Description

Technical Field

[0001] This utility model relates to the field of polypropylene processing technology, specifically to a polypropylene staple fiber dyeing device. Background Technology

[0002] Polypropylene staple fiber (PSF) is not a fabric; it is a form of polypropylene fiber. PSF is a textile raw material, usually produced by the polymerization reaction of propylene monomers, and then processed to form short fibers.

[0003] In traditional devices, the inconvenient removal method may cause the fibers to become knotted, stretched, or rubbed during the removal process, which may damage the dyeing effect or the fibers.

[0004] Secondly, when there is no flowing water, the dye is prone to sedimentation or concentration in certain areas, leading to changes in the concentration of the dyeing solution and affecting the dyeing quality.

[0005] Finally, without a yarn cover frame, polypropylene fibers are easily knotted and tangled by the water flow during the dyeing process, forming clumps. This not only affects the dyeing effect but also increases the difficulty of subsequent operations. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1:

[0031] Please see Figures 1-5A polypropylene staple fiber dyeing device includes a main body 1, a lifting mechanism, and a dyeing mechanism. The lifting mechanism includes a lifting platform 2, a lifting cylinder 3, rollers 4, a yarn cover frame 5, and a fixing assembly. The lifting platform 2 is mounted on the main body 1 and slidably connected to the main body 1. The lifting cylinder 3 is fixedly mounted inside the main body 1, and its output end is fixedly connected to the lifting platform 2. The rollers 4 are mounted on the lifting platform 2 and slidably connected to the main body 1. The yarn cover frame 5 is fixedly mounted on the lifting platform 2. The fixing assembly includes a mounting shaft 6, a pressure rod 7, and a rotating frame 8. The mounting shaft 6 is respectively mounted in the pressure rod 7 and the rotating frame 8. The mounting shaft 6 is connected to the main body 1. The pressure rod 7 is mounted on the yarn cover frame 5 and slidably connected to the yarn cover frame 5. The rotating frame 8 is mounted on the pressure rod 7 and rotatably connected to both the pressure rod 7 and the mounting shaft 6.

[0032] In this embodiment, the lifting mechanism includes a lifting platform 2, a lifting cylinder 3, rollers 4, a yarn cover frame 5, and a fixing component. In use, polypropylene fibers are manufactured into yarn cover rolls to facilitate the dyeing of polypropylene fibers. After the yarn cover rolls are placed into the yarn cover frame 5 and slid and fixed, the yarn cover frame 5 can be placed inside the main body 1 for dyeing. At this time, the lifting cylinder 3 is driven to directly drive the lifting platform 2 to slide on the main body 1. The rollers on the lifting platform 2 rotate in the lifting platform 2 and the limiting block 16, and correspondingly slide in the first sliding groove 14 and the second sliding groove 15 of the positioning rod 13, which facilitates the smooth sliding of the lifting platform 2. The sliding between the limiting block 16 and the positioning rod 13 makes the lifting of the lifting platform 2 more stable. After the lifting platform 2 contacts the main body 1, the insert 17 at the bottom of the lifting platform 2 enters the interior of the main body 1 to prevent water from splashing out.

[0033] In this embodiment, the fixing assembly includes a mounting shaft 6, a pressure rod 7, and a rotating frame 8. During use, the yarn rolls made of polypropylene fiber need to be placed into the stop bar of the rotating frame 8, thus creating a gap between each yarn roll to prevent tangling and knotting. After the yarn rolls are installed on the rotating frame 8, the pressure rod 7 can be inserted through the insertion hole 21 on the support plate 19, allowing it to enter the support plate 19. Then, the mounting shaft 6 installed in the pressure rod 7 is rotated. Under the positioning effect of the insertion hole 21, the screw 22 on the mounting shaft 6 engages with the yarn frame. The threaded holes 20 on the 5 cooperate to fix each other, and during this process, the limiting holes 24 on the rotating frame 8 also cooperate with the limiting rods 23 on the support plate 19. The screw 22 at one end of the mounting shaft 6 installed on the rotating frame 8 is also inserted into the corresponding threaded holes 20, so that the fixing components can be fixed inside the yarn package frame 5. The function of the rotating frame 8 is to automatically make the rotating frame 8 vertical when the yarn package roll is installed on the rotating frame 8, which facilitates the installation of the yarn package roll. The mounting shaft 6 bears the pressure of the rotating frame 8 to prevent the polypropylene that has been soaked in pigment after dyeing from deforming the rotating frame 8 due to increased weight.

[0034] In this embodiment, the dyeing mechanism includes a water spray component 9, a connecting component 10, a control valve 11, and a fixing plate 12. When the lifting platform 2 contacts the main body 1, the control valve 11 can be opened to pump pigmented water into the connecting component 10. Subsequently, the dyeing water slides into the water spray component 9 through the connecting component 10, and then enters the yarn package frame 5 through the flow hole 18 on the yarn package frame 5 to dye the yarn package roll. At the same time, the control valve 11 on the other side of the main body 1 is opened, and the water spray component 9 fixedly installed on the main body 1 through the fixing plate 12 forms a negative pressure to draw the pigment water inside the main body 1. Under the action of the water spray component 9 and other components on both sides of the main body 1, the pigment water flows and washes the yarn package roll in the yarn package frame 5, so that the polypropylene fiber is dyed evenly.

[0035] Example 2:

[0036] In summary, during use, the polypropylene fiber yarn rolls must first be placed into the stop bar of the rotating frame 8. This spacing between each yarn roll prevents tangling and knotting. After the yarn rolls are installed on the rotating frame 8, the pressure rod 7 can be inserted through the insertion hole 21 on the support plate 19. Then, the mounting shaft 6 installed in the pressure rod 7 is rotated. Positioned by the insertion hole 21, the screw 22 on the mounting shaft 6 engages with the threaded hole 20 on the yarn frame 5 for fixation. During this process, the limiting hole 24 on the rotating frame 8 also engages with the limiting rod 23 on the support plate 19, and the screw 22 at one end of the mounting shaft 6 on the rotating frame 8 is inserted into the corresponding threaded hole 20, thereby allowing the fixing component to be fixed inside the yarn bag frame 5. The function of the rotating frame 8 is to automatically make the rotating frame 8 vertical when the yarn bag roll is installed on it, which facilitates the installation of the yarn bag roll. The mounting shaft 6 bears pressure on the rotating frame 8 to prevent the polypropylene dyed with pigment after dyeing from deforming the rotating frame 8 due to increased weight. Then, the yarn bag is controlled. Frame 5 is placed inside the main body 1 for dyeing. At this time, the lifting cylinder 3 is driven, directly causing the lifting platform 2 to slide on the main body 1. The rollers on the lifting platform 2 rotate in the lifting platform 2 and the limiting block 16 respectively, and correspondingly slide in the first sliding groove 14 and the second sliding groove 15 of the positioning rod 13, which facilitates the smooth sliding of the lifting platform 2. The sliding between the limiting block 16 and the positioning rod 13 makes the lifting of the lifting platform 2 more stable. After the lifting platform 2 contacts the main body 1, the insert 17 at the bottom of the lifting platform 2 enters the interior of the main body 1 to prevent water from splashing out. Finally, the... The control valve 11 is opened, and pigmented water is pumped into the connector 10. The dyeing water then slides into the water sprayer 9 through the connector 10, and then enters the yarn package frame 5 through the flow hole 18 on the yarn package frame 5 to dye the yarn package roll. At the same time, the control valve 11 on the other side of the main body 1 is opened, and the water sprayer 9 fixed on the main body 1 by the fixing plate 12 forms a negative pressure to draw the pigment water inside the main body 1. Under the action of the water sprayer 9 and other components on both sides of the main body 1, the pigment water flows and washes the yarn package roll in the yarn package frame 5, so that the polypropylene fiber is dyed evenly.

For all the fixed connections mentioned above, welding is preferred.
