Abstract
Description
Technical Field
[0001] This application relates to the field of cotton textile technology, for example to a drying apparatus for cotton spinning production. Background Technology
[0002] Currently, cotton yarn is yarn produced from cotton fibers through spinning processes. During the production of cotton yarn, after processes such as carding and drawing, the cotton yarn will contain a certain amount of moisture. Drying can remove this excess moisture, bringing the moisture regain of the cotton yarn to a suitable range. Generally, the moisture regain of cotton yarn is controlled at around 7%-8%, which facilitates subsequent processing and storage.
[0003] Existing cotton yarn drying methods involve using drying equipment to dry the cotton yarn on a conveyor belt with hot air.
[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:
[0005] Because the cotton yarn on the conveyor belt has a certain thickness, the inner layer of the cotton yarn heats up slowly during the hot air drying process, requiring more time to dry the inner layer of the cotton yarn, resulting in relatively low efficiency.
[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.
[0008] This disclosure provides a drying apparatus for cotton spinning production to increase the heating rate of the inner layer of cotton yarn, reduce the drying time of the inner layer of cotton yarn, and improve the drying efficiency.
[0009] In some embodiments, a drying apparatus for cotton spinning production includes: a housing, conveyor belts, drying ducts, a hot air box, and a drying insert. Multiple conveyor belts are provided and spaced apart within the housing; the drying ducts extend through the housing and have drying air outlets located within the housing; the hot air box is movably disposed within the housing and located above one of the conveyor belts; the drying insert has multiple air outlets connected to the lower side wall of the hot air box, and the drying insert communicates with the hot air box.
[0010] Optionally, multiple drying tubes are provided, and one end of each drying tube extends through the lower side wall of the hot air box into the hot air box. Some of the drying tubes can rotate relative to the hot air box.
[0011] Optionally, a rotating disk is provided on one side of the hot air box, and a sliding rod is provided on the rotating disk. The sliding rod is slidably connected to the rack frame, and the rack frame engages with the outer wall of part of the drying tube. The rack frame is slidably connected to the hot air box.
[0012] Optionally, the lower end of the drying cannula gradually narrows.
[0013] Optionally, the top of the hot air box is slidably connected to the movable frame in the horizontal direction; and the movable frame is slidably connected to the inner wall of the box in the vertical direction.
[0014] Optionally, a lead screw is rotatably mounted on the movable frame, and the lead screw is threadedly connected to the top of the hot air box.
[0015] Optionally, the movable frame is connected to the output end of the electric push rod, and the electric push rod is connected to the inner side wall of the housing.
[0016] Optionally, multiple drying ducts are provided, with some drying ducts located on the upper side of multiple conveyor belts and others located on the lower side of multiple conveyor belts.
[0017] The drying apparatus for cotton spinning production provided in this disclosure can achieve the following technical effects:
[0018] Multiple conveyor belts transport the cotton yarn inside the drying chamber, injecting hot air into the drying ducts and hot air box. The hot air is then blown onto the cotton yarn on the conveyor belts through drying vents, drying it. The hot air box moves within the machine, causing the drying tubes to move towards the inner layer of the cotton yarn. The hot air from the hot air box is then blown onto the inner layer of the cotton yarn through the drying tubes and multiple outlets. This increases the heating rate of the inner layer of the cotton yarn, reduces the drying time, and improves drying efficiency.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0035] Combination Figure 1-2 As shown, this embodiment of the present disclosure provides a drying device for cotton spinning production, including: a housing 100, conveyor belts 200, drying ducts 300, a hot air box 400, and a drying insert 500. Multiple conveyor belts 200 are provided and spaced apart within the housing 100; the drying ducts 300 extend through the housing 100 into the housing 100 and are provided with drying air outlets 310 located within the housing 100; the hot air box 400 is movably disposed within the housing 100 and located above one of the conveyor belts 200; the drying insert 500 is provided with multiple air outlets 510, connected to the lower side wall of the hot air box 400, and the drying insert 500 communicates with the hot air box 400.
[0036] The cotton spinning production drying apparatus provided in this embodiment transports cotton yarn within a housing 100 via multiple conveyor belts 200. Hot air is injected into the drying duct 300 and the hot air box 400, and then blown onto the cotton yarn on the conveyor belts 200 through drying air outlets 310 to dry it. The hot air box 400 moves within the housing, causing the drying insert 500 to move towards the cotton yarn, allowing the drying insert 500 to insert into the inner layer of the cotton yarn. The hot air in the hot air box 400 is then blown onto the inner layer of the cotton yarn through the drying insert 500 and multiple air outlets 510. This increases the heating rate of the inner layer of the cotton yarn, reduces the drying time of the inner layer, and improves the drying efficiency.
[0037] Combination Figure 3 As shown, optionally, one end of the hot air box 400 is connected to the hose 410, and the other end of the hose 410 extends through the box body 100 to the outside of the box body 100. In this way, since the hot air box 400 is movably disposed inside the box body 100, and connected to the hot air box 400 via the hose 410, the hose 410 can change accordingly during the movement of the hot air box 400, resulting in better adaptability. External hot air is then delivered into the hot air box 400 through the hose 410, and then flows into the box body 100 or blown onto the inner layer of the cotton yarn through the drying pipe 500 and multiple air outlets 510.
[0038] Understandably, hot air is heated by an external heat source and then sent into the hose 410 or the drying air duct 300. Alternatively, the heating element can be installed in the drying air duct 300 and the hot air box 400 to heat the air.
[0039] Specifically, the box 100 is equipped with a feed inlet and a discharge outlet.
[0040] Optionally, multiple drying tubes 500 are provided, and one end of each drying tube 500 extends through the lower side wall of the hot air box 400 into the hot air box 400. Some of the drying tubes 500 can rotate relative to the hot air box 400. In this way, when multiple drying tubes 500 are inserted into the inner layer of the cotton yarn, some of the drying tubes 500 can rotate relative to the hot air box 400, and thus rotate inside the cotton yarn. The air outlet 510 then discharges air while rotating, resulting in a more uniform air distribution area.
[0041] Optionally, the top end of the drying tube 500 is provided with a first limiting protrusion 520 and a second limiting protrusion 530, and the lower side wall of the hot air box 400 is sandwiched between the first limiting protrusion 520 and the second limiting protrusion 530. In this way, the risk of the drying tube 500 detaching from the hot air box 400 is reduced by the cooperation of the first limiting protrusion 520 and the second limiting protrusion 530.
[0042] Combination Figure 4As shown, optionally, a rotating disk 540 is provided on one side of the hot air box 400, and a sliding rod 550 is provided on the rotating disk 540. The sliding rod 550 is slidably connected to the rack frame 560, and the rack frame 560 engages with the outer wall of part of the drying tube 500. The rack frame 560 is also slidably connected to the hot air box 400. In this way, when the rotating disk 540 rotates, it drives the sliding rod 550 to rotate. The sliding rod 550 slides relative to the rack frame 560, and drives the rack frame 560 to move back and forth. The rack frame 560 then slides relative to the hot air box 400, thereby driving the drying tube 500, which is engaged with the rack frame 560, to rotate back and forth. The air outlet 510 then discharges air while rotating, resulting in a more uniform air distribution area.
[0043] Optionally, the rack holder 560 is provided with a sliding hole 561, which is slidably connected to the sliding rod 550. In this way, the sliding rod 550 and the sliding hole 561 cooperate, and the connection stability is relatively high.
[0044] Optionally, the rotating disk 540 is connected to the output end of the first motor 541, which is connected to the hot air box 400 via a motor bracket. In this way, the first motor 541 provides power for the rotation of the rotating disk 540.
[0045] Specifically, gears 570 are fixedly installed on the outer wall of the drying tube that can rotate relative to the hot air box 400.
[0046] Specifically, gear 570 and rack carrier 560 mesh.
[0047] Optionally, the lower end of the drying tube 500 gradually narrows. This facilitates smoother insertion of the drying tube 500 into the inner layer of the cotton yarn. It also reduces the risk of the cotton yarn being pulled by the drying tube 500 when it moves away from the cotton yarn.
[0048] Optionally, the top of the hot air box 400 is slidably connected to the movable frame 600 in the horizontal direction; and the movable frame 600 is slidably connected to the inner wall of the box body 100 in the vertical direction. This allows the top of the hot air box 400 to slide relative to the movable frame 600, so that when the drying tube 500 is inserted into the cotton yarn, the hot air box 400 moves along with the cotton yarn, reducing the risk of displacement of the drying tube 500 relative to the cotton yarn. The movable frame 600 slides relative to the inner wall of the box body 100, thereby moving the hot air box 400 and the drying tube 500, allowing the drying tube 500 to be inserted into or moved away from the cotton yarn. After the drying operation, the drying tube 500 moves away from the cotton yarn and moves to the next area of cotton yarn for drying.
[0049] Combination Figure 5As shown, optionally, a sliding block 420 is provided on the top of the hot air box 400, and the sliding block 420 is slidably connected to the movable frame 600. In this way, the sliding block 420 and the movable frame 600 slide relative to each other, and the connection stability is relatively high.
[0050] Specifically, there are two sliding blocks 420, and each sliding block 420 is slidably connected to the movable frame 600. In this way, there are relatively more connection points, the connection stability is relatively high, and the risk of movement and displacement of the hot air box 400 is reduced.
[0051] Optionally, a lead screw 610 is rotatably mounted on the movable frame 600, and the lead screw 610 is threadedly connected to the top of the hot air box 400. In this way, the rotation of the lead screw 610 drives the hot air box 400 to move relative to the movable frame 600, which has relatively high stability, and the lead screw 610 can also provide guidance for the movement of the hot air box 400.
[0052] Optionally, one end of the lead screw 610 is connected to the output end of the second motor 620, which is connected to the movable frame 600 via a motor frame. In this way, the second motor 620 provides power for the rotation of the lead screw 610.
[0053] Optionally, the movable frame 600 is connected to the output end of the electric push rod 630, which is connected to the inner side wall of the housing 100. In this way, the electric push rod 630 provides power for the movable frame 600 to slide relative to the housing 100.
[0054] Optionally, the outer side wall of the movable frame 600 abuts against the inner side wall of the housing 100. In this way, the inner side wall of the housing 100 provides guidance and restraint for the movable frame 600, reducing the risk of the movable frame 600 sliding or deviating.
[0055] Optionally, multiple drying ducts 300 are provided, with some drying ducts 300 located on the upper side of multiple conveyor belts 200 and others located on the lower side of multiple conveyor belts 200. In this way, both the upper and lower sides of the cotton yarn can be dried, resulting in a relatively better drying effect.
[0056] Combination Figure 6 As shown, optionally, the housing 100 is provided with an air guide plate 110, which is located on the lower side of the multiple conveyor belts 200 and on one side of the drying air duct 300 located on the lower side of the multiple conveyor belts 200. In this way, the air guide plate 110 guides the air, allowing the hot air to be blown more effectively to the lower side of the cotton yarn.
