Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and more particularly to an air-jet loom. Background Technology

[0002] Air-jet textile machines are high-efficiency textile equipment that uses compressed airflow to pull weft yarns through the shed to complete weaving. They are widely used in the production of plain weave, textured weave, and fine, high-density fabrics. The airflow generates frictional traction on the weft yarn, pulling it across the shed to achieve weft insertion. Airflow weft insertion is characterized by high speed and high tension, but it requires high-quality raw yarn and semi-finished products. Because air-jet textile machines weave at high speeds and the fabric rolls up quickly, the frequency of changing the rolls is relatively high; however, the time required to change the rolls is also relatively long.

[0003] Patent application number 202322021099.0 discloses an air-jet loom in which the connecting parts on the fixed part are fixed and the connecting parts on the movable part are movable. The fabric roll can be locked between the two connecting parts and fixed by the connecting parts on the movable part. When installing and removing the fabric roll, only the connecting parts on the movable part need to be moved, which is convenient and efficient.

[0004] The air-jet loom in the aforementioned patent has the following shortcomings: Although the device reduces the difficulty of disassembling and installing the fabric roll, in actual operation, it is still necessary to stop the entire device and then follow the disassembly and installation steps, so the efficiency of replacing the fabric roll is still relatively low. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and to propose an air-jet loom.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An air-jet loom includes a support frame structure and a loom take-up roller, the support frame structure being connected to the air-jet loom; The loom winding rollers are configured as multiple rollers, which are equidistantly and movable on the support frame structure, and are used to weave and wind up the fabric in sequence. The main body of the support frame structure is configured as a load-bearing support frame. An installation cylinder is rotatably installed inside the load-bearing support frame. Multiple sets of connecting frame arms are fixedly connected to the outer wall of the installation cylinder. The loom winding roller is rotatably connected to the connecting frame arms. One end of the support frame is fixedly equipped with a mounting and positioning frame, and a servo motor is movably mounted on the top of the mounting and positioning frame. The output shaft of the servo motor is equipped with a transmission connecting sleeve, and the transmission connecting sleeve is fixedly connected to the loom's winding roller.

[0007] As a preferred embodiment of the present invention: a mounting plate is fixedly mounted on the top of the mounting positioning frame, and multiple sliding bearing rollers are rotatably mounted on the top of both sides of the mounting plate, and a mounting through groove is provided in the middle of the upper surface of the mounting plate.

[0008] Based on the aforementioned scheme: a transmission slider is slidably installed inside the mounting slot, a sliding mounting plate is fixedly connected to the top of the transmission slider, a motor base is fixedly installed on the upper surface of the sliding mounting plate, and the servo motor is fixedly installed on the top of the motor base.

[0009] Based on the aforementioned scheme: a telescopic cylinder is fixedly installed on the upper part of the front end of the mounting plate, and the telescopic end of the telescopic cylinder extends into the sliding mounting through groove and is fixedly connected to the transmission slider.

[0010] Based on the aforementioned scheme: a limiting slide rod is fixedly installed at the lower part of the mounting slot, the limiting slide rod is slidably connected to the transmission slider, and a stabilizing insert rod is fixedly connected to the bottom of the tail end of the transmission slider.

[0011] As a preferred embodiment of the present invention: a positioning connecting frame is fixedly installed on one side of the bearing support frame, and a positioning impact rod is fixedly installed on the top of one end of the positioning connecting frame, with one end face of the positioning impact rod and one end face of the loom winding roller in the same vertical plane.

[0012] As a preferred embodiment of the present invention: a bearing shaft is fixedly installed inside the mounting cylinder, both ends of the bearing shaft passing through the bearing support frame and extending outward, and a cross control handle is fixedly installed at one of the extended ends.

[0013] As a preferred embodiment of the present invention: a long rod insertion hole is provided in the middle of the connecting frame arm, a limiting long rod is inserted into the long rod insertion hole, both ends of the limiting long rod penetrate the bearing support frame, and multiple connecting frame arms at one end of the mounting drum are provided with rod fitting grooves.

[0014] As a preferred embodiment of the present invention: a front-end connecting frame is fixedly installed on one side of the bearing support frame, and an installation shaft is rotatably installed on the upper part of the front-end connecting frame, with a guide roller sleeved on the outer wall of the installation shaft.

[0015] Based on the aforementioned scheme: a fixed mounting bracket is fixedly installed on the lower part of the front connecting frame, and a lifting cylinder and multiple guide slide rods are installed inside the fixed mounting bracket. A fixed top arm is installed together on the top of the telescopic end of the lifting cylinder and the top of the guide slide rods.

[0016] The beneficial effects of this invention are as follows: This application adopts a design with multiple loom rolls equidistantly and movable, and the cyclic switching of rolls is achieved by rotating the mounting drum. After the current roll has finished winding, there is no need to stop the air-jet loom for a long time. The position of the roll is adjusted by the servo motor and telescopic cylinder controlled by the controller, so that the next idle roll can quickly take over the winding task. This continuous operation mode of "winding and changing at the same time" completely avoids the long downtime caused by changing rolls in traditional looms, effectively shortens the downtime, and improves the continuous operation efficiency of the loom.

[0017] The telescopic cylinder's extension and retraction are synchronously controlled by the controller, which can quickly push the sliding mounting plate to move the transmission slider, allowing the multi-faceted insert of the fabric roll to quickly separate or engage with the transmission connecting sleeve, reducing the time cost of manual adjustment; the positioning bumper can determine the position of one end of the fabric roll, preventing misalignment of multiple fabric rolls; the cooperation between the stabilizing insert and the insert groove further ensures the stability of the fabric roll installation and prevents deviation during the winding process.

[0018] Its multi-roller design and automated control enable it to adapt to the winding needs of fabrics of different thicknesses and materials; by adjusting the speed of the servo motor and the stroke of the telescopic cylinder, it can achieve precise winding of fabrics of different lengths; the quick-change design of the roll rollers also enables the device to meet the production needs of multiple varieties and small batches, improving the versatility of the equipment.

[0026] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0027] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] A jet loom, such as Figures 1 to 6 As shown, the device includes a support frame structure and a loom winding roller 8. The support frame structure is connected to the air-jet loom. Multiple loom winding rollers 8 are installed equidistantly on the support frame structure and are used sequentially for weaving and winding. This effectively shortens the downtime of the air-jet loom. When the current loom winding roller 8 is weaving and winding, it does not affect the disassembly and reinstallation of the previous loom winding roller 8, thus significantly improving the working efficiency of the air-jet loom and increasing the winding speed of the device for weaving.

[0029] Example 1: The main body of the support frame structure is a load-bearing support frame, which includes a load-bearing support frame 1 and a load-bearing support frame 2. Both are set in an "A" shape, and two fixed crossbars 3 are welded to the lower part between them to improve the installation stability of the load-bearing support frame. Rubber pads are installed at the bottom of both to play the role of shock absorption, anti-slip and anti-displacement.

[0030] A bearing shaft 4 is rotatably mounted on the top between the bearing support frame 1 and the bearing support frame 2 via a bearing. Both ends of the bearing shaft 4 pass through the bearing support frame and extend outward. An installation cylinder 5 is fixedly sleeved on the outer wall of the bearing shaft 4. Multiple sets of connecting frame arms are fixedly connected to the outer wall of the installation cylinder 5.

[0031] Each set of connecting arms includes connecting arm 1 (6) and connecting arm 2 (7). Connecting arm 1 (6) is close to bearing support frame 1 (1), and connecting arm 2 (7) is close to bearing support frame 2 (2). Both connecting arm 1 (6) and connecting arm 2 (7) have long rod insertion holes 32 in their middle parts. Connecting arm 1 (6) also has a rod mating groove 31 in its middle part. The rod mating groove 31 is located between the long rod insertion hole 32 and the mounting drum 5.

[0032] The ends of connecting arm 1 (6) and connecting arm 2 (7) away from the installation drum 5 are set as separate units, that is, the ends are fixed with clamps by bolts, and the clamps are fitted with bearings. The bearings are sleeved on the end of the loom winding roller 8, so that the loom winding roller 8 can rotate on the connecting arm, but will not have relative displacement with the connecting arm.

[0033] A mounting positioning frame 9 is fixedly installed on the upper part of the side of the support frame 1 away from the mounting drum 5. A mounting plate 17 is fixedly installed on the top of the mounting positioning frame 9. Grooves are opened on the top of both sides of the mounting plate 17. Multiple positioning mounting pins 18 are installed at equal intervals on the side walls of the grooves. A sliding bearing roller 19 is rotatably installed on the outer wall of the positioning mounting pins 18.

[0034] The main body of the mounting positioning frame 9 is a U-shaped frame. The U-shaped frame is fixedly installed on the upper part of the load-bearing support frame 1 by bolts. The upper parts of the two arms of the U-shaped frame are bent away from the connecting frame arm 6. An inclined support plate is welded between the bottom end of the bent section and the bottom end of the U-shaped frame to improve the load-bearing capacity of the mounting positioning frame 9. The mounting plate 17 is fixedly installed on the top of the two bent sections by bolts.

[0035] A mounting slot 21 is provided in the middle of the upper surface of the mounting plate 17. A transmission slider 22 is slidably installed inside the mounting slot 21. A sliding mounting plate 23 is fixedly connected to the top of the transmission slider 22. The lower surface of the sliding mounting plate 23 is in contact with the outer wall of the sliding bearing roller 19 to improve the smoothness of the sliding of the sliding mounting plate 23.

[0036] A motor base 24 is fixedly mounted on the upper surface of the sliding mounting plate 23. A servo motor 25 is fixedly mounted on the top of the motor base 24. A transmission connecting sleeve 28 is mounted on the output shaft of the servo motor 25. The transmission connecting sleeve 28 is fixedly connected to the loom winding roller 8.

[0037] One end of the transmission connecting sleeve 28 is fixedly installed on the output shaft of the servo motor 25, and the other end is provided with a multi-faceted slot. Both ends of the loom winding roller 8 are integrally formed with multi-faceted posts, which are inserted into the multi-faceted slot. The multi-faceted posts and multi-faceted slots shown in this application are both set as regular square prisms, and the end faces of the multi-faceted posts are chamfered to facilitate quick assembly of the multi-faceted posts and multi-faceted slots.

[0038] A telescopic cylinder 20 is fixedly installed on the upper part of the front end of the mounting plate 17 (the side away from the connecting arm 6). The telescopic end of the telescopic cylinder 20 passes through the groove wall of the mounting through groove 21 and extends into the sliding mounting through groove 21 and is fixedly connected to the transmission slider 22 to drive the transmission slider 22 to slide. The telescopic cylinder 20 is selected as a lockable model. When the telescopic cylinder 20 is extended, it can be completely locked in the extended state to ensure the stability of the servo motor 25.

[0039] A limiting slide rod 29 is fixedly installed at the lower part of the mounting slot 21. The limiting slide rod 29 passes through the transmission slider 22 and is slidably connected to the transmission slider 22 through a linear bearing. The limiting slide rod 29 cooperates with the sliding bearing roller 19 to improve the sliding stability of the servo motor 25. A stabilizing insert rod 30 is fixedly connected to the bottom of the tail end of the transmission slider 22. When the multi-faceted insert is inserted into the multi-faceted slot, the stabilizing insert rod 30 is simultaneously inserted into the insert rod mating groove 31, and at this time, the two sides of the stabilizing insert rod 30 are in contact with the side walls of the insert rod mating groove 31.

[0040] A positioning connecting frame 35 is fixedly installed on one side of the support frame 1. A positioning impact rod 36 is fixedly installed on the top of one end of the positioning connecting frame 35. One end face of the positioning impact rod 36 is on the same vertical plane as one end face of the loom winding roller 8. The positioning impact rod 36 is used for positioning the loom winding roller 8 during installation, determining the position of one end of the loom winding roller 8, facilitating the installation of the loom winding roller 8, and avoiding misalignment of multiple loom winding rollers 8, which would affect the operation of the overall device.

[0041] The bearing shaft 4 has an installation groove at the extended end on one side of the bearing support frame 2, and a cross control handle 27 is provided at the end of the bearing shaft 4. One side of the cross control handle 27 is integrally formed with a mounting square column, which is inserted into the installation groove and fixed by bolts. A control connecting pin 37 is welded to one side of the support arm end (four support arms) of the cross control handle 27. A rubber connecting sleeve 38 is sleeved on the outer wall of the control connecting pin 37 to facilitate the operator to operate the bearing shaft 4 to drive the installation drum 5 to rotate.

[0042] like Figure 1 As shown, the connecting arms are set to four groups. From the direction of the servo motor 25, the four loom winding rollers 8 installed on the four groups of connecting arms are number one, number two, number three and number four in a clockwise direction. The number one roller is connected to the transmission connecting sleeve 28 and is used for weaving and winding of the textile machine. The position of the number two roller is used as the replacement position, that is, the loom winding roller 8 that has completed weaving and winding is removed and replaced with a new loom winding roller 8.

[0043] A fabric pressing groove 33 is provided in the middle of the outer wall of the loom winding roller 8. A fabric pressing arm 34 is engaged inside the fabric pressing groove 33. When the loom winding roller 8 is in the position of the first roller and is connected to the transmission connecting sleeve 28, the loom winding roller 8 is manually adjusted so that the fabric pressing groove 33 faces upward. Then, the fabric covering the loom winding roller 8 is pressed into the fabric pressing groove 33 by the fabric pressing arm 34. Then, the fabric is cut to complete the fabric fixing work of the first roller corresponding to the loom winding roller 8. The servo motor 25 drives the loom winding roller 8 to weave and wind up the fabric.

[0044] A limiting rod 26 is inserted into the long rod insertion hole 32 of the connecting frame arm corresponding to the No. 3 roller. Both ends of the limiting rod 26 pass through the bearing support frame and are used to fix the rotating drum 5. Together with the stabilizing rod 30, the stability of the rotating drum 5 is maintained.

[0045] This device is directly controlled by a controller, which is connected to the control system of the jet textile machine. It directly controls the output speed of the servo motor 25 and the extension and retraction state of the telescopic cylinder 20 to ensure that the loom winding roller 8 can stably perform weaving and winding.

[0046] In this embodiment, the device is first assembled as shown in the figure. The controller controls the servo motor 25 to drive the loom winding roller 8 corresponding to the first roller to wind up the fabric of the air-jet textile machine.

[0047] After the loom's winding roller 8 completes the winding of the fabric to the specified length, the jet textile machine stops, the servo motor 25 stops rotating, and the operator controls the telescopic cylinder 20 to retract via the controller, so that the transmission connecting sleeve 28 separates from the loom's winding roller 8 corresponding to the first roller.

[0048] Then remove the limit rod 26, and control the bearing shaft 4 to rotate the installation drum 5 clockwise by using the cross control handle 27, so that the loom winding roller 8 corresponding to roller 1 moves to the position of roller 2, and at the same time, the loom winding roller 8 corresponding to roller 4 moves to the position of roller 1.

[0049] Under the action of the bearing, as the loom winding roller 8 corresponding to roller number one moves to the position of roller number two, the loom winding roller 8 itself slowly unwinds, and the unwound fabric covers the loom winding roller 8 that has moved back to the position of roller number one.

[0050] After the position change of the loom winding roller 8 is completed, the limiting rod 26 is reinstalled to initially fix the mounting drum 5; then the telescopic cylinder 20 is extended by the controller, and the sliding mounting plate 23 is driven to approach the connecting arm 6 by the transmission slider 22, and the angle of the loom winding roller 8 corresponding to the first roller is adjusted at the same time so that the multi-faceted insert can be smoothly inserted into the multi-faceted slot of the transmission connecting sleeve 28; at the same time, the stabilizing insert 30 is inserted into the insert mating groove 31 of the corresponding connecting arm 6.

[0051] Then, manually adjust the position of the fabric winding roller 8 of the corresponding loom so that the pressure groove 33 of the fabric winding roller 8 faces upward and the fabric can completely cover the pressure groove 33. Then, install the pressure arm 34 inside the pressure groove 33 to fix the fabric to the fabric winding roller 8 of the loom. Next, cut the fabric near the fabric winding roller 8 of the loom to separate the wound fabric from the fabric inside the air jet loom. Then, start the servo motor 25 and the air jet loom to continue the weaving and winding work.

[0052] Finally, replace the loom winding roller 8 corresponding to roller number two. First, remove the clamps and bearings of the connecting arm corresponding to roller number two, and remove the loom winding roller 8 that is used for winding the fabric. Then, install the new loom winding roller 8, making one end of the new loom winding roller 8 fit against the positioning impact rod 36. Then, clamp the bearings with grease applied to both ends of the loom winding roller 8, and install the clamps to complete the replacement of the loom winding roller 8.

[0053] Example 2: Based on Example 1, a front connecting frame 10 (near the No. 4 roller) is fixedly installed in the middle of the side of the bearing support frame 1 and the bearing support frame 2 near the air jet loom. A mounting shaft 11 is rotatably installed on the upper part of the front connecting frame 10, and a guide roller 12 is sleeved on the outer wall of the mounting shaft 11.

[0054] A fixed mounting bracket 14 is fixedly installed on the lower part of the front connecting bracket 10. The fixed mounting bracket 14 is equipped with a lifting cylinder 15 and multiple guide slide rods 16. The guide slide rods 16 are slidably connected to the fixed mounting bracket 14 through linear bearings. A fixed top arm 13 is installed on the top of the telescopic end of the lifting cylinder 15 and the top of the guide slide rod 16. A rubber pad is bonded to the top of the fixed top arm 13 to cooperate with the guide roller 12 to press the fabric.

[0055] The lifting cylinder 15 and the telescopic cylinder 20 are synchronously connected to the high-pressure air supply system of the jet loom through a diversion valve and are directly controlled by the controller.

[0056] In this embodiment, after the jet loom and servo motor 25 stop synchronously, the controller directly starts the lifting cylinder 15. The lifting cylinder 15 extends, causing the fixed top arm 13 to cooperate with the guide roller 12 through the rubber pad to press the fabric. Then, the position of the loom winding roller 8 is changed in the manner of embodiment one to avoid excessive stretching of the warp threads of the fabric that has not been inserted during the roller position change, which could lead to warp thread breakage.

[0057] Example 3: A ratchet and a locking arm assembly is installed at the end of the bearing shaft 4. The ratchet is fixed to the bearing shaft 4, and the locking arm is rotatably connected to the bearing support frame 1 to prevent the bearing shaft 4 from rotating counterclockwise.

[0058] A brake is installed at the end of the connecting arm 7 to brake the loom winding roller 8, so as to prevent the loom winding roller 8 from rotating during the roller position change process and causing the fabric to roll out, thus ensuring the stability of the roller position change.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
