Description

Technical Field

[0001] The invention relates to the technical field of textiles, in particular to a spinning and drawing constant temperature box. Background Art

[0002] The nascent yarn obtained after chemical fiber spinning is still unstable and has poor physical and mechanical properties, such as large elongation, low strength, and unstable size. It needs further post-processing. The most important processing steps are drawing and heat setting. Drawing is usually achieved through a drawing roller. The yarn is stretched after being wound on the drawing roller, which increases the breaking strength of the fiber, reduces the elongation at break, and improves the wear resistance and fatigue strength to various deformations. Generally, the total stretching multiple of melt-spun fibers is 3-7 times; wet-spun fibers can reach 8-12 times; when producing high-strength fibers, the stretching multiple is even higher, even up to dozens of times. Heat setting is usually achieved by passing a circulating hot fluid into the drawing roller through a mold temperature controller to heat the drawing roller, or passing hot steam into a constant temperature box to place the drawing roller in a constant temperature environment, thereby eliminating the internal stress of the fiber during the fiber drawing process, improving the stability of the fiber size, and further improving the physical and mechanical properties of the fiber.

[0003] A traditional spinning and drawing constant temperature box usually has a wire inlet and a wire outlet, and wire guide plates are respectively arranged at the wire inlet and the wire outlet, the drawing rollers are placed in the constant temperature chamber of the constant temperature box, the constant temperature box is provided with an inspection port, and the constant temperature box is installed with a box door for opening and closing the inspection port. The upstream equipment and / or downstream equipment of the constant temperature box is provided with a broken wire sensor. When the broken wire sensor detects that the yarn is broken, it sends a detection signal to the outside. The staff needs to manually adjust the wire guide plates at the wire inlet and the wire outlet respectively, so as to control the opening size of the wire inlet and the wire outlet. When introducing the filament bundle, the openings of the wire inlet and the wire outlet need to be expanded to make room for operation. During normal drawing work, the openings of the wire inlet and the wire outlet need to be closed to reduce the chimney effect and weaken the heat loss. During the process of winding and normal drafting, the box door needs to be opened manually and the wire inlet and outlet openings need to be adjusted to be smaller. Especially when wire breakage occurs, the operator needs to rewind the wire strips on the drafting roller, and needs to frequently manually open the box door and adjust the wire inlet and outlet openings to be smaller. Since the operator needs to perform more operations when wire breakage occurs, the operation is cumbersome, time-consuming and labor-intensive, which is not conducive to improving production efficiency.

[0034] In order to explain the technical content, structural features, objectives and effects of the invention in detail, the following will be described in detail with reference to the embodiments and accompanying drawings. Figures 1 - 3 The various positional relationships shown in correspondence respectively.

[0035] like Figures 1 - 3 As shown, the automatic induction spinning and drawing constant temperature box includes a box body 1, a box door 2, a first wire guide assembly 3, a second wire guide assembly 4, a first power assembly 5, a second power assembly 6, a third power assembly 7 and a control unit (not shown).

[0036] The top of the box body 1 is provided with a wire inlet 11 and a wire outlet 12, the front is provided with an inspection port 13, and the interior is provided with a constant temperature chamber 14. The box door 2 is movably arranged on the box body 1 and covers the inspection port 13. Specifically, one end of the box door 2 is rotatably connected to the box body 1. The third power assembly 7 is configured to drive the box door 2 to open or close on the inspection port 13 of the box body 1 from the inspection port 13 of the box body 1. Specifically, the third power assembly 7 includes an electric hinge 71 arranged at the connection between the box body 1 and the box door 2. Thus, the electric hinge 71 can drive the box door 2 to open or close on the inspection port 13 of the box body 1 from the inspection port 13 of the box body 1. Of course, in other embodiments, the box door is not limited to being installed on the box body in a rotating connection manner, but can also be slidably connected to the box body. For example, a pair of slide rails are arranged on the upper and lower or left and right sides of the inspection port on the box body, and the box door is slidably arranged on the slide rails through a slider, so that the box door is opened or closed on the inspection port in a slidable manner. In addition, the third power assembly is not limited to the structure of the electric hinge, but can also be a driving structure of a cylinder or a motor screw, for example, the piston rod of the cylinder is connected to the box door or a screw is set between the slider and the motor. The thread inlet and the thread outlet are not limited to being set at the top position of the box body, but can also be set at the left and right sides of the box body.

[0037] In order to maintain a good heat preservation effect in the constant temperature room 14, the box body 1 and the box door 2 are preferably made of heat preservation materials. In addition, in other embodiments, a heat insulation layer can be provided on the inner wall surface of the box body 1 and / or the inner wall surface of the box door 2.

[0038] The box body 1 is provided with a drafting assembly 8, the inlet 11 is located upstream of the drafting assembly 8, the outlet 12 is located downstream of the drafting assembly 8, the drafting assembly 8 includes a drafting roller 81 and a motor 82, the drafting roller 81 is provided on the box body 1 and located in the constant temperature chamber 14, the motor 82 is provided on the box body 1 and is in transmission connection with the drafting roller 81. Thus, the yarn enters the constant temperature chamber 14 of the box body 1 through the inlet 11, is wound around the drafting roller 81, and finally is led out from the outlet 12, and moves to the downstream equipment to continue the post-processing process of the spun fiber.

[0039] In order to heat-set the yarn during its movement, a fluid channel is usually provided inside the drafting roller 81. An injection molding temperature controller is arranged outside the constant temperature box. The injection molding temperature controller is connected to the fluid channel inside the drafting roller through a fluid pipeline, so as to pass a circulating hot fluid, such as hot water, hot oil, etc. into the drafting roller. In addition, hot steam can also be introduced into the constant temperature chamber. For example, a steam generating unit is arranged outside the constant temperature box, and the steam generating unit is connected to the constant temperature chamber through a steam pipeline, so as to input hot steam into the constant temperature chamber, making the drafting roller placed in an environment with constant temperature and humidity. Of course, in other embodiments, the number of drafting assemblies is not limited to one, and more can be provided. The multiple drafting assemblies are arranged alternately in the up-down direction, so that when the yarn moves in the constant temperature chamber, it can be better drafted. This section belongs to the known technology in the prior art and is intended to understand the present invention, so it will not be elaborated here.

[0040] The first wire guiding assembly 3 is arranged at the wire inlet 11, and the first wire guiding assembly 3 is configured to adjust the opening size of the wire inlet 11. The first power assembly 5 is configured to drive the first wire guiding assembly 3 to work. Specifically, the first wire guiding assembly 3 includes a first wire guiding plate 31 and a second wire guiding plate 32. The first wire guiding plate 31 is fixedly arranged at the wire inlet 11, and the second wire guiding plate 32 is movably arranged at the wire inlet 11 in the left-right direction. An inlet wire gap is formed between the first wire guiding plate 31 and the second wire guiding plate 32. The first power assembly 5 includes a first cylinder 51, and the second wire guiding plate 32 is connected to the piston rod of the first cylinder 51. Thus, by adjusting the second wire guiding plate 32, the second wire guiding plate 32 is made to approach or move away from the first wire guiding plate 31, thereby changing the inlet wire gap and adjusting the opening size of the wire inlet 11.

[0041] The second wire guiding assembly 4 is arranged at the wire outlet 12, and the second wire guiding assembly 4 is configured to adjust the opening size of the wire outlet 12. The second power assembly 6 is configured to drive the second wire guiding assembly 4 to work. Specifically, the second wire guiding assembly 4 includes a third wire guiding plate 41 and a fourth wire guiding plate 42. Both the third wire guiding plate 41 and the fourth wire guiding plate 42 are movably arranged at the wire outlet 12 in the left-right direction. An outlet wire gap is formed between the third wire guiding plate 41 and the fourth wire guiding plate 42. The second power assembly 6 includes a second cylinder 61 and a third cylinder 62. The third wire guiding plate 41 is connected to the piston rod of the second cylinder 61, and the fourth wire guiding plate 42 is connected to the piston rod of the third cylinder 62. Thus, by respectively adjusting the third wire guiding plate 41 and the fourth wire guiding plate 42, the third wire guiding plate 41 and the fourth wire guiding plate 42 are made to approach or move away from each other, thereby changing the outlet wire gap and adjusting the opening size of the wire outlet 12.

[0042] The control unit includes a controller and a broken wire sensor. The controller is signal-connected to the broken wire sensor. The broken wire sensor is configured to detect whether the yarn in progress is broken. The controller is respectively control-connected to the first power assembly 5, the second power assembly 6, and the third power assembly 7. The controller is configured to control the first power assembly 5, the second power assembly 6, and the third power assembly 7 to work respectively based on the detection signal fed back by the broken wire sensor. The broken wire sensor is preferably arranged at the wire outlet 12 of the box body 1. Of course, in other embodiments, the broken wire sensor can also be arranged at the wire inlet of the box body or downstream equipment of the constant temperature box, such as an oil leveling device.

[0043] The working principle of the automatic induction type spinning and drawing constant temperature box in this case is as follows: As shown in Figure 3 In the initial state, only a very small gap is formed between the first wire guide plate 31 and the second wire guide plate 32, and the opening size of the wire inlet 11 is relatively small. Only a very small gap is formed between the third wire guide plate 41 and the fourth wire guide plate 42, and the opening size of the wire outlet 12 is relatively small. As shown in Figure 1 The yarn enters the constant temperature chamber 14 from the wire inlet 11, winds around the two drafting rollers 81, and finally is led out from the wire outlet 12. When the broken wire sensor detects that the yarn is broken, the broken wire sensor sends a detection signal to the controller. After receiving the detection signal, the controller respectively sends control signals to the first cylinder 51, the second cylinder 61, the third cylinder 62, and the electric hinge 71. The first cylinder 51 drives the second wire guide plate 32 to move, so that the opening of the wire inlet 11 becomes larger. The second cylinder 61 drives the third wire guide plate 41 to move, and the third cylinder 62 drives the fourth wire guide plate 42 to move, so that the opening of the wire outlet 12 becomes larger. At the same time, the electric hinge 71 drives the box door 2 to open from the maintenance opening 13 of the box body 1. The maintenance personnel can then rewind the broken yarn around the drafting roller 81 through the maintenance opening 13. Compared with the prior art, the operation steps are greatly simplified, the operation is more convenient, and it is beneficial to improve the production efficiency.
