Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and specifically to a wire clamping assembly with elastic clamping fingers. Background Technology

[0002] The yarn clamping assembly is an important component of textile equipment. Existing yarn clamping assemblies first extend the clamps to allow the yarn to fall into the clamps and be clamped, then pull the yarn back with the clamps, and finally cut the yarn with scissors.

[0003] For example, CN219058108U discloses an anti-yarn breakage clamping assembly. The anti-yarn breakage clamping assembly is mounted on a track of a base, and the yarn is conveyed above the anti-yarn breakage clamping assembly. The anti-yarn breakage clamping assembly includes a rack, a shift plate, a clamp, a first positioning block, and a second positioning block. The rack drives the anti-yarn breakage clamping assembly to perform a linear reciprocating motion. The rack and the shift plate are connected by a spring, and the two can move relative to each other up and down. The direction of the spring force is along the movement trajectory of the anti-yarn breakage clamping assembly. The clamp is hinged to the shift plate and the rack respectively. The first positioning block is hinged to the rack. The shift plate is provided with a first groove. The cooperation between the first positioning block and the first groove is used to control the opening or closing of the clamp. The second positioning block is hinged to the clamp or the rack. The second positioning block is connected to a torsion spring. The other end of the torsion spring is connected to the upper end of the shift plate. The second positioning block is used to control whether the clamp is fully closed.

[0004] However, the existing yarn clamping components have too small a clamping range, making them incompatible with yarns of different thicknesses, and the lack of a cushioning structure makes the yarns prone to breakage. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model proposes a wire clamping assembly with elastic finger clamping.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] A wire clamping assembly with elastic clamping fingers includes a drive base, on which a sliding groove is formed, and a wire clamping structure for clamping wire is slidably disposed in the sliding groove. The wire clamping structure includes a sliding plate, a drive plate for driving the sliding plate to slide, and a clamping finger module hinged to the drive plate and the sliding plate.

[0008] The clamping finger module includes a first clamping finger, a second clamping finger, and a linkage group for driving the first and second clamping fingers to open or close. The first clamping finger forms a gap adjustment slit extending away from the clamping direction on one side for clamping the yarn, and a buffer slit extending toward the clamping direction on the other side.

[0009] Preferably, the width of the buffer gap is 0.2mm-0.4mm. Through the above improvements, the buffer gap can play a buffering role when the finger clamp module is closed, and can further prevent the yarn from being pinched and broken.

[0010] Preferably, the linkage assembly includes a first drive rod and a second drive rod. The rotating ends of the first and second gripping fingers are hinged to the drive plate. One end of the first drive rod is hinged to the first gripping finger, and the other end is hinged to the sliding plate. One end of the second drive rod is hinged to the second gripping finger, and the other end is hinged to the sliding plate. With the above improvements, in the initial stage, when the drive plate moves, the sliding plate is restricted from moving, so that the drive plate and the sliding plate move relative to each other, thereby opening the first and second gripping fingers so that the yarn can enter between the first and second gripping fingers.

[0011] Preferably, the gap adjustment seam and the buffer seam are arranged in parallel and staggered configurations, with the gap adjustment seam located near the rotating end of the first clamping finger and the buffer seam located near the clamping end of the first clamping finger. Through these improvements, the buffer seam can provide a buffering effect when the finger is closed, the gap adjustment seam can expand the clamping range, and the width of the gap adjustment seam can be set according to the yarn thickness and number of strands, allowing the entire clamping finger module to be flexibly configured. The parallel and staggered arrangement of the gap adjustment seam and the buffer seam can ensure the structural strength of the first clamping finger.

[0012] Preferably, a drive unit is provided on the drive base, and a drive gear is provided on the drive base to be driven and connected to the output end of the drive unit. The side of the drive plate forms transmission teeth that are driven and connected to the drive gear. A first elastic element is connected between the drive plate and the sliding plate. A first locking block is hinged on the drive plate, and a limiting block is provided at the end of the sliding plate. A first locking groove is provided on the sliding plate. When the finger clamping module is in the closed state, the first locking block abuts against the limiting block. When the first locking block is placed in the first locking groove, the finger clamping module is in the open state. Through the above improvements, when the drive unit drives the drive... The drive gear rotates, and the drive gear engages with the transmission gear to make the drive plate slide. During the sliding process of the drive plate, in the initial state, the second locking block is locked in the second locking groove, and when the drive plate moves, the sliding plate is restricted to the current position, thereby opening the finger clamping module. As the drive plate continues to move, the first elastic element between the drive plate and the sliding plate pulls the sliding plate to move, causing the second locking block to disengage from the second locking groove. When the second locking block disengages from the second locking groove, the first locking block is placed in the first locking groove, so that the finger clamping module continues to move in the open state, allowing the yarn to enter between the first and second finger clamps.

[0013] Preferably, a second elastic element is provided between the drive plate and the first snap-fit ​​block, so that the first snap-fit ​​block always has a tendency to rotate toward the first snap-fit ​​groove. With the above improvement, since the first snap-fit ​​block always has a tendency to rotate toward the first snap-fit ​​groove, when the first snap-fit ​​block is placed into the first snap-fit ​​groove, the finger clamp module continues to move in an open state.

[0014] Preferably, a second latching block is hinged to the drive seat, and a second latching groove is provided on the sliding plate for the second latching block to be inserted. When the second latching block is inserted into the second latching groove, the second latching groove restricts the movement of the sliding plate so that the finger clamping module slides open with the drive plate. When the second latching block disengages from the second latching groove, the first elastic element drives the sliding plate to move so that the finger clamping module moves in an open state. With the above improvements, when the second latching block disengages from the second latching groove, the sliding plate can slide together with the drive plate, and at this time the first latching block is inserted into the first latching groove, and the finger clamping module moves in an open state so that the yarn can enter between the first and second finger clamps.

[0015] Preferably, the drive seat is provided with a third elastic element, one end of which is connected to the drive seat and the other end is connected to the second locking block, so that the second locking block always has a tendency to rotate toward the sliding plate. Through the above improvement, the second locking block is placed in the second locking groove to restrict the movement of the sliding plate.

[0016] Preferably, the limiting block has an insertion protrusion, the sliding plate has a slot for inserting the insertion protrusion, and the limiting block is provided with an adjusting screw. The adjusting screw rotates to move the limiting block away from or closer to the sliding plate. Through the above improvements, the adjusting screw can be rotated to change the distance between the limiting block and the sliding plate, thereby changing the spacing of the finger clamping module to accommodate different yarns.

[0017] Preferably, the limiting block is provided with a buffer pad. Through the above improvements, the impact force of the collision with the first locking block 104 is reduced, and a buffering effect is played, thereby preventing the wire from being snapped.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] By setting a sliding groove on the drive seat and sliding a wire clamping structure within the sliding groove, the wire clamping structure includes a sliding plate, a drive plate that drives the sliding plate to slide, and a finger clamping module hinged to the drive plate and the sliding plate. The finger clamping module includes a first finger clamping, a second finger clamping, and a linkage group that drives the first and second fingers clamping to open or close. The first finger clamping is used to clamp the yarn and has a gap adjustment slit on one side and a buffer slit on the other side. Compared with the existing wire clamping structure, the entire finger clamping module is flexibly set. The buffer slit can play a buffering role when closing, so as to reduce the risk of cutting the yarn. Furthermore, the gap adjustment slit is used to expand the clamping range to match yarns of different thicknesses. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0030] like Figure 1-7 As shown, a wire clamping assembly with elastic finger clamping includes a drive base 1, a sliding groove 2 formed on the drive base 1, and a wire clamping structure 3 for clamping wire slidably disposed in the sliding groove 2. The wire clamping structure 3 includes a sliding plate 1.1, a drive plate 1.2 that drives the sliding plate 1.1 to slide, and a finger clamping module 1.3 hinged to the drive plate 1.2 and the sliding plate 1.1.

[0031] Specifically, the finger clamping module 1.3 includes a first finger clamping 2.1, a second finger clamping 2.2, and a linkage group 2.3 for driving the first finger clamping 2.1 and the second finger clamping 2.2 to open or close. The first finger clamping 2.1 has a gap adjustment slit 2.4 extending away from the clamping direction on one side and a buffer slit 2.5 extending towards the clamping direction on the other side, so that the entire finger clamping module 1.3 is elastically set. The buffer slit 2.5 can play a buffering role when closing to reduce the risk of cutting the yarn, and the gap adjustment slit 2.4 is used to expand the clamping range to match yarns of different thicknesses.

[0032] Preferably, the width of the buffer gap 2.5 is 0.2mm-0.4mm. In this application, the width of the buffer gap 2.5 is 0.3mm. The buffer gap 2.5 can buffer the closing of the finger clamping module 1.3, thereby further preventing the yarn from being broken. The width of the gap 2.4 can be adjusted according to the yarn thickness and the number of strands to achieve better yarn clamping.

[0033] Of course, in daily implementation, the gap adjustment joint 2.4 and the buffer joint 2.5 can be set on the first clamping finger 2.1 or the second clamping finger 2.2. At the same time, the gap adjustment joint 2.4 and the buffer joint 2.5 can also be set on both the first clamping finger 2.1 and the second clamping finger 2.2 as needed to match the usage scenario.

[0034] In addition, the gap adjustment slot 2.4 and the buffer slot 2.5 are arranged in parallel and staggered, with the gap adjustment slot 2.4 located near the rotating end of the first finger 2.1 and the buffer slot 2.5 located near the clamping end of the first finger 2.1. They work together to enhance the elasticity of the finger clamping module 1.3. The staggered arrangement of the gap adjustment slot 2.4 and the buffer slot 2.5 ensures the structural strength of the first finger 2.1.

[0035] like Figure 1-5 As shown, in a further explanation of the embodiment of the clamping structure 3, a driving unit 3.3 is provided on the driving base 1, and a driving gear 3.4 is provided on the driving base 1 and is connected to the output end of the driving unit 3.3. The side of the driving plate 1.2 forms a transmission tooth 3.5 that is connected to the driving gear 3.4. A first elastic element 3.6 is connected between the driving plate 1.2 and the sliding plate 1.1. A first locking block 3.7 is hinged on the driving plate 1.2, and a limiting block 3.8 is provided at the end of the sliding plate 1.1. A first locking groove 3.9 is provided on the sliding plate 1.1. When the finger clamping module 1.3 is in the closed state, the first locking block 3.7 abuts against the limiting block 3.8. When the first locking block 3.7 is placed in the first locking groove 3.9, the finger clamping module 1.3 is in the open state.

[0036] Furthermore, a second latching block 4.2 is hinged to the drive base 1, and a second latching groove 4.3 is provided on the sliding plate 1.1 for the second latching block 4.2 to be inserted. When the second latching block 4.2 is inserted into the second latching groove 4.3, the second latching groove 4.3 restricts the movement of the sliding plate 1.1 so that the finger clamping module 1.3 slides open with the drive plate 1.2. When the second latching block 4.2 disengages from the second latching groove 4.3, the first elastic element 3.6 drives the sliding plate 1.1 to move so that the finger clamping module 1.3 moves in an open state.

[0037] During the movement of the finger clamping module 1.3, in the initial state, the first locking block 3.7 abuts against the limiting block 3.8, at which time the finger clamping module 1.3 is in a closed state, and at the same time, the second locking block 4.2 is engaged in the second locking groove 4.3. The drive unit 3.3 drives the drive gear 3.4 to rotate through the transmission gear 3.5 wheel set. The drive gear 3.4 cooperates with the transmission gear 3.5 to make the drive plate 1.2 slide, and the sliding plate 1.1 is restricted to the current position, thereby making the finger clamping module 1. 3. As the drive plate 1.2 continues to move, the first elastic element 3.6 between the drive plate 1.2 and the sliding plate 1.1 pulls the sliding plate 1.1 to move, causing the second locking block 4.2 to disengage from the second locking groove 4.3. When the second locking block 4.2 disengages from the second locking groove 4.3, the first locking block 3.7 is placed into the first locking groove 3.9, causing the finger clamping module 1.3 to continue moving in an open state, allowing the yarn to enter between the first finger clamp 2.1 and the second finger clamp 2.2 to achieve yarn feeding.

[0038] After the yarn feed is completed, as the drive plate 1.2 and the sliding plate 1.1 continue to move, the protrusion extending to the side of the first snap-fit ​​block 3.7 will abut against the drive seat 1, causing the first snap-fit ​​block 3.7 to disengage from the first snap-fit ​​groove 3.9 and abut against the limiting block 3.8, so that the first clamping finger 2.1 and the second clamping finger 2.2 clamp the yarn.

[0039] Furthermore, a second elastic element 4.1 is provided between the drive plate 1.2 and the first latching block 3.7 so that the first latching block 3.7 always has a tendency to rotate toward the first latching groove 3.9. Since the first latching block 3.7 always has a tendency to rotate toward the first latching groove 3.9, when the first latching block 3.7 is placed into the first latching groove 3.9, the finger clamping module 1.3 is in an open state.

[0040] In addition, a third elastic element 4.4 is provided on the drive seat 1. One end of the third elastic element 4.4 is connected to the drive seat 1, and the other end is connected to the second locking block 4.2, so that the second locking block 4.2 always has a tendency to rotate toward the sliding plate 1.1, so that the second locking block 4.2 is placed in the second locking groove 4.3 to restrict the movement of the sliding plate 1.1.

[0041] like Figure 1-5 As shown, as a further explanation of the embodiment of the finger clamping module 1.3, the linkage group 2.3 includes a first drive rod 3.1 and a second drive rod 3.2. The rotating ends of the first finger clamping 2.1 and the second finger clamping 2.2 are hinged to the drive plate 1.2. One end of the first drive rod is hinged to the first finger clamping 2.1 and the other end is hinged to the sliding plate 1.1. One end of the second drive rod is hinged to the second finger clamping 2.2 and the other end is hinged to the sliding plate 1.1. In the initial stage, when the drive plate 1.2 moves, the second locking block 4.2 is placed into the second locking groove 4.3, and the sliding plate 1.1 is restricted from moving, so that the drive plate 1.2 and the sliding plate 1.1 move relative to each other, thereby opening the first finger clamping 2.1 and the second finger clamping 2.2 so that the yarn can enter between the first finger clamping 2.1 and the second finger clamping 2.2.

[0042] like Figure 5-7 As shown, in some other embodiments, the limiting block 3.8 has an insertion protrusion 5.1, the sliding plate 1.1 has a slot 5.2 for the insertion protrusion 5.1 to be inserted, and the limiting block 3.8 is provided with an adjusting screw 5.3. The adjusting screw 5.3 is rotated to move the limiting block 3.8 away from or closer to the sliding plate 1.1. The adjusting screw can be rotated to change the distance between the limiting block 3.8 and the sliding plate 1.1, thereby changing the spacing of the finger clamping module 1.3 to accommodate different yarns.

[0043] Preferably, the limiting block 3.8 is provided with a buffer pad 5.4 to reduce the impact force when it hits the first locking block 3.7 and to play a buffering role, thereby preventing the wire from being pinched and broken.

[0044] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
