Description

Technical Field

[0001] The utility model relates to the technical field of PTFE processing, in particular to a production device for PTFE fine staple fibers. Background Art

[0002] Polytetrafluoroethylene (Teflon or PTFE) is a polymer compound formed by the polymerization of tetrafluoroethylene, which can be made into polytetrafluoroethylene tubes, rods, belts, plates, films, etc. It can be made into short fibers to make high temperature resistant filter materials, corrosion resistant filter materials in the chemical and pharmaceutical industries, PTFE non-woven fabrics, etc.

[0003] The main process of PTFE processing is melting, spinning, drawing, cutting, and finally packaging the fine short fibers. Other operations are also required to assist in the processing. For example, spinning needs to be quenched after melting, and softening needs to be performed during drawing. The existing quenching and softening operations are performed using different instruments. Since they are different cold and hot operations, they are generally placed in different positions. However, the above operations are performed during the drawing process, and the drawing itself requires a large space. In order to make rational use of the space, multiple wire guide rollers are staggered. There will be a situation where the fiber filaments enter from one direction and are guided by the drawing and then exported from the same direction. The fiber filaments entering and exported are arranged side by side longitudinally. The layout of the wire guide rollers must also take into account the quenching equipment and softening equipment, which increases the difficulty of layout and also requires more space. For this reason, a device that can take into account both quenching and softening functions is needed to cooperate with PTFE production. Utility Model Content

[0004] Based on this, it is necessary to provide a production device for PTFE fine staple fibers to address the problem that the existing quenching equipment and softening equipment are placed separately, which increases the difficulty of laying out the guide rollers and occupies space.

[0030] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0031] Example 1

[0032] See also Figure 1 This embodiment introduces a production device for PTFE fine staple fibers, which mainly includes a guiding mechanism 1, a water tank mechanism 2 and a splicing mechanism 3.

[0033] The guide mechanism 1 mainly comprises a first guide box 11, a second guide box 12, an atomizer 13 and a guide roller 14. The first guide box 11 and the second guide box 12 have the same structure, but are longitudinally symmetrically arranged. The two are longitudinally symmetrical and have a fixed spacing through the splicing mechanism 3, and the two are also connected as one.

[0034] The top of the first guide box 11 and the bottom of the second guide box 12 are hinged with box plates, and the inside of the first guide box 11 and the second guide box 12 can be checked by rotating the box plates. The box plates can be closed or opened during operation. The first guide box 11 and the second guide box 12 have openings on both sides symmetrically in the length direction, and the guide roller 14 is rotatably arranged in the openings. The axial direction of the guide roller 14 is consistent with the width direction of the first guide box 11 and the second guide box 12, and the fiber line can pass through the first guide box 11 and the second guide box 12 under the guidance of the guide roller 14.

[0035] like Figure 4 and Figure 6 As shown, the atomizer 13 of the first guide box 11 is located as a whole below the guide roller 14, and the atomizer 13 of the second guide box 12 is located as a whole above the guide roller 14, which meets the requirements of hot air going up and cold air going down. The atomizer 13 is arranged on the other two symmetrical sides of the first guide box 11 and the second guide box 12. The atomizer 13 includes an atomizer tube 131 and an atomizer nozzle 132; one end of the atomizer tube 131 extends obliquely from the outside of the first guide box 11 or the second guide box 12 to the inner wall, and one end of the atomizer tube 131 located inside the first guide box 11 or the second guide box 12 faces the fiber and is connected to the atomizer nozzle 132. The atomizer nozzle 132 adopts the existing atomizer nozzle structure. It is mainly composed of a nozzle, a pressure device and a liquid storage device. When the liquid passes through the nozzle, due to the special structure of the nozzle and the effect of pressure, the liquid will be dispersed into tiny droplets and form a mist. The atomizing tubes 131 on the first guide box 11 and the second guide box 12 are symmetrically arranged, so that the fiber line can be softened or cooled in the same direction.

[0036] like Figure 2 As shown, the splicing mechanism 3 includes a plug sleeve 32 and a plug rod 31. If the plug sleeves 32 are installed at the bottom four corners of the first guide box 11, the plug rods 31 adapted to the plug sleeves 32 are installed at the top four corners of the second guide box 12, and vice versa. The diameter of the plug rod 31 is adapted to the inner diameter of the plug sleeve 32, so the plug rod 31 can be inserted into the plug sleeve 32 with clearance fit. The plug sleeve 32 and the plug rod 31 can be fixed by bolts to prevent the two from being separated.

[0037] The water tank mechanism 2 includes a water storage tank 21, a water distribution tank 22, a heater 23 and a water pump 24. The water storage tank 21 is installed on the top of the second guide box 12 and is located within the range surrounded by the plug rod 31 or the plug sleeve 32. The water storage tank 21 is connected to the external water supply equipment, and a water level sensor or an observation window can be set to observe the water level. The water distribution tank 22 is arranged on the outside of the first guide box 11 and the second guide box 12, preferably on the side wall where the atomizer 13 is installed, so that the end of the atomizer tube 131 can be located in the water distribution tank 22. The water distribution tank 22 on the first guide box 11 is connected, and similarly, the water distribution tank 22 on the second guide box 12 is also connected. Preferably, two water pumps 24 are set, one water pump 24 supplies the water in the water storage tank 21 to the water distribution tank 22 of the first guide box 11, and the other water pump 24 supplies the water distribution tank 22 on the second guide box 12. The water pump 24 can be installed outside the water storage tank 21, or can be installed on the first guide box 11 or the second guide box 12, depending on the actual situation.

[0038] In order to meet the softening requirements of the first guide box 11, a heater 23 is provided inside the water distribution tank 22 on the first guide box 11. The heater 23 adopts the existing heater 23 and is used to heat the water in the water distribution tank 22, so that the atomizing nozzle 132 sprays high-temperature mist. The water distribution tank 22 of the second guide box 12 can use normal temperature water. If lower temperature water is required, a refrigerator can be set. The refrigerator adopts the existing equipment to cool the water distribution tank 22 of the second guide box 12. The extra heat generated by the refrigerator can be guided into the first guide box 11.

[0039] In this embodiment, a symmetrical first guide box 11 for softening and a second guide box 12 for cooling are arranged. The two are spliced ​​into one body and are in opposite directions. They do not affect each other and can save space. They cooperate with the stretching in the same direction and do not affect the original layout of the wire guide rollers.

[0040] Example 2

[0041] like Figure 5 As shown, this embodiment introduces a PTFE fine short filament fiber production device, which is different from the PTFE fine short filament fiber production device introduced in Example 1. The difference is that the atomizing pipe 131 on the first guide box 11 and the second guide box 12 of this embodiment is staggered. The staggered setting of the atomizing pipe 131 can reduce the situation where the atomizing nozzles 132 conflict with each other, but the single spraying range is limited.

[0042] This embodiment has the same beneficial effects as Embodiment 1.

[0043] Example 3

[0044] This embodiment introduces a production device for PTFE fine staple fibers, which is different from the production device for PTFE fine staple fibers introduced in Example 1. The difference is that the outer wall of the insertion rod 31 of this embodiment is provided with a telescopic block, and the insertion sleeve 32 is correspondingly provided with a through hole adapted to the telescopic block. When the insertion rod 31 is inserted into the insertion sleeve 32, the telescopic block is compressed, and when the telescopic block moves to the through hole, the telescopic block stretches and can enter and pass through, completing the limiting connection between the insertion rod 31 and the insertion sleeve 32. The telescopic block adopts the existing spring telescopic block.

[0045] This embodiment has the same beneficial effects as Embodiment 1.

[0046] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
