Description
Technical Field
The invention belongs to the field of fiber material processing, and particularly relates to a portable hand-held chemical fiber hot knife device.
Background
The ultra-high molecular weight polyethylene fiber is the fiber material with the highest specific strength in the industrialized fiber materials at present, and is one of three high-performance fibers in the world. Owing to the ultrahigh molecular weight and narrower molecular weight distribution of UHMWPE, the UHMWPE fiber material has excellent mechanical property, wear resistance and chemical corrosion resistance, and simultaneously has the characteristics of light weight, high heat conductivity coefficient and the like, so that the UHMWPE fiber material has wide application in the fields of national defense and military, aerospace, ocean engineering and civil protection.
In the UHMWPE fiber production process, the fiber needs to be subjected to multi-stage hot stretching to improve the fiber strength. In the drawing process, the filaments are inevitably broken and wound around the drawing rolls. When the fiber is wound on the roll surface more, the normal production can be affected, and even shutdown treatment is needed when serious. In general, it is necessary to cut and remove the wound wire on the roll surface by using a cutter such as a hook cutter or a knot cutter, and in actual production, when the winding amount is large, the fiber strength is high, and it is difficult for the cutter to cut all the fibers. And the roller rotates and can not be fixed at the same position to cut all the fibers and take down, so that the treatment difficulty is high. When serious, the machine must be stopped and cleaned, which affects the normal operation of production.
The UHMWPE fiber has high strength, and the cutter is extremely easy to wear in the treatment process, so that the cutter consumption of the production line is large, after the cutter is aged and dulled, the cutter can not be completely cut off and can be rolled into the drawing roller, so that the hand of a person is cut, and the cutter has great potential safety hazard.
The traditional hot knife only heats the head of the current knife, but because the roller surface rotates, the same position of the fiber on the drawing roller can not be cut when the fiber is cut, the cutting surface is an arc line, the heat dissipation of the hot knife is fast, the time is required for reheating, the fiber is difficult to be taken down fast, and the problem of mass filament winding treatment in the production at the present stage can not be well solved.

Detailed Description
The invention will now be described in detail with reference to the drawings and specific examples. Features such as a part model, a material name, a connection structure, a control method, an algorithm and the like which are not explicitly described in the technical scheme are all regarded as common technical features disclosed in the prior art.
The hand-held chemical fiber cutting device comprises a holding handle 1, a rotating shaft 2, a rotating roller 3, a hot knife 4, a power supply 5 and the like, and is shown in figure 1.
The portable hand-held chemical fiber hot knife device in the technical scheme comprises a holding handle 1, a rotary roller 3 and a hot knife 4, wherein the hand-held chemical fiber hot knife device is specifically shown in fig. 1.
The rotary roller 3 is a passive rotary roller, one end of the rotary shaft 2 is connected with a bearing arranged in the handle 1, the rotary roller 3 is driven by the production drafting roller 9 to rotate through friction force, a first on-off switch is arranged between the power supply and the hot knife 4, the handle 1 is provided with a push switch 6, and the push switch 6 is in contact linkage with the first on-off switch; the roller surfaces at the two ends of the rotary roller 3 are provided with transmission parts with larger friction force, namely friction contact surfaces 7, and materials with rough surfaces such as rubber, plastic, frosted metal, frosted glass and the like can be used.
The hot knife 4 is fixed on the surface of the rotary roller 3, the length direction of the hot knife 4 is parallel to the axis of the rotary roller 3, and the rotation direction of the rotary roller 3 is opposite to the rotation direction of the production drafting roller 9. The roller 3 is provided with a slit parallel to the axis of the roller 3. The hot knife 4 is inlaid in the slit. The hot knife 4 is self-heating, and a resistance heater is arranged inside the hot knife 4. The length of the hot knife 4 is not more than the length of the roll surface, and the width is not more than 1/2 of the circumference of the roll surface.
The diameter of the production draft roller 9 is an integer multiple of the diameter of the rotor roller 3. The hot knife 4 is provided with one or more on the rotating roll 3 and makes the cutting point position of one hot knife 4 on the production drafting roll 9 the same, see fig. 2.
The portable hand-held chemical fiber hot knife device further comprises a power supply arranged in the holding handle 1, the power supply is electrically connected with the hot knife, the wiring end of the hot knife 4 is connected with the power supply on the handle through an electric slip ring, and the heating and stopping of the hot knife are controlled through a switch on the handle. The power supply is a storage battery, and can also be directly connected with the power supply in the device through the quick connector by an external power supply to realize power supply. The heating temperature of the hot knife 4 is 90-1000 ℃, and the specific implementation proposal is that the heating temperature is not lower than 600 ℃.
The hot knife 4 inlaid on the surface of the rotary roller is heated, so that the hot knife 4 is in a red hot state, and the fiber bundles can be fused at the moment of contacting the fibers, thereby achieving the purpose of cutting.
In the implementation, in a production system with the diameter of the drafting roller being 30cm, the diameter of the rotating roller of the device is 15cm, namely the perimeter ratio is 2:1, when the surfaces of the drafting roller and the rotating roller are jointed and jointly rotate, the drafting roller rotates for one circle, and the rotating roller of the device rotates for two circles.
The operator firstly holds the handle to attach the rotary roller 3 to the surface of the drafting roller with filament winding, so that the passive rotary roller rotates along with the drafting roller, the rotating speeds of the two rotary rollers are synchronous, and the rotating directions are opposite. A certain pressure is applied to the rotating roller 3, so that the rotating roller 3 can be tightly attached to the fiber and compacted.
The heating switch on the handle is then turned on, and the hot knife 4 starts to heat. When the red hot blade rotates to a position tangential to the fiber, the hot blade contacts the fiber and fuses all the contacted fiber, the hot blade continues to rotate, when the next circle is tangential to the fiber, the fiber on the opposite side of the last tangent point is fused, the hot blade 4 further rotates, after the hot blade continues to rotate for one circle, the hot blade completely coincides with the first cutting point, and the residual fiber is completely cut through. By repeating this process, the fibers are cut into short bundles, and are not entangled with each other, and all the fibers wound around the roll can be easily removed.
The operator can also turn off the power supply after the first cut by controlling the heating switch on the handle, and turn on the power supply again when the hot knife 4 rotates to the second turn, so that the cutting point of each hot knife coincides with the same position, and in doing so, the fiber on the drawing roll will have only one break point.
Therefore, the user can select the perimeter ratio of the transfer roller 3 to the production drafting roller 9 according to the requirement and the actual size of the production line, or increase the number of the heating cutters, or manually control the heating start and stop by an operator so as to achieve the purpose of controlling the number of the actual tangential points.
In the implementation process, 1-2 tangent points basically can meet the processing requirement, and the more the tangent points are, the easier the removal is. It should be noted, however, that when the number of tangents is too large, the cutting efficiency will be reduced and the fibers will be too much cut into shorter bundles of small fibers, which tend to drift down to affect collection, and that in practice a number of tangents of greater than 4 is not recommended.
It should be noted that the components in the figures may be shown exaggerated for illustrative purposes and are not necessarily to scale. In the drawings, identical or functionally identical components are provided with the same reference numerals.

The heating unit is fixed inside the rotating roller 3, and the embedded side of the hot knife 4 is abutted with the heating unit, so that the hot knife 4 and the heating unit form contact heat transfer connection.
