Description

Technical Field

[0001] The present application belongs to the technical field of yarn covering machines, and in particular to a yarn bobbin delivery device for yarn covering machines. Background Art

[0002] Covered yarn, also known as wrapped yarn, is a kind of yarn with filament or staple fiber as the core, and another filament or staple fiber yarn is wrapped outside. The outer yarn wraps the core yarn in a spiral manner. The yarn covering machine, also known as the yarn covering machine, is an automated machine that can cover the surface of the core yarn of different materials and shapes with yarn filaments.

[0003] The yarn covering machine needs to use yarn bobbins when winding yarn, and the yarn bobbins need to be put in when using the yarn bobbins. Currently, most yarn bobbins are put in the covering machine before the yarn covering machine is used. The yarn bobbins set on the yarn covering machine become empty bobbins after use. At this time, it is necessary to manually remove the empty bobbins from the yarn covering machine and then replace them with new yarn bobbins.

[0004] The patent with publication number CN111994731 B discloses a bottom plate, a baffle, a first support column, a first rotating shaft, and a delivery plate. The top surface of the delivery plate is provided with a plurality of delivery slots, the top surface of the bottom plate is provided with a right telescopic mechanism, the top surface of the bottom plate is provided with a right receiving mechanism, the top surface of the bottom plate is provided with a left telescopic mechanism, and the top surface of the bottom plate is provided with a left receiving mechanism on the left side of the left telescopic mechanism.

[0005] The above patent releases the yarn bobbins in different directions by setting up the left telescopic mechanism and the right telescopic mechanism. Although the delivery of the yarn bobbins in different directions can be achieved, it relies on the extension and retraction of the two telescopic cylinders to achieve the angle change of the delivery plate, and buffers the yarn bobbins by setting up the transition cylinder. This can easily cause unstable delivery of the yarn bobbins. The sliding speed of the yarn bobbins is related to the inclination angle. If the inclination angle changes too much in a short period of time, the yarn bobbins will move faster, making it impossible to dock with the transition groove on the transition cylinder, resulting in the inability to deliver the yarn bobbins. Improvements are needed. Summary of the invention

[0006] The purpose of this application is to provide a yarn bobbin delivery device for a yarn covering machine, which can solve the above-mentioned problems.

[0007] The purpose of the present application is to provide a yarn bobbin delivery device for a yarn covering machine, comprising a base, a delivery device and a receiving device, wherein the delivery device comprises a support rod arranged on the base, a delivery plate rotatably arranged on the support rod, a plurality of delivery slideways are arranged on the delivery plate, and the receiving device is arranged on both sides of the delivery device and is used to receive the delivered yarn bobbins; and further comprises an adjusting device;

[0008] The adjusting device is arranged on both sides of the support rod and connected to the delivery plate, and is used to adjust the inclination angle of the delivery plate, and can make the angle adjustment of the delivery plate more stable;

[0009] The adjusting device is arranged on the base, and the top of the adjusting device is hinged to the launching plate.

[0010] The above-mentioned yarn bobbin delivery device for a yarn wrapping machine is adopted, and the instability and inaccurate delivery of the traditional equipment during the yarn bobbin delivery process are improved by setting an adjustment device. The adjustment device is arranged on both sides of the support rod and connected to the delivery plate, so that the inclination angle of the delivery plate can be finely and stably adjusted. The setting of the adjustment device makes the delivery plate more stable during the angle adjustment process, avoiding the problem of rapid change of the delivery plate angle due to the extension and contraction of the two telescopic cylinders. This stable adjustment method reduces the shaking of the yarn bobbin during the delivery process and improves the delivery accuracy. At the same time, since the adjustment device can stabilize the inclination angle of the delivery plate, the sliding speed of the yarn bobbin on the delivery slideway becomes more controllable, ensuring that the yarn bobbin can accurately dock with the receiving slot on the receiving device, thereby greatly improving the delivery success rate of the yarn bobbin. In addition, the setting of the adjustment device enables the delivery device to adapt to yarn bobbins of different specifications and weights. By adjusting the inclination angle of the delivery plate, it can be ensured that the yarn bobbin always maintains a stable sliding speed during the delivery process, thereby avoiding delivery problems caused by different yarn bobbin specifications.

[0011] Furthermore, the adjusting device comprises:

[0012] The driver is arranged on the base, and limit assemblies are arranged on both sides of the driver;

[0013] A connecting seat is arranged on the telescopic end of the driver and cooperates with the limit assembly;

[0014] A connecting rod is arranged on the connecting seat, and a stabilizing component connected to the bottom of the launching plate is arranged on the top of the connecting rod;

[0015] Wherein, the connecting seat is slidably arranged on the limiting component.

[0016] The driver is arranged on the base and serves as the power source of the adjusting device, and its telescopic end is connected to the connecting rod through the connecting seat. The limit assemblies arranged on both sides of the driver ensure the stability and accuracy of the connecting seat during the up and down movement, and prevent the displacement or shaking of the connecting seat. The connecting seat is slidably arranged on the limit assemblies, so that the connecting seat can move up and down with the extension and contraction of the driver, while maintaining the linearity and stability of its moving trajectory. The connecting rod is arranged on the connecting seat, and its top is connected to the bottom of the delivery plate through a stabilizing assembly, so as to convert the telescopic movement of the driver into the change of the tilt angle of the delivery plate. At the same time, the stabilizing assembly on the top of the connecting rod ensures the stability and firmness of the delivery plate during the change of the tilt angle, which not only improves the angle adjustment accuracy of the delivery plate, but also enhances the bearing capacity of the delivery plate when subjected to force.

[0017] When the inclination angle of the delivery plate needs to be adjusted, the driver starts to telescope. The extension and retraction of the driver drives the connecting seat to move up and down on the limit assembly, thereby driving the connecting rod to move up and down. Since the top of the connecting rod is connected to the bottom of the delivery plate through a stabilizing assembly, the up and down movement of the connecting rod will be converted into a change in the inclination angle of the delivery plate. By accurately controlling the extension and retraction amount and speed of the driver, the inclination angle of the delivery plate can be accurately adjusted. The extension and retraction of the driver can be controlled by a controller. The controller is a prior art and will not be described in detail here.

[0018] Further: the stabilizing component comprises:

[0019] The upper seat is arranged at the bottom of the launching plate;

[0020] The lower seat body is rotatably connected to the upper seat body via a rotating shaft;

[0021] The cylinder is arranged on the lower seat and is arc-shaped, its cross section is circular, a sliding space is arranged inside, one end is closed, and the other end is opened;

[0022] A sliding rod is arranged at the bottom of the delivery plate and is arc-shaped;

[0023] A first buffer member is disposed on the rotating shaft and connected to the cylinder and the sliding rod;

[0024] Among them, the cylinder and the sliding rod cooperate with each other, and the end of the sliding rod away from the delivery plate extends into the sliding space. The two form a telescopic structure and can be telescoped as the angle of the delivery plate changes. There are two groups of sliding rods and cylinders, located on both sides of the rotating shaft.

[0025] The upper seat body is arranged at the bottom of the delivery plate and is fixedly connected to the delivery plate. The lower seat body and the upper seat body are rotatably connected by setting a rotating shaft, so that the upper seat body (i.e., the delivery plate) can change the tilt angle relative to the lower seat body. The cylinder body is arranged on the lower seat body and is arc-shaped, and its cross-section is circular, and a sliding space is arranged inside. One end of the cylinder body is closed, and the other end is provided with an opening for accommodating a sliding rod. The sliding rod is arranged at the bottom of the delivery plate and is arc-shaped, matching the arc shape of the cylinder body. One end of the sliding rod away from the delivery plate extends into the sliding space of the cylinder body, and the two form a telescopic structure. The first buffer member is arranged on the rotating shaft and is connected to the cylinder body and the sliding rod. When the delivery plate changes its tilt angle, the first buffer member will deform, thereby providing a first heavy damping buffering effect.

[0026] The telescopic structure formed by the sliding rod and the cylinder achieves a second damping effect when the inclination angle of the delivery plate changes. When the delivery plate is tilted, the sliding rod will perform a corresponding stretching or compression movement in the sliding space of the cylinder. Since there are two sets of sliding rods and cylinders, located on both sides of the rotating shaft, no matter which direction the delivery plate is tilted, there will be a set of sliding rods and cylinders in a stretching or compression state, thereby providing a stable damping effect.

[0027] The telescopic structure formed by the sliding rod and the cylinder and the deformation of the first buffer provide a stable damping force, effectively reducing the impact and vibration during the tilting process of the delivery plate. No matter which direction the delivery plate tilts, the stabilizing component can provide an effective damping effect to ensure the stability and delivery accuracy of the equipment, thereby achieving a double damping effect when the tilt angle of the delivery plate changes, further improving the stability and delivery accuracy of the equipment.

[0028] Furthermore, the first buffer is a torsion spring, one end of which is connected to a portion of the cylinder close to the opening, and the other end of which is connected to an end of the sliding rod away from the cylinder.

[0029] The torsion spring is used as the first buffer, one end of which is connected to the part of the cylinder close to the opening, and the other end is connected to the end of the sliding rod away from the cylinder, so that the torsion spring can provide a stable damping effect when the inclination angle of the delivery plate changes. One end of the torsion spring is fixedly connected to the part of the cylinder close to the opening, and this connection point can be regarded as the fixed end of the torsion spring. The other end is connected to the end of the sliding rod away from the cylinder, and this connection point will move with the extension and contraction of the sliding rod, so it can be regarded as the movable end of the torsion spring.

[0030] When the launch plate remains horizontal, the torsion spring is unstressed, and the relative position between its two connection points remains unchanged. However, when the launch plate begins to tilt, the sliding rod will stretch or compress in the sliding space of the cylinder, causing the movable end of the torsion spring to rotate relative to the fixed end. The rotation of the torsion spring will generate a restoring torque, which will try to pull the sliding rod back to its original position, thereby slowing down the speed change during the launch plate's tilting process. This restoring torque is the damping force provided by the torsion spring, which helps stabilize the launch plate's tilt angle and prevent it from suddenly accelerating or decelerating.

[0031] In addition to the damping force provided by the torsion spring, the telescopic structure between the sliding rod and the cylinder also forms another damping buffering effect. When the sliding rod is telescoped in the cylinder, it will generate friction with the inner wall of the cylinder, and this friction will also slow down the speed change during the tilting process of the delivery plate. Therefore, the torsion spring in the stabilization component and the telescopic structure of the sliding rod / cylinder together constitute a dual damping buffer system, which can effectively absorb and slow down the impact and vibration during the tilting process of the delivery plate, and improve the stability and delivery accuracy of the equipment.

[0032] Furthermore, the limiting component includes:

[0033] The guide plates are arranged on both sides of the driver, and each guide plate is provided with a sliding groove for the connecting seat to slide;

[0034] The second buffer is arranged on the guide vertical plate, and its two ends are respectively connected to the guide vertical plate and the connecting seat;

[0035] A guide limiting structure, which is arranged on the guide vertical plate and cooperates with the connecting seat, and is used to limit and guide the connecting seat;

[0036] Wherein, a mounting groove for mounting the second buffer member is arranged on the guide vertical plate, and the mounting groove is located below the sliding groove.

[0037] The limiting assembly is mainly composed of a guide plate, a second buffer and a guide limiting structure, which together realize the limitation, guidance and stabilization of the movement process of the connecting seat. The guide plates are arranged on both sides of the driver, providing sliding tracks for the connecting seat. Each guide plate is provided with a sliding groove for the sliding of the connecting seat, and the sliding groove ensures the linearity and stability of the connecting seat during the up and down movement. The second buffer is arranged on the guide plate, and its two ends are respectively connected to the guide plate and the connecting seat. This buffer plays a role in further stabilizing the movement of the connecting seat. When the connecting seat slides in the sliding groove, the second buffer will absorb and reduce the impact and vibration of the connecting seat, so that the movement of the connecting seat is smoother. An installation groove for installing the second buffer is provided on the guide plate. This installation groove is located below the sliding groove, which ensures that the second buffer can work normally without interfering with the sliding of the connecting seat.

[0038] The guide limit structure is arranged on the guide vertical plate and cooperates with the connecting seat to ensure that the connecting seat will not deviate from the predetermined track during the sliding process, while limiting the maximum movement range of the connecting seat to prevent angular deviation due to excessive movement.

[0039] Furthermore, the second buffer member includes a first damper and a second damper arranged at an interval and a tension spring arranged between the first damper and the second damper. The telescopic ends of the first damper and the second damper are connected to the connecting seat, and a telescopic groove for the tension spring to be telescoped is also arranged between the two mounting grooves.

[0040] The second buffer is mainly composed of a first damper, a second damper and a tension spring, which together provide a stable and adjustable damping effect for the movement of the connecting seat. The first damper and the second damper are arranged on the guide vertical plate at intervals, and their telescopic ends are connected to the connecting seat. When the connecting seat slides in the sliding groove of the guide vertical plate, the first damper and the second damper will perform corresponding telescopic movements according to the moving speed and direction of the connecting seat. The telescopic movement of the damper will generate a damping force, thereby slowing down the moving speed of the connecting seat, thereby achieving buffering and stabilization of the movement of the connecting seat. The tension spring is arranged between the first damper and the second damper, and its two ends are respectively connected to the connecting seat and the bottom of the telescopic groove. An additional restoring force can be provided. When the connecting seat moves, the tension spring will expand and contract with the expansion and contraction of the damper, thereby generating a pulling force opposite to the moving direction of the connecting seat. This pulling force helps to maintain the stability of the connecting seat and prevent it from shaking or deviating from the predetermined track due to external interference during movement.

[0041] At the same time, mounting grooves for installing the first damper and the second damper are provided on the guide vertical plate. These mounting grooves are located below the sliding groove, ensuring that the dampers can work normally without interfering with the sliding of the connecting seat. In addition, a telescopic groove for the extension and contraction of the tension spring is provided between the two mounting grooves. This telescopic groove provides sufficient space for the tension spring to freely extend and contract during the movement of the connecting seat without any hindrance. The first damper, the second damper and the tension spring in the second buffer work together to provide a stable and adjustable damping buffering effect for the movement of the connecting seat, which not only improves the overall performance and reliability of the equipment, but also reduces the risk of inaccurate bobbin delivery caused by unstable movement of the connecting seat. In addition, by adjusting the damping coefficient of the damper and the stiffness of the tension spring, the buffering effect of the second buffer can be precisely controlled according to actual needs to meet the buffering requirements under different working conditions.

[0042] Furthermore, the guide limiting structure includes:

[0043] A first guide groove, disposed on the sliding groove;

[0044] A second guide groove is arranged on the sliding groove and is symmetrical with the first guide groove about the telescopic groove;

[0045] A first sliding block is disposed on the connecting seat and is slidably matched with the first guide groove;

[0046] A second sliding block is disposed on the connecting seat and is slidably matched with the second guide groove;

[0047] The first slider and the second slider are both rotatably arranged on the connecting seat, and the first slider and the second slider are both provided with a cylinder at the bottom, and the cylinder is slidably matched with the first guide groove and the second guide groove.

[0048] The first guide groove and the second guide groove are respectively arranged on the sliding groove of the guide vertical plate, and the two are symmetrical about the telescopic groove. The two guide grooves provide a stable sliding track for the first slider and the second slider on the connecting seat, ensuring the linearity and stability of the connecting seat during movement. The first slider and the second slider are respectively arranged on the connecting seat, and slide with the first guide groove and the second guide groove, so that the connecting seat can be guided and restricted by the guide groove during movement to prevent it from deviating from the predetermined track. At the same time, the first slider and the second slider can be rotatably arranged on the connecting seat, so that they can change their angles within a certain range to adapt to the complex situations that the connecting seat may encounter during movement, such as the subsequent cooperation with the limit angle.

[0049] A cylinder is provided at the bottom of the first slider and the second slider, and the cylinder is located at the rotating connection and the end of the slider. The cylinder slides with the first guide groove and the second guide groove, which improves the sliding smoothness between the slider and the guide groove, ensuring that the slider will not separate from the guide groove during movement, and also allows the subsequent first slider, the second slider and the limit angle to cooperate more smoothly.

[0050] In addition, through the rotatable setting, the first slider and the second slider can change their angles within a certain range, thereby cooperating with the subsequent limit rotation angle, so that the connecting seat can flexibly adapt to different tilt angles and limit requirements during the movement. When the connecting seat reaches the tilt angle of the limit position, the first slider and the second slider can rotate to cooperate with the corresponding limit rotation angle to ensure that the connecting seat can accurately stay in the predetermined position, thereby playing a stabilizing role.

[0051] Furthermore, the guide limiting structure also includes:

[0052] A limiting protrusion is arranged on the sliding groove and is located between the first guide groove and the second guide groove;

[0053] The limiting corner includes a first corner arranged at the end of the first guide groove and a second corner arranged at the end of the second guide groove, and the first slider and the second slider cooperate with the first corner and the second corner respectively;

[0054] The limiting groove includes a left half groove provided on the first sliding block and a right half groove provided on the second sliding block;

[0055] The position-limiting guide comprises a first elastic member arranged on the first sliding block and a second elastic member arranged on the second sliding block;

[0056] A locking groove adapted to the limiting protrusion is formed between the limiting guide and the limiting groove, and contact grooves for contacting the limiting protrusion are arranged at both ends of the first elastic member and the second elastic member.

[0057] During adjustment, one driver extends and the other contracts. Under normal circumstances, that is, when the delivery plate is in a horizontal state, the connection seat is located between the limiting corner and the limiting protrusion. When the delivery is completed and the connection seat is contracted, by setting the limiting protrusion, when the connection seat moves down, the first slider and the second slider are separated from the limiting corner. At this time, the first slider and the second slider are close to each other, and the first elastic member and the second elastic member are also close to each other and contact each other. As the first slider and the second slider gradually move down, the limiting protrusion contacts the contact groove and enters the locking groove. At this time, the left half groove and the right half groove clamp the limiting protrusion, and the limiting protrusion contacts the contact groove close to one side of the locking groove. At this time, the positions of the first slider and the second slider are fixed by the limiting protrusion and cannot move down further, that is, the position of the connection seat is fixed and cannot move down further. At this time, the angle of the delivery plate is just at the lowest point, avoiding excessive adjustment of the angle.

[0058] In the extended state, when the connecting seat moves upward, it drives the first slider and the second slider to move upward. Under the influence of the upward force, the first slider and the second slider rotate outward respectively, and the limiting protrusion disengages from the locking groove. As the connecting seat gradually moves upward until it moves to the top, the first slider and the second slider enter the first corner and the second corner respectively. The angles of the first corner and the second corner are bent outward, which can hook the cylinders at the upper ends of the first slider and the second slider, thereby limiting the positions of the first slider and the second slider. At this time, the connecting seat cannot move upward, and the angle of the launch plate is exactly at the highest position, avoiding excessive adjustment of the angle.

[0059] In addition, since the first elastic member and the second elastic member of the limiting guide are both elastic, even if the two are in contact before contacting the limiting protrusion, they will not hinder the movement of the first slider and the second slider. When the limiting protrusion contacts the first elastic member and the second elastic member, it will ensure the normal movement of the connecting seat by compressing the two.

[0060] Furthermore, the limiting protrusion is cylindrical, and there is a gap between the top of the limiting protrusion and the inner side of the connecting seat and the tension spring.

[0061] The cylindrical setting can make the limiting protrusion better contact with the first elastic part and the second elastic part, and can also be better clamped by the left half groove and the right plate groove, so as to better cooperate with the locking groove. At the same time, by setting a gap between the top of the limiting protrusion and the inner side of the connecting seat and the tension spring, it can avoid collision with the limiting protrusion when the connecting seat moves and when the tension spring is expanded and contracted, thereby ensuring smooth movement.

[0062] The beneficial effects of this application are:

[0063] 1. The setting of the adjustment device makes the delivery plate more stable during the angle adjustment process, avoiding the problem of rapid changes in the delivery plate angle caused by the extension and retraction of the two telescopic cylinders. This stable adjustment method reduces the shaking of the yarn bobbin during delivery and improves the accuracy of delivery. The sliding speed of the yarn bobbin on the delivery slideway is also more controllable, ensuring that the yarn bobbin can accurately dock with the receiving slot on the receiving device, thereby greatly improving the success rate of yarn bobbin delivery;

[0064] 2. The telescopic structure formed by the sliding rod and the cylinder achieves a second damping effect when the inclination angle of the delivery plate changes. When the delivery plate is tilted, the sliding rod will perform a corresponding stretching or compression movement in the sliding space of the cylinder. Since there are two sets of sliding rods and cylinders, located on both sides of the shaft, no matter which direction the delivery plate is tilted, there will be a set of sliding rods and cylinders in a stretching or compression state, thereby providing a stable damping effect;

[0065] 3. The first damper, the second damper and the tension spring in the second buffer member work together to provide a stable and adjustable damping effect for the movement of the connecting seat, which not only improves the overall performance and reliability of the equipment, but also reduces the risk of inaccurate bobbin delivery caused by unstable movement of the connecting seat;

[0066] 4. The first slider and the second slider are rotatable, so that the angle can be changed within a certain range, thereby cooperating with the limit angle, so that the connecting seat can flexibly adapt to different tilt angles and limit requirements during movement. When the connecting seat reaches the tilt angle of the limit position, the first slider and the second slider can rotate to cooperate with the corresponding limit angle to ensure that the connecting seat can accurately stay in the predetermined position and play a stabilizing role;

[0067] 5. Through the cooperation of the limiting protrusion, the limiting groove and the limiting guide, the position of the first slider and the second slider can be limited, that is, the position of the connecting seat can be fixed so that it cannot move further downward, thereby avoiding excessive adjustment of the angle of the launch plate.

[0079] The yarn bobbin delivery device for the yarn covering machine provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0080] Embodiment 1:

[0081] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a yarn bobbin delivery device for a yarn covering machine, comprising a base 100, a delivery device 110 and a receiving device 120, wherein the delivery device 110 comprises a support rod 111 arranged on the base 100, a delivery plate 112 rotatably arranged on the support rod 111, a plurality of delivery slideways 113 are arranged on the delivery plate 112, and the receiving device 120 is arranged on both sides of the delivery device 110 and is used to receive the delivered yarn bobbins; and further comprises an adjusting device 200;

[0082] The adjustment device 200 is disposed on both sides of the support rod 111 and connected to the delivery plate 112, and is used to adjust the inclination angle of the delivery plate 112, and can make the angle adjustment of the delivery plate 112 more stable;

[0083] The adjusting device 200 is disposed on the base 100 , and the top of the adjusting device 200 is hinged to the launching plate 112 .

[0084] In some implementations of the embodiments of the present application, Figure 1As shown, the above-mentioned yarn bobbin delivery device for a yarn wrapping machine is adopted, and the instability and inaccurate delivery of the traditional equipment during the yarn bobbin delivery process are improved by setting the adjustment device 200. The adjustment device 200 is arranged on both sides of the support rod 111 and connected to the delivery plate 112, so that the inclination angle of the delivery plate 112 can be finely and stably adjusted. The setting of the adjustment device 200 makes the delivery plate 112 more stable during the angle adjustment process, avoiding the problem of rapid change of the angle of the delivery plate 112 due to the extension and contraction of the two telescopic cylinders. This stable adjustment method reduces the shaking of the yarn bobbin during the delivery process and improves the accuracy of delivery. At the same time, since the adjustment device 200 can stabilize the inclination angle of the delivery plate 112, the sliding speed of the yarn bobbin on the delivery slide 113 becomes more controllable, ensuring that the yarn bobbin can accurately dock with the receiving slot on the receiving device 120, thereby greatly improving the delivery success rate of the yarn bobbin. In addition, the setting of the adjustment device 200 enables the delivery device to adapt to yarn bobbins of different specifications and weights. By adjusting the inclination angle of the delivery plate 112, it can be ensured that the yarn bobbin always maintains a stable sliding speed during the delivery process, thereby avoiding delivery problems caused by different yarn bobbin specifications.

[0085] Embodiment 2:

[0086] An embodiment of the present application provides a yarn bobbin delivery device for a yarn wrapping machine. In addition to the above-mentioned technical features, the yarn bobbin delivery device for a yarn wrapping machine in the embodiment of the present application also includes the following technical features.

[0087] like Figures 2 to 4 As shown, the adjustment device 200 includes:

[0088] The driver 210 is disposed on the base 100, and limit assemblies 400 are disposed on both sides thereof;

[0089] The connecting seat 220 is disposed on the telescopic end of the driver 210 and cooperates with the limiting assembly 400;

[0090] The connecting rod 230 is disposed on the connecting seat 220, and a stabilizing component 300 connected to the bottom of the delivery plate 112 is disposed on the top thereof;

[0091] The connecting seat 220 is slidably disposed on the limiting assembly 400 .

[0092] In the embodiment of the present application, the driver 210 is arranged on the base 100, as the power source of the adjustment device 200, and its telescopic end is connected to the connecting rod 230 through the connecting seat 220. The limiting components 400 arranged on both sides of the driver 210 ensure the stability and accuracy of the connecting seat 220 during the up and down movement, and prevent the displacement or shaking of the connecting seat 220. The connecting seat 220 is slidably arranged on the limiting component 400, so that the connecting seat 220 can move up and down with the expansion and contraction of the driver 210, while maintaining the linearity and stability of its movement trajectory. The connecting rod 230 is arranged on the connecting seat 220, and its top is connected to the bottom of the delivery plate 112 through the stabilizing component 300, so as to convert the telescopic movement of the driver 210 into the tilt angle change of the delivery plate 112. At the same time, the stabilizing component 300 on the top of the connecting rod 230 ensures the stability and firmness of the delivery plate 112 during the tilt angle change, which not only improves the angle adjustment accuracy of the delivery plate 112, but also enhances the bearing capacity of the delivery plate 112 when subjected to force.

[0093] When the inclination angle of the delivery plate 112 needs to be adjusted, the driver 210 starts to telescope. The telescopic movement of the driver 210 drives the connecting seat 220 to move up and down on the limiting assembly 400, thereby driving the connecting rod 230 to move up and down. Since the top of the connecting rod 230 is connected to the bottom of the delivery plate 112 through the stabilizing assembly 300, the up and down movement of the connecting rod 230 will be converted into a change in the inclination angle of the delivery plate 112. By accurately controlling the telescopic amount and speed of the driver 210, the inclination angle of the delivery plate 112 can be accurately adjusted. The telescopic movement of the driver 210 can be controlled by a controller, which is a prior art and will not be described in detail here.

[0094] Embodiment 3:

[0095] An embodiment of the present application provides a yarn bobbin delivery device for a yarn wrapping machine. In addition to the above-mentioned technical features, the yarn bobbin delivery device for a yarn wrapping machine in the embodiment of the present application also includes the following technical features.

[0096] like Figure 3 and Figure 4 As shown, the stabilizing assembly 300 includes:

[0097] The upper seat 310 is disposed at the bottom of the delivery plate 112;

[0098] The lower seat body 320 is rotatably connected to the upper seat body 310 by setting a rotating shaft 321;

[0099] The cylinder 330 is disposed on the lower seat 320 and is arc-shaped, with a circular cross section, a sliding space 331 disposed inside, one end of which is closed and the other end of which is open;

[0100] The sliding rod 340 is disposed at the bottom of the delivery plate 112 and is arc-shaped;

[0101] The first buffer member 350 is disposed on the rotating shaft 321 and connected to the cylinder 330 and the sliding rod 340;

[0102] Among them, the cylinder 330 and the sliding rod 340 cooperate with each other, and the end of the sliding rod 340 away from the delivery plate 112 extends into the sliding space 331. The two form a telescopic structure and can be telescoped as the angle of the delivery plate 112 changes. There are two groups of sliding rods 340 and cylinder 330, which are located on both sides of the rotating shaft 321.

[0103] In the embodiment of the present application, the upper seat 310 is arranged at the bottom of the delivery plate 112 and is fixedly connected to the delivery plate 112. The lower seat 320 and the upper seat 310 are rotatably connected by setting a rotating shaft 321, so that the upper seat 310 (i.e., the delivery plate 112) can change the tilt angle relative to the lower seat 320. The cylinder 330 is arranged on the lower seat 320 and is arc-shaped, and its cross-section is circular, and a sliding space 331 is arranged inside. One end of the cylinder 330 is closed, and the other end is provided with an opening for accommodating the sliding rod 340. The sliding rod 340 is arranged at the bottom of the delivery plate 112 and is arc-shaped, matching the arc of the cylinder 330. The end of the sliding rod 340 away from the delivery plate 112 extends into the sliding space 331 of the cylinder 330, and the two form a telescopic structure. The first buffer 350 is arranged on the rotating shaft 321 and is connected to the cylinder 330 and the sliding rod 340. When the delivery plate 112 changes its tilt angle, the first buffer member 350 will be deformed, thereby providing a first heavy damping buffering effect.

[0104] The telescopic structure formed by the sliding rod 340 and the cylinder 330 realizes a second damping and buffering effect when the inclination angle of the delivery plate 112 changes. When the delivery plate 112 is tilted, the sliding rod 340 will perform a corresponding stretching or compression movement in the sliding space 331 of the cylinder 330. Since two groups of sliding rods 340 and cylinders 330 are provided, located on both sides of the rotating shaft 321, no matter which direction the delivery plate 112 is tilted, there will be a group of sliding rods 340 and cylinders 330 in a stretching or compression state, thereby providing a stable damping and buffering effect.

[0105] The telescopic structure formed by the sliding rod 340 and the cylinder 330 and the deformation of the first buffer 350 provide a stable damping force, effectively reducing the impact and vibration during the tilting process of the delivery plate 112. Regardless of the direction in which the delivery plate 112 tilts, the stabilizing assembly 300 can provide an effective damping effect to ensure the stability and delivery accuracy of the device, thereby achieving a double damping effect when the tilt angle of the delivery plate 112 changes, further improving the stability and delivery accuracy of the device.

[0106] Furthermore, the first buffer member 350 is a torsion spring, one end of which is connected to a portion of the cylinder 330 close to the opening, and the other end of which is connected to an end of the sliding rod 340 away from the cylinder 330 .

[0107] The torsion spring is used as the first buffer member 350, one end of which is connected to the part of the cylinder 330 close to the opening, and the other end is connected to the end of the sliding rod 340 away from the cylinder 330, so that the torsion spring can provide a stable damping effect when the tilt angle of the delivery plate 112 changes. One end of the torsion spring is fixedly connected to the part of the cylinder 330 close to the opening, and this connection point can be regarded as the fixed end of the torsion spring. The other end is connected to the end of the sliding rod 340 away from the cylinder 330, and this connection point will move with the extension and contraction of the sliding rod 340, so it can be regarded as the movable end of the torsion spring.

[0108] When the delivery plate 112 is kept in a horizontal position, the torsion spring is in an unstressed state, and the relative position between its two connection points remains unchanged. However, when the delivery plate 112 begins to tilt, the sliding rod 340 will perform a stretching or compression movement in the sliding space 331 of the cylinder 330, causing the movable end of the torsion spring to rotate relative to the fixed end. The rotation of the torsion spring will generate a restoring torque, which will try to pull the sliding rod 340 back to its original position, thereby slowing down the speed change during the tilting process of the delivery plate 112. This restoring torque is the damping force provided by the torsion spring, which helps to stabilize the tilt angle of the delivery plate 112 and prevent it from suddenly accelerating or decelerating.

[0109] In addition to the damping force provided by the torsion spring, the telescopic structure between the sliding rod 340 and the cylinder 330 also forms another damping buffering effect. When the sliding rod 340 is telescopic in the cylinder 330, it will generate friction with the inner wall of the cylinder 330, and this friction will also slow down the speed change of the delivery plate 112 during the tilting process. Therefore, the torsion spring in the stabilizing assembly 300 and the telescopic structure of the sliding rod 340 / cylinder 330 together constitute a dual damping buffering system, which can effectively absorb and slow down the impact and vibration during the tilting process of the delivery plate 112, thereby improving the stability of the device and the delivery accuracy.

[0110] Embodiment 4:

[0111] An embodiment of the present application provides a yarn bobbin delivery device for a yarn wrapping machine. In addition to the above-mentioned technical features, the yarn bobbin delivery device for a yarn wrapping machine in the embodiment of the present application also includes the following technical features.

[0112] like Figures 5 to 8 As shown, the limiting assembly 400 includes:

[0113] The guide plates 410 are disposed on both sides of the driver 210. Each guide plate 410 is provided with a sliding groove 411 for the connecting seat 220 to slide.

[0114] The second buffer member 420 is disposed on the guide plate 410, and its two ends are respectively connected to the guide plate 410 and the connecting seat 220;

[0115] The guide limiting structure 500 is disposed on the guide vertical plate 410 and cooperates with the connecting seat 220 to limit and guide the connecting seat 220;

[0116] The guide vertical plate 410 is provided with a mounting groove 412 for mounting the second buffer member 420 , and the mounting groove 412 is located below the sliding groove 411 .

[0117] In the embodiment of the present application, the limiting assembly 400 is mainly composed of a guide plate 410, a second buffer 420 and a guide limiting structure 500, which together realize the limitation, guidance and stability of the movement process of the connecting seat 220. The guide plates 410 are arranged on both sides of the driver 210, providing a sliding track for the connecting seat 220. Each guide plate 410 is provided with a sliding groove 411 for the connecting seat 220 to slide. The sliding groove 411 ensures the linearity and stability of the connecting seat 220 during the up and down movement. The second buffer 420 is arranged on the guide plate 410, and its two ends are respectively connected to the guide plate 410 and the connecting seat 220. This buffer plays a role in further stabilizing the movement of the connecting seat 220. When the connecting seat 220 slides in the sliding groove 411, the second buffer 420 will absorb and slow down the impact and vibration of the connecting seat 220, so that the movement of the connecting seat 220 is more stable. The guide vertical plate 410 is provided with a mounting groove 412 for mounting the second buffer member 420 . The mounting groove 412 is located below the sliding groove 411 , thereby ensuring that the second buffer member 420 can work normally without interfering with the sliding of the connecting seat 220 .

[0118] The guide limit structure 500 is disposed on the guide vertical plate 410 and cooperates with the connecting seat 220 to ensure that the connecting seat 220 does not deviate from the predetermined track during the sliding process, while limiting the maximum movement range of the connecting seat 220 to prevent angular deviation due to excessive movement.

[0119] Furthermore, the second buffer member 420 includes a first damper 421 and a second damper 422 that are spaced apart and a tension spring 423 that is disposed between the first damper 421 and the second damper 422. The telescopic ends of the first damper 421 and the second damper 422 are connected to the connecting seat 220, and a telescopic groove 424 for the tension spring 423 to be telescoped is also disposed between the two mounting grooves 412.

[0120] In some embodiments of the present application, the second buffer member 420 is mainly composed of a first damper 421, a second damper 422 and a tension spring 423, which together provide a stable and adjustable damping effect for the movement of the connecting seat 220. The first damper 421 and the second damper 422 are arranged on the guide vertical plate 410 at intervals, and their telescopic ends are connected to the connecting seat 220. When the connecting seat 220 slides in the sliding groove 411 of the guide vertical plate 410, the first damper 421 and the second damper 422 will perform corresponding telescopic movement according to the moving speed and direction of the connecting seat 220. The telescopic movement of the damper will generate a damping force, thereby slowing down the moving speed of the connecting seat 220, thereby achieving buffering and stabilization of the movement of the connecting seat 220. The tension spring 423 is arranged between the first damper 421 and the second damper 422, and its two ends are respectively connected to the connecting seat 220 and the bottom of the telescopic groove 424. An additional restoring force can be provided. When the connecting seat 220 moves, the tension spring 423 will expand and contract as the damper expands and contracts, thereby generating a pulling force opposite to the moving direction of the connecting seat 220. This pulling force helps to maintain the stability of the connecting seat 220 and prevents it from shaking or deviating from the predetermined track due to external interference during movement.

[0121] At the same time, the guide vertical plate 410 is provided with mounting grooves 412 for mounting the first damper 421 and the second damper 422. These mounting grooves 412 are located below the sliding groove 411, ensuring that the dampers can work normally without interfering with the sliding of the connecting seat 220. In addition, a telescopic groove 424 for the tension spring 423 to be extended and retracted is provided between the two mounting grooves 412. This telescopic groove 424 provides a sufficient space for the tension spring 423 to be able to freely extend and retract without any hindrance during the movement of the connecting seat 220. The first damper 421, the second damper 422 and the tension spring 423 in the second buffer member 420 work together to provide a stable and adjustable damping and buffering effect for the movement of the connecting seat 220, which not only improves the overall performance and reliability of the equipment, but also reduces the risk of inaccurate bobbin delivery due to unstable movement of the connecting seat 220. In addition, by adjusting the damping coefficient of the damper and the stiffness of the tension spring 423, the buffering effect of the second buffer member 420 can be precisely controlled according to actual needs to meet the buffering needs under different working conditions.

[0122] Embodiment 5:

[0123] An embodiment of the present application provides a yarn bobbin delivery device for a yarn wrapping machine. In addition to the above-mentioned technical features, the yarn bobbin delivery device for a yarn wrapping machine in the embodiment of the present application also includes the following technical features.

[0124] like Figures 5 to 8 As shown, the guide and limiting structure 500 includes:

[0125] A first guide groove 510 is disposed on the sliding groove 411;

[0126] The second guide groove 520 is disposed on the sliding groove 411 and is symmetrical with the first guide groove 510 about the telescopic groove 424;

[0127] A first sliding block 530 is disposed on the connecting seat 220 and slidably cooperates with the first guide groove 510;

[0128] A second sliding block 540 is disposed on the connecting seat 220 and slidably cooperates with the second guide groove 520;

[0129] The first slider 530 and the second slider 540 are both rotatably disposed on the connecting seat 220 , and the first slider 530 and the second slider 540 are both provided with 550 at the bottom, and the cylinder 550 is slidably matched with the first guide groove 510 and the second guide groove 520 .

[0130] In the embodiment of the present application, the first guide groove 510 and the second guide groove 520 are respectively arranged on the sliding groove 411 of the guide vertical plate 410, and the two are symmetrical about the telescopic groove 424. The two guide grooves provide a stable sliding track for the first slider 530 and the second slider 540 on the connecting seat 220, ensuring the linearity and stability of the connecting seat 220 during movement. The first slider 530 and the second slider 540 are respectively arranged on the connecting seat 220, and slide with the first guide groove 510 and the second guide groove 520, so that the connecting seat 220 can be guided and restricted by the guide groove during movement to prevent it from deviating from the predetermined track. At the same time, the first slider 530 and the second slider 540 can be rotatably arranged on the connecting seat 220, so that they can change their angles within a certain range to adapt to the complex situations that the connecting seat 220 may encounter during movement, such as the subsequent cooperation with the limit angle 570.

[0131] A cylinder 550 is provided at the bottom of the first slider 530 and the second slider 540. The cylinder 550 is located at the rotating connection and the end of the slider. The cylinder 550 is slidably matched with the first guide groove 510 and the second guide groove 520, which improves the sliding smoothness between the slider and the guide groove, ensuring that the slider will not separate from the guide groove during movement, and also allows the subsequent first slider 530, the second slider 540 and the limit corner 570 to cooperate more smoothly.

[0132] In addition, through the rotatable setting, the first slider 530 and the second slider 540 can change their angles within a certain range, thereby cooperating with the subsequent limit angle 570, so that the connection base 220 can flexibly adapt to different tilt angles and limit requirements during the movement. When the connection base 220 reaches the tilt angle of the extreme position, the first slider 530 and the second slider 540 can rotate to cooperate with the corresponding limit angle 570 to ensure that the connection base 220 can accurately stay at the predetermined position, playing a stabilizing role.

[0133] Embodiment 6:

[0134] An embodiment of the present application provides a yarn bobbin delivery device for a yarn wrapping machine. In addition to the above-mentioned technical features, the yarn bobbin delivery device for a yarn wrapping machine in the embodiment of the present application also includes the following technical features.

[0135] like Figures 5 to 8 As shown, the guide limiting structure 500 also includes:

[0136] The limiting protrusion 560 is disposed on the sliding groove 411 and is located between the first guide groove 510 and the second guide groove 520;

[0137] The limiting corner 570 includes a first corner 571 disposed at the end of the first guide groove 510 and a second corner 572 disposed at the end of the second guide groove 520. The first slider 530 and the second slider 540 cooperate with the first corner 571 and the second corner 572 respectively.

[0138] The limiting groove 580 includes a left half groove 581 provided on the first slider 530 and a right half groove 582 provided on the second slider 540;

[0139] The limiting guide member 590 includes a first elastic member 591 disposed on the first slider 530 and a second elastic member 592 disposed on the second slider 540;

[0140] A locking groove 600 adapted to the limiting protrusion 560 is formed between the limiting guide 590 and the limiting groove 580 , and contact grooves 610 for contacting the limiting protrusion 560 are provided at both ends of the first elastic member 591 and the second elastic member 592 .

[0141] In the embodiment of the present application, during adjustment, one of the drivers 210 extends and the other contracts. Under normal circumstances, that is, when the delivery plate 112 is in a horizontal state, the connecting seat 220 is located between the limiting corner 570 and the limiting protrusion 560. When the first and second sliders 530 and 540 are in contact with each other, the first and second elastic members 591 and 592 are also in contact with each other. As the first and second sliders 530 and 540 gradually move downward, the limiting protrusion 560 contacts the contact groove 610 and enters the locking groove 600. At this time, the left half groove 581 and the right half groove 582 clamp the limiting protrusion 560, and the limiting protrusion 560 contacts the contact groove 610 close to the locking groove 600. At this time, the positions of the first and second sliders 530 and 540 are fixed by the limiting protrusion 560 and cannot move further downward, that is, the position of the connecting seat 220 is fixed and cannot move further downward. At this time, the angle of the delivery plate 112 is just at the lowest point, avoiding excessive adjustment of the angle.

[0142] In the extended state, when the connecting seat 220 moves upward, the first slider 530 and the second slider 540 are driven to move upward. Under the influence of the upward force, the first slider 530 and the second slider 540 are respectively rotated outward, and the limiting protrusion 560 is disengaged from the locking groove 600. As the connecting seat 220 gradually moves upward until it moves to the top, the first slider 530 and the second slider 540 enter the first corner 571 and the second corner 572 respectively. The angles of the first corner 571 and the second corner 572 are bent outward, which can hook the cylinder 550 at the upper ends of the first slider 530 and the second slider 540, thereby limiting the position of the first slider 530 and the second slider 540. At this time, the connecting seat 220 cannot move upward, and the angle of the delivery plate 112 is exactly at the highest point, avoiding excessive adjustment of the angle.

[0143] In addition, since the first elastic member 591 and the second elastic member 592 of the limiting guide member 590 are both elastic, even if the two are in contact before contacting the limiting protrusion 560, they will not hinder the movement of the first slider 530 and the second slider 540. When the limiting protrusion 560 contacts the first elastic member 591 and the second elastic member 592, it will ensure the normal movement of the connecting seat 220 by compressing the two.

[0144] Furthermore, the limiting protrusion 560 is cylindrical, and there is a gap between the top of the limiting protrusion 560 and the inner side of the connecting seat 220 and the tension spring 423.

[0145] In some embodiments of the present application, the cylindrical setting can make the limiting protrusion 560 better contact the first elastic member 591 and the second elastic member 592, and can also be better clamped by the left half groove 581 and the right plate groove, so as to better cooperate with the locking groove 600. At the same time, by providing a gap between the top of the limiting protrusion 560 and the inner side of the connecting seat 220 and the tension spring 423, it can avoid collision with the limiting protrusion 560 when the connecting seat 220 moves and the tension spring 423 is extended and retracted, thereby ensuring smooth movement.

[0146] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element.

The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
