[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The present invention provides Figure 1-Figure 11 A fiber product with shape memory function is shown, which is made of fiber raw material and hot melt adhesive raw material. After the hot melt adhesive raw material is mixed with the fiber raw material in an appropriate proportion, the brightness of the manufactured fiber filament 14 can be increased, and the color is transparent, and the original color of the fiber raw material has no effect; further, based on the adhesion characteristics of the hot melt adhesive, the elasticity and plasticity of the fiber filament 14 can be increased, so that the fiber filament 14 can be easily shaped in a heated state, and has a certain shape memory function.

[0039] The present invention also discloses a process for preparing a fiber product with shape memory function, which is used for preparing the fiber product with shape memory function. The specific process comprises the following steps:

[0040] Step 1: Prepare raw materials, prepare fiber raw materials, crush the fiber raw materials into flakes for later use, prepare hot melt adhesive raw materials, crush the hot melt adhesive into flakes for later use, which can ensure that the raw materials are fully melted, reduce the phenomenon that air is easily entrained in the molten material during the melting process of large pieces of raw materials, and increase the quality of the subsequent production of fiber filaments 14;

[0041] Step 2: Cleaning and drying the raw materials. The sheet-shaped fiber raw materials and sheet-shaped hot melt adhesive prepared in the first step are cleaned and dried for later use. Cleaning and drying the raw materials can reduce the impurity particles in the fiber filaments 14, so that the fiber filaments 14 have a uniform thermal expansion coefficient as a whole, so that they will not be cracked or broken during the cold and hot conversion.

[0042] The third step: preparing fiber filaments, mixing the sheet fiber raw material and the sheet hot melt adhesive in a weight ratio of 4.1:0.9 to form a production raw material, and the production raw material is put into a molding machine for processing and molding to prepare a filament structure; when preparing the fiber filament 14, the amount of sheet hot melt adhesive is small, which does not affect the main material performance of the fiber filament 14, and the small amount of fiber filament 14 fully increases the elasticity and plasticity of the fiber filament 14, so that the fiber filament 14 has good elasticity at room temperature and can be plastically deformed at high temperature, thereby being shaped to change its shape, such as: straight state, winding state, etc., which is particularly suitable for making wigs.

[0043] In order to produce the fiber filament 14 in the present invention, a molding machine is independently manufactured. The specific structure of the molding machine includes a molding machine body 1, and the molding machine body 1 is provided with a feeding hopper and a stirring device for supplying raw materials into the molding machine body 1. The feeding hopper and the stirring device are both existing common technologies and will not be described here.

[0044] The molding machine body 1 has a melting chamber 2 for raw materials to enter, and a heating chamber 3 is arranged on the periphery of the lower end of the melting chamber 2. The heat generated in the heating chamber 3 is transferred to the melting chamber 2 to melt the raw materials. A wire outlet mechanism is arranged at the bottom of the melting chamber 2, and the molten raw materials are discharged from the wire outlet mechanism to form a filamentary structure.

[0045] Among them, the wire-out mechanism includes a wire-out plate 10, which is fixedly arranged in the middle position of the bottom of the molding machine body 1. The wire-out plate 10 is provided with a wire-out hole 13 connected to the inside of the melting chamber 2. After the production raw materials in the melting chamber 2 are melted, they can be extruded from the wire-out hole 13 to form fiber filaments 14. The specific extrusion method and process will not be elaborated here.

[0046] In actual use, a plurality of wire outlet holes 13 are arranged side by side on the wire outlet plate 10, the wire outlet holes 13 are circular holes, and the cross-section of the extruded fiber filaments 14 is circular; at the same time, in actual use, the wire outlet plate 10 can also be detachably arranged in the middle position at the bottom of the molding machine body 1, so as to facilitate the adjustment of the wire outlet plate 10 of appropriate specifications according to the diameter requirements of the fiber filaments 14.

[0047] In order to facilitate the collection of fiber filaments 14 in the present invention, a side support plate 7 is provided on one side of the forming machine body 1, and a winding mechanism 8 for winding and storing the filamentary structure is provided on the side support plate 7. Multiple fiber filaments 14 can be wound on the winding mechanism 8 at the same time, which is convenient and practical. When in use, they can be cut according to the actual required length.

[0048] The winding mechanism 8 includes a rotating shaft 29, a fixed roller 28 and an air bag 30 arranged from the inside to the outside, a fiber filament containing tube 31 is sleeved on the outer circle of the air bag 30, and the filamentary structure is wound around the outer circle of the fiber filament containing tube 31. A motor 41 for driving the rotating shaft 29 to rotate is fixedly installed on the side of one of the side support plates 7, and the end of the rotating shaft 29 away from the motor 41 is rotatably arranged on the other side support plate 7; when working, the fiber filament containing tube 31 is sleeved on the outer circle of the air bag 30, and the motor 41 is started. The motor 41 drives the rotating shaft 29, the fixed roller 28, the air bag 30 and the fiber filament containing tube 31 to rotate through the rotating shaft, so that the fiber filament 14 is wound around the outer circle of the fiber filament containing tube 31.

[0049] Furthermore, since air can be inflated and sucked into the interior of the airbag 30, the fiber thread holding tube 31 can be conveniently mounted and fixed on the outer circle of the airbag 30, and can be conveniently taken out.

[0050] During specific operation, the gas in the airbag 30 is extracted, and the airbag 30 shrinks and deforms, so that the fiber yarn containing tube 31 can be smoothly separated from the outer circle of the airbag 30. When the airbag 30 is inflated, the airbag 30 expands and deforms, so that the fiber yarn containing tube 31 can be quickly tightened and fixed, which is convenient to use.

[0051] There are two side support plates 7, and the winding mechanism 8 is arranged between the two side support plates 7. The two side support plates 7 are detachably arranged. When the two side support plates 7 are separated, the fiber yarn containing drum 31 can be conveniently loaded and unloaded. In actual use, a moving wheel with a wheel brake can be installed at the bottom of the side support plate 7 to facilitate movement and positioning. An electric push rod, an electric cylinder and other mechanisms can also be arranged between the two side support plates 7 to control the distance between the two side support plates 7 for adjustment. The specific implementation method will not be repeated here.

[0052] Taking into account that the fiber filaments 14 have a certain amount of heat when they are just extruded from the filament outlet hole 13, when the fiber filaments 14 are immediately wrapped around the outer circle of the fiber filament containing tube 31, adjacent fiber filaments 14 are easy to stick to each other. Therefore, a heat dissipation mechanism 9 for blowing air to cool the filamentary structure is provided on the side of the side support plate 7 close to the molding machine body 1. The heat dissipation mechanism 9 can blow air to dissipate the surface of the fiber filaments 14, so that the heat dissipation mechanism 9 can be cooled quickly.

[0053] The heat dissipation mechanism 9 is provided with two groups, and the two groups of heat dissipation mechanisms 9 are arranged up and down; the heat dissipation mechanism 9 includes a wind plate 37, a connecting pipe 40 is arranged at the upper end of the wind plate 37, and a wind cavity 38 is arranged inside the wind plate 37, one end of the wind cavity 38 passes through the side of the wind plate 37 away from the side support plate 7, and the connecting pipe 40 is connected to the wind cavity 38. A positioning support plate 35 is installed on the side of the side support plate 7, and a third electric push rod 36 is fixedly connected to the positioning support plate 35, and one end of the third electric push rod 36 away from the positioning support plate 35 is fixedly connected to the wind plate 37; when working, the third electric push rod 36 pushes the wind plates 37 to move, firstly moving the two wind plates 37 away from each other so that the fiber filaments 14 pass between the two wind plates 37 and are wound around the outer ring of the fiber filament containing tube 31; then, the two wind plates 37 are brought close to each other and fit on the upper and lower sides of the fiber filaments 14, and the wind force blown out from the opening of the wind cavity 38 inside the wind plates 37 can be blown along the upper and lower surfaces of the fiber filaments 14 to dissipate heat, thus avoiding the phenomenon that the thinner fiber filaments 14 are easily stretched again due to the direct blowing wind force, thereby ensuring the heat dissipation and avoiding the fiber filaments 14 from being stretched again.

[0054] It should be noted that, since the diameter of the cross section of the fiber filament 14 is relatively small, the fiber filament 14 can be dried quickly even if the wind passes through the upper and lower parts of the fiber filament 14 in parallel.

[0055] Furthermore, a wave surface 39 is provided on each side of the two wind cavities 38 that are close to each other. The wind force discharged from the opening of the wind cavity 38 can be transmitted in a wave-like manner through the guidance of the wave surface 39, thereby forming a wave-like wind flow above and below the fiber filaments 14, driving the fiber filaments 14 to swing in a wave-like manner with a certain amplitude, thereby increasing the heat dissipation efficiency of the fiber filaments 14 and removing some dust that is easily adsorbed on the surface of the fiber filaments 14.

[0056] Furthermore, based on the wave-like wind flow driving the fiber filaments 14 to swing in a wave-like manner, the swing amplitude of the fiber filaments 14 will not be too high. Therefore, the fiber filaments 14 have limited stretching capacity and will not become thinner again. In actual operation, a fiber filament 14 greater than the straight-line distance between the wire outlet hole 13 and the winding mechanism 8 is left, so that the fiber filament 14 is not easily broken by excessive tension when the winding mechanism 8 is wound up, and the fiber filament 14 exceeding the straight-line distance between the wire outlet hole 13 and the winding mechanism 8 is controlled within a reasonable length range. Based on the swinging effect on the fiber filaments 14, the fiber filaments 14 can also be well transported and guided without being entangled with each other.

[0057] A wind pump body fixing plate 34 is arranged on the side of one of the side support plates 7, and a wind pump body 32 is fixedly installed on the wind pump body fixing plate 34. A four-way joint 33 is arranged on the wind pump body 32, and the four-way joint 33 is respectively connected with the two hoses 27 and the interior of the airbag 30, and one end of the two hoses 27 away from the four-way joint 33 is respectively connected with two connecting pipes 40, and the air outlet at the wind cavity 38 and the air inlet and outlet of the airbag 30 are provided by the wind pump body fixing plate 34, which is practical and convenient.

[0058] Taking into account that when the heat dissipation mechanism 9 dissipates heat for the fiber filaments 14, the heat is blown back to the position of the wire outlet hole 13, therefore, a circle of annular cylinder 4 is fixedly provided at the outer ring of the molding machine body 1, and the annular cylinder 4 surrounds the outer ring of the heating chamber 3. An insulating plate 23 for reducing the heat transfer from the inside of the annular cylinder 4 to the outside is fixedly provided on the inner outer ring wall of the annular cylinder 4, and a spiral structure 24 is fixedly provided on the inner inner ring wall of the annular cylinder 4. An air inlet scoop 5 is provided at the lower end of the annular cylinder 4 close to the side support plate 7, and an air outlet scoop 6 connected to the inside of the annular cylinder 4 is provided at the upper end of the annular cylinder 4 away from the side support plate 7; the air inlet scoop 5 can collect the waste heat gas blown back when the heat dissipation mechanism 9 dissipates heat for the fiber filaments 14, and the waste heat gas enters the inside of the annular cylinder 4 and flows in a spiral shape along the spiral structure 24, thereby keeping the surrounding of the heating chamber 3 warm, making full use of the waste heat, and reducing the power consumption of the heating element inside the heating chamber 3.

[0059] In order to ensure that more waste heat gas enters the interior of the annular cylinder 4 from the air inlet scoop 5, a one-way valve 25 and a suction pump 26 are provided at one end of the air inlet scoop 5 connected to the interior of the annular cylinder 4. When the suction pump 26 is turned on, a certain suction force is generated, thereby guiding the waste heat gas to enter the annular cylinder 4. The suction pump 26 only needs to use a low-power suction pump, saving energy. After the waste heat gas circulates through the interior of the annular cylinder 4, it is discharged from the air outlet scoop 6.

[0060] In order to further avoid the phenomenon of mutual entanglement between multiple fiber filaments 14, a fixed guide member 11 is provided on the bottom surface of the wire outlet plate 10, and two movable guide members 12 are provided on the bottom surface of the forming machine body 1. The fixed guide member 11 and the movable guide member 12 both have a guiding effect on the fiber filaments 14. The fixed guide member 11 includes a fixed support plate 15 and a fixed guide wheel 16. The fixed support plate 15 is fixedly welded to the bottom surface of the wire outlet plate 10, and the fixed guide wheel 16 is rotatably arranged on the fixed support plate 15. The movable guide member 12 includes a movable support plate 21 and a movable guide wheel 22. The movable guide wheel 22 is rotatably arranged on the movable support plate 21. The upper end of the movable support plate 21 is fixedly connected to a second electric push rod 20, and the end of the second electric push rod 20 away from the movable support plate 21 is provided with a connecting seat 19. A base plate 17 is fixedly provided on the bottom surface of the molding machine body 1, and a horizontally arranged first electric push rod 18 is fixedly installed on the base plate 17. The end of the first electric push rod 18 away from the base plate 17 is fixedly connected to the side surface of the connecting seat 19, and the wire is output from the wire outlet hole 13 to form a fiber filament 14. The fiber filament 14 is distributed along the bottom surface of the fixed guide wheel 16 and the upper surface or bottom surface of the corresponding movable guide wheel 22 in sequence, and the fiber filament 14 is finally wound on the winding mechanism 8; when working, the second electric push rod 20 pushes the movable support plate 21 to move, and can also adjust the height position of the movable guide wheel 22, so as to achieve further guiding and limiting of the fiber filament 14; the fiber filament 14 can also be tightened according to actual needs to avoid the situation in which the fiber filament 14 is loose and entangled in an accidental situation, thereby increasing production costs.

[0061] In specific implementation: a size sensor or position sensor for monitoring the length and position of the fiber filament 14 can be set on the molding machine body 1. When it is detected that the position or length of the fiber filament 14 exceeds the set threshold, the second electric push rod 20 can be turned on to adjust the position of the movable guide wheel 22, and the fiber filament 14 with excess length can be tightened accordingly.

[0062] It should also be noted that when the first electric push rod 18 in the present invention is started, the horizontal distance of the movable guide wheel 22 can be adjusted, thereby adjusting the position of the movable guide wheel 22 to fit the fiber filament 14 according to actual needs; further, when the first electric push rod 18 drives the movable guide wheel 22 to move reciprocatingly horizontally, it can also achieve the purpose of combing and guiding the fiber filament 14.
