Description

Technical Field

[0001] The present application relates to the technical field of textile machinery, and in particular to a wire insertion structure. Background Art

[0002] The original meaning of "textile" is a general term derived from spinning and weaving. However, with the continuous development and improvement of textile knowledge and disciplines, especially the emergence of technologies such as nonwoven textile materials and three-dimensional composite weaving, the field has expanded beyond traditional hand-spinning and weaving to include non-woven fabrics, modern three-dimensional weaving, and modern electrostatic nano-web technology for the production of clothing, industrial, and decorative textiles. Therefore, modern textile refers to the multi-scale structural processing technology of fibers or fiber aggregates. Winders are required in textile engineering and are specialized equipment in the textile industry. Winding, as the final step in spinning and the first step in weaving, serves as a bridge between the two processes, thus playing a crucial role in the textile industry. Winding is the first step in pre-weaving preparation and requires a specialized automatic winder. Automatic winders are textile process equipment that automatically winds bobbins spun on a spinning frame into a specific length of yarn. Winding connects smaller bobbins (or hanks) to form a larger bobbin. The capacity of a single bobbin is equivalent to that of more than twenty bobbins. The bobbins can be used for warping, twisting, weft winding, dyeing, weft yarn on shuttleless looms and knitting yarn.

[0024] like Figures 1 to 4As shown, a wire insertion structure includes a connector 1, a wire insertion assembly 2, and a wire cutting assembly 3. One end of the connector 1 is used to install the wire insertion assembly 2 and the wire cutting assembly 3, and the wire insertion assembly 2 and the wire cutting assembly 3 are respectively arranged on both sides of the connector 1;

[0025] The plug-in assembly 2 includes a plug-in piece 21. The connection position between the plug-in piece 21 and the connector 1 can be adjusted relative to the connector 1. The plug-in piece 21 is used to insert the wire end into the wire barrel.

[0026] The thread cutting component 3 is used to cut the thread and form a thread end.

[0027] This application cuts the wire through the wire cutting component 3, and then inserts the wire end into the wire reel through the wire plug-in component 21 of the wire plug-in component 2, thereby achieving the effect of automatic wire plug-in; the wire plug-in component 21 can be adjusted and connected to the connector 1. By adjusting the relative position of the wire plug-in component 21 connected to the connector 1, the wire plug-in can be achieved during the winding process of different wire reels, thereby improving applicability.

[0028] The connecting member 1 is provided with a plurality of first connecting holes 11 for connection.

[0029] The wire insertion assembly 2 or the wire cutting assembly 3 can be adjusted by being connected to different first connection holes 11 .

[0030] In order to simplify the structure, in this embodiment, the first connecting hole 11 is a threaded hole, which can be directly connected to a bolt or other threaded fastener; in other embodiments, the first connecting hole 11 can also be a round hole or a waist-shaped hole, and the fastener needs to be equipped with a limiting structure such as a nut or a snap, which will increase the difficulty of structural design and installation.

[0031] One end of the plug-in piece 21 is connected to the plate body 211, one end of the plate body 211 is connected to the plug-in piece 21, and the other end is inclined toward the side away from the connector 1; a wire hook groove 212 is also provided on the plug-in piece 21; a second connection hole 213 for connecting to the connector 1 is also provided on the plug-in piece 21.

[0032] Since one end of the plate body 211 is tilted and tilted toward the side away from the connector 1 , when the plate body 211 is attached to the rotating bobbin, the end of the plate body 211 will be embedded in the bobbin.

[0033] Before cutting the thread, the thread is hooked into the thread hooking groove 212, and during the rotation of the thread drum, the thread passes through the thread hooking groove 212 and is wound into the thread drum; after the thread is cut, the thread end will pass through the thread hooking groove 212 and be embedded into the rotating thread drum by the plate body 211 when passing through the thread hooking groove 212, thereby realizing the function of inserting the thread.

[0034] Furthermore, a first adjusting member 22 is connected between the plug-in member 21 and the connector 1, one side of the first adjusting member 22 is connected to the connector 1, and the other side of the first adjusting member 22 is connected to the plug-in member 21, and the connection position between the plug-in member 21 and the first adjusting member 22 can be adjusted relative to the first adjusting member 22, and the connection position between the first adjusting member 22 and the connector 1 can be adjusted relative to the connector 1; at least two third connecting holes 221 are provided on the first adjusting member 22.

[0035] The first adjusting member 22 connects the connector 1 and the plug-in member 21 , and can expand the range of relative movement between the connector 1 and the plug-in member 21 , thereby better adapting to wire reels of different sizes.

[0036] In this embodiment, the second connecting hole 213 and the third connecting hole 221 are both waist-shaped holes, the adjustment process is simple and convenient, and there is no restriction within the adjustable stroke, with better adaptability; in other embodiments, the second connecting hole 213 and the third connecting hole 221 can also be round holes, and the adjustment accuracy within the adjustable stroke is improved by increasing the number of the second connecting holes 213 and the third connecting holes 221, and only a few fixed positions can be adjusted, and the applicability is poor; when adjusting, it is necessary to disconnect the connection between the plug-in component 21 and the first adjustment component 22, and the adjustment process is complicated.

[0037] The cutting assembly 3 includes a fixed cutter 31, a movable cutter 32, a driving member 33 and a limiting assembly 34; the limiting assembly 34 connects the fixed cutter 31 and the movable cutter 32 to the connecting member 1; the fixed cutter 31 abuts against the connecting member 1, and one end of the fixed cutter 31 is provided with a first cutting edge 311; the movable cutter 32 is located on the side of the fixed cutter 31 away from the connecting member 1, and the end of the movable cutter 32 corresponding to the first cutting edge 311 is provided with a second cutting edge 321, and the other end is connected to the driving member 33; the driving member 33 is fixedly connected to the connecting member 1.

[0038] In this embodiment, the driving member 33 is a cylinder. In other embodiments, the driving member 33 may also be a structure capable of reciprocating motion, such as a rocker slider, a hydraulic cylinder, or a ball screw.

[0039] The driving member 33 drives the movable cutter 32 to move, and the wire is cut through the cooperation between the first blade portion 311 and the second blade portion 231 .

[0040] An external thread is provided at the top of the driving rod 331 of the driving member 33, and a connecting block 322 is provided at the end of the movable cutter 32 facing away from the second blade 321. The connecting block 322 is connected to the movable cutter 32 by one or more of the following methods: snap connection, welding, bolt connection, etc.; a fourth connecting hole is provided on the connecting block 322, and an internal thread meshing with the external thread of the driving rod 331 is provided on the fourth connecting hole. The connecting block 322 is connected to the driving rod 331 by threads, and at least one warning nut is also connected to the driving rod 331.

[0041] In order to limit the travel of the driving rod 331 , a limiting ring 332 is sleeved on the driving rod 331 to prevent other structures from being damaged due to the travel.

[0042] In the present application, in order to reduce the friction between the movable cutter 32 and the fixed cutter 31, a lubricating block 35 is provided at the end of the fixed cutter 31 away from the first blade portion 31, and the thickness of the lubricating block 35 is greater than the thickness of the fixed cutter 31, thereby avoiding direct contact between the movable cutter 32 and the fixed cutter 31 during movement, reducing the wear of the movable cutter 32 and the fixed cutter 31, and extending the service life; and the material of the lubricating block 35 is one or more of nylon, polytetrafluoroethylene, polyacetal, polyformaldehyde, polycarbonate, polyamide, polysulfone, polyimide, chlorinated polyether, polyphenylene sulfide and polyethylene terephthalate, with a low friction coefficient and less wear on the movable cutter 32.

[0043] The limiting assembly 34 includes a limiting plate 341 and a first bolt 342 for connecting the limiting plate 341 and the connecting member 1. The number of the first bolts 342 is at least two, and each first bolt 342 is sleeved with a first spring 343; one end of the first spring 343 abuts against the first bolt 342, and the other end abuts against the limiting plate 341.

[0044] The first spring 343 reduces the difficulty of assembly and ensures that the tangent assembly 3 is reliably connected to the connecting member 1 .

[0045] Furthermore, it also includes a clamping assembly 4, which includes a first clamping member 41 and a second clamping member 42, the second clamping member 42; the first clamping member 41 is connected between the movable cutter 32 and the limiting assembly 34, and the second clamping member 42 is connected to the side of the movable cutter 32 close to the first clamping member 41.

[0046] Through the cooperation of the first clamping member 41 and the second clamping member 42, one of the wire ends is clamped while the wire is cut, so as to facilitate the next winding.

[0047] The clamping assembly 4 also includes a support member 43, which is connected between the movable cutter 32 and the limiting assembly 34, and the support member 43 is located on the side of the first clamping member 41 away from the second clamping member 42; the thickness of the support member 43 is greater than the maximum thickness on the first clamping member 41; the support member 43 and the first clamping member 41 are connected by a second spring 44.

[0048] The second spring 44 is compressed during the process of clamping the thread end, which can better ensure that the thread end is clamped; and the vibration generated by the collision between the first clamping member 41 and the second clamping member 42 is also filtered by the second spring 44, reducing the direct impact between the components and extending the service life.

[0049] In this embodiment, the first clamping member 41, the second clamping member 42 and the supporting member 43 are made of one or more of nylon, polytetrafluoroethylene, polyacetal, polyformaldehyde, polycarbonate, polyamide, polysulfone, polyimide, chlorinated polyether, polyphenylene sulfide and polyethylene terephthalate, which have a low friction coefficient and cause less wear on the movable cutter 32.

[0050] The first clamping member 41 is provided with a groove 411 on the side close to the second clamping member 42, and the bottom of the groove 411 is arc-shaped; the second clamping member 42 is provided with a protrusion 421 on the side close to the first clamping member 41, and the surface of the protrusion 42 for abutting against the groove 411 is arc-shaped, and the height of the protrusion 421 is greater than or equal to the depth of the depression of the groove 411.

[0051] The use of the curved surface can prevent the first clamping member 41 and the second clamping member 42 from cutting the wire during the clamping process.

[0052] In this embodiment, the height of the protrusion 421 is equal to the depth of the depression of the groove 411, and the wire may still be pinched off at the intersection of the arc surface and the plane; in other embodiments, the height of the protrusion 421 is greater than the depth of the depression of the groove 411, and the intersection of the arc surface and the plane will not be squeezed, so the wire will not be pinched off.

[0053] Preferably, the second clamping member 42 is fixedly connected to the movable cutter 32 via a fixing structure, and the fixing structure includes at least one fastener 441 and / or at least one positioning member 442 .

[0054] In this embodiment, the fastener 441 is a bolt or a screw, and the positioning member 442 is a pin; in other embodiments, the positioning member 442 may also be a buckle or a slot.

[0055] In this embodiment, a fastener 441 and a positioning member 442 are used to fix the second clamping member 42 to the movable cutter 32; when fixing, the second clamping member 42 is first positioned with the positioning member 442, and then rotated to a suitable position and fixed with the fastener 441. The fixing process is simple and convenient.

[0056] In another embodiment, at least two fasteners 441 can be used for fixing; taking the two fasteners 441 as an example, when fixing, it is necessary to first use one fastener 441 for preliminary tightening to ensure that the second clamping member 42 can rotate but cannot move, and then rotate it to the appropriate position and fix it with the second fastener 441, and then tighten the first fastener 441; the fixing process is relatively cumbersome, and the threaded engagement process of the first fastener may cause the second clamping member 42 and the movable cutter 32 to offset, resulting in substandard assembly between the two.

[0057] In another embodiment, at least two positioning members 442 can be used for fixing; taking two positioning members 442 as an example, the two positioning members 442 must be able to intersect on the projection plane. When fixing, the second clamping member 42 is placed in a suitable position and the two positioning members 442 are inserted. This method is convenient for assembly, but the reliability is not good, and the second clamping member 42 may detach from the movable cutter 32.

[0058] It should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, it should be understood by those skilled in the art that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
