Description

Technical Field

[0001] This invention relates to the field of gold and silver wire technology, specifically to a gold and silver wire production process, related equipment, and gold and silver wire. Background Technology

[0002] Application publication number CN102041563A discloses a method for producing acid and alkali resistant gold and silver wire, comprising the following steps: vacuum aluminizing a polyester film; slitting and micro-cutting the aluminized film into flat filaments; coating the flat filaments with thermosetting resin; applying the resin through a scraper; and finally heating and drying to obtain a gold and silver wire in which the aluminized flat filaments are completely encapsulated in a protective resin layer. The gold and silver wire produced using this invention exhibits good acid and alkali resistance, low fineness, and a smooth hand feel.

[0003] The above solution makes the gold and silver wire resistant to acids and alkalis by adding thermosetting resin and drying it. However, the resin itself has a relatively low melting point, and heating and drying will prolong the solidification speed of the resin, affecting the subsequent winding and processing of the gold and silver wire.

[0004] In addition, due to cost constraints, most gold and silver threads use polyester electroplated yarns. These yarns are brittle and easily broken. Even after the addition of additives, although the yarns have a certain degree of extensibility, they will deform and change in thickness. If the gold and silver threads are wrapped too tightly during the twisting process, they are prone to breakage. Furthermore, it is difficult to guarantee the elasticity of the composite yarn. If it is too loose, the quality of the yarn will be low and the adhesion between the gold and silver threads and the yarn will be too low, affecting the subsequent fabric production process.

[0005] Therefore, in order to address the above problems, the present invention provides a gold and silver wire production equipment and corresponding production process to produce a gold and silver wire to solve the above problems. Summary of the Invention

[0020] Furthermore, the air dryer includes a copper column with heat sinks on its surface and a fan mounted on one side of the heat sinks.

[0021] The copper column has a through hole in the middle for gold and silver wires to pass through.

[0022] A twisting device for producing gold and silver wire includes the above-mentioned coating device for producing gold and silver wire, a take-up reel, and a yarn roller. The take-up reel and the yarn roller are installed at both ends of a track support. A drying device and a twister are provided between the take-up reel and the yarn roller.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] There are several types of gold and silver threads. M-type gold and silver thread is a flat thread, which is made by dyeing polyester film and then cutting it into gold and silver thread slices of the required width and thickness. MX type is made by bidirectionally binding a single gold and silver thread slice with nylon, polyester, rayon, artificial cotton or other types of yarn and then twisting it. MH type gold and silver thread is made by twisting a single gold and silver thread slice with 75d polyester, nylon or rayon or other yarns. This invention provides a production process for MX type and MH type gold and silver threads and proposes a matching twisting equipment for production.

[0053] like Figure 1 - Figure 7 As shown, the present invention provides a technical solution: a gold and silver wire production process, step one: preparing raw materials, including an appropriate amount of gold and silver wire and yarn with excellent tensile strength, etc.

[0054] Step 2: Add thermosetting resin to the coating component 6 of the twisting device for producing gold and silver wire, heat the thermosetting resin material, and add appropriate amount of gelatin to the material to ensure the elasticity of the thermosetting resin material after solidification.

[0055] Step 3: Install the gold and silver wires in the coating device used for gold and silver wire production;

[0056] Step 4: Install the yarn into the twisting device used for producing gold and silver wire;

[0057] Step 5: The gold and silver wires and yarn are twisted together using a gold and silver wire twisting device. During the twisting process, it is necessary to ensure that the surface of the gold and silver wires is coated with thermosetting resin.

[0058] A twisting device for producing gold and silver wire includes a track support 1, with a take-up reel 3 and a yarn roller 5 respectively arranged at both ends of the track support 1, and a coating component 6, a drying device 7 and a twister 8 installed on the track support 1 between the take-up reel 3 and the yarn roller 5.

[0059] The coating component 6 is located near the yarn roller 5, the twister 8 is located near the take-up reel 3, and the drying device 7 is located between the coating component 6 and the twister 8. When using this device, the yarn is wound up by the take-up reel 3 and the yarn roller 5. During this process, the gold and silver wires are wrapped around the yarn by the cooperation of the coating components 6 on both sides and the twister 8. During the twisting process of the gold and silver wires and the yarn, the coating component 6 automatically coats the surface of the gold and silver wires with resin, and the resin dries during this process.

[0060] The coating component 6 includes a fixed bracket 601, with a resin coating element disposed in the middle of the fixed bracket 601. The resin coating element includes a collection box 605 mounted on the fixed bracket 601. A guide tube 608 is fixed to one side of the collection box 605, and a heating tower 607 is fixed to one end of the guide tube 608. The heating tower 607 is connected to the interior of the guide tube 608. A conduit is fixed to one end of the guide tube 608 inside the collection box 605, and a discharge ring 610 is fixed to the end of the conduit. The end of the conduit is connected to the discharge ring 610. The resin is heated by the heating tower 607 and flows through the guide tube 608 into the conduit, overflowing from the discharge ring 610. When the gold and silver wires pass through the discharge ring 610, they are automatically coated with the molten resin, thus achieving resin coating. The diameter of the discharge ring 610 is slightly larger than the diameter of the gold and silver wires, which can achieve resin coating while avoiding excessive resin waste. The collection box 605 can collect excess overflowing resin for recycling and avoid waste.

[0061] A feed roller 614 is provided on one side of the resin-coated part, and a dryer 602 for accelerating resin solidification is provided on the other side of the resin-coated part. The function of the dryer 602 is to pre-dry the resin on the gold and silver wires to prevent the resin from being too fluid and sticking to the equipment and yarn.

[0062] To ensure the smooth implementation of this embodiment, it is necessary to understand that a side frame 613 is fixed to the end of the fixed bracket 601, and a feed roller 614 is rotatably connected to one side of the side frame 613. The feed roller 614 is used for feeding and taking in the gold and silver wires. When the yarn is taken in by the take-up reel 3, the gold and silver wires will also be gradually pulled out of the feed roller 614. A right-angle limiting rod 615 for limiting the gold and silver wires is fixed at the top of the fixed bracket 601 between the collection box 605 and the feed roller 614. The right-angle limiting rod 615 is used to limit the movement path of the gold and silver wires. The right angle of the right-angle limiting rod 615 coincides with the wire hole 611. After the gold and silver wires pass through the right-angle limiting rod 615, they cooperate with the limiting wheel 606 to pass through the wire hole 611 horizontally and smoothly.

[0063] To ensure the smooth implementation of this embodiment, it is necessary to understand that two side rods are fixed between the two sides of the collection box 605 and the fixed bracket 601. Each of the two side rods on both sides has a rotatable limit wheel 606. The middle surface of each of the two limit wheels 606 is provided with an annular groove that matches the gold and silver wire. The limit wheel 606 is also used to limit the movement path of the gold and silver wire, so that the gold and silver wire can stably pass through the wire hole 611. The annular groove on the limit wheel 606 can prevent the gold and silver wire from falling off the limit wheel 606. The collection box 605 has wire holes 611 on both sides. The center of the wire hole 611 is on the same axis as the center of the circle in the cross section of the limit wheel 606. The wire holes 611 on both sides can allow the gold and silver wire to pass through the discharge ring 610, so that the gold and silver wire can be well coated with resin.

[0064] To ensure the smooth implementation of this embodiment, it is necessary to understand that the heating tower 607 is an electrically heated hollow tower body. The top of the heating tower 607 is provided with a screw-on feeding cover. A valve stem 609 is screwed to the end of the guide tube 608 away from the collection box 605. A valve head for controlling the opening and closing of the guide tube 608 is also fixed at one end of the valve stem 609.

[0065] To ensure the smooth implementation of this embodiment, it is necessary to understand that the dryer 602 includes a copper column with heat sinks on its surface and a fan installed on one side of the heat sinks. A through hole is opened in the middle of the copper column for gold and silver wires to pass through. After the gold and silver wires are coated with resin, since the resin has relatively high fluidity and has not yet solidified, the dryer 602 acts as a heat sink. During the process of the gold and silver wires passing through the dryer 602, the heat of the resin is carried away by the dryer 602, allowing the resin to accelerate towards a solidified state, reducing the fluidity of the resin, and better coating the surface of the gold and silver wires.

[0066] To ensure the smooth implementation of this embodiment, it is necessary to understand that the fixed bracket 601 is "L" shaped, the collection box 605 is located on the bottom plane, the air dryer 602 is located on the side plane, and two side rods are also fixed at the bottom of the side plane of the fixed bracket 601. The two side rods are also rotatably connected to the limit wheel 606. The center of the circle on the cross section of the limit wheel 606 is on the same axis as the center of the cross section of the through hole on the air dryer 602.

[0067] A limiting hole 604 is provided at the top of the side plane of the fixed bracket 601. A wire-carrying wheel 603 is provided between the limiting hole 604 and the dryer 602. The wire-carrying wheel 603 is installed on the fixed bracket 601 through the two sides.

[0068] To ensure the smooth implementation of this embodiment, it is necessary to understand that the drying device 7 includes a base 701, and two rows of nozzles 702 are fixedly connected to the top of the base 701. The air outlets of the two rows of nozzles 702 are both set towards the path of the yarn. A fan 703 connected to the inside of the base 701 is also provided on one side of the base 701. The yarn is twisted with the gold and silver wires between the take-up reel 3 and the yarn roller 5. When passing through the drying device 7, the fan 703 provides a large amount of flowing air to dry the resin on the surface of the gold and silver wires. The dried resin solidifies and wraps around the surface of the yarn. The structural design of the two rows of nozzles 702 can ensure that the gold and silver wires are fully dried.

[0069] To ensure the smooth implementation of this embodiment, it is necessary to understand that the twister 8 includes a support plate 801, with a hole at the top of the support plate 801. A twisting member 802 is rotatably connected to the inner wall of the hole. Two connecting shafts 803 rotate on the other side of the support plate 801. One of the connecting shafts 803 is fixed to the twisting member 802. The twisting member 802 allows the yarn and the gold and silver threads to wrap around each other well, achieving twisting. The twisting member 802 is driven by a motor 805, which drives the connecting shaft 803 to rotate, thereby achieving the rotation of the twisting member 802.

[0070] The two connecting shafts 803 are connected by a transmission belt 804, and a motor 805 for driving one of the connecting shafts 803 is installed on one side of the support plate 801.

[0071] To ensure the smooth implementation of this embodiment, it is necessary to understand that the twisting member 802 is composed of four hollow tubes that are self-wound and connected around the same axis, and the four tubes share a common outlet. Before use, the yarn is passed through one of the tubes of the twisting member 802, and then the gold and silver wires are passed through the other tubes in sequence and pulled out at the other end. In this way, when the twisting member 802 rotates and the yarn is pulled by the take-up reel 3, the gold and silver wires can be stably wrapped around the yarn, thus realizing the twisting action.

[0072] To ensure the smooth implementation of this embodiment, it is necessary to understand that T-shaped grooves are provided on the top and both sides of the track support 1, a connecting block 612 is provided at one end of the coating component 6, an embedding strip 704 is provided at the bottom of the air drying device 7, and an insert block 806 is fixed at the bottom of the support plate 801 of the twister 8. The connecting block 612, the embedding strip 704 and the insert block 806 are all inserted into the T-shaped groove of the track support 1. This structural design allows the overall layout and placement of the device to be adjusted, and the coating component 6 can be replaced and maintained at any time, which is simple and efficient.

[0073] To ensure the smooth implementation of this embodiment, it is necessary to understand that a mounting base 2 is installed at one end of the track support 1, the take-up reel 3 rotates on the top of the mounting base 2, and a drive source for driving the take-up reel 3 to rotate is installed inside the mounting base 2. A pay-off support 4 is installed at the other end of the track support 1, and the yarn roller 5 rotates between the two sides of the pay-off support 4. The gold and silver wire adopts the above-mentioned gold and silver wire production process and the twisting device for gold and silver wire production.

[0074] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended embodiments and their equivalents.
