Description

Technical Field

[0001] The utility model relates to the technical field of polyester filament fabric production, in particular to a pre-humidifying device used for the production of polyester filament fabric. Background Art

[0002] Polyester filament is made of polyester. Polyester is an important variety of synthetic fibers and is the trade name of polyester fiber in my country. It is made of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) as raw materials, and is made of polyethylene terephthalate (PET) through esterification or transesterification and polycondensation reaction. The fiber is made through spinning and post-treatment, and pre-humidification of polyester filament fabrics is also a relatively important link.

[0003] The patent with publication number CN 218561819 U discloses a pre-humidification device for the production of polyester filament fabrics, which includes a humidification box, an adjustment mechanism is arranged inside the humidification box, and the adjustment mechanism includes a bidirectional threaded rod and a bevel gear 2, and the bidirectional threaded rod is rotatably connected to the inner wall of the humidification box. The device enables people to adjust the humidification range when pre-humidifying polyester filament fabrics with a larger width, thereby effectively avoiding the situation that the polyester filament fabrics with a larger width cannot be fully humidified when humidifying due to the inability to adjust the humidification range. However, the device has the problem of passing the polyester filament fabrics to be pre-humidified through the guide rollers at both ends, and then adjusting the position of the water storage tank according to the width of the fabric, but the water storage tank, the nozzle and each transmission structure are all located in the humidification box and cannot be directly seen, so it is difficult to accurately adjust the water spray range according to the width of the fabric, thereby affecting the humidification effect of the fabric. For this reason, a pre-humidification device for the production of polyester filament fabrics is proposed to solve the problem that the existing pre-humidification device is difficult to accurately control the water spray range according to the fabric size.

[0024] Example: See Figure 1-5A pre-humidification device for the production of polyester filament fabrics, comprising a humidification box 1, notches 2 are provided at both ends of the humidification box 1, two groups of conveying rollers 3 are provided in the inner cavity of the front notch 2, a humidification tube 4 is provided in the inner cavity of the humidification box 1, a plurality of nozzles 5 are provided at the bottom of the humidification tube 4, a water pump 6 and a water tank 7 are provided at the top of the humidification box 1, a water inlet pipe 8 is provided at the top of the water tank 7, an adjustment cylinder 9 is provided at the outer rings of both sides of the humidification tube 4, a sealing groove 10 is provided at the bottom of the inner cavity of the adjustment cylinder 9, electric push rods 11 are fixedly connected to both sides of the humidification box 1, connecting arms 12 are provided at both sides of the humidification box 1, and a limit plate 13 is fixedly connected to the bottom of the connecting arm 12. The water pump 6 is interconnected with the humidification tube 4 and the water tank 7, and the water inlet pipe 8 is interconnected with the water tank 7. The adjustment cylinder 9 is sleeved on the outside of the humidification tube 4, and the bottom of the nozzle 5 is in extrusion contact with the bottom of the inner cavity of the sealing groove 10. The connecting arm 12 is fixedly connected to the adjusting cylinder 9, and one side of the electric push rod 11 is fixedly connected to the connecting arm 12. When the limit plate 13 is moved to contact the boundary of the fabric by using the electric push rod 11 to cooperate with the connecting arm 12, the adjusting cylinder 9 also cooperates with the sealing groove 10 to seal the nozzle 5 of the humidifying tube 4 as the connecting arm 12 moves, so as to accurately adjust the water spraying range of the humidifying tube 4 according to the width of the fabric.

[0025] The horizontal axis of the limit plate 13 is flush with the horizontal axes of the two conveying rollers 3, and the surface of the limit plate 13 is smooth. The left limit plate 13 is flush with the right side of the adjustment cylinder 9. When the limit plate 13 is moved to contact the boundary of the fabric by the electric push rod 11, the adjustment cylinder 9 also cooperates with the sealing groove 10 with the movement of the connecting arm 12 to block the nozzle 5 of the humidifying tube 4, so that the water spraying range of the humidifying tube 4 is equal to the spacing of the limit plate 13 and the width of the fabric, so as to realize the precise adjustment of the spraying range according to the width of the fabric, and the surface of the limit plate 13 is smooth to avoid large friction with the fabric, and it can also play a certain limiting role on the outgoing fabric. A water inlet slot 14 is provided on the front of the humidifying box 1 and a collecting bucket 15 is fixedly connected thereto. A second water pump 16 is provided at the bottom of the inner cavity of the humidifying box 1. A connecting pipe 17 is provided on the right side of the humidifying box 1. The connecting pipe 17 is communicated with the water inlet pipe 8 and the humidifying box 1. A valve 18 is provided on the top of the connecting pipe 17. As the pre-humidified fabric is transmitted from the conveying roller 3, part of the water will also move out of the humidifying box 1 with the fabric and will be collected by the collecting bucket 15 and will flow into the bottom of the humidifying box 1 from the water inlet slot 14. At this time, the second water pump 16 and the valve 18 are turned on, so that the collected water can be re-introduced from the connecting pipe 17 through the water inlet pipe 8 into the water tank 7 to continue the fabric humidification operation, thereby improving the utilization rate of water resources and the convenience of using the collected water. A stabilizing groove 19 is provided on the back of the connecting arm 12, and a stabilizing plate 20 is provided in the inner cavity of the stabilizing groove 19.

The stabilizing groove 19 and the stabilizing plate 20 on the connecting arm 12 are utilized to improve the stability of the connecting arm 12 during relative movement, that is, the stability during adjustment of the water spray range.

[0026] Working principle: When using this pre-humidification device for the production of polyester filament fabrics, the polyester filament fabric that needs to be pre-humidified passes through the slot 2 and out from between the conveying rollers 3, and then the electric push rod 11 is used to drive the limit plate 13 at the bottom of the connecting arm 12 to move toward the middle until it contacts the boundary of the passed fabric. At this time, the adjustment cylinder 9 also cooperates with the sealing slot 10 to seal the nozzle 5 of the humidification tube 4 as the connecting arm 12 moves, so that the water spraying range of the humidification tube 4 is equal to the spacing of the limit plate 13 and the width of the fabric, which solves the problem that it is difficult to accurately control the water spraying range of the existing polyester fabric according to the fabric size. Then the water source can be connected to the water inlet pipe 8 to introduce the water into the water tank 7, and the water pump 6 can be turned on to introduce the water into the humidification tube 4 and sprayed from the nozzle 5 to pre-humidify the polyester filament fabric.
