Description

Technical Field

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

[0002] Masterbatch refers to a plastic colorant made of a high proportion of pigments or additives and thermoplastic resins that are well dispersed. The selected resin has a good wetting and dispersing effect on the colorant and has good compatibility with the colored material. When producing masterbatches, the raw materials must first be output as columnar masterbatches through an extruder.

[0003] For example, a masterbatch extruder with publication number CN206589319U includes a frame, a barrel is arranged on the frame, and an extrusion screw is arranged in the barrel. The masterbatch extruder of the utility model has high heating efficiency, and the masterbatch is not easy to deform;

[0004] The masterbatch extruder is provided with an extrusion screw in a barrel, and the masterbatch raw materials are extruded through the extrusion screw. However, since there is no cleaning structure in the barrel, when the masterbatch raw materials in the barrel are heated, a part of the masterbatch raw materials in a molten state will adhere to the inner wall of the barrel, which will not only cause a waste of raw materials, but also be unfavorable for subsequent cleaning work. At the same time, the water pipe is directly connected to the cold water hole on the die body, but no circulating cooling structure is provided on the die, so the cooling effect of the masterbatch raw materials passing through the die body is not good, thereby reducing the quality of the finished product after the masterbatch is extruded. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a masterbatch extruder, which solves the problem that the existing masterbatch extruder has no cleaning structure in the barrel. Therefore, when the masterbatch raw materials in the barrel are heated, a part of the masterbatch raw materials in a molten state will adhere to the inner wall of the barrel, which will not only cause waste of raw materials, but also be detrimental to subsequent cleaning work. At the same time, the above-mentioned method directly connects the water pipe to the cold water hole on the die body, but does not have a circulating cooling structure on the die, so the cooling effect on the masterbatch raw materials passing through the die body is not good.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a masterbatch extruder, including an extruder body and legs, a pair of legs are fixedly connected to the bottom of the extruder body, a feed hopper is fixedly connected to the upper left side of the extruder body, an extrusion screw is rotatably connected to the inside of the extruder body through a pair of bearings, a connecting plate is threadedly connected to the right side of the extruder body through a plurality of bolts, and a die body is fixedly connected to the inside of the connecting plate, a cleaning mechanism is installed on the outer wall of the extrusion screw, and a cooling mechanism is installed on the upper right side of the extruder body.

[0007] Preferably, the cleaning mechanism includes a connecting rod fixedly connected to the outer walls at both ends of the extrusion screw, and the upper and lower outer walls of the connecting rod are fixedly connected with scrapers that fit the inner wall of the cylindrical cavity of the extruder body. The left side of the extruder body is fixedly connected to a base, and the inside of the base is fixedly connected to a motor connected to the extrusion screw.

[0008] Preferably, heating tube groups are fixedly connected to the upper and lower parts of the extruder body.

[0009] Preferably, the cooling mechanism includes a support fixedly connected to the upper right side of the extruder body, a water tank is fixedly connected to the upper part of the support, a horizontal plate is fixedly connected to the middle of the right side of the water tank, and a water pump is fixedly connected to the inside of the horizontal plate, the water outlet and water inlet of the water pump are respectively fixedly connected to the first pipe and the second pipe, and the other ends of the first pipe and the second pipe are connected to the inside of the water tank, and the middle outer wall of the first pipe is wound and connected to the outer wall of the die body.

[0010] Preferably, a refrigeration fin and a water inlet pipe are fixedly connected to the middle of the left side and the upper right side of the water tank respectively.

[0011] Preferably, an observation window is fixedly connected to the left side of the front end surface of the water tank.

[0012] Beneficial Effects

[0013] The utility model provides a masterbatch extruder, which has the following beneficial effects:

[0014] The masterbatch raw material can be poured into the extruder body through the feed hopper, and then the heating tube group and the motor are started. The masterbatch raw material inside the extruder body can be heated by the heating tube group to form a molten state, and then the output shaft of the motor drives the extrusion screw to rotate, so that the masterbatch raw material can be transported by the extrusion screw, and the masterbatch raw material is extruded through the die body. At the same time, when the extrusion screw rotates, it drives the connecting rod to rotate, so that the connecting rod drives the scraper to rotate, and because the interior of the extruder body is a cylindrical cavity, the material adhering to the inner wall of the extruder body can be scraped off by the scraper, thereby not only avoiding the waste of the masterbatch raw material, but also facilitating the subsequent cleaning work;

[0015] When the masterbatch raw material is extruded, the refrigeration sheet and the water pump can be started. The water in the water tank can be cooled by the refrigeration sheet. The water pump then sucks the cooling water out of the water tank through the second pipe and discharges the cooling water into the first pipe. The cooling water will flow back to the water tank through the first pipe to form a cycle. At the same time, when the cooling water flows through the outer wall of the die body, it will take away the heat of the masterbatch raw material in the die body and cool it down. In this way, the masterbatch raw material can be smoothly extruded, thereby improving the quality of the finished product after the masterbatch is extruded. BRIEF DESCRIPTION OF THE DRAWINGS
