Description

Technical Field

[0001] This utility model relates to the field of color masterbatch technology, specifically a rapid cooling molding device for color masterbatch production. Background Technology

[0002] Color masterbatch, also known as colorant or pigment preparation, is a new type of colorant specifically designed for coloring polymer materials. It is mainly composed of three basic elements: pigment or dye, carrier, and additives. By uniformly loading an extraordinary amount of pigment into the resin, a pigment concentrate is formed, which has a higher coloring power than the pigment itself. The production of color masterbatch mainly includes steps such as raw material preparation, pigment and dispersion treatment, raw material mixing, and granulation. In the granulation stage, after the blended material is extruded through a special nozzle, it needs to be cooled in time to form the color masterbatch.

[0003] In the prior art, patent publication number CN 217196361 U proposes a rapid cooling device after drying masterbatch. Although it can achieve rapid cooling of masterbatch, the movement of masterbatch in the cooling device during the cooling process still requires the participation of the masterbatch's own weight. The masterbatch is prone to insufficient dispersion in the cooling molding device, which affects the cooling molding speed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a rapid cooling and molding device for color masterbatch production. This device accurately guides the movement trajectory of the color masterbatch within the cooling and molding device, which can make the color masterbatch more dispersed within the device, accelerate the discharge of heat from the color masterbatch, and speed up the cooling and molding process. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid cooling molding device for color masterbatch production, comprising a cooling cylinder, wherein a discharge pipe is provided at the discharge port on the outer arc surface of the cooling cylinder, and a guiding mechanism is also included;

[0006] The guiding mechanism includes a conveying pipe, a spiral conveying rod, and a guide plate.

A guide plate is rotatably connected to the outer arc surface of the conveying pipe. The guide plate follows a planar spiral trajectory with the conveying pipe as the center. A feed hopper is provided at the feed inlet on the outer arc surface of the conveying pipe.

[0007] Furthermore, the guiding mechanism also includes turntables, which are rotatably connected to the left and right ends of the inner arc surface of the cooling cylinder, and a guide plate is disposed between the two turntables.

[0008] Furthermore, the guiding mechanism also includes guiding holes, which are respectively disposed on the surface of the turntable. The guiding holes are evenly distributed in a planar spiral trajectory with the feed pipe as the center, guiding the airflow through the interior of the masterbatch along the axial direction.

[0009] Furthermore, the guiding mechanism also includes guiding through holes, which are respectively disposed inside the guiding rotating plate. The guiding through holes are evenly distributed in a planar spiral trajectory with the material conveying pipe as the center. The inner arc wall of the guiding through holes is provided with air blowing grooves.

[0010] Furthermore, it also includes filters, which are respectively disposed on the opposite inner surfaces of the two turntables to prevent color masterbatch from entering the guide hole.

[0011] Furthermore, a control switch group is provided on the front surface of the support of the cooling cylinder. The input end of the control switch group is electrically connected to an external power source to control the start and stop of the entire device.

[0012] Furthermore, a drive motor is provided on the left side of the cooling cylinder, and the output shaft of the drive motor is fixedly connected to the center of the left turntable.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By coordinating the feeding pipe, the spiral feeding rod, and the guide plate, the movement trajectory of the masterbatch within the cooling and molding device is accurately guided.

[0022] It also includes a guiding mechanism 4; the guiding mechanism 4 includes a conveying pipe 41, a spiral conveying rod 42, and a guiding plate 43. The conveying pipe 41 is installed in the mounting hole in the middle of the right side of the cooling cylinder 1. The spiral conveying rod 42 is rotatably connected inside the conveying pipe 41. The lower end of the outer arc surface of the conveying pipe 41 is provided with a discharge hole, which is located inside the cooling cylinder 1. The outer arc surface of the conveying pipe 41 is rotatably connected with the guiding plate 43. The guiding plate 43 follows a planar spiral trajectory with the conveying pipe 41 as the center. A feeding hopper 3 is provided at the inlet of the outer arc surface of the conveying pipe 41. The guiding mechanism 4 also includes a turntable 44, which is rotatably connected to the left and right ends of the inner arc surface of the cooling cylinder 1. The guiding plate 43 is located between the two turntables 44. The conveying pipe 41 passes through the middle of the right turntable 44. The left end of the spiral feed rod 42 is fixedly connected to the middle of the left turntable 44, and the right end of the spiral feed rod 42 is rotatably connected to the inner wall of the right side of the feed pipe 41. The turntable 44 drives the spiral feed rod 42 and the guide plate 43 to rotate. The guide mechanism 4 also includes guide holes 45, which are respectively set on the surface of the turntable 44. The guide holes 45 are evenly distributed in a planar spiral trajectory with the feed pipe 41 as the center. The guide mechanism 4 also includes guide through holes 46, which are respectively set inside the guide plate 43. The guide through holes 46 are evenly distributed in a planar spiral trajectory with the feed pipe 41 as the center. The inner arc wall of the guide through holes 46 is provided with air grooves. The guide through holes 46 are respectively connected to the air inlet holes on the surface of the right turntable 44.

[0023] The system also includes a filter screen 6, which is respectively set on the inner side of the two turntables 44 to prevent the masterbatch from entering the guide hole 45; a drive motor 5 is provided on the left side of the cooling cylinder 1, and the output shaft of the drive motor 5 is fixedly connected to the middle of the left turntable 44; an electric fan 7 is provided in the air hole on the right side of the cooling cylinder 1, and the four electric fans 7 are arranged in a ring around the feed pipe 41. The input ends of the drive motor 5 and the electric fans 7 are electrically connected to the output end of the control switch group 8.

[0024] The working principle of this utility model is as follows:

[0025] During the production of color masterbatch, the color masterbatch is poured into the inside of the conveying pipe 41 through the feed hopper 3;

[0026] The drive motor 5 is started by controlling the switch group 8. The output shaft of the drive motor 5 drives the turntable 44, the spiral conveyor rod 42 and the guide plate 43 to rotate. Through the cooperation between the spiral conveyor rod 42 and the inner arc surface of the conveying pipe 41, a leftward thrust is applied to the masterbatch in the conveying pipe 41, so that the masterbatch enters the interior of the cooling cylinder 1 and then falls down from the discharge hole on the outer arc surface of the conveying pipe 41. The masterbatch falls to the inner arc surface of the guide plate 43.

[0027] As the guide plate 43 drives the masterbatch to rotate, under the action of centrifugal force, the masterbatch gradually moves away from the conveying pipe 41 along the inner arc surface of the spiral plane of the guide plate 43, guiding the movement trajectory of the masterbatch inside the cooling cylinder 1, so that the masterbatch is more dispersed in the cooling cylinder 1.

[0028] Simultaneously, the electric fan 7 is activated to guide the airflow, allowing external air to enter the cooling cylinder 1 through the air vents on the right side. Then, a portion of the air enters the cooling cylinder 1 through the guide hole 45 on the right side along the axial direction and contacts the dispersed masterbatch to cool and shape it. Another portion of the air enters the guide hole 46 through the air inlet holes on the surface of the turntable 44 on the right side, and finally blows out from the air vents on the inner wall of the guide hole 46, so that the airflow contacts the masterbatch from different angles, making the cooling more uniform and improving the molding quality of the masterbatch.

[0029] The air that has absorbed heat is discharged through the guide hole 45 on the left side and the air hole on the left side of the cooling cylinder 1. After the cooled masterbatch is separated from the guide plate 43, it will be discharged from the discharge pipe 2 along the inner arc surface of the cooling cylinder 1.

[0030] It is worth noting that the drive motor 5 and electric fan 7 disclosed in the above embodiments can be freely configured according to the actual application scenario. The drive motor 5 can be a 5IK40RGU-CF model motor, and the electric fan 7 can be a 12020 model cooling fan. The control switch group 8 is provided with switch buttons that correspond one-to-one with the drive motor 5 and the electric fan 7 for controlling their switching operation.

[0031] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
