Description

Technical Field

[0001] This utility model relates to the field of knitting machine technology, and more specifically, to a sinker device for knitting machines. Background Technology

[0002] In the field of knitting technology, sinkers are core auxiliary components that work with knitting needles to complete loop formation, holding, and loop release. Their working accuracy directly affects the loop stability, knitting uniformity, and finished product quality of the knitted fabric. As knitting equipment upgrades towards higher speeds and modularity, the traditional sinker structure, which is integrally connected to the machine body, is gradually being replaced by independent sinker mechanisms that can be assembled as a separate module due to difficulties in disassembly and high maintenance costs. These mechanisms can be pre-assembled and debugged before being installed as a whole at the knitting machine station. They offer significant advantages such as convenient assembly and disassembly, strong versatility, and low maintenance costs, and have become the mainstream configuration for flat knitting equipment such as double-needle-bed computerized flat knitting machines.

[0003] Currently, many mainstream knitting machines widely use independent sinker mechanisms. These mechanisms are based on a carrier plate, with multiple sinkers arranged linearly at equal intervals along the length of the needle bed to form an independent sinker assembly module. This module interfaces with the knitting machine main unit through a standardized interface. The drive components on the machine body drive the carrier plate to swing, thereby driving each sinker to move along a set trajectory to complete the knitting operation.

[0004] While this type of configuration has achieved modularity, certain problems still exist in actual high-speed operation. On the one hand, in existing independent sinker assemblies, each sinker and the carrier plate mostly adopt a fixed plug-in or rigid locking structure, lacking a dynamically adjustable support buffer and adaptive positioning design. When the equipment reciprocates at high speed, vibration and impact forces can easily cause slight displacement, loosening, or even tilting of the linearly arranged sinkers, resulting in uneven coil forming, missed needles, sparse or dense patterns, and other weaving defects, seriously affecting fabric quality. On the other hand, the working position and support status of the sinkers in the current module are difficult to adjust online, the disassembly and alignment process is cumbersome, and it is impossible to flexibly adjust the pressing force and movement gap of the sinkers according to different weaving conditions such as yarn material and fabric weight. This results in poor adaptability of the same independent mechanism to different products, limiting the promotion and application of modular sinker devices in multi-category, high-efficiency production scenarios. Therefore, we urgently need a sinker device for knitting machines to solve the above problems. Utility Model Content

[0005] One objective of this invention is to provide a new technical solution for a sinker device for knitting machines. By setting a cam lifting structure with dual working areas and combining it with an elastic locking component, along with a continuous rotating rod cam synchronous transmission and an elastic buffer reset structure, the sinker can be prevented from slipping out during weaving and can be easily manually disassembled when the machine is stopped. At the same time, it improves motion synchronization and operational stability, and reduces component wear and maintenance difficulty.

[0006] According to a first aspect of the present invention, a sinker device for a knitting machine is provided, comprising a mounting plate fixedly mounted on the knitting machine, a driving component on the knitting machine, the driving component being connected to the mounting plate and used to drive the mounting plate to swing along a set motion trajectory, a placement rod fixedly connected to the mounting plate, a slot for placing the sinker being provided on the placement rod, an adjusting component being connected to the sinker inside the placement rod, and an actuating component for moving the sinker being provided on the mounting plate, so as to cooperate with the matching components on the knitting machine to form a knitting area.

[0007] Optionally, the adjusting component includes a rectangular groove formed on the mounting plate and connected to the mounting rod. A first rotating rod is rotatably connected to the rectangular groove via a support seat. A first cam is fixedly installed on the first rotating rod and at the corresponding slot. A bracket for supporting the end of the first rotating rod is fixedly installed on the mounting plate. The knitting machine is connected to the first rotating rod via a motor for driving the first rotating rod and the first cam to rotate around the axis of the first rotating rod.

[0008] Optionally, the bottom wall of the mounting rod cavity is symmetrically provided with telescopic rods, and there are multiple telescopic rods arranged linearly and equidistantly along the length direction of the mounting rod. A support plate is provided in the cavity of the mounting rod, and the bottom of the support plate is connected to the movable end of the telescopic rod. When the first cam abuts against the bottom of the support plate, the telescopic rod and the support plate are in the first working area. When the first cam disengages from the bottom of the support plate, the telescopic rod and the support plate are in the second working area.

[0009] Optionally, the support plate is provided with a flip plate, which is hinged to a hinge seat on the support plate. An elastic support assembly is symmetrically installed on the support plate. The elastic support assembly consists of two sets of elastic plates, one side of which is connected to the flip plate, and the other side of which is connected to the support plate. A sliding groove is provided on the flip plate, and a mounting seat is slidably connected to the flip plate. The end of the mounting seat is slidably connected within the sliding groove. A tension spring is provided within the sliding groove, and both ends of the tension spring are respectively connected to the inner wall of the sliding groove and the mounting seat.

[0010] Optionally, the mounting base has a first insertion groove for placing a settling plate, and the mounting base also has a second insertion groove that communicates with the first insertion groove. The inner wall of the first insertion groove is fixedly connected with a gasket for pressing against the settling plate. The length of the first insertion groove is greater than the length of the second insertion groove. The first insertion groove and the second insertion groove form a T-shaped slot in the mounting base to limit and fix the settling plate.

[0011] Optionally, the second insertion slot is provided with a clamping member for fixing the settling piece. The clamping member includes circular holes symmetrically opened in the second insertion slot, a clamping ball is provided in the circular hole, and a spring is provided in the circular hole. The two ends of the spring are respectively connected to the inner wall of the circular hole and the clamping ball to form an elastic clamping area.

[0012] Optionally, the settling plate is integrally formed with a plug-in piece that is adapted to the second plug-in groove. The plug-in piece is symmetrically provided with notches. When the abutment ball is inserted into the notch, a positioning area for the settling plate is formed.

[0013] Optionally, the actuating element includes a second rotating rod disposed on the mounting plate. The second rotating rod is rotatably connected to a stand on the mounting plate. A second cam is fixedly installed on the second rotating rod at the location corresponding to the sinker. The knitting machine is connected to the end of the second rotating rod via a motor. When the motor drives the second rotating rod to rotate and drives the second cam to rotate synchronously, the sinker moves along the pushing path of the second cam to form a swing zone. When in the swing zone, the flip plate compresses the elastic sheet to form an elastic support and reset zone.

[0014] 1. According to one embodiment of this disclosure, the sinker device of the double needle bed knitting machine uses an installation plate as an independent modular support base. It is combined with a mounting rod, a telescopic rod, a support plate, and a first cam to form a switchable dual working area structure. The height change of the first cam's rotation profile controls the lifting and lowering of the support plate. In the first working area, the sinker can be raised to change the vertical installation spacing, forming physical spatial interference. This effectively limits the sinker from loosening, shifting, or being accidentally pulled out under high-speed weaving conditions, ensuring that the sinker's position remains constant and reliable during the weaving process. In the second working area, the sinker can be lowered to release the spatial interference constraint. Combined with the elastic locking structure inside the second insertion slot, which consists of a circular hole, a spring, and a retaining ball, the sinker can be disassembled and replaced by manual pulling without disassembling the entire machine. At the same time, the mounting rod conceals the adjustment component inside, effectively preventing fly yarn and yarn debris from entangled and jamming the internal moving components during weaving. This not only improves the reliability of continuous equipment operation but also greatly simplifies the later maintenance and disassembly process, reducing maintenance time and operational difficulty.

[0015] 2. According to one embodiment of this disclosure, the sinker device of the double needle bed knitting machine adopts a continuous layout of the first and second rotating rods and integrates multiple sets of first and second cams respectively. It synchronously drives the entire row of sinkers to complete the height adjustment and knitting swing action by relying on pure mechanical linkage, eliminating multiple sets of independent drive control components, greatly simplifying the overall transmission layout of the machine, and ensuring that the actions of multiple sets of sinkers are synchronized and consistent. At the same time, the flip plate and elastic plate form an elastic buffer reset structure, and the internal tension spring of the slide groove automatically returns the mounting seat to its original position. This can effectively absorb the mechanical impact generated by the reciprocating swing of the sinkers, reduce the friction and wear of metal components and abnormal noise during operation, and limit the sinkers in multiple directions through the T-shaped slot formed by the first and second insertion slots on the mounting seat, avoiding shaking and deflection during operation. This significantly improves the matching accuracy between the sinkers and the knitting needles and the fabric forming quality, and can also effectively extend the service life of each transmission and moving component, adapting to the use requirements of long-term continuous high-speed production of double needle bed knitting machines.

[0026] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0027] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] like Figure 1-7 As shown, a sinker plate 3 device for a knitting machine includes a mounting plate 1 fixedly installed on the knitting machine. A driving component is provided on the knitting machine and connected to the mounting plate 1 to drive the mounting plate 1 to swing along a set motion trajectory.

[0031] Here, the mounting plate 1 serves as the overall load-bearing base and installation reference of the device. It adopts an independent modular structure and is fixedly assembled on the knitting machine. It is not integrally formed with the knitting machine body. The assembly and position calibration of each component can be completed in advance before the overall alignment and installation. The drive component of the knitting machine forms a reliable transmission connection with the mounting plate 1, providing the power required for the overall swing of the mounting plate 1 and all the supporting components above it, so as to realize the synchronous trajectory movement of the entire plate component.

[0032] Furthermore, the mounting plate 1 adopts a flat and regular structure, which can provide a flat and reliable mounting base for functional components such as mounting rod 2, adjusting parts, and actuating parts. Each component can be arranged linearly and orderly along the length of the mounting plate 1, with a compact and reasonable layout. There is no mutual interference between the moving parts during operation, which is suitable for the linear needle bed layout of flat knitting machines.

[0033] Furthermore, by adopting a transmission method in which the drive component directly drives the overall swing of the mounting plate 1, all the settling plates 3 on the plate can move synchronously, eliminating the complex structural layout of driving each settling plate 3 independently, simplifying the transmission link of the whole machine, ensuring the consistency of movement of multiple sets of settling plates 3, reducing wear of transmission components, and extending the overall service life of the device.

[0034] Mounting plate 1 is fixedly connected to a mounting rod 2, which has a slot 4 for placing a settling plate 3. The mounting rod 2 is connected to the settling plate 3 through an adjusting component.

[0035] Here, the mounting rod 2 is fixed to the upper part of the mounting plate 1, serving as a dedicated support and placement component for the settling plate 3. The slot 4 is opened along the length of the mounting rod 2, providing a limiting and accommodating space for the settling plate 3, ensuring that the settling plate 3 is neatly inserted in a defined posture. The adjustment component is internally arranged inside the cavity of the mounting rod 2, realizing the structural linkage between the mounting rod 2 and the settling plate 3, and allowing adaptive adjustment of the working height and limiting state of the settling plate 3.

[0036] Furthermore, the mounting rod 2 is rigidly fixed to the mounting plate 1, resulting in strong overall structural stability and no relative displacement or angular deviation during operation. The slot 4 is precisely aligned with the mounting base 14 and the actuating component of the settling plate 3, forming a corresponding assembly relationship and ensuring the positional accuracy of the settling plate 3 after assembly.

[0037] Furthermore, the adjustment components are concealed inside the mounting rod 2, unlike exposed adjustment structures. This saves external installation space and prevents fly shavings and yarn debris from getting tangled and jamming moving parts during weaving, thus improving the stability of continuous operation of the mechanism. It also facilitates the cleaning of debris inside the cavity and routine maintenance.

[0038] The adjusting component includes a rectangular groove 5 on the mounting plate 1 that communicates with the mounting rod 2. A first rotating rod 6 is rotatably connected to the rectangular groove 5 via a support seat. A first cam 7 is fixedly installed on the first rotating rod 6 and at the corresponding slot 4. A bracket 8 for supporting the end of the first rotating rod 6 is fixedly installed on the mounting plate 1. A motor is connected to the first rotating rod 6 on the knitting machine to drive the first rotating rod 6 and the first cam 7 to rotate around the axis of the first rotating rod 6.

[0039] Here, a rectangular slot 5 is formed on the surface of the mounting plate 1 and communicates with the cavity of the mounting rod 2, providing assembly clearance space for the first rotating rod 6. The internal support seat of the rectangular slot 5 forms a rotational support for the middle section of the first rotating rod 6, which, together with the brackets 8 fixed at both ends of the mounting plate 1, forms a multi-point support structure to ensure that the first rotating rod 6 rotates smoothly around its own axis. The first cam 7 is arranged one-to-one with each slot 4, matching the work position below each set of sinkers 3, and the matching motor provides stable power input for the rotation of the first rotating rod 6.

[0040] Furthermore, the first rotating rod 6 adopts a continuous integrated structure, and multiple sets of first cams 7 can be fixed on a single rod body at the same time. When the rotating rod rotates, it can drive the lifting and adjusting structure corresponding to multiple sets of settling plates 3 at the same time. There is no need to set up a separate driving component for a single set of settling plates 3. The structure has a high degree of integration and the adjustment actions of each group are well synchronized.

[0041] Furthermore, a purely mechanical transmission adjustment structure is adopted, consisting of a motor, a first rotating rod 6, and a first cam 7. This structure ensures precise and stable transmission, is less affected by dust, temperature, and humidity in the weaving environment, and has better environmental adaptability than electronic control adjustment methods. The bracket 8 and the intermediate support form a multi-point limiting support, which can effectively suppress the flexural deformation, rotational jamming, and abnormal noise caused by the long-term rotation of the first rotating rod 6, maintaining adjustment accuracy and smooth operation under long-term continuous working conditions.

[0042] The bottom wall of the cavity of the mounting rod 2 is symmetrically provided with multiple telescopic rods 9, which are arranged linearly and equidistantly along the length of the mounting rod 2. A support plate 10 is provided inside the cavity of the mounting rod 2. The bottom of the support plate 10 is connected to the movable end of the telescopic rod 9. When the first cam 7 abuts against the bottom of the support plate 10, the telescopic rod 9 and the support plate 10 are in the first working area. When the first cam 7 disengages from the bottom of the support plate 10, the telescopic rod 9 and the support plate 10 are in the second working area.

[0043] Here, multiple sets of telescopic rods 9 are symmetrically arranged on the bottom wall of the cavity of the mounting rod 2, and are equidistant along the length of the rods, forming a balanced vertical support and vertical movement guide for the support plate 10, limiting the support plate 10 to only vertical lifting and lowering displacement, and avoiding problems of offset, tilting and movement jamming. The support plate 10 is supported under all the settling plates 3 and rises and falls synchronously with the telescopic rods 9. The first cam 7 achieves pressure support or force relief separation on the bottom of the support plate 10 by changing the height of its rotational profile, thereby switching between two working operating states.

[0044] Furthermore, the equidistant telescopic rods 9 can evenly distribute the vertical load of the support plate 10, avoid uneven local stress causing warping of the plate surface, ensure the overall horizontal lifting of the support plate 10, and keep the lifting height of each set of sinking plates 3 above consistent, preventing misalignment from affecting the weaving accuracy.

[0045] Furthermore, when in the first working zone, the first cam 7 presses against the support plate 10 and lifts it, causing the sinker plate 3 to move upwards synchronously, reducing the vertical distance between the sinker plate 3 and the upper frame, forming mechanical spatial interference, and restricting the sinker plate 3 from coming off, thus meeting the anti-loosening requirements under weaving conditions. When in the second working zone, the first cam 7 disengages from the unloading force, the support plate 10 falls back with the telescopic rod 9, and the sinker plate 3 moves downwards synchronously. The vertical interference constraint is released, leaving only the elastic locking limit, allowing the sinker plate 3 to be removed manually without disassembling the entire machine structure, making disassembly and maintenance operations simple.

[0046] A flip plate 11 is provided on the support plate 10. The flip plate 11 is hinged to the hinge seat on the support plate 10. Elastic support groups are symmetrically installed on the support plate 10. The elastic support groups are composed of two sets of elastic plates 12. One side of the elastic plate 12 is connected to the flip plate 11, and the other side of the elastic plate 12 is connected to the support plate 10. A sliding groove 13 is provided on the flip plate 11. A mounting seat 14 is slidably connected on the flip plate 11. The end of the mounting seat 14 is slidably connected in the sliding groove 13. A tension spring 15 is provided in the sliding groove 13, and the two ends of the tension spring 15 are respectively connected to the inner wall of the sliding groove 13 and the mounting seat 14. The mounting base 14 has a first insertion groove 16 for placing the settling plate 3. The mounting base 14 also has a second insertion groove 17 that communicates with the first insertion groove 16. A gasket 18 for pressing against the settling plate 3 is fixedly connected to the inner wall of the first insertion groove 16. The length of the first insertion groove 16 is greater than the length of the second insertion groove 17. The first insertion groove 16 and the second insertion groove 17 form a T-shaped slot 4 in the mounting base 14.

[0047] Here, the flip plate 11 is hinged to the support plate 10 via a hinged seat, allowing for a small amount of flipping movement. Two sets of elastic plates 12 are symmetrically arranged to form an elastic support group, which normally maintains the posture of the flip plate 11 and provides buffering and rebound force after flipping deformation. The slide groove 13 is opened on the surface of the flip plate 11 to provide a horizontal sliding guide for the mounting base 14. The tension spring 15 is located inside the slide groove 13 and is only used to drive the mounting base 14 to slide and reset, and does not participate in the locking and unlocking control of the sinking plate 3. The first insertion groove 16 and the second insertion groove 17 are connected and have different lengths, forming a T-shaped slot 4 inside the mounting base 14, which is adapted to the shape of the lower insertion structure of the sinking plate 3. The gasket 18 is fixed to the inner wall of the first insertion groove 16, which plays a role in fitting tightly, buffering and shock absorption.

[0048] Furthermore, the flip plate 11, elastic plate 12, and mounting base 14 constitute independent modular units. Each set of settling plates 3 corresponds to an independent component, and each unit does not interfere with each other and can be disassembled, repaired, or replaced individually. The T-shaped slot 4 can provide multi-directional limiting constraints on the settling plates 3, suppressing shaking and displacement during operation. The gasket 18 can reduce wear from hard metal contact and lower operating noise.

[0049] Furthermore, when the tilting plate 11 swings and deflects angularly with the settling plate 3, the elastic plate 12 undergoes elastic deformation, which can buffer the vibration and impact generated by the reciprocating motion of the weaving, and achieve automatic posture reset by its own elasticity. The tension spring 15 can drive the mounting base 14 back to the initial reference position along the slide groove 13 without the need for manual alignment and calibration. The entire mating structure has small movement clearance and high assembly precision, and is not prone to loosening or play during long-term use, thus continuously ensuring the assembly and movement matching precision of the settling plate 3.

[0050] The second insertion groove 17 is provided with a clamping member for fixing the settling piece 3. The clamping member includes circular holes 19 symmetrically opened in the second insertion groove 17. A clamping ball 20 is provided in the circular hole 19. A spring 21 is provided in the circular hole 19. The two ends of the spring 21 are respectively connected to the inner wall of the circular hole 19 and the clamping ball 20 to form an elastic clamping area. The settling piece 3 is integrally formed with an insertion piece 22 that is adapted to the second insertion groove 17. The insertion piece 22 is symmetrically provided with notches 23. When the clamping ball 20 is inserted into the notch 23, a positioning area for the settling piece 3 is formed.

[0051] Here, the clamping element is integrally arranged inside the wall of the second insertion slot 17, and the symmetrically opened circular holes 19 provide installation and accommodating space for the clamping ball 20 and the spring 21. The spring 21 always applies an elastic thrust within the circular hole 19, keeping the clamping ball 20 in an extended and clamped state. The integrally formed insertion piece 22 of the sinker plate 3 can be fitted and inserted into the second insertion slot 17, and the symmetrically opened notches 23 on the side wall of the insertion piece 22 can cooperate with the clamping ball 20 to achieve locking and positioning.

[0052] Furthermore, the symmetrically arranged clamping balls 20 and springs 21 can form a balanced elastic clamping and limiting of the insert piece 22 from both sides, ensuring uniform force distribution without any loosening or displacement on one side. The clamping balls 20 and notches 23 adopt a spherical mating structure, which facilitates the insertion of the insert piece 22 into place and allows for smooth avoidance during manual disassembly.

[0053] Furthermore, an elastic locking structure is adopted, in which the spring 21 pushes the ball 20 into the notch 23, eliminating the need for additional bolts and fasteners, resulting in a simple and reliable assembly structure. When manually disassembling the settling piece 3, the side wall of the insert piece 22 can squeeze the ball 20 to compress the spring 21, thus avoiding movement. Under normal weaving conditions, this effectively limits the lateral movement of the settling piece 3, balancing assembly stability with ease of disassembly and assembly.

[0054] The mounting plate 1 is provided with a toggle element for moving the sinker plate 3, which cooperates with the matching components on the knitting machine to form a knitting area. The toggle element includes a second rotating rod 24 provided on the mounting plate 1. The second rotating rod 24 is rotatably connected to the upright on the mounting plate 1. A second cam 25 is fixedly installed on the second rotating rod 24 corresponding to the sinker plate 3. The knitting machine is connected to the end of the second rotating rod 24 through a motor. When the motor drives the second rotating rod 24 to rotate and drives the second cam 25 to rotate synchronously, the sinker plate 3 moves along the pushing path of the second cam 25 to form a swing area. When in the swing area, the flip plate 11 compresses the elastic plate 12 to form an elastic support and reset area.

[0055] Here, the actuating element is positioned on the mounting plate 1 corresponding to the movement path of the settling piece 3, serving as a dedicated transmission structure for driving the settling piece 3 to weave and swing. The second rotating rod 24 is rotatably mounted on the mounting plate 1 via a support frame. The second cam 25 is fixed to the rod body corresponding to the positions of each set of settling pieces 3. An external motor provides power for the rotation of the second rotating rod 24. The second cam 25 drives the settling piece 3 to reciprocate and swing based on its contour trajectory, forming a working swing area. During the swinging process, the settling piece 3 drives the flipping plate 11 to move and compresses the elastic plate 12, forming a stable elastic support and deformation recovery structure area.

[0056] Furthermore, the second rotating rod 24 adopts a continuous layout, which can drive multiple sets of second cams 25 to rotate synchronously, realizing the synchronous swing operation of the entire row of sinker plates 3. It has good transmission synchronization and is suitable for the overall knitting operation requirements of the needle bed. The upright frame independently supports the second rotating rod 24 and is firmly assembled with the mounting plate 1, with no shaking or positional deviation during rotation.

[0057] Furthermore, the mechanical actuation structure combining the second rotating rod 24 and the second cam 25 offers strong controllability in swing stroke and motion trajectory, enabling stable driving of the sinker 3 and the knitting needle to precisely coordinate and complete the loop-forming process. When the sinker 3 swings, it links the flip plate 11 to compress the elastic plate 12. The deformation of the elastic plate 12 absorbs the impact of the motion and stores potential energy. After the cam disengages from the push, it can automatically reset, eliminating the need for additional reset drive components, simplifying the structure and improving operational stability.

[0058] The working principle of this utility model is as follows: In this embodiment, the settling plate 3 device is independently and modularly assembled on the knitting machine with the mounting plate 1 as the overall base. The driving component of the knitting machine can drive the mounting plate 1 to swing along the set motion trajectory. The mounting rod 2 is set on the mounting plate 1. The T-shaped groove formed by the slot 4 and the first insertion slot 16 and the second insertion slot 17 is used to limit the placement of the settling plate 3. After the insertion piece 22 of the settling plate 3 is inserted into the groove, the spring 21 inside the circular hole 19 will push the retaining ball 20 into the notch 23 of the insertion piece 22 to achieve elastic locking. 18 acts as a buffer, and the motor drives the first rotating rod 6 to rotate the first cam 7 synchronously. When the protruding contour of the first cam 7 presses against the bottom of the support plate 10, it works in conjunction with multiple sets of telescopic rods 9 to lift the support plate 10 to the first working area, causing the sinker 3 to move upward synchronously, reducing the distance between the sinker 3 and the upper frame, forming a spatial interference restriction, preventing the sinker 3 from being pulled out, and ensuring that the sinker 3 accurately reaches the weaving working position, ensuring that the position is stable and does not shift during the weaving process. When the contour of the first cam 7 rotates away from the support plate 10, the support plate 10 falls back with the telescopic rods 9. In the second working area, the sinker plate 3 descends, increasing the distance between it and the upper frame, thus eliminating spatial interference. Only the conventional elastic locking position of the retaining ball 20 remains, allowing workers to manually pull out the sinker plate 3. Disassembly and maintenance are very convenient. The mounting plate 1 is also equipped with a push structure that can move along the plate surface. Driven by a drive motor through a gear rack and guide rail, the pusher rod is displaced and pushes the sinker plate 3 during normal weaving operation, causing it to move along the track of the slide groove 13 and cooperate with the knitting needles to complete the looping, holding, and loop-unlocking processes. During the movement of the sinker plate 3, it will rotate. The plate 11 rotates slightly and squeezes the elastic plates 12 on both sides. The elastic plates 12 are used to achieve buffering and rebound reset. The tension spring 15 set inside the slide groove 13 is only used to drive the mounting base 14 to slide reset. It does not participate in the unlocking, locking and limiting action of the sinker 3. The overall device structure is reasonably laid out. It can switch the working position and disassembly state of the sinker 3 through the cam linkage lifting structure, which meets the dual requirements of weaving limit and anti-pull-out and convenient manual disassembly when stopping the machine. It also uses the gear and rack actuation mechanism to achieve precise linkage between the sinker 3 and the knitting needle during normal weaving. It is stable in operation and easy to maintain.
