Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to an automatic carpet weaving machine of the carpet cutting type. Background Technology

[0002] Carpets are made from natural fibers such as cotton, linen, wool, silk, and grass yarn, or chemically synthesized fibers, through hand or machine processes of weaving, tufting, or spinning. Among these, cut-down carpets, due to their complex weaving process, especially the use of figure-eight knots to bind the warp threads, generally still rely on hand weaving. A ten-foot carpet typically requires four skilled workers about a year to complete, and the finished product often suffers from uneven pile, which not only hinders the subsequent trimming process but also wastes precious raw materials.

[0003] To address the aforementioned issues, the applicant has researched and designed an automatic carpet weaving machine that processes carpet pattern data and automatically implements each weaving process of carpet cutting, replacing manual weaving, reducing labor intensity, and improving work efficiency. Summary of the Invention

[0004] The technical problem this invention aims to solve is to overcome the defects of manual operation mentioned above, and to provide a design scheme for an automatic carpet weaving machine for cut carpet types. The control system, with a single-chip microcomputer as its core, processes carpet design drawings and automatically controls the mechanical equipment to realize each weaving process of the cut carpet, including binding the front and back warp threads with figure-eight knots and the edge-wrapping operations on the left and right sides of the carpet. Input methods include inputting the design data via a microcomputer through a network, USB flash drive, or manually.

[0005] This invention focuses on the design of the front and rear warp (thread) transformation of the mechanical parts, the formation of the figure-eight knot, and the related weaving process. Taking a 10-foot width, 160 warp threads per foot, and 6 pattern colors as an example, the design is performed by 6 thread cutters: thread cutter A, thread cutter B, thread cutter C, thread cutter D, thread cutter E, and thread cutter F. (See...) Figure 15 As shown. However, it applies to all figure-eight knot carpet cutting processes. Increasing the number of I / Os in the system can increase the number of pattern dyeing operations. Therefore, it is recommended to use a 32-bit microcontroller.

[0054] Appendix: Proximity electromagnetic switch designations, names, and functions. Detailed Implementation

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all embodiments. For example, 80-type and 120-type knitted blankets, and 160-type blankets with finer yarn, more difficult manufacturing process, and higher price, the components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed with various different knitted blanket models.

[0056] In the description of the embodiments of this invention, the application term "proximity electromagnetic switch XX" is used unless otherwise specified as inductive. All are connected to the input ports of the control chips not listed. In addition to determining the object being measured, each proximity electromagnetic switch controls the level of other output ports through system programming instructions. The output ports are implemented in conjunction with electrical circuits through common electronic and electrical devices, such as field-effect transistors and time relays.

[0057] Combined with appendix Figure 1The overall support frame includes left front support column 1, left front support column 2-1, right front support column 1-1, right front support column 2-2, and two symmetrically arranged rear support columns 2. Between right front support column 1-1 and right front support column 2-2, beams 1-3, 1-4, 1-5, 1-6, and 1-7, cut from I-beams, are welded together. Between left front support column 1 and left front support column 2-1, beams 6-8, 1-9, 1-10, 1-11, and 1-12, cut from I-beams, are welded together. The straight groove bar 4 is bolted to beams 7-9 and 2-4 at both ends. The straight groove bar 4 has 160 grooves per foot. Multiple warp yarn storage spools 34 with damping springs 38 are located on the rear side of the straight groove bar 4. (See...) Figure 23 As shown, each warp thread, after descending from the warp thread storage 34, flows down along the straight grooves on the straight groove bar 4 to the bottom bar 3. The bottom bar 3 is connected to the crossbeams 1-12 and 1-7 by two bearings 21. Two limiting circular plates 5 are symmetrically arranged on the bottom bar 3 to prevent the fabric from shifting left and right. Behind the bottom bar 3 is a winding storage shaft 35 with a winding brake electromagnet 36, driven by a motor 37, to wind the woven carpet. Figure 24As shown, it is controlled by a proximity electromagnetic switch 26-1 installed at the lower stop point of the support 8. Below the straight bar 4, odd-numbered kites 6 and even-numbered kites 6-1 with identical structures are sequentially installed parallel above the support 8. Each kite includes a frame and stainless steel strips 6-2. The frame is rectangular, and multiple stainless steel strips 6-2 are arranged in an array along its length within the frame. A gap is provided between adjacent stainless steel strips 6-2, and round holes 6-3 are provided on the stainless steel strips 6-2. Bearings 21-2 and 21-3 are located at the center of each end of each kite. Four track plates 7, which cooperate with bearings 21-2 and 21-3, are horizontally welded to the inner sides of the left front support 1, left front support 2-1, right front support 1-1, and right front support 2-2, respectively. Below the even-numbered kite 6-1, there is a base 8. On the inner long side of the base 8, there is an upper pressure plate 9 connected by two hinges 9-1. Below the upper pressure plate 9, there is a matching lower base plate 10. Above the lower base plate 10, there are three needle plates, each with a needle groove. According to the inclination direction of the needle groove, they are divided into left-leaning needle plate 11, right-leaning needle plate 13, and straight groove needle plate 12. The needle grooves hold hooks. Two pairs of shuttle magazines are located on the left and right sides below the base 8 at the shuttle supply position or the shuttle receiving position. The arrow shaft shuttle throwing device on the outside of the right front support column 1-1 and right front support column 2-2 is set in conjunction with the shuttle magazines at the shuttle receiving position or the shuttle supply position. The left and right pairs of shuttle magazines are welded to the two sides of the connecting shaft 14-8 through brackets. The bearings at both ends of the connecting shaft 14-8 are connected to the upper side of the crossbeam 4 and crossbeam 9. Between the left front support 2-1 and the right front support 2-2 and the two symmetrically arranged rear supports 2, a crank-connecting rod mechanism is provided, including: a drive shaft 16 located at the lower part between the two rear supports 2; a driven gear 16-1 coaxially mounted on the drive shaft 16, meshing with a drive gear 17-1 coaxially connected to an asynchronous motor 17; two bearings 21-1 connecting the two rear supports 2 at both ends of the drive shaft 16; and two cranks 18 bearings connecting the other ends of the two cranks 18 to one end of two connecting rods 19; and one of the three connecting holes in the middle of the rocker arm 20; one end of the rocker arm 20 connected to the two rear supports 1 via two bearings; and the other end of the rocker arm 20 fixedly connected to the two ends of the rocker arm 8 extending between the left front support 1-1, the left front support 2-1, the right front support 1-1, and the right front support 2-2 via bolts.

[0058] The warp wire storage shaft 34 is formed by a square steel bar passing through the center of multiple plastic grooved wheels 39, the hollow of a damping spring 38, and the square center of a plastic circular plate 40. (See...) Figure 23 As shown, each plastic grooved wheel 39 stores warp threads, and each warp thread storage spool 34 is installed in different positions (up, down, front, and back) and both ends are fixed to the back support frame 25-2, so that they do not interfere with each other in providing warp threads to the straight girder 4.

[0059] In practice, the odd-numbered zither 6 and the even-numbered zither 6-1 used for cutting the carpet width of ten feet are shown in the following figures. Figure 2 As shown in Figure A, the structure consists of 800 stainless steel strips 6-3 with a 1.2 mm center hole and 2 stainless steel strips 6-2 with a 1.5 mm center hole, along with a frame 6-1. The stainless steel strips 6-2 are 2 mm thick, 300 mm long, and 2.5 mm wide, arranged in a single plane with a center-to-center distance of 3.81 mm. The leftmost and rightmost stainless steel strips 6-2 have 1.5 mm diameter holes 6-3, which can be individually detached. When weaving carpet patterns, they are separately fixed to the front support bracket 32 ​​and the back support bracket 25-2, maintaining the front and rear warp positions so that the shuttle box passes between the front and rear warps. The long sides of the two kites are made of 30×30 mm angle iron, which is processed into 30×25 mm angle iron with holes at both ends. The ends of stainless steel strips 6-2 are arranged on the 25 mm surface of the angle iron. The pressure strip 8-4 is made of 20×20 mm angle iron with holes at both ends. The cross braces 8-5 at both ends of the kites are made of 30×30 mm angle iron with holes at both ends. The pressure strip 8-4 presses the stainless steel strips 6-2 into the two long sides of the frame 6-1. The cross braces 8-5 at both ends of the kites press the ends of the pressure strip 8-4 onto the two long sides of the frame 6-1 respectively. The bearings 21-2 and 21-3 in the cross braces 8-5 at both ends are supported on the two track plates 7.

[0060] In the specific implementation of the odd-numbered kite 6, odd-numbered meridians 24-14 pass through the circular holes 6-3 respectively, and even-numbered meridians 24-15 pass through the gaps between adjacent stainless steel strips 6-2 respectively. Similarly, in the specific implementation of the even-numbered kite 6-1, even-numbered meridians 24-15 pass through the circular holes 6-3 respectively, and odd-numbered meridians 24-14 pass through the gaps between adjacent stainless steel strips 6-2 respectively. Figure 2 As shown in Figure B, the device for driving the odd-numbered kite 6 and the even-numbered kite 6-1 to move in opposite directions includes: a traction electromagnet 6-4 fixed to the left front left support 2-1 of the even-numbered kite 6-1 and a traction electromagnet 6-5 fixed to the right front right support 1-2 of the odd-numbered kite 6; a lever 6-10 behind the even-numbered kite 6-1 and a lever 6-11 behind the odd-numbered kite 6; a central fulcrum shaft, which is connected and fixed to the back support frame 25-2 respectively; two fulcrums that are slidably and rotatably connected to the fulcrum shaft respectively; and street rails 6-6 and 6-7. The left end of lever 6-10 and the right end of lever 6-11 are connected by pull rope 1 6-8 and pull rope 2 6-9 respectively. Grooved wheel 1 6-12 and grooved wheel 2 6-13 are vertically installed on the front support 32 in front of the two kites, with the upper edge aligned with the odd-numbered kite 6 and the lower edge aligned with the even-numbered kite 6-1. The other ends of lever 1 6-10 and lever 2 6-11 are connected to the two rear ends of the two kites by pull ropes. The two front ends of the two kites are connected by pull ropes that pass around grooved wheel 1 6-12 and grooved wheel 2 6-13 respectively.

[0061] Working process: Traction electromagnet 6-4 and traction electromagnet 6-5 work alternately. 1. In the reset state, the two kite planes are basically aligned vertically, and the two traction electromagnets are not energized; 2. Odd kite 6-4 is in front, and even kite 6-1 is staggered behind; 3. Odd kite 6-4 is behind, and even kite 6-1 is staggered in front. After traction electromagnet 6-4 is energized, it drives lever 6-10 to rotate through pull rope 6-8. Lever 6-10 drives even kite 6-1 to move backward through the pull rope. The two pull ropes at the two ends in front of even kite 6-1 are redirected by grooved wheel 6-12 and grooved wheel 6-13, pulling odd kite 6-4 forward, realizing that odd kite 6 and even kite 6-1 move in opposite directions. When traction electromagnet 26-5 is energized, it drives lever 26-11 to rotate via pull rope 26-9. Lever 26-11 then moves odd-numbered warp 6 backward via pull rope. The two pull ropes at the front ends of odd-numbered warp 6, after being redirected by grooved wheel 16-12 and grooved wheel 26-13, pull even-numbered warp 6-1 forward. This completes the position change of the front and rear warp lines, hereinafter referred to as front and rear warp change. When either of the two traction electromagnets is energized and then de-energized, the damping spring 38 on the warp wire storage shaft 34 exerts a force on the warp width, and the combined action of the internal springs of traction electromagnet 16-4 and traction electromagnet 26-5 will pull both lines back to their original positions.

[0062] The 8th component includes a long side, a cross brace 8-2, an arc-shaped stainless steel sheet 8-3, and a pressure strip 8-1. (See attached image) Figure 3 As shown in Figure C, the two long sides are arranged in parallel front to back, and multiple arc-shaped stainless steel sheets 8-3 are arranged in an array between the two long sides. The two sides of the arc-shaped stainless steel sheets 8-3 are arc-shaped. Figure 3 As shown in Figure B, two flat ends are symmetrically arranged at both ends, and a gap is provided between two adjacent arc-shaped stainless steel sheets 8-3. In specific implementation, the sheet 8 is composed of 803 arc-shaped stainless steel sheets 8-3, each 10 mm wide, 140 mm long, and 1 mm thick, arranged vertically, with a center distance of 3.81 mm. All warp threads pass sequentially through the gap between the two arc-shaped stainless steel sheets 8-3. The four sides are welded from 30×30 mm angle iron. The two ends of the arc-shaped stainless steel sheets 8-3 are fixed to the two long sides of the frame by screws with two identical pressure strips 8-1. The pressure strips 8-1 are made of 20×20 mm cast iron with slots, such as... Figure 3As shown in Figure A, 803 steel grooves 30-1, each 1.2 mm wide and 10 mm deep, are machined on one side. The ends of the arc-shaped stainless steel sheet 8-3 are inside the steel grooves 30-1 and pressed against the two long sides of the frame. The arc-shaped stainless steel sheet 8-3 is installed with a downward curve. When the woven carpet 8 descends to the lower stop point, the inner edge of the lower front edge of the woven carpet 8 is close to the warp thread to prevent the outer edge from hitting the needle plate. When the woven carpet 8 reaches the upper stop point, the proximity electromagnetic switch 26 installed at the upper stop point sends a positioning signal to the system, and the asynchronous motor 17 stops. Due to inertia, the upper and lower mounting positions of this proximity electromagnetic switch 26 can be finely adjusted to adjust the amount of time the asynchronous motor 17 stops earlier. Because the driving gear 17-1 is small and the driven gear 16-1 is large, it acts as a brake. The weight of the woven carpet 8 is insufficient to drive the driving wheel to turn incorrectly. Each time the woven carpet 8 descends, it compacts the yarn segments 9-7 and the thick and thin weft threads, providing a propulsive effect on the woven carpet. The brake solenoid 36 on the winding storage shaft 35 is controlled by the proximity solenoid switch 26-1 installed at the lower dead center of the shaft 8. When the shaft 8 reaches the lower dead center, the winding motor 37 of the winding storage shaft 35 starts, the brake solenoid 36 on the winding storage shaft 35 momentarily releases and then brakes, and the winding motor 37 is de-energized. Figure 24 As shown. The rocker arm 20 is made of 25×25 mm angle iron with holes drilled in it. One of the three holes connected to the bearing of the connecting rod 19 is selected to adjust the lower dead center height of the rod 8.

[0063] The upper pressure plate 9 is long and narrow, made of a steel plate 20 mm wide and 3 mm thick, and is installed vertically on the long side of the carpet 8, along with the carpet's pile edge, such as... Figure 4As shown, two 44×15 mm hinges 9-1 (also known as hinges) with internal springs are used for connection and fixation. To prevent the hinges 9-1 from folding inwards by mistake, there is an adjustable set screw 9-2 at each end of the upper pressure plate 9, which presses against the outer edge of the horizontal frame of the 8. The lower base plate 10, which cooperates with the upper pressure plate, is rectangular and made of a steel plate 20 mm wide and 3 mm thick. At the center of both ends, there is a rotating shaft wrapped by a rotating spring 9-4, which is slidably connected to the middle of the support rod 10-1. The rotating spring 9-4 controls the upper edge of the lower base plate 10 to be inward and the lower edge to be outward. Limiting rods 10-2 are set on both sides below and welded to the inner side of the lower end of the support rod 10-1. The function of the limiting rod 10-2 is to position the upper edge when the rotating spring 9-4 rebounds. The upper end of the support rod 10-1 presses on the limiting plate 9-3. The lower outer bearing of the support rod 10-1 is connected to one end of the spring shaft 9-6. The other ends of the two spring shafts 9-6 are welded to the crossbeam 3 1-5 and crossbeam 8 1-10 respectively. The spring shaft 9-6 controls the support rod 10-1 to be in a vertical state. Two limiting plates 9-3 are threadedly connected to the left front support column 1 and the right front support column 1-1, respectively. The limiting plates 9-3 are made of Z-shaped bent round steel with one end threaded. The threads are inserted into the adjusting nut for fixation. They cooperate with the top screw 9-2 to adjust the gripping point and outward pulling distance of the upper pressure plate 9 and the lower base plate 10 to the number line segment 9-7. When the spring shaft 9-6 of the lower base plate 10 rebounds, it positions the support rod 10-1. When the number line segment 9-7 is compacted by the downward movement of the number 8, the upper pressure plate 9 cooperates with the base plate 10 in advance, clamping the two ends of the number line segment 9-7 which is shaped like an "8" around the warp. The support rod 10-1 is subjected to downward pressure, overcomes the spring resistance on the spring shaft 9-6, and moves away from the limiting plate 9-3. The lower base plate 10 is subjected to downward pressure, overcomes the resistance of the rotating spring 9-4, moves away from the limiting rod 10-2, and pulls the number line segment 9-7 outward. To prevent slippage of line segment 9-7, soft rubber is applied to the mating surfaces of the upper pressure plate 9 and the lower base plate 10 to improve gripping force. When line segment 8 moves away from the lower stop point, the upper pressure plate 9 disengages from line segment 9, and the lower base plate 10 springs back to its original position.

[0064] Shuttle box Figure 18 As shown in B, it includes two identical shuttle boxes, which are quadrangular cylindrical in shape and made of ABS plastic. They are used to hold coarse weft tassels and fine weft tassels, respectively. Each box has a groove 14-2 on its right end, and an iron plate 14-3 is inlaid within the groove 14-2. The iron plate 14-3 is shown in [the diagram]. Figure 18 As shown in Figure C, a guide hole 14-4 is provided in the middle, which is matched with the spike 15-5. A thread outlet hole 14-5 is provided in the center of the bottom of the shuttle box. The weft tassel is placed inside the shuttle box, and the weft thread passes through the tassel wall and is led out of the shuttle box through the thread outlet hole 14-5. In other words, the tassel is supplied with thread by a vacuum method.

[0065] The arrow shaft shuttle-throwing device is installed on the outside of the right front support 1-1 and the right front support 2-2, and corresponds to the right shuttle magazine 14-1 in the shuttle-reading position or the shuttle-supplying position. Figure 1As shown, the left shuttle magazine 14 and the right shuttle magazine 14-1 correspond to each other via connecting shaft 14-8, and the left shuttle magazine 14-9 and the right shuttle magazine 14-10 correspond to each other via connecting shaft 14-8. The two ends of connecting shaft 14-8 are respectively connected to the crossbeams 1-6 and 1-11. Figure 18 As shown in Figure F, the arrow shaft shuttle-throwing device includes an arrow shaft 15-1, an arrow shaft rack 15-6, an arrow shaft guide cylinder 15-8, a shuttle suction device, an arrow shaft motor 15-7, and a gear 15. (See Figure F for details.) Figure 18 As shown in Figure E, the shuttle includes a plastic nut 15-2, a coil 15-3, an arrow shaft rail 15-4, and a spike 15-5. The plastic nut 15-2 and the coil 15-3 are cast as one piece. A plastic screw is fixed to the left end of the arrow shaft 15-1, which is threadedly connected to the plastic nut 15-2. The arrow shaft rail 15-4 is located at the center of the coil 15-3. The head of the arrow shaft rail 15-4 has a spike 15-5. An arrow shaft rack 15-6 is welded to the lower part of the arrow shaft 15-1, extending out of the opening of the arrow shaft guide tube 15-8 and engaging with the arrow shaft. The gear 15 is coaxially connected to the motor 15-7. The arrow shaft guide tube 15-8 is formed by opening a steel pipe with an inner diameter larger than the outer diameter of the arrow shaft 15-1. Both ends are fixed to the arrow shaft support (not shown) extending to the right from the right front support column 1-1 and the right front support column 2-2. The arrow shaft performs shuttle throwing operations between the right front support column 1-1 and the right front support column 2-2. The arrow shaft 15-1 is slidably connected inside the arrow shaft guide tube 15-8. The start and stop of the arrow shaft motor 15-7 are controlled by the Hall proximity electromagnetic switches on the four shuttle magazines through the system. In specific implementation, the shuttle coil 15-3 is wound around the arrow shaft rail 15-4. The magnetic field generated by the energized coil 15-3 attracts the iron plate 14-3 on the shuttle box. Guided and positioned by the spike 15-5, the shuttle box is stabilized on the shuttle.

[0066] The shuttle magazine's shuttle position or shuttle supply position is located below the 8th frame, and the shuttle box is stored in the magazine. Left shuttle magazine 14 and left shuttle magazine 14-9 are identical in appearance and are fixed to both ends of the left shuttle magazine frame with screws. Right shuttle magazines 14-1 and right shuttle magazine 14-10 are identical in appearance and are fixed to both ends of the right shuttle magazine frame with screws. See [link / details]. Figure 18 F, the left shuttle compartment 14 and the right shuttle compartment 14-1 alternately store the coarse weft shuttle box, and the left shuttle compartment 14-9 and the right shuttle compartment 14-10 alternately store the fine weft shuttle box. The entrances of the left shuttle compartment 14 and the left shuttle compartment 14-9 are shaped like trumpets 31, see... Figure 18As shown in Figure A, to prevent deviation in shuttle insertion due to the shaking of the arrow shaft 15-1, four shuttle holders are equipped with spring balls 30-2, 30-3, 30-4, and 30-5 at their bottoms, corresponding to the wire outlet holes 14-5 at the bottom of the shuttle box, locking the inserted shuttle box and preventing it from slipping. At the entrances of the four shuttle holders, proximity electromagnetic switch brackets are equipped with Hall effect proximity electromagnetic switches 26-2, 26-3, 26-13, and 26-14, respectively, to detect the arrival of the energized coil 15-3 on the shuttle picker. The proximity electromagnetic switch 26-4, installed below the center of the crossbeam 1-6, identifies the vertical position information of the right shuttle magazine, determines that all shuttle magazines have reached the supply or receiving position, and controls the micro motor 14-6 to stop at the receiving or supply position. The left shuttle magazine 14 and right shuttle magazine 14-1, or left shuttle magazine 14-9 and right shuttle magazine 14-10, synchronously rotate upwards 90° and stop, waiting for the shuttle to be received or supplied. Figure 18 As shown in F, the right shuttle magazine 14-1 connecting plate is sensed by the proximity electromagnetic switch 126-12 installed on the right front support column 1-1, which controls the micro motor 14-6 to stop rotating, so that the two pairs of shuttle magazines are idle in a longitudinal horizontal state, making room for the downward movement of the 8.

[0067] The first step in processing serial number 9-5 is wax pool 27, see Figure 7 As shown, the wax pool 27 includes a housing 27-1, and three heating elements 27-2, 27-3, and 27-4 disposed within the housing 27-1. A wire clamping bar 27-5 is horizontally disposed within the housing 27-1, and a wire outlet hole 27-6 is disposed on its front side. A thermocouple 27-7 is disposed on one side of the housing 27-1. Wax liquid at 70℃~80℃ is placed inside the housing 27-1. The temperature control system for the wax liquid includes a thermocouple and an external temperature controller. The three heating elements in the wax pool 27 heat the wax liquid. The wire outlet hole 27-6 installed on the wall of the wax pool 27 should be smooth and clean, conical in shape, larger inside and smaller outside, with a large diameter of 3 mm, a small diameter of 1.8 mm, and a length of 5 mm. It is made of copper and its main function is to limit the diameter of the 9-5 wire and filter out excess wax liquid. In practice, after all the 9-5 threads come off the spool, they first pass under the pressure bar 27-5 in the wax liquid. After being immersed in heated wax, they reach the exit hole 27-6 and exit the wax pool 27. After natural cooling, they become firm and straight, increasing the slipperiness of the 9-5 threads and laying the foundation for subsequent processes. After the entire carpet weaving is completed, there is a carpet washing process where the wax is removed using warm water above 60℃.

[0068] The second step in processing wire 9-5 is that wires of various colors 9-5 enter their respective wire cutters 25 and are cut into wire segments 9-7. The wire cutter 25 includes a support 25-1, an infrared LED 25-3, a photodiode 22-4, a control circuit board housing 22-15, a jog button 25-12, a cutting blade traction electromagnet 25-5, a crossbar 25-7, a blade head 25-8, a blade head base plate 25-19, a return spring 25-10, a blade 25-9, a blade holder 25-17, a dovetail blade 25-4, and a rubber ball housing 28-1. (See...) Figure 8 As shown in Figure A, the infrared LED 25-3 is physically located within the elongated plate 28-11 described below, but it is an external component in the control circuit. (See Figure A for details.) Figure 21 As shown, the control circuit board 25-11 is located inside the control circuit board housing 22-15. The control circuit board housing 25-15 is a plastic square box, which is suspended by screws below the upper horizontal part of the cutter head base plate 25-19. A jog button 25-12 is provided on the right end of the plastic square box. The rubber ball housing 28-1 contains rubber balls 28, rubber balls 28-4, a Y-shaped bracket 20-1, a retaining ring 20-3, a toothed conveyor belt 20-2, a toothed conveyor belt drive wheel 28-5, a toothed conveyor belt driven wheel 28-6, and a DC motor 25-13. The rubber balls 28 are a pair of rubber spheres that are pressed against each other outside the two vertical sides of the toothed conveyor belt 20-2. Figure 9 As shown in AC, the diameter is 22 mm. The rubber sphere has a copper sphere inside and is covered with rubber. The two long sides of the Y-shaped bracket 20-1 serve as support shafts, passing through the center of the sphere and the retaining ring 20-3. The retaining ring 20-3 is located in the support shaft groove below the sphere, limiting the sphere's position. The included angle between the two shafts is 50°. The bottom feet of the two Y-shaped brackets 20-1 pass through the two holes ab in the middle of the bottom shell and are fixed by nuts. The upper ends extend from both sides of the outer shell 28-1 of the rubber sphere, and a removable top cover 28-2 limits its position. See Figure 9 As shown in ACD, the upper horizontal edge of the cross-section of the toothed conveyor belt 20-2 is made into a rack, which meshes with the toothed conveyor belt drive pulley 28-5 and the toothed conveyor belt driven pulley 28-6. The two vertical edges are made of soft rubber, and the lower arc-shaped groove 22 clamps the wire 9-5. Figure 9 As shown in AB, the toothed conveyor belt 20-2 is driven by a DC motor 25-13. The toothed conveyor belt 20-2 rotates the rubber balls 28-4, and the wire 9-5 enters the material holding groove 22 of the toothed conveyor belt 20-2 through the inlet hole 28-3. The guide plate 27-8 appears to be a 10×10 mm angle iron, with one end welded to the upper edge of the outlet hole inside the rubber ball shell 28-1, and the other end shaped like an arrow. Figure 14As shown in Figure B, the two vertical edges of the clamping wire 9-5 are extended towards the toothed conveyor belt 20-2, forcing the two vertical edges to fold outwards to both sides at the turning point of the driven wheel, releasing the clamped wire 9-5. The wire 9-5 exits from the round hole under the inner corner of the guide plate 27-8 and connects to the rubber ball shell 28-1, between the blade 25-9 and the dovetail blade 25-4. Enter into the feeding hole 22-2 on the feeding plate 22-1. See Figure 8 As shown. The Y-shaped bracket 20-1 and the toothed conveyor belt 20-2 have an angle of less than 90° in their direction of travel. Figure 9 C. During the rotation of the spheres, there is a leftward and upward thrust on the toothed conveyor belt 20-2. The wire 9-5 is securely held in the material-holding groove 22 of the toothed conveyor belt 20-2, preventing the wire 9-5 from falling between or below the two spheres. However, the angle should not be too small; otherwise, it will increase the load on the DC motor 25-13, and the two sets of mating balls will lose rotation. A DC motor 25-13 is installed on one side of the mating ball shell 28-1, coaxially fixed to the side of the mating ball shell 28-1 with the toothed conveyor belt drive wheel 28-5. The mating ball shell 28-1 is welded from steel plates, and the M8 threaded holes at the four corners of the bottom are bolted to the back support frame 25-2. See [link / details]. Figure 9 As shown in D, Figure 14 In the middle, the four M8 threaded holes on the left side of the rubber ball shell 28-1 are fixed to the lower right side of the cutter head base plate 25-19 by four screws through the fixing holes 25-18 on the four cutter head cover plates 25-14.

[0069] exist Figure 8 In section A, at the lower end of the vertical rod of bracket 25-1, a photodiode 22-4 that matches the light-transmitting hole 22-3 is glued with AB adhesive. Bracket 25-1 is made of 10 mm diameter steel pipe, and its upper right end is threaded into the M10 hole of the cutter head base plate 25-19. Figure 14As shown in Figure A, the cutter head base plate 25-19 is welded from steel plate. The cutter head 25-8 is a one-piece cross-shaped piece made of stamped steel plate. The cutter head crossbar 25-7 is located at the top of the crossbar and is cut from a round steel bar, welded to the cutter head 25-8 as a whole. The cutter head 25-8 is located in the cutter head groove 25-16. On the right side of the upper vertical part of the cutter head base plate 25-19, the cutter traction electromagnet 25-5 is fixed by screws. The street iron 25-6 is located inside the cutter traction electromagnet 25-5, and its lower end rests on the cutter head crossbar 25-7. The round hole at the lower end of the cutter head 25-8 is fixed by screws through the blade 25-9 and the blade holder 25-17, and then fixed by nuts. The dovetail blade 25-4 is fixed to the cutter head base plate 25-19 below the blade 25-9 by screws through the metal pad 25-20. The metal pad 25-20 is a cuboid. The crossbar 25-7 of the cutter head is impacted by the grounding iron 25-6 inside the energized cutter traction electromagnet 25-5. The cutter head 25-8 slides downward within the cutter head groove 25-16, overcoming the resistance of the return spring 25-10. The blade 25-9 engages with the dovetail blade 25-4 to cut the wire 9-5. After the cutter traction electromagnet 25-5 is de-energized, the return spring 25-10 returns the cutter head 25-8 to its original position. The lower end of the return spring 25-10, which surrounds the crossbar under the cutter head 25-8, is supported at the bottom of the cutter head groove 25-16. The side of the return spring 25-10 is exposed through the window of the cutter head cover plate 25-14, and the other side of the return spring 25-10 is exposed through the window on the left side of the rubber ball housing 28-1 (see...). Figure 14 In B), it is exposed inside the outer shell 28-1 of the rubber ball. In a specific implementation, the blade 25-9 and the dovetail blade 25-4 are made of alloy steel.

[0070] On each wire cutter 25, the light signal emitted by the installed infrared LED 25-3 passes through the light-transmitting hole 22-3 on the feed plate 22-1 to reach the photodiode 22-4. The photodiode 22-4 receives the light signal and transmits it to the system board and control circuit board 25-11. The cutting blade traction electromagnet 25-5 is controlled by the light signal and the electrical signal sent from the microcontroller's "I / O" port on the system board. Figure 22 Pins 9-14 of the CT11 power strip are connected to pin 3 of one of the following: an optocoupler, or pin 3 of power strip P1, P2, P3, P4, P5, or P6. Figure 21 The base of Q1 and Q2 are both indispensable. When the two conditions are met, the control circuit board 25-11 on the wire cutter 25 supplies power to the DC motor 25-13. (See...) Figure 8 Electrical principles Figure 21As shown, the rubber ball 28-4, rubber ball 28, and toothed conveyor belt 20-2 pull the wire 9-5 into the feeding hole 22-2. When the wire 9-5 blocks the light-transmitting hole 22-3 at the tail of the feeding hole 22-2, the light path is cut off, the photodiode 22-4 is in a high-resistance state, Q2 and Q3 are cut off, and the DC motor 25-13 is de-energized. Figure 21 The electrical energy stored in capacitor C3 is sent from the positive terminal to the emitter of Q4 via variable resistor R8, and from the negative terminal to the base of Q4 via the winding of DC motor 25-13, the normally closed contact of jog button 25-12, and resistor R7. Q4 and Q5 are then turned on, supplying power to the cutting electromagnet 25-5 (variable resistor R8 in the diagram is used to adjust the working time of the cutting electromagnet 25-5). Cutting wire 9-5, a 5cm segment, interrupts the optical path, but it still allows identification of whether wire 9-5 is in position. This signal is transmitted through pin 2 of the five-pin connector. Figure 22 Pin 2 of one of P1~P5 in the power strip, or pins 15~20 of CT11 in the power strip, is connected to the system. If the system does not receive this signal within the set time (or the default value in "Factory Mode"), it will stop and alarm, indicating that wire 9-5 is missing. When this signal is sent back to the system, it will not affect the DC motor 25-13 driving the cutting solenoid 25-5 and the drive ball 28 to the ball 28-4 due to the logical AND gate blocking it. To ensure that wire 9-5 accurately enters the feeding hole 22-2, all wire cutters 25 are arranged in a straight line with uneven spacing. The column number of the feeding hole 22-2 is the value assigned in "Factory Mode" below. Figure 15 In this process, the A-type thread cutter 25 must be aligned with slot a. This is the basis for calculations in subsequent software development, and it is included in every power-on self-test. The more thread cutters 25 there are in the braiding machine, the faster the braiding progress.

[0071] The third step in processing line segment 9-7 is to... Feed hole 22-2 Line segment 9-7 is pushed into guide tube 24-3 by ejector plate 23 to change direction.

[0072] The function of the feeding plate 22-1 is to insert the ejector pin 23 on the body 23-3 between the ejector pin 23 and the guide tube inlet 28-7, and push the wire segment 9-7 in the feeding hole 22-2 through the guide tube outlet end 24-4 into the hook needle hole by the ejector pin 23-2 on the ejector pin 23.

[0073] The feeding plate 22-1 is a T-shaped steel plate with multiple feeding holes 22-2 arranged horizontally, their spacing corresponding one-to-one with the guide tube 24-3. The feeding holes 22-2 have a conical inlet 22-6, and the T-shaped steel at the outlet has a vertical light-transmitting hole 22-3, which communicates with the vertical light-transmitting hole 22-3 at the tail end of the feeding holes 22-2, ensuring that the wire 9-5 entering the feeding holes 22-2 blocks the light-transmitting hole 22-3, cutting off the light path. The cross-section of the T-shaped steel is shown below. Figure 8 As shown in section A, the feeding plate 22-1 is located on the long strip plate 28-11 on the back support frame 25-2. The vertical part of the T-shaped steel extends from the long slit 28-12 in the middle of the long strip plate 28-11, and the lower edge is threaded with teeth 28-10, which mesh with the turbine 28-9 coaxially connected to the stepper motor 24-13, driving the feeding plate 22-1 to slide left and right on the long strip plate 28-11 along the long slit 28-12. The two sides of the long slit 28-12 in the middle of the long strip plate 28-11 on the back support frame 25-2 are moderately fitted with the vertical part of the T-shaped plate, which has a guiding and limiting effect on the feeding plate 22-1. An infrared light-emitting diode 25-3 is located in the round hole on one side of the long strip plate 28-11.

[0074] In practice, the 2.5 mm diameter feeding hole 22-2 on the feeding plate 22-1 can be made by flaring a stainless steel tube and drilling a light-transmitting hole 22-3, and then bonding and fixing it to the upper surface of the T-shaped steel. Alternatively, it can be made by drilling a hole in the horizontal part of the T-shaped steel, which matches the head diameter of the ejector pin 23-2 on the ejector pin push plate 23. In this example, there are 800 such holes. Each feeding hole 22-2 is numbered and corresponds one-to-one with the column number of each pair of warp lines. The center distance is 3.81 mm. The light-transmitting hole 22-3 is an ellipse with a minor axis of 1.5 mm and a major axis of 2 mm. Its major axis coincides with the axis of the feeding hole 22-2.

[0075] The start, stop, and rotation direction of the stepper motor 24-13 are controlled by the system. When the feeding plate 22-1 moves from left to right, and the feeding hole 22-2 passes outside the wire cutter 25, and the light-transmitting hole 22-3 on the feeding plate 22-1 aligns with the infrared LED 25-3 glued to the round hole of the long strip plate 28-11 with AB glue, see... Figure 8As shown in AB, the photodiode 22-4 receives the infrared light signal and sends it to the input port of the control chip via the control circuit board 25-11. The system controls the stepper motor 24-13 to pause, and the feeding plate 22-1 has a dwell time of about 1 second. The feeding hole 22-2 receives wire segment 9-7 from the wire cutter 25. The dwell time is set in "factory mode," meaning that the feeding plate 22-1 moves intermittently from left to right. After all the feeding holes 22-2 have received material, the feeding plate 22-1 moves rapidly and continuously to the left. To prevent residual wax from clogging the light holes, after the feeding plate 22-1 finishes feeding, on the return stroke, the light-transmitting hole 22-3 passes through the high-pressure air jet port below the feeding plate 22-1, controlled by a solenoid valve, blowing air from bottom to top to remove residual wax.

[0076] The ejector plate 23 is made of angle iron, with guide rod holes 23-1 and two M6 mounting holes at both ends. Ejector pins 23-2, the same number as the feed holes 22-2, are threaded onto the front of the angle iron. The center (center) of the head of each ejector pin 23-2 is concave. Figure 5 As shown in B, to prevent the tail of line segment 9-7 from slipping to the edge and getting stuck on the wall of the feed hole 22-2, the tail of ejector pin 23-2 is threaded onto the ejector pin push plate 23. The guide rod holes 23-1 at both ends of the ejector pin push plate 23 slide longitudinally along the two guide rods 23-5, controlling the accurate entry and exit of each ejector pin 23-2 into the feed hole 22-2. See... Figure 5 As shown in Figure A, the mounting holes on the two base feet 22-5 of the type A bracket 32-4 are shown. Figure 12 As shown in Figure A, the two M6 mounting holes on the ejector plate 23 are bolted in. When the inlet 28-7 of the guide tube 24-3 aligns with the feed hole 22-2, the wire segment 9-7 is pushed through the guide tube 24-3 to change direction and enter the hook needle hole. The forward and backward movement of the ejector plate 23 is controlled by the output shaft of the permanent magnet synchronous motor 31-4 fixed on the body 23-3, coaxially connected to the screw 32-1 of the positive A-type bracket 32-4. The proximity electromagnetic switch 26-10 installed on the body 23-3 is shown in Figure A. Figure 15As shown, the control pin push plate 23 completes the wire supply, the permanent magnet synchronous motor 31-4 reverses and reaches the material waiting point of the pin push plate 23, the proximity electromagnetic switch 26-11 on the body 23-3 controls the permanent magnet synchronous motor 31-4 to stop, and the pin push plate 23 resets. If the even-numbered meridian 24-15 is in front, the proximity electromagnetic switch 26-8 is installed on the left side of the main body 23-3. The feeding plate 22-1 is detected by the proximity electromagnetic switch 26-8, the stepper motor 24-13 stops, and all feeding holes 22-2 are aligned with the guide tube inlet 28-7. The proximity electromagnetic switch 26-7 on the straight groove needle plate 12 controls the permanent magnet synchronous motor 31-4 to rotate forward. The guide tube outlet 24-4 is pulled by the traction electromagnet 24-10, aligning with the 90° needle hole 24-8 on the upper left and the left-leaning 60° needle hole 24-11. This causes the pusher plate 23 to push the wire segment 9-7 through the guide tube 24-3, through the right side of the 90° needle hole 24-8, and then through the left-leaning 60° needle hole 24-11. See Figure 17 As shown in Figure A. If the odd-numbered meridian 24-14 is in front, the proximity electromagnetic switch 26-8 system does not recognize it. All feeding holes 22-2 are aligned with the guide tube inlet 28-7. The feeding plate 22-1 drags the body 23-3 to overcome the resistance of the body spring 23-4 and continues to move to the left. When it encounters the proximity electromagnetic switch 26-9 installed on the left side of the back frame 25-2, which recognizes the body 23-3 in place, the stepper motor 24-13 stops. The proximity electromagnetic switch 26-7 controls the permanent magnet synchronous motor 31-4 to rotate forward. The guide tube outlet 24-4 is in its original direction, aligned with the 90° pin hole 24-8 and the right-tilted 60° pin hole 24-9 on the upper right. This causes the pusher plate 23 to push the wire segment 9-7 through the guide tube 24-3, through the left side of the 90° pin hole 24-8, and then through the right-tilted 60° pin hole 24-9. See Figure A. Figure 17 As shown in B. The main body 23-3 is an alloy aluminum square frame cast as one piece from the guide tube support 24-2 and the ejector pin push plate support, see... Figure 17 As shown in Figure C, two parallel cylindrical guide rods 23-5 are fixed at... Figure 17 C's main body 23-3 and Figure 6 In the cover plate 14-7 of A, there are two guide rod holes 23-1. Under the body 23-3, there are four support bearings 28-13. They move in the track formed by two channel steels 28-8. The channel steels 28-8 are fixed on the back frame 25-2.

[0077] The guiding mechanism, see Figure 6 As shown in Figure A, it includes a traction electromagnet 24-10, a traction rope 24-1, a traction spring 24-6, a lifting ring 24, and a guide tube 24-3 (see Figure A). Figure 6(As shown in B), guide tube bracket 24-2, cover plate 14-7. Multiple guide tubes 24-3 are arranged along the length of the guide tube bracket 24-2, and are mounted on the guide tube bracket 24-2 by the cover plate 14-7 via bolts 24-5 and 24-7. Each guide tube 24-3 is L-shaped, with its straight middle section rotatably connected to a circular hole formed by the guide tube bracket 24-2 and the cover plate 14-7. One end of the traction rope 24-1 is connected to a traction spring 24-6 fixed on the body 23-3, tightly passes through the lifting ring 24 hole located below each guide tube 24-3, and is fixed with elastic polyurethane adhesive. The other end is connected to the ground iron in the traction electromagnet 24-10 fixed on the guide tube bracket 24-2. The guide tubes 24-3 and the lifting rings 24 are welded together using easily weldable 304 stainless steel. (See...) Figure 6 As shown in Figure B, the traction rope 24-1 is made of nylon rope with good adhesive properties. Because the carpet weave has an approximately 10° vertical (Z-axis) inclination, the angle between the inlet and outlet of the guide tube 24-3 is 90° (Z-axis). The two matching pinholes are staggered by 20°, resulting in a total 120° change in direction for the guide tube. Therefore, the guide tube 24-3 is made of a 2.5 mm inner diameter stainless steel tube with a smooth inner wall (the waxed wire segment 9-7 is less than 2 mm), bent to a 120° rounded corner, with a total length of 3 cm (wire segment 9-7 is 5 cm long). In this example, there are 800 of these. The guide tube 24-3 is installed horizontally. When the traction electromagnet 24-10 is energized, the outlet end 24-4 faces upwards to the left; when not energized, the outlet end 24-4 faces upwards to the right. See Figure B. Figure 17 As shown in AB.

[0078] The fourth step is to take the multiple numbered 9-7 yarn segments that have entered the eye of the crochet hook and form an 8-knot on a pair of front and back warp threads.

[0079] Since the yarn segment 9-7, which comes out from the guide tube outlet 24-4, is either pointing to the upper left or the upper right, the pair of needle holes that cross the warp need to be set one above the other (Y-axis angle 60°). The two crossing needles are not close together, but have a certain vertical distance, so that the line connecting the two needle holes is in a " / " (left lower, right higher) or "\" (left higher, right lower) state. If the odd-numbered warp 24-14 is in front, the 60° right-leaning needle works in conjunction with the 90° needle, and the straight groove needle plate 12 is at the bottom, the two needle holes are in a " / " (left lower, right higher) state relative to each other. Yarn segment 9-7 needs to pass through the needle hole to the upper right. The arrangement of yarn segment 9-7 on the back of the knitting fabric is shown in the rear view. Figure 20 B ( Figure 20 The marked warp is the back warp; the front warp is not marked. If even-numbered warp threads 24-15 are in front, the needles work at a 60° left angle in conjunction with 90° needles, with the two needle holes facing each other in a "\" (left higher than right) position. Yarn segment 9-7 needs to be inserted into the needle hole to the upper left. See the rear view for the arrangement of yarn segment 9-7 on the knitting fabric. Figure 20 A. The two needle holes are positioned one in front of the other along the Z-axis (the 60° angled needle hole is closer to the warp, while the 90° needle hole 24-8 is farther from the warp, with a vertical angle of 20° (the angle between the Z-axis and the Y-axis). This causes the two needle holes to be misaligned and cannot be aligned. Increasing the length and width of the needle holes to 6×4 mm, which is 2.6 to 4 times the diameter of line segment 9-7, allows the head of line segment 9-7 to pass smoothly through the 90° needle hole 24-8 and then through the left-leaning 60° needle hole 24-11. The distance between the crossing needles should be adjusted so that each line segment 9-7 does not squeeze or interfere with each other.

[0080] To achieve the above objectives, the specific component includes a left-tilting needle plate 11 (see below). Figure 10 As shown in A, see right-leaning needle plate 13. Figure 10 As shown in B, see straight groove needle plate 12. Figure 10 As shown in C, see Z-shaped track slab 32-6. Figure 10 As shown in D, see left-leaning rhomboid slider 29. Figure 11 As shown in C, see right-leaning rhomboid slider 29-1. Figure 11 As shown in B, see the rectangular slider 30. Figure 11 As shown in Figure A, see type A bracket 32-4. Figure 12 As shown in Figure A, see the two inclined A-type brackets (see 32-5). Figure 12 As shown in Figure B, permanent magnet synchronous motors 31-1, 31-2, and 31-3 work together to complete the operation. The left-inclined needle plate 11 has multiple inclined slots at a 60° leftward angle, the right-inclined needle plate 13 has multiple inclined slots at a 60° rightward angle, and the straight-groove needle plate 12 has multiple straight slots perpendicular to its two long sides. The inclined slots on the left-inclined needle plate 11 and the right-inclined needle plate 13 are laterally spaced from the straight slots on the straight-groove needle plate 12, and each slot number on the straight-groove needle plate 12 corresponds to the column position number of each pair of warp lines. The hook needle holes placed in the inclined slots of the left-inclined needle plate 11 are called left-inclined 60° needle holes 24-11, the hook needle holes placed in the inclined slots of the right-inclined needle plate 13 are called right-inclined 60° needle holes 24-9, and the hook needle holes placed in the straight-groove needle plate 12 are called 90° needle holes 24-8.

[0081] To make the crochet hook reciprocate within the needle groove, each needle plate has a sliding block made of steel plate. In the middle of each sliding block is a long needle foot frame 29-2, see... Figure 11As shown, Z-shaped track plates 32-6 and 32-7 are located at both ends of the 60° left-tilted needle plate; Z-shaped track plates 32-8 and 32-9 are located at both ends of the 60° right-tilted needle plate; and Z-shaped track plates 32-10 and 32-11 are located at both ends of the straight groove needle plate. These track plates, together with the needle plates, form track grooves. The slider slides within these grooves. The mounting holes on the two bases 22-5 of the two A-shaped brackets are fixed to the two M6 holes of the three shapes of sliders using bolts. The rectangular slider 30 is supported by a positive A-shaped bracket 32-4. The left-tilted rhomboid slider 29 and the right-tilted rhomboid slider 29-1 both use oblique A-shaped brackets 32-5 and are installed using a front and back mounting method. The needle frame 29-2 in the middle of the slider is into which the hook needle 24-12 is inserted and fixed with AB glue to prevent the needle 24-12 from breaking due to the shear stress formed by the slider and the needle plate, thus improving the accuracy and lifespan of the mechanism. On the top of the two types of A-shaped brackets and on the cross brace 8-2, there is a threaded hole 32-2 and a threaded hole 32-3. The screw 32-1 is driven by a permanent magnet synchronous motor inside, rotating in both directions within the threaded holes 32-2 and 32-3, thus pushing and pulling the slider forward and backward. On the upper rear side of the left-tilting needle plate 11 and the right-tilting needle plate 13, there are proximity electromagnetic switches 26-5 and 26-6, respectively, which control a permanent magnet synchronous motor on the corresponding needle plate and permanent magnet synchronous motor 31-3 on the straight groove needle plate 12 to reset and stop the hook. On the upper front side of the straight groove needle plate 12, there is a proximity electromagnetic switch 26-7, which controls permanent magnet synchronous motors 31-1, 31-2, and 31-3 on the three needle plates to stop the hook at the thread position. If the feeding plate 22-1 or the body 23-3 has reached the thread supply position, it also controls permanent magnet synchronous motor 31-4 to be energized and rotate forward, driving the pusher plate 23 to reach the thread supply position.

[0082] In practice, the three needle plates in the knitting machine are arranged in the following order from top to bottom: left-tilted needle plate 11, right-tilted needle plate 13, and straight-groove needle plate 12, which are horizontally mounted on the front support bracket 32. (See...) Figure 1 Figure 16As shown, both ends of the needle plate are fixed with bolts. The plane of the right-leaning needle plate 13, located in the middle, is perpendicular to the knitting width. The angle between the plane of the right-leaning needle plate 13 and the plane of the left-leaning needle plate 11 above it is approximately 15° and adjustable. This ensures that when the hook needle in the left-leaning needle plate 11 reaches the yarn position, it is nearly horizontal with the hook needle in the right-leaning needle plate 13 below it. The grooves of the three needle plates face upwards. The straight groove needle plate 12 is installed below the right-leaning needle plate 13, and the angle between adjacent needle plate planes is adjustable at 10°. During operation, the hook needle in the straight groove needle plate 12 cooperates with the hook needle in another oblique groove needle plate, and the hook needle slides back and forth in the groove. The hook needle in the idle oblique groove needle plate, after being changed back and forth, is used in conjunction with the hook needle in the straight groove needle plate 12. In other words, the two oblique groove needle plates work in turn with the straight groove needle plate 12.

[0083] In this example, all three needle plates have 800 grooves because a 160-type carpet has 160 warp threads per foot, which is divided into front and back warp threads, each with 80 threads. A 10-foot carpet has 800 threads, and the two grooves are 3.81 millimeters apart. Because the 5cm long yarn segment 9-7, after being wrapped around the front and back warps to form an "8" shape, is equivalent to folding the yarn segment 9-7 to a length of 2.5cm. To ensure that the 8 does not hit the needle plate when descending and to prevent the needle groove from catching the yarn when the hook pulls back, a 5cm width is left on the long side of the 8. Adding the 2.5cm length of the yarn segment 9-7, the total is 7.5cm. This is the distance the hook travels within the groove. To ensure the stability of the hook within the groove, the groove length should be approximately twice this value. Therefore, it is designed with through grooves on a 20cm wide steel plate, with a straight groove length of 20cm and an angled groove length of 23.1cm. The hook placed in the straight groove is 14.5cm long, and the hooks placed in the other two needle plates are 17cm long. The hook body thickness is 1mm, and the groove width is 1.5mm. It is made of steel.

[0084] If the odd-numbered meridians are 24-14 first, see Figure 13 As shown in Figure A, after a 90° crochet hook and a 60° right-leaning crochet hook cross, they serve a pair of front and back warp threads. After the warp threads are reversed, the even-numbered warp threads 24-15 are in front. Figure 13 As shown in Figure B, although the 90° needle passes directly between the front and back warp threads without changing its position, it requires a 60° leftward tilt to work in conjunction with the 90° hook. Therefore, we conclude that a 60° rightward tilt hook works with odd-numbered warp threads 24-14 in front, and a 60° leftward tilt hook works with even-numbered warp threads 24-15 in front. This invention is implemented based on this principle. The upper wall of the hook hole is wider, and the lower wall is narrower, with the same thickness as the needle body, facilitating the insertion of thread segment 9-7. The two types of hooks work in a cross shape, with the front and back warp threads located within the apex of the cross. The hooks in the 60° leftward and 60° rightward tilt needle plates alternately work with the hooks in the straight groove needle plate, pulling thread segment 9-7 around the front and back warp threads in a figure-eight shape. Figure 13As shown.

[0085] As described above, line segment 9-7 first passes diagonally into the 90° needle hole 24-8, and then into the 60° needle hole. The straight lines formed by the horizontal "I" shape of each 90° hook head should be offset from the straight lines arranged at the line outlet 24-4 of the guide tube 24-3 below. The distance is adjustable to control the length of line segment 9-7 passing through the two needle holes. In practice, the main adjustment is to adjust the mating distance between the body 23-3 and the straight groove needle plate, and the secondary adjustment is to adjust the depth of the ejector pin 23-2 on the ejector pin push plate 23 as it passes through the feeding hole 22-2 and then enters the guide tube 24-3. That is, the secondary adjustment is to adjust the front and rear positions of the proximity electromagnetic switch + 26-10, so that the two ends of line segment 9-7 are on the front of the carpet, that is, the pile side of the carpet, and are aligned after being tightened by the upper pressure plate 9 and the lower bottom plate 10 to form a figure-eight knot.

[0086] The edge-wrapping mechanism involves wrapping the two pairs of thick warp threads on both sides of the woven fabric. This process is performed simultaneously with the fourth step, and the two pairs of thick warp threads are not reversed. The edge-wrapping mechanism includes a left edge wrapper and a right edge wrapper. The two edge wrappers have the same structure but are opposite in direction. Figure 19As shown, the two edge wrappers operate on the left and right sides of the weaving width. They are fixedly connected to the square steel 33-9 and the two knife-shaped brackets 33-4 by bolts through angle iron 33-10 and angle iron 33-11 respectively. The two ends of the square steel 33-9 are connected to the front of the upper end of the left front support 1 and the right front support 1-1 by bearings, located above the straight groove bar 4. On the right end of the square steel 33-9, outside the right front support 1-1, an edge wrapping driven gear 33-12 is fixedly connected, which meshes with the edge wrapping drive gear 33-13 coaxially connected to the edge wrapping motor 33-14. The edge wrapping motor 33-14 is bolted to the bottom of the crossbeam 1-3. The blade-shaped support 33-4 is fixed as a single unit to the hollow shaft 33-2. The notched gear 33-3 is slidably and rotatably connected to the hollow shaft 33-2. The cylinder 33-1 is fixedly connected to the notched gear 33-3. The spool 33 is slidably connected to the cylinder 33-1 and rotates with the notched gear 33-3. The winding thread stored in the spool 33 is wound onto the two thicker edge warps via a pick spring 33-8 made of fine steel wire to prevent the winding thread from loosening. When the blade-shaped support 33-4 is on the left-tilting needle plate 11... When the two thick edge warps are inserted into the inner side, they are spread outwards. The two thick edge warps slide along the oblique edge of the blade-type bracket 33-4 towards the center of the hollow shaft 33-2 with a notch. The edge-winding gear 33-5, fixed on the output shaft of the micro motor 33-6, meshes with the notched gear 33-3 of the left edge winder, driving the spool 33 to rotate around the two edge warps, winding the edge-winding thread onto the two thick edge warps in a fixed number of turns. Then, the next step of passing the thick and thin weft threads connects the two pairs of thick edge warps to the carpet width as one unit. The method of driving the right edge winder with the micro motor 33-7 is the same as that of the left edge winder.The proximity electromagnetic switch 26-7 controls the simultaneous activation of the edge-wrapping motor 33-14 and the limit electromagnet 33-15 mounted on the right front support column 1-1. The limit electromagnet 33-15 retracts, and the limit iron 33-16, welded to the square steel 33-9, loses its support. Driven by the edge-wrapping motor 33-14, the square steel rotates forward, causing the two edge-wrapping devices to rotate downwards. The thick edges inserted into the carpet pass through the inner side and enter through the notch in the hollow shaft 33-2. The proximity electromagnetic switch 33-17, mounted on the right front support column 1-1, senses the limit iron 33-16 and activates the micro motors 33-6 and 33-7, stopping the edge-wrapping motor 33-14. Proximity electromagnetic switches 15-26-15 and 16-26-16, mounted on two blade-shaped supports 33-4, are connected to two counters in the system and count the turns. These counters control micro motors 1-33-6 and 2-33-7 to stop winding after a certain number of turns. The notch on the notched gear 33-3 aligns with the notch on the blade-shaped support 33-4. Simultaneously, the counters control the edge-winding motor 33-14 to reverse, causing the thick edge to exit through the notch on the notched gear 33-3. Proximity electromagnetic switch 18-26-18, mounted on the right front support 1-1, senses the limit iron 33-16, de-energizing the edge-winding motor 33-14 and the limit electromagnet 33-15, resetting the limit iron, and locking the limit iron 33-16. The number of winding turns is set in the production mode. Due to the use of an overhead rotating structure, to reduce rotational inertia, the edge winder, except for the lifting spring 33-8, is made of lightweight materials such as aluminum alloy and nylon.

[0087] This invention uses the vertical weaving width of the carpet as the boundary. The platform in front of the width is the front support frame 32, and the platform behind the width is the back support frame 25-2. The front support frame is fixedly connected to the left front support column 1 and the right front support column 1-1 by screws. The back support frame is fixedly connected to the left front support column 2-1 and the right front support column 2-2 by screws. The various mechanisms on the front and back supports cooperate to perform the weaving operation on the width. The shuttle rod passes between the right front support column 1-1 and the right front support column 2-2 to perform the shuttle insertion operation, cooperating with four shuttle magazines to pass through the thick and thin weft and warp threads. The front support frame 32 supports three needle plates and three permanent magnet synchronous motors for driving the sliders: permanent magnet synchronous motor 1 31-1, permanent magnet synchronous motor 2 31-2, and permanent magnet synchronous motor 31-3, as shown in the diagram. Figure 16As shown. The back support frame 25-2 supports the main body 23-3, multiple thread cutters 25, feeding plate 22-1, ejector pin push plate 23, high-pressure air nozzle, stepper motor 24-13, crank-connecting rod mechanism, linkage mechanism that works with kite 6 to complete the front and rear diameter change, carpet rolling mechanism, wax pool 27, and thread supply system for wire 9-5 (not shown). It should be noted that in order for the inner front side of the pawl 8 to be close to the warp thread and the rear side raised when the pawl 8 is at the bottom dead center, the two rear support columns 2 must have sufficient height to connect the swing arm 20. The pivot connection point of the swing arm 20 is the center of the circle where the pawl 8 makes an approximate arc motion. Raising this height is equivalent to raising the inner front long side of the pawl 8 to be close to the warp thread when it is at the bottom dead center, preventing the outer edge from hitting the left tilting needle plate 11. The transmission shaft 16 in the crank-connecting rod mechanism is installed at the bottom. Since the asynchronous motor 17 is also at the bottom, close to the ground, the center of gravity is lowered, which increases the stability of the entire machine and facilitates installation.

[0088] The wire 9-5 inside the wire cutter is selected to enter the feeding hole 22-2. The code and algorithm of the software system are based on the number of wire cutters 25 and the number of feeding holes 22-2. If the width is wide and there are fewer wire cutters 25, the weaving progress is slow. If the width is narrow and there are more wire cutters 25, the weaving progress is fast. Increasing the number of wire cutters 25 can speed up the weaving progress of the machine.

[0089] The following explains how to operate this machine:

[0090] I. Preparation

[0091] Write a driver program for the machine, load it onto the microcomputer, and send the carpet pattern drawing composed of line segments 9-7 to the carpet weaving machine via the Internet of Things or a USB flash drive, or manually input the paper drawing information in production mode.

[0092] The process of making carpet is as follows: Weaving the first part of the carpet: passing the warp threads (placing warp tassels in the coarse weft shuttle box, using the warp threads as weft threads) - front and back warp changes - passing the warp threads - front and back warp changes (can be done manually or automatically, repeated several times, commonly known as "base layering"). After passing five to six rows of warp threads, lock the base by alternately passing the fine weft and warp threads, weaving about half an inch. When completing the last passing of the fine weft threads, do not change the front and back warp threads. In the coarse weft shuttle box, replace the previous warp tassels with coarse weft tassels, and tie the ends of the threads together. Remove the stainless steel strips 6-2 controlling the coarse edge warp on both sides of the odd-numbered shuttle 6 and even-numbered shuttle 6-1, and hang them up to fix them as the front and back warp. According to the carpet design drawings, install the numbered segment 9-7, while simultaneously using the two edge wrappers on the left and right. The numbered segment 9-7 should be tied with a pair of front and back warp threads in a figure-eight knot. After installing one row of numbered segment 9-7, pass the coarse weft thread, change the front and back warp threads, and then pass the fine weft thread. In other words, two weft threads, one thin and one thick, directly sandwich the 9-7 yarn segment in the middle, without any warp-to-back transition. The various colored 9-7 yarn segments are the most basic units that make up the carpet pattern. The weaving process at the end of the carpet is the same as at the beginning.

[0093] II. System and Workflow Introduction:

[0094] The system consists of hardware such as software, microcontroller, expansion chip, memory, color display screen, keyboard, mouse, and USB communication interface. The drawing information of the carpet cutting is stored in it. It processes the photoelectric signals sent from various proximity electromagnetic switches and photodiodes 22-4, and controls the start and stop of each wire cutter 25, traction electromagnet, and the start, stop and rotation direction of all permanent magnet synchronous motors, micro motors, asynchronous motors 17, DC motors and stepper motors 24-13. It is the core of the entire machine.

[0095] 1. Power on the device, press the combination keys to enter the password, and enter the "Factory Mode" settings.

[0096] 2. Set the column position of each wire cutter 25, i.e., position "0", which is the column position corresponding to the original position of the feed hole 22-2. During programming, the column position number is represented by lowercase English letters in sequential order. Each pair of warp threads occupies one column position, and each row number segment 9-7 occupies one row position, represented by Arabic numerals in sequential order. Each wire cutter 25 is named in sequential uppercase English letters, for example... Figure 15 When wire cutter A 25 feeds out wire segment 9-7, the corresponding feeding hole 22-2 is 'a', denoted as A=a. When wire cutter B 25 outputs wire, the corresponding feeding hole 22-2 is 'd', denoted as B=d. This process continues until each wire cutter 25 is assigned a value. Then, set the forward and reverse rotation duration of stepper motor 24-13, and the waiting time for feed plate 22-1 and hook needle when photodiode 22-4 receives information from infrared LED 25-3. Exit "Factory Mode".

[0097] 3. The microcomputer transmits drawing information to the system's memory via network, USB port, USB flash drive, or manually.

[0098] 4. Since the yarns of various colors have been numbered in advance, enter the "Production Mode" settings. Manually input the position of each yarn number on the yarn cutter 25. For example, if yarn #3 is on yarn cutter 25 A, record it as A=3; if yarn #12 is on yarn cutter 25 B, record it as B=12. This assigns a yarn number value to each yarn cutter 25, which is equivalent to assigning a yarn color number. This assignment has a different meaning than the assignment in factory mode. One assigns a value to the position of yarn cutter 25, while the other assigns a yarn number value to yarn cutter 25 and introduces the corresponding yarn number 9-5 onto the corresponding yarn cutter 25. Press the jog button 25-12 on the yarn cutter 25. See... Figure 8 Electrical principles Figure 21 As shown, a 24-volt power supply powers the DC motor 25-13 through a normally open contact, leading wire 9-5 into the material holding groove 22 of the toothed conveyor belt 20-2, between blade 25-9 and dovetail blade 25-4. Set the number of wrapping turns and exit "production mode".

[0099] 5. The microcontroller system compares the wire number from the drawing data and the manually input wire number, and controls the wire cutter 25, the hook push and pull, the up and down movement of the needle 8, the front and back warp changes of the needle 6, and the weft passing.

[0100] 6. Line 9-5 is out of wire alarm, hook waiting timeout alarm, and the machine stops.

[0101] 7. Displays the working progress and fault codes.

[0102] 8. Breakpoint protection: It has a power-off memory function.

[0103] III. The overall working process of the machine is briefly described as follows;

[0104] (i) As described in the Preparation, place the warp tassels in the shuttle box in the front right shuttle box 14-1, and place the fine weft tassels in the shuttle box in the rear right shuttle box 14-10.

[0105] (II) Weave the beginning of the carpet using the function keys. After finishing the base and locking the base, replace the previous warp tassels with thick weft tassels and tie the ends of the threads together. Tie the two edge threads on the left and right sides together with their respective pairs of thick edge warps and tie a knot. Remove the stainless steel strips 6-2 that control the thick edge warps on the odd-numbered kite 6 and even-numbered kite 6-1, hang up the two pairs of thick edge warps, and fix them at the distance between the front and back warps that the shuttle box can pass through.

[0106] (III) Press the Run button to enter the automatic carpet weaving program.

[0107] (iv) After the automatic weaving is completed, stop the machine, restore the stainless steel strip 6-2 that controls the thick edge warp to the odd-numbered warp 6 and even-numbered warp 6-1, replace the previous thick weft tassel with the warp tassel, tie the ends of the threads together, tie a knot on each of the two edge wrapping threads on their respective pair of thick edge warps, and cut the remaining edge wrapping threads. Press the function key to weave the end of the carpet, make the base and lock the base, and finally complete the work.

[0108] There are two startup scenarios: one is the initial carpet weaving, as mentioned above, which requires weaving the carpet head and setting up; the other is starting the machine midway after it has been stopped. The following describes the second startup scenario:

[0109] Upon power-on, the system board performs a self-test, generating alarm messages and hook reset signals. It reads memory data, including drawing information and front / back warp information: whether odd-numbered warp 24-14 or even-numbered warp 24-15 is used as the front warp. This determines whether the hook in the left-leaning needle plate 11 works in conjunction with the hook in the straight-groove needle plate 12, or vice versa. It compares the current progress information, reads breakpoint protection information, determines the starting position, and displays the row number of line segment 9-7 (named sequentially with Arabic numerals). It searches for the same line number 9-5. If not found, an alarm prompts that line number 9-5 needs to be added, or the system enters production mode to reset. Since some line numbers 9-5 are temporarily unused, they can be replaced with more frequently used lines at that position to cover the original line number. Adding an additional thread cutter 25 will speed up the machine's weaving progress.

[0110] Tip 1: Odd-numbered meridians come first.

[0111] 2. Spread the meridians: Press the Run button. If the system determines that odd-numbered meridians 24-14 need to be placed first, see... Figure 13 A. The stepper motor 24-13 is controlled to rotate forward via instruction code, driving the feed plate 22-1 to drag the main body 23-3 to the line position. Upon encountering the proximity electromagnetic switch 26-9, the stepper motor 24-13 stops, waiting for the hook to arrive. Due to the pull of the traction spring 24-6, the guide tube 24-3's line outlet 24-4 faces the original position to the upper right. The proximity electromagnetic switch 26 recognizes that the guide tube 24-13 is at its upper stop point, controlling the traction electromagnet 6-4, which is in front of the odd-numbered guide tube 6, to be energized. See Figure 2 As shown in B, the meridians are spread out.

[0112] 3. Needle Insertion: Proximity electromagnetic switch 26 simultaneously controls permanent magnet synchronous motors 2 and 31-3 to rotate forward, driving the hooks in the right-tilting needle plate 13 and straight groove needle plate 12 to the threading position. After proximity electromagnetic switch 7 26-7 identifies the position, it controls permanent magnet synchronous motors 2 and 31-3 to stop, and controls traction electromagnet 1 6-4 to de-energize, limit electromagnet 33-15 to energize, and snagging motor 33-14 to rotate forward to perform snagging operations. The two needles are reset, and the system identifies proximity electromagnetic switch 9 26-9. If the proximity electromagnetic switch 26-9 installed on the back rack 25-2 does not recognize the arrival information of the main body 23-3, the hook needle will wait for material for a delay and then alarm and stop the machine after the timeout. If the arrival information of the main body 23-3 is recognized, the proximity electromagnetic switch 26-7 controls the permanent magnet synchronous motor 31-4 of the push plate 23 to be energized and rotate forward. The push plate 23-2 will send the wire segment 9-7 through the guide tube 24-3 into the two hook needle holes.

[0113] The edge-winding operation is carried out simultaneously with the carpet cutting operation and is an independent auxiliary mechanism that is not closely related to the whole machine. For specific implementation details, please refer to the aforementioned edge-winding mechanism. It will not be described again during the operation of the whole machine.

[0114] 4. When the push plate 23 feeds all the thread segments 9-7 into the hook hole, the proximity electromagnetic switch 26-10 installed on the body 23-3 controls the permanent magnet synchronous motor 31-4 to reverse, and the proximity electromagnetic switch 26-11 detects the push plate 23 and controls the permanent magnet synchronous motor 31-4 to stop, and the push plate 23 is reset.

[0115] The proximity electromagnetic switch 26-11 simultaneously controls the stepper motor 24-13 to reverse, driving the feeding holes 22-2 on the feeding plate 22-1 to the wire cutter 25 to receive the next row of wire segment 9-7. After all feeding holes 22-2 have received the next row of wire segment 9-7, the system controls the stepper motor 24-13 to rotate forward via instruction code, driving the feeding plate 22-1 to the wire supply position before the guide tube inlet 28-7. Upon encountering the proximity electromagnetic switch 26-8, the stepper motor 24-13 stops, energizing the traction electromagnet 24-10, pulling the guide tube outlet 24-4 of the lifting ring 24 towards the upper left. After the front and rear diameters change, it waits for the hook to arrive.

[0116] 5. Needle Retraction: While the proximity electromagnetic switch 26-10 controls the permanent magnet synchronous motor 31-4 to reverse, it also controls the permanent magnet synchronous motors 31-2 and 31-3 to reverse, driving the hooks in the right-tilting needle plate 13 and straight groove needle plate 12 to pull back the beginning and end of the thread segment 9-7 located in the needle hole to the front of the carpet. The thread segment 9-7 forms a figure-eight knot on the front and back warp threads. The proximity electromagnetic switch 26-6 recognizes the right-tilting diamond slider 29-1 and controls the permanent magnet synchronous motors 31-2 and 31-3 to stop, and the hooks reset.

[0117] 6. Compacting the No. 8 Line: The proximity electromagnetic switch 26-6 simultaneously controls the asynchronous motor 17 to start, causing line 8 to descend and compact all line segments 9-7. The proximity electromagnetic switch 26-1 installed at the lower stop point controls the winding and storage shaft 35 and the winding and storage motor 37 to start. The brake electromagnet 36 on the winding and storage shaft 35 momentarily releases and then brakes, de-energizing the winding and storage motor 37. Simultaneously, the upper pressure plate 9, in conjunction with the lower base plate 10, tightens line segments 9-7. (See...) Figure 4 As shown, the asynchronous motor 17 continues to rotate. When the base plate 8 reaches the top dead center, the proximity electromagnetic switch 26 sends a positioning signal to the system board, the asynchronous motor 17 is de-energized, the base plate 8 is reset, and the lower base plate 10 is reset by the rotation spring 9-4 and the spring shaft 9-6.

[0118] 7. Spreading the warp: The proximity electromagnetic switch 26 detects that the warp 8 has reached the upper stop point, and at the same time controls the traction electromagnet 6-4 in front of the odd-numbered warp 6 to be energized, spreading the warp.

[0119] 8. Passing the coarse weft yarn: The proximity electromagnetic switch 26 simultaneously controls the arrow shaft motor 15-7, the shuttle coil 15-3, and the micro motor 14-6 to rotate forward, driving the right shuttle magazine 14-1 and the left shuttle magazine 14, which contain the coarse weft yarn box, to rotate upward synchronously by 90°, reaching the supply and receiving positions respectively. The proximity electromagnetic switch 26-4 then controls the motor 14-6 to stop rotating. The arrow shaft 15-1 pushes the shuttle magazine containing the coarse weft yarn tassel from the right shuttle magazine 14-1 through the front and rear warp threads into the left shuttle magazine 14. Hall effect proximity electromagnetic switch 26-2 controls the arrow shaft motor 15-7 to reverse, the shuttle coil 15-3 is de-energized after a delay and then energized again, the arrow shaft 15-1 discards the coarse weft shuttle box, Hall effect proximity electromagnetic switch 36-3 controls the arrow shaft motor 15-7 to de-energize, the arrow shaft 15-1 resets, completes the passage of the coarse weft thread, and controls the micro motor 14-6 to reverse, proximity electromagnetic switch 1226-12 controls the micro motor 14-6 to stop, and the two pairs of shuttle boxes are idle in a longitudinal horizontal state.

[0120] 9. Warp Reset and Compaction: The proximity electromagnetic switch 26-12 simultaneously de-energizes the traction electromagnet 6-4 and starts the asynchronous motor 17, resetting the warp. The warp 8 descends to compact the coarse weft and reset. The brake electromagnet 36 on the winding and storage shaft 35 is controlled by the proximity electromagnetic switch 26-1 installed at the lower stop of the warp 8. When the warp 8 reaches the lower stop, it momentarily releases and brakes. When the proximity electromagnetic switch 26 detects that the warp 8 has reached the upper stop, it controls the asynchronous motor 17 to stop.

[0121] 10. Front and back meridian transformation: The proximity electromagnetic switch 26 simultaneously controls the traction electromagnet 2 6-5 of the even-numbered kite 6-1 to be energized, with the even-numbered meridian 24-15 in front, completing the front and back meridian transformation.

[0122] Tip 2: Even-numbered meridians come first.

[0123] 11. For fine weft threads: The proximity electromagnetic switch 26 simultaneously controls the arrow shaft motor 15-7, the shuttle coil 15-3, and the micro motor 14-6 to reverse and energize them. See [link / description]. Figure 18 As shown in F, the left shuttle magazine 14-9 and the right shuttle magazine 14-10, which contains the fine weft shuttle box, are driven to rotate synchronously upward by 90°, reaching the shuttle supply position and the shuttle receiving position respectively. The proximity electromagnetic switch 26-4 controls the micro motor 14-6 to stop rotating. Arrow shaft 15-1 pushes the shuttle box containing the fine weft yarn in right shuttle box 14-10 through the warp threads and into left shuttle box 14-9. Hall effect proximity electromagnetic switch 13 26-13 controls arrow shaft motor 15-7 to reverse and shuttle suction coil 15-3 to be de-energized after a delay and then re-energized. Arrow shaft 15-1 discards the fine weft yarn shuttle box. Hall effect proximity electromagnetic switch 14 26-14 controls arrow shaft motor 15-7 to stop and shuttle suction coil 15-3 to be de-energized. Arrow shaft 15-1 resets, completing the passage of the fine weft yarn, and controls micro motor 14-6 to rotate forward. Proximity electromagnetic switch 12 26-12 controls micro motor 14-6 to stop, and both pairs of shuttle boxes are idle in a longitudinal horizontal state.

[0124] 12. Warp Reset and Compaction: The proximity solenoid switch 26-12 simultaneously de-energizes the traction electromagnet 26-5, starts the asynchronous motor 17, and resets the warp, causing the warp 8 to descend and compact the fine weft yarn before resetting. The brake electromagnet 36 on the winding and storage shaft 35 is controlled by the proximity solenoid switch 26-1 installed at the lower stop point of the warp. When the warp 8 reaches the lower stop point, it momentarily releases and then brakes. When the proximity solenoid switch 26 detects that the warp 8 has reached the upper stop point, it controls the asynchronous motor 17 to stop.

[0125] 13. Spreading the warp threads: The proximity electromagnetic switch 26 simultaneously controls the traction electromagnet 2 6-5 of the even-numbered kite 6-1 to be energized, thus spreading the warp threads.

[0126] 14. Needle Insertion: The proximity electromagnetic switch 26 simultaneously controls the forward rotation of permanent magnet synchronous motors 31-1 and 31-3, driving the hooks in the left-tilting needle plate 11 and straight groove needle plate 12 to the threading position. After the proximity electromagnetic switch 26-7 identifies the position, it controls the permanent magnet synchronous motors 31-1 and 31-3 to stop, and controls the traction electromagnet 6-5 to be de-energized. The two needles reset, the limit electromagnet 33-15 is energized, and the sewing motor 33-14 rotates forward to perform sewing operations. The system identifies the proximity electromagnetic switch 26-8.

[0127] 15. Threading the Numbered Line Segment: If the proximity electromagnetic switch 26-8 installed on the main body 23-3 does not recognize the arrival information of the feeding plate 22-1, the hook needle will wait for the material for a delay and then alarm and stop the machine after the timeout. If the arrival information of the feeding plate 22-1 is recognized, the proximity electromagnetic switch 26-7 controls the permanent magnet synchronous motor 31-4 of the push plate 23 to be energized and rotated in the forward direction. The push plate 23-2 will send the numbered line segment 9-7 through the guide tube 24-3 into the two hook needle holes.

[0128] 16. When the push plate 23 feeds all the thread segments 9-7 into the hook hole, the proximity electromagnetic switch 26-10 installed on the body 23-3 controls the permanent magnet synchronous motor 31-4 to reverse, and the proximity electromagnetic switch 26-11 detects the push plate 23 and controls the permanent magnet synchronous motor 31-4 to stop, and the push plate 23 is reset.

[0129] The proximity electromagnetic switch 26-11 simultaneously controls the stepper motor 24-13 to reverse, driving the feeding holes 22-2 on the feeding plate 22-1 to the wire cutter 25 to receive the next row of wire segment 9-7. After all feeding holes 22-2 have received wire segment 9-7, the system controls the stepper motor 24-13 to rotate forward via instruction code, driving the feeding plate 22-1 to drag the main body 23-3 to the wire supply position. Upon encountering the proximity electromagnetic switch 26-9, the stepper motor 24-13 stops, and the guide tube 24-3, due to the pull of the traction spring 24-6, has its wire outlet end 24-4 facing the original position to the upper right. After the front and rear diameters change, it waits for the arrival of the hook.

[0130] 17. Needle Retraction: While the proximity electromagnetic switch 26-10 controls the permanent magnet synchronous motor 31-4 to reverse, it also controls the permanent magnet synchronous motors 31-1 and 31-3 to reverse, driving the hooks in the right-tilting needle plate 13 and straight groove needle plate 12 to pull back the beginning and end of the thread segment 9-7 located in the needle hole to the front of the carpet. The thread segment 9-7 forms a figure-eight knot on the front and back warp lines. The proximity electromagnetic switch 26-5 recognizes the left-tilting diamond slider 29-1 and controls the permanent magnet synchronous motors 31-1 and 31-3 to stop, and the hooks reset.

[0131] 18. Compacting: Proximity electromagnetic switch 26-5 simultaneously controls the asynchronous motor 17 to start, compacting section 9-7 of line 8 downwards. Proximity electromagnetic switch 26-1 installed at the lower stop controls the winding and storage shaft 35 and the winding and storage motor 37 to start. The brake electromagnet 36 on the winding and storage shaft 35 momentarily releases and then brakes, de-energizing the winding and storage motor 37. At the same time, the upper pressure plate 9, in conjunction with the lower base plate 10, tightens section 9-7. See Figure 4 As shown, the asynchronous motor 17 continues to rotate. When the base plate 8 reaches the top dead center, the proximity electromagnetic switch 26 sends a positioning signal to the system board, the asynchronous motor 17 is de-energized, the base plate 8 is reset, and the lower base plate 10 is reset by the rotation spring 9-4 and the spring shaft 9-6.

[0132] 19. Spreading the warp: The proximity electromagnetic switch 26 detects that the warp 8 has reached the upper stop point, and at the same time controls the even-numbered warp 6-1 to be energized by the traction electromagnet 2 6-5, spreading the warp.

[0133] 20. Passing through the coarse weft: The proximity electromagnetic switch 26 simultaneously controls the micro motor 14-6 to rotate forward and energize, driving the right shuttle magazine 14-1 and the left shuttle magazine 14 to rotate upward synchronously by 90°, reaching the supply and receiving positions respectively. The proximity electromagnetic switch 26-4 controls the micro motor 14-6 to stop rotating, and the arrow shaft motor 15-7 and the shuttle suction coil 15-3 are energized. The arrow shaft 15-1 passes through the right shuttle magazine 14-1, between the front and rear warp threads, and reaches the left shuttle magazine 14. The shuttle suction coil 15-3 attracts the coarse weft shuttle box. The Hall effect proximity electromagnetic switch 26-2 controls the arrow shaft motor 15-7 to reverse, and the Hall effect proximity electromagnetic switch 36-3 controls the arrow shaft motor 15-7 and the shuttle coil 15-3 to de-energize. The coarse weft shuttle box is stored in the right shuttle magazine 14-1, the arrow shaft 15-1 is reset, the coarse weft thread is passed through, the Hall effect proximity electromagnetic switch 36-3 controls the micro motor 14-6 to reverse, and the proximity electromagnetic switch 126-12 controls the micro motor 14-6 to stop. The two pairs of shuttle magazines are then idle in a longitudinal horizontal state.

[0134] 21. Warp Reset and Compaction: The proximity electromagnetic switch 26-12 simultaneously de-energizes the traction electromagnet 6-4 and starts the asynchronous motor 17, resetting the warp. The warp 8 descends to compact the coarse weft yarn and reset. The brake electromagnet 36 on the winding and storage shaft 35 is controlled by the proximity electromagnetic switch 26-1 installed at the lower stop of the warp 8. When the warp 8 reaches the lower stop, it momentarily releases and brakes. When the proximity electromagnetic switch 26 detects that the warp 8 has reached the upper stop, it controls the asynchronous motor 17 to stop.

[0135] 22. Front-to-back diameter conversion: The proximity electromagnetic switch 26 simultaneously controls the traction electromagnet 6-4 of the odd-numbered kite 6 to be energized, with the odd-numbered meridian 24-14 in front, thus completing the front-to-back diameter conversion.

[0136] Tip 3: Odd-numbered meridians come first.

[0137] 23. Passing through the fine weft yarn: The proximity electromagnetic switch 26 simultaneously controls the micro motor 14-6 to reverse and energize, driving the left shuttle holder 14-9 and the right shuttle holder 14-10 to rotate synchronously upwards by 90°, reaching the supply and receiving positions respectively. The proximity electromagnetic switch 26-4 then controls the micro motor 14-6 to stop, energizing the arrow shaft motor 15-7 and the shuttle suction coil 15-3. The arrow shaft 15-1 passes through the right shuttle holder 14-10 between the front and rear warp yarns, reaching the left shuttle holder 14-9. The shuttle suction coil 15-3 then attracts the fine weft yarn box. Hall effect proximity electromagnetic switch 13 26-13 controls the arrow shaft motor 15-7 to reverse, Hall effect proximity electromagnetic switch 14 26-14 controls the shuttle coil 15-3 and the arrow shaft motor 15-7 to be de-energized, the fine weft shuttle box is stored into the right shuttle magazine 14-10, the arrow shaft 15-1 is reset, the fine weft thread is passed through, Hall effect proximity electromagnetic switch 14 26-14 controls the micro motor 14-6 to rotate forward, proximity electromagnetic switch 12 26-12 controls the micro motor 14-6 to stop, and the two pairs of shuttle magazines are idle in a longitudinal horizontal state.

[0138] 24. Kite Reset and Compaction: The proximity electromagnetic switch 26-12 simultaneously de-energizes the traction electromagnet 26-5, starts the asynchronous motor 17, and resets the kite, causing the roller 8 to descend and compact the fine weft thread before resetting. The brake electromagnet 36 on the winding and storage shaft 35 is controlled by the proximity electromagnetic switch 26-1 installed at the lower stop point of the roller 8. When the roller 8 reaches the lower stop point, it momentarily releases and then brakes. When the proximity electromagnetic switch 26 detects that the roller 8 has reached the upper stop point, it controls the asynchronous motor 17 to stop.

[0139] 25. The proximity electromagnetic switch 26 continues to control the subsequent operation of spreading the warp needles...

[0140] In summary, the following process is executed sequentially: Open the warp needle, reset the warp thread to thread segment 9-7, retract the needle and tamp, open the warp thread to pass the thicker weft thread, reset and tamp the warp thread, change the front and rear diameters to pass the thinner weft thread, reset and tamp the warp thread. Open the warp needle… repeat the cycle. Additionally, it should be noted that after the hook reaches the yarn position, i.e., when the proximity electromagnetic switch 7 26-7 outputs a signal, the system must separately identify whether the proximity electromagnetic switches 8 26-8 and 9 26-9, and whether the feed plate 22-1 has reached the yarn supply position. Normally, the hook reaches the yarn position earlier than the feed plate 22-1 reaches the yarn supply position. Therefore, in the factory mode setting, sufficient arrival time must be allowed for the feed plate 22-1; an alarm will sound and the machine will stop if the timeout is exceeded. Additionally, it should be noted in the above description that after the feeding plate 22-1 reaches the wire feeding position, if the odd-numbered meridian is in front, the feeding plate 22-1, driven by the stepper motor 24-13, drags the main body 23-3 to continue moving to the left, and the wire outlet end 24-4 of the guide tube is pulled towards the original position to the upper right by the traction spring 24-6. If the even-numbered meridian is in front, the feeding plate 22-1 does not drag the main body 23-3 to move, and the guide tube 24-3 is pulled towards the upper left by the traction electromagnet 24-10. The second paragraph of item 4 in Tip 1, "Odd-numbered meridians in front," has already prepared for the following Tip 2, "Even-numbered meridians in front," to avoid misunderstanding. The second paragraph of item 16 in Tip 2 is also described in this way.

[0141] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
