[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figures 1-6 As shown, a spinneret device with multiple spinnerets includes:

[0028] The main unit base 1 has a bracket 2 installed on one side of its upper end. A bracket 3 is installed on the upper end of the bracket 2. A distribution block body 4 is set on one side of the bracket 3. An extruder system is connected to one side of the distribution block body 4. The extruder system includes an extruder and a plate screen changer 14, both of which are existing technologies and will not be described in detail here. A reducer 8 is installed on the upper end of the bracket 3. A drive shaft 7 is connected to the output end of the reducer 8. A melt pump 6 is installed on the lower end of the drive shaft 7. The melt pump 6 is connected to the distribution block body 4 through a transition block 5. An installation groove that mates with the transition block 5 is opened on the upper end of the distribution block body 4 for installing the transition block 5. A spinneret 12 is set on the lower end of the distribution block body 4 for spinning. A spinneret filter screen is also set between the lower end of the distribution block body 4 and the spinneret 12.

[0029] The main body of the distribution block 4 has a flow channel 41 on one side and two sets of vertical channels 42 on the inside. The two sets of vertical channels 42 are connected to the flow channel 41. The main body of the distribution block 4 has a vertical channel 44 on the other side and a flow channel 43 on the inside. The flow channel 43 is connected to the vertical channel 44. Both the vertical channel 42 and the flow channel 43 are connected to the melt pump 6.

[0030] It should be noted that melt pumps are mainly used for conveying, pressurizing, and metering high-temperature, high-viscosity polymer melts. A melt pump is a positive displacement conveying device; the flow rate is strictly proportional to the pump's rotational speed. It mainly consists of a pump casing, driving gear, driven gear, sliding bearings, front and rear end plates, and packing seals. The feed zone, conveying zone, and discharge zone are formed by the tooth profiles of the two gears, the pump body, and the side cover plates. During operation, the melt is conveyed by the change in working volume caused by the meshing of the driving and driven gears. The working volume is formed by the pump body, the gear tooth grooves, and the bearings (which function as side plates) (i.e., the feed zone). When the gears rotate in the specified direction, the melt enters the tooth grooves of the two gears in the feed zone. As the gears rotate, the melt is carried from both sides into the conveying zone. The re-meshing of the gears forces the melt in the tooth grooves out of the discharge zone and pressurized into the outlet pipe. As long as the pump shaft rotates, the gears will press the melt towards the outlet side, so the pump outlet can reach a very high pressure, while there are no high requirements for the inlet flow rate and pressure, and it can even achieve inlet vacuum suction.

[0031] refer to Figures 1-6 As shown, the flow channel 41 is set in a V shape, so that the material of the twin screw extruder is diverted through the flow channel 41 and flows to two sets of vertical channels 42 respectively. Then it is sucked into the inlet of the melt pump 6, and after being pressurized, it enters the flow channel 43 from the outlet of the melt pump 6, and then flows into the vertical channel 44 and is spun from the spinneret 12 at the lower end.

[0032] The flow channel design enables the material extruded from the co-rotating parallel twin-screw compounding extruder to be divided into two parts, which enter the melt pump and then the flow channel connected to the spinneret.

[0033] refer to Figures 1-6 As shown, the outer side of the main body 4 of the distribution block is provided with a waist-shaped hole 49 for connecting with the plate screen changer of the twin-screw extruder to realize feeding. The waist-shaped hole 49 is connected to the flow channel 41.

[0034] refer to Figures 1-6 As shown, the lower end of the main body 4 of the distribution block is provided with a channel outlet 45 for material discharge, which works with the spinneret 12 to achieve spinnereting. The channel outlet 45 is connected to the vertical channel 44.

[0035] refer to Figures 1-6 As shown, the upper end of the distribution block body 4 is provided with a feed inlet 46 and a discharge outlet 47. The lower end of the feed inlet 46 is connected to the vertical channel 42, and the upper end of the feed inlet 46 is connected to the inlet of the melt pump 6, so that the material enters the melt pump 6 for pressurization. The lower end of the discharge outlet 47 is connected to the flow channel 43, and the upper end of the discharge outlet 47 is connected to the outlet of the melt pump 6, so that the pressurized material enters the flow channel 43 from the discharge outlet 47, then enters the vertical channel 44 and is ejected through the spinneret 12 to achieve spinnereting.

[0036] refer to Figures 1-6 As shown, a heater 9 is provided on the outside of the main body 4 of the distribution block, which serves as a heating element.

[0037] refer to Figures 1-6 As shown, a fixing hole 48 is also provided at the upper end of the main body 4 of the distribution block, and a pressure sensor 10 is installed inside the fixing hole 48.

[0038] refer to Figures 1-6 As shown, a thermocouple 13 is also installed on the outside of the main body 4 of the distribution block.

[0039] refer to Figures 1-6 As shown, a sealing gasket is provided at the upper end of the mounting plate 30, which is beneficial for achieving a seal.

[0040] This utility model, through the multi-channel design of the distribution block body 4, allows the twin-screw extruder to send the produced material through the first channel and the first vertical channel 42 of the distribution block body 4 into the melt pump 6. After being pressurized, the material enters the second channel 43 and the second vertical channel 44 from the outlet of the melt pump 6, and is finally spun from the spinneret 12. This design can meet actual production needs and save production costs.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
