However, in the prior art, the uneven heating of nylon short fibers in the dispersion cylinder easily causes the problem of melting and deformation of nylon short fibers. Summary of the Utility Model

[0003] To overcome the defects existing in the prior art, a nylon short fiber dispersion device for nylon wheel production is provided to solve the problem that the uneven heating of nylon short fibers in the dispersion cylinder in the prior art easily causes the melting and deformation of nylon short fibers.

A material receiving mesh plate is in contact with the upper end surface of the ultrasonic generating device. The side end of the material receiving mesh plate is fixedly screwed to the upper surface of the ultrasonic vibrator through an adapter plate. A drain pipe is connected to the rear side end of the ultrasonic vibrator.

Detailed Embodiment

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Referring to Figures 1 to 4 As shown, the present invention provides a nylon short fiber dispersion device for nylon wheel production, including: a nylon fiber disperser 1 and a dispersion pair roller 3. The dispersion pair roller 3 is installed inside the nylon fiber disperser 1 through a rotating shaft 32.

[0020] An ultrasonic vibrator 2 is provided at the lower end of the nylon fiber disperser 1. An ultrasonic generating device 23 is arranged inside the lower end of the ultrasonic vibrator 2. The upper end surface of the ultrasonic generating device 23 contacts a material receiving mesh plate 21. The side end of the material receiving mesh plate 21 is screwed and fixed to the upper surface of the ultrasonic vibrator 2 through a connecting plate 22. A drain pipe 25 is connected to the rear side end of the ultrasonic vibrator 2. Spray racks 4 are welded to the front and rear inner walls of the nylon fiber disperser 1. Spray nozzles 42 are installed at the inclined surfaces of the spray racks 4.

[0021] When dispersing the nylon short fibers in the nylon wheel raw materials, first add the nylon short fibers into the nylon fiber disperser 1, so that the nylon short fibers are scattered by the dispersion columns 31 distributed alternately on the surface of the rotating dispersion pair roller 3 and then fall to the spray rack 4. At this time, the spray nozzles 42 spray the dispersion liquid into the nylon short fibers. The excess liquid and the nylon short fibers after spraying fall into the ultrasonic vibrator 2. Ultrasonic waves are generated by the ultrasonic generating device 23 in the ultrasonic vibrator 2. When the ultrasonic waves propagate in the medium, high-frequency vibrations will be generated, generating shear force and pressure force, so that the fibers collide and rub against each other, thereby realizing the dispersion of the fibers. After dispersion, open the control valve 24 and continue to vibrate to separate and discharge the liquid in the nylon short fibers. Take out the well-dispersed nylon short fibers to prepare the mixture ratio of the nylon wheel raw materials.

[0022] In this embodiment, a stepping motor 11 is fixed to the left side end of the nylon fiber disperser 1; and the stepping motor 11 is connected to the rotating shaft 32, and a transmission assembly 12 is installed on the surface of the rotating shaft 32. A feed inlet 13 is provided on the upper end surface of the nylon fiber disperser 1, and a discharge outlet 15 is provided on the lower end surface of the nylon fiber disperser 1. Dispersion columns 31 are welded equidistantly on the roller surface of the dispersion pair roller 3.

[0023] As a preferred embodiment, the stepping motor 11 drives the two rotating shafts 32 to rotate through the transmission assembly 12, so that the dispersion columns 31 distributed alternately on the surface of the rotating dispersion pair roller 3 disperse the incoming nylon short fibers.

[0024] In this embodiment, a small blower 16 is installed on the upper surface of the nylon fiber disperser 1. The small blower 16 is connected to an exhaust air net opening 14 through an air supply pipe 17; and the exhaust air net openings 14 are symmetrically distributed on the front and rear sides of the dispersing counter-rolls 3.

[0025] As a preferred implementation manner, the small blower 16 blows air to the exhaust air net opening 14, so that the fibers remaining on the inner side of the exhaust air net opening 14 and the surface of the dispersing counter-rolls 3 are discharged downward, facilitating the nylon fiber disperser 1 to discharge materials cleanly.

[0026] In this embodiment, a liquid guiding cavity 43 is arranged inside the spray rack 4. The right end of the spray rack 4 is connected to an infusion pipe 41; and the infusion pipe 41 is connected to a spray head 42 through the liquid guiding cavity 43.

[0027] As a preferred implementation manner, the infusion pipe 41 conveys the dispersion liquid of the nylon staple fibers to the spray head 42 through the liquid guiding cavity 43 and sprays it, spraying the dispersion liquid on the nylon staple fibers dispersed by the dispersing counter-rolls 3, making the nylon staple fibers more evenly dispersed.

[0028] In this embodiment, connection plates 22 are welded to the left and right side edges of the upper surface of the material holding mesh plate 21, and a control valve 24 is installed on the surface of the drain pipe 25. The ultrasonic vibrator 2, the material holding mesh plate 21, the ultrasonic generating device 23, and the drain pipe 25 constitute a vibratory dispersion mechanism.

[0029] As a preferred implementation manner, by removing the nuts at the connection plates 22, the material holding mesh plate 21 can be lifted upward, facilitating the removal of the dispersed nylon staple fibers. While the vibratory dispersion mechanism facilitates the further dispersion of the nylon staple fibers, it effectively drains the nylon staple fibers, avoiding the phenomenon of melting and deformation of the nylon staple fibers during hot air drying, and optimizing the ratio of the raw materials for nylon wheel production.

[0030] The nylon staple fiber dispersion device for nylon wheel production of the present utility model can effectively solve the problem that the nylon staple fibers in the dispersion cylinder are prone to melting and deformation due to uneven heating in the prior art, facilitating the more sufficient and uniform dispersion of the nylon staple fibers, effectively draining the nylon staple fibers, avoiding the phenomenon of melting and deformation of the nylon staple fibers during hot air drying, optimizing the ratio of the raw materials for nylon wheel production, and being applicable to the nylon staple fiber dispersion device for nylon wheel production.

[0031] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
