Description

Technical Field

[0001] This utility model relates to a chemical fiber blowing device, belonging to the field of chemical fiber production equipment. Background Technology

[0002] Chemical fibers, or synthetic fibers for short, are fibers with textile properties produced from natural or synthetic polymers through processes such as preparing spinning solutions, spinning, and post-treatment. In various chemical fiber production equipment, the doffing channel of the cutting machine is the passageway that transports the cut short chemical fibers to the packaging machine. Due to the different physical properties of different chemical short fibers, the doffing pattern of the cut short fibers within the channel varies.

[0003] Chinese utility model patent CN220012914U discloses a blowing device for a fiber-feeding channel in a cutting machine. The device includes a connecting pipe, multiple air-blowing pipes, and multiple nozzles. The two ends of the connecting pipe are connected to form a ring structure. The multiple air-blowing pipes and nozzles are located on one side of the connecting pipe near the center of the ring structure. An air supply mechanism is provided on the other side of the connecting pipe to supply compressed air into the connecting pipe. The multiple air-blowing pipes are distributed along the axis of the connecting pipe, and each connecting pipe corresponds to one nozzle. One end of each air-blowing pipe is mounted on the connecting pipe, and the nozzle is installed at the other end of the air-blowing pipe. The air-blowing pipe is connected to the connecting pipe. This blowing device for a fiber-feeding channel in a cutting machine disperses the short chemical fibers by delivering air to the fiber-feeding channel and acting on them. This improves the dispersion effect of the chemical fiber products, prevents the fibers from clumping after cutting, and avoids the fibers in the packaged product from being difficult to loosen, thus improving the package weight ratio. In the existing technology, the nozzles are evenly distributed around the circumference. Although the air discharged from the nozzles has a certain dispersion effect on the chemical fibers, the airflow generated by the two opposite nozzles pushes the chemical fibers, which easily causes the chemical fibers to clump together. That is, the chemical fibers in the center of the doffing channel gather together to form clumps, which makes it difficult for the fibers in the packaged package to loosen and results in a low package weight rate.

[0004] Therefore, a chemical fiber dispersing device is needed to improve the dispersion effect of chemical fibers. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, to provide a chemical fiber blowing device to improve the dispersion effect of chemical fibers.

[0009] In the two dispersing mechanisms, the two sets of jet components in one dispersing mechanism are distributed left and right, while the two sets of jet components in the other dispersing mechanism are distributed front and back.

[0015] Preferably, the system also includes multiple adsorption mechanisms, each comprising an adsorption main pipe and four sets of adsorption branch pipes. The two ends of the adsorption main pipe are connected to form a U-shaped structure. The four sets of adsorption branch pipes are respectively arranged on the inner walls of the front, back, left, and right sides of the U-shaped structure of the adsorption main pipe.

Moreover, the adsorption force generated by the adsorption tube disperses the chemical fibers in the fiber dropping channel to the surrounding areas, further improving the dispersion effect of the chemical fibers.

[0032] Nozzle 121, nozzle 122;

[0033] Adsorption main pipe 41, adsorption branch pipe 42, and extraction pipe 43. Detailed Implementation

[0034] like Figure 1-8 As shown, a chemical fiber blowing device in this embodiment includes two blowing mechanisms 1, one above the other.

[0035] The blowing mechanism 1 includes a connecting pipe 11, the two ends of which are connected to form a loop structure. A set of jet components 12 are connected to the inner sidewalls of both sides of the loop structure of the connecting pipe 11. The connecting pipe 11 is connected to an air source.

[0036] Two sets of jet assemblies 12 on the same connecting pipe 11 are arranged in an alternating manner;

[0037] In the two blowing mechanisms 1, the two sets of jet components 12 in one blowing mechanism 1 are distributed from left to right, and the two sets of jet components 12 in the other blowing mechanism 1 are distributed from front to back;

[0038] During the operation of the cutting machine, the cut short chemical fibers are conveyed to the inner doffing channel 5, which is located within the U-shaped structure of the connecting pipe 11. At this time, compressed air is delivered to the connecting pipe 11 through the air source. The compressed air in the connecting pipe 11 is then delivered to the doffing channel 5 through the jet assembly 12 and acts on the chemical fibers, causing the short chemical fibers in the doffing channel 5 to disperse, thereby improving the dispersion effect of the chemical fiber products and preventing the cut fibers from clumping together, which would make it difficult to loosen the fibers in the packaged product. This improves the fixed weight rate of the packaged product. The compressed air discharged by the two sets of jet assemblies 12 distributed on the left and right causes the short chemical fibers in the doffing channel 5 to disperse in the left and right direction, while the compressed air discharged by the two sets of jet assemblies 12 distributed in front and back causes the short chemical fibers in the doffing channel 5 to disperse in the front and back direction. Furthermore, because the two sets of jet assemblies 12 on the same connecting pipe 11 are arranged in an alternating manner, it can prevent the chemical fibers in the center of the doffing channel 5 from accumulating and forming clumps, thus improving the dispersion effect of the chemical fibers.

[0039] It should be noted that the length of the chemical fiber is less than the distance between the two blowing mechanisms 1, so as to avoid the chemical fiber being subjected to the dispersing force in the left and right and up and down directions at the same time and getting tangled.

[0040] Each group of nozzle 122 components is provided with multiple nozzles, and multiple jet components 12 in the same group are arranged side by side. Specifically, multiple jet components 12 on the left and right sides are distributed in the front-back direction, and multiple jet components 12 on the front and back sides are distributed in the left-right direction.

[0041] The jet assembly 12 includes a nozzle 121 and a nozzle 122. One end of the nozzle 121 is connected to the connecting pipe 11, and the nozzle 122 is installed at the other end of the connecting pipe 11. In fact, the yarn dropping channel 5 has a spray hole 6 for accommodating the nozzle 121 and the nozzle 122. During operation, compressed air in the connecting pipe 11 is delivered from the nozzle 121 to the nozzle 122, and the nozzle 122 discharges the compressed air and delivers it into the yarn dropping channel 5.

[0042] An input branch pipe 2 is provided between the two connecting pipes 11. The two ends of the input branch pipe 2 are respectively connected to the two connecting pipes 11. The middle end of the input branch pipe 2 is connected to the input main pipe 3. The input main pipe 3, the input branch pipe 2 and the connecting pipes 11 are all made of stainless steel. During operation, the air source first delivers compressed air to the input main pipe 3. The compressed air in the input main pipe 3 is then delivered to the input branch pipe 2. The compressed air in the input branch pipe 2 is delivered from both ends to the two connecting pipes 11.

[0043] It also includes multiple adsorption mechanisms 4, specifically three adsorption mechanisms 4 are provided, and the three adsorption mechanisms 4 and two connecting pipes 11 are arranged alternately from top to bottom.

[0044] The adsorption mechanism 4 includes an adsorption main pipe 41 and four sets of adsorption branch pipes 42. The two ends of the adsorption main pipe 41 are connected to form a U-shaped structure. The four sets of adsorption branch pipes 42 are respectively arranged on the inner walls of the front, back, left, and right sides of the U-shaped structure of the adsorption main pipe 41. An air extraction pipe 43 is connected to the adsorption main pipe 41. The air extraction pipe 43 is connected to an air extraction system, which can be an air pump. The inner diameter of the adsorption branch pipes 42 is 25mm. During operation, the fiber dropping channel 5 is placed inside the U-shaped structure of the adsorption main pipe 41, and there are adsorption holes 7 on the fiber dropping channel 5. The adsorption branch pipes 42 are placed inside the adsorption holes 7. The air in the air extraction pipe 43 is intermittently extracted by the air extraction system. In this way, the air in the adsorption branch pipes 42 is intermittently transported from the adsorption main pipe 41 to the air extraction pipe 43, so that the adsorption pipe intermittently adsorbs the air in the fiber dropping channel 5. Through the adsorption force, the chemical fibers in the fiber dropping channel 5 are dispersed to the surrounding area, thereby further improving the dispersion effect of the chemical fibers.

[0045] In summary, by staggering the two vertically distributed blowing mechanisms 1 and the two sets of jet components 12 on the same connecting pipe 11, the chemical fibers in the doffing channel 5 are dispersed sequentially in the left-right and front-back directions, preventing the chemical fibers in the center of the doffing channel 5 from clustering together and forming clumps, thus improving the dispersion effect of the chemical fibers. Moreover, the adsorption force generated by the adsorption pipe disperses the chemical fibers in the doffing channel 5 to the surrounding areas, further improving the dispersion effect of the chemical fibers.

[0046] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
