Description

Technical Field

[0001] The utility model relates to a yarn gripper for textile use, in particular to a magnetic conductive component on a magnetic conductive component on a yarn gripper for textile use. Background Art

[0002] The yarn gripper for textile is used in water jet looms and air jet looms. Currently, the magnetic conductive component of the yarn gripper mainly consists of a magnetic shell and an iron core.

[0003] When the magnetic shell wall is relatively thick, it is easy to deform or break when subjected to large external impact, collision or pressure, thereby affecting the structural integrity and normal working performance of the magnet, and may even cause the magnet to fail.

[0004] When the magnetic shell wall is thin, the stability of the thin magnetic shell may be slightly worse. During operation, the working state of the magnet may be unstable due to factors such as its own deformation, such as uneven magnetic field distribution and unstable magnetic force output, which affects the performance and reliability of the phase clamp.

[0005] Moreover, a thin magnetic shell may not be conducive to good heat dissipation of the magnet. When the magnet generates heat during operation, the thinner magnetic shell has relatively weak heat dissipation capacity, which may cause the temperature of the magnet to rise too quickly, affecting the performance and life of the magnet, and even posing the risk of overheating damage.

[0006] Secondly, the magnetic component lacks adjustable yarn pressure. Current yarn grippers adjust the yarn pressure by moving the entire magnetic component. However, changing the position of the gripper not only changes the yarn pressure stroke but also affects the response speed. For example, changing the yarn pressure stroke from 2mm to 4mm increases the yarn pressure, but also reduces the electromagnetic attraction, extending the yarn pressure time. This adjustment method requires disassembling the entire gripper, which also introduces certain difficulties in coaxial installation. Utility Model Content

[0007] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a magnetic conductive component on a yarn gripper for textile use.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a magnetic conductive component on a textile yarn clamp, comprising a magnetic yoke, a rear magnetic cover, an iron core, and a lubricating sleeve; the rear magnetic cover is coaxially fixed to the tail of the magnetic yoke, the iron core is coaxially fixed to the rear magnetic cover, a guide sleeve matching the lubricating sleeve is provided at the center of the iron core, the tail of the guide sleeve is provided with a threaded adjustment sub-portion, the threaded adjustment sub-portion is arranged on the outside of the rear magnetic cover, the head of the guide sleeve is provided with a magnetic attraction area, and the outer wall of the guide sleeve forms the outer side wall of the magnetic core matching the electromagnetic coil.

[0009] In the above-mentioned magnetic conductive component on the textile yarn gripper, the wall thickness of the magnetic yoke is 1 to 10 mm.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The magnetic yoke adopted by the utility model has high mechanical strength, low magnetic resistance, high magnetic conductivity efficiency and strong magnetic force, which is conducive to improving the opening response speed, and good heat dissipation performance.

[0012] The utility model further adopts a lubricating sleeve, which creates a low-friction condition for the actuator, thereby being beneficial to improving the closing response speed and the service life of the actuator.

[0013] This utility model adjusts the compression stroke of the return spring by shifting the feed adjustment member on the threaded adjustment sub-section of the iron core, further adjusting the yarn pressing force. Different yarn pressing forces can be set for different weft yarn types, greatly facilitating user adjustments. Furthermore, the return spring can be replaced with one of varying spring stiffnesses to adjust the yarn pressing force. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be described in detail below with reference to the accompanying drawings and exemplary embodiments. The following detailed description of the present invention is for illustrative purposes only and is by no means intended to limit the present invention and its applications or uses.

[0023] Reference Figure 1 、 Figure 2 As shown, the connection method of each component of the magnetic conductive assembly on the textile yarn gripper of the present invention is further explained as follows:

[0024] A magnetic conductive component on a yarn clamp for textile use includes a magnetic yoke 2, a rear magnetic cover 3, an iron core 4, and a lubricating sleeve 12; the rear magnetic cover 3 is coaxially fixed to the tail of the magnetic yoke 2, the iron core 4 is coaxially fixed to the rear magnetic cover 3, a guide sleeve 401 matching the lubricating sleeve 12 is provided at the center of the iron core 4, a threaded adjustment sub-portion 402 is provided at the tail of the guide sleeve 401 and outside the rear magnetic cover 3, a magnetic attraction area 403 is provided at the head of the guide sleeve 401, and the outer wall of the guide sleeve 401 forms an outer side wall 404 of the magnetic core matching the electromagnetic coil.

[0025] Refer to 1 and Figure 2 As shown, the magnetic conductive component described in the present invention is further elaborated as follows: the magnetic yoke 2, the rear magnetic cover 3, and the iron core 4 are composed of magnetic conductive materials. The magnetic conductive component can be integrated through the process of powder alchemy, or first processed into parts through CNC machining and then assembled. The magnetic conductive material is electrical pure iron, low carbon steel, silicon steel, 4 series stainless steel, etc. Among them, the main function of the magnetic yoke 2 is to provide a low magnetic resistance path for the magnetic flux, guide the distribution of the magnetic field, and enhance the thickness and stability of the magnetic field. Therefore, the wall thickness of the magnetic yoke 2 is 1 to 10 mm. The magnetic yoke 2 also supports and fixes the iron core 4. If the magnetic conductive component is not integrated, it is preferred to weld the yoke 2, the rear magnetic cover 3, and the iron core 4 together. However, since it is not processed in an integrated manner, a positioning ring needs to be added to the head of the iron core 4. The outer wall of the positioning ring is coaxial and in contact with the inner wall of the yoke 2, and the inner wall is in contact with the outer wall 404 of the magnetic core of the iron core 4. This can completely ensure that the iron core 4 and the yoke 2 are coaxial.

[0026] Since it is used in a textile environment, the magnetic conductive components are subjected to anti-corrosion treatment to increase their service life.

[0027] To further ensure the coaxiality of the core 4 and the yoke 2 and to secure the electromagnetic coil, a retaining ring is inserted over the core 4, securing the two together. This can be achieved by welding, gluing, or simply by overfitting. The outer wall of the retaining ring contacts or forms an overfit with the inner wall of the yoke 2. The retaining ring is made of a non-magnetic material.

[0028] Reference Figure 1 、 Figure 2 As shown, a guide sleeve 401 is provided at the center of the iron core 4 to match the lubricating sleeve 12. A threaded adjustment portion 402 is provided at the tail end of the guide sleeve 401. The threaded adjustment portion 402 can be either internally threaded or externally threaded. When the threaded adjustment portion 402 is externally threaded, the feed adjustment member is internally threaded.

[0029] The material of the lubricating sleeve 12 should be wear-resistant and able to withstand high temperatures of 70-120°C for a long time. Engineering plastics such as PEEK, PA, POM... can be preferably selected. Copper alloy tubes with self-lubricating function such as tin bronze tubes, brass tubes, or ceramic tubes can also be selected.

[0030] Reference Figure 1 、 Figure 2 As shown, the yarn pressing force is adjusted by rotating the feed adjustment member on the thread adjustment sub-part 402 according to the thickness of the weft yarn and the twist of the weft yarn.

[0031] The iron core 4 of the present invention is significantly longer than that of conventional yarn grippers. The long-lead iron core 4, due to its relatively low magnetic resistance, generates a greater magnetic flux through it, generating a stronger magnetic force. The relatively long electromagnetic coil employed in the present invention further increases the magnetic force and speeds up the gripper's response. A magnetic engagement zone 403 is provided on the iron core 4, forming an angle between 90° and 175°.

[0032] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made based on the essence of the present invention are intended to be included in the scope of protection of the present invention.
