Description

Technical Field

[0001] This utility model relates to the field of chemical fiber spinning equipment technology, specifically to an integrated masterbatch feeding mechanism for producing stain-resistant BCF yarn. Background Technology

[0002] In the production process of stain-resistant BCF yarn, the stain-resistant masterbatch needs to be uniformly mixed with nylon 6 chips before being fed into the screw extruder. In existing technologies, the storage, mixing, and feeding of raw materials are mostly completed by independent equipment, which presents the following problems: First, when the mixed material is fed to the spinning assembly, it is prone to blockage at the outlet, leading to production interruptions and affecting efficiency and continuity; second, the separate arrangement of multiple devices results in a loose structure for the entire feeding mechanism, occupying a large area, and the material may be unevenly mixed or have residues during transfer; furthermore, the traditional single mixing method cannot ensure sufficient and uniform mixing of the masterbatch and the base raw materials, which may affect the consistency of the stain-resistant performance of the final yarn. Utility Model Content

[0003] The purpose of this invention is to provide an integrated masterbatch feeding mechanism for producing stain-resistant BCF yarn, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an integrated masterbatch feeding mechanism for producing stain-resistant BCF yarn, comprising:

[0005] A mixing chamber, wherein a discharge port is provided at the bottom end of the mixing chamber;

[0006] At least two feeding hoppers are provided for storing masterbatch raw materials and base raw materials, and the discharge end of the feeding hopper is connected to the interior of the mixing chamber;

[0007] The stirring module is used to stir and mix the raw materials put into the mixing chamber;

[0008] A booster, installed at the bottom of the discharge port, is used to promote material flow and prevent blockage.

[0009] Furthermore, the booster is a tubular structure adapted to the discharge port, and the center of the booster is provided with a discharge hole that gradually narrows from top to bottom. An annular cavity is provided on the outer side of the discharge hole along its circumference, and the bottom end of the annular cavity is connected to the discharge hole. An air inlet is provided on the outer wall of the booster and is connected to the annular cavity.

[0010] Furthermore, the feeding hopper is vertically positioned above the mixing chamber, and the bottom end of the feeding hopper is connected to the interior of the mixing chamber. A valve is provided at the discharge end of the feeding hopper to control the material delivery.

[0011] Furthermore, the stirring module includes a stirring rod and a rotation drive module. The stirring rod is rotatably mounted inside the mixing chamber, and the rotation drive module is used to drive the stirring rod to rotate.

[0012] Furthermore, a top cover is detachably installed at the top of the mixing chamber.

[0013] Furthermore, it also includes a support frame for supporting and securing the mixing chamber and the feeding hopper.

[0014] Furthermore, the support includes:

[0015] The first fixing plate is connected to the feeding hopper;

[0016] Several supporting legs are fixed to the bottom edge of the first fixing plate;

[0017] The second fixing plate is fixed to the inside of the plurality of supporting legs and is used to support the mixing chamber.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] (1) By using the booster set at the bottom of the discharge port, its special tapered discharge hole and annular cavity structure can effectively prevent the material from sticking and blocking at the outlet, ensuring the smooth flow of material and the continuity of the production process.

[0020] (2) Integrating at least two feeding hoppers, mixing chambers and stirring modules into one unit and supporting and fixing them in a unified manner with a bracket, the structure is compact, reducing the equipment floor space, avoiding the transfer of materials between multiple independent devices, and reducing the risk of residue and pollution;

[0021] (3) An integrated stirring module is used to force the raw materials in the mixing chamber to be stirred. Combined with the vertically set feeding hopper, the masterbatch and the basic raw materials can be mixed quickly and thoroughly, which effectively ensures the uniformity of the distribution of the anti-fouling components, thereby improving the stability and consistency of the final BCF yarn product quality.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please see Figure 1-3 An embodiment of this utility model provides an integrated masterbatch feeding mechanism for producing stain-resistant BCF yarn, comprising: a mixing chamber 1, a feeding hopper 2, a stirring module 3, a booster 4, a top cover 5, and a support 6.

[0028] The mixing chamber 1 is specifically a funnel-shaped chamber with an open top, and a flange ring is fixed at the edge of the top. The top cover 5 is detachably installed on the top of the mixing chamber 1 through the flange ring. The top cover 5 is provided with two feed ports, and the bottom of the mixing chamber 1 is provided with a discharge port 101.

[0029] In this embodiment, there are two feeding hoppers 2, which are used to store antifouling masterbatch and nylon 6 chips respectively. In actual application, the number can be adjusted as needed. The feeding hopper 2 is vertically set above the mixing chamber 1. Its top is open and can be sealed with a cover. The bottom is connected to the feed port on the top cover 5. The discharge end is equipped with a valve to control the material feeding.

[0030] The stirring module 3 includes a stirring rod 301 and a rotary drive module 302. The stirring rod 301 is rotatably installed inside the mixing chamber 1. The rotary drive module 302 is preferably a motor installed on the top cover 5. Its output shaft is directly connected to the stirring rod 301 or connected through a transmission mechanism to drive the stirring rod 301 to rotate, thereby achieving stirring and mixing of the input raw materials.

[0031] The booster 4 is installed at the bottom of the discharge port 101 to promote material flow and prevent blockage. Specifically, it is a tubular structure adapted to the discharge port 101 and can be fixed to it via a flange ring. The booster 4 has a discharge hole 401 at its center, tapering downwards, with its top dimension matching that of the discharge port 101. An annular cavity 402 is arranged circumferentially around the outer side of the discharge hole 401, and the bottom end of the annular cavity 402 communicates with the discharge hole 401. An air inlet 403, communicating with the annular cavity 402, is located on the outer wall of the booster 4. Its working principle is as follows: when compressed air enters the annular cavity 402 through the air inlet 403, it flows along a specific path to the central area of ​​the discharge hole 401. Based on the Venturi effect, a local negative pressure is formed here, generating a downward auxiliary traction force on the falling material, thereby effectively preventing blockage. To further control the material and isolate the hot air from downstream equipment, a valve can be added to the bottom of the booster 4.

[0032] The bracket 6 supports the entire mechanism and includes a first fixed plate 601, several support legs 602, and a second fixed plate 603. The first fixed plate 601 is a horizontal plate structure and is fixedly connected to the upper outer wall of each feeding hopper 2 through pre-set mounting holes. Several support legs 602 are vertically fixed at the bottom edge of the first fixed plate 601 to ensure that the first fixed plate 601 is horizontally positioned. The second fixed plate 603 is fixed to the inner middle or lower part of the several support legs 602, and has a through hole in its center for supporting and fixing the mixing chamber 1. Specifically, the flange ring of the mixing chamber 1 is supported on the second fixed plate 603, and the top cover 5, the flange ring of the mixing chamber 1, and the second fixed plate 603 are fastened together by bolts.

[0033] Working principle: Different raw materials are stored separately in the feeding hopper 2 and fed into the mixing chamber 1 according to the set ratio. They are then fully mixed by the stirring module 3. During discharge, compressed gas enters the annular cavity 402 through the air inlet 403. The gas speed increases as it flows through the discharge hole 401, forming a local negative pressure. This creates a downward "suction" on the falling mixture, effectively preventing blockage.
