Description

Technical Field

[0001] This utility model relates to the field of spinning technology, and in particular to a masterbatch addition device for producing uniformly sized masking yarns. Background Technology

[0002] Sunscreen yarn is a type of nylon yarn that effectively blocks solar heat and ultraviolet rays. It is commonly used in the production of sun-protective clothing and has become increasingly popular with consumers in recent years. The production process of sunscreen yarn requires the addition of UV-resistant additives and the use of irregularly shaped cross-sections to achieve the best sun-protection effect.

[0003] In the preparation of masking yarn, it is necessary to blend the auxiliary masterbatch and nylon 6 chips before extruding and spinning them using a screw extruder. Existing masterbatch addition devices, such as... Figure 1 As shown, from top to bottom, it includes a feeding area 101, a weighing area 102, a mixing area 103, and a hopper 1'. After the material is uniformly mixed in the mixing section of the masterbatch mill, it is placed into the hopper. Because the hopper has a funnel-shaped discharge port, uneven mixing can occur. The main reasons for this are as follows: 1. The material flow rate in the middle of the hopper is faster than that around the hopper, while the weight of the masterbatch is greater than that of the nylon 6 chips. As is well known, heavier materials sink, which causes the flow rate of the masterbatch to be faster than that of the nylon 6 chips. This results in the uniformly mixed material entering the screw extruder in an uneven manner.

[0004] 2. During the feeding process, there is static electricity between plastic particles due to friction. The inner wall of the hopper is prone to adsorbing plastic particles, especially pure PA6 particles, due to static electricity. This will cause stratification between PA6 particles and additive particles, resulting in uneven feeding.

[0005] In addition, the mixing chamber in the mixing zone discharges material through the discharge port 1031 located at the rear while mixing. The discharge port 1031 connects to the middle and rear part of the top of the silo to form a discharge outlet. Because the material is discharged while mixing, it is thrown to the corners of the silo due to inertia, rather than in the center, which easily leads to corner accumulation. At the same time, the particles bounce off the side walls of the silo during the discharge process. Due to the density difference between pure PA6 particles and additive particles, the rebounded particles are distributed in different positions, which can easily cause uneven distribution.

[0006] Therefore, during the preparation of masking yarn, the addition of auxiliary masterbatch reduces the uniformity of the fiber, resulting in a decrease in the rate of high-quality products and production efficiency, such as a decrease in fiber evenness and a worsening of dyeing unevenness. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a masterbatch addition device for producing uniformly performing masking yarn.

[0008] This utility model is implemented as follows: A masterbatch adding device for producing uniformly sized masking yarn includes a hopper located below the feed port of a masterbatch machine, the feed port extending into the interior of the hopper, and the hopper being frustum-shaped.

[0009] Furthermore, the discharge port extends to one-third of the space inside the hopper.

[0012] Furthermore, a viewing window is provided on one side wall of the silo.

[0013] Furthermore, the silo is equipped with a level gauge.

[0014] The advantages of this utility model are: 1. This utility model extends the length of the discharge port of the mixing chamber, so that the mixed materials fall into the middle of the silo, avoiding the accumulation of materials in corners and the material separation caused by the rebound of the mixed materials when they are thrown against the silo wall.

[0015] 2. This utility model improves the uniformity of material feeding by changing the hopper structure from a funnel shape to a frustum shape, and at the same time changes the curved shape of the hopper structure to a straight shape to avoid the phenomenon of material accumulation at corners.

[0016] 3. This utility model, by designing a feeding port and a discharging port on the silo, facilitates the replacement of the raw materials in the silo at any time, greatly saving replacement time.

[0017] 4. This utility model features a viewing window on the hopper for easy observation of the raw material's condition inside; the nitrogen interface, connected to a nitrogen output device, supplies nitrogen to the hopper, providing nitrogen protection to the entire masterbatch machine and preventing raw material oxidation.

[0022] In the description of this utility model, it should be understood that the description indicating the orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Products whose specific structures are not specified in the examples are all conventional products that can be purchased commercially.

[0025] In a specific embodiment of the technical solution of this utility model: The technical solution of this utility model is as follows: Please see Figure 2 As shown, the present invention provides a masterbatch adding device for producing uniformly sized masking filaments, comprising a hopper 1 located below the discharge port of the masterbatch machine.

[0026] The masterbatch mill 100 is a commercially available masterbatch mill, which includes a feeding area 101, a weighing area 102, and a mixing area 103 from top to bottom. The hopper 1 is located below the masterbatch mill 100. The mixing area 103 includes a mixing chamber 104. The discharge port 105 of the mixing chamber 104 extends into the interior of the hopper 1, up to 1 / 3 of the space inside the hopper, so that the mixed material can fall into the middle of the hopper. This ensures that the discharge direction of the mixed material is not affected by the agitator, avoiding corner accumulation and material separation caused by the mixed material being thrown against the hopper wall and rebounding.

[0027] The silo 1 is frustum-shaped. The original silo structure was funnel-shaped, which led to increased stratification of the mixed material and accumulation of material in corners. By changing the silo structure from funnel-shaped to frustum-shaped, the mixing of materials relies on gravity to reduce the adsorption of pure PA6 particles on the side walls, thereby improving the uniformity of material feeding. At the same time, the curved shape of the silo structure is changed to a straight shape to avoid the accumulation of mixed materials in corners and reduce stratification.

[0028] The hopper 1 has a feeding port 2 and a discharging port 3 on the upper and lower parts of both sides, which facilitates the replacement of the raw materials in the hopper at any time and greatly saves replacement time.

[0029] The hopper 1 is equipped with a nitrogen port 4 to provide nitrogen protection for the entire masterbatch machine and prevent the raw materials from oxidizing.

[0030] A viewing window 5 is provided on one side wall of the silo 1 to facilitate observation of the state of the raw materials inside the silo.

[0031] A level gauge 6 can also be installed in the silo 1 to detect the height of the material in the silo 1.

[0032] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
