Description

Technical Field

[0001] This utility model relates to a feeding mechanism, specifically a feeding mechanism for a color masterbatch adding device, and belongs to the field of feeding device technology. Background Technology

[0002] Color masterbatch is a plastic colorant made by dispersing a high proportion of pigments or additives with thermoplastic resin. The resin used has good wetting and dispersing properties for the colorant and good compatibility with the material being colored. During the addition process, color masterbatch is generally added directly into the processing equipment, which can easily lead to clogging problems. Furthermore, a single injection into the processing equipment can negatively impact the coloring effect.

[0003] A Chinese utility model patent (publication number: CN221968638U) discloses a feeding mechanism for a color masterbatch adding device. In the process of the drive belt being driven by the drive wheel, the drive belt drives the rotating wheel to rotate, and the rotating wheel drives the connecting shaft to rotate. When the connecting shaft starts to rotate, it drives multiple sets of deflectors to deflect the color masterbatch in the feed hopper, so that color masterbatch of appropriate size can be leaked out through the partition, thus isolating larger impurities in the color masterbatch.

[0004] By installing a baffle in the feed hopper, large particles of masterbatch can be effectively separated, ensuring the consistency of masterbatch addition. However, the baffle adopts a fixed design, which to some extent affects the passage of masterbatch. When the masterbatch flow rate is large or the particle distribution is uneven, the masterbatch is prone to accumulate on the baffle, thus affecting the masterbatch addition process. Therefore, a feeding mechanism for a masterbatch adding device is proposed. Utility Model Content

[0005] In view of this, the present invention provides a feeding mechanism for a color masterbatch adding device to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0006] The technical solution of this utility model embodiment is implemented as follows: a feeding mechanism of a color masterbatch adding device includes a screw conveyor, and an isolation component is provided above the screw conveyor;

[0007] The isolation assembly includes an isolation bucket, an isolation net, bearings, a support ring, a connecting rod, a drive motor, and a drive disc;

[0008] The isolation net is a cone-shaped structure with its opening facing upwards and is located inside the isolation hopper. A support frame is fixedly connected to the lower surface of the isolation net. The support frame is rotatably connected to the upper surface of a support ring via bearings. The support ring is fixedly connected to the inner wall of the isolation hopper. The drive disc is coaxially mounted on the output shaft of the drive motor via a coupling. One end of the connecting rod is rotatably connected to one side of the upper surface of the drive disc, and the other end of the connecting rod is rotatably connected to the upper surface of the isolation net. The drive motor is mounted on the outer wall of the isolation hopper.

[0009] More preferably, the outer wall of the isolation bucket has a clearance opening, and the connecting rod is located inside the clearance opening.

[0010] In a further preferred embodiment, an observation port is provided on one side of the upper surface of the isolation hopper.

[0011] More preferably, the top of the isolation hopper is fixedly connected to a feeding hopper that communicates with it, and the inside of the feeding hopper is rotatably connected to a rotating shaft.

[0012] More preferably, the outer side wall of the rotating shaft is symmetrically and fixedly connected with a feeding flap.

[0013] More preferably, a feeding motor is installed on one side of the feeding hopper, and the output shaft of the feeding motor is fixedly connected to one end of the rotating shaft through a coupling.

[0014] More preferably, a feeding hopper is installed on the upper surface of the discharge hopper, and the feeding hopper is funnel-shaped.

[0015] More preferably, the bottom of the isolation hopper is fixedly connected to a discharge pipe that communicates with it. The discharge pipe is installed at the feed inlet of the screw conveyor, and the isolation hopper is connected to the screw conveyor through the discharge pipe.

[0016] The present invention has the following advantages due to the adoption of the above technical solution:

[0017] This invention uses a drive motor to rotate a drive disc, which in turn drives a mesh screen to reciprocate through a connecting rod. Color masterbatch meeting the particle size requirements falls through the mesh of the mesh into a screw conveyor, which then transports the masterbatch to the processing equipment. Compared to existing technologies, this invention uses a crank-connecting rod mechanism composed of a drive motor, drive disc, and connecting rod to drive the mesh screen in a reciprocating motion. This allows the masterbatch to pass smoothly through the mesh, while also better collecting large particles and impurities in the middle of the mesh, further improving the filtration effect, reducing mesh clogging, and ensuring the stability of the masterbatch addition process.

Detailed Implementation

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1-6As shown, this utility model embodiment provides a feeding mechanism for a color masterbatch adding device, including a screw conveyor 31, and an isolation component 101 is provided above the screw conveyor 31;

[0030] The isolation assembly 101 includes an isolation bucket 11, an isolation net 12, a bearing 14, a support ring 15, a connecting rod 17, a drive motor 18, and a drive disc 19;

[0031] The isolation net 12 is a cone-shaped opening facing upwards and is located inside the isolation hopper 11. The mesh size of the isolation net 12 should be designed according to the particle size distribution of the masterbatch, and is usually slightly larger than the average outer diameter of the target masterbatch to ensure that the masterbatch can pass through smoothly. At the same time, it can also intercept large particles of masterbatch and impurities. After the impurities are intercepted, they are collected in the middle, which can reduce the risk of clogging of the mesh of the isolation net 12.

[0032] A support frame 13 is fixedly connected to the lower surface of the isolation net 12. The support frame 13 is rotatably connected to the upper surface of the support ring 15 through the bearing 14. The support ring 15 is fixedly connected to the inner wall of the isolation bucket 11, so that the isolation net 12 can rotate along the axis on the support ring 15.

[0033] The drive disk 19 is coaxially mounted on the output shaft of the drive motor 18 via a coupling. One end of the connecting rod 17 is rotatably connected to one side of the upper surface of the drive disk 19, and the other end of the connecting rod 17 is rotatably connected to the upper surface of the isolation net 12. The drive motor 18 is mounted on the outer wall of the isolation hopper 11. The drive motor 18, the drive disk 19, and the connecting rod 17 can form a crank-connecting rod mechanism, which drives the isolation net 12 to reciprocate, so as to ensure the passing efficiency of the masterbatch.

[0034] When the drive motor 18 rotates, it drives the drive disk 19 to rotate. The drive disk 19 drives the isolation screen 12 to reciprocate through the connecting rod 17. This oscillation helps the masterbatch pass through the isolation screen 12 more smoothly, and at the same time, it can better collect large masterbatch particles and impurities in the middle of the isolation screen 12, further improving the filtration effect and reducing the occurrence of mesh blockage.

[0035] In one embodiment, the outer wall of the isolation hopper 11 is provided with a clearance opening 16, and the connecting rod 17 is located inside the clearance opening 16. The clearance opening 16 can ensure the normal operation of the connecting rod 17. A protective cover (not shown in the figure) is provided outside the drive motor 18 and the drive disk 19 to prevent the staff from accidentally touching the rotating drive disk 19.

[0036] In one embodiment, an observation port 24 is provided on one side of the upper surface of the isolation hopper 11. The working status of the isolation net 12 can be observed in real time through the observation port 24. At the same time, large particles of masterbatch and impurities can be cleaned through the observation port 24.

[0037] In one embodiment, the top of the isolation hopper 11 is fixedly connected to a feeding hopper 23 that communicates with it. The inside of the feeding hopper 23 is rotatably connected to a rotating shaft 20. The outer side wall of the rotating shaft 20 is symmetrically fixedly connected to a feeding flap 21. A feeding motor 22 is installed on one side of the feeding hopper 23. The output shaft of the feeding motor 22 is fixedly connected to one end of the rotating shaft 20 through a coupling.

[0038] When the feeding motor 22 starts, it drives the rotating shaft 20 to rotate, and the rotating shaft 20 drives the feeding flap 21 to rotate accordingly. By controlling the rotation speed of the rotating shaft 20, the flow rate of masterbatch from the feeding hopper 23 into the isolation hopper 11 can be controlled.

[0039] When a larger flow rate is required, the rotational speed of the shaft 20 increases, and the throughput of the masterbatch increases;

[0040] When a smaller flow rate is required, the rotational speed of the shaft 20 is reduced, and the throughput of the masterbatch is reduced.

[0041] This allows for precise control of the masterbatch feeding speed based on actual production needs, ensuring the stability of subsequent processing and product quality.

[0042] In one embodiment, a feed hopper 32 is installed on the upper surface of the feed hopper 23. The feed hopper 32 is funnel-shaped, and the masterbatch is conveniently added into the feed hopper 23 through the feed hopper 32.

[0043] In one embodiment, the bottom of the isolation hopper 11 is fixedly connected to a discharge pipe 33 that communicates with it. The discharge pipe 33 is installed at the feed inlet of the screw conveyor 31. The isolation hopper 11 is connected to the screw conveyor 31 through the discharge pipe 33. The screw conveyor 31 is used to transport the masterbatch to the inside of the processing equipment.

[0044] In this utility model, both the feeding motor 22 and the drive motor 18 are variable frequency motors. The feeding motor 22, the drive motor 18 and the screw conveyor 31 are all existing technologies, so their internal structure, working principle and connection and control methods will not be described in detail.

[0045] When this utility model is in operation: color masterbatch is added into the feeding hopper 23, the feeding motor 22 drives the rotating shaft 20 to rotate, the rotating shaft 20 drives the feeding flap 21 to rotate accordingly, at this time the color masterbatch falls into the isolation hopper 11 and lands on the isolation net 12, the drive motor 18 drives the drive disc 19 to rotate, the drive disc 19 drives the isolation net 12 to perform reciprocating swing motion through the connecting rod 17, the color masterbatch that meets the particle size requirements falls into the screw conveyor 31 through the mesh of the isolation net 12, and then the screw conveyor 31 transports the color masterbatch into the interior of the processing equipment;

[0046] Compared with the prior art, this utility model can form a crank-connecting rod mechanism by using a drive motor 18, a drive disk 19 and a connecting rod 17 to drive the isolation net 12 to perform reciprocating swing motion, so that the masterbatch can pass through the isolation net 12 smoothly. At the same time, it can better collect large particles of masterbatch and impurities in the middle of the isolation net 12, further improving the filtration effect, reducing the occurrence of mesh blockage, and ensuring the stability of the masterbatch addition process.

[0047] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
