Description

Technical Field

[0001] This invention relates to the field of warp knitting machine technology, and in particular to a settling mechanism and control method for a double needle bed warp knitting machine. Background Technology

[0002] In the current era of rapid development in the textile industry, double-needle bed warp knitting machines, as the core carrier for producing knitted fabrics, directly affect the overall efficiency of the textile supply chain through their production efficiency and knitting quality. The sinking mechanism, as a key loop-forming component of the double-needle bed warp knitting machine, directly determines the knitting quality, texture accuracy, and subsequent processing efficiency of the fabric. The sinking mechanism achieves the pressing and unlocking of old loops through the reciprocating oscillation of the sinking plate, which directly determines the knitting quality of the fabric.

[0003] The existing settling mechanism of a double-needle bed warp knitting machine includes a settling plate holder, a settling plate, a drive assembly, a guide assembly, and an adjustment assembly. During operation, the warp yarns are first threaded into the needle holes of the double-needle bed warp knitting machine according to process requirements, ensuring uniform warp yarn tension and neat arrangement. Then, the initial position of the settling plate is calibrated using the adjustment assembly, ensuring precise matching of the settling plate with the needle bed's needle pitch and needle type. Next, the drive assembly is activated, causing the settling plate holder to reciprocate, and the settling plate to oscillate synchronously, ensuring that the old loops are tightly fitted to the needle bar, preventing loosening and deformation of the loops, and forming a continuous knitted texture.

[0004] In the above structure, when the settling mechanism is running at high speed for a long time, the guide component moves continuously at high frequency with the settling seat. The frequent relative friction between the guide rod and the guide cylinder generates a lot of heat, causing the local temperature to rise continuously. As the working time increases, the guide rod expands axially and radially due to heat, causing the fit gap between it and the guide cylinder to continuously decrease or even completely fit together. This results in a sharp increase in movement resistance and jamming, which directly causes the settling seat to not move into place. Ultimately, this leads to disordered pressing and unpressing sequence, uneven fabric stripes, missed needles, and skewed loops, which seriously affect the weaving accuracy and production stability. Summary of the Invention

[0005] To prevent the guide rod from expanding axially and radially due to heat, which could cause the settling seat to fail to move into place, this invention provides a settling mechanism and its control method for a double needle bed warp knitting machine.

[0006] In a first aspect, the present invention provides a settling mechanism for a double-needle bed warp knitting machine, which adopts the following technical solution: A settling mechanism for a double needle bed warp knitting machine includes a settling seat, a drive assembly mounted on the warp knitting machine for driving the settling seat to move up and down, and a cooling mechanism for lubrication, cooling and temperature reduction. The cooling mechanism includes a cooling box mounted on the warp knitting machine, a bidirectional screw rotatably mounted in the cooling box, a piston plate threadedly connected to the bidirectional screw and slidably mounted in the cooling box, a conveying assembly mounted on the cooling box for conveying coolant, a shifting assembly mounted on the warp knitting machine for driving the bidirectional screw to rotate when the drive assembly is started, and a triggering assembly mounted on the cooling box for triggering the shifting assembly to work to achieve lubrication, cooling and temperature reduction.

[0007] By adopting the above technical solution, after the trigger component senses the expansion of the guide rod, it drives the shift component to link with the cooling mechanism. The bidirectional screw drives the piston plate to squeeze and supply liquid, thereby achieving lubrication, cooling and reducing the temperature of the guide rod, and fundamentally avoiding the problem of the sinker not moving in place due to the thermal expansion of the guide rod.

[0008] Optionally, it also includes a settling plate installed on the settling seat and a guide assembly installed on the warp knitting machine for guiding the settling seat during lifting and lowering; The guiding assembly includes a guide cylinder mounted on the warp knitting machine and a guide rod mounted on the settling seat and slidably mounted inside the guide cylinder; the guide rod has a conveying cavity inside, and a plurality of liquid infusion holes are formed on the surface of the guide rod and communicate with the conveying cavity; The delivery assembly includes a suction pipe connected to the cooling tank and a delivery pipe connected between the suction pipe and the delivery chamber; a one-way valve structure is provided at the connection between the suction pipe and the cooling tank to prevent coolant backflow; When the conveying assembly is in operation, it delivers coolant into the conveying chamber and discharges it from the inlet to lubricate and cool the guide rod and the guide cylinder.

[0009] By adopting the above technical solution, the guide cylinder and guide rod ensure accurate lifting and stable movement of the settling seat. At the same time, the guide rod has a built-in delivery cavity and liquid inlet, so that the coolant can evenly and directly wet the mating surface, thereby lubricating and cooling the guide rod. In addition, the one-way valve structure prevents the coolant from flowing back, ensuring stable liquid supply pressure.

[0010] Optionally, the drive assembly includes a drive shaft rotatably mounted on the warp knitting machine, a drive motor mounted on the warp knitting machine for driving the drive shaft to rotate, and a drive cam mounted on the drive shaft for driving the sinker to rise and fall. The shifting assembly includes a shifting shaft rotatably mounted on a warp knitting machine, a synchronization structure for driving the shifting shaft to rotate synchronously with the drive shaft, and a shifting ring mounted on the synchronization structure for driving the bidirectional screw to rotate synchronously with the shifting shaft.

[0011] By adopting the above technical solution, the cooperation between the drive motor, drive shaft and drive cam enables the sinking seat to reciprocate and rise, meeting the requirements of the ring forming process. At the same time, the shift shaft and synchronization structure can be started by the drive assembly, without the need for an additional drive source, reducing costs. Furthermore, the power on / off is achieved through the shift ring, allowing the cooling mechanism to be started and stopped as needed, avoiding waste caused by continuous liquid supply.

[0012] Optionally, the synchronization structure includes a synchronization pulley connected by a key to the shift shaft and the drive shaft, and a synchronization belt sleeved on the two synchronization pulleys and used to drive the two synchronization pulleys to rotate synchronously. A shift disc is installed at one end of the bidirectional screw near the synchronous pulley, and a shift groove matching the shift ring is opened on the side of the shift disc near the shift ring. Both of the synchronous pulleys are provided with annular grooves, and a shift bracket is slidably installed in the annular grooves. The shift bracket is connected to the trigger component to drive the shift component to work.

[0013] By adopting the above technical solution, the synchronous pulley and synchronous belt realize the synchronous transmission of power between the drive shaft and the shift shaft without the need for an additional power source. At the same time, the power of the cooling mechanism is turned on and off through the cooperation of the shift plate and the shift groove, thereby realizing the on-demand start and stop of the cooling mechanism. Furthermore, the shift bracket slides along the annular groove, which can accurately receive trigger signals and control the engagement of the shift ring, ensuring stable and reliable transmission switching.

[0014] Optionally, the trigger assembly includes a protective plate mounted on the cooling box, a starter plate slidably mounted on the protective plate, a connecting plate mounted on the starter plate, a trigger half-ring mounted on the connecting plate and used to frame the guide rod, a gear rack structure mounted on the starter plate, a trigger plate mounted on the gear rack structure and mounted on the shift assembly, and a force-applying rod hinged between the connecting plate and the trigger plate.

[0015] By adopting the above technical solution, the trigger half-ring directly fits into the guide rod, which can sense the thermal expansion deformation of the guide rod in real time. Then, through the gear and rack structure and the force rod, a lever amplification mechanism is formed to convert the small deformation of the guide rod into a large movement of the shifting component. At the same time, the protective plate and the sliding structure ensure that the triggering process is stable and without jamming, and realize automatic triggering of lubrication and cooling when the temperature expands.

[0016] Optionally, the cooling box is equipped with a limiting component for limiting and guiding the movement of the connecting plate; The limiting assembly includes a limiting block installed on the cooling box and a limiting telescopic column installed between the limiting block and the connecting plate for limiting and guiding the movement of the connecting plate; a compression spring is sleeved on the outer side of the limiting telescopic column, one end of the compression spring is connected to the connecting plate, and the other end of the compression spring is connected to the limiting block, and the compression spring drives the connecting plate and the trigger half ring to always tend to move closer to the guide rod.

[0017] By adopting the above technical solution, the limiting block and the limiting telescopic column limit and guide the connecting plate to avoid the trigger half ring from shifting. At the same time, the compression spring keeps the trigger half ring in close contact with the guide rod, ensuring the expansion detection accuracy and providing the reset driving force so that the trigger half ring can automatically reset after the guide rod cools and contracts, disconnecting the lubrication cooling transmission, realizing on-demand lubrication cooling and reducing energy consumption and coolant waste.

[0018] Optionally, the guide rod is equipped with a collection assembly for collecting the used coolant; The converging assembly includes a converging disc mounted on the guide rod and a telescopic cover mounted between the guide cylinder and the converging disc; the converging disc, the guide cylinder, and the telescopic cover together enclose a converging chamber.

[0019] By adopting the above technical solution, the collecting plate, guide cylinder and telescopic cover form a closed collecting chamber, which collects the used coolant to prevent leakage and pollution. When the guide rod reciprocates, it drives the telescopic cover to extend and retract synchronously, thereby enabling the coolant in the collecting chamber to circulate, lubricate and cool down, thereby improving the coolant utilization rate and reducing coolant splashing.

[0020] Secondly, this application provides a control method for the settling mechanism of a double-needle bed warp knitting machine, employing the following technical solution: A control method for the settling mechanism of a double needle bed warp knitting machine, applied to the settling mechanism of a double needle bed warp knitting machine, comprising: Obtain real-time temperature information of the guide components; Based on the comparison between real-time temperature information and preset reference temperature information, determine whether the mating part between the guide rod and the guide cylinder is in a state requiring high-temperature lubrication and cooling, and collect the deformation of the guide assembly; When the deformation of the guide component reaches the preset reference deformation, the shift component and the cooling mechanism are triggered to work together to control the piston plate to squeeze the coolant at a preset extrusion rate so as to continuously deliver the coolant to the space between the guide rod and the guide cylinder for lubrication, cooling and temperature reduction. When the deformation of the guide component does not reach the preset reference deformation, the control shift component disconnects the transmission, and the cooling mechanism stops supplying liquid.

[0021] By adopting the above technical solution, temperature deformation is judged in two ways to accurately identify the high-temperature lubrication and cooling requirements. When the reference deformation is reached, lubrication and cooling are automatically activated. If the reference deformation is not reached, the liquid supply is automatically stopped, realizing intelligent on-demand lubrication and cooling. This avoids the guide rod from getting stuck due to thermal expansion and reduces ineffective liquid supply.

[0022] Optional, also includes: The actual temperature of the coolant in the collecting chamber, the volume of the coolant in the collecting chamber, and the initial temperature of the coolant in the cooling tank are collected. Match the deformation infusion volume according to the deformation of the guide component; The theoretical temperature of the mixed coolant is determined based on the initial temperature, actual temperature, pool volume, and deformed fluid delivery volume. When the theoretical temperature is higher than the preset reference working fluid temperature, the coolant in the collecting chamber is completely discharged into the collection tank, and the coolant in the deformed fluid delivery volume is delivered to the guide assembly. When the theoretical temperature is not higher than the reference working fluid temperature, a portion of the coolant in the collecting chamber is discharged to the collection tank at a preset discharge rate, and coolant of the deformed fluid delivery volume is delivered to the guide assembly.

[0023] By adopting the above technical solution, the mixing theoretical temperature is calculated based on the coolant temperature and volume, and the draining strategy is intelligently determined, so that the high-temperature coolant is completely drained and the low-temperature coolant is partially drained, thereby taking into account both the lubrication and cooling effect and the coolant saving effect. Moreover, the drained coolant can be filtered and recycled to achieve recycling, avoiding the coolant temperature from being too high and affecting the lubrication and cooling effect, and ensuring the fabric weaving quality.

[0024] Optional, also includes: Obtain the real-time volume inside the cooling box; Determine the amount of deformable infusion fluid supplied based on the deformable infusion volume; When the real-time volume is less than the deformation infusion supply, the temperature of the recovered coolant in the collection tank is collected. When the temperature of the recovered liquid is lower than the reference working liquid temperature, all the coolant in the collection tank will be transferred to the cooling tank. When the temperature of the recovered liquid is not lower than the reference working liquid temperature, the theoretical threshold volume is obtained based on the real-time volume, the reference working liquid temperature, the recovered liquid temperature, and the initial temperature. The replenishment volume is determined based on the deformation infusion supply and real-time volume. When the replenished volume is lower than the theoretical threshold volume, the theoretical threshold volume is transferred to the cooling box; When the replenished volume is not lower than the theoretical threshold volume, the machine is shut down and coolant at the initial temperature is refilled into the cooling tank.

[0025] By adopting the above technical solution, the coolant level in the tank is monitored in real time. When the coolant level is insufficient, it is automatically recovered and replenished. The recovered coolant is then processed according to its temperature: full replenishment is given for low temperatures and limited replenishment is given for high temperatures. This prevents high-temperature coolant from affecting the lubrication and cooling system. When the coolant level is too low, the system automatically shuts down to remind the user to replace the coolant, ensuring the safety and stability of the lubrication and cooling system.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. After the trigger component senses the expansion of the guide rod, it drives the shifting component to link with the cooling mechanism. The bidirectional screw drives the piston plate to squeeze and supply liquid, thereby achieving lubrication, cooling and reducing the temperature of the guide rod, and fundamentally avoiding the problem of the sinker not moving in place due to the thermal expansion of the guide rod; 2. By directly attaching the trigger half-ring to the guide rod, the thermal expansion deformation of the guide rod can be sensed in real time. Then, through the gear and rack structure and the force rod, a lever amplification mechanism is formed to convert the small deformation of the guide rod into a large movement of the shifting component. At the same time, the protective plate and sliding structure ensure that the triggering process is stable and without jamming, and realize automatic triggering of lubrication and cooling when the temperature expands. 3. A closed collection chamber is formed by the collection plate, guide cylinder and telescopic cover to collect the used coolant and prevent leakage and pollution. When the guide rod reciprocates, it drives the telescopic cover to extend and retract synchronously, so that the coolant in the collection chamber can be circulated for lubrication and cooling, thereby improving the coolant utilization rate and reducing coolant splashing.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] This application discloses a settling mechanism for a double needle bed warp knitting machine.

[0031] Reference Figure 1 as well as Figure 2 A settling mechanism for a double needle bed warp knitting machine includes a settling seat 1, a settling plate 2, a guide assembly 5, a drive assembly 3, and a cooling mechanism 4.

[0032] The sinker 1 is mounted on the warp knitting machine, and the sinker plate 2 is fixedly mounted on the sinker 1, cooperating with the knitting needles to complete the knitting of the fabric. The guide assembly 5 is mounted on the warp knitting machine and is used to guide the sinker 1 during its lifting and lowering. The drive assembly 3 is mounted on the warp knitting machine and is used to drive the sinker 1 to lift and lower. The cooling mechanism 4 is mounted on the warp knitting machine and is used to lubricate, cool, and reduce the temperature of the guide assembly 5.

[0033] During operation, the drive component 3 is activated to drive the sinker 1 to reciprocate up and down along the guide component 5. The sinker 2 moves synchronously with the sinker 1, pressing and assisting the old coil to unwind as the needle winds the new coil, ensuring uniform coil formation and regular fabric texture.

[0034] When the sinker 1 is continuously raised and lowered, the cooling mechanism 4 is triggered and started simultaneously, continuously supplying coolant to the sliding engagement part of the guide component 5, thereby ensuring the smooth movement of the sinker 1, so that the sinker plate 2 and the knitting needle always maintain precise action coordination, improving the knitting accuracy and production continuity of the knitted fabric.

[0035] In this embodiment, there are two settling seats 1 and multiple settling plates 2, with multiple settling plates 2 fixedly installed on the corresponding settling seats 1.

[0036] Reference Figure 2 The drive assembly 3 includes a drive shaft 31, a drive motor 32, and a drive cam 33. The drive motor 32 is fixedly mounted on the warp knitting machine, and the drive shaft 31 is rotatably mounted on the warp knitting machine and fixedly connected to the output end of the drive motor 32 via a coupling. The drive cam 33 is fixedly mounted on the drive shaft 31, and a first hinge seat 34 and a second hinge seat 35 are respectively hinged on the drive cam 33. A first support rod 36 and a second support rod 37 are rotatably mounted on the warp knitting machine.

[0037] The first hinge seat 34 is fixedly installed on the first support rod 36, and the second hinge seat 35 is fixedly installed on the second support rod 37. Two rotating seats 38 are fixedly installed on the first support rod 36, and rotating rods 381 are hinged to both rotating seats 38. The other end of the two rotating rods 381 is hinged to one of the settlement seats 1. The second hinge seat 35 is hinged to a hinge rod 39, and the other end of the hinge rod 39 is hinged to the other settlement seat 1.

[0038] The hinge points of the first hinge seat 34 and the second hinge seat 35 are symmetrically arranged on the drive cam 33, so that the first hinge seat 34 and the second hinge seat 35 can rise alternately, thereby driving the two sinker seats 1 to rise and fall alternately, and in turn driving the sinker plate 2 to rise and fall alternately, so that the sinker plate 2 and the knitting needle always maintain precise action coordination.

[0039] During operation, the drive motor 32 is started, driving the drive shaft 31 to rotate at a constant speed, thereby driving the drive cam 33 to rotate. When the drive cam 33 rotates to the hinge point of the first hinge seat 34, it pushes the first hinge seat 34 to move upward. Since the first hinge seat 34 is fixed on the first support rod 36, the first support rod 36 rotates synchronously around the installation point of the warp knitting machine with the first hinge seat 34. The two rotating seats 38 fixed on the first support rod 36 swing synchronously. The two rotating rods 381 swing synchronously under the drive of the rotating seats 38, thereby pushing one of the sinkers 1 hinged to them to rise and fall. At the same time, when the drive cam 33 rotates to the hinge point of the second hinge seat 35, the second hinge seat 35 moves downward under its own weight and the pulling force of the hinge rod 39, driving the second support rod 37 to rotate synchronously. The second hinge seat 35 pulls the other sinker 1 connected to it to descend downward through the hinge rod 39 hinged to it, realizing the alternating action of the two sinkers 1 rising and falling.

[0040] At this time, multiple sinkers 2 fixed on the two sinkers 1 rise and fall synchronously with the corresponding sinkers 1, precisely coordinating with the hooking and looping actions of the knitting needle. When the knitting needle hooks the warp yarn to form a new loop, the corresponding sinker 2 rises to press down on the old loop, preventing the old loop from floating up with the knitting needle. When the knitting needle completes the formation of the new loop, the corresponding sinker 2 descends to assist the old loop in smoothly detaching from the knitting needle, ensuring continuous loop formation and regular fabric texture.

[0041] Reference Figure 2 as well as Figure 3 The cooling mechanism 4 includes a cooling box 41, a bidirectional screw 42, a piston plate 43, a conveying assembly 44, a shifting assembly 45, and a triggering assembly 46.

[0042] A support frame 53 is fixedly installed on the warp knitting machine, and a connecting rod is fixedly installed on the support frame 53. The connecting rod is fixedly installed on the cooling box 41. A bidirectional screw 42 is rotatably installed on the cooling box 41. There are two piston plates 43. The outer side of the bidirectional screw 42 is provided with two external threads with opposite directions. The two piston plates 43 are threaded to the corresponding external threads, and both piston plates 43 are slidably installed in the cooling box 41. The cooling box 41 is connected to an inlet pipe, and a control valve is provided on the outer side of the inlet pipe to facilitate the opening and closing of the inlet pipe. A support block 47 is fixedly installed on the cooling box 41, and the bidirectional screw 42 is rotatably installed on the support block 47 to make the bidirectional screw 42 more stable when rotating.

[0043] The conveying assembly 44 is mounted on the cooling tank 41 and is used to convey the coolant in the cooling tank 41 to the guide assembly 5 for lubrication, cooling, and temperature reduction. The shifting assembly 45 is mounted on the warp knitting machine and is used to drive the bidirectional screw 42 to rotate when the drive assembly 3 is started. The triggering assembly 46 is mounted on the cooling tank 41 and is used to trigger the shifting assembly 45 to work in order to achieve lubrication, cooling, and temperature reduction of the guide assembly 5.

[0044] During operation, the triggering component 46 generates a trigger signal, which in turn triggers the shifting component 45 to start working. Under the triggering action, the shifting component 45 drives the bidirectional screw 42 to rotate with the drive shaft 31. The bidirectional screw 42 rotates stably under the support of the support block 47 and the cooling box 41, driving the two piston plates 43 to slide relative to each other along the inner wall of the cooling box 41. As the two piston plates 43 move towards each other, the internal cavity volume of the cooling box 41 decreases, and the coolant in the cavity is squeezed. The control valve on the outside of the inlet pipe is in the closed state, and the coolant cannot flow back from the inlet pipe. Under the pressure, it is then directed to the guide component 5 of the warp knitting machine through the conveying component 44, continuously lubricating, cooling and reducing the temperature of the guide component 5.

[0045] Reference Figure 4 as well as Figure 5 The guide assembly 5 includes a guide cylinder 52 and a guide rod 51. The guide cylinder 52 is fixedly mounted on the support frame 53, and the guide rod 51 is fixedly mounted on the settling seat 1, and the guide rod 51 is slidably mounted inside the guide cylinder 52. The guide rod 51 has a delivery cavity 54 inside, and multiple infusion holes 55 are formed on the surface of the guide rod 51, all of which communicate with the delivery cavity 54.

[0046] The delivery assembly 44 includes a suction pipe 441 and a delivery pipe 442. An arc-shaped block 443 is fixedly installed on the cooling tank 41, and the suction pipe 441 is fixedly installed on the arc-shaped block 443. The inlet of the suction pipe 441 is connected to the cooling tank 41, and the inlet of the delivery pipe 442 is connected to the outlet of the suction pipe 441. The outlet of the delivery pipe 442 is connected to the delivery chamber 54, thereby facilitating the delivery of coolant to the delivery chamber 54 and the discharge of coolant from the delivery hole 55, allowing the coolant to flow between the guide rod 51 and the guide cylinder 52 for lubrication, cooling, and temperature reduction. A one-way valve structure is provided at the connection between the suction pipe 441 and the cooling tank 41 to prevent coolant backflow. The one-way valve structure is a conventional technical means, so it will not be described in detail here.

[0047] Reference Figure 4 A collection assembly 6 for collecting used coolant is mounted on the guide rod 51. The collection assembly 6 includes a collection plate 61 and a telescopic cover 62.

[0048] The collecting plate 61 is fixedly installed on the guide rod 51. One end of the telescopic cover 62 is fixedly installed on the guide cylinder 52, and the other end of the telescopic cover 62 is fixedly installed on the collecting plate 61. The collecting plate 61, the guide cylinder 52, and the telescopic cover 62 together form a collecting chamber 63 to facilitate the collection of used coolant. When the guide rod 51 moves, the telescopic cover 62 moves along with it, thereby squeezing the collecting chamber 63 and re-transporting the coolant in the collecting chamber 63 between the guide rod 51 and the guide cylinder 52 to achieve repeated lubrication, cooling, and temperature reduction.

[0049] During operation, when the two piston plates 43 move towards each other, the internal volume of the cooling tank 41 decreases, and the coolant inside the tank is squeezed to generate pressure. Under the pressure, the coolant enters the delivery pipe 442 through the suction pipe 441. The one-way valve structure at the connection between the suction pipe 441 and the cooling tank 41 effectively prevents the coolant from flowing back, ensuring that the coolant can be delivered in a directional manner. Subsequently, the coolant enters the delivery chamber 54 inside the guide rod 51 through the outlet of the delivery pipe 442, and is then evenly discharged through multiple delivery holes 55 on the surface of the guide rod 51, flowing to the mating gap between the guide rod 51 and the guide cylinder 52, thereby effectively reducing the temperature between the guide rod 51 and the guide cylinder 52 and ensuring the smooth operation of the guide assembly 5.

[0050] Meanwhile, the guide rod 51 always reciprocates within the guide cylinder 52. When the guide rod 51 moves, it synchronously drives the collecting plate 61 fixed on it to move. The collecting plate 61 pulls the telescopic cover 62 to extend and retract synchronously, causing the collecting plate 61 to move closer to the guide cylinder 52. At this time, the telescopic cover 62 is compressed, which squeezes the collecting chamber 63 formed by the collecting plate 61, the guide cylinder 52 and the telescopic cover 62. This squeezes the used coolant collected in the chamber back to the gap between the guide rod 51 and the guide cylinder 52, thus achieving repeated lubrication, cooling and temperature reduction of the coolant.

[0051] Reference Figure 3 The shift assembly 45 includes a shift shaft 451, a synchronization structure 453, and a shift ring 452. The synchronization structure 453 includes two synchronization pulleys 4531 and a synchronization belt 4532.

[0052] The shift shaft 451 is rotatably mounted on the warp knitting machine. One of the synchronous pulleys 4531 is connected to the bidirectional screw 42 via a spline, and the other synchronous pulley 4531 is connected to the shift shaft 451 via a spline. The outer drive sleeves of the two synchronous pulleys 4531 are equipped with the same synchronous belt 4532, so that the shift shaft 451 is synchronously driven to rotate when the bidirectional screw 42 rotates.

[0053] A shift disc 454 is fixedly mounted on one end of the bidirectional screw 42 near the synchronous pulley 4531. A shift groove 455 matching the shift ring 452 is provided on the side of the shift disc 454 near the shift ring 452. The shift ring 452 is fixedly mounted on the synchronous pulley 4531 on the shift shaft 451. Both synchronous pulleys 4531 have annular grooves 456, and a shift bracket 457 is slidably mounted within the annular grooves 456. The shift bracket 457 is connected to the trigger assembly 46 to drive the shift assembly 45, so that when the drive shaft 31 rotates, it drives the bidirectional screw 42 to rotate synchronously.

[0054] Reference Figure 6 The trigger assembly 46 includes a protective plate 461, a starting plate 462, a connecting plate 463, a trigger half-ring 464, a gear and rack structure 467, a trigger plate 465, and a force-applying rod 466. The gear and rack structure 467 includes two racks 4672 and a gear 4671.

[0055] A protective plate 461 is fixedly mounted on the cooling box 41. The protective plate 461 has an activation hole 4611 and a trigger hole 4612. An activation plate 462 is slidably mounted within the activation hole 4611, and a trigger plate 465 is slidably mounted within the trigger hole 4612. Rectangular blocks 4613 are fixedly mounted on the outer sides of both the activation plate 462 and the trigger plate 465 to limit their movement.

[0056] One end of the starter plate 462 is fixedly mounted on one of the racks 4672, and one end of the trigger plate 465 is fixedly mounted on the other rack 4672. A transmission roller 468 is rotatably mounted between the protective plate 461 and the cooling box 41. A gear 4671 is fixedly mounted on the transmission roller 468 and meshes with the two racks 4672, so that the starter plate 462 and the trigger plate 465 form a reverse linkage.

[0057] The other end of the starting plate 462 is fixedly installed on the connecting plate 463. A trigger half-ring 464 is fixedly installed on the inner side of the connecting plate 463. The trigger half-ring 464 is attached to the outer side of the guide rod 51 to push the connecting plate 463 to move when the guide rod 51 undergoes slight deformation due to thermal expansion.

[0058] The two ends of the force-applying rod 466 are respectively hinged to the connecting plate 463 and the trigger plate 465. The protective plate 461 is fixedly installed with the hinge shaft 469. The force-applying rod 466 is hinged to the hinge shaft 469, thereby dividing the force-applying rod 466 into a long lever arm and a short lever arm, thus forming a lever structure. Through the lever arm amplification effect, the small displacement of the guide rod 51 transmitted to the trigger half-ring 464 is amplified into a larger displacement of the trigger plate 465.

[0059] Reference Figure 4The cooling box 41 is equipped with a limiting assembly 7 for limiting and guiding the movement of the connecting plate 463. The limiting assembly 7 includes a limiting block 71 and a limiting telescopic column 72.

[0060] The limiting block 71 is fixedly installed on the cooling box 41. One end of the limiting telescopic column 72 is fixedly installed on the limiting block 71, and the other end of the limiting telescopic column 72 is fixedly installed on the connecting plate 463. A compression spring 73 is sleeved on the outside of the limiting telescopic column 72. One end of the compression spring 73 is connected to the connecting plate 463, and the other end of the compression spring 73 is connected to the limiting block 71. The compression spring 73 drives the connecting plate 463 and the trigger half-ring 464 to always tend to approach the guide rod 51.

[0061] During operation, as the settling mechanism continues to work, the guide rod 51 of the guide assembly 5 and the guide cylinder 52 frequently rub against each other, generating a large amount of heat. The guide rod 51 expands due to the heat, its outer diameter increases, and it generates an outward pushing force on the trigger half-ring 464 that is attached to the outside. The pushing force overcomes the elastic force of the compression spring 73, pushing the trigger half-ring 464 to move away from the guide rod 51. The trigger half-ring 464 drives the connecting plate 463 to move synchronously. The connecting plate 463 pulls the starting plate 462 to slide along the starting hole 4611 of the protective plate 461. The starting plate 462 drives the rack 4672 connected to it to move. Since the rack 4672 meshes with the gear 4671, the gear 4671 rotates synchronously with the movement of the rack 4672, thereby driving the other rack 4672 to move in the opposite direction. The other rack 4672 pulls the trigger plate 465 to slide along the trigger hole 4612, triggering the trigger. The starter plate 465 drives the shift bracket 457 connected to it to slide along the annular groove 456 of the synchronous pulley 4531. The shift bracket 457 drives the shift ring 452 to move synchronously, so that the shift ring 452 is engaged in the shift groove 455 of the shift disc 454, realizing the transmission connection between the shift shaft 451 and the shift disc 454. Since the shift disc 454 is fixedly connected to the double-acting screw 42, the transmission connection between the shift shaft 451 and the double-acting screw 42 is realized. At this time, the power of the drive assembly 3 is transmitted to the double-acting screw 42, driving the double-acting screw 42 to rotate at a constant speed, driving the two piston plates 43 to slide towards each other along the inner wall of the cooling box 41, generating a squeezing force on the coolant. Under the pressure, the coolant is continuously transported to the sliding mating part of the guide assembly 5 through the conveying assembly 44, realizing the lubrication, cooling and temperature reduction of the guide rod 51 and the guide cylinder 52 to prevent the guide rod 51 from getting stuck when moving.

[0062] When the temperature of the guide rod 51 decreases and it shrinks to its normal size, the pushing force of the guide rod 51 on the trigger half-ring 464 disappears. The elastic force of the compression spring 73 pushes the connecting plate 463 and the trigger half-ring 464 to reset. The connecting plate 463 drives the starting plate 462 and the force lever 466 to reset. The force lever 466 drives the trigger plate 465, the rack 4672 and the shift bracket 457 to reset. The shift ring 452 disengages from the shift groove 455. The transmission connection between the shift shaft 451 and the bidirectional screw 42 is disconnected. The bidirectional screw 42 stops rotating, and the lubrication and cooling action is paused. This achieves on-demand lubrication and cooling, ensuring the cooling effect while avoiding coolant waste.

[0063] Based on the same inventive concept, embodiments of the present invention provide a control method for the settling mechanism of a double needle bed warp knitting machine, comprising the following steps: Step S10: Obtain the real-time temperature information of the guide component 5.

[0064] The real-time temperature information of guide component 5 refers to the real-time temperature data of guide component 5 during its operation, which can be collected in real time by the temperature sensor installed on the equipment.

[0065] Step S11: Determine whether the mating part of the guide rod 51 and the guide cylinder 52 is in a high-temperature lubrication and cooling state based on the comparison relationship between the real-time temperature information and the preset reference temperature information, and collect the deformation of the guide assembly.

[0066] The reference temperature information refers to the normal operating temperature of the guide assembly 5, which is obtained and set by the operator through testing experiments on the normally operating equipment. The guide assembly deformation refers to the degree of deformation caused by the thermal expansion of the guide assembly 5 during operation, which can be collected by a deformation sensor installed on the equipment. By comparing the real-time temperature information with the reference temperature information, it is determined whether the mating part between the guide rod 51 and the guide cylinder 52 needs lubrication and cooling due to high temperature.

[0067] Step S12: When the deformation of the guide component reaches the preset reference deformation, the shift component 45 is triggered to work in conjunction with the cooling mechanism 4, and the piston plate 43 is controlled to squeeze the coolant at a preset squeezing rate to continuously deliver the coolant to the space between the guide rod 51 and the guide cylinder 52 for lubrication, cooling and temperature reduction.

[0068] The reference deformation refers to the maximum allowable deformation value of the guide assembly 5 under normal operation, which is obtained and set by the operator through testing experiments on the components of the guide assembly 5 under normal operation. The extrusion rate refers to the extrusion speed of the piston plate 43 when extruding coolant, which is set by the operator and is determined by the rotation speed of the drive shaft 31.

[0069] When the deformation of the guide component reaches the reference deformation, the guide component 5 will expand, causing the guide rod 51 and the guide cylinder 52 to fit tightly together. This will cause the settling seat 1 to jam when it moves. Therefore, by triggering the shift component 45 and the cooling mechanism 4 through the trigger component 46, the drive shaft 31 will rotate, causing the bidirectional screw 42 to rotate synchronously. This will control the piston plate 43 to squeeze the coolant at the extrusion rate, and continuously transport the coolant in the cooling box 41 to the space between the guide rod 51 and the guide cylinder 52 through the conveying component 44 for lubrication, cooling and temperature reduction.

[0070] Step S13: When the deformation of the guide component does not reach the preset reference deformation, the control shift component 45 disconnects the transmission and the cooling mechanism 4 stops supplying liquid.

[0071] If the deformation value of the guide component does not reach the reference deformation, it indicates that the guide component 5 is in normal working condition. At this time, it is not necessary to lubricate and cool the guide component 5, thereby controlling the shift component 45 to disconnect the transmission and the cooling mechanism 4 to stop the liquid supply.

[0072] The method for handling excessively high coolant temperature in the collection chamber 63 includes the following steps: Step S21: Collect the actual temperature of the coolant in the collecting chamber 63, the volume of the coolant in the collecting chamber 63, and the initial temperature of the coolant in the cooling tank 41.

[0073] The actual temperature refers to the real-time temperature of the coolant currently remaining in the collection chamber 63, which can be obtained through a temperature sensor installed on the equipment. The collection volume refers to the total capacity of the coolant currently stored in the collection chamber 63, which can be obtained through a level sensor installed in the collection chamber 63. The initial temperature refers to the temperature of the coolant in the cooling tank 41 before it participates in circulation and is under standard conditions, which can be obtained through a temperature sensor installed in the cooling tank 41.

[0074] Step S22: Match the deformation infusion volume according to the deformation of the guide component.

[0075] The deformation fluid delivery volume refers to the volume of coolant adapted to the actual deformation of the guide component 5 to meet its lubrication, cooling, and temperature reduction requirements. The deformation fluid delivery volume can be obtained by inputting the collected deformation of the guide component 5 into a preset database. This database is established by conducting multiple deformation tests on the guide component 5 under standard operating conditions, collecting the lubrication, cooling, and temperature reduction requirements corresponding to different actual deformations, and establishing a mapping relationship between deformation and coolant volume.

[0076] Step S23: Determine the theoretical temperature of the mixed coolant based on the initial temperature, actual temperature, pool volume, and deformed delivery volume.

[0077] The theoretical temperature refers to the expected coolant temperature after the high-temperature coolant in the collection chamber 63 is mixed with the coolant at the initial temperature delivered by the cooling tank 41 according to the corresponding volumes. The theoretical temperature can be calculated by inputting parameters such as the initial temperature, actual temperature, collection volume, and deformation delivery volume into the heat balance calculation formula.

[0078] Step S24: When the theoretical temperature is higher than the preset reference working fluid temperature, all the coolant in the collecting chamber 63 is discharged to the collection tank, and the coolant of the deformed fluid delivery volume is delivered to the guide assembly 5.

[0079] The reference operating fluid temperature refers to the critical value of the coolant temperature that ensures the normal operation of the equipment's lubrication, cooling, and heat dissipation system. It is preset by the operator.

[0080] If the theoretical temperature of the mixed coolant is higher than the reference working temperature, it indicates that the coolant temperature in the collecting chamber 63 is too high. Direct mixing will affect the lubrication and cooling effect of the equipment. In this case, a complete draining and replenishment of coolant is required. This involves controlling the pump to drain the entire volume of coolant from the collecting chamber 63 and transport it to the collection tank. Simultaneously, the conveying component 44 delivers a matching volume of coolant at its initial temperature to the guiding component 5 to ensure the normal operation of the lubrication and cooling system. The drained coolant will also be filtered through a filter screen in the collection tank and stored for subsequent recycling.

[0081] Step S25: When the theoretical temperature is not higher than the reference working fluid temperature, a portion of the coolant in the collecting chamber 63 is discharged to the collection tank at a preset discharge rate, and coolant of deformed volume is delivered to the guide assembly 5.

[0082] The discharge volume refers to the amount of coolant that meets the requirements discharged from the collecting chamber 63, which is set by the operator according to the actual needs of the equipment operation.

[0083] If the theoretical temperature of the mixed coolant is not higher than the reference working temperature, it means that the temperature of the coolant in the collecting chamber 63 is within an acceptable range and there is no need to drain all the coolant. At this time, the pump is started to drain part of the coolant. At the same time, the conveying component 44 delivers the coolant of the deformed conveying volume to the guiding component 5.

[0084] Using the above method, it is not necessary to drain all the coolant in the collecting chamber 63, which reduces coolant waste and lowers the consumable costs of equipment operation.

[0085] In this embodiment, the collection box is fixedly installed on the cooling box 41, and the liquid pump is installed on the cooling box 41 to transport the coolant in the collection chamber 63 to the collection box. The collection box is detachably installed with a filter screen by bolts to filter impurities in the extracted coolant.

[0086] The method for draining coolant from the collection tank includes the following steps: Step S31: Obtain the real-time volume inside the cooling box 41.

[0087] The real-time volume refers to the actual volume of coolant currently remaining in the cooling tank 41. The real-time volume is obtained in real time through the liquid level sensor built into the cooling tank 41.

[0088] Step S32: Determine the amount of deformable infusion solution supplied based on the deformable infusion volume.

[0089] The deformation fluid supply refers to the total volume of coolant that the cooling tank 41 needs to deliver to the guide component 5 to meet the lubrication, cooling and temperature reduction requirements of the guide component 5. The deformation fluid supply can be obtained by inputting the deformation fluid volume into the database in step S22.

[0090] Step S33: When the real-time volume is less than the deformation infusion supply, collect the temperature of the recovered coolant in the collection tank.

[0091] The recovered liquid temperature refers to the real-time temperature of the coolant stored in the collection tank and discharged from the collection chamber 63. The recovered liquid temperature is obtained through a temperature sensor built into the collection tank.

[0092] If the real-time volume value inside the cooling tank 41 is less than the deformation fluid supply, it indicates that the amount of coolant in the cooling tank 41 is insufficient. It is necessary to recover coolant from the collection tank to replenish it or manually add coolant to the cooling tank 41. If it is not possible to add coolant manually in time, the recovered coolant from the collection tank should be used to replenish the cooling tank 41 first.

[0093] Before transferring the recovered coolant from the collection tank to the cooling tank 41, the temperature of the recovered coolant in the collection tank needs to be measured to avoid the temperature of the recovered coolant in the collection tank being too high, which would affect the normal use of the coolant in the cooling tank 41.

[0094] Step S34: When the temperature of the recovered liquid is lower than the reference working liquid temperature, all the coolant in the collection tank is transferred to the cooling tank 41.

[0095] If the temperature of the recovered coolant in the collection tank is lower than the reference working temperature, it means that the temperature of the recovered coolant meets the requirements for lubrication, cooling and temperature reduction, and it can be directly recycled. At this time, the coolant in the collection tank is transported to the cooling tank 41 by the suction pump to replenish the liquid volume.

[0096] Step S35: When the temperature of the recovered liquid is not lower than the reference working liquid temperature, the theoretical threshold volume is obtained based on the real-time volume, the reference working liquid temperature, the recovered liquid temperature, and the initial temperature.

[0097] The theoretical threshold volume refers to the maximum volume of recovered coolant that can be safely delivered to the cooling tank 41 without causing abnormal lubrication cooling temperature when the recovered coolant temperature is too high. The theoretical threshold volume is calculated by inputting the real-time volume, reference working coolant temperature, recovered coolant temperature, and initial temperature into the heat balance formula.

[0098] If the temperature of the recovered coolant in the collection tank is not lower than the reference working temperature, it indicates that the temperature of the recovered coolant is too high. Directly recovering all of it will affect the lubrication, cooling and temperature reduction effect. At this time, based on the real-time volume, reference working temperature, recovered coolant temperature and initial temperature, the theoretical threshold volume that can be recovered is calculated, and the maximum threshold is set for subsequent recovery operations.

[0099] Step S36: Determine the replenishment volume based on the deformation infusion supply and real-time volume.

[0100] The replenishment volume refers to the difference between the current liquid volume of the cooling tank 41 and the supply of deformation fluid, that is, the amount of coolant that needs to be replenished to the cooling tank 41. The replenishment volume can be calculated by subtracting the real-time volume from the supply of deformation fluid.

[0101] Step S37: When the replenished volume is lower than the theoretical threshold volume, the theoretical threshold volume is transported to the cooling box 41.

[0102] If the replenished volume is lower than the theoretical threshold volume, it means that the required replenishment volume has not exceeded the maximum threshold set for the recovery operation. At this time, the suction pump will transport the recovered coolant of the theoretical threshold volume to the cooling tank 41, which replenishes the liquid volume and avoids the high temperature coolant from affecting the equipment operation.

[0103] Step S38: When the replenished volume is not lower than the theoretical threshold volume, the machine is stopped and coolant at the initial temperature is added back into the cooling tank 41.

[0104] If the replenished volume is not lower than the theoretical threshold volume, it means that the required replenishment volume exceeds the maximum threshold set by the recovery operation. Continuing to recover will cause the coolant temperature in the cooling tank 41 to be abnormal. At this time, the machine should be stopped and the coolant at the initial temperature should be manually added back into the cooling tank 41 to ensure the safety of the subsequent operation of the equipment.

[0105] In this embodiment, the liquid suction pump is fixedly installed on the collection tank to deliver the coolant in the collection tank to the cooling tank 41.
