Description

Technical Field

[0001] The invention belongs to the technical field of bead-head yarn preparation, and in particular relates to a bead-head yarn and a preparation method and application thereof. Background Art

[0002] At present, the beaded hair combs are generally made by the method of dotting and dyeing. This process uses thixotropic, non-flowing epoxy resin as the bead material. The implanted hair combs are cured at room temperature or heated after dotting or dyeing. The beaded hair combs made by the above process have the problem that the beads are easy to fall off, and the production process and products are poor in environmental protection.

[0003] Invention patent CN111134437A discloses a method of making bead heads using flames or flame arrays, which can solve the problem of easy falling off of bead heads and environmental protection. However, the fire source of the flame is generally natural gas, petroleum gas or alcohol, etc., which is dangerous to use in a production workshop. In addition, the pressure stability of the gas has a great influence on the dimensional stability of the product. When the gas pressure is high, the flame is larger and the degree of melting of the plastic wire is high; when the gas pressure is low, the flame is smaller, the heat received by the plastic wire is insufficient, and the degree of melting is low, which easily causes the bead head to be small. The air flow around the equipment can also easily cause the flame to jump, resulting in poor bead head shape, see Figure 2 shown.

[0004] Moreover, most of the beaded hair used in hair combs do not have anti-static function. When combing hair, the comb easily rubs against the hair to generate static electricity, causing discomfort in use. Summary of the invention

[0005] The embodiments of the present invention provide a bead-head wire and a manufacturing method and application thereof, aiming to solve the safety problem in the existing bead-head wire manufacturing process, the problem of poor consistency of bead head shape, and the problem of static electricity generated by the bead-head wire during use.

[0006] The technical solution of the present invention is achieved in this way:

[0007] A method for making a bead-head wire, using a bead-head wire preparation device, comprises the following steps:

[0008] (1) Turn on the red-hot heater and raise the temperature to 200-700°C to form a heating point;

[0009] (2) placing the plastic wire to be processed on a conveying module, and as the conveying module operates, the plastic wire passes through the edge of the heating point of the red-hot heater, and the end of the plastic wire near the heating point is melted into a bead head at high temperature to obtain a bead head wire;

[0010] The bead head wire preparation device includes a conveying module and a reddening heater module. The reddening heater modules are relatively arranged on both sides of the conveying module. When the plastic wire to be processed is placed on the conveying module for transmission, the end of the plastic wire to be processed is arranged opposite to the reddening heater module; the reddening heater module includes at least one group of reddening heaters.

[0011] The plastic wire passes through the edge of the heating point of the red-emitting heater, and specifically, the distance between the end of the plastic wire and the edge of the heating point is 0.5 mm to 10 mm.

[0012] The speed of the plastic wire when passing through the heating point of the red-hot heater is 5-30 m / min.

[0013] According to the different materials and diameters of the plastic wire, the distance between the plastic wire and the edge of the heating point of the red-hot heater, the speed of the plastic wire when passing through the heating point of the red-hot heater and the temperature of the heating point of the red-hot heater are adjusted.

[0014] Preferably, the conveying module includes a conveying motor, a conveyor belt and a loading mold. The conveying motor drives the conveyor belt to transmit. The loading mold is arranged on the conveyor belt and transmits with the conveyor belt. The loading mold is used to place the plastic wire to be processed. When the loading mold passes through the inflammable heater module, the inflammable heater realizes heating treatment on the end of the plastic wire to be processed.

[0015] Further preferably, the charging mold is evenly provided with grooves slightly wider than the diameter of the plastic wire, and during the production and delivery process, the plastic wire falls into the grooves for charging and transporting the plastic wire to be processed.

[0016] Preferably, the red-emitting heater is an electric heater.

[0017] Preferably, in step (1), the temperature is raised to 200-700°C to form a heating point, specifically: 3 groups of red-hot heaters are turned on, the temperature of the first group of red-hot heaters is set to 590-610°C, the end of the brush wire is 1-3mm away from the heating point, and the end of the brush wire is preheated; the temperature of the second group of red-hot heaters is set to 610-630°C, the end of the brush wire is 1-3mm away from the heating point, and the main body of the brush wire end is shaped; the temperature of the third group of red-hot heaters is set to 580-600°C, the end of the brush wire is 4-6mm away from the heating point, and the main body of the brush wire end is shaped to fine-tune the shape of the bead head; this method of forming heating points makes the shape of the bead head more rounded and improves the shape consistency.

[0018] Further preferably, in step (1), the temperature is raised to 200-700°C to form a heating point, specifically: 5 groups of red-hot heaters are turned on, the temperature of the first group of red-hot heaters is set to 440-460°C, the temperature of the second and third groups of red-hot heaters is set to 455-475°C, the temperature of the fourth group of red-hot heaters is set to 450-470°C, and the temperature of the fifth group of red-hot heaters is set to 440-460°C; this method of forming a heating point lowers the set temperature of the red-hot heater, avoids discoloration of the plastic wire due to high temperature, makes the shape of the bead head more rounded, and improves shape consistency.

[0019] Preferably, in step (1), the temperature tolerance of the heating point is controlled between ±5°C.

[0020] Preferably, in step (1), an auxiliary positioning device is installed at the front end of the heating point, and the auxiliary positioning device controls the distance between the end of the brush filament and the heating point to be within the range of 0.5 to 10 mm.

[0021] Preferably, in step (2), a windshield plate with micro-heat dissipation holes is added to the outside of the heating point. By setting the windshield plate with micro-heat dissipation holes, the temperature stability and air flow stability at the heating point can be increased.

[0022] Preferably, in step (2), the plastic filament to be processed is pre-processed into the required length of the bead head filament and then placed on the conveying module.

[0023] Preferably, in step (2), the method for preparing the plastic filament to be processed comprises the following steps:

[0024] 1) Mix the materials evenly according to the ratio of 60-95% plastic raw material, 1%-39.5% antistatic agent, 0.08-0.12% lubricant and 0.3-0.5% masterbatch;

[0025] 2) Add the mixed materials into the extruder hopper, set the extruder temperature at 200°C-300°C, cool them in a 5°C-30°C cold water tank, stretch them at a ratio of 2-6 times, set the molding temperature at 100°C-280°C, and obtain plastic filaments;

[0026] 3) Cut the plastic wire into the required length of the bead wire to obtain the plastic wire to be processed.

[0027] The plastic yarn to be processed obtained by the above-mentioned preparation method solves the problem that the existing bead-head yarn is prone to generate static electricity during use based on the addition of an appropriate amount of precipitation-type antistatic agent.

[0028] Preferably, in step 1), the antistatic agent is at least one of a precipitation type antistatic agent or a permanent antistatic agent; the amount of the precipitation type antistatic agent is preferably 1%-10%, and the amount of the permanent antistatic agent is 5%-39.5%.

[0029] As described above, the present invention solves the static electricity problem by adding a precipitation type antistatic agent or a long-term antistatic auxiliary agent, as follows:

[0030] 1. Add 1%-10% of precipitation-type antistatic additives to the raw materials used for plastic filaments. The raw materials are recycled after melting, extrusion, cooling, heating, stretching and shaping. The recycled plastic filaments are placed in hot steam to promote the migration of the precipitation-type antistatic additives to the surface of the plastic filaments, forming a layered antistatic structure on the surface of the plastic filaments.

[0031] 2. Add 5%-39.5% of long-term antistatic additives to the raw materials used for plastic filaments, and recycle the raw materials after melting, extrusion, cooling, heating, stretching and shaping. Long-term antistatic additives are high molecular weight hydrophilic substances, which are evenly mixed with the plastic raw materials during the melt extrusion process to form a hydrophilic conductive network inside the plastic filaments, promoting the release of charges.

[0032] Preferably, in step (2), after the bead head yarn is prepared, the bead head yarn is placed above 60-100°C hot water for 5-100 minutes for solidification treatment. After the solidification treatment, the bead head of the bead head yarn can adapt to the excessive temperature of 60-100°C, which is more conducive to obtaining the stability of the bead head of the bead head yarn.

[0033] A bead-head silk is prepared by the above-mentioned production method.

[0034] The beaded wire prepared by the present invention is used in daily necessities such as hair combs and massagers; the rounded beaded wire can provide a comfortable combing or massage experience and can effectively achieve an anti-static effect.

[0035] In the present invention, the problem of static electricity easily generated by bead-head wire during use is solved by adding a precipitation-type antistatic agent or a long-lasting antistatic auxiliary agent, the plastic wire is pre-processed into a required length, and one or more heating points with a temperature between 200-700°C are prepared by electric heating, and the temperature tolerance of the heating point is controlled between ±5°C, and a windproof plate with micro heat dissipation holes is added to the outside of the heating point; the plastic wire to be processed is placed on a conveying module and contacted with the conveying module, and grooves slightly wider than the diameter of the brush wire are evenly distributed on the conveying module. During the operation of the conveying module, the plastic wire falls into the grooves, passes through the edge of the heating point through the conveying module, and the plastic wire close to the heating point position melts to form a water drop-shaped bead head, thereby obtaining a bead-head wire.

[0036] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0037] 1. The heating points formed by electric heating are used to melt the plastic wire to be processed to make beaded wire. The safety protection of the windshield with micro heat dissipation holes of the beaded wire preparation device increases the safety of the beaded wire production process.

[0038] 2. The heating point is formed by electric heating, and with the temperature control system, the temperature of the electric heating is stable, the shape and size of the bead head are highly consistent, and it is easy to adjust.
