Description

Technical Field

[0001] This application relates to the field of melt spinning technology, and in particular to a melt injection device that allows for switching between multiple main materials and masterbatches. Background Technology

[0002] Traditional melt injection equipment is designed primarily based on a single-raw-material production model. The screw system, feeding method, metering machine, and other components of the equipment are customized specifically for processing a single type of raw material. While these equipment configurations can efficiently complete the proportioning of a single main material and masterbatch, they are not adaptable when faced with combinations of multiple main materials and masterbatches. They cannot flexibly adjust the proportion of raw materials and the processing speed, resulting in low efficiency when switching raw materials.

[0003] With the increasing demand for differentiated fiber products, the industry is increasingly demanding the ability to produce multiple raw materials and switch quickly. How to achieve rapid switching between this single main material and masterbatch production mode and the combination of multiple main materials and masterbatches has become a challenge for the technological development of the chemical fiber industry.

[0004] Therefore, we need a melt injection device that allows for switching between multiple main ingredients and masterbatches, which can solve the problem of how to quickly switch between two combinations of single main ingredients and masterbatches or multiple main ingredients and masterbatches. Utility Model Content

[0005] The purpose of this application is to provide a melt injection device that allows for switching between multiple main materials and masterbatches, which can solve the problem of how to quickly switch between two combination modes: a single main material and masterbatch or multiple main materials and masterbatches.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solution: a melt injection device with switchable main raw materials and masterbatch for multiple varieties, comprising: a main raw material metering device and a masterbatch metering device; inlets at both ends of a mixing silo, which are respectively connected to the discharge pipes of the main raw material metering device and the masterbatch metering device; an outlet at the bottom of the mixing silo connected to a small screw; and an opening at the front end of the mixing silo; a first door-changing structure, which is located on the opening of the mixing silo and has multiple connection holes; an integrated sealing gasket layer inside the first door-changing structure; and a handle on the outside of the first door-changing structure; and a second door-changing structure, which has an interface that is inclined and has a flexible hose, with a buckle on the outside of the hose that engages with the interface; one end of the hose that engages with the interface and the other end of the hose that engages with the drying tower; the second door-changing structure is a replacement for the first door-changing structure, and only one of the two door-changing structures is installed at a time.

[0007] In the above technical solution, this application embodiment switches between different processing modes by replacing door structure one and door structure two. In mode one, different masterbatches are added to the drying tower for dehydration. After removing the moisture from the masterbatches, they are sent to a constant temperature and humidity storage tank through hose three. The masterbatches are metered by a masterbatch metering machine and accurately metered according to the required ratio before entering the mixing silo. At the same time, the main material is transported to the main material metering machine through branch pipelines and storage silos. After being metered by the main material metering machine, it enters the mixing silo. The mixing silo then mixes the main material and masterbatch. The process involves mixing multiple main raw materials and masterbatches, melting them using a small screw, and injecting the mixture into designated spindle positions. The resulting yarn is then spun into colored yarn through a spinning box. Alternatively, multiple main raw materials can be pre-mixed manually in the required proportions using a mixing machine. After mixing, depending on the production batch size, the mixture is fed manually or via vacuum suction and then added to a drying tower for dehydration. Alternatively, a single main raw material can be directly added to the drying tower for dehydration, then transported directly to the mixing silo via a hose, and then melted and injected into designated spindle positions via a small screw. This allows for the simultaneous spinning of both colored and white yarns on a single screw spinning position. This method solves the problem of quickly switching between two combination modes: single main raw material and masterbatch, or multiple main raw materials and masterbatch.

[0008] Furthermore, according to an embodiment of this application, a storage silo is also provided above the main material metering device, the storage silo is connected to the main material tank, and the main material tank is provided with a main pipeline and branch pipelines.

[0009] Furthermore, according to an embodiment of this application, the branch pipeline connects the storage silo and the main material metering device, and the storage silo is provided with a second flexible hose, which connects the discharge pipeline of the storage silo and the main material metering device.

[0010] Furthermore, according to an embodiment of this application, the main pipeline connects the main screw and the spinning box, and multiple distribution pipelines are provided between the main screw and the spinning box, the distribution pipelines injecting the molten main material from the main screw into different spindle positions.

[0011] Furthermore, according to an embodiment of this application, a valve is provided on the spindle position, and one side of the spindle position is connected to a small screw.

[0012] Furthermore, according to an embodiment of this application, a storage tank is also provided above the masterbatch metering device, and a flexible hose is provided above the storage tank, with the other end of the flexible hose connected to the drying tower.

[0013] Furthermore, according to the embodiments of this application, the drying tower is used for dehydrating masterbatch, the internal environment of the storage tank is set to constant temperature and humidity, and the storage tank is used to store the dehydrating masterbatch.

[0014] Furthermore, according to an embodiment of this application, the mixing hopper and the door changing structure are connected by a knob, and there are multiple knobs, which are disposed in the connection hole.

[0015] Furthermore, according to an embodiment of this application, the door structure is internally provided with an integrated sealing gasket layer, which is used to prevent material leakage.

[0016] Furthermore, according to the embodiments of this application, the second door replacement structure is internally fitted with a high-temperature resistant sealing gasket layer, and the second door replacement structure is used to replace the first door replacement structure to switch the melt injection mode.

[0017] Compared with the prior art, this application has the following advantages: This application adopts a melt injection device with switchable main raw materials and masterbatch. By replacing the first and second switching gate structures, different processing modes can be switched. In mode one, different masterbatches are added to the drying tower for dehydration treatment. After removing the moisture from the masterbatches, they are sent to the constant temperature and humidity storage tank through the third hose. The masterbatches are metered by the masterbatch metering machine and accurately metered according to the required ratio before entering the mixing silo. At the same time, the main raw materials are transported to the main raw material metering machine through the branch pipeline and the storage silo. After being metered by the main raw material metering machine, they enter the mixing silo. Inside the silo, the main raw materials and masterbatch are mixed in a mixing silo, then melted by a small screw and injected into designated spindle positions. The resulting yarn is then spun into colored yarn through the spinning box. In mode two, multiple main raw materials and masterbatches are pre-mixed manually in the required proportions using a mixing machine. After mixing, depending on the production batch, the mixture is fed manually or via vacuum suction and added to a drying tower for dehydration. Alternatively, a single multi-variety main raw material can be directly added to the drying tower for dehydration, then transported directly to the mixing silo via a hose, and then melted and injected into designated spindle positions by a small screw. This allows a single screw spinning position to simultaneously spin both colored and white yarn. This method solves the problem of quickly switching between two combination modes: single main raw material and masterbatch or multiple main raw materials and masterbatch, achieving the effect of rapid switching between these two combination modes.

Furthermore, all embodiments can be used in combination with each other.

[0029] Example 1:

[0030] like Figure 1-4As shown, this application discloses a melt injection device with switchable main raw materials and masterbatch, including: a main raw material metering device 3 and a masterbatch metering device 6; a mixing hopper 7 with inlets at both ends, which are connected to the outlet pipes of the main raw material metering device 3 and the masterbatch metering device 6 respectively; an outlet at the bottom of the mixing hopper 7 connected to a small screw 11; and an opening at the front end of the mixing hopper 7; a door-changing structure 8, which is disposed on the opening of the mixing hopper 7, has multiple connection holes, and an integrated sealing gasket layer inside the door-changing structure 8. The first door structure 8 has a handle 801 on its outer side; the second door structure 9 has an interface 903 on its outer side. The interface 903 is inclined and has a flexible hose 901 on its outer side. The flexible hose 901 has a buckle 902 on its outer side. The buckle 902 is locked to the outer side of the flexible hose 901 and the interface 903. One end of the flexible hose 901 is connected to the interface 903 and the other end of the flexible hose 901 is connected to the drying tower 4. The second door structure 9 is a replacement for the first door structure 8. Only one of the first door structure 8 and the second door structure 9 can be installed at a time.

[0031] Above the main material metering device 3, a storage silo 2 is also provided, which is connected to the main material tank 1. The main material tank 1 is equipped with a main pipeline 101 and a branch pipeline 102. The branch pipeline 102 connects the storage silo 2 and the main material metering device 3. A second hose 201 is provided on the storage silo 2, which connects the storage silo 2 and the discharge pipeline of the main material metering device 3. The second hose 201 is used for venting, thereby balancing the pressure inside the storage silo 2. The main pipeline 101 connects the main screw 13 and the spinning box 14. Multiple distribution pipelines are provided between the main screw 13 and the spinning box 14, which inject the molten main material from the main screw 13 into different spindle positions. A valve 12 is provided on each spindle position, and one side of the spindle position is connected to a small screw 11.

[0032] Above the masterbatch metering device 6, there is a storage tank 5. Above the storage tank 5, there is a flexible hose 401, the other end of which is connected to the drying tower 4. The drying tower 4 is used to dehydrate the masterbatch. The internal environment of the storage tank 5 is set to constant temperature and humidity, and the storage tank 5 is used to store the dehydrated masterbatch.

[0033] The mixing chamber 7 and the door changing structure 8 are connected by a knob 10. There are multiple knobs 10, and the knobs 10 are set in the connection hole.

[0034] The internal structure of the door replacement structure 8 features an integrated sealing gasket to prevent material leakage. The door replacement structure 8 uses a plastic hopper cover to form a detachable structure with the mixing hopper 7. Six evenly distributed knobs 10 form a quick-locking mechanism for rapid assembly and disassembly. The double symmetrical handles 801 on the outside of the door replacement structure 8 enable convenient one-handed operation for assembly and disassembly, achieving lightweight and corrosion resistance while ensuring structural strength.

[0035] The second door structure 9 is internally fitted with a high-temperature resistant sealing gasket. It replaces the first door structure 8 to switch the melt injection mode. The second door structure 9 is an integrated welded structure of an iron cover and pipe. Six circumferentially distributed knobs 10 enable quick and tight sealing between the second door structure 9 and the mixing chamber 7. The iron cover has a built-in interface 903, allowing for plug-and-play switching of different hose specifications via quick-release clips 902, enabling pipe adaptation without additional tools. Compared to the detachable plastic structure of the first mode, this door structure, through a customized metal welding process module, significantly improves the overall structural strength and pressure resistance. The improved welded frame retains the quick-locking advantage of the knobs 10 in the first mode while eliminating the risk of seal failure due to the aging and deformation of plastic materials. Furthermore, its high-temperature resistant sealing gasket can block the heat emitted by the freshly dried material.

[0036] Example 2:

[0037] In Mode 1, a door-changing structure 8 is installed on the mixing silo 7. Different masterbatches are added to the drying tower 4 for dehydration. After the moisture is removed from the masterbatches, they are sent to the constant temperature and humidity storage tank 5 through hose 3 401 for storage. While the masterbatch metering machine retrieves production materials from the storage tank 5, the drying tower 4 continues to feed and dry the masterbatches. The masterbatches are metered by the masterbatch metering machine and accurately measured according to the required ratio before entering the mixing silo 7. At the same time, the main material does not need to be dehydrated and is directly taken from the dried material tank 1. The main material and masterbatch are processed separately. The main material is processed through the branch pipe. The material is conveyed from pipe 102 and storage silo 2 to the main material metering machine. After being metered by the main material metering machine, it enters the mixing silo 7. The mixing silo 7 mixes the main material and masterbatch, then melts it through the small screw 11 and injects it into the designated spindle position. The spindle position is equipped with a valve 12 to isolate the main material from the main screw 13. Then, the colored yarn is spun through the spinning box 14. On the main pipeline 101, the main material is melted by the main screw 13 and injected into other spindle positions. Then, the white yarn is spun through the spinning box 14. Thus, it is possible to spin colored yarn and white yarn simultaneously on a single screw spinning position.

[0038] Mode 1, with its precise proportioning of a single main ingredient and a masterbatch mill, is suitable for small-batch filament production. The main ingredient does not require dehydration; pre-dried material from main ingredient tank 1 is used directly, saving energy. Furthermore, the precise proportions from the masterbatch mill into mixing bin 7 ensure mixing accuracy. Finally, melt injection makes it suitable for products with high strength requirements. However, Mode 1 uses a single main ingredient, making it unsuitable for diverse raw material needs. The masterbatch addition ratio is limited by the metering machine's range, resulting in poor adjustment flexibility, typically within 5%. Additionally, the system requires continuous operation of the masterbatch metering device, leading to high energy consumption.

[0039] Example 3:

[0040] In Mode 2, a door-changing structure 9 is installed on the mixing silo 7. Multiple main materials and masterbatches are pre-mixed manually in the required proportions according to production specifications. After mixing, manual feeding or vacuum feeding is selected based on the production batch size. The mixed material is then added to the drying tower 4 for dehydration. Alternatively, a single multi-variety main material can be directly added to the drying tower 4 for dehydration. The mixing silo 7 is connected to the lower end of the drying tower 4 via a hose 901 on the door-changing structure 9. The dehydrated material is directly conveyed to the mixing silo 7 via hose 901, then melted and injected into a designated spindle position via a small screw 11. A valve 12 at this spindle position isolates the main material from the main screw 13. The material is then spun into colored yarn via the spinning box 14. On the main pipeline 101, the main material is melted by the main screw 13 and injected into other spindle positions, where it is then spun into white yarn via the spinning box 14. This allows for the simultaneous spinning of colored and white yarn on a single screw spinning position.

[0041] Mode 2 achieves rapid material channel changes by switching the gate structure 29 and connecting hose 901 to drying tower 4. It allows for the manual mixing of multiple main ingredients and masterbatches, or the direct addition of a single multi-ingredient main ingredient, making it suitable for large-scale standardized production. Mode 2 offers high flexibility, supporting free combinations of multiple main ingredients and masterbatches, or a single multi-ingredient main ingredient. The mixing ratio is not limited by equipment and does not require starting the masterbatch machine, thus reducing power consumption. It also allows for quick switching of the gate mechanism, with convenient and effective installation and disassembly, restoring the state of Mode 1. This allows for quick switching between the two modes to find a more suitable method according to customer needs. It solves the problem of how to quickly switch between two combination modes: single main ingredient and masterbatch, or multiple main ingredients and masterbatch, achieving the effect of rapid switching between these two combination modes.

[0042] Although the illustrative specific embodiments of this application have been described above to enable those skilled in the art to understand this application, this application is not limited to the scope of the specific embodiments. For those skilled in the art, all applications utilizing the concept of this application are protected as long as various variations are within the spirit and scope of this application as defined and determined by the appended claims.
