Description

Technical Field

[0001] The present invention relates to the technical field of weft knitting, and in particular to a yarn feeding nozzle adjustment and fixing structure, a circular loom structure and a circular loom. Background Art

[0002] Circular knitting machine, scientifically known as circular weft knitting machine (or circular weft knitting machine, circular loom). During the knitting process of existing circular knitting machines, the fixed position of the yarn feeder needs to be adjusted to meet the corresponding knitting requirements. Figure 1 、 Figure 2 As shown, existing large circular knitting machines usually adopt a method of opening a threaded hole on the top of the yarn feeding seat and using a fixing screw to fix and adjust the yarn feeding seat and the yarn feeding nozzle.

[0003] However, although the above technical solution can realize the fixation and adjustment of the yarn feeding mouth, in the process of fixing the yarn feeding mouth by adjusting the fixing screw, the circumferential torque of the fixing screw is likely to cause the yarn feeding seat as a whole to deviate circumferentially along the torque direction, resulting in the synchronous circumferential deviation of the yarn feeding mouth, which requires additional adjustment of the screw for correction. Not only is the correction process cumbersome, but the correction accuracy cannot be guaranteed.

[0004] It should be noted that the information disclosed in this background technology section is only intended to increase understanding of the overall background of the present invention, and should not be regarded as an admission or any form of implication that the information constitutes prior art already known to those skilled in the art. Summary of the Invention

[0005] In order to solve the problem that the yarn feeding nozzle of the above-mentioned existing circular loom is easily caused to circumferential offset when fixing and adjusting the yarn feeding nozzle, and the correction is cumbersome and the correction accuracy is low, the present invention provides a yarn feeding nozzle adjustment and fixing structure, which includes a yarn feeding ring, a yarn feeding seat and a locking assembly.

[0006] The yarn feeding seat has an inlay on the side facing the yarn feeding ring, and the inlay is movably connected to the yarn feeding ring. The locking assembly includes a locking slide and a locking piece, and the locking slide is located in the inlay. The locking slide is movably connected to the inlay through an inlay inclined surface, and the locking slide is movably connected to the yarn feeding ring. The locking piece passes through the yarn feeding seat from the end face of the yarn feeding seat away from the inlay and is transmission connected to the locking slide, and the locking piece can drive the locking slide to move relative to the inlay.

[0007] Furthermore, an end of the engaging inclined surface close to the yarn feeding seat is lower than an end of the engaging inclined surface away from the yarn feeding seat.

[0008] Furthermore, the angle α of the engaging slope is 15° to 25°.

[0009] Furthermore, the locking assembly also includes a spring, the locking slide is provided with a spring groove, the spring is located in the spring groove and is sleeved on the locking member, and the two ends of the spring are respectively in contact with the locking slide and the yarn feeding seat.

[0010] Furthermore, the poundage of the spring is inversely proportional to the angle α of the engaging inclined surface.

[0011] Furthermore, the yarn feeding nozzle adjustment and fixing structure further comprises a yarn feeding nozzle, and the yarn feeding nozzle is movably connected to the yarn feeding seat.

[0012] Furthermore, the present invention also provides a circular loom structure, comprising any one of the above-mentioned yarn feeding nozzle adjustment and fixing structures.

[0013] Furthermore, the present invention also provides a circular loom comprising the above-mentioned circular loom structure.

[0014] Based on the above, the present invention provides a yarn feeding nozzle adjustment and fixing structure, a circular loom structure and a circular loom. Compared with the prior art, the locking part is designed to pass through the yarn feeding seat from the end face of the side of the yarn feeding seat away from the yarn feeding ring, and is transmission-connected to the locking slide located in the embedded mouth. The locking slide is driven to move by the locking part, and cooperates with the engaging inclined surface to synchronously squeeze the yarn feeding ring to fix the yarn feeding seat when the locking slide moves relative to the yarn feeding seat, thereby changing the direction of the torque applied during the fixing process, avoiding the problem of circumferential offset of the yarn feeding seat, and eliminating the need for complicated correction operations. It is simple and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Reference numerals: DETAILED DESCRIPTION

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance, or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more. In addition, the term "including" and any variations thereof all mean "at least including".

[0020] In order to fully explain the technical solution of this application, the adjustment principle and process in the prior art are first explained. Figure 1 and Figure 2 As shown, in the technical solution of the prior art, the yarn feeding nozzle is installed on the yarn feeding ring through a yarn feeding seat, and a threaded hole is opened on the top of the yarn feeding seat. A fixing screw passes through the top threaded hole and is tightened against the yarn feeding ring, thereby fixing the yarn feeding seat relatively to the yarn feeding ring.

[0021] However, during the actual locking process, it is necessary to apply a circumferential rotational force to the fixed screw to drive the fixed screw to rotate, so that the threaded fit between the fixed screw and the yarn feeding seat causes the fixed screw to move downward and press against the yarn feeding ring. However, as the fixed screw contacts the yarn feeding ring, the circumferential force applied to the fixed screw may act synchronously on the yarn feeding seat, causing the yarn feeding seat to have a circumferential offset in the direction of the torque. At this time, in order to correct the yarn feeding seat, it can only be corrected by manual visual observation and manual adjustment of the two adjustment screws. However, in actual operation, the correction process is very cumbersome, and the correction accuracy is also relatively low, resulting in errors in weaving.

[0022] In order to solve the technical problems in the above-mentioned conventional circular looms in which the yarn feeder is easily offset in the circumferential direction when fixing and adjusting the yarn feeder, the correction is cumbersome, and the correction accuracy is low, or to achieve at least one of the above-mentioned advantages or other advantages, one embodiment of the present invention provides a yarn feeder adjustment and fixing structure.

[0023] See also Figure 3 and Figure 4 , Figure 3 A schematic structural diagram of a yarn feeding nozzle adjustment and fixing structure provided by one embodiment of the present invention; Figure 4 A schematic diagram of an exploded structure of a yarn feeding nozzle adjustment and fixing structure provided by one embodiment of the present invention.

[0024] As shown in the figure, the yarn feeding nozzle adjustment and fixing structure includes a yarn feeding ring 10, a yarn feeding seat 20 and a locking assembly 30.

[0025] The yarn feeding ring 10 can be a ring body with a flat surface. In practice, the yarn feeding ring 10 can be fixed to the circular loom using bolts or other fasteners. The yarn feeding ring 10 provides a basic mounting location for the yarn feeding seat 20. It is understood that multiple yarn feeding seats 20 can be arranged on the yarn feeding ring 10, and the specific number can be adjusted according to actual equipment and production requirements, all of which are within the scope of protection of this application.

[0026] The yarn feeding seat 20 has an insert 21 on the side facing the yarn feeding ring 10. In practice, the yarn feeding seat 20 engages with the yarn feeding ring 10 via the insert 21 and is locked with a locking assembly 30, thereby securing the yarn feeding seat 20. The locking assembly 30 can also be adjusted to release the lock between the yarn feeding seat 20 and the yarn feeding ring 10, allowing the position of the yarn feeding seat to be adjusted according to actual production needs.

[0027] The locking assembly 30 includes a locking slide 31 and a locking member 32. The locking slide 31 is positioned within the indentation 21. The locking slide 31 is movably connected to the indentation 21 via an engaging bevel 40. The locking slide 31 is movably connected to the yarn feeder ring 10. The locking member 32 extends through the yarn feeder 20 from the end face thereof facing away from the indentation 21 and is in transmission connection with the locking slide 31, enabling the locking member 32 to move the locking slide 31 relative to the indentation 21.

[0028] Preferably, a conventional transmission connection scheme can be employed between the locking member 32 and the locking slide 31. This embodiment uses a threaded transmission as an example. In practice, the locking slide 31 is movably disposed within the inlay 21 and is slidably connected to the top of the inlay 21 via an engaging bevel 40. The locking member 32 extends from the end face of the yarn feeding seat 20 facing away from the inlay 21, penetrates the yarn feeding seat 20, and is transmission-connected to the locking slide 31.

[0029] Taking the figure as an example, by adjusting the locking piece 32, the locking slide 31 can be driven to move relative to the yarn feeding seat 20 along the setting direction of the locking piece 32, and at the same time, the engaging inclined surface 40 causes the locking slide 31 to squeeze the yarn feeding ring 10, thereby realizing the locking and release between the yarn feeding seat 20 and the yarn feeding ring 10, which is convenient for adjusting and fixing the position of the yarn feeding seat 20 to meet different production needs.

[0030] Preferably, the end of the engaging bevel 40 close to the yarn feeding seat 20 is lower than the end of the engaging bevel 40 away from the yarn feeding seat 20. When the locking member 32 drives the locking slide 31 to move toward the yarn feeding seat 20, the end of the engaging bevel 40 close to the yarn feeding seat 20 is lower than the other end of the engaging bevel 40, which prompts the locking slide 31 to move downward synchronously, squeezing the yarn feeding ring 10, thereby fixing the yarn feeding seat 20.

[0031] When the locking member 32 drives the locking slide 31 to move away from the yarn feeding seat 20 , the locking slide 31 cooperates with the engaging inclined surface 40 to move upward and disengage from the yarn feeding ring 10 , thereby releasing the yarn feeding seat 20 .

[0032] Of course, the setting position of the locking slide 31 and the setting direction of the engaging bevel 40 can be adjusted according to actual needs. For example, the locking slide 31 is configured to be slidably connected to the bottom end of the inlay 21. At this time, the setting direction of the engaging bevel 40 needs to be adjusted synchronously, which is all within the protection scope of this application.

[0033] In some preferred embodiments, the angle α of the engaging slope 40 is 15° to 25°, which can ensure that the locking slide 31 can stably squeeze the yarn feeding ring 10 and smoothly slide the locking slide 31 when the yarn feeding seat 20 needs to be released. If the angle α of the engaging slope 40 is less than 15°, when the yarn feeding seat 20 needs to be released, the locking slide 31 will encounter greater resistance when moving away from the yarn feeding seat 20, and may even cause self-locking problems, resulting in the yarn feeding seat 20 being unable to be released smoothly.

[0034] If the angle α of the engaging inclined surface 40 is greater than 25°, the squeezing force of the locking slide 31 on the yarn feeding ring 10 cannot be guaranteed during locking, resulting in loosening and unstable locking.

[0035] In some preferred embodiments, the locking assembly 30 further includes a spring 33. The locking slide 31 has a spring slot 34. The spring 33 is located in the spring slot 34 and is sleeved on the locking member 32. The two ends of the spring 33 respectively abut the locking slide 31 and the yarn feeding seat 20.

[0036] In a specific embodiment, the spring 33 is disposed in the spring slot 34 and is sleeved on the locking member 32. The two ends of the spring 33 respectively abut the locking slide 31 and the yarn feeding seat 20. When the locking member 32 drives the locking slide 31 toward the yarn feeding seat 20, it compresses the spring 33, accumulating elastic potential energy.

[0037] When the yarn feeding seat 20 needs to be released, the locking piece 32 drives the locking slide 31 to move in the direction away from the yarn feeding seat 20, and the squeezing force of the locking slide 31 on the spring 33 is reduced. The elastic potential energy of the spring 33 is converted into kinetic energy, pushing the locking slide 31 to move in the direction away from the yarn feeding seat 20, thereby facilitating the release of the yarn feeding seat 20.

[0038] Based on the above, the poundage of the spring 33 is inversely proportional to the angle α of the fitting slope 40. That is, the larger the angle α of the fitting slope 40, the smaller the poundage of the spring 33.

[0039] Furthermore, the yarn feeding nozzle adjustment fixing structure further includes a yarn feeding nozzle 50. The yarn feeding nozzle 50 is movably connected to the yarn feeding seat 20. The yarn feeding nozzle 50 can be a conventional yarn feeding nozzle in the prior art, which is used to feed the yarn into the knitting needles for knitting. In some preferred embodiments, the present invention further provides a circular loom structure comprising any one of the above-mentioned yarn feeding nozzle adjustment and fixing structures.

[0040] In some preferred embodiments, the present invention further provides a circular loom comprising the above-mentioned circular loom structure.

[0041] To sum up, the present invention provides a yarn feeding mouth adjustment and fixing structure, a circular loom structure and a circular loom. Compared with the prior art, the locking piece is designed to pass through the yarn feeding seat from the end face of the side of the yarn feeding seat away from the yarn feeding ring, and is transmission-connected with the locking slide located in the embedded mouth. The locking slide is driven to move by the locking piece, and cooperates with the engaging inclined surface to synchronously squeeze the yarn feeding ring to fix the yarn feeding seat when the locking slide moves relative to the yarn feeding seat, thereby changing the direction of the torque applied during the fixing process, avoiding the problem of circumferential offset of the yarn feeding seat, and eliminating the need for complicated correction operations. It is simple and quick.

These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
