Description

Technical Field

[0001] The utility model belongs to the technical field of chemical fibers and relates to a secondary oiling device which can be easily disassembled. Background Art

[0002] With the expansion of the application scope of industrial yarns, in the production process of activated polyester filaments, anti-wicking, seawater-repellent yarns and other differentiated varieties that need to be oiled for the second time, it is necessary to oil the yarn bundles after multi-stage hot roller drawing and network knotting for the second time with functional oil. When the yarn bundles are oiled with the functional oil for the second time, an oiling device must be used to ensure the stability of the yarn bundle tension and the uniform oiling of the functional oil.

[0003] At present, the stretching and winding equipment for preparing polyester industrial yarn in my country is imported from Germany's Barmag Company and Japan's TMT Company. The functional additive oiling technology for polyester industrial yarn mainly involves adding one or more oil nozzle oiling devices for oiling before winding and forming. In the secondary oiling devices of the prior art with one or more oil nozzles, such as the oiling devices of CN201120332291.6 and CN201420661689.8, the yarn bundle directly enters the oil nozzle for oiling. The oil nozzle is prone to coking, wear and breakage due to the large friction force during continuous use, and is difficult to clean or replace in time; when other varieties that do not require secondary oiling are produced at the spinning position where this oiling device is installed, the entire two-pass oiling equipment must be dismantled, which takes a long time; if the secondary oiling equipment is not dismantled, the yarn bundle must also pass through the relevant oil nozzles and wire guide porcelain parts of the oiling device, otherwise it will hit the main body of the oiling device, causing the yarn bundle to bend and change direction multiple times, increasing the tension and aggravating the friction with the porcelain parts, which is likely to cause abnormal physical properties of the finished silk and an increase in poor spinning conditions and hairy silk. It also takes a long time to install it again, which greatly affects the production efficiency.

[0004] Therefore, it is of great practical significance to design a secondary oiling device that is easy to disassemble. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a secondary oiling device which is easy to disassemble;

[0006] In order to achieve the above purpose, the scheme adopted by the utility model is as follows:

[0007] A secondary oiling device that can be easily disassembled comprises an oiling device body, a bracket fixing rod, an oil nozzle bracket and an oil nozzle; the bracket fixing rod is connected to the oiling device body, one end of the oil nozzle bracket is connected to the peripheral surface of the bracket fixing rod, and the other end of the oil nozzle bracket is connected to the oil nozzle; the secondary oiling device also comprises a bottom plate and a wire guide;

[0008] The main body of the oiling device is a cubic structure with a completely open front. The upper and lower bottom surfaces of the cubic structure have notches on the sides parallel to (not overlapping with) the rear surface of the main body of the oiling device. Along the notch toward the rear of the main body of the oiling device, the upper surface of the upper bottom surface and the upper surface of the lower bottom surface are respectively provided with n embedded grooves, n ≥ 1.

[0009] There are two bottom plates, namely bottom plate I and bottom plate II; bottom plate I and bottom plate II are respectively provided with n embedding grooves, bottom plate I is detachably fixedly connected to the upper bottom surface, and bottom plate II is detachably fixedly connected to the lower bottom surface; the embedding grooves on bottom plate I are respectively fitted with the embedding grooves on the upper bottom surface to form n holes; the embedding grooves on bottom plate II are respectively fitted with the embedding grooves on the lower bottom surface to form n holes;

[0010] The wire guide comprises a wire guide hook fixing frame and a wire guide hook; the number of the wire guides is 2n, and the wire guide hook fixing frames of the wire guides are respectively inserted into the holes and have an interference fit with the holes;

[0011] The bottom plate is detachably fixedly connected to the main body of the oiling device. When the secondary oiling is not needed, only the bottom plate needs to be removed without removing the entire secondary oiling device.

[0012] As the preferred technical solution:

[0013] As described above, a simple to disassemble secondary oiling device is provided with threaded holes on the bottom plate I, the bottom plate II, the upper bottom surface and the lower bottom surface; the bottom plate I and the upper bottom surface are detachably fixedly connected by fixing screws passing through the threaded holes, and the bottom plate II and the lower bottom surface are detachably fixedly connected by fixing screws passing through the threaded holes.

[0014] In the easily disassembled secondary oiling device as described above, a small hole is provided on the wire guide hook fixing frame; some fixing screws pass through the small hole on the wire guide hook fixing frame, thereby fixing the wire guide hook fixing frame, thereby ensuring the stability of the wire guide.

[0015] In the above-mentioned secondary oiling device which is easy to disassemble, the bracket fixing rod passes through the left side and the right side of the oiling device body; the oil nozzle bracket is located between the left side and the right side of the oiling device body; the number of the bracket fixing rods is 2, the number of the oil nozzle brackets on the two bracket fixing rods is n, and the number of the oil nozzles is n;

[0016] Before the yarn bundle enters the oil nozzle, it first contacts the wire guide hook on the bottom plate and then enters the oil nozzle, which reduces the friction tension with the oil nozzle and reduces the generation of oil mist.

[0017] In the simple-to-disassemble secondary oiling device as described above, when n≥2, the oil nozzle brackets on the same bracket fixing rod are parallel and coplanar.

[0018] In the simple-to-disassemble secondary oiling device as described above, the wire guide hook fixing frame is fixedly connected to the wire guide hook by an adhesive.

[0019] As described above, a secondary oiling device that is easily disassembled has its left and right sides formed into a right-angled trapezoid, wherein the upper side of the right-angled trapezoid is 2 to 5 cm smaller than the lower side; the upper side of the right-angled trapezoid is connected to the upper bottom surface, and the lower side of the right-angled trapezoid is connected to the lower bottom surface. The size is designed in this way so that the lower bottom surface can catch the oil drops dripping from the oil nozzle in the secondary oiling device to prevent them from dripping onto the winding machine.

[0020] Beneficial Effects

[0021] (1) The utility model provides a secondary oiling device that is easy to disassemble. When the spinning position equipped with the oiling device produces other products that do not require secondary oiling, only the bottom plate needs to be removed, and the secondary oiling device does not need to be completely removed. The disassembly is simple, which improves the practicality of the device.

[0022] (2) The utility model provides a secondary oiling device that is easily disassembled and has a simple design. After the yarn bundle enters the oiling device, it first passes through a wire guide porcelain component to reduce the large friction tension generated when the yarn bundle directly contacts the oil nozzle, thereby reducing the generation of oil mist.
