Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch grinding, in particular to a masterbatch grinding device. Background Art

[0002] At present, the full name of masterbatch is masterbatch, also called color seed, which is a new type of colorant for polymer materials, also called pigment preparation. Masterbatch is mainly used in plastics. Masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate obtained by uniformly attaching an extraordinary amount of pigment to the resin, which can be called pigment concentrate. Therefore, its coloring power is higher than the pigment itself. When processing, a small amount of masterbatch is mixed with uncolored resin to achieve the coloring resin or product with the designed pigment concentration.

[0003] Among them, when processing the masterbatch, the masterbatch needs to be ground so that the masterbatch can be better processed.

[0004] When grinding masterbatches on the market, the grinding equipment directly introduces the masterbatch into the grinding equipment for grinding. However, in this way, the masterbatch raw materials will contain large particles of masterbatch that stick together, which will greatly affect the grinding efficiency of the masterbatch. Therefore, we propose a masterbatch grinding device to solve the above problem. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4 A masterbatch grinding device comprises: a grinding chamber 1, a rotating shaft 11 is fixedly installed on the bottom side of the grinding chamber 1, three groups of grinding blocks 12 with equal spacing are fixedly installed on the rotating shaft 11, and a material guide cover 13 is fixedly installed on the top of the three groups of grinding blocks 12, and a high-efficiency grinding mechanism is fixedly installed inside the grinding chamber 1;

[0024] The high-efficiency grinding mechanism includes a dividing ring 2 fixedly installed at the top of the grinding bin 1, a plurality of groups of equally spaced first protrusions 21 fixedly installed on the inner wall of the dividing ring 2, a breaking ring 22 fixedly installed in the middle of the grinding bin 1, a plurality of groups of equally spaced second protrusions 23 fixedly installed on the inner wall of the breaking ring 22, and a grinding ring 24 fixedly installed at the bottom of the grinding bin 1. The dividing ring 2, the breaking ring 22, and the grinding ring 24 correspond to the three groups of grinding blocks 12 respectively. Each group of grinding blocks 12, the dividing ring 2, the breaking ring 22, and the grinding ring 24 are made of grinding stone. The rotating shaft 11 is driven to rotate by the driving motor 31, and the grinding ring 24 can be driven to rotate. The three groups of grinding wheels rotate synchronously inside the grinding bin 1, and the dividing ring 2, the breaking ring 22 and the grinding ring 24 in the high-efficiency grinding mechanism are used at the same time. The masterbatch introduced into the grinding bin 1 can be divided first, so that the block-shaped and adhered masterbatch can be divided and introduced into the breaking ring 22 with distinct particles. The second protrusion 23 inside the breaking tube rubs against the grinding block 12, so that the masterbatch with distinct particles can be broken, and the originally larger masterbatch can be ground into small particles and introduced into the grinding ring 24. Finally, the inner wall of the grinding ring 24 rubs against the outer wall of the grinding block 12, so that the masterbatch raw material can be efficiently ground into powder.

[0025] Furthermore, multiple groups of equidistantly distributed stirring rods 34 are fixedly installed at the bottom of the rotating shaft 11, and the other ends of the multiple groups of stirring rods 34 are fixedly installed with a material stripping plate 36, which improves the discharge efficiency. A discharge port 14 is opened on one side of the bottom of the grinding bin 1, and a valve is installed on the discharge port 14 to control the flow rate of the discharge port 14. When a large amount of masterbatch raw materials are ground by the three groups of grinding blocks 12, the rotating rotating shaft 11 will synchronously drive the stirring rod 34 to rotate, and the material stripping plate 36 is installed at the other end of the stirring rod 34, so that the masterbatch powder inside the grinding bin 1 can be continuously discharged from the discharge port 14, thereby improving the discharge efficiency.

[0026] Furthermore, a protective cover 3 is fixedly installed on the top of the grinding bin 1, and a notch is opened on one side of the protective cover 3, which corresponds to the conveyor belt 33. A motor 31 is fixedly installed on the top of the protective cover 3, and the output end of the motor 31 is connected to the transmission shaft, and the other end of the transmission shaft is fixedly installed on the top of the rotating shaft 11, which can drive the rotating shaft 11 to rotate. When the motor 31 on the top of the protective cover 3 is driven, the rotating shaft 11 can be driven to rotate to grind the masterbatch inside the grinding bin 1. At the same time, the protective cover 3 can prevent the masterbatch particles from splashing to the outside of the grinding bin 1, causing waste of masterbatch.

[0027] Furthermore, a support frame 32 is fixedly installed on the top of the side wall of the grinding bin 1, and a conveyor belt 33 is fixedly installed on the top of the support frame 32. One end of the conveyor belt 33 corresponds to the inside of the grinding bin 1, and the masterbatch can be transported. A large amount of masterbatch can be placed on the conveyor belt 33, and a large amount of masterbatch can be introduced into the grinding bin 1 in conjunction with the conveyor belt 33.

[0028] When in use, a large amount of masterbatch is first placed on the conveyor belt 33, and a large amount of masterbatch can be introduced into the grinding bin 1 with the conveyor belt 33. When the driving motor 31 drives the rotating shaft 11 to rotate, the three groups of grinding can be driven to rotate synchronously inside the grinding bin 1. At the same time, the dividing ring 2, the breaking ring 22 and the grinding ring 24 in the high-efficiency grinding mechanism can be used to divide the masterbatch introduced into the grinding bin 1 first, so that the block-shaped and adhered masterbatch can be divided, and the masterbatch with distinct particles can be introduced into the breaking ring 22. With the cooperation of the second protrusion 23 inside the breaking tube and the grinding block 12 rubbing against each other, the masterbatch with distinct particles can be broken, so that the originally larger volume masterbatch can be crushed. Large masterbatch is ground into small particles and introduced into the grinding ring 24. Finally, the inner wall of the grinding ring 24 and the outer wall of the grinding block 12 rub against each other, so that the masterbatch raw materials can be efficiently ground into powder. At the same time, multiple groups of equidistantly distributed stirring rods 34 are fixedly installed at the bottom of the rotating shaft 11, and the other ends of the multiple groups of stirring rods 34 are fixedly installed with a material stripping plate 36. When a large amount of masterbatch raw materials are ground by the three groups of grinding blocks 12, the rotating rotating shaft 11 will synchronously drive the stirring rod 34 to rotate. In combination with the material stripping plate 36 installed at the other end of the stirring rod 34, the masterbatch powder inside the grinding bin 1 can be continuously guided out and discharged from the discharge port 14, thereby improving the discharge efficiency.

[0029] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
