Description

Technical Field

[0001] This utility model belongs to the field of yarn clamping technology, and in particular relates to a yarn clamping device for textile machinery. Background Technology

[0002] In the field of textile machinery, yarn clamps are the core components for achieving precise clamping and release of yarn. Their main function is to clamp and release yarn. However, most yarn clamps are driven by mechanical springs, which has obvious drawbacks. Due to long-term reciprocating motion, the springs are prone to aging and breakage, resulting in a short service life for the yarn clamps and affecting the efficiency of textile machinery and product quality. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a yarn clamp for textile machinery. Through the cooperation of coil, magnet and magnetic body, the principle of like poles repulsion of magnets is used to replace the reciprocating motion of spring. When the coil is energized, a magnetic field is generated, which drives the shaft core to move linearly. When the coil is de-energized, the magnetic field disappears, and the magnetic repulsion force between the magnet and the magnetic body drives the shaft core to move linearly in the opposite direction and then reset. This realizes the reciprocating linear motion of the shaft core and extends the service life of the yarn clamp.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A yarn clamp for a textile machine includes a housing and a shaft, the shaft being movably disposed within the housing. The device is characterized by further including a coil, a magnet, and a sleeve. The sleeve is fitted onto the shaft and is used to restrict the movement path of the shaft. The magnet is installed within the housing, and the shaft passes through the magnet. The shaft is provided with a magnetic body, which generates a repulsive magnetic force with the magnet. The coil is arranged around the shaft.

[0006] When the coil is energized, it drives the shaft to move linearly. When the coil is de-energized, the magnet drives the shaft to move linearly in the opposite direction, thus realizing the reciprocating linear motion of the shaft.

[0007] By combining a coil, a magnet, and a magnetic body, and utilizing the principle of like poles repulsion of the magnet, the reciprocating motion of the spring is replaced. When the coil is energized, a magnetic field is generated, which drives the shaft to move linearly. When the coil is de-energized, the magnetic field disappears, and the magnetic repulsion between the magnet and the magnetic body drives the shaft to move linearly in the opposite direction and then reset. This achieves the reciprocating linear motion of the shaft and extends the service life of the wire clamp.

[0008] Furthermore, the sleeve is provided with a through slot, through which the shaft passes. The through slot guides the movement of the shaft, preventing it from shifting during movement. The diameter of the through slot is smaller than the outer diameter of the magnet, preventing the shaft from coming out of the sleeve.

[0009] Furthermore, a shim is installed at the end of the sleeve that contacts the shaft core. The shim is used to prevent the magnetic body from colliding with the sleeve. The shim acts as a buffer to absorb the impact energy between the magnetic body and the sleeve, preventing the magnetic body from breaking and extending the life of the core component.

[0010] Furthermore, a magnet holder is installed inside the housing. The magnet holder is used to limit the magnet, prevent the magnet from shifting or flipping under strong magnetic field conditions, and maintain the symmetry of the magnetic circuit.

[0011] Furthermore, it also includes a wire clamping assembly, which includes a wire clamping seat and a wire clamping head disposed at the end of the shaft core. The shaft core drives the wire clamping head to reciprocate and cooperate with the wire clamping seat to clamp the wire.

[0012] Furthermore, both the clamping head and the clamping seat are provided with mounting slots for installing clamping pads. The mounting slots of the clamping head and the clamping seat enable quick replacement of the clamping pads. The design of the clamping pads avoids damage to the yarn during clamping operations.

[0013] Furthermore, both the housing and the wire clamp seat are provided with fixing holes, and the housing and the wire clamp seat are fixed to the base plate through the fixing holes.

[0014] Furthermore, the base plate is provided with a bending plate one and a bending plate two. The bending plate one is provided with a wire inlet, and the bending plate two is provided with a wire outlet.

[0015] Furthermore, the housing is equipped with an end cap, and the housing and the end cap are provided with corresponding mounting holes, which allow the housing and the end cap to be detachably connected.

[0016] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0017] This invention utilizes the combination of a coil, a magnet, and a magnetic body, taking advantage of the repulsion principle of like poles of the magnet to replace the reciprocating motion of the spring. When the coil is energized, a magnetic field is generated, which drives the shaft core to move linearly. When the coil is de-energized, the magnetic field disappears, and the magnetic repulsion force between the magnet and the magnetic body drives the shaft core to move linearly in the opposite direction and then reset, thereby realizing the reciprocating linear motion of the shaft core and extending the service life of the wire clamp.

Detailed Implementation

[0025] like Figures 1 to 5 As shown, this utility model provides a yarn clamp for a textile machine, which includes a base plate 14, a housing 1, a shaft core 2, a coil 3, a magnet 4, a sleeve 5, and a yarn clamping assembly. The yarn clamping assembly includes a yarn clamping seat 10 and a yarn clamping head 11 disposed at the end of the shaft core 2. A space is reserved between the yarn clamping head 11 and the yarn clamping seat 10.

[0026] The housing 1 is equipped with an end cap 19. The housing 1 and the end cap 19 are respectively provided with mounting holes 20. The housing 1 and the end cap 19 are detachably connected through the mounting holes 20. The housing 1 and the wire clamping seat 10 are both provided with fixing holes 13. The housing 1 and the wire clamping seat 10 are fixed to the base plate 14 through the fixing holes 13. The base plate 14 is provided with a bending plate 15 and a bending plate 16. The bending plate 15 is provided with a wire inlet 17, and the bending plate 16 is provided with a wire outlet 18. The yarn enters from the wire inlet 17, passes through the reserved space between the wire clamping head 11 and the wire clamping seat 10, and the shaft core 2 drives the wire clamping head 11 to reciprocate and cooperate with the wire clamping seat 10 to clamp the yarn. After completion, the yarn leaves the wire clamping device from the wire outlet 18.

[0027] Both the clamping head 11 and the clamping seat 10 are provided with mounting slots 12. The mounting slots 12 are used to install clamping pads (not shown in the figure). The mounting slots 12 of the clamping head 11 and the clamping seat 10 enable quick replacement of clamping pads. The design of the clamping pads avoids damage to the yarn during clamping operations.

[0028] In this embodiment, the housing 1 is provided with two sets, located on both sides of the wire clamping seat 10, in order to improve the wire clamping efficiency.

[0029] The shaft core 2 is movably disposed within the housing 1. The sleeve 5 is fitted onto the shaft core 2 to restrict the movement path of the shaft core 2. The sleeve 5 is provided with a through slot 7 through which the shaft core 2 passes. The through slot 7 guides the movement of the shaft core 2 and prevents the shaft core 2 from deviating during movement. The diameter of the through slot 7 is smaller than the outer diameter of the magnetic body 6 to prevent the shaft core 2 from coming out of the sleeve 5.

[0030] Magnet 4 is installed inside housing 1, and shaft 2 passes through magnet 4. Shaft 2 is provided with magnetic body 6. Magnetic body 6 and magnet 4 generate a repulsive magnetic force. Coil 3 is arranged around shaft 2. Magnet seat 9 is installed inside housing 1. Magnet seat 9 is used to limit magnet 4, prevent magnet 4 from shifting or flipping in a strong magnetic field environment, and maintain magnetic circuit symmetry. When coil 3 is energized, it drives shaft 2 to move linearly. When coil 3 is de-energized, magnet 4 drives shaft 2 to move linearly in the opposite direction, thereby realizing the reciprocating linear motion of shaft 2.

[0031] By combining coil 3, magnet 4, and magnetic body 6, the principle of like poles repulsion of magnet 4 is used to replace the reciprocating motion of the spring. When coil 3 is energized, a magnetic field is generated, which drives the shaft core 2 to move linearly. When coil 3 is de-energized, the magnetic field disappears, and the magnetic repulsion between magnet 4 and magnetic body 6 drives the shaft core 2 to move linearly in the opposite direction and then reset. This achieves the reciprocating linear motion of shaft core 2 and extends the service life of the wire clamp.

[0032] Specifically, such as Figure 3 As shown, the magnetic body 6 has magnetism and the same magnetic poles as the magnet 4. When the coil 3 is de-energized, due to the principle of like poles repulsion, a magnetic repulsive force is generated between the magnet 4 and the magnetic body 6, driving the shaft core 2 to move closer to the wire clamp seat 10. When the coil 3 is energized, a magnetic field is generated. The direction of the magnetic field depends on the direction of the current. It interacts with the magnetic body 6 to generate an electromagnetic force, driving the shaft core 2 to overcome the magnetic repulsive force of the magnet 4 and move away from the wire clamp seat 10. By energizing and de-energizing the coil 3, the cycle is repeated, thereby realizing linear reciprocating motion.

[0033] Furthermore, in another embodiment, the magnetic body 6 and the magnet 4 can be configured to have different magnetic poles. When the coil 3 is de-energized, due to the principle of attraction between opposite poles, a magnetic attraction force is generated between the magnet 4 and the magnetic body 6, driving the shaft core 2 to move away from the wire clamp seat 10. When the coil 3 is energized, a magnetic field is generated. The direction of the magnetic field depends on the direction of the current. It interacts with the magnetic body 6 to generate an electromagnetic force, driving the shaft core 2 to overcome the magnetic attraction force of the magnet 4 and move towards the wire clamp seat 10. By energizing and de-energizing the coil 3, the cycle is repeated, thereby realizing linear reciprocating motion.

[0034] A washer 8 is installed at the end of the sleeve 5 that contacts the shaft core 2. The washer 8 is used to block the collision between the magnetic body 6 and the sleeve 5. The washer 8 acts as a buffer to absorb the impact energy between the magnetic body 6 and the sleeve 5, so as to prevent the magnetic body 6 from breaking and extend the life of the core component.

[0035] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
