Fully automatic anti-rotation fabric yarn-blocking device

Abstract

This invention relates to the field of knitting, specifically to a fully automatic anti-rotation yarn-blocking device, comprising a knitting machine body, a needle bed, a knitting head, a slide rail, and a moving mechanism. A yarn feeding mechanism is mounted on the slide rail, and a clamping mechanism is mounted on the yarn feeding mechanism. A pop-out mechanism, which works in conjunction with the clamping mechanism, is located on the knitting head. The yarn feeding mechanism includes a slider slidably mounted on the slide rail, with a support plate fixed to the slider. A bundle of yarn and a yarn feed head are sequentially mounted on the support plate. By incorporating the pop-out mechanism, the yarn feeding mechanism, and the clamping mechanism, this invention allows the clamping mechanism to release its lock on the yarn feed head during the movement of the yarn feeding mechanism. When the yarn feeding mechanism stops moving, the clamping mechanism locks the yarn feed head on it, preventing it from being pulled out during the knitting of other yarn bundles. This saves yarn, ensures the quality of the knitted fabric, and achieves full automation, improving production efficiency, reducing labor input, and better meeting practical needs.

Description

Technical Field

[0001] This invention relates to the field of weaving technology, specifically to a fully automatic anti-rotation yarn-segmentation device. Background Technology

[0002] The types of raw materials that can be used with braiding machines include: nylon multifilament, polypropylene, polyester, cotton yarn, pearl yarn, etc. A set of head yarns is present on the braiding machine; this set of head yarns serves to connect the fabrics being woven, thus forming a complete braid.

[0003] When this group of yarn heads is not in operation, it will still move along with other yarn bundles during the weaving process, resulting in a waste of resources. Although some devices can clamp this group of yarn heads, the overall level of automation is low, which seriously affects production efficiency. To address this, we have proposed a fully automatic anti-rotation yarn-blocking device. Summary of the Invention

[0004] (i) In view of the shortcomings of the prior art, the present invention provides a fully automatic anti-rotation yarn-blocking device, which overcomes the problem of yarn routing in the existing braiding machine, achieves the function of saving yarn, and realizes full automation, improves production efficiency, reduces labor input, and can better meet actual needs.

[0005] (II) To achieve the above objectives, the present invention is implemented through the following technical solution: a fully automatic anti-rotation yarn-blocking device, comprising a braiding machine body, wherein the braiding machine body is provided with a needle bed, a knitting head adapted to the needle bed and a slide rail, and the braiding machine body is provided with a moving mechanism for driving the knitting head, wherein the slide rail is provided with a yarn feeding mechanism, wherein the yarn feeding mechanism is provided with a clamping mechanism, and wherein the knitting head is provided with a pop-out mechanism that cooperates with the clamping mechanism;

[0006] The wire feeding mechanism includes a slider that is slidably mounted on a slide rail, a support plate that is fixed on the slider, and a wire bundle and a wire feeding head that are sequentially mounted on the support plate.

[0007] The clamping mechanism includes a swing rod rotatably mounted on a support plate and a support column fixed on the support plate. A first extrusion roller and a second extrusion roller are sequentially mounted on the swing rod. A rotating plate is rotatably mounted on the support column. A return spring is installed between the rotating plate and the support column. A first stop block and a second stop block are sequentially mounted on the rotating plate to cooperate with the first extrusion roller and the second extrusion roller. A connecting rod is fixed on the rotating plate. A clamping rod to cooperate with the coil is rotatably mounted on the connecting rod. The two sections of the clamping rod have different dimensions.

[0008] Preferably, the ejection mechanism includes a cavity formed inside the machine head, a guide post fixed inside the cavity, a connecting rod slidably mounted on the guide post, and a spring sleeved on the guide post, the spring being fixed between the connecting rod and the cavity. An ejection block one and an ejection block two, slidably mounted to the cavity, are fixed on the connecting rod and are symmetrically arranged. An iron block is fixed on the connecting rod. Guide strips cooperating with ejection block one and ejection block two are symmetrically fixed to the top of the slider. A power component for controlling the lifting and lowering of the iron block is installed inside the cavity.

[0009] Preferably, the ejection mechanism further includes two sets of limiting rods fixed in the cavity and used in conjunction with the connecting rod.

[0010] Preferably, the power component is an electromagnet used in conjunction with the iron block.

[0011] Preferably, the power component includes a hydraulic rod installed in the cavity, and the movable end of the hydraulic rod is fixed with a hanging rod that cooperates with the iron block.

[0012] Preferably, the moving mechanism includes a support rod fixed to the body of the braiding machine, a slide rail is provided on the support rod, a moving block fixed to the machine head is slidably installed in the slide rail, a screw threaded on the moving block and rotatably connected to the slide rail, and a motor for driving the screw to rotate is installed on the body of the braiding machine.

[0013] Preferably, the outer diameter of one section of the clamping rod is smaller than the inner diameter of the coil, and the outer diameter of the other section of the clamping rod is larger than the inner diameter of the coil.

[0014] Preferably, the slide rail, the wire feeding mechanism, the clamping mechanism, and the ejection mechanism are provided in multiple sets.

[0015] (III) This invention provides a fully automatic anti-rotation yarn-blocking device, which has the following beneficial effects:

[0016] 1. This invention incorporates a pop-out mechanism, a feeding mechanism, and a clamping mechanism. During the movement of the feeding mechanism, the clamping mechanism releases the locking of the head thread. When the feeding mechanism stops moving, the clamping mechanism locks the head thread on it, preventing the head thread, which plays a connecting role in the weaving of other yarn bundles, from being pulled out by the yarn. This saves yarn, ensures the quality of the woven fabric, achieves full automation, improves production efficiency, reduces labor input, and better meets practical needs.

[0017] 2. By adding an ejection mechanism and a clamping mechanism, the present invention achieves the linkage between the two, resulting in a more compact overall structure. It eliminates the need for additional electrical components to lock the head wire, thus reducing costs. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] Example 1

[0031] like Figures 1-8 As shown, the fully automatic anti-rotation yarn-blocking device includes a braiding machine body 1, a needle bed 2, a knitting head 3 adapted to the needle bed 2, and a slide rail 4. The braiding machine body 1 also has a moving mechanism 7 for driving the knitting head 3. A yarn feeding mechanism 5 is mounted on the slide rail 4, and a clamping mechanism 6 is mounted on the yarn feeding mechanism 5. The knitting head 3 has a pop-out mechanism 8 that works in conjunction with the clamping mechanism 6. Controlling the moving mechanism 7 causes the knitting head 3 to move back and forth along the needle bed 2. This movement of the knitting head 3 drives the pop-out mechanism 8, the yarn feeding mechanism 5, and the clamping mechanism 6 to move back and forth. During the movement of the yarn feeding mechanism 5, the clamping mechanism 6 does not lock the yarn on it. When the yarn feeding mechanism 5 stops moving, the clamping mechanism 6 locks the yarn on it, preventing the yarn, which plays a connecting role in the braiding of other yarn bundles, from being pulled out by the following yarn. This saves yarn, ensures the quality of the woven fabric, achieves full automation, improves production efficiency, reduces labor input, and better meets practical needs.

[0032] The wire feeding mechanism 5 includes a slider 51 slidably mounted on a slide rail 4, a support plate 52 fixed on the slider 51, and a coil 54 and a wire feeding head 53 sequentially mounted on the support plate 52. The head wire is pre-passed through the coil 54 and the wire feeding head 53 sequentially. The clamping mechanism 6 includes a swing rod 61 rotatably mounted on a support plate 52 and a support column 62 fixed on the support plate 52. A first extrusion roller 67 and a second extrusion roller 68 are sequentially mounted on the swing rod 61. A rotating plate 63 is rotatably mounted on the support column 62. A return spring 64 is installed between the rotating plate 63 and the support column 62. The return spring 64 ensures that the rotating plate 63 can return to its original position after rotation. A first stop block 65 and a second stop block 66, which cooperate with the first extrusion roller 67 and the second extrusion roller 68, are sequentially mounted on the rotating plate 63. A connecting rod 69 is fixed on the rotating plate 63. A clamping rod 610, which cooperates with the coil 54, is rotatably mounted on the connecting rod 69. The two sections of the clamping rod 610 have different dimensions; specifically, the outer diameter of one section of the clamping rod 610 is smaller than the inner diameter of the coil 54, and the outer diameter of the other section of the clamping rod 610 is larger than the inner diameter of the coil 54. Figure 2To determine the up, down, left, and right orientation, the working process of the clamping mechanism 6 is described as follows: When the top of the swing rod 61 swings to the right, the bottom of the swing rod 61 swings to the left, and the first and second extrusion rollers 67 and 68 on it also swing to the left. The first extrusion roller 67 moves away from the first stop block 65, and the second extrusion roller 68 abuts against the second stop block 66 and drives the rotating plate 63 to rotate, which in turn drives the connecting rod 69 to rotate, thereby driving the clamping rod 610 to move and gradually move away from the coil 54 (in this process, the thinner section of the clamping rod 610 is still inside the coil 64, and the thicker section is separated from the coil 64). At this time, the head wire is released from the locking state, and the head wire can follow the wire during the movement of the wire feeding mechanism 5; when the swing rod 61 returns to its original position, the clamping rod 610 moves and gradually approaches the coil 54, which can lock the head wire.

[0033] Similarly, when the top of the swing rod 61 swings to the left, the bottom of the swing rod 61 swings to the right, and the first extrusion roller 67 and the second extrusion roller 68 on it also swing to the right. The second extrusion roller 68 moves away from the second stop block 66, and the first extrusion roller 67 abuts against the first stop block 65 and drives the rotating plate 63 to rotate (the two rotation directions of the rotating plate 63 are the same). The following process is the same as described above.

[0034] In this embodiment, the ejection mechanism 8 includes a cavity 81 opened within the machine head 3. The ejection mechanism 8 also includes two sets of limiting rods 87 fixed within the cavity 81 and used in conjunction with the connecting rod 82. A guide post 83 is fixed within the cavity 81, and the connecting rod 82 is slidably mounted on the guide post 83. A spring 84 is sleeved on the guide post 83, and the spring 84 is fixed between the connecting rod 82 and the cavity 81. An ejection block 1 85 and an ejection block 2 86, slidably mounted to the cavity 81, are fixed on the connecting rod 82. The ejection blocks 1 85 and 2 86 are symmetrically arranged. An iron block 88 is fixed on the connecting rod 82. Guide strips 810, which cooperate with the ejection blocks 1 85 and 2 86, are symmetrically fixed to the top of the slider 51. A power component for controlling the lifting and lowering of the iron block 88 is installed within the cavity 81. Figure 1 To determine the up, down, left, and right orientation, during the rightward movement of the machine head 3, ejector blocks 1 85 and 2 86 move to the right. Ejector block 2 86 contacts the left guide bar 810 and is squeezed upward. When ejector block 2 86 moves to the recess in the middle of the slider 51, ejector block 2 86 moves downward and engages with the swing rod 61. As the machine head 3 continues to move to the right, the top of the swing rod 61 swings to the right until the swing rod 61 abuts against the recess of the slider 51. At this time, the machine head line is released from its locked state. During the continued rightward movement of the machine head 3, the wire feeding mechanism 5 begins to feed the wire. When the machine head 3 moves to the appropriate position, the power component is activated, the iron block 88 moves upward, and ejector blocks 2 86 moves upward and away from the swing rod 61. The swing rod 61 then moves back to its original position, thus locking the machine head line. At this time, the machine head 3 will continue to move to the right until ejector block 1 85 is located on the right side of the slider 51.

[0035] Similarly, during the leftward movement of the machine head 3, the pop-out locking block 85 cooperates with the swing rod 61 to ensure that the wire feeding mechanism 5 feeds the wire normally when moving to the left. When not in operation, the wire of the machine head is locked.

[0036] In this embodiment, the moving mechanism 7 includes a support rod 71 fixed to the knitting machine body 1. A slide rail 72 is provided on the support rod 71. A moving block 75, fixed to the machine head 3, is slidably installed within the slide rail 72. A screw 73, rotatably connected to the slide rail 72, is threaded onto the moving block 75. A motor 74 is installed on the knitting machine body 1 to drive the screw 73 to rotate. When the motor 74 is started, the screw 73 rotates, causing the moving block 75 to move back and forth along the slide rail 72, thereby causing the machine head 3 to move back and forth.

[0037] Example 2

[0038] refer to Figure 6 The method is basically the same as in Embodiment 1, but with an improvement in that the power component is an electromagnet 89 used in conjunction with the iron block 88. When the machine head 3 moves to the appropriate position, the electromagnet 89 works, the iron block 88 is attracted and moved upward, and the corresponding pop-out block can disengage from the swing rod 61. During this process, the spring 84 is stretched. When the electromagnet 89 is turned off, the pop-out block will move down to its original position due to the tension of the spring 84.

[0039] Example 3

[0040] refer to Figure 9 Similar to Embodiment 1, but with an optimization, the power component can be configured as follows: the power component includes a hydraulic rod 89a installed inside the cavity 81, and a hanging rod 89b that cooperates with the iron block 88 is fixed to the movable end of the hydraulic rod 89a. When the machine head 3 moves to a suitable position, the hydraulic rod 89a operates, driving the hanging rod 89b upwards, causing the iron block 88 to move upwards as well, and the corresponding pop-out block can then disengage from the swing rod 61.

[0041] Example 4

[0042] Similar to Embodiment 1, but with an improvement, multiple sets of slide rail 4, wire feeding mechanism 5, clamping mechanism 6 and ejection mechanism 8 are provided.

[0043] All components used in this application are standard parts that can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets and welding that are mature in the existing technology. The machinery, parts and electrical equipment all adopt conventional models in the existing technology.

[0044] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of the present invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of the present invention, they are all within the protection scope of the present invention.
