Description

Technical Field

[0001] This utility model belongs to the field of textile equipment technology, and in particular relates to a pressing and unloading drive component and pressing and unloading mechanism for a flipping semi-ring mechanism. Background Technology

[0002] In textile machinery, the reversing semi-ring mechanism is a key component for achieving complex weaving and high-efficiency loop formation. One of its core functions is to control the unwinding rings on the fixed and reversing sides through the unwinding drive assembly, thereby completing precise unwinding actions.

[0003] In existing technologies, most methods involve rigid connections via keyways or similar structures, or directly fixing the unwinding loop to the axial drive assembly. This results in the circumferential rotation of the ring base being locked due to the circumferential constraint between the two when the axial drive assembly pushes the unwinding loop for axial unwinding. If the ring base needs to rotate, the unwinding drive must first be released, severely limiting the dynamic performance and weaving efficiency of the equipment.

[0004] Therefore, there is an urgent need in this field for a novel pressing and unloading drive assembly that can solve the motion interference problem between axial unloading drive and circumferential rotation of the annular base. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a more flexible reversing semi-ring mechanism for driving the depressing line.

[0006] Another objective of this invention is to address the aforementioned problems by providing a pressing and unloading mechanism for a flipping semi-ring mechanism.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: The retracting drive assembly of the flipping semi-ring mechanism includes a first push rod unit disposed on an annular base and capable of being connected to the fixed-side retracting ring. The annular base is also provided with a second push rod unit capable of axially moving the flipping-side retracting ring outward. The first push rod unit and the second push rod unit are connected to the retracting upper ring. A circumferential sliding mechanism is provided between the retracting upper ring and the annular base. When the retracting upper ring is subjected to the axial thrust of the retracting upper ring axial displacement drive assembly, the circumferential sliding mechanism allows the annular base to independently rotate circumferentially under the drive of external force.

[0008] By incorporating a circumferential sliding mechanism between the unwinding loop and its axial drive assembly, the axial movement of the unwinding loop is separated from the circumferential rotation of the annular base. The unwinding loop's axial drive assembly pushes the unwinding loop axially, which in turn pushes the first and second push rods to perform the unwinding action. Simultaneously, the annular base can rotate freely and unaffected circumferentially to adjust the weaving position. This achieves parallel execution of the two actions, resulting in shorter cycle times and improved production efficiency.

[0009] In the aforementioned retractable semi-ring mechanism's thread-unwinding drive assembly, the circumferential sliding mechanism includes an annular blind groove on the upper end of the annular base for sliding guidance. The thread-unwinding upper ring is disposed within the annular blind groove and is capable of axial movement. A thread-unwinding upper sliding ring is provided at the outer end of the thread-unwinding upper ring. A resistance-reducing structure is provided between the thread-unwinding upper sliding ring and the thread-unwinding upper ring. An axial anti-disengagement structure is provided between the thread-unwinding upper ring and the outer end of the annular blind groove. The groove wall of the annular blind groove forms a guide surface for the thread-unwinding upper ring, ensuring that the thread-unwinding upper ring will not skew or jam, thus guaranteeing the linear accuracy of the thread-unwinding action. The resistance-reducing structure makes the relative circumferential rotation between the thread-unwinding upper sliding ring and the thread-unwinding upper ring smoother.

[0010] In the aforementioned retractable semi-ring mechanism's press-and-release drive assembly, the drag-reducing structure includes a bearing disposed between the release slip ring and the release upper ring. The bearing fulfills its core function of allowing low-resistance circumferential rotation while bearing axial loads. It efficiently transmits the axial thrust applied by the release upper ring shaft displacement drive assembly to the release upper ring via the release slip ring.

[0011] In the aforementioned retractable semi-ring mechanism's retraction drive assembly, the axial anti-detachment structure includes an inner step disposed on the inner and / or outer side of the outer end of the slip ring on the retraction line, and a retaining edge at the outer end of the annular blind groove that can engage with the inner step. The inner step and the retaining edge form a mechanical interlocking structure, which can prevent the slip ring on the retraction line from axially disengaging from the annular blind groove, offering advantages of high efficiency, reliability, and greater stability.

[0012] In the aforementioned reversing semi-ring mechanism's pressing and unloading drive assembly, the annular base includes an outer base body and an inner cylinder body, with the annular blind groove formed between the upper end of the outer base body and the upper end of the inner cylinder body. The modular design enhances assembly convenience and facilitates processing, thus reducing production costs.

[0013] In the aforementioned reversing semi-ring mechanism's pressing line drive assembly, the outer seat and inner cylinder are detachably connected. This detachable design allows maintenance personnel to quickly replace or maintain the internal parts by simply removing the inner cylinder on-site after long-term operation. This reduces equipment downtime and lowers maintenance costs for users.

[0014] In the aforementioned reversing semi-ring mechanism's press-out line drive assembly, the lower end of the inner cylinder is threaded to the inner thread step of the outer seat's inner bore via an external thread. The threaded connection provides strong tensile, torsional, and radial positioning capabilities. During the rotation and start-stop of the annular base, the assembly is subjected to torque; the threaded connection effectively transmits this torque while preventing additional relative rotation.

[0015] In the aforementioned reversing semi-ring mechanism's pressing and unloading drive assembly, the first push rod unit includes multiple first push rods, and at least one first push rod is provided with a first elastic reset member between itself and the annular base. The second pusher unit includes multiple second pushers, with at least one second pusher having a second elastic reset element between it and the annular base. The elastic reset element ensures that the entire transmission chain remains tightly fitted, eliminating backlash and guaranteeing consistent starting points for each unwinding action, thereby improving weaving precision and product quality.

[0016] The thread-pressing and unloading mechanism of this flipping semi-ring mechanism includes an annular base. The annular base is provided with a thread-pressing and unloading drive assembly of the flipping semi-ring mechanism as described above. The lower end of the annular base is provided with a fixed semi-ring seat and a flipping semi-ring seat. The flipping semi-ring seat can be flipped relative to the fixed semi-ring seat. The lower ends of the fixed semi-ring seat and the flipping semi-ring seat are respectively provided with a fixed side needle seat and a flipping side needle seat. The lower ends of the fixed side needle seat and the flipping side needle seat are respectively provided with a fixed side thread-unloading ring and a flipping side thread-unloading ring. An elastic reset unit is provided between the flipping semi-ring seat and the flipping side needle seat.

[0017] By integrating the entire mechanism into a ring-shaped base and mounting it with the inner cylinder as the central axis, a highly rigid whole is formed. This ensures the relative positional accuracy between the fixed side and the flipping side, and between the needle and the unwinding ring, under high-speed rotation and frequent start-stop operations, thus improving the quality of the produced textiles.

[0018] In the aforementioned retractable semi-ring mechanism, the elastic reset unit includes a retractable side reset spring disposed between the retractable semi-ring seat and the retractable side retractable ring. The retractable side reset spring is threaded through a retractable side reset spring bolt. This threaded spring bolt solves the problem of buckling instability when the spring is compressed, ensuring the reliability of the reset action.

[0019] In the above-mentioned retracting mechanism of the flipping semi-ring mechanism, an upper ring base is provided with a retracting upper ring shaft shifting drive assembly located on the upper side of the frame flipping seam station. The bottom of the retracting upper ring shaft shifting drive assembly is provided with a plurality of retracting cylinders distributed along the circumference of the retracting upper ring.

[0020] Compared with existing technologies, the advantages of this flipping semi-ring mechanism's thread-unwinding drive assembly and thread-unwinding mechanism are: 1. The thread-unwinding action and the rotation of the ring base can be synchronized, improving weaving efficiency and production speed. 2. It features a resistance-reducing design, lowering drive energy consumption and reducing wear, resulting in a longer service life and higher reliability of the equipment. 3. It has an elastic reset structure design, ensuring high positional accuracy and more stable and reliable equipment operation. Attached Figure Description

Detailed Implementation

[0026] like Figures 1 to 4 As shown, the retracting drive assembly of this flipping semi-ring mechanism includes a first push rod unit 11 that can be connected to the fixed-side retracting ring 2 and is mounted on an annular base 1. The annular base 1 is also provided with a second push rod unit 12 that can be used to move the flipping-side retracting ring 3 axially outward. The first push rod unit 11 and the second push rod unit 12 are connected to the retracting upper ring 4. A circumferential sliding mechanism 42 is provided between the retracting upper ring 4 and the annular base 1. When the retracting upper ring 4 is subjected to the axial thrust of the retracting upper ring shaft displacement drive assembly 41, the circumferential sliding mechanism 42 allows the annular base 1 to rotate circumferentially independently under the drive of external force.

[0027] The annular base 1 is also provided with four second push rods 121 that can be used to rotate the side retraction ring 3 outward axially. The first push rod 111 and the second push rod 121 are connected to the retraction ring 4. A circumferential sliding mechanism 42 is provided between the retraction ring 4 and the retraction ring shaft displacement drive assembly 41, which can rotate the annular base 1 circumferentially under the action of external force when the axial thrust of the retraction ring shaft displacement drive assembly 41 is applied to the retraction ring 4.

[0028] In this embodiment, by using the circumferential sliding mechanism 42 disposed between the retraction ring 4 and the retraction ring shaft displacement drive assembly 41, the annular base 1 can still rotate without interference under external drive when the axial thrust of the retraction ring shaft displacement drive assembly 41 acts on the retraction ring 4 to drive the first push rod 111 and the second push rod 121 to perform the retraction action. This achieves parallel axial retraction motion and circumferential rotation motion of the base, resulting in more flexible drive and improved equipment efficiency.

[0029] More specifically, the circumferential sliding mechanism 42 includes an annular blind groove 421 disposed on the upper end of the annular base 1 for sliding guidance, an upper retractable ring 4 disposed in the annular blind groove 421 and capable of axial movement, an upper retractable sliding ring 431 disposed at the outer end of the upper retractable ring 4, a resistance-reducing structure 43 disposed between the upper retractable sliding ring 431 and the upper retractable ring 4, and an axial anti-detachment structure 432 disposed between the upper retractable ring 4 and the outer end of the annular blind groove 421.

[0030] like Figure 2 As shown, the drag-reducing structure 43 includes a bearing 433 disposed between the slip ring 431 and the slip ring 4 on the upper slip line.

[0031] More specifically, the axial anti-detachment structure 432 includes an inner step 434 disposed on the inner side of the outer end of the slip ring 431 on the retraction line, and a retaining edge 435 disposed at the outer end of the annular blind groove 421 that can cooperate with the inner step 434.

[0032] More specifically, the annular base 1 includes an outer base body 13 and an inner cylinder body 14, with an annular blind groove 421 formed between the upper end of the outer base body 13 and the upper end of the inner cylinder body 14.

[0033] In this embodiment, the circumferential sliding mechanism 42 includes a pulley 132 and a bearing ring 133 on the outer wall of the outer seat 13. The pulley 132 is used to connect to the transmission belt to obtain the power for circumferential rotation. The bearing ring 133 is provided with balls inside to reduce resistance. The bearing ring 133 is located below the pulley 132.

[0034] In this embodiment, the retaining edge 435 is located on the outer side of the top of the inner cylinder 14, abutting against the inner step 434 of the slip ring 431 on the retraction line.

[0035] like Figure 2 As shown, the outer base 13 and the inner cylinder 14 are detachably connected. The lower end of the inner cylinder 14 is screwed to the internal thread step 131 of the inner hole of the outer base 13 via an external thread.

[0036] More specifically, the first push rod unit 11 includes multiple first push rods 111, and at least one first push rod 111 is provided with a first elastic reset member 112 between itself and the annular base 1; The second push rod unit 12 includes multiple second push rods 121, and at least one second push rod 121 is provided with a second elastic reset member 122 between it and the annular base 1.

[0037] In this embodiment, the second elastic reset member 122 is a retractable elastic buffer column with a hemispherical top, and is disposed at a corresponding position below the second push rod 121. The first elastic reset member 112 and the second elastic reset member 122 are coaxially arranged with the first push rod 111 and the second push rod 121, respectively, to realize the upward reset of the first push rod unit 11 and the second push rod unit 12.

[0038] like Figures 1 to 4 As shown, the pressing and unloading mechanism of this flipping half-ring mechanism includes an annular base 1. The annular base 1 is provided with a pressing and unloading drive assembly of the flipping half-ring mechanism as described above. The lower end of the annular base 1 is provided with a fixed half-ring seat 21 and a flipping half-ring seat 31. The flipping half-ring seat 31 can be flipped relative to the fixed half-ring seat 21. The lower end of the fixed half-ring seat 21 and the lower end of the flipping half-ring seat 31 are respectively provided with a fixed side needle seat 22 and a flipping side needle seat 32. The lower ends of the fixed side needle seat 22 and the flipping side needle seat 32 are respectively provided with a fixed side unloading ring 2 and a flipping side unloading ring 3. An elastic reset unit 33 is provided between the flipping half-ring seat 31 and the flipping side needle seat 32.

[0039] By linking the first push rod 111 with the fixed-side unwinding ring 2 and the second push rod 121 with the flip-side unwinding ring 3, and by setting an elastic reset unit 33 to connect the flip-side half-ring seat 31 and the flip-side needle seat 32, the fixed side and the flip side can independently or synchronously complete the precise unwinding action during the circumferential rotation of the annular base 1, and ensure that the flip side can automatically and reliably reset after the action, thereby achieving the effect of high-efficiency, high-precision compound motion and stable and reliable operation.

[0040] More specifically, the elastic reset unit 33 includes a flip-side reset spring 331 disposed between the flip-side semi-ring seat 31 and the flip-side unwinding ring 3, and the flip-side reset spring 331 is mounted on the flip-side reset spring bolt 332.

[0041] In this embodiment, the flip-side reset spring 331 is installed inside the elastic reset unit 33, and the installation position of the flip-side reset spring 331 is in the prior art.

[0042] like Figure 1 As shown, an upper ring base 1 is provided with a retraction upper ring shaft shift drive assembly 41 located on the upper side of the frame flipping seam station. The bottom of the retraction upper ring shaft shift drive assembly 41 is provided with a plurality of retraction cylinders 411 distributed upward along the circumference of the retraction upper ring 4.

[0043] In this embodiment, the unwinding upper ring shaft shift drive assembly 41 includes four unwinding cylinders 411. The unwinding cylinders 411 are fixed above the flip-joint seam station of the machine frame. When the flip-joint half-ring assembly swings to the flip-joint seam station, the piston rod output end of the unwinding cylinder 411 can extend downward to push the unwinding upper ring 4. The unwinding cylinders 411 are evenly distributed along the annular unwinding upper ring 4.

[0044] The working principle of this embodiment is as follows: First, the unwinding cylinder 411 of the unwinding upper ring shaft drive assembly 41 operates synchronously, applying an axial thrust downward. This thrust is transmitted to the unwinding upper ring 4 through the unwinding upper slip ring 431 and the bearing 433 of the drag-reducing structure 43. During this process, the unwinding upper slip ring 431 and the unwinding upper ring 4 achieve a low-friction relative circumferential movement through the bearing 433.

[0045] Next, the unwinding ring 4 moves axially downward within the annular blind groove 421, simultaneously pushing the first push rod 111 and the second push rod 121 downward. The first push rod 111 drives the fixed-side unwinding ring 2 to move downward, while the second push rod 121 drives the flip-side unwinding ring 3 to overcome the elastic force of the flip-side reset spring 331 in the elastic reset unit 33 and move axially downward.

[0046] Meanwhile, the annular base 1 can receive external transmission power through the pulley 132 on its outer seat 13, driving the entire annular base 1 and its lower fixed semi-annular seat 21, flipping semi-annular seat 31, and other components to rotate circumferentially. Due to the presence of the circumferential sliding mechanism 42, the axial thrust of the retraction shaft drive assembly 41 and the circumferential rotation of the annular base 1 are independent of each other and do not interfere with each other, thus achieving synchronous retraction and rotation.

[0047] After the unwinding action is completed, the unwinding cylinder 411 retracts, releasing the axial thrust. At this time, the second push rod 121 and the unwinding slip ring 4 return to their upward position; simultaneously, the flip-side reset spring 331 in the elastic reset unit 33 drives the flip-side needle seat 32 and the flip-side unwinding slip ring 3 to return to their upward position. The inner step 434 of the axial anti-detachment structure 432 engages fully with the retaining edge 435 to prevent the unwinding slip ring 431 from axially disengaging from the annular blind groove 421, ensuring stable operation of the mechanism.

[0048] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0049] Although this document uses numerous terms such as annular base, first push rod unit, first push rod, first elastic reset component, second push rod unit, second push rod, second elastic reset component, outer seat body, internal thread step, pulley, bearing ring, inner cylinder, fixed side unwinding ring, fixed half-ring seat, fixed side pin seat, flipping side unwinding ring, flipping half-ring seat, flipping side pin seat, elastic reset unit, flipping side reset spring, flipping side reset spring bolt, unwinding upper ring, unwinding upper ring shaft shift drive assembly, unwinding cylinder, circumferential sliding mechanism, annular blind groove, resistance reduction structure, unwinding upper slip ring, axial anti-detachment structure, bearing, inner step, and retaining edge, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
