Technical Field

[0001] This invention relates to the field of silk threads, and in particular to a process for preparing gold and silver threads. Background Technology

[0002] The production of gold and silver threads primarily utilizes polyester film as a base, employing vacuum coating technology to form the threads. These threads require uniform fineness, bright color, good colorfastness, high strength, no knife marks, and resistance to acids, alkalis, soaping, and abrasion. They are widely used in the crafts, fashion, embroidery, and gift packaging industries, as well as in the processing of yarn, knitted fabrics, warp-knitted fabrics, woven fabrics, garment accessories, and decorative fabrics, making them ideal lining materials.

[0003] The preparation of gold and silver wire involves using physical methods to cut colored polyester films into extremely fine filaments. However, most existing preparation processes can only perform single-blade cutting, resulting in low cutting efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a process for preparing gold and silver wires that can cut wires simultaneously using two cutters, resulting in high cutting efficiency.

[0005] The objective of this invention is achieved through the following technical solution:

The two drive wheels are respectively connected to the two rotating seats, and the key shaft is slidably connected to the two drive wheels via a key.

[0014] The shredding device also includes a bracket fixed to the rear end of the base, a bidirectional screw II rotating on the bracket, two threaded seats threaded to both ends of the bidirectional screw II, and two cutters respectively connected to the two threaded seats.

[0015] A crossbar runs through the rear ends of the two cutters. A screw is threaded into the middle of the crossbar. A square seat rotates at the lower end of the screw and slides back and forth in the middle of the bracket.

[0039] like Figure 1-13 As shown:

[0040] A process for preparing gold and silver wire includes the following steps:

[0041] S1. Vacuum deposit metal onto a polyester film, and then coat it with a transparent resin protective layer to obtain the base material film;

[0042] S2. Wind the base material film into a roll and install it on the shredder;

[0043] S3. The two cutters 303 of the slicing device simultaneously slicing the film roll of the base material into shreds at both ends;

[0044] S4. Simultaneously, the silk threads are wound and collected to obtain gold and silver threads.

[0045] The metal used in step S1 is an aluminum alloy.

[0046] like Figure 2-13 As shown:

[0047] The shredding device includes a base 101, a first transverse groove 103, a bidirectional screw I 201, side support plates 202, rotating seats 203, and cone heads 204. The base 101 is provided with a first transverse groove 103 in the transverse direction. The two side support plates 202 slide symmetrically in the first transverse groove 103. The two rotating seats 203 are respectively rotatably connected to the upper ends of the two side support plates 202. The two cone heads 204 are respectively fixed to the inner side of the two rotating seats 203. The bidirectional screw I 201 rotates laterally in the first transverse groove 103. The two side support plates 202 are respectively threaded to the two ends of the bidirectional screw I 201.

[0048] When installing the basic raw material film roll on the shredding device, align the two ends of the central hole of the basic raw material film roll with the two cones 204, and then rotate the bidirectional screw I 201, so that the bidirectional screw I 201 simultaneously drives the two side support plates 202 to move closer and closer, thereby driving the two cones 204 to approach and insert into the central hole of the basic raw material film roll. Due to the cone shape of the cones 204, when the cones 204 are inserted into the central hole of the basic raw material film roll, they can automatically center the basic raw material film roll until the two cones 204 press against the two ends of the central hole of the basic raw material film roll, thus completing the fixation of the basic raw material film roll and ensuring that the basic raw material film roll and the two cones 204 are coaxial, thereby ensuring the degree of shredding by the cutter 303 during shredding.

[0049] Furthermore, by simultaneously bringing the two side support plates 202 close together to fix the base material film roll, the shredding device can adapt to fixing base material film rolls of different widths.

[0050] like Figure 2-13 As shown:

[0051] The shredding device also includes a key shaft 205 and transmission wheels 206; the key shaft 205 rotates at the rear end of the base 101, and the two transmission wheels 206 rotate at the rear ends of the two side support plates 202 respectively. The two transmission wheels 206 are respectively connected to the two rotating seats 203 for transmission. The key shaft 205 and the two transmission wheels 206 are slidably connected by a key.

[0052] By installing a first motor on the base 101, the first motor drives the key shaft 205. The rotating key shaft 205 can simultaneously drive two transmission wheels 206 to rotate via the key, which in turn drives two rotating seats 203 to rotate simultaneously via the two transmission wheels 206, which in turn drives the basic raw material film roll to rotate via the cone head 204, thereby cooperating with two cutters 303 to complete the slicing.

[0053] By having two transmission wheels 206 slide on the key shaft 205, the key shaft 205 ensures synchronous transmission to the two rotating seats 203.

[0054] like Figure 2-13 As shown:

[0055] The shredding device also includes a bracket 104, a bidirectional screw II 301, a threaded seat 302, and a cutter 303; the bracket 104 is fixed to the rear end of the base 101, the bidirectional screw II 301 rotates on the bracket 104, the two threaded seats 302 are respectively threaded to both ends of the bidirectional screw II 301, and the two cutters 303 are respectively connected to the two threaded seats 302.

[0056] By setting up the bidirectional screw II 301 and the two threaded seats 302, two cutters 303 are installed, so that the blades of the two cutters 303 can be aligned with the base material film roll to cut the base material film roll into shreds. Moreover, by setting up two cutters 303, both ends of the base material film roll can be cut into shreds at the same time, which greatly improves the shredding efficiency.

[0057] By rotating the bidirectional screw II 301, the two threaded seats 302 can be driven to move closer or further apart, thereby driving the two cutters 303 to move closer or further apart, thus changing the distance between the two cutters 303 to adapt to the cutting of film rolls of different widths.

[0058] Furthermore, since the basic raw material film roll is clamped by two adjacent side support plates 202, it is ensured that the basic raw material film roll is in the middle position of the slicing device. Thus, the position of the two cutters 303 is driven by the bidirectional screw II 301, ensuring that the two cutters 303 can be aligned with both ends of the basic raw material film roll at the same time, and ensuring that the two cutters 303 have the same cutting degree.

[0059] Further:

[0060] A crossbar 304 is connected through the rear ends of the two cutters 303. A screw 305 is threadedly connected to the middle of the crossbar 304. A square seat 306 rotates at the lower end of the screw 305 and slides in the middle of the bracket 104 in the front-back direction.

[0061] A second motor is installed inside the square base 306, which drives the screw 305 to rotate. The rotating screw 305 can drive the crossbar 304 through the thread, thereby changing the distance between the crossbar 304 and the square base 306. In turn, the crossbar 304 drives the two cutters 303 to rotate on the two threaded seats 302, thereby changing the distance between the blades of the two cutters 303 and the axis of the base material film roll, so as to ensure the synchronous feeding of the two cutters 303.

[0062] like Figure 2-13 As shown:

[0063] The second transverse groove 102 is horizontally arranged at the front end of the base 101. The reciprocating shaft 401 rotates within the second transverse groove 102, and the support 402 slides within the second transverse groove 102. The support 402 is slidably connected to the reciprocating groove on the reciprocating shaft 401, and two winding mechanisms are symmetrically connected to both ends of the support 402.

[0064] Since the two cutters 303 cut the shreds simultaneously, the shreds are simultaneously wound and collected by two winding mechanisms.

[0065] A third motor mounted on the base 101 drives the reciprocating shaft 401. The rotating reciprocating shaft 401 can move back and forth in the second transverse groove 102 through the reciprocating groove drive support 402, thereby forming a regular arrangement of the shredded wire and ensuring that the shredded wire can form neat gold and silver wire rolls after winding.

[0066] Further:

[0067] The winding mechanism includes a winding frame 501, a circular seat 502, a limiting groove 503, and a clamping plate 505. The winding frame 501 rotates at the end of the support 402. A torsion spring is provided between the support 402 and the winding frame 501 to make the winding frame 501 perpendicular to the support 402 and press against the support 402. The circular seat 502 rotates inside the winding frame 501. Three limiting grooves 503 are evenly distributed and pass through the circular seat 502. Three clamping plates 505 slide in the three limiting grooves 503 respectively.

[0068] When winding the gold and silver wires obtained from slicing, the winding core is placed on three clamping plates 505, and the three clamping plates 505 move simultaneously away from the center of the round seat 502 within the three limiting grooves 503 to clamp and fix the winding core. Moreover, since the three clamping plates 505 are relatively long, they can adapt to winding at different slicing positions.

[0069] The winding frame 501 is equipped with a fourth motor, which drives the round seat 502 to rotate the three clamps 505, which in turn drives the winding core sleeve on them to rotate, thus completing the winding of the gold and silver wire.

[0070] Meanwhile, in order to ensure that the positions of the two winding core sleeves can adapt to the shaving and winding at different positions, the gap between the inner ends of the two sets of clamping plates 505 connected to the two round seats 502 is small, thus ensuring the installation of the winding core sleeves on the two sets of clamping plates 505. However, when installing the winding core sleeve on the clamping plate 505, it is necessary to push the winding frame 501 to overcome the elastic force of the torsion spring and rotate it on the support 402, so that the end of the clamping plate 505 on that side is exposed. Then, the winding core sleeve is put on the three clamping plates 505 to complete the installation of the winding core sleeve on that side. Then, the winding frame 501 is released, and the elastic force of the torsion spring will automatically push the winding frame 501 to rotate, making the installation of the winding core sleeve convenient and quick.

[0071] Further:

[0072] The conical shaft 601 slides through the winding frame 501, and the spring 602 is disposed between the conical shaft 601 and the winding frame 501, so that the conical end of the conical shaft 601 is inserted into the center of the round seat 502 and squeezes the three clamping plates 505 to slide away.

[0073] The spring force of the spring 602 pushes the cone end of the push cone shaft 601 into the center of the round seat 502, and then simultaneously squeezes the three clamping plates 505 at the center of the round seat 502, so that the three clamping plates 505 move away from the center of the round seat 502 at the same time, and clamps and fixes the winding core sleeve.

[0074] During installation, the conical shaft 601 can be pulled outward to overcome the elastic force of the spring 602 and slide outward to the round seat 502, so that the three clamping plates 505 can be gathered together, which makes it easier to wind the core sleeve onto the three clamping plates 505.

[0075] The circular seat 502 has a central hole in the center to facilitate the insertion of the conical shaft 601. The clamping plate 505 consists of a limiting section that slides in the limiting groove 503, a clamping section for clamping the winding core sleeve, and an inclined section for connecting the limiting section and the clamping section. By the inclined section matching the taper of the conical head of the conical shaft 601, the conical shaft 601 presses against the inclined section, so that the clamping section clamps the winding core sleeve.

[0076] Further:

[0077] The collar 504 rotates on the conical shaft 601 and the winding frame 501.

[0078] By setting the collar 504, when the round seat 502 drives the clamping plate 505 to rotate, the collar 504 can rotate on the winding frame 501, ensuring smooth rotation.
