Technical Field

The invention relates to the technical field of textile machinery equipment, in particular to a floating island type infrared drafting hot box.

Background

The hot-drawing process is an operation unit which plays a key role in controlling the final fiber performance in the processing process of chemical fiber filaments, particularly fully drawn chemical fiber filaments. Hot roller drafting is usually adopted in chemical fiber filament bundle processing; whereas monofilaments are often drawn using a liquid bath or hot plate. The hot roller drafting can realize high-speed production, but has the defects of high energy consumption, slow heat transfer, need of multi-turn winding, difficulty in avoiding the temperature difference between air and a roller surface between rollers and the like; however, liquid bath or hot plate drawing is limited by the characteristics of the heat transfer medium, and the heat treatment efficiency is low, so that high-speed production is difficult to realize. The traditional chemical fiber filament heat treatment relies on contact heat conduction to generate heat, and smoke and fiber surface damage are easy to generate.

Detailed Description

In view of the above, the present invention provides a floating island type infrared drafting heat box, which can make the fiber tows in the drafting and tense or loose heat setting process be in the uniformly heated state all the time, so as to be more practical.

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects of the floating island type drafting heat box according to the present invention will be made with reference to the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, with the specific understanding that: both a and B may be included, a may be present alone, or B may be present alone, and any of the three cases can be provided.

Referring to fig. 1 to 33, the floating island type infrared drafting hot box provided by the invention comprises an infrared radiation generating mechanism, a tow bearing mechanism and a fan 25. The tows to be processed are accommodated between the infrared radiation generating mechanism and the tow bearing mechanism, a plurality of air holes 43 are formed in the tow bearing mechanism, and air generated by the fan 25 is transmitted between the infrared radiation generating mechanism and the tow bearing mechanism through the air holes 43.

The floating island type infrared drafting heat box for chemical fibers is characterized in that fibers quickly reach a heated state after absorbing a large amount of infrared waves emitted by an infrared radiation generating mechanism and are then drafted, and the heat of the fibers near a drafting point is possibly concentrated due to the heat release of oriented crystallization in the drafting process, so that the drafting effect is influenced. At this time, the heat of the fiber itself is homogenized by the hot air blown out through the plurality of air holes 43 provided in the tow receiving mechanism, and the stability of the draft point is ensured. In addition, loose heat setting can be adopted in the setting process after the fiber is drafted, upward hot air can hold the fiber, so that the fiber cannot touch the wall or curl when passing through a hot box, and the loose heat setting is smoothly completed.

Wherein the infrared radiation generating means comprises an infrared generator 37 and a radiation means 36. The infrared generator 37 is provided on the radiation mechanism 36. In this embodiment, the radiation mechanism 36 includes an arc plate having a semicircular radial cross section, a first semicircular side plate and a second semicircular side plate, the first semicircular side plate is fixedly connected to one end of the arc plate through the outer circumference thereof, and the second semicircular side plate is fixedly connected to the other end of the arc plate through the outer circumference thereof; the infrared generator 37 is fixedly connected to the first semicircular edge plate and the second semicircular edge plate in the axial direction. In this case, according to the characteristic that light travels in a straight line, infrared light emitted by the infrared generator 37 is reflected by the radiation mechanism 36, and at this time, since the radiation mechanism 36 includes an arc-shaped plate having a semicircular radial cross section, a first semicircular edge plate and a second semicircular edge plate, the first semicircular edge plate is fixedly connected to one end of the arc-shaped plate through the outer circumference thereof, and the second semicircular edge plate is fixedly connected to the other end of the arc-shaped plate through the outer circumference thereof; the infrared generator 37 is fixedly connected to the first semicircular side plate and the second semicircular side plate along the axial direction, so that the action points of the reflected infrared light on the tow bearing mechanism can be more concentrated, and the utilization efficiency of the infrared light emitted by the infrared generator 37 is improved.

The floating island type infrared drafting heat box further comprises flanges, and the flanges are fixedly connected to four edges of the radiation mechanism 36. In this case, the contact area between the radiation mechanism 36 and the tow support mechanism can be made larger by the flange, so that the sealing effect of the tow drafting space after the contact between the radiation mechanism 36 and the tow support mechanism is increased, and the energy loss of infrared light is reduced.

The floating island type infrared drafting heat box further comprises a sealing strip 23, and the sealing strip 23 is axially arranged between the flange and the tow bearing mechanism. In this case, the energy loss of the infrared light from the sealing tape 23 can be reduced by the sealing tape 23, thereby further reducing the energy loss of the infrared light.

Wherein the tow carrier comprises a solid body 15. A buffer space 44 is axially arranged in the body 15, and air inlets 39 are respectively arranged between the buffer space 44 and two axial side edges of the body 15, so that air generated by the fan 25 can enter the buffer space 44 through the air inlets 39; a plurality of air holes 43 are provided between the buffer space 44 and the upper surface of the body 15. In this case, after entering the interior of the buffer space 44 through the air inlet holes 39, the air generated by the fan 25 can be uniformly distributed to the air holes 43, so that the air can be uniformly distributed on the upper surface of the body 15, thereby ensuring that the tows to be treated loaded on the tow loading mechanism are uniformly heated.

Wherein, the two axial side edges of the body 15 are respectively provided with an air outlet 40. Under the condition, the gas blown into the space between the infrared radiation generating mechanism and the tow bearing mechanism can be timely led out through the gas outlet holes 40, the accumulation of local air pressure is prevented from being increased, and the working safety of the floating island type infrared drafting hot box provided by the embodiment of the invention is improved.

Wherein the air outlet 40 is inclined toward the air hole 43. In this case, the air blown into the space between the infrared radiation generating mechanism and the tow carrying mechanism can be timely led out through the air outlet holes 40, the path of the led-out air is optimized, the accumulation of local air pressure is avoided, and the working safety of the floating island type infrared drafting heat box provided by the embodiment of the invention is further improved.

The floating island type infrared drafting hot box also comprises an air inlet pipeline and an air return pipeline. The fan 25 is communicated with the air inlet 39 through an air inlet pipeline; the air outlet 40 is communicated with the fan 25 through an air return pipeline. In this case, the gas blown in from the blower 25 can be returned to the blower 25 through the return gas line, and since the returned gas has been heated by the thermal energy of the infrared rays in the space between the infrared radiation generating mechanism and the tow carrier mechanism, the temperature of the air blown out by the blower 25 can be increased by this circulation, so that the energy loss can be further reduced.

Wherein, the floating island type infrared drafting hot box also comprises an upper heat preservation shell 10. The infrared radiation generating mechanism is covered in the upper heat-insulating shell 10, and the bottom shape of the upper heat-insulating shell 10 is matched with the shape of the upper side of the infrared radiation generating mechanism. In this case, it is possible to reduce the loss of thermal energy of infrared rays through the infrared generating mechanism itself, thereby reducing energy loss.

Wherein the tow carrying mechanism further comprises a lower heat-insulating shell 14. The solid shell 15 is accommodated in the solid shell 15, and the top shape of the lower heat-preservation shell 10 is matched with the bottom shape of the solid body 15. In this case, it is possible to reduce the loss of thermal energy of infrared rays through the solid body 15, thereby further reducing energy loss.

In this embodiment, the lower heat-insulating shell 14 is provided with a first through hole 46 and a second through hole 48, and the air outlet 40 is communicated with the first through hole 46; the air inlet holes 39 communicate with the second through holes 48, thereby ensuring that the air blown by the fan 25 can smoothly enter the buffer space 44 through the air inlet holes 39.

Wherein, the floating island type infrared drafting hot box also comprises a stop block 47. The stop blocks 47 are arranged at two axial ends of the lower heat-preservation shell 14, third through holes 49 bent to 90 degrees are formed in the stop blocks 47, and the air inlet holes 39 are communicated with the second through holes 48 through the third through holes 49. In this case, it is ensured that the air blown out by the blower 25 can smoothly enter the buffer space 44 through the air inlet 39, which facilitates the difficulty in assembling the solid body 15 and the lower thermal insulation casing 14.

Wherein, the floating island type infrared drafting hot box also comprises a bracket 11. The inside of the bracket 11 has an accommodating space 24, and the fan 25 is disposed inside the accommodating space 24. In this case, the operation of the fan 15 can be enclosed in the inside of the bracket 11, and the influence of the operation of the fan 25 on the surrounding environment can be avoided.

The floating island type infrared drafting hot box further comprises a lifting mechanism 5, a first connecting piece 8, a second connecting piece 9, a third connecting piece 4, a limiting block 3 and a guide rod 2. The fixed end of the lifting mechanism 5 is fixedly connected to the support 11 through the second connecting piece 9, the moving end of the lifting mechanism 5 is fixedly connected to the infrared radiation generating mechanism through the first connecting piece 8, the third connecting piece 4 is fixedly connected to the infrared radiation generating mechanism, the limiting block 3 is fixedly connected to the support 11, one end of the guide rod 2 is fixedly connected to the third connecting piece 4, the other end of the guide rod 2 and the limiting block 3 form a moving pair, and the lifting direction of the lifting mechanism 5 is parallel to the direction of the guide rod 2. In this case, the infrared radiation generating mechanism can be driven by the lifting mechanism 5, thereby reducing human resources.

Wherein, the floating island type infrared drafting hot box also comprises a guide wire component. The yarn guiding assembly comprises a bearing part, a limiting column 19 and a yarn guiding part 20, the bearing part comprises a bearing surface 18 and a connecting surface 22, the bearing surface 18 is fixedly connected with the connecting surface 22, the bearing part is fixedly connected to two ends of the yarn bundle bearing mechanism through the connecting surface, and the bearing surface is flush with the bearing surface of the yarn bundle bearing mechanism; the wire guide piece 22 is provided with a plurality of wire guide grooves 21 along the axial direction of the wire bundle bearing mechanism; the limiting columns 19 are disposed at two ends of the bearing surface 18. In this case, the limiting column 19 can prevent the tows to be processed from being separated from the bearing surface 18, and the guide groove 21 can ensure that the tows to be processed smoothly pass through between the infrared radiation generating mechanism and the tow bearing mechanism.

Wherein, the bearing piece, the limiting column 19 and the wire guiding piece 20 are all made of ceramics. In this case, the ceramic can reduce the friction coefficient of the carrier, the limiting post 19 and the thread guide 20 itself, thereby further ensuring that the filament bundle to be treated smoothly passes between the infrared radiation generating mechanism and the filament bundle carrier mechanism.

Wherein the plurality of air holes 43 includes a first row of air holes 17 disposed along an axial center of the body 15 and a second row of air holes 16 disposed along a radial center of the body 15. In this case, since the air inlet holes 39 are located at two axial sides of the solid body 15, generally, the air volume at two axial sides of the buffer space 44 is large, and the second row of air holes 16 is arranged at the radial center of the solid body 15, so that the air volume at the radial center of the solid body 15 can be compensated, and the uniformity of the air volume of the tows to be processed on the bearing surface of the tow bearing mechanism can be further ensured, and the drafting quality of the processed tows can be further ensured.

The floating island type infrared drafting hot box further comprises a control terminal 13. The control terminal 13 is used for controlling the lifting action of the lifting mechanism 5 and the air valve opening degree of the fan 25. Firstly, the heating and air supply speed parameters are set through the control terminal 13, and the equipment is started. When the temperature reaches a set value, the functional button is pressed, the upper heat-insulating shell 14 and the infrared radiation generating mechanism are lifted by the lifting mechanism 5, fibers to be processed are respectively placed into the wire guiding assemblies at the fiber inlets, the fibers are guided to pass through the hot box from the upper part of the tow bearing mechanism and are discharged from the hot box from the corresponding wire guiding assembly at the fiber outlets, then the functional button is pressed, and the upper heat-insulating shell 14 and the infrared radiation generating mechanism are put down by the lifting mechanism 5 to be in close contact with the sealing strip 23. The position of the wire guide assembly is adjusted up and down, and meanwhile, the air speed of the floating island is adjusted by adjusting the opening of the air valve, so that the wires pass through the central line position in the heating wire channel. The filaments are always in a uniformly heated state during the time they pass through the heating filament path. By adjusting the process speed, the hot drawing and tension/relaxation heat setting of the fiber can be completed.

Wherein, the floating island type infrared drafting hot box also comprises a counterweight base 1. The counterweight base 1 is fixedly connected with the bottom of the support 11 to form a support seat 12 of the tow bearing mechanism. Under the condition, the state stability of the floating island type infrared drafting heat box provided by the embodiment of the invention in the working process can be ensured, and the probability of toppling is reduced.
