[0004] However, after the special polyester texturing end-tie device completes the yarn connection, there is a risk of breakage during the transition on the machine due to the unstable knotting node structure. In addition, the end-tie device requires manual thread holding during use, and the length of the thread end cannot be controlled, resulting in waste of polyester material and affecting the working efficiency of the polyester texturing device. Summary of the Invention

[0005] The purpose of this invention is to provide a special polyester texturing and finishing device and method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a special polyester texturing and finishing device, comprising a base, a finishing block fixedly connected to the top of the base, a pad fixedly connected to the inner wall of the finishing block, an arc-shaped groove formed in the inner wall of the pad, an air outlet formed at the bottom of the arc-shaped groove, two sets of air outlets, the two sets of air outlets being equidistantly arranged in the arc-shaped groove with the center line of the finishing block as the array axis, the two sets of air outlets being used to blow air onto the yarn in different directions, and a clamping mechanism being provided inside the finishing block;

[0007] The clamping mechanism includes an electric gripper. The bottom of the electric gripper slides along the inner wall of the tail block. An inductive switch is fixedly connected to the inner wall of the electric gripper. The inductive switch is used to sense the polyester thread, and the electric gripper is used to clamp the polyester thread. The inner wall of the electric gripper has a corrugated surface to increase the friction with the polyester thread. A microcontroller is installed inside the base and is electrically connected to the electric gripper, the inductive switch, and the electric push rod. After the inductive switch senses the polyester thread, it feeds back to control the electric gripper to clamp the thread. At the same time, it controls the electric push rod to drive the guide block to slide on the inner wall of the base. A lithium battery is installed inside the base to power the electric gripper and the electric push rod.

[0008] According to the above technical solution, a baffle is fixedly connected to the bottom of the air outlet groove wall. The baffle is set at the gap between the two sets of air outlets to isolate the airflow blown out of the air outlet. A diverter block is fixedly connected to the inner wall of the base, and an air inlet is fixedly connected to the inner wall of the base. The inside of the diverter block is connected to the air outlet, and the diverter block is fixedly connected to the air inlet. The diverter block is used to guide the gas to the two sets of air outlets. A solenoid valve is set inside the diverter block and electrically connected to a single-chip microcomputer set inside the base to control the opening and closing of the internal passage of the diverter block.

[0009] According to the above technical solution, a support frame is fixedly connected to the outer wall of the electric gripper, and a support wheel is rotatably connected to the inner wall of the support frame via a rotating shaft. The bottom of the support wheel contacts the inner wall of the tail block and rotates along the inner wall of the tail block. The support wheel is used to support the electric gripper through the support frame, and a slot is opened at the bottom of the electric gripper.

[0010] According to the above technical solution, a sliding groove is provided on the inner wall of the tail block. The sliding groove is arc-shaped and is provided on the inner wall of the tail block. There are two sets of sliding grooves. The two sets of sliding grooves are equidistantly provided on the inner wall of the tail block with the center line of the tail block as the array axis. The sliding groove is used to guide the electric gripper.

[0011] According to the above technical solution, the base is provided with a support mechanism, which includes a support rod. The outer wall of the support rod is slidably connected to the wall of the sliding groove. A hinge joint is fixedly connected to the top of the support rod. The hinge joint is hinged to the groove wall through a rotating shaft. The hinge joint is used to guide and support the electric gripper through the groove and limit the electric gripper.

[0012] According to the above technical solution, a guide block two is slidably connected to the inner wall of the base, and a sliding groove two is opened on the inner wall of the guide block two. The groove wall of the sliding groove two is slidably connected to the outer wall of the hinge joint. A spring is fixedly connected to the outer wall of the hinge joint, and the other end of the spring is fixedly connected to the groove wall of the sliding groove two. The guide block two is used to limit the hinge joint, and the spring is used to support the hinge joint.

[0013] According to the above technical solution, a limiting rod is fixedly connected to the outer wall of the second guide block, and a first guide block is slidably connected to the outer wall of the limiting rod. The bottom of the first guide block is slidably connected to the inner wall of the base through a slide rail. The limiting rod is used to limit the second guide block, and the first guide block is used to limit the second guide block through the limiting rod.

[0014] According to the above technical solution, an electric push rod is fixedly connected to the inner wall of the base. The output end of the electric push rod is fixedly connected to the outer wall of the guide block. The electric push rod serves as a power source to drive the guide block to slide on the inner wall of the base. The support rod is guided by the sliding groove and drives the electric gripper to slide along the inner wall of the tail block, so that the electric gripper drives the polyester yarn to switch.

[0015] A method for texturing and finishing special polyester fibers, applicable to the aforementioned special polyester texturing and finishing device, includes the following steps:

[0016] S1. Introduce the two polyester filaments to be connected into the electric gripper area inside the tail block. The position of the filaments is sensed by the induction switch, and the electric gripper is closed by feedback, so that the wavy inner wall of the electric gripper clamps and fixes the two filaments.

[0017] S2. After the yarn is fixed, the electric actuator starts and drives the guide block one to slide along the inner wall of the base. It also drives the guide block two to move synchronously through the limit rod, and drives the support rod to slide along the sliding groove one. The hinge joint at the top of the support rod is hinged to the groove at the bottom of the electric gripper, which drives the electric gripper to slide along the arc-shaped trajectory of the inner wall of the tail block. At the same time, the electric gripper always points to the axis position of the tail block, and drives the two polyester yarns to separate and switch, and then drives the yarns to overlap.

[0018] S3. After the two strands of silk overlap, the solenoid valve in the splitter block opens, and the gas enters the splitter block through the air inlet. After being split, the gas is blown out from the two sets of air outlets in different directions, and the two airflows are isolated by the baffle, so that the silk at the overlapping point rotates in opposite directions to tie a knot.

[0019] S4. After the knot is tied, the electric clamps are released, and the operator removes the connected thread from the device and cuts off any excessively long ends after the knot is tied.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention uses a clamping mechanism to fix polyester filaments and automatically switches between them, allowing the ends of the polyester filaments to overlap and be knotted. This reduces the workload of operators and effectively shortens the length of excess thread after knotting, thus reducing waste of polyester filament materials.

[0022] 2. This invention, by setting an air outlet, blows air into the yarn from two different directions during the knotting process, causing the yarn to rotate and wrap in opposite directions during the knotting process. This increases the strength of the knotted polyester yarn, prevents the yarn from breaking during the texturing process, and improves the stability of the yarn after knotting.

[0023] 3. The present invention guides and supports the electric gripper through a support mechanism, so that the electric gripper can move along the direction away from the axis of the tail block to switch the wires during the wire switching process, and then drive the wires to overlap, thus avoiding interference between the electric gripper and the wires during the movement and improving the stability of the tail device during the knotting process.

[0024] 4. The present invention limits the electric gripper by a support mechanism, ensuring that the electric gripper slides stably along the inner wall of the tail block and drives the yarn to switch, preventing the electric gripper from rotating during the sliding process, which would cause the polyester yarn to shift position, ensuring that the yarn overlaps and is knotted, and improving the stability of the tail device during yarn switching and knotting.

Detailed Implementation

[0036] 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.

[0037] Example 1, please refer to Figures 1-8 The present invention provides a technical solution: a special polyester texturing and finishing device, including a base 100, a finishing block 102 fixedly connected to the top of the base 100, a pad 103 fixedly connected to the inner wall of the finishing block 102, an arc-shaped groove 105 opened on the inner wall of the pad 103, an air outlet 106 opened at the bottom of the groove wall of the arc-shaped groove 105, and two sets of air outlets 106 are arranged equidistantly in the arc-shaped groove 105 with the center line of the finishing block 102 as the array axis. The two sets of air outlets 106 are used to blow air onto the yarn in different directions. A clamping mechanism 200 is provided inside the finishing block 102.

[0038] After the special polyester texturing end-tie device completes the yarn connection, there is a risk of breakage during the transition on the machine due to the unstable knotting node structure. Furthermore, the end-tie device requires manual yarn holding, and the length of the yarn end cannot be controlled, leading to waste of polyester material and affecting the working efficiency of the polyester texturing device. Therefore, a clamping mechanism 200 is set up to clamp the yarn and automatically switch to ensure the end-tie yarns overlap before knotting, reducing the workload of the workers and decreasing the length of the excess yarn end after knotting, thus reducing waste of polyester yarn material. Simultaneously, through the air outlet 106, air is blown into the yarn in two different directions during knotting, causing the yarn to rotate in opposite directions to knot, increasing the stability of the knot and preventing breakage during texturing, thus increasing the stability of the knotted yarn.

[0039] The clamping mechanism 200 includes an electric gripper 201. The bottom of the electric gripper 201 slides along the inner wall of the tail block 102. An inductive switch 202 is fixedly connected to the inner wall of the electric gripper 201. The inductive switch 202 is used to sense the polyester filament, and the electric gripper 201 is used to clamp the polyester filament. The inner wall of the electric gripper 201 has a corrugated surface to increase the friction with the polyester filament. A microcontroller is installed inside the base 100 and is electrically connected to the electric gripper 201, the inductive switch 202, and the electric push rod 302, so that the inductive switch 202 senses the polyester filament. Subsequently, the feedback control electric gripper 201 clamps the wire, while simultaneously controlling the electric push rod 302 to drive the guide block 301 to slide on the inner wall of the base 100. A lithium battery is installed inside the base 100 to power the electric gripper 201 and the electric push rod 302. A stop block 107 is fixedly connected to the bottom of the air outlet 106 groove wall, positioned at the gap between the two sets of air outlets 106 to isolate the airflow from the air outlets 106. A diverter block 108 is fixedly connected to the inner wall of the base 100. [Further details about the stop block and the inner wall are not provided in the original text.] The air inlet 101 and the flow divider 108 are connected to the air outlet 106. The flow divider 108 is fixedly connected to the air inlet 101 and is used to guide the gas to the two sets of air outlets 106. A solenoid valve is installed inside the flow divider 108 and is electrically connected to a single-chip microcomputer installed inside the base 100 to control the opening and closing of the internal passage of the flow divider 108. A support frame 203 is fixedly connected to the outer wall of the electric gripper 201. A support wheel 204 is rotatably connected to the inner wall of the support frame 203 through a rotating shaft. The bottom of the support wheel 204 is connected to the tail block 10. The inner wall contacts the electric gripper 201 and it rotates along the inner wall of the tail block 102. The support wheel 204 is used to support the electric gripper 201 through the support frame 203. The bottom of the electric gripper 201 is provided with a slot 205. The inner wall of the tail block 102 is provided with a sliding groove 104. The sliding groove 104 is arc-shaped and is provided on the inner wall of the tail block 102. There are two sets of sliding grooves 104. The two sets of sliding grooves 104 are equally spaced on the inner wall of the tail block 102 with the center line of the tail block 102 as the array axis. The sliding groove 104 is used to guide the electric gripper 201.

[0040] When the special polyester texturing and finishing device is put into use, after connecting the air inlet 101 to the air source, the operator places the polyester filament tail and the next set of polyester filament head into the electric gripper 201 through the finishing block 102. After the induction switch 202 senses the filament, it receives feedback and causes the electric gripper 201 to clamp the filament. The electric push rod 302 then drives the guide block 301 to slide on the inner wall of the base 100. The guide block 301, through the limit rod 303, drives the guide block 304 to slide synchronously with the guide block 301 on the inner wall of the base 100. 304 drives the support rod 305 to slide within the sliding groove 104, guiding the support rod 305 through the sliding groove 104. The support rod 305, via the hinge joint 306, drives the electric gripper 201 to slide along the inner wall of the tail block 102, causing the electric gripper 201 to leave the support of the pad block 103 and drive the wire to slide towards the other end of the sliding groove 104, switching the wire and aligning the two wires. During the switching process, while the electric gripper 201 slides along the inner wall of the tail block 102, the support wheel 204 supports the electric gripper 201. The support, rolling on the inner wall of the tail block 102, guides and supports the electric gripper 201. Simultaneously, the electric gripper 201 is limited by the support rod 305, causing it to slide against the pad 103 and then contact the inner wall of the tail block 102 after leaving the pad 103 support. This allows the electric gripper 201 to move the wire away from the axis of the tail block 102 for switching. At the same time, the electric gripper 201, in contact with the inner wall of the tail block 102, tilts and points towards the axis of the tail block 102, preventing the electric gripper 201 from isolating the wire after switching, thus preventing the two sets of wires from overlapping. Then, the solenoid valve inside the diverter block 108 opens the control channel to divert and guide the gas to two sets of air outlets 106 to blow air onto the yarn and tie it. The two sets of air outlets 106 blow air onto the yarn in different directions. The gas is isolated by the baffle block 107, so that the two streams of gas generate a swirling flow in the tail block 102, which drives the yarn to rotate in opposite directions to tie it. This increases the stability of the polyester yarn knot and prevents the yarn knot from breaking during the texturing process, which would cause the equipment to stop. After the yarn knot is completed, the electric gripper 201 is opened to take out the yarn and the excess yarn ends are cut off.

[0041] Example 2, based on Example 1, please refer to... Figures 9-10 The present invention provides a technical solution: a support mechanism 300 is provided inside the base 100;

[0042] When the clamping mechanism 200 drives the wire to switch and make the wire overlap for knotting, the electric gripper 201 interferes with the wire, which can easily cause the wire to fail to overlap. Therefore, a support mechanism 300 is set to guide and support the electric gripper 201, so that the electric gripper 201 can move away from the axis of the tail block 102 to switch the wire and then drive the wire to overlap. This prevents the electric gripper 201 from interfering with the wire during the switching process, which would cause the wire to fail to overlap for knotting. This increases the stability of the tail device for knotting the wire. At the same time, the support mechanism 300 limits the electric gripper 201, so that the electric gripper 201 can slide stably on the inner wall of the tail block 102 to drive the wire to switch. This prevents the electric gripper 201 from rotating during the process of sliding on the inner wall of the tail block 102 to drive the wire to switch, which would cause the wire to deviate and fail to overlap for knotting. This increases the stability of the tail device for switching and knotting the wire.

[0043] The support mechanism 300 includes a support rod 305, the outer wall of which is slidably connected to the wall of the sliding groove 104. A hinge joint 306 is fixedly connected to the top of the support rod 305. The hinge joint 306 is hinged to the wall of the slot 205 via a rotating shaft. The hinge joint 306 is used to guide and support the electric gripper 201 through the slot 205 and to limit the electric gripper 201. A guide block 204 is slidably connected to the inner wall of the base 100. A sliding groove 207 is formed on the inner wall of the guide block 204. The wall of the sliding groove 207 is slidably connected to the outer wall of the hinge joint 306. A spring 308 is fixedly connected to the outer wall of the hinge joint 306. The other end of the spring 308 is fixedly connected to the wall of the sliding groove 207. The guide block 204 is used to limit the hinge joint 306, and the spring 308 is used to limit the hinge joint 306. The connector 306 provides support. A limit rod 303 is fixedly connected to the outer wall of the guide block 2 304. A guide block 1 301 is slidably connected to the outer wall of the limit rod 303. The bottom of the guide block 1 301 is slidably connected to the inner wall of the base 100 via a slide rail. The limit rod 303 is used to limit the guide block 2 304. The guide block 1 301 is used to limit the guide block 2 304 via the limit rod 303. An electric push rod 302 is fixedly connected to the inner wall of the base 100. The output end of the electric push rod 302 is fixedly connected to the outer wall of the guide block 1 301. The electric push rod 302 serves as a power source to drive the guide block 1 301 to slide on the inner wall of the base 100. The support rod 305 is guided by the sliding groove 104 and drives the electric gripper 201 to slide along the inner wall of the tail block 102, so that the electric gripper 201 drives the polyester yarn to switch.

[0044] After the electric gripper 201 clamps the polyester yarn, the electric actuator 302 drives the guide block 1 301 to slide on the inner wall of the base 100. The guide block 1 301 drives the guide block 2 304 to slide synchronously with the guide block 1 301 inside the base 100 through the limiting rod 303. This causes the guide block 2 304 to drive the support rod 305 to slide in the sliding groove 104. The support rod 305 drives the electric gripper 201 to slide on the inner wall of the tail block 102 through the hinge joint 306, switching the yarn. During the sliding of the support rod 305 in the sliding groove 104, the guide block 2 304 is limited by the limiting rod 303, which in turn drives the limiting rod 303 to slide on the inner wall of the guide block 1 301 to compensate for the displacement of the guide block 2 304. This allows the limiting rod 303 to limit the guide block 2 304, preventing the guide block 2 304 from moving. The 04-degree angle offset causes the support rod 305 to rotate. The support rod 305 is limited by the sliding groove 307 to prevent it from rotating during sliding within the sliding groove 104, thus fixing the direction of the electric gripper 201. The support rod 305 is guided by the sliding groove 104 and drives the electric gripper 201 to slide along the inner wall of the tail block 102 via the hinge joint 306. The hinge joint 306 supports the support rod 305 through the spring 308, limiting the electric gripper 201 and causing it to fit against the inner wall of the tail block 102. During the process of the electric gripper 201 sliding along the inner wall of the tail block 102 and switching the wires, the electric gripper 201 remains pointing towards the axis of the tail block 102, preventing interference with the wires and causing them to fail to overlap.

[0045] A method for texturing and finishing special polyester fibers, applicable to special polyester texturing and finishing devices, includes the following steps:

[0046] S1. The two polyester filaments to be connected are introduced into the area of ​​the electric gripper 201 in the tail block 102. The position of the filaments is sensed by the induction switch 202, and the electric gripper 201 is closed by feedback, so that the wavy inner wall of the electric gripper 201 clamps and fixes the two filaments.

[0047] S2. After the yarn is fixed, the electric push rod 302 is started and drives the guide block 1 301 to slide along the inner wall of the base 100. The limit rod 303 drives the guide block 2 304 to move synchronously and drives the support rod 305 to slide along the sliding groove 104. The hinge joint 306 at the top of the support rod 305 is hinged to the slot 205 at the bottom of the electric gripper 201, which drives the electric gripper 201 to slide along the arc-shaped trajectory of the inner wall of the tail block 102. At the same time, the electric gripper 201 always points to the axis position of the tail block 102, and drives the two polyester yarns to separate and switch, and then drives the yarns to overlap.

[0048] S3. After the two strands of silk overlap, the solenoid valve in the diverter block 108 opens, and the gas enters the diverter block 108 through the air inlet 101. After being diverted, the gas is blown out from the two sets of air outlets 106 in different directions, and the two airflows are isolated by the baffle block 107, so that the silk at the overlap point rotates in opposite directions to tie a knot.

[0049] S4. After the knot is tied, the electric clamp 201 is released, and the operator takes the connected thread out of the device and cuts off the excessively long thread ends after knotting.

[0050] 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 claims and their equivalents.
