Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fiber filament production, in particular to a fiber filament heating and deforming device. Background Art
[0002] When glass fiber filaments are twisted at room temperature, the stability is poor. In order to ensure the twisting effect, the fiber filaments need to be twisted at a temperature higher than the glass transition temperature, so that the molecular chains are easily deformed under the action of external force, and the fiber filaments can obtain better deformability; in order to ensure twisting at the glass transition temperature, the fiber filaments need to be preheated before twisting.
[0003] In order to improve the preheating efficiency, the current method is to bundle a large number of single fiber filaments and then preheat them through a high-temperature heating device. Because the fiber filaments overlap each other in this preheating method, the fiber filaments are unevenly heated, which not only affects the twisting effect of the fiber filaments, but also causes the fiber filaments to stick to each other, resulting in broken filaments. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a fiber filament heating and deforming device, which separates each fiber filament for individual preheating, thereby avoiding the problem of uneven heating caused by the superposition of fiber filaments.
[0005] In order to achieve the above purpose, the utility model provides a fiber filament heating and deforming device, which includes a bottom plate and heating grooves arranged side by side on the bottom plate and extending along the length direction of the bottom plate; an installation groove with openings at the top and both ends is arranged along the length direction of the heating groove, and a heat conducting member and a heating device for heating the heat conducting member are installed in the installation groove; a wire channel for the fiber filament to slide back and forth is arranged on the heat conducting member; a wire inlet communicating the wire channel with the outside and for the fiber filament to be stuck into is arranged at the top of the heat conducting member.
[0006] After adopting the above structure, by threading the fiber filaments into different wire channels respectively, one fiber filament is threaded into one wire channel, so as to realize the isolation between the fiber filaments, avoid the superposition of the fiber filaments, and cause problems such as uneven heating or adhesion; by setting the wire inlet, it is convenient for the fiber filaments to be stuck in, and the wire threading efficiency is improved; when one of the fiber filaments breaks, quick repair can be realized, and the fiber filament in the wire channel can be re-threaded, improving the repair efficiency.
[0007] In order to limit the fiber filament and prevent it from easily slipping out of the wire channel, the width of the wire channel is greater than the width of the wire inlet.
[0008] In order to facilitate the guiding of the fiber filament and ensure that the fiber filament is smoothly threaded into the wire channel, guiding inclined surfaces are arranged on both side walls of the wire inlet.
[0009] To ensure the stability of the heating temperature, the heating device includes a heating tube wound around the outside of the heat conducting member. The heating tube passes through the heating groove and is connected to a heater through a circulation pipeline.
[0010] To reduce heat loss, the heating groove is made of heat insulation material.
[0011] To seal the top of the installation groove and further reduce heat loss, a cover plate for sealing the top of the installation groove is installed at the top of the installation groove.
[0012] To achieve the connection stability between the cover plate and the installation groove and at the same time reduce its sealing effect, a lock is provided between the cover plate and the installation groove.
[0013] To seal both ends of the installation groove and reduce heat loss, end covers for closing the openings at both ends of the installation groove are installed at both ends of the heating groove. Guide wire openings corresponding to the wire channels and the wire inlet are provided on the end covers.
[0014] To improve the preheating efficiency and reduce the volume of the device, two wire channels are arranged side by side on each heat conducting member.
[0015] After adopting the above technical solution, the beneficial effects of the present utility model are as follows:
[0016] A fiber filament heating and deforming device of the present utility model solves the technical problems of uneven preheating before fiber filament twisting and adhesion between fiber filaments in the prior art. The present utility model separately preheats each fiber filament, thereby ensuring the uniformity of heat received by the fiber filaments, and at the same time realizing the isolation of the fiber filaments, avoiding the adhesion problem caused by the stacking of fiber filaments.

Detailed Embodiments
[0022] The present utility model will be further described below in conjunction with the accompanying drawings.
[0023] All orientations mentioned in this specification are based on the orientation when a fiber filament heating and deforming device of the present utility model is operating normally, without limiting its orientation during storage and transportation, only representing relative positional relationships and not absolute positional relationships.
[0024] As Figure 1 、 Figure 2 and Figure 3 collectively shown, a fiber filament heating and deforming device includes a bottom plate 1 and a heating groove 2 installed side by side on the bottom plate 1 and extending along the length direction of the bottom plate 1; the heating groove 2 is detachably fixed on the bottom plate 1 by bolts.
[0025] An installation groove 21 with openings at the top and both ends is formed along the length direction of the heating groove 2; guide wire wheels (not shown in the figure) are installed at both ends of the installation groove 21; a heat conducting member 22 and a heating device 23 for heating the heat conducting member 22 are installed in the installation groove 21. A wire path 221 for the fiber filament to slide back and forth is formed on the heat conducting member 22; a wire inlet 222 communicating the wire path 221 with the outside and for the fiber filament to be caught in is arranged at the top of the heat conducting member 22.
[0026] In order to facilitate the fiber filament to smoothly penetrate into the wire path 221, guiding inclined surfaces 224 are arranged on both side walls of the wire inlet 222, and the guiding inclined surfaces 224 guide the fiber filament to facilitate the fiber filament to be caught in the wire inlet 222.
[0027] The heating device 23 includes a heating pipe 231 wound around the outside of the heat conducting member 22, and the heating pipe 231 passes through the heating groove 2 and is connected to a heater through a circulation pipeline 232. Ordinary heat conducting oil or diphenyl heat conducting oil can be used in the heating pipe 231, and this embodiment does not limit this.
[0028] When it is necessary to preheat the fiber filament, the fiber filament is caught in the wire path 221 from the wire inlet 222 at the top of the heating groove 2, and both ends of the fiber filament extend out from the openings at both ends of the installation groove 21, and the fiber filament is tensioned and guided by the guide wire wheels. The heating device 23 heats the heat conducting member 22 to increase the temperature in the wire path 221, thereby heating the fiber filament in the wire path 221 in real time, realizing the preheating of the fiber filament.
[0029] After the fiber filament is caught in the wire path 221 from the wire inlet 222, in order to prevent it from slipping out randomly, the width of the wire path 221 is greater than the width of the wire inlet 222.
[0030] As Figure 3 and Figure 4 collectively shown, in order to reduce heat dissipation in the heating groove 2 and reduce energy consumption, the present utility model has made three aspects of optimization:
[0031] 1. The heating tank 2 is made of heat-insulating materials, such as made of fiberglass materials or made of heat-insulating boards.
[0032] 2. At the top of the installation groove 21, a cover plate 25 for closing the top of the installation groove 21 is installed; the cover plate 25 is detachably installed on the heating tank 2, and a buckling method can be adopted. In this embodiment, for the convenience of opening and closing, one side of the cover plate 25 is hinged to one side of the heating tank 2, and then the cover plate 25 is buckled on the top of the installation groove 21 by the action of gravity, realizing the closure of the top of the installation groove 21. When threading the wire path 221 in the installation groove 21, just open the cover plate 25.
[0033] In order to achieve the tight buckling of the cover plate 25 and the installation groove 21 and increase its sealing performance, a locking mechanism is provided between the cover plate 25 and the installation groove 21. The locking mechanism can adopt the box cover locking mechanism in the prior art or an elastic snap structure, etc. As long as it can ensure that when the cover plate 25 is buckled, the cover plate 25 can be pressed tightly on the installation groove 21; when it needs to be opened, release the restriction of the locking mechanism, and the cover plate 25 can open the installation groove 21. This embodiment does not limit this.
[0034] 3. End caps 24 for closing the openings at both ends of the installation groove 21 are installed at both ends of the heating tank 2. Guide wire openings 241 corresponding to the wire path 221 and the wire inlet 222 are provided on the end caps 24. The end caps 24 close both ends of the installation groove 21, thereby reducing the heat loss rate; by providing the guide wire openings 241, it is avoided that when the fiber wire penetrates into the wire path 221, the end caps 24 cause interference.
[0035] Such as Figure 3 As shown, in order to increase the number of fiber wires preheated by the device under the premise of the same floor area, two wire paths 221 are arranged side by side on each heat conducting member 22; the two wire paths 221 share a set of heating device 23, thereby reducing the number of equipment inputs.
[0036] A fiber wire heating and deforming device of the present utility model solves the technical problems of uneven preheating before fiber wire twisting and mutual adhesion between fiber wires in the prior art. The present utility model preheats each fiber wire separately, thereby ensuring the uniformity of heat received by the fiber wires, and at the same time realizing the isolation of the fiber wires, avoiding the adhesion problem caused by the superposition of fiber wires.
[0037] Certainly, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present utility model should also belong to the protection scope of the present utility model.
