[0001] The invention relates to the technical field of textile equipment, in particular to a threading needle linked thread breaking actuator and a mesh cloth pre-seam pretreatment device with the actuator. Background Art

[0002] In the production process of the textile industry, the seaming link is crucial. Before the seaming operation, some warp threads need to be cut off to expose the thread ends, and then joined with new threads. This step directly affects the quality of the subsequent fabric and the effect of the finished product.

[0003] With the advancement of textile technology, the use of automated equipment is becoming increasingly widespread, creating new opportunities for improving production efficiency and quality. However, while some advanced textile machinery is equipped with auxiliary devices such as automatic threading and warp tying, which has increased the degree of automation in the production process, the pre-processing process of obtaining the spliced ​​threads before tying still relies heavily on manual labor.

[0067] A preferred embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0068] participate Figures 1 to 10The mesh pre-seaming pretreatment device provided by the present invention can efficiently and automatically complete the cutting of the warp threads on the mesh and the collection of thread ends through the coordinated work of various components. The pretreatment device includes a workbench 7 and an actuator 1, a thread end collecting mechanism 2, a translation mechanism 3 and a pressing mechanism 4 installed on one side of the workbench 7. The actuator 1 is used to implement the cutting operation of the warp threads of the mesh, that is, the warp cutting operation. The thread end collecting mechanism 2 is arranged below the actuator 1, and is used to collect the thread ends cut off and dropped by the actuator 1, that is, the dust collection operation. The translation mechanism 3 is used to drive the actuator 1 to move within the set stroke. The pressing mechanism 4 ensures that the mesh will not move or deform when the actuator 1 performs the warp cutting operation.

[0069] See Figures 2 to 6 , the threading needle linkage breaking actuator is used to cut the warp of the mesh in an orderly manner. Figure 2 For reference purposes, the left, right, front, and rear directions in the diagram are defined for explanation.

[0070] The actuator 1 includes a base film 11, a threading needle 12, a thread cutter 13, a linkage assembly 14 and a first drive motor 15. The base film 11 is made of a rigid material and is arranged horizontally to provide stable support for the mesh to be processed. A threading hole 111 is vertically arranged on the left side of the base film 11. The threading needle 12 is coaxial with the threading hole 111 and is arranged below the base film 11. The threading needle 12 is provided with a hooking portion 121 on the outer peripheral wall near its needle tip. The threading needle 12 is configured to be able to pass through the threading hole 111 in a vertical direction and be inserted between the two warps of the mesh, with the hooking portion 121 being placed above one of the warps. The thread cutter 13 is slidably fitted to the bottom of the base film 11 in a horizontal direction, and the blade of the thread cutter 13 is arranged near the right side of the threading hole 111.

[0071] The threading needle 12 and the thread cutter 13 are tightly linked with each other by means of a linkage assembly 14, and the first drive motor 15 serves as a power source, providing the driving force required for the operation of the linkage assembly 14. When the first drive motor 15 is started, the linkage assembly 14 drives the threading needle 12 to extend upward through the needle hole 111, and the thread cutter 13 simultaneously moves to the right to avoid it, leaving enough space for the threading needle to extend and ensure smooth operation. Subsequently, when the linkage assembly 14 drives the threading needle 12 to retract downward, its upper thread hooking portion 121 will hook a warp thread and bring the warp thread to the front side of the blade of the thread cutter 13 during the continuous descent process. The thread cutter 13 then moves to the left synchronously to cut the target wire harness.

[0072] Note: In the fabric structure of a mesh, the warp threads are arranged in an orderly fashion along the length (i.e., longitudinal) of the fabric. During the weaving process, the warp threads are the first to be attached to the loom. When the mesh needs to be spliced ​​to extend its length, the key to this operation lies in splicing the warp threads—connecting the new warp threads to the existing warp threads of the mesh. The regular arrangement of the warp threads within the mesh facilitates precise thread cutting. During the warp breaking process, the movement of the threading needle is aligned with the spacing between the warp threads. This ensures that each movement of the threading needle precisely hooks onto a warp thread, ensuring accurate thread breaking.

[0073] In order to further achieve efficient warp cutting, the threading needle and the thread cutting knife are connected through a linkage component so that the movement rhythm of the two components during operation is highly consistent. Through linkage operation, the operating efficiency of the entire device is improved, the operation process is smoother and more efficient, and failures caused by uncoordinated movements are effectively avoided, ensuring stable, reliable and efficient operation of the device.

[0074] The linkage assembly 14 is mounted on the support base 16 and includes a movement module 141 for driving the threading needle 12 to move back and forth, and a connecting rod module 142, which is connected to the movement module 141 to drive the thread cutter 13 to move back and forth. The specific power transmission process is as follows: the first drive motor 15 drives the movement module 141, which in turn drives the movement of the connecting rod module 142, thereby achieving the coordinated operation of the threading needle 12 and the thread cutter 13.

[0075] The movable module 141 comprises a guide rail 1411 vertically mounted on the support base 16, a transmission base 1412 slidably mounted on the guide rail 1411 via a slider, a connecting shaft 1413 horizontally mounted at the bottom of the transmission base 1412 in the front-to-back direction, with the front end extending into a transmission cavity 14121, and a crank 1414 vertically mounted within the transmission cavity 14121. The threading needle 12 is mounted at the top of the transmission base 1412, and the transmission cavity 14121 is located on the side of the transmission base 1412 facing the first drive motor. A cam 1415 is mounted on the output shaft of the first drive motor, and the upper and lower ends of the crank 1414 are rotatably connected to the connecting shaft 1413 and the cam 1415, respectively.

[0076] When the first drive motor is started, the power outputted by the first drive motor drives the cam 1415 to start rotating. The rotation of the cam 1415 drives the crank to drive the transmission seat to move up and down, thereby realizing the operation of extending or retracting the threading needle from the film.

[0077] Among them, the connecting rod module 142 is provided on the support seat 16 and arranged on the right side of the moving module 141, and is used to convert the vertical power output by the moving module 141 into horizontal power, thereby realizing the coordinated movement of the wire cutting knife and the threading needle in two directions perpendicular to each other.

[0078] Specifically, the connecting rod module 142 includes a connecting rod 1421, a crank arm 1422, a supporting rocker arm 1423, an adjusting arm 1424 and a push-pull rod 1425; one end of the connecting rod 1421 is tilted from bottom to top and passes through the side wall of the transmission seat 1412 and is rotatably connected to the connecting shaft 1413 to transmit the power of the first drive motor to the connecting rod module 142 through the transmission seat.

[0079] The connecting rod 1421 tilts upward from the bottom and passes through the side wall of the transmission base 1412 to be rotatably connected to the connecting shaft 1413. The crank arm 1422 has a V-shaped structure and is arranged on the right side of the connecting rod 1421. It has a pulled portion 14221, a swinging portion 14222, and a connecting portion 14223 connecting the two to form a fulcrum. The connecting portion 14223 is rotatably connected to the support base 16 and serves as the rotational fulcrum of the crank arm. The pulled portion 14221 is arc-shaped, with its end being rotatably connected to the connecting rod 1421. The swinging portion 14222 is vertically arranged, with its end being rotatably connected to the adjustment arm 1424. The V-shaped structural design of the crank arm allows the pulled portion 14221 to swing up and down under the action of the connecting rod 1421. The rotation characteristics of the connecting portion 14223 can convert this vertical swing into a left and right swing of the swinging portion 14222, thereby achieving a change in motion direction and providing support for the subsequent horizontal reciprocating movement of the wire cutter.

[0080] The support rocker 1423 straddles the pulled portion 14221 of the crank arm 1422. Its lower end is pivotally connected to the support base 16, and its upper end is pivotally connected to the adjustment arm 1424. This not only serves as a connection but also provides necessary support for the adjustment arm. A relief notch 14231 is defined in the support rocker 1423 to allow the pulled portion 14221 of the crank arm 1422 to swing up and down within it, thereby ensuring coordinated and efficient movement of the entire linkage module 142.

[0081] The right end of push-pull rod 1425 is pivotally connected to adjustment arm 1424 via a pair of lugs 14241 on the right top surface of adjustment arm 1424. Push-pull rod 1425 is connected to lugs 14241 via a shaft. The left end of push-pull rod 1425 extends to the bottom of film 11 and is pivotally connected to wire cutter 13. The bottom surface of push-pull rod 1425 is designed as a slope 14251 that slopes upward from right to left. This not only ensures effective support from adjustment arm 1424 during movement, but also ensures that wire cutter 13 remains firmly attached to film 11 as the push-pull rod drives wire cutter 13 left and right. This maintains a stable cutting position for the blade of wire cutter 13, ensuring precise and efficient wire cutting.

[0082] The actuator 1 further includes a support housing 17 mounted on a support base 16, with a hinged pressure plate 18 formed on the support housing 17 to form a receiving chamber 19. The threading needle 12, the wire cutter 13, and the movable module 141 are positioned within the receiving chamber 19, achieving a high degree of integration and modularity for the actuator. This modular design not only facilitates assembly and disassembly of the actuator, reducing maintenance costs, but also enhances its ability to be used in conjunction with other extension mechanisms, thereby increasing the applicability and flexibility of the entire mechanism. Furthermore, the retractable pressure plate provides a convenient way for users to replace the threading needle 12 and the wire cutter 13, further enhancing the practicality of the actuator.

[0083] The bottom plate 11 is mounted on the pressure plate 18, and a guide groove 112 is provided on its bottom surface. The wire cutter 13 is slidably connected to the guide groove 112 and rotatably connected to the push-pull rod 1425 to ensure precise horizontal movement of the wire cutter. This ensures that the wire cutter 13, driven by the push-pull rod 1425, can slide smoothly along the guide groove 112 while maintaining flexibility with the push-pull rod 1425, achieving efficient and stable wire cutting operation.

[0084] See Figure 2 、 Figure 6 and Figure 7 A dust outlet 161 is provided on the support seat 16, and the dust outlet 161 is arranged directly below the bottom film 11 and communicates with the accommodating cavity 19; the thread end collecting mechanism 2 is provided at the dust outlet 161, which is used to collect thread end debris generated during the thread breaking or threading process to prevent it from accumulating inside the actuator and affecting the normal operation of the equipment.

[0085] Specifically, the lint collection mechanism 2 comprises a guide 21 connected to the dust outlet 161 for guiding the movement of lint, and a pneumatic conveyor 22 connected to the guide 21 via a cloth bag (not shown). The cloth bag has excellent ductility and flexibility, adapting to the dynamic changes of the actuator 1 during left and right movement, ensuring a stable connection between the guide 21 and the pneumatic conveyor 22. The pneumatic conveyor 22 generates a strong suction force, sucking the lint from the accommodating chamber 19 and conveying it to a designated collection container (not shown). This ensures efficient and stable collection of lint, preventing accumulation on the actuator and ensuring its normal operation.

[0086] See Figure 2 and Figure 7 The translation mechanism 3 is used to drive the left and right movement of the actuator to meet the warp cutting requirements of different mesh widths. Specifically, the translation mechanism 3 is positioned below the support base 16 via a bracket 5. It includes a mounting plate 31 that is parallel to the support base 16 and fixed to the bracket 5. The mounting plate 31 has a clearance hole 311 to provide space for the movement of the guide member 21 in the lint collection mechanism 2, thereby ensuring that the translation mechanism 3 and the lint collection mechanism 2 interact with each other.

[0087] In addition, the mounting plate 31 and the support base 16 are movably connected via a slider module. The slider module is generally composed of a guide rail and a slider to achieve relative movement. A drive gear 33 is provided on the output shaft of the second drive motor 34, and the drive gear 33 is tightly engaged with a passive rack 32 arranged on the bottom surface of the support base 16 in the left and right directions. When the second drive motor 34 is started, the drive gear 33 rotates so that the passive rack 32 drives the support base 16 to move left and right stably within the area corresponding to the preset stroke. This transmission mechanism has the advantages of high transmission efficiency, accurate positioning, and smooth operation.

[0088] See Figures 6 and 7 The pressing mechanism 4 is arranged above the actuator 1 and is used to press the mesh to be processed flatly onto the working area of ​​the actuator to ensure the smooth progress of the subsequent processing process.

[0089] Specifically, the pressing mechanism 4 includes two support plates 41 arranged on the front and rear sides of the pressing plate 18, a pressing plate 42 movably connected to the support plates 41, and a rotating arm 43 rotatably connected to the support plates; the pressing plate 42 is arranged at the front end of the rotating arm 43, and an armrest is provided on the rotating arm 43. The operator drives the pressing plate 42 to move by pressing the rotating arm 43 so that the two sides of its bottom are overlapped on the two support plates 41 and pressed on the pressing plate 18 to keep the mesh flat; or lift the armrest of the rotating arm to make the pressing plate 42 leave the pressing plate to loosen the mesh.

[0090] Among them, there are two rotating arms 43, including a main rotating arm 431 for receiving external force, and a driven arm 432 connected to the main rotating arm 431 through a hinge shaft 44. The main rotating arm 431 and the driven arm 432 are respectively connected to the two ends of the hinge shaft 44; the setting of the two arms ensures the stability and consistency of the pressing plate 42 during the movement.

[0091] The pressing plate 42 is movably connected to the free ends of the main rotating arm 431 and the driven arm 432 via two connecting seats 45. Its bottom surface is provided with a clearance groove 421 corresponding to the area of ​​the preset stroke, which is used to avoid the threading needle 12 of the actuator. The clearance groove 421 allows the threading needle 12 to move freely during operation without being interfered with by the pressing plate 42. At the same time, the setting of the pressing plate 42 can effectively fix other areas of the mesh to be processed, thereby ensuring the flatness of the mesh during the operation of the actuator.

[0092] A support block 46 is mounted on one of the rear support plates 41, serving as a positioning element for the rotating arm and ensuring the entire structure maintains a high degree of stability when subjected to stress. A vertically defined active cavity 461 is defined within the support block 46, extending through the support plate 41. One end of the hinge shaft 44 passes through the support block 46 and is positioned within the active cavity 461, where it is rotatably connected to the main rotating arm 431. This ensures the stability of the hinge shaft while allowing the main rotating arm 431 to move freely within the active cavity.

[0093] The main rotating arm 431 comprises a driven portion 4311 and a pressure portion 4312, which are positioned opposite each other. The driven portion 4311 houses the handrail, while the pressure portion 4312 converts power into pressure against the pressing plate 42. The main rotating arm 431 is connected to the hinge shaft 44 at a corner near the pressure portion 4312. The pressure portion 4312 extends downwardly through the active cavity 461 and is pivotally connected to the piston rod of the pressure cylinder 47, which is tilted at a predetermined angle to the bottom of the support plate 41.

[0094] When the pressure cylinder 47 is activated, its piston rod moves upward, generating an oblique upward thrust on the lower end of the pressure section 4312. Due to the structural characteristics of the main rotating arm 431, this thrust is converted into downward pressure on the driven section 4311 through the principle of leverage. This pressure is ultimately transmitted to the pressing plate 42, which applies a steady pressure to the mesh, thereby ensuring the mesh's flatness and stability during processing.

[0095] See Figure 1 、 Figure 2 and Figure 10 The pretreatment device is movably mounted on one side of a workbench 7 via an integrated bracket 6. The tabletop 71 of the workbench 7 is at the same height as the pressing plate 18. Two rails 72 are arranged vertically and spaced apart along the length of the workbench 7 facing the integrated bracket 6. A slider 61 is provided on the corresponding side of the integrated bracket 6, which is compatible with the rails 72. A rack 73 is provided between the two rails 72, running in the same direction as the rails 72. A third drive motor 62 is arranged horizontally on the integrated bracket 6, with a gear A63 meshing with the rack A73 at its output end. The third drive motor 62 drives the gear A63 to rotate, causing the integrated bracket to move back and forth along the workbench. This device is suitable for warp-breaking operations on mesh fabrics of different specifications, thus efficiently completing the pretreatment work before mesh seams are joined.
