Description

Technical Field

[0001] This invention relates to the field of air-jet loom equipment technology, specifically to an air-jet loom guiding device. Background Technology

[0002] An air-jet loom is a shuttleless loom that uses a jet of air to pull the weft yarn through the shed to achieve weaving. Its working principle utilizes air as the weft-guiding medium; the compressed air jet creates frictional traction on the weft yarn, pulling it through the shed. Air-jet looms offer advantages such as high speed and high output, wide adaptability to various product types, low material consumption, and high efficiency.

[0003] For example, the utility model patent with publication number CN212925310U discloses a weft insertion structure for an air-jet loom, including a frame, a reed seat rotatably mounted on the frame, a main nozzle disposed on the reed seat, and the main nozzle including a first auxiliary nozzle and a second auxiliary nozzle. The first auxiliary nozzle is disposed on the reed seat, and the second auxiliary nozzle is rotatably disposed on the first auxiliary nozzle, with the first and second auxiliary nozzles cooperating to form the main nozzle. A locking component connected to the second auxiliary nozzle is disposed on the first auxiliary nozzle. This application completes the weft insertion process by opening the locking component, rotating the second auxiliary nozzle away from the first auxiliary nozzle, placing the weft yarn into and out of the first auxiliary nozzle, rotating the second auxiliary nozzle against the first auxiliary nozzle, and finally locking the locking component. This saves time and improves production efficiency.

[0004] Although the above-mentioned equipment can guide the textile yarn, it still requires manual operation to open and close the nozzles of the spray-painted loom and manual threading of the weft yarn, which reduces the automation level of the equipment and the convenience of guiding the weft yarn. Therefore, an air-jet loom is needed in conjunction with the guiding equipment to solve the problems mentioned above. Summary of the Invention

[0013] Preferably, the two sets of guide rollers located on the same side are connected by the transmission gear, and the center of the two sets of guide rollers is directly opposite the axis of the guide nozzle, which facilitates the subsequent rapid and accurate guidance of the weft yarn.

[0014] Preferably, the limiting gear meshes with the connecting gear ring, and the connecting gear ring meshes with two sets of guide gears, which can effectively improve the stability of the internal transmission of the subsequent equipment and improve the transmission efficiency.

[0015] Preferably, the connecting screw is adapted to the threaded sleeve, and the limiting device is threadedly slidably connected inside the guide nozzle through the adaptation of the connecting screw and the threaded sleeve, which can effectively improve the stability and accuracy of subsequent guiding displacement of the weft thread.

[0016] Preferably, the side wall of the connecting pressure plate is slidably connected to the interior of the alignment slide, and the alignment slide is slidably connected to the interior of the guide nozzle through the threaded sliding sleeve. When the weft yarn is limited, the two sets of oppositely arranged connecting pressure plates can lock the weft yarn under the threaded sliding of the micro motor and the positioning screw, thereby improving the automation level of subsequent guidance.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] The invention will be further described below with reference to the accompanying drawings.

[0033] Example 1

[0034] Please see Figure 1-8 One embodiment of the present invention provides a guide device for an air-jet loom, comprising a support base 1, wherein two sets of profile support columns 2 are provided on the upper end face of the support base 1 near the front.

[0035] Material guiding device 3 is fixedly installed on the upper end face of the two sets of profile support columns 2;

[0036] The guide device 4 is fixedly installed at the center of the upper end face of the support base 1, and two sets of support columns 7 are provided near the rear of the upper end face of the support base 1.

[0037] The alignment conduit 5 is fixedly installed on the upper end face of the two sets of supporting base columns 7, and a connecting chamfer 6 is symmetrically opened on the side end face of the alignment conduit 5.

[0038] The material guiding device 3 includes a fixed guide seat 32. Two sets of guide rollers 31 are symmetrically and rotatably engaged on the inner end face of the fixed guide seat 32. A synchronous pulley 34 is fixedly installed on one side of the guide roller 31, and a transmission gear 37 is fixedly installed on the other side of the guide roller 31. The two sets of synchronous pulleys 34 on the same side are meshed and connected by a synchronous belt 33. A motor holder 36 is provided on the side of the fixed guide seat 32 near the rear, and a servo motor 35 is provided on the side end face of the motor holder 36 opposite to the guide roller 31.

[0039] The guiding device 4 includes a guide nozzle 49 for support. The rear end face of the guide nozzle 49 is provided with a positioning groove 47 for limiting. Two sets of connecting screws 42 are rotatably engaged on the inner end face of the positioning groove 47. A guide gear 45 is provided at the center of the rear end face of the connecting screws 42. A connecting gear ring 44 is rotatably engaged on the rear end face of the guide nozzle 49 near the guide gear 45. A stepper motor 46 is provided on the rear end face of the guide nozzle 49 near the connecting gear ring 44. A limiting gear 48 is fixedly provided at the output end of the stepper motor 46. A limiting device 41 is threadedly connected to the inner end face of the guide nozzle 49 through the connecting screws 42. A spring air inlet pipe 43 for guiding air is provided on the lower end face of the guide nozzle 49.

[0040] The limiting device 41 includes a positioning slide 411. Threaded sliding sleeves 412 are symmetrically arranged on the outer end face of the positioning slide 411. Micro motors 416 are arranged at the top and bottom of the inner end face of the positioning slide 411. Positioning screws 415 are arranged at the output ends of the two sets of micro motors 416. Threaded slide 413 is threadedly connected to the inner end face of the positioning slide 411 through the positioning screws 415. A connecting pressure plate 414 is arranged at the bottom of the threaded slide 413.

[0041] The two sets of guide rollers 31 located on the same side are connected by a transmission gear 37, and the center of the two sets of guide rollers 31 is directly opposite the axis of the guide nozzle 49, which facilitates the rapid and accurate guidance of the weft yarn in the future.

[0042] The limiting gear 48 meshes with the connecting gear ring 44, and the connecting gear ring 44 meshes with two sets of guide gears 45, which can effectively improve the stability of the internal transmission of the subsequent equipment and improve the transmission efficiency.

[0043] The connecting screw 42 is adapted to the threaded sleeve 412, and the limiting device 41 is threadedly slidably connected inside the guide nozzle 49 through the adaptation of the connecting screw 42 and the threaded sleeve 412, which can effectively improve the stability and accuracy of subsequent guiding displacement of the weft thread.

[0044] The side wall of the connecting pressure plate 414 is slidably connected to the inside of the alignment slide 411, and the alignment slide 411 is slidably connected to the inside of the guide nozzle 49 through the threaded sliding sleeve 412. When the weft yarn is limited, the two sets of oppositely arranged connecting pressure plates 414 can lock the weft yarn under the threaded sliding of the micro motor 416 and the positioning screw 415, thereby improving the automation level of subsequent guidance.

[0045] Working principle: Before use, if it is necessary to pass the weft yarn to the outside of the guide nozzle 49, the user can position the weft yarn inside the connecting pressure plate 414 through the alignment guide tube 5. The two sets of micro motors 416 can synchronously drive the positioning screw 415 to rotate, which in turn causes the positioning screw 415 to drive the threaded slide block 413 to slide threadedly. This causes the two sets of threaded slide blocks 413 to drive the connecting pressure plate 414 to move centripetally, thereby locking and limiting the required weft yarn. Then, the stepper motor 46 starts, which drives the limit gear 48 to rotate. The limit gear 48 drives the connecting gear ring 44 to mesh and rotate. When the connecting gear ring 44 rotates, it can synchronously drive the two sets of guide gears 45 to mesh and rotate, thereby enabling the two sets of guide gears 45 to synchronously drive the connecting screw 42 to rotate. The two sets of connecting screws 42 can then be threadedly connected to the threaded sliding sleeve 412, thereby driving the alignment slide 411 to move to the other side opening through the guide nozzle 49. At this time, the external lead wire module can guide the weft yarn limited by the two sets of connecting pressure plates 414 into the inside of the guide roller 31 to complete the weft yarn guiding operation. When the weft yarn is being sprayed and guided, the servo motor 35 can adjust the weft yarn output speed through the two sets of guide rollers 31 to improve the stability of the weft yarn guiding.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
