Description

Technical Field

[0001] This invention relates to the field of warp threading machine design technology, and particularly to a warp frame for an automatic warp threading machine. Background Technology

[0002] Automatic warping machines are core automated equipment in the front-end of textile weaving. They are mainly used to sequentially thread warp yarns into stop warp pieces, heddles, and reeds according to process requirements, replacing the traditional manual warping process. This significantly improves warping efficiency and accuracy, and is especially suitable for the production of high-count, high-density fabrics and special roving fabrics. It can effectively reduce the intensity of manual labor, avoid the problems of incorrect or missed warping during manual warping, and ensure the smooth operation of subsequent weaving processes.

[0003] Its core structure can be divided into the following 5 main parts:

[0004] 1. Warp yarn combing and feeding module

[0005] Also known as a "warp frame", it is used to support and tension the entire warp, combing the messy yarn into parallel and uniform yarn sheets, providing a regular yarn supply for the subsequent yarn separation process. Some modified models can be compatible with 1000D-3000D high denier coarse yarns.

[0006] 2. Yarn splitting execution module

[0007] The core action unit that accurately picks up a single warp yarn by using components such as the rapier belt, rapier belt guide rail, and rapier belt hook to separate the target yarn from the entire yarn sheet is the core action unit that ensures accurate single yarn picking. After being upgraded and widened, it can be adapted to thick yarns and avoid yarn breakage and slippage problems.

[0008] 3. Insertion of stop-warp yarns / heddles into the module

[0009] The separated warp yarns are sequentially threaded into the designated holes of the stop warp and heddle. This module can adjust the threading order according to different fabric processes and supports the adaptation and switching of stop warp and heddle of different specifications.

[0010] 4. Insert the reed into the module.

[0011] After completing the final step of threading the reed, the warp yarns that have already passed through the stop warp and heddles are precisely threaded into the gaps between the teeth of the reed, strictly corresponding to the number of yarns threaded into each reed as required by the process.

[0012] 5. Control and Auxiliary Material Receiving Module

[0013] It includes the motion control system of the whole machine, detection and error correction sensors, and finished warp yarn winding station. It can automatically identify mis-threading and missing threading problems and alarm, and neatly wind up the warp yarns that have completed the entire process of warping, directly connecting to the subsequent production process of the loom.

[0014] Currently, Chinese patent CN219637456U, published on September 5, 2023, discloses an automatic control device for a yarn frame cart. The device includes a yarn frame cart with upright mechanisms on both sides of its bottom. It also includes a differential mechanism for steering and moving the yarn frame cart, a lifting mechanism for controlling the raising and lowering of the differential, and an electrical system. The differential mechanism and lifting mechanism are respectively located on one side of the upright mechanisms on both sides of the yarn frame cart. The lifting mechanism is positioned above the horizontal plate of the upright mechanism, and the differential mechanism is positioned below the horizontal plate. The lower end of the lifting shaft of the lifting mechanism is connected to the differential mechanism. The electrical system is electrically connected to the encoder in the lifting mechanism and the servo motor of the differential mechanism. This automatic control device can automatically control the movement and steering of the yarn frame cart, reducing labor intensity, shortening transportation time, and improving the operating efficiency of the automatic warping machine.

[0015] In existing technology, the yarn frame is a warp frame that supports and organizes the yarn, combing the messy yarn into parallel and uniform yarn sheets, providing a regular yarn supply for the subsequent yarn separation process. However, when the yarn is threaded onto this type of yarn frame, the yarn is in a vertical position. During the subsequent processing, the entire yarn is vertically distributed. When the steel comb is combing the yarn layer, it is impossible to lay all the yarn flat on the same operating plane at once. It is necessary to repeatedly move the combing tool up and down to check for misaligned yarns. The yarn sorting time will increase by more than 40% compared to horizontal yarn sorting, and it is also easy to miss some yarn segments. Summary of the Invention

[0016] The purpose of this invention is to provide a warp frame for an automatic warp threading machine that can switch the entire yarn between vertical and horizontal positions.

[0017] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a warp frame of an automatic warp threading machine, comprising a gantry and a yarn roller located on one side of the gantry for unwinding the wound yarn, upright plates provided on both sides of the gantry, a flipping frame provided between the two upright plates, a guide roller for the yarn to pass through provided on one side of the flipping frame, a brush roller provided on the side of the flipping frame away from the guide roller, brush strips for the yarn to be embedded on the periphery of the brush roller, and an adjustment component provided on the gantry for driving the flipping frame to flip to different angles.

[0018] By adopting the above technical solution, when the yarn needs to be combed on the gantry, the adjusting component flips the rotating frame to a horizontal position. The yarn in the yarn roller passes through the guide roller and enters the brush roller, where it is embedded between the bristles of the brush strip, thus positioning the yarn. Then, the yarn laid flat on the rotating frame can be combed. When combing is completed and the yarn separation module is needed for the next step, the adjusting component flips the rotating frame to a vertical position again, and the yarn can then enter the yarn separation module for separation. Finally, the entire yarn can be switched between vertical and horizontal positions, facilitating convenient and efficient combing of the yarn in the horizontal position.

[0019] A further embodiment of the present invention is provided that the adjustment assembly includes an elongated hole formed on the upright plate and extending in a vertical direction, a guide wheel rotatably connected to the end of the tilting frame located on one side of the guide roller and embedded in the elongated hole, a swing arm with one end hinged to the gantry and the other end hinged to the middle side of the tilting frame, a return spring with its lower end connected to the swing arm and its upper end connected to the upright plate, and a drive member disposed on the side of the gantry and used to drive the swing arm to swing downward.

[0020] By adopting the above technical solution, the driving component drives the swing arm to swing downward, and the return spring is stretched. Subsequently, the swing arm drives the tilting frame to swing downward. At the same time, since the guide wheel at the end of the tilting frame is embedded in the vertical elongated hole, the tilting frame can tilt towards the horizontal position, thereby completing the adjustment of the tilting frame's horizontal position. When the driving component is released, the return spring can elastically recover. At this time, the return spring can drive the swing arm to swing upward. At the same time, since the guide wheel at the end of the tilting frame is embedded in the vertical elongated hole, and the swing arm and the tilting frame are V-shaped, under the traction of the return spring, the tilting frame can tilt towards the vertical position, thereby completing the adjustment of the tilting frame's vertical position.

[0021] A further configuration of the present invention is as follows: the driving component includes a swing rod disposed on the side wall of the swing arm, a handle rod movably connected at one end to the side wall of the gantry and used to press down on the swing rod, a column disposed on the lower side of the gantry, and a first positioning buckle disposed on the column and into which the handle rod is embedded.

[0022] By adopting the above technical solution, the operator can press down the swing rod with the handle rod, thereby moving the swing rod downwards until the tilting frame is tilted to a horizontal position. Then the handle rod swings horizontally and can be embedded in the first positioning buckle, thereby completing the positioning of the handle rod and finally completing the positioning of the tilting frame in the horizontal position.

[0023] A further feature of the present invention is that: an opening groove is provided at the end of the handle rod, a central shaft is provided in the opening groove, and a shaft arm is provided on the side wall of the gantry, with one end rotatably connected to the side wall of the gantry and the other end through which the central shaft passes.

[0024] By adopting the above technical solution, the handle lever utilizes the central shaft of the open slot, one end of the shaft arm is rotatably connected to the side wall of the gantry, and the other end allows the central shaft to pass through, so that the up-down swinging and left-right swinging operations of the handle lever can be realized at this time.

[0025] The present invention is further configured as follows: a connection table is provided on the turnover frame and on one side of the brush roller, two elastic clamping plates are provided on the upper side of the connection table, a clamping head portion is provided on the side edge of each elastic clamping plate, an elastic clamping rail for pressing the finished sorted yarn onto the elastic clamping plates is provided on the connection table, the cross section of the elastic clamping rail is in a "冂" shape, and clamping protruding strips that are clamped with the clamping head portions are provided on both inner sides of the elastic clamping rail.

[0026] By adopting the above technical solution, when the yarn is transported to the position of the brush roller and carded, the yarn is pressed onto the elastic clamping plates by the elastic clamping rail, wherein the clamping protruding strips of the elastic clamping rail are clamped with the clamping head portions of the elastic clamping plates, so that the position of the yarn can be positioned at this time.

[0027] The present invention is further configured as follows: a moving base is further provided on the lower side of the turnover frame, a plurality of self-locking casters are provided on the lower side of the moving base, a storage box is provided on the upper side of the moving base, and the bottom inside the storage box contains talcum powder to be sprinkled on the yarn.

[0028] By adopting the above technical solution, when the drawing-in machine is in operation, the yarn needs to pass through the droppers, heddle eyes and reed dents of the steel reed at high speed in sequence; severe friction will occur between the yarns, and between the yarns and metal parts such as heddles / droppers; the talcum powder has fine particles and a layered silicate structure, the particles are easy to slide between each other, which can form a lubricating film on the yarn surface, significantly reduce the friction coefficient, and make the yarn pass through each yarn guide component smoothly; after the yarn on the turnover frame is carded, the moving base is moved to the lower side of the turnover frame, and then the talcum powder in the storage box is sprinkled on the yarn, so as to complete the addition of a layer of talcum powder on the yarn surface.

[0029] The present invention is further configured as follows: a second positioning buckle is further provided on the upright post and on the lower side of the first positioning buckle. When the handle lever is embedded in the second positioning buckle, the turnover frame moves downward and the yarn is attached to the storage box; the moving base is further provided with a sprinkling assembly for uniformly sprinkling the talcum powder in the storage box onto the yarn.

[0030] By adopting the above technical solution, after the moving base is moved to the lower side of the turnover frame, the handle lever is further pressed down, so that the turnover frame moves downward and the yarn is attached to the storage box, and the handle lever is embedded in the second positioning buckle, then the talcum powder in the storage box can be uniformly sprinkled on the yarn by using the sprinkling assembly.

[0031] A further configuration of the present invention is as follows: the spreading assembly includes a frame plate that slides vertically and horizontally within a storage box, an elastic cotton net disposed within the frame plate, an elongated groove at the end of the storage box, a connecting rod disposed at the end of the frame plate and passing through the elongated groove, a connecting plate disposed at the end of the connecting rod, a fixed box disposed at the end of the movable seat, a rack that slides vertically and horizontally within the fixed box and extends beyond the fixed box to receive the connecting plate, a drive gear movably connected within the fixed box and meshing with the rack, an elongated opening at the side of the fixed box, a drive arm whose one end is fixed to the drive gear and whose other end extends beyond the elongated opening, a locking arm whose lower end is hinged within the fixed box, a positioning tooth disposed at the upper end of the locking arm and embedded within the rack, an unlocking arm whose one end is connected to the lower end of the locking arm and whose other end extends beyond the elongated opening, and a connecting spring whose one end is connected to the unlocking arm and whose other end is connected to the bottom wall of the fixed box.

[0032] By adopting the above technical solution, before the talcum powder is applied, the frame plate is located at the bottom of the storage box under its own weight, at which time the elastic cotton net is embedded in the talcum powder. When it is time to apply the talcum powder, the drive arm moves back and forth and swings up and down to drive the drive gear to move back and forth and rotate up and down. When the drive gear moves forward and meshes with the rack, the drive gear rotates upward, which in turn drives the rack to move upward. At the same time, the positioning teeth of the locking arm are embedded in the rack, thereby positioning the height of the rack. Then the drive gear moves backward and disengages from the rack, and the drive gear rotates downward to reset. The previous actions are repeated, thus driving the rack to move upward step by step. At this time, the upward movement of the rack drives the connecting plate and the frame plate to move upward, thereby moving the elastic cotton net to the position to adhere to the yarn. At this time, the talcum powder on the surface of the elastic cotton net can be attached to the surface of the yarn.

[0033] A further configuration of the present invention includes: a gear shaft at the center of the drive gear; an oblong hole for the gear shaft to pass through on the side wall of the fixed box; a rubber protrusion on the inner wall of the oblong hole; a bracket on the outer wall of the fixed box at the position of the oblong hole; a drive gear rotatably connected to the bracket; an extension shaft fixed at the center of the drive gear; a mating interface inside the extension shaft; a mating plate for embedding in the mating interface at the end of the gear shaft; a connecting shaft rotatably connecting the two fixed boxes; a driven gear meshing with the drive gear at the end of the connecting shaft; multiple winding wheels on the connecting shaft; a connecting rope with one end connected to the winding wheel and the other end passing through the storage box and connected to the elastic cotton net on the winding wheel; a mounting arm for rotatably connecting the connecting shaft on the lower side of the storage box; and a return torsion spring with one end connected to the mounting arm and the other end connected to the connecting shaft sleeved on the connecting shaft.

[0034] By adopting the above technical solution, when the elastic cotton net is moved up to the position of the yarn under the drive of the rack and pinion, the drive arm drives the drive gear and the gear shaft to move backward along the waist-shaped hole and past the rubber protrusion. The drive arm swings so that the mating plate of the gear shaft is embedded in the mating interface of the extension shaft. Then, the drive arm rotates the gear shaft, which drives the extension shaft and the drive gear to rotate through the mating plate. The drive gear drives the connecting shaft to rotate through the driven gear. Then, the connecting shaft drives multiple take-up wheels to take up the connecting rope, and the return torsion spring undergoes elastic torsion. At this time, the connecting rope pulls down the elastic cotton net, causing the elastic cotton net to elastically indent. Then, the drive arm pushes the mating plate out of the mating interface, and the return torsion spring elastically recovers. The return torsion spring immediately drives the connecting shaft to rotate in the opposite direction to reset. At the same time, the take-up wheels immediately rotate in the opposite direction to unwind the connecting rope. At this time, after the elastic cotton net elastically recovers and bounces upward, the talcum powder attached to the surface of the elastic cotton net can be quickly sprinkled and attached to the surface of the yarn above. Finally, the efficient and uniform sprinkling of talcum powder on the entire yarn surface can be achieved.

[0035] A further provision of the present invention is that a first push rod is fixed between the ends of the two drive arms, and a second push rod is fixed between the ends of the two unlocking arms.

[0036] By adopting the above technical solution, the first push rod can simultaneously drive the drive arms on both sides to swing upward, while the second push rod can simultaneously press down the unlocking arm. After the unlocking arm is pressed down, the positioning tooth can be disengaged from the rack, and then the rack can descend and reset under its own gravity.

[0037] The beneficial effects of this invention are as follows: When the yarn needs to be combed on the gantry, the adjusting component flips the rotating frame to a horizontal position. The yarn in the yarn roller passes through the guide roller and enters the brush roller, where it is embedded between the bristles of the brush strip, thus positioning the yarn. Then, the yarn laid flat on the rotating frame can be combed. When combing is completed and the yarn needs to be separated using the next yarn separation execution module, the adjusting component flips the rotating frame to a vertical position again, and the yarn can then enter the yarn separation execution module for separation. Finally, the entire yarn can be switched between vertical and horizontal positions, facilitating convenient and efficient combing of the yarn in the horizontal position. Attached Figure Description

[0052] With reference to Figure 1 , Figure 3 , the gantry 1 is provided with an adjusting assembly 4 for driving the turnover frame 3 to turn over to different angles. The adjusting assembly 4 comprises a long hole 41, a guide wheel 42, a swing arm 43, a return spring 44 and a driving member 45, wherein the long hole 41 is opened on the vertical plate 11 and extends in the vertical direction, the guide wheel 42 is rotatably connected to the end of the turnover frame 3 on the side of the guide roller 31 and embedded in the long hole 41, one end of the swing arm 43 is hinged to the gantry 1 and the other end is hinged to the middle side of the turnover frame 3, and the lower end of the return spring 44 is connected with the swing arm 43 and the upper end is connected with the vertical plate 11.

[0053] With reference to Figure 3 , Figure 4 , the driving member 45 is arranged at the side of the gantry 1 and is used for driving the swing arm 43 to swing downward. The driving member 45 comprises a swing rod 451 fixed on the side wall of the swing arm 43, a handle rod 452 with one end movably connected to the side wall of the gantry 1 and used for pressing down on the swing rod 451, a stand column 453 fixed on the lower side of the gantry 1, and a first positioning buckle 454 integrally arranged on the stand column 453 and for the handle rod 452 to be embedded therein; wherein an open slot 4521 is opened at the end of the handle rod 452, a central shaft 4522 is fixed in the open slot 4521, and a shaft arm 4523 with one end rotatably connected to the side wall of the gantry 1 and the other end for the central shaft 4522 to pass through is arranged on the side wall of the gantry 1, so that the handle rod 452 can swing up and down as well as left and right.

[0054] Working principle: When the yarn needs to be combed on the gantry 1, the adjusting assembly 4 is used to turn the turnover frame 3 to a horizontal position (referring to Figure 1The yarn in yarn roller 2 passes through guide roller 31 and enters brush roller 32, where it is embedded between the bristles of brush strip 321, thus positioning the yarn. Then, the yarn laid flat on the flipping frame 3 can be combed. When combing is complete and the next step of yarn separation is needed, the flipping frame 3 is flipped back to a vertical position using adjusting component 4 (see reference). Figure 5 Then the yarn can enter the yarn separating module for yarn separating; finally, the entire yarn can be switched between vertical and horizontal positions, making it convenient and efficient to comb the yarn in the horizontal position;

[0055] The process involves pressing down the handle 452, which causes the swing arm 43 to swing downwards, stretching the return spring 44. The swing arm 43 then causes the tilting frame 3 to swing downwards. Simultaneously, because the guide wheel 42 at the end of the tilting frame 3 is embedded in the vertical elongated hole 41, the tilting frame 3 can tilt towards a horizontal position, thus adjusting its horizontal position. Simultaneously, the handle 452 swings horizontally, embedding itself in the first positioning buckle 454, thus positioning the handle 452. Finally, the tilting frame 3 is positioned horizontally. When the handle 452 is removed from the first positioning buckle 454, the return spring 44 elastically recovers, causing the swing arm 43 to swing upwards. Again, because the guide wheel 42 at the end of the tilting frame 3 is embedded in the vertical elongated hole 41, and the swing arm 43 and the tilting frame 3 form a V-shape, the tilting frame 3 can tilt towards a vertical position under the traction of the return spring 44, thus adjusting its vertical position.

When the reset torsion spring 73 is in the natural state, the interface 6623 rotates to the horizontal position to facilitate the next docking of the docking plate 6811. At the same time, when the frame plate 61 moves up to the top of the storage box 52, the connecting rope 721 is in a taut state, and when the frame plate 61 moves down to the bottom of the storage box 52, the connecting rope 721 is in a slack state.

[0059] Principle: When the warping machine is working, the yarn needs to pass through the stop warp, heddle eye and reed teeth at high speed in sequence; there will be fierce friction between the yarns and between the yarns and the metal parts such as heddle / stop warp; the talcum powder particles are fine and have a layered silicate structure, and the particles can slide easily between each other, forming a lubricating film on the yarn surface, which significantly reduces the coefficient of friction and allows the yarn to pass smoothly through each yarn guiding component; after the yarn on the turning frame 3 has been combed, the moving seat 5 is moved to the underside of the turning frame 3, and then the talcum powder in the storage box 52 is sprinkled on the yarn, thus completing the addition of a layer of talcum powder on the yarn surface;

[0060] When the movable seat 5 moves to the underside of the flipping frame 3, the handle rod 452 is pressed down further, causing the flipping frame 3 to move downwards and the yarn to adhere to the storage box 52. The handle rod 452 is then embedded in the second positioning buckle 4531. Subsequently, the talcum powder in the storage box 52 can be evenly spread on the yarn using the spreading component 6. Before spreading the talcum powder, the frame plate 61 is located at the bottom of the storage box 52 under its own weight, at which time the elastic cotton net 62 is embedded in the talcum powder. When it is necessary to spread the talcum powder, the drive arm 601 is used to move back and forth and swing up and down to drive the drive gear 68 to move back and forth. The drive gear 68 moves forward and engages with the rack 67, then rotates upward, which in turn drives the rack 67 to move upward. At the same time, the positioning teeth 603 of the locking arm 602 are embedded in the rack 67, thereby positioning the height of the rack 67. Then the drive gear 68 moves backward and disengages from the rack 67, and rotates downward to reset. The previous actions are repeated, thus driving the rack 67 to move upward step by step. At this time, the upward movement of the rack 67 can drive the connecting plate 65 and the frame plate 61 to move upward, thereby causing the elastic cotton web 62 to move upward to the position where it is in contact with the yarn.

[0061] Simultaneously, when the elastic cotton web 62 moves upward to the position of the yarn under the drive of the rack 67, the drive arm 601 drives the drive gear 68 and the gear shaft 681 to move backward along the waist-shaped hole 661 and past the rubber protrusion 6611. The drive arm 601 swings, so that the mating plate 6811 of the gear shaft 681 is embedded in the mating interface 6623 of the extension shaft 6622. Then, by rotating the gear shaft 681 with the drive arm 601, the gear shaft 681 can drive the extension shaft 6622 and the drive gear 6621 to rotate through the mating plate 6811. The drive gear 6621 can then drive the connecting shaft 7 to rotate through the driven gear 71. Then, the connecting shaft 7 can drive multiple winding wheels 72 to wind up the connecting rope 721, and the return torsion spring 73 will undergo elastic torsion. At this time, the connecting rope 721 can pull down the elastic cotton web 62, so that the elastic cotton web 62 can... The elastic indentation is generated; then the drive arm 601 pushes the docking plate 6811 out of the docking interface 6623, and the reset torsion spring 73 can elastically recover. The reset torsion spring 73 can immediately drive the connecting shaft 7 to rotate in the opposite direction to reset. At the same time, the winding wheel 72 immediately rotates in the opposite direction to unwind the connecting rope 721. At this time, the elastic cotton net 62 elastically recovers and bounces upward and hits the yarn. The talcum powder attached to the surface of the elastic cotton net 62 can be quickly spread and lifted upward and attached to the surface of the yarn above. At the same time, due to the elastic recovery force of the elastic cotton net 62, the talcum powder is driven to impact upward. Therefore, some of the talcum powder crosses the gap between the yarns and falls back, and can then be attached to the surface of the yarn. At this time, the talcum powder can be stably spread on the upper and lower surfaces of the yarn, and finally, the talcum powder can be efficiently and evenly spread on the entire surface of the yarn.
