Description

Technical Field

[0001] This invention relates to the field of industrial yarn manufacturing technology, and in particular to a production equipment and method for producing black nylon 6 industrial yarn. Background Technology

[0002] Currently, the natural color of commonly used nylon 6 industrial yarn is white. To turn it black, the original white nylon 6 industrial yarn needs to be dyed with black dye to obtain black nylon 6 industrial yarn. However, this dyeing method is not only troublesome but also has problems such as poor dye penetration, uneven color, poor color fastness, and the dyed black color is also prone to fading.

[0003] Therefore, in order to obtain better black nylon 6 industrial yarn and avoid problems such as poor color fastness, the raw material, namely nylon 6 white chips, can be colored before producing nylon 6 industrial yarn.

[0004] One method involves mixing a certain proportion of black masterbatch into white nylon 6 chips to obtain a black nylon 6 filament with consistent color throughout, uniform color, and no color fading in the final product. However, this process presents challenges in terms of accurate proportioning and thorough mixing. Errors in the proportioning can lead to unstable color in the final product, while uneven mixing of the two raw materials can easily result in uneven color. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a production equipment and method for black nylon 6 industrial yarn, so as to solve the technical problem that it is difficult to control the accuracy of different raw material ratios in the prior art.

[0006] To achieve the above objectives, the present invention provides a production equipment for black nylon 6 industrial yarn, comprising a main material conveying pipe and an auxiliary material conveying pipe, used for conveying white chips and black masterbatch respectively. The production equipment further includes: The batching hopper is located behind the mixing mechanism. The batching hopper is divided into a main material storage chamber and an auxiliary material storage chamber by a main material and auxiliary material partition. The main material storage chamber and the auxiliary material storage chamber are respectively connected to the main material conveying pipe and the auxiliary material conveying pipe. A separating material dispensing assembly is provided on the outer wall of the material dispensing hopper. The separating material dispensing assembly is provided in two sets, which are used to drive the main material telescopic plate to move in the main material temporary storage cavity and the auxiliary material telescopic plate to move in the auxiliary material temporary storage cavity, respectively. There is one main material telescopic plate and five auxiliary material telescopic plates. The capacity of the main material temporary storage cavity below the main material telescopic plate is 20 times the capacity of the auxiliary material temporary storage cavity below the top auxiliary material telescopic plate. The bottom of the ingredient hopper is provided with a feed inlet that communicates with the interior of the mixing mechanism, and the feed inlet is provided with a sealing plate that can be opened or closed.

[0007] Furthermore, the capacity of the auxiliary material storage cavity below the top auxiliary material telescopic plate is divided into five equal parts by the other four auxiliary material telescopic plates.

[0008] Furthermore, the separating batching assembly includes a pressure chamber and a connector fixedly connected between the batching chamber and the pressure chamber. The main material telescopic plate and the auxiliary material telescopic plate are slidably connected inside their respective connectors, and the outer end of the inner cavity of the connector communicates with the inner cavity of the pressure chamber. The inner cavity of the pressure chamber is connected to an external air pump and an air extractor through an air supply pipe.

[0009] Furthermore, a stop is provided at the connection point between the outer end of the inner cavity of the connector and the inner cavity of the air pressure chamber to limit the displacement of the main material telescopic plate and the auxiliary material telescopic plate.

[0010] Furthermore, the bottom of the connector is also provided with an electromagnetic latch for locking the main material telescopic plate and the auxiliary material telescopic plate.

[0011] Furthermore, the electromagnetic lock includes a housing and an electromagnetic coil disposed within the housing. A locking rod passes through the electromagnetic coil, and the upper end of the locking rod passes through a connector and extends into its interior. The bottom of the main material telescopic plate and the auxiliary material telescopic plate are provided with locking holes that cooperate with the locking rod. A metal disc is fixedly connected to the lower end of the locking rod, and an intermediate plate is also fixedly connected to the locking rod above the electromagnetic coil. A spring is connected between the intermediate plate and the electromagnetic coil, and the spring is sleeved on the locking rod.

[0012] Furthermore, the mixing mechanism and the ingredient bin are both fixedly connected to the support, and the support is also equipped with a cylinder. The sealing plate is connected to the output shaft of the cylinder, and a vibration motor is fixedly connected to the bottom of the ingredient bin.

[0013] Furthermore, the mixing mechanism includes a mixing chamber and a mixing motor. The mixing motor is fixedly connected inside the mixing chamber, and the mixing chamber is rotatably connected to a stirring blade. The stirring blade is connected to the output shaft of the mixing motor via a rotating shaft, and the stirring blade is provided with a through groove.

[0014] Furthermore, the bottom of the mixing chamber is provided with a discharge port, and a discharge valve is also provided at the discharge port.

[0015] The production method using the above-mentioned equipment is characterized by comprising the following steps: 1.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0030] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0031] The first aspect of the invention, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, by mixing a certain proportion of black masterbatch into the nylon 6 white chip raw material, a black nylon 6 filament with consistent color throughout and without fading can be obtained in the final product. However, this process also presents challenges in terms of accurate proportioning and thorough mixing. Errors in the proportioning will result in unstable color in the final product, while uneven mixing of the two raw materials will easily lead to uneven color. Therefore, this invention provides a batching bin 103 behind the mixing mechanism, in which the white chips and black masterbatch are conveyed through the main material conveying pipe 101 and the auxiliary material conveying pipe 102, respectively.

[0032] The mixing hopper 103 is fixedly connected to a main and auxiliary material partition 116, which divides the inner cavity of the mixing hopper 103 into a main material temporary storage cavity 113 and an auxiliary material temporary storage cavity 117. The main material temporary storage cavity 113 and the auxiliary material temporary storage cavity 117 are respectively connected to the main material conveying pipe 101 and the auxiliary material conveying pipe 102.

[0033] To ensure accurate proportioning in the mixing bin 103, a separating mixing assembly 108 is installed on the outer wall of the mixing bin 103. Two sets of separating mixing assemblies 108 are provided, one for driving the main material telescopic plate 115 to move within the main material temporary storage cavity 113, and the other for driving the auxiliary material telescopic plate 118 to move within the auxiliary material temporary storage cavity 117. There is one main material telescopic plate 115 and five auxiliary material telescopic plates 118. The capacity of the main material temporary storage cavity 113 below the main material telescopic plate 115 is 20 times the capacity of the auxiliary material temporary storage cavity 117 below the top auxiliary material telescopic plate 118.

[0034] Preferably, the mixing mechanism and the batching bin 103 are both fixedly connected to the support 105. The support 105 is also equipped with a cylinder 112. The sealing plate 111 is connected to the output shaft of the cylinder 112. The bottom of the batching bin 103 is fixedly connected to a vibration motor 110.

[0035] After the main material conveying pipe 101 and the auxiliary material conveying pipe 102 convey nylon 6 white chips and black masterbatch into the main material storage chamber 113 and the auxiliary material storage chamber 117 in the batching bin 103 respectively, the vibration motor 110 is started to ensure that the raw materials in the main material storage chamber 113 and the auxiliary material storage chamber 117 are properly stored.

[0036] Then the separating batching assembly 108 is activated, so that the main material telescopic plate 115 and the auxiliary material telescopic plate 118 extend out of the inner cavity of the separating batching bin 103. At this time, the nylon 6 white chips in the main material temporary storage cavity 113 below the main material telescopic plate 115 are the raw materials for this round of mixing.

[0037] Preferably, the capacity of the auxiliary material storage cavity 117 below the top auxiliary material telescopic plate 118 is divided into five equal parts by the other four auxiliary material telescopic plates 118. Therefore, each part of black masterbatch is 1% of the nylon 6 white chips in the main material storage cavity 113 below the main material telescopic plate 115.

[0038] The proportion of black masterbatch in the auxiliary material storage chamber 117 can be selected as needed. By retracting the corresponding number of auxiliary material telescopic plates 118, the specific proportion can be selected. There are five proportions available: 1%, 2%, 3%, 4%, and 5%, which can meet more needs and ensure accurate control of the black masterbatch proportion.

[0039] Finally, after the materials are mixed in the batching bin 103, the sealing plate 111 is driven down by the cylinder 112 to open the feed port 119 and allow all the materials to flow into the mixing mechanism.

[0040] The second aspect of the invention, as Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the separating batching assembly 108 includes a pressure chamber 120 and a connector 121 fixedly connected between the batching chamber 103 and the pressure chamber 120. The main material telescopic plate 115 and the auxiliary material telescopic plate 118 are slidably connected inside their respective connectors 121, and the outer end of the inner cavity of the connector 121 communicates with the inner cavity of the pressure chamber 120. The inner cavity of the pressure chamber 120 is connected to an external air pump and a vacuum pump through an air supply pipe 109.

[0041] By blowing or sucking air into the air pressure chamber 120 using an external air pump or vacuum pump, the air pressure inside the air pressure chamber 120 can be adjusted. When the air pressure is greater than the external air pressure, it can push the main material telescopic plate 115 and the auxiliary material telescopic plate 118 to extend. When the air pressure is less than the external air pressure and becomes negative pressure, it can drive the main material telescopic plate 115 and the auxiliary material telescopic plate 118 to retract. The control is simple and convenient.

[0042] Preferably, a stop 122 is provided at the outer end of the inner cavity of the connector 121 where it communicates with the inner cavity of the air pressure chamber 120, to limit the displacement of the main material telescopic plate 115 and the auxiliary material telescopic plate 118.

[0043] In addition, in order to precisely control the movement of each auxiliary material telescopic plate 118 and the main material telescopic plate 115, an electromagnetic lock 123 is also provided at the bottom of the connector 121 to lock the main material telescopic plate 115 and the auxiliary material telescopic plate 118.

[0044] The electromagnetic latch 123 includes a housing and an electromagnetic coil 124 disposed inside the housing. A locking rod 125 passes through the electromagnetic coil 124. The upper end of the locking rod 125 passes through the connector 121 and extends into its interior. The bottom of the main material telescopic plate 115 and the auxiliary material telescopic plate 118 are provided with locking holes that cooperate with the locking rod 125. A metal disc 126 is fixedly connected to the lower end of the locking rod 125. An intermediate plate 127 is also fixedly connected to the locking rod 125 above the electromagnetic coil 124. A spring 128 is connected between the intermediate plate 127 and the electromagnetic coil 124 and is sleeved on the locking rod 125.

[0045] In addition, the mixing mechanism includes a mixing chamber 104 and a mixing motor 107. The mixing motor 107 is fixedly connected inside the mixing chamber 104. The mixing chamber 104 is rotatably connected to a stirring blade 129. The stirring blade 129 is connected to the output shaft of the mixing motor 107 through a rotating shaft, and the stirring blade 129 is provided with a through groove 130.

[0046] The bottom of the mixing chamber 104 is provided with a discharge port 106, which is also equipped with a discharge valve 131, and the discharge port 106 is connected to the screw extruder. The black masterbatch and nylon 6 white chips are stirred and mixed in the mixing mechanism and then extruded into the screw extruder for spinning and winding, finally obtaining black nylon 6 industrial yarn.

[0047] In summary, this invention, by adding black masterbatch to nylon 6 white chip raw materials in advance, can obtain black nylon 6 industrial yarn. The proportion of black masterbatch can be adjusted between 1-5% according to actual needs, resulting in black nylon 6 industrial yarn with consistent and uniform color throughout, and without fading. A mixing hopper 103 is provided, into which materials are first injected, followed by precise proportioning. Five proportions are available: 1%, 2%, 3%, 4%, and 5%, which can meet various needs and ensure accurate control of the black masterbatch proportion.
