bottom of the drainage tube 120. In this way, the rotating helical blade 104 pushes the colorant in the grinding drum 110 upward, so that the drainage cavity 122 is formed in the drainage drum 120. Then, the pushed color material is limited by the tubular structure of the drainage tube 120, so that the color material cannot diffuse outwards and can only move upwards along the drainage tube 120, and at this time, negative pressure is generated at the bottom of the drainage tube 120 (see arrow direction in fig. 4), so that the color material outside the grinding barrel 110 is sucked into the drainage cavity 122 through the through hole 121, and a circulation is formed.
The colorant may be directly milled into particles, or may be mixed with a solvent to mill the colorant particles into a fluid state, both of which are milling of the colorant. The grinding apparatus of the present invention can thus also, but is not limited to, grinding both ways.
Furthermore, fig. 2 also shows a specific structure of the carrier, the vertical reciprocation of the carrier and the discharge opening. As shown in the figure:
first, the carrier 130 is hollow and circular, the hollow inner diameter of the carrier 130 matches with the outer diameter of the drainage tube 120, the outer edge of the carrier 130 cooperates with the inner wall of the grinding barrel 110 to divide the interior of the grinding barrel 110 into an upper chamber and a lower chamber, the chamber above the carrier 130 is a temporary storage chamber, and the chamber below the carrier 130 is a grinding chamber. In addition, the middle position of the top of the bearing member 130 is provided with a convex ring 131 protruding upwards, and the convex ring 131 can block the pigment at the top of the bearing member 130, so that the pigment at the top of the bearing member 130 is prevented from falling to the hollow part of the bearing member 130 through the inner ring of the bearing member 130.
Secondly, the specific structure of the vertical reciprocating motion of the bearing member is that a first nut 140 is fixedly arranged on the inner ring of the bearing member 130, and a first reciprocating groove 141 for guiding the first nut 140 to vertically reciprocate, wherein the first reciprocating groove 141 is arranged on the outer ring of the stirring rod 103, and the first nut 140 is sleeved on the outer ring of the stirring rod 103 and is in threaded connection with the first reciprocating groove 141. In the above embodiment, the first nut 140 is fixedly connected to the inner ring of the bearing 130 through a connecting rod.
Finally, the inner wall of the grinding barrel 110 is provided with a plurality of ribs 132, and the outer edge of the bearing piece 130 is provided with grooves 133 matched with the ribs 132; therefore, when the carrier 130 moves up, the carrier 130 is always in the state of being attached to the ribs 132, and when the carrier 130 moves down, the carrier 130 is separated from the ribs 132, and a discharge opening for the colorant to pass through is formed between the two, so that the colorant at the top of the carrier 130 can fall into the grinding chamber through the discharge opening to participate in the subsequent grinding work.
The ribs 132 are vertically disposed along the inner wall of the grinding barrel 110, the ribs 132 include a first rib 132a and a second rib 132b, the upper end surface of the first rib 132a is flush with the upper edge of the grinding barrel 110, the lower end surface extends to a height half of the inner wall of the grinding barrel 110, the lower end surface is not in contact with the bottom of the grinding barrel 110, and when the carrier 130 moves upwards, the carrier 130 and the ribs 132 are in a fitting state; when the carrier 130 moves down, the carrier 130 is separated from the first rib 132a, and the groove 133 at the outer edge of the carrier 130 becomes a discharge opening for the colorant to pass through, so that the colorant in the temporary storage chamber above the carrier 130 can fall into the grinding chamber through the discharge opening. It should be noted that, the bottom surface of the first rib 132a is higher than the bottom surface of the second rib 132b, and after the carrier 130 is separated from the first rib 132a, the carrier 130 can also reciprocate vertically along the second rib 132b, so that the carrier 130 reciprocates along the first reciprocation groove 141 more smoothly.
On the other hand, the upper surface of the carrier 130 is an inclined surface, and the inclined upper surface gradually slopes downward from the outer side of the convex ring 131 to the outer edge of the carrier 130, i.e. the upper surface gradually slopes downward from the inner ring to the outer ring, so as to avoid unsmooth discharging caused by the fact that the pigment stays at the top of the carrier 130.
In addition, in order to improve the efficiency of pushing the pigment upwards, in this embodiment, the fan blades 105 are fixedly disposed on the outer ring of the stirring rod 103, and the fan blades 105 are located in the drainage cavity 122, so that when the fan blades 105 rotate in the drainage cavity 122, the pigment is pushed upwards by the fan blades 105. The fan blade 105 is arranged above the spiral blade 104, and the through hole 121 is arranged on the outer side of the spiral blade 104 in a surrounding manner. By rotating the spiral blade 104 and the fan blade 105, the coloring material outside the through hole 121 is guided to the spiral blade 104 for grinding, and the grinded coloring material is pushed upwards. The outside of drainage tube 120 is equipped with a plurality of first filtration pore 123, the outside of the high drainage tube 120 of first filtration pore 123 setting between screw blade 104 and flabellum 105, through the inside negative pressure that forms of drainage tube 120, the part pigment that has ground to pass first filtration pore 123 reaches in the drainage tube 120, upwards promote by screw blade 104 and flabellum 105, do not need to pass through the grinding of screw blade 104 anymore, directly upward move in the drainage tube 120 and reach the temporary storage room, in this way, the pigment through screw blade 104 reduces, when guaranteeing the good grinding effect of grinding equipment, the grinding burden of screw blade 104 has been alleviateed.
Further, a diverter cover 160 is fixedly disposed on top of the inner ring of the carrier 130, and a plurality of second filter holes 161 are formed in the outer ring of the diverter cover 160. In this way, as shown in fig. 4, after the pushed pigment impinges on the inner ring of the diversion cover 160, the pigment conforming to the aperture of the filtering hole enters the top of the bearing member 130 through the filtering hole, and the pigment not conforming to the aperture collides with the diversion cover 160 to form a turbulence, and falls into the grinding chamber, the pigment in the drainage tube 120 collides with the inner side of the drainage tube 120 to form a turbulence, and part of the pigment not conforming to the aperture reaches the screw blade 104 again to continue grinding under the turbulence effect of the pigment. During the upward movement of the carrier 130, the carrier 130 is separated from the drainage tube 120, so that the acting force of the spiral blade 104 and the fan blade 105 on the upward pushing of the pigment in the diversion cover 160 is reduced, and part of the pigment which does not meet the aperture can fall to be converged with the pigment outside the drainage tube 120, and then reaches the spiral blade 104 again for continuous grinding.
That is, the carrier 130 not only can play a role in diverting, but also can be matched with the diverting cover 160 in the process of pushing the pigment, so that only the pigment conforming to the aperture of the filtering hole enters the top of the carrier 130 through the filtering hole, and the effect of screening the pigment is achieved, thereby realizing that the pigment which is not ground is always in a grinding state while diverting.
Further, a conical sealing ring 124 is arranged on the top outer side of the drainage tube 120, and the bottom of the bearing member 130 is matched with the sealing ring 124. The conical sealing ring 124 has guiding and sealing functions, and certain manufacturing errors can exist in the production process of the stirring rod 103 and the bearing piece 130, and the conical outer side of the sealing ring 124 guides the movement of the bearing piece 130, so that the situation that the bearing piece 130 cannot move downwards to the position where the discharge opening is opened due to the manufacturing errors is avoided; when the carrier 130 moves down to the position where the discharge port is opened, the sealing ring 124 seals the matching position of the carrier 130 and the drainage tube 120, so as to avoid the situation that the ground pigment leaks out of the gap between the carrier 130 and the drainage tube 120 to the outside of the drainage tube 120 and part of the pigment is qualified to be repeatedly ground.
The working principle of this embodiment, as shown in connection with fig. 4, is as follows:
the driving device 102 drives the stirring rod 103 to rotate through the stirring rod 103, and the rotating spiral blade 104 pushes the pigment in the grinding barrel 110 upwards, so that a drainage cavity 122 is formed in the drainage barrel 120. Then, the pushed pigment is limited by the tubular structure of the drainage tube 120, so that the pigment cannot diffuse outwards and can only move upwards along the drainage tube 120, and at this time, negative pressure is generated at the bottom of the drainage tube 120 (refer to the arrow direction in fig. 4), so that the pigment outside the grinding barrel 110 is sucked into the drainage cavity 122 through the through hole 121 to form a circulation; meanwhile, the rotation of the stirring rod 103 also drives the first reciprocating groove 141 to rotate, the first reciprocating groove 141 rotates to drive the first nut 140 to vertically reciprocate, and the first nut 140 drives the carrier 130 to vertically reciprocate. The vertical reciprocation of the carrier 130 produces two states:
when moving downwards, the bearing piece 130 is separated from the first convex rib 132a, and a discharge opening for the pigment to pass through is formed between the bearing piece 130 and the first convex rib, so that the pigment at the top of the bearing piece 130 can fall into the grinding chamber through the discharge opening;
when the toner is moved up, the toner pushed in the drainage cavity 122 moves to the upper part of the bearing member 130 through the inner ring of the bearing member 130, and when the gravity of the toner overcomes the pushing force, the toner falls to the top of the bearing member 130. Along with the gradual upward movement of the bearing member 130, the bearing member 130 is in a state of being attached to the convex rib 132, at this time, the discharge opening is blocked, and a part of the pigment is positioned at the top of the temporary storage chamber, so that the distribution of the pigment in the grinding chamber is realized.
Wherein, the pigment which is grinded and does not accord with the aperture of the second filtering hole 161 is pushed to impact on the inner ring of the diversion cover 160, falls into the grinding chamber and is continuously grinded. The toner ground to fit the aperture of the second filter hole 161 enters the top of the carrier 130 through the second filter hole 161. The colorant at the top of the carrier 130, which accords with the aperture of the second filtering hole 161, falls into the grinding chamber along with the downward movement of the carrier 130, and directly passes through the first filtering hole 123 to reach the temporary storage chamber, so that the grinding burden of the spiral blade 104 is reduced.
Example 2 this example provides another embodiment of the discharge opening. As shown in fig. 6:
the discharge opening is an expansion part 150 that expands outwards from the outer ring of the grinding barrel 110, that is, when the bearing member 130 does not move to the expansion part 150, the bearing member 130 is attached to the outer ring of the grinding barrel 110, the pigment at the top of the bearing member 130 cannot fall down, and when the bearing member 130 moves down to the expansion part 150, a discharge channel is formed between the outer ring of the bearing member 130 and the expansion part 150 and is used for allowing the pigment at the top of the bearing member 130 to fall into the grinding chamber, and at the moment, the pigment at the top of the bearing member 130 falls into the grinding chamber through discharge, so that intermittent discharge of pigment particles is realized.
In summary, the intermittent feeding-based pigment particle grinding equipment provided by the invention moves up and down in the grinding barrel through the bearing piece, transfers the qualified pigment to be ground into the temporary storage chamber from the grinding chamber in the movement process, and transfers the pigment to the grinding chamber from the temporary storage chamber to be ground, so that the quantity of the qualified pigment in the temporary storage chamber is gradually increased in the transfer process, the quantity of the unqualified pigment in the grinding chamber is gradually reduced until all pigments are sufficiently ground, the grinding efficiency of the pigment is improved through intermittent feeding, and the situation that a large amount of pigment is required to be ground into the grinding container at one time, which results in the consumption of a large amount of time for sufficient grinding, is avoided.
