Description

Technical Field

[0001] This utility model relates to the field of spinning machine equipment technology, and in particular to a three-box composite spinning machine. Background Technology

[0002] With the widespread use of new composite fiber materials, composite spinning boxes need to be able to adapt to the composite molding of materials with different thermal degradation properties, such as PE / PA66, high and low viscosity PLA composites, etc. The differences in the characteristics of the two components are becoming increasingly large, so composite spinning boxes need to meet the requirements of multi-temperature process adjustment.

[0003] Currently, the composite spinning box is an important component in the spinning machine. It plays a role in containing and distributing the spinning melt. Two polymer melts with different properties are delivered to the appropriate part of the same component by two separate metering pumps and then extruded in the same spinning hole to form composite fibers with different structures, such as core-sheath composite fibers and parallel composite fibers. The current composite spinning box structure is a two-box structure. The A component distribution metering box is heated by a biphenyl-diphenyl ether system, and the B component distribution metering box is located in the same main box where the composite component spinning is heated by another biphenyl-diphenyl ether system.

[0004] The existing technical solutions have the following drawbacks: The existing composite spinning box structure consists of two boxes. The A component area is heated by a biphenyl-diphenyl ether system, while the B component area and the composite component area are heated by a biphenyl-diphenyl ether system. If the B component uses a higher spinning temperature, it will degrade prematurely in the metering section, affecting the fiber quality. If the B component uses a lower spinning temperature, the melt viscosity will be too high, affecting the spinnability of the fiber. Utility Model Content

[0005] The purpose of this invention is to provide a three-box composite spinning machine to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

The first and second auxiliary boxes are symmetrically arranged on the top sides of the main box. The main box has a hollow interior and contains a mixing box. The mixing box contains six spinning positions, each of which is connected to a first metering pump assembly and a second metering pump assembly via a pipeline device. The first and second metering pump assemblies are symmetrically arranged on the top sides of the main box. The first metering pump assembly, the second metering pump assembly, and the mixing box are detachably fitted with a jacket, and a heating system is installed inside the jacket.

[0008] By adopting the above technical solution, the first metering pump assembly, the second metering pump assembly, and the mixing box are set independently, ensuring that each of the first metering pump assembly, the second metering pump assembly, and the mixing box has its own independent heating system. This allows the spinning machine to adapt to the composite molding of spinning melts with different thermal degradation properties, meet different process temperature settings, avoid thermal degradation of different spinning melts in the first metering pump assembly and the second metering pump assembly, and ultimately improve the spinning quality.

[0013] In a further embodiment, the first liquid inlet is connected to one end of a first pipe, the other end of the first pipe is connected to a first auxiliary housing, the second liquid inlet is connected to one end of a second pipe, and the other end of the second pipe is connected to a second auxiliary housing.

[0014] In a further embodiment, the heating medium is biphenyl-biphenyl ether.

[0023] Example 1:

[0024] like Figures 1-3 As shown, a three-box composite spinning machine 1 includes a main box 2, a first auxiliary box 11, and a second auxiliary box 12. The first auxiliary box 11 and the second auxiliary box 12 are symmetrically arranged on the top sides of the main box 2. The interior of the main box 2 is hollow, and a mixing box 3 is arranged inside the main box 2. The mixing box 3 contains six spinning positions arranged from front to back. Each spinning position is connected to a first metering pump assembly 4 and a second metering pump assembly 5 through a pipeline device 10. The first metering pump assembly 4 and the second metering pump assembly 5 are symmetrically arranged on the top sides of the main box 2. The first metering pump assembly 4, the second metering pump assembly 5, and the mixing box 3 are detachably fitted with a jacket. The inside of the jacket can be circulated with biphenyl-diphenyl ether.

[0025] The first metering pump assembly 4 is provided with a first liquid outlet, a second liquid outlet, a third liquid outlet, a fourth liquid outlet, and a first liquid inlet; the second metering pump assembly 5 is provided with a fifth liquid outlet, a sixth liquid outlet, a seventh liquid outlet, an eighth liquid outlet, and a second liquid inlet; the top of the spinning position is provided with a first connecting cover 6, a second connecting cover 7, a third connecting cover 8, and a fourth connecting cover 9, the top of each of the first connecting cover 6, the second connecting cover 7, the third connecting cover 8, and the fourth connecting cover 9 is provided with a first connecting port and a second connecting port that are vertically connected, the first connecting port being located to the left of the second connecting port; the tube The pipeline device 10 includes a first pipeline system 101 and a second pipeline system 102, which are mirror images of each other. The first pipeline system 101 includes a first distribution pipe, a second distribution pipe, a third distribution pipe, and a fourth distribution pipe. The second pipeline system 102 includes a fifth distribution pipe, a sixth distribution pipe, a seventh distribution pipe, and an eighth distribution pipe. A first inlet is connected to one end of a first pipe, and the other end of the first pipe is connected to a first auxiliary housing 11. A second inlet is connected to one end of a second pipe, and the other end of the second pipe is connected to a second auxiliary housing 12.

[0026] Specific implementation process: The first sub-box 11 contains a first type of spinning melt, and the second sub-box 12 contains a second type of spinning melt. The first type of spinning melt enters the first metering pump assembly 4 through a first pipe connected to the first inlet of the first metering pump assembly 4. The second type of spinning melt flows into the second metering pump assembly 5 through a second pipe connected to the second inlet of the second metering pump assembly 5. Inside the first metering pump assembly 4, the first metering pump assembly 4 maintains a first temperature through an independent jacket containing biphenyl-diphenyl ether. The first type of spinning melt flows into the mixing tank 3 through different outlets in coordination with the first piping system. Similarly, the second metering pump assembly 5 maintains a second temperature through an independent jacket containing biphenyl-diphenyl ether. Temperature: The second type of spinning melt flows into the mixing tank 3 through different outlets in conjunction with the second pipeline system. The mixing tank 3 maintains a third temperature through an independent jacket containing biphenyl-diphenyl ether. Then, the biphenyl-diphenyl ether in the jacket outside the mixing tank 3 can heat and keep the first and second types of spinning melts in the mixing tank 3 at the same temperature, ensuring that the first metering pump assembly 4 and the second metering pump assembly 5 are strictly temperature isolated from the mixing tank 3. This satisfies the composite molding of spinning melts with different thermal degradation properties, allowing the mixing tank 3 to freely set the spinning temperature without considering the thermal degradation risk of the first type of spinning melt in the first metering pump assembly 4 and the second type of spinning melt in the second metering pump assembly 5, thereby improving the spinning quality.
