Description

Technical Field

[0001] The invention relates to the field of textile equipment, in particular to a high-speed air jet loom which is convenient for heat dissipation. Background Art

[0002] The air jet loom is a shuttleless loom that uses a jet of air to pull the weft yarn through the shed. The air jet loom uses air as the weft insertion medium, and uses the ejected compressed air flow to generate friction traction on the weft yarn to pull the weft yarn, bring the weft yarn through the shed, and achieve the purpose of weft insertion through the jet generated by the air jet. During the operation of the air jet loom, the power mechanism (such as the motor) in the air jet loom will generate heat, causing the equipment to heat up, and the heat is transferred to the yarn and fabric, affecting the quality of the finished fabric. When the textile device is weaving fabrics, the yarn will also fall off due to friction. The textile silk will adhere to the air jet loom, which is difficult to clean. The textile silk will also adhere to the yarn or fabric finished product, affecting the quality of the fabric.

[0003] Chinese patent publication number CN214168272U discloses a high-speed jet loom that is easy to dissipate heat, including a machine support column, a heat dissipation device, an electrostatic adsorption box, a motion motor and a textile device. A hollow support frame is welded and installed on the top of the machine support column, and two heat dissipation devices are installed through the inside of the hollow support frame. A motion motor is welded and installed on the outer side of one side of the machine support column through a support plate, and a textile device is installed above the motion motor, and the textile device is located on the inner side of the machine support column, and an electrostatic adsorption box is placed and installed on the inner side of the machine support column.

[0004] However, the above patent has the following defects:

[0005] 1. A cooling wire is installed inside the heat dissipation device, which generates cold air and blows out the cold air through the outlet fan and the suction fan to cool the machine. However, the fan will blow the wind onto the weft yarn at the shed. The blowing force on the weft yarn may cause the weft yarn to be misaligned, so that the weft yarn cannot pass through the shed, which interferes with the normal weft insertion process and thus affects the weaving process.

[0006] Second, the textile threads that fall off during the weaving process may still be attached to the yarn or fabric in other areas under the blowing force of the fan, affecting the quality of the finished fabric and failing to achieve effective collection. Summary of the invention

DETAILED DESCRIPTION

[0032] Embodiment 1

[0033] like Figure 1-4 As shown, the present invention proposes a high-speed air jet loom that is easy to dissipate heat, including a diverter cylinder 1, an opening and closing mechanism, a filter plate 7, a collecting box 8, a refrigerator (not shown), a connecting frame 29 and a textile equipment body with a power mechanism.

[0034] The shunt cylinder 1 is vertically arranged on the connecting frame 29, and the connecting frame 29 is arranged on the textile equipment body. The shunt cylinder 1 has an air inlet 101 at the top, an air outlet 102 at the bottom, an air duct 103 on one side horizontally, and a discharge port 104 on the other side horizontally; two groups of opening and closing mechanisms are arranged side by side in the vertical direction inside the shunt cylinder 1, and the two groups of opening and closing mechanisms are respectively located at the air inlet 101 and the air outlet 102; the filter plate 7 is arranged on the inner wall of the shunt cylinder 1, and one side of the filter plate 7 is located at the bottom of the discharge port 104, and the other side of the filter plate 7 is located at the bottom of the discharge port 104. One end is located above the air duct 103, and the filter plate 7 is inclined from bottom to top along the direction from one lateral end to the other lateral end; the collecting box 8 is connected with the diverter cylinder 1 through the discharge port 104; the refrigerator is arranged inside the diverter cylinder 1, and is located between the filter plate 7 and the opening and closing mechanism at the air outlet 102; the power mechanism is transmission-connected with an air extraction and supply mechanism for reciprocatingly drawing air from the diverter cylinder 1 and exhausting air into the diverter cylinder 1 through the air duct 103, thereby realizing the alternating opening and closing of the two sets of opening and closing mechanisms to intermittently draw air from the air inlet 101 and exhaust air to the air outlet 102.

[0035] This embodiment can cool down the hot air and collect the fallen textile yarns without interfering with the weaving process. It uses the air pressure difference to inhale the hot air and textile yarns instead of blowing the wind directly onto the weft yarns, which will not affect the weft insertion process and the weaving process. When in use, the air pumping mechanism uses the power of the power mechanism to extract and exhaust air, saving the use cost. The air pumping mechanism first extracts air from the diverter tube 1 through the air duct 103, and creates a negative air pressure in the diverter tube 1, so that the external air opens the opening and closing mechanism located above under the action of the air pressure difference, and the opening and closing mechanism located below is in a closed state. The external hot air and the fallen textile yarns enter the diverter tube 1 from the air inlet 101 under the action of the air pressure difference. The hot air is cooled by the refrigerator, and the textile yarns slide down along the inclined filter plate 7 and enter the collection box 8 through the discharge port 104 to realize the collection of the textile yarns. The air extraction mechanism then exhausts air into the diverter tube 1 through the air duct 103, creating positive air pressure in the diverter tube 1, so that the external air opens the opening and closing mechanism located below under the action of the air pressure difference, and the opening and closing mechanism located above returns to the closed state, and the cooled air is discharged to the outside of the diverter tube 1 through the air outlet 102, thereby achieving the cooling and discharge of the hot air. Under the continuous operation of the air extraction mechanism, the hot air can be intermittently drawn in and cooled, and the textile silk can be collected and processed.

[0036] When considering the timing of the air extraction mechanism to extract air, the air extraction mechanism can be used to exhaust air into the diverter cylinder 1 when the jet loom performs jet weft insertion. At this time, air will not be extracted through the air inlet 101, so that the weft insertion process and the exhaust process can be staggered, preventing the diverter cylinder 1 from exhausting air from above and affecting the process of the weft yarn passing through the shuttle eye, thereby further reducing the impact on the weft insertion process.

[0037] Embodiment 2

[0038] The present invention proposes a high-speed air jet loom that is easy to dissipate heat. Compared with the first embodiment, in this embodiment, Figure 5-6 As shown, the opening and closing mechanism includes a swinging assembly, a swinging frame 5 and an elastic member 6. A plurality of swinging assemblies are arranged side by side in the transverse direction. The swinging assembly includes a wing plate 2, a rotating rod 3 and a connecting platform 4. The wing plate 2 has a mounting groove 201 at the end in the length direction. The wing plate 2 gradually tilts from bottom to top toward the side where the air duct 103 is located. The two ends in the length direction of the wing plate 2 fit with the inner wall of the diverter tube 1 to ensure the sealing effect in the closed state (even if the condition of complete sealing cannot be achieved, it can still play a certain separation role. When the air is pumped through the air pumping mechanism, it can still be used to create negative air pressure and positive air pressure, and the purpose of intermittently opening the two sets of opening and closing mechanisms can still be achieved, which does not affect the process of drawing in hot air for cooling and then discharging it. It does not affect the collection process of the fallen textile yarns), the wing plate 2 is arranged on the rotating rod 3, and the two sides of the wing plate 2 in the thickness direction are respectively provided with a blade strip 202 and a blade groove 203, the blade strip 202 is consistent with the blade groove 203, and a plurality of blade strips 202 and blade grooves 203 are arranged side by side. When the wing plate 2 reciprocates to the fitting state and the open state, the blade strip 202 can cut off a part of the textile yarns located there (the blade strip 202 can be used alone to cut off the textile yarns brought by the wind, and the blade strip 202 can also be used to cut off the textile yarns at the blade groove 203), so that the size and weight of a single section of textile yarn are smaller, and it can be more easily entered into the diversion cylinder 1, and can be more easily entered into the collection box 8, thereby improving the collection effect of the textile yarns. At the same time, the plurality of blades 202 can play a role of separation and pressure bearing on the upper side of the wing plate 2. The air pressure can act on the blades 202 on the basis of acting on the wing plate 2, so that the air pressure can act more evenly and effectively on different areas on the upper side of the wing plate 2, thereby improving the utilization of the air pressure and shortening the time it takes for the wing plate 2 to be turned. In the initial state, the top of the outermost wing plate 2 on one side of the air duct 103 is tightly attached to the inner wall of the diverter tube 1 to achieve sealing.

[0039] The rotating rod 3 is rotatably arranged on the diverter tube 1, the distance between the central axis of the rotating rod 3 and the top of the wing plate 2 is smaller than the distance between the central axis of the rotating rod 3 and the bottom of the wing plate 2, the connecting platform 4 is arranged at the end of the wing plate 2, the swing frame 5 is rotatably connected with the multiple connecting platforms 4 in the multiple swing components, one end of the elastic member 6 is connected to the inner wall of the diverter tube 1, and the other end of the elastic member 6 is connected to the outermost wing plate 2 facing the side where the air duct 103 is located, and the connection point is lower than the height of the rotating rod 3. When the multiple swing components of the opening and closing mechanism are rotated, the multiple wing plates 2 are rotated, and the wing plates 2, the rotating rod 3, the connecting platform 4 and the swing frame 5 can form a parallelogram structure, so that the multiple wing plates 2 can be rotated synchronously, and the space between any two adjacent wing plates 2 can be used for circulating air and textiles, and the space between the two outermost wing plates 2 and the inner wall of the diverter tube 1 can also be used for circulating air and textiles.

[0040] The collection box 8 is provided with an anti-backflow plate 10 and an electrostatic absorber 9 from top to bottom. The anti-backflow plate 10 is an inverted "V" shaped structure. A plurality of anti-backflow plates 10 are arranged side by side in the horizontal direction, and a feeding channel is formed between adjacent anti-backflow plates 10. The collection box 8 is in a sealed state when in use, which can ensure that the air extraction mechanism effectively creates negative air pressure and positive air pressure in the diverter tube 1. The textile yarn can enter the collection box 8 through the discharge port 104, pass through the feeding channel, and be adsorbed at the electrostatic absorber 9. The anti-backflow plate 10 with an inverted "V" shaped structure can effectively prevent the textile yarn from flowing from bottom to top, prevent backflow, and ensure the collection effect of the textile yarn.

[0041] For the high-speed air jet loom that is easy to dissipate heat, in the initial state before operation, the wing plates 2 in the two sets of opening and closing mechanisms are sequentially sealed against each other, the top end of the wing plate 2 at one end is in sealing contact with the inner wall of the diverter tube 1, the elastic member 6 is connected to the wing plate 2 at this end, and the bottom end of the wing plate 2 at the other end is in sealing contact with the inner wall of the diverter tube 1, so that the two sets of opening and closing mechanisms are in a closed state; the method during operation includes the following steps:

[0042] S1. Start the power mechanism, which drives the textile equipment body to operate to perform textile operations. The power mechanism also drives the air pumping mechanism to operate. The air pumping mechanism uses the power of the power mechanism without setting up a new power supply structure, thereby achieving the utilization rate of the power of the existing power mechanism and not increasing the operating cost.

[0043] S2, the air pumping mechanism first draws air from the shunt tube 1 through the air duct 103 to create negative air pressure in the shunt tube 1. Under the action of the pressure difference between the inside and outside of the shunt tube 1, the multiple wing plates 2 in the upper opening and closing mechanism are synchronously turned open, and air is drawn through the air inlet 101 to draw in the hot air around the power mechanism and the textile equipment body and the textile threads that fall off during the textile process. The textile threads are intercepted by the filter plate 7, and the textile threads slide along the filter plate 7 and enter the collection box 8 through the discharge port 104. The textile threads pass through the feeding channel and are adsorbed by the electrostatic adsorber 9; the hot air is cooled by the refrigerator; during this process, the opening and closing mechanism located below is in a closed state. After the opening and closing mechanism located below is opened once, when the opening and closing mechanism located above is in the opening process, the opening and closing mechanism located below will first close and then maintain a closed state for a certain period of time.

[0044] The distance from the central axis of the rotating rod 3 to the top of the wing plate 2 is smaller than the distance from the central axis of the rotating rod 3 to the bottom of the wing plate 2. The distance from the central axis of the rotating rod 3 to the bottom of the wing plate 2 is defined as the lever a, and the distance from the central axis of the rotating rod 3 to the top of the wing plate 2 is defined as the lever b. Then the lever a is greater than the lever b. The wing plate 2 gradually tilts from bottom to top toward the side where the air duct 103 is located. The top of the wing plate 2 at one end is in sealing contact with the inner wall of the diverter tube 1, and the elastic member 6 is connected to the wing plate 2 at this end. The bottom of the wing plate 2 at the other end is in sealing contact with the inner wall of the diverter tube 1. When it is necessary to rotate the wing plate 2 from the closed state, the wing plate 2 will inevitably compress the elastic member 6, and the bottom end of the wing plate 2 rotates below the rotating rod 3, and the top end of the wing plate 2 rotates above the rotating rod 3.

[0045] When the air pumping mechanism first draws air from the diverter tube 1 through the air duct 103, the air pressure inside the diverter tube 1 decreases, and the pressure of the external air will act on the flaps 2 in the two sets of opening and closing mechanisms from the outside of the diverter tube 1. However, when the air pressure is applied to the flaps 2 in the upper opening and closing mechanism, the force arm a will be used as the force arm (if the force arm b is used as the force arm, the flaps 2 will be pressed more firmly and will not open). When the air pressure is applied to the flaps 2 in the lower opening and closing mechanism, the force arm b will be used as the force arm. The lever arm (if the lever arm a is used as the action lever arm, the wing plate 2 will be pressed more firmly), the lever arm a is greater than the lever arm b. When the external air pressure overcomes the elastic force of the elastic member 6 to finally make the wing plate 2 rotate open, the external air pressure will first reach the level of opening the wing plate 2 located above. When the wing plate 2 in the upper opening and closing mechanism is rotated open, the external air will only enter the diverter tube 1 from the air inlet 101, and then pass through the multiple wing plates 2 staggered side by side, and the opening and closing mechanism below is still in a closed state.

[0046] S3. The air extraction mechanism then supplies air to the diverter tube 1 through the air duct 103 to create positive air pressure in the diverter tube 1, and blows off the textile threads remaining on the filter plate 7, so that the textile threads enter the electrostatic adsorber 9 in the collecting box 8. Under the action of the pressure difference between the inside and outside of the diverter tube 1, the multiple wing plates 2 in the opening and closing mechanism located below are synchronously opened, and the cooled air is discharged to the production environment through the air outlet 102, which will not cause the ambient temperature to rise. In the initial process of the air extraction mechanism supplying air to the diverter tube 1, the opening and closing mechanism located above is switched to a closed state by the elastic force of the elastic member 6, and maintains a closed state when the diverter tube 1 is exhausted through the air outlet 102.

[0047] When the air pumping mechanism exhausts air into the diverter tube 1 through the air duct 103, the internal air pressure of the diverter tube 1 increases, and the pressure of the internal air will act on the wing plates 2 in the two sets of opening and closing mechanisms from the inside of the diverter tube 1. Similarly, when the air pressure is applied to the wing plates 2 in the upper opening and closing mechanism, the force arm b will be used as the force arm, and when the air pressure is applied to the wing plates 2 in the lower opening and closing mechanism, the force arm a will be used as the force arm, and the force arm a is greater than the force arm b. When the internal air pressure overcomes the elastic force of the elastic member 6 to finally make the wing plates 2 open, the internal air pressure will first reach the level of opening the wing plates 2 located below. When the wing plates 2 in the opening and closing mechanism located below are turned open, the internal air will only be discharged from the diverter tube 1 from the air outlet 102, that is, the air cooled by the refrigerator will be discharged.

[0048] S4, cycle S2-S3, intermittently draw in hot air first, and then discharge the cooled air. During the process of drawing and exhausting air, the textile yarns flowing with the hot air are collected in the collection box 8 to prevent interference with the weaving process.

[0049] Embodiment 3

[0050] The present invention proposes a high-speed air jet loom that is easy to dissipate heat. Compared with the first embodiment, in this embodiment, Figure 2 As shown, the power mechanism includes a motor 13 and a rotating shaft a14, and the textile equipment body also includes a transmission mechanism 24, a textile device 25 and a base 30. The base 30 has an installation space, and a filter screen a31 is arranged on the base 30. The motor 13 is arranged in the base 30, and the motor 13 is connected to the rotating shaft a14 by driving. The rotating shaft a14 is rotatably arranged on the base 30, and the rotating shaft a14 is connected to the textile device 25 by driving through the transmission mechanism 24. The motor 13, as a power source, can drive the rotating shaft a14 to rotate, and the rotating shaft a14 drives the textile device 25 to run through the transmission mechanism 24, and the textile device 25 is used to weave fabrics. The above structures are all structures of air jet looms in the prior art. The motor 13 will generate heat when running, and the heat can be dissipated to the outside of the base 30 through the filter screen a31. The filter screen a31 plays a certain role in isolating debris, preventing debris in the external air from entering the inside of the base 30, avoiding attachment to the motor 13 and the transmission mechanism 24, and avoiding affecting the power transmission process.

Based on the third embodiment, in this embodiment, Figure 2As shown, the air inlet 101 is connected to the air inlet scoop 28, and the air inlet scoop 28 is connected to the air inlet pipe 27. The air inlet pipe 27 is a "Y"-shaped pipe. The air inlet pipe 27 is arranged horizontally, and the bottom end of the air inlet pipe 27 is connected to the air inlet scoop 28. A connected air suction pipe is vertically arranged on the air inlet pipe 27. The air suction pipe is located below the weaving device 25. When negative air pressure is generated in the diverter tube 1, air will be sucked in through the air suction pipe, and the textile fibers that fall off during the weaving process will be sucked into the air suction pipe. The top of the air inlet pipe 27 has an air suction port, and the air suction port faces the filter screen a31. The air suction port will draw the hot air emitted from the filter screen a31 into the air inlet pipe 27. Air and textile fibers will enter the air inlet scoop 28 through the air inlet pipe 27, and continue to flow into the diverter tube 1. The arrangement of the air inlet pipe 27 and the air inlet scoop 28 can be more conducive to the inhalation of air and textile fibers, expand the operating range, and be more conducive to heat dissipation and the collection of fallen textile fibers.

[0053] like Figure 1 As shown, a wind dispersing platform 26 is provided on the machine base 30, and the wind dispersing platform 26 includes a wind guide platform portion and a wind guide plate portion integrally connected from top to bottom, and the wind guide platform portion is a conical structure or a pyramidal structure with the top of the cone facing upward, which is conducive to wind guidance, and the top of the wind guide platform portion faces the air outlet 102. When the cooled air is discharged from the diverter tube 1, it will be blown onto the wind guide platform portion, guided by the wind guide platform portion, and then flow out along the wind guide plate portion, rather than being blown directly onto the ground, so as to prevent dust from being stirred up, avoid polluting the textile environment, and prevent the yarn and finished fabric from being contaminated.
