Description

Technical Field

[0001] This utility model relates to the field of spinning production technology, and more specifically to an energy-saving electric spindle tank structure. Background Technology

[0002] In the field of yarn twisting in the textile machinery industry, the straight twisting machine is a key piece of equipment for achieving direct twisting or doubling of yarn. The performance of its core component, the electro-spindle assembly, directly affects energy consumption, yarn quality, and production efficiency. During operation, the electro-spindle is driven by a motor to rotate the yarn storage disc and twisting disc at high speed. As the yarn is guided from the twisting disc to the yarn guide above the fixed spindle can, it forms a rotating air ring around the spindle can. The energy consumed by this air ring to overcome air resistance, along with the energy required to drive the spindle itself to rotate, constitutes the main part of the straight twisting machine's energy consumption.

[0003] In recent years, in response to industry demands for energy conservation and emission reduction, energy-saving design of electrostatic precipitator components has become a key research and development focus. Existing energy-saving technologies, such as the energy-saving electrostatic precipitator component proposed in publication number CN104195689A, mainly achieve energy savings by optimizing the diameter ratio between the precipitator and the twisting disc and by setting a tapered reduction section at the bottom of the precipitator to reduce the diameter of the air ring. However, with the continuous development of textile industry technology, new production demands have placed higher challenges on electrostatic precipitator performance, gradually revealing the limitations of existing technologies.

[0004] Existing energy-saving spindle can structures are ill-suited for high-speed, fine-denier industrial yarn production scenarios. To achieve higher production efficiency, modern direct twisting machines are continuously increasing spindle speeds, typically reaching 9000 rpm or even higher. Simultaneously, market demand for lightweight, high-strength industrial yarns (such as those as low as 840 dtex or even finer) is growing. In these high-speed, fine-denier applications, yarn tension is relatively low. The bottom of the existing spindle can, with a diameter of φ220mm to φ225mm, is still too large, resulting in an excessively large air ring diameter. This excessively large air ring not only generates greater air resistance, leading to high energy consumption, but more importantly, it has poor stability, easily vibrating and drifting at high speeds. This increases the risk of friction with the spindle can surface, easily causing yarn fuzzing, pilling, or even breakage, severely impacting product quality and production efficiency.

[0005] Furthermore, the existing yarn guide curved arm structure on top of the spindle can becomes a new energy consumption and quality hazard during high-speed operation. While originally designed to guide the yarn path, this curved arm structure itself disturbs the airflow at extremely high speeds, creating unnecessary air vortices above the spindle can, which consume additional energy. More importantly, the oscillating yarn air ring is highly susceptible to intermittent contact or collision with this curved arm structure. For fine denier industrial yarns with extremely high surface finish requirements, this friction is fatal, directly damaging the yarn and creating defects. Utility Model Content

[0006] To address the technical problems existing in the current electrolytic ingot container, this utility model proposes an energy-saving electrolytic ingot container structure, comprising:

[0007] A yarn storage tray, which is connected to the output shaft of a drive motor and can be driven by the motor to rotate around its axis;

[0008] A twisting disc is connected to the yarn storage disc and rotates coaxially with the yarn storage disc.

[0009] The lower spindle pot is located above the twisting disc and remains fixed in place;

[0010] The upper ingot container is connected to the upper part of the lower ingot container and is fixed relative to the lower ingot container;

[0011] The upper ingot container includes a first height section and a second height section. The first height section of the upper ingot container is constructed with an upwardly tapering diameter, and the top of the upper ingot container is provided with an opening.

[0012] The lower ingot tank includes a third height section and a fourth height section.

[0013] The second height section of the upper ingot tank and the third height section of the lower ingot tank have the same diameter, and the diameter is less than 220mm. The height of the fourth height section is greater than 1 / 2 of the height of the lower ingot tank.

[0014] Preferably, the diameters of the second height section of the upper ingot container and the third height section of the lower ingot container are 205-210 mm.

[0015] Preferably, the first height section of the upper ingot container is constructed as a smooth curved surface with a gradually decreasing diameter, and the lower end of the first height section of the upper ingot container is connected to the upper end of the second height section.

[0020] Preferably, the lower ingot container and the upper ingot container are fixedly connected by a snap-fit ​​structure.

[0021] Compared with the prior art, the advantages of this utility model are:

[0022] By significantly reducing the diameter of the spindle can body to 205-210mm and adopting a composite structure with a streamlined tapered upper section and a long conical lower section, the spindle can work synergistically with the high-speed rotating yarn air ring, making its shape more compact and stable. This not only minimizes the energy consumption of the air ring but also reduces the contact friction between the yarn and various parts of the spindle can, making it particularly suitable for high-quality twisting production of high-speed, fine denier industrial yarn.

[0023] The accompanying drawings are not intended to be drawn to scale. In the drawings, each identical or nearly identical component shown in the various figures may be denoted by the same reference numeral. For clarity, not every component is labeled in each figure. Embodiments of various aspects of the present invention will now be described by way of example and with reference to the accompanying drawings, wherein:

[0024] Figure 1 This is a structural diagram of an electric ingot can in the prior art;

[0025] Figure 2 This is a schematic diagram of the structure of the energy-saving ingot can shown in this utility model. Detailed Implementation

[0026] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0027] like Figure 1 As shown, the current structure of the spindle can is usually cylindrical with a curved arm at the top and a slightly narrower bottom. The diameter is usually greater than 220mm. However, this type of spindle can has the risk of high energy consumption and increased friction between the yarn and the surface of the spindle can, making it difficult to meet the production needs of high-speed, fine denier industrial yarn.

[0028] Combination Figure 2 As shown, this utility model proposes an energy-saving spindle can structure, including a yarn storage tray 1, a twisting tray 2, a lower spindle can 4, and an upper spindle can 5.

[0029] The yarn storage disc 1 is connected to the output shaft of the drive motor and can be driven by the motor to rotate around its axis. The twisting disc 2 is connected to the yarn storage disc 1 and rotates coaxially with the yarn storage disc 1.

[0030] After the yarn is drawn out from the sand storage tray 1, it passes around the edge of the twisting tray 2. The twisting action is applied to the yarn by the rotation of the twisting tray 2 to complete the twisting process. The coaxial connection ensures the directness and efficiency of power transmission and can meet the requirements of high speed operation.

[0031] Furthermore, the lower spindle can 4 is located above the twisting disc 2 and remains fixed, while the upper spindle can 5 is connected above the lower spindle can 4 and is fixed relative to the lower spindle can 4.

[0032] In an optional embodiment, the lower ingot container 4 and the upper ingot container 5 are fixedly connected by a snap-fit ​​structure.

[0033] Combination Figure 2 As shown, the upper ingot tank 5 includes a first height section and a second height section. The first height section of the upper ingot tank 5 is constructed with an upwardly tapering diameter, and the top of the upper ingot tank 5 is provided with an opening 6. The second height section of the upper ingot tank 5 is constructed with a cylindrical structure.

[0034] Preferably, the first height section of the upper ingot container 5 is constructed as a smooth curved surface with a gradually decreasing diameter, and the lower end of the first height section of the upper ingot container 5 is connected to the upper end of the second height section.

[0035] Thus, by setting the first height section as a streamlined, tapering diameter structure, the upward-moving air ring can be smoothly guided, avoiding airflow separation and turbulence caused by right angles or sharp corners, effectively reducing air resistance. Even if the yarn occasionally comes into contact with its surface, the smooth surface can minimize friction damage.

[0036] In an optional embodiment, the opening 6 extends from the top surface of the upper ingot container 5 to the middle of the first height section, and the opening area is less than 1 / 3 of the top surface area of ​​the upper ingot container 5.

[0037] In this way, by eliminating the traditional yarn guide arm structure, the collision and friction between the yarn and the arm can be avoided. The design of opening 6 can constrain the airflow for a certain length while allowing the yarn to pass through, preventing the airflow above from excessively disturbing the air ring.

[0038] Furthermore, the lower ingot tank 4 includes a third height section and a fourth height section. The third height section of the lower ingot tank 4 is constructed as a cylindrical structure, and the fourth height section of the lower ingot tank 4 is constructed as a frustum-shaped structure with a gradually decreasing diameter downwards.

[0039] like Figure 2 As shown, the second height section of the upper ingot tank 5 and the third height section of the lower ingot tank 4 have the same diameter, and the diameter is less than 220mm. The height of the fourth height section is greater than 1 / 2 of the height of the lower ingot tank 4.

[0040] Preferably, the diameters of the second height section of the upper ingot tank 5 and the third height section of the lower ingot tank 4 are 205-210 mm.

[0041] Thus, the second height section of the upper tank 5 and the third height section of the lower spindle tank 4 have the same diameter, forming a continuous cylindrical surface. The air ring formed runs stably on the outside of the cylindrical surface. By using a smaller diameter, the maximum diameter of the yarn air ring is reduced, which means that the volume of air swept by the air ring when it rotates is smaller, and the energy required to overcome air resistance is significantly reduced, so as to achieve the purpose of energy saving. In addition, this compact air ring shape is more stable and less prone to drifting and shaking.

[0042] In a specific embodiment, the height of the upper ingot container 5 is 275mm, the height of the lower ingot container 4 is 160mm, the height L1 of the first height section of the upper ingot container 5 is 50-55mm, and the height L3 of the third height section of the lower ingot container 4 is 50-55mm.

[0043] In this way, the extended truncated cone structure (the fourth height section is about 100mm long) can guide and constrain the air ring more smoothly and fully, making the transition of the air ring shape from the twisting disc to the cylindrical section smoother and more natural. Its outline closely matches the natural shape of the yarn air ring when rotating at high speed. This not only stabilizes the air ring and reduces energy loss, but also ensures that the lower part of the air ring maintains a uniform gap with the surface of the spindle can, avoiding friction between the yarn and the can.

[0044] Furthermore, the lower spindle tank 4 is equipped with a yarn loading tray 3, which is located at the upper part of the fourth height section. The yarn loading tray 3 is equipped with a yarn loading bobbin, and the upper part of the yarn loading bobbin extends to the first height section of the upper spindle tank 5.

[0045] Thus, setting a higher unwinding point helps to form a slimmer, longer air ring shape, reduce the diameter of the air ring, reduce energy consumption, and also reduce tension fluctuations.

[0046] Combining the above embodiments, by significantly reducing the diameter of the spindle can body to 205-210mm and adopting a composite structure with a streamlined tapered upper section and a long conical lower section, the spindle can work synergistically with the high-speed rotating yarn air ring, making its shape more compact and stable. This not only minimizes the energy consumption of the air ring but also reduces the contact friction between the yarn and various parts of the spindle can, making it particularly suitable for high-quality twisting production of high-speed, fine denier industrial yarn.

[0047] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
