Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a spindle structure for a mechanical covering yarn machine. Background Technology

[0002] As equipment for producing covered yarn, the operational stability and production efficiency of mechanical covering yarn machines directly determine the quality of the covered yarn products and the production benefits of enterprises. The spindle, as the core actuator of the mechanical covering yarn machine, mainly undertakes functions such as yarn winding, unwinding, and forming the yarn covering process.

[0003] Currently, in traditional coating machine spindle structures, to achieve synchronous rotation of the yarn sleeve and spindle rod, a plug is typically installed at the bottom of the spindle rod, and the yarn sleeve is fitted onto the spindle rod, forming an insertion fit between the bottom of the yarn sleeve and the plug. During the insertion process, to reduce the clearance between the two, the operator needs to apply considerable downward pressure to tighten the yarn sleeve and plug into place, increasing labor intensity.

[0004] On the other hand, after the production of a roll of yarn is completed, the yarn sleeve needs to be removed from the spindle and replaced. Due to the above installation method, the tightness of the insertion fit is relatively high. It is difficult to pull out the yarn sleeve directly by hand. The operator needs to use special tools such as prying tools to pry from the bottom of the yarn sleeve to separate the yarn sleeve from the plug more easily. This separation operation is relatively cumbersome. Utility Model Content

[0005] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, this invention proposes a spindle structure for a mechanically covering yarn machine.

[0006] The technical solution to the technical problem solved by this utility model is as follows: This utility model proposes a spindle structure for a mechanically covered yarn machine, including a spindle base with a rotatable spindle rod connected to the top. A yarn sleeve and a locking head are fitted onto the spindle rod. The locking head is detachably connected to the spindle rod and is positioned above the yarn sleeve. The machine also includes a plug fitted onto the lower part of the spindle rod, with at least one set of positioning holes on its side wall. A tube is connected to the bottom of the yarn sleeve and inserted into the upper part of the plug. A control button is connected to the outer wall of the tube. The output end of the control button passes through the tube and is connected to a telescopic rod, which is inserted into the positioning hole and can be extended from the positioning hole by means of the control button.

[0007] Preferably, the control button includes an outer cylinder, a button cap slidably connected inside the outer cylinder, a fixed cylinder connected to the bottom wall of the outer cylinder, one end of the telescopic rod being connected to the inner wall of the button cap by means of a first spring, and the other end passing through the outer cylinder along the axial direction of the fixed cylinder and being inserted into a positioning hole; it also includes a trigger unit disposed inside the outer cylinder and the button cap, the trigger unit being used to drive the telescopic rod to slide back inside the fixed cylinder when the button cap is pressed.

[0008] Preferably, the driving unit includes two sets of wedges connected to the inner wall of the cap, the opposite sides of the two wedges being inclined and arranged parallel to each other; the telescopic rod has an oblique through hole, and the fixed cylinder has movable openings on both sides, the movable openings communicating with the through hole; it also includes an obliquely arranged guide rod, the two ends of the guide rod passing through the through hole and the movable opening respectively, and connected to a sliding block, the sliding block and the driving rod together forming a "Z"-shaped driving rod, the outer wall of the sliding block having an inclined surface adapted to abut against the wedge, and being able to slide along the inclined direction of the wedge; when the cap is pressed, the two wedges drive the driving rod to move along the inclined surface during the downward movement, driving the telescopic rod to retract along the fixed cylinder.

[0009] Preferably, a rotatable spindle disk is connected above the spindle seat, and a braking part is connected above the spindle disk. The braking part is sleeved on the outside of the spindle rod, and the plug is located between the braking part and the yarn sleeve.

[0010] Preferably, the braking unit includes a drive cylinder fixed above the piston disc, and the spindle is located inside the drive cylinder.

[0011] It also includes a second spring, which is sleeved outside the spindle and located inside the drive cylinder. The bottom of the second spring is connected to the spindle disc, and the top of the second spring is connected to the plug.

[0012] Preferably, the plug has a stepped structure and is made of rubber, plastic, or a combination thereof.

[0013] Preferably, a limiting groove with a "J"-shaped structure is provided above the spindle, and a limiting pin is fixed inside the lock head. The limiting pin is adapted to the limiting groove and can slide along the trajectory of the limiting groove.

[0014] Preferably, the yarn sleeve has a limiting edge fixed on both the upper and lower sides.

[0015] The above technical solution has the following advantages or beneficial effects: In this invention, an insert is fixed at the bottom of the yarn sleeve, and a control button and a telescopic rod are provided inside the insert, which cooperate with the positioning hole opened in the plug. During disassembly, the telescopic rod can be disengaged from the positioning hole simply by operating the control button, without the need for tools.

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0025] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] like Figure 1 or Figure 5 As shown, this embodiment proposes a spindle structure for a mechanically covered yarn machine, including a spindle base 1, a rotatable spindle rod 2 connected above the spindle base 1, a yarn sleeve 3 and a locking head 4 sleeved on the top rod, the locking head 4 being detachably connected to the top rod and located above the yarn sleeve 3 to constrain the yarn sleeve 3 and enhance the stability of the yarn sleeve 3 during rotation.

[0027] It also includes a plug 5, which is sleeved and connected to the lower part of the top rod, and at least one set of positioning holes 6 are opened on the side wall of the plug 5; a tube 7 is fixedly connected to the bottom of the yarn sleeve 3, which is adapted to be inserted into the upper part of the plug 5, and a control button 8 is also connected to the outer wall of the tube 7. The output end of the control button 8 passes through the tube 7 and is connected to a telescopic rod 9. In the normal state, the telescopic rod 9 is inserted into the positioning hole 6. When it is necessary to remove the yarn sleeve 3, the telescopic rod 9 can be extended from the positioning hole 6 by means of the control button 8.

[0028] Compared to traditional methods of installation by pressing down hard and disassembly by prying with tools, this application adopts a design that coordinates the control button 8, the telescopic rod 9, and the positioning hole 6. During disassembly, only the control button 8 needs to be operated to disengage the telescopic rod 9 from the positioning hole 6 without the need for tools. During installation, after the insert 7 is inserted into the plug 5, the telescopic rod 9 automatically snaps into the positioning hole 6, thereby significantly shortening the replacement time of the yarn sleeve.

[0029] On the other hand, traditional plug-in connection methods may lead to problems such as loosening between the plug 5 and the yarn sleeve after a certain period of operation. This plug-in connection forms a mechanical lock, which can enhance the stability between the yarn sleeve and the plug 5 and reduce the possibility of relative slippage between them.

[0030] In some embodiments, the control button 8 includes an outer cylinder 81, a button cap 82 slidably connected inside the outer cylinder 81, and a fixed cylinder 83 connected to the bottom of the outer cylinder 81. One end of the telescopic rod 9 is connected to the inside of the button cap 82 by means of a first spring 84, and the other end passes through the outer cylinder 81 along the fixed cylinder 83 and is inserted into the positioning hole 6. A trigger unit is also included inside the outer cylinder 81 and the button cap 82. This trigger unit is used to drive the telescopic rod 9 to slide back within the fixed cylinder 83 when the button cap 82 is pressed.

[0031] The design of the lower control button 8 allows for easier one-handed operation during the assembly and disassembly of the yarn sleeve 3. Specifically, in the normal state, the elastic force of the first spring 84 keeps the telescopic rod 9 in the extended position; during installation, refer to... Figure 5 Hold the yarn sleeve with your thumb and forefinger, and press the cap 82 with your thumb to trigger the telescopic rod 9 to retract. Then, place the yarn sleeve onto the spindle rod 2, so that the insert 7 is inserted into the upper part of the plug 5. After releasing your thumb, rotate the yarn sleeve until the telescopic rod 9 is aligned with the positioning hole 6. Figure 5 As indicated by the arrow in the diagram, the button 82 pops out to the left under the force of the first spring 84, and the telescopic rod 9 automatically pops out and engages with the positioning hole 6 as the button 82 moves, thus completing the rapid positioning of the yarn sleeve.

[0032] This one-handed operation method, compared to the manual pressing and tool prying disassembly process, can further shorten the yarn sleeve replacement time, and is especially suitable for high-frequency replacement production scenarios in covering yarn machines. Moreover, relying on the characteristics of the first spring 84, the telescopic rod 9 can remain extended after being inserted into the positioning hole 6, effectively preventing the telescopic rod 9 from coming out of the positioning hole 6 during spindle rotation.

[0033] Furthermore, the drive unit includes two sets of wedges 85 connected inside the cap 82. The two sets of wedges 85 are located on both sides of the bottom of the cap 82, creating a space between them. The opposite sides of the two sets of wedges 85 are inclined and arranged parallel to each other. An oblique through hole 86 is opened inside the telescopic rod 9. Movable openings 87 are opened on both sides of the fixed cylinder 83. The movable openings 87 are connected to the through hole 86, and the diameter of the movable opening is larger than the diameter of the through hole 86, providing space for the drive rod 88. It also includes an obliquely arranged guide rod. The two ends of the guide rod pass through the through hole 86 and the movable opening 87 respectively and are connected to sliding blocks. The two sliding blocks and the drive rod 88 in the middle together form a "Z"-shaped drive rod 88. The outer wall of the sliding block has an oblique edge that fits and abuts against the wedge 85, and the sliding block can slide along the inclined direction of the wedge 85.

[0034] During operation, when the cap 82 is pressed, the two wedges 85 move downwards, squeezing and pushing the drive rod 88 between them. This causes the drive rod 88 to move along the inclined plane. During this movement, the inclined guide rod drives the telescopic rod 9 to move to the left, causing it to retract axially along the fixed cylinder 83, thus achieving the desired effect. Figure 5 The state in.

[0035] In some embodiments, a rotatable spindle disc 10 is mounted above the spindle base 1, and a braking part is connected above the spindle disc 10. The braking part is sleeved outside the spindle rod 2, and the aforementioned plug 5 is located between the braking part and the yarn sleeve. The spindle disc 10 serves as a carrier, and components such as the spindle rod 2 are integrated and connected above it. The braking part undertakes the power transmission function, which is used to drive the spindle disc 10 and the components above it to rotate synchronously, ultimately realizing the yarn wrapping operation.

[0036] Furthermore, the braking unit is a driven component, obtaining power from the drive equipment of the covering yarn machine, thereby driving the spindle disc 10 and the components above it to rotate. This braking unit includes a drive cylinder 11 fixed above the spindle disc 10, with the aforementioned spindle rod 2 passing through the drive cylinder 11. In practical applications, to achieve synchronous operation of multiple spindles, a belt drive is often used. The outer wall of the drive cylinder 11 is in contact with the drive belt, and the friction between the two drives the drive cylinder 11 to rotate, thereby coordinating the synchronous rotation of the spindle disc 10 and the spindle rod 2, yarn sleeves, and other components above it, ensuring the continuity and stability of covered yarn production.

[0037] In some embodiments, a second spring 12 is also included. The second spring 12 is sleeved outside the spindle 2 and located inside the drive cylinder 11. The bottom of the second spring 12 is connected to the spindle disc 10, and the top of the second spring 12 is connected to the plug 5. The second spring 12 has an appropriate elastic stiffness and provides support under normal conditions. In some special cases, it can absorb external impact forces, thereby preventing hard collisions between the plug 5 and the drive cylinder 11. On the other hand, under the force of the second spring 12, an upward thrust can be generated on the plug 5 and the installed yarn sleeve 3. In conjunction with the upper locking head 4, the yarn sleeve 3 is positioned between the locking head 4 and the plug 5, improving the stability of the yarn sleeve 3 during installation or rotation.

[0038] In some embodiments, the plug 5 has a stepped structure and is made of rubber, plastic, or a combination thereof. This structure and material can reduce the gap between the insert 7 and the plug 5 during insertion, thereby making the connection between the yarn sleeve 3 and the plug 5 more stable.

[0039] refer to Figure 5In some embodiments, a J-shaped limiting groove 13 is provided above the spindle 2, and a limiting pin 14 is fixed inside the locking head 4. The limiting pin 14 is adapted to and inserted into the limiting groove 13 and can slide along the trajectory of the limiting groove 13. After the yarn sleeve 3 is installed, the locking head 4 is fitted onto the top of the top rod, and the limiting pin 14 can rotate along the path of the limiting groove 13, thereby fixing it to the end position of the limiting groove 13, so as to quickly achieve the installation and positioning of the locking head 4.

[0040] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
