Description

Technical Field

[0001] This invention belongs to the field of medical supplies technology, and specifically relates to an automatic silk weaving device. Background Technology

[0002] A fineness measuring machine is used to extract raw silk linear density (fineness) samples. After extraction, the samples need to be segmented and braided on the machine's spool frame. This braiding prevents the bundled samples from becoming loose or tangled during transport. Typically, a bundle of samples needs to be braided at five locations, with each location requiring 4-6 smaller bundles. Currently, sample braiding is done manually using soft thread, which is labor-intensive, resource-intensive, and inefficient. Therefore, an automatic braiding device needs to be designed to address this issue. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention provides an automatic silk weaving device that enables automated weaving of silk on a silk spool frame.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic silk weaving device includes a support frame, a base, a transverse moving platform, a longitudinal moving platform, partition plates, sliding blocks, a rotary motor, a rotating head, a hot-melt plate, a cutting device, a take-up and undo device, a connecting plate, a thread channel, an electric cylinder, and a thread spool frame. The support frame has a base, on which the transverse moving platform is slidably mounted. The longitudinal moving platform is slidably mounted on the transverse moving platform. A row of partition plates is located at the front end of the longitudinal moving platform. A sliding block is slidably mounted on each partition plate, and a rotating head is connected to the front end of each sliding block via the rotary motor. A hot-melt plate is located on the front face of the rotating head. The rotating head contains a cutting device and a take-up and undo device, with the cutting device located in front of the take-up and undo device. The rear end of each sliding block on the partition plate is fixedly mounted on the connecting plate. The electric cylinder is fixedly mounted on the longitudinal moving platform, and its front end is fixedly connected to the connecting plate. A row of thread spool frames is located on the longitudinal moving platform. The thread channel runs through the connecting plate, sliding blocks, rotating head, and hot-melt plate.

[0006] The automatic silk weaving device designed in this invention uses plastic binding wire to separate (weave) the silk. After the plastic binding wire binds the silk, the two ends that come into contact are connected together by a hot melt plate set at the front end of the rotating head. This realizes the automatic weaving of silk on the silk bobbin frame of the fineness measuring machine, thus speeding up the work efficiency.

[0007] Furthermore, the front end of the separator plate is set as a pointed tip; the front end of the rotating head is located behind the pointed tip. The separator plate is mainly used to divide the silk into several small strands to facilitate the subsequent weaving of the silk, so the rotating head cannot be flush with the pointed tip.

[0008] Furthermore, the rotating head has a right angle. After two adjacent rotating heads rotate relative to each other, their front ends come into contact with each other. That is, the rotating head can only rotate 90 degrees to the left and right. After rotation, the front ends of the rotating heads will come into contact with each other, so that the ends of the plastic binding wires can come into contact with each other, which also facilitates the hot-melt welding of the plastic binding wires.

[0009] Furthermore, the rear end of the rotating head is provided with a wire clearance groove, which is designed in a semi-circular shape, the same as the rear end of the rotating head. Its main function is to prevent the plastic binding wire from being pulled when the rotating head rotates.

[0010] Furthermore, the cutting device includes an electromagnet, a spring, a cutting blade, and a through hole. The electromagnet is fixedly mounted on top of the rotating head, and a cavity for accommodating the cutting blade is provided on the rotating head, with the cutting blade placed inside the cavity. A spring is provided between the electromagnet and the cutting blade. A through hole is provided on the cutting blade. In the initial state, the through hole coincides with the wire channel, and the plastic binding wire passes through the through hole. The function of the spring is to keep the cutting blade in the initial position at all times, ensuring that the through hole and the wire channel are aligned without misalignment. When it is necessary to cut the plastic binding wire, the electromagnet only needs to operate to quickly retract the cutting blade upwards.

[0011] Furthermore, the wire take-up and release device includes a mounting base plate, wire take-up and release motors, and rollers. Two wire take-up and release motors are mounted on the mounting base plate, and rollers are provided on the wire take-up and release motors. After installation, the two rollers are located on both sides of the wire channel. The rotation of the rollers realizes the release or retrieval of the plastic wire.

[0012] Furthermore, the hot melt plate has a horizontally arranged semi-circular indentation to prevent the wires on both sides from misaligning and causing the hot melt to fail during the second hot melt of the plastic binding wires.

[0013] Furthermore, it also includes a guide coil. The rear end of the partition plate is provided with a guide coil. The function of the guide coil is to guide the plastic binding wire, ensuring that the plastic binding wire can be inserted into the sliding block in a straight line while maintaining the same position.

[0014] Furthermore, both the transverse and longitudinal moving platforms consist of a moving plate, driven wheels, a driving wheel, a moving motor, a belt, a belt buckle, and a slide rail. The moving plate is slidably mounted on the slide rail. The output end of the moving motor is fixedly mounted with a driving wheel. The belt buckle is fixedly connected to the moving plate and to the belt. The moving plate is driven by the driven wheel, the driving wheel, the moving motor, and the belt. The driven wheel and the driving wheel are fixedly mounted at both ends of the base or at both ends of the moving plate on the transverse moving platform. The transverse and longitudinal moving platforms use the same components and design structure, the only difference being that one moves laterally and the other moves longitudinally.

[0015] Furthermore, the rotary motor, take-up and untake-up motor, and moving motor are all servo motors, which can precisely control the speed and angle of rotation.

[0016] The advantages of this invention are: 1. It adopts a comprehensive design of multiple mobile platforms to achieve "four-axis" linkage, which can sequentially braid multiple bundles of silk on the same fineness yarn bobbin frame; 2. During braiding, double-wire hot-melt binding is used, and the wire feeding and take-up device can feed and take back the plastic binding wire to achieve tight binding of the stranded silk; 3. The braiding of silk is automated, reducing labor costs and improving work efficiency. Attached Figure Description

[0026] The present invention will now be described in detail with reference to the accompanying drawings:

[0027] In the description of this invention, it should be noted that the orientation or positional relationship indicated by "front", "rear", etc., is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this invention is usually placed in when in use. It is only for the convenience of describing this invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, it should not be construed as a limitation of this invention.

[0028] like Figure 1-7As shown, an automatic silk weaving device includes a support frame 1, a base 2, a transverse moving platform, a longitudinal moving platform, a partition plate 3, a sliding block 4, a rotary motor 5, a rotating head 6, a hot-melt plate 7, a cutting device 8, a take-up and undo device 9, a connecting plate 10, a thread channel 11, an electric cylinder 12, and a thread spool frame 13. The support frame 1 is equipped with the base 2, which is elongated and longer than the length of the fineness measuring machine's thread spool frame. A transverse moving platform is slidably mounted on the base 2, and a longitudinal moving platform is slidably mounted on the transverse moving platform. Both the transverse and longitudinal moving platforms consist of a moving plate 15, a driven wheel 16, a driving wheel 17, a moving motor 18, a belt 19, a belt buckle 20, and a slide rail 21. The two moving platforms have the same design structure, differing only in size and direction of movement. The movable plate 15 is slidably mounted on the slide rail 21. The movable plate 15 is divided into a horizontal moving platform movable plate and a vertical moving platform movable plate. The horizontal moving platform movable plate is slidably mounted on the base 2, and the vertical moving platform movable plate is slidably mounted on the horizontal moving platform movable plate. The output end of the movable motor 18 is fixedly mounted with a drive wheel 17. The belt buckle 20 is fixedly connected to the movable plate 15 and is fixedly connected to the belt 19. The driven wheel 16 and the drive wheel 17 are fixedly mounted at both ends of the base 2 or at both ends of the movable plate 15 on the horizontal moving platform. The movable plate 15 is driven by the driven wheel 16, the drive wheel 17, the movable motor 18, and the belt 19. That is, when the movable motor 18 is working, the belt 19 will rotate under the action of the driven wheel 16 and the drive wheel 17. The rotation of the belt 19 will drive the movable plate 15 to move horizontally or vertically. The function of the lateral moving platform is to control the lateral movement of the longitudinal moving platform, and the movement length range is greater than the length of the yarn bobbin frame of the fineness machine. The function of the longitudinal moving platform is to control the partition plate 3 to be pushed forward and inserted into the silk to divide it into several small strands, which facilitates subsequent yarn weaving. After the silk is woven, the partition plate 3 is controlled to retract and move to the next bundle of silk through the lateral moving platform for yarn weaving.

[0029] A row of partition plates 3 is arranged at the front end of the longitudinal moving platform. There are typically five or six partition plates 3, depending on the number of strands the silk needs to be braided into. A sliding block 4 is slidably mounted on each partition plate 3, with corresponding slide rails and grooves between the partition plate 3 and the sliding block 4. A rotating head 6 is mounted at the front end of each sliding block 4 via a rotary motor 5. The rotary motor 5 is positioned downwards on top of the front end of the sliding block 4, primarily controlling the horizontal right-angle rotation of the rotating head 6. When two adjacent rotating heads 6 rotate relative to each other, their front ends come into contact. The front end of each partition plate 3 is pointed, and the front end of the rotating head 6 is located behind the pointed end, ensuring that the rotating head 6 does not interfere with the partition plate's ability to separate the silk fibers.

[0030] The rear end of the sliding block 4 on the partition plate 3 is fixedly mounted on the connecting plate 10, and the connecting plate 10 connects the sliding blocks 4 on the partition plate 3 into a whole. The electric cylinder 12 is fixedly mounted on the longitudinal moving platform, specifically on the moving plate of the longitudinal moving platform. The front end of the electric cylinder 12 is fixedly connected to the connecting plate 10. By controlling the forward and backward movement of the sliding block 4 through the electric cylinder 12, the rotating head 6 can be controlled to perform heat fusion welding of plastic binding wire in front of or behind the silk. A row of wire spool racks 13 is provided on the longitudinal moving platform. The wire spool racks 13 are used to place the plastic binding wire 23, and each sliding block 4 is equipped with a wire spool rack 13.

[0031] The wire channel 11 runs through the connecting plate 10, sliding block 4, rotating head 6, and hot melt plate 7. Specifically, the end of the plastic binding wire 23 on the wire tube frame 13 first passes through the connecting plate 10, then sequentially through the sliding block 4, rotating head 6, and hot melt plate 7, finally appearing at the front end of the rotating head 6. When two adjacent rotating heads 6 rotate relative to each other, their front ends contact each other, and the ends of the plastic binding wire 23 on both sides contact each other. After contact, when the hot melt plate 7 operates, the ends of the two sides fuse together. To prevent the rotating head 6 from pulling or clamping the plastic binding wire 23 during rotation, a wire clearance groove 22 is provided at the rear end of the rotating head 6. The wire clearance groove 22 is semi-circular, and its height is the same as the height of the wire channel 11. The diameter of the wire channel 11 is 1.2 to 2.0 times larger than the diameter of the plastic binding wire 23, facilitating the rapid passage of the plastic binding wire 23. The diameter of the wire channel 11 on the hot melt plate 7 can be larger, while other areas can have smaller diameters. The plastic cable used should not be too soft; if it is too soft, it will be difficult to reel in and unreel. It should be of moderate softness so that it is easy to reel in and unreel.

[0032] The rotating head 6 has a flat front end and a semi-cylindrical rear end. A hot-melt plate 7 is provided on the front end face of the rotating head 6. The hot-melt plate 7 is located at the center of the front end face of the rotating head 6. A semi-circular indentation 71 is horizontally provided on the hot-melt plate 7. The function of the semi-circular indentation 71 is to allow the plastic binding wire to enter the semi-circular indentation 71 when taking in the plastic binding wire, facilitating wire taking in and subsequent hot melting. A chamfered notch is provided at the front end of the rotating head 6 to facilitate the plastic binding wire falling back to the middle position. The rotating head 6 is equipped with a cutting device 8 and a wire take-up and undoing device 9. The cutting device 8 is located in front of the wire take-up and undoing device 9. The cutting device 8 is mainly used to cut the plastic binding wire 23 passing through the rotating head 6. Figure 8The cutting device 8 shown includes an electromagnet 81, a spring 82, a cutting blade 83, and a through hole 84. The electromagnet 81 is fixedly mounted on top of the rotating head 6. The rotating head 6 has a cavity for accommodating the cutting blade 83; the upper part of the cavity is cylindrical, and the lower part is a flat strip. The cutting blade 83 is placed inside the cavity and consists of a blade holder made of iron and a steel blade. After installation, the blade fits perfectly into the lower flat strip of the cavity. The spring 82 is positioned between the electromagnet 81 and the cutting blade 83. The cutting blade 83 has a through hole 84, which initially coincides with the wire channel 11. The spring 82 keeps the cutting blade in a fixed position, ensuring the through hole 84 aligns with the wire channel 11, thus preventing interference with the passage of the plastic binding wire. When cutting the plastic binding wire, simply activate the electromagnet 81 to lift and attract the cutting blade 83.

[0033] like Figure 9 As shown, the wire take-up and release device 9 includes a mounting base plate 91, wire take-up and release motors 92, and rollers 93. Two wire take-up and release motors 92 are mounted on the mounting base plate 91, and rollers 93 are provided on the wire take-up and release motors 92. After installation, the two rollers 93 are located on both sides of the wire channel 11. After installation, the two rollers 93 will clamp the plastic binding wire 23, and the take-up and release of the plastic binding wire 23 is realized by the rotation of the rollers 93.

[0034] In order to allow the plastic binding wire 23 to smoothly enter the wire channel 11 from the wire spool 13, a guide coil 14 is also provided. A guide coil 14 is provided at the rear end of the partition plate 3.

[0035] In addition to the aforementioned technical features, the technical solution of this invention also includes a controller. The controller can control the coordination between the transverse moving platform, the longitudinal moving platform, the rotary motor 5, the hot melt plate 7, the cutting device 8, the take-up and undo device 9, and the electric cylinder 12 according to a set program. The rotary motor 5, the take-up and undo motor 92, and the moving motor 18 are servo motors. To better control the take-up and undo, a sensor should also be installed inside the rotating head 6. The sensor is used to monitor the tightness or tension of the plastic binding wire, and the tightness of the binding during the take-up and bundling of the silk is determined by the tightness or tension of the plastic binding wire.

[0036] The operating principle of this invention is as follows: The yarn bobbin frame of the yarn finening machine is moved to the front of the automatic yarn braiding device. Before braiding, the relative positions of the two components and the width and spacing of the silk threads on the yarn bobbin frame need to be determined to facilitate the control of the horizontal and vertical moving platforms. Once the positions of the yarn bobbin frame and the automatic yarn braiding device are fixed, the vertical moving platform is controlled to push out the separator plate 3 to separate the silk threads. After separation, the electric cylinder 12 pushes out the rotating head 6, positioning it behind the silk threads. Then, the rotating motor 5 controls the rotating head 6 to rotate at a right angle (initially, the rotating head 6 is parallel to the separator plate 3), causing the end faces of adjacent rotating heads 6 to contact. After the end faces of the rotating heads 6 contact, the take-up and release device 9 releases the plastic binding wire 23 until the ends of the plastic binding wire 23 on the end faces of the two rotating heads 6 contact. Then, the wire ends are heated and fused together when the heat-melting plate 7 is heated. After the thread ends are fused, the rotating head 6 is controlled to rotate at a right angle and parallel to the separator plate 3; then the electric cylinder 12 retracts the rotating head 6 so that it is in front of the silk; then the rotating head 6 is controlled to rotate so that the end faces of adjacent rotating heads 6 contact (before this operation, the take-up and release devices are in the release state); then the take-up and release device 9 controls the take-up to tightly bind the separated silk; then the heat-melting plate 7 is heated to fuse the bodies of the plastic binding wires 23 on both sides; finally, the cutting device 8 is controlled to cut the plastic binding wires 23 and return the rotating head 6 to its initial position to complete the separation and binding of the silk. Because the same bundle of silk cannot be bound at once during the weaving process, it needs to be bound in two batches. For example, a bundle of silk is bound into 4 small bundles, and the rotating heads are numbered 1-5. During operation, rotating heads 1-4 are used to bind the first and third bundles of silk, and then rotating heads 2-5 are used to bind the second and fourth bundles of silk. After the silk is bundled, the longitudinal moving platform and the dividing plate are retracted, and then the silk is moved to the next bundle of silk for weaving via the transverse moving platform.

[0037] Although the specific embodiments of the present invention have been described and illustrated in detail above, it should be noted that various changes and modifications can be made to the above embodiments without departing from the spirit of the present invention and the scope set forth in the appended claims.
