Description

Technical Field

[0001] The utility model relates to the technical field of fiber preparation, in particular to spinning feeding equipment for preparing modified biomass fibers. Background Art

[0002] Electrospinning technology is also referred to as electrospinning technology. This technology introduces electrostatic force and stretches the polymer fluid to make the polymer fiber diameter reach the micro-nano scale. The polymer solution or melt is placed in a strong electrostatic field. When no electric field is applied, the solution or melt is affected by surface tension and gravity and is spherical at the end of the capillary. When the electric field is weak, the electrostatic repulsion is less than the liquid surface tension, and the droplet at the end of the capillary still maintains a spherical shape. When the power supply voltage gradually increases, the electrostatic repulsion also gradually increases, and the spherical droplet is gradually stretched into a cone. When the power supply voltage is equal to the critical voltage, the electrostatic repulsion is balanced with the liquid surface tension, and a cone is formed at the end of the capillary. When the power supply voltage continues to increase, the electrostatic repulsion will be greater than the liquid surface tension, and the liquid jet will be ejected from the end of the Taylor cone and fly to the collecting plate at high speed, thus forming nanofibers. Electrospinning is based on this principle.

[0003] In the current process of limited electrospinning of modified biomass, the process of spraying liquid by the nozzle used to feed the material can only be carried out under a fixed raw material pressure, and the flow rate of the nozzle cannot be automatically adjusted. When spinning with different raw material pressures, the nozzle needs to be replaced, which seriously limits the work efficiency. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figure 1 and Figure 3As shown, in this embodiment, a spinning feeding device for preparing modified biomass fibers includes a mounting plate 1, characterized in that: a replacement component 4 is installed on the mounting plate 1, and the replacement component 4 includes a driven gear 401 rotatably connected to one side of the bottom outer wall of the mounting plate 1, and four through holes 402 distributed at equal distances are opened inside the driven gear 401, and a protrusion 403 is arranged on the outer wall at one end of the mounting plate 1, and a motor 405 is fixedly installed on the top outer wall of the protrusion 403, and a transmission gear 404 meshing with the driven gear 401 is rotatably connected to the bottom outer wall of the protrusion 403, and the number of protruding teeth of the driven gear 401 is four times the number of protruding teeth of the transmission gear 404, and the rotating shaft of the motor 405 and the transmission gear 404 are coaxially fixed.

[0023] A feed pipe 2 is fixedly inserted into the top outer wall of the mounting plate 1 , and the feed pipe 2 can be connected to the multiple through holes 402 .

[0024] When replacing a raw material, it is only necessary to start the motor 405. The motor 405 drives the transmission gear 404 to rotate one or more circles. The transmission gear 404 drives the driven gear 401 to rotate at the bottom of the mounting plate 1 through meshing, and then a feeding component 5 at the bottom of the driven gear 401 will also move to the bottom of the feed pipe 2. At this time, the raw material passes through the through hole 402 into the feeding component 5 and then sprays out to start working.

[0025] like Figure 2 and Figure 4 As shown, a plurality of feeding assemblies 5 are installed at the bottom of the driven gear 401. The feeding assemblies 5 include four connecting tubes 501 fixedly connected to the outer wall of the bottom of the driven gear 401. The four connecting tubes 501 are respectively connected to the four through holes 402. A spinning nozzle 3 is slidably inserted inside the four connecting tubes 501. The specifications of the four spinning nozzles 3 are different.

[0026] Two protrusions 502 are arranged at the bottom of the circumferential outer wall of the spinning nozzle 3, and two extension rings corresponding to the two protrusions 502 are arranged at the bottom of the circumferential outer wall of the connecting tube 501. A screw rod 503 is rotatably connected to the top outer wall of one of the protrusions 502, and the screw rod 503 is threadedly connected to one of the extension rings. A limiting rod 504 is fixedly connected to the top outer wall of the other protrusion 502, and the limiting rod 504 is slidably inserted into the other extension ring.

[0027] A second motor 505 is fixedly mounted on the outer wall of the bottom of one of the second protrusions 502 , and the rotating shaft of the second motor 505 and one end of the screw rod 503 are coaxially fixed.

[0028] When the height of the spinning nozzle 3 needs to be adjusted due to different materials and voltage, it is only necessary to start the motor 2 505 at the corresponding position. The motor 2 505 drives the screw rod 503 to rotate. The connecting tube 501 restricted by the screw rod 503 and the limit rod 504 cannot rotate. Therefore, the screw rod 503 can drive the connecting tube 501 to be adjusted at will in the vertical direction.

[0029] like Figure 1 and Figure 2 As shown, the lead angle of the thread lines of the circumferential outer wall of the plurality of screw rods 503 is smaller than the equivalent friction angle, so that the screw rods 503 have a self-locking property, and thus the position of the spinning nozzle 3 will not change randomly after the position adjustment is completed.

[0030] The utility model provides a spinning feeding device for preparing modified biomass fibers, and the specific working principle is as follows:

[0031] When the device is working, when changing a raw material, it is only necessary to start the motor 405, and the motor 405 drives the transmission gear 404 to rotate one or more circles. The transmission gear 404 drives the driven gear 401 to rotate at the bottom of the mounting plate 1 through meshing, and then a feeding assembly 5 at the bottom of the driven gear 401 will also move to the bottom of the feeding pipe 2. At this time, the raw material passes through the through hole 402 into the feeding assembly 5 and then sprays out to start working. When the height of the spinning nozzle 3 needs to be adjusted due to different materials and voltage, it is only necessary to start the motor 2 505 at the corresponding position. The motor 2 505 drives the screw rod 503 to rotate. The connecting tube 501 restricted by the screw rod 503 and the limit rod 504 cannot rotate, so the screw rod 503 can drive the connecting tube 501 to be adjusted in the vertical direction at will.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
