[0002] Corduroy is a dense, velvety cotton fabric, usually made of a pure cotton yarn frame. It is softer and more comfortable than ordinary pure cotton and has better thermal insulation performance. The air jet loom is a shuttleless loom that uses a jet airflow to pull the weft yarn through the shed. Its working principle is to use air as the weft insertion medium, and the compressed air jet generates friction traction on the weft yarn to pull the weft yarn through the shed, thereby achieving the purpose of weft insertion. The warp loosening device is a very common auxiliary tool in the use of the air jet loom, and its main purpose is to adjust the tension of the warp.

[0003] According to patent No. CN109056164A, a warp loosening device for an air jet loom comprises a first frame and a second frame, one side of the first frame is fixedly connected with a first adjusting rod by bolts, a first adjusting hole is provided on the first adjusting rod, and a first adjusting plate is sleeved on the first adjusting rod, one side of the bottom of the first adjusting plate is fixedly connected with a motor by bolts, a side of the motor close to the first adjusting plate is rotatably connected with a rotating shaft, and a first connector is installed on one end of the rotating shaft relative to the motor, the present invention is provided with a first adjusting rod, a second adjusting rod, a first adjusting plate, a first adjusting hole, a first adjusting plate, a second adjusting plate and a second adjusting hole, so that when a user needs to connect the device with the first frame and the second frame, the device can be used with air jet loom frames of different specifications, and there is no need to purchase warp loosening devices of different specifications, thereby reducing the use cost.

[0004] However, during the use of the above-mentioned patent, although the device can be used in conjunction with air-jet loom frames of different specifications, when the staff installs rollers and warp-loosening rollers of different lengths, they still need to repeatedly turn and disassemble multiple sets of bolts to change the spacing between the adjustment plates. Only then can the rollers and warp-loosening rollers of different lengths be installed. In addition, the adjustment of the spacing between the adjustment plates is limited by the position of the adjustment hole on the adjustment rod, which results in the position adjustment of the adjustment plate being not flexible enough, thereby affecting the use of the warp-loosening device.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 4 The utility model provides a technical solution: a warp easing device for a corduroy jet loom, comprising a frame 1, a servo motor 2 and a warp easing roller 6, a servo motor 2 is arranged below the frame 1, and a mounting seat 3 is docked at the output end of the servo motor 2, and a rotating plate 4 is docked at one side of the outer wall of the mounting seat 3, a rotating plate 4 is connected to a rotating roller 5 at the top end through a supporting rod, and a rotating plate 4 is connected to a warp easing roller 6 at the bottom end through a supporting column, an adjusting mechanism 7 is arranged on the outer wall of the rotating roller 5, and the adjusting mechanism 7 comprises a driving motor 701, a rotating column 702, a first bevel gear 703, a second bevel gear 704, a transmission plate 705, a guide rod 706, a mounting plate 707, a limiting column 708, a spring 709 and a sliding rod 710, a mounting plate 707 is sleeved on the outer wall of the mounting seat 3, and a sliding rod 710 is slidably connected to the top of the mounting plate 707, and both sides of the outer wall of the sliding rod 710 It is welded with the frame 1, and a driving motor 701 is installed in the middle of the top of the frame 1, and a rotating column 702 is connected to the output end of the driving motor 701; a first bevel gear 703 is sleeved in the middle of the outer wall of the rotating column 702, and the outer wall of the first bevel gear 703 is meshed and connected with a second bevel gear 704; a transmission plate 705 is docked at the bottom end of the second bevel gear 704, and guide rods 706 are rotatably connected on both sides of the outer wall of the transmission plate 705; the side of the guide rod 706 away from the transmission plate 705 is connected to the mounting plate 707 through a rotating seat, and the middle part of the mounting plate 707 is slidably connected to a limiting column 708; springs 709 are sleeved on both sides of the outer wall of the limiting column 708, and both sides of the outer wall of the limiting column 708 are welded to the frame 1; an elastic telescopic mechanism is formed between the mounting plate 707, the limiting column 708 and the spring 709, and the limiting column 708 and the sliding rod 710 are parallel to each other.

[0025] In specific implementation, in the process of adjusting the warp yarn of the corduroy air jet loom by the warp loosening device, it is necessary to adjust the spacing between the mounting plates 707, and then when installing different types of rollers 5 and warp loosening rollers 6, first start the driving motor 701 on the frame 1 to drive the rotating column 702 to rotate. Since the rotating column 702 is connected to the first bevel gear 703, the rotation of the rotating column 702 drives the first bevel gear 703 to rotate, and since the first bevel gear 703 and the second bevel gear 704 are meshed, the rotation of the first bevel gear 703 drives the second bevel gear 704 to rotate, and then the rotation of the second bevel gear 704 drives the transmission plate 705 to rotate;

[0026] Because the transmission plate 705 and the guide rod 706 are rotatably connected, the transmission plate 705 rotates to drive the guide rod 706 to rotate. At this time, the angle between the guide rod 706 and the transmission plate 705 changes, thereby generating a thrust on the mounting plate 707, so that the mounting plates 707 move away from each other. Moreover, because the mounting plate 707 is slidably connected to the limiting column 708 and the sliding rod 710, the mounting plate 707 also squeezes the spring 709 when moving, causing the spring 709 to deform, and then the spring 709 is reset to assist the mounting plate 707 to return to its original position.

[0027] Until the mounting plate 707 moves to the specified position, the spacing between the mounting plates 707 is automatically adjusted, which makes it convenient for the staff to install different types of rollers 5 and warp easing rollers 6, and the replacement can be completed without repeatedly turning multiple sets of bolts, saving time and energy, thereby facilitating the adjustment of the spacing when the warp easing device of the corduroy air-jet loom is used.

[0028] See also Figure 1 , Figure 2 and Figure 5 It can be seen that an auxiliary mechanism 8 is arranged on the outer wall of the frame 1, and the auxiliary mechanism 8 includes a bevel gear A801, a bevel gear B802, a threaded rod 803, a threaded column 804 and a supporting telescopic column 805. A fixed base 9 is arranged above the frame 1, and supporting telescopic columns 805 are installed on both sides of the top of the frame 1, and the top of the supporting telescopic column 805 is connected to the fixed base 9; the side of the rotating column 702 away from the driving motor 701 is sleeved with a bevel gear A801, and the outer wall of the bevel gear A801 ​​is meshed and connected with the bevel gear B802; the threaded rod 803 is connected inside the bevel gear B802, and the outer wall of the threaded rod 803 is threadedly connected with the threaded column 804; the top of the threaded column 804 is connected to the fixed base 9, and the bottom end of the bevel gear A801 ​​is connected to the frame 1 through a bearing seat.

[0029] In a specific implementation, in the process of adjusting the warp yarn of the corduroy air jet loom by the warp loosening device, since the rotating column 702 is connected to the bevel gear A801, the rotating column 702 drives the bevel gear A801 ​​to rotate together, and since the bevel gear A801 ​​is meshingly connected with the bevel gear B802, the rotation of the bevel gear A801 ​​drives the bevel gear B802 to rotate, and then the rotation of the bevel gear B802 drives the threaded rod 803 to rotate, and since the threaded rod 803 is threadedly connected to the threaded column 804, the top of the threaded column 804 is connected to the fixed base 9;

[0030] At this time, the total length between the threaded rod 803 and the threaded column 804 changes, and then the distance between the frame 1 and the fixed base 9 changes, and then the height of the frame 1 changes. At this time, the frame 1 is assisted to move by the extension of the supporting telescopic column 805 until the warp easing roller 6 and the turning roller 5 reach the specified position, and then when installing different types of turning rollers 5 and warp easing rollers 6, their heights are adjusted at the same time, and then the position of the warp yarn passing through the turning roller 5 and the warp easing roller 6 meets the needs of the staff, thereby facilitating the height adjustment when the warp easing device of the corduroy jet loom is used.

[0031] In summary, when the warp easing device of the corduroy jet loom is used, the warp easing device is first installed on the jet loom through the fixed base 9, and then the warp yarn passes through the rotating roller 5 and the easing roller 6, and then the servo motor 2 is started to drive the mounting seat 3 to rotate, and the rotation of the mounting seat 3 drives the rotating plate 4 to rotate, and then the rotating plate 4 drives the easing roller 6 to rotate. At this time, the position of the rotating roller 5 is fixed, and the position of the easing roller 6 swings, thereby changing the tension of the warp yarn, ensuring that the warp yarn tension remains relatively uniform during the weaving process, thereby achieving the purpose of easing the warp. This is a prior art and will not be elaborated on here. The mounting plate 707 is moved to the specified position through the adjusting mechanism 7, and then the spacing between the mounting plates 707 is automatically adjusted, so that the staff can install different types of rotating rollers 5 and easing rollers 6, and the replacement can be completed without repeatedly rotating multiple sets of bolts, saving time and energy. When installing different types of rotating rollers 5 and easing rollers 6, the heights thereof are adjusted at the same time through the auxiliary mechanism 8. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
