[0017] The beneficial effects of the present invention compared with the prior art are as follows:

[0018] 1. By opening the plug cap and using the introduction pipe to introduce the fiber liquid, the addition of the fiber liquid can be conveniently carried out. Reinstalling the plug cap for sealing can prevent the leakage of the fiber liquid during subsequent operations, keep the internal environment of the equipment clean and stable. The start of the pressurizing motor causes the rotation of the reciprocating lead screw, and the internal pressure is adjusted by the movement of the pressurizing piston block. Intermittent pressure is generated in the receiving cavity to provide power for the spinning of the fiber liquid. The spinning holes on the spinneret plate ensure the uniform ejection of the fiber liquid, forming continuous fiber filaments. The role of the cooling mechanism is to quickly cool the ejected fiber filaments to achieve an immediate shaping effect. The cooling process helps to improve the strength and durability of the fiber filaments, while reducing thermal stress and shrinkage, and improving the overall processing quality.

[0019] 2. The one-way valve can prevent the gas from flowing back to the filtering cavity when the pressurizing piston block moves downward, thus ensuring the correct direction of gas flow. The rotation of the pressurizing rotating shaft drives the movement of the gear, the passive gear, the linkage rotating shaft and the linkage swing rod, so that the linkage telescopic rod and the cleaning plate can slide reciprocally, thereby realizing the automatic cleaning of the filter screen, avoiding the blockage problem of the filter screen caused by dust accumulation, keeping the filter screen unobstructed, and improving the gas circulation effect.

[0020]

[0021] ​3. Cooling gas is generated by a cooling air pump, and the cooling gas enters the annular cooling groove through the cooling connecting pipe and the cooling groove, so that part of the gas flows directly downward through the cooling vertical hole, and the other part of the gas flows out obliquely downward through the cooling inclined hole. The cooling gas flowing out obliquely downward can make the fiber filaments cool and shape while tilting away from the central axis of the spinneret. The gas flowing directly downward can take away the heat of the inclined fiber filaments, so that the fiber filaments are evenly cooled, which helps to maintain consistent physical properties and quality of the fiber filaments during the shaping process. The cooling gas flowing out of the cooling inclined hole performs preliminary cooling and shaping on the fiber filaments, and the cooling gas flowing out of the cooling vertical hole further cools and shapes the fiber filaments, which more effectively reduces the temperature of the fiber filaments and increases the cooling rate, thereby better fixing the shape and performance of the fiber filaments.

[0022] 4. By adjusting the toggle arc rod, the rotation of the adjusting ring block is controlled, and then the rotation of the first shielding arc block is driven, so that the top of the spinneret hole can be exposed. The adjusting ring block also drives the rotation of the passive ring block by connecting the arc rod, so as to further adjust the position of the second shielding arc block, and control the opening and closing state of the corresponding bottom of the spinneret hole and the cooling inclined hole. By opening more spinneret holes, the number of fiber liquid sprayed can be increased, thereby improving production efficiency. By controlling the opening and closing of the cooling inclined hole, the cooling and shaping of the fiber filaments can be effectively assisted, ensuring that the fiber filaments maintain a stable cooling effect during the process of increasing the number of moldings, and comprehensively adjusting the fiber liquid spraying and cooling.

[0023] 5. When the number of spinneret holes opened is small, the length of the fiber filament formed at a single time is long, the number of cooling inclined holes opened is small, and the cooling gas flowing out of the cooling vertical holes can cover a longer distance. When the number of spinneret holes opened is large, the length of the fiber filament formed at a single time is short, the number of cooling inclined holes opened is large, and the cooling gas flowing out of the cooling vertical holes can cover a longer distance. Both can better adapt to the length of the fiber filament formed at a single time. As the number of spinneret holes increases or decreases, the cooling gas can be better utilized, and the flow and distribution of the cooling gas can be adjusted to adapt to new production conditions, thereby improving the utilization efficiency of the cooling gas and reducing energy waste.

Then, the pressurizing motor 22 is started. The pressurizing motor 22 can drive the reciprocating lead screw 24 to rotate. The reciprocating rotation of the reciprocating lead screw 24 can drive the pressurizing piston block 25 to slide up and down reciprocally in the pressurizing piston groove 212. When the pressurizing piston block 25 moves downward, the pressure in the receiving cavity 111 can be increased, so that the fiber liquid flows downward through the spinning holes 421 of the spinneret 42, thereby forming fiber filaments. When the pressurizing piston block 25 moves upward, the pressure in the receiving cavity 111 decreases, and the gas enters the receiving cavity 111 through the filtering mechanism 30 and the air inlet pipe 16. At this time, since the pressure in the receiving cavity 111 decreases, the fiber liquid pauses or slows down the downward extrusion and outflow. At this time, the cooling mechanism 50 can better cool and shape the fiber filaments through the spinneret 41. When the pressurizing piston block 25 moves downward again, through pressurization and cooling, the fiber liquid continues to flow downward to form fiber filaments. By opening the plugging cap 15 and using the introduction pipe 14 to introduce the fiber liquid, the addition of the fiber liquid can be conveniently carried out. Reinstalling the plugging cap 15 for sealing can prevent the fiber liquid from leaking in subsequent operations and keep the internal environment of the equipment

[0054] clean and stable. The start of the pressurizing motor 22 causes the rotation of the reciprocating lead screw 24, and the movement of the pressurizing piston block 25 realizes the internal

[0055] pressure regulation. The pressure is intermittently generated in the receiving cavity 111 to provide power for the spinning of the fiber liquid. The spinning holes 421 on the spinneret 42 ensure the uniform ejection of the fiber liquid, forming continuous fiber filaments. The function of the cooling mechanism 50 is to quickly cool the ejected fiber filaments to achieve an immediate shaping effect. The cooling process helps to improve the strength and durability of the fiber filaments, while reducing thermal stress and shrinkage, and improving the overall processing quality.

[0056] When the pressurizing piston block 25 moves upward, the gas enters the filter cavity 321 through the filter pipe 35, then enters the intake pipe 16 through the filter screen 34 and the filter core 33, and then enters the receiving cavity 111 from the intake pipe 16, so as to realize the filtration and introduction of the gas, improve the purity of the gas, and prevent dust from entering the receiving cavity 111. The one-way valve 161 can prevent the gas from flowing in the direction of the filter cavity 321 when the pressurizing piston block 25 moves downward, improve the reliability of the device. When the pressurizing rotating shaft 23 rotates, it can drive the driving gear 231 to rotate. The driving gear 231 can drive the passive gear 214 meshing with it to rotate. The passive gear 214 can drive the linkage rotating shaft 215 to rotate around the axis of the passive rotating shaft 213. The linkage rotating shaft 215 can drive the linkage swing rod 216 to swing. The linkage swing rod 216 can drive the linkage telescopic rod 217 to reciprocate. The linkage telescopic rod 217 can drive the cleaning plate 218 to reciprocate, so as to realize the cleaning of the filter screen 34, avoid the blockage of the filter screen 34 affecting the gas flow effect. The one-way valve 161 can prevent the gas from flowing back to the filter cavity 321 when the pressurizing piston block 25 moves downward, so as to ensure the correct gas flow direction. By driving the movement of the gear 231, the passive gear 214, the linkage rotating shaft 215 and the linkage swing rod 216 through the rotation of the pressurizing rotating shaft 23, the linkage telescopic rod 217 and the cleaning plate 218 can reciprocate, so as to realize the automatic cleaning of the filter screen 34, avoid the blockage problem caused by the accumulation of dust on the filter screen 34, keep the filter screen 34 unobstructed, and improve the gas flow effect.

[0057] The cooling gas generated by the cooling air pump 52 can enter the annular cooling groove 415 through the cooling connecting pipe 53 and the cooling groove 417. Part of the cooling gas in the annular cooling groove 415 can flow directly downward through the cooling vertical hole 416, and the other part of the gas will enter the several connecting annular grooves 423 and the connecting circular grooves 424 through the cooling extension grooves 425. The cooling gas in the connecting annular grooves 423 and the connecting circular grooves 424 can flow out obliquely downward through the cooling inclined holes 422. The cooling gas flowing out obliquely downward can better act on the fiber filaments, so that the fiber filaments can be better cooled and shaped. The ejected fiber filaments will be inclined in a direction away from the central axis of the spinneret 42 due to the obliquely blown cooling gas. The inclination of the fiber filaments can make the cooling gas flowing downward through the cooling vertical holes 416 further cool the fiber filaments, thereby improving the cooling effect of the fiber filaments. The cooling air pump 52 generates cooling gas, which enters the annular cooling groove 415 through the cooling connecting pipe 53 and the cooling groove 417, so that part of the gas flows directly downward through the cooling vertical hole 416, and the other part of the gas flows out obliquely downward through the cooling inclined hole 422. The cooling gas flowing out obliquely downward can make the fiber filaments cool and shape while tilting away from the central axis of the spinneret 42. The gas flowing directly downward can take away the heat of the inclined fiber filaments, so that the fiber filaments are evenly cooled, which helps to maintain consistent physical properties and quality of the fiber filaments during the shaping process. The cooling gas flowing out of the cooling inclined hole 422 performs preliminary cooling and shaping on the fiber filaments, and the cooling gas flowing out of the cooling vertical hole 416 further cools and shapes the fiber filaments, more effectively reducing the temperature of the fiber filaments and increasing the cooling rate, thereby better fixing the shape and properties of the fiber filaments.

[0058] In another embodiment, the operator can toggle the toggle arc rod 62 so that the toggle arc rod 62 slides in the toggle arc groove 418, the toggle arc rod 62 can drive the adjusting ring block 61 to rotate, the adjusting ring block 61 can drive a plurality of first shielding arc blocks 63 to rotate, and when the first shielding arc block 63 rotates, the top of the corresponding spinneret hole 421 can be exposed through the first notch 631 and the second notch 632, the adjusting ring block 61 can drive the passive ring block 71 to rotate through the two connecting arc rods 711, the passive ring block 71 can drive a plurality of second shielding arc blocks 72 to rotate, and when the second shielding arc block 72 rotates

[0059] The bottom of the corresponding cooling inclined hole 422 and the spinneret hole 421 can be exposed through the third notch 721 and the fourth notch 722, and the spinneret hole 421 can be sprayed.

[0060] After the top and bottom of the filament hole 421 are exposed, the fiber liquid can smoothly pass through the opened corresponding spinneret hole 421 to form fiber filaments. The number of spinnerets is increased by opening the spinneret hole 421, and the corresponding cooling inclined hole 422 is opened to assist in the cooling and shaping of the fiber filaments. By adjusting the toggle arc rod 62, the rotation of the adjusting ring block 61 is controlled, thereby driving the rotation of the first shielding arc block 63, so that the top of the spinneret hole 421 can be exposed. The adjusting ring block 61 also drives the rotation of the passive ring block 71 by connecting the arc rod 711, thereby further adjusting the position of the second shielding arc block 72, and controlling the opening and closing state of the bottom of the corresponding spinneret hole 421 and the cooling inclined hole 422. By opening more spinneret holes 421, the number of fiber liquid sprayed can be increased, thereby improving production efficiency. By controlling the opening and closing of the cooling inclined hole 422, the cooling and shaping of the fiber filaments can be effectively assisted, ensuring that the fiber filaments maintain a stable cooling effect during the process of increasing the number of forming, and comprehensively adjusting the fiber liquid spraying and cooling.

[0061] When the number of opened spinneret holes 421 increases, the single moving distance of the pressurizing piston block 25 from the top to the bottom remains unchanged, and the length of the fiber filament formed by the spinneret holes 421 at a time becomes shorter. Moreover, since the number of opened cooling inclined holes 422 increases, more gas can enter the several connecting annular grooves 423 and the connecting circular grooves 424 through the cooling extension grooves 425, and the gas flowing out of the corresponding cooling vertical holes 416 decreases, and the position of the fiber filament involved by the flowing cooling gas becomes closer, which is just suitable for the change in the length of the fiber filament, so that more cooling gas can be cooled through the cooling inclined holes 422. Adjusting the number of opened spinneret holes 421 can make the cooling gas adaptively adjusted, thereby improving the cooling efficiency. The utilization efficiency of cooling gas is improved, that is, when a smaller number of spinneret holes 421 are opened, the length of fiber filaments formed at a single time is longer, and a smaller number of cooling inclined holes 422 are opened, and the cooling gas flowing out of the cooling vertical holes 416 can cover a longer distance; when a larger number of spinneret holes 421 are opened, the length of fiber filaments formed at a single time is shorter, and a larger number of cooling inclined holes 422 are opened, and the cooling gas flowing out of the cooling vertical holes 416 can cover a longer distance, both of which can better adapt to the length of fiber filaments formed at a single time. As the number of spinneret holes 421 increases or decreases, the cooling gas can be better utilized, and the flow and distribution of the cooling gas can be adjusted to adapt to new production conditions, thereby improving the utilization efficiency of the cooling gas and reducing energy waste.

[0062] This case can achieve the following: 1. By opening the plugging cap 15 and using the introduction pipeline 14 to introduce the fiber liquid, the addition of the fiber liquid can be conveniently carried out. After reinstalling the plugging cap 15 for sealing, it can prevent the leakage of the fiber liquid during subsequent operations, maintain the cleanliness and stability of the internal environment of the equipment. The start of the pressurizing motor 22 causes the rotation of the reciprocating lead screw 24, and the internal pressure is adjusted through the movement of the pressurizing piston block 25. Pressure is intermittently generated in the receiving cavity 111, providing power for the spinning of the fiber liquid. The spinning holes 421 on the spinneret 42 ensure the uniform ejection of the fiber liquid, forming continuous fiber filaments. The function of the cooling mechanism 50 is to quickly cool the ejected fiber filaments to achieve an immediate shaping effect. The cooling process helps to improve the strength and durability of the fiber filaments, while reducing thermal stress and shrinkage, and improving the overall processing quality.

[0063] 2. The one-way valve 161 can prevent the gas from flowing back into the filtering cavity 321 when the pressurizing piston block 25 moves downward, thus ensuring the correct direction of gas flow. The rotation of the pressurizing rotating shaft 23 drives the movement of the gear 231, the passive gear 214, the linkage rotating shaft 215 and the linkage swing rod 216, enabling the linkage telescopic rod 217 and the cleaning plate 218 to reciprocate, thereby realizing the automatic cleaning of the filter net 34, avoiding the blockage problem of the filter net 34 caused by dust accumulation, keeping the filter net 34 unobstructed, and improving the gas flow effect.

[0064] 3. Cooling gas is generated by the cooling air pump 52. The cooling gas enters the annular cooling groove 415 through the cooling connection pipe 53 and the cooling through groove 417, enabling a part of the gas to flow directly downward through the cooling vertical holes 416, and another part of the gas to flow obliquely downward through the cooling inclined holes 422. The cooling gas flowing obliquely downward can cool and shape the fiber filaments while tilting them away from the central axis of the spinneret 42. The gas flowing directly downward can take away the heat of the tilted fiber filaments,

[0065] making the fiber filaments be evenly cooled, which helps the fiber filaments to maintain consistent physical properties and quality during the shaping process.

[0066] The cooling gas flowing out of the cooling inclined holes 422 initially cools and shapes the fiber filaments, and the cooling gas flowing out of the cooling vertical holes 416 further cools and forms the fiber filaments, more effectively reducing the temperature of the fiber filaments, increasing the cooling rate, and thus better fixing the shape and performance of the fiber filaments.

[0067] 4. By adjusting the toggle arc rod 62, the rotation of the adjusting ring block 61 is controlled, and then the rotation of the first shielding arc block 63 is driven, so that the top of the spinneret hole 421 can be exposed. The adjusting ring block 61 also drives the rotation of the passive ring block 71 by connecting the arc rod 711, so as to further adjust the position of the second shielding arc block 72, and control the opening and closing state of the bottom of the corresponding spinneret hole 421 and the cooling inclined hole 422. By opening more spinneret holes 421, the number of fiber liquid sprayed can be increased, thereby improving production efficiency. By controlling the opening and closing of the cooling inclined hole 422, the cooling and shaping of the fiber filaments can be effectively assisted, ensuring that the fiber filaments maintain a stable cooling effect during the process of increasing the number of moldings, and comprehensively adjusting the fiber liquid spraying and cooling.

[0068] 5. When a small number of spinneret holes 421 are opened, the length of the fiber filament formed at a single time is longer, and a small number of cooling inclined holes 422 are opened, and the cooling gas flowing out of the cooling vertical hole 416 can cover a longer distance. When a large number of spinneret holes 421 are opened, the length of the fiber filament formed at a single time is shorter, and a large number of cooling inclined holes 422 are opened, and the cooling gas flowing out of the cooling vertical hole 416 can cover a longer distance. Both can better adapt to the length of the fiber filament formed at a single time. As the number of spinneret holes 421 increases or decreases, the cooling gas can be better utilized, and the flow rate and distribution of the cooling gas can be adjusted to adapt to new production conditions, thereby improving the utilization efficiency of the cooling gas and reducing energy waste.

[0069] All possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The above-described embodiments only express several embodiments of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention.

Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
